EPA Extends 2008 Construction Stormwater Permit

US EPA has proposed to extend the 2-year term of the Agency’s July 2008 general permit for stormwater discharges from construction activities (CGP) by 1 year. According to EPA, the extension is needed to ensure Agency compliance with a court order requiring promulgation of effluent limitations guidelines (ELG) and new source performance standards (NSPS) for the construction and development (C&D) point source category.

The 2008 CGP provides coverage for discharges from construction sites in areas not addressed by an approved state national pollutant discharge elimination system (NPDES) program. EPA Regions 1, 2, 3, 5, 6, 7, 8, 9, and 10 issued the 2008 CGP to replace the expired 2003 CGP for operators of new and unpermitted ongoing construction projects. The current 2008 CGP expires on June 30, 2010.

EPA is proposing to extend coverage of the CGP to June 30, 2011. This would give EPA approximately the same time period—18 months—that the Agency required to issue the 2003 CGP. The 2008 CGP required 3 years to finalize.
