What the agency says

The Environmental Protection Agency (EPA) is approving delegation of authority to the Northwest Clean Air Agency (NWCAA) for implementing and enforcing the Federal plan requirements for sewage sludge incineration (SSI) units. 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. This document informs the public of the MOA, provides a copy of the signed document, and amends regulatory text in accordance with the Clean Air Act (CAA).
