Environmental Regulations (CFR title 40)
Clean Air Act
The Division of Environmental Services enforces the Environmental Protection Agency’s (EPA) mission to protect human health and the environment. To achieve this mission the EPA implements a variety of programs under the Clean Air Act that focus on:
- reducing outdoor, or ambient, concentrations of air pollutants that cause smog, haze, acid rain, and other problems
- reducing emissions of toxic air pollutants that are known to, or are suspected of, causing cancer or other serious health effects
- phasing out production and use of chemicals that destroy stratospheric ozone
These pollutants come from stationary sources (like chemical plants, gas stations, and powerplants) and mobile sources (like cars, trucks, and planes).

Maximum Achievable Control Technology (40 CFR 63)
The Maximum Achievable Control Technology (MACT) is a level of control that was introduced by Title III of the 1990 Clean Air Act Amendments. The purpose of these Amendments was to expedite the development of standards that would reduce HAP emissions.

Air Toxics
Toxic air pollutants, also known as hazardous air pollutants, are those pollutants that are known or suspected to cause cancer or other serious health effects, such as reproductive effects or birth defects, or adverse environmental effects. EPA is working with state, local, and tribal governments to reduce air toxics releases of over 200 pollutants to the environment. Examples of toxic air pollutants include benzene, which is found in gasoline; perchlorethlyene, which is emitted from some dry cleaning facilities; and methylene chloride, which is used as a solvent and paint stripper by a number of industries. Examples of other listed air toxics include dioxin, asbestos, toluene, and metals such as cadmium, mercury, chromium, and lead compounds.
