The besi optlon would be to perform maintenonce activities at an offsite facility. If thls option is not available then work should be per(ormed in designated areas only, while providing cover for materials stored outside, checking tor leaks and spills, and contoining ond cleaning up spills immediately. Suitable Aoolications These procedures are suitable on oll construction projects where an onsite yard area is necessary for storage and maintenance of heary equipment and vehicles. Limilations Onsite vehicle and equipment maintenance should only be used where it is impractical to send vehlcles and equipment offsite for maintenance antl repair. Sentling vehides/equlpment offsite should be done in conjunction wilh a Slabilired Construction Entrance/Exit. Ouldoor vehide 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�. Imolementation If maintenance must occur onsite, use designated areas, located away from drainage courses. Dedlwted maintenance areas should be proteded irom stormwater runon and runo(f, and should be bcated at least 50 ft from downstream drainage facilities and watercwrses. Drip pans or absorbent pads should be used during vehicle and equipment maintenance work that imolves fluids, unless the maintenance work is performed over an Impermeable surface in a dedicated maintenance area. Ploce a stock ile of s ill deanu moterials where it will be readil P P P Y accessible. AIl fueling irucks antl fueling oreas are required to hove spill kits and/or use other spill protection devices. Use adsorbent materials on small spills. Remove the absorbent materials prompUy and dispose o( properly. Insped onsite vehicles and equlpmenl daily at siartup (or leaks, and repair Immediotely. Keep vehides and equipment dean; do not allow excessive build—up of oil and grease. Segregate and recycle wastes, such as greases, used oil or oil filters, antifreeze, deaning solutions, automofive batteries, hydraulic ond transmission fluids. Provide secondary containment and covers (or these materials if stored onsite. Troin employees and subcontroctors in proper mointenonce 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 vehide or equipment is planned to be idle for mare than 1 h0uf. Properly dlspose of used oils, fluids, lubricants, and spill deanup moterials. Do not place used oil in a dumpster or pour into a storm drain or watercourse. Properly dispose of or recyde used batleries. Do noi bury used tires. Repair leaks of Ouids and oil immediately. Listed below is further information if you must perform vehide or equipment maintenance onsite. InsoecCion and Maintenance Inspect and verify lhat BMPs are 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. Keep ample supplies of spill deanup moteriols onsite. Mainlain waste fluld containers in leak proof condifion. Vehides and equlpmenl should be Inspected on each day of use. Leaks should be repaired immediotely 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. RELEA5E0 FOR CONSTRIICTI�N Su6jec��o compliance with allregula�ions of S�a�e antl Local Codes City of Carmel r �un��\i lo•rvalM.�� DATE: 06�� 7�20 VEHICLE AN� EQUIPMENT FUELING Descriotion and Pumose Vehlcle equipment fueling procedures and practices are designed to prevent fuel spills and leaks, and reduce or eliminate contaminailon of stormwatec This can be accomplished by using o(fsite facilities, fueling in designated areas only, endosing or covering stored fuel, implementing spill controls, and training employees and subconhactors in proper fueling procedures. Limitations Onsite vehlcle and equipmenl fueling should only be used where It is impractical to send vehides and equipment offsite for fueling. Sending vehicles and equipment offsile should be done in conjunction with a Stabillzed Construction Enirance� Exit. Imolementation 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 eliminaEing the need for a separate (ueling area at a site. Discourage °topping—off' of fuel tanks. Absorbent spill deanup 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 vehide and equipment fueling, unless the fuefmg Is performed over an impermeable sur(ace in a dedicated fueling area. Use absorbent materials on small spills. Do not hose tlown or bury the spill. Remove the adsorbent materiols promptly ond dispose of propedy. Avoid mobile (ueling of mobile construction equipment around the site; rather, transport the equipment to designated fueling areas. Train em lo ees and subcontractors in ro er fuelin and deanu P Y P P 9 P procedures. Dedicated fueling areas should be protected from stormwater runon and runoff, and should be localed at least 50 fl away from tlownstream drainage facilities and walercourses. Fueling must be performed on level—grade areas. Protect fueling areas with berms and dikes to prevent runoq runoff, and lo contain spills. Nozzles used in vehide and equipment fueling should be eqdipped with an automatic shutoif to control drips. Fueling operatians should not be left unattended. Federal, state, and local requlrements should be observed for any stationary above ground storage lanks. Insoection and Maintenance Vehlcles antl equipment should be inspected each day of use for leaks. Leaks should be repoired immediately or problem vehicles or equipment should be removed (rom the project site. Keep ample supplies of spill cleanup materials onsite. Immediately clean up spills and properly dispose of contaminated soil and cleanup materials. SOLID WASTE MANAGEMENT Description and Puroose Solid waste management procedures and practices are designed to prevent or reduce the dlscharge of pollutants to stormwater from solld or construclion wasle by providing designated waste collection areas and containers, arranging for regular disposal, and training employees and subcontraciors. Sultable Apolications This BMP is suitable for construction sites where the following wastes are qeneratetl or stored: Solid waste generated from trees and shrubs removed during land dearing, demolition of existing structures (rubble), and building construction Packaging materials including wood, paper, and plastic Scrap or surplus building materials induding scrap melals, rubber, plastic, glass pieces and masonry products Domestic wastes including food conlainers such as beverage cans, coffee cups, paper bags, plostic wrappers, and cigorettes Consiruction wastes 'mduding brick, mortar, timber, steel and metal scraps, pipe and electrical wttings, nonhamrdous equipment parts, styrofoam and other materials send transport and package construction materials Imolementafion The following steps will help keep a clean sile and reduce stormwater pollution: Select designated waste colleclion areas onsite. Inform trash—hauling contractors that you will accept only watertight dumpsters for onsite use. Inspect dumpsters for leaks and repair any dumpster that is not watertight. 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 wintly. Plan for addiYional 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 prompUy since erosion and sediment control devices tend to collect litter. Make sure that toxic liquid wastes (used oils, solvents, and paints) and chemicals (acids, pesticides, additives, curing compounds) are not tlisposed of in dumpsters designated for constructlon debris, Do not hose out dumpsters on the construction site. Leave dumpster deaning lo the trash hauling contractor. Arrange for regular wasie colleciion 6efore 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. CollecPion. Storage. and Disposal Littering on the project site should be prohibiled. To prevent dagging of the storm drainage system, lilter and debris removal from drainage grales, trosh rocks, and ditch lines should be a priority. Trash receptades shoultl be pravitled in the contractor's yard, fleld trailer areas, and at bcatlons where workers congregate for lunch ond break periods. Litter from work areas within the constructian limits of the project site should be collected and placed In waterfight 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. Dumpsters of sufficient size and number should be provided to mntain the solid waste generated by the projecl. Full dumpsters should be removed fram the project site and the conients should be disposed of by the trash hauling cantractor. ConsUuction debris and waste should be removed from lhe site blweekly or more frequently as needed. Construction material visible to the public should be stored or stacked in an orderly manner. Starmwater runon should be prevented from contacting stored solid waste thraugh the use of berms, dikes, or other temporary diversion shuctures or through the use of ineasures to elevate waste from site sur(aces. 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 ar ponding. Insoecfion and Maintenance Inspect and verify that activity—based BMPs are in place prior lo the commencemenl of associated activities. While acPivities associated with the BMP are under way, Inspect weekly to verify continued BMP implementation. A certified indlvidual approved by EHS lo conduct lhe weekly and after every z" rain event storm water BMP inspections. Inspect BMPs subject to non—stormwater discharge daily while non—stormwater discharges ocar Inspect construclion waste area regularly. Arrange for regular waste colleciion. DE—WATERING AND PUMPING OPERATIONS Descriplion and Purpose De—watering opewtions are practices that manage the discharge of pollutants when non—stormwater and accumulated precipitatian must be removed from a work bcation so that constructlon work may be accomplishetl. Suitable Applications These practices are Implemenied for discharges of non—storm water from canstruction sites. Non—stormwaters include, but are nol Ilmited lo, groundwater, water (rom cofferdams, water diversions, and waters used during construction activities that must be removed from a work area. Practices identified �m this section are also appropriate for implementation when managing the removal of accumulated precipilalion(stormwater) from depressed areas at a constructlon site. Limitations Sile conditions will dictate design and use of dewatering operatlons. The controls discussed in this best management practice (BMP) address sediment only. The controls detailetl in this BMP only allow for minlmal settling time for sediment parCicles. Use only when site conditions restrict the use o( the other control methods. Dewatering operations will require, and must comply with, applicable local permits. Imolementation De—walering discharges must not cause erosion at the discharge point A wriety of inethods can be used to treat water during de—watering operations. Several devices are presented below and provide oplions to achleve sediment removaL The size of particles present in the sediment and Permit or receiving water limitations on setliment are key consideratlons for selecting sediment treatmenl oplion(s); in some cases, lhe use o( multiple devices may be appropriate.

WHEN DEWATERMG BAG IS FULL OF SEDIMENT, REMOVE BAG AND DEPOSIT SEDIMENT IN A LOCATION DETERMMED BY THE ON—SITE ENGMEER. GRAVITY BAG FILTER Description: A gravity bag filter, also referred to as a dewatering bag, is a square or rectangular bag made of non—woven geotextile fabric that mllects sand, silt, and fines. Appropriate Applications: Effective for the removal of sedlments (gravel, sand, antl silt). Some metals are removetl with the sediment. Implementation: Water is pumped into one sitle of the bag ond seeps through the bottom and sides of the bag. A secondary barrier, such as a rock filter bed or straw/hay bale barrier, is placed beneath and beyond the edges of the bog to capture sedlments that escape the bag. Maintenance: Inspection of lhe flow conditions, bag condition, bag capacity, and the secondary barrier is required. Replace the bag when it no longer filters sediment or passes water ai a reasonable rate. The bag is disposed of offsite.
