816 Material handling and spill prevention plan:
Purpose:
The intention of this Spill Prevention, Control and Countermeasures (SPCC) is to establish the
procedures and equipment required to prevent the discharge of oil and hazardous substances in
quantities that violate applicable water quality standards, cause a sheen upon or discoloration of
the surface of navigable waters or adjoining shorelines, or cause sludge or emulsion to be
deposited beneath the surface of the water or adjoining shorelines. The Plan also establishes the
activities required to mitigate such discharges (i.e., countermeasures) should they occur.
Definitions:
Pollutant: means pollutant of any kind or in any form, including but not limited
to sediment, point, cleaning agents, concrete washout, pesticides, nutrients,
trash, hydraulic fluids, fuel, oil, petroleum, fuel oil, sludge, oil refuse, and oill mixed with wastes
other than dredged soil.
Discharge:
Includes but is not limited to, any spilling, leaking, pumping, pouring, emitting,
emptying, or dumping.
Navigable Waters:
Means all waters of the United States that are connected with a navigable stream,
lake, or sea. [Note: This definition is usually interpreted to mean any
wastewater (even normally dry wash or storm sewer) that eventually drains into a
navigable stream].
Plan Review and Amendements:
This Plan shall be reviewed and /or amended, if necessary, whenever there is a
change in the design of the site, construction, operation, or maintenance which
materially affects the site's potential for the discharge of regulated materiall.
Prediction of Potential Spills:
1. Nearest Navigable Water. JW Brendle Drain Elliot Creek
2. Drainage System: All storm drainage leaves the development site by through dosed storm
systems which eventually discharge into the JW Brendle Drain which flows southwesterly, or
Elliot Creek which flows southeasterly.
3. Possible Spill Sources (During and post construction): Vehicular sources such as
leaking fuel or oil, brake fluid, grease, antifreeze; construction trash and debris,
biological agents found in trash and debris, fertilizers, household items including
but not limited to cleaning agents, chemicals, paint, herbicides and pesticides.
4. Groundwater Contamination:
The facility maintains NO above ground or under ground storage tanks at this site.
Therefore, it is felt that there is little or no possibility of post construction
groundwater contamination. The facility does have city sanitary sewer and city water.
Alert Procedures for Spills:
1. Any personnel observing a spill will immediately instigate the following
procedure:
a.) Dialing "0" from any telephone.
b.) Notify the appropriate emergency personnel.
2. The Emergency Coordinator will then take the following actions:
a.) Barricade the area allowing no vehicles to enter or leave the
spill zone.
b.) Notify the Indiana Department of Environmental Management,
Office of Emergency Response by calling the appropriate
telephone number:
Office 317 233 -7745
Toll Free 800- 233 -7745
Also the National Response Center at 800 424 -8802
and provide the following information:
Time of observation of the spill
Location of the spill
Identity of material spilled
Probable source of the spill
Probable time of the spill
Volume of the spill and duration
Present and anticipated movement of the spill
Weather conditions
Personnel at the scene
Action initiated by personnel
c.) Notify the City of Carmel Fire Department Phone: 9 -1 -1
d.) Notify the City of Carmel Police Department Phone: 9 -1 -1
e.) Notify waste recovery contractor, maintenance personnel or other
contractual personnel as necessary for cleanup.
f.) Coordinate and monitor cleanup until the situation has been
stabilized and all spills have been eliminated.
g.) Cooperate with the IDEM -OER on procedures and reports involved
with the event.
Cleanup Parameters:
1. 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 clean -up operations. In addition, a continually updated list of
available absorbent materials and clean -up supplies should be kept on site.
2. 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 alterations to this plan.
3. When spills occur which could endanger human life and this becomes primary concern, the
discharge of the life saving protection function will be carried out by the local police
and fire departments.
4. 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.
5. Flushing of spilled material with water will not be permitted unless so authorized by the
Indiana Department of Environmental Management.
B14 Monitoring and maintenance guidelines for pollution prevention measures:

ADDITIONAL STORMWATER POLLUTION PREVENTION
MEASURES
VEHICLE Sc EQUIPMENT MAINTENANCE
Description and Purpose
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.
Suitable Applications
These procedures are suitable on all construction projects where an onsite yard area is
necessary for storage and maintenance of heavy equipment and vehicles.
Limitations
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 be done in conjunction with a Stabilized Construction Entrance /Exit. Outdoor
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).
Implementation
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
watercourses.
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 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 adsorbent 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.
Keep vehicles and equipment clean; do not allow excessive build -up 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 be placed under all vehicles and equipment placed on
docks, barges, or 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.
Do not place used oil in a dumpster or pour into a storm drain or watercourse.
Properly dispose of or recycle used batteries.
Do not bury used tires.
Repair leaks of fluids and oil immediately.
Listed below is further information if you must perform vehicle or equipment
maintenance onsite.
Inspection and Maintenance
Inspect and verify that 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 cleanup materials onsite.
Maintain waste fluid containers in leak proof condition.
Vehicles and equipment should be inspected on each day of use. Leaks should be repaired
immediately 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.
VEHICLE AND EQUIPMENT FUFI NG
Description and Purpose
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. These businesses are better equipped to
handle fuel and spills properly. Performing this work offsite can also be economical by
eliminating the need for a separate fueling area at a site.
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 o dedicated fueling area.
Use absorbent materials on small spills. Do not hose down or bury the spill. Remove the
adsorbent 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 if away from downstream drainage facilities and watercourses. Fueling
must be performed on level -grade areas.
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 ony stationary above ground
storage tanks.
Inspection and Maintenance
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 soil and cleanup
materials.
SCI ID WASTE MANAGEMENT
Description and Purpose
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.
Suitable Applications
This BMP is suitable for construction sites where the following wastes are generated or
stored:
Solid waste generated from trees and shrubs removed during land clearing, demolition of
existing structures (rubble), 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, nonhazardous equipment parts, styrofoam and other materials send
transport and package construction materials
Implementation
The following steps will help keep a clean site and reduce stormwater pollution:
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 odditional 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 (used oils, solvents, and paints) and chemicals (acids,
pesticides, additives, curing compounds) are not disposed of in dumpsters designated 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,
disposal areas.
Collection. Storage. and Disposal
Littering on the project site should be prohibited.
To prevent clogging of the storm drainage system, litter and debris removal from drainage
grates, trash rocks, and ditch lines should be o priority.
Trash receptacles should be provided in the contractor's yard, field trailer areas, and at
locations where workers congregate for lunch and break periods.
Litter from work areas within the construction limits of the project site should be collected
and laced in watertight 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 contain the solid waste
generated by the project.
Full dumpsters should be removed from the project site and the contents should be disposed
of by the trash hauling contractor.
Construction debris and waste should be removed from the site biweekly or more frequently
as needed.
Construction moteriol visible to the public should be stored or stocked in an orderly manner.
Stormwater ninon should be prevented from contacting stored solid waste through the use
of berms, dikes, or other temporary diversion structures or through the use of measures to
elevate waste from site surfaces.
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.
Inspection and Maintenance
Inspect and verify that activity -based 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.
Inspect BMPs subject to non stormwater discharge daily while non stormwater discharges
occur
Inspect construction waste area regularly.
Arrange for regular waste collection.
CONCREIL WASHOUT
The following steps will help reduce stormwater pollution from concrete wastes:
Discuss the concrete management techniques described in this BMP (such os handling of
concrete waste and washout) with the ready -mix concrete supplier before any deliveries are
made.
Incorporate requirements for concrete waste management into material supplier and
subcontractor agreements.
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 dumped onsite, except in designated areas.
For onsite washout:
Locate washout area at least 50 feet from storm drains, open ditches, or
water bodies.
Do not allow runoff from this area by constructing o 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.
DE\NATFRING AND PUMPING OPERATIONS
Description and Purpose
Dewatering operations are practices that manage the discharge
of pollutants when non- stormwater and accumulated precipitation
must be removed from a work location so that construction work
may be accomplished.
Suitable Applications
These practices are implemented for discharges of nonstormwater
from construction sites. Non stormwaters include, but are not
limited to, groundwater, water from cofferdams, water diversions,
and waters used during construction activities that must be
removed from a work area. Practices identified in this section
are also appropriate for implementation when managing the
removal of accumulated precipitation(stormwater) from depressed
areas at a construction site.
Limitations
Site conditions will dictate design and use of dewatering
operations. The controls discussed in this best management
practice (BMP) address sediment only. The controls detailed in
this BMP only allow for minimal settling time for sediment
particles. Use only when site conditions restrict the use of the
other control methods. Dewatering operations will require, and
must comply with, applicable local permits.
Implementation
and disposed
of only at authorized
Dewatering discharges must not cause erosion at the discharge
point. A variety of methods can be used to treat water during
dewatering operations. Several devices are presented below and
provide options to achieve sediment removal. The size of
particles present in the sediment and Permit or receiving water
limitations on sediment are key considerations for selecting
sediment treatment option(s); in some cases, the use of multiple
devices may be appropriate.
Sediment Basin
Uescrtp tion:
A sediment basin is a temporary basin with a controlled release
structure that is formed by excavation or construction of an
embankment to detain sediment -laden runoff and allow sediment to
settle out before discharging. Sediment basins are generally larger than
Sediment Traps.
Appropriate Applications:
Effective for the removal of gravel, sand, silt, some metals that settle
out with the sediment, and trash.
Irnplemen totlon:
Excavation and construction of related facilities is required.
Temporary sediment basins must be fenced if safety is a concern.
Outlet protection is required to prevent erosion at the outfall location.
l✓ G r7 tenanc
Maintenance is required for safety fencing, vegetation, embankment, inlet
nd outfall structures, as well as other features.
Removal of sediment is required when the storage volume is educed by
one -half.
Sediment Trap
i)escr!p t
A sediment trap is a temporary basin formed by excavation and /or
construction of an earthen embankment across a waterway or low
drainage area to detain sediment -laden runoff and allow sediment to
settle out before discharging. Sediment traps are generally smaller than
Sediment Basins.
Apprcpriate Applications:
Effective for the removal of large and medium sized particles (sand and
gravel) and some metals that settle out with the sediment.
Implementation:
Excavation and construction of related facilities is required.
Trap inlets should be located to maximize the travel distance to the
trap outlet.
Use rock or vegetation to protect the trap outlets against erosion.
Maintenance:
Maintenance is required for vegetation, embankment, inlet and outfall
structures, as well as other features.
Removal of sediment is required when the storage volume is reduced by
one third.
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 collects sand,
silt, and fines.
Appropriate Applications:
Effective for the removal of sediments (gravel, sand, and silt). Some
metals are removed with the sediment.
lmplernen to ticn:
Water is pumped into one side of the bag and 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 bag to capture
sediments that escape the bag.
Maintenance:
tenance:
Inspection of the flow conditions, bag condition, bag capacity, and the
secondary barrier is required.
Replace the bag when it no longer filters sediment or passes water at a
reasonable rate.The bag is disposed of offsite.
