For the purposes of this chapter, the following definitions shall apply unless the context indicates or requires a different meaning. Terms not defined herein shall be construed in accordance with customary usage.
BEST MANAGEMENT PRACTICES (BMP’s).
(1) 
Methods that have been determined to be the most effective, practical means of preventing or reducing pollution from nonpoint sources, such as pollutants carried by urban runoff. These methods can be structural (e.g., devices, ponds, engineered or constructed to prevent or manage stormwater) or nonstructural (e.g., policies to reduce imperviousness). BMP’s classified as “nonstructural” are those that rely predominantly on behavioral changes rather than construction in order to be effective. “Structural” BMP’s are engineered or constructed to prevent or manage stormwater.
(2) 
BMP’s also include schedules of activities, prohibitions of practices, maintenance procedures, and other management practices to prevent or reduce the pollution of waters of the United States. BMP’s also include treatment requirements, operating procedures, and practices to control plant site runoff, spillage or leaks, sludge or waste disposal, or drainage from raw material storage.
