Multi-Sector General Permit OKR05 Issued

5 Aug 2011 - The Oklahoma Department of Environmental Quality (ODEQ), Water Quality Division received ten (10) written comments from two (2) parties concerning the draft general permit OKR05 for storm water discharges from industrial facilities under the Multi-Sector General Permit (MSGP) within the state of Oklahoma.

After reviewing the comments and considering issues with the permit, changes were made to the draft permit. ODEQ's responses to comments were provided to all parties that submitted comments following the thirty (30) day public comment period.

The final permit effective date is September 5, 2011. This permit replaces the previous permit, which expired on May 2, 2011.

Facilities seeking new coverage under this general permit must receive an authorization to discharge from ODEQ. In order to receive this authorization from ODEQ, facilities must file a Notice of Intent (NOI) and pay the application fee of $100 to ODEQ.

Existing permit holders must file a new NOI no later than December 5, 2011. Storm water pollution prevention plans (SWP3) must also be revised and implemented no later than December 5, 2011.

Owner/operators of new or relocated facilities must submit a new NOI a minimum of thirty (30) days prior to commencing operation of the facility. A Storm Water Pollution Prevention Plan (SWP3) must be developed and implemented prior to submitting an NOI.

Facilities located within any corridor/area of Federal and State sensitive waters and watersheds for listed species (Exhibit 1 in the MSGP), as defined by the U.S. Fish & Wildlife Service (USFWS) and Oklahoma Department of Wildlife Conservation (ODWC), must submit a complete SWP3 to ODEQ with the NOI submittal. Documentation supporting the determination of permit eligibility with regard to specific endangered species must be included with the SWP3. ODEQ will review each SWP3 to determine if it meets the minimum permit requirements and require amendments as necessary. USFWS and ODWC have the option of requesting additional information from any owner/operator and reserve the right to review SWP3s and best management practices.

Facilities not located within corridors/areas of Federal and State sensitive waters and watersheds or scenic river watersheds are not required to submit an SWP3 for review unless specifically requested by ODEQ.
