The USEPA has reissued its Multi-Sector General Permit (MSGP) for stormwater discharges associated with industrial activity. The 2015 provisions are similar to those issued in 2008 with changes that are intended to streamline permitting and Stormwater Pollution Prevention Plan (SWPPP) documentation; enhance environmental protections; and improve clarity. The most significant changes include:
This MSGP applies in areas of the country where the USEPA is the National Pollutant Discharge Elimination System (NPDES) permitting authority, including:
To be covered under the 2015 MSGP, industrial facilities previously covered under the 2008 MSGP must submit a NOI by September 2, 2015. Federal operators in the state of Washington have until October 19, 2015 and operators in the state of Idaho (except Indian country) have until November 10, 2015. New or existing eligible industrial facilities located in areas of the country where the USEPA is the NPDES permitting authority that were not covered under the 2008 MSGP will need to submit an NOI a minimum of 30 days prior to commencing discharge, or as soon as possible if discharge has commenced.
The 2015 MSGP does not affect industrial facilities located in states that have USEPA authorization to implement the NPDES stormwater program. Although, as states renew their own industrial storm water general permits, many will use the USEPA’s 2015 MSGP as guidance.
