Ted Stevens Anchorage International Airport (ANC-GP)

DEC has developed a stormwater general permit specifically for the Ted Stevens Anchorage International Airport. This permit replaces the Multi-Sector General Permit (MSGP) for industrial facilities working on the airport property. The ANC-GP went into effect
November 1, 2019
and expired on October 31, 2024. This permit has been administratively extended until a new version is issued, expected in summer 2025. Once the new version is issued permittees will have 120 days to file for coverage under the new permit. 

Operators of industrial facilities at Ted Stevens Anchorage International Airport requiring an APDES Stormwater Permit are required to obtain coverage under the ANC-GP if their activities are included within one of four Standard Industrial Classification (SIC) Codes:

  • 4512 – Air Transportation, Scheduled
  • 4513 - Air Courier Services
  • 4522 - Air Transportation, Nonscheduled
  • 4581 - Airports, Flying Fields, and Airport Terminal Services
