ACI-NA Submits Comments on EPA's Draft Multi-Sector General Permit for Stormwater Discharges

Last month, ACI-NA submitted comments developed by the Water Quality Working Group in response to the Environmental Protection Agency's (EPA) proposed revision to the Multi-Sector General Permit (MSGP), or the Draft National Pollutant Discharge Elimination System (NPDES) General Permit for Stormwater Discharges from Industrial Activities (click here for draft MSGP and associated documents).  In addition, the Federal Stormwater Association which represents a number of industrial, municipal, and construction-related entities (of which ACI-NA is a member) also submitted comments.  

Industrial stormwater has been regulated by the EPA since the promulgation of the agency's 1990 stormwater regulations, which established NPDES permit requirements for “stormwater discharges associated with industrial activity.” EPA’s first MSGP for stormwater discharges associated with industrial activity was issued on September 29, 1995, and has since been reissued in 2000 and 2008.  Although the EPA’s MSGP applies only in areas of the country where EPA remains the NPDES permitting authority, many states that act as their own permitting authority use the EPA's MSGP as a guide to develop their own.   The Draft MSGP addresses stormwater discharges from industrial activities and specifically from air transportation facilities in Sector S.  

The Water Quality Working Group developed ACI-NA's comments in response to the draft permit, focusing both on the general provisions and on the proposed requirements for the aviation industry. The FWSA focused its comments on the general provisions of the draft permit.   In our comment letter, ACI-NA points out several sections of the draft permit that are unclear, confusing, and/or impractical.  The Water Quality Working Group will continue to monitor activity on the draft MSGP over the coming months.
