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 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 ...
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 ]
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 ...
Current CdTe modules pass the U.S. EPA's Toxicity Characteristic Leaching Procedure (TCLP) test, designed to assess the potential for long-term leaching of products disposed in landfills. [ 15 ] A document hosted by the U.S. National Institutes of Health [ 2 ] dated 2003 discloses the following:
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).
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.
In practical use, the cost aspect is also taken into account. [2] See also discussions on the topic of the precautionary principle which, along with considerations of best available technologies and cost-benefit analyses , is also involved in discussions leading to formulation of environmental policies and regulations (or opposition to same).
