SEPA Major Issues in Recent Regulations
Governing Storm Water Discharges
On April 2,1992 the U.S. Environmental Protection Agency
(EPA) published regulations addressing six major issues re-
lated to the National Pollutant Discharge Elimination System
(NPDES) storm water program. (See 57 FR11394.)
1. EPA s Long-Term Permitting Strategy
To regulate effectively the more than 100,000 storm water
discharges associated with industrial activity, EPA or the
authorized NPDES States first will issue Tier I baseline gen-
eral permits to regulate most of these discharges. As priorities
and risks are evaluated, Tier II through IV permitting activi-
ties will occur. Tier II permits will be issued to storm water
discharges located in degraded or sensitive watersheds. Tier
III permits will be issued for priority industiy classes, and Tier
IV individual permits will be issued for priority facilities.
The long-term permitting strategy also provides guidance for
the development of State storm water permitting plans to
provide public participation and to ensure implementation of
storm water permitting activities.
2. Minimum Monitoring and Reporting
Requirements
The rule gives permit writersadditional flexibility to establish
monitoring requirements for storm water discharges associ-
ated with industrial activity. These permit requirements will
be established case by case, witha minimum requirement that
industrial site operators inspect their facilities at least once a
year to identify pollutant sources and to certify that their
facilities are in compliance with their permits. Permit writers
continue to have the authority to require additional monitor-
ing on a case-by-case basis where appropriate.
3. Minimum Notice of Intent Requirements
The rule establishes a framework for permit writers to estab-
lish notice of intent (NOI) provisions for NPDES general
permits. Discharges use an NOI to apply for coverage under
an appropriate general permit issued by EPA or an autho-
rized NPDES State.
Dischargers apply for coverage under a general permit by
submitting a Notice of Intent (NOI). All NOIs must include,
at a minimum, the following basic information: the legal
name and address of the owner or operator of the d ischarging
facility; the name and address of the facility that discharges
the storm water; thetypeof facility or discharge; and the name
of the stream or water body that receives the discharge.
General permits may specify additional information that
applicants must include in their NOIs.
4. Part 2 Group Application Deadline
The rule extends the deadline for submitting Part 2 of
group applications from May 18,1992 to October 1,1992.
5. Clarification of How Many Facilities Must
Submit Sampling Data in Part 2 of Croup
Applications
The rule clarifies that at least 50 percent of the facilitie
participating in a group of 4 to 20 members must submi
sampling data in Part 2 of the group application. For group:
with 21 to 99 members, at least 10 participants must submi
sampling data. For groups of 100 to 1,000 members, at least ft
percent of participating facilities must submit sampling data
For groups with more than 1,000 members, no more than 10(
participants must submit sampling data.
6. Codification of Transportation Act Deadlines
The Transportation Act of 1991 established several new appli
cation deadlines for certain storm water discharges fron
industrial activity owned or operated by municipalities. EPA'
rule codifies these extensions into the NPDES regulations.
Individual permit application deadlines for municipalh
owned or operated industrial storm water discharges are tc
be submitted by October 1, 1992, with two exceptions: 1
municipal facilities that have been rejected from group appli
cations must submit individual permit applications no late;
than the 180th day following the date of the denial, and 2
facilities owned or operated by municipalities with popula
tions of less than 100,000 (excluding airports, power plants, o
uncontrolled sanitary landfills) currently are not required U
submit permit applications.
In addition, the Part 1 group application deadline for indus
trial facilities owned or operated by municipalities with popu
lations of less than 250,000 has been extended from May 30
1991 to May 18,1992. The Part 2 application deadline has beer
extended from May 18,1992 to May 17,1993.

INTRODUCTION
The U.S. Environmental Protection Agency's
(EPA) Office of Wastewater Enforcement and
Compliance and EPA Region VIII are hosting a
one-day workshop to provide an overview of the
NPDES program requirements for storm water
discharges from municipal separate storm sewer
systems and industrial sources.
Representatives from EPA Headquarters and
EPA Region VIII will discuss numerous issues
including industrial storm water permit applica-
tions, sampling, general permits, pollution
prevention plans, and municipal storm water
management programs.
WHO SHOULD ATTEND
This workshop is open toState and Regional
representatives from EPA Region VIII that are
interested in NPDES storm water permitting
requirements.
