EPA solicits public comment on permit to reduce stormwater discharges from construction sites

The U.S. Environmental Protection Agency (EPA) is releasing for public comment a draft permit to regulate the discharge of stormwater from construction sites.

The proposed Construction General Permit (CGP) includes a number of enhanced protections, including enhanced provisions to protect impaired and sensitive waters. Some of the significant proposed permit modifications include new requirements for: Eligibility for emergency-related construction; required use of the electronic notice of intent process; sediment and erosion controls; natural buffers or alternative controls; soil stabilization; pollution prevention; site inspections; stormwater pollution prevention plans; and permit termination.

Many of the new permit requirements implement new effluent limitations guidelines and new source performance standards for the construction and development industry that became effective on Feb. 1, 2010. These requirements include a suite of erosion and sediment controls and pollution prevention measures that apply to all permitted construction sites.

The permit will be effective in areas where EPA is the permitting authority, including four states (Idaho, Massachusetts, New Hampshire and New Mexico); Washington, D.C.; most territories; and most Indian country lands.

The public will have 60 days to comment on the draft permit. EPA anticipates that it will issue the final construction general permit by Jan. 31, 2012.

The current permit is scheduled to expire on June 30, 2011; however, EPA is proposing to extend the current permit until Jan. 31, 2012 to provide sufficient time to finalize the new permit.
