Vehicle and Equipment Fueling A. Description and Purpose: 1. Vehicle equipment fueling procedures and practices are designed to prevent fuel sills and Jeaks, and reduce or eliminate contamination of stormwater. This can be accomplished by using offsite facilities, fueling in designated areas only, enclosing or covering stored fuel, implementing spill controls, and training employees and subcontractors in proper fueling procedures. B. Limitations: 1. Onsite vehicle and equipment fuelin should only be used where i is impractical to send vehicles and equipment offsite for fueling. Sen ing vehicles and equipment offsite should be done in conjunction with a Stabilized Construction Entrance 7 Exit. C. Implementation: 1. Use offsite fueling tations as much as ossible. These businesses are better equipped to handle fuel and spills properly. Per €orming this work offsite can also be economical by eliminating the need for a separate fueling area of o site. 2. Discourage *topping -off* of fuel tanks. 3. Absorbent spill cleanup materials and spill kits should be available in fueling areas and on fueling trucks, and should be disposed of properly after use. 4. Drip ans or absorbent pads should be used during vehicle and equipment fueling, unless the fueling is performed over an impermeable surface in a dedicated fueling area. 5. Use absorbent materials on small spills. Do not -tiose down or bury the spill. Remove the adsorbent materials promptly and dispose of properly. 6. Avoid mobile fueling of mobile construction equipment around the site; rather, transport the equipment to designated fueling areas. 7. Train employees and subcontractors in proper fueling and cleanup procedures. 8. Dedicated fueling areas should be protected from, stormwater runon and runoff, and should be located at least 50 ft away from downstream drainage facilities and watercourses. Fueling must be performed on level grode areas. 9. Protect fueling areas with berms and dikes to prevent runon, runoff, and to contain spills. 10. Nozzles used in vehicle and equipment fueling should be equipped with an automatic shutoff to control drips. Fueling operations should not be left unattended. 11. Federal, state, and local requirements should be observed for any stationary above ground storage tanks. 11. inspection and Maintenance A. Vehicles and equipment should be inspected each day of use for leaks. Leaks should be repaired immediately or problem vehicles or equipment should be removed from the project site. B. Keep omple supplies of spill cleanup materials onsite. C. Immediately clean up spills and properly dispose of contaminated soils. III. Solid Waste Management A. Description of Purpose: 1. Solid waste management procedures and practices. are designed to prevent or reduce the discharge of pollutants to stormwater from solid or construction waste by providing designated waste collection areas and containers, arranging for regular disposal, and training employees and subcontractors. B. Suitable Applications: 1. This BMP is suitable for construction sites where the following wastes are generated or stored: o. Solid waste generat,ed from trees and shrubs removed during land clearing, demolition of existing structures trubble), and building construction. b. Packaging materiels including wood, paper, and plastic. c. Scrap or surplus building materials including scrap metals, rubber, plastic, gloss pieces and masonry products. d. Domestic wastes including food containers such as beverage cans, coffee cups, paper bags, plastic wrappers, and cigarettes. e. Construction wastes including brick, mortar, timber, steel and metal scraps, pipe and electrical cuttings non hozordous equipment parts, Styrofoam and other materials send transport and package construction materials. C. Implementation: 1. The following steps will help keep a clean site and reduce stormwater pollution: a. Select designated waste collection areas onsite. b. inform trash- hauling contractors that you will accept only watertight dumpsters for onsite use. c. Inspect dumpsters for leaks and repair any dumpster that is not watertight. d. Provide an adequate number of containers with lids or covers that can be placed over the container to keep rain out or to prevent loss of wastes when it is windy. e. Plan for additional containers and more frequent pickup during the demolition phase of construction. f. t„ elect site trash daily, especially during rainy and windy conditions. g. Remove this solid waste promptly since erosion and sediment control devices tend to collect litter. h. Make sure that toxic liquid stes (sued ,oils, not i oils, solvents, and paints) and chemicals (acids, pesticides, i iv curing compounds) are of d s osed of dumpsters rs d i red for construction ri s. add t es, cu p p p e es g debris. 1 Do not hose out dumpsters on the construction site. Leave dumpster cleaning to the trash hauling contractor. j. for regular waste collection before containers overflow. k. Clean up immediately if a container does spill. 1. Make sure that construction waste is collected, removed and disposed of onl at authorized disposal teas. Solid waste storage areas should be located at least 50 ft from drainage facilities and and should not be located in areas prone to flooding or ponding. D. Inspection and Maintenance: 1. Insect and verify that, activity based BMPs are in place prior to the commencement of associated activities. While activities associated with the BMP are under way, inspect weekly to verify continued BMP implementation. 2. inspect BMPs subject to non stormwater discharge daily while non stormwater discharges occur. 3. Inspect construction waste area regularly. 4. Arrange for regular waste collection. IV. Concrete Washout A. The following steps will help reduce stormwater pollution from concrete wastes: 1. Discuss the concrete management techniques described in this BMP (such as handling of concrete waste and washout) with the reddy -mix concrete supplier before any deliveries are made. 2. Incorporate requirements for concrete waste management into material supplier and subcontractor agreements. 3. Store dry and wet materials under cover, away from drainage areas. 4. Avoid mixing excess amounts of fresh concrete. 5. Perform washout of concrete trucks offsite or in designed areas only. 6. Do not wash out concrete trucks into storm droins open ditches, streets, or streams. 7. Do not allow excess concrete to be duped onsite, except in designed areas. B. For onsite washout: 1. Locate washout areas of least 50 ft from storm drains, open ditches, or water bodies. 2. Do not allow runoff from this area by constructing o temporary pit or bermed area large enough for liquid and solid waste. 3. Wash out wastes into the temporary pit where the concrete con set, be broken up, and then disposed properly. 4. Avoid creating runoff by drinking water to a bermed or level area when washing concrete to remove fine particles and expose the oggregate. 5. Do not wash sweepings form exposed aggregate concrete into the street or storm drain. Collect and retum sweepings to aggregate base stockpile or dispose in the trash. V. Cleanup Parameters A. The Developer Homeowners Association shall be continually kept informed maintain lists of qualified contractors and available Vac- trucks, tank pumpers and other equipment readily accessible for clean -up operations. In addition, a continually updated list of ovailable absorbent materials and clean -up supplies should be kept on site. B. All maintenance personnel will be mode aware of techniques for prevention of spills. They will be informed of the requirements and procedures outlined in this lan. They will be kept abreast of current developments or new information on the prevention of spills and this plan. necessary alterations to this plan. C. When spills occur which could endanger human life and this becomes primary concern, the discharge of the life saving protection function will be carried out by the local police and fire departments. D. Absorbent materials, which are used in cleaning up spilled materials, will be disposed of in a manner subject to watercourses the approval of the Indiana Department of nvironmental Management. E. Flushing of spilled material with water will not be permitted unless so authorized by the Indiana Deportment of Environmental Management.
