(See Sheet _6_ of _9)
13. In order to minimize the release of potential pollutants during construction the Contractor shall
implement this material handling and spill prevention plan. The Contractor shall review this plan
with all subcontractors and require that they implement the plan as well.
1. Construction Equipment
A. Fueling, lubricating, and fluids: All operations involving the addition of fluids to
equipment should be done in one location, as designated on Sheet 6 of 9, so
that spills are limited to one location on the site, which will facilitate the
cleanup of spills. If an onsite fueling tank is planned to be on site, it shall be
double walled and stored in this designated area. This location is an area that
will not allow spilled fuilds to migrate into subsurface soils. In the event of a
spill, the fluids shall immediately be cleaned up by removing the contaminated
soil or stone shich shall be disposed of in an acceptable manner. Spills on
hard surfaces shall be soaked up by an acceptable material such as Oil Dry
and the absorbent material disposed of in a proper manner. The soil shall also
be reported immediately to the Contactor's superintendent.
B. Equipment repair, especially when fluids must be removed from the equipment
or the possibility of fluid spills is high, should always be done offsite at a facility
that is more suitable than a construction site to handle spills. When equipment
must be repaired onsite it should be moved to the maintenance and fueling are
a if possible. Otherwise, suitable on site containers should be placed under the
equipment during repair to catch any spilled fluids and these fluids should be
disposed of in a proper manner.
C. All reuseable fluids containers, such as gasoline cans, shall be inspected for leaks
each time thay are used. If leaks are found, the fluid shall be removed from the
container in a proper manner and the container disposed of in an acceptable manner.
Empty disposable containers, such as grease tubes and lubricanting oil and brake
fluid containers, and their packaging, shall be disposed of in a proper manner and
shall not be left on the ground or in the open on the construction site.
2. Construction Materials and their Packaging
A. Erosion control measures shown on these plans shall be implemented prior to and
during constrution in the proper sequencing to minimize soil erosion. Erosion controle
shall be imspected and maintained as described elsewhere in these plans. Excessive
dusting of soil on the site shall be minimized by reducing construction traffic across
bare soil during dry and /or windy weather, and by applying water or other acceptable
dust control measures to the soil. Upon completion of sonstruction and suitable
establishment of permanent vegetation, temporary erosion control measures such as
silt fence, sheck dams and inlet protection devices shall be removed in a manner
to minimize additional land disturbance. Any areas disturbed by these operations
shall be properly revegetated.
B. Large waste materials created by cutting, sawing, drilling, or other operations shall
be properly disposed of in suitable onsite waste containers. The site shall be checked
at the end of the day, as a minimum, and all waste materials, including those blown
across or off the site by wind, shall be picked up and disposed of in suitable
containers. Where possible, operations such as sawing, that create small particles
should be performed in one spot in an area protected from wind, and waste particles
collected and sidposed of frequently to minimize wind disposal. Packaging used to
transport materials to the site for construction of the facility shall be disposed of
properly, whether the material is taken out of its package and incorporated into
the project immediately or stored onsite for future use. Packaged materials stored
onsite shall be inspected regularly and any loose packaging shall be repaired or
disposed of properly.
C. All dewatering ofactivities shall be done in accordance to good erosion control
practices. These practices should include the use of dirt bags such as Dandy Dirt
Bages. The use of these types of dewatering devices will remove large quantities of
sediment and dirt and prevent these materials to enter the storm sewer system.
D. If the use of lime is used to stablize the soil of the site then all construction
equipment used shall be cleaned oof all excess materials with water in the maintenance
and refuiling area as shown within these plans.
E. Nutrients and fertilizers shall only be used to establish rapid vegitation. When these
producets are utilized, the user should pay attention to the products recommended usage.
3. Concrete Waste Water
A. All concrete waste water shall be disposed of in the designated area as shown on this
sheet. This area is a 4' high, 10' diameter doughnut type mulch berm which shall be
constructed over a geotextile fabric. This area shall be inspected on a daily basis as a
minimum. When this area becomes full, the pollutants shall be excavated, placed in an
acceptable container and disposed of in a proper manner.
4. Paint Products
A. All excess paint and there related products shall be disposed of in the manner at which
the manufacturer suggests. Under NO circumstnaces will point or their related products
be cleaned or disposed of in soil, sanitary sewers, storm sewers or detention basins. Any
violation of this shall be reported to the job superintendent.
In the event of accidental contamination all efforts should be made to remove
contaminants in an appropriate manner. The Carmel Fire Department (317 -571 -2600)
should be contacted immediately to determine if further measures are needed.
14. Person in charge of and knowledgeable about erosion and sediment control shall inspect the
site for stormwater pollution prevention deficiencies at least weekly and again within 24 hours
of every 3 inch rain event. Construction Entrance shall be repaired if it is not performing
properly. Silt fence shall be repaired /replaced in the event that it has foiled. Drop Inlet
Protection Basket shall be repaired/ replaced if foiled sediment removed. Curb Inlet
Protection shall be repaired /replaced if foiled sediment removed. Sediment Traps shall
be cleaned out if they are over 50% full of sediment.
15. There is only one lot in this project. No special specification are required.
PLAN ELEMENT INDEX
Section C
Proposed site will be a commercial development. Potential pollutants from this
type of development include, but are not limited to: fluids and debris from parked
vehicles vehicular traffic which could include: fossil fuels, oil, grease,
antifreeze, brake fluid, window washer fluid, rubber, plastic, metal fragments,
grit (sediment) from wearing of the road surface, 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 runoff contact with impervious surfaces.
2. The existing stormwater quality measures will remain in place until no erosion
or siltation con take place.
3. The post construction measures used to minimize sedimentation in waterways
include inlet sediment baskets and detention pond. The detention pond has been
designed with aquatic plant material. The inlet sediment baskets in conjunction with
the aquatic plant material will collect runoff from the pavement and filter it. The
design of the inlet sediment baskets will allow sediment to be partially infiltrated
before storm water enters the designed storm sewer system. Storm Grates will
prevent large items from entering the storm pipes and leaving the site. The
detention basin, and aquatic plant material, which is designed to have water in it
at all times, will also help reduce sediment and trash by allowing it to drop out
prior to leaving the site.
4. Catch basins, and pond locations are provided on the drainage plan. Details are
provided on the Detail sheets.
311
5. Maintenance of all Stormwater pollution prevention measures will be the responsibility
of the property owner, Tom Wood Management, Inc., utilizing procedures outlined in
the 0 M manual for Post Construction water quality measures, The maintenance
guidelines consist mostly of good housekeeping measures. Any grassed areas or
vegetated areas that experience erosion from rainfall events should be repaired as
soon as possible. Trash or litter should be picked up and properly disposed to prevent
it from getting into the storm drainage system and downstream waterways.
Erosion of the detention pond banks should be addressed as soon as it
becomes visible by filling the eroded area with suitable soil and establishing
vegetation immediately, perferably by sodding, or seeding and mulching and
monitoring until suitable vegetation is established. The some measure should be used
for steep banls of any earth berm or any other steep area. The detention pond
should also be monitored for sediment coming from the storm sewer system. If the
bottom of the pond receives sediment, indicated by the sediment markers, it
should be cleaned out and the source found and repaired. The elveation of the
pond bottom should be checked every 8 to 10 years and, if significant sediment
is encountered, it should be removed from the basin. This should be done during
periods of low rainfall to allow soil stirred up by excavation to settle out before a
rain event. The detention pond outlet should be protected by adequate filtration
(rip -rap, shown on these plans) to prevent soil from entering the offsite storm
drainage system.
Pavement areas should also be monitored for pollutants. Any large quantity of fluids
such as oil, antifreeze, brake fluid, etc. found on the pavement should be reported to
the owner and the source determined, if possible, and removed from the site for
mointentance or repair. Pavement should also be monitored for sediment coming from
vegitated areas that drain onto the pavement. If sediment is found it should be
cleaned off the pavement, and the source of the soil found and repaired as
discussed above.
