EPA is seeking public comment on extending the 2008 stormwater construction general permit by 1 year to June 30, 2011. The permit applies 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 permit regulates the discharge of stormwater from construction sites that disturb 1 acre or more of land, and from smaller sites that are part of a larger, common plan of development. The permit requires construction site operators to comply with stormwater discharge requirements that are intended to prevent sediment loss, soil erosion, and other pollution issues at active construction sites.

The extension of the 2008 permit is needed to allow the agency sufficient time to coordinate a revised permit with a second effort that is under way to establish national clean water standards, known as an effluent limitation guideline, for the construction and development industry by December 1, 2009. The public will have 30 days to comment on the proposed extension to the permit after publication in the Federal Register.
