TAS - Eligibility Requirements
“CAA” section 301(d) and 40 CFR §49.6 Tribal Authority Rule (TAR)– The applicant is an Indian tribe recognized by the
Secretary of the Interior.– The Indian tribe has a governing body carrying out
substantial governmental duties and functions.– The functions to be exercised by the Indian tribe
pertain to the management and protection of air resources within the exterior boundaries of the reservation or other areas within the tribe’s jurisdiction.
– Indian tribe is reasonably expected to be capable, in the EPA Regional Administrator's judgment, of carrying out the functions to be exercised in a manner consistent with the terms and purposes of the Clean Air Act and all applicable regulations.

Navajo Nation Administers Power Plants
On May 18, 2005 , NNEPA and participants of power plants entered into Voluntary Compliance Agreement (VCA)
Federal statues and executive action granting participants’ rights to operate FCPP and NGS free of Navajo Tribal regulation, interference, or adjudication
VCA resolves the dispute as to Navajo Nation’s jurisdictional authority to regulate power plants – 1960 lease agreement
The Operating Agents ( FCPP, NGS) agreed to with provisions of Navajo Nation’s law incorporated in the VCA and part 71 permit administered by NNEPA pursuant to delegation agreement
If VCA is terminated or expires for a plant, permit then in effect for that plant remains in full force and effect as provided for in 40 CFR § 71.4(k), but plants shall be regulated by U.S. EPA

Federal Implementation Planfor FCPP and NGS
EPA’s promulgation of Tribal Authority Rule clarified that state air quality regulations generally could not be extended to facilities located on the Indian reservation
Plants were previously complying New Mexico (FCPP) and Arizona (NGS) State Implementation Plan (SIP)
• EPA finalized FIP for FCPP (40 CFR 49.5512) on May 7,2007 and a FIP for NGS (40 CFR 49.5513) on March 5, 2010
• FIP is proposed to establish federally enforceable emissions limitations for sulfur dioxide, nitrogen oxides , total particulate matter, and opacity, and requirement for control measures for dust
• Existing pollution control equipment at FCPP includes baghouses and scrubbers for SO2 control and specific burners designed for NOx
control
• Existing pollution control equipment at NGS includes electrostatic precipitators for particulate matter removal and LNB/OFA for NOx
control
• NNEPA incorporated FIP requirements to Title V permit issued to the power plants

Title V Sources Compliance Evaluation
• Review compliance reports submitted by facilities• Maintain database and retention of records• Conduct annual compliance evaluation inspections of
facilities• Write inspection reports and provide compliance assistance• Audit RATA and performance testing • Take actions in case of violations, citizen complaints and
exceedance of permit conditions• EPA maintains its full federal investigative and enforcement
authorities • EPA provides training and guidance to the NNEPA staff to
develop NNEPA’s enforcement program

Navajo Nation Emission Inventory (NNEI) FY 2005
NNEI Objectives
Develop comprehensive inventory of air pollution sources on Navajo Nation
Improve accuracy of baseline emissions estimates
Plan and implement emission reduction strategies, air modeling, regulation development, and policy evaluation
NNEI General Goals
Confirm Title V and identify he non-Title V point sources
Review permit documents and annual EI submitted by the Title V sources along with the FEE Form
Obtain EI data for non-Title V point sources
Identify potential emission sources and activity data to develop area source emission estimates
![Page 15: 1 Navajo Nation Operating Permit Program Anoop Sukumaran, Navajo Nation EPA Tribal Program Development](https://reader038.vdocument.in/reader038/viewer/2022103023/56649e555503460f94b4d41a/html5/thumbnails/15.jpg)

NNEI DeterminationPollutant Source EI Results
NOx Point Source 93% FCPP and NGS
SO2 Point Source 99% FCPP and NGS
VOC and CO Area Source Residential wood combustion, wildfires, and prescribed fires
PM10 and PM2.5 Area Source Paved road dust, unpaved, residential wood combustion
NH3 Area Source Livestock, wildfires, prescribed fires
![Page 16: 1 Navajo Nation Operating Permit Program Anoop Sukumaran, Navajo Nation EPA Tribal Program Development](https://reader038.vdocument.in/reader038/viewer/2022103023/56649e555503460f94b4d41a/html5/thumbnails/16.jpg)
16
Scope for Future Work• Inventoried point source improvements: Stack
parameters • Known Missing Point Source Facilities: Minor source
issue , lack of data to calculate emission estimates• Other Missing Point Source Facilities: Possible point
source emissions are included in the area source inventory , a detailed survey needed to develop estimates
• Data Needed to develop emissions estimates for additional Non-Title V point sources: Assumptions were made for emissions estimates
• Missing Area Source Categories: Nonexistent on NN, insignificant, data unavailable

Regional Haze Rule (RHR)40 CFR Subpart P §51.300-51.309
The Clean Air Act requires (Best Available Retrofit Technology) BART review when any source that “emits any air pollutant which may reasonably be anticipated to cause or contribute to any impairment of visibility” in any 156 Federal Class I area
Sixteen (16) and eleven (11) Class I area within 300 km (186 mi) radius of Four Corners Power Plant and Navajo Generating Station
Predicted visibility impact with baseline emissions exceeds 0.5 delta-deciview
