The Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA), also known as "Superfund", requires that the criteria provided by the Hazard Ranking System (HRS) be used to make a list of national priorities of the known releases or threatened releases of hazardous substances, pollutants, or contaminants in the United States.

A map of Superfund sites as of October 2013. Red indicates currently on final National Priority List, yellow is proposed, green is deleted (usually meaning having been cleaned up). Superfund sites are polluted locations in the United States requiring a long-term response to clean up hazardous material contaminations. Sites include landfills ...
The 1977 CWA amendments provided a list of pollutant and pollutant groups to be considered by the agency in developing regulations. [8] EPA is also required to review and revise regulations as needed, and since 1972 it has promulgated ELGs for 59 industrial categories, with over 450 subcategories.
A Suspect List Exchange [38] (SLE) has been created to allow sharing of the many potential contaminants of emerging concern. The list contains more than 100,000 chemicals. Table 1 is a summary of emerging contaminants currently listed on one EPA website and a review article. Detailed use and health risk of commonly identified CECs are listed in ...
These sections require the EPA "(1) to list widespread air pollutants that reasonably may be expected to endanger public health or welfare; (2) to issue air quality criteria for them that assess the latest available scientific information on nature and effects of ambient exposure to them; (3) to set primary NAAQS to protect human health with ...
The National Emission Standards for Hazardous Air Pollutants (NESHAP) are air pollution standards issued by the United States Environmental Protection Agency (EPA). The standards, authorized by the Clean Air Act, are for pollutants not covered by the National Ambient Air Quality Standards (NAAQS) that may cause an increase in fatalities or in serious, irreversible, or incapacitating illness.
The US EPA is the governmental organization responsible for writing and enforcing environmental regulations passed by Congress. The Clean Water Act was passed in 1972. Section 304(a)(1) of the Clean Water Act is the Water Quality Criteria (WQC) developed for the protection of aquatic life and human health. [4]
EPA then published a clarified list, called the Priority Pollutant list, which is still widely used to develop NPDES permit requirements and related regulatory documents. EPA subsequently deleted 3 pollutants from the list, making the current total 126. As with the Toxic Pollutant list, the Priority Pollutant list is not exhaustive.
