Approval of the Clean Air Act (CAA), Section 112(l) Program and Delegation of Authority to the State of Oklahoma

The EPA is approving by direct final rulemaking the Oklahoma Department of Environmental Quality's (ODEQ) request for program approval of adequate authorities and resources to implement and enforce Federal National Emission Standards for Hazardous Air Pollutants (NESHAP) in 40 CFR parts 61 and 63, as these regulations apply to non- part 70 sources. The EPA is approving ODEQ's mechanism for receiving delegation of unchanged NESHAPs as they apply to non-part 70 sources. Also, EPA is delegating authority to ODEQ to implement and enforce certain Federal NESHAPs hazardous air pollutant regulations which ODEQ has adopted by reference into their State rules as they apply to all sources (i.e., both part 70 and non-part 70 sources). These are NESHAPs found in 40 CFR parts 61 and 63. The EPA is also delegating specified General Provisions to parts 61 and 63 as these regulations apply to all sources. The EPA is waiving its notification requirements so sources will only need to send notifications and reports to ODEQ. This action is taken under the authority of CAA section 112(l) and 40 CFR part 63, subpart E. This action does not apply to areas in Indian Country over which the State of Oklahoma has not demonstrated authority.
