Deflector shall be inspected weekly and after each runoff event.
Accumulated sediment shall be removed from deflector within 24 hours of inspection.
Belt shall be replaced when worn and no longer effective.
Deflectors may be used to direct runoff from an access road to a well -vegetated area or
sediment removal facility.
A deflector is typically constructed from rubber belting ranging from 5176" to 112" thick
held between two 2" x 6" wooden planks.
This method of directing runoff from an access road works best on low traffic roads.
deflectors can be used on roads with grades exceeding 10%,

Rock Construction Entrance with Wash Rack
Modified from Smith Cattleguard Company
IF EXCESSIVE AMOUNTS OF SEDIMENT ARE BEING DEPOSITED ON ROADWAY, EXTEND LENGTH OF
ROCK CONSTRUCTION ENTRANCE BY 70 FOOT INCREMENTS UNTIL CONDITION IS ALLEVIATED OR
INSTALL WASH RACK.
Wash rack shall be 20 feet (min.) wide or total width of access.
Wash rack shall be designed and constructed to accommodate anticipated construction
vehicular traffic.
A water supply shall be made available to wash the wheels of all vehicles exiting the site.
MAINTENANCE: Rock construction entrance thickness shall be constantly maintained to the
specified dimensions by adding rock. A stockpile of rock material shall be maintained on site
for this purpose. Drain space under wash rack shall be kept open at all times. Damage to the
wash rack shall be repaired prior to further use of the rack. All sediment deposited on
roadways shall be removed and returned to the construction site immediately. Washing the
roadway or sweeping the deposits into roadway ditches, sewers, culverts, or other drainage
courses is not acceptable.
A metal wash rack or livestock grate is an acceptable alternative to the reinforced concrete
one shown in the standard detail. Approaches to the wash rack should be lined with aashto #1
at a minimum of 25' on both sides. The wash rack should discharge to a sediment removal
facility, such as a vegetated filter strip or into a channel leading to a sediment removal device
(e.g. a sediment trap or sediment basin). Rock construction entrances with wash racks should
be maintained to the specified dimensions by adding rock when necessary at the end of each
workday. A stockpile of rock material should be maintained on site for this purpose.
Sediment deposited on paved roadways should be removed and returned to the construction
site.
NOTE: Washing the roadway or sweeping the deposits into roadway ditches, sewers, culverts,
or other drainage courses is not acceptable. Damaged wash racks should be repaired as
necessary to maintain their effectiveness. In lieu of washrack installation, MVP will extend the
RCE by 70' increments until mud tracking condition is alleviated.

TOPSOILING AND SOIL HANDLING FROM SOUTHGATE
Definition
Methods of preserving and using the surface layer of undisturbed soil, often enriched in organic matter, in
order to obtain a more desirable planting and growth medium.
Purposes
To provide a suitable growth medium for final site stabilization with vegetation and promote successful
reforestation.
Conditions Where Practice Applies
1. Where the preservation or importation of topsoil is determined to be the most effective method of
providing a suitable growth medium.
2. Where the subsoil or existing soil presents the following problems:
a. The texture, pH, or nutrient balance of the available soil cannot be modified by
reasonable means to provide an adequate growth medium.
b. The soil material is too shallow to provide an adequate root zone and to supply necessary
moisture and nutrients for plant growth.
c. The soil contains substances potentially toxic to plant growth.
3. Only on slopes that are 2:1 or flatter unless other measures are taken to prevent erosion and
sloughing.
Planning Considerations
Topsoil is the surface layer of the soil profile, generally characterized as being darker than the subsoil due
to the presence of organic matter. It is the major zone of root development, carrying much of the nutrients
available to plants, and supplying a large share of the water used by plants.
Although topsoil provides an excellent growth medium, there are disadvantages to its use. Stripping,
stockpiling, and reapplying topsoil, or importing topsoil, may not always be cost-effective. Topsoiling can
delay seeding or sodding operations, increasing the exposure time of denuded areas. Most topsoil contains
weed seeds, and weeds may compete with desirable species.
Advantages of topsoil include its high organic matter content and friable consistence, water -holding
capacity, and nutrient content,
In site planning, the option of topsoiling should be compared with that of preparing a seedbed in subsoil.
The clay content of subsoils does provide high moisture availability and deter leaching of nutrients and,
when properly limed and Fertilized, subsoils may provide a good growth medium which is generally free

of weed seeds. In many cases topsoiling may not be required for the establishment of less demanding,
lower maintenance plant material. Topsoil ing is strongly recommended where ornamental plants or high -
maintenance turf will be grown. Topsoi ling is a required procedure when establishing vegetation on
shallow soils, soils containing potentially toxic materials, and soils of critically low pH (high acid) levels.
If topsoiling is to be done, the following items should be considered:
1. Whether an adequate volume of topsoil exists on the site. Topsoil will be spread at a compacted
depth of 2 to 4 inches (depths closer to 4 inches are preferred).
2. Location of the topsoil stockpile so that it meets specifications and does not interfere with work
on the site.
3. Allow sufficient time in scheduling for topsoil to be spread and bonded prior to seeding or
planting.
4. Care must be taken not to apply topsoil to subsoil if the two soils have contrasting textures.
Clayey topsoil over sandy subsoil is a particularly poor combination, as water may creep along
the junction between the soil layers, causing the topsoil to slough. Sandy topsoil over a clay
subsoil is equally as likely to fail.
5. If topsoil and subsoil are not properly bonded, water will not infiltrate the soil profile evenly and
it will be difficult to establish vegetation. Topsoiling of steep slopes should be discouraged unless
good bonding of soils can be achieved.
Specifications
Mnteri sk,
Field exploration of the site shall be made to determine if there is sufficient surface soil of good quality to
justify stripping. Topsoil shall be friable and loamy (loam, sandy loam, silt loam, sandy clay loam, clay
loam). It shall be free of debris, trash, stumps, rocks, roots, and noxious weeds, and shall give evidence of
being able to support healthy vegetation. It shall contain no substance that is potentially toxic to plant
growth.
In areas where revegetation is of concern based on existing soil conditions and determined by the MVP
Environmental Inspector (EI), topsoil samples shall be taken for analysis. Samples will be collected by
the MVP EI and sent to a recognized laboratory for analysis of the following criteria:
Organic matter content shall be not less than 1.5% by weight.
pH range shall be from 6.0-7.5. If pH is less than 6.0, lime shall be added in accordance with soil
test results or in accordance with the recommendations of the vegetative establishment practice
being used.
Soluble salts shall not exceed 500 ppm.
Soil samples collected and sent for analysis will be identified by the MVP Constructions Spread # and
pipeline station from which the sample was obtained. Areas that fail to revegetate following restoration
will be sampled and analyzed based on the above parameters.

Topsoil lmporting
Topsoil would be imported as needed in residential areas only. if additional off-site topsoil is needed, it
must meet the standards stated above.
Stripping.
Topsoil operations should not be performed when the soil is wet or frozen. Stripping shall be confined to
the immediate construction area. A 4 -to 6 -inch stripping depth is common, but depth may vary depending
on the particular soil. All perimeter dikes, basins, and other sediment controls shall he in place prior to
stripping.
Stockpiling
Topsoil shall be stockpiled in such a manner that natural drainage is not obstructed and no off-site
sediment damage shall result. Stabilize or protect stockpiles in accordance with MS #2.
Excavated subsoil shall be stockpiled separately from topsoil.
Side slopes of the stockpile shall not exceed 2:1.
Perimeter controls must be placed around the stockpile immediately; seeding of stockpiles shall be
completed within 7 days of the formation of the stockpile, in accordance with Std. & Spec. 3.3 1,
TEMPORARY SEEDING if it is to remain donnant for longer than 14 days (refer to MS # 1 and MS #2).
Site Preparation Prior to and Maintenance During Topsoiling and Excavation
Before topsoiling or excavation, establish needed erosion and sediment control practices such as
diversions, grade stabilization structures, berms, dikes, level spreaders, waterways, sediment basins, etc.
These practices must be maintained during topsoiling and excavation.
Gradin . Previously established grades on the areas to be topsoiled shall be maintained according to the
approved plan.
Liming: Where the pH of the subsoil is 6.0 or less, or the soil is composed of heavy clays, agricultural
limestone shall be spread in accordance with the soil test or the vegetative establishment practice being
used.
Bonding: After the areas to be topsoilcd have been brought to grade, and immediately prior to dumping
and spreading the topsoil, the subgrade shalt be loosened by disking or scarifying to a depth of at least 4-6
inches to ensure bonding of the topsoil and subsoil. Refer to 2.8.3 Soil Compaction Mitigation within the
Project Standards and Specifications for additional inforination,
Apnlving Topsoil
Topsoil shall not be placed while in a frozen or muddy condition, when topsoil or subgrade is excessively
wet, or in a condition that may otherwise be detrimental to proper grading or seeding. The topsoil shall be
uniformly distributed to a minimum compacted depth of 2 inches on 3:1 or steeper slopes and 4 inches on
flatter slopes or to mimic existing conditions present in the adjacent undisturbed areas. (See Table 3.30-A
to determine volume of topsoil required for application to various depths). Any irregularities in the
surface, resulting from topsoiling or other operations, shall be corrected in order to prevent the formation
of depressions or water pockets.
