New 2013 Storm Water Multi-Sector General Permit Almost Final

EPA’s new 2013 Multi-Sector General Permit for storm water discharges from industrial facilities is expected to be released in the next few months.  New requirements include:

  • Revisions to the technology-based effluent limits (i.e. control measures);
  • More specific deadlines for taking corrective actions;
  • Updated Storm Water Pollution Prevention Plan (SWPPP) documentation requirements;
  • Increased public access to SWPPP information;
  • Electronic submission requirements for the NOI, NOT, annual reports, and monitoring;
  • Addition of saltwater benchmark values for metals;
  • Additional requirements for facilities discharging to federal Superfund sites;
  • Once the final 2013 MSGP permit is issued, a new Notice of Intent (NOI) must be submitted to the EPA within 90 days to continue coverage.

storm-water1If your facility was covered by the 2008 MSGP, it’s business as usual. The EPA has granted an automatic administrative continuance of permit coverage which will be valid until the new permit is issued. Once the final 2013 MSGP permit is issued, a new Notice of Intent (NOI) must be submitted to the EPA within 90 days to continue coverage.  If your facility began discharging storm water after September 27, 2013 and did not have coverage under the 2008 MSGP, you are currently protected by EPA’s “No Action Assurance” memo.  But be careful, because the “No Action Assurance” memo will expire on March 30, 2014, or 30 days after the issuance of the final 2013 MSGP, whichever comes first.Read more at EPA.
