Regulatory Analysis

There are a variety of air regulations that may impact a facility, depending on its location and type. Air regulations may come from the federal government and state, local, or tribal governments. It is important to stay up-to-date on air regulations, as they come from multiple regulatory agencies and they can change often.


The National Emission Standards for Hazardous Air Pollutants (NESHAP) and the New Source Performance Standards (NSPS) are two sets of regulations promulgated by the EPA under the authority of the Clean Air Act. The NESHAP establish maximum emission levels for hazardous air pollutants (HAP) which are known or suspected to cause cancer or other serious health effects, such as reproductive effects or birth defects, or adverse environmental effects. The NSPS establish emission standards for new, modified, and reconstructed stationary sources within specific industrial categories. Both standards are designed to protect public health and the environment from the impacts of air pollution.

State, local, and tribal governments may also regulate air emissions. Many states have adopted air quality regulations that are more stringent than the federal rules. Currently, we follow the state-level regulations in the western United States to identify the changes that may impact our clients.
