Working in conjunction with states, tribes, and local governments, the staff of the U.S. Environmental Protection Agencys (EPAs) national enforcement and compliance assurance program ensures compliance with the nations environmental laws. The national enforcement and compliance assurance program staff are located in EPAs Office of Enforcement and Compliance Assurance (OECA) and in the EPA regional and satellite offices. Our mission is to protect the well-being of all Americans, our nations environment, and its natural resources. By pursuing a strategic approach in which we systematically identify problems and adopt the appropriate tools to address their risks, EPA and the states, tribes, and local governments seek to maximize compliance and reduce threats to public health and the environment. In response to the Government Performance and Results Act (GPRA), which promotes more results-based management, EPA developed a strategic plan that delineates specific goals, objectives, and performance measurements. Goal 9 of the strategic plan requires EPA to provide a credible deterrent to pollution and greater compliance with the law. Goal 9 is the core responsibility of the national enforcement and compliance assurance program.
