Because every industrial site is unique,
every SWPPP is unique. The SWPPP
needs to be reviewed and updated by the
operator on a regular basis. Please visit
www.epa.gov/npdes/stormwater/msgp
for more information on how to develop
your SWPPP.

3. Complete documentation for
  eligibility under other Federal laws.
The operator must assess the potential
effects of stormwater runoff on federally
listed endangered and threatened species
and any designated critical habitat located
on or near the site, as well as impacts
on historic properties on or near the
facility. In making these determinations,
the operator needs to consider areas
beyond the immediate footprint of the
facility site as well as beyond the property
line—areas that could be affected directly
or indirectly by stormwater discharges.
The MSGP contains more information
about completing these determinations in
applying for permit coverage.

4. File a Notice of Intent (NOI)
  application.
The Notice of Intent (NOI) form lets
EPA know that you are filing for permit
coverage.  It also attests that you have
read, understood, and are complying with
the requirements of the MSGP. The fastest
and easiest way to file an NOI is through
EPA's online  permit application system
(www.epa.gov/npdes/enoi). (Mailing a
paper NOI to EPA can add 2 or more
weeks to your processing time.) Your
permit coverage begins after a 30-day
waiting period, during which NOIs are
reviewed by EPA and others.

5. Implement all stormwater control
  measures outlined in your SWPPP.
Your SWPPP must be updated as
conditions at  the industrial facility and as
practices change.

Many Industrial Facilities (with few exceptions) Need Storm water Permit Coverage!
Why is stormwater runoff a
problem?
Runoff from rainstorms and snowmelt picks
up pollutants like sediment, oil and grease,
nitrogen, phosphorus, and other chemicals
and carries them into storm drains or
directly into waterbodies. Because most
storm drain systems do not provide
any treatment to the water they collect,
preventing contamination of stormwater
is critically important. Otherwise, polluted
runoff will be discharged untreated into  the
waterbodies we use for swimming, fishing,
and drinking water.

This brochure describes who must
comply with the EPA's stormwater permit
requirements for:
•  Idaho
•  Federal facilities in Washington
•  Indian Country within Alaska, Idaho,
   Oregon and Washington.*
   If your facility is not in one of the areas
   noted, you will need to obtain permit
   coverage from the appropriate state
   authority. A list of state permitting authorities
   can be found afwww.epa.gov/npdes/

What is the Multi-Sector General
Permit, or MSGP?
EPA's National Pollutant Discharge
Elimination System (NPDES) program
regulates stormwater runoff from industrial
facilities. The Multi-Sector General Permit
(MSGP) covers industrial facilities in 29
different industrial sectors.

If your facility...
•  is located in Idaho, Indian Country or is
   a Federal facility in Washington,
•  has "primary" or "co-located" industrial
   activities covered by the MSGP,
•  has stormwater runoff that discharges to
   a surface water or to a storm sewer that
   flows to a surface water,
you need permit coverage under the Multi-
Sector General Permit.

What industries are covered by the
MSGP?
Permit eligibility is limited to discharges
from facilities in the "sectors" of industrial
activity listed. The sector descriptions are
based  on Standard Industrial Classification
(SIC) Codes and Industrial Activity Codes.
For a more detailed list, please see
Appendix D of the MSGP. The industrial
sectors listed in the table must minimize
pollutants in their stormwater discharges
and obtain permit coverage under the
MSGP.

                                                                                                      requirements.
  Who is responsible for coverage
     and who submits an NOI?

The "operator" submits a Notice of Intent
(NOI) application. The operator is the entity
(generally the company, corporation, etc.)
that has operational control over the industrial
activities, or has day-to-day operational
control of activities at the facility necessary
to implement the Stormwater Pollution
Prevention Plan (SWPPP—see below/
next page for more information) and ensure
compliance with the permit (e.g., the entity
is authorized to direct workers at a facility to
carry out activities required by the permit).

It is the responsibility of the operator(s)
to develop and implement a SWPPP and
maintain all "best management practices" or
stormwater control measures at the facility.
These include swales, detention ponds, spill
protection equipment, schedules of activities,
prohibitions of practices, and maintenance
procedures that you use to prevent or reduce
the discharge of pollutants.
                                                                                                     2. Develop a site-specific stormwater

                                                                                                     pollutants in stormwater runoff from
                                                                                                     your facility. It is a written document that
                                                                                                     identifies the sources of pollution and
                                                                                                     industrial activities conducted at the site,
                                                                                                     including stormwater control practices

                                                                                                     pollutants from making their way into
                                                                                                     stormwater runoff. The SWPPP must be
                                                                                                     completed before you apply for permit
                                                                                                     coverage. EPA does not require that you
                                                                                                     submit the SWPPP with your application
