Florida Erosion and Sediment Control Inspector's Manual 2) Equipment Maintenance and Repair r Maintenance and repair of construction machinery and equipment should be confined to areas specifically designated for that purpose . Such areas should be located and designed so that oils , gasoline , grease , solvents and other potential pollutants cannot be washed directly into receiving streams , stormwater conveyance systems, or existing and potential wellfields . These areas should be provided with adequate waste disposal receptacles for liquid and solid wastes. Maintenance areas should be inspected and cleaned daily. On a construction site where designated equipment maintenance areas are not feasible , exceptional care should be taken during each individual repair or maintenance operation to prevent potential pollutants from becoming available to be washed into streams or conveyance systems . Temporary waste disposal receptacles should be provided and emptied as required . 3) Storm Sewer Inlet Protection Inlets to storm sewers should be protected by suitable filtering devices during construction to keep pollutants from entering conveyance systems . See STORM DRAIN INLET PROTECTION - Section 4 .08 (ES BMP 1 . 08) . 4) Waste Collection and Disposal A plan should be formulated for the collection and disposal of waste materials on a construction site . Such a plan should designate locations for trash and waste receptacles and establish a specific collection schedule . Methods for ultimate disposal of waste should be specified and carried out according to applicable local and state health and safety regulations . Special provisions should be made for the collection , storage , and disposal of liquid wastes and toxic or hazardous materials . Receptacles and other waste collection areas should be kept neat and orderly to the extent .. possible . Trash cans should have lids and dumpsters should have covers to prevent rainwater from entering . Waste should not be allowed to overflow its container or accumulate for excessively long periods of time . Trash collection points should be located where they will least likely be affected by concentrated stormwater runoff. 5) Demolition Areas Demolition projects usually generate large amounts of dust with significant concentrations of heavy metals and other toxic pollutants . Dust control techniques should be used to limit the transport of the airborne pollutants . However, water or slurry used to control dust should be retained on the site and not be allowed to run directly into watercourses or stormwater conveyance systems . 6) Washing Areas Vehicles such as cement or dump trucks and other construction equipment should not be washed at locations where the runoff will flow directly into a watercourse or stormwater 4-4 •
