B14 & B15 - MATERIAL HANDLING AND SPILL PREVENTION AND SPILL RESPONSE PLAN MEETING THE
REQUIREMENTS IN 327 IAC 2-6.1:
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 made 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 spills 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.
Potential pollutants sources relative to a construction site may include, but are not limited to
material and fuel storage areas, fueling locations, exposed soils and leaking
vehicle/equipment. Potential pollutants that may appear at the site due to construction
activities include, but are not limited to diesel fuel, gasoline, concrete and concrete washout,
solid waste, sediment, paint and solvents, equipment repair products, anti-freeze and
fertilizer. No Non-stormwater discharge sources were identified for this project site.
In order to contain potential pollutants several construction stage measures will be
implemented. This includes a stable construction entrance, paved area inlet protection on
and adjacent to the site, perimeter silt fencing, and temporary stabilization as necessary.
A stone construction entrance will be located at the east of the site. See Sheet C103 for plan
location and Sheet C104 for details and specifications.
Seeding will be used as temporary surface stabilization measures as well as Permanent
surface stabilization measures. The location of each surface stabilization measure are on
sheet C103. The details and specifications for each stated measure are on sheet C104.
install temporary seeding after a specific stage of construction has been completed
(temporary or final) where areas will be idle of construction activities for a period of 15 days
or more.
Temporary seeding will be used as erosion control measures for concentrated flows. The
location of each measure is located on sheet C103. The details and specifications for each
stated sediment control measure is on sheet C104.
Silt Fencing will be installed along the perimeter of the site The location of each measure
are on sheet C103. The details and specifications for each stated measure are on sheet
C104.
N/A
The stormwater outlet protection is provided at the end sections draining into the dry
detention pond.
Grade stabilization will be installed on all slopes 3:1 or greater. The location of each
measure are on sheet C103. The details and specifications for each stated measure are on
sheet C104.
Dewatering is not anticipated. Should the water table temporarily inhibit excavation
measures, the water shall be pumped upstream above proposed silt fence to allow for
sediment filtration as specified on C103.
N/A
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. temporary
sediment trap maintenance requirements
1.inspect temporary sediment traps after each storm event and immediately repair any
erosion and piping holes.
2.remove sediment when it has accumulated to one-half the design depth.
3.replace spillway gravel facing if clogged.
4.inspect vegetation, and re-seed if necessary.
5.check the spillway depth periodically to ensure a minimum of 1.5 ft. depth from the
lowest point of the settled embankment to highest point of the spillway crest, and fill
any low areas to maintain design elevation.
6.promptly replace any displaced riprap, being careful that no stones in the spillway are
above design grade.
7.after all disturbed areas have been stabilized, remove the structure and sediment,
smooth the site to blend with adjoining areas, and stabilize.
The final land use for the site will be an apartment complex. Potential pollutant sources that may appear at the
site due to proposed land use activities, but are not limited to vehicles, exposed soil and trash. Potential
pollutants include, but are not limited to oil, grease, antifreeze, brake fluid, brake dust, rubber fragments,
gasoline, diesel fuel and other hydrocarbons, metals from vehicular and other sources, grit (sediment) from
wearing of the road surface and falling or washing off of vehicles, 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 run-off contact with impervious surfaces.
The use of one mechanical water quality structure (Aqua-Swirl XC-4) and an existing detention pond with new
native plantings along the banks will provide the stormwater quality requirements. The location of stormwater
quality measures are on sheet C103. The stormwater quality specifications are provided on sheets C801.
All details of the proposed stormwater infrastructure found on C102 and C103 should be referenced on C801.
The existing dry detention pond will be regraded to increase its storage capcity and an Aqua-Siwrl XC-4 will be
placed on top of an existing storm sewer. Underground roofdrains will be around the building addition to collect
the new roof drainage and direct it to an existing on-site storm sewer. After final landscaping and seeding and
the completion of all construction activities, it is the responsibility of the Contractor/Responsible entity to remove
any trash or sedimentation from the swale and detention basin. See Maintenance guidelines for
post-construction stormwater measures below.
An Operations & Maintenance Manual has been prepared for this site. The Owner is responsible for
implementing and reporting the post-construction water quality measures as outlined in the O&M Manual.
Any debris in the parking areas should be picked up and placed in the trash receptacle. The parking area shall
be kept clean and be swept every 3 months.
Storm Sewer System
Inspect the system every six months. Evaluate the condition of the system and confirm no riprap failures, storm
drains are in good condition with no evidence of non-stormwater discharges or excessive sedimentation, inlet
and outlet structures are in good repair with no cracks or excessive sediments in the structures, castings well
seated and orifice openings free of obstructions. Inspect and clean the system once annually. Call a local
company to remove sediments, oil, and other floatable pollutants as required. Dispose of all waste in
accordance with federal, state and local requirements. Water and sediment from cleaning procedures should
NOT be dumped into a sanitary sewer.
Dry Detention Basin
Inspect the existing dry detention pond every six months and clean the system as needed. Keep the banks
free of debris and trash. Keep the pipe ends and end sections free of debris and trash. Once a year, inspect
the bottom of the dry pond to make sure sediment acculation has not exceeded 6 inches. Whenever sediment
acculation exceeds 6 inches, have the dry pond dredged / cleaned out back to the original grade. Dispose of
all waste in accordance with federal, state and local requirements. Water and sediment from cleaning
procedures should NOT be dumped into a sanitary sewer.
Aqua-Swirl
Inspect the Aqua-Swirl every six months and clean the system as needed. Inspect and clean the system once
annually regardless of whether it has reached its sediment or floatable pollutant storage capacity. Call a local
vactor company to remove sediments, oil, and other floatable pollutants with a vactor. Dispose of all waste in
accordance with federal, state and local requirements. Water and sediment from cleaning procedures should
NOT be dumped into a sanitary sewer.

B14 & B15 - Cont.
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 an 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 bags 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 Indianapolis Fire Department
(317-327-3811) and IDEM Spill Response Center (888-233-7745) shall be contacted in the case of a material
spill occurring.
