Approval of the Clean Air Act, Section 112(l), Delegation of Authority to Three Local Air Agencies in Washington

EPA is promulgating direct final approval of the state of Washington Department of Ecology (Ecology) request for program approval and delegation of authority for three local agencies in Washington to implement and enforce locally-adopted hazardous air pollutant (HAP) regulations which adopt by reference the federal National Emission Standards for Hazardous Air Pollutants (NESHAP) contained within 40 CFR Parts 61 and 63, as these regulations apply to all sources (i.e., both Part 70 and non-Part 70 sources). In this action EPA is delegating these programs to Ecology for the purpose of redelegating them to three local agencies in Washington, consistent with Ecology's statute, the Revised Code of Washington (RCW) 70.94.860. EPA is also promulgating approval of a mechanism by which these three agencies will receive delegation of future NESHAPs; and is waiving its notification requirements such that sources will only need to send notifications and reports to the delegated local agencies. Additionally, EPA is promulgating direct final approval of certain local air agency potential-to-emit limiting regulations which will now be recognized as federally enforceable. The adopted regulations approved as part of this action will be implemented and enforced by the following local air authorities within the state of Washington: the Northwest Air Pollution Authority (NWAPA); the Puget Sound Air Pollution Control Agency (PSAPCA); and the Southwest Air Pollution Control Authority (SWAPCA) collectively referred to as ``NWAPA, PSAPCA, and SWAPCA.'' (For purposes of this action and consistent with RCW 70.94.860, ``delegation to NWAPA, PSAPCA, and SWAPCA'' means ``delegation to Ecology for the purpose of redelegation to NWAPA, PSAPCA, and SWAPCA''). Delegation to Ecology to directly implement 40 CFR Parts 61 and 63 and to redelegate the same authority to the remaining four Washington local agencies (the Benton Clean Air Authority, the Olympic Air Pollution Control Authority, the Spokane
