Title V of the Clean Air Act requires state and local agencies to adopt an Operating Permit Program for major sources of air pollution. EPA sets forth these requirements under 40 CFR part 70. For areas that do not adopt the program, EPA is the permitting authority and implements the Operating Permit Program under 40 CFR part 71. All state or local agencies in Region 9 have an operating permit program. However, tribes located in Region 9 have not developed such programs. Thus, EPA is the permitting authority on tribal lands. EPA may delegate such authority to a tribe that meets the necessary requirements. Below are the Tribal agencies that have received a part 71 delegation of authority.
Navajo Nation Environmental Protection Agency
Navajo Nation EPA (NNEPA) has received a part 71 Delegation of Authority for the Title V Operating Permit Program. Region 9 also determined that the NNEPA meets the eligibility requirements for treatment in the same manner as a state ("TAS") for the purpose of entering into a delegation agreement and has waived our collection of Part 71 permit fees for those sources covered by the Delegation of Authority. In 2006, the delegation agreement and TAS determination were supplemented to allow NNEPA to also take over title V permitting responsibilities for the Navajo Generating Station and the Four Corners Power Plant. Documents related to NNEPA’s Delegation of Authority are available through the link below.
In addition to Air Permit Program delegations, EPA may delegate the authority to implement certain federal standards to state and local agencies. These standards are an integral part of the permitting program in that they may contain applicable requirements for sources that are permitted under the Clean Air Act. The link below will take you to the page with detailed information regarding delegation of federal standards, including new source performance standards (NSPS), national emissions standards for hazardous air pollutants (NESHAPs), and maximum achievable control technology (MACT) standards.
