R1 Description of potential pollutants sources associated with the construction activities: Silt and sediment from exposed soils, leaves, mulch, vehicular sources such as leaking fuel or oil, broke fluid, brake dust, trash, debris, biological agents found in trash, fertilizers, herbicides, pesticides, acid rain, lime dust and concrete washout. B2 Sequencing of stormwater quality implementation relative to land disturbance activities: Q1 This plan has been created in an effort to eliminate sediment from leaving the project site during construction protecting the adjoining properties and the receiving waters. As mentioned previously, the existing site currently conveys runoff to a series of onsite inlets. Runoff is then conveyed to an existing storm pipe system that leads to a detention pond that was part of a master plan design for Meridian Technology Center. PRECONSTRUCTION ACTIVITIES: 1. Call the Indiana Underground Plant Protection systems, Inc. ( "Holey Moley") at 1- 800 - 382 -5544 to check the location of any existing utilities. They should be notified two working days before construction takes place. 2. Notify the City of Carmel Engineering Department at least 48 hours prior to any land disturbance. 3. Evaluate the site for vegetative areas to be saved. See Sheet C104. 4. An orange construction fence shall be constructed along the perimeter of the dripline of the tree preservation areas prior to any earth moving. 5. A silt fence shall be installed at the edges of the project site where there is potential for any stormwater runoff. Potential areas are identified based on existing topography along the perimeters of the site. 6. Evaluate, mark and protect important trees and associated root zones. Evaluate existing vegetation suitable for use as filter strips along the project boundaries. 7. Maintain a 5' minimum grass filter strip along the north and west boundaries of the project site. 8. A construction entrance shall be placed per the plan location. 9. Install protective devices along existing storm sewer inlets per locations shown on the Stormwater Pollution Prevention Plan Sheet C104. 10. Establish construction staging area for equipment and vehicles as for from detention ponds and swales as possible. 11. Establish onsite location for owner /operator /contractor placement of approved plans and Rule 5 N01 and Rule 5 inspection documentation. CONSTRUCTION ACTIVITIES: 1. Once erosion and sediment control measures are in place, begin land clearing followed immediately by rough grading. Do not leave large areas unprotected for more than 15 days. Rule 5 requires that all disturbed areas that potentially will be idle for 15 days or more will be stabilized (seeded, mulched, etc..) immediately. 2. Strip topsoil and temporarily stockpile in location provided on the Stormwater Pollution Prevention Plan Sheet C104. 3 Perform rough grading. 4. After completion of rough grading, final grade. 5. After final grading is complete, seed and mulch or sod landscape areas. 6. Upon completion of rough grading, install sanitary and storm sewers. As storm sewers are constructed, install inlet protection measures. 7. Upon completion of sewer installation and inlet protection, proceed with building construction. 8. Upon building construction, proceed with pavement construction. 9. Liming of pavement subgrade should be done prior to the installation of storm sewers to prevent the transmission of lime dust to ponds or receiving waters. 10. Once pavement and curbs are in place, install curb inlet sediment barriers. 11. Once inlet protection is in place, final grade all areas and spread topsoil. 12. Remove all temporary erosion and sediment control practices. 13. Submit Rule 5 NOT to the City of Carmel Engineering Department. K Stable construction entrance location(s) and specifications.

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, point, 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. Navigable Waters: Means all waters of the United States that are connected with a navigable 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 navigable stream]. Plan Review and Amendements: 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 effects the site's potential for the discharge of regulated material AND groundwater contamination. The facility does have city sanitary sewer and city water. Prediction of Potential Spills: 1. Nearest Navigable Water: White River - Carmel Creek - WR Fertig Regulated Drain 2, Drainage System: The proposed drainage system will follow the existing drainag: patterns and existing storm sewer system. Detention will be provided offsite by the regional detention ponds as part of Meridian Technology Park. 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 to cleaning agents, chemicals, paint, herbicides and pesticides. 4. Groundwater Contamination: The facility maintains NO above ground or under ground storage tanks at this site. Therefore, it is felt that there is little or no possibility of post construction groundwater contaimination. Alert Procedures for Spills: 1. Any personnel observing a spill will immediately instigate the following procedure: a.) Dialing "0" from any telephone. b.) Notify the appropriate emergency personnel. 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.) Notify the Indiana Department of Environmental Management, Office of Emergency Response by calling the appropriate telephone number 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 sp''I - 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 local Fire Department Phone: 9 -1 -1 d.) Notify the local Police Department Phone 9 -1 -1 e.) Notify waste recovery contractor, maintenance personnel or other contractual personnel as necessary for cleanup. f.) Coordinate and monitor cleanup until the situation has been v stabilized and all spills have bee n 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 r outlined in this Ian. They be will be informed of the requirements and procedures out e p y kept abreast of current developments or new information on the prevention of spills and / or necessary alterations 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 mateials, 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. B14 Monitoring and maintenance guidelines for pollution prevention measures: Silt Fence Maintenance Requirements 1. 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 it's lowest point or is causing the 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 it. Erosion Control Blanket (surfuce Applied) Maintenance Requirements 1. During vegetative establishment, inspect after each storm event for any erosion below the blanket. 2. If any oreo(s) shows erosion, pull back that portion of the blanket covering it, re -seed the area and relay and staple the blanket. 3. After vegetative establishment check the treated area periodically. Temporary Gravel Construction Entrance Maintenance Requirements 1. Inspect entrance pad and sediment disposal area weekly and after storm events or heavy use. 2. Reshape as needed for drainage and runoff control. 3. Topdress 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 or basin. 1. Remove all sediment and debris from vicinity of the unit after each storm event. 2. After storm event and at regular intervals, look into the Dandy Sack . If the containment area is more than )� full of sediment, the unit must be emptied. 3. To empty unit, simply lift the unit out of the inlet using the lifting straps and remove the grate. 4. If using optional oil absorbents, replace absorbent pillow when near saturation. A A B15 Erosion & sediment control specifications for individual building lots: Not applicable.

The best option would be to perform maintenance activities at or offs to focility. If this option is not available then work should be performed ;r. designated arecs only, while providing cover for materials stored outside, checking for leaks and spills, and containing and cleaning up spills immediately. Suitable Applicatiors These procedures ore 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 mairtenance should only be used where it is impractical to send vehicles and equipment offsite fo, maintenance and repair. Sending vehicles /equipment offsite should be done in conjunction with a Stabilized Construction Entrance /Exit. Outdoor vehicle or equipment maintenance is a potentially significant source of stormwater pollution. Activities that can contom'note stermwcter include engine repair and service, changing or replacement of fluids, and outdoor equipment storage and parking (engine fluid leaks). Implementation If maintenance must occur onsite, use designated areas, located away from drainage courses. Dedicated maintenance areas should be protected from stormwater runon and runoff, and should be located at lean 50 it from downstream drainage facilities and watercourses. Drip pans or absorbent pods sno.ild be used during vehicle and equipment maintenance work that involves fluids, unless the maintenance work is performed over an impermeable surface 'n a dedicatee maintenance area. Rcce c stackpiie of spill c•ean.ip matea s where it will be readily accessible. All fueling trucks and fue Ing 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 property. nspect onsite vehicles a nd e jp ment .ad y at startup for leaks, and repair immediately. Keep vehicles and equipment clean: ae rot allow excessive build -up of oil and grease. Segregate and recycle wastes, s.ich os greases, used oil or oil filters, antifreeze, cleaning solutions, automotive batteries, hydroul'c end transmission fluids. Provide secondary containment and covers for these rnate�ais if stored onsite. Train empoyees and subcontractors in proper maintenance and spill cleanup procedures. Drip pans or plastic sheeting should be placed under all vehicles and equipment placed on docks, barges, or other structures over water bodies when the vehicle or equipment is planned to be idle for more than 1 hour. Property dispose of used oils, fluids, lubricants, and spill cleanup materials. Do not place used oil in a dumpster or pour into a storm drain or watercourse. Property dispose of or recycle used potteries. Do not bury used tires. Repair leaks of fluids and ci! immediately. Listed below is fLr`lFer information ` ,;u must perform vehicle or equipment maintenance ons'te. nspection and Maintenance Inspect and verify that BMPs are r p cce prior to the commencement of associated activities. While activities cssociated 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 leok proof condition. Vehicles and equipment should be inspected on each day of use. Leaks should be repaired immediately 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. VEHICLE AND EQUIPMENT FUELING Description and Purpose Vehicle equipment fueling proceaures and practices are designed to prevent fuel spills and leeks, 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, one training employees and subcontractors in proper fueling procedures. Limitations vehicle n e ment fueling Onsite a d ui e p g should only be used where it is impractical to send vehicles and equipment offsite for fueling. Sending vehicles and equipment offsite should 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 spil 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 or small spills. Do not hose down or bury the spill. Remove the adsorbent mater;ds promptly and dispose of properly. Avoid mobile fue ing of mobile construction equipment around the site; rather, transport the equipment to designated fueling areas. Tro:n employees and subcortractors in proper fueling and cleanup procedures. Dedicated fueling areas should oe protected from stormwater runon and runoff, and should be located at least 50 ft away f-em downstream drainage facilities and watercourses. Fueling must be performed on level - grcde 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 shut 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 problem vehicles or equipment should be removed from the project site. Keep ample supplies of spill cleanup materials onsite. Immediately clean up spills and properly dispose of contaminated soil and cleanup m oteriol s. SOLI D WASTE MANAGEMENT Descriotion 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 corto.ners, 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 matenais including scrap metals, rubber, plastic, glass pieces and masonry products 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, nonhazardous equipment parts, styrofoom and other materials send transport and package construction materials Implementation The 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 to keep 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 soiia wcste promptly since erosion and sediment control devices tend to collect litter. Make sure that icxic 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 hauling contractor. 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 disposal areas. Collection Storage and Disposal Littering on the project site should be prohibited. To prevent clogging of the storm drainage system, litter and debris removal from drainage grates, trash racks, and ditch lines should be a priority. Trash receptacles should be provided in the contractor's 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 placed in watertight dumpsters at least weekly, regardless of whether the litter was generated by the 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 the project. Full dumpsters should be removed from the project site and the contents should be disposed of by the trash 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 runon 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 site surfaces. Solid waste storage areas should be located at least 50 ft from drainage facilities and watercourses and should not be located in areas prone to flooding or pending. Inspection and Maintenance Inspect 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. Inspect BMPs subject to non - stormwater discharge daily while non - stormwater discharges occur Inspect construction waste area regularly. Arrange for regular waste collection. CONCRETE WASHOUT The following steps will help reduce stormwater pollution from concrete wastes: Discuss the cor rete management techniques described in this BMP (such as handling of concrete waste and washout) with the ready -mix concrete supplier before any deliveries are made. Incorporate requirements for concrete waste management into material supplier and subcontractor agreements. Store dry and Net materials under cover, away from droinage 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 areas. 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 drain. Collect and return sweepings to aggregate base stockpile or dispose in the trash. DEWATERING AND PUMPING OPERATIONS Descriptior and Purpose Dewatering operations are practices that manage the discharge of pollutants when non - stormwater and accumulated precipitation must be removed from a work location so that construction work may be accomplished. Suitable Applications These practices are implemented for discharges of nonstormwater from construction sites. Non - stormwaters include, but are not limited to, groundwater, water from cofferdams, water diversions, and waters used during construction activities that must be removed from a work area. Practices identified in this section are also appropriate for implementation when managing the removal of accumulated precipitation(stormwater) from depressed areas at a cons:rjction site. Limitations Site conditions will dictate design and use of dewatering operations. The controls discussed in this best management practice (BMP) address sediment only. The controls detailed in this BMP only allow for minimal settling time for sediment particles. Use only when site conditions restrict the use of the other control methods. Dewatering operations will require, and must comply with, applicable local permits. Implemen,otion 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 limitations on sediment are key considerations for selecting sediment treatment option(s); in some cases, the use of multiple devices may be appropriate. Sediment Basin Description: A 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. Appropriate Applications: Effective for the removal of gravel, sand, silt, some metals that settle out with the sediment, and trash. Implementation: 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 outfall location. Maintenance: Maintenance is required for safety fencing, vegetation, embankment, inlet and outfall structures, as well as other features. Removal of sediment is required when the storage volume is reduced by one -half. Sediment Trap Description: 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. Appropriate Applications: Effective for the removal of large and medium sized particles (sand and gravel) and some metals that settle out with the sediment. I mplementation: 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: Maintenance is required for vecetation, embankment, Inlet and outfall structures, as well as other features. Removal of sediment is required when the storage volume is reduced by one- third. Gravity Bag Filter Description: A gravity bag filter, also r ?ferred to as a dewatering bag, is a square or rectangular bag made of non -woven geotextile fabric that collects sand, silt, and fines. Appropriate Applications: Effective for the -emoval of sediments (gravel, sand, and kilt). Some metals are removed with the sediment. Implementation: 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.
