The unlawful discharge of contaminants, including industrial chemicals, sewage, agricultural runoff or oil, into rivers, lakes, groundwater or coastal waters, in violation of environmental protection statutes that set permissible discharge limits. It is prosecuted both as a regulatory offense against a permit or licensing regime and, when the discharge is deliberate, concealed or causes significant environmental or public health harm, as a more serious environmental crime carrying criminal penalties. Major legal frameworks addressing it include the United States Clean Water Act of 1972 and the European Union's Water Framework Directive.
Facts
Classification CodeWater pollution is chiefly regulated in United States law through the Clean Water Act, which defines a point source for regulatory enforcement purposes; Congress amended that definition in 1987 to bring municipal storm sewer systems and industrial storm water, such as runoff from construction sites, within the Act's reach. 1 Typical PenaltyClean Water Act penalties are tiered: a first offense of criminal negligence carries a minimum fine of $2,500 and a maximum of $25,000 per day of violation, plus up to a year in jail, a second such offense raises the maximum fine to $50,000 per day, and a civil violation exposes the violator to a penalty the EPA can currently seek up to $66,712 per violation per day. 1 Elements of OffenseLiability for an unlawful discharge under the Clean Water Act turns on whether the discharge issues from a point source, a term the Act itself defines for regulatory enforcement purposes, since only a discharge of pollutants from a point source into navigable waters requires a permit under the Act's discharge permitting system. 1 Notable ExampleCleveland's Cuyahoga River caught fire on June 22, 1969, when a spark from a passing rail car ignited an oil slick on the water; the fire, together with the Santa Barbara oil spill that same year, helped spur an avalanche of water pollution control activity, including amendments extending the Clean Water Act and the creation of the federal Environmental Protection Agency. 2 Jurisdiction VariationAdministration of the Clean Water Act's discharge permits varies by state: the Environmental Protection Agency has authorized 47 states to issue National Pollutant Discharge Elimination System permits directly to the facilities they regulate, with the remaining states' facilities permitted by EPA regional offices instead. 1 Classification
