National Emission Standards for Hazardous Air Pollutants; Delegation of Authority to Arkansas

Résumé

The EPA is proposing to approve, through a "direct final" procedure, a request for delegation of the Federal air toxics program contained within 40 CFR Parts 63 pursuant to Section 112(l) of the Clean Air Act (Act). The State's mechanism of delegation involves the straight delegation of certain existing and future Section 112 standards unchanged from the Federal standards. The actual delegation of authority of individual standards, except standards addressed specifically in this action, will occur through a mechanism set forth in a memorandum of agreement (MOA) between the Arkansas Department of Environmental Quality (ADEQ) and EPA. ADEQ is requesting delegation and approval to implement and enforce the existing Part 63 standards as they apply to Part 70 sources, including major and area sources subject to the Title V (Part 70) permitting requirements. The delegation of authority under this action does not include CAA Section 112(r).
