The Federal plan addresses the implementation and enforcement of emission limits and other control requirements for designated air pollutants. On December 11, 2018, the EPA Region 10 Regional Administrator and the Executive Director of NWCAA signed a Memorandum of Agreement (MOA) concerning delegation of authority of the Federal plan to NWCAA, which became effective upon signature. The geographic area covered by this MOA comprises Island, Skagit, and Whatcom Counties in the State of Washington, except in Indian country.
