Intended Final NPDES General Permit AKG282100
And Related Regulatory Documents (EPA, Oct 2012)
For Oil and Gas Exploration in the Beaufort Sea, Alaska


In October 2012, the U.S. Environmental Protection Agency released its intended Final NPDES General Permit AKG282100 (a.k.a AKG-28-2100) for the Beaufort Sea, Alaska. The EPA
administratively extended the previous General Permit (AKG280000) that nominally expired in June 2011.

The previous permit (2006) covered the Arctic Ocean relative to oil and gas exploration in coastal and offshore Alaska, which includes both the Beaufort and Chukchi Seas. The public comment period ended for this
intended Final permit on March 30, 2012 but the EPA has only recently (Oct 2012) listed the public comments on its webpage for the final permit. The 2012 permit is also variously labeled as AKG-28-2100. The EPA signed separate
permits for the Beaufort and Chukchi Seas on October 23, 2012 with an effective date of November 28, 2012. The expiration date of the intended final permit is November 27, 2017.
