Operating Permit Program


The Operating Permit Program entered into a delegation agreement with U.S. EPA to administer Part 71 Title V Permits for major facilities on the Navajo Nation.  The Navajo Nation was the first tribe ever to receive this authority.  The Operating Permit Program has now issued Title V Permits to the following facilities; El Paso Natural Gas, Transwestern Natural Gas, Conoco Phillips Wingate Fractionating Plant, Peabody Western Coal, Navajo Generating Station and Four Corners Power Plant.  All together there are currently 13 Title V facilities operating on the Navajo Nation.


Our Program Responsibilities are as follows:

  1. Issuance of Title V permits to large industrial facilities on the Navajo Nation 
  2. Compliance and Enforcement Inspections at Title V permitted facilities
  3. Address Title V Citizen Complaints
  4. Establish and Maintain an Emission Inventory
  5. Study new proposed federal regulations to enhance and amend the Navajo Air Pollution Control and Prevention Act
  6. Outreach and Education Activities

The Permitting Process:

A Title V permit grants a facility the permission to operate by abiding by all Clean Air Act Requirements.  This includes emission limits, monitoring requirements, recording keeping requirements and reporting requirements.  The permitting process is as follows:

  1. A facility will submit a Permit Application
  2. A title V permit is Drafted
  3. 30 day Public Notice
  4. Response to comment
  5. Final Permit issuance

What is the Role of the Public in Permits?

When a Title V facility is going through the permitting process the public has the right to submit comments that relate to the permit conditions.  It is important for concerned citizen to become aware of what facilities are operating within their radius and become knowledgeable of their operations.  Citizens can ask questions, provide comments, submit concerns and request for Navajo Air Quality Regulations, copies of permits, general information and request for a public workshop.
