NEW JERSEY STORMWATER BEST MANAGEMENT PRACTICES (BMP) MANURAL or BMP MANUAL
The manual maintained by the Department providing, in part, design specifications, removal rates, calculation methods, and soil testing procedures approved by the Department as being capable of contributing to the achievement of the stormwater management standards specified in this chapter.
