B13 Material handling and spill prevention plan: In order to minimize the release of potential pollutants during construction the Contractor shall implement this material handling and spill prevention plan. The Contractor shall review this plan with all subcontractors and require that they implement the plan as well. Possible materials on site include fueling, equipment repair or service, dewatering, dust control, paints and solvents, solid waste and concrete washout. 1. Construction Equipment a. Fueling, lubrication and fluids: All operations involving the addition of fluids to equipment should be done in one location, so that spills are limited to one location on the Site, which will facilitate the cleanup of spills. If an onsite fueling tank is planned to be on site, it shall be double walled and stored in this designated area. This location is an area that will not allow spilled fluids to migrate into subsurface soils. In the event of a spill, the fluid shall immediately be cleaned up by removing the contaminated soil or stone which shall be disposed of in an acceptable manner. Spills on hard surfaces shall be soaked up by an acceptable material such as Oil Dry and the absorbent material disposed of in a proper manner. The spill shall also be reported immediately to the Contractor's superintendent. b. Equipment repair, especially when fluids must be removed from the equipment or the possibility of fluid spills is high, should always be done offsite at a facility that is more suitable than a construction site to handle spills. When equipment must be repaired onsite it should be moved to the maintenance and fueling area if possible. Otherwise, suitable on site containers should be placed under the equipment during repair to catch any spilled fluids and these fluids should be disposed of in a proper manner. c. All reusable fluid containers, such as gasoline cans, shall be inspected for leaks each time they are used. If leaks are found, the fluid shall be removed from the container in a proper manner and the container disposed of in an acceptable manner. Empty disposable containers, such as grease tubes and lubricating oil and brake fluid containers, and their packaging, shall be disposed of in a proper manner and shall not be left on the ground or in the open on the construction site. 2. Construction Materials and their Packaging a. Erosion control measures shown on these plans shall be implemented prior to and during construction in the proper sequencing to minimize soil erosion. Erosion controls shall be inspected and maintained as described elsewhere in these plans. Excessive dusting of soil on the site shall be minimized by reducing construction traffic across bare soil during dry and /or windy weather, and by applying water or other acceptable dust control measures to the soil. Upon completion of construction and suitable establishment of permanent vegetation, temporary erosion control measures such as silt fence, check dams and inlet protection devices shall be removed in a manner to minimize additional land disturbance. Any areas disturbed by these operations shall be properly revegetated. b. Large waste materials created by cutting, sawing, drilling, or other operations shall be properly disposed of in suitable onsite waste containers. The site shall be checked at the end of the day, as a minimum, and all waste materials, including those blown across or off the site by wind, shall be picked up and disposed of in suitable containers. Where possible, operations such as sawing that create small particles should be performed in one spot in an area protected from wind, and waste particles collected and disposed of frequently to minimize wind dispersal. Packaging used to transport materials to the site for construction of the facility shall be disposed of properly, whether the material is taken out of its package and incorporated into the project immediately or stored onsite for future use. Packaged materials stored onsite shall be inspected regularly and any loose packaging shall be repaired or disposed of properly. c. All dewatering of activities shall be done in accordance to good erosion control practices. These practices should include the use of dirt bags such as Dandy Dirt Bags. The use of these types of dewatering devices will remove large quantities of silt, sediment and dirt and prevent these materials to enter the storm sewer system. d. Nutrients and fertilizers shall only be used to establish rapid vegetation. When these products are utilized, the user should pay strict attention to the products recommended usage. 3. Concrete Waste Water a. All concrete waste water shall be disposed of in the designated area. See concrete wash -out detail. This area shall be inspected on a daily basis as a minimum. When this area becomes full, the pollutants shall be excavated, placed in an acceptable container and disposed of in a proper manner. 4. Paint Products a. All excess paint and their related products shall be disposed of in the manner at which the manufacturer suggests. Under NO circumstances will paint or their related products be cleaned or disposed of in soil, sanitary sewers, storm sewers, detention basins or burned. Any violation of this shall be reported to the job superintendent. Procedures for spills: 1. Barricade the area allowing no vehicles to enter or leave the spill zone. 2. Notify the Carmel Fire Department. 3. Notify the Indiana Department of Environmental Management, Office of Emergency Response by calling (317) 233 -7745 or (888) 233 -7745. 4. Notify the Carmel construction inspectors. 5. Notify waste recovery contractor, maintenance personnel or other personnel as necessary for cleanup. 6. Coordinate and monitor cleanup until complete. 7. Cooperate with the IDEM -OER on procedures and reports involved with the event. B14 Maintenance guidelines are shown on the erosion control plan sheet and this sheet. B15 All construction occurs over two parcels. The drive at the northwest corner of the lot connects the lot to the west. Both lots are owned by the same owner (but different companies). The two lots are used as a single lot. STORMWATER POLLU11ON PREVENTION PLAN POST CONSTRUCTION COMPONENT Cl Potential pollutants on this site are oil, fuel, and other fluids from vehicles, trash, and vegetation control chemicals. C2 After construction, storm water quality BMP's will address pollutants from the parking lot (hard surfaces). Some sediment, but mostly hydrocarbon and heavy metal pollutants are expected. after major rainfall events or quarterly at a minimum. C3 The post construction storm water quality measures are an AS -2 Aquaswirl and a forebay /stilling basin. C4 See the construction plan sheets for BMP locations. C5 Copies of all inspection and maintenance reports for all site BMP's must be sent to the City of Carmel inspectors.

INSTALLATION 1. Location and Layout A. Locate the sediment trap as near to the sediment source as topography allows. B. Lay out the location and shape of the sediment trap allowing for a length to width ratio of 2:1 or greater. C. Locate concentrated storm water inflows as far away from the sediment trap outlet as possible. D. Where applicable, divert runoff from adjoining, undisturbed areas away from the sediment trap and install downstream sediment control measures to prevent off-site damages during construction of the sediment trap. 2. Embankment A. Clear, grub, and strip all vegetation and root mat from the embankment area. B. Construct the embankment in six to eight -inch lifts, compacting each lift as it is placed. Construct the embankment with 2:1 or flatter side slopes. (Material used to construct the embankment must be a stable mineral soil that is free of rocks, brush, roots, and other debris. The soil material must be wet enough to form a ball without crumbling, yet not so wet that water can be squeezed out of it. Place the most permeable soil material in the downstream toe of the embankment and the least permeable material in the center and on the up slope side of the embankment. To improve stability of the stone spillway, 3:1 side slopes are recommended for the embankment back slope.) C. Construct the embankment six inches above design elevation to allow for settling. 3. Outlet A. Excavate a trapezoidal outlet section in the compacted embankment Excavate the outlet section to the base of the pool area. B. Install geotextile fabric in the trapezoidal outlet section, extending the fabric up the sides of the outlet section to the top of the embankment. C. Place INDOT revetment riprap to the lines and grades shown in the construction plans, working smaller stones into voids to achieve a dense mass. The spillway crest must be level with a minimum depth of 12 feet, measured from the highest stones in the spillway weir notch to the top of the dam. D. Cover the upstream face of the riprap outlet section with a 12 -inch thick layer of INDOT CA No. 5 aggregate (for filtration). E. On the downstream side of the spillway, construct an outlet apron at the toe of the embankment Construct the apron to the lines and grade shown in the construction plans. Note: Outlet apron length must extend to a stable area of the stream channel. F. Place geotextile fabric or aggregate bedding material on the compacted and smoothed foundation and install riprap to the lines and elevations shown in the construction plans. Construct a small plunge pool within the outlet apron. (Riprap aprons must be level with or slightly lower than the receiving channel and should not produce an overfall or restrict flow of the water conveyance structure.) Stabilize the embankment and other disturbed areas with seed and mulch (anchored in place) or another suitable erosion resistant cover. G. Place a sediment cleanout reference stake at the 50 percent design volume elevation of the sediment trap. MAINTENANCE 1. Inspect within 24 hours of a rain event and at least once every seven calendar days. 2. Check the embankment for erosion and piping holes; repair immediately. 3. Check pool area side slopes for erosion, repair immediately. 4. Remove sediment when it has accumulated to one -half the design volume. 5. Replace spillway aggregate facing if the sediment pool does not dewater (drain) within 48 to 72 hours following a storm water runoff event. 6. Inspect vegetation; reseed if necessary. 7. Check spillway depth periodically to ensure a minimum depth of 12 feet from the lowest point of the settled embankment to the highest point of the spillway crest; fill any low areas to maintain design elevation. 8. Promptly replace any displaced riprap, being careful that no stones in spillway are above design grade. 9. After all disturbed areas have been stabilized, remove accumulated sediment and the embankment structure, smooth the site to blend with adjoining areas, and stabilize with seed and mulch or another appropriate nonerosive cover.

Plan for the fence to be at least 10 ft. from the toe of the slope to provide a sediment storage area. 2.) Provide access to the area if sediment cleanout will be needed. Fence Construction 1.) Along the entire intended fence line, dig an 8 in. flat bottomed or V- shaped trench. 2.) On the downslope side of the trench, drive the wood or steel support posts at least 1 ft. into the ground (the deeper the better), spacing them no more than 8 ft. apart if the fence is supported by wire or 6 ft. if extra strength fabric is used without support wire. Adjust spacing, if necessary, to ensure that posts are set at the low points along the fence line. (Note: If the fence has pre- attached posts or stakes, drive them deep enough so that the fabric is satisfactorily in the trench as described in Step 6.) 3.) Fasten support wire fence (if the manufacturer recommends its use) to the upslope side of the posts, extending it 8 in. into the trench. 4.) Run a continuous length of geotextile fabric in front (upslope) of the support wire and posts, avoiding joints, particularly at low points in the fence line. 5.) If a joint is necessary, nail the overlap to the nearest post with lath. 6.) Place the bottom 1 ft. of fabric in the 8 in. deep trench, extending the remaining 4 in. toward the upslope side. 7.) Backfill the trench with compacted earth or gravel. MAINTENANCE 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 its lowest point 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.

IN 47725 000- 772 -2040 1111/114110,11411.00111 Prepare soil before installing rolled erosion control products (RECP's), including any necessary application of lime, fertilizer, and seed. Note: When using cell -o -seed do not seed prepared area. Cell -o -seed must be installed with paper side down. Begin at the top of the slope by anchoring the reop's in a 6" (15 cm) deep x 6" (15 cm) wide trench with approximately 12" (30cm) of RECP's extended beyond the up -slope portion of the trench. Anchor the RECP's with a row of staples /stakes approximately 1 2" (30 cm) apart in the bottom of the trench. Backfill and compact the trench after stapling. Apply seed to compacted soil and fold remaining 12" (30 cm) portion of RECP's back over seed and compacted soil. Secure RECP's over compacted soil with a row of staples /stakes spaced approximately 1 2" (30 cm) apart across the width of the RECP's. Roll the RECP's (a.) down or (b.) horizontally across the slope. RECP's will unroll with appropriate side against the soil surface. all RECP's must be securely fastened to soil surface by placing staples /stakes in appropriate locations as shown in the staple pattern guide. When using the Dot System (TM), staples /stakes should be placed through each of the colored dots corresponding to the appropriate staple pattern. The edges of parallel RECP's must be stapled with approximately 2" 5" (5 cm 12.5 cm) overlap depending on RECP's type. Consecutive RECP's spliced down the slope must be placed end over end (shingle style) with an approximate 3" (7.5 cm) overlap. Staple through overlapped area, approximately 12" (30 cm) apart across entire RECP's width. Note: in loose soil conditions, the use of staple or stake lengths greater than 6" (15 cm) may be necessary to properly secure the RECP's. Site Preparation: Permanent Seeding Details (PS) REQUIREMENTS Site and seedbed preparation: Graded, and lime and fertilizer applied. Plant species: Selected on the basis of soil type, soil pH, region of the state, time of year, and planned use of the area to be seeded. Mulch: Clean grain straw, hay, wood fiber, etc., to protect seedbed and encourage plant growth. The mulch may need to be anchored to reduce removal by wind or water, or erosion control blankets may be considered. APPLICATION Permanently seed all final grade areas (e.g., landscape berms, drainage swales, erosion control structures, etc.) as each is completed and all areas where additional work is not scheduled for a period of more than a year. 1.) Install practices needed to control erosion, sedimentation, and runoff prior to seeding. These include temporary and permanent diversions, sediment traps and basins, and silt fences, (refer to Indiana Handbook for Erosion Control in Developing Areas, Practices 3.21, 3.22, 3.72, 3.73, and 3.74). 2.) Add topsoil to achieve needed depth for establishment of vegetation (refer to Indiana Handbook for Erosion Control in Developing Areas, Practice 3.02). 3.) Grade the site and fill in depressions that can collect water. Seedbed Preparation: 1.) Test soil to determine pH and nutrient levels. (Contact your county SWCD or Cooperative Extension office for assistance and soils information, including available testing services.) 2.) If soil pH is unsuitable for the species to be seeded, apply lime according to test recommendations. 3.) Fertilize as recommended by the soil test. If testing was not done, consider applying 400 -600 lbs. /acre of 12 -0 -12 analysis, or equivalent, fertilizer. Do not use phosphorous containing fertilizer unless soil teats indicate a soil phosphorous deficiency. 4.) Till the soil to obtain a uniform seedbed, working the fertilizer and lime into the soil 2 -4 in. deep with a disk or rake operated across the slope. Seeding: Optimum seeding dates are Mar. 1 -May 10 and Aug. 10 -Sept. 30. Permanent seeding done between May 10 and Aug.10 may need to be irrigated. As an alternative, use temporary seeding (refer to Indiana Handbook for Erosion Control in Developing Areas, Practice 3.11) until the preferred date for permanent seeding. 1.) Based on site conditions, soil pH, intended land use, and expected level of maintenance, select a seeding mixture and rate from the table below. 2.) Apply seed uniformly with a drill or cultipacker- seeder or by broadcasting, and cover to a depth of 1/4 -1/2 in. 3.) If drilling or broadcasting, firm the seedbed with a roller or cultipacker. 4.) Mulch all seeded areas (refer to Indiana Handbook for Erosion Control in Developing Areas, Practice 3.15). Consider using erosion control blankets on sloping areas (refer to Indiana Handbook for Erosion Control in Developing Areas, Practice 3.17). (NOTE: If seeding is done with a hydroseeder, fertilizer and mulch can be applied with the seed in a slurry mixture.) This table provides several seeding options. Additional seed species and mixtures When selecting a mixture, consider site conditions, including soil properties (e.g., slope aspect and the tolerance of each species to shade and droughtness Seed species and mixtures Rate per acre Optimum soil pH Open And Disturbed Areas (remaining Idle More 1 Yr.) 1.

Tall fescue provides little cover for, and may be toxic to, some species of wildlife. The IDNR recognizes the need for additional research on alternatives to tall fescue, such as buffalograss, orchard grass, smooth bromegrass, and switch grass. This research, in conjunction with demonstration areas, should focus on erosion control characteristics, wildlife toxicity, turf durability, and drought resistance. NOTE: An oat or wheat companion or nurse crop may be used with any of the above permanent seeding mixtures. If so, it is best to seed during the fall seeding period, especially after Sept.15, and at the following rates: spring oats- 1/4 to 3/4 bu. /acre; wheat -no more than Xz bu. /acre. MAINTENANCE 1.) Inspect periodically, especially after storm events, until the stand is successfully established. (Characteristics of a successful stand include: vigorous dark green or bluish -green seedlings; uniform density with nurse plants, legumes, and grasses well intermixed; green leaves; and the perennials remaining green throughout the summer, at least at the plant base.) 2.) Plan to add fertilizer the following growing season according to soil test recommendations. 3.) Repair damaged, bare, or sparse areas by filling any gullies, re- fertilizing, over- or re- seeding, and mulching. 4.) If plant cover is sparse or patchy, review the plant materials chosen, soil fertility, moisture condition, and mulching; then repair the affected area either by over seeding or by re- seeding and mulching after re- preparing the seedbed. 5.) If vegetation fails to grow, consider soil testing to determine acidity or nutrient deficiency problems. (Contact your SWCD or Cooperative Extension office for assistance.) 6.) If additional fertilization is needed to get a satisfactory stand, do so according to soil test recommendations. STABILIZATION PRACTICE: JAN. FEB. MAR. APR. MAY JUNE JULY AUG. SEPT. OCT. NOV. DEC.
