CARMEL CHURCH 14598 OAK RIDGE RD, CARMEL, IN 4603219038CrA Crosby silt loam, 0 to 3 percent slopesThis is a somewhat poorly drained soil with a seasonal high water table at 0.5 to 2.0 ft. This soil is located onrises on till plains; slopes are 0 to 3 percent. The native vegetation is hardwood forest. The surface layer is siltloam and has moderately low to moderate organic matter content (1.0 to 3.0 percent). Permeability is very slow(<0.06 in/hr) in the most restrictive layer above 60 inches. Available water capacity is moderate (6.2 inches in theupper 60 inches). The pH of the surface layer in non-limed areas is 5.1 to 6.5. Droughtiness and wetness aremanagement concerns for crops production. This soil responds well to tile drainage; it is designated potentiallyhighly erodible (class 2) in the Highly Erodible Land (HEL) classification system.Br Brookston silty clay loam, 0 to 2 percent slopesThe Brookston component makes up 100 percent of the map unit. Slopes are 0 to 2 percent. This component ison depressions on till plains. The parent material consists of loess over loamy till. Depth to a root restrictive layeris greater than 90 inches. The natural drainage class is poorly drained. Water movement in the most restrictivelayer is moderately high. Available water to a depth of 60 inches is high. Shrink-swell potential is moderate. Thissoil is not flooded. It is frequently ponded. A seasonal zone of water saturation is at 6 inches during January,February, March, April, May, December. Organic matter content in the surface horizon is about 4 percent.Nonirrigated land capability classification is 2w. This soil meets hydric criteria.SOILS MAPBMP - Stormwater Quality Treatment Unit (XCELERATOR XC-6 & XC-7)Basic OperationThe Storm water Quality Treatment Unit ( SQTU ) is a hydrodynamic separator designed to enhance gravitational separation offloating and settling materials from storm water flows. Storm water flows enter the unit tangentially to the grit chamber, whichpromotes a gentle swirling motion. As polluted water circles within the grit chamber, pollutants migrate toward the center of theunit where velocities are the lowest. The majority of settleable solids are left behind as storm water exits the grit chamberthrough two apertures on the perimeter of the chamber. Next, buoyant debris and oil and grease are separated from waterflowing under the baffle wall due to their relatively low specific gravity. As storm water exits the System through the flowcontrol wall and ultimately through the outlet pipe, it is relatively free of floating and settling pollutants.Over time a conical pile tends to accumulate in the center of the unit containing sediment and associated metals, nutrients,hydrocarbons and other pollutants. Floating debris and oil and grease form a floating layer trapped in front of the baffle wall.Accumulation of these pollutants can easily be assessed through access manholes over each chamber. Maintenance istypically performed through the manhole over the grit chamber.Inspection of SQTUSQTU should be inspected at regular intervals and maintained when necessary to ensure optimum performance. The rate atwhich the System collects pollutants will depend more heavily on site activities than the size of the unit, e.g., unstable soils orheavy winter sanding will cause the grit chamber to fill more quickly but regular sweeping will slow accumulation.Inspection is the key to effective maintenance and is easily performed. Quarterly inspections of the accumulated sediment.Pollutant deposition and transport may vary from year to year and quarterly inspections will help insure that Systems arecleaned out at the appropriate time. Inspections should be performed more often in the winter months in climates wheresanding operations may lead to rapid accumulations, or in equipment wash down areas. It is very useful to keep a record ofeach inspection.The SQTU system should be cleaned when inspection reveals that the sediment depth has accumulated to the determinedelevation or depth. This determination can be made by taking 2 measurements with a stadia rod or similar measuring device.Cleaning of SQTU StructuresMaintaining the SQTU is easiest when there is no flow entering the Systems. For this reason, it is a good idea to schedule theclean out during dry weather. Clean out of the SQTU with a vacuum truck is generally the most effective and convenientmethod of excavating pollutants from the System. If such a truck is not available, a "clamshell" grab may be used, but it isdifficult to remove all accumulated pollutants with such devices.Oil or gasoline spills should be cleaned out immediately. Motor oil and other hydrocarbons that accumulate on a more routinebasis should be removed when an appreciable layer has been captured. To remove these pollutants, it may be preferable touse adsorbent pads since they are usually cheaper to dispose of than the oil water emulsion that may be created byvacuuming the oily layer. Trash can be netted out if you wish to separate it from the other pollutants.Accumulated sediment is typically evacuated through the manhole over the grit chamber. Simply remove the cover and insertthe vacuum hose into the grit chamber. As water is evacuated, the water level outside of the grit chamber will drop to thesame level as the crest of the lower aperture of the grit chamber. It will not drop below this level due to the fact that the bottomand sides of the grit chamber are sealed to the tank floor and walls. This "Water Lock" feature prevents water from migratinginto the grit chamber, exposing the bottom of the baffle wall. Floating pollutants will decant into the grit chamber as the waterlevel there is drawn down. This allows most floating material to be withdrawn from the same access point above the gritchamber.If maintenance is not performed as recommended, sediment may accumulate outside the grit chamber. If this is the case, itmay be necessary to pump out all chambers. It is a good idea to check for accumulation in all chambers during eachmaintenance event to prevent sediment build up there.Manhole covers should be securely seated following cleaning activities, to ensure that surface runoff does not leak into the unitfrom above.After a storm event, treated runoff is decanted out of the SQTU at a controlled rate, restoring the water level to a lowdry-weather volume. This reveals a conical pile of accumulated sediment in the center of the grit chamber. Besides facilitatinginspection and cleaning through the unobstructed access, the low water level significantly reduces maintenance costs bydecreasing pump-out volume.Note: As the generator, the landowner is ultimately responsible for the proper disposal of materialremoved from water quality treatment structures.Quarterly inspections of the SQTU shall include observation of the accumulated sediment. Pollutant deposition andtransport may vary from year to year and quarterly inspections will help insure that the systems are cleaned out at theappropriate time. Inspections should be performed more often in the winter months in climates where sanding operationsmay lead to rapid accumulations, or in equipment wash down areas.CONSTRUCTION SITE SWPPP CONTINUED8. Continued:L. Monitoring and Maintenance Guidelines Continued.Monitoring and maintenance guidelines for each proposed storm water quality measure:Temporary gravel construction entrance maintenance requirements1.Inspect entrance pad and sediment disposal area weekly and after storm events or heavy use.2.Reshape as needed for drainage and runoff control. Maintain 150' driveway length.3.Top dress with clean stone as needed.4.Immediately remove mud and sediment tracked or washed onto streets by brushing or sweeping. Flushing should only be used if the water is conveyed into a sediment trap of basin.5.Repair any broken road pavement immediately.Silt fence maintenance requirements1.Inspect the silt fence periodically and after each storm event.2.If fence fabric tears, starts to decompose or in any way becomes ineffective, replace the affected portion immediately.3.Remove deposited sediment when it reaches half the height of the fence at its lowest point or is causing fabric to bulge.4.Take care to avoid undermining the fence during cleanout.5.After the contributing drainage area has been stabilized, remove the fence and sediment deposits, bring the disturbed area to grade and stabilize.Inlet Protection, and Drop Inlet barrier maintenance requirements.1.Inspect after each storm event and repair if necessary.2.Remove sediment, without flushing, when it reaches half the height of barrier.3.Deposit removed sediment where it will not enter storm sewer drains.4.Replace or repair if torn or damaged in other ways.5.5.When contributing drainage area has been stabilized, remove and properly disposeof construction material and sediment, finish grade the disturbed area and stabilize..Erosion control blanket (surface applied) maintenance requirements1.During vegetative establishment, inspect after each storm event for any erosion belowthe blanket.2.If any area(s) shows erosion, pull back that portion of the blanket covering it, reseed the area and relay and staple the blanket.3.After vegetative establishment check the treated area periodically.Topsoil (Salvage and Utilization):1.Inspect newly topsoiled areas frequently until vegetation is established2.Repair eroded or damaged areas and re-vegetate.All erosion and sediment control measures must be properly maintained throughoutconstruction. Temporary and permanent seeding should be watered as needed untilestablished. See Plan Sheet C403.ImplementationThe following steps will help keep a clean site and reduce stormwater pollution:Select designated waste collection areas onsite.Inform trash-hauling contractors that 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 tokeep rain out or to prevent loss of wastes when it is windy.Plan for 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 litter.Make sure that toxic liquid wastes (used oils, solvents, and paints) and chemicals (acids, pesticides,additives, curing compounds) are not disposed of in dumpsters designated for construction debris.Do not hose out dumpsters on the construction site. Leave dumpster cleaning to the trash haulingcontractor.Arrange for regular 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 disposalareas.Collection, Storage, and DisposalLittering on the project site should be prohibited.To prevent clogging of the storm drainage system, litter and debris removal from drainage grates, trashracks, and ditch lines should be a priority.Trash receptacles should be provided in the contractor's yard, field trailer areas, and at locations whereworkers congregate for lunch and break periods.Litter from work areas within the construction limits of the project site should be collected and placed inwatertight dumpsters at least weekly, regardless of whether the litter was generated 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.Dumpsters of sufficient size and number should be provided to contain the solid waste generated by theproject.Full dumpsters should be removed from the project site and the contents should be disposed of by thetrash hauling contractor.Construction debris and waste should be removed from the site biweekly or more frequently as needed.Construction material visible to the public should be stored or stacked in an orderly manner.Stormwater runoff should be prevented from contacting stored solid waste through the use of berms,dikes, or other temporary diversion structures or through the use of measures to elevate waste from sitesurfaces.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.Inspection and MaintenanceInspect and verify that activity-based BMPs are in place prior to the commencement of associatedactivities. While activities associated with the BMP are under way, inspect weekly to verify continuedBMP implementation.Inspect BMPs subject to non-stormwater discharge daily while non-stormwater discharges occurInspect construction waste area regularly.Arrange for regular waste collection.VEHICLE AND EQUIPMENT FUELINGDescription and PurposeVehicle equipment fueling procedures and practices are designed to prevent fuel spills andleaks, and reduce or eliminate contamination of stormwater. This can be accomplished by usingoffsite facilities, fueling in designated areas only, enclosing or covering stored fuel,implementing spill controls, and training employees and subcontractors in proper fuelingprocedures.LimitationsOnsite vehicle and equipment fueling should only be used where it is impractical to sendvehicles and equipment offsite for fueling. Sending vehicles and equipment offsite should bedone in conjunction with a Stabilized Construction Entrance/ Exit.ImplementationUse offsite fueling stations as much as possible. These businesses are better equipped tohandle fuel and spills properly. Performing this work offsite can also be economical byeliminating 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 onfueling trucks, and should 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 hose down or bury the spill. Remove theadsorbent materials promptly and dispose of properly.Avoid mobile fueling of mobile construction equipment around the site; rather, transport theequipment 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 belocated at least 50 ft away from downstream drainage facilities and watercourses. Fueling mustbe 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 tocontrol drips. Fueling operations should not be left unattended.Federal, state, and local requirements should be observed for any stationary above groundstorage tanks.Inspection and MaintenanceVehicles and equipment should be inspected each day of use for leaks. Leaks should berepaired immediately or problem vehicles or equipment should be removed from the projectsite.Keep ample supplies of spill cleanup materials onsite.Immediately clean up spills and properly dispose of contaminated soil and cleanup materials.SOLID WASTE MANAGEMENTDescription and PurposeSolid waste management procedures and practices are designed to prevent or reduce thedischarge of pollutants to stormwater from solid or construction waste by providing designatedwaste collection areas and containers, arranging for regular disposal, and training employeesand subcontractors.Suitable ApplicationsThis 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 ofexisting structures (rubble), and building constructionPackaging materials including wood, paper, and plasticScrap or surplus building materials including scrap metals, rubber, plastic, glass pieces andmasonry productsDomestic wastes including food containers such as beverage cans, coffee cups, paper bags,plastic wrappers, and cigarettesConstruction wastes including brick, mortar, timber, steel and metal scraps, pipe and electricalcuttings, nonhazardous equipment parts, styrofoam and other materials send transport andpackage construction materialsSWPPP FOR POST CONSTRUCTION - CITY OF CARMEL1.Post Construction SWPP:A.Potential Land Use Pollutants: Description of pollutants and their sources associated with theproposed land use include Silt and sediment from expose soils, leaves, mulch, vehicular sourcessuch as leaking fuel or oil, brake fluid, brake dust, grease, antifreeze, metals, rubber fragments,road grit, salts and sands, construction trash and debris, fertilizers, household items including butnot limited to cleaning agents, chemicals, paint, miscellaneous home improvement materials, toys, clothing and animal waste, elevated storm runoff temperatures, acid rains, pesticides and pathogens.B.Location, Dimensions, specifications and construction Details of Storm water Quality Measures.The hydronamic filters are located upstream of the detention basin.

Material Handling and Spill Prevention Material handling and spill prevention plan: Purpose: The intention of this Spill Prevention, Control and Countermeasures (PCC) is to establish the procedures and equipment required to prevent the discharge of oil and hazardous substances in quantities that violate applicable water quality standards, cause a sheen upon or discoloration of the surface of Receiving water or adjoining shorelines, or cause sludge or emulsion to be deposited beneath the surface of the water or adjoining shorelines. The plan also establishes the activities required to mitigate such discharges (i.e. countermeasures) should they occur. Definitions: Pollutant: Means pollutant of any kind or in any form, including but not limited to sediment, paint, cleaning agents, concrete washout, pesticides, nutrients, trash, hydraulic fluids, fuel, oil, petroleum, fuel oil, sludge, oil refuse, and oil mixed with wastes other than dredged soil. Discharge: Includes, but is not limited to, any spilling, leaking, pumping, pouring, emitting, emptying or dumping.Receiving Navigable Waters: Means all waters of the United States that are connected witha Receiving stream, lake, or sea. [Note: this definition is usually interpreted to mean any wastewater even normally dry wash or storm sewer) that eventually drains into a Receiving stream. Plan Review Amendments:This plan shall be reviewed and/or amended, if necessary, whenever there is a change in the design of the site, construction, operation, or maintenance which materially affects the site's potential for the discharge of regulated material.Prediction of Potential Spills:1. Nearest Receiving Water: Cool Creek.2. Drainage System: In the pre-developed condition, storm runoff flows offsite to theeast, south, southwest and north. The runoff is routed via storm sewers to Cool Creek. In post construction conditions, most onsite runoff with be routed to an underground detention basin. The detention basin will drain via storm sewer to CoolCreek.3.Possible spill sources (during and post-construction): Vehicular sources such as leaking fuel or oil, brake fluid, grease, antifreeze; construction trash and debris, biological agents found in trash and debris, fertilizers,household items including but not limited cleaning agents, chemicals, paint,herbicides and pesticides.4.Groundwater contamination: The facility maintains NO above ground oil & separatoror underground storage tanks at this site. Therefore, it is felt that there is little or no possibility of post-construction groundwatercontamination. The facility does have city sanitary sewer and city water.Alert Procedures for Spills: 1. Any personnel observing a spill will immediately initiate the following procedure: a. Notify the designated emergency coordinator for the project. 2. The Emergency Coordinator will then take the following actions: a. Barricade the area allowing no vehicles to enter or leave the spill zone. b.

Office 317-233-7745 Toll Free 800-233-7745 Also the National Response Center at 800-424-8802 and provide the following information: - Time of observation of the spill - Location of the spill - Identity of material spilled - Probable source of the spill - Probable time of the spill - Volume of the spill and duration - Present and anticipated movement of the spill - Weather conditions - Personnel at the scene - Action initiated by personnel c. Notify the Carmel Fire Department : Phone 911 d. Notify the Carmel Police Department: Phone 911 e. Notify waste recovery contractor, maintenance personnel or other contractual personnel as necessary for clean up f. Coordinate and monitor clean up until the situation has been stabilized and all spills have been eliminated. g. Cooperate with the IDEM-OER on procedures and reports involved with the event.Cleanup Parameters: 1. The developer 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 available absorbent materials and clean up supplies should be kept on site. 2. All maintenance personnel will be made aware of techniques for prevention of spills. They will be kept abreast of current development or new information on the prevention of spills and/or necessary alteration to this plan. 3. 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. 4. Absorbent materials, which are used in cleaning up spilled materials, will be disposed of in a manner subject to the approval of the Indiana Department of Environmental Management. 5. Flushing of spilled material with water will not be permitted unless so authorized by the Indiana Department of Environmental Management.. 9.General Construction Sequencing:A.

The runoff is routed via stormsewers to Cool Creek. In post construction conditions, the new additions & a portion of the existingchurch will be treated by a BMP prior to discharging into the existing storm system.5.Identification of potential discharges to groundwater: Excavation pits can be potential sources ofdischarge into groundwater. There is a potential for discharges into groundwater from sedimentresulting from exposed soils, leaves, mulch, and vehicular sources if a significant rain event occurswhile excavations are open.6.Soils Map: The grading generally slopes away from the center of the site. To accommodate thisslope and prevent post construction pollutants from impervious areas from reaching the creek,impervious areas will drain to post construction storm water quality structures and elements.7.Potential Construction Pollutants: Silt and sediment from exposed soils, leaves, mulch, vehicularsources such as leaking fuel or oil, brake fluid, brake dust, trash, debris, biological agents found intrash, fertilizers, herbicides, pesticides, acid rain, lime dust and concrete washout.8.
