Drop Inlet Protection Basket
It is the intent of this device to detain water for the purpose of allowing suspended solids
in the water to settle out before the water enters the storm structure. Some filtering will
occur as water passes through the device.
The bottom of this device is to seal against the flat outer part of the casting. The overall
dimension of the basket shall be no smaller than the water inlet perforations in the casting
and no larger than the outer dimensions of the casting. The height shall be 15"
The basket frame shall be welded wire mesh rolled or bent and welded to itself to fit the
casting. The wire size shall be no smaller than .149" dia. and openings no larger than 18
sq in. It is important that the bottom of the wire frame be smooth so as not to allow any
leakage between the basket and casting. The top of the basket shall be open to prevent
flooding during heavy storm events.
Fabric shall be woven polypropylene allowing 15- 25gaUmin /sq in. If non -woven fabric
is used, the maintenance intervals should be increased to replace silt laden fabric. The

B13. Material Handling and Spill Prevention Plan:
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, lubrication and fluids: All operations involving the addition of fluids
to equipment should be done in one location, as designated on Sheets
C300 -C301, 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 fluids to migrate into subsurface soils. In the
event of a spill, the fluid shall immediately be cleaned up by removing the
contaminated soil or stone which 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 spill shall
also be reported immediately to the Contractor'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 area 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 reusable fluid containers, such as gasoline cans, shall be inspected for
leaks each time they 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
lubricating 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.

B13 cont. 2. Construction Materials and their Packaging
a. Erosion control measures shown on these plans shall be implemented prior to
and during construction in the proper sequencing to minimize soil erosion.
Erosion controls shall be inspected 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 construction and suitable establishment of permanent
vegetation, temporary erosion control measures such as silt fence, check 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 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 disposed of frequently to minimize wind dispersal.
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 of activities shall be done in accordance to good erosion control
practices. These practices should include the use of dirt bags such as Dandy Dirt
Bags. The use of these types of dewatering devices will remove large quantities
of silt, sediment and dirt and prevent these materials to enter the storm sewer
system.
d. If the use of lime is used to stabilize the soil of the site then all construction
equipment used shall be cleaned of all excess material with water in the
maintenance and refueling area as shown within these plans.
e. Nutrients and fertilizers shall only be used to establish rapid vegetation. When
these products are utilized, the user should pay strict attention to the products
recommended usage.
3. Concrete Waste Water
a. All concrete waster water shall be disposed of in the designated area as shown on
Sheets C300 -C301. This area is a 2' 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 suggest. Under NO circumstances will paint 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 spills that are easily cleaned up with rags and absorbent materials,
please contact the Construction Supervisor.
In the event of spills that require removal of soils or other materials, please contact
the Construction Supervisor, Developer and the Local Fire 1 ;4.; tment.
In the event of spills that have potential groundwater or surface water contamination
or have already done so, please contact the Construction Supervisor, Developer, Local Fire
Station and IDEM.
B14. Monitoring and Maintenance Guidelines for Each Proposed Pollution
Prevention Mea sure: Person in charge of and knowledgeable about erosion and sediment
control shall inspect the site for stormwater pollution prevention deficiencies at least
daily and again within 24 hours of every 1/2 inch rain event.
See Erosion Crontrol Notes on this sheet for specifications.
B15. Erosion and Sediment Control Specifications For Individual Building
Lots: Construction sequence for individual building lots is shown on this sheet.
Stormwater Pollution Prevention Plan
Post Construction Component
Cl. Description of Pollutants and Their Sources Associated with the Proposed
Land Use: Proposed site will be an amenity area for an existing subdivision. 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, chlorine
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.
C2. &C3. Sequence Describing Stormwater Quality Measure Implementation:
Description of Proposed Post Construction Stormwater Quality Measures:
The post construction measures used to minimize sedimentation in waterways include
swales and detention ponds. The design of the swales will allow sediment to be partially
infiltrated before storm water enters the designed storm sewer system. Beehive inlets will
prevent large items from entering the storm pipes and leaving the site. The detentions
basins 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.
C4. Location, Dimensions, Specifications and Construction Details of Each
Stormwater Quality Measures:
Catch basins, swales, and lake locations are provided on the site development plans.
Details are provided on the Construction Plan Detail sheets.
C5. Description of Maintenance Guidelines for Proposed Post Construction
Water Quality Measures:
Maintenance of all Stormwater pollution prevention measures will be the responsibility of
the project owner, Platinum Properties until a point in time in which the Home Owners
Association is established. At that point said association shall assume all maintenance
responsibilities. The maintenance guidelines consist mostly of good housekeeping
measures. Any grassed or vegetated areas that experience erosion from rainfall events
should be repaired and revegetated 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,
preferably by sodding, or by seeding and mulching and monitoring until suitable
vegetation is established. The same measure should be used for steep banks of any earth
berm or any other steep area. The detention pond should also be monitored for sediment
coming from the storm drainage 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 elevation 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 also 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 Home
Owner Association and the source determined, if possible, and removed from the site for
maintenance or repair. Pavements should also be monitored for sediment coming from
vegetated 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.

streams and drainage ways on uplands. Permeability is moderate In the subsoil and moderately slow in the substratum. This soil
is suitable for urban development. The main soil features that adversely affect the engineering uses of this soil are moderate
potential frost action, moderate shrink -swell potential, and moderately slow permeability. The hazard of erosion is high during
construction.

Fox loan, 8 to 18 9. slopes, severely eroded- This moderate sloping, so s side slopes adjacent g ys
on terraces and in domelike areas on uplands. It is moderately deep over sand and gravelly sand. Permeability is moderate in
the subsoil and rapid in the underlying material. Available water capacity Is low. This soil has moderate limitations for urban
development (Slope). Features that adversely affect engineering uses of this soil are moderate frost action. moderate shrink -swell
potential, moderate permeability in the subsoil and very rapid permeability in the under lying material. Topsoil should be stockpiled
for use in exposed areas.
We Westland silty clay loom This nearly level, deep, very poorly drained not is In depressions, swales, and narrow drainogeways on
outwash plains. Runoff from higher adjacent soils is ponded on this soil. Permeability is slow. The water table is commonly at
the surface or Is at o depth of less than one foot in winter and early spring. Availbale water capacity is high. Surface runoff Is
ponded or is very slow. The main sot features that adversely affect engineering uses of this soil ore a seasonal high water table,
high potential frost action, moderate shrink -swell potential, and slow permeability. The base material for roads needs to be
replaces or strengthened with suitable material.
OcA Ockley silt loom, 0 -2 5 slopes- This nearly level, deep well drained soil is mainly on brood terraces. Permeability and available
water capacity is moderate. This soil is suitable for urban development. Features that adversely affect engineering uses of this
sot are moderate frost action. moderate shrink -swell potential, moderate permeability in the subsoil and very rapid permeability in
the under lying material.
OcB2 Ockley silt loam, 2 -6 R dope, eroded- This gently sloping, deep well drained soil Is mainly on brood terraces. Permeability and
available water capacity is moderate. This soil Is suitable for urban development. Features that adversely affect engineering uses
of this soil are moderate froet action, moderate shrink -swell potential, moderate permeability in the subsoil and very rapid
permeability in the under lying material. This soil has severe limitations for local roads because of low strength. The base material
of roads needs to be strengthened with suitable material.

2. At a position downslope of the lot and upslope
of the inlet, lay bags tightly in a row curving
upslope from curb and away from inlet.
3. Overlap bags onto the curb and extend a min-
imum of 3 feet into the street.
4. For additional layers, overlap bags with the
row beneath, and leave a one -bag gap in the
middle of the top row to serve as a spillway.
5. Place bags in an arc around curb inlets that
are in a sump position.
6. Set up safety /traffic barriers to keep vehicles
from hitting bags, causing possible injury.
7. Inspect and repair as needed, and remove any
accumulated sediments after every storm.
