The addition of lime can affect the pH (or acidiry) of runoff, which can adversely affect nearby sensitive surface waters. f'mportation oftopsoil is preferred o��er heavily liming and fertilizing exposed subsoil. 4-2.1.4 B11� C1.40 SOLID WASTE HANDLING AND DISPOSAL Solid waste is one of the major pollutants resultin¢ from construction. It is generated from trees and shrubs removed durine� land clearing and human and building waste during the installation of structures. The following practices control and reduce solid waste on construction sites: - Provide adequate disposal facilities on the construction site. - Remove and dispose of collected solid waste at authorized disposal areas. - Label waste containers and locate them in a covered area. Keep lids closed at all times. - Salvage and recycle an,y useful materials. - Conveniently locate and maintain sanitary facilities. - Selectively remove trees and other beneficial vegetation. 4-2.1.5 BMP C1.50 USE OF CHEhiICALS/:iAZARDOUS PRODUCTS DURING CONSTRUCTION Many types of chemicals may be used during construction activities. These chemical poliutants include paints, acids for cleaning masonry surfaces, cleaning solvents, asphalt products, soil additives used for stabilization and other purposes, concrete-curing compounds, and many others. These materials can be carcied by sediment and runoff from construction sites. A large percentage of these pollutants can be effectively controlled through implementation of source control soil erosion and sediment control practices. By using onl� the recommended amounts of these materials and applying them in a proper manner, pollution can be further reduced. As in the case of other pollutants, good housekeeping is the most important means of controlling pollution. The correct method of disposal of wastes varies with the material. Wash-up waters from water-based paints may go into a sanitary sewer, but wa�tes from oil-based paints, cleaning solvents, thinners, and mineral spirits must be disposed of through a licensed waste management firtn or treatnent, storage and disposal company. Disposal of concrete products, additives, and curing compounds depends on the product. Infortnation is available from the local healtn department or the Hazardous Substance Information Hotline (1-800-633-7585). The following are guidelines for managing hazardous products: - Buy and use only what is needed. Store, re-use, give away, recycle, or dispose of leftovers safely. Read and follow directions on the label. Hazardous products may be labeled as any one or more oF the followine: Danger Poisonous Volatile Combustible Caustic Explosivc Warnin� Corrosive Flammable Caution Keep products in their original containers whenever possible. If the product must he transferred to smaller container:�, use the propr�r size funnel and avoid spifls. Label all container:;. - Prevent labels frorn falling off ds�e to weathering by covering the label with transparent tape. To re- label, r�se a metal tag att�iched to the container or use a stencil and spray paint. 4-2-3
