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 ...
The CWQG's long and short-term exposure concentrations are derived in a similar way as the methods used by the US EPA, and are the CMC or CCC equivalents. [7] When an MATC is reported with toxicity tests, it has sometimes been called a threshold-observed-effect-concentration (TOEC).
Accidental release source terms are the mathematical equations that quantify the flow rate at which accidental releases of liquid or gaseous pollutants into the ambient environment which can occur at industrial facilities such as petroleum refineries, petrochemical plants, natural gas processing plants, oil and gas transportation pipelines, chemical plants, and many other industrial activities.
The methods in the Agency index are known as EPA Methods. [1] [2] There are other types of methods such as the ASTM and United States Pharmacopeia, but the EPA Methods are developed through a regulatory process involving public notice, comment and revision and are legally binding whereas ASTM methods are developed through a consensus process ...
Title 40 is a part of the United States Code of Federal Regulations.Title 40 arranges mainly environmental regulations that were promulgated by the US Environmental Protection Agency (EPA), based on the provisions of United States laws (statutes of the U.S. Federal Code).
The inventory was first proposed in a 1985 New York Times op-ed piece written by David Sarokin and Warren Muir, researchers for an environmental group, Inform, Inc. [2] Congress established TRI under Section 313 of the Emergency Planning and Community Right-to-Know Act of 1986 (EPCRA), and later expanded it in the Pollution Prevention Act of 1990 (PPA).
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 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 ).
