The economic impact of current approaches to air pollution control is emissions taxes, and the most effective are marginal abatements. These are fines that are calculated as a percentage of the amount released by an industry into an air shed, local landfill or waterway. The most effective control approaches are implemented in a regulatory policy with execution time limits and enforcement mechanisms. Differences exist in control measures imposed across altered levels of provincial (city, county), national, regional, and state regimes. Nationally established air pollution regulations ensure maximum benefit while minimizing emphasis on margin and competition. An Environmental Protection Agency requirement is to cite manufacturing facilities that may introduce pollutants into the air or public waters. It is effective because the Environmental Protection Agency works closely with state and local governments in its pollution control efforts. State and local governments pass individual laws and regulations that meet or exceed the requirements of federal laws such as the Clean Air Act, Clean Water Act, RCRA, and CERCLA. The Environmental Protection Agency supervises state enforcement activities. It provides support to state officials and participates directly in major enforcement actions against violators of green regulations. "The Environmental Protection Agency (EPA) works with other federal environmental enforcement agencies, which require other federal agencies to pursue environmentally sound policies and to prepare an environmental impact statement (EIS) before undertaking any important action that significantly affects the environment." (EPA, pp.25-26, 1989-1991) The goal of each control approach is toward... half of the document... developing innovative products. Regulation is a compromise between conflicting public and industry interests, as well as bureaucratic/governmental objectives, which generates a rather uneven deregulation consequence.Works CitedEPA.
