5. Potential Sources of Pollutants Potential sources of sediment to water runoff: Clearing and grubbing operations • Grading and site excavation operations • Vehicle tracking • Topsoil stripping and stockpiling • Landscaping operations • Potential pollutants and sources, than sediment, to storm water runoff: Combined Staging Area—small fueling activities, minor equipment maintenance, sanitary • facilities, and hazardous waste storage. Materials Storage Area—general building materials, solvents, adhesives, paving materials, • paints, aggregates, and so on. Construction Activity—paving, curb/gutter installation, concrete pouring/mortar/stucco, and • building construction Concrete Washout Area • For all potential construction site pollutants, see 2 below. Table 2. Potential construction site pollutants. Circle all that applies to your site and in the last column identify pollution prevention measures to minimize their discharge. Material/Chemical Storm Water Pollutants Common Location* Pollution Prevention Methods Chlorinated Pesticides (insecticides, hydrocarbons, Herbicides used for fungicides, herbicides, organophosphates, noxious weed control rodenticide) carbamates, arsenic Fertilizer Nitrogen, phosphorous Newly seeded areas Calcium sulphate, calcium Plaster Building construction carbonate, sulfuric acid Perchloroethylene, No equipment methylene chloride, Cleaning solvents cleaning allowed in trichloroethylene, project limits petroleum distillates Asphalt Oil, petroleum distillates Streets and roofing Limestone, sand, pH, Curb and gutter, Concrete chromium building construction Glue, adhesives Polymers, epoxies Building construction Metal oxides, Stoddard Paints solvent, talc, calcium Building construction carbonate, arsenic Curing compounds Naphtha Curb and gutter
