EPA Reissues NPDES Storm Water Multi-Sector General
Permit for Industrial Activities
The EPA recently published a notice of the "Final Reissuance of National
Pollutant Discharge Elimination System (NPDES) Storm Water Multi-Sector
General Permit for Industrial Activities) at 65 FR 64746 October 30th,
2000). It is available online at www.epa.gov/fedrgstr/EPA-WATER/2009/February/Day-26/w4152.htm.
The Multi-Sector General Permit (MSGP) was effective October 1, 2000
and applies in states where the NPDES permit program has not been delegated:
Maine, Massachusetts, New Hampshire, New Mexico, Arizona, and Idaho. The
newly issued MSGP replaces the 1995 MSGP and applies to any facilities
currently covered by the 1995 MSGP as well as any new facilities seeking
coverage under the 2000 MSGP.
Changes from the 1995 MSGP are summarized in Section II of the notice.
The most significant changes regard requirements pertaining to compliance
with the National Historic Preservation Act (NHPA) and the Endangered

the opportunity for facilities to obtain exemption from the permit program
by certifying "no exposure."
Facilities already covered under the existing (1995) MSGP must certify
compliance with the revised ESA and NHPA requirements by January 29,
2000. To be covered under the reissued MSGP, facilities must be able to
certify that their storm water discharges and Best Management Practices
(BMPs)implemented to control storm water runoff do not affect a historic
property or listed endangered or threatened species. A new list of species
and their locations is provided in Addendum A to the permit notice.
The "No exposure" exemption is available to facilities that can certify
to no exposure of storm water to facility pollutants by answering a 12
question checklist appended to the notice.
Facilities must also update their Storm water Pollution Prevention plans
(SWPPs) to comply with any new requirements by January 29, 2001 or request
