Assign an on -site person trained in erosion control proceedures with the daily responsibility and authority to ensure that erosion /sediment control practices are installed according to this sequence schedule. 327 LAC 15 -5 requires that a Pollution Prevention Plan monitoring log and permit information be posted at the project site. 2. Contact Indiana Underground Planned Protection Systems, Inc. ( "Holey Moley ") for underground Utility locations. (1- 800 - 382 -5544) 3. Before opening up the site, first evaluate, mark and protect important trees and associated root zones, uni ue areas to be preserved (i.e. wetlands), or existing vegetation suitable for use as filter strips especially in perimeter areas). 4. Install sediment basins or traps around the perimeter of the site and diversions above the site to direct water from undisturbed areas away from the sediment traps while conveying sediment -laden runoff from disturbed areas to the traps. 5. Install an adequate and stable construction entrance / exit drive from the construction site to keep mud and sediment off public roads. Dust shall be kept to a minimum by utilizing sprinkling, Calcium Chloride, vegetative cover, spray on adhesives or other approved methods. 6. Install the main runoff conveyance system with inlet and outlet protection devices to convey storm runoff through the site without creating gullies and to prevent damage to open channels. Sides of Swales, mounds and ponds to be seeded and mulched upon completion. Temporary seeding shall be required for all swales and disturbed areas that connot be final seeded within • time period that will prevent slope erosion. For temporary seeding, the contractor shall utilize • fast growing seed of either oats, annual rye grass, wheat or rye depending on time of year. Disturbed areas shall be kept to a minimum at all times. 7. As soon as the storm drain system is functional, install drain inlet protections, which trap sediment on -site in shallow pools while allowing high water flows to enter the system. 8. Once erosion and sediment control measures are in place, begin land clearing followed immediately by grading. Do not leave large areas unprotected for more than 7 days. 9. As grading progresses, install additional traps, silt fences, slope drains, temporary diversions, and other runoff control measures at appropriate locations to keep sediment contained on -site. 10. Immediately after grading, apply surface stabilization practices on all graded areas, using permanent measures in accordance with the erosion control plan. However, if weather delays permanent stabilization, temporary seeding and /or mulching may be necessary as a stop -qap measure. Also stabilize (using temporary seeding /mulching or other suitable means) any disturbed area where active construction will not take place for 30 working days. 11. After construction and final grading, landscape and permanently stabilize all disturbed sites, including borrow and disposal areas. Also remove temporary runoff control structures and any unstable sediment around them, and vegetate those areas.

THE BEST PRACTICE WOULD BE TO PERFORM MAINTENANCE ACTIVITIES AT AN OFFSITE FACILITY WHENEVER POSSIBLE. IF THIS OPTION IS NOT FEASIBLE, THEN WORK SHOULD BE PERFORMED ONLY IN DESIGNATED AREAS, WHILE PROVIDING ADEQUATE COVER FOR MATERIALS STORED OUTSIDE, ROUTINELY CHECKING FOR LEAKS AND SPILLS, AND CONTAINING AND CLEANING UP ALL SPILLS IMMEDIATELY, UITABLE APPLICATIO THESE PROCEDURES ARE APPLICABLE FOR ALL CONSTRUCTION PROJECTS WHERE AN ONSITE STAGING YARD AREA IS NECESSARY FOR THE STORAGE AND MAINTENANCE OF HEAVY CONSTRUCTION EQUIPMENT AND VEHICLES. KN. VEHICLE AND EQUIPMENT MAINTENANCE SHOULD ONLY BE PERFORMED ONSITE WHEN IT IS IMPRACTICAL TO SEND THEM OFFSITE FOR MAINTENANCE AND REPAIR. TRANSPORTING VEHICLES AND /EQUIPMENT OFFSITE SHOULD BE DONE ONLY AT THE STABILIZED CONSTRUCTION ENTRANCE /EXIT. VEHICLE STORAGE AND EQUIPMENT MAINTENANCE PROVIDES FOR A POTENTIALLY SIGNIFICANT SOURCE OF STORMWATER POLLUTION. ONSITE ACTIVITIES THAT CAN CONTAMINATE STORMWATER INCLUDE GENERAL MAINTENANCE SUCH AS CHANGING OR REPLACEMENT OF FLUIDS AND FILTERS, ENGINE REPAIR AND SERVICE, AND OUTDOOR EQUIPMENT STORAGE OR PARKING (FROM SOURCES SUCH AS THE ENGINE, OIL, FUEL, OR HYDRAULIC FLUID LEAKS). IMPLEMENTATION IF MAINTENANCE MUST OCCUR ONSITE, WORK SHOULD BE DONE ONLY IN DESIGNATED AREAS LOCATED AWAY FROM DRAINAGE COURSES. DEDICATED MAINTENANCE AREAS SHOULD BE PROTECTED FROM STORMWATER INFILTRATION AND RUNOFF. THE MAINTENANCE AREA SHOULD BE LOCATED AT LEAST 50 FEET FROM DOWNSTREAM DRAINAGE FACILITIES, WATERWAYS, AND FLOOD PLAINS. STORE AN ADEQUATE AMOUNT OF SPILL CLEANUP MATERIALS ONSITE WHERE THEY CAN BE READILY ACCESSIBLE. 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 WITHIN THE DEDICATED MAINTENANCE AREA USE ABSORBENT MATERIALS ON SMALL SPILL AREAS. REMOVE THE CONTAMINATED ABSORBENT MATERIALS PROMPTLY AND DISPOSE OF THEM PROPERLY. ALL FUELING TRUCKS AND FUELING AREAS SHALL HAVE SPILL KITS AND /OR USE OTHER ADEQUATE SPILL PROTECTION DEVICES. INSPECT ONSITE VEHICLES AND EQUIPMENT DAILY AT THE BEGINNING OF EACH DAY FOR LEAKS AND REPAIR IMMEDIATELY. KEEP VEHICLES AND EQUIPMENT CLEAN; DO NOT ALLOW EXCESSIVE BUILD -UP OF OIL, GREASE OR SILT MATERIALS THAT MAY CONTAMINATE OTHER PORTIONS OF THE SITE. EMPLOYEES AND SUBCONTRACTORS SHALL BE TRAINED IN PROPER MAINTENANCE AND SPILL MEDIATION PROCEDURES. PROPERLY DISPOSE OF USED OILS, FLUIDS, LUBRICANTS, AND SPILL CLEANUP MATERIALS PER LOCAL AND STATE LAWS. SEPARATE AND RECYCLE WASTES SUCH AS GREASES, USED OIL, HYDRAULIC FLUID, OIL T BATTERIES, FILTERS, ANTIFREEZE, CLEANING SOLVENTS, TT S, AND TRANSMISSION FLUIDS. IF THESE MATERIALS ARE STORED ONSITE, PROVIDE ADEQUATE SECONDARY CONTAINMENT AND COVERS. DO NOT PLACE USED OIL IN AN UNAPPROVED DUMPSTER, POUR INTO A STORM DRAIN OR WATERCOURSE, OR POUR ONTO THE GROUND. DRIP PANS OR PLASTIC SHEETING SHOULD BE PLACED UNDER ALL VEHICLES AND EQUIPMENT WATER BODIES E PLACED ON WATERWAY DOCKS, BARGES, OR OTHER STRUCTURES LOCATED OVE R W WHEN THE VEHICLE OR EQUIPMENT IS ANTICIPATED TO BE IDLE FOR MORE THAN ONE HOUR. DO NOT BURY OR BURN USED TIRES. SOLID WASTE MANAGEMENT TION AND PURPOS SOLID WASTE MANAGEMENT PROCEDURES AND PRACTICES ARE DESIGNED TO PREVENT OR REDUCE THE POTENTIAL FOR DISCHARGE OF POLLUTANTS TO STORMWATER FROM SOLID OR CONSTRUCTION WASTE BY PROVIDING DESIGNATED WASTE COLLECTION AREAS AND CONTAINERS, ENSURING REGULAR DISPOSAL, AND TRAINING OF EMPLOYEES AND SUBCONTRACTORS. SUITABLE APPLICATIONS THIS PRACTICE IS APPLICABLE FOR CONSTRUCTION SITES WHERE THE FOLLOWING WASTES ARE GENERATED OR STORED: SOLID WASTE GENERATED FROM DEMOLITION ACTIVITIES SUCH AS TREES OR SHRUBS, DEMOLITION OF EXISTING STRUCTURES, AND NEW BUILDING CONSTRUCTION MATERIALS INCLUDING CONCRETE, MASONRY, WOOD, METAL, GLASS, RUBBER, STYROFOAM, PAPER, PLASTIC, PIPE, ELECTRICAL COMPONENTS, AND PACKAGING MATERIALS. DOMESTIC WASTES INCLUDE: FOOD CONTAINERS, BEVERAGE CONTAINERS, COFFEE CUPS, PAPER BAGS, PLASTIC WRAPPERS, STYROFOAM, AND CIGARETTES. CONSTRUCTION WASTES INCLUDING BRICK, MORTAR, TIMBER, STEEL AND METAL SCRAPS, PIPE AND ELECTRICAL CUTTINGS, NONHAZARDOUS EQUIPMENT PARTS, STYROFOAM AND OTHER MATERIALS SEND TRANSPORT AND PACKAGE CONSTRUCTION MATERIALS. IMPLEMENTATION THE FOLLOWING STEPS WILL AID IN KEEPING THE SITE CLEAN AND REDUCE THE POTENTIAL FOR STORMWATER POLLUTION: SELECT A DESIGNATED WASTE COLLECTION AREA ONSITE THAT IS DOWNSTREAM FROM THE STORMWATER COLLECTION SYSTEM AND AT LEAST 50 FEET AWAY FROM ALL WATERWAYS AND FLOOD PLAINS. INFORM THE TRASH- HAULING CONTRACTOR THAT ONLY WATERTIGHT DUMPSTERS FOR ONSITE USE WILL BE ACCEPTED. INSPECT DUMPSTERS WHEN THEY REACH THE SITE FOR LEAKS. REJECT ANY DUMPSTER THAT IS NOT WATERTIGHT OR IS DEFECTIVE. PROVIDE AN ADEQUATE NUMBER OF CONTAINERS WITH LIDS OR COVERS TO KEEP RAINWATER OUT AND TO PREVENT LOSS OF MATERIALS DUE TO WINDY CONDITIONS. ALLOW FOR ADDITIONAL DUMPSTERS OR MORE FREQUENT PICKUPS DURING THE DEMOLITION PHASE OF CONSTRUCTION TO INSURE TRASH MATERIALS DO NOT GET STORED ON THE GROUND. HAVE SITE TRASH COLLECTED DAILY, DURING RAINY AND WINDY CONDITIONS IT MAY BE NECESSARY TO COLLECT TRASH MORE THAN ONCE A DAY. REMOVE SOLID WASTE MATERIALS PROMPTLY FROM THE SITE SINCE EROSION AND SEDIMENT CONTROL MEASURES TEND TO COLLECT TRASH WHICH HINDERS THE EFFECTIVENESS OF THE EROSION CONTROL MEASURES. INSURE THAT TOXIC LIQUID WASTES SUCH AS USED OILS, SOLVENTS, AND PAINTS AND CHEMICALS SUCH AS ACIDS, PESTICIDES, ADDITIVES, AND CURING COMPOUNDS ARE NOT DISPOSED OF IN DUMPSTERS DESIGNATED FOR CONSTRUCTION DEBRIS BUT ARE PROPERLY DISPOSED OF ACCORDING TO LOCAL AND STATE LAWS. DO NOT WASH OUT DUMPSTERS ON THE CONSTRUCTION SITE. DUMPSTER CLEANING SHOULD BE THE RESPONSIBILITY OF THE TRASH HAULING CONTRACTOR. ARRANGE FOR REGULAR WASTE COLLECTION BEFORE DUMPSTERS OVERFLOW. DO NOT PILE MATERIAL ABOVE THE DUMPSTER SIDE OR ALLOW MATERIAL TO DRAPE OVER THE SIDES. IMMEDIATELY CLEAN UP DUMPSTER SHOULD A SPILL OCCUR.
