Cleanup Parameters:
1. The Developer/Contractor shall be continually kept informed and 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.
Monitoring and maintenance guidelines for pollution prevention measures:
Coln Fiber Log Beck Dams
Requirements:
1. Material: As specified on plans or approved equal.
2. Anchoring: Use 2" x 2" woods stakes with pre -installed groove to anchor rape binding.
3. Rope binding shall be per manufacturer's recommendations.
Installation:
1. Grade the site as specified in the construction plans.
2. Add topsoil where appropriate.
3. Cut in groove to receive coir fiber log.
4. Place log in groove with bottom set a minimum of 4 inches below finish grade.
5. Make sure log length is enough that both ends of log extend up slope to a point above normal
flow elevation.
6. Install anchor stakes a maximum of 4 ft. on center on both sides of log.
7. Install rope lashing from stake to stake per manufacturers recommendations.
8. Prepare the seedbed, fertilize (and lime, if needed), and seed the area immediately after grading.
Maintenance:
1. During vegetative establishment, inspect weekly and after significant storm events of 0.5" or more.
2. Inspect periodically for deterioration or damage from construction activities and repair immediately.
3. After the contributing drainage area has been stabilized, remove all straw bales and sediment
deposits, bring the disturbed area to grade and stabilize it.
Silt Fence (Sediment Fence)
Requirements:
Drainage area: Limited watershed area to 1/4 acre per 100 ft. of fence; further restricted by
slope steepness
Location: Fence nearly level, approximately following the land contour, and at least 10 ft. from
toe of slope to provide a broad, shallow sediment pool.
Installation Requirements:
1. Trench: 8 in. minimum depth, Flat -bottom or V-shaped, filled with compacted soil or gravel
to bury lower portion of support wire and/or fence fabric.
2. Support posts: 1 1/4" x 1 1/4". hardwood posts (if used) or steel fence posts set at
least 1 ft. deep. (Steel posts should have projections for fastening fabric.)
3. Spacing of posts: 8 ft. maximum if fence supported by wire, 6 ft. for extra -strength
fabric without wire backing.
4. Fence height: High enough so depth of impounded water does not exceed 1 1/2 ft. at any
point along fence line.
5. Support wire (optional): 14 gauge, 6-in. mesh wire fence (needed if using
standard -strength fabric).
Fence fabric: Woven or non -woven geotextile fabric with specified filtering efficiency and
tensile strength and containing UV inhibitors and stabilizers to ensure 6-mo. Minimum life
at temperatures 0- 120T.
Maintenance:
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.
Erosion Gmtrd Blanket
Requirements:
Material: As specified on plans or approved equal.
Anchoring: Per manufacturer's recommendations for intended use or per plan specifications.
Installation:
1. Select the type and weight of erosion control blanket as directed on plans.
2. Grade the site as specified in the construction plans.
3. Add topsoil where appropriate.
4. Prepare the seedbed, fertilize (and lime, if needed), and seed the area immediately after
grading.
5. Following manufacturers directions, lay the blankets on the seeded area such that they
are in continuous contact with the soil and that the upslope or upstream ones overlap
the lower ones by at least 8 in.
6. Tuck the uppermost edge of the upper blankets into a check slot (slit trench), backfll
with soil, and tamp down.
7. Anchor the blankets as specified by the manufacturer or as specified in the plans.
Maintenance:
1. During vegetative establishment, inspect after each storm event for any erosion below the
blanket.
2. If any area(s) shows erosion, pull back that portion of the blanket covering it, re -seed
the area and relay and staple the blanket.
3. After vegetative establishment check the treated area periodically.
Temporary Canstruciion Entrance/Exit Pad
Requirements:
1. The construction entrance shall be located off of the existing parking lot as shown on the
plans. If muddy conditions result in tracking on Road, clean up immediately and add "wheel
wash area."
2. Material for Gravel Construction entrance and/or Wheel Wash Area: 2-3 in. washed stone
(INDICT CA No. 2) over a stable foundation. Thickness: 8 in. minimum
3. Width: 30 ft. minimum or full width of entrance/exit roadway, whichever is greater.
4. Length: 150 ft. or as the site will accommodate minimum. The length can be shorter for
small sites.
5. Washing Facility Level area with 3 in. washed stone minimum or a commercial rack, and
waste water diverted to a protected area such as a sediment trap, basin, or area protected
by coir logs.
6. Geolextile fabric underlines. May be used under wet conditions or with soils with a high
seasonal water table to provide greater bearing strength.
Installation:
1. Avoid locating on steep slopes or at curves in public roads.
2. Remove all vegetation and other objectionable material from the foundation area. Grade and
crown for positive drainage.
3. If slope towards the road exceeds 27, construct a 6-8 in. high water bar (ridge) with 3:1
side slopes across the drive area about 15 ft. from the entrance to divert runoff away from
the road into protected sediment basins.
4. Install pipe under the drive if needed to maintain proper public road drainage.
5. Place geotextile fabric on the ground foundation prior to stone placement to improve stability.
6. Place stone to dimensions and grade shown in the erosion and sediment control plan, leaving
the surface smooth and sloped for drainage.
7. Divert all surface runoff and drainage from the stone drive to a sediment trap or basin.
Maintenance:
1. Inspect entrance drive and sediment disposal area weekly and after storm events or heavy
use.
2. Reshape drive as needed for drainage and runoff control.
3. Top dress with clean stone as needed.
4. Immediately remove mud and sediment tracked or washed onto public roads by brushing or
sweeping. Flushing should only be used if the water is conveyed into a sediment trap or
basin.
5. Repair any broken road pavement immediately.
ROM
Requirements:
1. Rock: Hard, angular, and weather -resistant, having a specific gravity of at least
2.5. Gradation: Well -graded stone, 50% (by weight) larger than the specified d50,
and no more than 15% of the pieces (by weight) should be less than 3 in. Filter:
Use geotextile fabric for stabilization and filtration. Slope: 2:1 or flatter, unless
approved in the erosion and sediment control plan. Minimum Thickness: three times
the specified El stone diameter.
Installation:
Subgrade Preparation:
1. Remove brush, trees, stumps, and other debris.
2. Execute only deep enough for both filler and riprap; over -excavation increases the
amount of spoil considerably.
3. Compact any fill material to the density of the surrounding undisturbed soil.
4. Cut a keyway in stable material at the base of the slope to reinforce the toe;
keyway depth should be 1-1/2 times the design thickness of the riprap and should
extend a horizontal distance equal to the design thickness.
5. Smooth the graded foundation.
Fiter Placement:
1. Place geotextile fabric on the smoothed foundation, overlap the edges at least 12
in., and secure with anchor pins spaced every 3 ft. along the overlap.
Riprap Placement:
1. Immediately after installing the filter, add the riprap to full thickness in one
operation. (Do not dump through chutes or use any method that causes
segregation of rock sizes or that will dislodge or damage the underlying flier
material.)
2. If fabric is damaged, remove the riprap and repair by adding another layer of
fabric, overlapping the damaged area by 12 in.
3. Place smaller rock in voids to form a dense, uniform, well -graded mass. (Selective
loading at the quarry and some hand placement may be needed to ensure an even
distribution of rock material.
4. Blend the rock surface smoothly with the surrounding arm to eliminate protrusions
or overfolls.
Maintenance:
1. Inspect periodically for displaced rock material, slumping, and erosion at edges,
especially downstream or downslope. (Properly designed and installed riprap usually
requires very little maintenance if promptly repaired.)
B15 Erosion & sediment control specifications for individual building lots: NONE
SECTION C
Cl Description of pollutants and their sources associated with the proposed land use:
Silt and sediment from exposed soils, leaves, mulch, vehicular sources such as
leaking fuel or oil, brake fluid, brake dust, grease, antifreeze, metals, rubber
fragments, rood grit, sells and sands, construction trash and debris, fertilizers,
household items including but not limited to cleaning agents, chemicals, paint,
miscellaneous home improvement materials, toys, clothing and animal waste,
elevated storm runoff temperatures, acid rain pesticides and pathogens.
C2 Sequence describing storm water quality measure implementation:
1. Inspect and maintain all erosion control measures as detailed in the Storm
Water Pollution Prevention Measures Maintenance Requirements beginning
immediately after installation and continuing until vegetation has been
sufficiently established and all construction activity is complete.
2. Remove all individual inlet protection and coir log check dams, silt fences,
etc. only after seeding and sufficient vegetative growth has been established
in each area to a point where sediment/pollutants will not enter the
downstream ditch and creek system.
3. It is recommended that any proposed wetland areas and plantings (if any)
be constructed/placed after final grading and sufficient vegetative growth has
been established to a point where sediment/pollutants will not enter the
proposed wetlands.
C3 Description of proposed post construction storm water quality measures: Site and
facility design for storm water quality protection on this site employs a
multi -level strategy consisting of:
1. Controlling sources of pollutants.
2. And treating contaminated storm water runoff before discharging it into the
adjacent lagoon system.
Storm water quality measures for reducing, eliminating or controlling pollutants
(source controls) include:
1. Grass Filter Strip: This BMP will filter and encourage infiltration while runoff
is still in sheet flow.
2. Level Spreader Weir: This BMP allowes for sheet flow and small event
infiltration. On larger events, stone will filter the runoff and encourage
infiltration.
3. Outlet Control Structure Sump: This BMP will delay runoff long enough to
encourage suspended solids and pollutants to drop out before runoff enters
the storm system.
4. Extended wetland/Detention Basin: This existing BMP will delay runoff long
enough to encourage suspended solids and pollutants to drop out before
runoff enters regulated drain.
5. Permanent erosion control seeding and plantings
6. Outlet protection & velocity dissipation devices
7. Mulching
It is the intent of this plan that the implementation of the above described
storm water quality measures be executed in accordance with the enclosed plans
and details in order to meet the requirements of Rule 5 storm water quality.
