SOIL �ISTICS OF THE SUBJECT SITE
Soil characteristics on the site are as follows:
Charlton and Canton Soils - This series of soils consists of well -drained, non -stony to extremely stony soils that formed in sandy glacial till and loamy
glacial till. Both Canton and Chc-)rlton soils are on hills, ridges and plains of glacial till uplands, with slopes ranging from 3 -35%. The Solum series is
18 - 36 inches thick. Rock froginents make up up to 35% of the soil above a depth of 40 inches and up to 45% of the soil below that depth. As
such, they represent a high-quality.- base product for the operation proposed for the Soneco/Northeastern, Inc. site.
Sutton Soils - The Sutton series consists of moderately well -drained, non -stony to extremely stony soils that formed in loamy glacial till. Sutton soils
ore on upland hills, ridges and till plains. Slopes in this series range from 0-
8%. Sutton soils are in a drainage sequence on the landscape with
well -drained Charlton soils and poorly -drained Leicester soils. The Solum is 20 - 36 inches thick. Rock fragments make up 5 - 357. of the soil. The
C horizon is dominated by fine sandy loam, sandy loom or their gravelly analogues. As such, these soils represent a valuable base product for the
applicant's bituminous concrete operation currently existing on the site.
Udorthent Soils - Udorthents consist of excessively -drained to moderately well -drained soils on glacial till, upland hills, ridges, till ploins, drumlins and
outwash plains and on stream terraces. They are in areas where more than two feet of the upper part of the original soil has been removed or in
areas that have been covered by more than two feet of fill material. In the instant case, many areas of the site consist of Udorthent soils due to the
previous excavation and material processing operations which were conducted on the site in the post. Udorthents are in loamy or sandy glacial till and
gravelly or very gravelly outwash. Slopes range from 0 - 15%. Udorthents are found in conjunction with well -drained Canton and Chorlton sails mid
moderately well-droined Sutton and Woodbridge soils. Coarse fragments range from 0 - 65% in the soil. These sails represent a valuable base material
for utilization in the applicant's comprehensive earth product and bituminous concrete operations planned for the site.
Charlton -Hollis Soils - This series consists of well -drained to somewhat excessively well -drained nor -stony to extremely stony soils that formed in loamy
glacial till. These soils are on upland hills, ridges and plains of glacial till uplands. Slopes range from 3 -45%. Charlton -Hollis soils are in a drainage
sequence on the landscape with moderately well -drained Sutton soils and poorly -drained Leicester soils. The Solum ranges from 10 - 36 inches thick
and rock fragments make up 2 -- 35% of the soil above a depth of 40 inches. Rock fragments make up 5 - 45% of the soil below that depth. As
such, these products represent a high-quality base material for the applicant's proposed earth product processing operation on the site,
Woodbridge Soils - The Woodbridy series consists of moderately well -drained non -stony to extremely stony soils that formed in compact, loamy glacial
till. Woodbridge soils are onDrurnlodial upland landforms. Slopes range from 0 - 15%. The Solum in the Woodbridge series is 22 - 38 inches thick.
-
Rock fragments make up 5 35`1 of the Solum and 10 - 40% of the Cx horizon. Woodbridge soils contain high-grade base material for the
applicant's proposed earth product processing operation.
Wetland Soils - All wetland activities in conjunction with the proposed earth products excavation and processing operation can the applicant's property were
conducted under the permit issued on August 3, 1995. The applicant is not proposing any regulated activities or any construction activities in regulated
areas in conjunction with the instant special permit application.
Open Water Bodies - The open water body within Phase I of the proposed excavation operation consists of a pond which was created circa 1955 for
utilization for wash water and sedimentation containment in conjunction with a former earth product processing operation on this site. The pond consists
of approximately 1.7 acres. The pond has on overage length of 500 feet and an average width of 220 feet. There is a finger of man made uplands
which extends in a southeasterly to northwesterly direction for nearly the whole length of the pond. This man made berm is approximately 30 feet in
width.
FILTER BARRIER INSTALLATION & MAINTENANCE
1. Dig a 6" trench on the uphill side of the barrier location.
2. Position the posts on the downhill side of the barrier and drive the post 1.5' into the ground.
3. Lay the bottom 6" of the fabric in the trench to prevent undermining and backfill.
4. Inspect and repair barrier after heavy rainfall.
5. Sediment deposits are to be removed when they reach a height of 1' behind the barrier and
are to be deposited in an area which is not regulated by the Inland Wetlands Commission.
6. Inspections and necessary repairs will be made twice -weekly.
HAY BALE INSTALLATIO I & MAINTENANCE
1. Bates shall be placed around all proposed catch basins with the ends of the bales tightly abutting each other.
2. Each bale shall be securely anchored with at least 2 stakes and gaps between bales shall be wedged with straw to Dre'<er' h c from passing
between the bales.
3. Inspect bales after each storm and repair or replace promptly as needed. Remove sediment behind the bales when is hcs - _.c half the height of
the bale and deposit in an area which is not regulated by the Inland Wetlands Commission.
4. Inspections and necessary repairs. will be made twice -weekly.
PERMANENT VEGETATINECOVER
Topsoil will be replaced once the excavation has been completed and the shoulders are graded to a slope
no greater than 3 to 1. Topsoil will be spread
at a minimum compacted depth of
4 inches. Once the topsoil has been spread, all stones two inches or
larger in any dimension will be removed as well
as debris. Apply agricultural ground
limestone at the rate of two tons per acre or 100 lbs. per 1000 s.f.
Apply 10-10-10 fertilizer or equivalent at a
rate of 300 lbs. per acre or 7.5 lbs. per 1000 s.f. Work lime and fertilizer into the soil to

1, An anti -tracking pad constructed in accordance with the detail thereof on the Site Plan has been constructed at the southeasterly limits of the 30 -foot
access road to the earth product excavation site. The anti -tracking pad has been designed in a location which will result in the removal of excess material from
truck tires as the trucks enter the existing poved area to the northwest of the existing bituminous concrete asphalt plant. The onti-tracking pad is constructed
in a location which will result in maximum protection in order to prohibit earth product materials from being conveyed both onto the existing operational area of
the applicant's site and Caroline Rood.
2. The applicant has installed and is maintaining Phase I erosion and sediment control devices as delineated on the December 15, 2000 site plan prepared by
Chandler, Palmer & King, as previously approved by the Montville Planning and Zoning Commission, and in accordance with this Narrative and the periodic review
recommendations
of the Town of Montville Zoning Enforcement Officer. The sediment ponds as delineated on the prior site plan have been fully developed and
are operational. During the course of earth product processing operations in conjunction with this application, the sediment ponds will be cleaned with an
excavator on a weekly basis while earth product processing operations are in effect. The supply pond shall be cleaned on an "as needed" basis. All sediments
removed from the sediment pond on a weekly basis will be removed to the dewatering area delineated on the site plan and stored until dewatered. Thereafter,
said materials shall either be utilized in the applicant's operations or land filled in the silt cells depending upon the quality and consistency of the some.
3. The applicant will install recharge/sediment basins I -A and I -B in the area delineated on Sheet 5 of 6 of the Site Plan upon completion of the backfill of the
silt cells in the Phase I area. Said basins have been designed and will be constructed in order to accomplish the following purposes: (i) as an erosion control
measure to contain the migration of sediments resulting from ongoing excavation operations on site and (ii) to provide the recharge of groundwaters in the some
hydrological pattern as has existed on site prior to the commencement of operations.
4. All vegetation in the southerly one-half of the Phase I excavation area has been clew rid and the applicant has grubbed that portion of the site and excavation
operations are currently ongoing. Topsoil stripped from the active operation area is stockpiled on the site in accordance with the Phase I operation narrative.
Said topsoil shall be retained on site for eventual use in the stabilization of the site sub equent to the completion of excavation operations in the Phase I area.
The surface soil stockpile shall be stabilized with a single row of silt fence around each •,tockpile location, Stockpiles are constructed at a slope not to exceed
3:1 and are stabilized by seeding with a Perennial Rye Gross mix and mulch.
5. The 30 -foot wide access road providing access to excavation areas within Phase I hay; been constructed substantially in accordance with the prior site plan.
The 50 linear foot 18 -inch HDPE cross -culvert pipe representing an emergency overflow spill4vay from the recharge/sediment basin designated by the 390 contour
as delineated on Sheet 5 of 6 of the Site Plan, in order to provide an outlet for overflow eminating from said recharge/sedimentation basin which may occur
during design storms from the contributing drainage area, will be installed as delineated on Sheet 5 of 6 of the site plan upon completion of construction of the
sedimentation/recharge basins. Inlet and outlet protection will be installed at the inlet and outlet of said cross -culvert in accordance with the riprap data table
contained on Sheet D-1 of the prior Soneco Service, Inc. site plan. The surface of the 30 -foot wide access road has been stabilized by installing and
compacting a bankrun gravel surface thereon of sufficient depth to provide a stable road base for truck traffic which will be utilized in the conduct of the
excavation operation. During the dry months, calcium chloride and/or watering shall be provided to the gravel surface to provide dust control as required.
6. The existing outlet pipe from the proposed sedimentation and water supply pond to a former supply pond located at the easterly extreme of the Tilcon
Connecticut, Inc. site has been excavated 75 feet easterly from the wetlands limits of the supply pond in order to access the existing pipe. The pipe has been
cut and capped to prevent any future interconnection between the working sedimentation and supply pond and the former supply pond located at the easterly
extreme of the site.
7. Excavation operations in the Phase I operation area have been en ongoing for approximately sixteen years. The applicant has excavated both sur -ficial material
and stone in the southerly portion of the Phase I excavation area. That excavation and the earth products processing associated therewith has demonstrated that
there is an excessive amount of fines in the soils excavated on the site. In order to provide a marketable product, it is necessary to extract the fines from the
finished product through the washing operation, However, this has resulted in approximately 30-35% of the excavated surficial material on the site being
maintained as an unusable waste product.
As delineated in the Project Narrative Modification submitted to the Montville Planning and Zoning Commission in April, 1995, the volume of waste material
generated when coupled with the additional waste material which will be generated by ongoing opera -:ions will require a more sophisticated method of disposition in
order to ensure that this byproduct can be adequately controlled and that sedimentation damage does not occur as a result of operations on the Tilcon
Connecticut, Inc, site. As a result of that analysis, a quarried cell storage technique was developed by the applicant's predecessor in title whereby cells have
been blasted into the bedrock in the southerly portion of the Phase I area and rock material extracted therefrom. Thereafter, the cells have been backfilled with
the non market grade earth product material in order to achieve the final grading plan as delineated on the Site Plan, The increase in rock composition created
from the disposition of the blasted material which is a byproduct of the cell construction wilt also allow the applicant to utilize less overburden in its commercial
operations; thereby reducing the amount of silt generated from ongoing operations.
Upon completion of excavation operations in the southerly one-half of the Phase I excavation area, including the cell construction, the applicant shall utilize the
operating cell for the remaining duration of the project in order to provide a silt disposal orea for the silt which will be generated from the excavation of surficial
material in the northerly portion of the Phase I excavation area and In the Phase 11 and Phase III excavation areas. The size of the cell(s) shall be modified in
order to provide sufficient storage to accommodate the silt disposal which will be necessitated by the Phase II and Phase III excavation operations. Upon
achieving finished grades in the Phose I excavation area, as delineated on Sheet 5 of 6 of the Plan, the Phase I excavation area, other than that portion of the
operating cell which will continue to be utilized for silt disposal generated by the Phase II and Phase III excavation operations, shall be loomed with not less than
four inches of loam obtained from the temporary surface soil stockpile. Areas to be seeded will be prepared by spreading ground limestone equivalent to 507,
calcium plus magnesium oxide at a rate of 1 00 pounds per 1,000 square feet. Fertilizer (10 -IC -10) is to be applied at a rate of 15 pounds per 1,000 square
feet, Following the initial application of lime and fertilizer, there are to be no q
periodic applications of lime and fertilizer, After seeding, the areas shall be
stabilized with hay mulch immediately applied at a rate of 70 -- 90 pounds per- 1,000 square feet and anchored immediately after spreading by tracking.
Seeding shall be applied with a mix of Kentucky Blue Gross applied at 20 pounds per acre. Creez)ing Red Fescue applied at 10 pounds per acre and Perennial
Rye Grass applied at 20 pounds per acre for a total of 50 pounds per acre. Seeding sha i be between April 1 and June 15 and August 15 to September 30,
8. Upon completion of excavation in the southerly, one-half of 'the Phase I excavation area, the applicant and/or his contractor shall commence excavation
operations in the northerly one-half of the Phase I excavation area. Excavation operations anc the stab' 'zotion of all remainingdisturbed areas of the
Phase I
excavation area shall be conducted in accordance with the requirements set forth in Parogroph 7 of the Construction Sequencing section of this Narrative. In the
event that additional storage area is required for silt disposal, cell construction can continue i --o the northerly ane -half of the Phase I excavation area.

excavation area, all top soil shall be stripped from the site and stored within the project limits. Said topsoil shall be retained on si,e for eventual use in
the
stabilization of the site subsequent to the completion of excavation operations in the Phase II area. The applicant or hiis contractor shall push the surface soil
fromh
t e exterior limits of the operating area of the Phase II excavation operation to the stockpile locations so that all excavation operations will proceed inward
from the exterior boundaries of the limits of the Phase II excavation. The surface soil stockpiles shall be stabilized by installing a single row of silt fence around
each stockpile location. The stockpiles shall be constructed at a slope not to exceed 3:1 and shall be stabilized by seeding with a Perennial Rye Grass mix and
mulch, The Perennial Rye Grass mix shall be applied at a rate of 40 pounds per acre. Mulch shall be applied at the rate of 80 pounds per 1,000 square feet
and shall be spread by hand or with a mulch blower.
2. The proposed 30 -foot wide access road providing access to excavation areas within Phase 11 of the excavation operation shall be constructed in conjunction
withh n - - - -
t e construction of recharge/sediment basins II -A, II B, II C, II D and II -E and in conjunction with the site plan. Overflow connections shall be constructed
between recharge/sediment basins II -A and 11-13, II -B and II -C and II -D, the purposed riprap channel and II -E in occordance with Sheet 4 of 6 of the Site Plan.
a .
All such recharge/sediment basins shall be a minimum of two feet in depth. The sedimentation basins shall be designed by the applicant's engineer to
accommodate anticipated sedimentation for the de-vegetoted area as determined in accordance with the United States Soil Conversation Service Handbook. The
sizing of said sedimentation basins has been determined by the prior applicant's engineer as contained in a document entitled "Soil Loss Analysis For Sizing Of
Groundwater Recharge/Sediment Basins Proposed Gravel Operation Prepared For Soneco Service, Inc. Caroline Rd. Montville, Ct. July 1993" prepared by Total
Technology, Inc. Each such groundwater recharge/sediment basin has been designed to allow said structures to retain stormwater resulting from a minimum
25 -year design storm. Said recharge/sediment basins together with the overflow connections appurtenant thereto shall be constructed in accordance with the
details delineated on Sheet 5 of the prior Soneco Service, Inc. site plan. The riprap channel shall be constructed in accordance with the detail thereof delineated
on Sheet 5 of the prior Soneco Service, Inc. site plan. Velocity within the riprap channel shall be controlled by the installation of stone check dams within the
channel in accordance with the details delineated on Sheet 5 of the prior Soneco Service, Inc, site plan. The velocity control stone check dams shall be installed
at such locations as the applicant's engineer determines are necessary to control velocity within the riprap channel to insure that no erosion occurs. During
operations, the Zoning Enforcement Officer of the Town of Montville shall have the power to direct the applicant to install additional velocity control stone check
dams in the event that the stone check dams designed by the ciippi'cont s engineer are insufficient to control erosion within the riprop channel. In constructing
the 30 -foot wide access road, the applicant or his contractor shall install a 50 -foot long 1$ -inch HDPE cross -culvert under the 30 -foot proposed access road
at a slope of 0.04, The surface of the 30 -foot wide access road shall be stabilized by installing and compacting a bankrun gravel surface thereon of sufficient
depth to provide a stable road base for truck traffic which will be utilized in the conduct of the excavation operation. During the dry months, calcium chloride
and/or watering shall be provided for the grovel surface to provide dust control as required.
