Clean Air Act Amendments of 1970



This legislation required the Environmental Protection Agency (EPA) to develop and enforce regulations to protect the general public from exposure to airborne contaminants that are known to be hazardous to human health. This law is an amendment to the Clean Air Act originally passed in 1963. In accordance with Sections 111 and 112 of the CAA, EPA established New Source Performance Standards (NSPS) and National Emissions Standards for Hazardous Air Pollutants (NESHAP) to protect the public.

How BNL Complies

The National Emission Standards for Hazardous Air Pollutants (NESHAPs), a subpart of the federal Clean Air Act (CAA), regulates the release of airborne radioactive materials to the environment. This regulation establishes permitting, monitoring, reporting, and public dose limit requirements for air emission sources. The NESHAPs regulations are administered and enforced by the U.S. Environmental Protection Agency. Under NESHAPs, the Laboratory must demonstrate on an annual basis that no member of the public has received a radiological dose greater than 10 mrem from Laboratory air emissions. All Laboratory sources of airborne radioactive material must be identified and assessed, regardless of the quantity involved. Examples of sources that must be identified and assessed include point sources such as reactor stacks, diffuse sources such as liquid holding ponds, and bench-top radioisotope work conducted in ventilation hoods.
