A conventional pollutant is a term used in the USA to describe a water pollutant that is amenable to treatment by a municipal sewage treatment plant. A basic list of conventional pollutants is defined in the U.S. Clean Water Act. [1] The list has been amended in regulations issued by the Environmental Protection Agency: biochemical oxygen ...
Air pollution emission factors are usually expressed as the weight of the pollutant divided by a unit weight, volume, distance, or duration of the activity emitting the pollutant (e.g., kilograms of particulate matter emitted per megagram of coal burned). The factors help to estimate emissions from various sources of air pollution.
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 ...
This is a list of Superfund sites in Texas designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations.

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.
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.

At the POTW, harmful pollutants in domestic sewage, called conventional pollutants, are removed from the sewage and then the treated effluent is discharged into a surface water body. [38] The removed solids constitute sewage sludge, which typically receive further treatment prior to final disposal on land. (See Sewage sludge treatment.) POTWs ...
