Air Pollution Control Self Inspection Checklist |
Guidelines: Federal air pollution control regulations are contained in Title 40 of the Code of Federal Regulations (40 CFR). These regulations are promulgated by the Environmental Protection Agency (EPA) and are based on the requirements of various parts of the Federal Clean Air Act. The goal of these regulations is to ensure that substances are not emitted into the air at concentrations that could cause air pollution. The major provisions of the air pollution regulations include procedures for obtaining air emission permits, regulation of maximum allowable emissions of certain gases and particulate matter, procedures for proper use of equipment that could cause the emission of pollutants into the air, and requirements for certain operations and chemicals known to be particularly capable of causing air pollution. Many EPA regulations apply only to major sources of substances and have requirements that are based on a source's potential to emit those substances. State air pollution control programs may incorporate many of these rules; however, other State-specific requirements, including the regulation and permitting of smaller sources, also apply. The user of this checklist should also be familiar with all applicable State and local rules and regulations.
Air Permits
Operating permits are required under the provisions of Title V of the Clean Air Act of the Clean Air Act Amendments of 1990. Regulations covering Title V permits are found at 40 CFR 70. Operating permits are required for sources that are
How much of a pollutant must be emitted to be a major source depends on the pollutant and on the air quality in your State. In most cases, schools will not emit large enough amounts to be considered a major source. Consult with your State air pollution control agency or EPA regional office.
- major sources of Ambient Air Quality Standard pollutants,
- a major source of a hazardous air pollutant,
- covered by the acid precipitation provisions of the Clean Air Act, and
- sources regulated under certain programs of a State implementation plan.
In addition to the operating permit program, each State has its own air permit program for smaller sources of air pollution. You should be familiar with requirements for your State as well.
Note: This checklist does not include any regulations dealing with the regulation of emissions from industrial boilers or from power generation.
Ambient Air Quality Standards
The EPA has maximum emission concentrations that must not be exceeded for suspended particulate matter, sulfur dioxide, carbon monoxide, ozone, lead, and nitrogen dioxide. These can be found in Title 40, Part 50 of the Code of Federal Regulations [40 CFR 50].
Hazardous Air Pollutants
Title III of the Clean Air Act Amendments of 1990 [U.S.C. 7401 et seq.] contains a list of 189 hazardous air pollutants (HAPS). These substances require state-of-the-art emission-reduction systems because of their high toxicity, or other hazards associated with their use. In most cases, EPA considers an operation to be a major source of HAPS if it has the potential to emit 10 tons per year of any substance on that list. However, much lower emission concentrations may be required by State agencies. Your State may require registration or other actions, no matter how little is used in the school. Referral should be made to your State air pollution code. Two substances commonly used in Career-Technical schools that are on this list of toxic substances are trichloroethylene and tetrachloroethylene. For any hazardous or toxic material, the best solution is to substitute a less toxic substance whenever possible.
Operational Requirements
Requirements for diesel- and gasoline-powered vehicles are contained in 40 CFR parts 85 and 86. Degreasing, spray booths, surface coating, graphic arts, and volatile organic compounds (VOC) dry cleaning requirements are contained in 40 CFR part 60. Requirements for processes using one or more of the HAPS, including dry cleaning and degreasing with halogenated solvents, are contained in 40 CFR part 83. Persons involved in these activities should review the regulations and contact their EPA regional office for clarification.
Enforcement and Penalties
Violations of air pollution control regulations may involve civil or criminal penalties. Penalties for violations of any of the regulations are contained in Title VII of the Clean Air Act Amendments of 1990. Legal liability may also result from violations of applicable State air pollution regulations.

Definitions:
Ambient air quality standard: a limit on the concentration of a contaminant in the general outdoor atmosphere. The standard cannot be exceeded without (1) causing or tending to cause injury to human health, welfare, animal or plant life, or property, or (2) unreasonably interfering with the enjoyment of life and property, excluding all aspects of employer-employee relationship as to health and safety hazards.
Freeboard ratio: a ratio of the freeboard height to the tank width or narrower dimension at the tank lip.
Surface cleaner: a device to remove unwanted foreign matter from the surfaces of materials by using VOC solvents in the liquid or vapor state.
Suspended particulate matter: any solid or liquid matter dispersed in the outdoor atmosphere.
