Final Approval of the Clean Air Act, Section 112(l), Delegation of Authority to Washington Department of Ecology and Four Local Air Agencies in Washington

Pursuant to the authority of Clean Air Act (CAA), section 112(l), The United States Environmental Protection Agency, Region 10 (EPA) approves the State of Washington Department of Ecology's (Ecology) request, and the requests of four local air pollution control agencies in Washington, for program approval and delegation of authority to implement and enforce specific federal National Emission Standards for Hazardous Air Pollutants (NESHAP) regulations (as they apply to both part 70 and non-part 70 sources) which have been adopted into state law. EPA delegates these programs to Ecology for the purpose of direct implementation and enforcement (within Ecology's jurisdiction). EPA also delegates these programs to the following four local agencies: the Benton Clean Air Authority (BCAA), the Olympic Air Pollution Control Authority (OAPCA), the Spokane County Air Pollution Control Authority (SCAPCA), and the Yakima Regional Clean Air Authority (YRCAA). EPA also approves a mechanism by which Ecology and the four local agencies will receive delegation of future NESHAPs; and waives its notification requirements such that sources within Ecology, BCAA, and SCAPCA's jurisdictions only need to send notifications and reports to Ecology, BCAA, or SCAPCA, and do not need to send a copy to EPA. Delegation to the remaining local agencies in the State of Washington (the Northwest Air Pollution Authority, the Puget Sound Clean Air Agency, and the Southwest Air Pollution Control Authority) was promulgated in a direct final rule on December 1, 1998. A correction and clarification to that direct final rule was published on February 17, 1999, and amendments updating this delegation were published on April 22, 1999, and February 28, 2000.
