MINIMUM STANDARDS (MS).
All applicable Virginia Erosion and Sediment Control Regulations and Minimum
Standards shall be adhered to during all phases of construction. These
include, but are not limited to the following:
1. STABLIZATION OF DENUDED AREAS:
Permanent or temporary soil stabilization shall be applied to bare areas
within seven days after final grade is reached on any portion of the site.
Temporary soil stabilization shall be applied within seven days to denuded
areas that may not be at final grade, but will remain dormant or
undisturbed for longer than 30 days. Permanent stabilization shall be
applied at areas that are to be left dormant for more than 1 year.
2. STABILIZATION OF SOIL STOCKPILES:
During construction of the project, soil stockpiles shall be stabilized or
protected with sediment trapping measures. The applicant is responsible for
temporary protection and permanent stabilization of all soil stockpiles on
site as well as soil intentionally transported from the project site.
3. PERMANENT VEGETATIVE COVER
A permanent vegetative cover shall be established on denuded areas not
otherwise permanently stabilized. Permanent vegetation shall not be
considered established until a ground cover is achieve that, in the opinion
of the county Inspector, is uniform and mature enough to survive to inhibit
erosion.
4. TIMING & STABILIZATION OF SILT TRAPPING MEASURES:
Sediment basins and traps, perimeter dikes, sediment barriers and other
measures intended to trap sediment shall be constructed as a first step in
any land disturbing activity and shall be made functional before upslope
land disturbance takes place.
5. STABILIZATION OF EARTHEN STRUCTURES:
Stabilization measures shall be applied to earthen structures such as
dams, dikes and diversions immediately after installation.
6. SEDIMENT TRAPS AND BASINS:
A sediment basin shall control surface runoff from disturbed areas that is
comprised of flow from drainage areas greater than or equal to three acres.
The sediment basin shall be designed and constructed to accommodate the
anticipated sediment loading for the land disturbing activity. The outfall
device or system device shall take into account the total drainage area
flowing through the disturbed area to be served by the basin.
7. CUT AND FILL SLOPES:
Cut and fill slopes shall be designed and constructed in a manner that
will minimize erosion. Slopes that are found to be eroding excessively
within one year of permanent stabilization shall be provided with additional
slope stabilizing measures until the problem is corrected.
& CONCENTRATED RUN-OFF DOWN CUT OR FILL SLOPES:
Concentrated runoff shall not flow down cut or fill slopes unless contained
within an adequate temporary or permanent channel, flume, or slope drain
structure.
9. WATER SEEPS FROM A SLOPE FACE:
Whenever water seeps from a slope face, adequate drainage or other
protection shall be provided.
10. STORM SEWER INLET PROTECTION:
All storm sewer inlets that are made operable during construction shall
be protected so that sediment -laden water cannot enter the conveyance
system without first being filtered or otherwise treated to remove sediment.
11. STABILIZATION OF OUTLETS:
Before newly constructed stormwater conveyance channels are made
operational, adequate outlet protection and any required temporary or
permanent channel lining shall be installed in both the conveyance channel
and receiving channel.
12. WORK IN LIVE WATERCOURSES:
When work in a live watercourse is performed, precautions shall be taken
to minimize encroachment, control sediment transport and stabilize the work
area to the greatest extent possible during construction. Nonerodible
material shall be used for the construction of causeways and cofferdams.
Earthen fill may be used for these structures if armored by nonerodible
cover materials.
13. CROSSING A LIVE WATERCOURSE:
When a live watercourse must be crossed by construction vehicles more
than twice in any six month period, a temporary stream crossing
constructed of nonerodible materials shall be provided.
14. APPLICABLE REGULATIONS:
All applicable federal, state and local regulations pertaining to working in
or crossing live watercourses shall be met.
15. STABILIZATION OF BED AND BANKS
The bed and banks of a watercourse shall be stabilized immediately after
work in the watercourse is completed.
16. UNDERGROUND UTILITIES:
Underground utilities shall be installed in accordance with the following
standards in addition to other criteria:
a.No more than 500 linear feet of trench may be opened at one time.
b.Excavated material shall be placed on the uphill side of trenches
c. Effluent for dewatering operations shall be filtered or passed through
approved sediment trapping device, or both, and discharged in a manner
that does not adversely affect flowing streams or offsite property.
d.Material used for backfilling trenches shall be properly compacted in order
to minimize erosion and promote stabilization.
e.Restabilization shall be accomplished in accordance with these regulations.
f. Applicable safety regulations shall be complied with.
17. CONSTRUCTION ACCESS ROUTES:
Where construction vehicle access routes intersect paved public roads,
provisions shall be made to minimize the transport of sediment by vehicular
tracking onto paved surfaces. Where sediment is transported on to a
public road surface, the road shall be cleaned thoroughly at the end of
each day. Sediment shall be removed by shoveling or sweeping and
transported to a sediment control disposal area. Street washing shall be
allowed only after sediment is removed in this manner. This provision shall
apply to individual lots as well as to larger land disturbing activities.
18. TEMPORARY E&S CONTROL MEASURE REMOVAL:
All temporary erosion and sediment control measures shall be removed
within 30 days after final site stabilization or after temporary measures are
no longer needed, unless otherwise authorized by the local program
authority. Trapped sediment and the disturbed soil areas resulting from the
disposition of temporary measures shall be permanently stabilized to prevent
further erosion and sediment.
19. ADEQUACY OF RECEIVING CHANNELS:
Properties and waterways downstream from the development site shall be
protected from sediment deposition, erosion and damage, due to increases
in volume, velocity and peak flow rates of stormwater runoff for the stated
frequency storm of 24-hour duration.
