Never bury or burn waste. Place litter and debris in approved waste containers.
Provide a sufficient number and size of waste containers (e.g dumpster, trash
receptacle) on site :to contain construction and domestic wastes.
Locate waste containers at least 50 feet away from storm drain inlets and surface
waters unless no other alternatives are reasonably available.
Locate wastecontainers on areas that do not receive substantial amounts of runoff
from upland areas and does not drain directly to a storm drain, stream or wetland.
Cover waste containers at the end of each workday and before storm events or
provide secondary containment. Repair or replace darnaged waste containers.
Anchor all lightweight items in waste containers during times of high winds.
Empty waste containers as needed to prevent overflow. Clean up immediately if
containers overflow.
Dispose waste off -site at an approved disposal facility.
On business days, clean up and dispose of waste in designated waste containers.
PAINT AND OTHER LIQUID D WASTE
1. Do not dump paint and other liquid waste into storm drains, streams or 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 placed appropriately for the needs of 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 sand bags.
2. Provide staking or anchoring of portable toilets during periods of high winds or in high
foot traffic areas.
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.
EARTHEN STOCKPILE MANAGEMENT
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.
Protect stockpile with silt fence installed along toe of slope with a minimum offset of
five feet from the toe of stockpile.
Provide stable stone access point when feasible.
4. Stabilize stockpile within the timeframes provided on this sheet and in accordance
with theapproved plan and anyadditional 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.

CONCRETE WASHOUTS
1, Do not discharge concrete or cement slurry from the site. ,
2 iDispose 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 place the mixer and associated materials on impervious barrier and within
lot perimeter silt fence.
4, Install 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 ternporary concrete washouts provided on this detail.
5,. Do not use concrete washouts for dewatering orstoring defective curb or sidewalk
sections, Stormwater 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.
G. 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 of storm 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 of the washout. Additional controls may be required by the
approving authority.
8. In
stall 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 washoutwhen at approximately 75% capacity to limit
overflow events. Replace the tarp, sand bags or other temporary structural
components when no longer functional.
pg When utilizing alternative or proprietary
products, follow manufacturer's instructions.
10. At. the completion of the concrete work, remove remaining leavirigs and dispose of
in an approved disposal facility. Fill pit, if applicable, and stabilize any disturbance
caused by removal of washout.
