© 2010 Pearson Education, Inc., publishing as Prentice-Hall 2 Environmental Protection Agency Created in 1970 to coordinate implementation and enforcement of federal environmental laws. –Broad rule-making powers –Adjudicative powers EPA can initiate judicial proceedings against suspected violators of federal environmental laws.

© 2010 Pearson Education, Inc., publishing as Prentice-Hall 3 National Environmental Policy Act Mandates that federal government must consider the adverse impact a federal government action would have on the environment before the action is implemented. –E.g., when new highway planned, or government considering licensing a nuclear power plant.

© 2010 Pearson Education, Inc., publishing as Prentice-Hall 4 Environmental Impact Statement Must be prepared for all federal action that significantly affects the quality of the human environment. To provide information about the environment so that government can determine feasibility of the project.

© 2010 Pearson Education, Inc., publishing as Prentice-Hall 5 Environmental Impact Statement (continued) EIS must: –Describe affected environment. –Describe impact of project. –Identify and discuss alternatives. –List resources to be committed. –Contain cost-benefit analysis. Subject to public review and comments. EPA decisions appealable to appropriate U.S. court of appeals.

© 2010 Pearson Education, Inc., publishing as Prentice-Hall 7 Pollution Sources Stationary Sources of Air Pollution Mobile Sources of Air Pollution Nonattainment Areas Toxic Air Pollutants

© 2010 Pearson Education, Inc., publishing as Prentice-Hall 8 Sources of Air Pollution Stationary sources –E.g., industrial plants, oil refineries, public utilities. –States must identify major sources and develop plans to reduce pollution. Mobile sources –Automobiles, airplanes, and other vehicles. –CAA sets emission standards, requires air pollution controls on vehicles.

© 2010 Pearson Education, Inc., publishing as Prentice-Hall 9 National Ambient Air Quality Standards EPA sets standards for certain pollutants. –E.g., carbon monoxide, lead, particulates. Standards set at two levels: –Primary – to protect human beings. –Secondary – to protect vegetation, matter, climate, visibility, and economic values. States responsible for enforcement. –Prepare state implementation plans. –Federal EPA monitors compliance.

© 2010 Pearson Education, Inc., publishing as Prentice-Hall 10 Nonattainment Areas Regions that do not meet air quality standards. –Five categories, ranging from marginal to extreme. States must submit compliance plans. –Failure to develop and implement approved plan will cause loss of highway funds and limitations on new sources of emissions.

© 2010 Pearson Education, Inc., publishing as Prentice-Hall 11 Clean Water Act First enacted in1948, amended several times. Provides comprehensive regulation of water quality. –Drinking water sources. –Recreational sources. –Agricultural and industrial uses. –Protection of fish and wildlife. Primarily enforced by states.

© 2010 Pearson Education, Inc., publishing as Prentice-Hall 12 Point Sources of Water Pollution Sources of water pollution such as paper mills, manufacturing plants, electric utility plants, and sewage plants. Dischargers must obtain permits, keep records, maintain monitoring equipment, and keep samples of discharge.

© 2010 Pearson Education, Inc., publishing as Prentice-Hall 13 Thermal Pollution CWA prohibits heated water or material discharged into waterways that upsets the ecological balance and decreases the oxygen content. Regulation of electric utility companies, manufacturing facilities to prevent.

© 2010 Pearson Education, Inc., publishing as Prentice-Hall 14 Wetlands Areas that are inundated or saturated by surface water or ground water that support vegetation typically adapted for life in such conditions. –E.g., swamps, marshes. CWA forbids filling or dredging of wetlands or navigable waters without permit from Army Corps of Engineers.

© 2010 Pearson Education, Inc., publishing as Prentice-Hall 15 Safe Drinking Water Act Authorizes the EPA to establish national primary drinking water standards. Prohibits the dumping of wastes into wells used for drinking water. States primarily responsible for enforcing the act.

© 2010 Pearson Education, Inc., publishing as Prentice-Hall 16 Ocean Protection Marine Protection, Research, and Sanctuaries Act –Extended environmental protection to the oceans. –Requires a permit for dumping wastes and other foreign materials into ocean waters. –Establishes marine sanctuaries in ocean waters and in the Great Lakes and their connecting waters.

© 2010 Pearson Education, Inc., publishing as Prentice-Hall 17 Oil Spills Oil Pollution Act of 1990 requires oil industry to adopt procedures and contingency plans. CWA authorizes the U.S. government to clean up oil spills and spills of other hazardous substances in ocean waters. –Government can recover cleanup costs from responsible parties.

© 2010 Pearson Education, Inc., publishing as Prentice-Hall 18 Toxic Substances Chemicals used for agricultural, industrial, and mining that cause injury to humans, birds, animals, fish, and vegetation. Key federal laws: –Insecticide, Fungicide, and Rodenticide Act (FIFRA) –Toxic Substances Control Act (TSCA)

© 2010 Pearson Education, Inc., publishing as Prentice-Hall 19 Toxic Substances Control Act EPA identifies toxic pollutants. –E.g., mercury, benzene. EPA sets standards for these chemicals without regard to economic or technological feasibility. EPA requires stationary sources to control emissions, manufacturers to test new chemicals; may limit manufacture or sale.

© 2010 Pearson Education, Inc., publishing as Prentice-Hall 20 Insecticides, Fungicides, and Rodenticides Products must registered with EPA before being sold. EPA may deny, suspend, or cancel registration. –E.g., DDT.

© 2010 Pearson Education, Inc., publishing as Prentice-Hall 21 Resource Conservation and Recovery Act (RCRA) Regulates hazardous waste: solid waste that may cause or significantly contribute to an increase in mortality or serious illness or pose a hazard to human health or the environment if improperly managed. Regulates facilities that generate, treat, store, transport, and dispose of hazardous wastes. States have primary responsibility for implementing standards established by the Act.

© 2010 Pearson Education, Inc., publishing as Prentice-Hall 22 Superfund Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). Administered by EPA. Gives the federal government a mandate to deal with hazardous wastes that have been spilled, stored, or abandoned.

© 2010 Pearson Education, Inc., publishing as Prentice-Hall 23 Superfund (continued) EPA identifies sites where hazardous wastes have been disposed, stored, abandoned, or spilled, and ranks these sites regarding the severity of risk. Sites remediated using money from responsible parties or money from Superfund. –Generator, transporter, former or current owner of site may be held liable. –Responsible parties liable without regard to fault.

© 2010 Pearson Education, Inc., publishing as Prentice-Hall 24 Radiation Pollution Emissions from radioactive wastes that can cause injury and death to humans and other life and can cause severe damage to the environment.

© 2010 Pearson Education, Inc., publishing as Prentice-Hall 25 Radiation Pollution (continued) EPA empowered to set standards for radioactivity in the environment and to regulate the disposal of radioactive waste. Regulates thermal pollution from nuclear power plants. Regulates emissions from uranium mines and mills.
