The new National Pollutant Discharge Elimination System (NPDES) General Permit (IGP) will be effective June 1, 2017. With the issuance of the new permit, eReporting is required for submittal of both the Notice of Intent (NOI) and compliance forms. Facilities that were permitted under the 2012 IGP must submit an NOI by June 30, 2017 and update their Stormwater Pollution Prevention Plan (SWPPP) by August 29, 2017 to continue stormwater permit coverage. Facilities seeking first-time coverage under the 2017 IGP must first prepare a SWPPP and then submit an NOI to obtain permit coverage. Important changes to the 2017 IGP include the requirement to use the GEOS e-reporting system, the inclusion of separate benchmark concentrations for metals discharged into saline waters, and the inclusion of new effluent limitations.
