Tribal Minor New Source Review (NSR)
Registration for Existing True Minor Sources of Air Pollution in Indian Country

This webpage provides the information and tools that may help you determine if you are required to register your “true” minor source of air pollution with the U.S. Environmental Protection Agency (EPA).

On June 10, 2011, the EPA finalized the Tribal New Source Review (NSR) Rule (PDF) (62pp, 499k), which helps to protect air quality in Indian country. Under the Tribal NSR Rule, existing “true” minor sources that emit air pollution at certain levels must register their facility with the EPA by March 1, 2013. True minor air pollution sources are generally small businesses or operations such as neighborhood dry cleaners or gas stations.

In order to help true minor sources register, we developed calculators for common source types to help you determine if you must register under this rule. Please note that if you have a source that emits at the threshold levels and we don’t have a calculator for you, you must still register. Please see the registration form shown below.

Do You Own/Operate a: Does Your Facility Use:
  • Gas station
  • Dry cleaner
  • Auto body repair/refinishing shop
  • Sawmill operation
  • Landfill operation
  • Hot mix asphalt plant
  • Concrete batch plant
  • Printing operation
  • Sand, gravel, or rock crushing facility
  • Surface coating operation
  • Degreaser/solvent/cleaner
  • Industrial boiler
  • Compression or spark ignition engine, such as an emergency generator

To determine if you must register your facility, please complete the appropriate Registration Calculator(s) below. Each Registration Calculator contains specific and detailed information and directions to help you provide the facility information needed to determine registration applicability.

Please carefully review all the directions contained in the Registration Calculator(s) and complete the appropriate Calculator(s) as accurately as possible. Note: you may need to complete more than one Registration Calculator for your facility; if for example, you operate a gas station that uses an emergency generator.

Once you provide all the requested information, the Registration Calculator’s Output-Summary Printout page will guide you through the final steps of the registration process, if required.

to determine if you must register under the Tribal NSR Rule

Gas stations (xlsx file) (78k), which are private or public facilities where gasoline is dispensed into vehicle fuel tanks.

Dry cleaning operations (xlsx file) (88k), which commonly use petroleum solvents as cleaning fluids in commercial and industrial dry cleaning operations.

Auto body shops (xlsx file) (95k), which repair, repaint, and customize cars, trucks, and other vehicles. Activities include sanding, cleaning, priming, and painting.

Sawmills (xlsx file) (107k), which take harvested logs and process them into lumber suitable for construction or the creation of other wood products.

Landfill operations  (90k), which receive household waste and are not classified as a land application unit, surface impoundment, injection well, or waste pile. In addition to household waste, the landfill operations may receive other types of waste such as commercial solid waste, nonhazardous sludge, and industrial solid waste.

Hot-mix asphalt plants (97k) , which mix and heat a combination of aggregate, recycled materials, and liquid cement to produce asphalt suitable for paving applications.

Concrete batch plants  (77k), which are designed to dispense water, cement, sand, coarse aggregate, and other supplements in a proportion that can be mixed to create concrete. The mixing processes at these plants can be either truck mixes or central mixes.

Printing operations  (89k), which include the application of ink onto packaging, greeting cards, books, catalogues, directories, newspapers, etc. using web offset lithography, web letterpress, rotogravure, or flexography processes.

Rock crushing and stone processing operations, including sand and gravel production  (127k), which extract useful rocks and minerals and crush them to a desired size and consistency.

Surface coating operations  (102k), which involve applying a thin layer of coating (e.g., paint, lacquer, enamel, varnish, etc.) to a substrate (e.g., paper, metal, plastic) for decorative or protective purposes.

Degreasers/solvents/cleaners   (91k), which are used to remove water-insoluble contaminants such as grease, oils, waxes, carbon deposits, fluxes, and tars from metal, plastic, glass, and other surfaces. Degreasers/solvents/cleaners are typically used prior to painting, plating, inspection, repair, assembly, heat treating, and machining.

Industrial boilers (xlsx file) (137k), which are typically used to generate hot water or steam needed to power other processes, such as electricity generation. Some industries use boilers in a method known as cogeneration, where steam from the boilers will power one process, such as a turbine, after which excess steam and heat will be used for another process or energy recycling. Boilers create steam from the combustion of fuel, usually coal, oil, or natural gas; though a wide variety of fuels can be used.

Stationary internal combustion engines (xlsx file) (135k), which include two ignition methods - spark ignition and compression ignition. Spark ignition engines burn gasoline or natural gas, which have a relatively high ignition temperature and require an electrical discharge to initiate combustion. Compression ignition engines burn diesel fuel, which has a relatively low ignition temperature and can spontaneously ignite since the compressed air temperature is above the auto-ignition temperature of the fuel.

May I register using my own emission information, rather than using the Registration Calculators?

The Registration Calculators are provided for the convenience of most minor sources, which are unlikely to have tracked emissions data since minor sources in Indian country have been unregulated until now. However, if you have actual emission data from your source you may choose not to use the calculator(s), but your registration information must comply with all of the requirements in 40 CFR 49.160 and be submitted using the form for registration of existing sources located at:

http://www.epa.gov/air/tribal/pdfs/existing_source_registration_rev.pdf (7pp, 47k)

or

Existing Source Registration.doc (7pp, 110k)

 

How does registration relate to obtaining a permit?

Please note that registering your air pollution source does not relieve you of the requirement to obtain any required permit if you find you are above the major source threshold. Registering your source and obtaining a permit, if needed, are two different and separate requirements and require different facility emission information.

If you have any questions about the Tribal NSR Rule, true minor source registration requirements, or how to complete the Registration Calculator(s) please contact the person listed below at your EPA Regional office.
