  2. Toxicity characteristic leaching procedure - Wikipedia

    en.wikipedia.org/wiki/Toxicity_characteristic...

    Toxicity characteristic leaching procedure (TCLP) is a soil sample extraction method for chemical analysis employed as an analytical method to simulate leaching through a landfill. The testing methodology is used to determine if a waste is characteristically hazardous, i.e., classified as one of the "D" listed wastes by the U.S. Environmental ...

  3. Maximum acceptable toxicant concentration - Wikipedia

    en.wikipedia.org/wiki/Maximum_Acceptable...

    Standard methods are designed and used widely to maximize precision and accuracy for all toxicity tests. Values derived from toxicity tests such as the MATC are reported to regulatory organizations like the US EPA and Environment Canada so more confident regulations can be designed. [citation needed]

  4. EPA Methods - Wikipedia

    en.wikipedia.org/wiki/EPA_Methods

    The United States Environmental Protection Agency (EPA) maintains and approves test methods, which are approved procedures for measuring the presence and concentration of physical, chemical and biological contaminants; evaluating properties, such as toxic properties, of chemical substances; or measuring the effects of substances under various conditions.

    Standards for performing a Phase I site assessment have been promulgated by the US EPA [1] and are based in part on ASTM in Standard E1527-13. [ 2 ] If a site is considered contaminated, a Phase II environmental site assessment may be conducted, ASTM test E1903, a more detailed investigation involving chemical analysis for hazardous substances ...

  6. Effluent guidelines - Wikipedia

    en.wikipedia.org/wiki/Effluent_guidelines

    The United States Environmental Protection Agency (EPA) issues Effluent Guideline regulations for categories of industrial sources of water pollution under Title III of the Clean Water Act (CWA). [1] The standards are technology-based, i.e. they are based on the performance of treatment and control technologies (e.g., Best Available Technology ...

  7. Best available technology - Wikipedia

    en.wikipedia.org/wiki/Best_Available_Technology

    In the development of the effluent standards, the BAT concept is a "model" technology rather than a specific regulatory requirement. The U.S. Environmental Protection Agency (EPA) identifies a particular model technology for an industry, and then writes a regulatory performance standard based on the model. The performance standard is typically ...

  8. National Emissions Standards for Hazardous Air Pollutants

    en.wikipedia.org/wiki/National_Emissions...

    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.
