Revised EPA 2012 Construction General Permit (CGP) Released

U.S. Environmental Protection Agency (EPA) is issuing a new general permit for stormwater discharges from construction activities. The 2012 construction general permit (CGP) is required under the Clean Water Act and replaces the existing 2008 CGP, which expired on February 15, 2012. The new permit includes a number of enhanced protections for surface waters, including provisions to protect impaired and sensitive waters. The 2012 CGP updates include requirements intended to limit erosion, minimize pollution sources, provide natural buffers or their equivalent around surface waters, and further restrict discharges to areas impaired by previous pollution discharge.

Many of the permit requirements implement new effluent limitations guidelines and new source performance standards for the construction and development industry that became effective on February 1, 2010, which include pollution control techniques to decrease erosion and sediment pollution.

The permit will be effective in areas where EPA is the permitting authority: Idaho, Massachusetts, New Hampshire, New Mexico, Washington, D.C., and most U.S. territories and in Indian country lands.
