No Exposure Certification for the New Industrial Storm Water Permit

No Exposure Certification (NEC) allows exemptions from certain requirements of the new National Pollutant Discharge Elimination System Industrial General Permit (IGP) 2014-0057-DWQ (effective July 1, 2015) for dischargers whose industrial activities and materials are not exposed to storm water. Dischargers who file valid NECs are not required to implement best management practices or comply with the Storm Water Pollution Prevention Plan and general monitoring requirements of the IGP. “Light industry” facility dischargers who were excluded from coverage under the previous IGP and who meet the no exposure conditions must submit the NEC on or before October 1, 2015. Dischargers who have existing coverage under the IGP may register for NEC coverage at any time following completion of facility changes that meet the no exposure requirements.

Stratus Environmental’s staff can assist your facility in obtaining IGP coverage and potentially certifying for no exposure. See our Services page for more information about Stratus Environmental’s storm water services.
