Tribal NSR Actions in Region 9
EPA has authority to issue Non-attainment New Source Review Permits (major non-attainment NSR) and minor New Source Review permits (minor NSR) on Tribal Lands under 40 CFR 49. Note that EPA issues Prevention of Significant Deterioration permits under 40 CFR 52.21 on Tribal Lands as well. For a listing of PSD permits, view Prevention of Significant Deterioration (PSD) Permits Issued by Region 9.

EPA promulgated the Review of New Sources and Modifications in Indian Country (62 pp, 499 K, About PDF) on July 1, 2011. The final rule is a federal implementation plan (FIP) that outlines preconstruction permitting of air pollution control requirements for industrial facilities located in Indian Country.
The FIP includes two New Source Review (NSR) rules for the protection of air quality in Indian country. One of those rules, known as the Tribal Minor NSR Rule, applies to new industrial facilities or modifications at existing industrial facilities with projected emissions that are more than the minor NSR thresholds but less than the major NSR thresholds, which are generally 100 to 250 tons per year (tpy).
The FIP allows EPA Region 9 to review applications for and issue minor NSR permits to industrial facilities within the federally-recognized external boundaries of Reservations in the Region (Arizona, California, Hawaii, and Nevada). The FIP also allows EPA to delegate that authority to tribes in the Region that request it and are able to demonstrate appropriate capability to implement the FIP. Additionally, the FIP can be replaced by an EPA-approved tribal implementation plan (TIP).
- Site-Specific Permits: includes case-by-case determinations of the source emission limits as well as any control technology requirements
- General Permits: permits that have been developed for a number of similar equipment types or facilities to simplify the permit issuance process for facilities; or
- Synthetic Minor Permits: applies to a facility that has the potential to emit pollutants in amounts that are at or above major source thresholds, but has voluntarily accepted emission limits so that its potential emissions are below those thresholds, allowing the facility to avoid more stringent major NSR requirements of the Clean Air Act, such as Prevention of Significant Deterioration (PSD), and Title V Operating Permit requirements. This option is available to different types of facilities, including those that emit hazardous air pollutants so that they will not be subject to National Emissions Standards for Hazardous Air Pollutants, also known as Maximum Available Control Technology (MACT) standards, for major sources.
The permit issuance process includes public notice and comment requirements, as well as administrative and judicial review provisions.
Your potential regulated air pollutant emissions must be greater than the thresholds in the table below and less than the major NSR thresholds.
|Regulated NSR pollutant||Minor NSR Thresholds for
Non-Attainment Areas (tpy)
|Minor NSR Thresholds for
Attainment Areas (tpy)
|Carbon monoxide (CO)||5||10|
|Nitrogen oxides (NOx)||5 b||10|
|Sulfur dioxide (SO2)||5||10|
|Volatile Organic Compounds (VOC)||2 b||5|
|Sulfuric acid mist||NA||2|
|Hydrogen sulfide (H2S)||NA||2|
|Total reduced sulfur (including H2S)||NA||2|
|Reduced sulfur compounds (including H2S)||NA||2|
|Municipal waste combustor emissions||NA||2|
|Municipal solid waste landfill emissions
(measured as nonmethane organic compounds)
b In extreme ozone nonattainment areas, section 182(e)(2) of the Act specifies that any change at a major facility that results in any increase in emissions is subject to permitting. In other words, any changes to existing major facilities in extreme ozone nonattainment areas must comply with a "0" tpy threshold, but that threshold does not apply to minor facilities.
We recommend contacting the EPA Region 9 Air Permits Section for a preliminary application meeting to ensure the correct application form and supplemental information is submitted. For example, your application could be delayed if it does not sufficiently address impacts to endangered species, cultural resources and/or air quality. Please contact R9AirPermits@epa.gov for more information.
