1.0 STORM WATER PROGRAM
1.1 BACKGROUND
The 1972 amendments to the Federal Water Pollution Control Act (FWPCA, also referred to as the
Clean Water Act or CWA) prohibit the discharge of any pollutant to waters of the United States
from a point source unless the discharge is authorized by a National Pollutant Discharge
Elimination System (NPDES) permit. Efforts to improve water quality under the NPDES program'
traditionally have focused on reducing pollutants in discharges of industrial process wastewater
and from municipal sewage treatment plants. Past efforts to address storm water discharges under
the NPDES program have generally been limited to certain industrial categories with effluent lirni-
, tations for storm water. _ ,.
In response to the need for comprehensive NPDES requirements for discharges of storm water,
Congress amended the CWA in 1987 to require the Environmental Protection Agency (EPA) to
establish phased NPDES requirements for storm water discharges. To implement these require-
ments, EPA published the initial permit application requirements for certain categories of storm
water discharges associated with industrial activity and for discharges from municipal separate
storm sewer systems .located in municipalities with a population of 100,000 or more (Phase I
sources) on November 16, 1990 (55 FR 47990). Storm water discharge permits provide a mecha-
nism for monitoring the discharge of pollutants from Phase I sources to waters of the United States
and for establishing appropriate controls. In addition, EPA promulgated a final rule addressing
Phase II sources on August 7, 1995 (60 FR 40230). These requirements are described in more
detail below. , ' ' ' . • ,
1.2 ENVIRONMENTAL IMPACTS
Pollutants in storm water discharges continue to remain a significant source of environmental
— impacts to the quality of waters of the United States. The "National Water .Quality Inventory,
1994 Report to Congress" provides a general assessment of water quality based on biennial reports
submitted by the States under Section 305(b)-t>f the Clean Water Act, The Report indicates that
storm water discharges from a variety of sources including separate storm sewers, construction,
waste disposal, and resource extraction activities are major causes of water quality impairment.
Roughly 46 percent of the identified cases of water quality impairment of estuarine square miles
surveyed, for example, are attributable to storm sewer runoff. .
2.0 PHASE I PROGRAM
EPA published permit application requirements for Phase I storm water sources on November 16,
1990. Phase I sources include storm water discharges associated with industrial activities and
storm water discharges from municipal separate storm sewer systems located in municipalities
serving a population of 100,000 or more. The following describes, in more detail, the types of dis-
charges covered by the Storm Water Phase I Program and the application options for these dis-
charges.
2.1 INDUSTRIAL FACILITIES COVERED
EPA has defined the term "storm water discharge associated with industrial activity" in a compre-
hensive manner to address over 100,000 facilities (see Attachment I for a complete definition).
All storm water discharges associated.< with industrial activity that discharge through municipal
separate storm sewer systems or that discharge directly to waters of the United States are required
May, 1996
-------
Overview of the Storm Water Program
to obtain NPDES permit coverage, including those which discharge through systems located in
municipalities with a population of less than 100,000. Discharges of storm water to a sanitary
sewer system or to a Publicly Owned Treatment Works (POTW) are excluded'. Facilities with
storm water discharges associated with industrial activity include: manufacturing facilities; con-
struction operations disturbing five or more acres; hazardous waste treatment, storage, or disposal
facilities; landfills; certain sewage treatment plants; recycling facilities; powerplants; mining oper-
ations; some oil and gas operations; airports; and certain other transportation facilities. Operators
of industrial facilities that are Federally, State or municipally owned or operated that meet the
description of the facilities listed in 40 CFR 122.26(bj(14)(i)-(xi) must also submit applications
(note: the Transportation Act of 1991, described below, provides exceptions for certain municipal-
ly owned or operated facilities). EPA published final rules regarding the NPDES Storm Water
Regulations on both April 2, 1992 (57 FR 11394) and December 18, 1992 (57 FR 60444). The
rule promulgated on April 2, 1992 was, in part, to codify provisions of Transportation Act of 1991.
The December 18, 1992 rule was in response to the mandate of the Ninth Circuit Court in Natural
Resources Defense Council (NRDC) v. EPA (June 4, 1992). Each of these final rules are summa-
rized below.
TRANSPORTATION ACT OF 1991
The Transportation Act of 1991 provides an exemption from Phase I storm water permitting.
requirements for certain industrial activities owned or operated by municipalities with a popula-
tion of less than 100,000. Such municipalities must submit storm water discharge permit applica-
tions only for airports, powerplants, and uncontrolled sanitary landfills that they own or operate,
unless a permit is otherwise required by the permitting authority.
NINTH CIRCUIT COURT DECISION
The Ninth Circuit United States Court of Appeals' opinion in Natural Resources Defense Council
(NRDC) v. EPA (June 4, 1992) and the opinion in American Mining Corporation (AMC) v. EPA
(May 27, 1992), affirmed and upheld the basic structure and direction of the national storm water
program.' In the NRDC case, the Court upheld the definition of "municipal separate storm sewer
system," the standards for municipal storm water controls, the scope of storm water requirements
for oil and gas operations, and EPA's decision not to provide public comment on Part 1 group
industrial permit applications. On the question of deadlines, the Court noted that the storm water
application deadlines clearly exceeded statutory requirements, but refused to "roll back" the cur-
rent regulatory deadlines. The Court also emphasized, however, that any further regulatory exten-
sion would'be illegal. In two other areas the Court invalidated and remanded for further proceed-
ings two regulatory exemptions from the definition of "storm water discharges associated with
industrial activity": (1) the exemption for construction sites disturbing less than five acres of land
(category x), and (2) the exemption of certain "light" manufacturing facilities without exposure of
materials and activities to storm water (category xi). In response to these two remands, the
Agency intends to conduct further rulemaking proceedings on construction activities under five
acres and light industry without exposure as ordered by the Court. EPA will not require permit
applications for construction sites disturbing less than five acres of land and category xi facilities
without exposure until this further rulemaking is completed. In the AMC case, the Court upheld
EPA's regulation ofstorm water discharges from inactive mines. •
2.2 INDUSTRIAL PERMIT APPLICATION OPTIONS
The November 16, 1990, storm water regulation presented three permit application options for
storm water discharges associated with industrial activity. The first option is to submit an individ-

-------

ual application consisting of Forms 1 and 2F. The second option, to participate in a group applica-
tion, is no longer, available as the deadlines have passed. The third option is to file a Notice of
Intent (NOI) to be covered under a general permit in accordance with the requirements of an
issued general permit. The following overview briefly outlines each of these three options and the
subsequent attachments provide a more detailed explanation. Attachment II lists application dead-
lines for each of the industrial permitting options.
2.2.1 INDIVIDUAL PERMIT APPLICATIONS
Operators of facilities with storm water discharges associated- with industrial activity who did not
participate in a group application or did not obtain cpverage under a general permit must submit
an individual application consisting of .Form 1 and Form 2F. The information required in Form 2F
includes a site drainage map; a narrative description of .the site identifying potential pollutant
sources, and quantitative testing data. There are specific requirements for construction activities
and oil and gas operations and mining operations. See Attachment III for additional information.
2.2.2 GROUP APPLICATIONS
The group application procedure was an option available for facilities that have similar industrial
operations, waste streams, and other characteristics. Group applications reduced the burden oh the
regulated community by requiring the submission of quantitative data from only selected members
of the group. The group application was submitted in two parts. Part 1-of the application identi-
. fied all participants, provided facility-specific information, and proposed a representative sam-
pling subgroup. Part 2 of the application consisted of sampling data from each member of the
/sampling subgroup identified in Part 1 of the application. EPA used the information provided in
Parts 1 and 2 of the group applications to develop the multi-sector general permit.
2.2.3 GENERAL PERMIT APPLICATIONS
Industrial storm water dischargers that submit an NOI to be covered by a general permit are not
required to submit an individual permit application, provided the discharger is eligible for the gen-
eral permit and an individual permit application is not required by the Director on a case-by-case
basis. Submitting an NOI is less burdensome than submitting an individual application. The NOI
requirements for general permits usually address only general information and typically do not
require the collection of monitoring data. Submittal of an NOI is only possible where applicable
general permits have been issued by the permitting authority. EPA has finalized baseline general
permits for construction and industrial activity in the 11 States without NPDES authorization (57
FR 41176, September 9, 1992 and 57 FR 44412, September 25, 1992). More,recently, EPA final-.
ized the multi-sector general permit which provides coverage' for 29 specific industries in the 11
. States without NPDES authorization (60 FR 51108, September 29, 1995). As of May 1995, all of
the 39* authorized NPDES States have general permit authority. See Attachments IV, V, VI and
VII for additional information. ,, ,
* The State of Florida became the 40th State to receive NPDES permitting authority in May 19? 5,
with phased NPDES Storm Water authority to be fully implemented by the year 2000. EPA Region
4 continues to administer the NPDES Siorm Water General Permitting Program for the State.

2.3 MUNICIPAL APPLICATIONS
"Municipal separate storm sewer" is defined as any conveyance or system of conveyances that is
owned or operated by a State or local government entity designed for collecting and conveying
storm water which is not part of a Publicly Owned Treatment Works (POTW). The application
requirements do not apply to discharges from combined sewers (systems designed as both a sani-
tary sewer and a storm sewer). Municipal separate storm sewer systems that are addressed by the
Phase I regulations (November 16, 1990) include storm sewer systems located in an incorporated
place with a population of 100,000 or more; located in 47 counties identified by EPA as having
populations over 100,000 in unincorporated, urbanized areas; and systems that are designated by
the Director based on consideration of the' location of the discharge with respect to waters of the
United States, the size of the discharge, the quantity and nature of the pollutants discharged to
waters of the United States, the interrelationship to other regulated storm sewer systems, and other
factors. The operator of a designated system should have been or will be notified by the Director.
Under the November 16, 1990, storm water rule, those municipal separate storm sewer systems
identified were required to submit a two-part application. The first part required information
regarding existing programs and the means available to the municipality to control pollutants. In
addition, part one required a field screening analysis of major outfalls to detect illicit connections.
Building on this information, the second part required a limited amount of representative quantita-
tive data and a description of a proposed storm water management plan. See Attachment II for
application deadlines and Attachment VIII for a detailed explanation of the two-part application
process.
Approximately 850 entities are participating in the Phase I Municipal Storm Water Permit
Program. This number represents large, medium, and small counties and cities and special dis-
tricts throughout the country. Several of these small counties and cities and special districts are
included in the program because they are associated with larger systems. Delegated states and
EPA Regions have already issued a number of permits covering the storm water discharges from
the municipal separate storm sewer systems operated by these entities.
3.0 PHASE II PROGRAM
On August 7, 1995, EPA promulgated application regulations for Phase II of the NPDES Storm.
Water Program. The Phase II regulations establish a sequential application process for all Phase II
storm water discharges, which include all discharges composed entirely of storm water, except
those specifically classified as Phase I dischargers. Such discharges may include storm water from
small municipal separate storm sewer systems, and commercial and institutional facilities. The
application regulations include two tiers. The first tier is for Phase II dischargers that the NPDES
permitting authority determines are contributing to a water quality impairment or are a significant
contributor of pollutants to waters of the United States. Dischargers that have been designated by
the permitting authority are required to obtain a permit and must submit a permit application with-
in 180 days of notification that an application is required.
The second tier of the Phase II storm water application regulations require all remaining Phase II
sources (i.e., all Phase II sources not designated by the permitting authority) to submit a permit
application by August 7, 2001, but only if the Phase II regulatory program in place at that time
requires permits. Currently, EPA is required by court order (NRDC v. Browner, April 6, 1995) to
propose supplemental rules for Phase II sources by September 1, 1997 and finalize these rules by
March 1, 1999. -

Overview of the Storm Water Program
EPA has established an Urban Wet Weather Flows Advisory Committee, in accordance with the
provisions of the Federal Advisory Committee Act (FACA) and the Negotiated Rulemaking Act,
to help address issues associated with water quality impacts from urban wet weather flows and
other storm water discharges under Section 402(p)(6) of the Clean Water Act. The Committee has
created several subcommittees tasked with addressing specific issues, including a Sanitary Sewer
Overflow FACA Subcommittee and a Storm Water Phase II FACA Subcommittee. The Storm
Water Phase II Subcommittee involves stakeholders, including representatives from municipali-
ties, industries, commercial and retail facilities, environmental groups, States, and Tribes, in the
Agency's effort to propose supplemental rules for Phase II sources. The Subcommittee is current-
ly in the process of developing a recommended approach for a proposed rule addressing Phase II
storm water discharges and information on the benefits and costs associated with such a proposal.

ATTACHMENT I
STORM WATER DISCHARGE ASSOCIATED WITH INDUSTRIAL ACTIVITY
The November 16, 1990 regulation defines storm water discharge associated with industrial activi-
ty as the discharge from any conveyance which is used for collecting and conveying storm water
and which 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 40 CFR Part 122. For the categories of industries identified in sub-
paragraphs (i) through (x) of this subsection, 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 40 CFR 401); 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 finished products; and areas where industrial activity has taken place in the
past and significant materials remain and are exposed to storm water. For the categories of indus-
tries identified in subparagraph (xi), the term ^includes' only storm water discharges from all the
areas (except access roads and rail lines) that are listed in the previous sentence where material
handling equipment or activities, raw materials, intermediate products, final products, waste mate-
rial, by-products, or industrial machinery are exposed to storm water. For the purposes of this
paragraph, material handling activities include the: storage, loading and unloading, transportation,
or conveyance of any raw material, intermediate product, finished product, by-product or waste
product. The term excludes areas located on plant lands separate from the plant's industrial activi-
ties, 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
tha't meet the description of the facilities listed in this paragraph (i)-(xi) include those facilities
designated under the provision of 122;26(a)(l)(v). The following table lists categories of facilities

Notes: On June 4, 1992, the U:S. Court of Appeals for the Ninth Circuit remanded the exemption
for construction sites of less than five acres and for manufacturing facilities in category (xi) which
do not have materials or activities exposed to storm water to the EPA for further rulemaking.
NRDC v. EPA, 966 F.2d 1292 (9th Cir. 1992). In response to the remands, the Agency intends to
conduct further rulemakings on both the light manufacturing and the construction activities. In the
December 18, 1992, Federal Register, EPA stated that it is not requiring permit applications from
construction activity under five acres or light industry without exposure until this further rulemak-
ing is completed.
The Transportation Act of 1991 provides an exemption from storm water permitting require-
ments for certain facilities owned or operated by municipalities with a population of less than
100,000. Such municipalities must submit storm water discharge permit applications for only air-
ports, power plants, and uncontrolled sanitary landfills that they own or operate, unless a permit is
otherwise required by the permitting authority. ,

ATTACHMENT IV
BASELINE INDUSTRIAL GENERAL PERMIT - GENERAL INFORMATION
On September 9 and 25, 1992, EPA issued baseline general permits for construction and industrial
activity (5 7 FR 41176 and 44412) which are intended to initially cover the majority of storm water
discharges associated with industrial activity in 11 States and 6 territories without authorized
NPDES programs. As of May 1995, all, 39"; of the authorized NPDES States have authority to
issue general permits. Facilities in authorized NPDES States should contact their State permitting
agencies to determine whether a general permit is available for their facility. This attachment out- -
lines the conditions in EPA's baseline general permit for industrial activities.
* The State of,Florida became the 40th State to receive NPDES permitting authority in May 1995,
with phased NPDES Storm Water authority to be fully implemented by the year 2000. EPA Region
4 continues to administer the NPDES Storm Water General Permitting Program for the State.

Pollution Prevention Plan Requirements .
The pollution prevention plan is considered to be the most important requirement of the general
permit. Each industrial facility covered by the baseline general permit must develop a plan, tai-
lored to the site specific conditions, and designed with the goal to control the amount of pollutants
in storm water discharges from the site.
Pollution Prevention Team
Each facility must select a pollution prevention team of one or more individuals from its staff.
This team will be responsible for the development and implementation of the plan.
Components of the Plan
- ! - . \ - ' • .
The permit requires that the plan contain a description of potential pollutant sources and a
description of the measures and controls to prevent or minimize pollution of storm water.
A The description of potential pollutant sources must include:
- A map of the facility indicating the areas which drain to each storm water discharge point
- An indication of the industrial activities which occur in each drainage area
- A prediction of the pollutants which are likely to be present in the storm water
- A description of the likely sources of pollutants from the site
-. An inventory of materials that may be exposed to storm water
- The history of spills and leaks of toxic or hazardous materials for the last three years.
A The measures and controls tp-prevent or minimize pollution of storm water must include:
. - Good housekeeping or upkeep of industrial areas exposed to storm water
- Preventative maintenance of storm water controls and other facility equipment
- Spill prevention and response procedures to minimize the potential for and the impact
. of spills .-.'"-

ATTACHMENT V
BASELINE CONSTRUCTION GENERAL PERMIT-GENERAL INFORMATION
On September 9 and 25, 1992, EPA issued baseline general permits for construction and industrial
activity (57 FR 41176 and 44412) which are intended to initially cover the majority of storm water
discharges associated with industrial activity in 11 States and 6 territories without authorized
NPDES programs. As of May 1995, all 39* of the authorized NPDES States have authority to
issue general, permits. Facilities in authorized NPDES States should contact their State permitting
agencies to determine the whether a,general permit is available for their facility.. This attachment
outlines the conditions in EPA's baseline general permit for construction activities.
* The State of Florida became the 40th State to receive NPDES permitting authority in May 1995,

Pollution Prevention Plan Requirements
A Operators of all activities covered by EPA's baseline general permits must prepare and
implement a storm water pollution prevention plan.
Pollution Prevention Plan Requirements for Construction Activities
The Pollution Prevention Plan is considered to be the most important requirement of the General
Permit. Each construction activity covered by the baseline general permit must develop a plan,
tailored to the site specific conditions, and designed with the goal to control the amount of pollu-
tants in storm water discharges from the site.
A Components of. the Plan—The permit requires that the plan contain a site description, and
a description of the measures and controls to prevent or minimize the pollutants in storm
water. The site description must include: . .
- -A description of the nature of the construction activity
- . A sequence of major construction activities .
- An estimate of the total area of the site and of the area .to be disturbed .
- An estimate of the runoff coefficient of the site after construction is complete
- Any existing data on the quality of storm water discharge from the site
- The name of the receiving water
- Any information on the type of soils.at the site; and
- A site map indicating the drainage patterns and slopes after grading activities are complete,
areas of soil disturbance, the outline of the area to be disturbed, the locations of stabilization
measures and controls, and surface waters at the discharge points.
A Measures and Controls—Measures and controls to prevent or minimize pollution of storm
water must include three different types of controls: erosion and sediment controls, storm
water management controls, and other controls.
Erosion and Sediment Controls .
- Stabilization (seeding, mulching, etc.) — Disturbed area where construction has permanently
or temporarily ceased must be stabilized within 14 days of the last disturbance or as soon as
practicable in semi-arid and arid areas (areas which will be redisturbed within 21 days do not
have to be stabilized).
May, 1996 , . ' V-3
-------
Overview of the Storm Water Program
- Structural Controls — Sites with common drainage locations that serve ten or more disturbed
acres must install a sediment basin where it is attainable (where a basin is not attainable, sed-
iment traps, silt fences, or other equivalent measures must be installed). Sediment basins
must provide 3,600 cubic feet of storage per acre drained. Drainage locations which serve
less than ten disturbed acres must install either a sediment basin, sediment trap, or silt,fence
along the down slope and side slope perimeter. :
- The plan shall be prepared on or before April 1, 1993 (and updated as appropriate) and
implemented by October 1, 1993. Facilities that begin construction activities after October
1, 1992 must prepare and implement their plan at the time they submit the NOI.

ments are required to incorporate additional BMPs for inspections, leak detection, spill pre-
vention, and spill clean-up and control. The pollution prevention plan is certified for these
special requirements by a responsible corporate official, not by a licensed PE, as under the,
baseline general permit. No special EPCRA 313 monitoring requirements are included in
the multi-sector general permit.
Comprehensive Site Compliance Evaluation—At least once a year, facility personnel
must conduct a site compliance evaluation. Personnel conducting the evaluation shall:
- Inspect for evidence of, or the potential for, pollutants entering the drainage system

KEY DIFFERENCES BETWEEN THE BASELINE AND MULTI-SECTOR PERMITS
The following table lists the key differences between the Baseline General Permit for Industrial
Activities and the Multi-Sector General Permit.
Baseline
Multi-Sector
Eligibility:
-Excludes discharges subject to Storm Water
Effluent Limmiation Guidelines
- Prohibits coverage of facilities which have
an adverse impact on endangered species.
- Does not exlude facilities based upon
industrial activity (except construction and
non regulated industries).
- Covers many discharges subject to Effluent
Limitation Guidelines (unless already subject
to a permit) including runoff from: phosphate
fertilizer manufacturing, asphalt emulsion
manufacturing, storage piles at cement kilns,
dewatering discharges at sand and gravel
mines, and coal piles steam electric generators.
- Prohibits coverage of facilities which have
an adverse impact on endangered species and
requires permittee to certify there will not be
impact.
- Does not cover industrial activities which
were not represented in the group application
process (e.g., drug manufacturers, petroleum
refineries, and lime manufacturers.)

Overview of the Storm Water Program
Baseline
Multi-Sector'
Storm Water Pollution Prevention Plan
- Requires consideration of ge'neric pollution
prevention measures. There are no industry-
specific or pollutarit-specific best management
practices which must be considered.
- Facilities subject to EPCRA 313 TRI
reporting requirements are required to
incorporate additional measures into their
SWPPP, and to have the plan certified by a
Professional Engineer every 3 years.
- Does not provide guidance on specific types
of BMPs which industries may utilize.
- 29 different industry sections contain
requirements to consider industry-specific,
some pollutant-specific, and generic best
management practices.
- Facilities subject to EPCRA 313 TRI
reporting requirements are required to
incorporate additional measures into their
SWPPP, however the plan only needs to be
certified by the facility operator.
- Fact sheet describes applicable BMPs for
each industry sector.
Numeric Effluent Limitations ,
- Contains numeric effluent limits only for
coal pile runoff (not at steam electric
generating facilities). Limits are based upon
BAT/BCT effluent limitation guideline for
steam electric generating industry.
- Contains BAT/BCT numeric effluent limits
taken from effluent limitation guidelines for
coal pile runoff, phosphate fertilizer ,
manufacturing runoff, asphalt emulsion
manufacturing runoff, storage pile runoff at
cement kilns, and dewatering discharges at
sand and gravel mines.

Baseline
Multi-Sector
Monitoring
- Monitoring is done for discharge
characterization.
- Requires facilities subject to EPCRA
313 TRI reporting requirements for water
priority chemicals to monitor and report
semi-annually.
- Requires 3 industries (primary metals,
land disposal and wood treaters) to monitor
and report semi-annually. Requires an
additional 12 specific industry sub-sectors
to monitor annually and retain the results
on site.
- List of parameters to be monitored for
each industry, is based upon general research
into industrial activities and significant
materials.
- Facilities may exempt themselves from
all monitoring requirements where they
can certify that there are no significant
materials or industrial activities exposed
to storm water.
- Semi-annual facilities are required to
submit data, annual monitoring facilities
retain data on site.
- No visual monitoring.
- Monitoring is designed to assess
effectiveness of the SWPPP and to provide
incentive to reduce pollution.
- Monitoring is not required as a result of
reporting status under the ECPRA 313
program.
- Requires 28 specific industry sectors
with highest risk to monitor discharges
quarterly during years 2 and 4 of permit
coverage. Facilities with pollutant
concentrations lower than benchmarks in
year 2 are exempt from monitoring in year
4.
- List of parameters to be monitored for
each industry is based upon review of
information from group applications
including; sampling data and descriptions
of industrial activity, and significant
materials.
- Facilities may exempt themselves from
monitoring on a pollutant by pollutant basis
if they can certify that there are no sources
of a pollutant present.
- All facilities that monitor are required to
submit data. Facilities are encouraged to
review monitoring results and revise the
SWPPP where pollutants are above
benchmark concentrations.
- Routine visual monitoring to assess •
problems.

ATTACHMENT VIII
MUNICIPAL APPLICATION REQUIREMENTS
The CWA requires that NPDES permits for discharges from municipal separate storm sewer sys-
tems include a requirement to effectively prohibit non-storm water discharges into the storm sew-
ers, and controls to reduce the discharge of pollutants to the maximum extent practicable (includ-
ing management practices, control techniques and system design and engineering methods, and
other provisions appropriate for the control of such pollutants). EPA or authorized NPDES States
may issue system-wide or jurisdiction-wide permits covering all discharges from a municipal sep-
arate storm sewer system. The November 1990* storm water final rule established requirements for
a two-part permit application designed to facilitate development of site specific permit conditions.
The permit application requirements provided municipal applicants an opportunity to propose
appropriate management programs to control pollutants in discharges from their municipal sys-
tems. This application process increased flexibility to develop appropriate permit conditions and
ensured input from municipalities in developing appropriate controls.
