PART 3 - EXECUTION
3.01 EROSION AND SEDIMENT CONTROL
A. Erosion and sediment controls must be constructed, stabilized and functional before site
disturbance within the tributary area to those controls.
B. Upon completion of installation of the erosion and sediment controls, the site will be
inspected and any areas identified with a significant erosion potential will receive fortified
erosion control measures, as determined by the Owner's Representative or other Agency
having jurisdiction.
C. The Contractor shall utilize diversionary tactics for containing runoff and directing it
towards erosion control devices as needed to minimize sedimentation. Existing curbs
shall also be used to divert clean runoff away from inlets.
D. All erosion and sediment control devices must be maintained in working order until the
site is stabilized. All preventative and remedial maintenance work, including clean out,
repair, replacement, re -grading, re -seeding, re -mulching, or re -netting, must be
performed immediately.
E. Any disturbed area on which activity has ceased must be stabilized immediately. During
non -germinating periods, mulch must be applied at the recommended rates.
F. After final stabilization has been achieved, temporary erosion and sediment controls must
be removed. Areas disturbed during removal shall be stabilized immediately.
3.02 Contractor shall implement erosion control measures as shown on the plans and as job
conditions dictate. Intent is to minimize erosion and pollutants at the source, capture sediment at
regular intervals and prevent sediment intrusion into storm sewer pipes, structures, and
waterways. Work includes, but is not limited to, mulching, temporary silt fences, filter fabric,
expeditious grading, stormwater diversion, prompt turf and plant establishment, and maintenance
of same.
3.03 The Contractor shall initiate stabilization measures as soon as practicable in portions of the site
where construction activities have temporarily or permanently ceased, but in no case more than
14 days after the construction activity in that portion of the site has temporarily or permanently
ceased. If disturbed soils surfaces are to be left exposed for a period of greater than 14 days,
stabilize the soil with temporary seeding and/or mulch to limit erosion. Where the initiation of
stabilization measures by the 14th day after construction activity temporarily or permanently
ceased is precluded by snow cover or frozen ground conditions, stabilization measures shall be
initiated as soon as practicable. The onset of seasonally adverse weather is not intended as our
excuse for not implementing the necessary erosion controls. The Contractor shall use foresight
in his activities to only disturb areas that he can stabilize before adverse weather conditions
prevail. The Contractor is encouraged to schedule his work such that final land surface
Skidmore College - North 31 2501 -2 EROSION AND SEDIMENT CONTROL
Broadway Entrance
restoration closely follows initial disturbance to the maximum extent possible in order to limit bare
soil exposure and dependence on the temporary systems discussed above.
3.04 Sediment shall be removed from sediment fences whenever their capacity has been reduced by
fifty (50) percent from the design capacity and/or as required to ensure intent. Prior to fine
grading and restoration, the Contractor shall remove and dispose of accumulated sediments and
silts as required.
3.05 AUTHORITY OF WORK
A. The Owner's Representative has the authority to limit the surface area of erodible earth
material exposed by clearing and grubbing, the surface area of erodible earth material
exposed by excavation, borrow and fill operations and to direct the Contractor to provide
immediate permanent or temporary pollution control measures to prevent contamination
of adjacent streams or other watercourses/waterbodies.
3.06 POLLUTION CONTROL
A. Provide methods, means and facilities required to prevent contamination of soil, water or
atmosphere by the discharge of noxious substances from construction operations.
Promptly repair equipment leaks. Provide equipment and personnel to perform
emergency measures required to contain any spillages, and to remove contaminated
soils or liquids.
B. Notify Owner's Representative if contaminated soil, groundwater or other forms of
pollution are encountered. Excavate and dispose of any contaminated earth immediately
in accordance with Federal, State and local regulations off-site, and replace with suitable
compacted fill.
C. Pollutants such as fuels, lubricants, bitumen's, raw sewage and other harmful materials
shall not be discharged into or near rivers, streams, and impoundments or into natural or
man-made channels leading thereto. Wash water or waste from concrete mixing
operations or trucks shall not be allowed to enter live streams.
3.07 DEWATERING AND WASHWATERS
A. Water from aggregate washing, equipment washing, dewatering or other operations
containing sediment, shall be treated by filtration, settling basin, silt bags or other means
sufficient to reduce the turbidity, so as not to cause a substantial visible contrast to
natural conditions.
3.08 SEDIMENT CONTROL FENCE INSTALLATION
A. A silt fence shall be used where shown on the plans.
B. Embed silt fence material a minimum of 8 inches below finished grade.
C. When two sections of filter cloth adjoin each other, they shall be overlapped by six inches
and folded.
D. Maintenance shall be performed as needed and material removed when Abulges@
develop in the silt fence, or when 6 inches of sediment has accumulated against it,
whichever occurs first. All sediment barriers shall be repaired or replaced when they no
longer function as a barrier.
3.09 CONSTRUCTION OPERATIONS
A. When borrow material is obtained from other than commercially operated sources,
erosion of the borrow site shall be so controlled, both during and after completion of the
work, so that erosion will be minimized and sediment will not enter streams or other
bodies of water. Waste or disposal areas and construction roads shall be located and
constructed in a manner that will minimize sediment -entering streams. Install sediment
containment devices around stockpiles and waste areas. Stabilize the surface of
temporary haul roads to minimize sediment creation.

3.12 FINAL STABILIZATION
A. Final stabilization is defined as all soil disturbing activities at the site have been
completed, and that a uniform perennial vegetative cover with a density of at least 80%
has been established or equivalent stabilization measures (such as the use of mulches or
geotextiles) have been employed on all unpaved areas and areas not covered by
permanent structures.
3.13 REMOVAL OF TEMPORARY EROSION AND SEDIMENT CONTROL MEASURES
A. Remove erosion control devices when final stabilization has occurred for the respective
areas of the site and are no longer needed.
3.15 CONTRACTOR'S RESPONSIBILITY
A. The actual scheduling and implementation of the erosion and sediment control plan and
devices shown are considered to comprise the majority of efforts needed, but not
necessarily all that will be required. Weather, Contractor's schedule, extent of
disturbance, site and unforeseen conditions can dictate that greater efforts will be
necessary.
