Baffles need to be installed correctly in order to fully provide their benefits.
Refer to Figure 6.65b and the following key points:
• The baffle material needs to be secured at the bottom and sides using
staples.
• Most of the sediment will accumulate in the first bay, so this should be
readily accessible for maintenance.

Maintenance Continue to care for the site until the new owner takes possession. Take
these steps after all materials and equipment have been removed from the
site:
• Remove tree protection zone fences.
• Prune any damaged trees. In spite of precautions, some damage to protected
trees may occur. In such cases, repair any damage to the crown, trunk, or
root system immediately.
• Repair roots by cutting off the damaged areas and painting them with tree
paint. Spread peat moss or moist topsoil over exposed roots.
• Repair damage to bark by trimming around the damaged area as shown in
Figure 6.05d, taper the cut to provide drainage, and paint with tree paint.
• Cut off all damaged tree limbs above the tree collar at the trunk or main
branch. Use three separate cuts as shown in Figure 6.05d to avoid peeling
bark from healthy areas of the tree.
• Continue maintenance care. Pay special attention to any stressed, diseased, or
insect -infested trees. Reduce tree stress caused by unintended construction
damage by optimizing plant care with water, mulch, and fertilizer where
appropriate. Consult your tree expert if needed.
• Inform the property owner about the measures employed during construction,
why those measures were taken, and how the effort can be continued.

Figure 6.52a Block and gravel drop inlet protection.
Construction 1. Lay one block on each side of the structure on its side in the bottom row
to allow pool drainage. The foundation should be excavated at least 2 inches
Specifications below the crest of the storm drain. Place the bottom row of blocks against
the edge of the storm drain for lateral support and to avoid washouts when
overflow occurs. If needed, give lateral support to subsequent rows by placing
2 x 4 wood studs through block openings.
2. Carefully fit hardware cloth or comparable wire mesh with''/2-inch openings
over all block openings to hold gravel in place.
3. Use clean gravel, 3/4- to 'h-inch in diameter, placed 2 inches below the top
of the block on a 2:1 slope or flatter and smooth it to an even grade. DOT #57
washed stone is recommended.

Figure 6.83b Stone check dam stone should be placed over the channel banks to keep water from cutting around the
dam.
Maintenance Inspect check dams and channels at least weekly and after each significant (1 /2
inch or greater) rainfall event and repair immediately. Clean out sediment,
straw, limbs, or other debris that could clog the channel when needed.
Anticipate submergence and deposition above the check dam and erosion from
high flows around the edges of the dam. Correct all damage immediately. If
significant erosion occurs between dams, additional measures can be taken
such as, installing a protective riprap liner in that portion of the channel
(Practice 6.31, Riprap-line and Paved Channels).
Remove sediment accumulated behind the dams as needed to prevent damage
to channel vegetation, allow the channel to drain through the stone check dam,
and prevent large flows from carrying sediment over the dam. Add stones to
dams as needed to maintain design height and cross section.

Figure 6.20b Temporary gravel diversion dike for vehicle crossing (modified from Va MCC).
►j
Plan temporary diversions to function 1 year or more, or they may be
constructed anew at the end of each day's grading operation to protect new fill.
Diversions that are to serve longer than 30 working days should be seeded and
mulched as soon as they are constructed to preserve dike height and reduce
maintenance.
Where design velocities exceed 2 ft/sec, a channel liner is usually necessary to
prevent erosion (Table 8.05a, Appendix 8.05).
Temporary diversions may serve as in -place sediment traps if overexcavated 1
to 2 feet and placed on a nearly flat grade. The dike serves to divert water as
the stage increases. A combination silt fence and channel in which fill from
the channel is used to stabilize the fence can trap sediment and divert runoff

RAVINE GENERAL NOTES:
1. THE RAVINE IS TO BE EXCAVATED TO A SUBGRADE NO LESS THAN ONE FOOT BELOW FINISH GRADE.
2. WASTE REMOVED FROM THE RAVINE EXCAVATION IS TO BE STOCKPILED IN AN APPROVED LOCATION AS DETERMINED BY THE CONTRACTOR AND ENGINEER.
3. THE BURIAL PIT SHOULD BE LINED WITH A GEOTEXTILE FABRIC (MATTING "B") AS SHOWN IN DETAIL THIS SHEET TO SEPARATE ALL EXPOSED WASTE MATERIAL AND FILL
COVER SOIL.
4. AFTER THE RAVINE HAS REACHED SUBGRADE (FINISH GRADE MINUS ONE FOOT IN ELEVATION), PLACE AND COMPACT 6" OF FILL SOIL AS SHOWN ON PROFILE DETAIL,
THIS SHEET. ABOVE THE FILL SOIL, PLACE GEOTEXTILE FABRIC (MATTING "C") OVER ENTIRE AREA. PLACE PRESTO GEOWEB GW20V4 (DEPTH = 4") OVER FABRIC AND
REINFORCE IN PLACE USING STAKES AND KEYS AS RECOMMENDED BY THE MANUFACTURER.
5. MATTING "B" IS TO BE PLACED BELOW THE RIP RAP OUTFALL BEYOND THE EXTENDED 42" CMP STORM PIPE.
6. IT IS ESSENTIAL THAT ENOUGH PLASTIC POLY SHEETING BE KEPT ONSITE TO BE ABLE TO COVER THE ENTIRE DISTURBED AREA OF THE RAVINE. THE SHEETING MUST
BE PLACED DURING ANY RAINSTORM OR BEFORE ANY FORECASTED RAIN EVENT. MATERIALS TO HOLD THE SHEETING IN PLACE DURING HEAVY RAINS AND/OR WINDS
MUST ALSO BE UTILIZED WHEN COVERING DISTURBED AREAS. METHODS TO RESTRAIN THE SHEETING COULD INCLUDE USING HEAVY ITEMS (TIRES, CONSTRUCTION
CHAINS, LOGS, LARGE ROCKS, ETC.). GROUND COVER ANCHORING PINS COULD ALSO BE USED (MINIMUM LENGTH OF 6-INCHES) IF THE SHEETING MATRIAL IS FOLDED
OVER AT LEAST TWICE SO THAT THE PINS PUNCTURE THROUGH AT LEAST THREE LAYERS OF THE SHEETING. BY COVERING THE OPEN AREAS DURING EACH PHASE,
THIS WILL HELP ELIMINATE SEDIMENTATION.
7. ALL DISTURBED AREAS ARE TO BE SEEDED AND MATTED PER THE NOTES ON THIS PAGE IMMEDIATELY AFTER FINAL GRADING HAS BEEN ESTABLISHED.

Instructions
1. Prepare soil before installing rolled erosion control
products (RECPs), including any necessary application of
lime, fertilizer, and seed. Ground surface must be free of
debris, rocks, clay clods and raked smooth sufficient to
allow intimate contact of the RECP with the soil over the
entirety of the installation.
2. Begin at the top of the channel by anchoring the RECPs in
a 6" (15 cm) deep X 6" (15 cm) wide trench with
approximately 12" (30 cm) of RECPs extended beyond the
up -slope portion of the trench. Use ShoreMax mat at the
channel/culvert outlet as supplemental scour protection
as needed. Anchor the RECPs with a row of
staples/stakes approximately 12" (30 cm) apart in the
bottom of the trench. Backfill and compact the trench
after stapling. Apply seed to the compacted soil and fold
the remaining 12" (30 cm) portion of RECPs back over the
seed and compacted soil. Secure RECPs over compacted
soil with a row of staples/stakes spaced approximately
12" (30 cm) apart across the width of the RECPs.
3. Roll center RECPs in direction of water flow in bottom of
channel. RECPs will unroll with appropriate side against
the soil surface. All RECPs must be securely fastened to
soil surface by placing staples/stakes in appropriate
locations as shown in the staple pattern guide.
4. Place consecutive RECPs end -over -end (Shingle style) with
a 4"- 6" (10 - 15 cm) overlap. Use a double row of staples
staggered 4" apart and 4" on center to secure RECPs.
gg P
5. Full length edge of RECPs at to of side slopes mwst be
� g P P
anchored with a row of staples/stakes spaced at ST apart
in a 6" (15 cm) deep X 6"(15 cm) wide trench. Backfill and
compact the trench after stapling.
6. Adjacent RECPs must be overlapped approximately 4"- 6"
(10 -15 cm) and secured with staples/stakes at ST.
7. In high flow channel applications a staple check slot is
recommended at 30 to 40 foot (9 -12m) intervals. Use a
double row of staples staggered 6" (15 cm) apart and 12"
(30 cm) on center over entire width of the channel.
8. The terminal end of the RECPs must be anchored with a
row of staples/stakes spaced at ST apart in a 6" (15 cm)
deep X 6" (15 cm) wide trench. Backfill and compact the
trench after stapling.
9. Fasteners should provide a minimum of twenty pounds of
pullout resistance. Six-inch (10 cm) X one -inch (2.5 cm)
eleven gauge staples are typically adequate. In loose
soils, longer staples may be necessary, twist puns can
provide the greatest pullout resistance. In hard or rocky
soils, straight pins may by used where staples or twist pins
are refused, provided the minimum pullout requirements
are met.

1.0 NARRATIVE
1.1 PROJECT DESCRIPTION
CDG ENGINEERS AND ASSOC. HAS PREPARED THIS EROSION AND SEDIMENT CONTROL (E&SC) PLAN UNDER CONTRACT TO THE
NORTH CAROLINA DEPARTMENT OF ENVIRONMENTAL QUALITY (NCDEQ) PRE -REGULATORY LANDFILL UNIT (UNIT). THIS PLAN
DETAILS EROSION AND SEDIMENT CONTROL MEASURES TO BE TAKEN DURING REMEDIATION CONSTRUCTION ACTIVITIES PLANNED
TO ADDRESS WASTE HISTORICALLY BURIED AT THE SIMS LEGION PARK (SITE). THE REMEDIATION CONSTRUCTION ACTIVITIES WILL
INCLUDE THE CLEARING OF MUCH OF THE WORK AREA, THE EXCAVATION, REMOVAL, AND RELOCATION ON -SITE OF WASTE
MATERIAL WITHIN THE EXISTING LIMITS OF WASTE BOUNDARY, AND THE PLACEMENT AND COMPACTION OF ON -SITE SOIL FILL
MATERIAL.
1.2 SITE DESCRIPTION
THE SITE IS LOCATED IN GASTONIA, NORTH CAROLINA ON THE EAST SIDE OF AN UNNAMED TRIBUTARY TO LONG CREEK ADJACENT
TO THE INTERSECTION OF US 321 AND 185. THE WASTE DISPOSAL AREA EXTENDS ACROSS A VAST PORTION OF THE LEGION PARK
PROPERTY, INCLUDING A SMALL PIECE ON THE NORTH SIDE OF 1-85 AND A SMALL PORTION ON A RESIDENTIAL PROPERTY SOUTH
OF THE PARK. THE ENTIRE WASTE AREA CONSIST OF APPROXIMATELY 20.88 ACRES. HOWEVER, 4.01 ACRES OF THE OLD LANDFILL
FALLS WITHIN THE 1-85 RIGHT OF WAY AND WILL NOT BE SUBJECT TO THIS PROJECT, LEAVING 16.87 ACRES OF THE ACTUAL
LANDFILL TO BE ASSOCIATED WITH THESE DRAWINGS. THE PROJECT PROPOSES TOTAL DISTURBANCE OF 19.2 ACRES. THE
GASTON COUNTY PROPERTY IDENTIFICATION NUMBER [PIN] FOR THE PARCEL IS #3546847560 WHILE THE SMALL RESIDENTIAL
PORTION IS PARCEL #3546738496. THE ENTIRE WASTE DISPOSAL AREA IS CURRENTLY COVERED WITH VEGETATION (MOSTLY
WOODED GROWTH) AND OPEN SPACE (ASPHALT PARKING LOT, BASEBALL FIELDS, ETC. THERE IS AN OUTFALL DITCH THAT
CONVEYS STORMWATER FROM MUCH OF THE PARK PROPERTY THROUGH EXISTING STORM PIPES AND EVENTUALLY INTO THE
UNNAMED TRIBUTARY. THIS OUTFALL DITCH HAS BEEN CLASSIFIED AS A PERENNIAL STREAM BASED ON A JURISDICTIONAL
DETERMINATION REQUEST (JDR) THAT WAS APPROVED BY THE US CORPS OF ENGINEERS ON MARCH 20, 2019 (SAW-2018-00034).
THE PROJECT SITE IS LOCATED WITHIN THE LONG CREEK WATERSHED AND CATAWBA RIVER BASIN. IN GENERAL, STORMWATER
FLOWS VIA SHEET FLOW AND THE DRAINAGE FEATURE TOWARDS THE WESTERN EDGE OF THE PROJECT SITE BOUNDARY. AFTER
IT LEAVES THE PROPERTY, THE FLOW CONTINUES NORTH UNDER 1-85 TRAVELING NORTH NORTH EAST FOR APPROXIMATELY 3,900
FEET UNTIL IT EMPTIES INTO LONG CREEK. THE RIVER HAS A'C' CLASSIFICATION MEANING "AQUATIC LIFE, SECONDARY CONTACT
RECREATION, FRESH WATER".
1.3 ADJACENT PROPERTY
THE PROJECT SITE, WHICH HAS A CURRENT PROPERTY USE AS "EXEMPT", IS CURRENTLY LOCATED WITHIN THE GASTONIA
TOWNSHIP. THE WESTERN EDGE OF THE PROPERTY IS BOUNDED BY THE UNNAMED TRIBUTARY, TO THE NORTH BY 1-85 AND
RANKIN LAKE ROAD, TO THE EAST BY DR. MARTIN LUTHER KING JR. WAY, AND TO THE SOUTH BY SYCAMORE AVENUE.
1.4 SOIL INFORMATION
ACCORDING TO THE NATURAL RESOURCES CONSERVATION SERVICE'S SOIL SURVEY, THE PROJECT FALLS WITHIN A ZONE
CONSISTING OF 88.2% CECIL-URBAN, 11.2% CHEWACLA LOAM, AND 0.6% MADISON SANDY CLAY LOAM..
1.5 PLANNED EROSION AND SEDIMENTATION CONTROL PRACTICES
THE EROSION AND SEDIMENTATION CONTROL MEASURES PROVIDED HEREIN WERE DESIGNED AND SPECIFIED IN GENERAL
ACCORDANCE WITH THE EROSION AND SEDIMENT CONTROL PLANNING AND DESIGN MANUAL PUBLISHED BY NCDEQ.
1.5.1 LAND GRADING (6.02)
THIS PROJECT DEALS PRIMARILY WITH THE ON -SITE RELOCATION OF BURIED WASTE MATERIAL (WHERE REQUIRED), THE
PLACEMENT AND COMPACTION OF FILL SOILS, AND THE FINE GRADING AND SEEDING OF THE FINAL GRADE. GRADING WILL BE
DONE IN PHASES TO HELP MINIMIZE EROSION.
1.5.2 SEDIMENT FENCE (6.62)
SILT FENCE WILL BE INSTALLED AROUND THE PERIMETER OF THE PLANNED DISTURBED AREA TO LIMIT THE AMOUNT OF
POTENTIAL SEDIMENT LEAVING THE SITE. IT WILL ALSO BE PLACED AROUND ANY SOIL STOCKPILE AREA THAT WILL BE UTILIZED.
ANY REQUIRED REPAIRS DURING THE GRADING OPERATIONS WILL BE MADE IMMEDIATELY. SEDIMENT DEPOSITS WILL BE
REMOVED AFTER EACH STORM EVENT, AND WHEN DEPOSITS REACH APPROXIMATELY ONE-HALF THE HEIGHT OF THE BARRIER.
ANY SEDIMENT DEPOSITS REMAINING IN PLACE AFTER THE SILT FENCE IS NO LONGER REQUIRED WILL BE DRESSED TO
CONFORM TO THE EXISTING GRADE, REPAIRED, AND SEEDED. SEDIMENT FENCE WILL BE INSTALLED AS PER PLAN AND/OR AS
NEEDED.
1.5.3 SURFACE STABILIZATION
SURFACE STABILIZATION WILL BE ACCOMPLISHED WITH MATTING, VEGETATION AND MULCH AS SPECIFIED IN THE VEGETATION
PLAN. VEGETATION WILL BE PLANTED IMMEDIATELY UPON THE COMPLETION OF FINAL GRADING. TEMPORARILY STABILIZE
DENUDED AREAS THAT WILL NOT BE BROUGHT TO FINAL GRADE FOR A PERIOD OF MORE THAN THE NUMBER OF CALENDAR
DAYS AS THEY ARE LISTED IN THE STABILIZATION CHART ON DRAWING #16.
1.5.4 CONSTRUCTION ENTRANCE (6.06)
WHERE CONSTRUCTION VEHICLE ACCESS ROUTE INTERSECTS OFF -SITE WORK AREAS, PROVISIONS SHALL BE MADE TO
MINIMIZE THE TRANSPORT OF SEDIMENT BY VEHICULAR TRACKING ONTO PAVED SURFACES. WHERE SEDIMENT IS
TRANSPORTED ONTO A PAVED OR PUBLIC ROAD SURFACE, THE ROAD WILL BE CLEANED THOROUGHLY AT THE END OF EACH
DAY. SEDIMENT WILL BE REMOVED FROM THE ROADS BY SHOVELING OR SWEEPING AND TRANSPORTING TO A SEDIMENT
CONTROL DISPOSAL AREA. STREET WASHING WILL BE ALLOWED ONLY AFTER SEDIMENT IS REMOVED IN THE MANNER
DESCRIBED HEREIN. A TEMPORARY CONSTRUCTION ENTRANCE WILL BE PROVIDED AT THE SITE PRIOR TO THE START OF
CONSTRUCTION. AN OPEN GRADED STONE BASE ENTRANCE WILL BE PROVIDED AT THE SITE TO HELP LIMIT THE SOIL TRACKED
OFFSITE BY CONSTRUCTION TRAFFIC. THE APPROXIMATE LOCATION OF THE CONSTRUCTION ENTRANCES AND DETAILS ARE
PROVIDED ON DRAWINGS #4, 5, 6, AND 7.
1.5.5 DUST CONTROL (6.84)
DUST CONTROL IS NOT EXPECTED TO BE A PROBLEM. SHOULD EXCESSIVE DUST BE GENERATED, SPRINKLING OF WATER ON
THE PROBLEM AREAS WILL BE CONDUCTED TO MINIMIZE THE PROBLEM.
1.5.6 TEMPORARY DIVERSIONS (6.20)
TEMPORARY DIVERSIONS WILL BE UTILIZED DURING THE PROJECT TO HELP DIRECT SEDIMENTATION TOWARDS ONE OF THE
FOUR TEMPORARY SEDIMENT TRAPS. THESE TEMPORARY DIVERSIONS MAY HAVE TO BE FIELD ADJUSTED DURING THE
DURATION OF THE PROJECT BASED ON DAILY CONSTRUCTION ACTIVITIES AND/OR ACTUAL FIELD CONDITIONS. CONTACT CDG
AND/OR THE NCDEQ FIELD INSPECTOR PRIOR TO ANY MAJOR DIVERSION FROM THE APPROVED DRAWINGS.
IT IS ESSENTIAL THAT ENOUGH PLASTIC POLY SHEETING BE KEPT ONSITE TO BE ABLE TO COVER THE ENTIRE DISTRUBED AREA
IN THE RAVINE. THE SHEETING MUST BE PLACED IN THE RAVINE AREA DURING ANY RAINSTORM OR BEFORE ANY FORECASTED
RAIN EVENT. MATERIALS TO HOLD THE SHEETING IN PLACE DURING HEAVY RAINS AND/OR WINDS MUST ALSO BE UTILIZED
WHEN COVERING DISTURBED AREAS. METHODS TO RESTRAIN THE SHEETING COULD INCLUDE USING HEAVY ITEMS (TIRES,
CONSTRUCTION CHAINS, LOGS, LARGE ROCKS, ETC.). GROUND COVER ANCHORING PINS COULD ALSO BE USED (MINIMUM
LENGTH OF 6-INCHES) IF THE SHEETING MATRIAL IS FOLDED OVER AT LEAST TWICE SO THAT THE PINS PUNCTURE THROUGH AT
LEAST THREE LAYERS OF THE SHEETING. BY COVERING THE OPEN AREAS DURING EACH PHASE, THIS WILL HELP ELIMINATE
SEDIMENTATION. THE POLY SHEETING SHOULD ALSO BE PLACED OVER ANY AREAS EXPOSED OF WASTE MATERIAL DURING THE
GRADING OF THE TEMPORARY SEDIMENT TRAPS. THE SHEETING MUST BE "KEYED" INTO THE SIDES OF THE TRAPS TO KEEP
THEM IN PLACE DURING RAIN EVENTS. NONWOVEN GEOTEXTILE FABRIC SHOULD BE PLACED UNDER THE RIP RAP OUTFALLS
AND EMERGENCY SPILLWAYS.
2.0 MAINTENANCE PLAN
THE CONTRACTOR WILL BE RESPONSIBLE FOR MAINTENANCE OF THE EROSION CONTROL MEASURES DURING THE CONSTRUCTION
OF THE PROJECT. ONCE THE PROJECT HAS BEEN COMPLETED, THE OWNER OF THE FACILITY WILL BECOME RESPONSIBLE FOR
MAINTAINING THE PERMANENT MEASURES. TYPICAL MAINTENANCE ISSUES INCLUDE THE FOLLOWING:
1. ALL EROSION AND SEDIMENT CONTROL PRACTICES WILL BE CHECKED FOR STABILITY AND OPERATION AFTER ANY
RAINFALL EVENT OF 1.0" OR GREATER OR AT LEAST ONCE EVERY SEVEN DAYS PER THE NPDES PERMIT. ANY NEEDED
REPAIRS WILL BE MADE IMMEDIATELY TO MAINTAIN ALL PRACTICES AS DESIGNED.
2. SEDIMENT ACCUMULATIONS IN ALL SEDIMENT BASINS WILL BE REMOVED ONCE THE MATERIAL REACHES HALF THE DEPTH
OF THE INDIVIDUAL BASIN.
3. SEDIMENT WILL BE REMOVED FROM BEHIND THE SEDIMENT FENCE WHEN IT BECOMES APPROXIMATELY 0.5 FEET IN DEPTH
OR GREATER AT THE FENCE. THE SEDIMENT FENCE WILL BE REPAIRED AS NECESSARY TO MAINTAIN A BARRIERS.
4. ALL SEEDED AREAS WILL BE FERTILIZED, RESEEDED AS NECESSARY, AND MULCHED ACCORDING TO SPECIFICATIONS IN
THE VEGETATIVE PLAN TO MAINTAIN A VIGOROUS, DENSE VEGETATIVE COVER.
GENERAL NOTES FOR: SIMS LEGION PARK LANDFILL
3.0 SPECIFICATIONS
3.1 LAND GRADING
1. LAND GRADING SHALL BE KEPT TO A MINIMUM AT ALL TIMES.
2. FINAL GRADING SHOULD BE SLOPED SO THAT STORM RUNOFF SHEET FLOWS AS SHOWN ON THE DRAWINGS.
3. WHEN THE AREA HAS BEEN PROPERLY STABILIZED AND APPROVED BY THE EROSION & SEDIMENT CONTROL INSPECTOR,
ALL OF THE TEMPORARY SEDIMENT AND EROSION CONTROL MEASURES WILL BE REMOVED AND THE DISTURBED AREA
GRADED TO BLEND WITH THE SURROUNDING AREA AND VEGETATED.
3.2 SEDIMENT FENCE AND EROSION CONTROL WATTLES
1. CONSTRUCT THE SEDIMENT FENCE OR EROSION CONTROL WATTLES AT THE LOCATIONS SHOWN ON THE DRAWINGS.
2. LOCATE POSTS DOWN SLOPE OF FABRIC TO HOLD FENCING.

DURATION OF THE PROJECT. A CONSTRUCTION ENTRANCE, AS DETAILED ON DRAWING #9, SHALL BE UTILIZED TO HELP W
ELIMINATE SEDIMENT ON CONSTRUCTION VEHICLES FROM LEAVING THE SITE.
2. USE CRUSHED STONE 2" - 3" IN SIZE.
3. THE GRAVEL CONSTRUCTION ENTRANCE AND ACCESS WAYS SHALL BE MAINTAINED IN A CONDITION TO PREVENT MUD OR
SEDIMENT FROM LEAVING THE SITE. SHOULD MUD BE TRACKED OR WASHED ONTO PUBLIC ROADS, IT MUST BE REMOVED
IMMEDIATELY.
3.4 TEMPORARY SKIMMER BASIN
FOUR (4) TEMPORARY SKIMMER BASINS WILL BE INSTALLED ON THE WEST SIDE OF THE SITE WHERE THEY WILL CATCH
SEDIMENT-LAIDEN RUNOFF FROM THE WORK AREA. THESE SEDIMENT BASINES SHALL BE INSPECTED AFTER EACH RAINFALL
EVENT AND REPAIRS ARE TO BE MADE AS NEEDED. THE SEDIMENT BASINS SHOULD BE CLEANED OUT IF THE SEDIMENT
LEVELS REACH HALF THE HEIGHT OF THE BAFFLES. ACCESS TO THE SEDIMENT BASINS FOR CLEARING AND MAINTENANCE
PURPOSES SHALL BE MAINTAINED THROUGHOUT THE PROJECT.

Note: After the permanent cessation of construction activities, any areas with temporary
ground stabilization shall be converted to permanent ground stabilization as soon as
practicable but in no case longer than 90 calendar days after the last land disturbing
activity. Temporary ground stabilization shall be maintained in a manner to render the
surface stable against accelerated erosion until permanent ground stabilization is achieved.
GROUND STABILIZATION SPECIFICATION
Stabilize the ground sufficiently so that rain will not dislodge the soil. Use one of the
techniques in the table below:
Temporary Stabilization
Permanent Stabilization
• Temporary grass seed covered with straw or
• Permanent grass seed covered with straw or
other mulches and tackifiers
other mulches and tackifiers
• Hydroseeding
• Geotextile fabrics such as permanent soil
• Rolled erosion control products with or
reinforcement matting
without temporary grass seed
• Hydroseeding
• Appropriately applied straw or other mulch
• Shrubs or other permanent plantings covered
• Plastic sheeting
with mulch
• Uniform and evenly distributed ground cover
sufficient to restrain erosion
• Structural methods such as concrete, asphalt or
retaining walls
• Rolled erosion control products with grass seed
POLYACRYLAMIDES (PAMS) AND FLOCCULANTS
1. Select flocculants that are appropriate for the soils being exposed during
construction, selecting from the NCDWR List ofApprovecd PAMS/F/occu/ants.
2. Apply flocculants at or before the inlets to Erosion and Sediment Control Measures.
3. Apply flocculants at the concentrations specified in the NCDWR List ofAlpproved
PAMS/Flocculants and in accordance with the manufacturer's instructions.
4. Provide ponding area for containment of treated Stormwater before discharging
offsite.
5. Store flocculants in leak -proof containers that are kept under storm -resistant cover
or surrounded by secondary containment structures.
EQUIPMENT AND VEHICLE MAINTENANCE
1. Maintain vehicles and equipment to prevent discharge of fluids.
2. Provide drip pans under any stored equipment.
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.
LITTER, BUILDING MATERIAL AND LAND CLEARING WASTE
1. Never bury or burn waste. Place litter and debris in approved waste containers.
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 directly to a storm drain, stream 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 containers.
PAINT AND OTHER LIQUID 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.
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.
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.
2. Protect stockpile with silt fence installed along toe of slope 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 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 temporary concrete washouts provided on this detail.
5. Do not use concrete washouts for dewatering or storing 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.
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 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. 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.
