WASHINGTON, D.C. — Under the Clean Water Act Action Plan (October 15, 2009), OECA and OWM committed to creating a website that features a national web-based inventory for all non-stormwater NPDES general permits issued by states and the Environmental Protection Agency (EPA). The web inventory went live in September 2012 and has now been updated to include stormwater general permits. The non-stormwater portion has also been updated with data current as of March 2013.

The web inventory can be accessed at http://cfpub.epa.gov/npdes/permitissuance/genpermits.cfm.

The web inventory includes 767 non-stormwater and stormwater general permits and is designed with a search tool to provide easily accessible information on master general permits, such as: permit category, permit number, state, permit title, EPA Region, issuance and expiration dates, estimated number of facilities covered by each master general permit, and permitting authority. Where a general permit is available on a state website, the web inventory provides a link so that the specific terms of the general permit can be easily viewed.
