EPA Re-Issues Permit for Construction Site Stormwater

EPA is reissuing a stormwater Construction General Permit (CGP), which expired July 1, 2008, for a two-year time period. The permit will apply only where EPA is the permitting authority, which is in five states (Massachusetts, New Hampshire, New Mexico, Idaho, and Alaska); Washington, D.C.; most territories; and most Indian country lands.

The CGP regulates the discharge of stormwater from construction sites that disturb one acre or more of land, and from smaller sites that are part of a larger, common plan of development. The permit requires operators of the construction sites to use stormwater controls and develop stormwater-pollution prevention plans to minimize the discharge of sediment and other pollutants associated with construction sites in stormwater runoff.

Under the reissued permit, new dischargers include new construction sites that start construction on or after the effective date of this permit and those that have already started construction, but do not have coverage under the 2003 CGP. Sites that have coverage under the 2003 CGP must continue to comply with the provisions of that permit and do not need to apply for coverage under this new permit.

The new permit uses most of the same terms and conditions as EPA's 2003 permit. EPA is coordinating the permit with a second effort already underway to establish national clean water standards, known as an "effluent limitation guideline," for the construction and development industry. Upon finalization of the guideline, EPA plans to include its provisions in a new-and-improved five-year CGP to be reissued no later than July 2010.
