INDUSTRIAL STORM WATER PERMITTING IN REGION 6:

Region 6 Multi-Sector General Permit (MSGP-2000)
(includes links to guidance on pollution prevention plants, NOIs, NOTs, etc.)

Under Phase I of the Storm Water Program, permits for discharge of storm water from industrial activity have been required since October 1, 1992. Most of the industrial activities are defined using Standard Industrial Activity (SIC) codes, which were the precursor to the newer North American Industrial Classification System (NAICS). For help finding a SIC code, visit:

Industrial activities owned or operated by municipalities with a population under 100,000 (except airports, power plants, and uncontrolled sanitary landfills) were given a later date to start complying (see discussion on ISTEA temporary exemption on EPA's national web site). The date for small municipalities to start getting storm water permits for industrial activities covered by the ISTEA exemption is March 10, 2003.

The EPA Multi-Sector General Permit (MSGP) for storm water associated with industrial activities was issued October 30, 2001. This general permit is available for facilities in New Mexico, Texas, oil & gas facilities in Oklahoma and Texas, and facilities in Indian Country Land in Louisiana, New Mexico (except Navajo and Ute Mountain Ute reservations (see Part 1.1.6 of permit for complete list of Region 6 coverage).

In order to fill out the Notice of Intent for Permit Coverage, you will need to determine whether endangered species are in the vicinity of your facility and certify you meet one of five eligibility options. You must use the procedure in Addendum A of the permit to determine your eligibility. EPA maintains a list of endangered species by county for use with Addendum A.

For the Notice of Intent, you will also need to certify, based on instructions in Addendum B, whether you have met the eligibility conditions of the permit related to protection of historic properties listed or eligible for listing on the National Register of Historic Places. Exit EPA Disclaimer

The MSGP-2000 does not authorize storm water discharges associated with "regulated" construction activities at a facility (see Part 1.2.3.2). Today, this restriction applies to construction projects disturbing 5 or more acres, and small projects that are part of a larger common pan of development or sale that cumulatively disturbs 5 or more acres. Starting March 10, 2003, this restriction will also apply to "small" construction activities in the 1-5 acre range regulated under Phase II of the storm water program. You will need a separate construction storm water permit if you have a regulated construction activity at your facility.
