B2 Sequencing of stormwater quality implementation relative to land disturbance activities: This plan has been created in an effort to eliminate sediment from leaving the Village of WestClay Section 15001 project during construction protecting the adjoining properties and Elliot Creek. The majority of the existing watershed sheet drains to concentrated flow. The concentrated Ilow conveys runoff into Elliot Creek and existing ponds located north and south of site. 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. IDEM (317- 233 -5627) and the HCSWCD (317- 773 -1406) are to be notified within 48 hours of starting construction. 3. 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 perimeter of the overall site. See plans for specific locations. 4. Evaluate existing vegetation suitable for use as filter strips along the perimeter of the overall site. 5. Evaluate, mark and protect important trees and associated root zones. 6. Inlet protection shall be placed at the existing curb inlets located west of site along Horseferry Rood as depicted on plan. 7. A construction entrance shall be placed per the plan location. 8. Establish construction staging area for equipment and vehicles as for from detention ponds and swales as possible. 9. Establish onsite location for owner /operator /contractor placement of approved plans and Rule 5 NOI and Rule 5 inspection documentation. ESTABLISH SILT BASINS /TRAP: 10. Install two sediment traps labeled "A" and "B ". See Sheet C805 for details. See Sheet C102 for locations and proposed contours. 11. After completion of the sediment traps seed dams. 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. After completion of mass grading, final grade and seed landscape berms, common areas and swales immediately after grading is completed. 3. Upon completion of mass grading, install sanitary and storm sewers. As storm sewers are constructed, install inlet protection measures. Install riprop upon completion of end section Installation. 4. Upon completion of sewer installation and inlet protection, proceed with street construction. 5. Liming of streets should be done prior to the installation of storm sewers to prevent the transmission of lime dust to ponds or receiving waters. 6. Once pavement and curbs are in place, install curb inlet sediment barriers and re -seed all disturbed areas. 7. Once inlet protection is in place, final grade all areas. Upon completion of all grading, verify depth of pond per plan requirement, dredge as needed. B3 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, 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. 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 affects the site's potential for the discharge of regulated material. Prediction of Potential Spills: 1. Nearest Navigable Water: Elliot Creek 2. Drainage System: All storm drainage leaves the development site by swales and closed storm systems which eventually discharges into Elliot Creek which flows southeasterly. 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, point, herbicides and pesticides. 4. ndw r ter Contamination: G ou a 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 contamination. The facility does have city sanitary sewer and city water. Alert Procedures for Spills: 1. Any personnel observing a spill will immediately instigate the following procedure: a.) Dialing V 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 spill - Probable time of the spill - Volume of the spill and du7ction - Present and anticipated movement of the spill - Weather conditions - Personnel at the scene - Action initiated by personnel C.) Notify the City of Carmel Fire Department Phone: 9 -1 -1 d.) Notify the City of Carmel 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 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 / Homeowners Association shall be continually kept informed, maintain lists of qualified contractors and available Voc- 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 informed of the requirements and procedures outlined in this plan. They will be 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 soving 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 o f e Indiana Department o f Environmental Management. 5. Flushing of spilled material with water will not be permitted unless so authorized by the Indiana Department of Environmental Management. 9'1 Monitoring and maintenance guidelines for pollution prevention measures: Straw mM in Requirements S o w BoeI Da Maintenance R q ira eue ets 1.

Post construction water quality BMP's are to be installed during normal construction activies of this project defined within construction documents. A. Inspect and maintain all erosion control measures as detailed in the Stormwater Pollution Prevention Measures Maintenance Requirements beginning immediately after installation and continuing until vegetation has been sufficiently established and all construction activity is complete. B. Remove all individual inlet protection and straw bale dams, silt fences, etc. only after seeding and sufficient vegetative growth h as been estab li shed in each area to a point where sediment /pollutants will not enter the lakes or storm sewer system. C. Inspection and maintenance of all common areas and infrastructure improvements is the responsibility of the owner /developer or his designee until improvements are accepted for maintenance by homeowners association or local agencies. D. Inspection and maintenance of individual lots is the responsibility of the home builder or his designee until the homeowner buys and thereby accepts responsibility for the individual lot. Description of proposed post construction stormwater quality measures: Site and facility design for stormwater quality protection on this site employs a multi level strategy consisting of: 1. Reducing or eliminating post - project runoff. 2. Controlling sources of pollutants. 3. And if needed, treating contaminated stormwater runoff before discharging it into the storm sewer system or receiving waters. Stormwater quality measures for reducing, eliminating or controlling pollutants (source controls) include: a. Dention /Retention - Detain stormwater runoff an extended period of time to allow pollutants that are suspended to settle out. b. Reducing Runoff or Direct runoff from impervious areas - Reduction in volume of runoff potentially carrying suspended solids and pollutants. c. Vegetated strips and /or swales - Biological and chemical processes in soils and vegetation to filter out pollutants. d. Permanent erosion control seeding and plantings including landscaping and vegitative topsoil located in common areas - Biological and chemical processes in soils and vegetation to filter ou+ pollutants. e. Outlet protection & velocity dissipation devices such as rip rap- Prevent surface erosion resulting in decreased suspended solids and preserving established downstream vegetative cover. f.

ADDITIONAL STORMWATER POLLUTION PREVENTION MEASURES VEHICLE & EQUIPMENT MAINTENANCE Description and Purpose Prevent or reduce the contamination of stormwater resulting from vehicle and equipment maintenance by running a '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 providing cover for materials stored outside, checking 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 OCtIC01 t0 send vehicles and equipment offsite for 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 contaminate stormwater include engine repair and service, changing or replacement of fluids, and outdoor equipment storage and parking (engine fluid leaks). mplementation 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 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 impermeable surface in a dedic ated maintenance ntenance 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 P property. 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. 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 batteries. Do not bury used tires. Repair leaks of fluids and oil immediately. Listed 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. White 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 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. 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 only, 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 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 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 fueirg of mobile construction equipment around the site; rather, transport the equipment *.c aeslgnoted fueling areas. T. .r a employees a "d subcontractors in proper fueling and cleanup procedures. ;ed,cated fuelirg areas should be protected from stormwater runon and runoff, and should be ocated at least 5- ft away from downstream drainage facilities and watercourses. Fueling must be perfo -ec on level -grade areas. Protect fueling c-cs with berms and dikes to prevent runon, runoff, and to contain spills. Nczzies used it +er,cle and equipment fueling should be equipped with an automatic shutoff .c control drips �,eling operations should not be left unattended. Federal. state, and local requirements should be observed for any stationary above ground storage tanks. Inspection ors Mairtenance Vehicles or_ -:, v -ent should be inspected each day of use for leaks.

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 solid waste promptly since erosion and sediment control devices tend to collect litter. Make sure that toxic liquid wastes used oils, solvents, is and ants 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 ro� ct site should I P le s ou d be collected and laced in watertight 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. Dum ste r s of sufficient size and number should be P provided to contain th e 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 ponding. rapr' l i,le� te^crce Inspect and verify that activity -based BMPs ore 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. The following steps will help reduce stormwater pollution from concrete wastes: D,scuss the concrete 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 wet materials under cover, away from drainage areas. Av ^id 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. Y'NA-PI'IIJG AN19 P'1,VPINiS OPFRA`1C Description and Purpose Dewatering operations are practices ces t h at 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 construction 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 m h methods. Dewaterin 9 operations will require, and must comply with, applicable local permits. InnDlementation 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 stir ; ; - 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.

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 �C'SC'F' ,7. 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. 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 �A" ''','1','IC(:. Maintenance is required for vegetation, embankment, inlet and outfall structures, as well as other features.
