 National Pollutant Discharge
 Elimination System—Regulations for
 Revision of the Water Pollution Control
 Program Addressing Storm Water
 Discharges

 AGENCY: Environmental Protection
 Agency (EPA).
 ACTION: Final rule.

 SUMMARY: Today's regulations (Phase II)
 expand the existing National Pollutant
 Discharge Elimination System (NPDES)
 storm water program (Phase I) to
 address storm water discharges from
 small municipal separate storm sewer
 systems (MS4s) (those serving less than
 100,000 persons) and construction sites
 that disturb one to five acres. Although
 these sources are automatically
 designated by today's rule, the rule,,
 allows for the exclusion of certain
 sources from the national program based
 on a demonstration  of the lack of impact
 on water quality, as well as the
 inclusion of others based on a higher
 likelihood of localized adverse impact
 on water quality. Today's regulations
 also exclude from the NPDES  program
 storm water discharges from industrial
 facilities that have "no exposure" of
 industrial activities  or materials to
 storm water. Finally, today's rule
 extends from August 7, 2001 until
 March 10, 2003  the deadline by which
 certain industrial facilities owned by
 small MS4s must obtain coverage under
 an NPDES permit. This rule establishes
 a cost-effective,  flexible approach for
 reducing environmental  harm by storm
 water discharges from many point
 sources of storm water that are currently
 unregulated.
  EPA believes that  the implementation
 of the six minimum  measures  identified
 for small MS4s should significantly
 reduce pollutants in urban storm water
 compared to  existing levels in a cost-
 effective manner. Similarly, EPA
believes that implementation of Best
 Management Practices (BMP) controls at
 small construction sites will also result
 in a significant reduction in pollutant
 discharges and an improvement in
 surface water quality. EPA believes this
rule will result in monetized financial,
recreational and health benefits, as well
as benefits that EPA  has been unable to
monetize. Expected benefits include
reduced scouring and erosion of
streambeds, improved aesthetic quality
  of waters, reduced eutrophication of
  aquatic systems, benefit to wildlife and
  endangered and threatened species,
.  tourism benefits, biodiversity benefits
  and reduced costs for siting reservoirs.
  In addition, the costs of industrial storm
  water controls will decrease due to the
  exclusion of storm water discharges
  from facilities where there is "no
  exposure" of storm water to industrial
  activities and materials.
  DATES: This regulation is effective on
  February 7,  2000. The incorporation by
  reference of the rainfall erosivity factor
  publication listed in the rule is
  approved by the Director of the Federal
  Register as of February 7, 2000. For
  judicial review purposes, this final rule
  is promulgated as of 1:00 p.m. Eastern
  Standard Time, on December 22,1999
  as provided in 40 CFR 23.2.

I. Background

A. Proposed Rule and Pre-Proposal
Outreach
   On January 9, 1998 (63 FR 1536), EPA
proposed to expand the National
Pollutant Discharge Elimination System
(NPDES) storm water program to
include storm water discharges from
municipal separate storm sewer systems
(MS4s) and construction sites that were
smaller than those previously included
in the program. The proposal also
addressed industrial sources that have
"no exposure" of industrial activities
and materials to storm water. Today,
EPA is promulgating a final rule to
implement most of the proposed
revisions with minor changes based on
public comments received on the
proposal. Today's final rule also extends
the deadline by which certain industrial
facilities operated by municipalities of
less than 100,000 population must be
covered by a NPDES permit; the
  deadline is changed from August 7,
  2001 until March 10, 2003.
    In 1972, Congress amended the
  Federal Water Pollution Control Act
  (commonly referred to as the Clean
  Water Act (CWA)) to prohibit the
  discharge of any pollutant to waters of
  the United States from a point source
  unless the discharge is authorized by an
  NPDES permit. The NPDES program is
  a program designed to track point
  sources and require the implementation
  of the controls necessary to minimize
  the discharge  of pollutants. Initial
  efforts to improve water quality under
  the NPDES program primarily focused
  on reducing pollutants in industrial
  process wastewater and municipal
  sewage. These discharge sources were
  easily identified as responsible for poor,
  often drastically degraded, water quality
  conditions.
   As pollution control measures for
  industrial process wastewater and
 municipal sewage were implemented
 and refined, it became increasingly
 evident that more diffuse sources of
 water pollution were also significant
 causes of water quality impairment.
 Specifically, storm water runoff
 draining large  surface areas, such as
 agricultural and urban land, was found
 to be a major cause of water quality
 impairment, including the
 nonattainment of designated beneficial
 uses.
   In 1987, Congress amended the CWA
 to require implementation, in two
 phases, of a comprehensive national
 program for addressing storm water
 discharges. The first phase of the
 program, commonly referred to as
 "Phase I," was promulgated on
 November 16, 1990 (55 FR 47990).
 Phase I requires NPDES permits for
 storm water discharge from a large
 number of priority sources including
 municipal separate storm sewer systems
 ("MS4s") generally serving populations
 of 100,000 or more and several
 categories of industrial activity,
 including construction sites that disturb
 five or more acres of land.
  Today's rule, which is the second
 phase of the storm water program,
 expands the existing program to include
 discharges of storm water from smaller
 municipalities  in urbanized areas and
 from construction sites that disturb
 between one and five acres of land.
 Today's rule allows certain sources to be
 excluded from the national program
 based on a demonstrable lack of impact
 on water quality. The rule also allows
 other sources not automatically
regulated on a national basis to be
 designated for inclusion based on
 increased likelihood for localized
adverse impact on water quality.

-------
 68724    Federal Register/Vol.  64,  No. 235/Wednesday, December's,  1999/Rules and Regulations
 Today's rule also conditionally excludes
 storm water discharges from industrial
 facilities that have "no exposure" of
 industrial activities or materials to
 storm water. Today's rule and the effort
 that led to its development are
 commonly referred to as "Phase II." On
 August 7,1995, EPA promulgated a
 final rule that required facilities to be
 regulated under Phase II to apply for a
 NPDES permit by August 7, 2001,
 unless the NPDES permitting authority
 designates them as requiring a permit by
 an earlier date. (60 FR 40230). That rule
 is referred to as "the Interim Phase II
 Rule." Today's rule replaces the Interim
 Phase II rule.
   EPA performed extensive outreach
 and worked with a variety of
 stakeholders prior to proposing today's
 rule. On September 9,1992, EPA
 published a notice requesting
 information and public comment on
 how to prepare regulations under CWA
 section 402(p)(6) (see 57 FR 41344). The
 notice identified three sets of issues
 associated with developing new NPDES
 storm water regulations: (1) How should
 EPA identify unregulated sources of
 storm water to protect water quality, (2)
 what types of control strategies should
 EPA develop for these sources, and (3)
 what are appropriate deadlines for
 implementing new requirements. The
 notice recognized that potential sources
 for coverage under the section 402(p)(6)
 regulations would fall into two main
 categories: municipal separate storm
 sewer systems and individual
 (commercial and residential) sources.
 EPA received more than 130 comments
 on the September 9,1992, notice. For
 further discussion of the comments
 received, see Storm Water Discharges
 Potentially Addressed by Phase II of the
 National Pollutant Discharge
 Elimination  System: Report to Congress
 (EPA, 1995a), pp. 1-21 to 1-22, and
 Appendix J (which provides a detailed
 summary of the comments received as
 they relate to the specific issues raised
 in the notice).
  In early 1993, the Rensselaerville
 Institute and EPA held public and
 expert meetings to assist in developing
 and analyzing options for identifying
 unregulated  sources and possible
 controls. The report on the 1993
 meetings identified two options that
 were favored by the various groups that
 participated. One option was a program
 that allowed States to select sources to
be controlled in a manner consistent
with criteria developed by EPA. A
second option was a tiered approach
under which EPA would select high
priority sources for control by NPDES
permits and  States would select other
sources for control under a State water
 quality program other than the NPDES
 program. For additional details see the
 "Report on the EPA Storm Water
 Management Program (Rensselaerville
 Study)," Appendix I of Storm Water
 Discharges Potentially Addressed by
 Phase II of the National Pollutant
 Discharge Elimination System: Report to
 Congress (EPA, 1995 a).
   EPA also conducted outreach with
 representatives of small entities in
 conjunction with the convening of a
 Small Business Advocacy Review Panel
 under the Small Business Regulatory
 Enforcement Fairness Act (SBREFA).
 This process is discussed in section IV.E
 of today's preamble. For additional
 background see the discussion in the
 preamble to the proposal for today's
 rule.
   To assist EPA by providing advice
 and recommendations regarding the
 urban municipal wet weather water
 pollution control program, EPA
 established the Urban Wet Weather
 Flows Federal Advisory Committee
 (hereinafter, "FACA Committee") under
 the Federal Advisory Committee Act
 (FACA). The Office of Management and
 Budget approved the charter for the
 FACA Committee on March 10,1995.
 The FACA Committee provided a forum
 for identifying and addressing issues
 associated with water quality impacts
 from storm water sources.
  The FACA Committee established two
 subcommittees: the Storm Water Phase
 II FACA Subcommittee and the Sanitary
 Sewer Overflows (SSOs) FACA
 Subcommittee. Consistent with the
 requirements of FACA, the membership
 of both the FACA Committee and  the
 subcommittees was balanced among
 EPA's various outside stakeholder
 interests, including representatives from
 municipalities, States, Indian Tribes,
 EPA, industrial and commercial sectors,
 agriculture, and environmental and
 public interest groups.
  The Storm Water Phase II FACA
 Subcommittee ("Subcommittee") met
 fourteen times between September 1995
 and June 1998. The 32 Subcommittee
 members discussed possible regulatory
 frameworks at these meetings as well as
 during numerous other meetings and
 conference calls. Members of the FACA
 Committee provided views regarding
 the development of the "no exposure"
 provision and other provisions in  drafts
 of the Phase II rule. EPA provided
 Subcommittee members with four
 successive drafts of the proposed rule
 and preamble,  outlines of the rule,
summaries of the written comments
received on each draft, and documents
identifying the changes made to each
 draft. In the course of providing input
to the Committee, individual
 Subcommittee members provided
 significant input and advice that EPA
 considered in the context of public
 comments received. Ultimately, the
 Subcommittee did not provide a written
 report back to the FACA Committee,
 and the FACA Committee did not
 provide written advice and
 recommendations to EPA. The Agency,
 therefore, did not rely on group
 recommendations in developing today's
 rule, but does consider the process to
 have resulted in important public
 outreach.
 B. Water Quality Concerns/
 Environmental Impact Studies and
 Assessments
  Storm water runoff from lands
 modified by human activities can harm
 surface water resources and, in turn,
 cause or contribute to an exceedance of
 water quality standards by changing
 natural hydrologic patterns, accelerating
 stream flows, destroying aquatic habitat,
 and elevating pollutant concentrations
 and loadings. Such runoff may contain
 or mobilize high levels of contaminants,
 such as sediment, suspended solids,
 nutrients (phosphorous and nitrogen),
 heavy metals and other toxic pollutants,
 pathogens, toxins, oxygen-demanding
 substances (organic  material), and
 floatables (U.S. EPA. 1992.
 Environmental Impacts of Storm  Water
 Discharges: A National Profile. EPA
 841-R-92-001. Office of Water.
 Washington, DC). After a rain, storm
 water runoff carries  these pollutants
 into nearby streams, rivers, lakes,
 estuaries, wetlands,  and oceans. The
 highest concentrations of these
 contaminants often are contained in
 "first flush" discharges, which occur
 during the first major storm after an
 extended dry period (Schueler, T.R.
 1994. "First Flush of Stormwater
 Pollutants Investigated in Texas." Note
 28.  Watershed Protection Techniques
 1(2)). Individually and combined, these
 pollutants impair water quality,
 threatening designated beneficial uses
 and causing habitat alteration or
 destruction.
  Uncontrolled storm water discharges
 from areas of urban development and
 construction activity negatively impact
receiving waters by changing the
physical, biological,  and chemical
composition of the water, resulting in an
unhealthy environment for aquatic
organisms, wildlife,  and humans. The
following sections discuss the studies
and data that  address and support this
finding.
  Although water quality problems also
can occur from agricultural storm water
discharges and return flows from
irrigated agriculture, this area of

-------
           Federal Register/Vol. 64, No.  235/Wednesday,  December 8, 1999/Rules  and Regulations    68725
concern is statutorily exempted from
regulation as a point source under the
Clean Water Act and is not discussed
here. (See CWA section 502(14)). Other
storm water sources not specifically
identified in the regulations may be of
concern in certain areas and can be
addressed on a case-by-case (or
category-by-category) basis through the
NPDES designation authority preserved
by CWA section 402(p)(2)(6), as well as
today's rule.
1. Urban Development
  Urbanization alters the natural
infiltration capability of the land and
generates a host of pollutants that are
associated with the activities of dense
populations, thus causing an increase in
storm water runoff volumes and
pollutant loadings in storm water
discharged to receiving waterbodies
(U.S. EPA, 1992). Urban development
increases the amount of impervious
surface in a watershed as farmland,
forests, and meadowlands with natural
infiltration characteristics are converted
into buildings with rooftops, driveways,
sidewalks, roads, and parking lots with
virtually no ability to absorb storm
water.  Storm water and snow-melt
runoff wash over these impervious
areas, picking up pollutants along the
way while gaining speed and volume
because of their inability to disperse and
filter into the ground. What results are
storm water flows that are higher in
volume, pollutants, and temperature
than the flows in less impervious areas,
which have more natural vegetation and
soil to  filter the runoff (U.S. EPA, 1997.
Urbanization and Streams: Studies of
Hydrologic Impacts. EPA 841-R-97-009.
Office  of Water. Washington, DC).
  Studies reveal that the level of
imperviousness in an area strongly
correlates with the quality of the nearby
receiving waters. For example,  a study
in the Puget Sound lowland ecoregion
found that when the level of basin
development exceeded 5 percent of the
total impervious area, the biological
integrity and physical habitat conditions
that are necessary to support natural
biological diversity and complexity
declined precipitously (May, C.W.,  E.B.
Welch, R.R. Homer, J.R. Karr, and B.W.
May. 1997. Quality Indices for
Urbanization Effects in Puget Sound
Lowland Streams, Technical Report No.
154. University of Washington  Water
Resources Series). Research conducted
in numerous geographical areas,
concentrating on various variables and
employing widely different methods,
has revealed a similar conclusion:
stream degradation occurs at relatively
loxv levels of imperviousness, such  as 10
to 20 percent (even as low as 5  to 10
percent according to the findings of the
Washington study referenced above)
(Schueler, T.R. 1994. "The Importance
of Imperviousness." Watershed
Protection Techniques 1(3); May, C.,
R.R. Horner, J.R. Karr, B.W. Mar, and
E.B. Welch. 1997. "Effects Of
Urbanization On Small Streams In The
Puget Sound Lowland Ecoregion."

Life Designated Uses in Urban and
Suburban Watersheds." In Proceedings:

"Assessing Biological Quality and
Limitations to Biological Potential in
Urban and Suburban Watersheds in
Ohio." In Comprehensive Stormwater &•
Aquatic Ecosystem Management
Conference Papers, Auckland, New
Zealand). Furthermore, research has
indicated that few, if any, urban streams
can support diverse benthic
communities at imperviousness levels
of 25 percent or more. An area of
medium density single family homes
can be anywhere from 25 percent to
nearly 60 percent impervious,
depending on the design of the streets
and parking (Schueler, 1994).
  In addition to impervious areas, urban
development creates new pollution
sources as population density increases
and brings with it proportionately
higher levels of car emissions, car
maintenance wastes, pet waste, litter,
pesticides, and household hazardous
wastes, which may be washed into
receiving waters by storm water or
dumped directly into storm drains
designed to discharge to receiving
waters. More people in less space
results in a greater concentration of
pollutants that can be mobilized by, or
disposed into, storm water discharges
from municipal separate storm sewer
systems. A modeling system developed
for the Chesapeake Bay indicated that
contamination of the Bay and its
tributaries from runoff is comparable to,
if not greater than, contamination from
industrial and sewage sources (Cohn-
Lee, R. and D. Cameron. 1992. "Urban
Stormwater Runoff Contamination of
the Chesapeake Bay: Sources and
Mitigation." The Environmental
Professional, Vol. 14).

a. Large-Scale Studies and Assessments
  In support of today's regulatory
designation of MS4s in urbanized areas,
the Agency relied on broad-based
assessments of urban storm water runoff
and related water quality impacts, as
well as more site-specific studies. The
first national assessment of urban runoff
characteristics was completed for the
Nationwide Urban Runoff Program
(NURP) study (U.S. EPA. 1983. Results
of the Nationwide Urban Runoff
Program, Volume 1.—Final Report.
Office of Water. Washington, D.C.). The
NURP study is the largest nationwide
evaluation of storm water discharges,
which includes  adverse impacts and
sources, undertaken to date.
  EPA conducted the NURP study to
facilitate understanding of the nature of
urban runoff from residential,
commercial, and industrial areas.  One
objective of the study was to
characterize the water quality of
discharges from separate storm sewer
systems that drain residential,
commercial, and light industrial
(industrial parks) sites. Storm water
samples from 81 residential and
commercial properties in 22 urban/
suburban areas nationwide were
collected and analyzed during the 5-
year period between 1978 and 1983. The
majority of samples collected in the
study were analyzed for eight
conventional pollutants and three heavy
metals.
  Data collected under the NURP  study
indicated that discharges from separate
storm sewer systems draining runoff
from residential, commercial, and light
industrial areas  carried more than 10
times the annual loadings of total
suspended solids (TSS) than discharges
from municipal  sewage treatment plants
that provide secondary treatment. The
NURP study also indicated that runoff
from residential and commercial areas
carried somewhat higher annual
loadings of chemical oxygen demand
(COD), total lead, and total copper than
effluent from secondary treatment
plants. Study findings showed that fecal
coliform counts  in urban runoff
typically range from tens to hundreds of
thousands per hundred milliliters of
runoff during warm weather conditions,
with the median for all sites being
around 21,000/100 ml. This is generally
consistent with studies that found that
fecal coliform mean values range from
1,600 coliform fecal units (CFU)/100 ml
to 250,000 cfu/100 ml (Makepeace, O.K.,
D.W. Smith, and S.J. Stanley. 1995.

including physical contaminants such
as total solids (76—36,200 mg/L) and

oil and grease (up to 110 mg/L); and

   Monitoring data summarized in the
 NURP study provided important
 information about urban runoff from
 residential, commercial, and light
 industrial areas. The study concluded
 that the quality of urban runoff can be
 affected adversely by several sources of
 pollution that were not directly
 evaluated in the study, including illicit
 discharges, construction site runoff, and
 illegal dumping. Data from the NURP
 study were analyzed further in the U.S.
 Geological Survey (USGS) Urban Storm
 Water Data Base for 22 Metropolitan
 Areas Throughout the United States
 study (Driver, N.E., M.H. Mustard, R.B.
 Rhinesmith, and R.F. Middleburg. 1985.
 U.S. Geological Survey Urban Storm
 Water Data Base for 22 Metropolitan
 Areas Throughout the United States.
. Report No. 85-337 USGS. Lakewood,
 CO). The USGS report summarized
 additional monitoring data compiled
 during the mid-1980s, covering 717
 storm events at 99 sites in 22
 metropolitan areas and documented
 problems associated with metals and
 sediment concentrations in urban storm
 water runoff. More recent reports have
 confirmed the pollutant concentration
 data collected in the NURP study
 (Marsalek, J. 1990. "Evaluation of
 Pollutant Loads from Urban Nonpoint
 Sources." Wat. Sci. Tech. 22(10/11):23-
 30; Makepeace, et al., 1995).
   Commenters argued that the NURP
 study does not support EPA's
 contention that urban activities
 significantly jeopardize attainment of
 water quality standards. One commenter
 argued that the NURP study and the
 1985 USGS study are seriously out of
 date. Because they were issued 10 years
 or more before the implementation of
 the current storm water permit program,
 the data  in those reports do not reflect
 conditions that exist after
 implementation of permits issued by
 authorized States and EPA for storm
 water from construction sites, large
 municipalities, and industrial activities.
   In response, EPA notes that it is not
 relying solely on the NURP study to
 describe current water quality
 impairment. Rather, EPA is citing NURP
 as a source of data on typical pollutant
 concentrations in urban runoff. Recent
 studies have not found significantly
 different pollutant concentrations in
 urban runoff when compared to the
 original  NURP data (see Makepeace, et
 al.,  1995; Marsalek, 1990; and Pitt, et al.,
  1995).
    America's Clean Water—the States'
  Nonpoint Source Assessment
  (Association of State and Interstate
  Water Pollution Control Administrators
  (ASIWPCA). 1985. America's Clean
  Water—The States' Nonpoint Source
Assessment. Prepared in cooperation
with the U.S. EPA, Office of Water,
Washington, DC), a comprehensive
study of diffuse pollution sources
conducted under the sponsorship of the
Association of State and Interstate Water
Pollution Control Administrators
(ASIWPCA) and EPA revealed that 38
States reported urban runoff as a major
cause of designated beneficial use
impairment and 21 States reported
storm water runoff from construction
sites as a major cause of beneficial use
impairment. In addition, the 1996
305(b) Report (U.S. EPA. 1998. The
National Water Quality Inventory, 1996
Report to Congress. EPA 841-R-97-008.
Office of Water. Washington, DC),
provides a national assessment of water
quality based on biennial reports
submitted by the States as required
under CWA section 305(b) of the CWA.
In the CWA 305(b) reports, States,
Tribes, and Territories assess their
individual water quality control
programs by examining the attainment
or nonattainment of the designated uses
assigned to their rivers, lakes, estuaries,
wetlands, and ocean shores. A
designated use is the legally applicable
use specified in a water quality standard
for a watershed, waterbody, or segment
of a waterbody. The designated use is
the desirable use that the water quality
should support. Examples of designated
uses include drinking water supply,
primary contact recreation (swimming),
and aquatic life  support. Each CWA
305(b) report indicates  the assessed
fraction of a State's  waters that are fully
supporting, partially supporting, or not
supporting designated beneficial uses.
   In their reports, States, Tribes, and
Territories first identified and then
assigned the sources of water quality
impairment for each impaired
waterbody using the following
categories: industrial, municipal
sewage, combined sewer overflows,
urban runoff/storm sewers, agricultural,
silvicultural, construction, resource
 extraction, land disposal, hydrologic
 modification, and habitat modification.
 The 1996 Inventory, based on a
 compilation of 60 individual 305(b)
 reports submitted by States, Tribes, and
 Territories, assessed the following
 percentages of total waters nationwide:
 19 percent of river and stream miles; 40
 percent of lake, pond, and reservoir
 acres; 72 percent of estuary square
 miles; and 6 percent of ocean shoreline
 waters. The 1996 Inventory indicated
 that approximately 40  percent of the
 Nation's assessed rivers, lakes, and
 estuaries are impaired. Waterbodies
 deemed as "impaired" are either
partially supporting designated uses or  ,
not supporting designated uses.
  The 1996 Inventory also found urban
runoff/discharges from storm sewers to
be a major source of water quality
impairment nationwide. Urban runoff/
storm sewers were found to be a source
of pollution in 13 percent of impaired
rivers; 21 percent of impaired lakes,
ponds, and reservoirs; and 45 percent of
impaired estuaries (second only to
industrial discharges). In addition,
urban runoff was found to be the
leading cause of ocean impairment for
those ocean miles surveyed.
  In addition, a recent USGS study of
urban watersheds across the United
States has revealed a link between urban
development and contamination of local
waterbodies. The study found the
highest levels of organic contaminants,
known as polycyclic aromatic
hydrocarbons (PAHs) (products of
combustion of wood, grass, and fossil
fuels), in the reservoirs of urbanized
watersheds (U.S. Geological Survey
(USGS). 1998. Research Reveals Link
Between Development and
Contamination in Urban Watersheds.
USGS news release. USGS National
Water-Quality Assessment Program).
  Urban storm water also can contribute
significant amounts of toxicants to
receiving waters. Pitt, et. al. (1993),
found heavy metal concentrations in the
majority of samples analyzed. Industrial
or commercial areas were likely to be
the most significant pollutant source
areas (Pitt, R., R. Field, M. Lalor, M.
Brown 1993. "Urban stormwater toxic
pollutants: assessment, sources, and
treatability" Water Environment
Research, 67(3):260-75).
b. Local and Watershed-Based Studies
   In addition to the large-scale
nationwide studies and assessments, a
number of local and watershed-based
studies from across the country have
documented the detrimental effects of
urban storm water runoff on water
quality. A study of urban streams in
Milwaukee County, Wisconsin, found
local streams to be highly degraded due
primarily to urban runoff, while three
studies in the Atlanta, Georgia, region
were characterized as being "the first
 documentation in the Southeast of the
 strong negative relationship between
 urbanization and stream quality that has
been observed in other ecoregions"
 (Masterson, J. and R. Bannerman. 1994.

 Urban Streams in Milwaukee County,
 Wisconsin." Paper presented at National
 Symposium on Water Quality:

          receiving water effects on aquatic
          organisms associated with urban runoff

         Zealand).
           In Wisconsin, runoff samples were
         collected from streets, parking lots,
         roofs, driveways, and lawns. Source
         areas were broken up into residential,
         commercial, and industrial. Geometric
         mean concentration data for residential
         areas included total solids of about 500-
         800 mg/L from streets and 600 mg/L
         from lawns. Fecal  coliform data from
         residential areas ranged from 34,000 to
         92,000 cfu/100 mL for streets and
         driveways. Contaminant concentration
         data from commercial and industrial
         source areas were lower for total solids
 and fecal coliform, but higher for total
 zinc (Bannerman, R.T., D.W. Owens,
 R.B. Dods, and N.J. Hornewer. 1993.
 "Sources of Pollutants in Wisconsin
 Stormwater." Wat. Sci. Tech. 28(3-
 5):241-59).
   Bannerman, et al. also found that
 streets contribute higher loads of
 pollutants to urban storm water than
 any other residential development
 source. Two small urban residential
 watersheds were evaluated to determine
 that lawns and streets are the largest
 sources of total and dissolved
 phosphorus in the basins (Waschbusch,
 R.J., W.R. Selbig, and R.T. Bannerman.

 Stormwater and Street Dirt from Two
 Urban Residential Basins In Madison,
 Wisconsin, 1994-95." Water Resources
 Investigations Report 99—4021. U.S.
 Geological Survey). A number of other
 studies have indicated that urban
 roadways often contain significant
 quantities of metal elements and solids
 (Sansalone, J.J. and S.G. Buchberger.

 c. Beach Closings/Advisories
  Urban wet weather flows have been
 recognized as the primary sources of
 estuarine pollution in coastal
 communities. Urban storm water runoff,
 sanitary sewer overflows, and combined
 sewer overflows have become the largest
 causes of beach closings in the United
 States in the past three years. Storm
 water discharges from urban areas not
 only pose a threat to the ecological
 environment, they also can substantially
 affect human health. A survey of coastal
 and Great Lakes communities reports
that in 1998, more than 1,500 beach
 closings and advisories were associated
with storm water runoff (Natural
Resources Defense Council. 1999. "A
Guide to Water Quality at Vacation
Beaches" New York, NY).  Other reports
 also document public health, shellfish
 bed, and habitat impacts from storm
 water runoff, including more than 823
 beach closings/advisories issued in 1995
 and more than 407 beach closing/
 advisories issued in 1996 due to urban
 runoff (Natural Resources Defense
 Council. 1996. Testing the Waters

 (Haile, R.W., et. al. 1996. "An

 prepared for the Santa Monica Bay
 Restoration Project) concluded that
 there is a 57 percent higher rate  of
 illness in swimmers who swim adjacent
 to storm drains than in swimmers who
 swim more than 400 yards away from
 storm drains. This and  other studies
 document a relationship between
 gastrointestinal illness in swimmers and
 water quality,  the latter of which can be
 heavily compromised by polluted storm
 water discharges.

 2. Non-Storm Water Discharges Through
 Municipal Storm Sewers
  Studies  have shown that discharges
 from MS4s often include wastes and
 wastewater from non-storm water
 sources. Federal regulations
 (§122.26(b)(2)) define an illicit
 discharge as "* * * any discharge to an
 MS4 that is not composed entirely of
 storm water *  *  *," with some
 exceptions. These discharges are
 "illicit" because municipal storm sewer
 systems are not designed to  accept,
 process, or discharge such wastes.
 Sources of illicit discharges  include, but
 are not limited to: sanitary wastewater;
 effluent from septic tanks; car wash,
 laundry, and other industrial
 wastewaters; improper disposal of auto
 and household toxics, such  as used
 motor oil and pesticides; and spills from
 roadway and other accidents.
  Illicit discharges enter the system
through either direct connections (e.g.,
wastewater piping either mistakenly or
 deliberately connected to the storm
 drains) or indirect connections (e.g.,
infiltration into the MS4 from cracked
sanitary systems, spills  collected by
drain outlets, and paint or used oil
 dumped directly into a drain). The
result is untreated discharges that
contribute high levels of pollutants,
_

-------
68728    Federal Register/Vol. 64, No. 235/Wednesday, December 8, 1999/Rules and Regulations
including heavy metals, toxics, oil and
grease, solvents, nutrients, viruses and
bacteria into receiving waterbodies. The
NURP study, discussed earlier, found
that pollutant levels from illicit
discharges were high enough to
significantly degrade receiving water
quality and threaten aquatic, wildlife,
and human health. The study noted
particular problems with illicit
discharges of sanitary wastes, which can
be directly linked to high bacterial
counts in receiving waters and can be
dangerous to public health.
  Because illicit discharges to MS4s can
create severe widespread contamination
and water quality problems, several
municipalities and urban counties
performed studies to identify and
eliminate such discharges. In Michigan,
the Ann Arbor and Ypsilanti water
quality projects inspected 660
businesses, homes, and other buildings
and identified 14 percent of the
buildings as having improper storm
sewer drain connections. The program
assessment revealed that, on average, 60
percent of automobile-related
businesses, including service stations,
automobile dealerships, car washes,
body shops, and light industrial
facilities, had illicit connections to
storm sewer drains. The program
assessment also showed that a majority .
of the illicit discharges to the storm
sewer system resulted from improper
plumbing and connections, which had
been approved by the municipality
when installed (Washtenaw County
Statutory Drainage Board. 1987. Huron
River Pollution Abatement Program).
  In addition, an inspection of urban
storm water outfalls draining into Inner
Grays, Washington, indicated that 32
percent of these outfalls had dry
weather flows. Of these flows, 21
percent were determined to have
pollutant levels higher than the
pollutant levels expected in typical
urban storm water runoff characterized
in the NURP study (U.S. EPA. 1993.
Investigation of Inappropriate Pollutant
Entries Into Storm Drainage Systems—
A User's Guide. EPA  600/R-92/238.
Office of Research and Development.
Washington, DC). That same document
reports a study in Toronto, Canada, that
found that 59 percent of outfalls from
the MS4  had dry-weather flows.
Chemical tests revealed that 14 percent
of these dry-weather flows were
determined to be grossly polluted.
  Inflows from aging sanitary sewer
collection systems are one of the most
serious illicit discharge-related
problems. Sanitary sewer systems
frequently develop leaks and cracks,
resulting in discharges of pollutants to
receiving waters through separate storm
sewers. These pollutants include
sanitary waste and materials from sewer
main construction (e.g., asbestos
cement, brick, cast iron, vitrified clay).
Municipalities have long recognized the
reverse problem of storm water
infiltration into sanitary sewer
collection systems; this type of
infiltration often disrupts the operation
of the municipal sewage treatment
plant.
  The improper disposal of materials is
another illicit discharge-related problem
that can result in contaminated
discharges from separate storm sewer
systems in two ways. First, materials
may be disposed of directly in a  catch
basin or other storm water conveyance.
Second, materials disposed of on the
ground may either drain directly to a
storm sewer or be washed into a storm
sewer during  a storm event. Improper
disposal of materials to street catch
basins and other storm sewer inlets
often occurs when people mistakenly
believe that disposal to such areas  is an
environmentally sound practice. Part of
the confusion may occur because some
areas are served by combined sewer
systems, which are part of the sanitary
sewer collection system, and people
assume that materials discharged to a
catch basin will reach a municipal
sewage treatment plant. Materials that
are commonly disposed of improperly
include used  motor oil; household toxic
materials;  radiator fluids; and litter,
such as disposable cups, cans, and fast-
food packages. EPA believes that there
has been increasing success in
addressing these problems through
initiatives such as storm drain stenciling
and recycling programs, including
household hazardous waste special
collection days.
  Programs that reduce illicit discharges
to separate storm sewers have improved
water quality  in several municipalities.
For example,  Michigan's Huron River
Pollution Abatement Program found the
elimination of illicit connections caused
a measurable  improvement in the water
quality of the  Washtenaw County storm
sewers and-the Huron River
(Washtenaw County Statutory Drainage
Board, 1987).  In addition, an illicit
detection and remediation program in
Houston, Texas, has significantly
improved  the water quality of Buffalo
Bayou. Houston estimated that illicit
flows from 132  sources had a flow  rate
as high as  500 gal/min. Sources of the
illicit discharges included broken and
plugged sanitary sewer lines, illicit
connections from sanitary lines to storm
sewer lines, and floor drain connections
(Glanton, T., M.T. Garrett, and B.
Goloby. 1992. The Illicit Connection: Is
It the Problem? Wat. Env. Tech. 4(9):63-
8).
3. Construction Site Runoff
  Storm water discharges generated
during construction activities can cause
an array of physical, chemical, and
biological water quality impacts.
Specifically, the biological, chemical,
and physical integrity of the waters may
become severely compromised. Water
quality impairment results, in part,
because a number of pollutants are
preferentially absorbed onto mineral or
organic particles found in fine sediment.
The interconnected process of erosion
(detachment of the soil particles),
sediment transport, and delivery is the
primary pathway for introducing key
pollutants, such as nutrients
(particularly phosphorus), metals, and
organic compounds into aquatic systems
(Novotny, V. and G. Chesters. 1989.
"Delivery of Sediment and Pollutants
from Nonpoint Sources: A Water
Quality Perspective." Journal of Soil
and Water Conservation, 44(6):568-76).
Estimates indicate that 80 percent of the
phosphorus and 73 percent of the
Kjeldahl nitrogen in streams is
associated with eroded sediment (U.S.
Department of Agriculture. 1989. "The
Second RCA Appraisal, Soil, Water and
Related Resources on Nonfederal Land
in the United States, Analysis of
Condition and Trends." Cited in
Fennessey, L.A.J., and A.R. Jarrett. 1994.
"The Dirt in a Hole: a Review of
Sedimentation Basins  for Urban Areas
and Construction Sites." Journal of Soil
and Water Conservation, 49(4):317-23).
  In watersheds experiencing intensive
construction activity, the localized
impacts of water quality may be severe
because of high pollutant loads,
primarily sediments. Siltation is the
largest cause of impaired water quality
in rivers and the third largest cause of
impaired water quality in lakes (U.S.
EPA, 1998). The 1996  305(b) report also
found that construction site discharges
were a source of pollution  in: 6 percent
of impaired rivers; 11 percent of
impaired lakes, ponds, and reservoirs;
and 11 percent of impaired estuaries.
Introduction of coarse sediment (coarse
sand or larger) or a large amount of fine
sediment is also a concern because of
the potential of rilling lakes and
reservoirs (along with  the associated
remediation costs for dredging), as well
as clogging stream channels (e.g.,
Paterson, R.G., M.I. Luger,  E.J. Burby,
E.J. Kaiser, H.R. Malcolm, and A.C.
Beard. 1993. "Costs and Benefits  of
Urban Erosion and Sediment Control:
North Carolina Experience."
Environmental Management 17(2):167-
78). Large inputs of coarse sediment into

-------
            Federal Register/Vol.  64, No. 235/Wednesday, December 8,  1999/Rules and Regulations    68729
  stream channels initially will reduce
  stream depth and minimize habitat
  complexity by filling in pools (U.S.
  EPA. 1991. Monitoring Guidelines to
  Evaluate Effects of Forestry Activities on
  Streams in the Pacific Northwest and
  Alaska. EPA 910/9-91-001. Seattle,
  WA). In addition, studies have shown
  that stream reaches affected by
  construction activities often extend well
  downstream of the construction site. For
  example, between 4.8 and 5.6
  kilometers of stream below construction
  sites in the Patuxent River watershed
  were observed to be impacted by
  sediment inputs (Fox, H.L. 1974.
  "Effects of Urbanization on the Patuxent
  River, with Special Emphasis on
  Sediment Transport, Storage, and
  Migration." Ph.D. dissertation. Johns
  Hopkins University, Baltimore, MD. As
  Cited in Klein, R.D. 1979. "Urbanization
  and Stream Quality Impairment." Water
  Resources Bulletin 15(4): 948-63).
   A primary concern at most
  construction sites is the erosion and
  transport process related to fine
 sediment because rain splash, rills (i.e.,
 a channel small enough to be removed
 by normal agricultural practices and
 typically less than 1-foot deep), and
 sheetwash encourage the detachment
 and transport of this material to
 waterbodies (Storm Water Quality Task
 Force. 1993. California Storm Water
 Best Management Practice Handbooks—
 Construction Activity. Oakland, CA:
 Blue Print Service). Construction sites
 also can generate other pollutants
 associated with onsite wastes, such as
 sanitary wastes or concrete truck
 washout.
   Although streams and rivers naturally
 carry sediment loads, erosion from
 construction sites and runoff from
 developed areas can elevate these loads
 to levels well above those in
 undisturbed watersheds. It is generally
 acknowledged that erosion rates from
 construction sites are much greater than
 from almost any other land use
 (Novotny, V. and H. Olem. 1994. Water
 Quality: Prevention, Identification, and
 Management of Diffuse Pollution. New
 York: Van Nostrand Reinhold). Results
 from both field studies and erosion
 models indicate that erosion rates from
 construction sites are typically an order
 of magnitude larger than row crops and
 several orders of magnitude greater than
 rates from well-vegetated areas, such as
 forests or pastures (USDA. 1970.
 "Controlling Erosion on Construction
 Sites." Agriculture Information Bulletin,
Washington, DC; Meyer, L.D., W.H.
Wischmeier, and W.H. Daniel. 1971.
"Erosion, Runoff and Revegetation of
Denuded Construction Sites."
Transactions of the ASAE 14(1):138-41;
  Owen, O.S. 1975. Natural Resource
  Conservation. New York: MacMillan. As
  cited in Paterson, et al., 1993).
    A recent review of the efficiency of
  sediment basins indicated that inflows
  from 12 construction sites had a mean
  TSS concentration of about 4,500 mg/L
  (Brown, W.E. 1997. "The Limits of
  Settling." Technical Note No. 83.
  Watershed Protection Techniques 2(3)).
  In Virginia, suspended sediment
  concentrations from housing
  construction sites were measured at
  500-3,000 mg/L, or about 40 times
  larger than the concentrations from
  already-developed urban areas (Kuo,
  C.Y. 1976. "Evaluation of Sediment
  Yields Due to Urban Development."
  Bulletin No. 98. Virginia Water
  Resources Research Center, Virginia
  Polytechnic Institute and State
  University, Blacksburg, VA).
   Similar impacts from storm water
 runoff have been reported in a number
  of other studies. For example, Daniel, et
 al., monitored three residential
 construction sites in southeastern
 Wisconsin and determined that annual
 sediment yields were more than 19
 times the yields from agricultural areas
 (Daniel, T.C., D. McGuire, D. Stoffel,
 and B. Miller. 1979. "Sediment and
 Nutrient Yield from Residential
 Construction Sites" Journal of
 Environmental Quality 8(3):304-08).
 Daniel, et al., identified total storm
 runoff, followed by peak storm runoff,
 as the most influential factors
 controlling the sediment loadings from
 residential construction sites. Daniel, et
 al., also found that suspended sediment
 concentrations were 15,000-20,000 mg/
 L in moderate events and up to 60,000
 mg/L in larger events.
  Wolman and Schick (Wolman,  M.G.
 and A.P. Schick. 1967. "Effects of
 Construction on Fluvial Sediment,
 Urban and Suburban Areas of
 Maryland."  Water Resources Research
 3(2): 451-64) studied the impacts of
 development on fluvial systems in
 Maryland and determined that sediment
 yields in areas undergoing construction
 were 1.5 to 75 times greater than
 detected in natural or agricultural
 catchments.  The authors summarize the
 potential impacts of construction  on
 sediment yields by stating that "the
 equivalent of many decades of natural
 or even agricultural erosion may take
 place during a single year from areas
 cleared for construction" (Wolman and
 Schick, 1967).
  A number of studies have examined
 the effects of road construction on
 erosion rates and sediment yields. A
highway construction project in West
Virginia disturbed only 4.2 percent of a
4.72-square-mile basin, but resulted in a
  three-fold increase in suspended
  sediment yields (Downs, S.C. and D.H.
  Appel. 1986. Progress Report on the
  Effects of Highway Construction on
  Suspended-Sediment Discharge in the
  Coal River and Trace Fork, West
  Virginia, 1975-81. USGS Water
  Resources Investigations Report 84-
  4275. Charlestown, WV). During the
  largest storm event, it was estimated
  that 80 percent of the sediment in the
  stream originated from the construction
  site. As is often the case, the increase in
  suspended sediment  load could not be
  detected further downstream, where the
  drainage area was more than 50 times
  larger (269 square miles).
   Another study evaluated the effect of
  290 acres of highway construction on
 watersheds ranging in size from 5 to 38
 square miles. Suspended sediment loads
 in the smallest watershed increased by
 250 percent, and the estimated sediment
 yield from the construction area was 37
 tons/acre during a 2-year period
 (Hainly, R.A. 1980. The Effects of
 Highway Construction on Sediment
 Discharge into Blockhouse Creek and
 Stream Valley Run, Pennsylvania. USGS
 Water Resources Investigations Report
 80-68. Harrisburg, PA). A more recent
 study in Hawaii showed that highway
 construction increased suspended
 sediment loads by 56  to 76 percent in
 three small (1 to 4 square mile) basins
 (Hill, B.R. 1996. Streamflow and
 Suspended-Sediment Loads Before and
 During Highway Construction, North
 Halawa, Haiku, and Kamooalii Drainage
 Basins, Oahu, Hawaii, 1983-91. USGS
 Water Resources Investigations Report
 96-4259. Honolulu, HI). A 1970 study
 determined that sediment yields from
 construction areas can be as much as
 500 times  the levels detected in rural
 areas (National Association of Counties
 Research Foundation.  1970. Urban Soil
 Erosion and Sediment Control. Water
 Pollution Control Research Series,
 Program #15030 DTL.  Federal Water
 Quality Administration, U.S.
 Department of Interior. Washington, DC)
  Yorke and Herb (Yorke, T.H., and W.J.
 Herb. 1978. Effects of  Urbanization on
 Streamflow and Sediment Transport in
 the Rock Creek and Anacostia River
 Basins, Montgomery County, Maryland,
 1962-74. USGS Professional Paper 1003,
 Washington, DC) evaluated nine
 subbasins in the Maryland portion of
 the Anacostia watershed for more than
 a decade in an effort to define the
 impacts of changing land use/land cover
 on sediment in runoff. Average annual
suspended sediment yields for
construction sites ranged from 7 to 100
tons/acre. Storm water discharges from
construction sites that  occur when the
land area is disturbed (and prior to

-------
68730    Federal  Register/Vol.  64,  No. 235/Wednesday, December 8, 1999/Rules and Regulations
surface stabilization) can significantly
impact designated uses. Examples of
designated uses include public water
supply, recreation, and propagation of
fish and wildlife. The siltation process
described previously can threaten all
three designated uses by (1} depositing
high concentrations of pollutants in
public water supplies; (2) decreasing the
depth of a waterbody, which can reduce
the volume of a reservoir or result in
limited use of a water body by boaters,
swimmers, and other recreational
enthusiasts; and (3) directly impairing
the habitat of fish and other aquatic
species, which can limit their ability to
reproduce.
  Excess sediment can cause a number
of other problems for waterbodies. It is
associated with increased turbidity and
reduced light penetration in the water
column, as well as more long-term
effects associated with habitat
destruction and increased difficulty in
filtering drinking water. Numerous
studies have examined the effect that
excess sediment has on aquatic
ecosystems. For example, sediment from
road construction activity in Northern
Virginia reduced aquatic insect and fish
communities by up to 85 percent and 40
percent, respectively (Reed, J.R. 1997.
"Stream Community Responses to Road
Construction Sediments." Bulletin No.
97.  Virginia Water Resources Research
Center, Virginia Polytechnic Institute,
Blacksburg, VA.  As cited in Klein, R.D.
1990. A Survey of Quality of Erosion
and Sediment Control and Storm Water
Management in the Chesapeake Bay
Watershed. Annapolis, MD: Chesapeake
Bay Foundation). Other studies have
shown that fine sediment (fine sand or
smaller) adversely affects aquatic
ecosystems by reducing  light
penetration, impeding sight-feeding,
smothering benthic organisms, abrading
gills and other sensitive  structures,
reducing habitat by clogging interstitial
spaces within a streambed, and
reducing the intergravel dissolved
oxygen by reducing the permeability of
the bed material  (Everest, F.H., J.C.
Beschta, K.V. Scrivener, J.R. Koski, J.R.
Sedell, and C.J. Cederholm. 1987. "Fine
Sediment and Salmonid Production: A
Paradox." Streamside Management:
Forestry and Fishery Interactions,
Contract No. 57, Institute of Forest
Resources, University of Washington,
Seattle, WA). For example, 4.8 and 5.6
kilometers  of stream below construction
sites in the Patuxent River watershed in
Maryland were found to have fine
sediment amounts 15 times greater than
normal (Fox, 1974. As cited in Klein,
1979). Benthic organisms in the
streambed can be smothered by
sediment deposits, causing changes in
aquatic flora and fauna, such as fish
species composition (Wolman and
Schick, 1967). In addition, the primary
cause of coral reef degradation in coastal
areas is attributed to land disturbances
and dredging activities due to urban
development (Rogers, C.S. 1990.
"Responses of Coral Reefs and Reef
Organizations to Sedimentation."
Marine Ecology Progress Series, 62:185-
202).
  EPA believes that the water quality
impact from small construction sites is
as high as or higher than the impact
from larger sites on a per acre basis. The
concentration of pollutants in the runoff
from smaller sites is similar to the
concentrations in the runoff from larger
sites. The proportion of sediment that
makes it from the construction site to
surface waters is likely the same for
larger and smaller construction sites in
urban areas because the runoff from
either site is usually delivered directly
to the storm drain network where there
is no opportunity for the sediment to be
filtered out.
  The expected contribution of total
sediment yields from small sites
depends, in part, on the extent to which
erosion and sedimentation controls are
being applied. Because current storm
water regulations are more likely to
require erosion and sedimentation
controls on larger sites in urban areas,
smaller construction sites that lack such
programs are likely to contribute a
disproportionate amount of the total
sediment from construction activities
(MacDonald, L.H. 1997. Technical
Justification for Regulating Construction
Sites 1—5 Acres in Size. Unpublished
report submitted to U.S. EPA,
Washington, DC).  Smaller construction
sites are less likely to have an effective
plan to control erosion and
sedimentation, are less likely to
properly  implement and maintain their
plans, and are less likely to be inspected
(Brown, W. and D. Caraco. 1997.
Controlling Storm Water Runoff
Discharges from Small Construction
Sites: A National Review. Submitted to
Office of Wastewater Management, U.S.
EPA, Washington, DC., by the Center for
Watershed Protection, Silver Spring,
MD). The proportion of sediment that
makes  it from the construction site to
surface waters is likely the same for
larger and smaller construction sites in
urban areas because the runoff from
either site is usually delivered directly
to the storm drain network, where there
is no opportunity for the sediment to be
filtered out.
  To confirm its belief that sediment
yields from small sites are as high as or
higher than the 20 to 150 tons/acre/year
measured from larger sites, EPA gave a
grant to the Dane County, Wisconsin
Land Conservation Department, in
cooperation with the USGS, to evaluate
sediment runoff from two small
construction sites. The first was a 0.34
acre residential lot and the second was
a 1.72 acre commercial office
development. Runoff from the sites was
channeled to a single discharge point for
monitoring.  Each site was monitored
before, during, and after construction.
  The Dane  County study found that
total solids concentrations from these
small sites are similar to total solids
concentrations from larger construction
sites. Results show that for both of the
study sites, total solids and suspended
solids concentrations were significantly
higher during construction than either
before or after construction. For
example, preconstruction total solids
concentrations averaged 642 mg/L
during the period when ryegrass was
established,  active construction total
solids concentrations averaged 2,788
mg/L, and post-construction total solids
concentrations averaged 132 mg/L (on a
pollutant load basis, this equaled 7.4 Ibs
preconstruction, 35 Ibs during
construction, and 0.6 Ibs post-
construction for total solids). While this
site was not properly stabilized before
construction, after construction was
complete and the site was stabilized,
post-construction concentrations were
more than 20 times less than during
construction. The results were even
more dramatic for the commercial site.
The commercial  site had one
preconstruction event, which resulted
in total solids concentrations of 138 mg/
L, while active construction averaged
more than 15,000 mg/L and post-
construction averaged only 200 mg/L
(on a pollutant load basis, this equaled
0.3 Ibs preconstruction, 490 Ibs during
construction, and 13.4 Ibs post-
construction for total solids). The active
construction period resulted in more
than 75 times more sediment than either
before or after construction (Owens,
D.W., P. Jopke, D.W. Hall, J. Balousek
and A. Roa. 1999. "Soil Erosion from
Small Construction Sites." Draft USGS
Fact Sheet. USGS and Dane County
Land Conservation Department, WI).
The total solids concentrations from
these small sites  in Wisconsin are
similar to total solids concentrations
from larger construction sites. For
example, a study evaluating the effects
of highway construction in West
Virginia found that a small storm
produced a sediment concentration of
7,520 mg/L (Downs and Appel, 1986).
  One important aspect of small
construction sites is the number of small
sites relative to larger construction sites

-------
                     Federal Register/Vol.  64, No. 235/Wednesday, December 8, 1999/Rules and Regulations    68731
          and total land area within the
          watershed. Brown and Caraco surveyed
          219 local jurisdictions to assess erosion
          and sediment control (ESC) programs.
          Seventy respondents provided data on
          the number of ESC permits for
          construction sites smaller than 5 acres.
          In 27 cases (38 percent of the
          respondents), more than three-quarters
          of the permits were for sites smaller
          than 5 acres; in another 18 cases (26
          percent), more than half of the permits
          were for sites smaller than 5 acres.
            In addition, data on the total acreage
          disturbed by smaller construction sites
          have been collected recently in two
          States (MacDonald, 1997). The most
          recent and complete data set is the
          listing of the disturbed area for each of
          the 3,831 construction sites permitted in
          North Carolina for 1994-1995 and
          1995-1996. Nearly 61 percent of the
          sites that were 1 acre or larger were
          between 1.0 and 4.9 acres in size. This
          proportion was consistent between
          years. Data showed that this range of
          sites accounted for 18 percent of the
          total area disturbed by construction. The
          values showed very little variation
          between the 2 years of data. The total
          disturbed area for all  sites over this 2-
          year period was nearly 33,000 acres, or
          about 0.1 percent of the total area of
          North Carolina.
            EPA estimates that construction sites
          disturbing greater than 5 acres disturb
          2.1-million acres of land (78.1 percent of
          the total) while sites disturbing between
          1 and 5 acres of land disturb 0.5-million
          acres of land (19.4 percent).  The
          remaining sites on less than 1 acres of
          land disturb 0.07-million acres of land
          (only 2.5 percent of the total). Given the
          high erosion rates associated with most
          construction sites, small construction
          sites can be a significant source of water
          quality impairment, particularly in
          small watersheds that are undergoing
          rapid development. Exempting sites
          under 1 acre will exclude only about 2.5
          percent of acreage from program
          coverage, but will exclude a far higher
          number of sites, approximately 25
          percent.
           Several studies have determined that
          the most effective construction runoff
          control programs rely on local plan
          review and field enforcement (Paterson,
          R. G. 1994. "Construction Practices: the
          Good, the Bad, and the Ugly."
          Watershed Protection Techniques 1(3)).
          In his review, Paterson suggests that,
          given the critical importance of field
          implementation of erosion and sediment
          control programs and  the apparent
          shortcomings that exist, much more
          focus should be given to plan
          implementation.
    Several commenters disputed the data
 presented in the proposed rule for storm.
 water discharges from smaller
. construction sites. One commenter
 stated that EPA has not adequately
 explained the basis for permitting
 construction activity down to 1
 disturbed acre. Another commenter
 stated that EPA did not present
 sufficient data on water quality impacts
 from construction sites disturbing less
 than 5 acres.
   EPA believes that the data presented
 above sufficiently support nationwide
 designation of storm water discharges
 from construction activity disturbing
 more than 1 acre. Based on total
 disturbed land area within a watershed,
 the cumulative effects of numerous
 small construction sites can have
 impacts similar to those of larger sites
 in a particular area. In addition, waivers
 for storm water discharges from smaller
 construction activity will exclude sites
 not expected to impair water quality.
 EPA will continue to collect water
 quality data on construction site storm
 water runoff.

 C. Statutory Background
   In 1972, Congress enacted the CWA to
 prohibit the discharge of any pollutant
 to waters of the United States from a
 point source unless the discharge is
 authorized by an NPDES permit.
 Congress added CWA section 402(p) in
 1987 to require implementation of a
 comprehensive program for addressing
 storm water discharges. Section
 402(p)(l) required EPA or NPDES-
 authonzed States or Tribes to issue
 NI'DES permits for the following five
 classes of storm water discharges
 composed entirely of storm water
 {"storm water discharges") specifically
 listed under section 402(p)(2):
   (A) a discharge subject to an NPDES
 permit before February 4, 1987
   (B) a discharge associated with
 industrial activity
   (C) a discharge from a municipal
 separate storm sewer system serving a
 population of 250,000 or more
   (D) a discharge from a municipal
 separate storm sewer system serving a
 population of 100,000 or more but less
 than 250,000
   (E) a discharge  that an NPDES
 permitting authority determines to be
 contributing to a violation of a water
 quality standard or a significant
 contributor of pollutants to the waters of
 the United States.
   Section 402(p)(3)(A) requires storm
 water discharges associated with
 industrial activity to meet all applicable
 provisions of section 402 and section
 301 of the CWA, including technology-
based requirements and any more;
 stringent requirements necessary to
 meet water quality standards. Section
 402(p)(3)(B) establishes NPDES permit
 standards for discharges from municipal
 separate storm sewer systems, or MS4s.
 NPDES permits for discharges from
 MS4s (1) may be issued on a system or
 jurisdiction-wide basis, (2) must include
 a requirement to effectively prohibit
 non-storm water discharges into the
 storm sewers, and (3) must require
 controls to reduce pollutant discharges
 to the maximum extent practicable,
 including best management practices,
 and other provisions as the
 Administrator or the States determine to
 be appropriate for the control of such
 pollutants. At this time, EPA determines
 that water quality-based controls,
 implemented through the iterative
 processes described today are
 appropriate for the control of such
 pollutants and will result in reasonable
 further progress towards attainment of
 water quality standards. See sections
 ILL and II.H.3 of the preamble.
  In CWA section  402(p)(4), Congress
 established statutory deadlines for the
 initial steps in implementing the NPDES
 program for storm  water discharges.
 This section required development of
 NPDES permit application regulations,
 submission of NPDES permit
 applications, issuance of NPDES
 permits for sources identified in section
 402(p)(2), and compliance with NPDES
 permit conditions. In addition, this
 section required industrial facilities and
 large MS4s to submit NPDES permit
 applications for storm water discharges
 by February 4, 1990. Medium MS4s
 were to submit NPDES permit
 applications by February 4, 1992. EPA
 and authorized NPDES  States were
 prohibited from requiring an NPDES
 permit for any other storm water
 discharges until October 1,1994.
  Section 402(p)(5) required EPA to
 conduct certain studies and submit a
 report to Congress. This requirement is
 discussed in the following section.
  Section 402(p)(6) requires EPA, in
 consultation with States and local
 officials, to issue regulations for the
 designation of additional storm water
 discharges to be regulated to protect
water quality. It also requires EPA to
extend the existing storm water program
to regulate newly designated sources. At
a minimum, the extension must
establish (1) priorities, (2) requirements
for State storm water management
programs, and (3) expeditious
deadlines. Section  402(p)(6) specifies
that the program may include
performance standards, guidelines,
guidance, and management practices
and treatment requirements, as

  appropriate. Today's rule implements
  this section.

  D. EPA's Reports to Congress
   Under CWA section 402(p)(5), EPA, in
  consultation with the States, was
  required to conduct a study. The study
  was to identify unregulated sources of
  storm water discharges, determine the
  nature and extent of pollutants in  such
  discharges, and establish procedures
  and methods to mitigate the impacts of
  such discharges on water quality.
  Section 402(p)(5) also required EPA to
  report the results of the first two
  components of that study to Congress by
  October 1,1988, and the final report by
  October 1, 1989.
   In March 1995, EPA submitted to
 Congress a report that reviewed and
 analyzed the nature of storm water
 discharges from municipal and
 industrialacilities that were not already
 regulated under the  initial NPDES
 regulations for storm water (U.S.
 Environmental Protection Agency,
 Office of Water. 1995. Storm Water
 Discharges Potentially Addressed by
 Phase II of the National Pollutant
 Discharge Elimination System Storm
 Water Program: Report to Congress.
 Washington, D.C. EPA 833-K-94-002)
 ("Report"). The Report also  analyzed
 associated pollutant loadings and water
 quality impacts from these unregulated
 sources. Based on identification of
 unregulated municipal sources and
 analysis of information on impacts of
 storm water discharges from municipal
 sources, the Report recommended that
 the NPDES program for storm water
 focus on the 405 "urbanized areas"
 identified by the Bureau of the Census.
 The Report further found that a number
 of discharges from unregulated
 industrial facilities warranted further
 investigation to determine the need for
 regulation. It classified these
 unregulated industrial discharges in two
 groups: Group A and Group B. Group A
 comprised sources that may  be
 considered a high priority for inclusion
 in the NPDES program for storm water
 because discharges from these sources
 are similar or identical to already
 regulated sources. These "look alike"
 storm water discharge sources were not
 covered in the initial NPDES regulations
 for storm water due to the language used
 to define "associated with industrial
 activity." In the initial regulations for
 storm water, "industrial activity" is
 identified using Standard Industrial
 Classification (SIC) codes. The use of
 SIC codes led to incomplete
 categorization of industrial activities
with discharges that needed to be
regulated to protect water quality.
Group B consisted of 18 industrial
 sectors, which included sources that
 EPA expected to contribute to storm
 water contamination due to the
 activities conducted and pollutants
 anticipated onsite (e.g., vehicle
 maintenance, machinery and electrical
 repair, and intensive agricultural
 activities).
   EPA reported on the latter component
 of the section 402(p)(5) study via
 President Clinton's Clean Water
 Initiative, which was released on
 February 1, 1994 (U.S. Environmental
 Protection Agency, Office of Water.
 1994. President Clinton's Clean Water
 Initiative. Washington, D.C. EPA 800-R—
 94-001) ("Initiative"). The Initiative
 addressed a number of issues associated
 with NPDES requirements for storm
 water discharges and proposed (1)
 establishing a phased compliance with
 a water quality standards approach for
 discharges from municipal separate
 storm sewer systems with priority on
 controlling discharges from municipal
 growth and development areas, (2)
 clarifying that the maximum extent
 practicable standard should be applied
 in a site-specific, flexible manner, taking
 into account cost considerations as well
 as water quality effects, (3) providing an
 exemption from the NPDES program for
 storm water discharges from industrial
 facilities with no activities or significant
 materials exposed to storm water, (4)
 providing extensions to the statutory
 deadlines to complete implementation
 of the NPDES program for the storm
 water program, (5) targeting urbanized
 areas for the requirements in the NPDES
 program for storm water, and (6)
 providing control of discharges from
 inactive and abandoned mines  located
 on Federal lands in a more targeted,
 flexible manner. Additionally, prior to
 promulgation of today's rule, section
 431 of the Agency's Appropriation Act
 for FY 2000 (Departments of Veterans
 Affairs and Housing and Urban
 Development and Independent Agencies
 Appropriations Act of 2000, Public Law
 106-74, section 432  (1999))  directed
 EPA to report on certain matters to be
 covered in today's rule. That report
 supplements the study required by
 CWA Section 402(p)(5). EPA is
 publishing the availability of that report
 elsewhere in this issue of the Federal
 Register.
  Several commenters asserted that the
Report to Congress is an inadequate
basis for the designation and regulation
 of sources covered under today's final
rule, specifically the nationwide
 designation of small municipal  separate
storm sewer systems within urbanized
areas and construction activities
disturbing between one and five acres.
   EPA believes that it has developed an
  adequate record for today's regulation
  both through the Report to Congress and
  the Clean Water Initiative and through
  more recent activities, including the
  FACA Subcommittee process, regulatory
  notices and evaluation of comments,
  and recent research and analysis. EPA
  does not interpret the congressional
  reporting requirements of CWA section
  402(p)(5) to be the sole basis for
  determining sources to be regulated
  under today's final rule.
   EPA's  decision to designate on a
  national  basis small MS4s in urbanized
  areas  is supported by studies that
  clearly show a direct correlation
  between  urbanization and adverse water
  quality impacts from  storm water
  discharges. (Schueler, T. 1987.
  Controlling Urban Runoff: A Practical
 Manual for Planning » Designing Urban
 BMPs. Metropolitan Washington
 Council of Governments). "Urbanized
 areas"—within which all small MS4s
 would be covered—represent the most
 intensely developed and dense areas of
 the Nation. They constitute only two
 percent of the land area but 63 percent
 of the total  population. See section I.B.I,
 Urban Development, above, for studies
 and assessments of the link between
 urban development and storm water
 impacts on  water resources.
   Commenters argued that the Report to
 Congress  does not address storm water
 discharges from construction sites. They
 further argued that the designation of
 small construction sites per today's final
 rule goes  beyond the President's 1994
 Initiative  because the Initiative only
 recommends requiring municipalities to
 implement a storm water management
 program to control unregulated storm
 water sources, "including discharges
 from construction of less than 5 acres,
 which are part of growth, development
 and significant redevelopment
 activities." They point out that the
 Initiative  provides that unregulated
 storm water discharges not addressed
 through a municipal program would not
 be covered by the NPDES program.
 Commenters assert that EPA has not
 developed a record independent of its
 section 402(p)(5) studies that
 demonstrates the necessity of regulating
 under a separate NPDES permit storm
 water discharges from smaller
 construction sites "to protect water
 quality." EPA disagrees.
  EPA evaluated the nature and extent
 of pollutants from construction site
 sources in a process that was separate
 and distinct from the development of
the Report to Congress. Today's decision
to regulate certain storm water
 discharges from construction sites
 disturbing less than 5 acres arose in part

                     Federal Register/Vol. 64, No.  235/Wednesday,  December 8, 1999/Rules and  Regulations    68733
          out of the 9th Circuit remand in NRDC
          v. EPA, 966 F.2d 1292 (9th Cir. 1992].
          In that case, the court remanded
          portions of the Phase I storm water
          regulations related to discharges from
          construction sites. Those regulations
          define "storm water discharges
          associated with industrial activity" to
          include only those storm water
          discharges from construction sites
          disturbing 5 acres or more of total land
          area (see 40 CFR 122.26(b)(14)(x)). In its
          decision, the court concluded that the 5-
          acre threshold was improper because
          the Agency had failed to identify
          information "to support its perception
          that construction activities on less than
          5 acres are non-industrial in nature"
          (966 F.2d at 1306). The court remanded
          the below 5 acre exemption to EPA for
          further proceedings (966 F.2d at 1310).
            In a Federal Register notice issued on
          December 18,1992, EPA noted that it
          did not believe that the Court's decision
          had the effect of automatically
          subjecting small construction sites to
          the existing application requirements
          and deadlines. EPA believed that
          additional notice and comment were
          necessary to clarify the status of these
          sites. The information received during
          the notice and comment process and
          additional research, as discussed in
          section I.B.3 Construction Site Runoff,
          formed the basis for the designation of
          construction activity disturbing between
          one and five acres on a nationwide
          basis. EPA's objectives in today's
          proposal include an effort to (1) address
          the 9th  Circuit remand, (2) address
          water quality concerns associated with
          construction activities that disturb less
          than 5 acres of land, and (3) balance
          conflicting recommendations and
          concerns of stakeholders.
            One commenter noted that EPA's
          proposal would fail to regulate
          industrial facilities identified as Group
          A and Group B in the March 1995
          Report to Congress. EPA is relying on
          the analysis in the Report, which
          provided that the recommendation for
          coverage was meant as guidance and
          was not intended to be an identification
          of specific categories that must be
          regulated under Section 402(p)(6).
          Report to Congress, p. 4-1. The Report
          recognized the existence of limited data
          on which to base loadings estimates to
          support the nationwide designation of
          individual or categories of sources.
          Report to Congress, p. 4-44.
          Furthermore, during FACA
          Subcommittee discussion, EPA
          continued to urge stakeholders to
         provide further data relating to
          industrial  and commercial storm water
         sources, which EPA did not receive.
         EPA concluded that, due to  insufficient
 data, these sources were not appropriate
 for nationwide designation at this time.

 E. Industrial Facilities Owned or
 Operated by Small Municipalities
   Congress granted extensions to the
 NPDES permit application process for
 selected classes of storm water
 discharges associated with industrial
 activity. On December 18,1991,
 Congress enacted the Intermodal
 Surface Transportation Efficiency Act
 (ISTEA), which postponed NPDES
 permit application deadlines for most
 storm water discharges associated with
 industrial activity at facilities that are
 owned or operated by small
 municipalities. EPA and States
 authorized to administer the NPDES
 program could not require any
 municipality with a population of less
 than 100,000 to apply for or obtain an
 NPDES permit for any storm water
 discharge associated with industrial
 activity prior to October 1,1992, except
 for storm water discharges from airports,
 power plants, or uncontrolled sanitary
 landfills. See 40 CFR 122.26(e)(l); 57 FR
 11524, April 2, 1992 (reservation of
 NPDES application deadlines for ISTEA
 facilities].
  The facilities exempted by ISTEA
 discharge storm water in the same
 manner (and are expected to use
 identical processes and materials) as the
 industrial facilities regulated under the
 1990 Phase I regulations. Accordingly,
 these facilities pose similar water
 quality problems. The extended
 moratorium for these facilities was
 necessary to allow municipalities
 additional time to comply with NPDES
 requirements. The proposal for today's
 rule  would have maintained the existing
 deadline for seeking coverage under an
 NPDES permit (August 7, 2001).
  Today's rule changes the permit
 application deadline for such
 municipally owned or operated
 facilities discharging industrial storm
 water to make it consistent with the
 application date for small regulated
 MS4s. Because EPA missed its March
 1999 deadline for promulgating today's
 rule, and the deadline for MS4s to
 submit permit applications has been
 extended to three years and 90 days
 from the date of this notice, the deadline
 for permitting ISTEA sources has been
 similarly extended. The permitting of
these sources is discussed below in
 section "II.I.3. ISTEA Sources."

F. Related Nonpoint Source Programs
  Today's rule addresses point source
 discharges of storm water runoff and
non-storm water discharges into MS4s.
Many of these sources have been
addressed by nonpoint source control
 programs, which are described briefly
 below.
   In 1987, section 319 was added to the
 CWA to provide a framework for
 funding State and local efforts to
 address pollutants from nonpoint
 sources not addressed by the NPDES
 program.  To obtain funding, States are
 required to submit Nonpoint Source
 Assessment Reports identifying State
 waters that, without additional control
 of nonpoint sources of pollution, could
 not reasonably be expected to attain or
 maintain  applicable water quality
 standards or other goals and
 requirements of the CWA. States are
 also required to prepare and submit for
 EPA approval a statewide Nonpoint
 Source Management Program for
 controlling nonpoint source water
 pollution to navigable waters within the
 State and improving the quality of such
 waters. State program submittals must
 identify specific best management
 practices  (BMPs) and measures that the
 State proposes to  implement in the first
 four years after program submission to
 reduce pollutant loadings from
 identified nonpoint sources to levels
 required to achieve the stated water
 quality objectives.
   State nonpoint source programs
 funded under section  319 can include
 both regulatory and nonregulatory State
 and local  approaches. Section
 319(b)(2)(B) specifies that a combination
 of "nonregulatory or regulatory
 programs  for enforcement, technical
 assistance, financial assistance,
 education, training, technology transfer,
 and demonstration projects' may be
 used, as necessary, to achieve
 implementation of the BMPs or
 measures  identified in the section  319
 submittals.
  Section 6217 of the Coastal Zone Act
 Reauthorization Amendments (CZARA)
 of 1990 provides that States with
 approved  coastal zone management
 programs  must develop coastal
 nonpoint pollution control programs
 and submit them to EPA and the
 National Oceanic and Atmospheric
 Administration (NOAA)  for approval.
 Failure to  submit an approvable
 program will result in  a reduction of
 Federal grants under both the Coastal
 Zone Management Act and section 319
 of the CWA.
  State coastal nonpoint pollution
 control programs under CZARA must
 include enforceable policies and
 mechanisms that ensure
 implementation of the management
measures throughout the coastal
management area. EPA issued Guidance
Specifying Management Measures for
Sources of Nonpoint Pollution in
 Coastal Waters under section 6217(g) in
_

-------
 68734    Federal Register/Vol.  64, No. 235/Wednesday, December 8,  1999/Rules  and Regulations
 January 1993. The guidance identifies
 management measures for five major
 categories of nonpoint source pollution.
 The management measures reflect the  •
 greatest degree of pollutant reduction
 that is economically achievable for each
 of the listed sources. These management
 measures provide reference standards
 for the States to use in developing or
 refining their coastal nonpoint
 programs. A few management measures,
 however, contain quantitative standards
 that specify pollutant  loading
 reductions. For example, the New
 Development Management Measure,
 which is applicable to construction in
 urban areas, requires (1) that by design
 or performance the average annual total
 suspended solid loadings be reduced by
 80 percent and (2) to the extent
 practicable, that the pre-development
 peak runoff rate and average volume be
 maintained.
  EPA and NOAA published Coastal
 Nonpoint Pollution Control Program:
 Program Development and Approval
 Guidance (1993]. The  document
 clarifies that States generally must
 implement management measures for
 each source category identified in the
 EPA guidance developed under section
 6217(g). Coastal Nonpoint Pollution
 Control Programs are not required to
 address sources that are clearly
 regulated under the NPDES program as
 point source discharges. Specifically,
 such programs would  not need to
 address small MS4s and construction
 sites covered under NPDES storm water
 permits (both general and individual).
II. Description of Program
A. Overview
 1. Objectives EPA Seeks To Achieve in
Today's Rule
  EPA seeks to achieve several
objectives in today's final rule. First,
 EPA is implementing the requirement
 under CWA section 402(p)(6) to provide
 a comprehensive storm water program
 that designates and controls additional
 sources of storm water discharges to
 protect water quality. Second, EPA is
 addressing storm water discharges from
 the activities exempted under the 1990
 storm water permit application
 regulations that were remanded by the
 Ninth Circuit Court of Appeals in NRDC
 v. EPA, 966 F.2d 1292 (9th Circuit,
 1992). These are construction activities
 disturbing less than 5 acres and so-
 called "light" industrial activities not
 exposed to storm water (see discussion
 of "no exposure" below). Third, EPA is
 providing coverage for the so-called
 "donut holes" created by the existing
 NPDES storm water program. Donut
 holes are geographic gaps in the NPDES
 storm water program's regulatory
 scheme. They are MS4s located within
 areas covered by the existing NPDES
 storm water program, but not currently
 addressed by the storm water program
 because it is based  on political
 jurisdictions. Finally, EPA also is trying
 to promote watershed planning as a
 framework for implementing water
 quality programs where possible.
  Although EPA had options for
 different approaches (see alternatives
 discussed in the January 9,1998,
 proposed regulation), EPA believes it
 can best achieve its objectives through
 flexible innovations within the
 framework of the NPDES program.
 Unlike the interim  section 402(p)(6)
 storm water regulations EPA
 promulgated in 1995, EPA no longer
 designates all of the unregulated storm
 water discharges for nationwide
coverage under the NPDES program for
storm water. The framework for today's
 final rule is one that balances automatic
designation on a nationwide basis and
 locally-based designation and waivers.
 Nationwide designation applies to those
 classes or categories of storm water
 discharges that EPA believes present a
 high likelihood of having adverse water
 quality impacts, regardless of location.
 Specifically, today's rule designates
 discharges from small MS4s located in
 urbanized areas and storm water
 discharges from construction activities
 that result in land disturbance equal to
 or greater than one and less than five
 acres. As noted under Section I.E.,
 Water Quality Concerns/Environmental
 Impact Studies  and Assessments, these
 two categories of storm water sources,
 when unregulated, tend to cause
 significant adverse water quality
 impacts. Additional sources are not
 covered on a nationwide basis either
 because EPA currently lacks
 information indicating a consistent
 potential for adverse water quality
 impact or because EPA believes that the
 likelihood of adverse impacts on water
 quality is low, with some localized
 exceptions. Additional individual
 sources or categories of storm water
 discharges could, however, be covered
 under the program through a local
 designation process. A permitting
 authority may designate additional
 small MS4s after developing designation
 criteria and applying those criteria to
 small MS4s located  outside of an
 urbanized area,  in particular those with
a population of 10,000 or more and a
population density of at least 1,000.
Exhibit 1 illustrates  the designation
framework for today's final rule.

          population of at least 10,000 and a population

BILLING CODE 6560-50-C

-------
68736    Federal  Register/Vol.  64,  No. 235/Wednesday, December 8, 1999/Rules and  Regulations
   The designation framework for
 today's final rule provides a significant
 degree of flexibility. The proposed
 provisions for nationwide designation of
 storm water discharges from
 construction and from small MS4s in
 urbanized areas allowed for a waiver of
 applicable requirements based on
 appropriate water quality conditions.
 Today's final rule expands and
 simplifies those waivers.
   The permitting authority may waive
 the requirement for a permit for any
 small MS4 serving a jurisdiction with a
 population of less than 1,000 unless
 storm water controls are needed because
 the MS4 is contributing to a water
 quality impairment. The permitting
 authority may also waive permit
 coverage for MS4s  serving a jurisdiction
 with a population of less than 10,000 if
 all waters that receive a discharge from
 the MS4 have been evaluated and
 discharges from the MS4 do not
 significantly contribute to a water
 quality impairment or have the potential
 to cause an impairment. Today's rule
 also allows States with a watershed
 permitting approach to phase in
 coverage for MS4s  in jurisdictions with
 populations under 10,000.
  Water quality conditions are also the
 basis for a waiver of requirements for
 storm water discharges from
 construction activities disturbing
 between one and five acres. For these
 small construction sources, the rule
 provides significant flexibility  for
 waiving otherwise  applicable regulatory
 requirements where a permitting
 authority determines, based on water
 quality and watershed considerations,
 that storm water discharge controls are
 not needed.
  Coverage can be extended to
 municipal and construction sources
 outside the nationwide designated
 classes or categories based on watershed
 and case-by-case assessments. For the
 municipal storm water program, today's
 rule provides broad discretion to NPDES
 permitting authorities to develop and
 implement criteria  for designating storm
 water discharges from small MS4s
 outside of urbanized areas. Other storm
 water discharges from unregulated
 industrial, commercial, and residential
 sources will not be subject to the NPDES
 permit requirements unless a permitting
 authority determines on a case-by-case
basis (or on a categorical basis within
 identified geographic areas such as a
 State or watershed) that regulatory
 controls are needed to protect water
quality. EPA believes that the flexibility
provided in today's rule facilitates
watershed planning.
 2. General Requirements for Regulated
 Entities Under Today's Rule
   As previously noted, today's final rule
 defines additional classes and categories
 of storm water discharges for coverage
 under the NPDES program. These
 designated dischargers are required to
 seek coverage under an NPDES permit.
 Furthermore, all NPDES-authorized
 States and Tribes  are required to
 implement these provisions and make
 any necessary amendments to current
 State and Tribal NPDES regulations to
 ensure consistency with today's final
 rule. EPA remains the NPDES
 permitting authority for jurisdictions
 without NPDES authorization.
   Today's final rule includes some new
 requirements for NPDES permitting
 authorities implementing the CWA
 section 402(p)(6) program. EPA has
 made a significant effort to build
 flexibility into the program while
 attempting to maintain an appropriate
 level of national consistency. Permitting
 authorities must ensure that NPDES
 permits issued to MS4s include the
 minimum control measures established
 under the program. Permitting
 authorities also have the ability to make
 numerous decisions including who is
 regulated under the program, i.e., case-
 by-case designations and waivers, and
 how responsibilities should be allocated
 between regulated entities.
  Today's final rule extends the NPDES
 program to include discharges from  the
 following: small MS4s within urbanized
 areas (with the exception of systems
 waived from the requirements by the
 NPDES permitting authority); other
 small MS4s meeting designation criteria
 to be established by the permitting
 authority; and any remaining MS4 that
 contributes substantially to the storm
 water pollutant loadings of a physically
 interconnected MS4 already subject to
 regulation under the NPDES program.
 Small MS4s include urban storm sewer
 systems owned by Tribes, States,
political subdivisions of States, as well
 as the United States, and other systems
 located within an  urbanized area that
 fall within the definition of an MS4.
These include, for example, State
 departments of transportation (DOTs),
public universities, and federal military
bases.
  Today's final rule requires all
regulated small MS4s to develop and
implement a storm water management
program. Program components include,
at a minimum, 6 minimum measures to
address: public education and outreach;
public involvement; illicit discharge
detection and elimination; construction
site runoff control; post-construction
storm water management in new
 development and redevelopment; and
 pollution prevention and good
 housekeeping of municipal operations.
 These program components will be
 implemented through NPDES permits.
 A regulated small MS4 is required to
 submit to the NPDES permitting
 authority, either in its notice of intent
 (NOI) or individual permit application,
 the BMPs to be implemented and the
 measurable goals for each of the
 minimum control measures listed
 above.
   The rule addresses all storm water
 discharges from construction site
 activities involving clearing, grading
 and excavating land equal to or greater
 than 1 acre and less than 5 acres, unless
 requirements are otherwise waived by
 the NPDES permitting authority.
 Discharges from such sites, as well as
 construction sites disturbing less than 1
 acre of land that are designated by the
 permitting authority, are required to
 implement requirements set forth in the
 NPDES permit, which may reference the
 requirements of a qualifying local
 program issued to cover such
 discharges.
   The rule also addresses certain other
 sources regulated under the existing
 NPDES program for storm water. For
 municipally-owned industrial sources
 required to be regulated under the
 existing NPDES storm water program
 but exempted from immediate
 compliance by the Intermodal Surface
 Transportation Act of 1991 (ISTEA), the
 rule revises the existing deadline for
 seeking coverage under an NPDES
 permit (August 7, 2001) to make it
 consistent with the application date for
 small regulated MS4s. (See section 1.3.
 below.) The rule also provides relief
 from NPDES storm water permitting
 requirements for industrial sources with
 no exposure of industrial materials and
 activities to storm water.
 3. Integration of Today's Rule With the
Existing Storm Water Program

  In developing an approach for today's
 final rule, numerous early interested
stakeholders encouraged EPA to seek
 opportunities to integrate, where
possible, the proposed Phase II
requirements with existing Phase I
requirements, thus facilitating a unified
storm water discharge  control program.
EPA believes that this objective is met
by using the NPDES framework. This
framework  is already applied to
regulated storm water discharge sources
and is extended to those sources
 designated under today's rule. This
approach facilitates program
consistency, public access to
information, and program oversight.

-------
           Federal Register/Vol. 64, No. 235/Wednesday, December 8,  1999/Rules and Regulations    68737
   EPA believes that today's final rule
 provides consistency in terms of
 program coverage and requirements for
 existing and newly designated sources.
 For example, the rule includes most of
 the municipal donut holes, those MS4s
 located in incorporated places,
 townships or towns with a population
 under 100,000 that are within Phase I
 counties. These MS4s are not addressed
 by the existing NPDES storm water
 program while MS4s in the surrounding
 county are currently addressed. In
 addition, the minimum control
 measures required in today's rule for
 regulated small MS4s are very similar to
 a number of the permit requirements for
 medium and large MS4s under the
 existing storm water program. Following
 today's rule, permit requirements for all
 regulated MS4s (both those under the
 existing program and those under
 today's rule) will require
 implementation of BMPs. Furthermore,
 with regard to the development of
 NPDES permits to protect water quality,
 EPA intends to apply the August 1,
 1996, Interim Permitting Approach for
 Water Quality-Based Effluent
 Limitations in Storm Water Permits
 (hereinafter, "Interim Permitting
 Approach") (see Section II.L.l. for
 further description) to all MS4s covered
 by the NPDES program.
  EPA is applying NPDES permit
 requirements to construction sites below
 5 acres that are similar  to the existing
 requirements for those above 5 acres
 and above. In addition, today's rule
 allows compliance with qualifying
 local, Tribal, or State erosion and
 sediment controls to meet the erosion
 and sediment control requirements of
 the general permits for storm water
 discharges associated with construction.
 both above and below 5 acres.
 4. General Permits
  EPA recommends using general
 permits for all newly regulated storm
 water sources under today's rule. The
 use of general permits, instead of
 individual permits, reduces the
 administrative burden on permitting
 authorities, while also limiting the
 paperwork burden on regulated parties
 seeking permit authorization. Permitting
 authorities may, of course, require
 individual permits in some cases to
 address specific concerns, including
permit non-compliance.
  EPA recommends that general permits
 for MS4s, in particular, be issued on a
watershed basis, but recognizes that
 each permitting authority must decide
how to develop its general permit(s).
Permit conditions developed to address
concerns and conditions of a specific
watershed could reflect a watershed
 plan; such permit conditions must
 provide for attainment of applicable
 water quality standards (including
 designated uses), allocations of
 pollutant loads established by a TMDL,
 and timing requirements for
 implementation of a TMDL. If the
 permitting authority issues a State-wide
 general permit, the permitting authority
 may include separate conditions
 tailored to individual watersheds or
 urbanized areas. Of course, for a newly
 regulated MS4, modification of an
 existing individual MS4 permit to
 include the newly regulated MS4 as a
 "limited co-permittee" also remains an
 option.

 5. Tool Box
   During the FACA process, many
 Storm Water Phase II FACA
 Subcommittee representatives expressed
 an interest, which was endorsed by the
 full Committee, in having EPA develop
 a "tool box" to assist States, Tribes,
 municipalities, and other parties
 involved in the Phase II program. EPA
 made a commitment to work with Storm
 Water Phase II FACA Subcommittee
 representatives in developing such a
 tool  box. with the expectation that a tool
 box would facilitate implementation of
 the storm water program in an effective
 and cost-efficient manner. EPA has
 developed a preliminary working tool
 box (available on EPA's web page at
 w\vw.epa.gov/owm/sw/toolbox). EPA
 intends to have the tool box fully
 developed by the time of the first
 general permits. EPA also intends to
 update the tool box as resources and
 data  become available. The tool box will
 include the following eight main
 components: fact sheets; guidances; a
 menu of BMPs for the six MS4
 minimum measures; an information
 clearinghouse; training and outreach
 efforts; technical research; support for
 demonstration projects; and compliance
 monitoring/assistance tools. EPA
 intends to issue the menu of BMPs, both
 structural and non-structural, by
 October 2000. In addition, EPA will
 issue by October 2000 a "model" permit
 and will issue by October 2001 guidance
 materials on the development of
 measurable goals for municipal
programs.
  In  an attempt to avoid duplication,
the Agency has undertaken an effort to
 identify and coordinate sources of
information that relate to the storm
water discharge control program from
both  inside and outside the Agency.
Such information includes research and
 demonstration projects, grants, storm
water management-related programs,
and compendiums of available
documents, including guidances, related
 directly or indirectly to the
 comprehensive NPDES storm water
 program. Based on this effort, EPA is
 developing a tool box containing fact
 sheets and guidance documents
 pertaining to the overall program and
 rule requirements (e.g., guidance on
 municipal and construction programs,
 and permitting authority guidance on
 designation and waiver criteria); models
 of current programs aimed at assisting
 States, Tribes, municipalities, and
 others in establishing  programs; a
 comprehensive list of reference
 documents organized  according to
 subject area (e.g.,  illicit discharges,
 watersheds, water quality standards
 attainment, funding sources, and similar
 types of references); educational
 materials; technical research data; and
 demonstration project results. The
 information collected  by EPA  will not
 only provide  the background for tool
 box materials, but will also be made
 available through an information
 clearinghouse on the world wide web.
   With assistance from EPA, the
 American Public Works Association
 (APWA) developed a workbook and
 series of workshops on the proposed
 Phase II rule.  Ten workshops were held
 from September 1998 through May
 1999. Depending on available  funding,
 these workshops may  continue after
 publication of today's  final rule. EPA
 also intends to provide training to
 enable regional offices to educate States,
 Tribes, and municipalities about the
 storm water program and the
 availability of the tool  box materials.
   The CWA currently  provides funding
 mechanisms to support activities related
 to storm water. These mechanisms will
 be described in the tool box. Activities
 funded under grant and loan programs,
 which could be used to assist in storm
 water program development, include
 programs in the nonpoint source area,
 storm water demonstration projects,
 source water protection and wastewater
 construction projects. EPA has already
 provided funding  for numerous research
 efforts in these areas, including a
 database of BMP effectiveness  studies
 (described below), an assessment of
technologies for storm water
management,  a study of the
effectiveness of storm water BMPs for
controlling the impacts of watershed
imperviousness, protocols for wet
weather monitoring, development of a
dynamic model for wet weather flows,
and numerous outreach projects.
  EPA has entered into a cooperative
agreement with the Urban Water
Resources Research Council of the
American Society of Civil Engineers
(ASCE) to develop a scientifically-based
management tool for the information

-------
 66738     Federal  Register/Vol. 64. No. 235/Wednesday, December 8, 1999/Rules and Regulations
 needed to evaluate the effectiveness of
 urban storm water runoff BMPs
 nationwide. The long-term goal of the
 National Stormwater BMP Database
 project is to promote technical design
 improvements for BMPs and to better
 match their selection and design to  the
 local storm water problems being
 addressed. The project team has
 collected and evaluated hundreds of
 existing published BMP performance
 studies and created a database covering
 about 75 test sites. The database
 includes detailed information on the
 design of each BMP and its watershed
 characteristics, as well as its
 performance. Eventually the database
 will include the nationwide collection
 of information on the characteristics of
 structural and non-structural BMPs,
 data collection efforts (e.g., sampling
 and flow gaging equipment),
 climatological characteristics, watershed
 characteristics, hydrologic data, and
 constituent data. The database will
 continue to grow as new BMP data
 become available. The initial release of
 the database, which includes data entry
 and retrieval software, is available on
 CD-ROM and operates on Windows®-
 compatible personal computers. The
 ASCE project team envisions that
 periodic updates to the database will be
 distributed through the Internet. The
 team is currently developing a system
 for Internet retrieval of selected database
 records, and this system is expected to
 be available in early 2000.
   EPA and ASCE invite BMP designers,
 owners and operators to participate in
 the continuing database development
 effort. To make this effort successful, a
 large database is essential. Interested
 persons are encouraged to submit their
 BMP performance evaluation data and
 associated BMP watershed
 characteristics  for potential entry into
 the database. The software included in
 the CD-ROM allows data providers to
 enter their BMP data locally, retain and
 edit the data as needed, and submit
 them to the ASCE Database
 Clearinghouse when ready.
   To obtain a copy of the database,
 please contact Jane Clary, Database

   In addition, EPA requests that
 researchers planning to conduct BMP
 performance evaluations compile and
 collect BMP reporting information
 according to the standard format
 developed by ASCE. The format is
 provided with the database software and
 is also available on the ASCE website at
 www.asce.org/peta/tech/nsbd01.html.

B. Readable Regulations
  Today, EPA is finalizing new
regulations in a "readable regulation"
format. This reader-friendly, plain
language approach is a departure from
traditional regulatory language and
should enhance the rule's readability.
These plain language regulations use
questions and answers, "you" to
identify the person who must comply,
and terms like "must" rather than
"shall" to identify a mandate. This new
format, which minimizes layers of
subparagraphs, should also allow the
reader to easily locate specific
provisions of the regulation.
  Some sections of today's final rule are
presented in the traditional language
and format because these sections
amend existing regulations. The
readable regulation format was not used
in these existing provisions in an
attempt to avoid confusion or disruption

-------
           Federal Register/Vol. 64, No.  235/Wednesday, December 8, 1999/Rules and Regulations    68739
 of the readability of the existing
 regulations.
   Most commenters supported EPA's
 use of plain language and agreed with
 EPA that the question and answer
 format makes the rule easier to
 understand. Three commenters thought
 that EPA should retain the traditional
 rule format. The June 1,1998,
 Presidential memorandum directs all
 government agencies to write
 documents in plain language. Based on
 the majority of the comments, EPA has
 retained the plain language format used
 in the January 9,1998, proposal in
 today's final rule.
  The proposal to today's final rule
 included guidance as well as legal
 requirements. The word "must"
 indicates a requirement. Words like
 "should," "could," or "encourage"
 indicate a recommendation or guidance.
 In addition,  the guidance was set off in
 parentheses to distinguish it from
 requirements.
  EPA received numerous comments
 supporting the inclusion of guidance in
 the text of the Code of Federal
 Regulations  (CFR), as well as comments
 opposing inclusion of guidance.
 Supporters stated that preambles and
 guidance documents are often not
 accessible when rules are implemented.
 Any language not included  in the CFR
 is therefore not available when it may be
 most needed. Commenters that opposed
 including guidance in the CFR
 expressed the concern that any language
 in the rule might be interpreted as a
 requirement, in spite of any clarifying
 language. They suggested that guidance
 be presented in the preamble and
 additional guidance documents.
  The majority of commenters on this
 issue  thought that the guidance should
 be retained but the distinction between
 requirements and guidance  should be
 better clarified. Suggestions included
 clarifying text, symbols, and a change
 from use of the word "should" to "EPA
 recommends" or "EPA suggests". EPA
 believes that it is important  to include
 the guidance in the rule and agrees that
 the distinction between requirements
 and EPA recommendations must be very
 clear. In today's final rule, EPA has put
 the guidance in paragraphs entitled
 "Guidance" and replaced the word
 "should" with "EPA recommends."
This is intended to clarify that the
 recommendations contained in the
guidance paragraphs are not legally
binding.
 C. Program Framework: NPDES
Approach
  Today's rule regulates Phase II
sources using the NPDES permit
program. EPA interprets Clean Water
Act section 402(p)(6) as authorizing the
Agency to develop a storm water
program for Phase II sources either as
part of the existing NPDES permit
program or as a stand alone non-NPDES
program such as a self-implementing
rule. Under either approach, EPA
interprets section 402(p)(6) as directing
EPA to publish regulations that
"regulate" the remaining unregulated
sources, specifically to establish
requirements that are federally
enforceable under the CWA. Although
EPA believes that it has the discretion
to not require sources regulated under
CWA section 402(p)(6) to be covered by
NPDES permits, the Agency has
determined, for the reasons discussed
below, that it is most appropriate to use
NPDES permits in implementing the
program to address the sources
designated for regulation in today's rule.
  As discussed in Section II.A,
Overview, EPA sought to achieve
certain goals in today's final rule. EPA
believes that the NPDES program best
achieves EPA's goals for today's final
rule for the reasons discussed below.
  Requiring Phase II sources to be
covered by NPDES permits helps
address the consistency problems
currently caused by municipal "donut
holes." Donut holes are gaps in program
coverage where a small unregulated
MS4 is located next to or within a
regulated larger MS4 that is subject to
an NPDES permit  under the Phase I
NPDES storm water program. The
existence of such "donut holes" creates
an equity problem because similar
discharges may remain unregulated
even though they cause or contribute to
the same adverse water quality impacts.
Using NPDES permits to regulate the
unregulated discharges in these areas is
intended to facilitate the development
of a seamless regulatory program for the
mitigation and control of contaminated
storm water discharges in an urbanized
area. For example, today's rule allows a
newly regulated MS4 to join as a
"limited" co-permittee with a regulated
MS4 by referencing a  common storm
water management program. Such
cooperation should be further
encouraged by the fact that the
minimum control  measures required in
today's rule for regulated small MS4s
are very similar to a number of the
permit requirements for medium and
large MS4s under the Phase I storm
water program. The minimum control
measures applicable to discharges from
smaller MS4s are described with
slightly more generality than under the
Phase I permit  application regulations
for larger MS4s, thus enabling
maximum flexibility for operators of
smaller MS4s to optimize efforts to
protect water quality.
  Today's rule also applies NPDES
permit requirements to construction
sites below 5 acres that are similar to the
existing requirements for those 5 acres
and above. In addition, the rule would
allow compliance with qualifying local,
Tribal, or State erosion and sediment
controls to meet the erosion and
sediment control requirements of the
general permits for storm water
discharges associated with construction,
both above and below 5 acres.
  Incorporating the CWA section
402(p)(6) program into the NPDES
program capitalizes upon the existing
governmental infrastructure for
administration of the NPDES program.
Moreover, much of the regulated
community already understands the
NPDES program and the way it works.
  Another goal of the NPDES program
approach is to provide flexibility in
order to facilitate and promote
watershed planning and sensitivity to
local conditions. NPDES permits
promote those goals in several ways.
NPDES general permits may be used to
cover a category of regulated sources on
a watershed basis or within political
boundaries. The NPDES  permitting
process provides a mechanism for storm
water controls tailored on a case-by-case
basis, where necessary. In addition, the
NPDES permit requirements of a
permittee may be satisfied by another
cooperating entity. Finally, NPDES
permits may incorporate the
requirements of existing  State, Tribal
and local programs, thereby
accommodating State and Tribes
seeking to coordinate the storm water
program with other programs, including
those that focus on watershed-based
nonpoint source regulation.
  In promoting the watershed approach
to program administration, EPA believes
NPDES general permits can cover a
category of dischargers within a defined
geographic area. Areas can be defined
very broadly to include political
boundaries (e.g., county), watershed
boundaries, or State or Tribal land.
  NPDES permits generally require an
application or a notice of intent(NOI) to
trigger coverage. This information
exchange assures communication
between the permitting authority and
the regulated community. This
communication is critical in ensuring
that the regulated community is aware
of the requirements and the permitting
authority is aware of the  potential for
adverse impacts to water quality from
identifiable locations. The NPDES
permitting process includes the public
as a valuable stakeholder and ensures

-------
 68740    Federal Register/Vol. 64, No.  235/Wednesday, December 8, 1999/Rules and  Regulations
 that the public is included and
 information is made publicly available.
   Another concern for EPA and several
 stakeholders was that the program
 ensure citizen participation. The NPDES
 approach ensures opportunities for
 citizen participation throughout the
 permit issuance process, as well as in
 enforcement actions. NPDES permits are
 also federally enforceable under the
 CWA.
   EPA believes that the use of NPDES
 permits makes a significant difference in
 the degree of compliance with
 regulations in the storm water program.
 The NPDES program provides for public
 participation in the development,
 enforcement and revision of storm water
 management programs. Citizen suit
 enforcement has assisted in focusing
 attention on adverse water  quality
 impacts on a localized, public priority
 basis. Citizens frequently rely on the
 NPDES permitting process  and the
 availability of NOIs to track program
 implementation and help them enforce
 regulatory requirements.
   NPDES permits are also advantageous
 to the permittee. The NPDES permit
 informs the permittee about the scope of
 what it is expected do to be in
 compliance with the Clean  Water Act.
 As explained more fully in  EPA's April
 1995 guidance, Policy Statement on
 Scope of Discharge Authorization and
 Shield Associated with NPDES Permits,
 compliance with an NPDES permit
 constitutes compliance with the Clean
 Water Act (see CWA section 402(k)). In
 addition, NPDES permittees are
 excluded from duplicative regulatory
 regimes under the Resource
 Conservation and Recovery Act and the
 Comprehensive Emergency Response,
 Compensation and Liability Act under
 RCRA's exclusions to the definition of
 "solid waste" and CERCLA's exemption
 for "federally permitted releases."
  EPA considered suggestions that the
 Agency authorize today's rule to be
 implemented as a self-implementing
 rule. This would be a regulation
 promulgated at the Federal, State, or
 Tribal level to  control some or all of the
 storm water dischargers regulated under
 today's rule. Under this approach,  a rule
 would spell out the specific
 requirements for dischargers and
 impose the restrictions and  conditions
that would otherwise be contained in an
NPDES permit. It would be effective
until modified by EPA, a State, or a
Tribe, unlike an NPDES permit which
cannot exceed  a duration of five years.
Some stakeholders believed that this
approach would reduce the  burden on
the regulated community (e.g., by not
requiring permit applications),  and
considerably reduce the amount of
 additional paperwork, staff time and
 accounting required to administer the
 proposed permit requirements.
   EPA is sensitive to the interest of
 some stakeholders in having a
 streamlined program that minimizes the
 burden associated with permit
 administration and maximizes
 opportunities for field time spent by
 regulatory authorities. Key provisions in
 today's rule address some of these
 concerns by promoting a streamlined
 approach to permit issuance by, for
 example, using general permits and
 allowing the incorporation of existing
 programs. By adopting the NPDES
 approach rather than a self-
 implementing rule, today's rule also
 allows  for consistent regulation between
 larger MS4s and construction sites
 regulated under the existing storm water
 management rule and smaller sources
 regulated under today's rule.
   EPA  believes that it is most
 appropriate to use NPDES permits to
 implement a program to address the
 sources regulated by today's rule. In
 addition to the reasons discussed above,
 NPDES permits provide a better
 mechanism than would a self-
 implementing rule for tailoring storm
 water controls on a case-by-case basis,
 where necessary. One commenter
 reasoned this concern could be
 addressed by including provisions in
 the regulation that allow site-specific
 BMPs (i.e., case-by-case permits],
 suggesting storm water discharges that
 might require site-specific BMPs can be
 identified during the designation
 process of the regulatory authority. EPA
 believes that, in addition to its
 complexity, the commenter's approach
 lacks the other advantages of the NPDES
 permitting process.
  A self-implementing rule would not
 ensure the degree of public participation
 that the NPDES permit process provides
 for the development, enforcement and
 revision of the storm water management
 program. A self-implementing rule also
 might not have provided the regulated
 community the "permit shield" under
 CWA section 402(k) that is provided by
 an NPDES permit. Based on all these
 considerations, EPA declined to adopt a
 self-implementing rule approach and
 adopted the NPDES approach.
  Some State representatives sought
alternative approaches for State
implementation of the storm water
program for Phase II sources. These
State representatives asserted that a
non-NPDES alternative approach best
facilitated watershed management and
avoided duplication and overlapping
regulations. These representatives
believed the NPDES approach would
undercut State programs that had
 developed storm water controls tailored
 to local watershed concerns. Finally, a
 number of commenters expressed the
 view that States implement a variety of
 programs not based on the CWA that are
 effective in controlling storm water, and
 that EPA should provide incentives for
 their implementation and improvement
 in performance.
   Throughout the development of the
 rule, State representatives sought
 alternatives to the NPDES approach for
 State implementation of the storm water
 program for Phase II sources.
 Discussions focused on an approach
 whereby States could develop an
 alternative program that EPA would
 approve or disapprove based on
 identified criteria, including that the
 alternative non-NPDES program would
 result in "equivalent or better protection
 of water quality." The State
 representatives, however, were  unable
 to propose or recommend criteria for
 gauging whether a program would
 provide equivalent protection. EPA also
 did not receive any suggestions  for
 objective, workable criteria in response
 to the Agency's explicit request  for
 specific criteria (by which EPA could
 objectively judge such programs) in the
 preamble to the proposed rule.
   EPA evaluated several existing State
 initiatives to address storm water and
 found many cases where standards
 under State programs may be
 coordinated with the Federal storm
 water program. Where the NPDES
 permit is developed in  coordination
 with State standards, there are
 opportunities to avoid duplication and
 overlapping requirements. Under
 today's rule, an NPDES permitting
 authority may include conditions in the
 NPDES  permit that direct an MS4 to
 follow the requirements imposed under
 State standards, rather than the
 requirements of § 122.34(b). This is
 allowed as  long as the State program at
 a minimum imposes the relevant
 requirements of § 122.34(b). Additional
 opportunities follow from other
 provisions in today's rule.
   Seeking to further explore the
 feasibility of a non-NPDES approach,
 the Agency, after the proposal, had
 extensive discussions with
 representatives of a number of States.
 Discussions related specifically to
 possible alternatives for regulations of
 urban storm water discharges and MS4s
 specifically. The Agency also sought
 input on these issues from other
 stakeholders.
  As a result of these discussions, many
 of the commenters provided input on
issues such as: whether or not the
Agency should require NPDES permits;
whether location of MS4s  in urbanized

-------
           Federal Register/Vol.  64,  No. 235/Wednesday, December 8,  1999/Rules and Regulations     68741
 areas should be the basis for designation
 or whether designation should be based
 on other determinations relating to
 water quality; whether States should be •
 allowed to satisfy the conditions of the
 rule through the use of existing State
 programs; and issues concerning timing
 and resources for program
 implementation.
   In response, today's rule still follows
 the regulatory scheme of the proposed
 rule, but incorporates additional
 flexibility to address some of the
 concerns raised by commenters.
   In order to facilitate implementation
 by States that utilize a watershed
 permitting approach or similar approach
 (i.e., based on a State's unified
 watershed assessments), today's rule
 allows States to phase in coverage for
 MS4s in jurisdictions with a population
 less than 10,000. Under such an
 approach, States could focus their
 resources on a rolling basis to assist
 smaller MS4s in developing storm water
 programs.
   In addition, in response to concerns
 that the rule should not require permit
 coverage for MS4s that do not
 significantly contribute to water quality
 impairments, today's rule provides
 options for two waivers for small MS4s.
 Tne rule allows permitting authorities to
 exempt from the requirement for a
 permit any MS4 serving a jurisdiction
 with a population less than 1,000,
 unless the State determines that the
 MS4 must implement storm water
 controls because it is significantly
 contributing to a water quality
 impairment. A second waiver option
 applies to MS4s serving a jurisdiction
 with a population less than 10,000. For
 those MS4s, the State must determine
 that discharges from the MS4 do not
 significantly contribute to a water
 quality impairment, or have the
 potential for such an impairment, in
 order to provide the exemption. The
 State must review this waiver on a
 periodic basis no less frequently than
 once every five years.
  Throughout the development of
 today's rule, commenters questioned
 whether the Clean Water Act authorized
 the use of the NPDES permit program,
 pointing out that the text of CWA
402(p)(6) does not use the word
 "permit." Based on the absence of the
word "permit" and the express mention
of State storm water management
programs, the commenters asserted that
Congress did not intend for Phase II
sources to be regulated using NPDES
permits.
  EPA disagrees with the commenters'
interpretation of section 402(p)(6).
Section 402(p)(6) does not preclude use
of permits as part of the
 "comprehensive program" to regulate
 designated sources. The language
 provides EPA with broad discretion in
 the establishment of the
 "comprehensive program." Absence of
 the word "permit" (a term that the
 statute does not otherwise define) does
 not preclude use of a permit, which is
 a familiar and reasonably well
 understood regulatory implementation
 vehicle. First, section 402(p)(6) says that
 EPA must establish a comprehensive
 program that "shall, at a minimum,
 establish priorities,  establish
 requirements for State stormwater
 management programs, and establish
 expeditious deadlines." The  "at a
 minimum" language suggests that the
 Agency may, and perhaps should,
 develop a comprehensive program that
 does more than merely attend to these
 minimum criteria. Use of the term "at a
 minimum" preserves for the Agency
 broad discretion to establish a
 comprehensive program that includes
 use of NPDES permits.
  Further, in the final sentence of the
 section, Congress included additional
 language to affirm the Agency's
 discretion. The final sentence clarifies
 that the Phase II program "may include
 performance standards, guidelines,
 guidance, and management practices
 and treatment requirements, as
 appropriate." Under existing CWA
 programs, performance standards,
 (effluent limitations) guidelines,
 management practices, and treatment
 requirements are typically implemented
 through NPDES or dredge and fill
 permits.
  Although EPA believes that it had the
 discretion to not require permits, the
 Agency has determined that it is
 reasonable to interpret section 402(p)(6)
 to authorize permits. Moreover, for the
 reasons discussed above, the Agency
 believes that it is appropriate to use
 NPDES permits in implementing today's
 rule.

 D. Federal Role
  Today's final rule describes EPA's
 approach to expand the existing storm
 water program under CWA section
 402(p)(6). As in all other Federal
 programs, the Federal government plays
 an integral role in complying with,
 developing, implementing, overseeing,
 and enforcing the program. This  section
 describes EPA's role in the revised
 storm water program.

 1. Develop Overall Framework of the
Program
  The storm water discharge control
program under CWA section 402(p)(6)
 consists of the rule, tool box, and
permits. EPA's primary role is to ensure
 timely development and
 implementation of all components.
 Today's rule is a refinement of the first
 step in developing the program. EPA is
 fully committed to continuing to work
 with involved stakeholders on
 developing the tool box and issuing
 permits. As noted in today's rule, EPA
 will assess the municipal storm water
 program based on (1) evaluations of data
 from the NPDES municipal storm water
 program, (2) research concerning water
 quality impacts on receiving waters
 from storm water, and (3) research on
 BMP effectiveness. (Section II.H,
 Municipal Role, provides a more
 detailed discussion of this provision.)
  EPA is planning to standardize
 minimum requirements for construction
 and post-construction BMPs in a new
 rulemaking under Title III of the CWA.
 While larger construction sites are
 already subject to NPDES permits (and
 smaller sites will be subject to permits
 pursuant to today's rule), the permits
 generally do not contain specific
 requirements for BMP design or
 performance. The permits require the
 preparation of storm water pollution
 prevention plans, but actual BMP
 selection and design is at the discretion
 of permittees, in conformance with
 applicable State and local requirements.
 Where there are existing State and local
 requirements specific to BMPs, they
 vary widely, and many jurisdictions do
 not have such requirements.
  In developing these regulations, EPA
 intends to evaluate the inclusion of
 design and maintenance criteria as
 minimum requirements for a variety of
 BMPs used for erosion and sediment
 control at construction sites, as well as
 for permanent BMPs used to manage
 post-construction storm water
 discharges. The Agency plans to
 consider the merits and performance of
 all appropriate management practices
 (both structural and non-structural) that
 can be used to reduce adverse water
 quality impacts. EPA does not intend to
 require the use of particular BMPs at
 specific sites, but plans to assist
builders and developers in BMP
selection by publishing data on the
performance to be expected by various
BMP types. EPA would like to build
upon the successes of some of the
effective State and local storm water
programs currently in place around the
country, and to establish nation-wide
criteria to support builders and local
jurisdictions in appropriate BMP
selection.

2. Encourage Consideration of Smart
Growth Approaches
  In the proposal, EPA invited comment
on possible approaches for providing

-------
68742    Federal Register/Vol.  64,  No. 235/Wednesday, December 8,  1999/Rules and Regulations
incentives for local decision making that
would limit the adverse impacts of
growth and development on water
quality. EPA asked for comments on this.
"smart growth" approach.
  EPA received comments on all sides
of this issue. A number of commenters
supported the idea of "smart growth"
incentives but did not present concrete
ideas. Several commenters suggested
"smart growth" criteria. States that have
adopted "smart growth" laws were
worried that EPA's focus on urbanized
areas for municipal requirements could
encourage development outside of
designated growth areas. Today's final
rule clearly allows States to expand
coverage of their municipal storm water
program outside of urbanized areas. In
addition, the flexibility of the six
municipal minimum measures  should
avoid encouragement of development
into rural rather than urban areas. For
example, as part of the post-
construction minimum measure, EPA
recommends that municipalities
consider policies and ordinances that
.encourage infill development in higher
density urban areas, and areas with
existing infrastructure, in order to meet
the measure's intent.
  EPA also received several comments
expressing concern that incorporating
"smart growth" incentives threatened
the autonomy of local governments. One
commenter was worried that
"incentives" could become more
onerous than the minimum measures.
EPA is very aware of municipal
concerns about possible federal
interference with local land use
planning. EPA is also  cognizant of the
difficulty surrounding incentives for
"smart growth" activities due to these
concerns. However, the Agency believes
it has addressed these concerns by
proposing a flexible approach and will
continue to support the concept of
"smart growth" by encouraging policies
that limit the adverse  impacts of growth
and development on water quality.
3. Provide Financial Assistance
   Although Congress  has not
established a fund to fully finance
implementation of the proposed
extension of the existing NPDES storm
water program  under CWA section
402(p)(6), numerous federal financing
programs (administered by EPA and
other federal agencies) can provide
some financial assistance. The primary
funding mechanism is the Clean Water
State Revolving Fund (SRF) program,
which provides sources of low-cost
 financing for a range of water quality
 infrastructure projects, including storm
 water. In addition to the SRF, federal
 financial assistance programs include
the Water Quality Cooperative
Agreements under CWA section
104(b)(3), Water Pollution Control
Program grants to States under CWA
section 106, and the Transportation
Equity Act for the 21st Century (TEA-
21) among others. In addition, Section
319 funds may be used to fund any
urban storm water activities that are not
specifically required by a draft or final
NPDES permit. EPA will develop a list
of potential funding sources as part of
the tool box implementation effort. EPA
anticipates that some of these programs
will provide funds to help develop and,
in limited circumstances, implement the
CWA section 402(p)(6) storm water
discharge control program.
  EPA received numerous comments
that requested additional funding.
Congress provided one substantial  new
source of potential funding for
transportation related storm water
projects—TEA-21. The Department of
Transportation has included a number
of water-related provisions in its TEA-
21 planning. These include
Transportation Enhancements,
Environmental Restoration and
Pollution Abatement, and
Environmental Streamlining. More
information on TEA—21 is available at
the following internet sites:
www.fhwa.dot.gov/tea21/outreach.htm
and www.tea21.org.

4. Implement the Program in
Jurisdictions Not Authorized To
Administer the NPDES Program
   Because today's final rule uses the
NPDES framework, EPA will be the
NPDES permitting authority in several
States, Tribal jurisdictions, and
Territories. As such,  EPA will have the
same responsibilities as any other
NPDES permitting authority—issuing
permits,  designating  additional sources,
and taking appropriate enforcement
actions—and will seek to tailor the
storm water discharge control program
to the specific needs  in that State, Tribal
jurisdiction, or Territory. EPA also plans
to provide support and oversight,
including outreach, training, and
technical assistance to the regulated
communities. Section II.G. of today's
preamble provides a  separate discussion
related to the NPDES permitting
authority's responsibilities for today's
final rule.
5. Oversee State and Tribal Programs
   Under the NPDES  program, EPA plays
an oversight role for  NPDES-approved
States and Tribes. In this role, EPA and
the State or Tribe work together to
implement, enforce,  and improve the
NPDES program. Part of this oversight
role includes working with States  and
Tribes to modify their programs where
programmatic or implementation
concerns impede program effectiveness.
This role will be vitally important when
States and Tribes make adjustments to
develop, implement, and enforce
today's extension of the existing NPDES
storm water discharge control program.
In addition, States maintain a
continuing planning process (CPP)
under CWA section 303(e), which EPA
periodically reviews to assess the
program's achievements.
  In its oversight role, EPA takes action
to address States and Tribes who have
obtained NPDES authorization but are
not fulfilling their obligations under the
NPDES program. If an NPDES-
authorized State or Tribe fails to
implement an adequate NPDES storm
water program, for example, EPA
typically enters into extensive
discussions to  resolve outstanding
issues. EPA has the authority to
withdraw the entire NPDES program
when resolution cannot be reached.
Partial program withdrawal is not
provided for under the CWA except for
partial approvals.
  EPA is also working with the States
and Tribes to improve nonpoint source
management programs and assessments
to incorporate  key program  elements.
Key nonpoint source program elements
include setting short and long term
goals and objectives; establishing public
and private partnerships; using a
balanced approach incorporating
Statewide and watershed-wide
abatement of existing impairments;
preventing future impairments;
developing processes to address both
impaired and threatened waters;
reviewing and upgrading all program
components, including program
revisions on a  5-year cycle; addressing
federal land management and activities
inconsistent with State programs; and
managing State nonpoint source
management programs effectively.
   In particular, EPA works with the
States and Tribes to strengthen their
nonpoint source pollution programs to
address all significant nonpoint sources,
including agricultural sources, through
the CWA section 319 program. EPA is
working with other government
agencies,  as well as with community
groups, to effect voluntary changes
regarding watershed protection and
reduced nonpoint source pollution.
   In addition, EPA and NOAA have
published programmatic and technical
guidance to address coastal nonpoint
source pollution. Under Section 6217 of
the CZARA, States are developing and
implementing coastal nonpoint
pollution control programs approved by
EPA and NOAA.

  6. Comply With Applicable
  Requirements as a Discharger
   Today's final rule covers federally
  operated facilities in a variety of ways.
  These facilities are generally areas
  where people reside, such as a federal
  prison, hospital, or military base. It also
  includes federal parkways and road
  systems with separate storm sewer
  systems. Today's rule requires federal
  MS4s to comply with the same
  application deadlines that apply to
  regulated small MS4s generally. EPA
  believes that all federal MS4s serve
  populations of less than 100,000.
   EPA received several comments that
  asked if individual buildings like post
  offices are considered to be small MS4s
  and thereby regulated in today's rule if
  they are in an urbanized area. Most of
  these buildings have at most a parking
  lot with runoff or a storm sewer that
  connects with a municipality's MS4.
 EPA does not intend that individual
  federal buildings be considered to be
 small MS4s. This is discussed in section
 II.H.Z.b. of today's preamble.
   Federal facilities can also be included
 under requirements addressing storm
 water discharges associated with small
 construction activities. In any case,
 discharges from these facilities will
 need to comply with all applicable
 NPDES requirements and any additional
 water quality-related requirements
 imposed by a State, Tribal, or local
 government. Failure to comply can
 result in enforcement actions. Federal
 facilities can act as models for
 municipal and private sector facilities
 and implement or test state-of-the-art
 management practices and control
 measures.
 E. State Role
  Today's final rule sets forth an NPDES
 approach for implementing the
 extension of the existing storm water
 discharge control program under CWA
 section 402(p)(6). State assumption of
 the NPDES program is voluntary,
 consistent with the principles of
 federalism. Because most States are
 approved to implement the NPDES
 program, they will tailor their storm
 water discharge control programs to
 address their water quality needs and
 objectives. While today's rule
 establishes the basic framework for the
 section 402(p)(6) program, States as well
 as Tribes (see discussion in section II.F)
 have an important role in fine-tuning
 the program to address the water quality
 issues within their jurisdictions. The
 basic framework allows for adjustments
 based on factors that vary
geographically, including climate
patterns and terrain.
    Where States do not have NPDES
  authority, they are not required to
  implement the storm water discharge
.  control program, but they may still
  participate in water quality protection
  through participation in the CWA
  section 401 certification process (for any
  permits) and through development of
  water quality standards and TMDLs.
  1. Develop the Program
    In expanding the existing NPDES
  program for storm water discharges,
  States must evaluate whether revisions
  to their NPDES programs are necessary.
  If so, modifications must be made in
  accordance with § 123.62. Under
  § 123.62, States must revise their NPDES
  programs within 1 year, or within 2
  years if statutory changes are necessary.
   Some States and departments of
  transportation (DOTs) commented that
  this timeframe is too short, anticipating
  that the State legislative process and the
  modification  of regulations combined
  would take beyond 2 years. The
  deadline language in § 123.62 is not new
  language for the storm water discharge
  control program; it applies to all NPDES
  programs. EPA believes the vast
  majority of States will meet the deadline
  and will work with States in those cases
  where there may be difficulty meeting
  this deadline  due to the timing  of
  legislative sessions and the regulatory
  development  process.
   An authorized State NPDES program
  must meet the requirements of CWA
  section 402(b) and conform to the
 guidelines issued under CWA section
  304(i)(2). Today's final rule under
  § 123.25 adds specific cross references
 to the storm water discharge control
 program components to ensure that
 States adequately address these
 requirements.

 2. Comply With Applicable
 Requirements as a Discharger
  Today's final rule covers State
 operated separate storm sewer systems
 in a variety of ways. These systems
 generally drain areas where people
 reside, such as a prison, hospital, or
 other populated facility. These systems
 are included under the definition of a
 regulated small MS4, which specifically
 identifies systems operated by State
 departments of transportation.
 Alternatively, storm water discharges
 from State activities may be regulated
 under the section addressing storm
 water discharges associated with small
 construction activities. In any case,
 discharges from these facilities must
 comply with all applicable NPDES
 requirements.  Failure to comply can
 result in enforcement actions. State
 facilities can act as models for •
 municipal and private sector facilities
 and implement or test state-of-the-art
 management practices and control
 measures.

 3. Communicate With EPA

   Under approved NPDES programs,
 States have an ongoing obligation to
 share information with EPA. This
 dialogue is particularly important in the
 CWA section 402(p)(6) storm water
 program where these governments
 continue to develop a great deal of the
 guidance and outreach related to water
 quality.

 F. Tribal Role

   The proposal to today's final rule
 provides background information on
 EPA's 1984 Indian Policy and the
 criteria for treatment of an Indian Tribe
 in the same manner as a State. Today's
 final rule extends the existing NPDES
 program for storm water discharges to
 two types of dischargers located in
 Indian country. First, the final rule
 designates storm water discharges from
 any regulated small MS4,  including
 Tribal systems. Second, the final rule
 regulates discharges associated with
 construction activity disturbing between
 one and five acres of land, including
 sites located in Indian country.
 Operators in each of these categories of
 regulated activity must apply for
 coverage under an NPDES permit by 3
 years and 90 days from the date of
 publication of today's final rule. Under
 existing regulations, however, EPA or an
 authorized NPDES Tribe may require a
 specified storm water discharger to
 apply for NPDES permit coverage before
 this  deadline based on a determination
 that the discharge is contributing to a
 violation of a water quality standard
 (including designated uses) or is a
 significant contributor of pollutants.
   Under today's rule, a Tribal
 governmental entity may regulate storm
 water discharges on its  reservation in
 two ways—as either an NPDES-
 authorized Tribe or as a regulated MS4.
 If a Tribe is authorized to operate the
 NPDES program, the Tribe must
 implement today's  final rule  for the
 NPDES program for storm  water for
 covered dischargers located within the
 EPA recognized boundaries. Otherwise,
 EPA is generally the permitting/program
 authority within Indian country.
 Discussions about the State Role in the
 preceding section also apply  to NPDES
 authorized Tribes. For additional
 information on the role and
responsibilities of the permitting
 authority in the NPDES storm water
program, see § 123.35 (and Section II.G.
of today's preamble) and § 123.25(a).

-------
 68744    Federal Register/Vol.  64, No.  2 35/Wednesday,  December  8, 1999/Rules and Regulations
   Under today's final rule, if the Indian
 reservation is located entirely or
 partially within an "urbanized area," as
 defined in § 122.32(a)(l), the Tribe must-
 obtain an NPDES permit if it operates a
 small MS4 within the urbanized area
 portion. Tribal MS4s located outside an
 urbanized area are not automatically
 covered, but may be designated by EPA
 pursuant to § 122.32(a)(2) of today's rule
 or may request designation as a
 regulated small MS4 from EPA. A Tribe
 that is a regulated MS4 for NPDES
 program purposes is required to
 implement the six minimum control
 measures to the extent allowable under
 Federal law.
   The Tribal representative on the
 Storm Water Phase II FACA
 Subcommittee asked EPA to provide a
 list of the Tribes located in urbanized
 areas that would fall within the NPDES
 storm water program under today's final
 rule. In December 1996, EPA-developed
 a list of federally recognized American
 Indian Areas located wholly or partially
 in Bureau of the Census-designated
 urbanized areas (see Appendix 1).
 Appendix 1 not only provides a listing
 of reservations and individual Tribes,
 but also the name of the particular
 urbanized area in which the  reservation
 is located and an indication of whether
 the urbanized area contains a medium
 or large MS4 that is already covered by
 the existing Phase I regulations.
   Some of the Tribes listed in Appendix
 1 are only partially located in an
 urbanized area. If the Tribe's MS4 serves
 less than 1,000 people within an
 urbanized area, the permitting authority
 may waive the Tribe's MS4 storm water
 requirements if it meets the conditions
 of § 122.32(c). EPA does not have
 information on the Tribal populations
 within the urbanized areas, so it can not
 identify the Tribes that are eligible for
 a waiver. Therefore, a Tribe that
 believes it qualifies for a waiver should
 contact its permitting authority.
 G. NPDES Permitting Authority's Role
for the NPDES Storm Water Small MS4
 Program
  As noted previously, the NPDES
 permitting authority can be EPA or an
 authorized State or an authorized Tribe.
 The following discussion describes the
 role of the NPDES permitting authority
 under today's final rule.
 1. Comply With Implementation
 Requirements
  NPDES permitting authorities must
 perform certain duties to implement the
 NPDES storm water municipal program.
 Section 123.35(a) of today's final rule
 emphasizes that permitting authorities
 have existing obligations under the
 NPDES program. Section 123.35 focuses
 on specific issues related to the role of
 the NPDES authority to support
 administration and implementation of
 the municipal storm water program
 under CWA section 402(p)(6).
 2. Designate Sources

   Section 123.35(b) of today's final rule
 addresses the requirements for the
 NPDES permitting authority to
 designate sources of storm water
 discharges to be regulated under
 §§ 122.32 through 122.36. NPDES
 permitting authorities must develop a
 process, as well as criteria, to designate
 small MS4s. They must also have the
 authority to designate a small MS4  if
 and when circumstances that support a
 waiver under § 122.32(c) change. EPA
 may make designations if an NPDES-
 approved State or Tribe fails to do so.
   NPDES permitting authorities must
 examine geographic jurisdictions that
 they believe should be included in the
 storm water discharge control program
 but are not located in an "urbanized
 area".  Small MS4s in these areas are not
 designated automatically. Discharges
 from such areas should be brought into
 the program if found to have actual or
 potential exceedances of water quality
 standards, including impairment of
 designated uses, or other adverse
 impacts on water quality, as determined
 by local conditions or watershed and
 TMDL assessments. EPA's aim is to
 address discharges to impaired waters
 and to protect waters with the potential
 for problems. EPA encourages NPDES
 permitting authorities, local
 governments, and the interested public
 to work together in the context of a
 watershed plan to address water quality
 issues, including those associated with
 municipal storm water runoff.
  EPA received comments stating that
 the process of developing criteria and
 applying it to all MS4s outside an
 urbanized area serving a population of
 10,000 or greater and with a density of
 1,000 people per square mile is too
 time-consuming and resource-intensive.
 These commenters believe that the
 permitting authority should decide
 which  MS4s must be brought into the
 storm water discharge control program
 and that population and density should
 not be an overriding criteria. One
 suggested way of doing so was to only
 designate MS4s with demonstrated
 contributions to the impairment of
 water quality uses as shown by a TMDL.
 EPA disagrees with this suggestion.  The
 TMDL  process is time-consuming. MS4s
 outside of urbanized areas may cause
 water quality problems long before a
TMDL  is completed.
   EPA believes that permitting
 authorities should consider the
 potential water quality impacts of storm
 water from all jurisdictions with a
 population of 10,000 or greater and a
 density of 1,000 people per square mile.
 EPA is using data summarized in the
 NURP study and in the CWA section
 305(b) reports to support this approach
 for targeted designation outside of
 urbanized areas. EPA is not mandating
 which criteria are to be used, but has
' provided examples of criteria that may
 be useful in evaluating potential water
 quality impacts. EPA believes that the
 flexibility provided in this section of
 today's final rule allows  the permitting
 authority to develop criteria and a
 designation process that is easy to use
 and protects water quality. Therefore,
 the provisions of § 123.35(b) remain as
 proposed.

 a. Develop Designation Criteria
   Under § 123.35(b), the NPDES
 permitting authority must establish
 designation criteria to evaluate whether
 a storm water discharge results in or has
 the potential to result in  exceedances of
 water quality standards,  including
 impairment of designated uses, or other
 significant water quality impacts,
 including adverse habitat and biological
 impacts.
   EPA recommends that NPDES
 permitting authorities consider, in a
 balanced manner, certain locally-
 focused criteria  for designating any  MS4
 located outside of an urbanized area on
 the basis of significant water quality
 impacts. EPA recommends
 consideration of criteria such as
 discharge to sensitive waters, high
 growth or growth potential, high
 population  density, contiguity to an
 urbanized area, significant contribution
 of pollutants to waters of the United
 States, and ineffective control of water
 quality concerns by other programs.
 These suggested designation criteria are
 intended to help encourage the
 permitting authority to use an objective
 method for identifying and designating,
 on a local basis, sources that adversely
 impact water quality. More information
 about these criteria and the reasons  why
 they are suggested by EPA is included
 in the January 9,1998, proposal (63  FR
 1561) for today's final rule.
  The suggested criteria are meant to be
 taken in the aggregate, with a great deal
 of flexibility as to how each should be
 weighed in order to best account for
 watershed and other local conditions
 and to allow for a more tailored case-by-
 case analysis. The application of criteria
 is meant to be geographically specific.
 Furthermore, each criterion does hot
 have  to be met in order for a small MS4

-------
            Federal Register/Vol. 64, No.  235/Wednesday,  December  8,  1999/Rules and Regulations    68745
  to qualify for designation, nor should an
  MS4 necessarily be designated on the
  basis of one or two criteria alone.
   EPA believes that the application of
  the recommended designation criteria
  provides an objective indicator of real
  and potential water quality impacts
  from urban runoff on both the local and
  watershed levels. EPA encourages the
  application of the recommended criteria
  in a watershed context, thereby allowing
  for the evaluation of the water quality
  impacts of the portions of a watershed  •
  outside of an urbanized area. For
  example, situations exist where the
  urbanized area represents a small
  portion of a degraded watershed, and
  the adjacent nonurbanized areas of the
  \vatershed have significant cumulative
  effects on the quality of the receiving
  waters.
   EPA received numerous suggestions
  of additional criteria that should be
 added and reasons why some of the
 criteria in the proposal to today's final
 rule were not appropriate. EPA
 developed its suggested designation
 criteria based on findings of the NURP
 study and other studies that indicate
 pollutants of concern, including total
 suspended solids, chemical oxygen
 demand, and temperature. These  criteria
 were the subject of considerable
 discussion by the  Storm Water Phase II
 FACA Subcommittee. EPA developed
 them in  response to recommendations
 from the subcommittee during
 development of the proposed rule. The
 listed criteria are only suggestions.
 Permitting authorities are required to
 develop their own criteria. EPA has not
 found any reason to change its
 suggested list of criteria and the
 suggestions remain as proposed.
 b. Apply Designation Criteria
   After customizing the designation
 criteria for local conditions, the
 permitting authority must apply such
 criteria, at a minimum, to any MS4
 located outside of  an urbanized area
 serving a jurisdiction with a population
 of at least 10,000 and a population
 density of 1,000 people per square mile
 or greater (see §123.35(b)(2)). If the
 NPDES permitting authority determines
 that an MS4 meets the criteria, the
permitting authority must designate it as
a regulated small MS4. This designation
must occur within  3 years of publication
of today's final rule. Alternatively, the
NPDES authority can designate within 5
years from the date of final regulation if
the designation criteria are applied on a
watershed basis where a comprehensive
watershed plan exists (a comprehensive
watershed plan is one that includes the
equivalents of TMDLs) (see
§ 123.35(b)(3)). The extended 5 year
  deadline is intended to provide
  incentives for watershed-based
  designations. If an NPDES-authorized
  State or Tribe does not develop and
  apply designation criteria within this
  timeframe, then EPA has the
  opportunity to do so in lieu of the
  authorized State or Tribe.
   NPDES permitting authorities can
  designate any small MS4, including one
  below 10,000 in population and 1,000 in
  density. EPA established the 10.000/
  1,000 threshold based on the likelihood
  of adverse water quality impacts at these
 population and density levels. In
 addition, the 1,000 persons per square
 mile threshold is consistent with both
 the Bureau of the Census definition of
 an "urbanized area" (see Section II.H.2.
 below) and stakeholder discussions
 concerning the definition of a regulated
 small MS4.
   One commenter requested that EPA
 develop interim deadlines for
 development of designation criteria.
 EPA believes that the designation
 deadline identified in today's final rule
 at § 123.35(b)(3) provides States and
 Tribes with a flexibility that allows
 them to develop and apply the criteria
 locally in a timely fashion, while at the
 same time establishing an expeditious
 deadline.

 c. Designate Physically Interconnected
 Small MS4s

  In addition to applying criteria on a
 local basis for potential designation, the
 NPDES permitting authority must
 designate any MS4 that contributes
 substantially to the pollutant loadings of
 a physically interconnected municipal
 separate storm sewer that is regulated by
 the NPDES program for storm water
 discharges (see § 123.35(b)(4)). To be
 "physically interconnected," the MS4 of
 one entity, including roads with
 drainage systems and municipal streets,
 is physically  connected directly to the
 municipal  separate storm sewer of
 another entity. This provision applies to
 all MS4s located outside of an
 urbanized area. EPA added this section
 in recognition of the concerns of local
 government stakeholders that a local
 government should not have to shoulder
 total responsibility for a storm water
 program when storm water discharges
 from another  MS4 are also contributing
 pollutants or  adversely affecting water
 quality. This provision also helps to
 provide some consistency among MS4
programs and to facilitate watershed
 planning in the implementation of the
NPDES storm water program. EPA
recommended physical
interconnectedness in the existing
NPDES storm water regulations as a
  factor for consideration in the
  designation of additional sources.
   Today's final rule does not include
  interim deadlines for identifying
  physically interconnected MS4s.
  However, consistent with the deadlines
  identified in § 123.35(b)(3) of today's
  final rule, EPA encourages the
  permitting authority to make these
  determinations within 3 years from the
  date of publication of the final rule or
  within 5 years if the permitting
  authority is implementing a
  comprehensive watershed plan.
  Alternatively, the affected jurisdiction
  could use the petition process under 40
  CFR 122.26(f) in seeking to have the
  permitting authority designate the
  contributing jurisdiction.
   Several commenters expressed
  concerns about who could be designated
  under this provision (§ 123.35(b)(4)).
  One commenter requested that the word
  "substantially" be deleted from the rule
 because they believe any MS4 that
 contributes at all to a physically
 interconnected municipal separate
 storm sewer  should be regulated. EPA
 believes that the word "substantially"
 provides necessary flexibility to the
 permitting authorities. The permitting
 authority can decide if an MS4 is
 contributing  discharges to another
 municipal separate storm sewer in a
 manner that requires regulation. If the
 operator of a regulated municipal
 separate storm sewer believes that some
 of its pollutant loadings are coming
 from an unregulated MS4, it can
 petition the permitting authority to
 designate the unregulated MS4 for
 regulation.

 d. Respond to Public Petitions for
 Designation
  Today's final rule reiterates the
 existing opportunity for the public to
 petition the permitting authority for
 designation of a point source to be
 regulated to protect water quality. The
 petition opportunity also appears in
 existing NPDES regulations at 40 CFR
 122.26(fJ. Any person may petition the
 permitting authority to require an
 NPDES permit for a discharge composed
 entirely of storm water that contributes
 to a violation of a water quality standard
 or is a significant contributor of
 pollutants to the waters of the United
 States (see § 123.32(b)). The NPDES
 permitting authority must make a final
 determination on any petition within
 180 days after receiving the petition (see
 § 123.35(c)). EPA believes that a 180 day
 limit balances the public's need for a
timely final determination with the
NPDES permitting authority's need to
prioritize its workload. If an NPDES-
approved State or Tribe fails to act

-------
68746    Federal Register/Vol. 64, No.  235/Wednesday,  December 8, 1999/Rules and Regulations
within the 180-day timeframe, EPA may
make a determination on the petition.
EPA believes that public involvement is
an important component of the NPDES
program for storm water and feels that
this provision encourages public
participation. Section ILK, Public
Involvement/Public Role, further
discusses this topic.

3. Provide Waivers
  Today's rule provides two
opportunities for the NPDES permitting
authority to exempt certain small MS4s
from the need for a permit based on
water quality considerations. See
§§ 122.32(d) and (e). The two waiver
opportunities have different size
thresholds and take different
approaches to considering the water
quality impacts of discharges from the
MS4.
  In the proposal, EPA requested
comment on the option of waiving
coverage for all MS4s with less than
1,000 people unless the permitting
authority determined that the small
MS4 should be  regulated based on
significant adverse water quality
impacts. A number of commenters
supported this option. They expressed
concern that compliance with the rule
requirements and certification of one of
the waiver provisions were both costly
for very small communities. They stated
that the permitting authority should
identify a water quality problem before
requiring compliance. Today's rule
essentially adopts this alternative
approach for MS4s serving a population
under 1,000.
  The final rule has expanded the
waiver provision that EPA proposed for
small MS4s with a population less than
1,000. The proposed rule would have
required a small MS4 operator to certify
that storm water controls are not needed
based on either wasteload allocations
that are part of TMDLs that address the
pollutants of concern, or a
comprehensive watershed plan
implemented for the waterbody that
includes the equivalents of TMDLs and
addresses the pollutant(s) of concern.
Gommenters noted that the proposed
waivers would be unattainable if a
TMDL or equivalent analysis was
required for every pollutant that could
possibly be present in any amount in
discharges from an MS4 regardless of
whether the pollutant is causing water
quality impairment. Commenters asked
that EPA identify what constitutes the
"pollutant(s) of concern" for which a
TMDL or its equivalent must be
developed. For example, § 122.30(c)
indicates that the MS4 program is
intended to control "sediment,
suspended solids, nutrients, heavy
metals, pathogens, toxins, oxygen-
demanding substances, and floatables."
Commenters asked whether TMDLs or
equivalent analyses have to address all
of these.
  EPA has revised the proposed waiver
in response to these concerns. Under
today's rule, NPDES permitting
authorities may waive the requirements
of today's rule for any-small MS4 with
a population less than 1,000 that does
not contribute substantially to the
pollutant loadings of a physically
interconnected MS4, unless the small
MS4 discharges pollutants that have
been identified as a cause of impairment
of the waters to which the small MS4
discharges. If the small MS4 does
discharge pollutants that have been
identified as impairing the water body
into which the small MS4 discharges,
the NPDES permitting authority may
grant a waiver only if it determines that
storm water controls are not needed
based on an EPA approved or
established TMDL that addresses the
pollutant(s) of concern.
  Unlike the proposed rule, § 122.32(d)
does not allow the waiver for MS4s
serving a population under 1,000 to be
based on "the equivalent of a TMDL."
Because § 122.32(d) requires a pollutant
specific analysis only for a pollutant
that has been identified as a cause of
impairment, a TMDL  is required for
such pollutant before the waiver may be
granted. Once a pollutant has been
identified as the cause of impairment of
a water body, the State should develop
a TMDL for that pollutant for that water
body. Thus, § 122.32(d) takes a different
approach than that taken for the waiver
in § 122.32(e) for MS4s serving a
population under 10,000, which can be
based upon an analysis that is "the
equivalent of a TMDL." This is because
§ 122.32(d) requires an analysis to
support the waiver for MS4s under
1,000 only if a waterbody to which the
MS4 discharges has been identified as
impaired. The § 122.32(e) waiver, on the
other hand, would be available for larger
MS4s but only after the State
affirmatively establishes lack of
impairment based upon a
comprehensive analysis of smaller
urban waters that might not otherwise
be evaluated for the purposes of CWA
section 303. Since § 122.32(e) requires
the analysis of waters that have not been
identified as impaired, an actual TMDL
is not required and an analysis that is
the equivalent of a TMDL can suffice to
support the waiver.
  Where a State is the NPDES
permitting authority,  the permitting
authority is responsible for the
development of the TMDLs as well as
the assessment of the extent to which a
small MS4's discharge contributes
pollutants to a neighboring regulated
system. In States where EPA is the
permitting authority, EPA will use a
State's TMDLs to determine whether
storm water controls are required for the
small MS4s.
  The proposed rule would have
required the operator of the small MS4
serving a population under 1,000 to
certify that its discharge was covered
under a TMDL that indicated that
discharges from its particular system
were not having an adverse impact on
water quality (i.e., it was either not
assigned wasteload allocations under
TMDLs or its discharge is within an
assigned allocation). Many commenters
expressed concerns that MS4 operators
serving less than 1,000 persons may lack
the technical capacity to certify that
their discharges are not contributing to
adverse water quality impacts. These
commenters thought that the permitting
authority should make such a
certification. Today's rule provides
flexibility as to how the waiver is
administered. Permitting authorities are
ultimately responsible for granting the
waiver, but are free to determine
whether or not to require small MS4
operators that are seeking waivers to
submit information or a written
certification.
  Under § 122.32(e) a State may  grant a
waiver to an MS4 serving a population
between 1,000 and 10,000 only if the
State has made a comprehensive effort
to ensure that the MS4 will not cause or
contribute to water quality impairment.
To grant a § 122.32(e) waiver, the
NPDES permitting authority must
evaluate all waters of the U.S.  that
receive a discharge from the MS4 and
determine that storm water controls are
not needed. The permitting authority's
evaluation must be based on wasteload
allocations that are part of an EPA
approved or established TMDL or, if a
TMDL has not been developed or
approved, an equivalent analysis that
determines sources and allocations for
the pollutant(s) of concern. The
pollutants of concern that the  permitting
authority must evaluate include
biochemical oxygen demand (BOD),
sediment or a parameter that addresses
sediment (such as total suspended
solids, turbidity or siltation), pathogens,
oil and grease, and any other pollutant
that has been identified as a cause of
impairment of any water body that will
receive a discharge from the MS4.
Finally, the permitting authority must
have determined that future discharges
from the MS4 do not have the potential
to result in exceedances of water quality
standards, including impairment of
designated uses, or other significant

-------
            Federal Register/Vol. 64, No. 235/Wednesday, December 8, 1999/Rules  and Regulations    68747
 water quality impacts, including habitat
 and biological impacts.
   Although EPA did not propose this
 specific approach, the Agency did
 request comment on whether to increase
 the proposed 1,000 population
 threshold for a waiver. The § 122.32(e)
 waiver was developed in response to
 comments, including States' concerns
 that they needed greater flexibility to
 focus their efforts on MS4s that were
 causing water quality impairment.
 Several commenters thought that the
 threshold should be increased from
 1,000 to 5,000 or 10,000. Others
 suggested additional ways of qualifying
 for a waiver for MS4s that discharge to
 waters that are not covered by a TMDL
 or watershed plan. EPA carefully
 considered all the options for expanding
 the waiver provisions and has decided
 to expand the waiver only in the very
 narrow circumstances described above
 where a comprehensive analysis has
 been undertaken to demonstrate that the
 MS4 is not causing water quality
 impairment.
   The NPDES permitting authority can,
 at any time, mandate compliance with
 program requirements from a previously
 waived small MS4 if circumstances
 change. For example, a waiver can be
 withdrawn in circumstances where the
 permitting authority later determines
 that a waived small MS4's storm water
 discharge to a small stream will cause
 adverse impacts to water quality or
 significantly interfere with attainment of
 water quality standards. A "change in
 circumstances" could involve receipt of
 new information. Changed
 circumstances can also allow a
 regulated small MS4 operator to request
 a waiver at any time.
   Some commenters expressed concerns
 about allowing any small MS4 waivers.
 One commenter stated that storm water
 pollution prevention plans are
 necessary to control storm water
 pollution and should be required from
 all regulated small MS4s. For the
 reasons stated in the Background
 section above, EPA agrees that the
 discharges from most MS4s in
 urbanized areas should be addressed by
 a storm water management program
 outlined in today's rule. For MS4s
 serving very small areas, however, the
 TMDL development process provides an
 opportunity to determine whether an
 MS4 serving a population less than
 1,000 is having a negative impact on any
 receiving water that is impaired by a
 pollutant that the MS4 discharges. MS4s
 serving populations up to 10,000 may
receive a waiver only if a
comprehensive analysis of its impact on
receiving water has been performed.
   Other commenters said that waivers
 should not be allowed for small MS4s
 that discharge into another regulated
 MS4. These commenters stated that the
 word "substantially" should be
 removed from § 122.32(d)(i) so that a
 waiver would not be allowed for any
 system "contributing to the storm water
 pollutant loadings of a physically
 interconnected regulated MS4." As
 previously mentioned under the
 designation discussion of section
 II.G.2.C, EPA believes that the word
 "substantially" provides needed
 flexibility to the permitting authorities.
 It is important to note that this is only
 one aspect that the permitting authority
 must consider when deciding on the
 appropriateness of a waiver.

 4. Issue Permits

   NPDES permitting authorities have a
 number of responsibilities  regarding the
 permit process. Sections 123.35(d)
 through (g) ensure a certain level of
 consistency for permits, yet provide
 numerous opportunities for flexibility.
 NPDES permitting authorities must
 issue NPDES permits to cover municipal
 sources to be regulated under § 122.32,
 unless waived under § 122.32(c). EPA
 encourages permitting authorities to use
 general permits as the vehicle for
 permitting and regulating small MS4s.
 The Agency notes, however, that some
 operators may wish to take advantage of
 the option to join as a co-permittee with
 an MS4 regulated under the existing
 NPDES storm water program.
  Today's final rule includes a
 provision, § 123.35(f), that requires
 NPDES  permitting authorities to either
 include the requirements in § 122.34 for
 NPDES  permits issued for regulated
 small MS4s or to develop permit limits
 based on a permit application submitted
 by a small MS4. See Section II.H.S.a,
 Minimum Control Measures,  for  more
 details on the actual § 122.34
 requirements. See Section II.H.3.C for
 alternative and joint permitting options.
  In an attempt to avoid duplication of
 effort, § 122.34(c) allows NPDES
 permitting authorities to include permit
 conditions that direct an MS4 to  meet
 the requirements of a qualifying local,
Tribal, or State municipal storm water
 management program. For a local,
Tribal, or State program to "qualify," it
must impose, at a minimum, the
relevant requirements of § 122.34(b). A
regulated small MS4 must still follow
the procedural requirements for an
NPDES permit (i.e., submit an
application, either an individual
application or an NOI under a general
permit) but will instead follow the
substantive pollutant control
 requirements of the qualifying local,
 Tribal, or State program.
   Under § 122.35(b), NPDES permitting
 authorities may also recognize existing
 responsibilities among governmental
 entities for the minimum control
 measures in an NPDES small MS4 storm
 water permit. For example, the permit
 might acknowledge the existence of a
 State administered program that
 addresses construction site runoff and
 require that the municipalities only
 develop substantive controls for the
 remaining minimum control measures.
 By acknowledging existing programs,
 this provision is meant to reduce the
 duplication of efforts and to increase the
 flexibility of the NPDES storm water
 program.
   Section 123.35(e) of today's final rule
 requires permitting authorities to
 specify a time period of up to  5 years
 from the issuance date of an NPDES
 permit for regulated small  MS4
 operators to fully develop and
 implement their storm water programs.
 As discussed more fully below,
 permitting authorities should be
 providing extensive support to the local
 governments to assist them in
 developing and implementing their
 programs.
   In the proposed rule, EPA stated that
 the permitting authority would develop
 the menu of BMPs and if they failed to
 do so, EPA would develop the menu.
 Commenters felt that EPA should
 develop a menu of BMPs, rather than
 just providing guidance. In the
 settlement agreement for seeking an
 extension to the deadline for issuing
 today's rule, EPA committed to
 developing a menu of BMPs by October
 27, 2000. Permitting authorities can
 adopt EPA's menu or develop  their own.
 The menu itself is not intended to
 replace more comprehensive BMP
 guidance materials. As part of the tool
 box efforts, EPA will provide separate
 guidance documents that discuss the
 results from EPA-sponsored nationwide
 studies on the design, operation and
 maintenance of BMPs. Additionally,
 EPA expects that the new rulemaking on
 construction BMPs may provide more
 specific design, operation and
 maintenance criteria.

 5. Support and Oversee the Local
 Programs
  NPDES permitting authorities are
 responsible for supporting  and
 overseeing the local municipal
 programs. Section 123.35(h) of today's
 final rule highlights issues  associated
with these responsibilities.
  To the extent possible, NPDES
permitting authorities should provide
financial assistance to MS4s, which

-------
68748    Federal Register/VoI.  64,  No. 235/Wednesday, December 8, 1999/Rules and  Regulations
 often have limited resources, for the
 development and implementation of
 local programs. EPA recognizes that
 funding for programs at the State and
 Tribal levels may also be limited, but
 strongly encourages States and Tribes to
 provide whatever assistance is possible.
 In lieu of actual dollars, NPDES
 permitting authorities can provide cost-
 cutting assistance in a number of ways.
 For example, NPDES permitting
 authorities can develop outreach
 materials for MS4s to distribute or the
 NPDES permitting authority can
 actually distribute the materials.
 Another option is to implement an
 erosion and sediment control program
 across an entire State (or Tribal land),
 thus alleviating the need for the MS4 to
 implement its own program. The
 NPDES permitting authority must
 balance the need for site-specific
 controls, which are best handled by a
 local MS4, with its ability to offer
 financial assistance. EPA, States, Tribes,
 and MS4s should work as a team in
 making these kinds of decisions.
  NPDES permitting authorities are
 responsible for overseeing the local
 programs. Permitting authorities should
 work with the regulated community and
 other stakeholders to assist in local
 program development and
 implementation. This might include
 sharing information, analyzing reports,
 and taking enforcement actions, as
 necessary. NPDES permitting authorities
 play a vital role in supporting local
 programs by providing technical and
 programmatic assistance, conducting
 research projects, and monitoring
 watersheds. The NPDES permitting
 authority can also assist the MS4
 permittee in obtaining adequate legal
 authority at the local level in order to
 implement the local component of the
 CWA section 402(p)(6) program.
  NPDES permitting authorities are
 encouraged to coordinate and utilize the
 data collected  under several programs.
 States and Tribes address point and
 nonpoint source storm water discharges
 through a variety of programs. In
 developing programs to carry out CWA
 section 402(p)(6), EPA recommends that
 States and Tribes coordinate all of their
water pollution evaluation and control
programs, including the continuing
planning process under CWA section
 303(e), the existing NPDES program, the
 CZARA program, and nonpoint source
pollution control programs.
  In addition,  NPDES permitting
authorities are encouraged to provide a
brief (e.g., two-page) reporting format to
 facilitate compilation and analysis of
 data from reports submitted under
 § 122.34(g)(3).  EPA intends to develop a
model form for this purpose.
 H. Municipal Role
 1. Scope of Today's Rule
  Today's final rule attempts to
 establish an equitable and
 comprehensive four-pronged approach
 for the designation of municipal
 sources. First, the approach defines for
 automatic coverage the municipal
 systems believed to be of highest threat
 to water quality. Second, the approach
 designates municipal systems that meet
 a set of objective criteria used to
 measure the potential for water quality
 impacts. Third, the approach designates
 on a case-by-case basis municipal
 systems that "contribute substantially to
 the pollutant loadings of a physically-
 interconnected [regulated] MS4."
 Finally, the approach designates on a
 case-by-case basis, upon petition,
 municipal systems that "contribute to a
 violation of a water quality standard or
 are a significant contributor of
 pollutants."
  Today's final rule automatically
 designates for regulation small MS4s
 located in urbanized areas, and requires
 that NPDES permitting authorities
 examine for potential designation, at a
 minimum, a particular subset of small
 MS4s located outside of urbanized
 areas. Today's rule also includes
 provisions that allow for waivers from
 the otherwise applicable requirements
 for the smallest MS4s that are not
 causing impairment of a receiving water
 body. Qualifications for the waivers
 vary depending on whether the MS4
 serves a population under 1,000 or a
 population under 10,000. See
 §§ 122.32(d) and (e). These waivers are
 discussed further in section II.G.3. Any
 small MS4 automatically designated by
 the final rule or designated by the
 permitting authority under today's final
 rule is defined as a "regulated" small
 MS4 unless it receives a waiver.
  In today's final rule, all regulated
 small MS4s must establish a storm
 water discharge control program that
 meets the requirements of six minimum
 control measures. These minimum
 control measures are public education
 and outreach on storm water impacts,
 public involvement participation, illicit
 discharge detection and elimination,
 construction site storm water runoff
 control, post-construction storm water
 management in new development and
redevelopment, and pollution
prevention/good housekeeping for
municipal operations.
  Today's rule allows for a great deal of
flexibility in how an operator of a
regulated small MS4 is authorized to
 discharge under an NPDES permit, by
providing various options for obtaining
permit coverage and satisfying the
 required minimum control measures.
 For example, the NPDES permitting
 authority can incorporate by reference
 qualifying State, Tribal, or local
 programs in an NPDES general permit
 and can recognize existing
 responsibilities among different
 governmental entities for the
 implementation of minimum control
 measures. In addition, a regulated small
 MS4 can participate in the storm water
 management program of an adjoining
 regulated MS4 and can arrange to have
 another governmental entity implement
 a minimum control measure on their
 behalf.

 2. Municipal Definitions
 a. Municipal Separate Storm Sewer
 Systems (MS4s)
   The CWA does not define the term
 "municipal separate storm sewer." EPA
 defined municipal separate storm sewer
 in the existing storm water permit
 application regulations to mean, in part,
 a conveyance or system of conveyances
 (including roads with drainage systems
 and municipal streets) that is "owned or
 operated by a State, city, town borough,
 county, parish, district, association, or
 other public body * * * designed or
 used for collecting or conveying storm
 water which is not a combined sewer
 and which is not part of a Publicly
 Owned Treatment Works as defined at
 40 CFR 122.2" (see § 122.26(b)(8)(i)).
 Section 122.26 contains definitions of
 medium and large municipal separate
 storm sewer systems but no definition of
 a municipal separate storm sewer
 system, even though the term MS4 is
 commonly used. In today's rule, EPA is
 adding a definition of municipal
 separate storm sewer system and  small
 municipal separate storm sewer system
 along with the abbreviations MS4 and
 small MS4.
  The existing municipal permit
 application regulations define
 "medium" and "large" MS4s as those
 located  in an incorporated place or
 county with a population of at least
 100,000 (medium) or 250,000 (large) as
 determined by the latest Decennial
 Census (see §§ 122.26(b)(4) and
 122.26(b)(7)). In today's final rule, these
 regulations have been revised to define
 all medium and large MS4s as those
 meeting the above population
thresholds according to the 1990
Decennial Census.
  Today's rule also corrects the titles
 and contents of Appendices F, G, H,& I
to Part 122. EPA is  adding those
 incorporated places and counties  whose
 1990 population caused them to be
 defined as a "medium" or "large" MS4.
All of these MS4s have applied for

-------
            Federal Register/Vol. 64, No.  235/Wednesday, December  8,  1999/Rules and Regulations    68749
 permit coverage so the effect of this
 change to the appendices is simply to
 make them more accurate. They will not
 need to be revised again because today's
 rule "freezes" the definition of
 "medium" and "large" MS4s at those
 that qualify based on the 1990 census.
   EPA received several comments
 supporting and opposing the proposal to
 "freeze" the definitions based on the
 1990 census. Commenters who
 disagreed with EPA's position cited the
 unfairness of municipalities that reach
 the medium or large threshold at a later
 date having fewer permitting
 requirements compared to those that
 were already at the population
 thresholds when the existing storm
 water regulations took effect. EPA
 recognizes this disparity but does not
 believe it is unfair, as explained in the
 proposed rule. The decision was based
 on the fact that the deadlines from the
 existing regulations have lapsed, and
 because the permitting authority can
 always require more1 from operators of
 MS4s serving "newly over 100,000"
 populations.
 b. Small Municipal Separate Storm
 Sewer Systems
  The proposal to today's final rule
 added "the United States" as a potential
 owner or operator of a municipal
 separate storm sewer. This addition was
 intended to address an omission from
 existing regulations and to clarify that
 federal facilities are, in fact,  covered by
 the NPDES program for municipal storm
 \vater discharges when the federal
 facility is  like other regulated MS4s.
 EPA received a comment that this
 change would cause federal facilities
 located in Phase 1 areas to be
 considered Phase 1 dischargers due to
 the definition of medium and large
 MS4s. All MS4s located in Phase \
 cities or counties  are defined as Phase
 1 medium or large MS4s. EPA believes
 that all federal facilities serve a
 population of under 100,000 and should
 be regulated as small MS4s. Therefore,
 in §122.26(a)(l6) of today's final rule,
 EPA is adding federal facilities to the
 NPDES storm water discharge control
 program by changing the proposed
 definition of small municipal separate
 storm sewer system. Paragraph (i) of this
 section restates the definition of
 municipal separate storm sewer with
 the addition of "the United States" as a
 owner or operator of a small municipal
 separate storm sewer. Paragraph (ii)
 repeats the proposed language that
states that a small MS4 is a municipal
separate storm sewer that is not medium
or large.
  Most commenters agreed that federal
facilities should be covered in the same
 way as other similar MS4s. However,
 EPA received several comments asking
 whether individual federal buildings
 such as post offices or urban offices of
 the U.S. Park Service must apply for
 coverage as regulated small MS4s. Most
 of these buildings have, at most, a
 parking lot with runoff or a storm sewer
 that connects with a municipality's
 MS4. In § 122.26(a)(16)(iii), EPA
 clarifies that the definition of small MS4
 does not include individual buildings.
 These buildings may have a municipal
 separate storm sewer but they do not
 have a "system" of conveyances. The
 minimum measures for small MS4s
 were written to apply to storm sewer
 "systems" providing storm water
 drainage service to human populations
 and not to  individual buildings. This is
 true of municipal separate storm sewers
 from State  buildings as well as from
 federal buildings.
   There will likely be situations where
 the permitting authority must decide if
 a federal or State complex should be
 regulated as a small MS4. A federal
 complex of two or three buildings could
 be treated as a single building and not
 be required to apply for coverage. In
 these situations, permitting authorities
 will have to use their best judgment as
 to the nature of the complex and its
 storm water conveyance system.
 Permitting authorities should also
 consider whether the federal or State
 complex cooperates with its
 municipality's efforts to implement
 their storm water management program.
  Along with the questions about
 individual  buildings, EPA received
 many questions about how various
 provisions  of the rule should be
 interpreted for federal and State
 facilities. EPA acknowledges that
 federal and State facilities are different
 from municipalities. EPA believes,
 however, that the minimum measures
 are flexible enough that they can be
 implemented by these facilities. As an
 example, DOD commenters  asked about
 how to interpret the term "public" for
 military installations when
 implementing the public education
 measure. EPA agrees with the suggested
 interpretation of "public" for DOD
 facilities as "the resident and employee
 population within the fence line of the
 facility."
  EPA  also received many comments
 from State departments of transportation
 (DOTs] that suggested the ways in
which  they are different from
municipalities and should therefore be
regulated differently. Storm water
 discharges from State DOTs in Phase 1
areas should already be regulated under
Phase I. The preamble to Phase 1 clearly
states that "all systems within a
 geographical area including highways
 and flood control districts will be
 covered." Many permitting authorities
 regulated State DOTs as co-permittees
 with the Phase 1 municipality in which
 the highway is located. State DOTs that
 are already regulated under Phase I are
 not required to comply with Phase II.
 State DOTs that are not already
 regulated have various options for
 meeting the requirements of today's
 rule. These options are discussed in
 Section H.H.3.c.iv below. Several DOTs
 commented that some of the minimum
 measures are outside the scope of their
 mission or that they do not have the
 legal authority required for
 implementation. EPA believes that the
 flexibility of the minimum measures
 allows them to be implemented by most
 MS4s, including DOTs. When a DOT
 does not have the necessary legal
 authority, EPA encourages the DOT to
 coordinate their storm water
 management efforts with the
 surrounding municipalities and other
 State agencies. Under today's rule,
 DOTs can use any of the options of
 § 122.35 to share their storm water
 management responsibilities. DOTs may
 also want to work with their permitting
 authority to develop a State-wide DOT
 storm water permit.
  There are many storm water
 discharges from State DOTs and other
 State MS4s located in Phase 1 areas that
 were not regulated under Phase 1.
 Today's rule adds many more State
 facilities as well as all federal facilities
 located in urbanized areas. All of these
 State and federal facilities that fit the
 definition of a small MS4 must be
 covered by a storm water management
 program. The individual permitting
 authorities must decide what type of
 permit is most applicable.
  The existing NPDES storm water
 program already regulates storm water
 from federally or State-operated
 industrial sources. Federal or State
 facilities that are currently regulated
 due to their industrial discharges may
 already be implementing some of
 today's rule requirements.
  EPA received comments that
 questioned the apparent inconsistency
 between regulating a federal facility
 such as a hospital and not regulating a
 similar private facility. Normally, this
 type of private facility is regulated by
 the MS4. EPA believes that federal
 facilities are subject to local water
 quality regulations, including storm
water requirements, by virtue of the
waiver of sovereign immunity in CWA
 section 313. However, there are special
problems faced by MS4s in their efforts
to regulate federal facilities that have
not been encountered in regulating

-------
  68750    Federal Register/Vol.  64.  No. 235/Wednesday. December 8, 1999/Rules  and Regulations
  similar private facilities. To ensure
  comprehensive coverage, today's rule
  merely clarifies the need for permit
  coverage for these federal facilities.
    /. Combined Sewer Systems (CSS).
  The definition of small MS4s does not
  include combined sewer systems. A
  combined sewer system is a wastewater
  collection system that conveys sanitary
  wastewater and storm water through a
  single set of pipes to a publicly-owned
  treatment works (POTW) for treatment
  before discharging to a receiving
  waterbody. During wet weather events
  when the capacity of the combined
  sewer system is exceeded, the system is
  designed to discharge prior to the
  POTW treatment plant directly into a
  receiving waterbody. Such an overflow
  is a combined sewer overflow or CSO.
  Combined sewer systems are not subject
  to existing regulations for municipal
  storm water discharges, nor will they be
  subject to today's regulations. EPA
  addresses combined sewer systems and
  CSOs in the National Combined Sewer
  Overflow (CSO) Control Policy issued
  on April 19, 1994 (59 FR 18688). The
  CSO Control Policy  contains provisions
  for developing appropriate, site-specific
 NPDES permit requirements for
 combined sewer systems. CSO
 discharges are subject to limitations
 based on the best available technology
 economically achievable for toxic
 pollutants and based on the best
 conventional pollutant control
 technology for conventional pollutants.
 MS4s are subject to a different
 technology standard for all pollutants,
 specifically to reduce pollutants to the
 maximum extent practicable.
   Some municipalities are served by
 both separate storm sewer systems and
 combined sewer systems. If such a
 municipality is located within an
 urbanized area, only the separate storm
 sewer systems within that municipality
 is included in the NPDES storm water
 program and subject  to today's final
 rule. If the municipality is not located
 in an urbanized area, then the NPDES
 permitting authority  has discretion as to
 whether  the discharges from the
 separate  storm sewer system is subject
 to today's final rule. The NPDES
 permitting authority  will use the same
 process to designate discharges from
 portions  of an MS4 for permit coverage
 where the municipality is also served by
 a combined sewer system.
  EPA recognizes that municipalities
 that have both combined and separate
 storm sewer systems  may wish to find
ways to develop a unified program to
meet all wet weather  water pollution
control requirements more efficiently. In
the proposal to today's final rule, EPA
sought comment on ways to achieve
  such a unified program. Many
  municipalities that are served by CSSs
  and MS4s commented that it is
  inequitable to force them to comply
  with Phase II at this time because
  implementation of the CSO Control
  Policy through their NPDES permits
  already imposes a significant financial
  burden. They requested an extension of
  the implementation time frame. They
  did not provide ideas on how to unify
  the two programs. EPA encourages
  permitting authorities to work with
  these municipalities as they develop
  and begin implementation of their CSO
  and storm water management programs.
  If both sets of requirements are carefully
  coordinated early, a cost-effective wet
  weather program can be developed that
  will address both  CSO and storm  water
  requirements.
   //. Owners/Operators. Several
  commenters mentioned the difference
  between the existing storm water
  application requirement for municipal
  operators and the  proposed municipal
  requirement for owners or operators to
  apply. They felt that this inconsistency
  is confusing. The preamble to the
  existing regulations makes numerous
 references to owner/operator so there
 was no intent to make a clear distinction
 between Phase I and Phase II. Section
 122.21(b) states that when the owner
 and operator are different, the operator
 must obtain the permit. MS4s often have
 several operators. The owner may  be
 responsible for one part of the system
 and a regional authority may be
 responsible for other aspects. EPA
 proposed the "owner or operator"
 language to convey this dual
 responsibility. However, when the
 owner is responsible for some part of a
 storm water management plan, it is also
 an operator.
   EPA has revised  the regulation
 language to clarify  that  "an operator"
 must apply for a permit. When
 responsibilities for the MS4 are shared,
 all operators must apply.
 c. Regulated Small  MS4s
   In today's final rule, all small MS4s
 located in an urbanized area are
 automatically designated as "regulated"
 small MS4s provided that they were not
 previously designated into the existing
 storm water program. Unlike medium
 and large MS4s under the existing storm
 water regulations, not all small MS4s
 are designated under today's final rule.
 Therefore, today's rule distinguishes
between "small" MS4s and "regulated
small" MS4s.
  EPA's definition  of "regulated small
MS4s" in the proposal to today's rule
included mention of incorporated
places and counties. Along with the
  definition, EPA included Appendices 6
  and 7 to assist in the identification of
  areas that would probably require
  coverage as "automatically designated"
  (Appendix 6) or "potentially
  designated" (Appendix 7). The
  definition and the appendices raised
  many questions about exactly who was
  required to comply with the proposed
  requirements. Commenters raised issues
  about the definition of "incorporated
  place" and the status of towns,
  townships, and other places that are not
  considered incorporated by the Census
  Bureau. They also asked about special
  districts, regional authorities, MS4s
  already regulated, and other questions
  in order to clarify the rule's coverage.
   EPA has revised § 122.32(a) to clarify
  that discharges are regulated under
  today's rule if they are from a small MS4
  that is in an urbanized area and has not
  received a waiver or they are designated
  by the permitting authority. Today's
  rule does not regulate the county, city,
  or town. Today's rule regulates the MS4.
 Therefore, even though a county may be
 listed in Appendix 6, if that county does
 not own or operate the municipal storm
 sewer systems, the county does not have
 to submit an application or develop a
 storm water management program. If
 another entity does own or operate an
 MS4 within the county, for example, a
 regional utility district, that other entity
 needs to submit the application and
 develop the program.
   Some commenters suggested that EPA
 should change the rule language to
 specifically allow regional authorities to
 be the permitted entity and to allow
 small MS4s to apply as co-permittees.
 EPA believes that the best way to clarify
 that regional authorities can be the
 primary permitted entity is the change
 to § 122.32(a) and the explanation
 above. Because EPA assumes that
 today's regulation will be implemented
 through general permits, MS4s will not
 be co-permittees under a general permit
 in the same manner as under individual
 permits. EPA has added § 122.33(a)(4)
 and made a minor change to § 122.35(a)
 to clarify that small MS4s can work
 together to share the responsibilities of
 a storm water management program.
 This is discussed further in Section
 II.H.S.c.iv below.
  The proposed rule stated that when a
 county or Federal Indian reservation is
 only partially included in an urbanized
 area, only MS4s in the urbanized
 portion of the county or Federal Indian
 reservation would be regulated. In the
 rare  cases when an incorporated place is
 only partially included in the urbanized
 area, the entire incorporated place
would be regulated. EPA received
comments asking about towns and

-------
            Federal Register/Vol. 64, No.  235/Wednesday,  December 8, 1999/Rules and  Regulations    68751
 townships, because they were not
 considered to be incorporated areas
 according to the Census Bureau's
 definition. Would the whole town/
 township be covered or only the part of
 the town/township in the urbanized
 area? States use many different types of
 systems in their geographical divisions.
 Some towns are similar to incorporated
 cities and others are large areas that are
 more similar to counties. Some
 commenters thought that the urbanized
 area boundary was arbitrary, and if part
 of a town or county was covered, it all
 should be covered. Other commenters
 noted that some townships and counties
 encompass  very large areas of which
 only a small portion is urbanized. Due
 to the great variety of situations, EPA
 has decided that for all geographical
 entities, only MS4s in the urbanized
 area are automatically designated. The
 population  densities associated with the
 Census Bureau's designation of
 urbanized areas provide the basis for
 designation of these areas to protect
 water quality. This focused designation
 provides for consistency and allows for
 flexibility on the part of the MS4 and
 the permitting authority. In those
 situations where an incorporated place
 or a town is not all in an "urbanized
 area", there is a good possibility that it
 is served by more than one MS4. In
 those cases  where the area is served by
 the same MS4, it makes sense to
 develop a storm water program for the
 whole area. Permitting authorities may
 also decide  to designate all MS4s within
 a county or  township, if they believe it
 is necessary to protect water quality.
  Most operators of MS4s will not need
 to independently determine the status of
 coverage under today's rule. EPA has
 revised the proposed Appendices 6 and
 7 to include towns and townships.
 Therefore, these appendices will  alert
 most MS4s as to whether they are likely
 to be covered under today's rule.
 However, each permitting authority
 must make the decision as to who
 requires coverage. Most likely, an
 illustrative list of the regulated areas
 will be published with the general
 permit.  If not, the operator can contact
 its permitting authority or the Bureau of
 the Census to find out if their separate
 storm sewer systems are within an
 urbanized area.
  /. Urbanized Area Description. Under
 the Bureau of the Census definition of
 "urbanized area," adopted by EPA for
 the purposes of today's final rule, "an
 urbanized area (UA) comprises a place
 and the adjacent densely settled
surrounding territory that together have
a minimum population of 50,000
people." The proposal to today's rule
provided the full definition and case
 studies to help explain the census
 category of "urbanized area." Appendix
 2 is a simplified urbanized area
 illustration to help demonstrate the
 concept of urbanized areas in relation to
 today's final rule. The "urbanized area"
 is the shaded area that includes within
 its boundaries incorporated places, a
 portion of a Federal Indian reservation,
 portions of two counties, an entire town,
 and portions of another town. All small
 MS4s located in the shaded area are
 covered by the rule, unless and until
 waived by the permitting authority. Any
 small MS4s located outside of the
 shaded area are subject to potential
 designation by the permitting authority.
   There are 405 urbanized areas in the
 United States that cover 2 percent of
 total U.S. land area and contain
 approximately 63 percent of the nation's
 population (see Appendix 3 for a listing
 of urbanized areas of the United States
 and Puerto Rico). These numbers
 include U.S. Territories, although
 Puerto Rico is the only territory to have
 Census-designated urbanized areas.
 Urbanized areas constitute the largest
 and most dense areas of settlement. The
 purpose of determining an "urbanized
 area" is to delineate the boundaries of
 development and map the actual built-
 up urban area. The Bureau of the Census
 geographers liken it to flying over an
 urban area and drawing a line around
 the boundary of the built-up area as
 seen from the air.
   Using data from the latest decennial
 census, the Census Bureau applies the
 urbanized area definition nationwide
 (including U.S. Tribes and Territories)
 and determines which places and
 counties are included within each
 urbanized area. For each urbanized area,
 the Bureau provides full listings of who
 is included, as well as detailed maps
 and special CD-ROM files for use with
 computerized mapping systems (such as
 CIS). Each State's data center receives a
 copy of the list, and some maps,
 automatically. The States also  have the
 CD-ROM files and a variety of
 publications available to them for
 reference from the Bureau of the Census.
 In addition, local or regional planning
 agencies may have urbanized area files
 already. New listings for urbanized
 areas based on the 2000 Census will be
 available by July/August 2001, but the
 more comprehensive computer files will
 not be available until late 2001/early
 2002.
  Additional designations based on
 subsequent census years will be
governed by the Bureau of the  Census'
 definition of an urbanized area in effect
 for that year. Based on historical trends,
EPA expects that any area determined
by the Bureau of the Census to be
 included within an urbanized area as of
 the 1990 Census will not later be
 excluded from the urbanized area as of
 the 2000 Census. However, it is
 important to note that even if this
 situation were to occur, for example,
 due to a possible change in the Bureau
 of the Census' urbanized area definition,
 a small MS4 that is automatically
 designated into the NPDES program for
 storm water under an urbanized area
 calculation for any given Census year
 will remain regulated regardless of the
 results of subsequent urbanized area
 calculations.
   ii. Rationale for Using Urbanized
 Areas. EPA is using urbanized areas to
 automatically  designate regulated small
 MS4s on a nationwide basis for several
 reasons: (1) studies and data show a
 high correlation between degree of
 development/ urbanization and adverse
 impacts on receiving waters due to
 storm water (U.S. EPA, 1983; Driver et
 al., 1985; Pitt.R.E. 1991. "Biological
 Effects of Urban Runoff Discharges."
 Presented at the Engineering
 Foundation Conference: Urban Runoff
 and Receiving Systems; An
 Interdisciplinary Analysis of Impact,
 Monitoring and Management, August
 1991. Mt. Crested Butte, CO. American
 Society of Civil Engineers, New York.
 1992.; Pitt, R.E. 1995. "Biological Effects
 of Urban Runoff Discharges," in Storm

 1990. Thermal Impacts Associated with
 Urbanization and Storm water
 Management Best Management
 Practices. Prepared for the Sediment
 and Storm water Administration of the
 Maryland Department of the
 Environment.; Klein, 1979), (2) the
 blanket coverage within the urbanized
 area encourages the watershed approach
 and addresses the problem of "donut-
 holes," where unregulated areas are
 surrounded by areas currently regulated
 (storm water discharges from donut hole
 areas present a problem due to their
 contributing uncontrolled adverse
 impacts on local waters, as well as by
 frustrating the  attainment of water
 quality goals of neighboring regulated
 communities), (3) this approach targets
 present and future growth areas as a
 preventative measure to help ensure
 water quality protection, and (4) the
 determination  of urbanized areas by the
 Bureau of the Census allows operators
 of small MS4s to quickly determine
whether they are included in the NPDES
 storm water program as a regulated
small MS4.
  Urbanized areas have experienced
significant growth over the past 50
years. According to EPA calculations

-------
68752    Federal Register/Vol. 64, No.  235/Wednesday, December  8,  1999/Rules and Regulations
based on Census data from 1980 to
1990, the national average rate of growth
in the United States during that 10-year
period was more than 4 percent. For the
same period, the average growth within
urbanized areas was 15.7 percent and
the average for outside of urbanized
areas was just more than 1 percent. The
new development occurring in these
growing areas can provide some of the
best opportunities for implementing
cost-effective storm water management
controls.
  EPA received many comments on the
proposal to designate discharges based
on location within urbanized areas. EPA
considered numerous other approaches,
several of which are discussed in the
proposal to today's final rule. Several
commenters wanted designation to be
based on proven water quality problems
rather thari inclusion in an urbanized
area. One commenter proposed an
approach based on the CWA 303 (d)
listing of impaired waters and the
wasteload allocation conducted under
the TMDL process. (See section ILL. on  .
the section 303(d) and TMDL process).
The commenter's proposal would
designate small MS4s on a case-by-case
basis, covering only those discharges
where receiving streams are shown to
have water quality problems,
particularly a failure to meet water
quality standards, including designated
uses. The commenter further described
a non-NPDES approach where a State
would require cost-effective measures
based on a proportionate share under a
waste load allocation, equitably
allocated among all pollutant
contributors. These waste load
allocations would be developed with
input from all stakeholders, and
remedial measures would be
implemented in a phased manner based
on the probability of results and/or
economic feasibility. The States would
then periodically reassess the receiving
streams to determine whether the
remedial measures are working, and if
not, require additional control measures
using the same procedure used to
establish the initial measures. What the
commenter describes is almost a TMDL.
  EPA considered a remedial approach
based on water quality impairment and
rejected it for failure to prevent almost
certain degradation caused by urban
storm water. EPA's main concern in
opting  not to take a case-by-case
approach to designation was that this
approach would not provide controls for
storm water discharges in receiving
streams until after a site-specific
demonstration of adverse water quality
impact. The commenter's suggestion
would  do nothing to prevent pollution
in waters that may be meeting water
quality standards, including supporting
designated uses. The approach would
also rely on identifying storm water
management programs following
comprehensive watershed plans and
TMDL development. In most States,
water quality assessments have
traditionally been conducted for
principal mainstream rivers and their
major tributaries, not all surface waters.
The establishment of TMDLs
nationwide will take many years, and
many States will conduct additional
monitoring to determine water quality
conditions prior to establishing TMDLs.
In addition, a case-by-case approach
would not address the problem of
"donut holes" within urbanized areas
and a lack of consistency among
similarly situated municipal systems
would remain commonplace. After
careful consideration of all comments,
EPA still believes that the approach in
today's rule is the most appropriate to
protect water quality. Protection
includes prevention as well as
remediation.

d. Municipal Designation by the
Permitting Authority
  Today's final rule also allows NPDES
permitting authorities to designate MS4s
that should be included in the storm
water program as regulated small MS4s
but are not located within urbanized
areas. The final rule requires, at a
minimum, that a set of designation
criteria be applied to all small MS4s
within a jurisdiction that serves a
population of at least 10,000 and has  a
population density of at least 1,000.
Appendix 7 to this preamble provides
an illustrative list of places that the
Agency anticipates meet this criteria. In
addition, any small MS4 may be the
subject of a petition to the NPDES
permitting authority for designation. See
Section II.G, NPDES Permitting
Authority's Role for more details on the
designation and petition processes. EPA
believes that the approach of combining
nationwide and local designation to
determine municipal coverage balances
the potential for significant adverse
impacts on water quality with local
watershed protection and planning
efforts.
e. Waiving the Requirements for Small
MS4s
  Today's final rule includes  some
flexibility in the nationwide coverage of
all small MS4s located in urbanized
areas by providing the NPDES
permitting authority with the discretion
to waive the otherwise applicable
requirements of the smallest MS4s that
are not causing the impairment of a
receiving water body. Qualifications for
 the waiver vary depending on whether
 the MS4 serves a population under
 1,000 or a population between 1,000
 and 10,000. Note that even if a small
 MS4 has requirements waived, it can
 subsequently be  brought back into the
 program if circumstances change. See
 Section II.G, NPDES Permitting
 Authority's Role, for more details on
 this process.

 3. Municipal Permit Requirements
 a. Overview
   i. Summary of Permitting Options.
 Today's rule outlines six minimum
 control measures that constitute the
 framework for a  storm water discharge
 control program  for regulated small
 MS4s that, when properly implemented,
 will reduce pollutants to the maximum
 extent practicable (MEP). These six
 minimum control measures are
 specified in § 122.34(b)-and are
 discussed below in section "II.H.S.b,
 Program Requirements-Minimum
 Control Measures." All operators of
 regulated small MS4s are required to
 obtain coverage under an NPDES
 permit, unless the requirement is
 waived by the permitting authority in
 accordance with  today's rule.
 Implementation  of § 122.34(b) may be
 required either through an individual
 permit or, if the State or EPA makes one
 available to the facility, through a
 general permit. The process for issuing
 and obtaining these permits is discussed
 below in section  "II.H.S.c,  Application
 Requirements."
  As an alternative to implementing a
 program that complies with the
 requirements of § 122.34, today's  rule
 provides operators of regulated small
 MS4s with the option of applying for an
 individual  permit under § 122.26(d).
 The permit application requirements in
 § 122.26 were originally drafted to apply
 to medium and large MS4s. Although
 EPA believes that the requirements of
 § 122.34 provide  a regulatory option that
 is appropriate for most small MS4s, the
 operators of some small MS4s may
 prefer more individualized
 requirements. This alternative
 permitting option for regulated small
 MS4s that wish to develop their own
 program is  discussed below in section
 "II.H.S.c.iii. Alternative Permit Option."
 The second alternative permitting
 option for regulated small MS4s is to
 become co-permittees with a medium or
 large MS4 regulated under § 122.26(d),
 as discussed below in section
 "II.H.3.C.V. Joint  Permit Programs."
  ii. Water Quality-Based Requirements.
Any NPDES permit issued under  today's
 rule must, at a minimum, require the
 operator to develop, implement, and

-------
           Federal Register/Vol. 64, No.  235/Wednesday,  December  8, 1999/Rules and Regulations    68753
 enforce a storm water management
 program designed to reduce the
 discharge of pollutants from a regulated
 system to the MEP, to protect water
 quality, and satisfy the appropriate
 water quality requirements of the Clean
 Water Act (see MEP discussion in the
 following section). Absent evidence to
 the contrary, EPA presumes that a small
 MS4 program that implements the six
 minimum measures in today's rule does
 not require more stringent limitations to
 meet water quality standards. Proper
 implementation of the measures  will
 significantly improve water quality. As
 discussed-further below, however, small
 MS4 permittees should modify their
 programs if and when available
 information indicates that water  quality
 considerations warrant greater attention
 or prescriptiveness in specific
 components of the municipal program.
 If the program is inadequate to protect
 water quality, including water quality
 standards, then the permit will need to
 be modified to  include any more
 stringent limitations necessary to
 protect water quality.
  Regardless of the basis for the
 development of the effluent limitations
 (whether designed to implement the six
 minimum measures or more stringent or
 prescriptive limitations to protect water
 quality), EPA considers narrative
 effluent limitations requiring
 implementation of BMPs to be the most
 appropriate  form of effluent limitations
 for MS4s. CWA section 402(p)(3)(b)(iii)
 expresses a preference for narrative
 rather than numeric effluent limits, for
 example, by reference to "management
 practices, control techniques and
 system, design and engineering
 methods, and such other provisions as
 the Administrator or the State
 determines appropriate for the control
 of such pollutants." 33 U.S.C.
 1342(p)(3)(B)(iii). EPA determines that
 pollutants from wet weather discharges
 are most appropriately controlled
 through management measures rather
 than end-of-pipe numeric effluent
 limitations. As explained in the Interim
 Permitting Policy for Water Quality-
 Based Effluent Limitations in Storm
 Water Permits, issued on August  1,1996
 [61 FR 43761 (November 26,1996), EPA
believes that the currently available
 methodology for derivation of numeric
 water quality-based effluent limitations
 is significantly complicated when
applied to wet weather discharges from
MS4s (compared to continuous or
periodic batch discharges from most
other types of discharge). Wet weather
discharges from MS4s introduce a high
degree of variability in the inputs to the
models currently available for
 derivation of water quality based
 effluent limitations, including
 assumptions about instream and
 discharge flow rates, as well as effluent
 characterization. In addition, EPA
 anticipates that determining compliance
 with any such numeric limitations may
 be confounded by practical limitations
 in sample collection.
   In the first two to three rounds of
 permit issuance, EPA envisions that a
 BMP-based storm water management
 program that implements the six
 minimum measures will be the extent of
 the NPDES permit requirements for the
 large majority of regulated small MS4s.
 Because the six measures represent a
 significant level of control if properly
 implemented, EPA anticipates that a
 permit for a regulated small MS4
 operator implementing BMPs to satisfy
 the six minimum control measures will
 be sufficiently stringent to protect water
 quality, including water quality
 standards,  so that additional, more
 stringent and/or more prescriptive water
 quality based effluent limitations will be
 unnecessary.
   If a small MS4 operator implements
 the six minimum control measures in
 § 122.34(b) and the discharges are
 determined to cause or contribute to
 non-attainment of an applicable water
 quality standard, the operator needs to
 expand or better tailor its BMPs within
 the scope of the six minimum control
 measures. EPA envisions that this
 process will occur during the first two
 to three permit terms. After that period,
 EPA will revisit today's regulations for
 the municipal separate storm sewer
 program.
  If the permitting authority (rather than
 the regulated small MS4 operator) needs
 to impose additional  or more specific
 measures to protect water quality, then
 that action  will most  likely be the result
 of an assessment based on a TMDL or
 equivalent  analysis that determines
 sources  and allocations of pollutant(s) of
 concern. EPA believes that the small
 MS4's additional requirements, if any,
 should be guided by its equitable share
based on a variety of considerations,
such as cost effectiveness, proportionate
contribution of pollutants, and ability to
reasonably  achieve wasteload
reductions. Narrative effluent
limitations  in the form of BMPs may
still be the best means of achieving
those reductions.
  See Section ILL, Water Quality Issues,
for further discussion of this approach
to permitting, consistent with EPA's
interim permitting guidance. Pursuant
to CWA section 510, States
implementing their own NPDES
programs may develop more stringent or
 more prescriptive requirements than
 those in today's rule.
   EPA's interpretation of CWA section
 402(p)(3)(B)(iii) was recently reviewed
 by the Ninth Circuit in Defenders of
 Wildlife, et al v. Browner, No. 98-71080
 (September 15,1999). The Court upheld
 the Agency's action in issuing five MS4
 permits that included water quality-
 based effluent limitations. The Court
 did, however,  disagree with EPA's
 interpretation  of the relationship
 between CWA sections 301 and 402(p).
 The Court reasoned that MS4s are not
 compelled by section 301(b)(l)(C) to
 meet all State water quality standards,
 but rather that the Administrator or the
 State may rely on section
 402(p)(3)(B)(iii) to require such controls.
 Accordingly, the Defenders of Wildlife
 decision is consistent with the Agency's
 1996 "Interim  Permitting Policy for
 Water Quality-Based Effluent
 Limitations in  Storm Water Permits."
   As noted, the 1996 Policy describes
 how permits would implement an
 iterative process using BMPs,
 assessment, and refocused BMPs,
 leading toward attainment of water
 quality standards. The ultimate goal of
 the  iteration would be for water bodies
 to support their designated uses. EPA
 believes this iterative approach is
 consistent with and implements section
 301(b)(l)(C), notwithstanding the Ninth
. Circuit's interpretation. As an
 alternative to basing these water quality-
 based requirements on section
 301(b)(l)(C), however, EPA also believes
 the  iterative approach  toward
 attainment of water quality standards
 represents a reasonable interpretation of
 CWA section 402(p)(3)(B)(iii). For this
 reason, today's rule specifies that  the
 "compliance target" for the design and
 implementation of municipal storm
 water control programs is "to reduce
 pollutants to the maximum extent
 practicable (MEP), to protect water
 quality, and to satisfy the appropriate
 water quality requirements of the
 CWA." The first component, reductions
 to the MEP, would be realized through
 implementation of the six minimum
 measures. The  second  component, to
 protect water quality, reflects the overall
 design objective for municipal programs
 based on CWA section 402(p)(6). The
 third component, to implement other
 applicable water quality requirements of
 the CWA, recognizes the Agency's
 specific determination under CWA
 section 402(p)(3)(B)(iii) of the need to
 achieve reasonable further progress
 toward attainment of water quality
 standards according to the iterative BMP
 process, as well as the  determination
 that State or EPA officials who establish
 TMDLs could allocate waste loads to

-------
  68754   Federal Register/Vol. 64, No.  235/Wednesday,  December 8, 1999/Rules and Regulations
  MS4s, as they would to other point
  sources.
    EPA does not presume that water
  quality will be protected if a small MS4-
  elects not to implement all of the six
  minimum measures and instead applies
  for alternative permit limits under
  § 122.26(d). Operators of such small
  MS4s that apply for alternative permit
  limits under § 122.26(d) must supply
  additional information through
  individual permit applications so that
  the permit writer can determine
  whether the proposed program reduces
  pollutants to the MEP and whether any
  other provisions are appropriate to
  protect water quality and satisfy the
  appropriate water quality requirements
  of the Clean Water Act.
   iii. Maximum Extent Practicable.
  Maximum extent practicable (MEP) is
>  the statutory standard that establishes
  the level of pollutant reductions  that
  operators of regulated MS4s must
  achieve. The CWA requires that NPDES
  permits for discharges from MS4s "shall
  require controls to reduce the discharge
  of pollutants to the maximum extent
  practicable, including management
  practices, control techniques and
  system, design and engineering
  methods." CWA Section
  402(p)(3)(B)(iii). This section also calls
  for "such other provisions as the [EPA]
  Administrator or the State determines
  appropriate for  the control of such
  pollutants." EPA interprets this
  standard to apply to all MS4s, including
  both existing regulated (large and
  medium) MS4s, as well as the small
  MS4s regulated under today's rule.
   For regulated small MS4s under
  today's rule, authorization to discharge
  may be under either a general permit or
  individual permit, but EPA anticipates
  and expects that general permits will be
  the most common permit mechanism.
  The general permit will explain the
  steps necessary  to obtain permit
  authorization. Compliance with the
  conditions of the general permit and the
  series of steps associated with
  identification and implementation of
 the minimum control measures will
 satisfy the MEP  standard.
 Implementation of the MEP standard
 under today's rule will typically require
 the permittee to develop and implement
 appropriate BMPs to satisfy each  of the
 required six minimum control
 measures.
   In issuing the general permit, the
 NPDES permitting authority will
 establish requirements for each of the
 minimum control measures. Permits
 typically will require small MS4
 permittees to identify in their NOI the
 BMPs to be performed and to develop
 the measurable goals by which
 implementation of the BMPs can be
 assessed. Upon receipt of the NOI from
 a small MS4 operator, the NPDES
 permitting authority will have the
 opportunity to review the NOI to verify
 that the identified BMPs and
 measurable goals are consistent with the
 requirement to reduce pollutants under
 the MEP standard, to protect water
 quality, and to satisfy the appropriate
 water quality requirements of the Clean
 Water Act. If necessary, the NPDES
 permitting authority may ask the
 permittee to revise their mix of BMPs,
 for example, to better reflect the MEP
 pollution reduction requirement. Where
 the NPDES permit is not written to
 implement the minimum control
 measures specified under § 122.34(b),
 for example in the case of an individual
 permit under § 122.33(b)(2)(ii), the MEP
 standard will be applied based on the
 best professional judgment of the permit
 writer.
   Commenters argued that MEP is, as
 yet, an undefined term and that EPA
 needs to further clarify the MEP
 standards by providing a regulatory
 definition that includes recognition of
 cost considerations and technical
 feasibility. Commenters argued that,
 without a definition, the regulatory
 community is not adequately on notice
 regarding the standard with which they
 need to comply. EPA disagrees that
 affected MS4 permittees will lack notice
 of the applicable standard. The
 framework for the small MS4 permits
 described in this notice provides EPA's
 interpretation of the standard and how
 it should be applied.
   EPA has intentionally not provided a
 precise definition of MEP to allow
 maximum flexibility in MS4 permitting.
 MS4s need the flexibility to optimize
 reductions in storm water pollutants on
 a location-by-location basis. EPA
 envisions that this evaluative process
 will consider such factors as conditions
 of receiving waters, specific local
 concerns, and other aspects included in
 a comprehensive watershed plan. Other
 factors may include MS4 size, climate,
 implementation schedules, current
 ability to finance the program, beneficial
 uses of receiving water, hydrology,
 geology, and capacity to perform
 operation and maintenance.
  The pollutant reductions that
 represent MEP may be different for each
 small MS4, given the unique local
 hydrologic and geologic concerns that
may exist and the differing possible
pollutant control strategies. Therefore,
 each permittee will determine
appropriate BMPs to satisfy each of the
six minimum control measures through
an evaluative process. Permit writers
may evaluate small MS4 operator's
 proposed storm water management
 controls to determine whether reduction
 of pollutants to the MEP can be
 achieved with the identified BMPs.
   EPA envisions application of the MEP
 standard as an iterative process. MEP
 should continually adapt to current
 conditions and BMP effectiveness and
 should strive to attain water quality
 standards. Successive iterations of the
 mix of BMPs and measurable goals will
 be driven by the objective of assuring
 maintenance of water quality standards.
 If, after implementing the six minimum
 control measures there is still water
 quality impairment associated with
 discharges from the MS4, after
 successive permit terms the permittee
 will need to expand or better tailor its
 BMPs within the scope  of the six
 minimum control measures for each
 subsequent permit. EPA envisions that
 this process may take two to three
 permit terms.
   One commenter observed that MEP is
 not static and that if the six minimum
 control measures are not achieving the
 necessary water quality improvements,
 then an MS4 should be expected to
 revise and, if necessary, expand its
 program. This concept, it is argued,
 must be clearly part of the definition of
 MEP and thus incorporated into the
 binding and operative aspects of the
 rule. As is explained above, EPA
 believes that it is. The iterative process
 described above is intended to be
 sensitive to water quality concerns. EPA
 believes that today's rule contains
 provisions to implement an approach
 that is consistent with this comment.

 b. Program Requirements'Minimum
 Control Measures
  A regulated small MS4 operator must
 develop and implement a storm water
 management program designed to
 reduce the discharge of pollutants from
 their MS4 to protect water quality. The
 storm water management program must
 include the following six minimum
 measures.
  /. Public Education and Outreach on
 Storm Water Impacts. Under today's
 final rule, operators of small MS4s must
 implement a public education program
to distribute educational materials to the
community or conduct equivalent
outreach activities about the impacts of
storm water discharges on water bodies
and the steps to reduce storm water
pollution. The  public education
program should inform individuals and
households about the problem and the
steps they can take to reduce or prevent
storm water pollution.
  EPA believes that as the public gains
a greater understanding of the storm
water program,  the MS4  is likely to gain

-------
                    Federal Register/Vol.  64,  No. 235/Wednesday, December 8,  1999/Rules and Regulations    68755
          more support for the program (including
          funding initiatives). In addition,
          compliance with the program will
          probably be greater if the public
          understands the personal
          responsibilities expected of them. Well-
          informed citizens can act as formal or
          informal educators to further
          disseminate information and gather
          support for the program, thus easing the
          burden on the municipalities to perform
          all educational activities.
            MS4s are encouraged to enter into
          partnerships with their States in
          fulfilling the public education
          requirement. It may be more cost-
          effective to utilize  a State education
          program instead of numerous MS4s
          developing their own programs. MS4
          operators are also encouraged to work
          with other organizations (e.g.,
          environmental, nonprofit and industry
          organizations) that might be able to
          assist in fulfilling this requirement.
           The public education program should
          be tailored, using a mix of locally
          appropriate strategies, to target specific
          audiences and communities
          (particularly minority and
          disadvantaged communities). Examples
          of strategies include distributing
          brochures or fact sheets, sponsoring
          speaking engagements before
          community groups, providing public
          service announcements, implementing
          educational programs targeted at school
          age children, and conducting
          community-based projects such as storm
          drain stenciling, and watershed and
         beach cleanups. Operators of MS4s may
          use storm water educational information
         provided by the State, Tribe, EPA, or
          environmental, public interest, trade
          organizations, or other MS4s. Examples
         of successful public education efforts
         concerning polluted runoff can be found
         in many State nonpoint source pollution
         control programs under CWA section
         319.
           The public education program should
         inform individuals and households
         about steps they can take to reduce
         storm water pollution, such as ensuring
         proper septic system maintenance,
         ensuring the use and disposal  of
         landscape and garden chemicals
         including fertilizers and  pesticides,
         protecting and restoring riparian
         vegetation, and properly disposing of
         used motor oil or household hazardous
         wastes. Additionally, the program could
         inform individuals  and groups on how
         to become involved in local stream and
         beach restoration activities as well as
         activities coordinated by youth service
         and conservation corps and other
         citizen groups. Finally, materials or
         outreach programs should be directed
         toward targeted groups of commercial,
 industrial, and institutional entities
 likely to have significant storm water
 impacts. For example, MS4 operators
 should provide information to
 restaurants on the impact of grease
 clogging storm drains and to auto
 garages on the impacts of used oil
 discharges.
  EPA received comments from
 representatives of State DOTs and  U.S.
 Department of Defense (DOD)
 installations seeking exemption from
 the public education requirement.
 While today's rule does not exempt
 DOTs and military bases from the user
 education requirement, the Agency
 believes the flexibility inherent in  the
 Rule addresses many of the concerns
 expressed by these commenters.
  Certain DOT representatives
 commented that if their agencies were
 not exempt from the user education
 measure's requirements, they should at
 least be allowed to count DOT employee
 education as an adequate substitute.
 EPA supports the use of existing
 materials and programs, granted such
 materials and programs meet the rule's
 requirement that the MS4 user
 community (i.e., the public) is also
 educated concerning the impacts of
 storm water discharges on water bodies
 and the steps to reduce storm water
 pollution.
  Finally, certain DOD representatives
 requested that "public," as applied to
 their installations, be defined as the
 resident and employee populations
 within the fence line of the facility. EPA
 agrees that the education effort should
 be directed toward those individuals
 who frequent the federally owned land
 (i.e., residents and individuals who
 come there to work and use the MS4
 facilities).
  EPA also received a number of
 comments from municipalities stating
 that education would be more thorough
 and cost effective if accomplished by
 EPA on the national level. EPA believes
 that a collaborative State and local
 approach, in conjunction with
 significant EPA technical support,  will
 best meet the goal of targeting, and
 reaching, specific local audiences.  EPA
 technical support will include a tool
box which will contain fact sheets,
guidance documents, an information
 clearinghouse, and training and
 outreach efforts.
  Finally, EPA received comments
 expressing concern that the public
 education program simply encourages
the distribution of printed material. EPA
 is sensitive to this concern. Upon
evaluation, the Agency made changes to
the proposal's language for today's  rule.
The language has been changed to
reflect EPA's belief that a successful
 program is one that includes a variety of
 strategies locally designed to reach
 specific audiences.
   ii. Public Involvement/Participation.
 Public involvement is an integral part of
 the small MS4 storm water program.
 Accordingly, today's final rule requires
 that the municipal storm water
 management program must comply with
 applicable State and local public notice
 requirements. Section 122.34(b)(2)
 recommends a public participation
 process with efforts to reach out and
 engage all economic and ethnic groups.
 EPA believes there are two important
 reasons why the public should be
 allowed and encouraged to provide
 valuable input and assistance to the
 MS4's program.
   First, early and frequent public
 involvement can shorten
 implementation schedules and broaden
 public support for a program.
 Opportunities for members of the public
 to participate in program development
 and implementation could include
 serving as citizen representatives on a
 local storm water management panel,
 attending public hearings, working as
 citizen volunteers to educate other
 individuals about the program, assisting
 in program coordination with other pre-
 existing programs, or participating in
 volunteer monitoring efforts. Moreover,
 members of the public may be less
 likely to raise legal challenges to a
 MS4's storm water program if they have
 been involved in the decision making
 process and program development and,
 therefore, internalize personal
 responsibility for the program
 themselves.
  Second, public participation is likely
 to ensure a more successful storm water
 program by providing valuable expertise
 and a conduit to other programs and
 governments. This is particularly
 important if the MS4's storm water
 program is to be implemented on a
 watershed basis. Interested stakeholders
 may offer to volunteer in the
 implementation of all aspects of the
 program, thus conserving limited
 municipal resources.
  EPA recognizes that there are a
 number of challenges associated with
 public involvement. One challenge is in
 engaging people in the public meeting
 and program design process. Another
 challenge is addressing conflicting
 viewpoints. Nevertheless, EPA strongly
believes that these challenges can be
addressed by use of an aggressive and
 inclusive program. Section U.K.
provides further discussion on public
involvement.
  A number of municipalities sought
clarification from EPA concerning what
the public participation program must
_

-------
68756    Federal Register/Vol. 64, No. 235/Wednesday, December 8, 1999/Rules and Regulations
actually include. In response, the actual
requirements are minimal, but the
Agency's recommendations are more
comprehensive. The public
participation program must only comply
with applicable State and local public
notice requirements. The remainder of
the preamble, as well as the Explanatory
Note accompanying the regulatory text,
provide guidance to the MS4s
concerning what elements a successful
and inclusive program should include.
EPA will provide technical support as
part of the tool box (i.e., providing
model public involvement programs,
conducting public workshops, etc.) to
assist MS4 operators meet the intent of
this measure.
  Finally, the Agency encourages MS4s
to seek public participation prior to
submitting an NOI. For example, public
participation at this stage will allow the
MS4 to involve the public in developing
the BMPs and measurable goals for their
NOI.
  Hi. Illicit Discharge Detection and
Elimination. Discharges from small
MS4s often include wastes and
wastewater from non-storm water
"illicit" discharges. Illicit discharge is
defined at 40 CFR 122.26(b)(2) as any
discharge to a municipal separate storm
sewer that is  not composed entirely of
storm water, except discharges pursuant
to an NPDES permit and discharges
resulting from fire fighting activities. As
detailed below, other sources of non-
storm water, that would otherwise be
considered illicit discharges, do not
need to be addressed unless the operator
of the MS4 identifies one or more of
them as a significant source of
pollutants into the system. EPA's
Nationwide Urban Runoff Program
(NURP) indicated that many storm
water outfalls still discharge during
substantial dry periods. Pollutant levels
in these dry weather flows were shown
to be high enough to significantly
degrade receiving water quality. Results
from a 1987 study conducted in
Sacramento, California, revealed that
slightly less than one-half of the water
discharged from a municipal separate
storm sewer system was not directly
attributable to precipitation runoff (U.S.
Environmental Protection Agency,
Office of Research and Development.
1993. Investigation of Inappropriate
Pollutant Entries Into Storm Drainage
Systems—A User's Guide. Washington,
DC EPA 600/R-92/238.) A significant
portion of these dry weather flows
results from illicit and/or inappropriate
discharges and connections to the
municipal separate storm sewer system.
Illicit discharges enter the system
through either direct connections (e.g.,
wastewater piping either mistakenly or
deliberately connected to the storm
drains) or indirect connections (e.g.,
infiltration into the storm drain system
or spills collected by drain inlets).
  Under the existing NPDES program
for storm water, permit applications for
large and medium MS4s are to include
a program description for effective
prohibition against non-storm water
discharges into their storm sewers (see
40 CFR 122.26 (d)(l)(v)(B) and
(d)(l)(iv)(B)). Further, EPA believes that
in implementing municipal storm water
management plans under these permits,
large and medium MS4 operators
generally found their illicit discharge
detection and elimination programs to
be cost-effective. Properly implemented
programs also significantly improved
water quality.
  In today's rule, any NPDES permit
issued to an operator of a regulated
small MS4  must, at a minimum, require
the operator to develop, implement and
enforce an illicit discharge detection
and elimination program. Inclusion of
this measure for regulated small MS4s is
consistent with the "effective
prohibition" requirement for large and
medium MS4s. Under today's rule, the
NPDES permit will require the operator
of a regulated small MS4 to: (1) Develop
(if not already completed) a storm sewer
system map showing the location of all
outfalls, and names and location of all
waters of the United States that receive
discharges from those outfalls; (2) to the
extent allowable under State, Tribal, or
local law, effectively prohibit through
ordinance,  or other regulatory
mechanism, illicit discharges into the
separate storm sewer system and
implement appropriate enforcement
procedures and actions as needed; (3)
develop and implement a plan to detect
and address illicit discharges, including
illegal dumping, to the system; and  (4)
inform public employees, businesses,
and the general public of hazards
associated with illegal discharges and
improper disposal of waste.
  The illicit discharge and elimination
program need only address the
following categories of non-storm water
discharges if the operator of the small
MS4 identifies them as significant
contributors of pollutants to its small
MS4:  water line flushing, landscape
irrigation, diverted stream flows, rising
ground waters, uncontaminated ground
water infiltration (as defined at 40 CFR
35.2005(20)), uncontaminated pumped
ground water, discharges from potable
water sources, foundation drains, air
conditioning condensation, irrigation
water, springs, water from crawl space
pumps, footing drains, lawn watering,
individual residential car washing,
flows from riparian habitats and
wetlands, dechlorinated swimming pool
discharges, and street wash water
(discharges or flows from fire fighting
activities are excluded from the
definition of illicit discharge and only
need to be addressed where they are
identified as significant sources of
pollutants to waters of the United
States). If the operator of the MS4
identifies one or more of these
categories of sources to be a significant
contributor of pollutants to  the system,
it could require specific controls for that
category of discharge or prohibit the
discharges completely.
  Several comments were received on
the mapping requirements of the
proposal. Most comments said that more
flexibility should be given to the MS4s
to determine their mapping needs, and
that resources could be better spent in
addressing problems once the illicit
discharges are detected. EPA reviewed
the mapping requirements in the
proposed rule and agrees that some of
the information is not necessary in order
to begin an illicit discharge  detection
and elimination program. Today's rule
requires a map or set of maps that show
the locations of all outfalls and names
and locations of receiving waters.
Knowing the locations of outfalls and
receiving waters are necessary to be able
to conduct dry weather field screening
for non-storm water flows and to
respond to illicit discharge reports from
the public. EPA recommends that the
operator collect any existing
information on outfall locations (e.g.,
review city records, drainage maps,
storm drain maps), and then conduct
field surveys to verify the locations. It
will probably be necessary to "walk"
(i.e. wade small receiving waters or use
a boat for larger receiving waters) the •
streambanks and shorelines, and it may
take more than one trip to locate all
outfalls. A coding system should be
used to mark and identify each outfall.
MS4 operators have the flexibility to
determine the type (e.g. topographic,
CIS, hand or computer drafted) and size
of maps which best meet their needs.
The map scale should be such that the
outfalls can be accurately located. Once
an illicit discharge is detected at an
outfall, it may be necessary  to map that
portion of the storm sewer system
leading to the outfall in order to locate
the source of the discharge.
  Several comments requested
clarification of the requirement to
develop and implement a plan to detect
and eliminate illicit discharges. EPA
recommends that plans include
procedures for the following: locating
priority areas; tracing the source of an
illicit discharge; removing the source of
the discharge; and program  evaluation

-------
                     Federal Register/Vol. 64, No. 235/Wednesday, December 8,  1999/Rules and Regulations    68757
          and assessment. EPA recommends that
          MS4 operators identify priority areas
          (/.e., problems areas) for more detailed
          screening of their system based on
          higher likelihood of illicit connections
          (e.g., areas with older sanitary sewer
          lines), or by conducting ambient
          sampling to locate impacted reaches.
          Once priority areas are identified, EPA
          recommends visually screening outfalls
          during dry weather and conducting field
          tests, where flow is occurring, of
          selected chemical parameters as
          indicators of the discharge source.
          EPA's manual for investigation of
          inappropriate pollutant entries into the
          storm drainage system (EPA, 1993)
          suggests the following parameter list:
          specific conductivity, fluoride and/or
          hardness concentration, ammonia and/
          or potassium concentration, surfactant
          and/or fluorescence concentration,
          chlorine concentration, pH and other
          chemicals indicative of industrial
          sources. The manual explains why each
          parameter is a good indicator and how
          the information can be used to
          determine the type of source flow. The
          Agency is not recommending that
          fluoride and chlorine, generally used to
          locate potable water discharges, be
          addressed under this program, therefore
          a short list of parameters may include
          conductivity, ammonia, surfactant and
          pH. Some MS4s have found it useful to
          measure for fecal coliform or E. coli in
          their testing program. Observations of
          physical characteristics of the discharge
          are also helpful such as flow rate,
          temperature, odor, color, turbidity,
          floatable matter, deposits and stains,
          and vegetation.
            The implementation plan should also
          include procedures for tracing the
          source of an illicit discharge. Once an
          illicit discharge is detected and field
          tests provide source characteristics, the
          next step  is to determine the actual
          location of the source. Techniques for
          tracing the discharge to its place of
          origin may include: following the flow
          up the storm drainage system via
          observations and/or chemical testing in
          manholes or in open channels;
          televising storm sewers; using infrared
          and thermal photography; conducting
          smoke or dye tests.
           The implementation plan should also
          include procedures for removing the
          source of the illicit discharge. The first
          step may be to notify the property
          owner and specify a length of time for
          eliminating the discharge. Additional
          notifications and escalating legal actions
          should also be described in this part of
          the plan.
           Finally, the implementation plan
          should include procedures for program
          evaluation and assessment. Procedures
 could include documentation of actions
 taken to locate and eliminate illicit
 discharges such as: number of outfalls
 screened, complaints received and
 corrected, feet of storm sewers televised,
 numbers of discharges and quantities of
 flow eliminated, number of dye or
 smoke tests conducted. Appropriate
 records of such actions should be  kept
 and should be submitted as part of the
 annual reports for the first permit  term,
 as specified by the permitting authority
 (reports only need to be submitted in
 years 2 and 4 in later permits). For more
 on reporting requirements, see
 §122.34(g).
  EPA received comments regarding an
 MS4's legal authority beyond its
 jurisdictional boundaries to inspect or
 take enforcement against illicit
 discharges. EPA recognizes that illicit
 flows may originate in one jurisdiction
 and cross into one or more jurisdictions
 before being discharged at an outfall. In
 such instances, EPA expects the MS4
 that detects the illicit flow to trace it to
 the point where it leaves their
 jurisdiction and notify the adjoining
 MS4 of the flow, and any other physical
 or chemical information. The adjoining
 MS4 should then trace it to the source
 or to the location where it enters their
 jurisdiction. The process of notifying
 the adjoining MS4 should continue
 until the source is located and
 eliminated. In addition, because any
 non-storm water discharge to waters of
 the U.S. through an MS4 is subject to
 the prohibition against unpermitted
 discharges pursuant to CWA section 301
 (a), remedies are available under the
 federal enforcement provisions of CWA
 sections 309 and 505.
  EPA requested and received
 comments regarding the prohibition and
 enforcement provision for this
 minimum measure. Commenters
 specifically questioned the proposal that
 the operator only has to implement the
 appropriate prohibition and
 enforcement procedures "to the extent
 allowable under State of Tribal law."
 They raised concerns that by qualifying
 prohibition and enforcement procedures
 in this manner, the operator could
 altogether ignore this minimum measure
 where affirmative legal authority did not
 exist. Comments suggested that EPA
 require States to grant authority to  those
 municipalities where it did not exist.
 Other comments, however, stated that
 municipalities cannot exercise legal
 authority not granted to them under
 State law, which varies considerably
 from one State to another. EPA has no
 intention of directing State legislatures
 on how to allocate authority and
responsibility under State law. As  noted
above, there is at least one remedy  (the
 federal CWA) to control non-storm
 water discharges through MS4s. If State
 law prevents political subdivisions from
 controlling discharges through storm
 sewers, EPA anticipates common sense
 will prevail to provide those MS4
 operators with the ability to meet the
 requirements applicable for their
 discharges.
   One comment reinforced the
 importance of public information and
 education to the success of this
 measure. EPA agrees and suggests that
 MS4 operators consider a variety of
 ways to inform and educate the public
 which could include storm drain
 stenciling; a program to promote,
 publicize, and facilitate public reporting
 of illicit connections or discharges; and
 distribution of visual and/or printed
 outreach materials. Recycling and other
 public outreach programs could be
 developed to address potential sources
 of illicit discharges, including used
 motor oil, antifreeze, pesticides,
 herbicides, and fertilizers.
   EPA received comments that State
 DOT's lack authority to implement this
 measure. EPA believes that most DOTs
 can implement most parts of this
 measure. If a DOT does not have the
 necessary legal authority to implement
 any part of this measure, EPA
 encourages them to coordinate their
 storm water management efforts with
 the surrounding MS4s and other State
 agencies. Many DOTs that are regulated
 under Phase I of this program are co-
 permittees with the local regulated MS4.
 Under today's rule, DOTs can use any
 of the options of § 122.35 to share their
 storm water management
 responsibilities.
  EPA received comments requesting
 clarification of various terms such as
 "outfall" and "illicit discharge." One
 comment asked EPA to reinforce the
 point that a "ditch" could be considered
 an outfall. The term "outfall" is defined
 at 40 CFR 122.26(b)(9) as "a point
 source at the point where a municipal
 separate storm sewer discharges to
 waters of the United States *  * *". The
 term municipal separate storm sewer is
 defined at 40 CFR § 122.26(b)(8) as "a
 conveyance or system of conveyances
 (including roads with drainage systems,
 municipal streets, catch basins, curbs,
gutters, ditches, man-made channels,  or
 storm drains) *  * *". Following the
 logic of these definitions, a "ditch" may
be part of the municipal separate storm
 sewer, and at the point where the ditch
 discharges to waters of the United
 States, it would be an outfall. As with
any determination about jurisdictional
provisions of the CWA, however, final
 decisions require case specific
evaluations of fact.
_

-------
68758   Federal Register/Vol. 64, No. 235/Wednesday, December 8, 1999/Rules  and  Regulations
  One commenter specifically requested
clarification on the relationship between
the term "illicit discharge" and non-
storm water discharges from fire
fighting. The comment suggested that it
would be impractical to attempt to
determine whether the flow from a
specific fire (i.e., during a fire) is a
significant source of pollution. EPA
intends that MS4s will address all
allowable non-storm water flows
categorically rather than individually. If
an MS4 is concerned that flows from
fire fighting are, as a category,
contributing substantial amounts of
pollutants to their system, they could
develop a program to address  those
flows prospectively. The program may
include an analysis  of the flow from
several sources, steps to minimize the
pollutant contribution, and a plan to
work with the sources of the discharge
to minimize any adverse impact on
water quality. During the development
of such a program, the MS4 may
determine that only certain types of
flows within a particular category are a
concern, for example, fire fighting flows
at industrial sites where large  quantities
of chemicals are present. In this
example, a review of existing
procedures with the fire department
and/or hazardous materials team may
reveal weaknesses or strengths
previously unknown to the MS4
operator.
  EPA received comments requesting
modifications to the rule to include on-
site sewage disposal systems (i.e., septic
systems) in the  scope of the illicit
discharge program. On-site sewage
disposal systems that flow into storm
drainage systems are within the
definition of illicit discharge as defined
by the regulations. Where they are
found to be the  source of an illicit
discharge, they  need to be eliminated
similar to any other  illicit discharge
source. Today's rule was not modified
to include discharges from on-site
sewage disposal systems specifically
because those sources are already
within the scope of the existing
definition of illicit discharge.
  iv. Construction Site Storm Water
Runoff Control. Over a short period of
time, storm water runoff from
construction site activity can contribute
more pollutants, including sediment, to
a receiving stream than had been
deposited over several decades (see
section I.E.3). Storm water runoff from
construction sites can include
pollutants other than sediment, such as
phosphorus  and nitrogen, pesticides,
petroleum derivatives, construction
chemicals, and  solid wastes that may
become mobilized when land  surfaces
are disturbed. Generally, properly
implemented and enforced construction
site ordinances effectively reduce these
pollutants. In many areas, however, the
effectiveness of ordinances in reducing
pollutants is limited due to inadequate
enforcement or incomplete compliance
with such local ordinances by
construction site operators (Paterson,
R.G. 1994. "Construction Practices: The
Good, the Bad, and the Ugly."
Watershed Protection Techniques 1(2)).
  Today's rule requires operators of
regulated small MS4s to develop,
implement, and enforce a pollutant
control program to reduce pollutants in
any storm water runoff from
construction activities that result in
land disturbance of 1 or more acres (see
§ 122.34(b)(4)). Construction  activity on
sites disturbing less than one acre must
be included in the program if the
construction activity is part of a larger
common plan of development or sale
that would disturb one acre or more.
  The construction runoff control
program of the regulated small MS4
must include an ordinance or other
regulatory mechanism to require erosion
and sediment controls to the  extent
practicable and allowable under State,
Tribal or local law. The program also
must include sanctions to ensure
compliance (for example, non-monetary
penalties, fines, bonding requirements,
and/or permit denials for non-
compliance). The program must also
include, at a minimum: requirements for
construction site operators to implement
appropriate erosion and sediment
control BMPS, such as silt fences,
temporary detention ponds and
diversions; procedures for site plan
review by the small MS4 which
incorporate consideration of potential
water quality impacts; requirements to
control other waste such as discarded
building materials, concrete truck
washout, chemicals, litter, and sanitary
waste at the construction site that may
adversely impact water quality;
procedures for receipt and consideration
of information submitted by the public
to the MS4; and procedures for site
inspection and enforcement of control
measures by the small MS4.
  Today's rule provides flexibility  for
regulated small MS4s by allowing them
to exclude from their construction
pollutant control program runoff from
those construction sites for which the
NPDES permitting authority has waived
NPDES storm water small construction
permit requirements. For example, if the
NPDES permitting authority waives
permit coverage for storm water
discharges from construction sites less
than 5 acres in areas where the rainfall
erosivity factor is  less than 5, then the
regulated small MS4 does not have to
include these sites in its storm water
management program. Even if
requirements for a discharge from a
given construction site are waived by
the NPDES permitting authority,
however, the regulated small MS4 may
still chose to control those discharges
under the MS4's construction pollutant
control program, particularly where
such discharges may cause siltation
problems in storm sewers. See Section
Il.I.l.b for more information on
construction waivers by the permitting
authority.
  Some commenters suggested that the
proposed construction minimum
measure requirements went beyond the
permit application requirements
concerning construction for medium
and large MS4s. In response, EPA has
made changes to the proposed measure
so that it more closely resembles the
MS4 permit application requirements in
existing regulations. For example, as
described below, the Agency revised the
proposed requirements for "pre-
construction review of site management
plans" to require "procedures for site
plan review."
  One commenter expressed concerns
that addressing runoff from construction
sites within urbanized areas (through
the small MS4 program)  differently from
construction sites outside urbanized
areas (which will not be  covered by the
small MS4 program) will encourage
urban sprawl. Today's rule, together
with the existing requirements, requires
all construction greater than or equal to
1 acre, unless waived, to be covered by
an NPDES permit whether it is located
inside or outside of an urbanized area
(see § 122.26(b)(15)). Today's rule does
not require small MS4s to control runoff
from construction sites more stringently
or prescriptively than is required for
construction site runoff outside
urbanized areas. Therefore, today's rule
imposes no substantively different
onsite controls on runoff of storm water
from construction sites in urbanized
areas than from construction sites
outside of urbanized areas.
  One commenter recommended that
the small MS4 construction site  storm
water runoff control program address all
storm water runoff from construction
sites, not just the runoff into the MS4.
The commenter also believed that MS4s
should provide clear, objective
standards for all construction sites. EPA
agrees. Because today's rule only
regulates discharges from the MS4, the
construction pollutant control measure
only requires small MS4 operators to
control runoff into its system. As a
practical matter, however, EPA
anticipates that MS4 operators will find
that regulation of all construction site

-------
            Federal Register/Vol. 64, No. 235/Wednesday, December 8, 1999/Rules  and Regulations    68759
  runoff, whether they runoff into the
  MS4 or not, will prove to be the most
  simple and efficient program. The
  Agency may provide more specific
  criteria for construction site BMPs in the
  forthcoming rule being developed under
  CWA section 402(m). See section II.D.l
  of today's rule.
    One commenter stated that there is no
  need for penalties at the local level by
  the small MS4 because the CWA already
  imposes sufficient penalties to ensure
  compliance. EPA disagrees and believes
  that enforcement and compliance at the
  local level is both necessary and
  preferable. Examples of sanctions, some
  not available under the CWA, include
  non-monetary penalties, monetary fines,
  bonding requirements, and  denial of
  future or other local permits.
   One commenter recommended that
  EPA should not include the requirement
  to control pollutants other than
  sediment from construction sites in this
  measure. EPA disagrees with this
  comment. The requirement is to control
 waste that "may cause adverse impacts
 on water quality." Such wastes may
 include discarded building materials,
 concrete truck washout, chemicals,
 pesticides, herbicides, litter, and
 sanitary waste. These wastes, when
 exposed to and mobilized by storm
 water, can contribute to water quality
 impairment.
   The proposed rule required
 "procedures for pre-construction review
 of site management plans." EPA
 requested comment on expanding this
 provision to require both review and
 approval of construction site storm
 \vater plans. Many commenters
 expressed the concern that review and
 approval of site plans is not only costly
 and time intensive, but may
 unnecessarily delay construction
 projects and unduly burden staff who
 administer the local program. In
 addition, some commenters expressed
 confusion whether EPA proposed pre-
 construction review for all site
 management plans or only higher
 priority sites. To address these
 comments, and be consistent with the
 permit application requirements for
 larger MS4s, EPA changed "procedures
 for pre-construction review of site
 management plans" to "procedures for
 site plan review." Today's rule requires
 the small MS4 to  develop procedures for
 site plan review so as to incorporate
 consideration of adverse potential water
 quality impacts. Procedures should
 include review of site erosion and
sediment control plans, preferably
before construction activity begins on a
site. The objective is for the small MS4
operator and the construction site
operator to address storm water runoff
  from construction activity early in the
  project design process so that potential
  consequences to the aquatic
  environment can be assessed and
  adverse water quality impacts can be
  minimized or eliminated.
   One commenter requested that EPA
  delete the requirement for "procedures
  for receipt and consideration of
  information submitted by the public"
  because it went beyond existing storm
  water requirements. Another commenter
  stated that establishing a separate
  process to respond to public inquiries
  on a project is a burden to small
  communities, especially if the project
  has gone through an environmental
  review. One commenter requested
  clarification of this provision. EPA has
  retained this requirement in today's
  final rule to require some formality in
  the process for addressing public
  inquiries regarding storm water runoff
  from construction activities. EPA does
  not intend that small MS4s develop a
 separate, burdensome process to
 respond to every public inquiry. A small
 MS4 could, for example, simply log
 public complaints on existing storm
 water runoff problems from
 construction sites and pass that
 information on to local inspectors. The
 inspectors could then investigate
 complaints based on the severity of the
 violation and/or priority area.
   One commenter believed that the
 proposed requirement of "regular
 inspections during construction" would
 require every construction project to be
 inspected more than once by the small
 MS4 during the term of a construction
 proji-ct. EPA has deleted the reference to
 "n-giilar inspections." Instead, the small
 MS4 will be required to "develop
 procedures for site inspection and
 enforcement of control measures."
 Procedures could include steps to
 identify priority sites for inspection and
 enforcement based on the nature and
 extent of the construction activity,
 topography, and the characteristics of
 soils and receiving water quality.
  In order to avoid duplication of small
 MS4 construction requirements with
 NPDES  construction permit
 requirements, today's rule adds
 § 122.44(s) to recognize that the NPDES
 permitting authority can incorporate
 qualifying State, Tribal, or local erosion
 and sediment control requirements in
 NPDES permits for construction site
 discharges. For example, a construction
 site operator who complies with MS4
 construction pollutant control programs
that are referenced in the NPDES
construction permit would satisfy the
requirements of the NPDES permit. See
section Il.I.l.d for more information on
incorporating qualifying programs by
  reference into NPDES construction
  permits. This provision has no impact
  on, or direct relation to, the small MS4
  operator's responsibilities under the
  construction site storm water runoff
  control minimum measure. Conversely,
  under § 122.35(b), the permitting
  authority may recognize in the MS4's
  permit that another governmental entity,
  or the permitting authority itself, is
  responsible for implementing one or
  more of the minimum measures
  (including construction site storm water
  runoff control), and not include this
  measure in the small MS4's permit. In
  this case, the other governmental
  entity's program must satisfy all of the
  requirements of the omitted measure.
   v. Post-Construction Storm Water
  Management in New Development and
  Redevelopment. The NURP study and
  more recent investigations indicate that
  prior planning and designing for the
  minimization of pollutants in storm
 water discharges is the most cost-
 effective approach to storm water
 quality management. Reducing
 pollutant concentrations in storm water
 after the discharge enters a storm sewer
 system is often more expensive and less
 efficient than preventing or reducing
 pollutants at the source. Increased
 human activity associated with
 development often results in increased
 pollutant loading from storm water
 discharges. If potential adverse water
 quality impacts are considered from the
 beginning stages of a project, new
 development and redevelopment
 provides more opportunities for water
 quality protection. For example,
 minimization of impervious areas,
 maintenance or restoration of natural
 infiltration, wetland protection, use of
 vegetated drainage ways, and use of
 riparian buffers have been shown to
 reduce pollutant loadings in storm
 water runoff from developed areas. EPA
 encourages operators of regulated small
 MS4s to identify specific problem areas
 within their jurisdictions and initiate
 innovative solutions and designs to
 focus attention on those areas through
 local planning.
  In today's rule at § 122.34(b)(5),
 NPDES permits issued to an operator of
 a regulated small MS4 will require the
 operator to develop, implement, and
 enforce a program to address storm
 water runoff from new development and
 redevelopment projects that result in
 land disturbance of greater than or equal
 to one acre, including projects less than
 one acre  that are part of a larger
 common plan of development or sale,
that discharge into the MS4.
 Specifically, the NPDES permit will
require the operator of a regulated small
MS4 to: (1) Develop and implement

-------
68760    Federal Register/Vol. 64, No.  235/Wednesday, December 8,  1999/Rules and Regulations
strategies which include a combination
of structural and/or non-structural best
management practices (BMPs)
appropriate for the community; (2) use •
an ordinance, or other regulatory
mechanism to address post-construction
runoff from new development and
redevelopment projects to the extent
allowable under State, Tribal or local
law; (3) ensure adequate long-term
operation and maintenance of BMPs;
and (4) ensure that controls are in place
that would minimize water quality
impacts. EPA intends the term
"redevelopment" to refer to alterations
of a property that change the "footprint"
of a site or building in such a way that
results in the disturbance of equal to or
greater than 1 acre  of land. The term is
not intended to include such activities
as exterior remodeling, which would
not be expected to  cause adverse storm
water quality impacts and offer no new
opportunity for storm water controls.
  EPA received comments requesting
guidance and clarification of the rule
requirements. The  scope of the
comments ranged from general requests
for  more details on how MS4 operators
should accomplish the four
requirements listed above, to specific
requests for information regarding
transfer of ownership for structural
controls, as well as ongoing
responsibility for operation and
maintenance. By the term
"combination" of BMPs, EPA intends a
combination of structural and/or non-
structural BMPs. For this requirement,
the term "combination" is meant to
emphasize that multiple BMPs should
be considered and  adopted for use in
the community. A  single BMP generally
cannot significantly reduce pollutant
loads because pollutants come from
many sources within a community. The
BMPs chosen should: (1) Be appropriate
for the local community; (2) minimize
water quality impacts; and (3) attempt to
maintain pre-development runoff
conditions. In choosing appropriate
BMPs, EPA encourages small MS4
operators to participate in locally-based
watershed planning efforts which
attempt to involve  a diverse group of
stakeholders. Each new development
and redevelopment project should have
a BMP component. If an approach is
chosen that primarily focuses on
regional or non-structural BMPs,
however, then the  BMPs  may be located
away from the actual development site
(e.g., a regional water quality pond).
  Non-structural BMPs are preventative
actions that involve management and
source controls such as: (1) Policies  and
ordinances that provide requirements
and standards to direct growth to
identified areas, protect sensitive areas
such as wetlands and riparian areas,
maintain and/or increase open space
(including a dedicated funding source
for open space acquisition), provide
buffers along sensitive water bodies,
minimize impervious surfaces, and
minimize disturbance of soils and
vegetation; (2)  policies or ordinances
that encourage infill development in
higher density urban areas, and areas
with existing storm sewer infrastructure;
(3) education programs for developers
and the public about project designs
that minimize water quality impacts;
and (4) other measures such as
minimization of the percentage of
impervious area after development, use
of measures to minimize directly
connected impervious areas, and source
control measures often thought of as
good housekeeping, preventive
maintenance and spill prevention.
Detailed examples of non-structural
BMPs follow.
  Preserving open space may help to
protect water quality as well as provide
other benefits such as recharging
groundwater supplies, detaining storm
water, supporting wildlife and
providing recreational opportunities.
Although securing funding for open
space acquisition may be difficult,
various funding mechanisms have been
used. New Jersey uses a portion of their
State sales tax (voter approved for a ten
year period) as a stable source of
funding to finance the preservation of
historic sites, open space and farmland.
Colorado uses part of the proceeds from
the State lottery to acquire and manage
open space. Some local municipalities
use a percentage of the local sales tax
revenue to pay for open space
acquisition (e.g., Jefferson County, CO
has had an open space program in place
since 1977 funded by a 0.50 percent
sales tax). Open space can be acquired
in the form of: fee simple purchase;
easements; development rights;
purchase and sellback or leaseback
arrangements; purchase options; private
land trusts; impact fees; and land
dedication requirements. Generally, fee
simple purchases provide the highest
level of development control and
certainty of preservation, whereas the
other forms of acquisition may provide
less control, though they would also
generally be less costly.
   Cluster development, while allowing
housing densities comparable to
conventional zoning practice,
concentrates housing units in a portion
of the total site area which provides for
greater open space, recreation, stream
protection and storm water control. This
type of development, by reducing lot
sizes, can protect sensitive areas and
result in less impervious surface, as well
as reduce the cost for roads and other
infrastructure.
  Minimizing directly connected
impervious areas (DCIAs) is a drainage
strategy that seeks to reduce paved areas
and directs storm water runoff to
landscaped areas or to structural
controls such as grass swales or buffer
strips. This strategy can slow the rate of
runoff, reduce runoff volumes,  attenuate
peak flows, and encourage filtering and
infiltration of storm water. It can be
made an integral part of drainage
planning for any development (Urban
Drainage and Flood Control District,
Denver, CO. 1992. Urban Storm
Drainage Criteria Manual, Volume 3—
Best Management Practices). The Urban
Drainage and Flood Control District
manual describes three levels for
minimizing DCIAs. At Level 1 all
impervious surfaces are made to drain
over grass-covered areas before reaching
a storm water conveyance system. Level
2 adds to Level 1 and replaces street
curb and gutter systems with low-
velocity grass-lined swales and pervious
street shoulders. In addition to Levels 1
and 2, Level 3 over-sizes swales and
configures driveway and street crossing
culverts to use grass-lined swales as
elongated detention basins.
  Structural BMPs include: (1) Storage
practices such as wet ponds and
extended-detention outlet structures; (2)
filtration practices such as grassed
swales, sand filters and filter strips; and
(3) infiltration practices such as
infiltration basins and infiltration
trenches.
  EPA recommends that small  MS4
operators ensure the appropriate
implementation of the structural BMPs
by considering some or all of the
following: (1) Pre-construction review of
BMP designs; (2) inspections during
construction to verify BMPs are built as
designed; (3) post-construction
inspection and maintenance of BMPs; -
and (4) sanctions to ensure compliance
with design, construction or operation
and maintenance (O&M) requirements
of the program.
  EPA cautions that certain infiltration
systems such as dry wells, bored wells
or tile drainage fields may be subject to
Underground Injection Control (UIC)
program requirements (see 40 CFR Part
144.12.). To find out more about these
requirements, contact your state UIC
Program, or call EPA's Safe Drinking
Water Hotline at 1-800-426-4791.
  In order to meet the third post-
construction requirement (ensuring
adequate long-term O&M of BMPs), EPA
recommends that small MS4 operators
evaluate various O&M management
agreement options. The most common
options are agreements between the

-------
            Federal Register/Vol.  64,  No. 235/Wednesday, December 8,  1999/Rules and Regulations    68761
  MS4 operator and another party such as
  post-development landowners (e.g.,
  homeowners' associations, office park
  owners, other government departments
  or entities), or regional authorities (e.g.,
  flood control districts, councils of
  government). These agreements
  typically require the post-construction
  property owner to be responsible for the
  O&M and may include conditions
  which: allow the MS4 operator to be
  reimbursed for O&M performed by the
  MS4 operator that is the responsibility
  of the property owner but is not
  performed; allow the MS4 operator to
  enter the property for inspection
  purposes; and in some cases specify that
  the property owner submit periodic
  reports.
  . In providing the guidance above,  EPA
  intends the requirements in today's rule
  to be consistent with the permit
  application requirements for large MS4s
  for post-construction controls for new
  development and redevelopment. MS4
  operators have significant flexibility
 both to develop this measure as
 appropriate to address local concerns,
 and to apply new control technologies
 as they become available. Storm water
 pollution control technologies are
 constantly being improved. EPA
 recommends that MS4s be responsive to
 these changes, developments or
 improvements in control technologies.
 EPA will provide more detailed
 guidance addressing the responsibility
 for long-term O&M of storm water
 controls in guidance materials. The
 guidance will also provide information
 on appropriate planning considerations,
 structural controls and non-structural
 controls. EPA also intends to develop a
 broad menu of BMPs as guidance to
 ensure flexibility to accommodate local
 conditions.
   EPA received comments suggesting
 that requirements for new development
 be treated separately from
 redevelopment in the rule. The
 comment stressed  that new
 development on raw land presents
 fewer obstacles and more opportunities
 to incorporate elements for preventing
 water quality impacts, whereas
 redevelopment projects are constrained
 by space limitations and existing
 infrastructure. Another comment
 suggested allowing waivers from the
 redevelopment requirements if the
 redevelopment does not result in
 additional adverse water quality
 impacts, and where BMPs are not
 technologically or economically
 feasible. EPA recognizes that
 redevelopment projects may have more
 site constraints \vhich narrow the range
of appropriate  BMPs. Today's rule
provides small MS4 operators with the
 flexibility to develop requirements that
 may be different for redevelopment
 projects, and may also include
 allowances for alternate or off-site BMPs
 at certain redevelopment projects. Non-
 structural BMPs may be the most
 appropriate approach for smaller
 redevelopment projects.
   EPA received comments requesting
 clarification on what is meant by "pre-
 development" conditions within the
 context of redevelopment. Pre-
 development refers to runoff conditions
 that exist onsite immediately before the
 planned development activities occur.
 Pre-development is not intended to be
 interpreted as that period  before any
 human-induced land disturbance
 activity has occurred.
   EPA received comments on the
 guidance language in the proposed rule
 and preamble which suggest that
 implementation of this measure should
 "attempt to maintain pre-development
 runoff conditions" and that "post-
 development conditions should not be
 different than pre-development
 conditions in a way that adversely
 affects water quality." Many comments
 expressed concern that maintaining pre-
 development runoff conditions is
 impossible and cost-prohibitive, and
 objected to any reference to "flow" or
 increase in volume of runoff. Other
 comments  support the inclusion of this
 language in the final rule. Similar
 references  in today's rule relating to pre-
 development runoff conditions are
 intended as recommendations to
 attempt to maintain pre-development
 runoff conditions. With these
 recommendations, EPA intends to
 prevent water quality impacts resulting
 from increased discharges  of pollutants,
 which may result from increased
 volume of runoff. In many  cases,
 consideration of the increased flow rate,
 velocity and energy of storm water
 discharges  following development
 unavoidably must be taken into
 consideration in order to reduce the
 discharge of pollutants, to meet water
 quality standards and to prevent
 degradation of receiving streams.  EPA
 recommends that municipalities
 consider these factors when developing
 their post-construction storm water
 management program.
  Some comments said that the quoted
 phrases in the paragraph above are
 directives that imply federal land use
 control, which they argue is beyond the
 authority of the CWA. EPA recognizes
 that land use planning is within the
 authority of local governments.
  EPA disagrees, however,  with the
 implication that today's rule dictates
 any such land use decisions. The
requirement for small MS4 operators  to
 develop a program to address discharges
 resulting from new development and
 redevelopment is essentially a pollution
 prevention measure. The Rule provides
 the MS4 operator with flexibility to
 determine the appropriate BMPs to
 address local water quality concerns.
 EPA recognizes that these program goals
 may not be applied to every site, and
 expects that MS4s will develop an
 appropriate combination of BMPs to be
 applied on a site-by-site, regional or
 watershed basis.
   vi. Pollution Prevention/Good
 Housekeeping for Municipal
 Operations. Under today's final rule,
 operators of MS4s must develop and
 implement an operation and
 maintenance program ("program") that
 includes a training component and has
 the ultimate goal  of preventing or
 reducing storm water from municipal
 operations (in addition to those that
 constitute storm water discharges
 associated with industrial activity). This
 measure's emphasis on proper O&M of
 MS4s and employee training, as
 opposed to requiring the MS4 to
 undertake major new activities, is meant
 to ensure that municipal activities are
 performed in the most efficient way to
 minimize contamination of storm water
 discharges.
  The program must include
 government employee training that
 addresses prevention measures
 pertaining to municipal  operations such
 as:  parks, golf courses and open space
 maintenance; fleet maintenance; new
 construction or land disturbance;
 building oversight; planning; and storm
 water system maintenance. The program
 can use existing storm water pollution
 prevention training materials provided
 by the State, Tribe, EPA, or
 environmental, public interest, or trade
 organizations.
  EPA also encourages operators of
 MS4s to consider the following in
 developing a program: (1) Implement
 maintenance activities, maintenance
 schedules, and long-term inspection
 procedures for structural and non-
 structural  storm water controls to
 reduce floatables and other pollutants
 discharged from the separate storm
 sewers;  (2) implement controls for
 reducing or eliminating the discharge of
 pollutants from streets, roads, highways,
 municipal parking lots, maintenance
 and storage yards, waste transfer  '
 stations, fleet or maintenance shops
 with outdoor storage areas, and salt/
 sand storage locations and snow
 disposal areas  operated by the MS4; (3)
adopt procedures for the proper
disposal of waste removed from the
separate storm sewer systems and areas
listed above in (2), including dredge

-------
68762    Federal Register/Vol. 64, No.  235/Wednesday,  December 8, 1999/Rules and Regulations.
spoil, accumulated sediments,
floatables, and other debris; and (4)
adopt procedures to ensure that new
flood management projects are assessed •
for impacts on water quality and
existing projects are assessed for
incorporation of additional water
quality protection devices or practices.
Ultimately, the effective performance of
the program measure depends on the
proper maintenance of the BMPs, both
structural and non-structural. Without
proper maintenance, BMP performance
declines significantly over time.
Additionally, BMP neglect may produce
health and safety threats,  such as
structural failure leading to flooding,
undesirable animal and insect breeding,
and odors. Maintenance of structural
BMPs could include: replacing upper
levels of gravel; dredging  of detention
ponds; and repairing of retention basin
outlet structure integrity.  Maintenance
of non-structural BMPs could include
updating educational materials
periodically.
  EPA emphasizes that programs should
identify and incorporate existing storm
water practices and training, as well as
non-storm water practices or programs
that have storm water pollution
prevention benefits, as a means to avoid
duplication of efforts and reduce overall
costs. EPA recommends that MS4s
incorporate these new obligations into
their existing programs to the greatest
extent feasible and urges States to
evaluate MS4 programs with
programmatic efficiency in mind. EPA
designed this minimum control measure
as a modified version of the permit
application requirements  for medium
and large MS4s described at 40 CFR
122.26(d)(2)(iv),  in order to provide
more flexibility for these smaller MS4s.
Today's requirements provide for a
consistent approach to control
pollutants from O&M among medium,
large, and regulated small MS4s.
  By properly implementing a program,
operators of MS4s serve as a model for
the rest of the regulated community.
Furthermore, the establishment of a
long-term program could  result in cost
savings by minimizing possible damage
to the system from floatables and other
debris and, consequently, reducing the
need for repairs.
  EPA received comments requesting
clarification of what this measure
requires. Certain municipalities
expressed concern that the measure has
the potential to impose significant costs
associated with EPA's requirement that
operators of MS4s consider
implementing controls for reducing or
eliminating the discharge of pollutants
from streets, roads, highways, municipal
parking lots, and salt/sand storage
locations and snow disposal areas
operated by the municipality. EPA
disagrees that a requirement to consider
such controls will impose considerable
costs.
  One commenter objected to the
preamble language from the proposal
suggesting that EPA does not expect the
MS4 to undertake new activity. While it
remains the Agency's expectation that
major new activity will not be required,
the MEP process should drive MS4s to
incorporate the measure's obligations
into their existing programs to achieve
the pollutant reductions to the
maximum extent practicable.
  Certain commenters requested a
definition for "municipal operations."
EPA has revised the language to more
clearly define municipal operations.
Questions may remain concerning
whether discharges from specific
municipal activities constitute
discharges associated with industrial
activities (requiring NPDES permit
authorization according to the
requirements for industrial storm water
that apply in that State) or from
municipal operations (subject only to
the controls developed in the MS4
control program). Even though there
may be different substantive
requirements that apply depending on
the source of the discharge, EPA has
modified the deadlines for permit
.coverage so that all the regulated
municipally owned and operated
sources become subject to permit
requirements on the same date. The
deadline is the same for permit coverage
for this minimum measure as for permit
coverage for municipally owned/
operated industrial sources.

c. Application Requirements
  An NFPDES permit that authorizes the
discharge from a regulated small MS4
may take the form of either an
individual permit issued to one or more
facilities as co-permittees or a general
permit that applies to a group of MS4s.
For reasons of administrative efficiency
and to reduce the paperwork burden on
permittees, EPA expects that most
discharges from regulated small MS4s
will be authorized under general
permits. These NPDES general permits
will provide specific instructions on
how to obtain coverage, including
application requirements. Typically,
such application requirements will be
satisfied by the submission of a Notice
of Intent (NOI) to be covered by the
general permit. In this section, EPA
explains the small MS4 operator's
application requirements for obtaining
coverage under a NPDES permit for
storm water.
  i. Best Management Practices and
Measurable Goals, Section 122.34(d) of
today's rule requires the operator of a
regulated small MS4 that wishes to
implement a program under § 122.34 to
identify and submit to the NPDES
permitting authority a list of the best
management practices ("BMPs") that
will be implemented for each minimum
control measure in their storm water
management program. They also must
submit measurable goals for the
development and implementation of
each BMP. The BMPs and the
measurable goals must be included
either in an NOI to be covered under a
general permit or in an individual
permit application.
  The operator's submission must
identify, as appropriate, the months and
years in which the operator will
undertake actions required to
implement each of the minimum  control
measures, including interim milestones
and the frequency of periodic actions.
The Agency revised references to
"starting and completing" actions from
the proposed rule because many actions
will be repetitive or ongoing. The
submission also must identify the
person or persons responsible for
implementing or coordinating the small
MS4 storm water program. See
§ 122.34(d). The submitted BMPs and
measurable goals become enforceable
according to the terms of the permit.
The first permit can allow the permittee
up to five years to fully implement the
storm water management program.
  Several commenters opposed making
the measurable goals enforceable  permit
conditions. Some suggested that a
permittee should be able to change its
goals so that BMPs that are not
functioning as  intended can be replaced.
EPA agrees that a permittee should be
free to switch its BMPs and
corresponding goals to others that
accomplish the minimum measure or
measures. The permittee is required to
implement BMPs that address the
minimum measures in § 122.34(b). If the
permittee determines that its original
combination of BMPs are not adequate
to achieve the objectives of the
municipal program, the MS4 should
revise its program to implement BMPs
that are adequate and submit to the
permitting authority a revised list of
BMPs and measurable goals. EPA
suggests that permits describe the
process for revising BMPs and
measurable goals, such  as whether the
permittee should follow the same
procedures as were required for the
submission of the original NOI and
whether the permitting authority's
approval is necessary prior to the
permittee  implementing the revised

-------
            Federal Register/Vol. 64, No. 235/Wednesday, December 8,  1999/Rules and Regulations    68763
 BMPs. The permittee should indicate on
 its periodic report whether any BMPs
 and measurable goals have been revised
 since the last periodic report.
   Some commenters expressed concern
 that making the measurable goals
 enforceable would encourage the
 development of easily attained goals
 and, conversely, discourage the setting
 of ambitious goals. Others noted that it
 is often difficult to determine the
 pollutant reduction that can be achieved
 by BMPs until several years after
 implementation. Much of the opposition
 to the enforceability of measurable goals
 appears to have been based on a
 mistaken understanding that measurable
 goals must consist of pollutant
 reduction targets to be achieved by the
 corresponding BMPs.
   Today's rule requires the operator to
 submit either measurable goals that
 serve as BMP design objectives or goals
 that quantify the progress of
 implementation of the actions or
 performance of the permittee's BMPs. At
 a minimum, the required measurable
 goals should describe specific actions
 taken by the permittee to implement
 each BMP and the frequency and the
 dates for such actions. Although the
 operator may choose to do so, it is not
 required to submit goals that measure
 whether a BMP or combination of BMPs
 is effective in achieving a specific result
 in terms  of storm water discharge
 quality. For example, a measurable goal
 might involve a commitment to inspect
 a given number of drainage areas of the
 collection system for illicit connections
 by a certain date. The measurable goal
 need not commit to achieving a specific
 amount of pollutant reduction through
 the elimination of illicit connections.
 Other measurable goals could include
 the date by which public education
 materials would be developed, a certain
 percentage of the community
 participating in a clean-up campaign,
 the development of a mechanism to
 address construction site runoff, and a
 reduction in the percentage of
 imperviousness associated with new
 development projects.
  To reduce the risk that permittees will
 develop inadequate BMPs, EPA intends
 to develop a menu of BMPs to assist the
 operators of regulated small MS4s with
 the development of municipal
 programs. States may also develop a
 menu of BMPs. Today's rule provides
 that the measurable goals that
 demonstrate compliance with the
 minimum control measures  in §§ 122.34
 (b)(3) through (b)(6) do not have to be
 met if the State or EPA has not issued
 a menu of BMPs at the time the MS4
submits its NOI. Commenters pointed
out that the proposed rule would have
 made the measurable goals
 unenforceable if the menu of BMPs was
 not available, but the proposal was
 silent as to the enforceability of the
 implementation of BMPs. Today's rule
 clarifies that the operators are not free
 to do nothing prior to the issuance of a
 menu of BMPs; they still must make a
 good faith effort to implement the BMPs
 designed to comply with each measure.
 See § 122.34(d)(2). The operators would
 not, however, be liable for failure to
 meet its measurable goals if a menu of
 BMPs was not available at the time they
 submit their NOI.
   The proposed rule provision in
 § 123.35 stated that the "[fjailure to
 issue the menu of BMPs would not
 affect the legal status of the general
 permit." This concept is included in the
 final rule in § 122.34(d)(2)'s clarification
 that the permittee still must comply
 with other requirements of the general
 permit.
   Unlike the proposed rule, today's rule
 does not require that each BMP in the
 menu developed by the State or EPA be
 regionally appropriate, cost-effective
 and field-tested. Various commenters
 criticized those criteria as unworkable,
 and one described them as "ripe for
 ambiguity and abuse." Other
 commenters feared that the operators of
 regulated small MS4s would never be
 required to achieve their goals until
 menus were developed that were cost-
 effective, field-tested and appropriate
 for every conceivable subregion.
   While some municipal commenters
 supported the requirement that a menu
 of BMPs be made available that
 included BMPs that had been
 determined to be regionally appropriate,
 field-tested and cost-effective, others
 raised concerns that they would be
 restricted to a limited menu. Some
 commenters supported such a detailed
 menu because they thought they would
 only be able to select BMPs that were on
 the menu, while others thought that it
 was the permitting  authority's
 responsibility to develop BMPs
 narrowly tailored to their situation. In
 response, EPA notes that the operators
 will not be restricted to implementing
 only, or all of, the BMPs included on the
 menu. Since the menu does not require
 permittees to implement the BMPs
 included on the menu, it is also not
 necessary to apply the public notice and
 other procedures that some commenters
 thought should be applied to the
 development of the menu of BMPs.
  The purpose of the BMP menu is to
 provide guidance to assist the operators
 of regulated small MS4s with the
 development and refinement of their
local program, not to limit their options.
Permittees may implement BMPs other
 than those on the menu unless a State
 restricts its permittees to specific BMPs.
 To the extent possible, EPA will
 develop a menu of BMPs that describes
 the appropriateness of BMPs to specific
 regions, whether the BMPs have been
 field-tested, and their approximate
 costs. The menu, however, is not
 intended to relieve permittees of the
 need to implement BMPs that are
 appropriate for their specific
 circumstances.
   If there are no known relevant BMPs
 for a specific circumstance, a permittee
 has the option of developing and
 implementing pilot BMPs that may be
 better suited to their circumstances.
 Where BMPs are experimental, the
 permittee should consider committing
 to measurable goals that address its
 schedule for implementing its selected
 BMPs rather than goals of achieving
 specific pollutant reductions. If the
 BMPs implemented by the permittee do
 not achieve the desired objective, the
 permittee may be required to commit to
 different or revised BMPs.
   As stated in § 123.35(g), EPA is
 committed to issuing a menu of BMPs
 prior to the deadline for the issuance of
 permits. This menu would serve as
 guidance for all operators of regulated
 small MS4s nationwide. After
 developing the initial menu of BMPs,
 EPA intends to periodically modify,
 update, and supplement the menu of
 BMPs based on the assessments of the
 MS4 storm water program and research.
 States may rely on EPA's menu of BMPs
 or issue their own.  If States develop
 their own menus, they would constitute
 additional guidance (or perhaps
 requirements in some States) for the
 operators to follow. Several commenters
 were confused by the proposed rule
 language that stated that States must
 provide or issue a menu of BMPs and,
 if they fail to do so, EPA "may" do so.
 Some read this language as not requiring
 either EPA or the State to develop the
 menu. EPA had intended that it would
 develop a menu and that States could
 either provide the EPA developed menu
 or one developed by the State.
   EPA has dropped the proposed
 language that States "must" develop the
 menu of BMPs. Some commenters
 thought that it was  inappropriate to
 require States to issue guidance. A
 menu of BMPs issued by either EPA or
 a permittee's State will satisfy the
 condition in § 122.34(dJ that a
regulatory authority provide a menu of
BMPs. A State could require its
permittees to follow its menu of BMPs
provided that they are adequate to
implement § 122.34(b).
  Several commenters raised concerns
that operators of small MS4s could be

-------
68764   Federal Register/Vol. 64, No.  235/Wednesday,  December 8, 1999/Rules and Regulations
required to submit their BMPs and
measurable goals before EPA or the
State has issued a menu of BMPs. EPA
has assumed primary responsibility for .
developing a menu of BMPs to
minimize the possibility of this
occurring. Should a general permit be
issued before a menu of BMPs is
available, the permit writer would have
the option of delaying the date by which
the identification of the BMPs and
measurable goals must be submitted to
the permitting authority until some time
after a menu of BMPs is available.
  Several municipal commenters raised
concerns that they would begin to
develop a program only to be later told
by the permitting authority or
challenged in a citizen  suit that their
BMPs were inadequate. They expressed
a need for certainty regarding what their
permit required. Several commenters
suggested that EPA require permitting
authorities to approve or disapprove the
submitted BMPs and measurable goals.
EPA disagrees that formal approval or
disapproval by the permitting authority
is needed.
  EPA acknowledges that the lack of a
formal approval process does place on
the permittee some responsibility for
designing and determining the adequacy
of its BMPs. Once the permittee has
submitted its BMPs to the permitting
authority as part of its NOI, it must
implement them in order to achieve the
corresponding measurable goals. EPA
does not believe that this results in the
uncertainty to the extent expressed by
some commenters or unduly expose the
permittee to the risk of citizen suit. If
the permit is very specific regarding
what the permittee must do,  then the
uncertainty is eliminated. If the permit
is less prescriptive, the permittee has
greater latitude in determining for itself
what constitutes an adequate program.
A citizen suit could impose liability on
the permittee only if the program that it
develops and implements clearly does
not satisfy  the requirements of the
general permit. EPA believes today's
approach strikes a balance between the
competing goals of providing certainty
as to what  constitutes an adequate
program and providing flexibility to the
permittees.
  Commenters were divided on whether
five years was a reasonable and
expeditious schedule for a MS4 to
implement its program. Some thought
that it was an appropriate amount of
time to  allow for the development and
implementation of adequate  programs.
One questioned whether the permittee
had to be implementing all of its
program within that time, and suggested
that there may be cases where a
permitting authority would need
flexibility to allow more time. One
commenter suggested that five years is
too long and would amount to a
relaxation of implementation in their
area. EPA believes it will take
considerable time to complete the tasks
of initially developing a program,
commencing to implement it, and
achieving results. EPA notes, however,
that full implementation of an
appropriate program must occur as
expeditiously as possible, and not later
than five years.
  EPA solicited comment on how an
NOI form might best be formatted to
allow for measurable goal information
(e.g., through the use of check boxes or
narrative descriptions) while taking into
account the Agency's intention to
facilitate computer tracking. All
commenters supported the development
of a checklist NOI, but most noted that
there would need to be room for
additional information to cover unusual
situations. One noted that, while a
summary of measurable goals might be
reduced to  one sheet, attachments that
more fully described the program and
the planned BMPs would be necessary.
EPA agrees that in most cases a
"checklist" will not be able to capture
the information on what BMPs a
permittee intends to implement and its
measurable goals for their
implementation. EPA will continue to
consider whether to develop a model
NOI  form and make it available for
permitting  authorities that choose to use
it. What will be required on an MS4's
NOI, however, is more extensive than
what is usually required on an NOI, so
a "form" NOI for MS4s  may be
impractical.
  ii.  Individual Permit Application for a
§ 122.34(b) program. In some cases, an
operator of a regulated small MS4s may
seek coverage under an individual
NPDES permit, either because it chooses
to do so or  because the NPDES
permitting  authority has not made the
general permit option available to that
source. For small MS4s that are to
implement a § 122.34(b) program in
today's rule, EPA is promulgating
simplified individual permit application
requirements at § 122.33(b)(2)(i). Under
the simplified individual permit
application requirements, the operator
submits an application  to the NPDES
permitting  authority that includes the
information required under § 122.21(f)
and an estimate of square mileage
served by the small MS4. They are also
required to supply the BMP and
measurable goal information required
under § 122.34(d). Consistent with CWA
section 308 and analogous State law, the
permitting  authority could request any
additional  information  to gain a better
understanding of the system and the
areas draining into the system.
  Commenters suggested that the
requirements of § 122.21(f) are not
necessarily applicable to a small MS4.'
One suggested that it was not
appropriate to require the following
information: a description of the
activities conducted by the applicant
which require it to obtain an NPDES
permit; the name, mailing address, and
location of the facility; and up to four
Standard Industrial Classification
("SIC") codes which best reflect the
principal products or services provided
by the facility. In response, EPA notes
that the requirements in § 122.21 (f) are
generic application requirements
applicable to NPDES applicants. With
the exception of the SIC code
requirement, EPA believes that they are
applicable to MS4s.  In the SIC code
portion of the standard application, the
applicant may simply put "not
applicable."
  One commenter asked that EPA
clarify whether § 122.21(f)(5)'s
requirement to indicate "whether the
facility is located on Indian lands,"
referred to tribal lands, Indian country,
or Indian reservations. For some local
governments this is a complex issue
with no easy "yes" or "no" answer. See
the discussion in the Section II.F in the
proposal to today's rule regarding what
tribal lands are subject to the federal
trust responsibility for purposes of the
NPDES program.
  One commenter suggested that the
application should not have to  list the
permits and approvals required under
§ 122.21[f)(6). EPA notes that the
applicant must only list the
environmental permits that the
applicant has received that cover the
small MS4. The applicant is not
required to list permits for other
operations conducted by the small MS4
operator (e.g., for an operation of an
airport or landfill). Again, in most cases
the applicant could respond "not
applicable" to this portion of the
application.
  One commenter suggested that the
topographic map requirement of
§ 122.21 (f)(7) was completely different
from, and significantly more onerous
than, the mapping requirement outlined
in the proposed rule at § 122.34(b)(3)(i).
EPA agrees and has  modified the final
rule to clarify that a map that satisfies
the requirements of § 122.34(b)(3)(i) also
satisfies the map requirements  for MS4
applicants seeking individual permits
under § 122.33(b)(2)(i).
  EPA is adding a new paragraph to
§ 122.44(k) to clarify that requirements
to implement BMPs developed pursuant
to CWA 402(p) are appropriate permit

-------
                    Federal Register/Vol.  64, No. 235/Wednesday, December 8,  1999/Rules and Regulations    68765
          conditions. While such conditions
          could be included under the existing
          provision in § 122.44(k)(3) for "practices
          reasonably necessary to achieve effluent
          limitations and standards or to carry out
          the purposes and intent of the CWA,"
          EPA believes it is clearer to specifically
          list in § 122.44(k) BMPs that implement
          storm water programs in light of the
          frequency with which they are used as
          effluent limitations.
            ///. Alternative Permit Options/Tenth
          Amendment. As an alternative to
          implementing a program that addresses
          each of the six minimum measures
          according to the requirements of
          § 122.34(b), today's rule provides the
          operators of regulated small MS4s with
          the option of applying for an individual
          permit under existing § 122.26(d). See
          § 122.33(b)(2)(ii). If a system operator
          does not want to be held accountable for
          implementation of each of the minimum
          measures, an individual permit option
          under § 122.33(b)(2)(ii) remains
          available. (As explained in the next
          section of this preamble, § 122.35(b) also
          provides an opportunity for relief from
          permit obligations for some of the
          minimum measures, but that relief
          exists within the framework of the
          minimum measures.)
           EPA originally drafted the individual
          permit application requirements in
          § 122.26(d) to apply to medium and
          large MS4s. Today's rule abbreviates the
          individual permit application
          requirements for small MS4s. Although
          EPA believes that the storm water
          management program requirements of
          § 122.34, including the minimum
          measures, provide the most appropriate
          means to control pollutants from most
          small MS4s, the Agency does recognize
          that the operators of some small MS4s
          may prefer more individualized permit
          requirements. Among other possible
         reasons, an operator may seek to avoid
         having to "regulate" third parties
          discharging into the separate storm
         sewer system. Alternatively, an operator
         may determine that structural controls,
         such as constructed wetlands, are more
         appropriate or effective to address the
         discharges that would otherwise be
         addressed under the construction and/
         or development/redevelopment
         measures.
           Some MS4s commenters alleged that
         an absolute requirement to implement
         the minimum measures violates the
         Tenth Amendment to the U.S.
         Constitution. While EPA disagrees that
         requiring MS4s to implement the
         minimum measures would violate the
         Constitution, today's rule does provide
         small MS4s with the option of
         developing more individualized
         measures to reduce the pollutants and
 pollution associated with urban storm
 water that will be regulated under
 today's rule.
   Some commenters specifically
 objected that § 122.34's minimum
 measures for small MS4s violate the
 Tenth Amendment insofar as they
 require the operators of MS4s to regulate
 third parties. The minimum measures
 include requirements for small MS4
 operators to prohibit certain non-storm
 water discharges, control storm water
 discharges from construction greater
 than one acre, and take other actions to
 control third party sources of storm
 water discharges into their MS4s.
 Commenters also argued that it was
 inappropriate for EPA to require local
 governments to enact ordinances that
 will consume local revenues and put
 local governments in the position of
 bearing the political responsibility for
 implementing the program. One
 commenter argued that EPA was
 prohibited from conditioning the
 issuance of an NPDES permit upon the
 small MS4 operators waiving their
 constitutional right to be free from such
 requirements to regulate third parties.
 The Agency replies to each comment in
 turn.
   Because the rule does rely on local
 governments—who operate municipal
 separate storm sewer systems—to
 regulate discharges from third parties
 into storm sewers, EPA acknowledges
 that the rule implicates the Tenth
 Amendment and constitutional
 principles of federalism. EPA disagrees,
 however, that today's rule is
 inconsistent with federalism principles.
 I As political subdivisions of States,
 municipalities enjoy the same
 protections as States under the Tenth
 Amendment.]
  The  Supreme Court has interpreted
 the Tenth Amendment to preclude
 federal actions that compel States or
 their political subdivisions to enact or
 administer a federal regulatory program.
 See New Yorkv. United States, 505 U.S.
 144 (1992); Printzv. United States, 117
 S.Ct. 2365 (1997). The Printecase,
 however, did acknowledge that the
 restriction does not apply when federal
 requirements of general applicability—
 requirements that regulate all parties
 engaging in a particular activity—do not
 excessively interfere with the
 functioning of State governments when
 those requirements are applied to States
 (or their political subdivisions). See
 Printz, 117 S.Ct. at 2383.
  Today's rule imposes a federal
 requirement of general applicability,
namely, the requirement to obtain and
 comply with an NPDES permit, on
municipalities that operate a municipal
separate storm sewer system. By virtue
 of this rule, the permit will require the
 municipality/storm sewer operator to
 develop a storm water control program.
 The rule specifies the components of the
 control program, which are primarily
 "management'-type controls, for
 example, municipal regulation of third
 party storm water discharges associated
 with construction, as well as
 development and redevelopment, when
 those discharges would enter the
 municipal system.

   Unlike the circumstances reviewed in
 the New York and Printz cases, today's
 rule merely applies a generally
 applicable requirement (the CWA
 permit requirement) to municipal point
 sources. The CWA establishes a
 generally applicable requirement to
, obtain an NPDES permit to authorize
 point source discharge to waters of the
 United States. Because municipalities
 own and operate separate storm sewers,
 including storm sewers into which third
 parties may discharge pollutants,
 NPDES permits may require
 municipalities to control the discharge
 of pollutants into the storm sewers in
 the first instance. Because NPDES
 permits can impose end-of-pipe
 numeric effluent limits, narrative
 effluent limits in the form of
 "management" program requirements
 are also within the scope of Clean Water
 Act authority. As noted above, however,
 EPA believes that such narrative
 limitations are the most appropriate
 form of effluent limitation for these
 types of permits. For municipal separate
 storm sewer permits, CWA section
 402(p)(3)(B)(iii) specifically authorizes
 "controls to reduce pollutants to the
 maximum extent practicable, including
 management practices, control
 techniques and system, design and
 engineering methods, and such other
 provisions as the Administrator or the
 State determines appropriate for the
 control of such pollutants."
   The Agency did not design the
 minimum measures in § 122.34 to
 "commandeer" state regulatory
 mechanisms, but rather to reduce
 pollutant discharges from small MS4s.
 The permit requirement in CWA section
 402 is a requirement of general
 applicability. The operator of a small
 MS4 that does not prohibit and/or
 control discharges into its system
 essentially accepts "title" for those
 discharges. At a minimum, by providing
 free and open access to the MS4s that
 convey discharges to the waters of the
 United States, the municipal storm
 sewer system enables water quality
 impairment by third parties. Section
 122.34 requires the operator of a
 regulated small MS4 to control a third
_

-------
68766    Federal Register/Vol. 64, No.  235/Wednesday, December 8,  1999/Rules and Regulations
party only to the extent that the MS4
collection system receives pollutants
from that third party and discharges it
to the waters of the United States. The •
operators of regulated small MS4s
cannot passively receive and discharge
pollutants from third parties. The
Agency concedes that administration  of
a municipal program will consume
limited local revenues for
implementation; but those
consequences stem from the municipal
operator's identity as a permitted sewer
system operator. The Tenth Amendment
does not create a blanket municipal
immunity from generally applicable
requirements. Development of a
program based on the minimum
measures and implementation of that
program should not "excessively
interfere" with the functioning of
municipal government, especially given
the "practicability" threshold under
CWA section 402(p)(3)(B)(iii).
  As noted above, today's rule also
allows regulated small MS4s to opt out
of the minimum measures approach.
The individual permit option provides
for greater flexibility in program
implementation and also responds to
the comment about requiring a
municipal permit applicant's waiver of
any arguable constitutional rights. The
individual permit option responds to
questions about the rule's alleged
unconstitutionally by more specifically
focusing on the pollutants discharged
from municipal point sources. Today's
rule gives operators  of MS4s the option
to seek an individual permit that varies
from the minimum measures/
management approach that is otherwise
specified in today's rule. Even if the
minimum measures approach was
constitutionally suspect, a requirement
that standing alone would violate
constitutional principles of federalism
does not raise concerns if the entity
subject to the requirement may opt for
an alternative action that does not raise
a federalism issue.
  For municipal system operators who
seek to avoid third party regulation
according to all or some of the
minimum measures, § 122.26(d)
requires the operator to submit a
narrative description of its storm water
sewer system and any existing storm
water control program, as well as the
monitoring data to enable the permit
writer to develop appropriate permit
conditions. The permit writer can then
develop permit conditions and
limitations that vary from the six
minimum measures prescribed in
today's rule. The information will
enable the permit writer to develop an
NPDES permit that will result in
pollutant reduction to the maximum
extent practicable. See NRDCv. EPA,
966 F.2d at 1308, n!7. If determined
appropriate under CWA section
402(p)(3)(B)(iii), for example BMPs to
meet water quality standards, the permit
could also incorporate any more
stringent or prescriptive effluent limits
based on the individual permit
application information.
  For small MS4 operators seeking an
individual permit, both Part 1 and Part
2 of the application requirements in
§ 122.26(d)(l) and (2) are required to be
submitted within 3 years and 90 days of
the date of publication of this Federal
Register notice. Some of the information
required in Part 1 will necessarily have
to be developed by the permit applicant
prior to the development of Part 2 of the
application. The permit applicant
should coordinate with its permitting
authority regarding the timing of review
of the information.
  The operators of regulated small MS4s
that apply under § 122.26(d) may apply
to implement certain of the § 122.34(b)
minimum control measures, and thereby
focus the necessary evaluation for
additional limitations on alternative
controls to the § 122.34(b) measures that
the small MS4 will not implement. The
permit writer may determine
"equivalency" for some or all of the
minimum measures by developing a
rough estimate of the pollutant
reduction that would be achieved if the
MS4 implemented the § 122.34
minimum measure and to incorporate
that pollutant reduction estimate in the
small MS4's individual permit as an
effluent limitation. The Agency
recognizes that, based on current
information, any such estimates will
probably have a wide range.
Anticipation of this wide range is one of
the reasons EPA believes MS4 operators
need flexibility in determining the mix
of BMPs (under the minimum measures]
to achieve water quality objectives.
Therefore, for example, if a system
operator seeks to employ an alternative
that involves structural controls, wide
ranges will  probably be associated with
gross pollutant reduction estimates.
Permit writers will undoubtedly
develop other ways to ensure that
permit limits ensure reduction of
pollutants to the maximum extent
practicable.
  Small MS4 operators that pursue this
individual permit option do not need to
submit details about their future
program requirements (e.g., the MS4's
future plans to obtain legal authority
required by §§ 122.26(d)(l)(ii) and
(d)(2)). A small MS4 operator might
elect to supply such information if it
intends for the permit writer to take
those plans into account when
developing the small MS4's permit
conditions.
  Several operators of small MS4s
commented that they currently lacked
the authority they would need to
implement one or more of the minimum
measures in § 122.34(b). Today's rule
recognizes that the operators of some
small MS4s might not have the
authority under State law to implement
one or more of the measures using, for
example, an ordinance or other
regulatory mechanism. To address these
situations, each minimum measure in
§ 122.34(b) that would require the small
MS4 operator to develop an ordinance
or other regulatory mechanism states
that the operator is only required to
implement that requirement to "the
extent allowable under State, Tribal or
local law." See § 122.34(b)(3)(ii) (illicit
discharge elimination), §122.34(b)(4)(ii)
(construction runoff control) and
§ 122.34(b)(5)(ii) (post-construction
storm water management). This
regulatory language does not mean that
a operator of a small MS4 with
ordinance making authority can simply
fail to pass an ordinance necessary for
a § 122.34(b) program. The reference to
"the extent allowable under * *  * local
law" refers to the local laws of other
political subdivisions to which the MS4
operator is subject. Rather, a small MS4
operator that seeks to implement a
program under section § 122.34(b) may
omit a requirement to develop an
ordinance or other regulatory
mechanism only to the extent its
municipal charter, State constitution or
other legal authority prevents the
operator from exercising the necessary
authority. Where the operator cannot
obtain the authority to implement any
activity that is only required to "the
extent allowable under State, Tribal or
local law," the operator may satisfy
today's rule by administering the
remaining § 122.34(b) requirements.
  Finally, although today's rule
provides operators of small MS4s with
an option of applying for a permit under
§ 122.26(d), States authorized to
administer the NPDES program are not
required to provide this option. NPDES-
authorized States could require all
regulated small MS4s to be permitted
under the minimum measures
management approach in § 122.34 as a
matter of State law. Such an approach
would be deemed to be equally or more
stringent than what is required by
today's rule. See 40 CFR 123.2(i). The
federalism concerns discussed above do
not apply to requirements imposed by a
State on its political subdivisions.
  iv. Satisfaction of Minimum Measure
Obligations by Another Entity. An
operator of a regulated small MS4 may

-------
           Federal Register/Vol.  64,  No. 235/Wednesday, December 8,  1999/Rules and .Regulations    68767
 satisfy the requirement to implement
 one or more of the six minimum
 measures in § 122.3'4(b) by having a
 third party implement the measure or
 measures. Today's rule provides a
 variety of means for small MS4
 operators to share responsibility for
 different aspects of their storm water
 management program. The means by
 which the operators of various MS4s
 share responsibility may affect who is
 ultimately responsible for performance
 of the minimum measure and who files
 the periodic reports on the
 implementation of the minimum
 measure. Section 122.35 addresses these
 issues. The rule describes two different
 variants on third party implementation
 with different consequences if the third
 party fails to implement the measure.
   If the permit covering the discharge
 from a regulated small MS4 identifies
 the operator as the entity responsible for
 a particular minimum control measure,
 then the operator-permittee remains
 responsible for the implementation of
 that measure even if another entity has
 agreed to implement the control
 measure. Section 122.35 (a). Another
 party may satisfy the operator-
 permittee's responsibility by
 implementing the minimum control
 measure in a manner at least as stringent
 or prescriptive as the corresponding
 NPDES permit requirement. If the third
 party fails to  do so, the operator-
 permittee remains responsible for its
 performance. The operator of the MS4
 should consider entering into an
 agreement with the third party that
 acknowledges the responsibility to
 implement the minimum measure. The
 operator-permittee's NOI and its annual
 § 122.34(f)(3) reports submitted to the
 NPDES permitting authority must
 identify the third party that is satisfying
 one or more of the permit obligations.
 This requirement ensures that the
 permitting authority is aware which
 entity is supposed to implement which
 minimum measures.
   If, on the other hand, the regulated
 small MS4's permit recognizes that an
 NPDES permittee other than the
 operator-permittee is responsible for a
 particular minimum control measure,
 then the operator-permittee is relieved
 from the responsibility for
 implementing that measure. The
 operator-permittee is also relieved from.
 the responsibility for implementing any
 measure that  the operator's permit
 indicates will be performed by the
NPDES permitting authority. Section
 122.35(b). The MS4 operator-permittee
would be responsible for implementing
 the remaining minimum measures.
  Today's final rule differs from the
proposed version of § 122.35(b), which
 stated that, even if the third party's
 responsibility is recognized in the
 permit, the MS4 operator-permittee
 remained responsible for performance if
 the third party failed to perform the
 measure consistent with § 122.34(b).
 Under today's rule, the operator-
 permittee is relieved from responsibility
 for performance of a measure if the third
 party is an NPDES permittee whose
 permit makes it responsible for
 performance of the measure (including,
 for example, a State agency other than
 the State agency that issues NPDES
 permits) or if the third party is the
 NPDES permitting authority itself.
 Because the permitting authority is
 acknowledging the third party's
 responsibility in the permit,
 commenters thought  that the MS4
 operator-permittee should not be
 responsible for ensuring that the other
 entity is implementing the control
 measure properly. EPA agrees that the
 operator-permittee should not be
 conditionally responsible when the
 requirements are enforceable against
 some other NPDES permittee. If the
 third party fails to perform the
 minimum measure, the requirements
 will be enforceable against the third
 party. In addition, the NPDES
 permitting authority could reopen the
 operator-permittee's permit under
 § 122.62 and modify the permit to make
 the operator responsible for
 implementing the measure. A new
 paragraph has been added to § 122.62 to
 clarify that the permit may be reopened
 in such  circumstances.
  Today's rule also provides that the
 operator-permittee is  not conditionally
 responsible where it is the State NPDES
 permitting authority itself that fails to
 implement the measure. The permitting
 authority does not need to issue a
 permit to itself (i.e., to the same State,
 agency that issues the permit) for the
 sole  purpose of relieving the small MS4
 from responsibility in the event the
 State agency does not satisfy its
 obligation to implement a measure. EPA
 does not believe that the small MS4
 should be responsible in the situation
where the NPDES permit issued to the
 small MS4 operator recognizes that the
 State agency that issues the permit is
responsible for implementing a
measure. If the State does fail to
 implement the measure, the State
agency could be held accountable for its
commitment in the permit to implement
the measure. Where the State does not
fulfill its responsibility to implement a
measure, a citizen also could petition
for withdrawal of the State's NPDES
program or it could petition to have the
MS4's permit reopened to require the
 MS4 operator to implement the
 measure.
   EPA notes that not every State
 program that addresses erosion and
 sediment control from construction sites
 will be adequate to satisfy the
 requirement that each regulated small
 MS4 have a program to the extent
 required by § 122.34(b)(4). For example,
 although all NPDES States are required
 to issue NPDES permits for construction
 activity that disturbs greater than one
 acre, the State's NPDES permit program
 will not necessarily be extensive enough
 to satisfy a regulated small MS4's
 obligation under § 122.34(b)(4). NPDES
 States will not necessarily be
 implementing all of the required
 elements of that minimum measure,
 such as procedures for site plan review
 in each jurisdiction required to develop
 a program and procedures for receipt
 and consideration of information
 submitted by the public on individual
 construction sites. In order for a State  .
 erosion and sediment control program
 to satisfy a small MS4 operator's
 obligation to implement § 122.34(b)(4),
 the State program would have to
 include all of the elements of that
 minimum measure.
  Where the operator-permittee is itself
 performing one or more of the minimum
 measures, the operator-permittee
 remains responsible for all of the
 reporting requirements under
 § 122.34(f)(3). The operator-permittee's
 reports should identify each entity that
 is performing the control measures
 within the geographic jurisdiction of the
 regulated small MS4. If the other entity
 also operates a regulated MS4 and files
 reports on the progress of
 implementation of the measures within
 the geographic jurisdiction of the MS4,
 then the operator-permittee need not
 include that same information in its
 own reports.
  If the other entity operates a regulated
 MS4 and is performing all of the
 minimum measures for the permittee,
 the permittee is not required to file the
 reports required by § 122.34(9(3). This
 relief from reporting is specified in
 §122.35(a).
  Section 122.35 addresses the  concerns
 of some commenters who sought relief
 for governmental facilities that are
 classified as small MS4s under  today's
 rule. These facilities frequently
 discharge storm water through another
regulated MS4 and could be regulated
by that MS4's program.  For example, a
 State owned office complex that
 operates its storm sewer system in an
 urbanized area will be regulated as an
MS4 under today's rule even though its
system may be subject to the storm
water controls of the municipality in

-------
 68768    Federal Register/Vol.  64,  No. 235/Wednesday, December 8, 1999/Rules and  Regulations
 which it is located. Today's rule
 specifically revised the definition of
 MS4 to recognize that different levels of
 government often operate MS4s and that
 each such separate entity (including the
 federal government) should be
 responsible for its discharges. If both
 MS4s agree, the downstream MS4 can
 develop a storm water management
 program that regulates the discharge
 from both MS4s. The upstream small
 MS4 operator still must submit an NOI
 that identifies the entity on which the
 upstream small MS4 operator is relying
 to satisfy its permit obligations. No
 reports are required from the upstream
 small MS4 operator, but the upstream
 operator must remain in compliance
 with the downstream MS4 operator's
 storm water management program. This
 option allows small MS4s to work
 together to develop one storm water
 management program that satisfies the
 permit obligations of both. If they
 cannot agree, the upstream small MS4
 operator must develop its own program.
  As mentioned previously, comments
 from federal facilities and State
 organizations that operate MS4s
 requested that their permit requirements
 differ from those of MS4s that are
 political subdivisions of States (cities,
 towns, counties, etc.). EPA
 acknowledges that there are differences;
 e.g., many federal and State facilities do
 not serve a resident population and thus
 might require a different approach to
 public education. EPA believes,
 however, that MS4s owned by State and
 federal governments can develop storm
 water management plans that address
 the minimum measures. Federal and
 State owned small MS4s may choose to
 work with adjacent municipally owned
 MS4s to develop a unified plan that
 addresses all of the required measures
 within the jurisdiction of all of the
 contiguous MS4s. The options in
 § 122.35 minimize the burden on small
 MS4s that are covered by another MS4's
 program.
  One commenter recommended that if
 one MS4 discharges into a second MS4,
 the operator of the upstream MS4
 should have to provide  a copy of its NOI
 or permit application to the operator of
 the receiving MS4. EPA did not adopt
 this recommendation because the NOI
 and permit application will be publicly
 available; but EPA does recommend that
 NPDES permitting authorities consider
 it as a possible permit requirement. The
 commenter also suggested that
 monitoring data should be collected by
 the upstream MS4 and provided to the
 downstream MS4. EPA  is not adopting
such a uniform monitoring requirement
because EPA believes it is more
appropriate to let the MS4 operators
 work out the need for such data. If
 necessary, the downstream MS4s might
 want to make such data a condition to
 allowing the upstream MS4 to connect
 to its system.
  v. Joint Permit Programs. Many
 commenters supported allowing the
 operators of small MS4s to apply as co-
 permittees so they each would not have
 to develop their own storm water
 management program. Today's rule
 specifically  allows regulated small
 MS4s to join with either other small
 MS4s regulated under § 122.34(d)  or
 with medium and large MS4s regulated
 under §122.26(d).
  As is discussed in the previous
 section, regulated small MS4s may
 indicate in their NOIs that another
 entity is performing one or mOre of its
 required minimum control measures.
 Today's rule under § 122.33(b)(l) also
 specifically  allows the operators of
 regulated small MS4s to jointly submit
 an NOI. The joint NOI must clearly
 indicate which entity is required to
 implement which control measure in
 each geographic jurisdiction within the
 service area  of the entire small MS4.
 The operator of each regulated small
 MS4 remains responsible  for the
 implementation of each minimum
 measure for  its MS4 (unless, as is
 discussed in the previous section above,
 the permit recognizes that another entity
 is responsible for completing the
 measure.) The joint NOI, therefore, is
 legally equivalent to each entity
 submitting its own NOI. EPA is,
 however, revising the rule language to
 specifically authorize the joint
 submission of NOIs in response to
 comments that suggested that such
 explicit authorization might encourage
 programs to  be coordinated on a
 watershed basis.
  Section 122.33(b)(2)(iii) authorizes
 regulated small MS4s to jointly apply
 for an individual permit to implement
 today's rule, where allowed by an
 NPDES permitting authority. The permit
 application should contain sufficient
 information  to allow the permitting
 authority to  allocate responsibility
 among the parties under one of the two
 permitting options in §§ 122.33(b)(2)(i)
 and (ii).
  Section 122.33(b)(3) of today's rule
 also allows an operator of a regulated
 small MS4 to join as a co-permittee in
 an existing NPDES permit issued to an
 adjoining medium or large MS4 or
source designated under the existing
 storm water  program. This co-permittee
 option applies only with the agreement
 of all co-permittees. Under this co-
permittee arrangement, the operator of
the regulated small MS4 must comply
with the terms and conditions of the
 applicable permit rather than the permit
 condition requirements of § 122.34 of
 today's rule. The regulated small MS4
 that wishes to be a co-permittee must
 comply with the applicable
 requirements of § 122.26(d), but would
 not be required to fulfill all the permit
 application requirements applicable to
 medium and large MS4s. Specifically,
 the regulated small MS4 is not required
 to comply with the application
 requirements of § 122.26(d)(l)(iii)
 (Part 1 source identification), § 122.26
 (d)(l)(iv) (Part 1 discharge
 characterization), and § 122.26(d)(2)(iii)
 (Part 2 discharge characterization data).
 Furthermore, the regulated small MS4
 operator could satisfy the requirements
 in § 122.26(d)(l)(v) (Part 1 management
 programs) and § 122.26(d)(2)(iv) (Part 2
 proposed management program) by
 referring to the adjoining MS4 operator's
 existing plan. An operator pursuing this
 option must describe in the permit
 modification request how the adjoining
 MS4's storm water program addresses or
 needs to be supplemented in order to
 adequately address discharges from the
 MS4. The request must also explain the
 role of the small MS4 operator in
 coordinating local storm water activities
 and describe the resources available to
 accomplish the storm water
 management plan.
  EPA sought comments regarding the
 appropriateness of the application
 requirements in these subsections of
 § 122.26(d). One commenter. stated that
 newly regulated smaller MS4s should
 not be required to meet the existing
 regulations' Part II application
 requirements under § 122.26(d)
 regarding the control of storm water
 discharges from industrial activity. EPA
 disagrees. The smaller MS4 operators
 designated for regulation in today's rule
 may satisfy this requirement by
 referencing the legal authority of the
 already regulated MS4 program to the
 extent the newly regulated MS4 will
 rely on such legal authority to satisfy its
 permit requirements. If the smaller MS4
 operator plans to rely on its own legal
 authorities, it must identify it in the
 application. If the smaller MS4 operator
 does not elect to use its own legal
 authority, they may file an individual
 permit application for an alternate
program under § 122.33(b)(2)(ii).
  The explanatory language in
 § 122.33(b)(3) recommends that the
 smaller MS4s designated under today's
rule identify how an existing plan
 "would need to be supplemented in
 order to adequately address your
discharges." One commenter suggested
that this must be regulatory language
and not guidance. EPA disagrees that
this needs to be mandatory language.

-------
           Federal Register/Vol.  64, No. 235/Wednesday, December  8, 1999/Rules and  Regulations    68769
 Since many of the smaller MS4s
 designated today are "donut holes"
 within the geographic jurisdiction of an
 already regulated MS4, the larger MS4's
 program generally will be adequate to
 address the newly regulated MS4's
 discharges. The small MS4 applicant
 should consider the adequacy of the
 existing MS4's program to address the
 smaller MS4's water quality needs, but
 EPA is not imposing specific
 requirements. Where circumstances
 suggest that the existing program is
 inadequate with respect to the newly
 designated MS4 and the applicant does
 not address the issue, the NPDES
 permitting authority must require that
 the existing program be supplemented.
  Commenters recommended that the
 application deadline for smaller MS4s
 designated today be extended so that
 existing regulated MS4s would not have
 to modify their permit in the middle of
 their permit term, provided that permit
 renewal would occur within a
 reasonable time (12 to 18 months) of the
 deadline. In response, EPA notes that
 today's rule allows operators of newly
 designated small MS4s up to three years
 and 90 days from the promulgation of
 today's rule to submit an application to
 be covered under the permit issued to
 an already regulated MS4. The
 permitting authority has a reasonable
 time after receipt of the application to
 modify the existing permit to include
 the newly designated source. If an
 existing MS4's permit is up for renewal
 in the near future, the operator of a
 newly designated small MS4 may take
 that into account when timing its
 application and the NPDES permitting
 authority may take that into account
 when processing the  application.
  Another commenter suggested that
 the rule should include a provision to
 allow permit application requirements
 for smaller MS4s designated today to be
 determined by the permitting authority
 to account for the particular needs/
 wants of an already regulated MS4
 operator. EPA does not believe that the
 regulations should specifically require
 this approach. When negotiating
 whether to include a  newly designated
 MS4 in its program, the already
 regulated MS4 operator may require the
 newly designated MS4's operator to
 provide any information that is
 necessary.
  The co-permitting approach allows
small MS4s to take advantage of existing
programs to ease the burden of creating
their own programs. The operators of
regulated small MS4s, however, may
find it simpler to apply for a program
under today's rule, and to identify the
medium or large MS4 operator that is
 implementing portions of its § 122.34(b)
 minimum measures.

 d. Evaluation and Assessment
   Under today's rule, operators of
 regulated small MS4s are required to
 evaluate the appropriateness of their
 identified BMPs and progress toward
 achieving their identified measurable
 goals. The purpose of this evaluation is
 to determine whether or not the MS4 is
 meeting the requirements of the
 minimum control measures. The NPDES
 permitting authority is responsible for
 determining whether and what types of
 monitoring needs to be conducted and
 may require monitoring in accordance
 with State/Tribe monitoring plans
 appropriate to the watershed. EPA does
 not encourage requirements for "end-of-
 pipe" monitoring for regulated small
 MS4s. Rather, EPA encourages
 permitting authorities to carefully
 examine existing ambient water quality
 and assess data needs. Permitting
 authorities should consider a
 combination of physical, chemical, and
 biological monitoring or the use of other
 environmental indicators such as
 exceedance frequencies of water quality
 standards, impacted dry weather flows,
 and increased flooding frequency.
 (Claytor, R. and W. Brown. 1996.
 Environmental Indicators to Assess
 Storm Water Control Programs and
 Practices. Center for Watershed
 Protection, Silver Spring, MD.) Section
 ILL., Water Quality Issues, discusses
 monitoring in greater detail.
  As recommended by the
 Intergovernmental Task Force on
 Monitoring Water Quality (ITFM), the
 NPDES permitting authority is
 encouraged to  consider the following
 watershed objectives in determining
 monitoring requirements: (1) To
 characterize water quality and
 ecosystem health in a watershed over
 time, (2) to determine causes of existing
 and future water quality and ecosystem
 health problems in a watershed and
 develop a watershed management
 program, (3) to assess progress of
 watershed management program or
 effectiveness of pollution prevention
 and control practices, and (4) to support
 documentation of compliance with
 permit conditions and/or water quality
 standards. With these objectives in
 mind, the Agency encourages
 participation in group monitoring
programs that can take advantage of
 existing monitoring programs
 undertaken by a variety of governmental
 and nongovernental entities. Many
 States may already have a monitoring
program in effect on a watershed basis.
The ITFM report is included in the
 docket for today's rule
 (Intergovernmental Task Force on
 Monitoring Water Quality. 1995. The
 Strategy for Improving Water-Quality
 Monitoring in the United States: Final
 Report of the Intergovernmental Task
 Force on Monitoring Water Quality.
 Copies can be obtained from: U.S.
 Geological Survey, Reston, VA.).
  EPA expects that many types of
 entities will have a role in supporting
 group monitoring activities—including
 federal agencies, State agencies, the
 public, and various classes or categories
 of point source dischargers. Some
 regulated small MS4s might be required
 to contribute  to such monitoring efforts.
 EPA expects, however, that their
 participation in monitoring activities
 will be relatively limited. For purposes
 of today's rule, EPA recommends that,
 in general,  NPDES permits for small
 MS4s should not require the conduct of
 any additional monitoring beyond
 monitoring that the small MS4 may be
 already performing. In the second and
 subsequent permit terms, EPA expects
 that some limited ambient monitoring
 might be appropriately required for
 perhaps half of the regulated small
 MS4s. EPA expects that such
 monitoring will only be done in
 identified locations for relatively few
 pollutants of concern. EPA does not
 anticipate "end-of-pipe" monitoring
 requirements for regulated small MS4s.
  EPA received a wide range of
 comments on this section of the rule.
 Some commenters believe that EPA
 should require monitoring; others want
 a strong statement that the newly
 regulated small MS4s should not be
 required to monitor. Many commenters
 raised questions about exactly what EPA
 expects MS4s to do to evaluate and
 assess their BMPs. EPA has
 intentionally written today's rule to
 provide flexibility to both MS4s and
 permitting authorities regarding
 appropriate evaluation and assessment.
 Permitting authorities can specify
 monitoring or other means of evaluation
 when writing permits.  If additional
 requirements  are not specified, MS4s
 can decide what they believe is the most
 appropriate way to evaluate their storm
 water management program. As
 mentioned above, EPA expects that the
 necessity for monitoring and its extent
 may change from permit cycle to permit
 cycle. This  is  another reason for making
the  evaluation and assessment rule
requirements  very flexible.
  i. Recordkeeping. The NPDES
permitting authority is required to
 include at least the minimum
appropriate recordkeeping conditions in
 each permit. Additionally, the NPDES
permitting authority can specify that
permittees develop, maintain, and/or

-------
68770   Federal Register/Vol. 64, No.  235/Wednesday,  December 8, 1999/Rules and Regulations
submit other records to determine
compliance with permit conditions. The
MS4 operator must keep these records
for at least 3 years but is not required
to submit records to the NPDES
permitting authority unless specifically
directed to  do so. The MS4 operator
must make  the records, including the
storm water management program,
available to the public at reasonable
times during regular business hours (see
40 CFR 122.7 for confidentiality
provision).  The MS4 operator is also
able to assess a reasonable charge for
copying and to establish advance notice
requirements for members of the public.
  EPA received a comment that
questioned EPA's authority to require
MS4s to make their records available to
the public. EPA disagrees with the
commenter and believes that the CWA
does give EPA the authority to require
that MS4 records be available. It is also
more practical for the public to request
records directly from the MS4 than to
request them from EPA who would then
make the request to the MS4. Based on
comments,  EPA revised the proposed
rule so as not to limit the time for
advance notice requirements to 2
business days.
  ii. Reporting. Under today's rule, the
operator of a regulated small MS4 is
required to submit annual reports to the
NPDES permitting authority for the first
permit term. For subsequent permit
terms, the MS4 operator must submit
reports in years 2 and 4 unless the
NPDES permitting authority requires
more frequent reports. EPA received
several comments supporting this
timing for report submittal. Other
commenters suggested that annual
reports during the first permit cycle are
too burdensome and not necessary. EPA
believes that annual reports are needed
during the first 5-year permit term to
help permitting authorities track and
assess the development of MS4
programs, which should be established
by the end of the initial term.
Information contained in these reports
can also be used to respond to public
inquiries.
  The report must include (1) the status
of compliance with permit conditions,
an assessment of the appropriateness of
identified BMPs and progress toward
achieving measurable goals for each of
the minimum control measures, (2)
results of information collected and
analyzed, including monitoring data, if
any, during the reporting period, (3) a
summary of what storm water activities
the permittee plans to undertake during
the next reporting cycle, and (4) a  .
change in any identified measurable
goal(s) that apply to the program
elements.
  The NPDES permitting authority is
encouraged to provide a brief two-page
reporting format to facilitate compiling
and analyzing the data from submitted
reports. EPA does not believe that
submittal of a brief annual report of this
nature is overly burdensome, and has
not changed the required reporting time
frame from the proposal. The permitting
authority will use the reports in
evaluating compliance with permit
conditions and, where necessary, will
modify the permit conditions to address
changed conditions.
  Hi. Permit-As-A-Shield. Section
122.36 describes the scope of
authorization (i.e. "permit-as-a-shield")
under an NPDES permit as provided by
section 402(k) of the CWA. Section
402 (k) provides that compliance with an
NPDES permit is deemed compliance,
for purposes of enforcement under CWA
sections 309 and 505, with CWA
sections 301, 302, 306, 307, and 403,
except for any standard imposed under
section 307 for toxic pollutants
injurious to human health.
  EPA's Policy Statement on Scope of
Discharge Authorization and Shield
Associated with NPDES Permits,
originally issued on July 1,1994, and
revised on April 11,1995, provides
additional information on this matter.
e. Other Applicable NPDES
Requirements
  Any NPDES permit issued to an
operator of a regulated small MS4 must
also include other applicable NPDES
permit requirements and standard
conditions, specifically the applicable
requirements and  conditions at 40 CFR
122.41 through 122.49. Reporting
requirements for regulated small MS4s
are governed by §  122.34 and not the
existing requirements for medium and
large MS4s at § 122.42(c). In addition,
the NPDES permitting authority is
encouraged to consult the Interim
Permitting Approach, issued on August
1,1996. The discussion on the Interim
Permitting Approach in Section II.L.l,
Water Quality Based Effluent Limits,
provides more information. The
provisions of §§ 122.41 through 122.49
establish permit conditions and
limitations that are broadly applicable
to  the entire range of NPDES permits.
These provisions should be interpreted
in a manner that is consistent with
provisions that address specific classes
or categories of discharges. For example,
§ 122.44(d) is a general requirement that
each NPDES permit shall include
conditions to meet water quality
standards. This requirement will be met
by the specific approach outlined in
today's rule for the implementation of
BMPs. BMPs are the most appropriate
form of effluent limitations to satisfy
technology requirements and water
quality-based requirements in MS4
permits (see the introduction to Section
II.H.3, Municipal Permit Requirements,
Section II.H.S.h, Reevaluation of Rule,
and the discussion of the Interim
Permitting Policy in Section II.L.l.
below).

f. Enforceability
  NPDES permits are federally
enforceable. Violators may be subject to
the enforcement actions and penalties
described in CWA sections 309, 504,
and 505 or under similar water
pollution enforcement provisions of
State, tribal or local law. Compliance
with a permit issued pursuant to section
402 of the Clean Water Act is deemed
compliance, for purposes of sections
309 and 505, with sections 301, 302,
306, 307, and 403 (except any standard
imposed under section  307 for toxic
pollutants injurious to human health).
g. Deadlines
  Today's final rule includes
"expeditious deadlines" as directed by
CWA section 402{p)(6). In proposed
§ 122.26(e), the permit application for
the "ISTEA" facilities was maintained
as August 7, 2001 and the permit
application deadline for storm water
discharges associated with other
construction activity was established as
3 years and 90 days from the  final rule
date. In proposed § 122.33(c)(l),
operators of regulated small MS4s were
required to seek permit coverage within
3 years and 90 days from the  date of
publication of the final  rule. In
proposed § 122.33(c)(2), operators of
regulated small  MS4s designated by the
NPDES permitting authority on a local
basis under § 122.32(a)(2) must seek
coverage under an NPDES permit within
60 days of notice, unless the NPDES
permitting authority specifies a later
date.
  In order to increase the clarity of
today's final rule, EPA has changed the
location of some of the above
requirements. All application deadlines
for both Phase I and Phase II are now
listed or referenced in § 122.26(e).
Section 122.26(e)(l) contains the
deadlines for storm water associated
with industrial activity. Paragraph (i)
has been changed to correct a
typographical error. Paragraph (ii) has
been revised to reflect the changed
application date for "ISTEA" facilities.
(See discussion in section 1.3, ISTEA
Sources). The application deadline for
storm water discharges associated with
other construction activity is now in a
new § 122.26(e)(8). The application
deadline for regulated small MS4s

-------
            Federal Register/Vol. 64, No.  235/Wednesday, December 8,  1999/Rules and Regulations    68771
 remains in § 122.33(c) because this
 section is written in "readable
 regulation" format, but it is also
 described in a new § 122.26(e}(9).
   Under today's rule, permitting
 authorities are allowed up to 3 years to
 issue a general permit and MS4s
 designated under § 122.32(a)(l) are
 allowed up to 3 years and 90 days to
 submit a permit application. Operators
 of regulated small MS4s that choose to
 be a co-permittee with an adjoining MS4
 with an existing NPDES storm water
 permit must apply for a modification of
 that permit within the same time frame.
 Several commenters stated that 90 days
 was not adequate time to submit an
 NOI. This might be true if facilities did
 not start developing their storm water
 program until publication of their
 general permit. In fact, municipalities
 should start developing their storm
 water program upon publication of
 today's final rule, if they have not
 already done so. Municipalities that are
 uncertain if they fall within the
 urbanized area should ask their
 permitting authority. EPA believes that
 municipalities should not automatically
 take three years and 90 days to develop
 a program and submit their NOI. Three
 years is the maximum amount of time
 to issue a general permit. MS4s that are
 automatically designated under today's
 rule may have less than 3 years and 90
 days if the permitting authority issues a
 permit that requires submission of NOIs
 before that time. EPA encourages States
 to modify their NPDES program to
 include storm water and issue their
 permits as soon as possible. It is
 important for permitting authorities to
 keep their municipalities informed of
 their progress in developing or
 modifying their NPDES storm water
 requirements.
  EPA recognizes that MS4s brought
 into the program due to the 2000 Census
 calculations do not have as much time
 to develop  a program as those already
 designated from the 1990 Census.
 However, the official Bureau of the
 Census urbanized area calculation for
 the 2000 Census is expected to be
 published in the Federal Register in the
 spring of 2002, which should give the
 potentially affected MS4s adequate time
 to prepare for compliance under the
 applicable permit. However, if the
 publication of this information is
 delayed, MS4s in newly designated
 urbanized areas will have 180 days'from
 the time the new designations are
 published to submit an NOI, consistent
 with the time frame for other regulated
 MS4s that are designated  after
promulgation of the rule.
  The proposed application deadline for
MS4s designated under § 122.32(a)(2)
 was within 60 days of notice. Many
 commenters stated that 60 days does not
 provide adequate time for the
 preparation of an NOI or permit
 application. EPA agrees that newly
 designated MS4s may not be aware that
 they might be designated since the
 permitting authority could take several
 years to develop designation criteria.
 EPA has decided that the application
 time frame for these facilities should be
 consistent with the 180 days allowed for
 facilities designated under
 §§ 122.26(a)(9)(i)(C) and (D). Section
 122.33(c)(2) of today's final rule
 contains the modified time frame of 180
 days to apply for coverage.
 h. Reevaluation of Rule
   The municipal caucus of the Storm
 Water Phase II FACA Subcommittee
 asked EPA to demonstrate its
 commitment to revisit the municipal
 requirements of today's rule and make
 changes where necessary after
 evaluating the storm water program and
 researching the effectiveness of
 municipal BMPs. In § 122.37 of today's
 final rule, EPA commits to revisiting the
 regulations for the municipal storm
 water discharge control program after
 completion of the first two permit terms.
 EPA intends to use this time to work
 closely with stakeholders on research
 efforts. Gathering and analyzing data
 related to the storm water program,
 including data regarding the
 effectiveness of BMPs, is critical to
 EPA's storm water program evaluation.
 EPA does not intend to change today's
 NPDES municipal storm water program
 until the end of this period, except
 under the following circumstances: a
 court decision requires changes; a
 technical change is necessary for
 implementation; or the CWA is
 modified, thereby requiring changes.
 After careful analysis, EPA might also
 consider changes from consensus-based
 stakeholder requests regarding
 requirements applicable to newly
 regulated MS4s. EPA will apply the
 August 1,1996, Interim Permitting
 Approach to today's program during
 this interim period and encourages all
 permitting authorities to use this
 approach in municipal storm water
 permits for newly regulated MS4s and
 in determining MS4 permit
 requirements under a TMDL approach.
After careful consideration of the data,
EPA will make modifications as
necessary.
  EPA received comments that
supported waiting two permit cycles
before re-evaluating the rule and other
 comments that requested re-evaluation
much sooner. EPA anticipates two full
permit cycles are necessary to obtain
 enough data to significantly evaluate the
 rule. The re-evaluation time frame of 13
 years from today remains as proposed.

 I. Other Designated Storm Water
 Discharges

 1. Discharges Associated with Small
 Construction Activity
   Section 122.26(b)(15) of today's rule
 designates certain construction
 activities for regulation as "storm water
 discharges associated with small
 construction activity." Specifically,
 storm water discharges from
 construction activity equal to or greater
 than 1 acre and less than 5 acres are
 automatically designated except in
 those circumstances where the operator
 (i.e., person responsible for discharges
 that might occur) certifies to the
 permitting authority that one of two
 specific waiver circumstances
 (described in section b. below) applies.
 Sites below one acre may be designated
 under § 122.26(b)(15)(ii) where
 necessary to protect water quality.
  Today's rule regulates these
 construction-related storm water
 sources under CWA section 402(p)(6) to
 protect water quality rather than under
 CWA section 402(p)(2). Designation
 under 402(p)(6) gives States and EPA
 the flexibility to waive the permit
 requirement for construction activity
 that is not likely to impair water quality,
 and to designate additional sources
 below one acre that are likely to cause
 water quality impairment. Thus, the one
 acre threshold of today's rule is not an
 absolute threshold like the five acre
 threshold that applies under the existing
 storm water rule.
  Today's rule regulating certain storm
 water discharges from, construction
 activity disturbing less than 5 acres is
 consistent with the 9th Circuit remand
 in NRDCv. EPA, 966 F.2d 1292 (9th Cir.
 1992). In that case, the court remanded
 portions of the existing  storm water
 regulations related to discharges from
 construction sites. The existing Phase I
 regulations define "storm water
 discharges associated with industrial
 activity" to include storm water
 discharges from construction sites
 disturbing 5 acres or more of total land
 area (see 40 CFR 122.26(b)(14)(x)). In its
 decision, the court concluded that the 5-
acre threshold was improper because
the Agency had failed to identify
information "to support its perception
that construction activities on less than
5 acres are non-industrial in nature"
 (966 F.2d at 1306). The court remanded
the exemption to EPA for further
proceedings (966 F.2d at 1310). EPA's
objectives in today's action include an
effort to (1) address the  9th Circuit

-------
68772    Federal Register/Vol. 64, No.  235/Wednesday, December  8, 1999/Rules .and Regulations
remand to reconsider regulation of
storm water discharges from
construction activities that disturb less
than 5 acres of land, (2) address water  •
quality concerns associated with such
activities, and (3) balance conflicting
recommendations and concerns of
stakeholders in the regulation of
additional construction activity.
  EPA responded to the Ninth Circuit's
decision by designating discharges from
construction activities that disturb
between 1 and 5 acres as "discharges
associated with small construction
activity" under CWA section 402(p)(6),
rather than as  "discharges associated
with industrial activity" under CWA
section 402(p)(2)(B). Although a size
criterion alone may be an indicator of
whether runoff from construction sites
between 1 and 5 acres is "associated
with industrial activity," the Agency is
instead relying on a size threshold in
tandem with provisions that allow for
designations and waivers based on
potential for "predicted water quality
impairments" to regulate construction
sites between 1 and 5 acres under CWA
section 402(p)(6). This  approach was
chosen by the  Agency for the sake of
simplicity and certainty and, most
importantly, to protect water quality
consistent with the mandate of CWA
section 402(p)(6). Today's rule also
includes extended application deadlines
for this new category of dischargers
under the authority of CWA section
402(p)(6) (see § 122.26(e)(8) of today's
rule).
  In today's rule, EPA is regulating
storm water discharges from additional
construction sites to better protect the
Nation's waters, while remaining
sensitive to a concern that the Agency
should not regulate discharges from
construction sites that might not or do
not have adverse water quality impacts.
EPA believes that today's rule will
successfully accomplish this objective
by establishing a 1-acre threshold
nationwide that includes the flexibility
to allow the permitting authority to both
waive requirements for discharges from
sites that are not expected to cause
adverse water quality impacts and to
designate discharges from sites below 1-
acre based on adverse water quality
impacts.
  In addition to the diminishing water
quality benefits of regulating all sites
below one acre, the Agency relied on
practical considerations in establishing
a one acre threshold and not setting a
lower threshold. Regardless of the
threshold established by EPA, a NPDES
permit can only be required if a
construction site has a point source
discharge. A point source discharge
means that pollutants are added to
waters of the United States through a
discernible, confined, discrete
conveyance. "Sheet flow" runoff from a
small construction site would not result
in a point source discharge unless and
until it channelized. As the amount of
disturbed land surface decreases,
precipitation is less likely to channelize
and create a "point source" discharge
(assuming the absence of steep slopes or
other factors that lead to increased
channelization). Categorical designation
of very small sites may create confusion
about applicability of the NPDES
permitting program to those sites. EPA's
one acre threshold reflects, in part, the
need to recognize that smaller sites are
less likely to result in point source
discharges. Of course, the NPDES
permitting authority could designate
smaller sites (below one acre, assuming
point source discharges occur from the
smaller designated sites) for regulation
if a watershed or other local assessment
indicated the need to do so. The Phase
II rule includes this designation
authority at 40 CFR 122.26(a)(9)(i)(D)
and (b)(15)(ii).
  The one acre threshold also provides
an administrative tool for more easily
identifying those sites that are identified
for coverage by the rule (but may receive
a waiver) and those that are not
automatically covered (but may be
designated for inclusion). Although all
construction sites less than five acres
could have a significant water quality
impact cumulatively, EPA is
automatically designating for permit
coverage only those storm water
discharges from construction sites that
disturb land equal to or greater than one
acre. Categorical regulation of
discharges from construction below this
one acre threshold would overwhelm
the resources of permitting authorities
and might not yield corresponding
water quality benefits. Construction
activities that disturb less than one acre
make up, in total, a very small
percentage of the total land disturbance
from construction nationwide. The one
acre threshold is reasonable for
accomplishing the water quality goals of
CWA section 402(p)(6) because it results
in 97.5% of the total acreage disturbed
by construction being designated for
coverage by the NPDES storm water
program, while excluding from
automatic coverage the numerous
smaller sites that represent 24.7% of the
total number of construction sites.
  Some commenters believed that EPA
has not adequately identified water
quality problems associated with storm
water discharges from construction
activity disturbing less than five acres.
Other commenters believed that storm
water discharges from small
construction activity is a significant
water quality problem nationwide.
Section I.E.3, Construction Site Runoff,
provides a detailed discussion of
adverse water quality impacts resulting
from construction site storm water
discharges. EPA is regulating storm
water discharges from construction
activity disturbing between 1 and 5
acres because the cumulative impact of
many sources, and not just a single
identified source, is typically the cause
for water quality impairments,
particularly for sediment-related water
quality standards.
  Several commenters requested that
EPA regulate discharges from small
construction activity as "discharges
associated with industrial activity"
under CWA 402(p)(4) and not, as
proposed, as "storm water discharges
associated with other activity" under
CWA 402(p)(6). EPA is regulating
discharges from small construction sites
as "small construction activity" under
the authority of CWA section 402(p)(6),
rather than section 402(p)(4), to ensure
that regulation of these sources is water
quality-sensitive. CWA section 402(p)(6)
affords the opportunity for designations
and waivers of sources based on
potential for "predicted water quality
impairments." Regulation of storm
water "associated with industrial
activity" does not necessarily focus
regulation to protect water quality.
a. Scope
  The definition of "storm water
discharges associated with small
construction activity" includes
discharges from  construction activities,
such as clearing, grading, and
excavating activities, that result in the
disturbance of equal to or greater than
1 acre and less than 5 acres (see
§ 122.26(b)(15)(i)). Such activities could
include: road building; construction of
residential houses, office buildings, or
industrial buildings; or demolition
activity. The definition of "storm water
discharges associated with small
construction activity" also includes any
other construction activity, regardless of
size, designated based on the potential
for contribution to a violation of a water
quality standard or for significant
contribution of pollutants to waters of
the United States (§ 122.26(b)(15)(ii)).
This designation is made by the
Director, or in States with approved
NPDES programs, either the Director or
the EPA Regional Administrator.
  For the purposes of today's rule, the
definition of "storm water discharges
associated with small construction
activity" includes discharges from
activities disturbing less than 1 acre if
that construction activity is part of a

-------
                     Federal Register/Vol.  64, No. 235/Wednesday,  December  8,  1999/Rules and Regulations    68773
          "larger common plan of development or
          sale" with a planned disturbance of
          equal to or greater than 1 acre of land.
          A "larger common plan of development
          or sale" means a contiguous area where
          multiple separate and distinct
          construction activities are planned to
          occur at different times on different
          schedules under one plan, e.g., a
          housing development of five Y4 acre lots
          (§122.26(b)(15Ki)).
            In addition to the regulatory text for
          smaller construction, the Agency is also
          revising the existing text of
          § 122.26(b)(14)(x) to clarify EPA's
          intention regarding construction
          projects involving a larger common plan
          of development or sale ultimately
          disturbing 5 or more acres. Operators of
          such sites are required to seek coverage
          under an NPDES permit regardless of
          the number of lots in the larger plan
          because designation for permit coverage
          is based on the total amount of land area
          to be disturbed under the common plan.
          This designation attempts to address the
          potential cumulative effects of
          numerous construction activities
          concentrated in a given area.
            Several commenters asked that EPA
          allow the permitting authority to set the
          appropriate size threshold based on
          water quality studies. While EPA agrees
          that location-specific water quality
          studies provide an ideal information
          base from which to make regulatory
          decisions, today's rule establishes a
          default standard for regulation in the
          absence of location-specific studies. The
          rule does allow for deviation from the
          default standard through additional
          designations and waivers, however,
          when supported by location-specific
          water quality information. The rule
          codifies the ability of permitting
          authorities to provide waivers for sites
          greater than or equal to one acre (the
          default standard) and designate
          additional discharges from small sites
          below one acre when location-specific
          information suggests that the default 1
          acre standard is either unnecessary
          (waivers) or too limited (designations) to
          protect water quality.
            Some commenters wanted EPA to
          base the regulation of storm water
          discharges from construction sites not
          only on size, but also on the duration
          and intensity of activity occurring on
          the site. EPA believes that a national 1-
          acre threshold, in combination with
          waivers and additional designations, is
          the most effective and simplest way to
          address adverse water quality impacts
          from storm water from small
          construction sites. Moreover, as
          discussed below, the waiver for rainfall
          erosivity does account for projects of
          limited duration. EPA believes,
 however, that the intensity of activity
 occurring on-site would be a very
 difficult condition to quantify.
   Many commenters requested that EPA
 maintain the 5 acre threshold from the
 existing regulations, which include
 opportunities for site-specific
 designation, as the regulatory scope for
 regulating storm water from
 construction sites, i.e., that the Agency
 not automatically regulate storm water
 discharges from sites less than 5 acres.
 Several commenters wanted
 construction requirements to be applied
 to sites smaller than 1 acre, while some
 commenters suggested alternative
 thresholds of 2 or 3 acres. The rest of the
 commenters supported the 1 acre
 threshold. None of the commenters
 presented any data or rationales to
 support a specific size threshold.
  EPA examined alternative size
 thresholds, including 0.5 acre, 1 acre, 2
 acres and 5 acres. EPA had difficulty
 evaluating the alternative size
 thresholds because, while directly
 proportional to the size of the disturbed
 site, the water quality threat posed by
 discharges from construction sites of
 differing sizes varies nationwide,
 depending on the local climatological,
 geological, geographical, and
 hydrological influences. In order to
 ensure improvements in water quality
 nationwide, however, today's rule does
 not allow various permitting authorities
 to establish different size thresholds
 except based on the waiver and
 designation provisions of the rule. EPA
 believes that the water quality impact
 from small construction sites is as high
 as or higher than the impact from larger
 sites on a per acre basis. By selecting the
 1 acre size threshold and coupling it
 with waivers and additional
 designations, EPA is seeking to
 standardize  improvement of water
 quality on a national basis while
 providing permitting authorities with
 the opportunity to designate those
 unregulated activities causing water
 quality impairments regardless of site
 size, as well as to waive requirements
 when information demonstrates that
 regulation is unnecessary.
  EPA recognizes that the size criterion
 alone may not be the most ideal
 predictor of the need for regulation, but
 effective protection of water quality
 depends as much on simplicity in
 implementation as it does on the
 scientific information underlying the
regulatory criteria. The default size
 criterion of 1 acre will ensure protection
 against adverse water quality impacts
 from storm water from small
 construction sites while not
 overburdening the resources of
permitting authorities and the
 construction industry to implement the
 program to protect water quality in the
 first place.
   One commenter stated a need to
 clarify whether routine road
 maintenance is considered construction
 activity for the purpose of today's rule.
 The NPDES general permit for
 discharges from construction sites larger
 than 5 acres defined "commencement of
 construction" as the initial disturbance
 of soils associated with clearing,
 grading, or excavating activities or other
 construction activities  (63 FR 7913). For
 construction sites disturbing less than 5
 acres, EPA does not consider
 construction activity to include routine
 maintenance performed to maintain the
 original line and grade, hydraulic
 capacity, or original purpose of the
 facility.
   Two commenters believed that the
 Multi-Sector General Permit for storm
 water discharges from industrial
 activities (MSGP) (60 FR 50804) already
 applies to storm water discharges from
 construction activities at oil and gas
 exploration and production sites and
 asked for a clarification on this issue.
 Commenters also requested a single
 general permit to authorize both
 industrial storm water discharges and
 construction  site discharges which
 occur at the same industrial site.
   Currently, when construction activity
 disturbing more than 5 acres occurs on
 an industrial site covered by the MSGP,
 authorization under a separate NPDES
 construction permit is needed because
 the MSGP does not include the
 "construction" industrial sector. While
 the MSGP does address sediment and
 erosion control, it is not as specific as
 the NPDES general permit for storm
 water discharges from construction
 activities disturbing more than 5 acres.
 Though permitting authorities could
 conceivably develop a single general
 permit to authorize storm water
 discharges associated with construction
 activity at these industrial facilities, the
 commenter's request is not addressed by
 today's rulemaking. When today's rule
is implemented through general permits
 (to be issued later), the permitting
 authority will have discretion whether
 or not to incorporate the permit
 requirements for both the industrial
 storm water discharges and construction
 site storm water discharges into a single
general permit. This type of request
 should be addressed to the permitting
 authority.
  One commenter suggested that
 discharges from small construction sites
should be regulated through a "self-
 implementing rule" approach. While
today's rule is not a self-implementing
rule, it does add § 122.28(b)(2)(v), which
_

-------
 68774    Federal Register/Vol. 64, No.  235/Wednesday, December  8,  1999/Rules  and Regulations
 gives the permitting authority the
 discretion to authorize a construction
 general permit for sites less than 5 acres
 without submitting a notice of intent.
 Such non-registration general permits
 function similarly to self-implementing
 rules, but are, in fact, permits. Today's
 rule will be implemented through
 NPDES permits rather than self-
 implementing regulations to capitalize
 on the compliance, tracking,
 enforcement, and public participation
 associated with NPDES permits (see
 discussion in section II.C).
   Other commenters believed that only
 the permitting authority should regulate
 construction site storm water discharges
 (under a NPDES permit) and that a
 small MS4 operator's regulation of
 storm water discharges associated with
 construction (under the small MS4
 NPDES storm water program) is
 redundant. EPA disagrees  that control
 measure implementation by the NPDES
 authority and the small MS4 operator is
 redundant. To the extent the two efforts
 overlap, today's rule provides for
 consolidation and coordination of
 substantive requirements via
 incorporation by reference permitting.
 Small MS4s operators may choose to
 impose more prescriptive requirements
 than an NPDES permitting authority
 based on localized water quality needs.
 In those cases, EPA intends that the
 substantive requirements from the small
 MS4 program should apply as the
 NPDES permit requirements for the
 construction site discharger. In cases
 where a small MS4 program does not
 prioritize and focus on storm water from
 construction sites (beyond the small
 MS4 minimum control measure in
 today's rule, which does not require the
 small MS4 operator to control
 construction site discharges in a manner
 as prescriptive as is expected for
 discharges regulated under NPDES
 permits), the Agency intends that the
 NPDES general permit will provide the
 substantive standards applicable to the
 construction site discharge. EPA does
 anticipate, however, that
 implementation of MS4 programs to
 address construction site runoff within
 their jurisdiction will enhance overall
 NPDES compliance by construction site
 dischargers. EPA also notes that under
 § 122.35(b), the permitting authority
 may recognize its own program to
 control storm water discharges from
 construction sites in lieu of requiring
such a program in an MS4's NPDES
permit, provided that the permitting
authority's program satisfies the
requirements of § 122.34(b)(4),
including, for example, procedures for
site plan reviews and consideration of
 information submitted by the public on
 individual construction sites in each
 jurisdiction required to be covered by
 the program.

 b. Waivers
   Under § 122.26(b)(15)(i) of today's
 rule, NPDES permitting authorities may
 waive today's requirement for
 construction site operators to obtain a
 permit in two circumstances. The first
 waiver is intended to apply where little
 or no rainfall is expected during the
 period of construction. The second
 waiver may be granted when a TMDL or
 equivalent analysis indicates that
 controls on construction site discharges
 are not needed to protect water quality.
   The first waiver is based on "low
 predicted rainfall erosivity" which can
 be found using tables of rainfall-runoff
 erosivity (R) values published for each
 region in the U.S. R factors are
 published in the U.S. Department of
 Agriculture (USDA) Agricultural
 Handbook 703 (Renard, K.G., Foster,
 G.R., Weesies, G.A., McCool, O.K., and
 D.C. Yoder. 1997. Predicting Soil
 Erosion by Water: A Guide to
 Conservation Planning with the Revised
 Universal Soil Loss Equation (RUSLE).
 U.S. Department of Agriculture
 Handbook 703). The R factor varies
 based on the time during the year when
 construction activity occurs, where in
 the country it occurs, and how long the
 construction activity lasts. The
 permitting authority may determine,
 using Handbook 703, which times of
 year, if any, the waiver opportunity is
 available for construction activity. EPA
 will provide assistance either through
 computer programs or the World Wide
 Web on how to determine whether this
 waiver applies for a particular
 geographic area and time period.
 Application of this waiver for regulatory
 purposes will be determined by the
 authorized NPDES authority. This
 waiver is discussed further in the
 following section titled Rainfall-
 Erosivity Waiver.
  The second waiver is based on a
 consideration of ambient water quality.
This waiver is available after a State or
EPA develops and implements TMDLs
 for the pollutant(s) of concern from
 storm water discharges associated with
 construction activity. This waiver is also
 available for sites discharging to non-
 impaired waters that do not require
TMDLs, when an equivalent analysis
has determined allocations for small
construction sites for the pollutant(s) of
concern or determined that such
allocations are not needed to protect
water quality based on consideration of
existing in-stream concentrations,
expected growth  in pollutant
 contributions from all sources, and a
 margin of safety. The Agency envisions
 an equivalent analysis that would
 demonstrate that water quality is not
 threatened by storm water discharges
 from small construction activity. This
 waiver is discussed further below in the
 sections titled TMDL Waiver and Water
 Quality Issues.
   The proposed rule included a waiver
 based on "low predicted soil loss." This
 waiver provision would have been
 applicable on a case-by-case basis where
 the annual soil loss rate for the period
 of construction for a site, using the
 Revised Universal Soil Loss Equation
 (RUSLE), would be less than 2 tons/
 acre/year. The annual soil loss rate of
 less than 2 tons/acre/year would be
 calculated through the use of the RUSLE
 equation, assuming the constants of no
 ground cover and no runoff controls in
 place.
   Several commenters found the low
 soil loss waiver too complex and
 impractical, and stated that expertise is
 not available at the local level to prepare
 and evaluate eligibility for the waiver.
 Another commenter questioned whether
 two tons/acre/year was an appropriate
 threshold for predicting adverse water
 quality impacts.  Two other commenters
 said that RUSLE was never intended to
 predict off-site impacts and is not an
 indicator of potential harm to water
 quality. EPA agrees with the
 commenters on the difficulty associated
 with determining and implementing
 this waiver. Most construction site
 operators are not familiar with the
 RUSLE program, and the potential
 burden on the permitting authority,
 construction industry, USDA's Natural
 Resources Conservation Service and
 conservation districts probably would
 have been significant. The Agency has
 not included this waiver in the final
 rule.
  Two commenters asked that EPA
 allow States the flexibility to develop
 their own waiver criteria but did not
 suggest how the Agency (or affected
 stakeholders) could evaluate the
 acceptability of alternative State waiver
 criteria. Therefore, the final rule does
not provide for any such alternative
waivers. If a State does seek to develop
alternate waiver criteria, then EPA
procedures afford the opportunity for
subsequent actions, for example, under
the Project XL Program in EPA's Office
of Reinvention, which seeks cleaner,
smarter, and cheaper solutions to
environmental problems. Many
commenters suggested that EPA extend
these waivers to existing industrial
storm water regulations for construction
activity greater than 5 acres. These
construction site discharges are

-------
            Federal Register/Vol. 64, No. 235/Wednesday, December 8, 1999/Rules  and Regulations    68775
 regulated as industrial storm water
 discharges under CWA 402(p)(2) and are
 not eligible for such water quality-based
 waivers.
   Two commenters were concerned that
 waivers would create a potential for
 significant degradation of small streams.
 EPA disagrees. If small streams are
 threatened, the permitting autiiority
 would choose not to provide any
 waivers. In addition, permitting
 authorities may protect small streams by
 designating discharges from small
 construction activity based on the
 potential for contribution to a violation
 of a water quality standard or for
 significant contribution of pollutants to
 waters of the U.S.
   Two commenters asked that the
 waiver options be eliminated. They felt
 it would create a gross inequity within
 the construction community if some
 projects will not be subject to the
 requirements of today's rule. While the
 comments may be valid, EPA disagrees
 that waivers should be disallowed on
 this basis. Construction site discharges
 that qualify for a waiver from permitting
 requirements are not expected to
 present a threat to water quality, which
 is the basis for designation and
 regulation under today's rule.,
   A number of commenters suggested
 additional waivers in cases where new
 development will result in no additional
 adverse impacts to water quality as
 compared to the existing development it
 replaces. EPA believes these waivers are
 either unworkable or unnecessary. It
 would be very difficult for most
 construction operators to determine, as
 well as for other stakeholders to verify,
 on a site-by-site basis, that there is no
 potential for adverse impact to water
 quality compared to the replaced
 development.
   Other commenters proposed waivers
 in cases where a local erosion and
 sediment control program covers the
 project or a separate waiver for small
 linear utility projects. Instead of
 waivers, today's rule addresses the first
 suggestion through the qualifying
 program provision described in the
 section titled Cross-Referencing State/
 Local Erosion and Sediment Control
 Programs below. Today's rule provides
 waivers for small linear projects in so
 far as they satisfy conditions for low
 rainfall erosivity. (See
 §122.26(b)(15)(iKA).)
  Other commenters suggested waivers
based on distance to water body,
existence of vegetated buffer around
water body, slope of disturbed land, or
 if discharging to very large bodies of
water. As a result of public outreach,
EPA believes that these proposed
waivers would be generally unworkable
 for construction site dischargers and
 permitting authorities because of the
 difficulty in applying them to all small
 sites.
   One commenter mentioned that
 waivers for the R factor (rainfall-
 erosivity) and soil loss are effluent
 standards that have not been developed
 in accordance with sections 301 and 304
 of the CWA. EPA disagrees that these
 sections are relevant to the designation
 of sources in today's rule. The waiver
 provisions in this section of the rule are
 jurisdictional because they affect the
 scope of the universe of entities subject
 to the NPDES program. Therefore, the
 waiver provisions are not themselves
 substantive control standards
 implemented through NPDES permits,
 and thus, not subject to the statutory
 criteria in sections 301 and 304.
   Another commenter stated that  :
 waivers would allow exemptions to the
 technology based requirements and
 would thus be inconsistent with the
 two-fold approach of the  CWA (a
 technology based minimum and a water
 quality based overlay). EPA
 acknowledges that the CWA does not
 generally provide for waivers for the
 Act's technology-based requirements.
 The waiver provisions do not create
 exemptions from technology-based
 standards that apply to NPDES
 dischargers; they provide, exemption
 from the underlying requirement for an
 NPDES permit in the first place.
 Protection of water quality is the reason
 these smaller sites are designated for
 regulation under NPDES.  The Act's two
 fold approach imposes more stringent
 water quality based effluent limitations
 when technology-based limitations
 applicable to regulated dischargers are
 insufficient to  meet water quality
 standards. Under today's  rule, water
 quality protection is the basis for
 determining which of the unregulated
 sources should be regulated at all. Thus,
 today's rule is entirely consistent with
 the Act's two fold approach.
  /. Rainfall-Erosivity Waiver. The
 rainfall-erosivity waiver under
 § 122.26(b)(15)(i)(A) is intended to
 exempt the requirements  for a permit
 when and where negligible rainfall/
runoff-erosivity is expected. In the
 development of the Universal Soil Loss
Equation, analysis of data indicated that
when factors other than rainfall are held
 constant, soil loss is directly
proportional to a rainfall factor
 composed of total storm kinetic energy
times the maximum 30 minute
 intensity. The average annual sum of the
storm energy and intensity values for an
area comprise the R factor—the rainfall
erosivity index. A detailed explanation
of the R factor can be found in
 Predicting Soil Erosion by Water: A
 Guide to Conservation Planning With
 the Revised Universal Soil Loss
 Equation (RUSLE) (USDA, 1997).
   This waiver is time-sensitive and is
 dependent on when during the year a
 construction activity takes place, how
 long it lasts, and the expected rainfall
 and intensity during that time. R factors
 vary based on location. EPA anticipates
 that this waiver opportunity responds to
 concerns about the requirement for a
 permit when it is not expected to rain,
 especially in the arid areas of the U.S.
 Under today's rule, the permitting
 authority could waive the requirements
 for a permit for time periods when  the
 rainfall-erosivity factor ("R" in RUSLE)
 is less than five during the period of
 construction. For the purposes of
 calculating this waiver, the period of
 construction  activity starts at the time of
 initial disturbance and ends with the
 time of final stabilization. The operator
 must submit a written certification  to
 the Director in order to apply for such
 a waiver. EPA believes that those areas
 receiving negligible rainfall during
 certain times of the year are unlikely to
 have storm events causing discharges
 that could adversely impact receiving
 streams. Consequently, BMPs would not
 be necessary on those smaller sites. This
 waiver is most applicable to  projects of
 short duration and to the arid regions of
 the country where the occurrence of
 rainfall follows a cyclic pattern—
 between no rain and extremely heavy
 rain. EPA review of rainfall records for
 these areas indicates that, during
 periods of the year when the number of
 events and quantity of rain are low,
 storm water discharges from the smaller
 construction sites regulated under
 today's rule should be minimal.
   Some commenters supported the use
 of the R factor as a waiver, while others
 felt that a waiver based on rainfall
 statistics ignores the fact that it may rain
 on any given  day and it is the
 cumulative effect of wet weather
 discharges which cause water quality
 impairments. A commenter also asked
 what happens in "El Nino" years when
 significantly more rainfall than normal
 occurs. Another commenter also
 expressed concern that this waiver was
 not based on a measured water quality
 impact, but instead on an indicator of
 potential impact. In response to the
 previous comments, EPA notes that,
under CWA 402(p)(6), sources-are
 designated on their potential for adverse
 impact. Designation under the section is
prospective, not retrospective or
remedial only. For that reason, the
waivers under today's rule also operate
prospectively. EPA wanted to waive
requirements for sites with little

-------
 68776    Federal Register/Vol. 64, No.  235/Wednesday, December 8,  1999/Rules  and Regulations
 potential to impair water quality, and
 the R factor is the most straightforward
 way to do this. The permitting
 authority, if electing to use waivers,
 could always suspend the use of
 waivers in certain areas or during
 certain times. In addition, the
 permitting authority may choose to use
 a lower R factor threshold than the one
 set by EPA. Application of this waiver
 is at the discretion of the permitting
 authority, subject only to the limitation
 that R factors cannot exceed 5.
   One commenter expressed the need
 for EPA to provide a justification for the
 threshold value used for the R factor.
 None of the commenters included any
 data to show that EPA's proposed R
 factor of 2 was either too high or too
 low. EPA is using the R factor as an
 indicator of the potential to impact
 water quality. In an effort to determine
 which R threshold should be used, EPA
 conducted additional analysis of the
 rainfall/runoff erosivity factor for 134
 sites across the country. For an R factor
 threshold of 5, approximately 12% of
 sites would be waived  if the project
 period lasted 6 months, 27% for 3
 months, 47% for 1 month, and 60% of
 sites would be waived  if the project
 lasted for only 15 days. None of the 134
 sites would be waived  if the project
 lasted an entire year. For an R factor
 threshold of 2, approximately 9% of
 sites would be waived  if the project
 period lasted 6 months, 15%  for 3
 months, 31% for 1 month, and 43% for
 15 days. For an R factor threshold of 10,
 approximately 22% of sites would be
 waived if the project period lasted 6
 months, 37% for 3 months, 60% for 1
 month, and 78% for 15 days. EPA
 believes that an R factor of 5 is an
 adequate threshold to waive
 requirements for sites because they
 would not reasonably be expected to
 impair water quality.
  EPA will develop, as part of the tool
box described in section II.A.5,
 guidance materials and computer or
 web-accessible programs to assist
 permitting authorities and construction
 site discharges in determining if any
resulting storm water discharges from
specific projects are eligible for this
waiver.
  //. Water Quality Waiver. The water
quality waiver under
 § 122.26(b)(15)(i)(B) is available where
storm water controls are not needed
based on a comprehensive, location-
specific evaluation of water quality
needs. The waiver is available based on
either an EPA-approved "total
maximum daily load" (TMDL) under
section 303(d) of the CWA that
addresses the pollutant(s) of concern or,
for sites discharging to non-impaired
 waters that do not require TMDLs, an
 equivalent analysis that has either
 determined allocations for small
 construction sites for the pollutant(s) of
 concern or determined that such
 allocations are not needed to protect
 water quality based on consideration of
 existing in-stream concentrations,
 expected growth in pollutant
 contributions from all sources, and a
 margin of safety. The pollutants of
 concern that must be addressed include
 sediment or a parameter that addresses
 sediment (such as total suspended
 solids (TSS), turbidity or siltation) and
 any other pollutant that has been
 identified as a cause of impairment of
 any water body that will receive a
 discharge from the construction activity.
 The operator must certify to the NPDES
 permitting authority that the
 construction activity will take place,
 and storm water discharges will occur,
 within the applicable drainage area
 evaluated in the TMDLs or equivalent
 analyses.
  Today's rule modifies the approach in
 the proposed rule. EPA proposed to
 allow a waiver of permit requirements
 for small construction if storm water
 controls were determined to be
 unnecessary based on "wasteload
 allocations that are part of 'total
 maximum daily loads' (TMDLs) that
 address the pollutants of concern," or "a
 comprehensive watershed plan,
 implemented for the water body, that
 includes the equivalents of TMDLs, and
 addresses the pollutants of concern."
  Commenters asked for clarification of
 the terms "comprehensive watershed
 plans" and "equivalent of TMDLs." EPA
 intended that both terms would include
 a comprehensive analysis that
 determines that controls on small
 construction sites are not needed based
 on consideration of existing in-stream
 concentrations, expected growth in
 pollutant contributions from all sources,
 and a margin of safety. Today's rule
 makes this clarification.
  One commenter pointed out that there
 are no water quality standards for
 suspended solids, the major pollutant
 expected in discharges from
 construction activity. The commenter
 asserted that no waiver would ever be
 available. Another commenter noted
 that there are no sediment criteria
 developed for streams/also making this
 waiver useless. EPA notes that a number
 of States and Tribes have water quality
 standards that address TSS, which are
 narrative in form, and that may serve as
 a basis for water quality-based effluent
 limits. As efforts to identify
 impairments and improve water quality
progress, some States may yet develop
 water quality standards for suspended
 solids. Although several TMDLs for
 sediment and related parameters have
 been established, EPA does recognize
 that currently it is extremely difficult to
 develop TMDLs for sediment. EPA is
 partially addressing this concern by
 clarifying in today's rule that the
 waivers may be based on a TMDL or
 equivalent analyses for sediment or one
 of the various pollutant parameters that
 are a proxy for sediment. These include
 TSS, turbidity and siltation.
   Other commenters noted that this
 waiver was unattainable if a TMDL or
 equivalent analysis must be available for
 every pollutant that could possibly be
 present in any amount in discharges
 from small construction sites regardless
 of whether the pollutant is causing
 water quality impairment. Commenters
 asked that EPA identify what constitutes
 the "pollutants of concern" for which a
 TMDL or its equivalent must be
 developed. EPA has revised the
 proposed rule in response to these
 concerns.
   In order for  discharges from
 construction sites under five acres to
 qualify for the water quality waiver of
 today's rule, the construction site
 operator must demonstrate that storm
 water controls are not necessary for
 sediment or a parameter that addresses
 sediment (such as TSS, turbidity or
 siltation) and any other pollutant that
 has been identified as a cause of
 impairment of any water body that will
 receive a discharge from the
 construction activity. Even if the water
 body is not currently impaired for
 sediment, today's rule requires an
 analysis of the potential impacts  of
 sediment because the storm water
 discharges from the construction
 activity will be a new source of loading
 to the water body that could constitute
 a new impairment. Because the water
 body will not necessarily have been
 included on a "303(d) list" and a TMDL
 will not necessarily be required, the rule
 continues to allow  an analysis that is
 the equivalent of a  TMDL.  The
 designation of storm water discharges
 from small construction activity for
regulation in today's rule is intended to
 control pollutants other than sediment.
This waiver provision requires a TMDL
 or equivalent analysis for a pollutant
 other than gross particulates (i.e.,
 sediment and other particulate-focused
pollutant parameters) only if the
receiving water is currently impaired for
that pollutant.
  One commenter expressed the
concern that construction operators will
not know if they are in a watershed
covered by a TMDL. To the extent this
is an operator's concern, he or she could
contact their NPDES permitting

-------
           Federal Register/Vol. 64, No.  235/Wednesday, December 8,  1999/Rules and Regulations    68777
 authority before applying for permit
 coverage to determine if receiving water
 is subject to a TMDL. Alternatively, the
 permitting authority could identify the
 TMDL (or equivalent analysis) areas in
 the general permit or another operator-
 accessible information source.
   Another commenter expressed the
 concern that a TMDL waiver is likely to
 be ineffective because the TMDL list is
 submitted only once every 2 years. By
 the time a water is listed, the activity
 may have been completed and
 stabilized. The commenter argued that,
 if a watershed is impaired due to
 sediment from construction, then storm
 water controls will still be needed,
 because small construction can only be
 waived when it is not identified  as a
 source of impairment. In response, EPA
 notes that an analysis that is the
 equivalent of a TMDL (specifically,
 equivalent to the component of a TMDL
 that comprehensively analyses existing
 ambient conditions against the
 applicable water quality standards) may
 also provide a basis for waiver from the
 default 1 acre designation. Also,  even if
 a water has been identified as impaired
 for sediment, it is possible that a site or
 category of sites may receive an
 allocation that is sufficiently high
 enough to allow discharges without
 storm water controls.
 c. Permit Process and Administration
  The operator of the construction site,
 as with any operator of a point source
 discharge, is responsible for obtaining
 coverage under a NPDES permit  as
 required by §122.21(b). The "operator"
 of the construction site, as explained in
 the current NPDES construction  general
 permit, is typically the party or parties
 that either individually or collectively
 meet the following two criteria: (1)
 Operational control over the site
 specifications, including the ability to
 make modifications in the
 specifications; and (2) day-to-day
 operational control of those activities at
 the site necessary to ensure compliance
 \vith permit conditions (63  FR 7859). If
 more than one party meets these
 criteria, then each party involved would
 typically be a co-permittee with any
 other operators. The operator could be
 the owner, the developer, the general
 contractor, or individual contractor.
 When responsibility for operational
 control is shared, all operators must
 apply.
  in today's rule, EPA is not requiring
 an NOI for NPDES general permits for
storm water discharges from
 construction activities regulated by
 § 122.26(b)(15) if the NPDES permitting
authority finds that the use of NOIs
would be inappropriate (see
 § 122.28(b)(2)(v)). Under this approach,
 the NPDES permitting authority will
 have the discretion to decide whether or
 not to require NOIs for discharges from
 construction activity less than 5 acres.
 Compared to the existing storm water
 regulation, the permitting authority thus
 has increased flexibility in program
 implementation. EPA does recommend
 the use of NOIs, however because NOIs
 track permit coverage and provide a
 useful information source to prioritize
 inspections or enforcement. Requiring
 an NOI allows for greater accountability
 by, and tracking of, dischargers. This
 simple permit application and reporting
 mechanism also allows for better
 outreach to the regulated community,
 uses an existing and familiar
 mechanism, and is consistent with the
 existing requirements for storm water
 discharges from larger construction
 activities. Today's rule does not amend
 the requirement for NOIs in general
 permits for storm water discharges from
 construction activity disturbing 5 acres
 for more. See § 122.28(b)(2)(v).
  EPA expects that the vast majority of
 discharges of storm water associated
 with small construction activity
 identified in § 122.26(b)(15) will be
 regulated through general permits. In
 the event that an NPDES permitting
 authority decides to issue an individual
 construction permit, however,
 individual application requirements for
 these construction site discharges are
 found at § 122.26{c)(l)(ii). For any
 discharges of storm water associated
 with small construction activity
 identified in § 122.26(b)(15) that are not
 authorized by a general permit, a permit
 application made pursuant to
 § 122.26(c) must be submitted to the
Director by 3 years and 90 days after
publication of the final rule.
  Some commenters expressed concern
 that linear construction projects (e.g.,
roads, highways, pipelines) that cross
 several jurisdictions will have to
 comply with multiple sets of
 requirements from various jurisdictions,
 including multiple local governments
 and States. EPA is limited in its options
to address these concerns because the
Agency cannot issue NPDES permits in
 States authorized to implement the
NPDES program nor preempt other more
stringent local and State requirements.
EPA believes, however, that the option
for incorporating by reference the State,
Tribal or local requirements (see
 discussion in Section II.I.2.d., Cross-
Referencing State/Local Erosion and
Sediment Control Programs) should
limit the administrative burden on the
operator responsible for discharges from
linear construction projects. If the
operator were to implement the most
 comprehensive of the various
 requirements for the whole project, it
 could avoid confusion due to differing
 requirements for different sections of
 the project. In addition, linear utility
 projects, which usually have a shorter
 project period, are more likely to be
 eligible for the rainfall erosivity waiver.
  One commenter stated there was no
 reason to delay the application period
 for regulated storm water discharges
 from small construction activities. The
 commenter requested that the newly
 regulated construction site discharges
 should be required to  seek permit
 coverage within 90 days, as opposed to
 3 years, of the effective date of the rule.
 The Agency does not accept this
 request. EPA anticipates that NPDES
 permitting authorities will need one to
 two years to develop adequate legal
 authority to  implement a program to
 address this new category  of discharges,
 as well as to develop and issue general
 permits. Moreover, to  ensure effective
 implementation to protect water quality,
 regulatory authorities  will need
 additional time to inform small
 construction site operators of
 requirements and provide  guidance and
 training on these requirements.
  Finally, EPA received a comment
 requesting that the three year file
 retention requirement be deleted for
 discharges from small construction
 sites. While EPA recognizes that the
 three year record retention schedule
 may be unnecessary for certain
 construction projects,  the Agency has
 determined it is necessary to retain files
 after the completion of the project to
 ensure permit compliance, including
 applicable construction site stabilization
 enabling permit termination for  such
 sites.

 d. Cross-Referencing State, Tribal or
 Local Erosion and Sediment Control
 Programs
  In developing the NPDES permit
 requirements for construction sites less
 than 5 acres, members of the Storm
Water Phase IIFACA Subcommittee
 asked EPA to try to minimize
 redundancy  in the construction  permit
 requirements. In response, today's rule
 at § 122.44(s) provides for incorporation
 of qualifying State, Tribal or local
 erosion and sediment  control program
requirements by reference  into the
 NPDES permit authorizing storm water
 discharges from construction sites
 (described under §§ 122.26(b)(15) and
 (b)(14)(x)). The incorporation by
reference approach applies not only to
the newly regulated storm  water
 discharges (from construction activity
 disturbing between 1 and 5 acres,
including designated sites, but

-------
 68778    Federal Register/Vol. 64,  No. 235/Wednesday, December 8, 1999/Rules and Regulations
 excluding waived sites) but also to
 discharges from construction activity
 disturbing 5 or more acres already
 covered by the existing storm water
 regulations.  For this latter category of
 discharges from construction activity
 disturbing 5 or more acres, the
 incorporation by reference approach
 requires that the pollutant control
 requirements from the incorporated
 program also satisfy the statutory
 standard for limitations representing
 application of the best available
 technology economically achievable
 (BAT) and best conventional pollutant
 control technology (BCT).
   For permits issued for discharges from
 small construction activity defined
 under § 122.26(b)(15), a qualifying State,
 Tribal, or local erosion and sediment
 control program is one that includes the
 program elements described under
 § 122.44(s)(l). These elements include
 requirements for construction site
 operators to implement appropriate
 erosion and sediment control BMPs,
 requirements to control waste, a
 requirement to develop a storm water
 pollution prevention plan, and
 requirements to submit a site plan for
 review. A storm water pollution
 prevention plan includes site
 descriptions, descriptions of appropriate
 control measures, copies of approved
 State, Tribal  or local requirements,
 maintenance procedures, inspection
 procedures, and identification of non-
 storm water discharges. The
 construction site's permit would require
 it to follow the requirements of the
 qualifying local program rather than
 require it to follow two different sets of
 requirements. If a partially-qualifying
 program does not have all of the
 elements described under § 122.44(s)(l),
 then the NPDES permitting authority
 may still incorporate language in the
 small construction site discharge's
 permit that requires the construction
 site operator to follow the program, but
 the construction site discharge permit
 also must incorporate the missing
 required elements in order to satisfy
 CWA requirements.
  The term "local" refers to the
 geographic area of applicability, not the
 form of government that develops and
 administers the program. Thus, a
 qualifying federal erosion and control
 program, such as certain programs
 developed and administered by the
 federal Bureau of Land Management,
 could be a qualifying local program.
  As a result  of this provision, local
 requirements will, in effect, provide the
 substantive construction site erosion
and sediment control requirements for
the NPDES permit authorization.
Therefore, by following one set of
 erosion and sediment control
 requirements, construction site
 operators satisfy both local and NPDES
 permit requirements without
 duplicative effort. At the same time,
 noncompliance with  the referenced
 local requirements will be considered
 noncompliance with  the NPDES permit
 which is federally enforceable. The
 NPDES permitting authority will, of
 course, retain the discretion to decide
 whether to include the alternative
 requirements in the general permit. EPA
 believes that this approach will best
 balance the need for consideration of
 specific local requirements and local
 implementation with the need for
 federal and citizen oversight, and will
 extend supplemental  NPDES
 requirements to control storm water
 discharges from construction sites.
   EPA developed the "incorporation by
 reference" approach based on
 implementation efforts designed by the
 State of Michigan. Michigan relies on
 localities to develop substantive
 controls for storm water discharges
 associated with construction activities
 on a localized basis. Localities,
 however, are not required to do so. In
 areas where the local  authority does not
 choose to participate,  the State
 administers the sedimentation and
 erosion control requirements. The State
 agency, as the NPDES permitting
 authority, receives an  NOI (termed
 "notice of coverage" by Michigan)
 under the general permit and tracks and
 exercises oversight, as appropriate, over
 the activity causing the storm water
 discharge. Michigan's goal under these
 procedures is to utilize the existing
 erosion and sediment  control program
 infrastructure authorized under State
 law for storm water discharge
 regulation. (See U.S. Environmental
 Protection Agency, Office of Water.
 January 7, 1994. Memo: From Michael
 B. Cook, Director OWEC, to Water
 Management Division Directors,
 Regarding the "Approach Taken by
 Michigan to Regulate Storm Water
 Discharges from Construction
 Activities.")
  Most commenters supported the
 general concept of incorporating by
 reference qualifying programs. Two
 commenters expressed concern that
 different local construction
 requirements will create an impossible
 regulatory scheme for  builders who
 work in different localities. EPA
believes that allowing  States to
 incorporate qualifying programs by
reference will minimize the differences
for builders who work in different areas
of the State. These differences already
exist, however, not only for erosion and
sediment controls, but also other aspects
 of construction. In any event, the
 criteria for qualification for localized
 programs should provide a certain
 degree of standardization for various
 localities' requirements. EPA expects
 that the new rule for construction and
 post-construction BMPs being
 developed under CWA section 304(m)
 will also encourage standardization of
 local requirements. (See discussion of
 this new rulemaking in section II.D.l,
 Federal Role of this preamble).
   Two commenters requested that an
 "incorporation by reference" should
 include permission, in writing, from the
 qualifying local program administrator
 because of a perceived extra burden on
 the referenced program. Any program
 requirements incorporated by reference
 in NPDES permits should already apply
 to construction site dischargers in the
 applicable area and therefore should not
 add any additional burden to the
 referenced program. EPA has left to the
 discretion of the permitting authority
 the decision on whether to seek
 permission from the qualifying program
 before cross-referencing it in an NPDES
 permit.
   One commenter stated that a
 qualifying local program should require
 a SWPPP. The proposed rule  defined
 the qualifying local program as a
 program the meets the minimum
 program requirements established in the
 proposed construction minimum
 control measure for small MS4s. To
 ensure consistency in the controls for
 storm water discharges between the
 larger, already regulated construction
 sites and the discharges from  smaller
 sites that will be regulated as  a result of
 today's rule, EPA has made a  change to
 define a qualifying local program as one
 that includes the elements described  in
 §122.44(s)(l). Section 122.44(s)(l)
 requires the development and
 implementation of a storm water
 pollution prevention plan as a criterion
 for qualification of local programs for
 incorporation by reference. As noted
 above, if a qualifying program does not
 include all the elements in § 122.44(s)(l)
 then the permitting authority  will need
 to specify the missing elements in order
 to rely on the incorporation by reference
 approach.
  One commenter asked what happens
 in regard to the use of qualifying
 programs when a construction site
 operator is also the qualifying local
 program operator. The provision for
 incorporation by reference applies in
this situation also. The local program
 operator will be required to comply
with requirements it has established for
 others.

e. Alternative Approaches
  EPA received a number of comments
on alternative permitting approaches.
Several commenters supported
regulating discharges only from those
construction sites within urbanized
areas. Other commenters opposed this
approach. EPA chose to address storm
water discharges from construction sites
located both within and outside
urbanized areas because of the potential
for adverse water quality impact from
storm water discharges from smaller
sites in all areas. Regulating only those
sites within urbanized areas would have
excluded a large number of potential
contributors to water quality
impairment and would not address large
areas of new development occurring on
the outer fringes of urbanized areas. In
fact, designating only small construction
discharges within urbanized areas might
create a perverse incentive for building
only outside urbanized areas.  Such an
incentive would be inconsistent with
the Agency's intention behind
designating to protect water quality. The
Agency intends that designation to
protect water quality in today's rule
should be both remedial and preventive.
  A number of commenters encouraged
EPA to cover municipal construction
activities under the small MS4 general
permit, instead of issuing a separate
NPDES construction permit to these
municipal construction projects.
Similarly, a number of commenters
supported EPA giving industrial
facilities the option of having  storm
water from construction activities on the
site covered by the industrial storm
water permit. Several other commenters
found that combining multiple permit
types under one general permit
introduced a degree of complexity
which was confusing to permittees.
Permitting authorities have the option of
combining MS4 and construction
permits or industrial  and construction
permits, however, specific requirements
for each would still need to be included
in the permit issued.  EPA agrees that
this would probably result in a more
complex and confusing permit
compared to the existing component
permits.
  Several commenters supported an
alternative for regulated small MS4s
where a local qualified program alone,
without an NPDES permit, is sufficient
to enforce compliance with construction
site discharge requirements. On the
other hand, one commenter stated that
linking the local construction erosion
and sediment control program to the
existing NPDES program for storm water
from larger construction has driven
improvements in many local programs.
Another commenter stated that the
potential fines under the NPDES
program will encourage compliance and
will be much stronger than any fines a
local program may have. EPA agrees
that the NPDES program is the best
approach to address water quality
impacts from construction sites and
provides  benefits such as accountability
and federal enforcement.
  A number of commenters supported
issuing one permit for each construction
company, instead of a permit for each
individual construction activity (also
requested for storm water discharges
from the  larger, already regulated
construction sites]. Other commenters
found that a 'licensing' program for
construction site operators would have
many problems, including identifying
who to permit and tracking information
on active sites. EPA is regulating only
the storm water discharges associated
with construction activity from small
sites, not the construction activity itself.
Separate  NPDES permits (either
individual or general permit coverage)
for construction site discharges avoid
potential problems in tracking sites and
operator accountability. Section
122.28(b)(2)(v) gives permitting
authorities the option to issue a general
permit without requiring an NOI. If an
NOI is not required for each activity,
permitting authorities could pursue
other options such as a company-wide
NOI, license instead of an NOI, or
another mechanism.

2. Other Sources
  In the Storm Water Discharges
Potentially Addressed by Phase II of the
National Pollutant Discharge
Elimination System Storm Water
Program, Report to Congress, March
1995, ("Report") submitted by EPA
pursuant to CWA  section 402(p)(5), EPA
examined the remaining unregulated
point sources of storm water  for the
potential to adversely affect water
quality. Due to very limited national
data on which to estimate pollutant
loadings  on the basis of discharge
categories, the discussion of the extent
of unregulated storm water discharges is
limited to an analysis of the number  and
geographic distribution of the
unregulated storm water discharges.
Therefore, EPA is  not designating any
additional unregulated point sources of
storm water on a nationwide, categorical
basis. Instead,  the remainder of the
sources will be regulated based on case-
by-case post-promulgation designations
by the NPDES  permitting authority.
  EPA did, however, evaluate a variety
of categories of discharges for potential
designation in the Report. EPA's efforts
to identify sources and categories of
unregulated storm water discharges for
potential designation for regulation in
today's rule started with an examination
of approximately 7.7 million
commercial, retail, industrial, and
institutional facilities identified as
"unregulated." In general, the
distribution of these facilities follows
the distribution of population, with a
large percentage of facilities
concentrated within urbanized areas
(see page 4-35 of the Report). This
examination resulted in identification of
two general classes of facilities with the
potential for discharging pollutants to
waters of the United States through
storm water point sources.
  The first group (Group A) included
sources that are very similar, or
identical, to regulated "storm water
discharges associated with industrial
activity" but that were not included in
the existing storm water regulations
because EPA used SIC codes in defining
the universe of regulated industrial
activities. By relying on SIC codes, a
classification system created to identify
industries rather than environmental
impacts from these industries
discharges, some types of storm water
discharges that might otherwise be
considered "industrial" were not
included in the existing NPDES storm
water program. The second general class
of facilities (Group B) was identified on
the basis of potential for activities and
pollutants that could contribute to storm
water contamination.
  EPA estimates that Group A has
approximately 100,000 facilities.
Discharges from facilities in this group,
which may be of high priority due to
their similarity to regulated storm water
discharges from industrial facilities,
include, for example, auxiliary facilities
or secondary activities (e.g.,
maintenance of construction equipment
and vehicles, local trucking for an
unregulated facility such as a grocery
store) and facilities intentionally
omitted from existing storm water
regulations (e.g., publicly owned
treatment works with a design flow of
less than 1 million gallons per day,
landfills that have not received
industrial waste).
  Group B consists of nearly one
million facilities. EPA organized Group
B sources into 18 sectors for the
purposes of the Report. The automobile
service sector (e.g., gas/service stations,
general automobile repair, new and
used car dealerships, car and truck
rental) makes up more than one-third of
the total number of facilities identified
in all 18 sectors.
  EPA conducted a geographical
analysis of the industrial and
commercial facilities in Groups A and

-------
 G8780    Federal Register/Vol. 64, No.  235/Wednesday, December 8,  1999/Rules  and  Regulations
 B. The geographical analysis shows that
 the majority are located in urbanized
 areas (see Section 4.2.2, Geographic
 Extent of Facilities, in the Report). In
 general, about 61 percent of Group A
 facilities and 56 percent of Group B
 facilities are located in urbanized areas.
 The analysis also showed that nearly
 twice as many industrial facilities are
 found in all urbanized areas as are
 found in large and medium
 municipalities alone.  Notable
 exceptions to this generalization
 included lawn/garden establishments,
 small unregulated animal feedlots,
 wholesale livestock, farm and garden
 machinery repair, bulk petroleum
 wholesale, farm supplies, lumber and
 building materials, agricultural
 chemical dealers, and petroleum
 pipelines, which can  frequently be
 located in smaller municipalities or
 rural areas.
  In identifying potential categories of
 sources for designation in today's
 notice, EPA considered  designation of
 discharges from Group A and Group B
 facilities. EPA applied three criteria to
 each potential category in both groups
 to determine the need for designation:
 (1) The likelihood for exposure of
 pollutant sources included in that
 category, (2) whether  such sources were
 adequately addressed by other
 environmental programs, and (3)
 whether sufficient data were available at
 this time on which to  make a
 determination of potential adverse water
 quality impacts for the category of
 sources. As discussed previously, EPA
 searched for applicable nationwide data
 on the water quality impacts of such
 categories of facilities.
  By application of the first criterion,
 the likelihood for exposure, EPA
 considered the nature of potential
 pollutant sources in exposed portions of
 such sites. As precipitation contacts
 industrial materials or activities, the
 resultant runoff is likely to mobilize and
 become contaminated by pollutants. As
 the size of these  exposed areas
 increases, EPA expects a proportional
 increase in the pollutant loadings
 leaving the site. If EPA concluded that
 a category of sources has a high
potential for exposure of raw materials,
 intermediate products, final products,
waste materials,  byproducts, industrial
 machinery, or industrial activity to
rainfall, the Agency rated that category
of sources as having "high" potential for
adverse water quality  impact. EPA's
application of the first criterion showed
that a number of Group A and B sources
have a high likelihood of exposure of
pollutants.
  Through application of-the second
criterion, EPA assessed the likelihood
 that pollutant sources are regulated in a
 comprehensive fashion under other
 environmental protection programs,
 such as programs under the Resource
 Conservation and Recovery Act (RCRA)
 or the Occupational Health and Safety
 Act (OSHA). If EPA concluded that the
 category of sources was sufficiently
 addressed under another program, the
 Agency rated that source category as
 having "low" potential for adverse
 water quality impact. Application of the
 second criterion showed that some
 categories were likely to be adequately
 addressed by other programs.
   After application of the third
 criterion, availability of nationwide data
 on the various storm water  discharge
 categories, EPA concluded that available
 data would not support any such
 nationwide designations. While such
 data could exist  on a regional or local
 basis, EPA believes that permitting
 authorities should have flexibility to
 regulate only those categories of sources
 contributing  to localized water quality
 impairments.
   EPA received comments requesting
 designation of additional industrial,
 commercial and  retail sources (e.g.
 industrial activity "look-alikes", roads,
 commercial facilities and institutions,
 and vehicle maintenance facilities) in
 the final rule, because the commenters
 believe that the data exist to support
 national designation of some of these
 sources. Other comments were received
 opposing designation of any additional
 sources. Today's rule does not designate
 any additional industrial or commercial
 category of sources either because EPA
 currently lacks information indicating a
 consistent potential for adverse water
 quality impact or because of EPA's
 belief that the likelihood of adverse
 impacts on water quality is  low, with
 some possible exceptions on a more
 local basis. Since the time the Agency
 submitted the Report, EPA has
 continued to  seek additional data and
 has requested available data from the
 FACA members.  If sufficient regional or
 nationwide data become available in the
 future, the permitting authority could at
 that time designate a category of sources
 or individual sources on a case-by-case
 basis. Therefore,  today's rule encourages
 control of storm water discharges from
Groups A and B through self-initiated,
voluntary BMPs, unless the  discharge
 (or category of discharges) is designated
 for permitting by the permitting
authority. See discussion in section I.D.,
EPA's Reports to Congress.
3. ISTEA Sources
  Provisions within the Intermodal
Surface Transportation  and Efficiency
Act (ISTEA) of 1991 temporarily
 exempted storm water discharges
 associated with industrial activity that
 are owned or operated by municipalities
 serving populations less than 100,000
 people (except for airports, power
 plants, and uncontrolled sanitary
 landfills) from the need to apply for or
 obtain a storm water discharge permit
 (section 1068(c) of ISTEA). Congress
 extended the NPDES permitting
 moratorium for these facilities to allow
 small municipalities additional time to
 comply with NPDES requirements for
 certain sources of industrial storm
 water. The August 7,1995 storm water
 final rule (60 FR 40230) further
 extended this moratorium until August
 7, 2001.  However, today's rule changes
 this deadline so that previously
 exempted industrial facilities owned or
 operated by municipalities serving
 populations less than 100,000 people,
 must now submit an application for a
 permit within 3 years and 90 days from
 date of publication of today's rule.
  EPA received comments
 recommending that permit requirements
 for municipally owned or operated
 industrial storm water discharges,
 including those previously exempt
 under ISTEA, be included in a single
 NPDES permit for all MS4 storm water
 discharges. The existing NPDES
 regulations already provide permitting
 authorities the ability to issue a  single
 "combination" permit for MS4
 discharges. However, if the permitting
 authorities chose to issue this type of
 permit, they must make sure that in
 doing so, they are not creating a double
 standard for industrial facilities  covered
 under the combination permit versus
 those covered under separate general or
 individual permits. In order to avoid
 this double standard, combination
 permits would have to contain
 requirements that are the same or very
 similar to the requirements found in
 separate MS4 and industrial permits,
 i.e., the minimum measures and other
 necessary requirements of an MS4
 permit, and the SWPPP, monitoring and
 reporting requirements, and other
 necessary requirements of an industrial
 permit. If such a combined MS4 general
permit were issued, the regulations.
 require that each discharger submit
 NOIs for their respective discharges,
 except for discharges from small
 construction activities. Flexibility exists
in developing a combination NOI which
could reduce the need to submit
 duplicative information, e.g. owner/
operator name and address. The
combination NOI would still need to
require specific information for each
separate municipally owned or operated
industrial location, including

-------
            Federal Register/Vol. 64,  No. 235/Wednesday, December 8, 1999/Rules and Regulations    68781
 construction projects disturbing 5 or
 more acres. The regulations at
 § 122.28(bK2)(ii) list the necessary
 contents of an NOI, which require: the  ,
 facility name, facility address, type of
 facility or discharge and receiving
 stream for each industrial discharge
 location. When viewed in its entirety, a
 combination permit, which by necessity
 would need to contain all elements of
 otherwise separate industrial and MS4
 permit requirements, and require NOI
 information for each separate industrial
 activity, may have few advantages when
 compared to obtaining separate MS4
 and industrial general permit coverage.
   In order to allow the permitting
 authority to issue a single storm water
 permit for the MS4 and all municipally
 owned or operated industrial facilities,
 including those previously exempt
 under ISTEA, today's rule requires
 applications for ISTEA sources within 3
 yrs and 90 days from date of publication
 of today's rule. The permitting authority
 has  the ultimate decision to determine
 whether or not a single all-
 encompassing MS4 permit is
 appropriate.
 4. Residual Designation Authority
  The NPDES permitting authority's
 existing designation authority, as well
 as the petition provisions are being
 retained. Today's rule contains two ,
 provisions related to designation
 authority at §§ 122.26(a)(9)(i)(C)  and (D).
 Subsection (C) adds designation
 authority where storm water controls
 are needed for the discharge based upon
 wasteload allocations that are part of
 TMDLs that address the pollutant(s) of
 concern. EPA intends that the NPDES
 permitting authority have discretion in
 the matter of designations based on
 TMDLs under subsection (C).
 Subsection (D) carries forward residual
 designation authority under former
 § 122.26(g), and has been modified to
 provide clarification on categorical
 designation. Under today's rule,  EPA
 and  authorized States continue to
 exercise the authority to designate
 remaining unregulated discharges
 composed entirely of storm water for
 regulation on a case-by-case basis
 (including § 123.35). Individual sources
 are subject to regulation if EPA or the
 State, as the case may be, determines
 that  the storm water discharge from the
 source contributes to a violation  of a
 water quality standard or is a significant
 contributor of pollutants to waters of the
 United States. This standard is based on
 the text of section CWA 402 (p). In
 today's rule, EPA believes, as Congress
 did in drafting section CWA
402(p)(2)(E), that individual instances of
storm water discharge might warrant
 special regulatory attention, but do not
 fall neatly into a discrete,
 predetermined category. Today's rule
 preserves the regulatory authority to
 subsequently address a source (or
 category of sources) of storm water
 discharges of concern on a localized or
 regional basis. For example, as States
 and EPA implement TMDLs, permitting
 authorities may need to designate some
 point source discharges of storm water
 on a categorical basis either locally or
 regionally in order to assure progress
 toward compliance with water quality
 standards in the watershed.
   EPA received comments asking that
 § 122.26(a)(9)(i)(D) as proposed be
 modified to  include specific language
 clarifying the permitting authority's
 ability to designate additional sources
 on a categorical basis as explained in
 the preamble to the proposed rule. One
 comment requested that the designation
 language include  "categories of sources
 on a Statewide basis." EPA agrees that
 the intent of the language may not have
 been clear regarding categorical
 designation. Today's rule modifies
 subsection (D) to clarify that the
 designation authority can be applied
 within different geographic areas to any
 single discharge (i.e., a specific facility),
 or category of discharges that are
 contributing to a violation of a water
 quality standard or are significant
 contributors of pollutants to waters of
 the United States. The added term
 "within a geographic area" allows
 "State-wide" or "watershed-wide"
 designation within the meaning of the
 terms.
  One commenter questioned the
 Agency's legal authority to provide for
 such residual designation authority. The
 stakeholder argued that the lapse of the
 October 1, 1994, permitting moratorium
 under CWA section 402(p)(l) eliminated
 the significance of the CWA section
 402(p)(2) exceptions to the moratorium,
 including the exception for discharges
 of storm water determined to be
 contributing to a violation of a water
 quality standard or a significant
 contributor of pollutants under CWA
 section 402(p)(2)(E). The stakeholder
 further argued that EPA's authority to
 designate sources  for regulation under
CWA section 402(p)(6) is limited to
storm water discharges other than those
 described under CWA section 402(p)(2).
Because CWA section 402(p)(2)(E)
 describes individually designated
 discharges, the stakeholder concluded
that regulations under CWA section
402(p)(6) cannot provide for post-
promulgation designation of individual
sources. EPA disagrees.
  First, as explained previously, EPA
anticipates that NPDES permitting
 authorities may yet determine that
 individual unregulated point sources of
 storm water discharges require
 regulation on a case-by-case basis. This
 conclusion is consistent with the
 Congress' recognition of the potential
 need for such designation under the first
 phase of storm water regulation as
 described in CWA section 402(p)(2)(E).
 Under CWA section 402(p)(2)(E),
 Congress recognized the need for both
 EPA and the State to retain authority to
 regulate unregulated point sources of
 storm water under the NPDES permit
 program. Second, to the extent that
 CWA section 402(p)(6) requires
 designation of a "category" of sources,
 the permitting authority may designate
 such (as yet unidentified) sources as a
 category that should be regulated to
 protect water quality.  Though such
 sources may exist and discharge today,
 if neither EPA nor the State/Tribal
 NPDES permitting authority has
 designated the source for regulation
 under CWA section 402(p)(2)(E) to date,
 then CWA section 402(p)(6) provides
 the authority to designate such sources.
  The Agency can designate a  category
 of "not yet identified" sources to be
 regulated, based on local concerns, even
 if data do not exist to support
 nationwide regulation of such sources.
 EPA does not interpret the language in
 CWA section 402(p) to preclude States
 from exercising designation authority
 under these provisions because such
 designation (and subsequent regulation
 of designated sources) is within the
 "scope" of the NPDES program.
  EPA also believes that sources
 regulated pursuant to a State
 designation are part of (and regulated
 under) a federally approved State
 NPDES program, and thus subject to
 enforcement under CWA sections 309
 and 505. Under existing NPDES State
 program regulations, State programs that
 are "greater in scope of coverage" are
 not part of the federally-approved
 program. By contrast, any such State
 regulation of sources in this "reserved
 category" will be within the scope of the
 federal program because today's rule
 recognizes the need for such post
 promulgation designations of
 unregulated point sources of storm
water. Such regulation will be  "more
 stringent" than the federal program
rather than "greater in scope of
coverage" (40 CFR 123.l(h)).
  EPA does not interpret the
congressional direction in CWA section
402(p)(6) to preclude regulation of point
sources of storm water that should be
regulated to protect water quality.
Under CWA section 510, Congress
expressly recognized and preserved the
authority of States to adopt and enforce

-------
68782    Federal Register/Vol. 64, No. 235/Wednesday, December 8, 1999/Rules and Regulations
more stringent regulation of point
sources, as well as any requirement
respecting the control or abatement of
pollution. Section 510 applies, "except
as expressly provided" in the CWA.
CWA section 502(14) does expressly
provide affirmative limitations on the
regulation of certain pollutant sources
through the point source control
program, the NPDES permitting
program. Section 502(14) excludes
agricultural storm water and return
flows from irrigated agriculture from the
definition of point source, and section
402(1) limits applicability of the section
402 permit program for return flows
from irrigated agriculture, as well as for
storm water runoff from certain oil, gas,
and mining operations. Unlike sections
502(14) and 402(1), EPA does not
interpret CWA section 402(p)(6) as an
express provision limiting the authority
to designate point sources of storm
water for regulation on a case-by-case
basis after the promulgation of final
regulations. Any source of storm water
discharge is encouraged to assess its
potential for storm water contamination
and take preventive measures against
contamination. Such proactive actions
could result in the avoidance of future
regulation.
  One  comment was received
requesting clarification of the term
"non-municipal" in § 122.26(a)(9)(ii).
The commenter is concerned that the
term "non-municipal," in this context,
implies that municipally owned or
operated facilities cannot be designated.
The term "non-municipal" in this
context refers to the universe of
unregulated industrial and commercial
facilities that could potentially be
designated according to § 122.26(a)(9)(i)
authority. There  is no exemption for
municipally owned or operated
facilities under these designation
provisions.
  Finally, EPA received comments and
evaluated the proposal under which
operators  of regulated small, medium,
and large MS4s would be responsible
for controlling discharges from
industrial and other facilities into their
systems in lieu of requiring NPDES
permit coverage for such facilities. EPA
did not adopt this framework due to
concerns with administrative and
technical burden on the MS4 operators,
as well as concerns about such an
intergovernmental mandate.
/. Conditional Exclusion for "No
Exposure" of Industrial Activities and
Materials to Storm Water
1. Background
  In  1992, the Ninth Circuit court
remanded to EPA for further
rulemaking, a portion of the definition
of "storm water discharge associated
with industrial activity" that excluded
the category of industrial activity
identified as "light industry" when
industrial materials and/or activities
were not-exposed to storm water. See
NRDCv. EPA, 966 F.2d 1292,1305 (9th
Cir. 1992). Today's final rule responds
to that remand. In the 1990 storm water
regulations, EPA excluded the light
industry category from the requirement
for an NPDES permit if the industrial
materials and/or activities were not
"exposed" to storm water (see
§ 122.26(b)(14)). The Agency had
reasoned that most of the activity at
these types of facilities takes place
indoors and that emissions from stacks,
use of unhoused manufacturing
equipment, outside material storage or
disposal, and generation of large
amounts of dust or particles would be
atypical (55 FR 48008, November 16,
1990).
  The Ninth Circuit determined that the
exemption was arbitrary and capricious
for two reasons. First, the  court found
that EPA had not established a record to
support its assumption that light
industry that was not exposed to storm
water was not "associated with
industrial activity," particularly when
other types of industrial activity not
exposed to storm water remained
"associated with industrial activity."
The court specifically found that "[t]o
exempt these industries from the normal
permitting process  based on an
unsubstantiated assumption about this
group of facilities is arbitrary and
capricious." Second, the court
concluded that the exemption
impermissibly "altered the statutory
scheme" for permitting because the
exemption relied on the unverified
judgment of the light industrial facility
operator to  determine non-applicability
of the permit application requirements.
In other words, the court was critical
that the operator would determine for
itself that there was "no exposure" and
then simply not apply for a permit
without any further action. Without a
basis for ensuring the effective operation
of the permitting scheme—-either that
facilities would self-report actual
exposure or that EPA would be required
to inspect and monitor such facilities—
the court vacated and remanded the rule
to EPA for further rulemaking.
  One of the major concerns expressed
by the FACA Committee, was that EPA
streamline and reinvent certain
troublesome or problematic aspects of
the existing permitting program for
storm water discharges. One area
identified was the mandatory
applicability of the permitting program
to all industrial facilities, even those
"light industrial" activities that are of
very low risk or of no risk to storm
water contamination. Such dischargers
may not have any industrial  sources of
storm water contamination on the plant
site, yet they are still required to apply
for an NPDES storm water permit and
meet all permitting requirements.
Examples of such facilities are a soap
manufacturing plant (SIC Code 28) or
hazardous waste treatment and disposal
facility, where all industrial  activities,
even loading docks, are inside a
building  or under a roof.
  Although they did not provide a
written report, the FACA Committee
members advised EPA that the existing
storm water program should be revised
to allow such facilities to seek an
exclusion from the NPDES storm water
permitting requirements. The
Committee agreed that such an
exclusion should also provide a strong
incentive for other industrial facilities
that conduct industrial activities
outdoors to move the activities under
cover or into buildings to prevent
contamination of rainfall and storm
water runoff. The committee believed
that such a "no exposure" permit
exclusion could be a valuable incentive
for storm water pollution prevention.
  In today's final rule, the Agency
responds to both of the bases for the
court's remand. The exclusion from
permitting based on "no exposure"
applies to all industrial categories listed
in the existing storm water regulations
except construction. The court's opinion
rejected EPA's distinction between light
industry  and other industry,  but it did
not preclude an interpretation that treats
all "non-exposed" industrial facilities in
the same fashion. Presuming that an
industrial facility adequately prevents
exposure of industrial materials and
activities to storm water, today's rule
treats discharges from "non-exposed"
industrial facilities in a manner similar
to the way Congress intended for
discharges from administrative
buildings and parking lots. Specifically,
permits will not be required  for storm
water discharges from these facilities on
a categorical basis.
  To assure that discharges from
industrial facilities really are similar to
discharges from administrative
buildings and parking lots, and to
respond to the second basis for the
court's remand, the permitting
exclusion is "conditional". The person
responsible for a point source discharge
from a "no exposure" industrial source
must meet the conditions of  the
exclusion, and complete, sign and
submit the certification to the
permitting authority for tracking and

-------
            Federal  Register/Vol.  64,  No. 235/Wednesday, December 8, 1999/Rules and  Regulations    68783
 accountability purposes. EPA believes
 today's rule, therefore, is fully
 consistent with the direction provided
 by the court.
   EPA relied upon the "no exposure"
 concept discussed by the FACA
 Committee in developing the "no
 exposure" provisions of today's rule.
 EPA is deleting the sentence regarding
 "no exposure" for the facilities in
 § 122.26(b)(14)(xi) and adding a new
 § 122.26(g) titled "Conditional
 Exclusion for No Exposure of Industrial
 Activities to Storm Water." The "no
 exposure" provision will make storm
 water discharges from all classes of
 industrial facilities eligible for
 exclusion, except storm water
 discharges from regulated construction
 activities. Regulated construction
 activities cannot claim "no exposure"
 because the main pollutants of concern
 (e.g., sediment) generally cannot
 entirely be sheltered from storm water.
   Today's rule represents a significant
 expansion in the scope of the "no
 exposure" provision originally
 promulgated in the 1990 rule, which
 was only for storm water discharges
 from light industry. The intent of
 today's "no exposure" provision is to
 provide a simplified method for
 complying with the CWA to all
 industrial facilities that are entirely
 indoors. This includes facilities that are
 located within a large office building, or
 at \vhich the only items permanently
 exposed to precipitation are roofs,
 parking lots, vegetated areas, and other
 non-industrial areas or activities.
  EPA received several comments
 related to storm water runoff from
 parking lots, rooftops, lawns, and other
 non-industrial areas of an industrial
 facility. Storm water discharges from
 these areas, which may contain
 pollutants or which may result in
 additional storm water flows, are not
 directly regulated under the  existing
 storm water permitting program because
 they are not "storm water discharges
 associated with industrial activity".
 Many comments on this issue supported
 maintaining the exclusion from the
 existing regulations for storm water
 permitting for discharges from
 administrative buildings, parking lots,
 and other non-industrial areas. Other
 comments opposed allowing the
 continued exclusion for discharges from
 non-industrial areas of the site because
 discharges from these areas are
 potentially a significant cause of
 receiving water impairment. These
 comments urged that such discharges
should not be excluded from NPDES
permit coverage. Today's rule does not
require permit coverage for discharges
from a facility's exposed areas that are
 separate from industrial activities such
 as runoff from office buildings and
 accompanying parking lots, lawns and
 other non-industrial areas. This
 approach is consistent with the existing
 storm water rules which were based on
 Congress's intent to exclude non-
 industrial areas such as "parking lots
 and administrative and employee
 buildings." 133 Cong. Rec. 985 (1987).
 EPA also lacks data indicating that
 discharges from these areas at an
 industrial facility cause significant
 receiving water impairments. Therefore,
 the non-industrial areas at a facility do
 not need to be assessed as part of the
 "no exposure" certification.
   EPA received comments related to
 industrial facilities that achieve "no
 exposure" by constructing large
 amounts of impervious surfaces, such as
 roofs, where previously there were
 pervious or porous surfaces into which
 storm water could infiltrate. Some
 commenters made the point that large
 amounts of impervious area may cause
 a significant increase in storm water
 volume flowing off the industrial
 facility, and thus  may cause adverse
 receiving water impacts simply due to
 the increased quantity of storm water
 flow. Some commenters said that storm
 water discharges from impervious areas
 at an industrial facility are generally
 more frequent, and often larger, than
 discharges from the pre-existing natural
 surfaces. They believe that these
 discharges will contain pollutants
 typical of commercial areas and roads
 and are an equal threat to direct human
 uses of the water and can cause equal
 damage to aquatic life and its  habitat.
 Other commenters believe that if
 Congress or EPA addresses the issue of
 flow, it should be addressed on a
 broader scale than merely through the
 "no exposure" exclusion, and that EPA
 has no authority under any existing
 legal framework to regulate flow
 directly. Some commenters stated that
 developing federal parameters for the
 control of water quantity, i.e. flow,
 would result in federal intrusion into
 land use planning, an authority that
 they claim is solely within the purview
 of State governments and their political
 subdivisions.
  EPA is not attempting to regulate flow
 via the "no exposure" provisions. EPA
 does agree, however,  that increases in
 impervious surfaces can result in
 increased runoff volumes from the site
 which in turn may increase pollutant
 loading. In addition, the Agency notes
that in some States water quality
 standards include water quality criteria
for flow or turbidity. Therefore, in order
to provide a minimal amount of
information on possible impacts from
 increased pollutant loading and runoff
 volume, EPA's "no exposure"
 certification form (see Appendix 4) asks
 the discharger to indicate if they have
 paved or roofed over a formerly
 exposed, pervious area in order to
 qualify for the "no exposure" exclusion.
 If the answer is yes, the discharger must
 indicate, by choosing from three
 possible responses, approximately how
 much impervious area was created to
 achieve "no exposure". The choices are:
 (1) less than 1 acre, (2) 1 to 5 acres, and
 (3) more than  5 acres. This requirement
 provides additional information that
 will aid in determining if discharges
 from the facility are causing adverse
 receiving water impacts. EPA intends to
 prevent water quality impacts resulting
 from increased discharges of pollutants,
 which may result from increased
 volume of runoff. In many cases,
 consideration  of the increased flow rate,
 velocity and energy of storm water
 discharges, following  construction of
 large amounts of impervious surfaces,
 must be taken into consideration in
 order to reduce the discharge of
 pollutants, to meet water quality
 standards and to prevent degradation of
 receiving streams. EPA recommends
 that dischargers consider these factors
 when making modifications to their site
 in order to qualify for  the "no exposure"
 exclusion.

 2. Today's Rule
  In order to claim relief under  the "no
 exposure" provision, the discharger of
 an otherwise regulated facility must
 submit a no exposure  certification that
 incorporates the questions of
 § 122.26(g)(4)(iii) to the NPDES
 permitting authority once every 5 years.
 This provision applies across all
 categories of industrial activity covered
 by the existing program, except
 discharges  from construction activities.
  In addition to submitting a "no
 exposure" certification every 5 years,
 the facility must allow the NPDES
 permitting authority or operator of an
 MS4 (where there is a  storm water
 discharge to the MS4)  to inspect the
 facility and to make such inspection
 reports publicly available upon request.
Also, upon request, the facility must
submit a copy  of the "no exposure"
 certification to the operator of the MS4
 into which the facility discharges (if
applicable). All "no exposure"
certifications must be signed in
accordance with the signatory
requirements of § 122.22. The "no
exposure" certification is non-
transferable. In the event that the facility
operator changes, the new discharger
must submit a  new "no exposure"
certification.

-------
68784    Federal Register/Vol.  64,  No. 235/Wednesday,  December  8,  1999/Rules  and Regulations
  Members of the FACA Committee
urged that EPA not allow dischargers
certifying "no exposure" to take actions
to qualify for this provision that result
in a net environmental detriment. In
developing a regulatory implementation
mechanism, however, EPA found that
the phrase "no net environmental
detriment," was too imprecise to use
within this context. Therefore, today's
rule addresses this issue by requiring
information that should help the
permitting authority to determine
whether actions taken to qualify for the
exclusion interfere with the attainment
or maintenance of water quality
standards, including designated uses.
Permitting authorities will be able,
where necessary, to make a
determination by evaluating the
activities that changed at the industrial
site to achieve "no exposure", and
assess whether these changes cause an
adverse impact on, or have the
reasonable potential to cause an
instream excursion of, water quality
standards, including designated uses.
EPA anticipates that many efforts to
achieve "no exposure" will employ
simple good housekeeping and
contaminant  cleanup activities. Other
efforts may involve moving materials
and industrial activities indoors into
existing buildings or structures.
  In very limited cases, industrial
operators may make major changes at a
site to achieve "no exposure". These
efforts may include constructing a new
building or cover to eliminate exposure
or constructing structures  to prevent
run-on and storm water contact with
industrial materials or activities. Where
major changes to achieve "no exposure"
increase the impervious area of the site,
the facility operator must provide this
information on the "no exposure"
certification form as discussed above.
Using this and other available data and
information,  permitting authorities
should be able to assess whether any
major change has resulted in increased
pollutant concentrations or loadings,
toxicity of the storm water runoff, or a
change in natural hydrological patterns
that would interfere with the attainment
and maintenance of water quality
standards, including designated uses or
appropriate narrative, chemical,
biological, or habitat criteria where such
State or Tribal water quality standards
exist. In these instances, the facility
operator and their NPDES permitting
authority should take appropriate
actions to ensure that attainment or
maintenance of water quality standards
can be achieved. The NPDES permitting
authority should decide if the facility
must obtain coverage under an
individual or general permit to ensure
that appropriate actions are taken to
address adverse water quality impacts.
  While the intent of today's "no
exposure" provision is to reduce the
regulatory burdens on industrial
facilities and government agencies, the
FACA Committee suggested that the
NPDES permitting authority consider a
compliance assessment program to
ensure that facilities that have availed
themselves of this "no exposure" option
meet the applicable requirements.
Inspections could be conducted at the
discretion of the NPDES authority and
be coordinated with other facility
inspections. EPA expects, however, that
the permitting authority will conduct
inspections when it becomes aware of
potential water quality impacts possibly
caused by the facility's storm water
discharges or when  requested to do so
by adversely affected members of the
public. The intent of this provision is
that the 5 year "no exposure"
certification be fully available to, and
enforceable by, appropriate federal and
State authorities under the CWA.
Private citizens can  enforce against
facilities for discharges of storm water
that are inconsistent with a "no
exposure" certification if storm water
discharges from such facilities are not
otherwise permitted and in compliance
with applicable requirements.
  EPA received comments from owners,
operators and representatives of Phase I
facilities classified as "light industry" as
defined by the regulations at
§ 122.26(b)(14)(xi). The comments
recommended maintaining  the approach
of the existing regulations which does
not require the discharger to submit any
supporting documentation to the
permitting authority in order to claim
the "no exposure" exclusion from
permitting. As discussed previously, the
"no exposure" concept was developed
in response to the Ninth Circuit court's
remand of part of the existing rules back
to EPA. The court found that EPA
cannot rely on the "unverified
judgment" of the facility.  The comments
opposing documentation  did not
address the "unverified judgment"
concern.
  Today's rule is a "conditional"
exclusion from permitting which
requires all categories, including the
"light industrial" facilities that have no
exposure of materials to storm water, to
submit a certification to the permitting
authority. Upon receipt of a complete
certification, the permitting authority
can review the information, or call, or
inspect the facility if there are doubts
about the facility's "no exposure" claim.
Also, if the facility discharges into an
MS4, the operator of the MS4 can
request a copy of the certification, and
can inspect the facility. The public can
request a copy of the certification and/
or inspection reports. In adopting these
conditional "no exposure" provisions,
the Agency addressed the Ninth Circuit
court's ruling regarding the discharger's
unverified judgment.
  EPA received one comment
requesting clarification on whether the
anti-backsliding provisions in the
regulations at § 122.44(1] apply to
industrial facilities that are currently
covered under an NPDES storm water
permit, and whether such facilities
could qualify for the "no exposure"
exclusion under today's rule. The anti-
backsliding provisions will not prevent
most industrial facilities that can certify
"no exposure" under today's rule from
qualifying for an exclusion from
permitting. The anti-backsliding
provisions contain 5 exceptions that
allow permits to be renewed, reissued or
modified with less stringent  conditions.
One exception at § 122.44(1)(2)(A)
allows less stringent conditions if
"material and substantial alterations or
additions to the permitted facility
occurred after permit issuance which
justify the application of a less stringent
effluent limitation." Section
122.44(1)(B3(1) also allows less stringent
requirements if "information is
available which was not available at the
time of permit issuance and which
would have justified the application of •
less stringent effluent limitations at the
time of permit issuance." Facility's
operators who certify "no exposure"
and submit the required information
once every 5 years will have  provided
the permitting authority "information
that was not available at the time of
permit issuance." Also, some facilities
may, in order to achieve "no exposure",
make "material and substantial
alterations or additions to the permitted
facility." Therefore, most facilities
covered under existing NPDES general
permits for storm water (e.g., EPA's
Multi-Sector General Permit) will be
eligible for the conditional "no
exposure" exclusion from permitting
without concern about the anti-
backsliding provisions. Such
dischargers will have met one or both of
the anti-backsliding exceptions detailed
above. Facilities that are covered under
individual permits containing numeric
limitations for storm water should
consult with their permitting authority
to determine whether the anti-
backsliding provisions will prevent
them from qualifying for the exclusion
from permitting (for that discharge
point) based on a certification of "no
exposure".

-------
           Federal Register/Vol. 64, No.  235/Wednesday,  December  8, 1999/Rules and Regulations    68785
   EPA received several comments
 regarding the timing of when the "no
 exposure" certification should be
 submitted. The proposed rule said that .
 the "no exposure" certification notice
 must be submitted "at the beginning of
 each permit term or prior to
 commencing discharges during a permit
 term." Some commenters interpreted
 this statement to mean that existing
 facilities can only submit the
 certification at the time a permit is being
 issued or renewed. EPA intended the
 phrase "at the beginning of each permit
 term" to mean  "once every 5 years" and
 today's rule reflects this clarification.
 EPA envisions that the NPDES storm
 water program will be  implemented
 primarily through general permits
 which are issued for a  5 year term.
 Likewise the "no exposure" certification
 term is 5 years. The NPDES permitting
 authority will maintain a simple
 registration list that should impose only
 a minor administrative burden on the
 permitting authority. The registration
 list will allow for tracking of industrial
 facilities claiming the exclusion. This
 change allows a facility to submit a "no
 exposure" certification at any time
 during the term of the permit, provided
 that a new certification is submitted
 every 5 years from the time it is first
 submitted (assuming that the facility
 maintains a "no exposure" status). Once
 a discharger has established that the
 facility meets the definition of "no
 exposure", and submits the necessary
 "no exposure" certification, the
 discharger must maintain their "no
 exposure" status. Failure to maintain
 "no exposure" at their  facility could
 result in the unauthorized discharge of
 pollutants to waters of  the United States
 and enforcement for violation of the
 CWA. Where a discharger believes that
 exposure could occur in the future due
 to some anticipated change at the
 facility, the discharger should submit an
 application and obtain  coverage under
 an NPDES permit prior to such
 discharge to avoid penalties.
  Where EPA is the permitting
 authority, dischargers may submit a "no
 exposure" certification at any time after
 the effective date of today's rule. Where
EPA is not the permitting authority,
 dischargers may not be able to submit
 the certification until the non-federal
permitting authority completes any
necessary statutory or regulatory
changes to adopt this "no exposure"
provision. EPA recommends that the
discharger contact the permitting
authority for guidance on when the "no
exposure" certification should be
submitted.
  EPA received comments on the
proposed rule requirement that the
 discharger "must comply immediately
 with all the requirements of the storm
 water program including applying for
 and obtaining coverage under an NPDES
 permit," if changes occur at the facility
 which cause exposure of industrial
 activities or materials to storm water.
 The comments expressed the difficultly
 of immediate compliance. EPA expects
 that most facility changes can be
 anticipated, therefore dischargers
 should apply for and obtain NPDES
 permit coverage in advance of changes
 that result in exposure to industrial
 activities or materials. Permitting
 authorities may grant additional time,
 on a case-by-case basis, for preparation
 and implementation of a storm water
 pollution prevention plan.
   Finally, today's rule at § 122.26(g)(4)
 includes the information which must be
 included on the  "no exposure"
 certification. Authorized States, Tribes
 or U.S. Territories may develop their
 own form which includes this required
 information, at a minimum. EPA
 adopted the requirements (with
 modification) from the draft "No
 Exposure Certification Form" published
 as an appendix to the proposed rule.
 Modifications were made to the draft
 form to address comments received and
 to streamline the required information.
 EPA included these certification
 requirements in today's rule in order to
 preserve its integrity. Dischargers in
 areas where EPA is the permitting
 authority should use the "No Exposure
 Certification" form included in
 Appendix 4.

 3. Definition of "No Exposure"
  For purposes of this section, "no
 exposure" means that all industrial
 materials or activities  are protected by a
 storm resistant shelter to prevent
 exposure to rain, snow, snowmelt, and/
 or runoff. Industrial materials or
 activities include, but are not limited to,
 material handling equipment or
 activities, industrial machinery, raw
 materials, intermediate products, by-
 products, final products, or waste
 products. Material handling activities
 include the storage, loading  and
 unloading, transportation, or
 conveyance of any raw material,
 intermediate product,  final product or
 waste product. However, storm resistant
 shelter is not required for: (1) Drums,
 barrels, tanks, and similar containers
 that are tightly sealed, provided those
 containers are not deteriorated and do
 not leak; (2) adequately maintained
 vehicles used in material handling; and
 (3) final products, other than products
 that would be mobilized in storm water
 discharge (e.g., rock salt). Each of these
three exceptions  to the no exposure
 definition are discussed in more detail
 below.
   EPA intends the term "storm resistant
 shelter" to include completely roofed
 and walled buildings or structures, as
 well as structures with only a top cover
 but no side coverings, provided material
 under the structure is not otherwise
 subject to any run-on and subsequent
 runoff of storm water. While the Agency
 intends that this provision promote
 permanent "no exposure", EPA
 understands that certain vehicles could
 pass between buildings and, during
 passage, be exposed to  rain and snow.
 Adequately maintained vehicles such as
 trucks, automobiles, forklifts, or other
 such general purpose vehicles at the
 industrial site that are not industrial
 machinery, and that are not leaking
 contaminants or are not otherwise a
 source of industrial pollutants, could be
 exposed to precipitation or runoff. Such
 activities alone does not prevent a
 discharger from being able to certify no
 exposure under this provision.
 Similarly, trucks or other vehicles
 awaiting maintenance at vehicle
 maintenance facilities,  as defined at
 § 122.26(b)(14)(viii), that are not leaking
 contaminants or  are not otherwise a
 source of industrial pollutants, are not
 considered exposed.
  In addition, EPA recognizes that there
 are circumstances where permanent "no
 exposure" of industrial activities or
 materials is not possible. Under such
 conditions, materials and activities may
 be sheltered with temporary covers,
 such as tarps, between periods of
 permanent enclosure. The final rule
 does not specify every such situation.
 EPA intends that permitting authorities
 will address this issue on a case-by-case
 basis. Permitting authorities can
 determine the circumstances under
 which temporary structures will or will
 not meet the requirements of this
 section. Until permitting authorities   -
 specifically determine otherwise, EPA
 recommends application of the "no
 exposure" exclusion for temporary
 sheltering of industrial  materials or
 activities only during facility renovation
 or construction, provided that the
 temporary shelter achieves the intent  of
 this section. Moreover,  "exposure" that
results from a leak in protective
 covering would only be considered
 "exposure" if not corrected prior to the
 next storm water discharge event. EPA
received one comment requesting that
this allowance for temporary shelter be
 limited to facility renovation or
construction directly related to the
 industrial activity requiring temporary
shelter, and be scheduled to minimize
the use of temporary shelter. Another
comment suggested placing time limits

-------
68786    Federal  Register/Vol.  64,  No. 235/Wednesday, December 8, 1999/Rules and Regulations
on the use of temporary shelter. The
commenter did not recommend a
specific time period, rather the
comment said that renovation in some .
instances may take years, and that EPA
should not allow temporary shelter over
prolonged periods. EPA agrees that the
use of temporary shelter must be related
to the renovation or construction at the
site, and be scheduled or designed to
minimize the use of temporary shelter.
Further, EPA agrees that the use of
temporary shelter should be limited in
duration, but does not intend to define
"temporary" or "prolonged period".
  Many final products are intended for
outdoor use and pose little risk of storrn
water contamination, such as new cars.
Therefore, final products, except those
.that can be mobilized in storm water
discharge, can be "exposed" and still
allow the discharge to certify "no
exposure". EPA intends the term "final
products" to mean those products that
are not used in producing another
product. Any product that can be used
to make another product is considered
an "intermediate product." For
example, a facility that makes horse
trailers can store the finished trailers
outdoors as a final product. The storage
of those final products does not prevent
eligibility to claim "no exposure".
However, any facility that makes parts
for the horse trailers (e.g., metal tubing,
sheet metal, paint) is not eligible for the
"no exposure" exclusion from
permitting if those "intermediate
products" are stored outdoors (i.e.,
"exposed").
  EPA received comments related to
materials in  drums, barrels, tanks and
similar containers.  Some comments
objected to the language in the preamble
to the proposed rule that would have
recommended that the "exposure"
determination for drums and barrels be
based on the "potential to leak." Those
comments said that all drums and
barrels have the potential to leak,
thereby making certification impossible.
They recommended allowing outdoor
storage of drums and barrels except for
those that "are leaking" at the time of
certification, Other comments suggested
allowing drums and barrels to be stored
outside only if the drums and barrels:
are empty; have secondary containment;
or there is a spill contingency plan in
place. Opposing comments suggested
that allowing outdoor exposure of
drums and barrels, based on existing
integrity and condition, is inconsistent
with the "however packaged" proposed
rule language, and also would not
satisfy the Ninth Circuit remand. The
comments point out that the former rule
was invalidated by the court in part
because it relied on the "unverified
judgment" of the light industrial facility
operator to determine the non-
applicability of the permit requirements,
and that allowing the facility operator to
determine the condition of their drums
and barrels would result in the same
flaw.
  In response, EPA believes that drums
and barrels that are stored outdoors pose
little risk of storm water contamination
unless they are open, deteriorated or
leaking. The Agency has modified
today's rule accordingly. EPA intends
the term "open" to mean any container
that is not tightly sealed and "sealed" to
mean banded or otherwise secured and
without operational taps or valves.
Drums, barrels, tanks, and similar
containers may only be stored outdoors
under this conditional exclusion. The
addition of material to or withdrawing
of material from these containers while
outside is deemed "exposure". Moving
the containers while outside does not
create "exposure" provided that the
containers are not open, deteriorated or
leaking. In order to complete the "no
exposure" certification, a facility
operator must inspect all drums, barrels,
tanks  or other containers stored outside
to ensure that they are not open,
deteriorated, or leaking. EPA
recommends that the discharger
designate someone at the facility to
conduct frequent inspections to verify
that the drums, barrels, tanks or other
containers remain in a condition such
that they are not open, deteriorated or
leaking. Drums, barrels, tanks or other
containers stored outside that have
valves which are used to put material in
or take material out of the container,
and that have dripped or may drip, are
considered to be "leaking" and must be
under a storm resistant shelter in order
to qualify for the no exposure exclusion.
Likewise, leaking pipes containing
contaminants exposed to storm water
are  deemed "exposed." If at any time
drums, barrels, tanks or similar
containers are opened, deteriorated or
leaking, the discharger should take
immediate actions to close or replace
the  container. Any resulting
unpermitted discharge would violate
the  CWA. The Director, the operator of
the  MS4, or the municipality may
inspect the facility to verify that all of
the  applicable areas meet the "no
exposure" conditions as specified in the
rule language. In requiring submission
of the conditional "no exposure"
certification and allowing the permitting
authority and the operator of the MS4 to
inspect the facility, today's rule does not
rely on the unverified judgment of the
facility to determine that the no
exposure provision is being met.
  EPA received several comments
related to trash dumpsters that are
located outside. The preamble to the
proposed rule listed dumpsters in the
same grouping as drums and barrels,
which based exposure on the "potential
to leak". Today's rule distinguishes
between dumpsters and drums/barrels.
In the Phase I Question and Answer
document (volume 1, question 52) the
Agency noted that a covered dumpster
containing waste material that is kept
outside is not considered "exposed" as
long as "the container is completely
covered and nothing can drain out holes
in the bottom, or is lost in loading onto
a garbage truck." EPA affirms this
approach today. Industrial refuse and
industrial trash that is left uncovered is
deemed "exposed."
  For purposes of this provision,
particulate matter emissions from roof
stacks/vents that are regulated and in
compliance under other environmental
protection programs, such as air quality
control programs, and that do not cause
storm water contamination, are
considered "not exposed." EPA
received comments  on the phrase in the
draft "no exposure" certification form
that asked whether "particulate
emissions from roof stacks/vents not
otherwise regulated, and in quantities
detectable in the storm water outflow,"
are  exposed to precipitation. One
comment expressed concern that the
phrase "in quantities detectable in the
storm water outflow" implies that the
facility must conduct monitoring prior
to completing the checklist, and must
continue to monitor after receiving the
no exposure exclusion, in order to be
able to verify compliance with the no
exposure provision. Another comment
said that current measurement
technology allows detection of
pollutants at levels that may not cause
environmental harm. EPA does not
intend to require monitoring of runoff
from facilities with roof stacks/vents
prior to or after completing and
submitting the no exposure certification.
EPA has  thus replaced the phrase "in
quantities detectable" with "evident" to
convey the message that emissions from
some roof stacks/vents have the
potential to contaminate storm water
discharges in quantities that are
considered significant or that cause or
contribute to a water quality standards
violation. In those instances where the
permitting authority determines that
particulate emissions from facility roof
stacks/vents are a significant contributor
of pollutants or contributing to water
quality violations, the permitting
authority may  require the discharger to
apply for and obtain coverage under a

-------
           Federal Register/Vol.  64,  No. 235/Wednesday, December 8, 1999/Rules and  Regulations    68787
permit. Visible deposits of residuals
(e.g., particulate matter) near roof or
side vents are considered "exposed".
Likewise, visible "track out" (i.e.,
pollutants carried on the tires of
vehicles) or windblown raw materials
are deemed "exposed."
  EPA received a comment requesting
an allowance under the "no exposure"
provision for industrial facilities with
several outfalls at a site where some, but
not all of the outfalls drain non-exposed
areas. The commenter provided an
example of an industrial facility that has
5 outfalls draining different areas of the
site, where two of those outfalls drain
areas where industrial activities or
materials are not exposed to storm
water. The comment requested that the
facility in this example be allowed to
submit a "no exposure" certification in
order to be relieved of permitting
obligations for discharges from those
two outfalls.
  EPA agrees, but the comment would
be implemented on an outfall-by-outfall
basis in the permitting process, not
through the "no exposure"  exclusion.
The "no exposure" provision was
developed to allow exclusion from
permitting of discharges from entire
industrial facilities (except
construction), based on a claim of "no
exposure" for all areas of the facility
where industrial materials or activities
occur. Where exposure to industrial
materials or activities exist at some but
not all areas of the  facility, the "no
exposure" exclusion from permitting is
not allowed because permit coverage  is
still required for storm water discharges
from the exposed areas. Relief from
permit requirements for outfalls
draining non-exposed areas should be
addressed through the permit process.
in coordination with the permitting
authority. Most NPDES general permits
for storm water discharge provide
enough flexibility to allow minimal or
no requirements for non-exposed areas
at industrial facilities. If the permitting
authority determines that additional
flexibility is needed for this scenario,
the permits could be modified as
necessary.
K. Public Involvement/Public Role
  The Phase IIFACA Subcommittee
discussed the appropriate role of the
public in successful implementation of
a municipal storm  water program. EPA
believes that an educated and actively
involved public is  essential to a
successful municipal storm water
program. An educated public increases
program compliance from residents and
businesses as they  realize their
individual and collective responsibility
for protecting water resources (e.g., the
residents and businesses could be
subject to a local ordinance that
prohibits dumping used oil down storm
sewers). Finally, the program is also
more likely to receive public support
and participation when the public is
actively involved from the program's
inception and allowed to participate in
the decision making process.
  In a time of limited staff and financial
resources, public volunteers offer
diverse backgrounds and expertise that
may be used to plan,  develop, and
implement a program that is tailored to
local needs (e.g., participate in public
meetings and other opportunities for
input, perform lawful volunteer
monitoring, assist in program
coordination with other preexisting and
related programs, aid in the
development and distribution of
educational materials, and provide
public training activities). The public's
participation is also useful in the areas
of information dissemination/education
and reporting of violators, where large
numbers of community members can be
more effective than a few regulators.
  The public can also petition the
NPDES permitting authority to require
an NPDES permit for a discharge
composed entirely of storm water that
contributes to a violation of a water
quality standard or is a significant
contributor of pollutants to waters of the
United States. In evaluating such a
petition, the NPDES permitting
authority is encouraged to consider the
set of designation criteria  developed for
the evaluation of small MS4s located
outside of an urbanized area in places
with a population of at least 10,000 and
a population density  of 1,000 or more.
Furthermore, any person can protect
water bodies by taking civil action
under section 505 of the CWA against
any person who is alleged to be in
violation of an effluent standard or
permit condition. If civil action is taken,
EPA encourages citizen plaintiffs to
resolve any disagreements or concerns
directly with the parties involved, either
informally or through any available
alternative dispute resolution process.
  EPA recognizes that public
involvement and participation pose
challenges. It requires a substantial
initial investment of staff and financial
resources, which could be very limited.
Even with this investment, the public
might not be interested in participating.
In addition, public participation could
slow down the decision making process.
However, the benefits are numerous.
  EPA encourages members of the
public to contact the NPDES permitting
authority or local MS4s operator for
information on the municipal  storm
water program and ways to participate.
Such information may also be available
from local environmental, nonprofit and
industry groups.
  Some commenters stressed the need
to suggest to the public that they have
a responsibility to fund the municipal
storm water program. While EPA
believes it is important that the program
be adequately funded, today's rule does
not address appropriate mechanisms or
levels for such funding.
  EPA received comments expressing
concern that considerable public
involvement requirements could result
in increased litigation. EPA is not
convinced there is a correlation between
meaningful public education programs
and any increased probability of
litigation.
  Finally, EPA received comments
stating that the Agency should not en
courage volunteer monitoring unless
proper procedures are followed. EPA
agrees. EPA encourages only lawful
monitoring, i.e., obtaining the necessary
approval if there is any question about
lawful access to sites. Moreover, as a
matter of good practice and to enhance
the  validity and usefulness of the
results, any party, public or private,
conducting water quality monitoring is
encouraged to use appropriate quality
control procedures and approved
sampling and analytic methods.

L. Water Quality Issues

1. Water Quality Based Effluent  Limits
  In addition to technology based
requirements, all point source
discharges of industrial storm water are
subject to more stringent NPDES
permitting requirements when
necessary to meet water quality
standards. CWA sections 402(p)(3)(A)
and 301(b)(l)(C). For municipal  separate
storm sewers, EPA or the State may
determine that other permit provisions
(e.g. one of the minimum measures) are
appropriate to protect water quality and,
for discharges to impaired waters, to
achieve reasonable further progress
toward attainment of water quality
standards pending implementation of a
TMDL. CWA section 402(p)(3)(B)(iii).
See Defenders of Wildlife, et al.
Browner, No. 98-71080 (9th cir., August
11,1999). Discharges of storm water
also must comply with applicable
antidegradation policies and
implementation methods to maintain
and protect water quality. 40 CFR
131.12. Section 122.34(a)  emphasizes
this point by specifically noting that a
storm water management program.
designed to reduce the discharge of
pollutants from the storm sewer system
"to  the maximum extent practicable" is
also designed to protect water quality.

-------
 68788    Federal Register/Vol. 64, No.  235/Wednesday,  December  8,  1999/Rules  and Regulations
 Permits issued to non-municipal
 sources of storm water must include
 water quality-based effluent limits
 where necessary to meet water quality
 standards.
   Commenters challenged EPA's
 interpretation of the CWA as requiring
 water quality-based effluent limits for
 MS4s when necessary to protect water
 quality. Commenters asserted that CWA
 402(p)(3)(B), which addresses permit
 requirements for municipal discharges,
 limits the scope of municipal program
 requirements to an effective prohibition
 on non-storm water discharges to a
 separate storm sewer and to controls
 which reduce pollutants to the
 "maximum extent practicable, including
 management practices, control
 techniques and system design and
 engineering methods." They asserted
 that the final rule should clarify that
 neither numeric nor narrative water
 quality-based limits are appropriate or
 authorized for MS4s.
   EPA disagrees that section 402(p)(3)
 divests permitting authorities of the
 tools necessary to issue permits to meet
 water quality standards. Section
 402(p)(3)(B)(iii) specifically preserves
 the authority for EPA or the State  to
 include other provisions determined
 appropriate to reduce pollutants in
 order to protect water quality. Defenders
 of Wildlife, slip op. at 11688. Small
 MS4s regulated under today's rule are
 designated under CWA 402(p)(6) "to
 protect water quality."
   Commenters  argued that water quality
 standards, particularly numeric criteria,
 were not designed to address storm
 water discharges. The episodic nature
 and magnitude of storm water events,
 they argue, make it impossible to apply
 the "end of pipe" compliance
 assessment approach,  for example, in
 the development of water quality based
 effluent limits.
  EPA's disagrees with the Commenters
 arguments about the inability of water
 quality criteria to address high flow
 conditions. Today's final rule does,
 however, address the concern that
 numeric effluent limits will necessitate
 end of pipe treatment and  the need to
 provide a workable alternative.
  Today's rule was developed under the
 approach outlined in the Interim
 Permitting Policy for Water Quality-
 Based Effluent Limitations in Storm
 Water Permits, issued  on August 1,
 1996. 61 FR 43761 (November 26,1996)
 (the "Interim Permitting Policy").  EPA
 intends to issue NPDES permits
 consistent with the Interim Permitting
Policy, which provides as follows:
  In response to recent questions
regarding the type of water quality-
based effluent limitations that are  most
 appropriate for NPDES storm water
 permits, EPA is adopting an interim
 permitting approach for regulating wet
 weather storm water discharges. Due to
 the nature of storm water discharges,
 and the typical lack of information on
 which to base numeric water quality-
 based effluent limitations (expressed as
 concentration and mass), EPA will use
 an interim permitting approach for
 NPDES storm water permits.
   "The interim permitting approach
 uses best management practices (BMPs)
 in first-round storm water permits, and
 expanded or better-tailored BMPs in
 subsequent permits, where necessary, to
 provide for the  attainment of water
 quality standards. In cases where
 adequate information exists to develop
 more specific conditions or limitations
 to meet water quality standards, these
 conditions or limitations are to be
 incorporated into storm water permits,
 as necessary and appropriate. This
 interim permitting approach is not
 intended to affect those storm water
 permits that already include
 appropriately derived numeric water
 quality-based effluent limitations. Since
 the interim permitting approach only
 addresses water quality-based effluent
 limitations, it also does not affect
 technology-based effluent limitations,
 such as those based on effluent
 limitations guidelines or developed
 using best professional judgment, that
 are incorporated into storm water
 permits.
   "Each storm water permit should
 include a coordinated and cost-effective
 monitoring program to gather necessary
 information to determine the extent to
 which the permit provides for
 attainment of applicable water quality
 standards and to determine the
 appropriate conditions or limitations of
 subsequent permits. Such a monitoring
 program may include ambient
 monitoring, receiving water assessment,
 discharge monitoring (as needed), or a
 combination of monitoring procedures
 designed to gather necessary
 information.
  "This interim permitting approach
 applies only to EPA; however, EPA also
 encourages authorized States and Tribes
to adopt similar policies for storm water
permits. This interim permitting
 approach provides time, where
necessary, to more fully assess the range
of issues and possible options for the
 control of storm water discharges for the
protection of water quality. This interim
permitting approach may be modified as
a result of the ongoing Urban Wet
Weather Flows Federal Advisory
Committee policy dialogue on this
subject."
   One commenter challenged the
 Interim Permitting Policy on a
 procedural basis, arguing that it was
 published without opportunity for
 public notice and comment. In
 response, EPA notes that the Policy was
 included verbatim and made available
 for public comment in the proposal to
 today's final rule. Prior to that proposal,
 the Agency defended the application of
 the Policy on a case-by-case basis in
 individual permit proceedings.
 Moreover, the essential elements of the
 Policy—that narrative effluent
 limitations are the most appropriate
 form of effluent limitations for storm
 water dischargers from municipal
 sources—was inherent in § 122.34(a) of
 the proposed rule, and was the subject
 of extensive public comment. In any
 event, the Policy  does not constitute a
 binding obligation. It is policy, not
 regulation.
  Consistent with the recognition of
 data needs underlying the Policy, EPA
 will evaluate the small MS4 storm water
 regulations after the second round of
 permit issuance. Section 122.34(e)(2) of
 today's rule expressly provides that for
 the interim ten-year period, "EPA
 strongly recommends that until  the
 evaluation of the storm water program
 in § 122.37, no additional requirements
 beyond the minimum control measures
 be imposed on regulated small MS4s
 without the agreement of the operator of
 the affected small MS4, except where an
 approved TMDL or equivalent analysis
 provides adequate information to
 develop more specific measures to
 protect water quality." This approach
 addresses the concern for protecting
 water resources from the threat posed by
 storm water discharges with the
 important qualification that there must
 be adequate information on the
 watershed or a specific site  as a basis for
 requiring tailored storm water controls
 beyond the minimum control measures.
 As indicated, the Interim Permitting
 Policy has several important
 limitations—it does not apply to
 technology-based controls or to sources
 that already have numeric end of pipe
 effluent limitations. EPA encourages
 authorized States and Tribes to adopt
 policies similar to the Interim
 Permitting Policy when developing
 storm water discharge programs. For a
 discussion of appropriate monitoring
 activities, see Section H.S.d., Evaluation
 and Assessment.
  Where a water quality analysis
 indicates there is a need and basis for
 deriving water quality-based effluent
 limits in NPDES permits for storm water
 discharges regulated under today's rule,
EPA believes that most of these cases
 would be satisfied by narrative effluent

-------
           Federal Register/Vol. 64, No.  235/Wednesday,  December  8, 1999/Rules and Regulations    68789
 limitations that require the
 implementation of BMPs. NPDES permit
 limits will in most cases continue to be
 based on the specific approach outlined •
 in today's rule for the implementation of
 BMPs as the most appropriate form of
 effluent limitation to satisfy technology
 and water quality-based requirements.
 See § 122.34(a). For storm water
 management plans with existing BMPs,
 this may require further tailoring of
 BMPs to address the pollutant(s) of
 concern, the nature of the discharge and
 the receiving water. If the permitting
 authority determines that, through
 implementation of appropriate BMPs
 required by the NPDES storm water
 permit, the discharge has the necessary
 controls to provide for attainment of
 water quality standards, additional
 controls are not needed in the  permit.
 Conversely, if a discharger (MS4,
 industrial or construction) fails to adopt
 and implement adequate BMPs, the
 permittee and/or the permitting
 authority should consider a different
 mix of BMPs or more specific
 conditions to ensure water quality
 protection.
  Some commenters observed that there
 was no evidence from the experience of
 storm water dischargers regulated under
 the existing NPDES storm water
 program, or from studies or reports that
 allegedly support EPA's position, that
 implementation of BMPs to satisfy the
 six minimum control measures would
 meet applicable water quality standards
 for a regulated small MS4. In response,
 EPA acknowledges that the six
 minimum measures are intended to
 implement the statutory requirement to
 control discharges to the maximum
 extent practicable, and they may not
 result in the attainment of water quality
 standards in all cases. The control
 measures do, however, focus on and
 address well-documented threats to
 water quality associated with storm
 water discharges. Based on the
 collective expertise of the FACA Sub-
 committee, EPA believes that
 implementation of the six minimum
 measures will, for most regulated small
 MS4s, be adequate to protect water
 quality, and for other regulated small
 MS4s will substantially reduce the
 adverse impacts of their discharges on
 water quality.
  Some commenters asserted that
 analyses of existing water quality
 criteria suggest that numeric criteria for
 aquatic life may be overprotective if
 applied to storm water discharges.
 These comments maintained that an
 approach that prohibits exceedance of
 applicable water quality criteria is
 unworkable. Various commenters
recommended wet weather specific
criteria, variances to the criteria during
wet weather events, and seasonal
designated uses. Other commenters
noted that water quality-based effluent
limits in NPDES permits have
traditionally been developed based on
dry weather flow conditions (e.g.,
assuming critical low-flow conditions in
the receiving water to ensure protection
of aquatic life and human health). Wet
weather discharges, however, typically
occur under high-flow conditions in the
receiving water. Assumptions regarding
mass balance equations and size of
mixing zones may also not be pertinent
during wet weather.
  EPA acknowledges the need to devise
a regulatory program that is both
flexible enough to accommodate the
episodic nature, variability and volume
of wet weather discharges and
prescriptive enough to ensure protection
of the water resource. EPA believes that
wet weather discharges can be
adequately addressed in the existing
regulations through refining designated
uses and assigning criteria that are
tailored to the level of water quality
protection described by the refined
designated use.
  EPA believes that lack of precision in
assigning designated uses and
corresponding criteria by States and
Tribes, in many cases may result in
application of water quality criteria that
may not appropriately match the
intended condition of the water body.
States and Tribes have frequently
designated uses without regard to site-
specific wet weather conditions.
Because certain uses (swimming, for
example) might not exist during high-
intensity storm events or in the winter,
States may factor such climatic
conditions and seasonal uses into their
use designations with appropriate
analyses. This would acknowledge that
a lower level of control, at lower
compliance cost, would be appropriate
to protect that use. Before modifying
any designated use, however, States
would need to evaluate the effect of less
stringent water quality criteria on
protecting other uses, including any
threatened or endangered species,
drinking water supplies and
downstream uses. EPA will further
evaluate these issues in the context of
the Water Quality Standards Regulation,
Advance Notice of Proposed Rule
Making (ANPRM), 63 FR, 36742, July 7,
1998.
  One of the major themes presented by
EPA in the ANPRM is that refinement
in use designations and tailoring of
water quality criteria to match refined
use designations is an important future
direction of the water quality standards
program. In assigning criteria to protect
general use classifications, a State or
Tribe must ensure that the criteria are
sufficiently protective to safeguard the
full range of waters of the State, i.e.,
criteria would be based on the most
sensitive use. This approach has been
disputed, especially for aquatic life
uses, where evidence suggests that the
general use criteria will require  controls
more stringent than needed to protect
the existing or potential aquatic life
community for a specific water body.
EPA recognizes that there is a growing
need to more precisely tailor use
descriptions and criteria to match site-
specific conditions, ensuring that uses
and criteria provide an appropriate level
of protection, which, to the extent
possible, are not overprotective. EPA  is
engaged in an ongoing evaluation of its
regulations in this area through the
ANPRM effort. At the same time, EPA
continues to encourage States and
Tribes to review the applicability of the
designated uses and associated criteria
using existing provisions in the water
quality standards regulation.

2. Total Maximum Daily Loads and
Analysis To Determine the Need for
Water Quality-Based  Limitations
  The development and implementation
of total maximum daily loads (TMDLs)
provide a link between water quality
standards and effluent limitations. CWA
section 303(d) requires States to develop
TMDLs to provide more stringent water
quality-based controls when technology-
based controls are inadequate to achieve
applicable water quality standards. A
TMDL is the sum of the individual
wasteload allocations for point sources
and load allocations for nonpoint
sources, with consideration for natural
background conditions. A TMDL
quantifies the maximum allowable
loading of a pollutant to a water body
and allocates this maximum load to
contributing point and nonpoint sources
so that water quality criteria will not be
exceeded and designated uses will be
protected. A TMDL also includes a
margin of safety to account for
uncertainty about the relationship
between pollutant loads and water
quality.
  Today's final rule refers to TMDLs in
several provisions. For the purpose of
today's rule, EPA relies on the
component of the TMDL that evaluates
existing conditions and allocates loads.
For discharges to waters that are not
impaired and for which a TMDL has not
been developed, today's rule also refers
to an "equivalent analysis." The
discussion that follows uses the term
"TMDL" for both.
  Under revised § 122.26(a)(9Ki)(C), the
permitting authority may designate

-------
 68790    Federal Register/Vol. 64, No. 235/Wednesday,  December  8, 1999/Rules and Regulations
 storm water discharges that require
 NPDES permits based on TMDLs that
 address the pollutants of concern. For
 storm water discharges associated with
 small construction activity,
 § 122.26(b)(15)(i)(B) provides a waiver
 provision where it may be determined
 that storm water controls are not needed
 based on TMDLs that address sediment
 and any other pollutants of concern.
 The NPDES permitting authority may
 waive requirements under the program
 for certain small MS4s within urbanized
 areas serving less than 1,000 persons
 provided that, if the small MS4
 discharges any pollutant that has been
 identified as a cause of impairment of a
 water body into which it discharges, the
 discharge is in compliance with a
 wasteload allocation in a TMDL for the
 pollutant of concern. The permitting
 authority may also waive requirements
 for MS4s in urbanized areas serving
 between 1,000 and 10,000 persons, if
 the permitting authority determines that
 storm water controls are not needed, as
 provided in § 123.35(d)(2).  See
 §122.32(c).
  Under CWA section 303(d), States
 identify which of their water bodies
 need TMDLs and rank them in order of
 priority. Generally, once a TMDL has
 been completed for one or more
 pollutants in a water body, a wasteload
 allocation for each point source
 discharging the pollutant(s) is
 implemented as an enforceable
 condition in the NPDES permit.
 Regulated small MS4s are essentially
 like other point source discharges for
 purposes of the TMDL process.
  A TMDL and the resulting wasteload
 allocations for pollutant(s) of concern in
 a water body may not be available
 because the water body is not on the
 State's 303(d) list, the TMDL has not yet
 been completed, or the TMDL did not
 include specific pollutants of concern.
 In these cases, the permitting authority
 must determine whether point sources
 discharge pollutant(s) in amounts that
 cause, have the reasonable potential to
 cause, or contribute to excursions above
 State water quality standards, including
 narrative water quality criteria. This so-
 called "reasonable potential" analysis is
 intended to determine whether and for
what pollutants water quality based
 effluent limits are required. The analysis
 is, in effect, a substitute for a similar
 determination that would be made as
part of a TMDL, where necessary. When
 "reasonable potential" exists,
regulations at § 122.44(d) require a-
water quality-based effluent limit for the
pollutant(s) of concern in NPDES
permits. The water quality-based
effluent limits may be narrative
requirements to implement BMPs or,
 where necessary, may be numeric
 pollutant effluent limitations.
   Commenters, generally from the
 regulated community, objected that, due
 to references to the need to develop a
 program "to protect water quality" and
 to additional NPDES permit
 requirements beyond the minimum
 control measures based on TMDLs or
 their equivalent, regulated small MS4s
 will be subject to uncertain permit
 limitations beyond the six minimum
 control measures. Commenters also
 asserted that through the imposition of
 a wasteload allocation under a TMDL in
 impaired water bodies, there is a
 likelihood that unattainable, yet
 enforceable narrative and numeric
 standards will be imposed on regulated
 small MS4s.
  As is discussed in the preceding
 section, NPDES permits  must include
 any more stringent limitations when
 necessary to meet water  quality
 standards. However,  even if a regulated
 small MS4 is subject to water quality
 based effluent limits, such limits may be
 in the form of narrative effluent
 limitations that require the
 implementation of BMPs. As discussed
 earlier, EPA has adopted the Interim
 Permitting Policy and incorporated it in
 the development of today's rule to
 recognize the appropriateness of BMP-
 based limits developed on a case-by-
 case basis.
  EPA formed a Federal  Advisory
 Committee to provide advice to EPA on
 identifying water quality-limited water
 bodies, establishing TMDLs for them as
 appropriate, and developing appropriate
 watershed protection programs for these
 impaired waters in accordance with
 C\VA section 303(d).  Operating under
 the auspices of the National Advisory
 Council for Environmental Policy and
 Technology (NACEPT), the committee
 produced its Report of the Federal
 Advisory Committee on the Total
 Maximum Daily Load (TMDL} Program
 (July 1998). EPA recently published a
 proposed rule to implement the Report's
 recommendations (64 FR 46012, August
 23, 1999).

 3. Anti-Backsliding
  In general, the term "anti-
backsliding" refers to statutory
provisions at CWA sections 303(d)(4)
and 402 (o) and regulatory provisions at
40 CFR 122.44(1).  These provisions
prohibit the renewal, reissuance, or
modification of an existing NPDES
permit that contain effluent limits,
permit terms, limitations and
conditions, or standards that are less
stringent than those established in the
previous permit. There are also
 exceptions to this prohibition known as
 "antibacksliding exceptions."
   The issue of backsliding from prior
 permit limits, standards, or conditions
 is not expected to initially apply to most
 storm water dischargers designated
 under today's proposal because they
 generally have not been previously
 authorized by an NPDES permit.
 However, the backsliding prohibition
 would apply if a storm water discharge
 was previously covered under another
 NPDES permit. Also, the backsliding
 prohibition could apply when an
 NPDES storm water permit is reissued,
 renewed, or modified. In most cases,
 however, EPA does not believe that
 these provisions would restrict revisions
 to storm water NPDES permits.
   One commenter questioned whether,
 if BMPs implemented by a regulated
 small MS4 operator fail to produce
 results in removal of pollutants and  the
 permittee attempts to substitute a more
 effective BMP, the small MS4 operator
 could be accused of violating the anti-
 backsliding provisions and also be
 exposed to citizen lawsuits. In response,
 EPA notes that in such circumstances
 the MS4's permit has not changed and,
 therefore, the prohibition against
 backsliding is not applicable. Further,
 any change in the mix of BMPs that was
 intended to be more effective at
 controlling pollutants would not be
 considered backsliding, even if it did
 not include all of the previously
 implemented BMPs.
 4. Water Quality-Based Waivers and
 Designations
  Several sections of today's final rule
 refer to water quality standards in
 identifying those storm water discharges
 that are and are not required to be
 permitted under today's rule. As  noted
 in § 122.30 of today's rule, CWA section
 402(p)(6) requires the designation of
 municipal storm water sources that
 need to be regulated to protect water
 quality and the establishment of a
 comprehensive storm water program to
regulate these sources. Requirements
 applicable to certain municipal sources
may be waived based on the absence of
 demonstrable water quality impacts.
 Section 122.32(c). The section 402(p)(6)
mandate to protect water quality also
provides the basis for regulating
 discharges associated with small
construction. See also §122.26(b)(15)(i).
Further, today's rule carries forward  the
existing authority for the permitting
authority to designate sources of storm
water discharges based upon water
quality considerations. Section
 122.26(a)(9)(i)(C) and (D).
  As is discussed above in sections
II.H.2.e (for small MS4s) and ILI.l.b.ii

-------
           Federal Register/Vol. 64, No. 235/Wednesday, December 8, 1999/Rules and  Regulations    68791
 (for small construction), the
 requirements of today's rule may be
 waived based on wasteload allocations
 that are part of "total maximum daily
 loads" (TMDLs) that address the
 pollutants of concern or, in the case of
 small construction and municipalities
 serving between 1,000  and 10,000
 persons, the equivalents of TMDLs. One
 commenter stated that  waivers would
 allow exemptions to the technology
 based requirements and would thus be
 inconsistent with the two-fold approach
 of the CWA (a technology based
 minimum and a water  quality based
 overlay). EPA acknowledges that
 \vaivers are not allowed for other
 technology-based requirements under
 the CWA. A more flexible approach is
 allowed, however, for sources
 designated for regulation under
 402(p)(6) to protect water quality. For
 such sources EPA may allow a waiver
 where it is demonstrated that an
 individual source does not present the
 threat to water quality that was the basis
 for EPA's designation.

 III. Cost-Benefit Analysis

  EPA has determined that the range of
 the rule's benefits exceeds the range of
 regulatory costs. The estimated rule
 costs range from $847.6 million to
 $981.3 million annually with
 corresponding estimated monetized
 annual benefits which range from
 S671.5 million to SI.628 billion,
 expected to exceed costs.
  The rule's cost and benefit estimates
 are based on an annual comparison of
 costs and benefits for a representative
 year (1998) in which the rule is
 implemented. This differs from the
 approach used for the proposed rule
 which projected cost and benefits over
 three permit terms. EPA has chosen to
 use the current approach because it
 determined that the ratio of annual
 benefits and costs would not change
 significantly over time. Moreover,
 because there is not an initial outlay of
 capital costs with benefits accruing in
 the future (i.e., benefits and costs are
 almost immediately at a steady state), it
 is not necessary to discount costs in
 order to account for a time differential.
   EPA developed detailed estimates of
 the costs and benefits of complying with
 each of the incremental requirements
 imposed by the rule. The Agency used
 two approaches, a national water quality
 model and national water quality
 assessment, to estimate the potential
 benefits of the rule. Both approaches
 show that the benefits are likely to
 exceed costs.
   These estimates, including
 descriptions of the methodology and
 assumptions used, are described in
 detail in the Economic Analysis of the
 Final Phase II Rule, which is included
 in the record  of this rule making.
 Exhibit 3 summarizes costs and benefits
 associated with the basic elements of
 today's rule.

A. Costs
1. Municipal Costs
  Initially, to determine municipal costs
for the proposed rule, EPA used
anticipated expenditure data included
in permit applications from a sample of
21 Phase I MS4s. Certain commenters
criticized the Agency for using
anticipated expenditures because they
could be significantly different from the
actual expenditures. These commenters
suggested that the Agency use the actual
cost incurred by the Phase I MS4s.
Other comments stated that because the
Phase I MS4s, in general, are large
municipalities, they may not be
representative of the Phase II MS4s for
estimating regulatory costs. Finally, one
commenter noted that the sample of 21
municipalities used to project cost was
relatively small.
  To address the concerns of the
commenters, EPA utilized a National
Association of Flood and Stormwater
Management Agencies (NAFSMA)
survey of the Phase II community to
obtain incremental cost estimates for
Phase II municipalities. Using the list of
potential Phase II designees published
in the Federal Register (63 FR 1616),
NAFSMA contacted more than 1,600
jurisdictions. The goal of the survey was
to solicit information from those
communities about the proposed Phase
II NPDES storm water program. Several
of the survey questions corresponded
directly to the minimum measures
required by the Phase II rule. One
hundred twenty-one surveys were
returned to NAFSMA and were used to
develop municipal costs.
  Using the NAFSMA information, EPA
estimated average annual per household
program costs for automatically
designated municipalities. EPA also
estimated an average annual per
household administrative cost for
municipalities to address application,
record keeping, and reporting
requirements of the Rule. The total
average per household cost of the rule
is expected to $9.16 per household.
  To determine potential national level
costs for municipalities, EPA multiplied
the number of households (32.5 million)
by the per household cost ($9.16). EPA
estimates the annual cost of the Phase
II municipal program at $298 million.
  As an alternative method, and point
of comparison, to the NAFSMA-based
approach, EPA reviewed actual
expenditures reported from 35 Phase I
MS4s. The Agency targeted these 35
Phase I MS4s because they had
participated in the NPDES program for

-------
68792    Federal Register / Vol. 64,  No. 235/Wednesday, December 8, 1999/Rules and Regulations
nearly one permit term, were smaller in
size and had detailed data reflecting
their actual program implementation
costs. Of the 35 MS4s, appropriate cost
data was only available for 26 of those
MS4s. EPA analyzed the expenditure
data and identified the relevant
expenditures, excluding costs presented
in the annual reports unrelated to the
requirements of the Rule. The cost range
and annual per household program
costs of $9.08 are similar to those found
using the NAFSMA survey data.
2. Construction Costs
  In order to estimate the rule's
construction-related cost on a national
level (the soil and erosion controls
(SEC) requirements of the rule and the
potential impacts of the post-
construction municipal measure on
construction), EPA estimated a per site
cost for sites of one, three, and five acres
and multiplied these costs by the total
number of estimated Phase II
construction starts across these size
categories.
  To estimate the percentage of starts
subject to  the soil and erosion control
requirements between 1 and 5 acres,
with respect to each category of building
permits (residential, commercial, etc.),
EPA initially used data from Prince
George's County (PGC), Maryland, and
applied these percentages  to national
totals. In the proposal, EPA recognized
that the PGC data may not be
representative of the entire country and
requested data that could be used to
develop better estimates of the number
of construction sites between 1 and 5
acres. EPA did not receive any
substantiated national data from
commenters.
  In view of the unavailability of
national data from commenters, EPA
made extensive efforts to collect
construction site data around the
country. The Agency contacted more
than 75 municipalities. EPA determined
that 14 of the contacted municipalities
had useable construction site data.
Using data from these 14 municipalities,
EPA developed an estimate of the
percentage of construction starts on one
to five acres. EPA then multiplied this
percentage by the number of building
permits issued nationwide to determine
the total number of construction starts
occurring on one to five acres. Finally,
to isolate the number of construction
starts incrementally regulated by Phase
II, EPA subtracted the number of
activities regulated under  equivalent
programs  (e.g., areas covered by the
Coastal Zone Act Reauthorization
Amendments of 1990, and areas covered
by equivalent State level soil and
erosion control requirements).
Ultimately, EPA estimated that 110,223
construction starts would be
incrementally covered by the rule
annually.
  EPA then used standard cost
estimates from Building Construction
Cost Data and Site Work Landscape
Cost Data (R.S. Means, 1997a and
1997b) to estimate construction BMP
costs for 27 model sites in a variety of
typical site conditions across the United
States. The model sites included three
different site sizes (one, three and five
acres), three slope variations (3%, 7%,
and 12%), and three soil erosivity
conditions (low, medium, and high).
EPA chose BMP combinations
appropriate to the model site
conditions. Based on the assumption
that any combination of site factors is
equally  likely to occur in a given site,
EPA developed average cost of sediment
and erosion control for all model sites.
EPA estimated that, on average, BMPs
for a 1 acre site will cost SI,206, for a
3 acre site $4,598 and for a 5 acre site
$8,709.
  EPA then estimated administrative
costs per construction site for the
following elements required under the
rule: Submittal of a notice of intent for
permit coverage; notification to
municipalities; development of a storm
water pollution prevention plan; record
retention; and submittal of a notice of
termination. EPA estimated the average
total administrative cost per site to be
$937.
  EPA also considered the cost
implications of NPDES permit
authorities  waiving the applicability of
requirements to storm water discharges
from small  construction sites based on
two different criteria involving water
quality impact and low rainfall. EPA
received comments stating that a waiver
would require a significant investment
in training or acquisition  of a
consultant. Based on comments
received, EPA eliminated one of the
waiver conditions involving low soil
loss threshold because it necessitated
use of the Revised Universal Soil Loss
Equation which could require extensive
technical expertise.
  Based on the opinions of construction
industry experts, EPA estimates that 15
percent  of the construction sites that
would otherwise be covered by today's
rule will be eligible to receive waivers.
Therefore, the Agency has excluded 15
percent  of the construction sites when
deriving costs of sediment and erosion
control. The average cost for sites to
qualify for the waiver is expected to be
$34 per site. The construction cost
analysis for the proposed rule did not
include any costs for the preparation
and submission of waiver applications
because EPA believed those costs would
be negligible. However, in response to
public comments, EPA has estimated
these potential costs.
  EPA has also estimated the potential
costs for construction site operators to
implement the post-construction
minimum measure. These are costs that
may be incurred by construction site
operators if the MS4 chooses to meet the
post-construction minimum measure by
requiring on-site structural, site-by-site
control of post-construction runoff.
Municipalities may select from an array
of structural and non-structural options
in implementing this measure, so the
potential costs to construction operators
is uncertain. Nonetheless, EPA
developed average annual BMP costs for
sites of one, three, five and seven acres.
EPA's analysis accounted for varying
levels of imperviousness that
characterize residential, commercial,
and institutional land uses. Nationwide,
these costs are expected to range from
$44 million to $178 million annually.
  Finally, to establish national
incremental annual costs for Phase II
construction starts, EPA multiplied the
total costs of compliance for the chosen
site size categories by the total number
of Phase II construction starts and added
post-construction costs. EPA estimates
the annual compliance cost to range
from $545 million to $678.7 million.
B. Quantitative Benefits
  In the Economic Analysis for the
proposed rule, a "top-down" approach
was used to estimate economic benefits.
Under this approach, the combined
economic benefits for wet weather
programs were estimated first, and then
were divided among various  water
programs on the basis of expert opinion.
As a result, the benefits estimates for an
individual program were rather
uncertain. Moreover, this approach was
inconsistent with the approach used to
estimate the cost of the proposed storm
water rule, which was developed using
municipal-based and cost-based data to
develop "bottom-up" costs. Therefore,
EPA decided to use a "bottom-up"
approach for estimating benefits of the
Phase II rule. To adequately reflect the
quantifiable benefits of the rule, EPA
used two different methods:  (1) National
Water Quality Model and (2) National
Water Quality Assessment.
  To monetize benefits in both
approaches, the Agency applied Carson
and Mitchell's (1993) estimates of
household willingness-to-pay (WTP) for
water quality improvement to estimates
of waters impaired by storm water
discharges. Carson and Mitchell's 1993
study reports the results of their 1983
national survey of WTP for incremental

-------
           Federal Register/Vol.  64, No. 235/Wednesday, December 8, 1999/Rules  and Regulations    68793
 improvements in fresh water quality.
 Carson and Mitchell estimate the WTP
 for three minimum levels of fresh water
 quality: boatable, fishable, and sizable.
 EPA adjusted the WTP amounts to
 account for inflation, growth in real per
 capita income, and increased attitudes
 towards pollution control. The adjusted
 WTP amounts for improvements in
 fresh water quality are $210 for
 boatable, S158 for fishable, and $177 for
 sizable. A brief summary of the national
 water quality model and national water
 quality assessment approaches follow.
 1. National Water Quality Model
   One approach EPA used to estimate
 the benefits of the Phase II municipal
 and construction site controls was the
 National Water Pollution Control
 Assessment Model (NWPCAM).
 NWPCAM estimates benefits of the
 storm water program at the national
 level, including the impact on small
 streams. This model estimates water
 quality and the resultant use support for
 the 632,000 miles of rivers and streams
 in the USEPA Reach  File Version 1
 (RFl), which covers the continental
 United States. The model analyzes
 water quality changes by stream reach.
 The parameters modeled in the
 NWPCAM are biological oxygen
 demand (BOD), total suspended solids
 (TSS), dissolved oxygen (DO), and fecal
 coliforms (FC).
  The model projects changes in water
 quality due to the Phase II municipal
 and construction site controls. To
 calculate the economic benefits of
 change in water quality, the number of
 households in the proximity of the
 stream reach are determined, by
 overlaying the model results on the •
 1990 Census of Populated Places and
 Minor Civil Divisions, and updating the
 population to 1998. Economic benefits
 are calculated using the Carson and
 Mitchell WTP values. The benefits are
 separately estimated for local and non-
 local waters on the basis of WTP values
 and proximity to water quality changes.
  The  value of the change in use
 support for local waters is greater than
 the value of the non-local waters
 because of the opportunity to use local
 waters by the local population. This
 model  assumes that if improvement
 occurs in waters that are not close to
 population centers the economic value
 is lower. Therefore, benefits are
 estimated for local and non-local waters
 separately. This assumption is based on
 Carson and Mitchell's survey which
 asked respondents to apportion each of
 their stated WTP values between
 achieving the water quality goals in
 their own State and achieving those
 goals in the nation as a whole. On
 average, respondents allocated 67% of
 their values to achieving in-State water
 quality goals and the remainder to the
 nation as a whole. Carson and Mitchell
 argue that for valuing local water quality
 changes 67% is a reasonable upper
 bound for the local multiplier and 33%
 for the non-local water quality changes.
 For the purposes of this analysis, the
 locality is defined as urban sites and
 associated populations linked into the
 NWPCAM framework. Using this
 methodology, the total monetized
 benefits of Phase II control of urban and
 construction site runoff is estimated to
 be $1.628 billion per year. The local and
 non-local benefits due to Phase II
 controls are presented in Exhibit 4.

  1 To estimate non-local willingness to pay per household, the 33% of willingness is multiplied by the fraction of previously impaired national wa-
ters (in each use category) that attain the beneficial use as a result of the Phase II rule, To estimate the aggregate non-local benefits, non-local
willingness to pay is multiplied with the total number oi households in the US.
  While the numbers of miles that are
estimated to change their use support
are small, the benefits estimates are
quite significant. This is because urban
runoff and, to a large extent,
construction activity occurs where the
people actually reside and the water
quality changes mostly occur close to
these population centers. NWPCAM
indicates that changes in pollution loads
have the most effect immediately
downstream of pollution changes. As a
result, the aggregate WTP is large
because large numbers of households in
these population centers are associated
with the local waters that reflect
improvement in designated use support.
2. National  Water Quality Assessment
  EPA also estimated benefits of the
Phase II Storm Water program using the
1998 National Water Quality Inventory
(305(b)) Report to Congress, rather than
the NWPCAM as a basis for estimating
impairment addressed by the rule. The
Water Quality Assessment method
separately estimates benefits associated
with improvements to fresh water,
marine water and construction site
controls, and then aggregates these
separate categories into an estimate of
total annual benefits.
a. Municipal Measures

/. FresA Waters Benefits

  In order to develop estimates for the
potential value of the municipal
measures (except storm water runoff
controls for construction sites), EPA
applied Carson & Mitchell WTP values
to estimated existing and projected
future fresh water impairment. Carson &
Mitchell did not evaluate marine waters,
so only fresh water values were
available from their research. Even
though the Carson and Mitchell
estimates apply to all fresh water, it is
not clear how these values would be
apportioned among rivers, lakes, and
the Great Lakes. The 305(b) data
indicate that lakes are the most
impaired by urban runoff/storm sewers,
followed closely by the Great Lakes, and
then rivers. Therefore, EPA applied the
WTP values to the categories separately
and assumed that the higher resulting
value for lakes represents the high end
of the range  (i.e., assuming that lake
impairment  is more indicative of
national fresh water impairment) and
that the lower resulting value for
impaired rivers represents the low end
of a value range for all fresh waters (i.e.,
assuming that river impairment is more
indicative of national fresh water
impairment). In addition, EPA estimated
that the post-construction runoff

-------
68794    Federal Register/Vol.  64, No. 235/Wednesday, December 8, 1999/Rules and Regulations
requirements of the municipal program
might result in benefits of at least S16.8
million annually from avoided future
runoff. The post-construction estimate
significantly underestimates potential
program benefits because it does not
account for avoided hydrologic changes
and resulting water quality impairment
associated with increases in
imperviousness from development and
redevelopment. Summing the benefits
across the water quality use support
levels yields an estimate of benefits
ranging from approximately $121.9
million to $378.2 million per year.

ii. Marine Waters Benefits

  In addition to the fresh water benefits
captured by the Carson and Mitchell
study, EPA anticipates benefits as a
result of improvements to marine
waters. Sufficient methods have not
been developed to quantify national-
level benefits for commercial or
recreational fishing. EPA used beach
closure data and visitation estimates
from its Beach Watch Program to
estimate potential reductions in marine
swimming visits due to storm water
runoff contamination events in 1997.
The estimated 86,100 trips that did not
occur because of beach closures in
coastal Phase II communities is a lower
bound because it represents only those
beaches that report both closures and
visitation data. EPA estimates potential
swimming benefits from the rule to be
at least $2.1 million annually.
  EPA developed an analysis of
potential benefits associated with
avoided health impacts from exposure
to contaminants in storm sewer effluent.
Based on a study of incremental
illnesses found among people who
swam within one yard of storm drains
in Santa Monica Bay, EPA estimated a
range of incremental illnesses (Haile et
al.,  1996). Depending on assumptions
made about number of exposures to
contaminants and contaminant
concentrations, benefits ranged from
$7.0 million to $29.9 million annually.

b. Construction Benefits

  The major pollutant resulting from
construction activities is sediment.
However,  in addition to sediment,
construction activities also yield
pollutants such as pesticides, petroleum
products,  and solvents. Because
circumstances will vary considerably
from site to site, data is not available
with which to develop estimates of
benefits for each site and aggregate to
obtain a national-level estimate.
  In the proposed rule, EPA estimated
the  combined benefits of all wet weather
programs, and then used expert
opinions to allocate them to different
individual programs. To eliminate the
possible overlap between the benefits of
the  soil and erosion control
requirements, municipal measures, and
other wet  weather storm water
programs, EPA chose to use an approach
in today's final rule that directly
estimates the benefits of soil and erosion
requirements.
  A survey of North Carolina residents
(Paterson et al., 1993) indicated that
households are wiling to pay for
erosion and sediment controls similar to
those in today's rule. Based on income
and other indicators, the values derived
from the study are expected to be
similar to values held in the rest of the
country.  Using the mean value of the
willingness to pay of $25 per household,
EPA projects  annual benefits  of the soil
and erosion requirements to range from
$540.5-3686  million.

c. Summary of Benefits From the
National Water Quality Assessment
  Total benefits from municipal
measures and construction site controls
are expected to range from $671.5
million to $1.1 billion per year,
including benefits of approximately
$13..7 million per year associated with
small stream improvements. A summary
of the potential benefits is presented in
Exhibit 5.
  As shown in Exhibit 5, it was not
possible to monetize all categories of
benefits using the WTP estimates. In
particular, benefits for improving
marine water quality such as  fishing and
passive use benefits are not included in
the values used to estimate the potential
benefits of the municipal minimum
measures (excluding construction sites
controls), and they are not estimated
separately, because information is not
currently available.

  2 Based on research by Carson and Mitchell (1993). Fresh water value only. Does not include commercial fishery, navigation, or diversionary
(e.g. municipal drinking water cost savings or risk reductions) benefits. May not fully capture human health risk reduction or ecological values.
  3 Based on research by Paterson et al (1993). Although the survey's description of the benefits of reducing soil erosion from construction sites
included reduced dredging, avoided flooding, and water storage capacity benefits, these benefit categories may not be fully incorporated in the
WTP values. Small streams may account for over 2% of total benefits.
C. Qualitative Benefits
  There are additional benefits to storm
water control that cannot be quantified
or monetized. Thus, the current estimate
of monetized benefits may understate
the true value of storm water controls
because it omits many ways in which
society is likely to benefit from reduced
storm water pollution, such as improved

-------
            Federal Register/Vol. 64. No.  235/Wednesday, December  8,  1999/Rules and Regulations    68795
 aesthetic quality of waters, benefits to
 wildlife and to threatened and
 endangered species, cultural values, and
 biodiversity benefits.
   A benefit that EPA did not monetize
 completely is the flood control benefits
 attributable to municipal storm water
 controls reducing downstream flooding,
 although flood control benefits
 associated with sediment and  erosion
 control are already reflected to some
 extent in the construction benefits.
 Similarly, the Agency could not value
 the benefits from increased property
 value due to storm water controls
 reflected in the rule, even though a
 commenter suggested inclusion of these
 benefits in the estimates.
   Moreover, while a number of
 commenters requested that EPA include
 ecological benefits, the Agency was not
 able to fully monetize these benefits.
 Urbanization usually increases the
 amount of sediment, nutrients, metals
 and other pollutants associated with
 land disturbance and development.
 Development usually not only results in
 a dramatic increase in the volume of
 water runoff, but also in a substantial
 decrease in that water's quality due to
 stream scour, runoff and dispersion of
 toxic pollutants, and oversiltation.
 These kinds of secondary benefits could
 not be fully reflected in the monetized
 benefits. EPA was able to only  monetize
 the aquatic life support benefits for
 waters assumed to be impaired. Thus,
 only the aquatic life support benefits
 attributable to municipal controls,
 reflected through human satisfaction,
 are taken into account.
  Reduced nutrient level is another
 benefit of the storm water control which
 is not fully captured by the economic
 analysis. High nutrient levels often lead
 to eutrophication of the aquatic system.
The quality change in ecological sources
as the result of storm water controls to
reduce pollutants is not fully reflected
in the present benefits.
D, National Economic Impact
  Finally, the Agency determined that
the rule will have minimal impacts on
 the economy or employment. This is
 because the final rule regulates small
 MS4s and construction sites under 5
 acres, not the typical industrial plants or
 other non-construction activities that
 could directly impact production and
 thus  those sectors of the economy.
   Discussions with representatives
 within the construction industry
 indicate that construction costs will
 likely be passed on to buyers, thus not
 seriously affecting the housing industry
 directly. One commenter argued that the
 rule will have a negative employment
 effect because the builders will build
 fewer homes requiring less building
 materials as a result of the declining
 demand induced  by the cost of the soil
 and erosion controls. EPA disagrees
 with  this argument because the cost  of
 the controls, as the percentage of the
 price of a median home, is negligible
 and will be passed on to final buyers.
   Flexibility within the rule allows
 MS4s to  tailor the storm water program
 requirements to their needs and
 financial position, minimizing impacts.
 For sedimentation and erosion controls
 on construction sites, the  rule
 contemplates application of commonly
 used  BMPs to reduce costs for the
 construction industry; Thus, the rule
 attempts to use existing practices to
 prevent pollution, which should
 minimize impacts on States, Tribes,
 municipalities and the construction
 industry.
  Thus, EPA concludes that the effect of
 the rule,  if any, on the national economy
 will be minimal. The benefits of today's
 rule more than offset any cost impacts
 on the national economy.

 IV. Regulatory Requirements
 A. Paperwork Reduction Act
  The Office of Management and Budget
 (OMB) has approved some of the
 information collection requirements
 contained in this final rule (i.e. those
found in  40 CFR 122.26(g) and
 123.35(b)) under the provisions of the
Paperwork Reduction Act, 44 U.S.C.
 3501 et seq. and has assigned OMB
control number 2040-0211.
   The burden and costs described below |
 are for the information collection,
 reporting, and record keeping
 requirements for the three year period
 beginning with the effective date of
 today's rule. Additional information
 collection requirements for regulated
 small MS4s and small construction sites
 will, occur after this initial three year
 period and will be counted in a
 subsequent information collection
 requirement. The total burden of the
 information collection requirements for
 the first three years of this rule is
 estimated at 56,369 hours with a
 corresponding cost of $2,151,305
 million annually. This burden and cost
 is for industrial facilities to complete
 and submit the no exposure
 certification, for NPDES-authorized
 States to process and review the no
 exposure certification, and for the
 NPDES-authorized States to develop
 designation criteria and assess
 additional MS4s outside of urbanized
 areas. Compliance with the applicable
 information collection requirements
 imposed under this rule are mandatory,
 pursuant to CWA section 402.
  Exhibit 6 presents average annual
 burden and cost estimates for Phase II
 respondents for the first three years.
 Burden means the total time, effort, or
 financial resources expended by persons
 to generate, maintain, retain, disclose or
 provide information to or for a Federal
 agency. This includes the time needed
 to review instructions; develop, acquire,
 install, and utilize technology and
 systems for the purposes of collecting,
 validating, and verifying information,
processing and maintaining
 information, and disclosing and
providing information; adjust existing
ways for complying with any previously
applicable instructions and
requirements; train personnel to be able
to respond  to a collection of
information; search  data sources;
complete and review the collection of
information; and transmit or otherwise
disclose the information.

tories. The burden and cost estimates provided  in this section are for the NPDES-authorized States in their role as the permitting authority for
municipal designations and industrial no exposure.
  4 The number of respondents for this activity,  15, represents the number of NPDES-authorized States and Territories that must develop des-
ignation criteria and assess small MS4s located  outside of an urbanized area for possible  Phase II coverage divided by the three year ICR pe-
riod.
  Given the requirements of today's
regulation, EPA believes there will be
no capital startup and no operation and
maintenance costs associated with
information collection requirements of
the rule.
  The government burden associated
with today's rule will impact State,
Tribal, and Territorial governments
(NPDES-authorized governmental
entities) that have storm water program
authority, as well as the federal
government (i.e., EPA), where it is the
NPDES permitting authority. As of
March 1999, 43 States and the Virgin
Islands had NPDES authority.
  The annual burden imposed upon
authorized governmental entities
(delegated States and the Virgin Islands)
and the federal government for the next
three years is estimated to be 19,992
hours ($537,985) and 4,087 hours
(3115,948) respectively, for a total of
24,079 hours ($653,933). This estimate
is based on the average time that
governments will expend to carry out
the following activities: designate
additional MS4s (332.8 hours) and
process and review "no exposure"
certificates from industrial dischargers
(0.5 hour).
  Under the existing rule, storm water
discharges from light industrial
activities identified under
§ 122.26(b)(14)(xi) were exempted from
the permit application requirements if
they were not exposed to storm water.
Today's rule expands the applicability
of the "no exposure" exclusion to
include all industrial activity regulated
under § 122.26(b)(14) (except category
(x), construction). The "no exposure"
provision is applied through the use of
a written certification process, thus
representing a slight reporting burden
increase for "light" industries with "no
exposure'.
  In addition to the information
collection, reporting, and record
keeping burden for the next three years,
today's rule contains information
collection requirements that will not
begin until three years or more from the
effective date of today's rule. These
information collection requirements
were not included in the information
collection request approved by OMB.
EPA will submit these burden estimates
for OMB approval when it submits ICR
2040-0211 to OMB for renewal in three
years. The rule burdens for regulated
small MS4s and small construction sites
that will be included in the ICR renewal
fall into three areas: application for an
NPDES permit or submittal of waiver
information, record keeping of storm
water management activities, and
submittal of reports to the permitting
authority.  There will also be an
additional burden for the permitting
authority to review this information.
  An  agency may not conduct or
sponsor, and a person is not required to
respond to a collection of information
unless it displays a currently valid OMB
control number. The OMB control
numbers for EPA's regulations are listed
in 40  CFR Part 9 and 48 CFR Chapter
15. EPA is amending the table in 40 CFR
Part 9 of currently approved ICR control
numbers issued by OMB for various
regulations to list the first three years of
information requirements contained in
this final rule.
B. Executive Order 12866

  Under Executive Order 12866, [58 FR
51,735 (October 4, 1993)] the Agency
must  determine whether the regulatory
action is "significant" and therefore
subject to  OMB review and the
requirements of the Executive Order.
The Order defines "significant
regulatory action" as one that is likely
to result in a rule that may:
  (1) have an annual effect on the
economy of $100 million or more or
adversely affect in a material way the
economy, a sector of the economy,
productivity, competition, jobs, the
environment, public health or safety, or
State, local, or tribal governments or
communities;
  (2) create a serious inconsistency or
otherwise interfere with an action taken
or planned by another agency;
  (3) materially alter the budgetary
impact of entitlements, grants, user fees,
or loan programs or the rights and
obligations of recipients thereof; or
  (4) raise novel legal or policy issues
arising out  of legal mandates, the
President's priorities, or the principles
set forth in the Executive Order.
  Pursuant to the terms of Executive
Order 12866, it has been determined
that this rule is a "significant regulatory
action". As such, this action was
submitted to OMB for review. Changes
made in response to OMB suggestions or
recommendations will be documented
in the public record.
C. Unfunded Mandates Reform Act
  Title II of the Unfunded Mandates
Reform Act of 1995 (UMRA), Public
Law 104-4, establishes requirements for
Federal agencies to assess the effects of
their regulatory actions on State, local,
and tribal governments and the private
sector. Under section 202 of the UMRA,
EPA generally must prepare a written
statement, including a cost-benefit
analysis, for proposed and final rules
with "Federal mandates" that may
result in expenditures to State, local,
and tribal governments, in the aggregate,
or to the private  sector, of $100 million
or more in  any one year. Before
promulgating an EPA rule for which a

-------
           Federal  Register/Vol. 64, No. 235/Wednesday, December 8,  1999/Rules and Regulations    68797
written statement is needed, section 205
of the UMRA generally requires EPA to
identify and consider a reasonable
number of regulatory alternatives and
adopt the least costly, most cost-
effective or least burdensome alternative
that achieves the objectives of the rule.
The provisions of section 205 do not
apply when they are inconsistent with
applicable law. Moreover, section 205
allows EPA to adopt an alternative other
than the least costly, most cost-effective
or least burdensome alternative if the
Administrator publishes with the final
rule an explanation why that alternative
was not adopted.
  EPA has determined that today's rule
contains a Federal mandate that may
result in expenditures of S100 million or
more in any one  year for both State,
local, and tribal governments, in the
aggregate, and the private sector.
Accordingly, EPA has prepared under
section 202 of the UMRA a written
statement which is summarized below.
1. Summary of UMRA Section 202
Written Statement
  EPA promulgates today's storm water
regulation pursuant to the specific
mandate of Clean Water Act section
402(p)(6), as well as sections 301, 308,
402, and 501. (33 U.S.C. sections
1342(p)(6), 1311, 1318,  1342, 1361.)
Section 402(p)(6) of the CWA requires
that EPA designate sources to be
regulated to protect water quality and
establish a comprehensive program to
regulate those sources.
  In the Economic Analysis of the Final
Phase IIRule (EA), EPA describes the
qualitative and monetized benefits
associated with today's rule and then
compares the monetized benefits with
the  estimated costs for the rule. EPA
developed detailed estimates of the
costs and benefits of complying with
each of the incremental requirements
imposed by the rule. These estimates,
including descriptions of the
methodology  and assumptions used, are
described in detail in the EA. The
Agency used two approaches, a national
water quality model and national water
quality assessment, to estimate the
potential benefits of the rule. Both
approaches show that the benefits are
likely to exceed costs. Exhibit 3 in
section III of this preamble summarizes
the  costs and  benefits associated with
the  basic elements of today's rule.
  There are additional benefits to storm
water control that cannot be quantified
or monetized. Thus, the current estimate
of monetized  benefits may understate
the  true value of storm water controls
because it omits many ways by which
society is likely to benefit from reduced
storm water pollution, such as improved
aesthetic quality of waters, benefits to
wildlife and to threatened and
endangered species, cultural values, and
biodiversity benefits.
  Several commenters asserted that
today's rule is an unfunded mandate
and that, without funding,  the
monitoring of the already existing
pollution control programs would
suffer. In section II.D.3 of the preamble,
EPA lists some of the programs that EPA
anticipates may provide funds to help
develop and, in limited circumstances,
implement storm water management
programs.
  In the EA, EPA reviewed the expected
effect of today's rule on the national
economy. The Agency determined that
the rule will have minimal impacts on
the economy or employment. This is
because the final rule regulates small
MS4s and construction sites under 5
acres, not the typical industrial plants or
other non-construction activities that
could directly impact production and
thus those sectors of the economy.
  Discussions with representatives
within the construction industry
indicate that construction costs will
likely be passed on to buyers, thus not
seriously affecting the housing industry
directly. Flexibility within  the rule
allows MS4s to tailor the storm water
program requirements to their needs
and financial position, minimizing
impacts. For sedimentation and erosion
controls on construction sites, the rule
contemplates application of commonly
used BMPs to reduce costs  for the
construction industry. Thus, the rule
attempts to use existing practices to
prevent pollution, which should
minimize impacts on States, Tribes,
municipalities and the construction
industry.
  Thus, EPA concludes that the effect of
the rule, if any, on the national economy
would be minimal. The benefits of
today's rule more than offset any cost
impacts on the national economy.
  Consistent with the intergovernmental
consultation provisions of section 204 of
the UMRA and Executive Order 12875,
"Enhancing the Intergovernmental
Partnership," EPA consulted with the
governmental entities affected by this
rule.
  First, EPA provided States, Tribal and
local governments with the opportunity
to comment on draft alternative
approaches for the proposed rule
through publishing a notice requesting
information and public comment in the
Federal Register on September 9,1992
(57 FR 41344). This notice presented a
full range of regulatory alternatives. At
that time, EPA received more than 130
comments,  including approximately 43
percent from municipalities and 24
percent from State or Federal agencies.
These comments were the genesis of
many of the provisions in the today's
rule, including reliance on the NPDES
program framework (including general
permits), providing State and local
governments flexibility in selecting
additional sources requiring regulation,
and focusing on high priority polluters.
These comments helped to focus on
pollution prevention, watershed-based
concerns and BMPs. They also led to
certain exemptions for facilities that do
not pollute national waters.
  In early 1993, EPA, in conjunction
with the Rensselaerville Institute, held
public and  expert meetings to assist in
developing and analyzing options for
identifying unregulated storm water
sources and possible controls. These
meetings provided participants an
additional opportunity to provide input
into the CWA section 402(p)(6) program
development process. The final rule
addresses several of the key concerns
identified in these groups, including
provisions that provide flexibility to the
States to select sources to be controlled
and types of permits to be issued, and
flexibility to MS4s in selecting BMPs.
  EPA also conducted outreach with
representatives of small entities,
including small government
representatives, in conjunction with the
convening of a Small Business
Advocacy Review Panel under SBREFA
which is discussed in section IV.E. of
the preamble.
  In addition, EPA established the
Urban Wet Weather Flows Advisory
Committee  under the Federal Advisory
Committee  Act (FACA). The Urban Wet
Weather Flows Advisory Committee, in
turn established the  Storm Water Phase
II Subcommittee. Consistent with
FACA, the membership of the
Committee  and the Storm Water Phase
II Subcommittee was balanced among
EPA's various outside stakeholder
interests, including representatives from
State governments, municipal
governments (both elected officials and
appointed officials) and Tribal
governments, as well as industrial and
commercial sectors,  agriculture,
environmental and public interest
groups.
  In general, municipal and Tribal
government representatives supported
the NPDES  approach in today's rule for
the following reasons: It will be
uniformly applied on a nationwide
basis; it provides flexibility  to allow
incorporation of State and local
programs; it resolves the problem of
donut holes that cause water quality
impacts in urbanized areas; and  it
allows co-permitting of small regulated

-------
68798    Federal Register/Vol. 64, No.  235/Wednesday, December 8,  1999/Rules  and Regulations
MS4s with those regulated under the
existing storm water program.
  In contrast, State representatives
sought alternative approaches for State
implementation of the storm water
program for Phase II sources. State
representatives asserted that a non-
NPDES alternative approach best
facilitated watershed management and
avoided duplication and overlapping
regulations. These representatives
pointed out that there are a variety of
State programs—not based on the
CWA—implementing effective storm
water controls, and that EPA should
provide incentives for their
implementation and improvement in
performance. EPA continues to believe
that an NPDES approach is the best
approach in order to adequately protect
water quality. However, EPA has
worked with States on an alternative
approach that provides flexibility
within the NPDES framework. The final
rule allows States with a watershed
permitting approach to phase in permit
coverage for MS4s in jurisdictions with
a population less than 10,000 and
provides two waivers from coverage for
small MS4s. This issue is discussed in
section II.C of the preamble, Program
Framework: NPDES Approach.
  Some municipal governments
objected that the rule's  minimum
measures for small MS4s violate the
Tenth Amendment insofar as they
require the operators of MS4s to regulate
third parties according  to the
"minimum measures" for municipal
storm water management programs. EPA
disagrees that today's rule is
inconsistent with Tenth Amendment
principles. Permits issued under today's
rule will not compel political
subdivisions of States to regulate in
their sovereign capacities, but rather to
effectively control discharges out of
their storm sewer systems in their
owner/operator capacities. For MS4s
that do not accept this "default"
minimum measures-based approach (to
control discharges out of the storm
sewer system by  exercising local powers
to control discharges into the storm
sewer system), today's rule allows for
alternative permits through individual
permit applications. EPA made
revisions to the rule to allow regulated
small MS4s to opt out of the minimum
measures approach and instead apply
for an individual permit. This issue is
discussed in section II.H.S.c.iii of the
preamble, Alternative Permit Option/
Tenth Amendment.
2. Selection of the Least Costly, Most
Cost-Effective or Least Burdensome
Alternative That Achieves the
Objectives of the Statute
  Today's rule evolved over time and
incorporated aspects of alternatives that
responded to concerns presented by the
various stakeholders. A primary
characteristic of today's rule is the
flexibility it offers both the permitting
authority and the regulated sources
(small MS4s and small construction
sites), by the use of general permits,
implementation of BMPs suited to
specific locations, and allowing MS4s to
develop their own program goals.
  In the administrative record
supporting  the proposed rule, EPA
estimated ranges of costs associated
with six different options, including a
no action option, the proposed option,
and four other options that considered
various combinations of the following:
Covering all the unregulated
construction sites below 5 acres, all
small MS4s, certain industrial and
commercial activities, and all point
sources. EPA developed detailed cost
estimates for the incremental
requirements imposed under the final
regulation,  and for each of the
alternatives, and applied these estimates
to the remaining unregulated point
sources of storm water. The Agency
compared the estimated annual range of
costs imposed under today's rule and
other major options considered. The
range of values for each option included
the costs for compliance, including
paperwork  requirements for the
operators of small construction sites,
industrial facilities, and MS4s and
administrative costs for State and  '
Federal NPDES  permitting authorities.
  Today's rule reflects the least costly
option  that  achieves the objectives of
the statute,  thus meeting the
requirements of section 205. EPA did
not consider "no regulation"  to be an
"option" because it would not achieve
the objectives of CWA section 402(p)(6).
A portion of currently unregulated point
sources of storm water need to reduce
pollutants to protect water quality.
  Today's rule is estimated to range in
cost from $847.6 million to S981.3
million annually, although the cost
estimate for the proposed rule was
reported as a range of $138 to $869
million annually. That range  reflected a
unit cost range for the municipal
minimum measures and a cost range per
construction site for soil erosion control.
EPA has since revised its cost analysis
to allow it to report the current estimate,
which  is toward the high end of the
original cost range. The four other
regulatory options considered at
proposal involved higher regulatory
costs and, therefore, were not selected.
These four options and their estimated
costs are as follows: •
  (1) An option based on the August 7,
1995 direct final rule was estimated to
cost between $2.2 billion and $78.9
billion per year.
  (2) A "Plan B" option was estimated
to cost between $0.6 billion and $3.2
billion per year.
  (3) An option based'on the September
30,  1996 draft proposed rule was
estimated to cost between $0.2 billion
and $3.7 billion per year.
  (4) An option based on the February
13,1997 draft proposed rule, was
estimated to cost between $0.2 billion
and $3.5 billion.
  There are three reasons why the costs
for these four options exceeded the
estimated cost range for the proposed
rule. The first two options regulated
substantially more municipal
governments. The first, third, and fourth
options required industrial facilities to
apply for permits. Finally, the first three
options applied permit requirements to
construction sites below 1 acre.
Consequently, these options would be
more costly than today's rule even with
the  revised analysis methods used to
estimate costs.

3. Effects on Small Governments
  Before EPA establishes any regulatory
requirements that may significantly or
uniquely affect small governments,
including tribal governments, it  must
have developed under section 203 of the
UMRA a small government agency plan.
The plan must provide for notifying
potentially affected small governments,
enabling officials of affected small
governments to have meaningful and
timely input in the development of EPA
regulatory proposals with significant
Federal intergovernmental mandates,
and informing, educating, and advising
small governments on compliance with
the  regulatory requirements. EPA has
determined that this rule contains no
regulatory requirements that might
significantly or uniquely affect small
governments. Although today's rule
expands the NPDES program (with
modifications) to certain MS4s serving
populations below 100,000 and
although many MS4s are owned by
small governments, EPA does not
believe today's rule significantly or
uniquely affects small governments. As
explained in section IV.E. of the
preamble, EPA today certifies that the
rule will not have a significant impact
on small governmental jurisdictions. In
addition, the rule will not have a unique
impact on small governments because
the  rule will affect small governments in

-------
          Federal Register/Vol. 64, No. 235/Wednesday, December 8, 1999/Rules  and Regulations    68799
to the same extent as (or to a lesser
extent than) larger governments that are
already covered by the existing storm
water rules. Thus.'today's rule is not
subject to the requirements of section
203 of UMRA.
  Notwithstanding this finding, in
developing today's rule, EPA provided
notice of the requirements to potentially
affected small governments; enabled
officials of affected small governments
to provide meaningful and timely input
in the development of regulatory
proposals; and informed, educated and
advised small governments on
compliance with the requirements.
  Concerning notice. EPA provided
States, local, and Tribal governments
with the opportunity to comment on
alternative approaches for an early draft
of the proposed rule by publishing a
notice requesting information and
public comment in the Federal Register
on September 9,1992 (57 FR 41344).
This notice presented a full range of
regulatory alternatives. At that time,
EPA received more than 130 comments,
including approximately 43 percent
from municipalities and 24 percent from
State or Federal agencies.
  The Agency also provided, through
the SBREFA panel process and the
FACA process, the opportunity for
elected officials of small governments
(and their representatives) to
meaningfully participate in the
development of the rule. Through such
participation and exchange, EPA not
only notified potentially affected small
governments of requirements of the
developing rule, but also allowed
officials of affected small governments
to have meaningful and timely input
into the development of regulatory
proposals.
  In addition to involving
municipalities in the development of
the rule, EPA also continues to inform,
educate, and advise small governments
on compliance with the requirements of
today's rule. For example, EPA
supported 10 workshops, presented by
the American Public Works Association
from September 1998 through May
1999, designed to educate local
governments on the implementation of
the rule. The workshop curriculum
included information on a variety of key
issues such as anticipated regulatory
requirements, agency reporting, best
management practices, construction site
controls, post construction management
for new and redeveloped sites, public
education and public involvement
strategies, detection and control of illicit
discharges, and good housekeeping
practices. Moreover, EPA has prepared
a series of fact sheets, available on the
EPA website at www.epa.gov/owm/sw/
toolbox, that explains the rule in detail.
  Finally, to assist small governments in
implementing the Phase II program,
EPA is committed to the following: (1)
developing a tool box of implementation
strategies; (2) providing written
technical assistance, including guidance
on developing BMPs and measurable
goals; and (3) compiling a
comprehensive evaluation of the NPDES
municipal storm water Phase II program
over the next 13 years.

D. Executive Order 13132
  Executive Order 13132, entitled
"Federalism" (64 FR 43255, August 10,
1999), requires EPA to develop an
accountable process to ensure
"meaningful and timely input by State
and local officials in the development of
regulatory policies that have federalism
implications." "Policies that have
federalism implications" is defined in
the Executive Order to include
regulations that have "substantial direct
effects on the States, on the relationship
between the national government and
the States, or on the distribution of
power and responsibilities among the
various levels of government." Under
Executive Order 13132, EPA may not
issue a regulation that has federalism
implications, that imposes substantial
direct compliance costs, and that is not
required by statute, unless the Federal
government provides the funds
necessary to pay the direct compliance
costs incurred by State and local
governments, or EPA consults with
State and local officials early in the
process of developing the proposed
regulation. EPA also may not issue a
regulation that has federalism
implications and that preempts State
law unless the Agency consults with
State and local officials early in the
process of developing the proposed
regulation.
  If EPA complies by consulting,
Executive Order 13132 requires EPA to
provide to the Office of Management
and Budget (OMB), in a separately
identified section of the preamble to the
rule, a federalism summary impact
statement (FSIS). The FSIS must include
a description of the extent of EPA's
prior consultation with State and local
officials, a summary of the nature of
their concerns and the agency's position
supporting the need to issue the
regulation,  and a statement of the extent
to which the concerns of State and local
officials have been met. For final rules
subject to Executive Order 13132, EPA
also must submit to OMB a statement
from the agency's Federalism Official
certifying that EPA has fulfilled the
Executive Order's requirements.
  EPA has concluded that this final rule
may have federalism implications. As
discussed above in section IV.C., the
rule contains a Federal mandate that
may result in the expenditure by State,
local and tribal governments, in the
aggregate, of $100 million or more in
any one year. Accordingly, the rule may
have substantial direct effects on the
States; on the relationship between the
national government and the States, or
on the distribution of power and
responsibilities among the various
levels of government, as specified in
Executive Order 13132. Moreover, the
rule will impose substantial direct
compliance costs on State or local
governments. Accordingly, EPA
provides the following FSIS under
section 6(b) of Executive Order 13132.

1. Description of the Extent of the
Agency's Prior Consultation with State
and Local Governments
  Although this rule was proposed long
before the November 2,1999 effective
date of Executive Order 13132, EPA
consulted extensively with affected
State and local governments pursuant to
the intergovernmental consultation
provisions of Executive Order 12875,
"Enhancing the Intergovernmental
Partnership" (now revoked by Executive
Order 13132) and section 204 of UMRA.
  First, EPA provided State and local
governments the opportunity to
comment on draft alternative
approaches for the proposed rule
through publishing a notice requesting
information and public comment in the
Federal Register on September 9, 1992
(57 FR 41344).  This notice presented  a
full range of regulatory alternatives. At
that time, EPA received more than 130
comments, including approximately 43
percent from municipalities and 24
percent from State or Federal agencies.
These comments were the genesis of
many of the provisions in the today's
rule, including reliance on the NPDES
program framework (including general
permits), providing State and local
governments flexibility in selecting
additional sources requiring regulation,
and focusing on high priority polluters.
These comments helped to focus on
pollution prevention, watershed-based
concerns and BMPs. They also led to
certain exemptions for facilities that do
not pollute national waters.
  In early 1993, EPA, in conjunction
with the Rensselaerville Institute, held
public and expert meetings to assist in
developing and analyzing options for
identifying unregulated storm water
sources and possible controls. These
meetings provided participants an
additional opportunity to provide input
into the CWA section 402(p)(6) program

-------
68800    Federal Register/Vol. 64, No.  235/Wednesday,  December  8, 1999/Rules and Regulations
development process. The final rule
addresses several of the key concerns
identified in these groups, including
provisions that provide flexibility to the •
States to select sources to be controlled
and types of permits to be issued, and
flexibility to MS4s in selecting BMPs.
  EPA also conducted outreach with
representatives of small entities,
including small governments, in
conjunction with the convening of a
Small Business Advocacy Review Panel
under SBREFA which is discussed in
section III.F. of the preamble.
  In addition, EPA established the
Urban Wet Weather Flows Advisory
Committee (FACA), which in turn
established the Storm Water Phase II
Subcommittee. Consistent with the
Federal Advisory Committee Act, the
membership of the Committee and the
Storm Water Phase II Subcommittee was
balanced among EPA's various outside
stakeholder interests, including
representatives from State governments,
municipal governments (both elected
officials and appointed officials) and
Tribal governments, as well as
industrial and commercial sectors,
agriculture, environmental and public
interest groups.

2. Summary of Nature of State and Local
Government Concerns, and Statement of
the Extent to Which Those Concerns
Have Been Met
  In general, municipal government
representatives supported the NPDES
approach in today's rule for the
following reasons: it will be uniformly
applied on a nationwide basis; it
provides flexibility to allow
incorporation of State and local
programs; it resolves the problem of
donut holes that cause water quality
impacts in urbanized areas; and it
allows  co-permitting of small regulated
MS4s with those regulated under the
existing storm water program.
  In contrast, State representatives
sought alternative approaches  for State

 preamble, Alternative Permit Option/
 Tenth Amendment.

 3. Summary of the Agency's Position
 Supporting the Need To Issue the
 Regulation

  As discussed more fully in  section I.E.
 above, today's rule is needed because
 uncontrolled storm water discharges
 from areas of urban development and
 construction activity have been shown
 to have negative impacts on receiving
 waters by changing the physical,
 biological, and chemical composition of
 the water, resulting in an unhealthy
 environment for aquatic organisms,
 wildlife, and people. As discussed in
 section II.C., the NPDES approach in
 today's rule is needed to ensure uniform
 application on a nationwide basis, to
 provide flexibility to allow
 incorporation of State and local
 programs, to resolve the problem of
 donut holes that cause water quality
 impacts in urbanized areas, and to allow
 co-permitting of small regulated MS4s
 with those regulated under the existing
 storm water program.
  The draft final rule was transmitted to
OMB on July 6, 1999. Because
transmittal occurred before the
November 2,1999 effective date of
Executive Order 13132, certification
under section 8 of the Executive Order
is not required.

E. Regulatory Flexibility Act (RFA), as
amended by the Small Business
Regulatory Enforcement Fairness Act of
1996 (SBREFA), 5 U.S.C. 601 et seq.
  The RFA generally requires an
Agency to prepare a regulatory
flexibility analysis of any rule subject to
notice and comment rulemaking
requirements under the Administrative
Procedure Act or any other statute
unless the agency certifies  that the rule
will not have a significant economic
impact on a  substantial number of small
entities. Small entities include  small
businesses, small organizations, and
small governmental jurisdictions.
  For purposes of assessing the impact
of today's rule on small entities, small
entity is defined as:  (1) a building
contractor (SIC 15) with up to $17.0
million in annual revenue; (2) a small
governmental jurisdiction that is a
government  of a city, county, town,
school district, or special district with a
population of less than 50,000;  and (3)
a small organization that is any not-for-
profit enterprise which is independently
owned and operated and is not
dominant in its field.
  After considering the economic
impacts of today's final rule on small
entities, I certify that this action will not
have a significant economic impact on
a substantial number of small entities.
  Although this final rule will not  have
a significant economic impact on a
substantial number of small entities,
EPA nonetheless has tried to reduce the
impact of this rule on small entities.
  For purposes of evaluating the
economic impact of this rule on small
governmental jurisdictions, EPA
compared annual compliance costs with
annual government revenues obtained
from the 1992 Census of Governments,
using state-specific estimates of annual
revenue per capita for municipalities in
three population size categories (fewer
than 10,000, 10,000-25,000, and
25,000-50,000).
  In order to estimate the annual
compliance cost for small governmental
jurisdictions, EPA used the mean
variable municipal cost of $8.93 per
household as calculated in a 1998 study
of 121 municipalities conducted by the
national Association of Flood and
Stormwater Management Agencies
(NAFSMA). In addition, EPA used the
estimated fixed administrative costs of
SI,545 per municipality for reporting,

-------
           Federal Register/Vol. 64, No. 235/Wednesday, December 8, 1999/Rules and Regulations    68801
 recordkeeping, and application
 requirements for today's rule.
   In evaluating the economic impact of
 this rule on small governmental
 jurisdictions, EPA determined that
 compliance costs represent more than 1
 percent of estimated revenues for only
 10 percent of small governments and
 more than 3 percent of the revenue for
 0.7 percent of these entities. In both
 absolute and relative terms, EPA does
 not consider this a significant economic
 impact on a substantial number of small
 entities.
   EPA normally uses the "sales test" for
 determining the economic impact on
 small businesses. Under a sales test,
 annual compliance costs are compared
 with the small business's total annual
 sales. However, the direct application of
 the sales test is not suitable in this case,
 because of the uncertainty associated
 with estimating the number of units an
 "average" developer/contractor
 develops or builds in a typical year. For
 this rule, EPA has approximated the
 sales test by estimating compliance
 costs for three sizes of construction sites
 and comparing them with a
 representative sale price for three
 building categories. Although EPA's
 analysis is not exactly a "sales test," it
 is similar to the sales test,  producing
 comparable results.
   For small building contractors, EPA
 estimated administrative compliance
 costs of S870 per site for applying for
 coverage, reporting, record keeping,
 monitoring and preparing  a storm water
 pollution prevention plan. EPA
 estimated compliance costs for
 installing soil and erosion controls as
 ranging from 51,206 to $8,709 per site.
 EPA compliance cost estimates are
 based on 27 theoretical model
 construction sites designed to mimic the
 mostly likely used best management
 practices around the country.
  In evaluating the economic impact on
 small building contractors, EPA divided
 the revised compliance costs per
 construction start by the appropriate
 homes-to-site ratio for each of the three
 sizes of construction sites. The average
 compliance cost per home ranges from
 approximately S450 to S650. EPA
 concluded that compliance costs are
 roughly 0.22 to 0.43 percent of both the
 mean, S181.300, and median, 3151,000,
 sale price of a home.
  The absence of data to specifically
 assess annual compliance costs for
building contractors as a percentage of
 annual sales (i.e., a very direct estimate
 of the impact on potentially affected
small businesses) led EPA  to perform
additional market analysis to examine
the ability of potentially affected firms
to pass along regulatory costs to buyers
 for single-family homes constructed
 subject to today's rule. If the small
 building contractors covered by the rule
 are able to pass on the costs of
 compliance, either completely or
 partially, to their purchasers, then the
 rule's impact on these small business
 entities is significantly reduced. The
 market analysis shows that demand for
 homes is not overly sensitive to  small
 changes in price, therefore builders
 should be able to pass on at least a
 significant fraction of the compliance
 costs to buyers.
   EPA also assessed the effect of the
 building contractors' costs on average
 monthly mortgage rates and on the
 demand for  new homes. Based on that
 screening analysis, EPA concludes that,
 the costs to building contractors, and
 the potential changes in housing prices
 and monthly mortgage payments for
 single-family home buyers, are not
 expected to  have a significant impact on
 the market for single-family houses. In
 both absolute and relative terms, EPA
 does not consider this a significant
 economic impact on a substantial
 number of small entities.
   EPA also certified this rule at
 proposal. Even though the Agency was
 not required to, we convened a Small
 Business Advocacy Review Panel
 ("Panel") in June 1997. A number of
 small entity  representatives had  already
 been actively involved with EPA
 through the  FACA process, and were,
 therefore, broadly knowledgeable about
 the development of the proposed and
 final rules. Prior to convening the Panel,
 EPA consulted with the Small Business
 Administration to identify a group  of
 small entity  representatives to advise
 the Panel. The Agency distributed a
 briefing package describing its
 preliminary  analysis under the RFA to
 the small entity representatives (as well
 as to representatives from OMB and
 SBA) and conducted two telephone
 conference calls and an all-day meeting
 at EPA Headquarters in May of 1997
 with small entity representatives. With
 this preliminary work complete,  in June
 1997, EPA formally convened the
 SBREFA Panel, comprising
 representatives from OMB, SBA, EPA's
 Office of Water and EPA's Small
 Business Advocacy Chair. The Panel
 received written comments from small
 entity representatives based on their
 involvement in the earlier meetings, and
 invited additional comments.
  Consistent with requirements of the
RFA, the Panel evaluated the assembled
 materials and small-entity comments on
 issues related to: (1) a description and
the number of small entities that would
be regulated; (2) a description of the
 projected record keeping, reporting and
 other compliance requirements
 applicable to small entities; (3)
 identification of other Federal rules that
 may duplicate, overlap, or conflict with
 the proposal to the final rule; and (4)
 regulatory alternatives that would
 minimize any significant economic
 impact of the rule on small entities
 while accomplishing the stated
 objectives of the CWA section 402(p)(6).
   On August 7, 1997, the Panel
 provided a Final Report (hereinafter,
 "Report") to the EPA Administrator.' A
 copy of the Report is included in the
 docket for the rule. The Panel
 acknowledged and commended EPA's
 efforts to work with stakeholders,
 including small entities, through the
 FACA process. The SBREFA Panel
 stated that, because of EPA's extensive
 outreach and responsiveness in
 addressing stakeholder concerns,
 commenters during the SBREFA process
 raised fewer concerns than might
 otherwise have been expected. Based on
 the advice and recommendations of the
 Panel, today's rule includes a number of
 provisions designed to minimize  any
 significant impact on small entities. (See
 Appendix 5).

 F. National Technology Transfer And
 Advancement Act
   Section 12(d) of the National
 Technology Transfer and Advancement
 Act of 1995 ("NTTAA"), Public Law
 104-113, section 12(d) (15 U.S.C. 272
 note) directs EPA to use voluntary
 consensus standards in its regulatory
 activities unless to do so would be
 inconsistent with applicable law or
 otherwise impractical. Voluntary
 consensus standards are technical
 standards (e.g., materials specifications,
 test methods, sampling procedures, and
 business practices) that are developed or
 adopted by voluntary consensus
 standard bodies. The NTTAA directs
 EPA to provide Congress,  through OMB,
 explanations when the Agency decides
 not to use available and applicable
 voluntary consensus standards.
  This action does  not mandate the use
 of any particular technical standards,
 although in designing appropriate BMPs
 regulated small MS4s and small
 construction sites are encouraged to use
 any voluntary consensus standards that
 may be applicable and appropriate.
 Because no specific technical standards
 are included in the rule, section 12(d) of
 the NTTAA is not applicable.

 G. Executive Order 13045
  Executive Order 13045:  "Protection of
Children from Environmental Health
Risks and Safety Risks" (62 FR 19885,
April 23, 1997) applies to  any rule that:
 (1) Is determined to be "economically

-------
68802    Federal  Register / Vol.  64,  No. 235/Wednesday,  December  8,  1999/Rules  and Regulations
significant" as defined under E.O.
12866, and (2) concerns an
environmental health or safety risk that
EPA has reason to believe may have a
disproportionate effect on children. If
the regulatory action meets both criteria,
the Agency must evaluate the
environmental health or safety effects of
the planned rule on children, and
explain why the planned regulation is
preferable to other potentially effective
and reasonably feasible alternatives
considered by the Agency.
  This final rule is not subject to E.O.
13045 because it does not concern an
environmental health or safety risk that
may have a disproportionate effect on
children. The rule expands the scope of
the existing NPDES permitting program
to require small municipalities and •
small construction sites to regulate their
storm water discharges. The rule does
not itself, however,  establish standards
or criteria that would be included in
permits for those sources. Such
standards or criteria will be developed
through other actions, for example, in
the establishment of water quality
standards or subsequently in the
issuance of permits themselves. As
such, today's action does not concern an
environmental health or safety risk that
may have a disproportionate effect on
children. To the extent it does address
a risk that may have a disproportionate
effect on children, expanding the scope
of the permitting program will have a
corresponding disproportionate benefit
to children to protect them from such
risk.
H. Executive Order 13084
  Under Executive Order 13084, EPA
may not issue a regulation that is not
required by statute,  that significantly or
uniquely affects the communities of
Indian tribal governments, and that
imposes substantial direct compliance
costs on those communities, unless the
Federal government provides the funds
necessary to pay the direct compliance
costs incurred by the Tribal
                               governments, or EPA consults with
                               those governments. If EPA complies by
                               consulting, Executive Order 13084
                               requires EPA to provide to the Office of
                               Management and Budget, in a separately
                               identified section of the preamble to the
                               rule, a description of the extent of EPA's
                               prior consultation with representatives
                               of affected Tribal governments, a
                               summary of the nature of their concerns,
                               and a statement supporting the need to
                               issue the regulation. In addition,
                               Executive Order 13084 requires EPA to
                               develop an effective process permitting
                               elected officials and other
                               representatives of Indian Tribal
                               governments "to provide meaningful
                               and timely input in the development of
                               regulatory policies on matters that
                               significantly or uniquely affect their
                               communities."
                                 Today's rule does not significantly or
                               uniquely affect the communities of
                               Indian Tribal governments. Even though
                               the Agency is not required to address
                               Tribes under the Regulatory Flexibility
                               Act, EPA used the same revenue test
                               that was used for municipalities to
                               assess the impact of the rule on
                               communities of Tribal governments and
                               determine that they will not be
                               significantly affected. In addition, the
                               rule will not have a unique impact on
                               the communities of Tribal governments
                               because small municipal governments
                               are also covered by this rule and larger
                               municipal governments are already
                               covered by the existing storm water
                               rules. Accordingly, the requirements of
                               section 3(b) of Executive Order 13084
                               do not apply to this rule.
                               I. Congressional Review Act
                                 The Congressional Review Act, 5
                               U.S.C. section 801 et seq.,as added by
                               the Small Business Regulatory
                               Enforcement Fairness Act of 1996,
                               generally provides that before a rule
                               may take effect, the agency
                               promulgating the rule must submit a
                               rule report, which includes a copy  of
                               the rule, to each House of the Congress
and the Comptroller General of the
United States. EPA will submit a report
containing this rule and other required
information to the U.S. Senate, the U.S.
House of Representatives, and the
Comptroller General of the United
States prior to publication of the rule in
the Federal Register. A major rule
cannot take effect until 60 days after it
is published in the Federal Register.
This rule is a "major rule" as defined by
5 U.S.C. 804(2"). This rule will be
effective on February 7, 2000.

    Submission of this No Exposure Certification constitutes notice that the entity identified in Section A does not require permit authorization for its storm water
    discharges associated with industrial activity in the State identified in Section B under EPA's Storm Water Multi-Sector General Permit due to the existence
    ot a condition of no exposure.

    A condition of no exposure exists at an industrial facility when all industrial materials and activities are protected by a storm resistant shelter to prevent
    exposure to rain.  snow, snowmelt, and/or runoff. Industrial materials or activities include, but are not limited to. material handling equipment or activities,
    industrial machinery, raw materials, intermediate products, by-products, final products, or waste products. Material handling activities include the storage.
    loading and unloading, transportation, or conveyance of any raw material, intermediate product, final product or waste product. A storm resistant shelter is
    not required for the following industrial materials and activities:
       - drums, barrels, tanks, and similar containers that are tightly sealed, provided those containers are not deteriorated and do not leak. "Sealed"
         means banded or otherwise secured and without operational taps or valves;
       - adequately maintained vehicles used in material handling; and
       -• final products,  other than products that would be mobilized in storm water discharges (e.g., rack salt).

    A No Exposure Certification must be provided for each facility qualifying for the no exposure exclusion. In addition, the exclusion from NPDES permitting is
    available on a facility-wide basis only, not for individual outfalls. If any industrial activities or materials are or will be exposed to precipitation, the facility is
    not eligible for the no exposure exclusion.

    By signing and submitting this No Exposure Certification form, the entity in Section A is certifying that a condition of no exposure exists at its facility or site,
    and is obligated to comply with the terms and conditions of 40 CFR 122.26(g).

  0.  Certification Statement

     I certily under penalty of law that I  have read and understand the eligibility requirements for claiming a condition of "no exposure" and obtaining an
     exclusion from NPDES storm water permitting.

     I certify under penalty of law that there are no discharges of storm water contaminated by exposure to industrial activities or materials from the industrial
     facility or site identified in this document (except as allowed under 40 CFR I22.26(g)(2)).

     I understand that I am obligated to submit a no exposure certification form once every five years to the NPDES permitting authority and. if requested, to
     the operator of the local municipal separate storm sewer system (MS4) into which the facility discharges (where applicable). I understand that I must
     allow the NPDES permitting authority, or MS4 operator where the discharge is into the local MS4. to perform inspections to confirm the condition of no
     exposure  and to make such inspection reports publicly available upon request. I understand that I must obtain coverage under an NPDES permit prior
     to any point source discharge of storm water from the facility.                                          '

     Additionally, I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a
     system designed to assure that qualified personnel properly gathered and evaluated the information submitted.  Based on my inquiry of the person or
     persons who manage the system, or those persons directly  responsible for gathering the information, the information submitted is to the best of my
     knowledge and belief true, accurate and complete. I am aware that there are significant penalties for submitting false information, including the possibility
     of line and imprisonment for knowing violations.

Instructions for the NO EXPOSURE CERTIFICATION for
     Exclusion from NPDES Storm Water Permitting
    Form Approved
OMB No. 2040-0211
    Who May File a No Exposure Certification

    Federal law at 40 CFR Part 122.26 prohibits point source discharges of
    storm water associated with industrial activity to waters of the U.S. without
    a National Pollutant Discharge Elimination System (NPDES) permit. However,
    NPDES permit coverage is not required for discharges of storm water
    associated with industrial activities identified at 40 CFR 122.26(b)(14)(i)-
    (ix) and (xi) if the discharger can certify that a condition of "no exposure"
    exists at the industrial facility or site.

    Storm water discharges from construction activities identified in 40 CFR
    122.26(b)(14)(x) and (b)(15) are not eligible for the no exposure exclusion.

    Obtaining and Maintaining the No Exposure Exclusion

    This form is used to certify that a condition  of no exposure exists at the
    industrial facility or site described herein. This certification is only applicable
    in jurisdictions where EPA is the NPDES permitting authority and must be
    re-submitted at least once every five years.

    The industrial facility operator must maintain a condition of no exposure at
    its facility or site in order for the no exposure exclusion to remain applicable.
    If conditions change resulting  in the exposure of materials and activities to
    storm water, the facility operator must obtain coverage under an NPDES
    storm water permit immediately.

    Where to File the No Exposure Certification Form

    Mail the completed no exposure certification form to:

      Storm Water No Exposure Certification (4203)
      USEPA
      401 M Street, SW
      Washington, D.C. 20460

    Completing the Form

    You must type or  print, using uppercase letters, in appropriate areas only.
    Enter only one character per space (i.e.. between the marks). Abbreviate
    if necessary to stay within the  number of characters allowed for each item.
    Use one space for breaks between words. One form must be completed
    for each facility or site for which you are seeking to certify a condition of no
    exposure. Additional guidance on completing this form can be accessed
    through EPA's web site at www.epa.gov/owm/sw.  Please make sure you
    have addressed all applicable questions and have made a photocopy for
    your records before sending  the completed form to the above address.

                                                           Latitude and longitude for a facility in decimal form must be converted
                                                           to  degrees  (°). minutes  ('). and seconds  (")  for proper entry on
                                                           the certification, form.  To convert  decimal  latitude or longitude to
                                                           degrees/minutes/seconds, follow the steps in the following example.

                                                           Example: Convert decimal latitude 45.1234567 to degrees (°). minutes
                                                           ('). and seconds (").

                                                            a) The numbers to the left of the decimal point are the degrees:  45°.

                                                            b) To obtain minutes, multiply the first four numbers to the right of the
                                                              decimal point by 0.006: 1234 x 0.006 = 7.404.

                                                            c) The numbers to the left of the decimal point in the result obtained
                                                              in (b) are the minutes: 7'.

                                                            d) To obtain seconds, multiply the remaining three numbers to the
                                                              right of the decimal from the  result  obtained in (b) by 0.06:
                                                              404 x 0.06 = 24.24. Since the numbers to the right of the decimal
                                                              point are not used, the result is 24".

                                                            e) The conversion for 45.1234567 = 45° 7' 24".

                                                        6.  Indicate whether the facility was previously covered under an NPDES
                                                           storm water permit. If so, include the permit number.

                                                        7.  Enter the 4-digit SIC code which identifies the facility's primary activity.
                                                           and second 4-digit SIC code identifying the facility's secondary activity,
                                                           if applicable. SIC codes can be obtained from the Standard Industrial
                                                           Classification Manual, 1987.

                                                        8.  Enter the total size of the site associated with industrial activity in acres.
                                                           Acreage may be determined by dividing square footage by 43,560. as
                                                           demonstrated in the following example.

                                                           Example: Convert 54.450 ft2 to acres

                                                           Divide 54,450 ft2 by 43,560 square feet per acre:
                                                           54,450 «2 * 43,560 ft2/acre = 1.25 acres.

                                                        9. Check "Yes" or "No" as appropriate to indicate  whether you have paved
                                                           or roofed over a formerly exposed, pervious area (i.e., lawn, meadow,
                                                           dirt or gravel road/parking lot) in order to qualify for no exposure. If yes,
                                                           also indicate approximately how much area was paved or roofed over
                                                           and is now impervious area.

Timetables That Are Responsive to Resources
of Small Entities
  NPDES permitting authorities can issue
general permits instead of requiring
individual permits. This flexibility avoids the
high application costs and administrative
burden associated with individual permits.
  NPOES permitting authorities can specify a
time period of up to five  years for small MS4s
to fully develop and implement their
program
  Analytic monitoring is not required.
  After the first permit term and subsequent
permit terms, submittal of a summary report
is only required in years  two and four (Phase
I  municipalities are currently required to
submit a detailed report each year).
  A brief reporting format is  encouraged to
facilitate compiling and analyzing data from
submitted reports. EPA intends to develop a
model form for this purpose.
  NPDES  Permitting Authorities can phase in
permit coverage for small MS4s serving
jurisdictions with a population under 10,000
                              on a schedule consistent with a State
                              watershed permitting approach.

                              Clarifying, Consolidating, or Simplifying
                              Compliance and Reporting Requirements
                                The rule avoids duplication in permit
                              requirements by allowing NPDES permitting
                              authorities to include permit conditions that
                              direct an MS4 to follow the requirements of
                              a qualifying local program rather than the
                              requirements of a minimum measure.
                              Compliance with these programs is
                              considered compliance with the NPDES
                              general permit.
                                The rule allows NPDES permitting
                              authorities to recognize existing
                              responsibilities  among different municipal
                              entities to satisfy obligations for the
                              minimum control measures.
                                A further alternative allows a small MS4 to
                              satisfy its NPDES permit obligations if
                              another governmental entity is already
                              implementing a minimum control measure in
                              the jurisdiction  of the small MS4. The
                              following conditions must be met:
                                1. The other entity is implementing the
                              control measure,
                                2. The particular control measure (or
                              component thereof) is at least as stringent as
                              the corrersponding NPDES permit
                              requirement, and
                                3. The other entity agrees to implement the
                              control measure on your behalf.
                                                     The rule allows a covered small MS4 to
                                                   "piggy-back" on to the storm water
                                                   management program of an adjoining Phase
                                                   I MS4. A small MS4 is waived from the
                                                   application requirements of
                                                   § 122.26(d)(l)(iii), (iv) and (d)(2)(iii)
                                                   [discharge characterization] and may satisfy
                                                   the requirements of § 122.26(d)(l)(v) and
                                                   (d)(2)(iv) [identifying a management plan] by
                                                   referencing the adjoining Phase I MS4's
                                                   storm water management plan.
                                                     The rule accommodates the use of the
                                                   watershed approach through NPDES general
                                                   permits that could be issued on a watershed
                                                   basis. The small MS4 can develop  measures
                                                   that are tailored to meet their watershed
                                                   requirements. The small MS4's storm water
                                                   management program can tie into watershed-
                                                   wide plans.

                                                   Performance Rather Than Design Standards
                                                   for Small Entities
                                                     Small governmental jurisdictions whose
                                                   MS4s are covered by this rule are allowed to
                                                   choose the best management practices
                                                   (BMPs) to be implemented and the
                                                   measurable goals for each of the minimum
                                                   control measures:
                                                     1. Public education and outreach on storm
                                                   water impacts
                                                     2. Public Involvement/Participation
                                                     3. Illicit discharge detection and
                                                   elimination

 68812     Federal Register / Vol.  64, No. 235/Wednesday, December 8,  1999/Rules  and Regulations
   4. Construction site storm water runoff
 control
   5. Post-construction storm water
 management in new development and
 redevelopment
   6. Pollution prevention/good housekeeping
 for municipal operations
   EPA will provide guidance and
 recommend, but not mandate, certain BMPs
 for some of the minimum control measures
 listed above. States can provide guidance to
 supplement or supplant EPA guidance.
   Small MS4s can identify the measurable
 goals for each of the minimum control
 measures listed above. In their reports to the
 NPDES permitting authority, the small MS4s
 must evaluate their progress towards
 achievement of their identified measurable
 goals.

 Waivers for Small Entities From Coverage
   The rule allows permitting authorities to
 waive from coverage MS4s operated by small
 governmental jurisdictions located within an
 urbanized area and serving a population less
 than 1,000 people where the permitting
 authority has determined the MS4 is riot
 contributing substantially to the pollutant
 loadings of an interconnected MS4 and, if the
 MS4 discharges pollutants that have been
 identified as a cause of impairment in the
 receiving water of the MS4 then the
 permitting authority has determined that
 storm water controls are not needed based on
 a TMDL that addresses the pollutants of
 concern.
   The rule allows the permitting authority to
 waive from coverage MS4s serving a
 population under 10,000 where the
 permitting authority has evaluated all waters
 that receive a discharge from the MS4 and
 the permitting authority has  determined that
 storm water controls are not  needed based on
 a TMDL that addresses the pollutants of
 concern  and future discharges do not have
 the potential to result in exceedances of
 water quality standards.

 B. Regulatory Flexibility for Small
 Construction Activities

 Different Compliance, Reporting, or
 Timetables That Are Responsive to Resources
 of Small Entities
  The rule gives NPDES permitting
 authorities discretion not to require the
 submittal of a notice of intent (NOI) for
 coverage under a NPDES general  permit,
 thereby reducing administrative and
 financial burden. All construction sites
 disturbing greater than 5 acres must submit
 an NOI.

 Clarifying, Consolidating, or Simplifying
 Compliance and Reporting Requirements
  The rule avoids duplication by allowing
 the NPDES permitting authority to
 incorporate by reference State, Tribal, or
 local programs under a NPDES general
 permit. Compliance with these programs is
 considered compliance with the NPDES
 general permit.

 Performance Rather Than Design Standards
for Small Entities
  The operator of a covered construction
 activity selects and implement the BMPs
 most appropriate for the construction site
 based on the operator's storm water pollution
 prevention plan.

 Waivers for Small Entities From Coverage
   Waivers could be granted based on the use
 of a rainfall erosivity factor or a
 comprehensive analysis of water quality
 impacts.
   (A) Low rainfall waiver: When the rainfall
 erosivity factor ("R" from Revised Universal
 Soil Loss Equation) is less than 5 during the
 period of construction activity, a permit is
 not required.
   (B) Determination based on Water Quality
 Analysis: The NPDES permitting authority
 can waive from coverage construction
 activities disturbing from 1 acre up to 5 acres
 of land where storm water controls are not
 needed based on:
   1. A TMDL approved or established by
 EPA that addresses the pollutants of concern,
 or
   2. For non-impaired waters, an equivalent
 analysis that  determines that such allocations
 are not needed to protect water quality based
 on consideration of existing in-stream
 concentrations, expected growth in pollutant
 contributions from all sources, and a margin
 of safety.

 C. Regulatory Flexibility for Industrial/
 Commercial Facilities

 Waivers for Small Entities From Coverage
   The rule provides a "no-exposure" waiver
 provision for Phase I industrial/commercial
 facilities. Qualifying facilities seeking this
 provision simply need to complete a self-
 certification form indicating that no
 industrial materials  or activities are exposed
 to rain, snow, snow  melt and/or runoff.

 Appendix 6 of Preamble—
 Governmental Entities Located Fully or
 Partially Within an Urbanized Area

   (This is a reference list only, not a list of
 all operators of small MS4s subject to
 §§ 122.32-122.36. For example, a listed
 governmental entity is only regulated if it
 operates a small MS4 within an "urbanized
 area" boundary as determined by the  Bureau
 of the Census. Furthermore, entities such as
 military bases, large hospitals, prison
 complexes, universities, sewer districts, and
 highway  departments that operate a small
 MS4 within an urbanized area are also
 subject to the permitting regulations but are
 not individually listed here. See
 § 122.26(b)(16) "for the definition of a small
 MS4 and § 122.32{a) for the definition of a
 regulated small MS4.)

Appendix 7 of Preamble —
Governmental Entities (Located Outside

Authority for Potential Designation
Under §123.35(b)(2)
(All listed entities have a population of at
least 10,000 and a population density of at
least 1,000. A listed entity would only be

MS4. See §122.26(b)(16) for the definition of
a small MS4.)
(This list does not include all operators of
small MS4s that may be designated by the
NPDES permitting authority. Operators of

10,000 and densities below 1,000 may also be
designated but examination of them is not
required. Also, entities such as military
bases, large hospitals, prison complexes,
universities, sewer districts, and highway
departments that operate a small MS4 in an
area listed here, or in an area otherwise
designated by the NPDES permitting
authority, may be designated and become

water and that is directly related to
manufacturing, processing or raw
materials storage areas at an industrial
plant. The term does not include
discharges from facilities or activities
excluded from the NPDES program
under this part 122. For the categories
of industries identified in this section,
the term includes, but is not limited to,
storm water discharges from industrial
plant yards; immediate access roads and
rail lines used or traveled by carriers of
raw materials, manufactured products,
waste material, or by-products used or
created by the facility; material handling
sites; refuse sites; sites used for the
application or disposal of process waste
waters (as defined at part 401 of this
chapter); sites used for the storage and
maintenance of material handling
equipment; sites used for residual
treatment, storage, or disposal; shipping
and receiving areas; manufacturing
buildings; storage areas (including tank
farms) for raw materials, and
intermediate and final products; and
areas where industrial activity has taken
place in the past and significant
materials remain and are exposed to
storm water. For the purposes of this
paragraph, material handling activities
include storage, loading and unloading,
transportation, or conveyance of any
raw material, intermediate product,
final product, by-product or waste
product. The term excludes areas
located on plant lands separate from the
plant's industrial activities, such as
office buildings and accompanying
parking lots as long as the drainage from
the excluded areas is not mixed with
storm water drained from the above
described areas.  Industrial facilities
(including industrial facilities that are
federally, State, or municipally owned
or operated that meet the description  of
the facilities listed in paragraphs
(b)(14)(i) through (xi) of this section)
include those facilities designated under
the provisions of paragraph (a)(l)(v) of
this section. The  following categories of
facilities are considered to be engaging
in "industrial activity" for purposes of
paragraph (b)(14):
  (x) Construction activity including
clearing, grading and excavation, except
operations that result in the disturbance
of less than five acres of total land area.
Construction activity also includes the
disturbance of less than five acres of
total land area that is a part of a larger
common plan of development or sale if
the larger common plan will ultimately
disturb five acres or more;
  (xi) Facilities under Standard
Industrial Classifications 20, 21, 22, 23,
2434, 25, 265, 267, 27, 283, 285, 30, 31
(except 311), 323, 34 (except 3441), 35,
36, 37 (except 373), 38, 39, and 4221-
25;
  (l5) Storm water discharge associated
with small construction activity means
the discharge of storm water from:
  (i) Construction activities including
clearing, grading, and excavating that
result in land disturbance of equal to or
greater than one acre and less than  five
acres. Small construction activity also
includes the disturbance of less than
one acre of total land area that is part
of a larger common plan of development
or sale if the larger common plan will
ultimately disturb equal to or greater
than one and less than five acres. Small
construction  activity does not include
routine maintenance that is performed
to maintain the original line and grade,
hydraulic capacity, or original purpose
of the facility. The Director may waive
the otherwise applicable requirements
in a general permit for a storm water
discharge from construction activities
that disturb less than five acres where:
  (A) The value of the rainfall erosivity
factor ("R" in the Revised Universal Soil
Loss Equation) is less than five during
the period of construction activity.  The
rainfall erosivity factor is determined in
accordance with Chapter 2 of
Agriculture Handbook Number  703,
Predicting Soil Erosion by Water: A
Guide to Conservation Planning With
the Revised Universal Soil Loss
Equation (RUBLE), pages 21-64, dated
January 1997. The Director of the
Federal Register approves this
incorporation by reference in
accordance with 5 U.S.C 552(a)  and 1
CFR part 51. Copies may be obtained
from EPA's Water Resource Center, MaiJ
Code RC4100, 401 M St. S.W.,
Washington, DC 20460. A copy is also
available for inspection at the U.S. EPA |
Water Docket, 401 M Street S.W.,
Washington, DC. 20460, or the Office of |
the Federal Register, 800 N. Capitol
Street N.W. Suite 700, Washington, DC. I
An operator must certify to the Director |
that the construction activity will take
place during a period when the value ofl
the rainfall erosivity factor is less than
five; or
  (B) Storm water controls are not
needed based on a "total maximum
daily load" (TMDL) approved or
established by EPA that addresses the
pollutant(s)  of concern or, for non-
impaired waters that do not require
TMDLs, an equivalent analysis that
determines allocations for small
construction sites for the pollutant(s) of j
concern or that determines that such
allocations are not needed to protect
water quality based on consideration of |
existing in-stream concentrations,
expected growth in pollutant
contributions from all sources, and a
margin of safety. For the purpose of this |
paragraph, the pollutant(s) of concern
include sediment or a parameter that
addresses sediment (such as total
suspended solids, turbidity or siltation)
and any other pollutant that has been
identified as a cause of impairment of
any water body that will receive a
discharge from the construction activity.1
The operator must certify to the Director)
that the construction activity will take
place, and storm water discharges will
occur, within the drainage area
addressed by the TMDL or equivalent
analysis.
  (ii) Any other construction activity
designated by the Director, or in States
with approved NPDES programs either
the Director or the EPA Regional
Administrator, based on the potential
for contribution to a violation of a water |
quality standard or for significant
contribution of pollutants to waters of
the United States.

 through (xi) of this section, that is not
 part of a group application as described
 in paragraph (c)(2) of this section or that
 is not authorized by a storm  water
 general permit, a permit application
 made pursuant to paragraph (c) of this
 section must be submitted to the
 Director by October 1, 1992;
   (ii) For any storm water discharge
 associated with industrial activity from
 a facility that is owned or operated by
 a municipality with a population of less
 than 100,000 that is not authorized by
 a general or individual permit, other
 than an airport, powerplant,  or
 uncontrolled sanitary landfill, the
 permit application must be submitted to
 the Director by March 10, 2003.
 *****
  (5) A permit application shall be
 submitted to the Director within 180
 days of notice, unless permission for a
 later date is granted by the Director (see
 § 124.52(c) of this chapter), for:
  (i) A storm water discharge that the
Director, or in States with approved
NPDES programs, either the Director or
the EPA Regional Administrator,
 determines that the discharge
contributes to a violation of a water
quality standard or is a significant
contributor of pollutants to waters of the
United States (see paragraphs (a)(l)(v)
and (b)(15)(ii) of this section);
   (8) For any storm water discharge
 associated with small construction
 activity identified in paragraph (b)(15)(i)
 of this section, see § 122.21(c)(l).
 Discharges from these sources require
 permit authorization by March 10, 2003,
 unless designated for coverage before
 then.
   (9) For any discharge from a regulated
 small MS4, the permit application made
 under § 122.33 must be submitted to the
 Director by:
   (i) March 10, 2003 if designated under
 § 122.32(a)(l) unless your MS4 serves a
 jurisdiction with a population under
 10,000 and the NPDES permitting
 authority has established a phasing
 schedule under § 123.35(d)(3)  (see
 §122.33(c)(l));or
   (ii) Within 180 days of notice, unless
 the NPDES permitting authority grants a
 later date, if designated under
 § 122.32(a)(2) (see § 122.33(c)(2)).
   (f) * * *
   (4) Any person may petition the
 Director for the designation of a large,
 medium, or small municipal separate
 storm sewer system as defined by
 paragraph (b)(4)(iv), (b)(7)(iv), or (b)(16)
 of this section.
   (5) The Director shall make a final
 determination on any petition received
 under this  section within 90 days after
 receiving the petition with the
 exception of petitions to designate a
 small MS4  in which case the Director
 shall make a  final determination on the
petition within 180 days after its
receipt.
   (g) Conditional exclusion for "no
 exposure"  of industrial activities and
materials to storm water. Discharges
composed entirely of storm water are
not storm water discharges associated
with industrial activity if there is  "no
exposure1' of industrial materials and
activities to rain, snow, snowmelt and/
or runoff, and the discharger satisfies
the conditions in paragraphs (g)(l)
through (g)(4) of this section. "No
exposure" means that all industrial
materials and activities are protected by
a storm resistant shelter to prevent
exposure to rain, snow, snowmelt, and/
or runoff. Industrial materials or
activities include, but are not limited to,
material  handling equipment or
activities, industrial machinery, raw
materials, intermediate products, by-
products, final products, or waste

-------
            Federal Register/Vol.  64, No. 235/Wednesday, December 8, 1999/Rules and Regulations     68841
 products. Material handling activities
 include the storage, loading and
 unloading, transportation, or
 conveyance of any raw material,
 intermediate product, final product or
 waste product.
   (1) Qualification. To quality for this
 exclusion, the operator of the discharge
 must:
   (i) Provide a storm resistant shelter to
 protect industrial materials and
 activities from exposure to rain, snow,
 snow melt, and runoff;
   (ii) Complete and sign (according to
 § 122.22) a certification that there are no
 discharges of storm water contaminated
 by exposure to industrial materials and
 activities from the entire facility,  except
 as provided in paragraph (g)(2) of this
 section;
  (iii) Submit the signed certification to
 the NPDES permitting authority once
 every five years;
  (iv) Allow the Director to inspect the
 facility to determine compliance with
 the "no exposure" conditions;
  (v) Allow the Director to make any
 "no exposure" inspection reports
 available to the  public upon request;
 and
  (vi) For facilities that discharge
 through an MS4, upon request, submit
 a copy of the certification of "no
 exposure" to the MS4 operator, as well
 as allow inspection and public reporting
 by the MS4  operator.
  (2) Industrial  materials and activities
 not requiring storm resistant shelter. To
 qualify for this exclusion, storm
 resistant shelter is not required for:
  (i) Drums, barrels, tanks, and similar
 containers that are tightly sealed,
 provided those containers are  not
 deteriorated and do not leak ("Sealed"
 means banded or otherwise secured and
 without operational taps or valves);
  (ii) Adequately maintained vehicles
 used in material handling; and
  (iii) Final  products, other than
 products that would be mobilized in
 storm water discharge (e.g., rock salt).
  (3) Limitations, (i) Storm water
 discharges from construction activities
 identified in paragraphs (b)(14)(x) and
 (b)(15) are not eligible for this
 conditional exclusion.
  (ii) This conditional exclusion from
 the requirement for an NPDES permit is
 available on a facility-wide basis only,
 not for individual outfalls. If a facility
 has some discharges of storm water that
 would otherwise be "no exposure"
 discharges, individual permit
 requirements should be adjusted
accordingly.
  (iii) If circumstances change and
industrial materials or activities become
exposed to rain,  snow, snow melt, and/
or runoff, the conditions for this
 exclusion no longer apply. In such
 cases, the discharge becomes subject to
 enforcement for un-permitted discharge.
 Any conditionally exempt discharger
 who anticipates changes in
 circumstances should apply for and
 obtain permit authorization prior to the
 change of circumstances.
   (iv)  Notwithstanding the provisions of
 this paragraph, the NPDES permitting
 authority retains the authority to require
 permit authorization (and deny this
 exclusion) upon making a determination
 that the discharge causes, has a
 reasonable potential to cause, or
 contributes to an instream excursion
 above  an applicable water quality
 standard, including designated uses.
   (4) Certification. The no exposure
 certification must require the
 submission of the following
 information, at a minimum, to aid the
 NPDES permitting authority in
 determining if the facility qualifies for
 the no exposure exclusion:
   (i) The legal name, address and phone
 number of the discharger (see
 §122.21(b));
   (ii) The facility name and address, the
 county name and the latitude and
 longitude where the facility is located;
   (iii) The certification must indicate
 that none of the following materials or
 activities are, or will be in the
 foreseeable future, exposed to
 precipitation:
   (A) Using, storing or cleaning
 industrial machinery or equipment, and
 areas where residuals from using,
 storing or cleaning industrial machinery
 or equipment remain and are exposed to
 storm water;
   (B) Materials or residuals on the
 ground or in storm water inlets from
 spills/leaks;
   (C) Materials or products from past
 industrial activity;
   (D) Material handling equipment
 (except adequately maintained
 vehicles);
   (E) Materials or products during
 loading/unloading or transporting
 activities;
  (F) Materials or products stored
 outdoors (except final products
 intended for outside use, e.g., new cars,
where exposure to storm water does not
result in the discharge of pollutants);
  (G) Materials contained in open,
 deteriorated or leaking storage drums,
barrels, tanks, and similar containers;
  (H) Materials or products handled/
stored on roads or railways owned or
maintained by the discharger;
  (I) Waste material (except waste in
covered, non-leaking containers, e.g.,
dumpsters);
   (J) Application or disposal of process
 wastewater (unless otherwise
 permitted); and
   (K) Particulate matter or visible
 deposits of residuals from roof stacks/
 vents not otherwise regulated, i.e.,
 under an air quality control permit, and
 evident in the storm water outflow;
   (iv) All "no exposure" certifications
 must include the following certification
 statement, and be signed in accordance
 with the signatory requirements of
 § 122.22: "I certify under penalty of law
 that I have read and understand the
 eligibility requirements for claiming a
 condition of "no exposure" and
 obtaining an exclusion from NPDES
 storm water permitting; and that there
 are no discharges of storm water
 contaminated by exposure to industrial
 activities or materials from the
 industrial facility identified in this
 document (except as allowed under
 paragraph (g)(2)) of this section. I
 understand that I am obligated to submit
 a no exposure certification form once
 every five years to the NPDES
 permitting authority and, if requested,
 to the operator of the local MS4 into
 which this facility discharges (where
 applicable). I understand that I must
 allow the NPDES permitting authority,
 or MS4 operator where the discharge is
 into the local MS4, to perform
 inspections to confirm the condition of
 no exposure and to make such
 inspection reports publicly available
 upon request. I understand that I must
 obtain  coverage under an NPDES permit
 prior to any point source discharge of
 storm water from the facility. I certify
 under penalty of law that this document
 and all attachments were prepared
 under my direction or supervision in
 accordance with a system designed to
 assure that qualified personnel properly
 gathered and evaluated the information
 submitted. Based upon my inquiry of
 the person or persons who manage the
 system, or those persons directly
 involved in gathering the information,
 the information submitted is to the best
 of my knowledge and belief true,
 accurate and complete. I am  aware there
 are significant penalties for submitting
 false information, including the
possibility of fine and imprisonment for
knowing violations."
  4. Revise § 122.28(b)(2)(v) to read as
follows:

 separate storm sewer systems, primary
 industrial facilities, and storm water
 discharges associated with industrial
 activity, may, at the discretion of the  '
 Director, be authorized to discharge
 under a general permit without
 submitting a notice of intent where the
 Director finds that a notice of intent
 requirement would be inappropriate. In
 making such a finding, the Director
 shall consider: the type of discharge; the
 expected nature of the discharge; the
 potential for toxic and conventional
 pollutants in the discharges; the
 expected volume  of the discharges;
 other means of identifying discharges
 covered by the permit; and the
 estimated number of discharges to be
 covered by the permit. The Director
 shall provide in the public notice of the
 general permit the reasons for not
 requiring a notice of intent.
 *****
  5. Add §§ 122.30 through 122.37 to
 subpart B to read as follows:

 § 122.30 What are the objectives of the
 storm water regulations for small MS4s?
  (a) Sections 122.30 through 122.37 are
 written in a "readable regulation"
 format that includes both rule
 requirements and EPA guidance that is
 not legally binding. EPA has clearly
 distinguished its recommended
 guidance from the rule requirements by
 putting the guidance in a separate
 paragraph headed by the word
 "guidance".
  {b) Under the statutory mandate in
 section 402(p)(6) of the Clean Water Act,
 the purpose of this portion of the storm
 water program is to designate additional
 sources that need  to be regulated to
 protect water quality and to establish a
 comprehensive storm water program to
 regulate these sources. (Because the
 storm water program is part of the
 National Pollutant Discharge
Elimination System (NPDES) Program,
 you should also refer to § 122.1 which
 addresses the broader purpose of the
 NPDES program.)
  (c) Storm water runoff continues to
 harm the nation's waters. Runoff from
 lands modified by human activities can
 harm surface water resources in several
 ways including by changing natural
hydrologic patterns and by elevating
pollutant concentrations and loadings.
 Storm water runoff may contain or
mobilize high levels of contaminants,
such as sediment, suspended solids,
nutrients, heavy metals, pathogens,
toxins, oxygen-demanding substances,
and floatables.
  (d) EPA strongly encourages
partnerships and the watershed
approach as the management framework
for efficiently, effectively, and
consistently protecting and restoring
aquatic ecosystems and protecting
public health.

§ 122.31  As a Tribe, what is my role under
the NPDES storm water program?
  As a Tribe you may:
  (a) Be authorized to operate the
NPDES program including the storm
water program, after EPA  determines
that you are eligible for treatment in the
same manner as a State under §§ 123.31
through 123.34 of this chapter. (If you
do not have an authorized NPDES
program, EPA implements the program
for discharges on your reservation as
well as otiier Indian country, generally.);
  (b) Be classified as an owner of a
regulated small MS4, as defined in
§ 122.32. (Designation of your Tribe as
an owner of a small MS4 for purposes
of this part is an approach that is
consistent with EPA's 1984 Indian
Policy of operating on a government-to-
government basis with EPA looking to
Tribes as the lead governmental
authorities to address environmental
issues on their reservations as
appropriate. If you operate a separate
storm sewer system that meets the
definition of a regulated small MS4, you
are subject to the requirements under
§§ 122.33 through 122.35. If you are not
designated as a regulated small MS4,
you may ask EPA to designate you as
such for the purposes of this part.); or
  (c) Be a discharger of storm water
associated with industrial activity or
small construction activity under
§§ 122.26(b)(14) or (b)(15), in which
case you must meet the applicable
requirements. Within Indian country,
the NPDES permitting authority is
generally EPA, unless you are
authorized to administer the NPDES
program.

§ 122.32 As an operator of a small MS4,
am I regulated under the NPDES storm
water program?
  (a) Unless you qualify for a waiver
under paragraph (c) of this section, you
are regulated if you operate a small
MS4, including but not limited to
systems operated by federal, State,
Tribal, and local governments,
including State departments of
transportation; and:
  (1) Your small MS4 is located in an
urbanized area as determined by the
latest Decennial Census by the Bureau
of the Census. (If your small MS4 is not
located entirely within an urbanized
area, only the portion that is within the
urbanized area is regulated); or
  (2) You are designated by the NPDES
permitting authority, including where
the designation is pursuant to
§§ 123.35(b)(3) and (b)(4) of this chapter,
or is based upon a petition under
§122.26(f).
  (b) You may be the subject of a
petition to the NPDES permitting
authority to require an NPDES permit
for your discharge of storm water. If the
NPDES permitting authority determines
that you need a permit, you are required
to comply with §§ 122.33 through
122.35.
  (c) The NPDES permitting authority
may waive the requirements otherwise
applicable to you if you meet the criteria
of paragraph  (d) or (e)  of this section. If
you receive a waiver under this section,
you may subsequently be required to
seek coverage under an NPDES permit
in accordance with § 122.33(a) if
circumstances change. (See also
§ 123.35(b) of this chapter.)
  (d) The NPDES permitting authority
may waive permit coverage if your MS4
serves a population of less than 1,000
within the urbanized area and you meet
the following criteria:
  (1) Your system is not contributing
substantially  to the pollutant loadings of
a physically interconnected MS4 that is
regulated by the NPDES storm water
program (see  § 123.35(b)(4) of this
chapter); and
  (2) If you discharge any pollutant(s)
that have been identified  as a cause of
impairment of any water body to which
you discharge, storm water controls are
not needed based on wasteload
allocations that are part of an EPA
approved or established "total
maximum daily load"  (TMDL)  that
addresses the pollutant(s) of concern.
  (e) The NPDES permitting authority
may waive permit coverage if your MS4
serves a population under 10,000 and
you meet the  following criteria:
  (1) The permitting authority has
evaluated all  waters of the U.S.,
including small streams, tributaries,
lakes, and ponds, that  receive a
discharge from your MS4;
  (2) For all such waters,  the permitting
authority has determined that storm
water controls are not needed based on
wasteload allocations that are part of an
EPA approved or established TMDL that
addresses the pollutant(s) of concern or,
if a TMDL has not been developed or
approved, an  equivalent analysis that
determines sources and allocations  for
the pollutant(s) of concern;
  (3) For the purpose of this paragraph
(e), the pollutant(s) of concern include
biochemical oxygen demand (BOD),
sediment or .a parameter that addresses
sediment (such as total suspended
solids, turbidity or siltation), pathogens,
oil and grease, and any pollutant that
has been identified as  a cause of
impairment of any water body that will
receive a discharge from your MS4; and

-------
           Federal Register/Vol.  64,  No. 235/Wednesday, December  8,  1999/Rules and Regulations    688431
   (4) The permitting authority has
 determined that future discharges from
 your MS4 do not have the potential to
 result in exceedances of water quality •
 standards, including impairment of
 designated uses, or other significant
 water quality impacts, including habitat
 and biological impacts.

 § 122.33  If I am an operator of a regulated
 small MS4, how do I apply for an NPDES
 permit and when do I have to apply?
   (a) If you operate a regulated small
 MS4 under § 122.32, you must seek
 coverage under a NPDES permit issued
 by your NPDES permitting authority. If
 you are located in an NPDES authorized
 State, Tribe, or Territory, then that State,
 Tribe, or Territory is your NPDES
 permitting authority. Otherwise, your
 NPDES permitting authority is the EPA
 Regional Office.
   (b) You must seek authorization to
 discharge under a general or individual
 NPDES permit, as follows:
   (1) If your NPDES permitting
 authority has issued a general permit
 applicable to your discharge and you are
 seeking coverage under the general
 permit, you must submit a Notice of
 Intent (NOI) that includes the
 information on your best management
 practices and measurable goals required
 by § 122.34(d). You may file your own
 NOI, or you and other municipalities or
 governmental entities may jointly
 submit an NOI. If you want to share
 responsibilities for meeting the
 minimum measures with other
 municipalities or governmental entities.
 you must submit an NOI that describes
 which minimum measures you will
 implement and identify the entities that
 will implement the other minimum
 measures within the area served by your
 MS4. The general permit will  explain
 any other steps necessary to obtain
 permit authorization.
  (2)(i) If you are seeking authorization
 to discharge under an individual permit
 and wish to implement a program under
 § 122.34, you must submit an
 application to your NPDES permitting
 authority that includes the information
 required under §§ 122.21 (f) and
 122.34(d), an estimate of square mileage
 served by your small MS4, and any
 additional information that your NPDES
 permitting authority requests. A storm
 sewer map that satisfies the requirement
 of § 122.34(b)(3)(i) will satisfy the map
requirement in § 122.21(f)(7).
  (ii) If you are seeking authorization to
 discharge under an individual permit
 and wish to implement a program that
 is different from the program under
 § 122.34, you will need to comply with
the permit application requirements of
§ 122.26(d). You must submit both Parts
 of the application requirements in
 §§ 122.26(d)(l) and (2) by March 10,
 2003. You do not need to submit the
 information required by
 §§ 122.26(d)(l)(ii) and (d)(2) regarding
 your legal authority, unless you intend
 for the permit writer to take such
 information into account when
 developing your other permit
 conditions.
   (iii) If allowed by your NPDES
 permitting authority, you and another
 regulated entity may jointly apply under
 either paragraph (b)(2}(i) or (b)(2)(ii) of
 this  section to be co-permittees under an
 individual permit.
   (3) If your small MS4 is in the same
 urbanized area as a medium or large
 MS4 with an NPDES storm water permit
 and  that other MS4 is willing to have
 you  participate in its storm water
 program, you and the other MS4 may
 jointly seek a modification of the other
 MS4 permit to include you as a limited
 co-permittee. As a limited co-permittee,
 you  will be responsible for compliance
 with the permit's conditions applicable
 to your jurisdiction. If you  choose this
 option you will need to comply with the
 permit application requirements of
 § 122.26, rather than the requirements of
 § 122.34. You do not need to comply
 with the specific application
 requirements of § 122.26(d)(l)(iii) and
 (iv) and (d)(2)(iii) (discharge
 characterization). You may satisfy the
 requirements in § 122.26 (d)(l)(v) and
 (d)(2)(iv) (identification of a
 management program) by referring to
 the other MS4's storm water
 management program.
  (4) Guidance: In referencing an MS4's
 storm water management program, you
 should briefly describe how the existing
 plan will address discharges from your
 small MS4 or would need to be
 supplemented in order to adequately
 address your discharges.  You should
 also  explain your role in coordinating
 storm water pollutant control activities
 in your MS4, and detail the resources
 available to you to accomplish the plan.
  (c) If you operate a regulated small
 MS4:
  (1) Designated under § 122.32(a)(l),
 you must apply for coverage under an
 NPDES permit, or apply for a
 modification of an existing NPDES
 permit under paragraph (b)(3) of this
 section by March 10, 2003, unless your
 MS4 serves a jurisdiction with a
population under 10,000 and the
NPDES permitting authority has
 established a phasing schedule under
 § 123.35(d)(3) of this chapter.
  (2) Designated under § 122.32(a)(2),
you must apply for coverage under an
NPDES permit, or apply for a
modification of an existing NPDES
 permit under paragraph (b)(3) of this
 section, within 180 days of notice,
 unless the NPDES permitting authority
 grants a later date.

 § 122.34  As an operator of a regulated
 small MS4, what will my NPDES MS4 storm
 water permit require?
   (a) Your NPDES MS4 permit will
 require at a minimum that you develop,
 implement, and enforce a storm water
 management program designed to
 reduce the discharge of pollutants from
 your MS4 to the maximum extent
 practicable (MEP), to protect water
 quality, and to satisfy the appropriate
 water quality requirements of the Clean
 Water Act. Your storm water
 management program must include the
 .minimum control measures described in |
 paragraph (b) of this section unless you
 apply for a permit under § 122.26(d).
 For purposes of this section, narrative
 effluent limitations requiring
 implementation of best management
 practices (BMPs) are generally the most
 appropriate form of effluent limitations
 when designed to satisfy technology
 requirements (including reductions of
 pollutants to the maximum extent
 practicable) and to protect  water quality. I
 Implementation of best management
 practices consistent with the provisions
 of the storm water management program
 required pursuant to this section and
 the provisions of the permit required
 pursuant to § 122.33 constitutes
 compliance with the standard of
 reducing pollutants to the "maximum
 extent practicable." Your NPDES
 permitting authority will specify a time
 period of up to 5 years from the date of
 permit issuance for you to develop and
 implement your program.
  (b) Minimum control measures—(1)
 Public education and outreach on storm
 water impacts, (i) You must implement
 a public education program to distribute
 educational materials to the community
 or conduct equivalent outreach
activities about the impacts of storm
water discharges on water bodies and
the steps that the public can take to
reduce pollutants in storm  water runoff.
  (ii) Guidance: You may use storm
water educational materials provided by
your State, Tribe, EPA, environmental,
public interest or trade organizations, or
other MS4s. The public education
program should inform individuals and
households about the steps they  can
take to reduce storm water pollution,
such as ensuring proper septic system
maintenance, ensuring the  proper use
and disposal of landscape and garden
chemicals including fertilizers and
pesticides, protecting and restoring
riparian vegetation, and properly
disposing of used motor oil or

-------
  68844   Federal Register/Vol. 64, No.  235/Wednesday, December 8,  1999/Rules and Regulations
  household hazardous wastes. EPA
  recommends that the program inform
  individuals and groups how to become
  involved in local stream and beach
  restoration activities as well as activities
  that are coordinated by youth service
  and conservation corps or other citizen
  groups. EPA recommends that the
  public education program be tailored,
  using a mix of locally appropriate
  strategies, to target specific audiences
  and communities. Examples of
  strategies include distributing brochures
  or fact sheets, sponsoring speaking
  engagements before community groups,
  providing public service
  announcements, implementing
  educational programs targeted  at school
  age children, and conducting
  community-based projects such as storm
  drain stenciling, and watershed and
  beach cleanups. In addition, EPA
  recommends that some of the materials
  or outreach programs be directed toward
  targeted groups of commercial,
  industrial, and institutional entities
  likely to have significant storm water
  impacts. For example, providing
  information to restaurants on the impact
 of grease clogging storm drains and to
 garages on the  impact of oil discharges.
 You are encouraged to tailor your
 outreach program to address the
 viewpoints and concerns of all
 communities, particularly minority and
 disadvantaged communities, as well as
 any special concerns relating to
 children.
   (2) Public involvement/participation.
 (i] You must, at a minimum, comply
 with State, Tribal and local public
 notice requirements when
 implementing a public involvement/
 participation program.
   (ii) Guidance: EPA recommends that
 the public be included in developing,
 implementing,  and reviewing your
 storm water management program and
 that the public  participation process
 should make efforts to reach out and
 engage all economic and ethnic groups.
 Opportunities for members of the  public
 to participate in program development
 and implementation include serving as
 citizen representatives on a local storm
 water management panel, attending
 public hearings, working as citizen
 volunteers to educate other individuals
 about the program, assisting in program
 coordination with other pre-existing
programs, or participating in volunteer
monitoring efforts, (Citizens should
obtain approval where necessary for
lawful access to monitoring sites.)
  (3) Illicit discharge detection and
elimination, (i) You must develop,
implement and  enforce a program to
detect and eliminate illicit discharges
  (as defined at § 122.26(b)(2)) into your
  small MS4.
    (ii) You must:
    (A) Develop, if not already completed,
  a storm sewer system map, showing the
  location of all outfalls and the names
  and location of all waters of the United
  States that receive discharges from those
  outfalls;
    (B) To the extent allowable under
  State, Tribal or local law, effectively
  prohibit, through ordinance, or other
  regulatory mechanism, non-storm water
  discharges into your storm sewer system
  and implement appropriate enforcement
  procedures and actions;
   (C) Develop and implement a plan to
  detect and address non-storm water
  discharges, including illegal dumping,
  to your system; and
   (D) Inform public employees,
  businesses, and the general public of
  hazards associated with illegal
  discharges and improper disposal of
 waste.
   (iii) You need address the following
 categories of non-storm water discharges
 or flows (i.e.,  illicit discharges) only if
 you identify them as significant
 contributors of pollutants to your small
 MS4: water line flushing, landscape
 irrigation, diverted stream flows, rising
 ground waters, uncontaminated ground
 water infiltration (as defined at 40 CFR
 35.2005(20)), uncontaminated pumped
 ground water, discharges from potable
 water sources, foundation drains, air
 conditioning condensation, irrigation
 water, springs, water from crawl space
 pumps, footing drains, lawn watering,
 individual residential car washing,
 flows from riparian habitats and
 wetlands, dechlorinated swimming pool
 discharges, and street wash water
 (discharges or flows from fire fighting
 activities are excluded from the effective
 prohibition against non-storm water and
 need only be addressed where they are
 identified as significant sources of
 pollutants to waters of the United
 States).
   (iv) Guidance: EPA recommends that
 the plan to detect and address illicit
 discharges include the following four
 components: procedures for locating
 priority areas likely to have illicit
 discharges; procedures for tracing the
 source of an illicit discharge; procedures
 for removing the source of the
 discharge; and procedures for program
 evaluation and assessment. EPA
 recommends visually screening outfalls
 during dry weather and conducting field
 tests of selected pollutants as part of the
 procedures for locating priority areas.
 Illicit discharge education actions may
include storm drain stenciling, a
program to promote, publicize, and
facilitate public reporting of illicit
  connections or discharges, and
  distribution of outreach materials.
    (4) Construction site storm water
  runoff control, (i) You must develop,
  implement, and enforce a program to
  reduce pollutants in any storm water
  runoff to your small MS4 from
  construction activities that result in a
  land disturbance of greater than or equal
  to one acre. Reduction of storm water
  discharges from construction activity
  disturbing less than one acre must be
  included in your program if that
  construction activity is part of a larger
  common plan  of development or sale
  that would disturb one acre or more. If
  the NPDES permitting authority waives
  requirements for storm water discharges
  associated with small construction
  activity in accordance with
  § 122.26(b)(15)(i), you are not required
  to develop, implement, and/or enforce a
  program to reduce pollutant discharges
  from such sites.
   (ii) Your program must include the
  development and implementation of, at
 a minimum:
   (A) An ordinance or other regulatory
 mechanism to require erosion and
 sediment controls, as well as sanctions
 to ensure compliance, to the extent
 allowable under  State, Tribal, or local
 law;
   (B) Requirements for construction site
 operators to implement appropriate
 erosion and sediment control best
 management practices;
   (C) Requirements for construction site
 operators to control waste such as
 discarded building materials, concrete
 truck washout, chemicals, litter, and
 sanitary waste at  the construction site
 that may cause adverse impacts to water
 quality;
   (D) Procedures for site plan review
 which incorporate consideration of
 potential water quality impacts;
   (E) Procedures  for receipt and
 consideration of information submitted
 by the public, and
   (F) Procedures for site inspection and
 enforcement of control measures.
   (iii) Guidance: Examples of sanctions
 to ensure compliance include non-
 monetary penalties, fines, bonding
 requirements and/or permit denials for
 non-compliance. EPA recommends that
 procedures for site plan review include
 the review  of individual pre-
 construction site plans to ensure
 consistency with local sediment and
 erosion control  requirements.
Procedures for site inspections and
 enforcement of control measures could
 include steps to identify priority sites
for inspection and enforcement based
on the nature of the construction
activity, topography, and the
characteristics of soils and receiving

-------
           Federal Register/Vol. 64, No.  235/Wednesday,  December 8, 1999/RuIes and  Regulations    68845J
water quality. You are encouraged to
provide appropriate educational and
training measures for construction site
operators. You may wish to require a  '
storm water pollution prevention plan
for construction sites within your
jurisdiction that discharge into your
system. See § 122.44(s) (NPDES
permitting authorities' option to
incorporate qualifying State, Tribal and
local erosion and sediment control
programs into NPDES permits for storm
water discharges from construction
sites). Also see § 122.35(b) (The NPDES
permitting authority may recognize that
another government entity, including
the permitting authority, may be
responsible for implementing one or
more of the minimum measures on your
behalf.)
  (5) Post-construction storm water
management in new development and
redevelopment.
  (5) You must develop, implement, and
enforce a program to address storm
water runoff from new development and
redevelopment projects that disturb
greater than or equal to one acre,
including projects less than one acre
that are part of a larger common plan of
development  or sale, that discharge into
your small MS4. Your program must
ensure that controls are in place that
would prevent or minimize water
quality impacts.
  (ii) You must:
  (A) Develop and implement strategies
which include a combination of
structural and/or non-structural best
management practices (BMPs)
appropriate for your community;
  (B) Use an ordinance or other
regulatory mechanism to address post-
construction runoff from new
development and redevelopment
projects to the extent allowable under
State, Tribal or local law; and
  (C) Ensure adequate long-term
operation and maintenance of BMPs.
  (iii) Guidance: If water quality
impacts are considered from the
beginning stages of a project, new
development and potentially
redevelopment provide more
opportunities for water quality
protection. EPA recommends that the
BMPs chosen: be appropriate for the
local community; minimize water
quality impacts; and attempt to
maintain pre-development runoff
conditions. In choosing appropriate
BMPs, EPA encourages you to
participate in locally-based watershed
planning efforts which attempt to
involve a diverse group of stakeholders
including interested citizens. When
developing a program that is  consistent
with this measure's intent, EPA
recommends that you adopt a planning
process that identifies the
municipality's program goals (e.g.,
minimize water quality impacts
resulting from post-construction runoff
from new development and
redevelopment), implementation
strategies (e.g., adopt a combination of
structural and/or non-structural BMPs),
operation and maintenance policies and
procedures, and enforcement
procedures. In developing your
program, you should consider assessing
existing ordinances, policies, programs
and studies that address storm water
runoff quality. In addition to assessing
these existing documents and programs,
you should provide opportunities to the
public to participate in the development
of the program.  Non-structural BMPs are
preventative actions that involve
management and source controls such
as: policies and  ordinances that provide
requirements and standards to direct
growth to identified areas, protect
sensitive areas such as wetlands and
riparian areas, maintain and/or increase
open space (including a dedicated
funding source for open space
acquisition), provide buffers along
sensitive water bodies, minimize
impervious surfaces, and minimize
disturbance of soils and vegetation;
policies or ordinances that encourage
infill development  in higher density
urban areas, and areas with existing
infrastructure; education programs for
developers  and  the public about project
designs that minimize water quality
impacts; and measures such as
minimization of percent impervious
area after development and
minimization of directly connected
impervious areas. Structural BMPs
include: storage practices such as wet
ponds and extended-detention outlet
structures; filtration practices such as
grassed swales,  sand filters and filter
strips; and infiltration practices such as
infiltration  basins and infiltration
trenches. EPA recommends that you
ensure the appropriate implementation
of the structural BMPs by considering
some or all of the following: pre-
construction review of BMP designs;
inspections during  construction to
verify BMPs are built as designed; post-
construction inspection and
maintenance of BMPs; and penalty
provisions for the noncompliance with
design, construction or operation and
maintenance. Storm water technologies
are constantly being improved, and  EPA
recommends that your requirements be
responsive  to these changes,
developments or improvements in
control technologies.
  (6) Pollution prevention/good
housekeeping for municipal operations.
(i) You must develop and implement an |
operation and maintenance program
that includes a training component and
has the ultimate goal of preventing or
reducing pollutant runoff from
municipal operations. Using training
materials that are available from EPA,
your State, Tribe, or other organizations,]
your program must include employee
training to prevent and reduce storm
water pollution from activities such as
park and open space maintenance, fleet
and building maintenance, new
construction and land disturbances, and|
storm water system maintenance.
  (ii) Guidance: EPA recommends that,
at a minimum, you consider the
following in developing your program:
maintenance activities, maintenance
schedules, and long-term inspection
procedures for structural and non-
structural storm water controls to
reduce floatables and other pollutants
discharged from your separate storm
sewers; controls for reducing or
eliminating the discharge of pollutants
from streets, roads, highways, municipal]
parking lots, maintenance and storage
yards, fleet or maintenance shops with
outdoor storage areas, salt/sand storage
locations and snow disposal areas
operated by you, and waste transfer
stations; procedures for properly
disposing of waste removed from the
separate storm sewers and areas listed
above (such as dredge spoil,
accumulated sediments,  floatables, and
other debris); and ways to ensure that
new  flood management projects assess
the impacts on water quality and
examine existing projects for
incorporating additional water quality
protection devices or practices.
Operation and maintenance should be
an integral component of all storm water I
management programs. This measure is
intended to improve the  efficiency of
these programs and require new
programs where necessary. Properly
developed and implemented operation
and maintenance programs reduce the
risk of water quality problems.
  (c) If an existing qualifying local
program requires you to implement one
or more of the minimum control
measures of paragraph (b) of this
section, the'NPDES permitting authority
may  include conditions in your NPDES
permit that direct you to follow that
qualifying program's requirements
rather than the requirements of
paragraph (b) of this section. A
qualifying local program is a local, State
or Tribal municipal storm water
management program that imposes, at a
minimum, the relevant requirements of
paragraph (b) of this section.
  (d)(l) In your permit application
(either a notice of intent for coverage

-------
 68846    Federal Register/Vol. 64. No.  235/Wednesday, December  8, 1999/Rules and Regulations
  under a general permit or an individual
  permit application), you must identify
  and submit to your NPDES permitting
  authority the following information:  •
   (i) The best management practices
  (BMPs) that you or another entity will
  implement for each of the storm water
  minimum control measures at
  paragraphs (b)(l) through (b)(6) of this
  section;
   (ii) The measurable goals for each of
  the BMPs including, as appropriate, the
  months and years in which you will
  undertake required actions, including
  interim milestones and the frequency of
  the action; and
   (iii) The person or persons
 responsible for implementing or
 coordinating your storm water
 management program.
   (2) If you obtain coverage under a
 general permit, you are not required to
 meet any measurable goal(s) identified
 in your notice of intent in order to
 demonstrate compliance with the
 minimum control measures in
 paragraphs (b)(3) through (b)(6) of this
 section unless, prior to submitting your
 NOI, EPA or your State or Tribe has
 provided or issued a menu of BMPs that
 addresses each such minimum measure.
 Even if no regulatory authority issues
 the menu of BMPs, however, you still
 must comply with other requirements of
 the general permit, including good faith
 implementation of BMPs designed to
 comply with the minimum measures.
   (3) Guidance: Either EPA or your State
 or Tribal permitting authority will
 provide a menu of BMPs. You may
 choose BMPs from the menu or select
 others that satisfy the minimum control
 measures.
   (e)(l) You must comply with any
 more stringent effluent limitations in
 your permit, including permit
 requirements that modify, or are in
 addition to, the minimum control
 measures based on an approved total
 maximum daily load (TMDL) or
 equivalent analysis. The permitting
 authority may include such more
 stringent limitations based on a TMDL
 or equivalent analysis that determines
 such limitations are needed to protect
 water quality.
  (2) Guidance: EPA strongly
 recommends that until the evaluation of
 the storm water program in § 122.37, no
 additional requirements beyond the
 minimum control measures be imposed
 on regulated small MS4s without the
 agreement of the operator of the affected
 small MS4, except where an approved
TMDL or equivalent analysis provides
adequate information to develop more
specific measures to protect water
quality.
   (f) You must comply with other
 applicable NPDES permit requirements,
 standards and conditions established in
 the individual or general permit,
 developed consistent with the
 provisions of §§ 122.41 through 122.49,
 as appropriate.
   (g) Evaluation and assessment— (1)
 Evaluation. You must evaluate program
 compliance, the appropriateness of your
 identified best management practices,
 and progress towards achieving your
 identified measurable goals.
   Note to Paragraph (g)(l): The NPDES
 permitting authority may determine
 monitoring requirements for you in
 accordance with State/Tribal monitoring
 plans appropriate to your watershed.
 Participation in a group monitoring program
 is encouraged.

   (2) Recordkeeping. You must keep
 records required by the NPDES permit
 for at least 3 years. You must submit
 your records to the NPDES permitting
 authority only when specifically asked
 to do so. You must make your records,
 including a description of your storm
 water management program, available to
 the public at reasonable times during
 regular business hours (see § 122.7 for
 confidentiality provision). (You may
 assess a reasonable charge for copying.
 You may require a member of the public
 to provide advance notice.)
   (3) Reporting.  Unless you are relying
 on another entity to satisfy your NPDES
 permit obligations under § 122.35(a),
 you must submit annual reports to the
 NPDES permitting authority for your
 first permit term. For subsequent permit
 terms, you must submit reports in year
 two and four unless the NPDES
 permitting authority requires more
 frequent reports. Your report must
 include:
  (i) The status of compliance with
 permit conditions, an assessment of the
 appropriateness of your identified best
 management practices and progress
 towards achieving your identified
 measurable goals for each of the
 minimum control measures;
  (ii) Results of information collected
 and analyzed, including monitoring
 data, if any, during the reporting period;
  (iii) A summary of the storm water
 activities you plan to undertake during
 the next reporting cycle;
  (iv) A change in any identified best
 management practices or measurable
 goals for any of the minimum control
 measures; and
  (v) Notice that  you are relying on
 another governmental entity to satisfy
some of your permit obligations (if
applicable).
 § 122.35  As an operator of a regulated
 small MS4, may I share the responsibility to
 implement the minimum control measures
 with other entities?

   (a) You may rely on another entity to
 satisfy your NPDES permit obligations
 to implement a minimum control
 measure if:
   (1) The other entity, in fact,
 implements the control measure;
   (2) The particular control measure, or
 component thereof, is at least as
 stringent as the corresponding NPDES
 permit requirement; and
   (3) The other entity agrees to
 implement the control measure on your
 behalf. In the reports you must submit
 under § 122.34(g)(3), you must also
 specify that you rely on another entity
 to satisfy some of your permit
 obligations. If you are relying on another
 governmental entity regulated under
 section 122 to satisfy all of your permit
 obligations, including your obligation to
 file periodic reports required by
 § 122.34(g)(3), you must note that fact in
 your NOI, but you are not required to
 file the periodic reports. You remain
 responsible for compliance with your
 permit obligations if the other entity
 fails to implement the control measure
 (or component thereof). Therefore, EPA
 encourages you to enter into a legally
 binding agreement with that entity if
 you want to minimize any uncertainty
 about compliance with your permit.
   (b) In some cases, the NPDES
 permitting authority may recognize,
 either in your individual NPDES permit
 or in an NPDES general permit, that
 another governmental entity is
 responsible under an NPDES permit  for
 implementing one or more of the
 minimum control measures for your
 small MS4 or that the permitting
 authority itself is responsible. Where the
 permitting authority does so, you are
 not required to include such minimum
 control measure(s) in your storm water
 management program. (For example, if a
 State or Tribe is subject to an NPDES
 permit that requires it to administer a
 program to control construction site
 runoff at the State or Tribal level and
that program satisfies all of the
requirements of § 122.34(b)(4), you
 could avoid responsibility for the
construction measure, but would be
responsible for the remaining minimum
control measures.) Your permit may be
reopened and modified to include the
requirement to implement a minimum
control measure if the entity fails to
implement it.

           Federal Register/Vol. 64, No.  235/Wednesday, December 8, 1999/Rules and Regulations     6884'
 § 122.36  As an operator of a regulated
 small MS4, what happens if I don't comply
 with the application or permit requirements
 In §§122.33 through 122.35?
  NPDES permits are federally
 enforceable. Violators may be subject to
 the enforcement actions and penalties
 described in Clean Water Act sections
 309 (b), (c), and (g) and 505, or under
 applicable State, Tribal, or local law.
 Compliance with a permit issued
 pursuant to section 402 of the Clean
 Water Act is deemed compliance, for
 purposes of sections 309 and 505, with
 sections 301, 302, 306, 307, and 403,
 except any standard imposed under
 section 307 for toxic pollutants
 injurious to human health. If you are
 covered as a co-permittee under an
 individual permit or under a  general
 permit by means of a joint Notice of
 Intent you remain subject to the
 enforcement actions and penalties for
 the failure to comply with the terms of
 the permit in your jurisdiction except as
 set forth in §122.35(b).

 § 122.37  Will the small MS4 storm water
 program regulations at §§122.32 through
 122.36 and § 123.35 of this chapter change
 in the future?
  EPA will evaluate the small MS4
 regulations at §§ 122.32 through 122.36
 and § 123.35 of this chapter after
 December 10,2012 and make any
 necessary revisions. (EPA intends to
 conduct an enhanced research effort and
 compile a comprehensive evaluation of
 the NPDES MS4 storm water  program.
 EPA will re-evaluate the regulations
 based on data from the NPDES MS4
 storm water program, from research on
 receiving water impacts from storm
 water, and the effectiveness of best
 management practices (BMPs), as well
 as other relevant information sources.)
  6. In § 122.44, redesignate paragraphs
 (k)(2) and (k)(3) as paragraphs (k)(3) and
 (k)(4), remove the comma at the end of
 newly redesignated paragraph (k)(3) and
 add a semicolon in its place, and add
 new paragraphs (k)(2) and (s) to read as
 follows:

§122.44  Establishing limitations,
 standards, and other permit conditions
 (applicable to State NPDES programs, see
§123.25).
 *****
  (k) * * *
  (2) Authorized under section 402(p) of
CWA for the control of storm water
 discharges;
 *****
  (s) Qualifying State, Tribal, or local
programs. (1) For storm water
 discharges associated with small
construction activity identified in
§ 122.26(b)(15), the Director may
include permit conditions that
incorporate qualifying State, Tribal, or
local erosion and sediment control
program requirements by reference.
Where a qualifying State, Tribal, or local
program does not include one or more
of the elements in this paragraph (s)(l),
then the Director must include those
elements as conditions in the permit. A
qualifying State, Tribal, or local erosion
and sediment control program is one
that includes:
  (i) Requirements for construction site
operators to implement appropriate
erosion and sediment control best
management practices;
  (ii) Requirements for construction site
operators to control waste such as
discarded building materials, concrete
truck washout, chemicals, litter, and
sanitary waste at the construction site
that may cause adverse impacts to water
quality;
  (iii) Requirements for construction
site operators to develop and implement
a storm water pollution prevention plan.
(A storm water pollution  prevention
plan includes site descriptions,
descriptions of appropriate control
measures, copies of approved State,
Tribal or local requirements,
maintenance procedures, inspection
procedures, and identification of non-
storm water discharges); and
  (iv) Requirements to submit a site
plan for review that incorporates
consideration of potential water quality
impacts.
  (2) For storm water discharges from
construction activity identified in
§ 122.26(b)(14)(x), the Director may
include permit conditions that
incorporate qualifying State, Tribal, or
local erosion and sediment control
program requirements by reference. A
qualifying State, Tribal or local erosion
and sediment control program is one
that includes the elements listed in
paragraph (s)(l) of this section and any
additional requirements necessary to
achieve the applicable technology-based
standards of "best available technology"
and "best conventional technology"
based on the best professional judgment
of the permit writer.
  7. Add §  122.62(a)(14) to read as
follows:

§ 122.62 Modification or revocation and
reissuance of permits (applicable to State
programs, see § 123.25).
*****
  (a) * * *
  (14) For a small MS4, to include an
effluent limitation requiring
implementation of a minimum control
measure or measures as specified in
§122.34(b)  when:
  (i) The permit does not include such
measure(s)  based upon the
determination that another entity was
responsible for implementation of the
requirement(s); and
  (ii) The other entity fails to implemenj
measure(s) that satisfy the
requirement(s).
*    *     *    *     *

§ 123.25  Requirements for permitting.
  (a)* *  *

-------
 6885Q    Federal Register / Vol.  64,  No. 235/Wednesday, December 8, 1999/Rules and  Regulations
   (39) § 122.30 (What are the objectives
 of the storm water regulations for small
 MS4s?);
   (40) § 122.31 (For Indian Tribes only)'
 (As a Tribe, what is my role under the
 NPDES storm water program?);
   (41) § 122.32 (As an operator of a
 small MS4, am I regulated under the
 NPDES storm water program?);
   (42) § 122.33 (If I am an operator of a
 regulated small MS4, how do I apply for

 through 122.35?).
 *****
   3. Add § 123.35 to subpart B to read
 as follows:

 § 123.35  As the NPDES Permitting
 Authority for regulated small MS4s, what is
 my role?
   (a) You must comply with the
 requirements for all NPDES permitting
 authorities under Parts 122, 123,  124,
 and 125 of this chapter. (This section is
 meant only to supplement those
 requirements and discuss specific issues
 related to the small MS4 storm water
 program.)
   (b) You must develop a process, as
 well as criteria, to designate small MS4s
 other than those described in
 § 122.32(a)(l) of this chapter, as
 regulated small MS4s to be covered
 under the NPDES storm water'discharge
 control program. This process must
 include the authority to designate a
 small MS4 waived under paragraph (d)
 of this section if circumstances change.
 EPA may make designations under this
 section if a State or Tribe fails to comply
 with the requirements listed in this
 paragraph. In making designations of
 small MS4s, you must:
  (l)(i) Develop criteria to  evaluate
 whether a storm water discharge results
 in or has the potential to result in
 exceedances of water quality standards,
 including impairment of designated
uses, or other significant water quality
 impacts, including habitat and
biological impacts.
  (ii) Guidance: For determining other
 significant water quality impacts, EPA
recommends a balanced consideration
of the following designation criteria on
a watershed or other local basis:
discharge to sensitive waters, high
growth or growth potential, high
population density, contiguity to an
urbanized area, significant contributor
of pollutants to waters of the United
States, and ineffective protection of
water quality by other programs;
  (2) Apply such criteria, at a minimum,
to any small MS4 located outside of an
urbanized area serving a jurisdiction
with a population density of at least
1,000 people per square mile and a
population of at least 10,000;
  (3) Designate any small MS4 that
meets your criteria by December 9,
2002. You may wait until December 8,
2004 to apply the designation criteria on
a watershed basis if you have developed
a comprehensive watershed plan. You
may apply these criteria to make
additional designations at any time, as
appropriate; and
  (4) Designate any small MS4 that
contributes substantially to the
pollutant loadings of a physically
interconnected municipal separate
storm sewer that is regulated by  the
NPDES storm water program.
  (c) You  must make a final
determination within 180 days from
receipt of a petition under § 122.26(f) of
this chapter (or analogous State or
Tribal law). If you do not do so within
that time period, EPA may  make a
determination on the petition.
  (d) You must issue permits consistent
with §§ 122.32 through 122.35 of this
chapter to all regulated small MS4s. You
may waive or phase in the requirements
otherwise applicable to regulated small
MS4s, as defined in § 122.32(a)(l) of this
chapter, under the following
circumstances:
  (1) You  may waive permit coverage
for each small MS4s in jurisdictions
with a population under 1,000 within
the urbanized area where all of the
following  criteria have been met:
  (i) Its discharges are not contributing
substantially to the pollutant loadings of
a physically interconnected regulated
MS4 (see paragraph (b)(4) of this
section); and
  (ii) If the small MS4 discharges any
pollutant(s) that have been identified as
a cause of impairment of any water body
to which it discharges, storm water
controls are not needed based on
wasteload allocations that are part of an
EPA approved or established "total
maximum daily load" (TMDL) that
address the pollutant(s) of concern.
  (2) You may waive permit coverage
for each small MS4 in jurisdictions with
a population under 10,000  where all of
the following criteria have been met:
  (i) You have evaluated all waters of
the U.S., including small streams,
tributaries, lakes, and ponds, that
receive a discharge from the MS4
eligible for such a waiver.
  (ii) For all such waters, you have
determined that storm water controls
are not needed based on wasteload
allocations that are part of an EPA
approved or established TMDL that
addresses the pollutant(s) of concern or,
if a TMDL has not been developed or
approved, an equivalent analysis that
determines sources and allocations for
the pollutant(s) of concern.
  (iii) For the purpose of paragraph
(d)(2)(ii) of this section, the pollutant(s)
of concern include biochemical oxygen
demand (BOD), sediment or a parameter
that addresses sediment (such as total
suspended solids, turbidity or siltation),
pathogens, oil and grease, and any
pollutant that has been identified as  a
cause of impairment of any water body
that will receive a discharge from the
MS4.
  (iv) You have determined that current
and future discharges from the MS4 do
not have the potential to result in
exceedances of water quality standards,
including impairment of designated
uses, or other significant water quality
impacts, including habitat and
biological impacts.
  (v) Guidance: To help determine other
significant water quality impacts, EPA
recommends a balanced consideration
of the following criteria on a watershed
or other local basis: discharge to
sensitive waters, high growth or growth
potential, high population or
commercial density, significant
contributor of pollutants to waters of the
United States, and ineffective protection
of water quality by other programs.
  (3) You may phase in permit coverage
for small MS4s serving jurisdictions
with a population under 10,000 on a
schedule consistent with  a State
watershed permitting approach. Under
this approach, you must develop  and
implement a schedule to phase in
permit coverage for approximately 20
percent annually of all small MS4s that
qualify for such phased-in coverage.
Under this option, all regulated small
MS4s are required to have coverage
under an NPDES permit by no later than
March  8, 2007. Your schedule for
phasing in permit coverage for small
MS4s must be approved by the Regional
Administrator no later than December
10,  2001.
  (4) If you choose to phase in permit
coverage for small MS4s in jurisdictions
with a population under 10,000, in
accordance with paragraph (d)(3) of this
section, you may also provide waivers
in accordance with paragraphs (d)(l)
and (d)(2) of this section pursuant to
your approved schedule.

-------
           Federal Register/Vol.  64, No. 235/Wednesday, December 8,  1999/Rules and Regulations    68851
   (5) If you do not have an approved
 schedule for phasing in permit coverage,
 you must make a determination whether
 to issue an NPDES permit or allow a
 waiver in accordance with paragraph
 (d)(1) or (d)(2) of this section, for each
 eligible MS4 by December 9, 2002.
   (6) You must periodically review any
 waivers granted in accordance with
 paragraph (d)(2) of this section to
 determine whether any of the
 information required for granting the
 waiver has changed. At a minimum, you
 must conduct such a review once every
 five years. In addition, you must
 consider any petition to review any
 waiver when the petitioner provides
 evidence that the information required
 for granting the waiver has substantially
 changed.
  (e) You must specify a time period of
 up to 5 years from the date of permit
 issuance for operators of regulated small
 MS4s to fully develop and implement
 their storm water program.
  (f) You must include the requirements
 in §§122.33 through 122.35 of this
 chapter in any permit issued for
 regulated small MS4s or develop permit
 limits based on a permit application
 submitted by a regulated small MS4.
 (You may include conditions in a
 regulated small MS4 NPDES permit that
 direct the MS4 to follow an existing
 qualifying local program's requirements,
 as a way of complying with some or all
 of the requirements in § 122.34(b) of this
 chapter. See § 122.34(c) of this chapter.
 Qualifying local, State or Tribal program
 requirements must impose, at a
 minimum, the relevant  requirements of
 § 122.34(b)  of this chapter.)
  (g) If you issue a general permit to
authorize storm water discharges from
small MS4s, you must make available a
menu of BMPs to assist regulated small
MS4s in the design and implementation
of municipal storm water management
programs to implement the minimum
 measures specified in §122.34(b) of this
 chapter. EPA plans to develop a menu
 of BMPs that will apply in each State or
 Tribe that has not developed its own
 menu. Regardless of whether a  menu of
 BMPs has been developed by EPA, EPA
 encourages State and Tribal permitting
 authorities to develop a menu of BMPs
 that is appropriate for local conditions.
 EPA also intends to provide guidance
 on developing BMPs and measurable
 goals and modify, update, and
 supplement such guidance based on the
 assessments of the NPDES MS4 storm
 water program and research to be
 conducted over the next thirteen years.
  (h)(l) You must incorporate any
 additional measures necessary to ensure
 effective implementation of your  State
 or Tribal storm water program for
 regulated small MS4s.
  (2) Guidance: EPA recommends
 consideration of the following:
  (i) You are encouraged to use a
 general permit for regulated small MS4s;
  (ii) To the extent that your State or
 Tribe administers a dedicated funding
 source, you should play an active role
 in providing financial assistance to
 operators of regulated small MS4s;
  (iii) You should support local
 programs by providing technical and
 programmatic assistance, conducting
 research projects, performing watershed
 monitoring, and providing adequate
 legal authority at the local level;
  (iv) You are encouraged to coordinate
 and utilize the data collected under
 several programs including water
 quality management programs, TMDL
 programs, and water quality monitoring
 programs;
  (v) Where appropriate, you may
recognize existing responsibilities
among governmental entities for the
control measures in an NPDES small
MS4 permit (see § 122.35(b) of this
chapter); and
   (vi) You are encouraged to provide a
 brief (e.g., two page) reporting format to |
 facilitate compiling and analyzing data
 from submitted reports under
 § 122.34(g)(3) of this chapter. EPA
 intends to develop a model form for this
 purpose.

Congress prior to promulgation of the
new Phase II storm water regulations.
The Report was required in the
Agency's appropriation legislation for
fiscal  year 2000. The appropriation
legislation also requires that USEPA
invite public comment on the Report.
By this notice, USEPA invites public
comment.
DATES: Written comments on this notice
and the Report to Congress must be
submitted on or before January 7, 2000.

sw2@epamail.epa.gov.
SUPPLEMENTARY INFORMATION: On
October 29, 1999, the Administrator of
EPA signed a regulation that
implements Section 402(p)(6) of the
Clean Water Act. This rulemaking is
referred to as the final Phase II storm
water rule and is also published in
today's Federal Register.
  The Phase II storm water rule expands
the existing National Pollutant
Discharge Elimination System (NPDES)
permitting program to address storm
water runoff from construction sites
between one and five acres and
municipal separate storm sewer systems
in urbanized areas serving populations
of less than 100,000. The Phase II rule
builds on the existing Phase I program,
which controls storm water runoff from
municipalities with populations greater
than 100.000 and 11 industrial
categories, including construction
disturbing over five acres.

Statutory Authority
  The Report to Congress on the Phase
II Storm Water Regulations was required
bv section 431(a) of the Departments of
Veterans Affairs and Housing and Urban
Development and  Independent Agencies
Appropriations Act of 2000, Public Law
l()f.-74  (1999) (Appropriations Act).
Section 431 (a) of the Appropriations Act
directed EPA to submit a report that
addresses the following issues with
respect to the Phase II Storm Water
Rule: (1) An analysis of the impact of
the rule on local governments, (2) an
explanation of the rationale for lowering
the threshold for regulation of
construction sites from 5 acres to 1 acre,
(3) an explanation of why the coverage
of the regulation is based on a census-
determined population instead of a
water quality threshold and
documentation that storm water runoff
is generally a problem in communities
with populations of 50,000 to 100,000,
and (4) information that supports the
position of the Administrator that the
Phase II storm water program should be
administered as part of the NPDES
permit program.
  On October 28, 1999, EPA delivered
to the Committee on Environment and
Public Works in the Senate and the
Committee on Transportation and
Infrastructure in the House of
Representatives a report that satisfied
the mandate of section 431{a). Section
431(c) of the Appropriations Act directs
EPA to publish the report in the Federal
Register for public comment. By today's
notice, EPA invites public comment by
January 7, 2000. EPA will carefully
review and evaluate comments received
and determine whether the comments
warrant further action.
  Dated: November 4, 1999.
