The technical measures or best management practices which can be used to abate nonpoint source (NPS) pollution are improving, and states and local governments are employing them to address a wide variety of NPS problems. At the same time, resources for NPS programs at all levels remain relatively static. Because some states and localities have developed particularly effective methods for funding NPS programs and have thereby increased the Nation's capacity to utilize BMPs to control NPS pollution, EPA has sought the cooperation of several state and local agencies to assist in the development of case studies and related materials on NPS funding. These case studies demonstrate a variety of effective techniques which are currently being used by state and local governments to fund NPS programs.
