Description of maintenance guidelines for proposed water quality measures See attached B$AP Operations and Maintenance Manual. ADDI11ONAL STORMWATER POLLUT]ON PREVEN110N MEASURES VEHICLE EQUIPMENT MAINTENANCL Description and Purpose Prevent or reduce the contamination of stormwoter resulting from vehicle and equipment maintenance by running o dry and clean site". The best option would be to perform maintenance activities at an offsite facility. If this option is not available then work should be performed in designated areas only, while prov cover for materials stored outside, check for leaks and spills, and containing and cleaning up spills immediately, Suitable Applications These procedures are suitable on all construction projects where an onsite yard area is necessary for storage and maintenance of heavy equipment and vehicles. Limitations Onsite vehicle and equipment maintenance should only be used where it is impractical to send vehicles and equipment offsite for maintenance and repair. Sending vehicles/equipment oftsite should be done in conjunction with o Stabilized Construction Entrance/Exit. Outdoor vehicle or equipment maintenance is o potentially significant source of stormwater poltution. Activities that can contaminate stormwater include engine repair and service, changing or replacement of fluids, and outdoor equipment storage and parking (engine fluid leaks) )rnplemeptoUon If maintenance must occur onsite, use designated areas, located away from drainage courses. Dedicated maintenance areas should be protected from stormwater runoni and runoff and should be located at least 50 ft from downstream drainage facilities and watercourses. Drip pans or absorbent pads should be used during vehicle and equipment maintenance work that involves fluids, unless the maintenance work is performed over an i mpermeable surface in a dedicated maintenance area. Place a stockpile of spill cleanup materials where it will be readily accessible. All fueling trucks and fueling areas are required to have spill kits and/or use other spill protection devices. Use adsorbent materials on small spills. Remove the absorbent materials promptly and dispose of properly, Inspect onsite vehicles and equipment daily at startup for leaks, and repair immediately. Keep vehicles and equipment clean; do not allow excessive build-up of oil and grease. Segregate and recycle wastes, such as greases, used oil or oil filters, antifreeze, cleaning solutions, automotive batteries, hydraulic and transmission fluids. Provide secondary containment and covers for these materials if stored onsite. Train employees and subcontractors in proper maintenance and spill cleanup procedures. Dr pans or plastic sheeting should be placed under all vehicles and equipment placed on cocks, barges, or other structures over water bodies when the vehicle or equipment is planned to be idle for more than 1 hour. Properly dispose of used oils, fluids, lubricants, and spill cleanup materiais. Do not place used oil in o dumpster or pour into o storm drain or watercourse. Properly dispose of or recycle used batteries. Do not bury used tires. Repair leaks of fluids and oil immediotely. L below is further information if you must perform vehicle or equipment maintenance onsite. inspection and Maintenance inspect and verify that 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. Keep ample supplies of spill cleanup materials onsite. Maintain waste fluid containers in leak proof condition. Vehicles and equipment should be inspected on each day of use. Leaks should be repaired i mmediately or the problem vehicle(s) or equipment should be removed from the project site. Inspect equipment for damaged hoses and leaky gaskets routinely. Repair or replace as needed. VPL:IC L AND ::u tEr.T F7[.LINC Description and Purpose Vehicle equipment fueling procedures and practices are designed to prevent fuel spills and leaks, and reduce or eliminate contamination of stormwater. This can be accomplished by using offsite facilities, fueling in designated areas on enclosing or covering stored fuel, implementing spill controls, and training employees and subcontractors in proper fueling procedures. Limitations Onsite vehicle and equipment fueling should only be used where it is impractical to send vehicles and equipment offsite for fueling. Sending vehicles and equipment oftsite shou be done in conjunction with a Stabilized Construction Entrance/ Exit. Implementation Use offsite fueling stations as much as possible. These businesses are better equipped to handle fuel and spills properly. Performing this work offsite can also be economical by eliminating the need for a separate fueling area at a site. Discourage "topping-off" of fuel tanks. 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. Drip pans 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. Use absorbent materials on small spills. Do not hose down or bury the spill. Remove the adsorbent materials promptly and dispose of properly. Avoid mobile fueling of mobile construction equipment around the site; rather, transport the equipment to designated fueling areas. Train employees and subcontractors in proper fueling and cleanup procedures. 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--grade areas. Protect fueling areas with berms and dikes to prevent runon, runoff, and to contain spills. Nozzles used in vehicle and equipment fueling should be equipped with an automatic shutoff to control drips. Fueling operations should not be left unattended. Federal, state, and local requirements should be observed for any stationary above ground storage tanks. Inspection and Maintenance Vehicles and equipment should be inspected each day of use for leaks. Leaks should be repaired immediately or prob vehicles or equipment should be removed from tbe project site. Keep ample supplies of spill cleanup materials onsite. Immediate clean up spills and properly dispose of contaminated soil and cleanup materials. 0 .212 lt"221: iyL1 7 .c Description and Purpose 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. Suitable Applications This BMP is suitable for construction sites where the following wastes are generated or stored: Solid waste generated from trees and shrubs removed during land clearing, demolition of existing structures (rubble), and building construction Packaging materials including wood, paper, and plastic Scrap or surplus building materials including scrap meta rubber, plastic, glass pieces and masonry products Domestic wastes including food containers such as beverage cons, coffee cups, paper bags, plastic wroppers, and cigarettes Construction wastes including brick, mortar, timber, steel and metol scraps, pipe and electrical cuttings, nonhazardous equipment parts, stofoam and other materials send transport and package cosstruction materials Im The folowing steps will help keep a clean site and reduce stormwater pollution: Select designated waste collection areas onsite. lriforrn trosh-hauling contractors that you will accept only watertight dumpsters for onsite use. Inspect iurnpsters for leaks and repair any dumpster that is not watertight. Provide an adequate number of containers with lids or covers that can be placed over the contair.er to keep rain out or to prevent loss of wastes when it is windy. Plan tor additional containers and more frequent pickup during the demolition phase of construction, Collect site trash daily, especially during rainy and windy conditions. Remove this solid waste promptly since erosion and sediment control devices tend to collect itter. Make s rht toxic liqud wastes (used oils, solvents, and points) and chemicals (acids, pesttcices, additives, curing compounds) are not disposed of in dumpsters designated for construct debr Do not hose out dumpsters on the construction site. Leave dumpster cleaning to the trash hauling contractor. Arrang for regulor waste collection before containers overflow. Clean up immediately if a container does spill. Make sure that construction waste is collected, removed, and disposed of only at authorized disposci areas. Co}iector:, Storage, and Disposal Littering on the project site should be prohibited To prevent ccgging of the storm drainage system, litter and debris removal from drainage grates, trosri racks, and ditch lines should be a priority. Trash receptacles should be provided in the contractors yard, field trailer areas, and at locations where workers congregate for lunch and break periods. Litter from work areas within the construction limits of the project site should be collected and aed ir: watertight dumpsters at least weekly, regardless of whether the litter was qeneraied by he contractor, the public, or others Collected litter and debris should not be placed in or next to drain inlets, stormwater drainage systems, or watercourses. Durnpsrers of sutficient size and number should be provided to contain the solid waste generated by the project. Full dusrpsters should be removed from the project site and the contents should be disposed of by The trash hauling contractor. Constructor debris and waste should be removed from the site biweekly or more frequently as neeied. Constrcction material vis to the public should be stored or stacked in an orderly manner. Stormwater i•urion should he prevented from contacting stored solid waste through the use of berns, dikes, or other temporory diversion structures or through the use of measures to elevate w:ste from site surfaces. Solid waste stcrage areas should be located at least 50 ft from drainage facilities and watercourses cnd should not be located in areas prone to flooding or ponding. inspect and verify that activity BMPs are in place prior to the commencement of associated act,vities ASile activities associated with the BMP are under way, inspect weekly to verily continued BMP implementation. inspect Bt1Ps subject to non--stormwater discharge daily while non-stormwater discharges occur i nspect construction waste area regularly. Arrange for regular waste collection. The following steps will help reduce stormwater pollution from concrete wastes: Discuss the concrete management techniques described in this BMP (such as hand of concrete waste and washout) with the ready-mix concrete supplier before any deliveries ore !:rcorporate requirements for concrete waste management into material supplier and Subcontractor agreements. Store dry and wet materials under cover, away from drainage areas. Avoid mixing excess amounts of fresh concrete. Perform washout of concrete trucks offsite or in designated areas only. Do not wash out concrete trucks into storm drains, open ditches, streets, or streams. Do not allow excess concrete to be dumped onsite, except in designated oreas. For onsite washout: Locate washout area at least 50 feet from storm drains, open ditches, or water bodies. Do not allow runoff from this area by constructing a temporary pit or bermed area large enough for liquid and solid waste. Wash out wastes into the temporary pit where the concrete can set, be broken up, and then disposed properly. Avoid creating runoff by draining water to a bermed or level area when washing concrete to remove fine particles and expose the aggregate. Do not wash sweepings from exposed aggregate concrete into the street or storm dram. Collect and return sweepings to aggregate base stockpile or dispose in the trash. D:2.AFF 0,fjLi lpE[7T:C) Description and Purpose Deatering operations are p ractices that manage the discharge of pollutants when non-stormwater and accumu precipitation must be removed from a work location so that construction work flOOy be accomplished SutabIe Applications These practices are implemented for discharges of nonstormwater from construction sites. Non-stormwaters include, but are not l imited to, groundwater, water from cofferdams, water diversions, and waters used during construction activities that must be rerroved from a work area. Practices identified in this section are a appropriate for imp when managing the removal of accumu precipitation(stormwater) from depressed ]recs at a construct site. Lirn tation s Site conditions will dictate design and use of dewatering operations. The controls discussed in this best management proctice (BMP) address sediment only. The controls detai in this BMP only allow for minimal settling time for sediment partic Use only when site conditions restrict the use of the other control methods. Dewatering operations will require, and rflLSt comply with, applicab local permits. Impl ementation Dewatering discharges must not cause erosion at the discharge point. A variety of methods can be used to treat water during deWatering operations. Several devices are presented below and provide options to achieve sediment removal. The size of particles present in the sediment and Permit or receiving water imitations on sediment are key considerations for selecting sediment treatment option(s); in some cases, the use of mu devces may be appropriate. Sediment Basin sediment basin is a temporary basin with a controlled release structure that is formed by excavation or construction of an embankment to detain sediment-laden runoff and allow sediment to settle out before discharging. Sediment basins are generally larger than Sediment Traps. /ir.:,o,c, .pt7•c'•7)"( Effective for the removal of gravel, sand, silt, some metals that settle out with the sediment, and trash. Excavation and construction of related facilities is required. Temporary sediment basins must be fenced if safety is a concern. Outlet protection is required to prevent erosion at the outfali location. Maintenance is required for safety fencing, vegetation, embankment, inlet nd outfall structures, as well as other features. Removal of sediment is required when the storage volume is educed by one-half. Sediment Trap A sediment trap is a temporary basin formed by excavation and/or construction of an earthen embankment across a waterway or low drainage area to detain sediment-laden runoff and allow sediment to settle out before discharging. Sediment traps are generally smaller than Sediment Basins. 0.' 2 .cr7 Effective for the removal of large and medium sized particles (sand and gravel) and some metals that settle out with the sediment. Excavation and construction of related facilities is required. Trap inlets should be located to maximize the travel distance to the trap outlet. Use rock or vegetation to protect the trap outlets against erosion. Maintenance is required for vegetation, embankment, inlet and outfall structures, as well as other features. Removal of sediment is required when the storage volume is reduced by one-third. Is this Evaluation followina a rainfall A gravity bag filter, also referred to as a dewatering bag, is a square or rectangular bag made of non-woven geotextile fabric that collects sand, silt, and fines. 3 50'1 7 .D.'/rJbb.

EVALUATION FOR CONSTRUCTION PROJECTS A trained individual shall perform a written evaluation of the project site. a. By the end of the next business day following each rainfall that exceeds 0.5" b. A minimum of one (1) time per week Gravity Bag Filter Water is pumped into one side of the bag and seeps through the bottom and sides of the bag. A secondary barrier, such as a rock filter bed or straw/hay bale barrier, IS placed beneath and beyond the edges of the bag to capture sediments that escape the bag. I nspection of the flow conditions, bag condition, bag capac and the secondary barrier is required. Replace the bag when it no longer filters sediment or passes w ater at a reasonable rate.The bag is disposed of offsite.
