STORMWATER POLLUTION PREVENTION CHECK LIST SECTION B Da Material handling and spill prevention plan: Purpose: The intention of this Spill Prevention, Control and Countermeasures (SPCC) is to establish the procedures and equipment required to prevent the discharge of oil and hazardous substances in quantities that violate applicable water quality standard3, cause a sheen upon or discoloration of the surface of navigable waters 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. 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 storm water (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: White River 2. Drainage System: The site will drain southeast to existing Wellbaum regulated drain. Wellbaum Regulated Drain flows to White River. All storm drainage leaves the site by a closed storm sewer pipe outlet. 3. Possible Spill Sources: Vehicular sources such as leaking fuel or oil, brake fluid, grease, antifreeze; construction trash and debris, biological agents found in trash and debris, fertilizers, 4. Groundwater Contamination: There will be NO above ground or under ground storage tanks or facilities at this site. The facility will not use domestic water or sanitary services.

If fence fabric tears, starts to decompose, or in any way becomes ineffective, replace the affected portion immediately. Alert Procedures for Spills: t 1. Any personnel observing a spill will immediately initiate 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 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 Fire Department Phone: 9-1-1 d.) Notify the 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/Contractor shall be continually kept informed and 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 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 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. 3. Remove deposited sediment when it reaches half the height of the fence at Its lowest poln or is causing the fabric to bulge. 4. Take care to avoid undermining the fence during clean out. 5. After the contributing drainage area has been stabilized, remove the fence and sediment deposits, bring the disturbed area to grade, and stabilize. Erosion Control Blanket Requirements: Material: As specified on plans or approved equal. Anchoring: Per manufacturer's recommendations for intended use or per plan specifications. Installation: 1. Select the type and weight of erosion control blanket as directed on plans. 2. Grade the site as specified in the construction plans. 3. Add topsoil where appropriate. 4. Prepare the seedbed, fertilize (and lime, if needed), and seed the area immediately after grading. 5. Following manufacturers directions, lay the blankets on the seeded area such that they are in continuous contact with the soil and that the upslope or upstream ones overlap the lower ones by at least 8 in. 6. Tuck the uppermost edge of the upper blankets into a check slot (slit trench), backfill with soil, and tamp down. 7. Anchor the blankets as specified by the manufacturer or as specified in the plans. Maintenance: 1. During vegetative establishment, inspect after each storm event for any erosion below the blanket. 2. If any area(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 Construction Entrance/Exit Pad Requirements: 1. The construction entrance shall be located off of Dalmon Road. If muddy conditions result in tracking on Road, clean up immediately and add "wheel wash area." 2. Material for Gravel Construction entrance and/or Wheel Wash Area: 2-3 in. washed stone (INDOT CA No. 2) over a stable foundation. Thickness: 8 in. minimum 3. Width: 30 ft. minimum or full width of entrance/exit roadway, whichever is greater. 4. Length: 150 ft. or as the site will accommodate minimum. The length can be shorter for small sites. 5. Washing Facility. Level area with 3 in. washed stone minimum or a commercial rack, and waste water diverted to a protected area such as a sediment trap, basin, or area protected by coir logs. 6. Geotextile fabric underliner: May be used under wet conditions or with soils with a high seasonal water table to provide greater bearing strength. Installation: 1. Avoid locating on steep slopes or at curves in public roads. 2. Remove all vegetation and other objectionable material from the foundation area. Grade and crown for positive drainage. 3. If slope towards the road exceeds 2%, construct a 6-8 in. high water bar (ridge) with 3:1 side slopes across the drive area about 15 ft. from the entrance to divert runoff away from the road into protected sediment basins. 4. Install pipe under the drive if needed to maintain proper public road drainage. 5. Place geotextile fabric on the ground foundation prior to stone placement to improve stability. 6. Place stone to dimensions and grade shown in the erosion and sediment control plan, leaving the surface smooth and sloped for drainage. 7. Divert all surface runoff and drainage from the stone drive to a sediment trap or basin. Maintenance: 1. Inspect entrance drive and sediment disposal area weekly and after storm events or heavy use. 2. Reshape drive as needed for drainage and runoff control. 3. Top dress 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 the water is conveyed into a sediment trap or basin. 5. Repair any broken road pavement immediately. Riprap Requirements: 1. Rock: Hard, angular, and weather -resistant, having a specific gravity of at least 2.5. Gradation: Well -graded stone, 50% (by weight) larger than the specified d50, and no more than 15% of the pieces (by weight) should be less than 3 in. Filter: Use geotextile fabric for stabilization and filtration or sand/gravel layer placed under all permanent riprap installations. Slope: 2:1 or flatter, unless approved in the erosion and sediment control plan. Minimum Thickness: three times the specified d50 stone diameter. Installation: Subgrade Preparation: 1. Remove brush, trees, stumps, and other debris. 2. Excavate only deep enough for both filter and riprap; over -excavation increases the amount of spoil considerably. 3. Compact any fill material to the density of the surrounding undisturbed soil. 4. Cut a keyway in stable material at the base of the slope to reinforce the toe; keyway depth should be 1-1/2 times the design thickness of the riprap and should extend a horizontal distance equal to the design thickness. 5. Smooth the graded foundation. Filter Placement: 1. If using geotextile fabric, place it on the smoothed foundation, overlap the edges at least 12 in., and secure with anchor pins spaced every 3 ft. along the overlap. 2. If using a sand/gravel filter, spread the well -graded aggregate in a uniform layer to the required thickness (6 in. minimum); if two or more layers are specified, place the layer of smaller gradation first, and avoid mixing the layers. Riprap Placement: 1. Immediately after installing the filter, add the riprap to full thickness in one operation. (Do not dump through chutes or use any method that causes segregation of rock sizes or that will dislodge or damage the underlying filter material.) 2. If fabric is damaged, remove the riprap and repair by adding another layer of fabric, overlapping the damaged area by 12 in. 3. Place smaller rock in voids to form a dense, uniform, well -graded mass. (Selective loading at the quarry and some hand placement may be needed to ensure an even distribution of rock material. 4. Blend the rock surface smoothly with the surrounding area to eliminate protrusions or overfalls. Maintenance: 1. Inspect periodically for displaced rock material, slumping, and erosion at edges, especially downstream or downslope. (Properly designed and installed riprap usually requires very little maintenance if promptly repaired.) B15 Erosion & sediment control specifications for individual building lots: NONE STORMWATER POLLUTION PREVENTION PLAN INDEX SECTION C Cl Description of pollutants and their sources associated with the proposed land use: Silt and sediment from exposed soils, leaves, mulch, vehicular sources such 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 but not limited to cleaning agents, chemicals, paint, miscellaneous home improvement materials, toys, clothing and animal waste, elevated storm runoff temperatures, acid rain pesticides and pathogens. C2 Sequence describing storm water quality measure implementation: 1. Inspect and maintain all erosion control measures as detailed in the Storm Water Pollution Prevention Measures Maintenance Requirements beginning immediately after installation and continuing until vegetation has been sufficiently established and all construction activity is complete. 2. Remove all individual inlet protection and coir log check dams, silt fences, etc. only after seeding and sufficient vegetative growth has been established in each area to a point where sediment/pollutants will not enter the downstream ditch and creek system. 3. It is recommended that any proposed wetland areas and plantings (if any) be constructed/placed after final grading and sufficient vegetative growth has been established to a point where sediment/pollutants will not enter the proposed wetlands. C3 Description of proposed post construction storm water quality measures: Site and facility design for storm water quality protection on this site employs a multi-level strategy consisting of: 1. Controlling sources of pollutants. 2. And treating contaminated storm water runoff before discharging it into the adjacent regulated drain. Storm water quality measures for reducing, eliminating or controlling pollutants (source controls) include: 1. Grass Filter Strip: This BMP will filter and encourage infiltration while runoff is still in sheet flow. 2. Vegetated Swale: This BMP will filter runoff and encourage infiltration. 3. Extended Dry Detention Basin: This BMP will delay runoff long enough to encourage suspended solids to drop out before runoff enters regulated drain. 4. Permanent erosion control seeding and plantings 5. Outlet protection & velocity dissipation devices 6. Mulching It is the intent of this plan that the implementation of the above described storm water quality measures be executed in accordance with the enclosed plans and details in order to meet the requirements of Rule 5 storm water quality.
