Best Management Practices

What are Best Management Practices or BMP’s? According to our ordinances, BMP’s are:

a “schedule of activities, pollution treatment practices or devices, prohibitions of practices, general good housekeeping practices, pollution prevention and educational practices, maintenance procedures, and other management practices or devices to prevent or reduce the discharge of pollutants directly or indirectly to storm water, receiving waters, or storm conveyance system. Best Management Practices also include but are not limited to treatment practices, operating procedures, and practices to control site runoff, spillage or leaks, sludge or water disposal, or drainage from raw materials storage.”

At the very minimum, construction sites are required to implement the following Best Management Practices in order to prevent storm water pollution. Construction sites classified as high threat will have additional guidelines.
