of NPS and the differences from point source pollution indicated stricter and powerful control mechanism should be applied. Market-based approaches, design-based approaches, and command and control could be useful, and a policy tool combination or best suit tool depends on particular problem, local condition and policy goal, as well as costs and budget would be desired. The ultimate goal for controlling nonpoint pollution is to maximize environmental benefits, especially in some environmental sensitive areas, degraded areas, critical habitats for endangered species. The baseline for nonpoint pollution abatement should be attending acceptable water quality. Collaboration among agencies is necessary. Federal agencies involved in nonpoint pollution control include the Natural Resources Conservation Service, US Forest Service, Office of Surface Mining Reclamation and Enforcement, Bureau of Land Management and the Army Corps of Engineers. Effective management of NPS pollution requires a partnership among state, federal, local agencies as well as private interests and the public. Coordination among existing programs, especially governmental spending programs, should be performance objectives. Examples of coordination include the federal Clean Water State Revolving Fund and governmental spending programs under the CWA and the Farm Bill References External links Regulations in Canada Non-point water pollution primer (Ohio) Diffuse source pollution regulation in New South Wales, Australia Environmental law in the United States Environmental issues with water Water pollution in the United States
