The sequencing is specified on this sheet.(See seasonal soil protection chart on this sheet). 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. 1. Construction Equipment a. Fueling, lubrication and fluids: All operations involving the addition of fluids to equipment should be done in one location, as designated on Sheets C300 -C301, 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.

B13 cont. 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 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. If the use of lime is used to stabilize the soil of the site then all construction equipment used shall be cleaned of all excess material with water in the maintenance and refueling area as shown within these plans. e. 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 waster water shall be disposed of in the designated area as shown on Sheets C300 -C301. This area is a 4' high, 10' diameter doughnut type mulch berm which shall be constructed over a geotextile fabric. 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 there related products shall be disposed of in the manner at which the manufacturer suggest. Under NO circumstances will paint or their related products be cleaned or disposed of in soil, sanitary sewers, storm sewers or detention basins. Any violation of this shall be reported to the job superintendent. In the event of small spills please contact the construction supervisor. In the event of spills that require removal of soils or other materials, please contact the construction supervisor, developer, County Surveyor's Office and the Local Fire Department. In the event of spills that have potential groundwater or surface water contamination, please contact the construction supervisor, developer, County Surveyor's Office, Local Fire Department and IDEM. See 0 M Manual for all Emergency Numbers. B14. Monitoring and Maintenance Guidelines for Each Proposed Pollution Prevention Mea sure: Person in charge of and knowledgeable about erosion and sediment control shall inspect the site for stormwater pollution prevention deficiencies at least daily and again within 24 hours of every 1/2 inch rain event. See Erosion Crontrol Notes on this sheet for specifications. B15. Erosion and Sediment Control Specifications For Individual Building Lots: Construction sequence for individual building lots is shown on this sheet. Stormwater Pollution Prevention Plan Post Construction Component Cl. Description of Pollutants and Their Sources Associated with the Proposed Land Use: Proposed site will be a residential subdivision. Potential pollutants from this type of development include, but are not limited to: fluids and debris from parked vehicles vehicular traffic which could include: fossil fuels, oil, grease, antifreeze, brake fluid, window washer fluid, rubber, plastic, metal fragments, grit (sediment) from wearing of the road surface, trash (including bacteria and other biological agents contained in the trash) from littering and other types of improper disposal or storage, and elevated receiving water temperatures from stormwater runoff contact with impervious surfaces. C2. &C3. Sequence Describing Stormwater Quality Measure Implementation: Description of Proposed Post Construction Stormwater Quality Measures: The post construction measures used to minimize sedimentation in waterways include swales and detention ponds. These detentions ponds have been designed with temp basins. The swales in conjunction with the basins will collect runoff from the buildings and a majority of the pavement. The design of the swales will allow sediment to be partially infiltrated before storm water enters the designed storm sewer system. Beehive inlets will prevent large items from entering the storm pipes and leaving the site. The detentions basins, which is designed to have water in it at all times, will also help reduce sediment and trash by allowing it to drop out prior to leaving the site. The owner also desires to keep some of the wooded part of the site undisturbed during and after construction, allowing existing vegetation to help remove sediment during and after construction. C4. Location, Dimensions, Specifications and Construction Details of Each Stormwater Quality Measures: Catch basins, swales, and lake locations are provided on the site development plans. Details are provided on the Construction Plan Detail sheets. C5. Description of Maintenance Guidelines for Proposed Post Construction Water Quality Measures: Maintenance of all Stormwater pollution prevention measures will be the responsibility of the project owner, Platinum Properties until a point in time in which the Home Owners Association is established. At that point said association shall assume all maintenance responsibilities. The maintenance guidelines consist mostly of good housekeeping measures. Any grassed or vegetated areas that experience erosion from rainfall events should be repaired and revegetated as soon as possible. Trash or litter should be picked up and properly disposed to prevent it from getting into the storm drainage system and downstream waterways. Erosion of the detention banks should be addressed as soon as it becomes visible by filling the eroded area with suitable soil and establishing vegetation immediately, preferably by sodding, or by seeding and mulching and monitoring until suitable vegetation is established. The same measure should be used for steep banks of any earth berm or any other steep area. The detention basin should also be monitored for sediment coming from the storm drainage system. If the bottom of the basin receives sediment, indicated by the sediment markers, it should be cleaned out and the source found and repaired. The elevation of the basin bottom should be checked every 2 to 5 years and, if significant sediment is encountered, it should be removed from the basin. This should be done during periods of low rainfall to allow soil stirred up by excavation to settle out before a rain event. The detention basin outlet should also be protected by adequate filtration (rip -rap, shown on these plans) to prevent soil from entering the offsite storm drainage system. Pavement areas should also be monitored for pollutants. Any large quantity of fluids such as oil, antifreeze, brake fluid, etc. found on the pavement should be reported to the Home Owner Association and the source determined, if possible, and removed from the site for maintenance or repair. Pavements should also be monitored for sediment coming from vegetated areas that drain onto the pavement. If sediment is found it should be cleaned off the pavement, and the source of the soil found and repaired as discussed above. Copy of the post water quality booklet shall be provided to the Home Owner Association for references to certain FDA requirements. Copy shall be onsite at the posting information station.

Fill geotextile bags approximately half full with 2 to 3 inch stone or mulch. 2. At a position downslope of the lot and upslope of the inlet, lay bags tightly in a row curving upslope from curb and away from inlet. 3. Overlap bags onto the curb and extend a min- imum of 3 feet into the street. 4. For additional layers, overlap bags with the row beneath, and leave a one -bag gap in the middle of the top row to serve as a spillway. 5. Place bags in an arc around curb inlets that are in a sump position. 6. Set up safety /traffic barriers to keep vehicles from hitting bags, causing possible injury. 7.
