Materials shall be stored in the designated material storage area. Spill prevention for vehicle and equipment fueling shall conform to the following practices: vehicle equipment fueling procedures andpractices are designed to prevent fuel spills and leaks, and reduce or eliminate contamination of stormwater. This can be accomplishedby using offsite facilities, fueling in designated areas only, enclosing or covering stored fuel, implementing spill controls, and trainingemployees and subcontractors in proper fueling procedures. Limitations: Onsite vehicle and equipment fueling should only be usedwhere it is impractical to send vehicles and equipment offsite for fueling. Sending vehicles and equipment offsite should be done inconjunction with a Stabilized Construction Entrance/Exit. Implementation: Use offsite fueling stations as much as possible. Discourage"topping-off" of fuel tanks. Absorbent spill cleanup materials and spill kits should be available in fueling areas and on fueling trucks, andshould be disposed of properly after use. Drip pans or absorbent pads should be used during vehicle and equipment fueling, unless thefueling is performed over an impermeable surface in a dedicated fueling area. Use absorbent materials on small spills. Do not hosedown or bury the spill. Remove the absorbent materials promptly and dispose of properly. Avoid mobile fueling of mobile constructionequipment around the site; rather, transport the equipment to designated fueling areas. Train employees and subcontractors in properfueling and cleanup procedures. Dedicated fueling areas should be protected from stormwater runon and runoff, and should be locatedat least 50 ft away from downstream drainage facilities and watercourses. Fueling must be performed on level-grade area. Protectfueling areas with berms and dikes to prevent runon, runoff, and to contain spills. Nozzles used in vehicle and equipment fueling shouldbe equipped with an automatic shutoff to control drips. Fueling operations should not be left unattended. Federal, state, and localrequirements should be observed for any stationary above ground storage tanks. Vehicles and equipment should be inspected each day of use for leaks. Leaks should be repaired immediately or problem vehiclesor equipment should be removed from the project site. Keep ample supplies of spill cleanup materials onsite. Immediately clean upspills and properly dispose of contaminated soils. Spill prevention for solid waste shall conform to the following practices: Solid waste management procedures and practices aredesigned to prevent or reduce the discharge of pollutants to stormwater from solid or construction waste by providing designated wastecollection areas and containers, arranging for regular disposal, and training employees and subcontractors. Solid waste generated fromtrees and shrubs removed during land clearing, demolition of existing structures, and building construction. Packaging materialsincluding wood, paper, and plastic. Scrap or surplus building materials including scrap metals, rubber, plastic, glass pieces and masonryproducts. Domestic wastes including food containers such as beverage cans, coffee cups, paper bags, plastic wrappers, and cigarettes.Construction wastes including brick, mortar, timber, steel and metal scraps, pipe and electrical cuttings, non-hazardous equipment parts,Styrofoam and other package construction materials. Select designated waste collection areas onsite. Inform trash-hauling contractorsthat you will accept only watertight dumpsters for onsite use. Inspect dumpsters 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 container to keep rain out or to prevent loss ofwastes when it is windy. Plan for additional containers and more frequent pickup during the demolition phase of construction. Collectsite trash daily, especially during rainy and windy conditions. Remove this solid waste promptly since erosion and sediment controldevices tend to collect litter. Make sure that toxic liquid wastes (sued oils, solvents and paints) and chemicals (acids, pesticides,additives, curing compounds) are not disposed of in dumpsters designed for construction debris. Do not hose out dumpsters on theconstruction site. Leave dumpster cleaning to the trash hauling contractor. Arrange for regular waste collection before containersoverflow. Clean up immediately if a container does spill. Make sure that construction waste is collected, removed, and disposed of onlyat authorized disposal areas. Solid waste storage areas should be located at least 50 ft from drainage facilities and watercourses andshould not be located in areas prone to flooding or ponding. Inspect construction waste area regularly. Arrange for regular wastecollection. Spill prevention for concrete washout shall conform to the following practices: Store dry and wet materials under cover, away fromdrainage 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 duped onsite,except in designated areas. Locate washout areas at least 50 ft from storm drains, open ditches, or water bodies. Do not allow runofffrom this area by constructing a temporary pit or bermed area large enough for liquid and solid waste. Wash out wastes into thetemporary pit where the concrete can set, be broken up, and then disposed properly. Avoid creating runoff by draining water to abermed or level area when washing concrete to remove fine particles and expose the aggregate. Do not wash sweepings from exposedaggregate concrete into the street or storm drain. Collect and return sweepings to aggregate base stockpile or dispose in the trash.The cleanup parameters shall conform to the following practices: The developer / homeowners association shall be continually keptinformed, maintain lists of qualified contractors and available Vac-trucks, tank pumpers and other equipment readily accessible forcleanup operations. In addition, a continually updated list of available absorbent materials and cleanup supplies should be kept on site.All maintenance personnel will be made aware of techniques for prevention of spills. They will be informed of the requirements andprocedures outlined in this plan. They will be kept abreast of current developments or new information on the prevention of spills and /or necessary alteration to this plan. When spills occur which could endanger human life and this become primary concern, the dischargeof the life saving protection function will be carried out by the local police and fire departments. Absorbent materials, which are used incleaning up spilled materials, will be disposed of in a manner subject to the approval of the Indiana Department of EnvironmentalManagement. Flushing of spilled material with water will not be permitted unless so authorized by the Indiana Department ofEnvironmental Management.Potential pollutants sources relative to a construction site may include, but are not limited tomaterial and fuel storage areas, fueling locations, exposed soils and leakingvehicle/equipment. Potential pollutants that may appear at the site due to constructionactivities include, but are not limited to diesel fuel, gasoline, concrete and concrete washout,solid waste, sediment, paint and solvents, equipment repair products, anti-freeze andfertilizer. No Non-stormwater discharge sources were identified for this project site.In order to contain potential pollutants several construction stage measures will beimplemented. This includes a stable construction entrance, paved area inlet protection onand adjacent to the site, perimeter silt fencing, and temporary stabilization as necessary.A stone construction entrance will be located at the north side of the site. See Sheet C104for plan location and Sheet C105 for details and specifications.Seeding will be used as temporary surface stabilization measures as well as Permanentsurface stabilization measures. The location of each surface stabilization measure are onsheet C104. The details and specifications for each stated measure are on sheet C105.install temporary seeding after a specific stage of construction has been completed(temporary or final) where areas will be idle of construction activities for a period of 15 daysor more.Temporary seeding will be used as erosion control measures for concentrated flows.

Potential pollutant sources that may appear at thesite due to proposed land use activities, but are not limited to vehicles, exposed soil and trash. Potentialpollutants include, but are not limited to oil, grease, antifreeze, brake fluid, brake dust, rubber fragments,gasoline, diesel fuel and other hydrocarbons, metals from vehicular and other sources, grit (sediment) fromwearing of the road surface and falling or washing off of vehicles, trash (including bacteria and other biologicalagents contained in the trash) from littering and other types of improper disposal or storage, and elevatedreceiving water temperatures from stormwater run-off contact with impervious surfaces.The use of an existing mechanical water quality structure (Aqua-Swirl AS-4) and an isolator row in an existingunderground detention facility will provide the stormwater quality requirements. The location of stormwaterquality measures are on sheet C104. The stormwater quality specifications are provided on sheets C802 andADS 1-5.All details of the proposed stormwater infrastructure found on C103, C802 and ADS 1-5.The existing underground detention facility will be increased with two (2) chamber rows. Undergroundroofdrains will be around the building addition to collect the new roof drainage and direct it to an existing on-sitestorm sewer. After final seeding and the completion of all construction activities, it is the responsibility of theContractor/Responsible entity to remove any trash or sedimentation from the storm inlets. See Maintenanceguidelines for post-construction stormwater measures below.An Operations & Maintenance Manual has been prepared for this site. The Owner is responsible forimplementing and reporting the post-construction water quality measures as outlined in the O&M Manual.Any debris in the parking areas should be picked up and placed in the trash receptacle. The parking area shallbe kept clean and be swept every 3 months.Storm Sewer SystemInspect the system every six months. Evaluate the condition of the system and confirm no riprap failures, stormdrains are in good condition with no evidence of non-stormwater discharges or excessive sedimentation, inletand outlet structures are in good repair with no cracks or excessive sediments in the structures, castings wellseated and orifice openings free of obstructions.

Spill prevention for vehicle and equipment maintenance shall conform to the following practices: Prevent orreduce the contamination of stormwater resulting from vehicle and equipment maintenance by running a "dryand clean site". The best option would be to perform maintenance activities at an offsite facility. If this optionis not available then work should be performed in designated areas only, while providing cover for materialsstored outside, checking for leaks and spills, and containing and cleaning up spills immediately. Theseprocedures are suitable on all construction projects where an onsite yard area is necessary for storage andmaintenance of heavy equipment and vehicles. Onsite vehicle and equipment maintenance should only beused where it is impractical to send vehicles and equipment offsite for maintenance and repair. Sendingvehicles / equipment offsite should by done in conjunction with a stabilized construction entrance / exit. Outdoor vehicle or equipment maintenance is a potentially significant source of stormwater pollution. Activities thatcan contaminate stormwater include engine repair and service, changing or replacement of fluids, and outdoorequipment storage and parking (engine fluid leaks). If maintenance must occur onsite, use designated areas,located away from drainage courses. Dedicated maintenance areas should be protected from stormwaterrunon and runoff, and should be located at least 50 ft from downstream drainage facilities and water courses.Drip pans or absorbent pads should be used during vehicle and equipment maintenance work that involvesfluids, unless the maintenance work is performed over and impermeable surface in a dedicated maintenancearea. Place a stockpile of spill cleanup materials where it will be readily accessible. All fueling trucks andfueling areas are required to have spill kits and/or use other spill protection devices. Use absorbent materialson small spills. Remove the absorbent materials promptly and dispose of properly. Inspect onsite vehicles andequipment daily at startup for leaks, and repair immediately. Deep vehicles and equipment clean; do not allowexcessive buildup 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 secondarycontainment and covers for these materials if stored onsite. Train employees and subcontractors in proper maintenance and spill cleanup procedures. Drip pans or plasticsheeting should by placed under all vehicles and equipment placed on docks, barges, other structures overwater bodies when the vehicle or equipment is planned to be idle for more than 1 hour. Properly dispose ofused oils, fluids, lubricants, and spill cleanup materials. Properly dispose of or recycle used batteries. Do notplace used oil in a dumpster or pour into a storm drain or water course. Properly dispose of used oils, fluids,lubricants, and spill cleanup materials. Don not bury tires. Repair leaks of fluids and oil immediately. Spill prevention for fertilizers shall conform to the following practices: Fertilizer's used will be applied only inthe minimum amounts recommended by the manufacturer. Once applied, fertilizer will be worked into the soil tolimit exposure to storm water. The contents of any partially used bags of fertilizer will be transferred to asealable plastic bin to avoid spills. Spill prevention for paint and solvents shall conform to the following practices: All containers will be tightlysealed and stored when not required for use. EXCESS PAINT WILL NOT BE DISCHARGED TO THE STORMSEWER SYSTEM but will be properly disposed of according to manufacturers' instructions or State or localregulations. Spill prevention and cleanup shall conform to IDEM form 327 IAC 2-6 and the Indianapolis Fire Department(317-327-3811) and IDEM Spill Response Center (888-233-7745) shall be contacted in the case of a materialspill occurring.1.during vegetative establishment, inspect after storm events for any erosion below the blanket.2.if any area shows erosion, pull back that portion of the blanket covering it, add soil, re-seed the area, and re-lay and staple the blanket.3.after vegetative establishment, check the treated area periodically. temporary gravel construction entrance maintenance requirements1.inspect entrance pad and sediment disposal area weekly and after storm events or heavy use.2.reshape pad as needed for drainage and runoff control.3.topdress with clean stone as needed.4.immediately remove mud and sediment tracked or washed onto public roads by brushing or sweeping. flushing should only be used if thewater is conveyed into a sediment trap or basin.5.repair any broken road pavement immediately.C103 provides the stormwater discharge of the site into Carmel Creek.C101 identifies all proposed site activities with particular detail to the stormwaterinfrastructure provided on C103.N/AAll Equipment staging and refueling areas will be located on-site.
