I· I f I,: If I a (i) potential discharge of pollu~ts from construction activities. As with sediment, the vast majority of all pollutants are earned into the r~ving waters Via storm runoff. The amount of runoff coming from a.construction ·site is dependent upon hydrologic factOTS. These include the amount, intensity, and frequency of rai:pfall; the infiltration rate of the soil; surface roughness; and the length and' steepness of the groUnd slope. Large areas which have been denuded or stripped of vegetation, long slopes, steep slopes, compacted solls, and high intensity "-#.~. _an are all factors conducive to increased runoff. The following information summarizes the nature and control of various construction- relating pollutants, other than sediment. JtJ-t..t.v()Z po')r' Cy"jv~~IJ,J ( , Solvents Construction activity often uses solvents for de-greasing and cleaning machinery and machinery parts. For roofing activity, residual tars and sealing compoUnds, spent solvents, kerosene, and soap cleaners may be produced. for sheet metal activity, small quantities of acid and solvent 'cleaners such as .kerosene, metal shavings, adhesive residues md enamel coatings may be produced. Solvents which .become waste material are classified as dangerous waste. . . Recommended Control Best.Management Practices (BMPs): Solvents. and solvent- associated wastes will: 'be stored in containers.

Wash water may ,require treatment before it can he discharged to the sewer. ' • Replace ~hlorinated organic solvents (l,l,l~trichloroet:haJle, methylene chloride, etc,) with nonchlorinated splvents. Nonchlormated solv;ents, such as kerosene or niliteral spirits, are less toxic and less e~nsive to dispose' of. Check the list of active ingredients to see whether it contains ~hlorinated solvents. (The "chlor" tel'ID; indicated that the solvent 'is chlorinated.) • Choose cleaning agents that can be recycled C:lMy DIXlI1IIJllIIls\1S2.10SWP.doc , . (viii) • '0, " ~ ! ;; l' • ~" I e . ' ;::"".,.'. Paints Painting contractors will generate paint and other finishing residues, spent th4mets;' at:J.d pan"t cOntainers. Paint is a chemical pollutant containing hazardous metallic plgthents or biocides and is carried by sediment and runoff from construction sites. . Recommended Control BMPS: A large percentage' ofthispallutant can be etfeQtively Controlled through implementation of source control soil erosion and se4ime~tation control practices. As in the case of other pollutants, good housekeeping is the most important means of controlling pollution. The correct method of' waste disposal varies with the material. Wash-up wastes from water .. based paints may go into a sanitary sewer" but wastes from oil-based' paints, cleaning solvents, thinners, and mineral spirits must be disposed of,through a licensed waste management firm. Other source control BMPs include: • • Use tarps and vacuums to collect solid wastes produced by sanding or painting . Tarps, drip pans or other spill collection devices should. be used to collect spills of paints, solvents or other liquid materials. These wastes should be disposed of properly to keep them from contaminating stOnD. water. . As little as 30 percent of the pamt may reach ,the target from conventional airless spray guns; tl\e rest is lost as overspray. Paint solids from overSpray ~e deposited on the ground where they can contaminate storm water. Other ~pray equipment that delivers more paint to the target and less overspray should be used such as: Electrostatic spray equipment, air-atomized spray guns, high-volume/low- pressure spray guns, amid gravity-feed guns. Treated Wood Products This group includes wood products such as cut wood, treated wood, and where cutting equipment is employed where the by-products are chips and sawdust. The timber is typically moved by hand after being deposited by truck Other wastes include wood and paper from packaging and building materials. Recommended Control BMPs: The major control mechanism for these pollutants is to , provide adequate disposal facilities. Collected wood waste should be removed and disposed of at authorized disposal areas. Frequent garbage removal helps maintain construction sites in a clean and attractive manner. Source control BMPs, sUch as good housekeeping , should always be used to control storm water pollution. Outside areas where treated wood products are stored should be located where storm runofftbrough the area is minimal. • Where possible, store material on a paved area, which is sloped, so that pooling .dOc -~: .'~' .

At a minimum, sandbag dikes, sih fences, straw bale dikes, or equivalent . controls practices are required for all significant sideslope and downslope boundaries of the construction area.
