The EPA has developed a software program named "TANKS" which performs the Chapter 7 methodology for calculating emission losses from storage tanks. The program's installer file along with a user manual, and the source code are available on the Internet.
For each listed source category, EPA indicates whether the sources are considered to be major sources or area sources. The 1990 Clean Air Act Amendments direct EPA to set standards for all major sources of air toxics, and for some area sources that are of particular concern. EPA is required to review all source category regulations every eight ...
New Source Performance Standards (NSPS) are pollution control standards issued by the United States Environmental Protection Agency (EPA). The term is used in the Clean Air Act Extension of 1970 (CAA) to refer to air pollution emission standards, and in the Clean Water Act (CWA) referring to standards for water pollution discharges of industrial wastewater to surface waters.

The EPA uses a formula to calculate AQI values — it doesn't simply add up the impact of each pollutant. The AQI uses a scale that typically ranges from zero to 500 to denote air quality.
Through the Tailoring Rule, EPA raised the major source regulatory threshold for GHGs from the 100/250 ton per year levels to 100,000 tons per year of CO 2 equivalent emissions. In a 5-4 decision authored by Justice Scalia, the Supreme Court remanded the Tailoring Rule to EPA on the grounds that the Clean Air Act did not authorize the agency to ...
The amount of pollutants allowed for certain new sources is defined by the EPA's New Source Performance Standards (NSPRS). A stationary source in air quality terminology is any fixed emitter of air pollutants, such as fossil fuel burning power plants, petroleum refineries, petrochemical plants, food processing plants and other heavy industrial ...
