SILT FENCE MAINTENANCE NOTES.
Sediment fence requires a great deal of maintenance. Inspect sediment
fences periodically and after each rainfall event.
Should fabric tear, decompose, or in any way become ineffective, replace
it immediately. Replace burlap at least every 60 days.
Remove sediment deposits promptly to provide adequate storage volume
for the next rain and to reduce pressure on fence. Take care to avoid and
fence during clean out.
Remove all fencing materials and unstable sediment deposits after the
contributing drainage area has been properly stabilized, inspected, and
approved. Bring the disturbed area to grade and stabilize as shown in the
vegetation plan.
GRAVEL CONSTRUCTION ENTRANCE MAINTENANCE NOTES:
Inspect entrance%xit pad and sediment disposal area weekly and after
heavy rains or heavy use.
Reshape pad as needed for drainage and runoff control.
Top dress with clean stone as needed.
Immediately remove mud and sediment tracked or washed onto public
road. Repair any broken road pavement immediately.

inspection personnel to be in jeopardy, the inspection maybe delayed until the next
business day on which it is safe to perform the inspection. In addition, when a
storm event of equal to orgreater than 1.0 inch occurs outside of normal business
hours, the self -inspection shall be performed upon the commencement ofthe next
business day. Any time when inspections were delayed shall be noted in the
Inspection Record.

3. Identify leaks and repair as soon as feasible, or remove leaking equipment
from the project.
4. Collect all spent fluids, store in separate containers and properly dispose as
hazardous waste (recycle when possible).
5. Remove leaking vehicles and construction equipment from service until the
problem has been corrected.
6. Bring used fuels, lubricants, coolants, hydraulic fluids and other petroleum
products to a recycling or disposal center that handles these materials.
I LIU.M BUILDING MA TERIAL AND LAND CLEARING WASTE I
2. Provide a sufficient number and size of waste containers (e.g dumpster, trash
receptacle) on site to contain construction and domestic wastes.
3. Locate waste containers at least 50 feet away from storm drain inlets and
surface waters unless no other alternatives are reasonably available.
4. Locate waste containers on areas that do not receive substantial amounts of
runoff from upland areas and does not drain direct/ to a storm drain stream
p Y ,
or wetland.
5. Cover waste containers at the end of each workday and before storm events or
provide secondary containment. Repair or replace damaged waste containers.
6. Anchor all lightweight items in waste containers during times of high winds.
7 Empty waste containers as needed to prevent overflow. Clean up immediately
if containers overflow.
8. Dispose waste off -site at an approved disposal facility.
9. On business days, clean up and dispose of waste in designated waste
PAIN19(]1$}i LIQUID WASTE
wetlands.
2. Locate paint washouts at least 50 feet away from storm drain inlets and surface
waters unless no other alternatives are reasonably available.
3. Contain liquid wastes in a controlled area.
4. Containment must be labeled sized and laced appropriately for the needs of
p
site.
5. Prevent the discharge of soaps, solvents, detergents and other liquid wastes
from construction sites.
PORTABLE TOILETS
1. Install portable toilets on level ground, at least 50 feet away from storm drains,
streams or wetlands unless there is no alternative reasonably available. If 50
foot offset is not attainable, provide relocation of portable toilet behind silt
fence or place on a gravel pad and surround with sandbags.
2. Provide staking or anchoring ofportable toilets during periods of high winds or
in high foot traffic areas.
3. Monitor portable toilets for leaking and properly dispose of any leaked material.
Utilize a licensed sanitary waste hauler to remove leaking portable toilets and
replace with properly operating unit.
1. Show stockpile locations on plans. Locate earthen -material stockpile areas at
least 50 feet away from storm drain inlets, sediment basins, perimeter sediment
controls and surface waters unless it can be shown no other alternatives are
reasonably available.
2. Protect stockpile with silt fence installed along toe ofslope with a minimum
offset of five feet from the toe of stockpile.
3. Provide stable stone access point when feasible.
4. Stabilize stockpile within the timeframes provided on this sheet and in
accordance with the approved plan and any additional requirements. Soil
stabilization is defined as vegetative, physical or chemical coverage techniques
that will restrain accelerated erosion on disturbed soils for temporary or
permanent control needs.

1. Do not discharge concrete or cement slurry from the site.
2. Dispose of, or recycle settled, hardened concrete residue in accordance with
local and state solid waste regulations and at an approved facility.
3. Manage washout from mortar mixers in accordance with the above item and in
addition lace the mixer and associated materials on impervious barrier and
p p
within lot perimeter silt fence.
4. Instal/ temporary concrete washouts per local requirements, where applicable.
If an alternate method or product is to be used, contact your approval
authority for review and approval if local standard details are not available,
use one of the two types of temporary concrete washouts provided on this
detail.
5. Do not use concrete washouts for dewatering or storing defective curb or
sidewalk sections. Storm water accumulated within the washout may not be
pumped into or discharged to the storm drain system or receiving surface
waters. Liquid waste must be pumped out and removed from project.
6. Locate washouts at least 50 feet from storm drain inlets and surface waters
unless it can be shown that no other alternatives are reasonably available. At a
minimum, install protection ofstorm drain inlet(s) closest to the washout
which could receive spills or overflow.
7. Locate washouts in an easily accessible area, on level ground and install a
stone entrance pad in front ofthe washout. Additional controls may be
required by the approving authority.
8. Install at least one sign directing concrete trucks to the washout within the
project limits. Post signage on the washout itself to identify this location.
9. Remove leavings from the washout when at approximately 75%capacity to
limit overflow events. Replace the tarp, sand bags or other temporary
structural components when no longer functional. When utilizing alternative or
proprietary products, follow manufacturer's instructions.
10. At the completion of the concrete work, remove remaining leavings and
dispose of in an approved disposal facility. Fill pit, if applicable, and stabilize
any disturbance caused by removal of washout.
HERBICIDES, PESTICIDES AND RODENTICIDES
1. Store and apply herbicides, pesticides and rodenticides in accordance with label
restrictions.
2. Store herbicides, pesticides and rodenticides in their original containers with
the label, which lists directions for use, ingredients and first aid steps in case
ofaccidental poisoning.
3. Do not store herbicides, pesticides and rodenticides in areas where flooding is
possible or where they may spill or leak into wells, stormwater drains, ground
water orsurface water. /fa spill occurs, clean area immediately.
4. Do not stockpile these materials onsite.
-HAZARDOUS AND TOXIC WASTE
1. Create designated hazardous waste collection areas on -site.
2. Place hazardous waste containers undercover or in secondary containment.
3. Do not store hazardous chemicals, drums or bagged materials directly on the
ground.
