(613) MATERIAL HANDLING AND SPILL PREVENTION
Expected materials that may appear at the site due to construction activities include, but are not limited to petroleum products, fertilizers,
paint and solvents, and concrete. Materials shall be stored in the designated material storage area.
Spill prevention for vehicle and equipment fueling shall conform to the following practices: vehicle equipment fueling procedures and
practices are designed to prevent fuel spills and leaks, and reduce or eliminate contamination of stormwater. This can be accomplished by
using offsite facilities, fueling in designated areas only, enclosing or covering stored fuel, implementing spill controls, and training employees
and subcontractors in proper fueling procedures. Limitations: Onsite vehicle and equipment fueling should only be used where it is impractical
to send vehicles and equipment offsite for fueling. Sending vehicles and equipment offsite should be done in conjunction with a Stabilized
Construction Entrance/Exit. Implementation: Use offsite fueling stations as much as possible. Discourage "topping -off" of fuel tanks.
Absorbent spill cleanup 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 vehicle and equipment fueling, unless the fueling is performed over an
impermeable surface in a dedicated fueling area. Use absorbent materials on small spills. Do not hose down or bury the spill. Remove the
absorbent materials promptly and dispose of properly. Avoid mobile fueling of mobile construction equipment around the site; rather,
transport the equipment to designated fueling areas. Train employees and subcontractors in proper fueling and cleanup procedures. Dedicated
fueling areas should be protected from stormwater runon and runoff, and should be located at least 50 ft away from downstream drainage
facilities and watercourses. Fueling must be performed on level -grade area. Protect fueling areas with berms and dikes to prevent runon,
runoff, and to contain spills. Nozzles used in vehicle and equipment fueling should be equipped with an automatic shutoff to control drips.
Fueling operations should not be left unattended. Federal, state, and local requirements should be observed for any stationary above ground
storage tanks.
Vehicles and equipment should be inspected each day of use for leaks. Leaks should be repaired immediately or problem vehicles or
equipment should be removed from the project site. Keep ample supplies of spill cleanup materials onsite. Immediately clean up spills and
properly dispose of contaminated soils.
Spill prevention for solid waste shall conform to the following practices: Solid waste management procedures and practices are designed
to prevent or reduce the discharge of pollutants to stormwater from solid or construction waste by providing designated waste collection areas
and containers, arranging for regular disposal, and training employees and subcontractors. Solid waste generated from trees and shrubs
removed during land clearing, demolition of existing structures, and building construction. Packaging materials including wood, paper, and
plastic. Scrap or surplus building materials including scrap metals, rubber, plastic, glass pieces and masonry products. Domestic wastes
including food containers such as beverage cans, coffee cups, paper bags, plastic wrappers, and cigarettes. Construction wastes including
brick, mortar, timber, steel and metal scraps, pipe and electrical cuttings, non hazardous equipment parts, Styrofoam and other package
construction materials. Select designated waste collection 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 windy. Plan for
additional 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 promptly since erosion and sediment control devices tend to collect litter. Make sure that
toxic liquid wastes (sued oils, solvents and paints) and chemicals (acids, pesticides, additives, curing compounds) are not disposed of in
dumpsters designed for construction debris. Do not hose out dumpsters on the construction site. Leave dumpster cleaning to the trash
hauling contractor. Arrange for regular waste collection before 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. 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 or ponding. Inspect construction
waste area regularly. Arrange for regular waste collection.
Spill prevention for concrete washout shall conform to the following practices: Store dry and wet materials under cover, away from
drainage areas. Avoid mixing excess amounts of fresh concrete. Perform washout of concrete trucks offsite or in designated areas only. Do
not wash out concrete trucks into storm drains, open ditches, streets, or streams. Do not allow excess concrete to be duped onsite, except
in designated areas. Locate washout areas at least 50 ft from storm drains, open ditches, or water bodies. Do not allow runoff from this
area by constructing a temporary pit or bermed area large enough for liquid and solid waste. Wash out wastes into the temporary pit where
the concrete can set, be broken up, and then disposed properly. Avoid creating runoff by draining water to a bermed or level area when
washing concrete to remove fine particles and expose the aggregate. Do not wash sweepings from exposed aggregate concrete into the
street or storm drain. Collect and return sweepings to aggregate base stockpile or dispose in the trash.
The cleanup parameters shall conform to the following practices: The developer homeowners association shall be continually kept
informed, maintain lists of qualified contractors and available Vac trucks, tank pumpers and other equipment readily accessible for cleanup
operations. In addition, a continually updated list of available absorbent materials and cleanup supplies should be kept on site. All
maintenance personnel will be mode 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
alteration to this plan. When spies occur which could endanger human life and this become primary concern, the discharge of the life saving
protection function will be carried out by the local police and fire departments. 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. Flushing of
spilled material with water will not be permitted unless so authorized by the Indiana Department of Environmental Management.
Spill prevention for vehicle and equipment maintenance shall conform to the following practices: Prevent or reduce the contamination of
stormwater resulting from vehicle and equipment maintenance by running a "dry and clean site The best option would be to perform
maintenance activities at an offsite facility. If this option is not available then work should be performed in designated areas only, while
providing cover for materials stored outside, checking for leaks and spills, and containing and cleaning up spills immediately. These procedures
are suitable on all construction projects where on onsite yard area is necessary for storage and maintenance of heavy equipment and vehicles.
Onsite vehicle and equipment maintenance should only be used where it is impractical to send vehicles and equipment offsite for maintenance
and repair. Sending vehicles equipment offsite should by done in conjunction with a stabilized construction entrance exit. Out door
vehicle 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). If
maintenance must occur onsite, use designated areas, located away from drainage courses. Dedicated maintenance areas should be protected
from stormwater runon and runoff, and should be located at least 50 ft from downstream drainage facilities and water courses. Drip pans or
absorbent pads should be used during vehicle and equipment maintenance work that involves fluids, unless the maintenance work is performed
over and impermeable surface in a dedicated maintenance area. Place a stockpile of spill cleanup materials where it will be readily accessible.
All fueling trucks and fueling areas are required to have spill kits and /or use other spill protection devices. Use absorbent materials on small
spills. Remove the absorbent materials promptly and dispose of properly. Inspect onsite vehicles and equipment daily at startup for leaks,
and repair immediately. Deep vehicles and equipment clean; do not allow excessive buildup of oil and grease. Segregate and recycle wastes,
such as greases, used oil or oil filters, antifreeze, cleaning solutions, automotive batteries, hydraulic and transmission fluids. Provide
secondary containment and covers for these materials if stored onsite. Train employees and subcontractors in proper maintenance and spill
cleanup procedures. Drip pans or plastic sheeting should by placed under all vehicles and equipment placed on docks, barges, other
structures over water bodies when the vehicle or equipment is planned to be idle for more than 1 hour. Properly dispose of used oils, fluids,
lubricants, and spill cleanup materials. Properly dispose of or recycle used batteries. Do not place used oil in a dumpster or pour into a
storm drain or water course. Properly dispose of used oils, fluids, lubricants, and spill cleanup materials. Don not bury tires. Repair leaks
of fluids and oil immediately.
Spill prevention for fertilizers shall conform to the following practices: Fertilizer's used will be applied only in the minimum amounts
recommended by the manufacturer. Once applied, fertilizer will be worked into the soil to limit exposure to storm water. The contents of any
partially used bogs of fertilizer will be transferred to a sealable plastic bin to avoid spills.
Spill prevention for paint and solvents shall conform to the following practices: All containers will be tightly sealed and stored when not
required for use. EXCESS PAINT WILL NOT BE DISCHARGED TO THE STORM SEWER SYSTEM but will be properly disposed of according to
manufacturers' instructions or State or local regulations.
Spill prevention and cleanup shall conform to IDEM form 327 IAC 2 -6 and the Carmel Fire Department shall be contacted in the case of
a material spill occurring
