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

 SUMMARY: The Water Quality Act
 (WQA) of 1987 added section 402(p) to
 the Clean Water Act (CWA). Section
 402(p) of the CWA requires the
 Environmental Protection Agency [EPA)
 to establish phased and tiered
 requirements for storm water discharges
 under the National Pollutant Discharge
 Elimination System (NPDES) program.
 On August 16,1991 (56 FR 40948). EPA
 requested public comments on several
 regulatory and policy issues regarding
 NPDES permits for storm water
 discharges associated with industrial
 activity. On November 5,1991 (56 FR
 56549), the Agency also proposed
 extending the deadline for submitting
 part 2 of group applications for storm
 water discharges associated with
 Industrial activity.
  In response to comment received on
 August 10,1991,  proposal, today's action,
 describes a National Strategy for issuing
 NPDES permits for storm water
 discharges associated with industrial
 activity. Today's action also contains a
 final rule that revises minimum NPDES
 monitoring requirements for storm water
 discharges associated with industrial
 activity. In addition, today's rule
 establishes minimum requirements for
 filing  notices of intent to be authorized
 to discharge under NPDES general
 permits.
  Today's rule also establishes a
 deadline of October 1,1992 for part Z of
group applications for storm water
discharges associated with industrial
activity. As noted above, this revised
deadline w,as proposed on November 5,
1901.  In connection with group
applications, today's rule contains an
amendment  to clarify the minimum
number of facilities that must submit
sampling information in part 2 of a group
application.
  Finally,  today's action codifies several
provisions of Section 1068 of the
Intcrm odal "Surface Transportation
Efficiency Act of 1991 or Transportation
Act Into the I^PDES regulations. Section
 1068 of the Transportation Act
 addressed permit application deadlines
 for storm water discharges associated
 with industrial activity from facilities
 that were owned or operated by
 municipalities.                   N  ,
 EFFECTIVE DATE: The final rule becomes
 effective May 4,1992.

 I. Background
  The 1972 amendments to the Federal
 Water Pollution Control Act (FWPCA,
 also referred to as the Clean Water Act _
 or CWA), prohibited the discharge of
 any pollutant to navigable waters from a
 point source unless the discharge is
 authorized by a NPDES permit. Efforts
 to improve water quality under the
 NPDES program have focused
 traditionally on reducing pollutants in
 discharges of industrial process
 wastewater and from municipal sewage
 treatment plants. This program
 emphasis has developed for a number of
 reasons. At the onset of the program in
1972, many sources of industrial process
wastewater and municipal sewage-were
not controlled adequately, and
 represented pressing environmental
 problems. In addition, sewage outfalls
 and industrial process discharges were
 easily identified as responsible for poor,
 often drastically degraded water quality
 conditions. However, as pollution
 control measures were developed
 initially for these discharges, it became-
 evident that more diffuse sources
 (occurring over a wide area) of water
 pollution, such as agricultural and urban
 runoff, were also major causes of water
 quality problems. Some diffuse sources
 of water pollution, such as agricultural
 storm water discharges and irrigation
 return flows, are exempted statutorily
 from the NPDES.program. Controls for
 other diffuse sources have been slow to
 develop under the NPDES program.
 A. Environmental Impacts

  Several national assessments have
 been conducted to evaluate impacts on
 receiving water quality. For the purpose
 of these' assessments, urban runoff was
 considered to be a diffuse source or
 nonpoint source pollution, although in
 legal terms, most urban runoff is
 discharged through conveyances such as
 separate storm sewers or other   '•
 conveyances which are point sources
 under the CWA and subject to the
 NPDES program.
  The "National Water Quality
 Inventory, 1990 Report to Congress"
 provides a general assessment of water
 quality based on biennial reports
 submitted by the States under section
 305(b) of the CWA. In preparing section
 305(b) Reports, the States were asked to'
 indicate the fraction of the States'
 waters that were assessed, as well as
 the fraction of the States' waters that
 were fully Supporting, partly supporting,
 or not supporting designated uses. The
 Report indicates that of the rivers, lakes,
 and estuaries that were assessed by
 States (approximately one-third of
 stream miles, one-half of lake acres and
 three-quarters of estuarine waters),
 roughly 60 percent to 70 percent are
 supporting ..the uses for which they are
 designated. For waters with use         ••'
 impairments, States  were asked to
 determine impacts due to diffuse
 sources (agricultural and urban runoff
 and other categories of diffuse sources),
 municipal sewage, industrial (process)
 wastewaters, combined sewer
 overflows, and natural sources, and then .
 to combine impacts to arrive at
 estimates of the relative percentage of  .
State waters affected by each source. In
 this manner, the relative importance of
 the various sources of pollution causing
use impairments was assessed and
weighted national averages were
calculated.  -'•'.''•      .

  Based on 51 States and Territories
that provided information on sources of
pollution, the Assessment also
concluded that pollution from "diffuse
sources such as runoff from agricultural,
urban areas, construction sites, land
disposal activities, and resource
extraction activities is cited by the
States as the leading cause of water
quality impairment.1 Diffuse sources
appear to be increasingly important
contributors of use impairment as

11396       Federal Register / Vol.  57.  No. 64  /  Thursday, April 2, 1992 / Rules and Regulations
Industrial activity: Individual permit
applications and group applications. In
addition, the notice recognizes a third
act of application procedures for storm
Mater discharges associated with
industrial activity: Those associated
with general permits. With these
requirements, EPA is attempting to
Implement a flexible, cost-effective
approach for storm water permit
applications.
  The requirements for individual
applications for storm water discharges
associated with industrial activity are
                     .c.^., . — -t—
     ,,4            lity specific narrative
information including: (1) A site map; (2)
an estimate of impervious areas; (3) the
identification of significant materials
treated or stored on site together with
associated materials management and
disposal practices: (4) the location and
description of existing structural and
non-structural controls to reduce
pollutants in storm water runoff; (5) a
certification that all storm water outfalls
have been evaluated for any
unpefmiUed non-storm water
discharges; and (6) any existing
information regarding significant leaks
or spills of toxic or hazardous pollutants
within threa years prior to application
submiltal. In addition, an individual
application must include quantitative
analytical data based on samples
collected on site during storm events.
Under § 122,26(e)(l) of the November 16.
2890 rule, individual applications were
to have been submitted by November 18,
  The group application process allows
for facilities with similar storm water
discharges to file a single two part
permit application. Part 1 of a group
application includes a list of the
facilities applying, a narrative
description summarizing the industrial
activities of participants  of the group, a
list of significant materials exposed to
precipitation that are stored by
participants and material management
practices employed to diminish contact
of these materials by precipitation (see
40 CFR 122.26(c)(2)(i)). Under the
November 18, 1990 regulations, Part 1 of
the group application was to be
submitted to EPA no later than March
18, 1991.* The regulation provides that
 EPA has a 60 day period after receipt to
 review the part 1 applications and notify
 the groups as to whether they have been
 approved or denied as a properly
 constituted "group" for purposes of this
 alternative application process. Part 2 of
 the group application contains detailed
 information, including sampling data, on
 roughly ten percent of the facilities in
 the group (today's notice contains a
 more detailed description clarifying the
 requirements of 40 CFR 122,26(c)(2)(ii)).
.Under the November 16,1990
 regulations, part 2 applications were to
 be submitted no later than 12 months . .
  * The deadline for submitting an individual permit
application for norm water discharges associated
with indiiitrul activity wai extended from
November 18, 1881 to October 1. 1992 (56 FR 56548,
are discussed below). Also underThe
November 16,1990 regulation, facilities
that are rejected as members of a group
were to have 12 months from the date
they receive notification of their
rejection to file an individual permit
application (or obtain coverage under an
appropriate general permit).8
  The group application process has
been designed by EPA as a one-time
administrative procedure to ease the
burden on the regulated community and
permitting authorities in the initial stage
of the storm water program.
  The third application'prbcedufe
entails seeking coverage under a general
permit for storm water discharges
associated with industrial activity.
Dischargers covered by a general permit
are excluded under 40 CFR 122.21(a)
from requirements to submit individual
or group permit applications. Conditions
for filing an application to be covered by
a general  permit (typically called a
Notice of Intent (NOI)) are established
on a case-by-case, basis. As discussed in
more detail below, today's notice
establishes final minimum requirements
for general permit NOI submissions.
  The November 16,1990 regulations
also establish a two part application  •
process for discharges from municipal
separate storm sewer systems serving a
population of 100,000 or more. The
regulations lists 220 cities  and counties
that are defined as having municipal
separate storm sewer systems serving a
population of 100,000 or more and
allows for case-by-case designations of ,
other municipal separate storm sewers
to be part of these systems (55 FR 48073,
48074). The regulations provide that part
1 applications for discharges from large
municipal separate sjtorm sewer systems
  * The deadline for submitting part 1 of the group
•(tpltcntion wa» extended from March 18, 1991 to
September 30. 1801 (58 FR 1209S (March 21. 1991}).
  * The deadline for a facility that is rejected as a
member of a group application to submit an
individual permit application has been revised to
provide that an Individual application must be
submitted no later than 12 months after the date-of
receipt of the notice of rejection or October 1,1992,
whichever comes first (56 FR 56549, {November 5,
1991}).
                                        (systems serving a population of 250,000
                                        or more) were due November 18, 1991.
                                        Part 2 applications for discharges1 from
                                        large systems are due on November 16,
                                        1992. Part 1 applications for discharges

 13398       Federal Register / Vol. 57, No.  64 / Thursday,  April 2.  1992 / Rules and Regulations
   » Tier II—Watershed Permitting:
 Facilities within watersheds shown to
 be adversely impacted by storm water
 discharges associated with industrial
 activity will be targeted for individual or
 watershed-specific general permits:
   • Tier til—Industry-Specific
 Permitting: Specific industry* categories
 will be targeted for individual or
 Industry-specific general permits; and
   * Tier IV—Facility-Specific
 Permitting; A variety of factors will be
 used to target specific facilities for
 Individual permits.
   These four classes of activities will be
 implemented over lime and will reflect
 priorities within given States. In most
 States, tier I activities, issuance of
 baseline permits, will be the initial
 starting point. As priorities and risks
 within the State are evaluated, classes
 of storm water discharges or individual
 atorm water discharges will be
 identified for tier II, HI or IV permitting
 activities. Usually a  storm water
 discharge or a class  of discharges will
 not go through a sequence that involves
 all four of the tiers associated with the
 strategy, but may for example, go from
 Initial coverage under a Tier I baseline
 permit to coverage under a tier III
 Industry-specific general permit.
   a. Tier I—Baseline permitting. Tier I
 general permits can initially cover  the
 majority of storm water discharges
 associated with industrial activity in a
 State. Consolidating many sources
 under a general permit greatly reduces
 the administrative burden of issuing
 permits for storm water discharges
 associated with industrial activity.
 Under this approach:
   • Pollution prevention and/or best
 management practices will be
 established for discharges covered by
 the permit;
   • Facilities whose discharges are
 covered by the permit will be certain of
 their legal responsibilities and have an
 opportunity to comply with the CWA;
   » EPA and authorized NPDES States
 will begin to collect and review data on
 storra water discharges from priority
 industries, thereby supporting
 subsequent permitting activities;
   * The public, including municipal
 operators of municipal separate storm
 sewers which may receive storm water
 discharges associated with industrial
activity, will have the opportunity to
review data and reports developed by
 Industrial permittees under section
30«{b)oftheCWA;
   * The baseline permits will provide a
 basis for coordinating requirements for
storm water discharges associated with
industrial activity with requirements of
municipal storm water management
programs In permits for discharges from
 municipal separate storm sewer
 systems.
   • The baseline permits will provide a
 basis for bringing selected enforcement
 actions; and
   • The baseline permit, along with the
 State storm water permitting plans
 (discussed below), will provide aJocus
 for public comment on draft permits and
 subsequent phases of the permitting
 strategy for storm water discharges.
   Initially, the coverage of the  baseline
 permits will be broad. However, it is
 anticipated that coverage will become
 more specific and targeted as other
 permits are issued for, storm water
 discharges associated with industrial
 activity pursuant to tier II through tier
 IV activities. The Agency believes that
 tier I permits can establish the
 appropriate balance between monitoring
 requirements and implementable
 controls that will initiate facility-specific
 controls and provide sufficient data for
 compliance monitoring and future , .
 program development. Baseline general
 permits are flexible enough to allow the .
 inclusion of tier II, III or IV types of
 permit conditions, such as industry
 specific monitoring or control conditions
 into the baseline general permit.       :
   b. Tier II—Watershed permitting.
 Issuing permits on a watershed basis is
 potentially a desirable way to cost  •
 effectively use Agency resources to
 satisfactorily address risk. Facilities
 within watersheds-shown to be
 adversely impacted by storm water '
 discharges associated with industrial
 activity will be targeted for individual
 and more specific general permitting
 activities. This process .can be initiated
 by identifying receiving waters (or  -
.segments of receiving waters) where
 storm water discharges associated with
 industrial activity have been identified
 as a source of use impairment or are
 suspected to be contributing to  use
 impairment. Information developed
 under sections 304(1), 305(b), and 319(a)
 of the CWA, along with information
 from other sources (including
 information developed under the
 baseline general permits for storm water
 discharges), can be used in evaluating
 impacts on receiving waters. This
 information may identify classes of
 storm water discharges that are of
 particular concern and portions of
 watersheds where the sources of
 concern are located. Appropriate
 classes of storm water discharges in
 these locations can be targeted  for
 additional permit conditions which may
 provide for additional information to
 characterize the discharge (e.g.,   •
 additional monitoring and reporting
 requirements) or,  where appropriate, for
 more stringent controls.
    information gathered under initial
  permits for storm water discharges as
  well as information from other sources
  can be used to reassess waterquality-
  based controls. As discussed in more
  deiail below, State storm water
  permitting strategies are expected to
  have a major role in this process.
    c. Tier HI—-Industry-specific
 permitting. Specific industry categories
  will be targeted for individual or
  industry-specific general permits. These
  permits will allow permiting authorities
  to focus attention and resources on
  industry categories of particular concern
  and/or industry categories where
, tailored requirements are appropriate.
 The Agency will work with the States to
  develop model permits for selected
 classes of industrial storm water
 discharges. In addition, the group
 application process adopted in the
 November 16,1990 regulation, (55 FR
 47990) will provide an additional
 mechanism for developing industry-
 specific general permits. Group     ;
 applications that are received can be
 used to develop model permits for the
 appropriate industries. -.
   d. Tier IV—Facility-specific       ,
 permitting, individual permits will be
 appropriate for some storm water
 discharges in addition to those
 identified under tier II and tier HI
 activities. Individual permits should be
 issued where warranted by the
 environmental risks of the discharge,  the
 need for additional and more complex
 individual control mechanisms, a
• facility's compliance history or the
 potential to consolidate permit
 requirements for a particular facility. For
 example, individual NPDES permits for
 facilities with process discharges should
 be expanded during the normal process
 of permit reissuance to cover storm
 water discharges from the facility. This
 provides an opportunity to develop more
 facility specific individual controls
 without greatly increasing incremental
 administrative burdens.
 2. State Storm Water Permitting Plans
   EPA believes that State Storm Water
 Permitting Plans provide an effective
.basis for ensuring adequate public input,
 evaluating program activities and
 priorities, and providing program
 oversight during the earlier stages of
 program development. These plans Will
 provide an effective coordination and
 tracking mechanism for evaluating the
 initial permitting activities for storm
 water discharges required under section
402(p) of the CWA. In addition, State
Storm Water Permitting Plans will
provide,a framework within which to
coordinate and asses the relationship

-  affected by components of the plans.

  3. States vvithout NPDES 'General Permit
  Authority      ,         •••'

''-. As noted, the issuance of general'
  permits is an important component in
  the recommended permit issuing
  strategy. Presently 38 States (and 1    :
 territory) have been authorized to
 implement the NPDES permit program.
 However, only 29 of these States have
 beefi-authorized to issue general
 permits. If NPDES authority is not
 obtained for any of the remaining 10
 States, individual NPDES permits based
 on the submission-of individual or group
 applications will have to be issued for
 storm water discharges associated with
 industrial activity. It is important to
 emphasize that under the CWA, EPA    .
 cannot issue general permits in States:
that have been authorized to administer
 the base NPDES program.     •:"' '
   EPA strongly recommends authorized
NPDES States without general permit
 authority to obtain general permit
authority as soon as possible. EPA is
currently working with these States to
provide technical assistance and
support and to expedite the
authorization process.

4. Response to Comments
  a. T/credpriorities. Many commenters
agreed that EPA and authorized NPDES
States should prioritize permit issuance
efforts for storm water discharges
associated with industrial activity, and
Indicated that the tiered priorities
identified by EPA generally establish an
appropriate conceptual framework for
such efforts. These commenters
generally indicated that the four tier
strategy provides appropriate
opportunities to identify high-risk
discharges. In response, the Agency
agrees and is retaining the four tiered
set of priorities as discussed in the
August 10,1991 proposal.
  Some commenters indicated that they
thought EPA and authorized NPDES
States should be bound to implementing
the tiered priorities consecutively in the
order reflected by the four tiers. These
commenters indicated that the draft
general permits noticed on August 16,
19»1 by EPA violated the tiered priority
approach because the permits contained
some permit conditions which were
above a tier I baseline set of pollution
prevention measures. EPA disagrees
with these comments. The Agency
wants to clarify that it only intends the
four tiered set of priorities  to be used as
a general conceptual framework which
can be used to describe efforts to issue
permits, The strategy for setting storm
Water permit issuance priorities is not
Intended to be a set of regulatory
requirements binding on EPA, States, or
Industrial dischargers. Articulating
tiered priorities docs not legally restrict
conditions in permits issued by EPA or
authorized NPDES States. Rather all
NPDES permits, including permits for
storm water discharges associated with
industrial activity, must be in
compliance with sections 301 and 402 of
the CWA. A major purpose of
articulating tiered priorities is to assist
in identifying and developing
appropriate permit conditions for high-
risk facilities. Tier I baseline general
permits which have some of the
characteristics of tier II or III permits are
consistent with these objectives.
  b. Stale Plans. Some States supported
the concept of Plans, but were
concerned that scheduling plan
development one year after the date of
today's rule would hinder the initial
development of storm water programs in
a number of States. These commenters
indicated that the NPDES storm water
program  would be in its initial stage of
implementation and authorized NPDES
States would  be busy conducting a
number of critical activities such as
obtaining general permit authority.
issuing bosehne general permits, and
issuing permits for discharges from large
and medium municipal separate storm ,
sewer systems. They indicated that .
these activities could be disrupted if
States placed top priority on developing
and submitting plans within a year of
today's action. EPA agrees with these  .
concerns, and believes that while  -
development of these plans should begin
early in the storm water permit issuance
process to help guide implementation,
draft plans do not need to be prepared
for submission until April 3,1995.
  One State stressed that permitting
plans were necessary to assure national
equitability and prevent economic
disincentives in States with progressive
storm water management programs;
EPA believes that one of its goals in.
overseeing the development of the
NPDES program is to ensure that NPDES
permits for storm water discharges
reflect the requirements of the CWA in
an equitable manner that reflects the
technology-based and water quality-
based requirements of the CWA* At the
same time, the Agency recognizes the
need to provide sufficient regulatory '
flexibility to allow States to make'
rational and reasonable permitting
decisions. For example, today's rule
provides  permit writers with additional
flexibility, to target high risk discharges
and establish group or facility specific
monitoring and reporting requirements
in NPDES permits for storm water
discharges associated with industrial
activity. In addition, permit conditions
for most classes of storm water
discharges will be established on a
case-by-case basis. Nonetheless, the
Agency agrees with the commehter that
State Storm Water Permitting Plans can
provide an important tool to ensure that
NPDES storm water programs in
different  States reflect pollution control
requirements consistent with the CWA
while maintaining the adequate
flexibility necessary to successfully
implement the NPDES storm water
program.
  Several authorized NPDES States did
not support the idea of State Storm
Water Permitting Plans, but rather
indicated that annual EPA/State
agreements could be used as a tool, for
oversight of the NPDES storm water
program. In response, the Agency
believes that the approach in the Plans
is consistent with and  can be
implemented as a component of annual
EPA/State agreements if there is an
adequate level of detail and specificity
and the State and EPA Region agree on
including the elements noted above as
part of die annual oversight process. The
Agency believes that by publishing a
framework for these Plans, it will
provide States with notice of necessary
Plan elements, provide a nationally
consistent approach for evaluating
program progress, facilitate technology
transfer activities, encourage public
participation, and ensure that risks are
evaluated ion the context of the entire
NPDES storm water program.   -
  In the August 16,1991 notice, the
Agency requested comments on whether
the guidelines for Plans should be made
requirements that are incorporated into .
EPA regulations, or remain non-binding
recommendations for States. Most of the
commenters that responded to this issue
urged EPA to make the guidelines for
Plans non-binding recommendations for
the States. While EPA notes that it may
require preparation of such Plans
pursuant to Section 402(p)(6) of the
CWA, the Agency agrees with the
commenters that establishing guidelines
for Phase I storm water permitting plans
as non-bin'ding recommendations
provides an amount of flexibility that is
appropriate at this point in the
program's development. Therefore, the
Agency is clarifying that the guidelines
for Phase I Plans and the request to
prepare and submit Plans to EPA are
non-binding recommendations ;at this
point in time.
B. Minimum Monitoring and Reporting
Requirements for Storm Water
Discharges
  Current NPDES regulations at 40 CFR
122.44(i)(2) provide that all NPDES
permits are to establish.requirements to
report monitoring results with a
frequency dependent on the nature and
effect of the discharge, but in no case
less than once a year. In the August 16,
1991 proposal, EPA requested comment
on six major options for modifying 40-
CFR 122.44(i)(2) to provide minimum
monitoring and reporting requirements
specifically addressing storm water
discharges associated with industrial
activity.  '
•  In the August 16,1991 proposal, the
Agency identified a number of factors
that it would consider when evaluating
this issue:
•  Difficulties in Sample Collection—
Collection of storm water samples may
pose a number of potential difficulties.
These difficulties include determining
when a discharge will occur, safety
considerations, the potential for a
multiple  discharge points at a single
facility, the intermittent nature of the
event, the limited, number of events tha t
occur in some parts of the country, and
variability in flow rates.

monitoring conditions in NPDES permits
for storm water discharges.
  Other commcnters suggested that EPA
should allow alternatives to monitoring.
Some commcnters urged the Agency to
expand option 3 to allow other classes
of facilities in addition to oil and gas
operations to obtain a PE certification,
to allow facility operators to conduct
inspections, or certify compliance with a
checklist of pollution prevention
measures or best management practices
(IMPs) in lieu of sampling. Other
commcnters suggested that other
individuals were as qualified or more
qualified than PEs to perform site
inspections and that additional
flexibility should be provided with
regard to the inspection requirement.
For example, some commenters
indicated that certified construction
Inspectors were more appropriate for
conducting Inspections at construction
sites than PEs, who might not be
familiar with soil and erosion practices
or storm water management
technologies. Other commenters
   gnsted that site personnel would
typically be in the best position to
evaluate the implementation of pollution
prevention measures and BMPs.
  Other comments urged EPA to
consider the costs and technical
difficulties qf sample collection and
analysis when establishing minimum
monitoring requirements, and
encouraged the Agency to consider
alternatives to discharge sampling, such
as allowing site inspections in lieu of
monitoring. In the August 16.1991
notice. EPA had requested comments on
monitoring requirements for inactive
mining operations, and some comments
specifically addressed this issue.
& Today's Rule
  In response to comments, today's
rulemaking adopts an approach that is a
combination or hybrid of a number of
options identified in the August 16.1991
proposal, particularly options 3 and 5.
The final rule provides for establishing
monitoring conditions in NPDES permits
for storm water discharges associated
with industrial activity on a case-by-
case basis. At a minimum, a permit for
such a discharge must require the
discharger to conduct an annual
inspection of the facility site to identify
areas contributing to a storm water
discharge associated with industrial
activity and evaluate whether measures
to reduce pollutant loadings identified in
8 storm water pollution prevention plan'
arc adequate and properly implemented
in accordance with the terms of the
permit and the plan or whether
additional control measures are needed.
The discharger must be required to
maintain for a period of three years a
record summarizing the results of the
inspection and a certification that the
facility is in compliance with the plan
and the permit, or identifying any
incidents of non-compliance. Such
report and certification must be signed
by a corporate official in accordance
with 40 CFR 122,22.
  Today's rule establishes a minimum
requirement for annual inspections for
most storm water discharges associated
with industrial activity..The Agency
believes that a minimum frequency of at
least annual inspections is appropriate
to ensure evaluation of changing
conditions and practices at a site,
(especially those caused by wet weather
and winter conditions occurring
throughout a year) and to ensure
adequate implementation of pollution
prevention measures on a regular basis.
While options of the August 16,1991
proposal had requested comment on a
minimum frequency of every three years
for a PE certification for oil and gas
operations and certain inactive sites, the
Agency believes that providing
additional flexibility in who  conducts
site inspections will sufficiently lower
compliance costs in some cases to allow
a higher frequency of inspections to be
feasible. As discussed below, the
Agency is providing additional
flexibility in establishing monitoring or
inspection requirements for storm water
discharges from inactive mining
operations. No commenters on the draft
general permits in the August 16,1991
Federal Register notice specifically
indicated that it would be infeasible to
comply with requirements in the draft
general permits to conduct annual
inspections. The Agency believes that a
minimum annual frequency of
inspections compensates for less formal
requirements with respect to specifying
who must conduct the inspection. A
minimum annual frequency is also
consistent with the minimum
requirements for discharges  other than
storm water to report monitoring
information at least annually.
  A minimum of an annual inspection or.
report of monitoring results is not
required for storm water discharges
associated with industrial activity from
inactive mining operations where
annual inspections are impracticable.
Rather, permits for storm water
discharges from inactive mining
operations may require certification
once every three years by a  Registered
Professional Engineer that the facility is
in compliance with the permit, or
provide for alternative requirements.
This provision will provide additional
flexibility to address inactive mine
operations.- Mining activities ;have a
somewhat unique history Of '  ".
development and inactive mining sites-
can be dispersed diffusely in remote,
hard to reach locations where
employees may typically not be onsite
to conduct site evaluations. In addition,
the inactive nature of these sites may
limit changes to potential for storm
water discharges from the site to
contain pollutants, thereby warranting
less frequent inspections. The Agency
anticipates that certification by
Professional Engineers may often be
appropriate for these sites given the
nature of typical controls for these sites,.
and the. limited amount of activity
.occurring at them. Alternative
requirements may be appropriate for
storm water discharges from inactive
mining operations in some
circumstances. For example, storm
water discharges from inactive mining
operations on Federal lands where an
operator cannot, be identified present
unique circumstances because of the
remote nature and high number of sites
on large Federally owned areas.
   The Agency believes that this rule will
provide sufficient flexibility for permit
writers to establish monitoring
requirements that reflect the potential  .
risk of the discharge and that are
appropriately related to the nature of the
permit conditions for a discharge.
Today's regulatory modification does
not preclude discharge sampling and
reporting requirements in NPDES
permits for storm water discharges
associated with industrial activity.
While today's rule change provides
additional flexibility to establish
monitoring requirements, it does not
limit  the authority of EPA or authorized
NPDES States to establish sampling
requirements where appropriate based
on'a consideration .of risk or other
factors.             •
   The Agency recognizes that different
types of permit conditions are
appropriate for different types of storm
water discharges. Numeric effluent  -
limitations are appropriate for some
classes of storm water discharges. End-
of-pipe numeric effluent limitations are
typically used for some types or classes
of storm water discharges associated
with  industrial activity.8 Typically,
NPDES permits for these classes of
discharges will contain numeric effluent
limitations, and sampling requirements
will be appropriate for these  permits,  .
   8 For example, the Agency has issued numeric;
 effluent limitation guidelines for ten classes of
 discharges that are composed entirely of storm.
 water or of storm water combined with process
 water.     .        -'-'••

              raised concerns regarding sampling

              classes of industries. For example,
              representatives' of the construction

Professional Engineer's (PE) certification
attesting that good engineering practices
were being employed to meet
appropriate permit conditions. The
Agency requested comment on whether
the PE certification was appropriate and
whether it should be extended to other
clfttsei of facilities,
  Some commenters suggested that
other individuals were as qualified or
more qualified than PEs to perform site
inspections and that additional
flexibility should be provided with
regard to the inspection requirement.
For example, some commenters
Indicated that certified construction
Inspectors were more appropriate for
conducting inspections at construction
sites than PEs who might not be familiar
with soil and erosion practices or storm
water management technologies. Other
commenters suggested that site
personnel would typically be in the best
position to evaluate the implementation
of pollution prevention measures and
BMPs, In response, today's rule provides
flexibility to allow site inspections to be
conducted by persons other than PEs.
While the Agency believes it is
appropriate to require PE certifications
in certain circumstances, the approach
taken with today's rule will provide
additional flexibility in developing these
requirements,
  A number of commenters suggested
that PE certifications were appropriate

for classes of storm water discharges
associated with industrial activity other
than those from oil and gas operations.
These commenters indicated that such a
certification could, in many cases, be
less burdensome than discharge *
monitoring, and that  such certifications
could provide a closer link to
compliance with pollution prevention'
measures and best management
practices. As discussed above, today's
rule provides that requirements to
conduct annual site inspections can be
established as minimum monitoring
requirements in permits for storm water
discharges. The Agency agrees with
these comments to the extent that it is
convinced that site inspections can
provide an appropriate means for
evaluating compliance with pollution
prevention measures and best
management practices for storm water
discharges from different types of
facilities. In addition, site inspections
can be less burdensome than sampling
storm water discharges for some
facilities. Requiring annual Inspections
and reviewing documentation as part of,
routine compliance inspections or at the
time of permit reissuance also makes
effective use of the limited resources of
permit issuance authorities, by allowing
permit issuing agencies more time to
focus on issues other than receiving,
reviewing and filing monitoring data.
  Some commenters indicated that EPA
and authorized NPDES States should
only require facilities to monitor storm
water discharges associated with
industrial activity where the permit
issuing agencies can evaluate the data.
The Agency recognizes that EPA and
some authorized NPDES  States cannot
provide adequate resources to ensure
that all discharge monitoring data can
be inspected. However, the Agency
believes that even where discharge
monitoring data is hot reviewed on an
ongoing basis by a permit issuing
authority, the data can still be very
useful. Facilities which discharge should
review their discharge sampling data to
identify sources and types of pollutants
in discharges, and to evaluate the
effectiveness of pollution prevention
measures and BMPs. Where an NPDES
permit does not require a discharger to
report sampling data, EPA or an
authorized NPDES State  will typically
be able to request the data on a case-by-
case basis, or request that the data be
submitted for consideration prior to
permit reissuance.
  Some commenters expressed concerns
about minimum monitoring requirements
for storm water discharges from inactive
mining operations. EPA agrees that in
some circumstances, discharge sampling
or annual inspections nfay be
particularly burdensome at inactive
mining operations, because mining
operations often are found in remote
areas that are not necessarily supported
by infrastructure that allows easy
access. In addition, at some inactive
mining operations, inspections may not
be as integrally related to pollution
prevention  measures for storm water
discharges  associated with industrial
activity, as pollution prevenjjon
measures will not focus on day to day
management activities. EPA  has
modified today's rule accordingly.
  A number of commenters addressed
the specific monitoring requirements in,
the draft general permits for  s'torm water
discharges  associated with industrial
activity in the August 16,1991 notice.
The Agency wants to clarify that the
amendments to 40 CFR 122.44(i}(2) in

C.,Application Requirements for
General Permits        '    .
  The provisions of 40 CFR 122.21(a)
exclude persons covered by  general
permits from requirements to submit
individual permit applications.
Currently, the general permit regulations
at 40 CFR 122.28, however, do not    .
address the issue of how a potential
permittee is to apply to be covered
under a general permit. Rather,
conditions  for filing an application to be
covered by-a general permit  (typically
called a Notice of Intent (NOI)) have
been established on a case-by-case
basis. NOI  requirements established in
general permits operate instead of
individual permit application
requirements for the discharges covered
by the general permit.
1. August 16,1991 Proposal

  The August 16,1991 notice proposed
several modifications to the  NPDES
regulatory framework for general
permits. (The proposed changes
addressed NPDES general permits for all
classes of discharges and sludge
disposal, and was not limited to storm
water discharges). The proposal
addressed procedures for becoming ..  '
authorized to discharge under a general
permit, minimum requirements for NOIs
to be covered by a general permit, and
deadlines for submitting NOIs.

-------
 .;  2. Today's Rule

       Today's rale finalizes modifications to
     the NPDES regulatory framework for
 ,    general permits addressing procedures
     for becoming authorized to discharge   "
     under ah NPDES general permit,  v ..•-.•
     minimum requirements for notices of
.  .intent (NO!) to be coveredby a general
   ^permit, and deadlines for submitting  ;>
-'   NOIs, :    ;  '!:;:"..." \,;'.';. ;•>/'• ;   ;,"'"
      The regulatory framework provided
  :  by today's rule requires that,-except for
    in two situations, an NOI must be  '
   ;submitted by a^discharger (or treatment;
    works treating domestic sewage) inr
    order to be authorized to discharge (or
    in the case of a sludge disposal permit,
    to engage in a sludge use or disposal
   practice] under an NPDES general  r
   permit. The first situation where'an NOI
   will not have to be submitted to
  ; authorize discharges un^er a general
   permit is w,here the Director notifies the
   , discharger that its discharge is covered
  v by the permit. The second situation ';  "
   where NOIs are not. required under a
   general permit is where the'Director'
  /provides  in the general permit that a
   submission of an NOI is not requiredi
   where the Director finds that ari NOf
   requirement is inappropriate for that -
   general permit v "•..   -.'• - " ': T    ,
 •'.;  _  In making a~decjsion that an Nbl iff
   inappropriate for a general permit, the
   Director will consider the type of
   discharge, the expected nature of the
   discharge, the potential for toxic and
   conventional pollutants'in the
   discharges, the expectpd,vollume of the
   discharges, other means of identifying
  .discharges covered by the permit, and
   the esumated number of discharges to
   be covered by the permit. Also, in
 .. making this decision, the Director is
   required to describe the reasons for not
  requiring an NOIin the fact sheet of the
  general permit. Under, today's rule; such
  a finding could only be made for
  .discharges other than discharges from
  POTWs, combined  sewer overflows
  (CSQs), primary industrial facilities, and
 .storm water discharges associated with
  industrial activity. The Agency believes
  that, given the potential environmental
  significance and NPDES-prpgram
  priorities associated with discharges
  from POTWs, CSOs, primary industrial
  iacilihes, and storm water discharges
 Associated with industrial activity, it is
  appropriate to require NOIs in all
 general permits for these discharges   ;
   Today's rule establishes minimum':  '
 requirements for NOIs in NPDES general
 permits at 40 CFR 122,28(b)(2)(iiJ. This
 provision requires that the contents of
 the notice ofjnteht be specified in the
 general  jpermit and shall require :the      ?
; submission of information necessary for
    adequate program implementation,
    including at a mhiimum; the legalname
   ,. Wd address of the owner or operator,
   ; the facility name and address, type of ',-.
    facility or discharges,.and.the receiving
    stream(s); This provision specifies
   ..minimum NQI requirements. General
   : permits may require that additional
    information be: reported in NOIs where
    appropriate, "  •-:   ;  -  ; :  , ; ..' .'•,-..    /..
     .The NOI provisions of this rule allow
    the Director to, establish alternative ;
    notice .of intent requu-ements- for general
    permitsrfor storm water discharges    '
    associated with ;indijistrial  activity from
   .inactive mining, inactive oil and gas
   operations, or inactive landfills
   ; oceiirring on-Federal lands where ah T -
   operator cannot be identified. The
   Agency is ctuTently'develbping general
   permits for storm water discharges from
   inactive mines, inactive oil and gas
   operations and inactive landfills
   occurring on Federal lands. During the
   process of developing and issuing these
   permits, EPA will work with authorized
   NPDES States to determine appropriate
   NOI requirements  for these permits     '
   given the. unique nature, distribution,  •
   and occurrence of  these discharges.  •   '
    Today's rule also provides that
 -  general permits requirihg,the submittal
   of NOIs shall specify .deadlines for !-
   submitting notices  of intent and the
   date(s) when a discharger is authorized
   to discharge under the permit.
 ^ The Agency believes that deadlines
  for submittal of an NOI are  an important
 .part of NOI requirements, and that
  general permits should state when NOIs
  must be submitted.  In addition, the
  permit should clarify when a discharge
  is authorized under the permit. In many
  .cases, the Agency anticipates that   .
  general permits will ajovide that a
  discharger obtains coverage under the
  general permit after a "specified time
 -period passes after the date  of submittal
  of an NOI. This approach will provide
  the NPDES authority with an  -     :
  opportunity to review the NOI prior to
  the authorizatjon of the, discharge. In
.Other situations, it may be appropriate
 -for general peiinits to provide that a
 discharge is authorized as soon as a
.complete and timely NQI is received.  "  '.;
   The August 16,1991 notice proposed
; in,4Q GFR i2Z28(b)C2)(iii) that unless a
 general permit provided alternative time
 periods, an NOI was to  be submitted 60
 days before the date of intended.permit
 coverage. The lanal.ruleaihends this
 paragraph such that ho default deadline .
 for submission is specified. Rather, the
 deadline for NOJ submission will be
•established on a permit-specific basis^
 Today's rule simply requiresi that this
 issiiebi .addressed in the,,generalpermit
    but leaves the permitting authority this "
    decision of which approach is most
    appropriate. The approach in the final
    rule will avoid the confusion that arose
    with the proposed regulatory language
    Used.in the August 16,1991 notice.
    Today's rule also requires that NPDES
    general permits shall specify whether a
   ; discharger that has submitted a,  . ;
    complete, and timely notice of intent to
    be coveredin accordance With the
    general permit and that is eligible for
    coverage under the permit, is authorized
    to discharge either in accordance with
  ...the permit upon receipt of the notice of
    intent by the Director, after a waiting
    period specified in the general permit,
    on a date, sjpecified in the general permit,
    or upon receipt of notification of   '
    inclusion by the Director. EPA has
    rewritten the proposed lahguage in 40
   CFR,122.28(b)(2)(iv) to make this
   provision clearer, but has not changed
   its intent. The Agency believes that the
   approach taken in the final rule retains "
   the flexibility of the proposal while
   accomplishing the same purpose.
     The Agency is finalizing this ;
 ,'regulatory framework for NOIs with
   NPDES general permits to encourage the
   use of general permits, to provide for
  , more cpnsistent NOI requirements, and
   to ensure that dischargers covered by
 ,; general permits provide appropriate
   information. Further, the Agency
   believes that today's regulatory   ,  .
   framework provides a regulatory
  framework that is consistent with
  existing practices of EPA and authorized
  NPDES States.      '

  'Si.Response to Comments
    Most commenters, addressing the
  proposed framework for NOls supported
  the concept as a useful tool forthe  •
  NPOES program. Some' of these
  commenters urged EPA to use NOIs as a
  tool to minimize burdens on the
  authority issuing permits and reduce
  costs relatiye.to submitting individual
  permit applications. Commenters    ,
  indicated that an additional reason for
  using NOIs was to assist in clarifying
  whether a facility was covered by a
 given general permit
  . The Agency agrees with these   .   •
 comments. NOIs serve.a number of
 functions. NQI requirements in general
 permits can establish a clear accounting
 of the number of permittees covered by
 the'general permit, the nature of
 operations at the facility generalUng the .:
 discharge, and theu-identity, location
 and receiving waters. NOIs nan be used
 to develop a data base of facility-
 specific information. NQIs can be used
 as,a screening tool to ideniify discharges
.where individual permits are         • :

-------
appropriate. For example, the
Identification of discharges to receiving
waters with impaired water quality can
bo used to target facilities for priority
permitting efforts. Also, the NOI can be
used to identify classes of discharges
appropriate for more specific general
permits covering a more limited set of
discharges. The NOI can provide
Information needed by the Director to
notify dischargers that a more specific
general permit was issued. The NOI also
can identify the permittee to provide a
basis to develop and implement
enforcement and compliance monitoring
strategies and priorities. In addition, the
administrative burdens on the
permitling issuing agency and the costs
to dischargers can be reduced by
replacing more complicated permit
application requirements with simplified
requirements.
   One State commented that EPA
should not mandate by regulation the
information required in an NOI, which it '
believed should be left to the State or
EPA Region issuing a general permit.  In
response, the Agency believes that
 today's regulatory framework provides
sufficient flexibility for developing NOI
requirements, and that the minimum
 Information requirements of today's rule
 represent essential information
 necessary for meeting the program
 objectives outlined above. Under
 today's rule, the minimum requirements
 for NOIs Include the legal name of the
 owner or operator and the facility name
 and address. EPA believes that this
 Information is essential to identify the
 location of the facility for compliance
 purposes and to provide mailing
 addresses necessary to conduct any
 correspondence. The minimum NOI
 requirements also include a description
 of the type  of facility or dischargers.
 This description is necessary to provide
-  information to screen whether the
  discharge is eligible for coverage under
  the general permit and to allow the
  permit writer to begin to identify priority
  discharges. Finally, the minimum NOI
  requirements include the receiving
  siream(s). This information is necessary
  to adequately identify the discharges to
  Impaired receiving waters where water
  quality-based permits are necessary.
    Some commenters indicated that they
  believed that all discharges should be
  required to submit an NOI. Various
  reasons were provided to support this
  approach. Including that the NPDES
  authority needed to know of all facilities
  that discharged storm water to a given
  water body, and that dischargers should
  not be required to comply with a permit
  unless they submit a notification. In
  response, the Agency believes that most
general permits will require the
submittal of NOI. However, there may
be some situations where it may be
more appropriate to have the Director
notify dischargers that they are covered
by a general permit or that NOI
requirements are otherwise not
appropriate.
For example, issuing a general permit
without NOI requirements  may be an
 appropriate way for EPA and authorized
 NPDES States to minimize
 administrative burdens and compliance
 costs in permits for small discharges
 which have been determined to have '
 minimal or no impacts on receiving
 waters. Today's regulation provide some
 flexibility to address these situations.  •
   In .the August 16,1991 notice, EPA
 requested comment on whether it is
 appropriate to require NOIs  for the large
 number of contaminated storm water
 discharges associated with industrial
 activity from oil and gas exploration and
• production operations. Most
 commeiiters On this issue indicated that
 they thought NOIs should be required in
 general permits for storm water
 discharges from oil and gas  operations.
 One State commented that it believed
 that it would be inappropriate to
 exclude a class of discharges from the '
 requirements to submit an NOI unless
 there  is an alternative method that can
 and will be used to track these      •   •
  discharges. A different commehter
  indicated that oil and gas operations
  were  adequately monitored through the
  Spill Prevention Control and
  Countermeasure (SPCC) program and
  that NOIs for NPDES general permits   .
  would not be necessary. A number of
  the commenters expressed confusion
  over the relationship between this
  provision and section 402(1)(2) of the
  CWA10, and suggested that requiring
    10 Section 402(1)(2) of the CWA provides that
  NPDES permits shall not be required for storm
  water runoff from mining operations or oil and gas
  exploration, production, processing or treatment
  operations or transmission facilities, composed
  entirely of flows which are from conveyances or
  systems of conveyances (including but not limited
  to pipes, conduits, ditches, and channels) used for
  collecting and conveying precipitation runoff and
  which are not contaminated by contact with or that
  •has not come into contact with, any overburden,
  raw material, intermediate products, finished
  product, byproduct or waste products located on the
  site of such operation. EPA published permit
  application regulations consistent with section
  402(1)(2) on November 18,1990 (55 FR 480030).
  These regulations require permit applications for
   discharges composed entirely of storm water
   associated with industrial activity from oil or gas
   exploration, production, processing, or treatment
   operations, or transmission facilities only when a
   discharge of storm waters results in a discharge of a
   reportable quantity for which notification is or was
   required pursuant to 40 CFR 117.21,40 CFR 302.6, or
   40 CFR 110.6 at anytime since November 16,1987, or
   the discharge contributes to a violation of a water
NOIs in NPDES permits for storm water
discharges from oil and gas operations
would minimize this confusion.
  After evaluation of the comments,
EPA believes, that except for the
situation of inactive oil and gas
operations on Federal lands  discussed
below, it is not appropriate tq exclude
contaminated storm water discharges
associated with industrial activity from
oil and gas exploration and production
operations from the minimum NOI
requirements, and therefore  today's rule
does not treat storm water discharges
associated with industrial activity from
oil and gas operations differently than
other storm water discharges associated
with industrial activity in this regard. As
a result, today's rule does not contain a
specific reference to storm water
discharges from oil and gas  operations.
The Agency believes that NOI
requirements in general permits for
storm water discharges from oil and gas
 operation will provide for a clear
 tracking mechanism that is  currently
 unavailable under the SPCC program ".
 In addition, as was pointed out by
 commenters, the  NOI process can be
 used to identify facilities with
 contaminated runoff, and therefore
 minimize confusion with respect to the
 provisions of section 402(1) [2) of the
 CWA.    "..-.-
   One commenter requested
 clarification on the procedures-that
 would be followed to ensure that
 permits requiring Director notification
 instead of facility submission of an NOI
 are in compliance with the  procedural
 requirements of the CWA and the
 NPDES regulations, The Agency does  „
 not believe that today's rule conflicts
 'with the NPDES regulations or the
  CWA. The Agency believes that the
  existing NPDES  regulations provide for
  adequate public notice and public-
  comment opportunities when general
  permits are issued. (See 40 CFR 124.10,
  quality standard, (see 40 CFR 122.26(c)(l)(iii)).
  Permit applications are not required for a discharge
  composed entirely of storm water from a mining
  operation unless the discharge comes into contact
  with any overburden, raw material, intermediate
  products, finished product, byproduct, or waste
  products located on the site of such operations..
    ".EPA requested comment on using information
 , collected under the SPCC program to track storm
  water, discharges. However, this approach has a
  number of limitations, including that the SPCC
  program currently does not require facilities subject
  to SPCC requirements to submit notifications. In
  addition, many facilities subject to the SPCC
  program are not subject to the NPDES storm water
  program either because they do not have a storm
  water discharge to waters of the United States or <
  because they are not activities (hat are addressed, .
  by the regulatory definition of storm w£ter
  ' discharge associated with industrial activity at 40
  CFR 122.26(b)(14) (e.g., certain pipelines).

-------
   124.11, and 124.57.) The Agency wants to
   point out that the NPDES regulations
   require certain opportunities for the
   public to .comment during the permit
   issuance process, and provide for permit
   appeal after the permit is issued. In
   addition, 40'CFR 122.28(b)(2)(iii)
  provides that for EPA issued permits,
   any owner or operator authorized by a
  general permit may request to be
  excluded from the coverage of the
 _ general permit by applying for an
  individual permit
    One commenter requested
  clarification on the type of notification
  that must be provided by the Director to
  a discharger where the discharger is not
  required to submit an NOI. In response,
  the Agency believes that in most cases, '
 •the Director will notify dischargers of
  coverage in writing. -
    One-commenter requested
  clarification on whether a discharger
  that is not required to submit an NOI,
  but rather is notified by a Director, will .
  be subject to permit fees. The Agency
  wants to clarify that this rulemaking
  does not address permit fees.
    One commenter, while supporting the
  requirement that an NOI be submitted,
  indicated that EPA could reduce its
  paperwork load by issuing general
 permits for storm water discharges from
 construction sites that required
 dischargers to notify municipalities
 instead of the NPDES permit authority.
 EPA disagrees with this approach.
 Submitting NOIs to municipalities but
 not requiring that an NOI be submitted
 to the Director may not assure that EPA
 or authorized NPDES States receive
 adequate information to effectively
 implement the NPDES program for these
 discharges.
   In the August 16,1991 notice, EPA
 proposed that general permits for storm
 water discharges associated with
 industrial activity from inactive mining,
 inactive oil and gas operations occurring
 on Federal lands where an operator
 cannot be identified may contain
 alternative notice of intent
 requirements. A federal land
 management agency commented that
 inactive landfills on Federal lands are in
 some ways analogous to inactive mines
 and inactive oil and gas operations and
 should be treated similarly ."EPA agrees
 with this comment and accordingly
 today's rule allows alternative notice of
 intent requirements in general permits
 for storm water discharges associated'
with industrial activity from inactive
landfills pn Federal lands.
  One State urged EPA not to refer to
NOIs as permit applications. They were
concerned that calling NOIs permit
applications would trigger certain public
notice requirements under-State law.
   They further argued that the purpose of
   NOIs are significantly different than
   permit applications, and that the cited
   State law provision should not apply". In
   response, EPA recognizes the
   differences between the purpose of a
   notice of intent and an individual permit
   application. Individual permit  -
   applications contain a significant
   amount of site-specific information that
   is typically used for the development of
   individual permit conditions. NOIs
   typically contain only general
   information and are used for screening
   and compliance purposes rather than for
  the development of permit conditions.
  However, the distinction between
  individual applications and NOIs as
  they relate to public notice requirements
  in various State laws is a question of
  interpretation of those State laws which
  EPA does not attempt to answer in this
  notice. EPA notes however, that it
  considers submission of an NOI to
  constitute a permit application for
  purposes of federal regulatory
  provisions which provide that a timely
  reapplication of a federal permit or
  license continues the effectiveness of
  the existing permit pending action by
  the Director.  (See 40 CFR 122.6).
    In the preamble to the August 16,1991
  notice, EPA discussed public
  accessibility  to  lists of NOIs, but did not
  publish proposed regulatory language
  addressing this  issue. EPA does not
  intend to address this issue in this
  rulemaking, but will be addressing the
  issue in future rulemakings.

 EPA requested comments on extending
 the deadline for submitting part 2 of the

   November 5,1991 proposal to extend the
   regulatory deadline for submitting part 2
   of the group application supported an
   extension. A number of reasons were
   provided to justify the extension,
   including the difficulty associated with
   sampling storm water discharges from
   facilities located in arid and northern
   regions during winter months, the need
   for time to allow for the preparation of
   guidance documents, training personnel
   in sampling techniques, and conducting
   analytical work. A number of
  commenters supported October 1,1992
  as the deadline for part 2 of the group
  application. In general, these
  commenters expressed their belief that
  the deadlines for submitting part 2 of the
  group application and individual permit
  applications for storm water discharges
  associated with industrial activity
  should be the same. A number of
  reasons were given for supporting this
  approach, including,.that this would be
  the most equitable approach,  the
  regulated community would have a
  clearer choice of application options,   ,
  and one deadline would limit confusion.
  EPA agrees with these concerns, and as
  is discussed above, is extending the
  deadline for submitting part 2 of the
  group application from May 18,1992 to
  October 1,1992.
   Some commenters favored extending
  the deadline for submitting part 2 of the
 group application beyond October 1,
 1992. Some of these commenters
 suggested that part 2 of the group
 application should not be required until
 general permits for storm water
 discharges associated with industrial
 activity were issued. These commenters
 indicated that this approach would
 ensure that dischargers would have
 three options for applying for a permit,
 (e,g. participating in a group application,
 submitting an individual application, or
 submitting an NOI to be covered under a
.general permit). This would allow
 dischargers to selectthe most cost-
 effective approach allowable under the
 NPDES regulatory framework. Other
 commenters suggested that participants
 in a group should be given one  complete
 year from the date gfter the group

Federal Register /Vol.  57. No. 64 / Thursday/April 2. 1992 / Rules and Regulations
receives notice of approval of the part 1
application.
  EPA notes that the extension to
October 1,1992 provides authorized
NPDES States with additional time to
issue general permits for storm water
discharges associated with industrial
activity. On August 16,1991, (56 FR
40948), EPA published a proposal
requesting public comment on draft
general permits for storm water
discharges associated with industrial
activity in States and territories without
authorized NPDES programs.12 The
Agency intends  to make every effort to
iasuo these general permits in the spring
of 1992.
  However, EPA has decided against
basing the deadline for submitting part 2
of the group applications on the date
that general permits are issued by
individual States because of the
potential confusion and uncertainty that
would arise. Although the Agency
proposed draft general permits for storm
water discharges in States without
authorised State NPDES programs in
one notice, it may not finalize all of
 these permits on the same date. The
 Agency expects that various region-
 specific. State-specific, or industrial
 category-specific issues may take
 different amounts of time to address. It
 should also be noted that the August 16,
 1991 proposal does not address general
 permits In authorized NPDES States.
 Each authorized NPDES State that will
 issue general permits for storm water
 discharges associated with industrial   .
 activity will have to go through the
 procedures for issuing general permits of
 that Stale. Different permit issuance
 procedures, along with other factors,
 will result in these permits being issued
 at different times. All of these factors
 Indicate that a  tremendous amount of
 uncertainty and confusion would result
 if EPA attempted to tie regulatory
 deadlines for submitting permit
 applications to the  dates when general
 permits  are issued for particular States.
 This is particularly important to the
 group application process where
 facilities from many different States
 may be in the same group.
    In addition, the Agency anticipates
 that there will  be situations where the.
 permitting authority determines that
    " The notice addreiics draft general permits in
  M SUtal (MA, MB. NH. PL. LA. TX, OK. NM. SD,
  AZ, AK, ID). and alx Territories (District of
  Columbia, the Commonwealth of Puerto Rico,
  Guam. American Samoa, the Commonwealth of the
  Northern Mariana Islands, and the Trust Territory
  of the Pacific Islands) without authorized NPDES
  Stale prearwns: on Indian lands In AL, CA, GA, KY,
  Ml, MN, MS. MT, NC. ND, NY, NV. SC, TN, UT, Wl.
  and WY: touted within federal facilities and Indian
  l«ndt In CO »nd WA: and located within federal
  hciUtlei in Delaware.
                           general permits are inappropriate for a
                           given class of storm water discharges.
                           Additional confusion would arise in
                           these situations if application deadlines
                           were tied to the dates of general permit
                           issuance. The Agency is also concerned
                           that unacceptable delays may result
                           under this approach in States where the
                           issuance of a general permit is delayed.
                             EPA also disagrees with the
                           suggestion that the deadlines for
                           submitting part 2 of the application
                           should be based on the date on which a
                           part \ application is accepted. EPA
                           believes that establishing a fixed
                           deadline of October 1,1992 for part 2. of
                           the group application is warranted for
                           the same reasons that the Agency
                           articulated above and in the proposal.
                           This approach provides an equitable
                           deadline for these facilities, reduces
                           confusion and uncertainty in the
                           regulated community, and provides
                           sufficient time to complete the sampling
                           necessary to obtain quantitative data.

                           E. Clarification for Part 2 of Group
                           Applications
                              The November 16,1990 regulations
                            established procedures for group
                            applications for storm water discharges
                            associated with industrial activity. The
                            group application process allows for
                            facilities'with similar storm water
                            discharges to file a single two part
                            permit application. Part 1 of a group
                            application includes a list of the
                            facilities applying, a narrative
                            description summarizing the industrial
                            activities of participants of the group, a
                            list of significant materials exposed to
                            precipitation that are stored by
                            participants and material management
                            practices employed to diminish-contact
                            of these materials by precipitation (see
                            40  CFR 122.26(c)(2)(i)). In addition, the
                            part 1 application must identify the
                            group participants that will  submit
                            quantitative data (sampling data) in part
                            2 of the group application. These
                            participants must be representative of
                            the group.
                               In part 2 of the group application, the
                             subset of facilities identified in the Part
                             1 application must submit quantitative
                             data. The provisions of 40 CFR-
                             122.26(c)(2)(ii) establish a minimum
                             criteria for identifying facilities^from
                             which sampling data must be submitted.
                             EPA had proposed that, in general,
                             groups submit data from at least 10
                             percent of the facilities in the group,
                             with a minimum of 10 facilities
                             submitting data (December 7,1988 (53
                             FR 49435)). In the final rule, EPA
                             allowed groups of 4 to 10 members to
                             apply if 50 percent of the facilities
submitted data (November 16,1990 (55
FR 48067)).        "      -     .
  During the grpup application process,
the regulated community exhibited some
confusion regarding the minimum
number of facilities that must submit
sampling data for groups with 11 to 99
members. For groups with 11 to 99
members, some groups have interpreted
the language  in the November 16,1990
regulations to require 10 percent of the
facilities to submit sampling data, while ,
other groups  have interpreted the
language to require a minimum of 10
facilities to submit sampling data.
  In today's action, EPA wants  to clarify
that for groups with 20 or fewer
members, at  least 50 percent of the
dischargers participating in the  group
must submit  quantitative data. For
example, at least nine facilities must
submit quantitative data if a group is
composed of 17 members. For groups
with 21 to 99 members, at least  10
dischargers participating in the group
must submit quantitative data. For
 example, at least ten facilities must
 submit quantitative  data if a group is
 composed of 25 members. For groups
 with 100 to 1,000 members, at least 10
 percent of the dischargers participating
 in the group must submit quantitative
 data. For groups with more than 1,000
 members, no more than 100' dischargers
 participating in the group must submit ,
 quantitative data. •   .
   For groups with more than 10
 members, either a minimum of two
 dischargers  from each precipitation zone
 indicated in appendix E of 40 CFR part
 122 in which ten or more members of the
 group are located, or one discharger
 from each precipitation zone indicated
 in appendix E of 40 CFR part 122 in
 which nine  or fewer members of the
 group are located, must be identified to
 submit quantitative data. For groups of 4
 to 10 members, at least one facility in
 each precipitation zone in which
 members of the group are located must
 submit data. EPA has made a correction
 to the group application requirements to
 reflect the above, which represents
 EPA's original intent in the November
  16,1990 rule.      •„_•"'.
 F. Transportation Act Deadlines
    Section 1068 of the Transportation Act
  addresses permit application deadlines
  for storm water discharges associated
  with industrial activity that are owned
  or operated by municipalities. Today's
  rule codifies three changes to  existing
  regulatory deadlines to reflect the new
  provisions  of section 1068. The first two
  modifications address individual
  application deadlines, and the third
  addresses group application deadlines.

 the regulatory application deadlines fot
 storm water discharges associated with
 industrial activity from facilities that are
 either not owned or operated by a
     municipality or that are owned or
     operated by a municipality with a
     Copulation of 250,000 or more. The

    .the dates established in EPA's           ;

    H11509 (daily ed. November 26,1991)
    Rep. yammerschmidt). Thus, the permit
    application deadlines for storm water
    discharges associated with.industrial
  ,  activity from-privately owned and
  '.operated facilities, including those that
    discharge through a municipal separate
  • :stOrm sewer to waters of the United
   States, are not changed by today's rule
   with the exception of the part 2         ;
   application deadlines discussed

   a facility is pHvately owned and

   with, a municipality, tljejKcjlity is not
   considered to be "municipally
   operated". For example, a privately  :
  owned and operated landfill that
  receives municipal waste pursuant to a
  .contract with a municipality or some ' =:   '
  other form, of,reimbursement"from a
  .municipality can not avail itsetf of th^
  application deadline extensions in the
  Transportation Act, which apply only to
  racihties owned or operated by
  municipal governments.   :      . .
  ., As outlined above, section 1060 of the
  IransportatioriAct contains special   '
  provisions for municipalities'with a       ;
 ;po^fetion,pf less than 100,000. Section   :
-^068(c) of the IS-ansportationAct         '
.defmes;two classes of industrial  -
 tacihties that are owned or operated by
 municipalities with a population of less  .•
 than: 100,000. The first group of facilities
 is comprised'oi airports, powerplants,
 and uncontrolled sanitary landfills that
-are owned  or operated by a municipality
 with a population of less than 100,000. It
 is clear that Congress did not intend in
 section I068fc) to change the existing
individual application deadlines for
these discharges. Group application
requirements for storm water discharges
associated with industrial activity from
•InRnfM80^!!88  are addressed by section
1068(b) of the Transportation Bill. As
discussed above, the group application
deadlines for these facilities are May 18,
1992 for Part 1 applicaitons and May 17
  £1for Part-2 applications".
  The second group is comprised of
facilities with storm water discharges
associated with industrial activity other
    . than airports, powerplants or
     uncontrolled: sanitary landfills that are
    ,owned,or operated by municipalities
     with a population:of lessjthan 100,000
     Section 1068(c) pro.vides that EPA shall
     not require this second group of
    .industrial facilities to apply for or,obtain
     a permit before October 1,1992,-unless a
    permit is required under either-section
    402(p)(2) (A)or(E)of theCWA. T
    _ With respect to this second group of
    tacilities, today's rule reserves the
    regulatory deadlines for storm water
    applications. The Agency intends to
    address these facUities in a manner that
    is similar to other storm water
    discharges addressed by section
    402(p)(l) or the CWA.« Currently, the  -
    Agency intends ;to evaluate storm water
    discharges associated withT industrial
    activity that are owned or operated by a
    municipality with a population of less
    than 100,000 (except for those from
    powerplants, uncontrolled:sanitary
    landfills and airports) along with other
    storm,water discharges addressed by     '
    section 402(p)(l)'iij;two' studies req'uired
   under sectiori402(p)(5) of the CWA.
   These studies-willbe used to  support   "
   the development of regulations under
   section 402(p)(6)." it is clear from the
   legislative history of the Transportation
   Act that Congress intended to address
   these discharges in this manner, i.e., as
   discharges subject to the permit    '
   moratorium of section 402(p)(i) Of the
   CWA. "EPA defined industrial activity v
   in^such a Way as to require many cities

1. Determining the Population of
Municipalities
  The Transportation Act establishes
phased requirements for NPDES permits
for storm water discharges associated
with industrial activity from facilities
that are owned or operated by
municipalities with specified
populations. However, the
Transportation Act uses a different
classification scheme than is used in
section 402(p) of the CWA to define
classes of municipal separate storm
sewer systems. Under section 402(p) of
the CWA, municipal separate storm
sewer systems are classified  on the
basis  of population  served by the
system. Under the Transportation Act,
the population used for classifying
industrial operations owned or operated
by municipalities is the population of the
 municipality. This distinction is
 important because a number of
 municipal entities with a population of
 100,000 or more are not addressed by the
 regulatory  definitions of large and
 medium municipal separate storm sewer
 systems.
   40 CFR 122.26(b)(4) and (7) specifically
 Identify 173 cities and 47 counties as
 having large or medium municipal
 separate storm sewer systems (e.g.
 systems serving a population of 100,000
 or more).18 While these definitions
 identify all incorporated cities with a
 population of 100,000 or more, they only
 specifically identify 47 of the 447
 counties with a population of 100,000 or
 more based on the  1990 Census.16 In
 addition, other types of municipal
 entities which may own or operate
 storm water discharges associated with
 industrial  activity are not specifically
 addressed by the regulatory definition of
 large and medium municipal separate
 storm sewer systems. Examples include;
 sanitary sewer districts, flood control
  districts, and unincorporated towns and
  townships.
    In providing phased requirements for
  different storm water discharges
  associated with industrial activity that
  are owned or operated by
  municipalities, EPA believes that a
primary concern of Congress was the
economic burdens placed on
municipalities with a smaller population
base over which to spread costs. In
general, when determining the
population of a municipal entity, EPA
will look at the general population or
service population of Ihe municipal
entity.                '   .
  For the purpose of today's rule, the   .
1990 Census will be  used to determine
the population of counties. Service
populations will be used to determine
the population of sewage treatment
districts which operate publicly owned
treatment works (POTWs). Where one
sewer district operates a number of
plants, the entire service population of
the district will be used to determine the
applicable population classification of
'all of the treatment works operated by
the district.17 Populations within service
districts will be used to determine the
populations of flood control districts and
other municipal entities with service .
populations. The State population will
be used to determine the population of
State DOTs.l B Where an industrial
facility is owned or operated by more
 than one municipality, then EPA intends
 to use the combined populations of the
 appropriate municipalities in
 determining population thresholds.
   EPA believes that the distinction
 between the population of a   ,
 municipality and the population served
 by a municipal separate storm sewer
 system is appropriate and was intended
 by Congress. In  the November 16,1990
 rulemaking, EPA noted inter-jurisdiction
 complexities associated with municipal
 governments developing controls for
 storm water into such large and medium
 systems played a role in defining the
 regulatory terms large and medium
 municipal separate storm sewer
 systems. However, such concerns do not
 appear to be as evident with industrial
 facilities that are owned or operated by
 municipal entities.

  analyses of major regulations. Major
  regulations are those which impose a
  cost on the economy of $100 million or
  more annually or have certain other
  ecpnomic impacts. Today's regulatory
  amendments generally make the NPDES
  permit applications more flexible and
  less burdensome for the regulated

  activity from facilities owned or   ,

  adopted without notice and comment
 .-As they merely codify the provisions of

 Transportation Efficiency Act of 1991,  *   '
 they constitute interpretive rules for
 which notice and comment is not  '
 required. :EPA requested comment  on
 the issue of the minimum number of
 facilities that must submit sampling data
 in a group application in a December 7
 1988 notice (53 FR 49416). Additional
 notice and comment is. not required for
 the clarification to the group application
 regulations made in today's rule because
the Agency has already taken comments
on this issue.and today's action only
clarifies the approach that was intended
by the November I6i 1990 rule.
