• Suggested BMPs 1.Water should be sprayed throughout the site to help control wind blowing of fine materials such as soil, concrete dust,and paint chips.The amount of water must be controlled so that runoff from the site does not occur,yet dust control is achieved. Oils must never be used for dust control. 2. If possible,a wall should be constructed to prevent stray building materials and dust from escaping the area during demolition. 3. Schedule demolition to take place at a dry time of the year.
