EPA is taking direct final action to approve New Hampshire Department of Environmental Services' (NH DES) request for delegation of authority to implement and enforce its New Source Performance Standards (NSPSs) and National Emission Standards for Hazardous Air Pollutants (NESHAPs) which have been adopted by reference into New Hampshire's state regulations from the Federal requirements set forth in the Code of Federal Regulations. In addition, EPA is taking direct final action to approve NH DES's mechanism for receiving delegation of future NESHAPs and NSPSs. This approval delegates standards for both major and area sources and will automatically delegate future regulations and amendments to regulations once NH DES incorporates these regulations and amendments into its regulations. EPA is taking this action in accordance with the Clean Air Act (CAA).
