Bioretention Operation and Maintenance Agreement KVAI-D
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important operation and maintenance procedures:
- Immediately after the bioretention cell is established, the plants will be watered
twice weekly if needed until the plants become established (commonly six
weeks).
- Snow, mulch or any other material will NEVER be piled on the surface of the
bioretention cell.
- Heavy equipment will NEVER be driven over the bioretention cell.
- Special care will be taken to prevent sediment from entering the bioretention cell.
- Once a year, a soil test of the soil media will be conducted.
After the bioretention cell is established, I will inspect it once a month and within 24
hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal
County). Records of operation and maintenance will be kept in a known set location
and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

1. Project Background
The proposed project for the JT Russell Intermodal Ethanol Facility (Project) is located south and west of
the intersection of NC Highway 8 and the High-Point-Thomasville-Denton Railroad near Bringle Ferry
Road in Davidson County. The Project site is comprised of approximately 50 acres (Davidson County PIN
#0902800000006) located near the town of Healing Springs, North Carolina (35.61322°, -80.17758°)
within the Yadkin-Pee Dee River Sub-Basin 03-07-08. The Project drains immediately to Lick Creek
before entering Tuckertown Reservoir.
The Project entails the construction of a unit-train railroad yard composed of four (4) parallel tracks and
rail ladder, ethanol transfer facilities (i.e. pumps and piping), and two - 2.5 million gallon ethanol
storage tanks adjacent to the existing JT Russell liquid asphalt emulsion terminal facility. Ethanol is pure
alcohol that has been denatured with gasoline up to 2.5% of its total volume. Plan Sheet P-1 provides an
overview of the site layout and proposed Project.
2. Regulatory Compliance
The Project requires various environmental permitting including compliance with Water Supply
Watershed regulations, Spill Prevention, Control, and Countermeasures (SPCC) Rule, and Division of
Water Quality (DWQ) 401 Water Quality certification as it pertains to this review and BMP design. The
Project involves the development of 17.3 acres of undisturbed land resulting in 42.2% imperviousness
however, the overall parcel is much less impervious (approximately 17%). Due to its location in the
Tuckertown Reservoir watershed, it is subject to the WSW-IV ordinance administered by Davidson
County's Planning Department; the project is located in the "protected" portion of the watershed. As
such, the Project does not exceed high density thresholds of 24% built upon area (BUA) and therefore is
not required to provide any engineered storm water controls for water quality protection. However, it is
anticipated that 401 Water Quality certification will require a Storm Water Management Plan and
subsequent engineered storm water controls for compliance. The low density classification per Storm
Water Conditions in General Certifications 3819 and 3821 states:
• All storm water from the site must be transported primarily via vegetated conveyances
designed in accordance with the most recent version of the NC DWQ Storm water BMP
Manual.
• The project must not include a storm water collection system (such as piped conveyances) as
defined in NCAC 213.0202.
This Project includes multiple instances of storm water collection systems that not only provide site
drainage but must also be maintained for spill control subject to the SPCC Rule; therefore, it anticipated
that engineered structural controls may be required to satisfy the high density requirements of the 401
Water Quality certification. High density areas are required to be treated by Best Management Practices
(BMPs) that are designed to remove 85% total suspended solids. Compliance with the SPCC is required
due to the above ground storage of an oil product in excess of 1,320 gallons.
The rail yard, tank farm, and truck loading areas are designed with storm water drainage systems
consisting of inlets, pipes, underdrains, and outlets. The rail yard and tank farm have drainage systems
that also double as spill containment systems. Spill containment systems are systems that are sized to
collect a potential spill and prevent discharge to navigable waters prior to clean up efforts. This is
typically done by maintaining a closed valve on the system drainage/discharge pipe. As a result of
maintaining a closed value, periodically storm water will collect in the system and need to be manually
discharged after an inspection has been performed to ensure it's not contaminated.
The rail yard is required to also provide water quality treatment (i.e. 85% reduction of total suspended
solids) given the extensive proposed impervious area to remain after construction. The truck loading
area does not have spill potential but will need to comply with the 85% reduction of total suspended
solids as well.
The tank farm, consisting of an earthen ring levee and vegetated, compacted clay linear will have
primarily a very passive use with respect to pollutant generation. Given this semi-pervious land cover,
the passive use, and the requirement to inspect and manually release storm water from the system,
DWQ staff has granted an exemption to fully treating the storm water. It is anticipated that the limited
pollutants in the storm water would settle out before being manually released. In addition, a level
spreader and filter strip have been planned for and designed to treat any resulting pollutants in the
manual storm water discharges from the tank farm.
3. Water Quality Treatment Strategy
As previously discussed, the rail yard and truck loading areas are required to have structural BMPs to
provide an 85% reduction in total suspended solids. The total proposed BUA for the Project is 7.3 acres
across 11 unique sub-basins. Four (4) new outfalls will be created as a result of the Project and two (2)
existing drainage areas and outfalls will have new BUA proposed within their limits. The Project is being
served by six (6) BMPs. The six (6) BMPs will treat storm water from 4.5 acres of proposed BUA and 0.6
acres of existing BUA previously untreated. The existing BUA was developed prior to water quality
regulations. The BMPs treat a total of 5.1 acres of BUA; the remaining 2.2 acres, which exist in the Tank
Farm sub-basin have been exempted by DWQ staff as previously discussed. The six (6) BMPs include four
(4) sand filters and two (2) grass vegetated bioretention basins. The following table and accompanying
Project drainage plan summarizes this information.

4. BMP Design Modifications
The following design modifications are being requested as variance from the North Carolina Division of
Water Quality Stormwater Best Management Practices Manual. A reason for the variance is also
provided.
1. All sand filters have been oversized in order to accommodate potential ethanol spill volumes
with hydrologic flows in excess of typical water quality recommended values. This results in a
maximum head of less than two (2) feet. While the Manual makes no mention of a minimum
value, the Sand Filter Design Supplement form remarks that this is an insufficient depth. We
respectfully request this variance to comply with SPCC requirements.
2. A portion of all sand filters will receive flow overland from the BUA without passing through a
sedimentation basin. This portion is limited to %: the width of the outer yard tracks (1 and 4) for
the length of the sand filter. It is anticipated that the ballast dissipates significantly the overland
flows prior to discharging into the sand filter. In addition, there is approximately nine (9) feet of
3:1 vegetated bank slope to further dissipate energy and filter storm water. We respectfully
request this variance due to site limitations of the rail yard, in particular the requirement to
maintain level grades which limit the ability to drain over long distances.
3. All sand filters are designed without flow splitters in order to prevent accidental diversion of a
potential ethanol spill volume. Sedimentation basins have been adequately sized and designed
to dissipate higher flow volumes prior to discharging to the sand filters. We respectfully request
this variance to comply with SPCC requirements
4. All sand filters underdrains are designed with a maximum slope allowed by the site which does
not meet the recommended 0.5%. The underdrain's tie elevation is limited by the elevation of
the 48" culvert which runs under the rain yard. Attempting to maintain the underdrain slope
would force a higher fill for the rail yard, which would subsequently create a longer stream and
floodplain impact already proposed for the Project. In addition, the sand filters will have manual
release values that will dictate drawdown durations more so than underdrain slopes. We
respectfully request this variance due to site limitations of the rail yard, in particular the
requirement to maintain level grades and an attempt to minimize stream and floodplain
impacts.
5. Geotechnical/Soil Report
A Geotechnical Report was prepared by Bunnell-Lammons Engineering, Inc for Chambers Engineering,
PA in June 2011. As part of this report geotechnical investigation was performed for the site. The full
report is included in this submittal.
As part of the geotechnical investigation soil borings were performed at 23 locations across the site
including areas in proximity to the proposed six BMPs. Boring depths ranged from 6 -18.5 feet deep and
in no boring hole was ground water encountered during the boring process and up to a period 24 hours
after boring completion. It is anticipated that ground water elevations will not impact operation of any
of the six proposed BMPs.
Soil profiles consist of clayey soils near the surface underlain by sandy silts and silty sands. These soils
depths gradually transition into partially weathered rock underlain by bedrock formations. All proposed
BMPs are designed to be underdrained to provide complete drawdown and there is no specification to
use onsite material for the construction of filter media.

Dear Mr Chambers:
Bunnell-Lammons Engineering, Inc. (BLE) is pleased to present this report of geotechnical
exploration for the proposed Ethanol Storage and Transfer Facility Our services were provided in
accordance with Bunnell-Lammons Engineering (BLE) Proposal No. P11-0186A dated April 25,
2011 and authorized by you on April 27, 2011
The purpose of this exploration was to determine general subsurface conditions and provide
recommendations for foundation design for the proposed facility This report describes the work
performed, and presents the results obtained, along with our geotechnical recommendations.
Project Information
Project information was obtained from a conversation between Mr Stephen Chambers, P.E. and
our Mr. Gary Weekley, P.E., along with a site layout with locations for 23 exploratory soil test
borings. We were also provided with the proposed grading plan. The site is located near the
intersection of Bringle Ferry Road and NC Highway 8 in Healing Springs, North Carolina (reference
Figure 1).
We understand that the project will consist of the construction of four railroad spur lines from the

Field Exploration
June 3, 2011
BLE Project No: JI1- 7563-01
The exploration consisted of performing a total of 23 soil test borings. The soil test borings were
advanced to depths of between 6 and 18.5 feet below the existing ground surface at the approximate
locations shown on Figure 2. The soil test borings were performed using a truck-mounted drill rig
turning 2-1/4 inch I.D. hollow-stem augers. Soil samples were obtained in accordance with ASTM
D 1586 by driving a 1-3/8 inch I.D. split-spoon sampler with a 140-pound safety hammer
The ground surface elevations at the boring locations were interpolated from the elevation
contours shown on the provided drawing. The boring locations and elevations referenced in this
report and shown on the figures and field records should be considered approximate. The Soil
Test Boring Records and a description of our field procedures are attached.
Site and Subsurface Conditions
Area GeoloQy
The site is located in the Carolina Slate Belt section of the Piedmont Physiographic Province of North
Carolina. The Slate Belt is a band of rock stretching from Georgia through the Carolinas into
Virginia. The rocks are primarily volcanic and sedimentary in origin, and have been subjected to heat
and pressure (metamorphism) over geologic time since their formation. The major rock type of the
belt is not slate, but includes a variety of metavolcanic and metasedimentary rocks. The
metavolcanics include tuffs, rhyolitic, dacitic, and andesitic flows and breccias; the metasediments
include slate and argillite.
The typical residual soil profile consists of clayey soils near the surface, where soil weathering is
more advanced, underlain by sandy silts and silty sands. The boundary between soil and rock is not
sharply defined. A transitional zone termed "partially weathered rock" is normally found overlying
the parent bedrock. Partially weathered rock is defined, for engineering purposes, as residual
material with standard penetration resistances in excess of 100 blows per foot. Weathering is
facilitated by fractures, joints, and the presence of less resistant rock types. Consequently, the profile
of the partially weathered rock and hard rock is quite irregular and erratic, even over short horizontal
distances. Also, it is not unusual to find lenses and boulders of hard rock and zones of partially
weathered rock within the soil mantle, well above the general bedrock level.
Site Conditions
The project site is located just south of the intersection of Bringle Ferry Road and NC Highway 8
in Healing Springs, North Carolina. The site is bounded to the north by the mainline of the High
Point, Thomasville and Denton Railroad and to the south by Lick Creek. The site currently has a
rail spur, several tanks and buildings in the eastern half of the site. The site is mostly open fields
with scattered trees except for the wooded area in the western half of the proposed railroad spurs.

The ground surface in the vicinity of borings B-3 and B-4 was stained by ponded water Lick
Creek flows along the southern side of the site and the mainline of the railroad extends along the
northern site boundary A small stream flows through a pipe culvert beneath the railroad and
across the proposed rail spur area before draining into Lick Creek. A 400-foot diameter settling
pond is located south of the site between the proposed rail spurs and Lick Creek.
The ground surface slopes down primarily from north to south. Ground surface elevations vary
from approximately 608 to 582 feet.
Subsurface Conditions
The borings encountered 4 to 6 inches of topsoil or root mat in the open fields and wooded areas.
Borings B-21, B-22 and B-23, located in the existing facilities encountered a 6-inch thick surface
layer of gravel. Beneath the surficial materials, the borings encountered a relatively uniform
subsurface profile of firm to hard silty clay, clayey silt and sandy silt underlain by very hard
partially weathered rock (PWR). The soil overlying the PWR ranged from negligible to 12 feet in
thickness, but typically varied from 3 to 6 feet thick. The depth to the top of PWR encountered at
each boring is presented on the attached Soil Test Boring Summary The clayey soils are
moderately plastic. The PWR sampled as sandy silt and rock fragments.
Several borings encountered auger refusal at depths varying from 6 to 11 feet (approximate
elevation 572 to 589 feet). The depth to auger refusal encountered by the borings is presented on
the attached Soil Test Boring Summary Refusal may result from boulders, lenses, ledges, or layers
of relatively hard rock underlain by partially weathered rock or residual soil; refusal may also
represent the surface of relatively continuous bedrock. Core drilling procedures are required to
penetrate refusal materials and determine their character and continuity Core drilling was beyond
the scope of this exploration.
Ground water was not encountered by the borings at the time of drilling or after 24 hours.
Ground-water levels may fluctuate several feet with seasonal and rainfall variations and with
changes in the water level in the adjacent pond. Perched or trapped water may be encountered in
the soils overlying the PWR. Normally, the highest ground-water levels occur in late winter and
spring and the lowest levels occur in late summer and fall.
The above descriptions provide a general summary of the subsurface conditions encountered. The
appended test boring records contain detailed information recorded at each boring location. The
boring logs represent our interpretation of the field logs based on engineering examination of the
field samples. The lines designating the interfaces between various strata represent approximate

boundaries and the transition between strata may be gradual. It should be noted that the soil
conditions will vary between boring locations.
Foundation and Site Preparation Recommendations
Foundations for the proposed storage tanks bearing within the hard residual soil or very hard
partially weathered rock may be sized for an allowable bearing pressure of 5,000 psf, subject to the
minimum dimensions and protective embedment depths in this report. We recommend that the
minimum width for the ringwall foundation be 24 inches. The minimum width is considered
advisable to provide a margin of safety against a local or punching shear failure of the foundation
soils. Footings should bear at least 18 inches below final exterior grade for embedment needed to
develop the recommended allowable design bearing pressure and to provide frost protection.
The soil within the ring foundation of the tank will be confined by the ringwall. Under the
influence of the tank load, lateral earth pressures will be induced into the ring foundation. These
forces will be resolved as tensile forces in the ring. The ringwall foundation should be designed to
resist these forces. We recommend a coefficient of at-rest earth pressure (Ko) of 0.6 be applied to
the bearing pressure of the frill tank to estimate the lateral earth pressures on the ring foundation.
We recommend that foundation excavations be observed and the underlying bearing material
tested with a dynamic cone penetrometer by an engineering technician working under the direction
of the geotechnical engineer. This observation and testing will document that the design bearing
conditions are present and allow recommendations for any needed adjustments in foundation size
or bearing elevation to be made at specific locations.
Settlement of foundations on hard rock or the partially weathered rock should be negligible to 1/2
inch or less, respectively Additional information relative to proposed foundation loads and
additional analysis is necessary to estimate settlement of lightly loaded load bearing walls or
columns, bearing on soil. As a general statement, however, the settlements of foundations for
these lightly loaded elements would be a maximum of 1 inch, based on the above bearing pressures
for engineered fill and residual soils and our experience. The anticipated settlement should occur
rapidly following application of the load.
Individual spread foundations should bear entirely in either fill, residual soils, partially weathered
rock or hard rock. For continuous walls and slabs bearing on a combination of rock and residual
soils, overexcavation of the hard rock approximately 1 foot and replacement with compacted
aggregate or engineered fill to provide a cushion is recommended. Suitable construction joints
should be included in partition walls particularly where they span across varying supporting
materials (i.e. residual soils to partially weathered rock or hard rock).

BLE Project No. J11-7563-01
Exposure to the environment may weaken the soils at the footing bearing level if the foundation
excavations remain open for long periods of time. Therefore, we recommend that once each
footing excavation is extended to final grade that the footing be constructed as soon as possible
thereafter to minimize the potential damage to bearing soils. The foundation bearing area should
be level or benched and be free of loose soil, ponded water and debris. Foundation concrete
should not be placed on soils that have been disturbed by seepage. If the bearing soils are softened
by surface water intrusion or exposure, the softened soils must be removed from the foundation
excavation bottom immediately prior to placement of concrete. If the excavation must remain
open overnight or if rainfall becomes imminent while the bearing soils are exposed, we
recommend placement of a 2 to 4-inch thick "mud-mat" of "lean" (2000 psi) concrete on the
bearing soils before the placement of reinforcing steel for protection.
Seismic Site Classification
Based on the definitions of the International Building Code (IBC 2009) and the 2006 North
Carolina Amendments, the soil boring data, and our experience in this area, this site has a site
classification of "C" The design coefficients for seismic acceleration are as follows: for a "short"
period of 0.2 seconds, SD,, is equal to 0.209, and for a period of 1.0 seconds, SDI is equal to 0.108.
This data is based on the latitude and longitude of the facility and the "C" site classification. If
site specific seismic classification data is desired, e.g. ReMi testing, BLE should be consulted to
perform this additional testing.
Lateral Earth Pressures
Basement and retaining walls, if utilized on this project, must be capable of resisting the lateral earth
pressures that will be imposed on them. Based on testing of reasonably similar soils on other
projects, the following earth pressure coefficients are recommended. Walls which will be prevented
from rotating such as basement walls braced against the upper floor level should be designed to resist
the "at-rest" lateral earth pressure. The at-rest coefficient to be used in design will depend upon the
type of backfill used. The clayey soils encountered by the borings are not suitable for use as wall
backfill. If silty sand (sandy silt), low plasticity (PI<10) soils without clay are used for backfill
behind walls, we recommend that an at-rest coefficient (Ko) of 0.6 be used. If more granular material
such as compacted clean washed sand is used as backfill, a lower at-rest coefficient of 0.45 could be
used. In order for this coefficient to be used, the soil wedge within an angle of 45 degrees from the
base of the wall to about 2 feet below the exterior grade should be excavated and replaced with
compacted clean washed sand.

BLE Project No: J11-7563-01
Walls such as exterior retaining walls which are permitted to rotate at the top may be designed to
resist "active" lateral earth pressure. Typically, a top rotation of about 1 inch per 10 feet height of
wall is sufficient to develop active pressure conditions in soils similar to those encountered at the site.
We recommend that an active earth pressure coefficient (Ka) of 0.4 be used for design of such walls
if silty sand (sandy silt), low plasticity (PI<10) soils without clay are used for backfill. If a properly
compacted, clean washed sand is used as backfill behind the wall within the active failure zone, a
lower active earth pressure coefficient of 0.30 can be used.
The compacted mass unit weight of the backfill soil (which we estimate could reasonably be assumed
as 120 pcf) should be used with the above earth pressure coefficients to calculate lateral earth
pressures. Lateral pressure arising from surcharge loading, earthquake loading, and ground water,
should be added to the above soil earth pressures to determine the total lateral pressures which the
walls must resist. In addition, transient loads imposed on the walls by construction equipment during
backfilling should be taken into consideration during design and construction. Excessively heavy
grading equipment (that could impose temporary excessive pressures or long term excessive residual
pressures against the constructed walls) should not be allowed within about 5 feet (horizontally) of
the walls.
A coefficient of 0.5 could be reasonably assumed for evaluating ultimate frictional resistance to
sliding at the foundation-soil contact. A passive earth pressure coefficient of 2.5 could be reasonably
assumed for evaluating ultimate lateral resistance of the soil against the side of the foundation where
this is a permissible condition. This passive earth pressure should be divided by a safety factor of at
least 2 to limit the amount of lateral deformation required to mobilize the passive resistance. The
at-rest, active, and passive earth pressure coefficients presented herein are based upon the assumption
of horizontal backfill.
Sloping backfill will dramatically influence those values where walls must be designed for sloping
conditions. Bunnell-Lammons Engineering should be consulted regarding the appropriate earth
pressure coefficients if a sloping backfill condition will exist.
To reduce pore water pressures behind retaining walls, including under-slab pump station walls,
appropriate drainage should be incorporated into the wall design. This has been done in previous
projects by using a 4 to 6-inch perforated pipe along the length of the wall. Pipe should be enclosed
in NCDOT No. 57 stone, which should be placed adjacent to the wall along the entire height of the
wall. The No. 57 stone should be separated from the backfill by using a non-woven geotextile filter
such as a Mirafi 140N or approved equal to enclose the No. 57 stone envelope.

Grade Slab And Pavement Subgrade
June 3, 2011
BLE Project No: J11-7563-01
Grade slabs may be supported on an excavated residual soil smiface or on properly compacted fill. If
the subgrade consists of compacted fill, the top 18 inches of subgrade soil should be compacted to at
least 98 percent of the standard Proctor (ASTM D 698) maximum dry density for the subgrade soil.
Grade slabs should be jointed around columns and along footing supported walls so that the slab and
foundations can settle differentially without damage (unless a monolithic foundation slab is utilized).
If slab thickness permits, joints containing dowels or keys may be used in the slab to permit
movement between parts of the slab without cracking or sharp vertical displacements. A layer of
granular material should be placed immediately beneath the grade slab to provide a capillary barrier
and to increase the load distribution capabilities. We recommend that a modulus of subgrade reaction
value of 110 psi/inch or less be used for design of the grade slabs. Completed slabs should be
protected from excessive surface moisture prior to and during periods of prolonged below-freezing
temperatures to prevent subgrade freezing and resulting heave.
A site specific pavement design requires detailed information about projected traffic frequency and
intensity, acceptable service limits, life expectancy and other factors that are not currently
available. It also requires site specific laboratory testing which was not part of the scope of this
exploration. We have assumed that light-duty paved areas will be required for this project. We
define light-duty paved areas as areas having a heavy concentration of automobiles and no loaded
trucks, such as a car parking lot pavement.
Recommended pavement sections based on our experience on similar projects in this region are
presented in the following table. Assuming the site is prepared in accordance with the
recommendations of this report, the pavement sections presented as follows would be expected to
provide adequate performance considering a 15 to 20-year service life.

A proofroll test, as described in this report, should be performed on the pavement subgrade prior to
the placement of the base course. If the proofroll test is not successful a biaxial geogrid should be
placed over the subgrade to increase subgrade strength. The geogrid should be a Tensar BX1300
or approved equal which meets the requirements of NCDOT Standard Specifications Division 10.

For heavy traffic areas, we recommend adding a 3-inch thick intermediate course (type I-19.013
Superpave) to prolong pavement life.
Intermediate and surface courses of pavement constructed using the Superpave asphalt mixtures
should be placed and conform to the NCDOT Standard Specification (2006 Edition), Section 610
for type I-19 OB intermediate and 5-9.513 surface course Superpave mixtures. The base course
material should be Aggregate Base Course Material conforming to NCDOT Standard
Specification, Section 520, for Type B aggregate. The base course should be compacted to at least
98 percent of the modified Proctor (ASTM D 1557) maximum dry density. A prime coat (NCDOT
Standard Specification, Item 600) is recommended to be applied to the base course prior to
construction of the asphalt intermediate course. A tack coat (NCDOT Standard Specification, Item
605) should be applied to the intermediate course prior to the placement of the asphalt surface
course.
The concrete for rigid pavement should be air-entrained and have a minimum flexural strength
(third point loading) of 550 psi which could likely be achieved by a concrete mix having a
compressive strength of at least 4,000 psi at 28 days.
Recommended air contents from the Portland Cement Association (PCA) are as follows:
Maximum Aggregate Size Percent Air
1 %2 inches 5 percent plus or minus 1 %2 percent
% to 1 inch 6 percent plus or minus 1 %2 percent
In addition, we recommend a maximum slump of 4 inches for the plastic concrete.
Joint spacing for this concrete thickness should be on the order of 12 to 15 feet. Control points
should be sawed as soon as the cut can be made, without raveling (aggregate pulling out of the
concrete matrix) or cracks forming ahead of the saw blade. Joints should be sawed consecutively
to allow all of the joints to work together The American Association of State Highway and
Transportation Officials (AASHTO) suggests that transverse contraction joints should be one
quarter of the slab thickness and longitudinal joints should be one third of the slab thickness. All
joints should be filled with flexible joint filler
Curing of the concrete slab should begin as soon as the slab has been finished and the joints
sawed. Moist curing by fog spray nozzles or wet burlap is the most dependable curing procedure.
Other methods of curing could consist of spray applied curing compounds or covering the slab
with waterproof paper or heavy plastic. If paper or plastic is used for curing, the edges of the
cover should be anchored and joints between sheets should be taped or sealed.

Related civil design factors such as subgrade drainage, shoulder support, cross-sectional
configurations, surface elevations, and environmental factors which will significantly affect the
service life must be included in the preparation of the construction drawings and specifications.
Normal periodic maintenance will be required.
Proofrollina
After stripping and rough excavation grading, we recommend that areas to provide support for fill
areas, foundations, floor slab and pavement area be carefully inspected for loose surficial soils and
proofrolled with a 20 to 25-ton, four-wheeled, rubber-tired roller or similar approved equipment. The
proofroller should make at least four passes over each location, with the last two passes perpendicular
to the first two. Any areas which wave, rut, or deflect excessively and continue to do so after several
passes of the proofroller should be excavated to firmer soils. The excavated areas should be
backfilled in thin lifts with suitable compacted fill materials as recommended in this report.
Proofrolling and excavating operations should be monitored by an experienced engineering
technician working under the direction of the geotechnical engineer Proofrolling should not be
performed during or immediately after periods of precipitation.
Difficult Excavation
As stated previously, there is usually no sharp distinction between soil and rock in residual soil areas
such as at this site. Typically, the degree of weathering simply decreases with increasing depth until
sound rock is eventually reached. The partially weathered rock, as well as the soil above, may also
contain boulders, lenses, or ledges of hard rock. Some of the partially weathered rock of the
transitional zone could be penetrated by the mechanical auger used in this exploration and can
sometimes be excavated without blasting. However, it is often extremely difficult to excavate
partially weathered rock without blasting, especially in confined excavations such as utility trenches
and footings. The ease of excavation depends on the quality of grading equipment, skill of the
equipment operators, and geologic structure of the material itself such as the direction of bedding,
planes of weakness, and spacing between discontinuities. Weathered rock or rock that cannot be
penetrated by the mechanical auger will normally require blasting to loosen it for removal.
Corrosion Potential
There are several measurable soil properties which may be used to estimate the potential
corrosiveness of a soil. These properties include resistivity, pH, Redox potential, and sulfide content.
Resistivity and pH are the two soil properties which have the greatest influence on underground
corrosion.

The pH of a soil is a measure of the hydrogen-ion concentration and indicates the intensity of acidity
or alkalinity of a soil. A pH value of 7 indicates neutral conditions; higher values, alkalinity; lower
values, acidity Soil pH values were determined by using ASTM D4972. This test procedure
involves immersing the probe of a pH meter into a prepared slurry of soil sample and deionized water
as well as a prepared slurry of soil sample and calcium chloride solution. Both solutions are used in
order to bracket the range of pH values for a given soil with the water solution providing a higher pH
and the calcium chloride solution having a lower pH. The pH meter was calibrated with buffer
solutions prior to making actual measurements. The pH was measured for a composite of soil from
boring B-18 from 1 to 5 feet below the ground surface and a composite of borings B-21 and B-23
from 1 to 2.5 feet below ground surface. The pH values for the water-soil slurry varied from 4.5 to
5.7 for the boring B-18 sample and borings B-21/B-23 composite sample, respectively
The electrical resistivity of a soil is measured in the laboratory by immersing the probe of a
conductivity meter into a prepared slurry of soil sample and deionized water. The electrical
resistivity depends mainly on the quantity of soil water and concentration of ions in solution. The
electrical resistivity is the inverse of the conductivity Resistivity values ranged from approximately
10,900 ohm-cm to 23,400 ohm-cm for composite sample from borings B-21B-23 and boring B-18,
respectively
Using the measured lab resistivity and pH values for the soil from borings B-18, B-21, and B-23, we
estimate that the site soils to be highly-corrosive due to the low pH and resistivity Based on the
literature, a severe degree of chemical attack will occur against concrete and steel. The literature
recommends that Type V cement be used. As a less expensive alternative, potential sulfate attack
may be reduced by using a Type II cement in conjunction with an admixture such as flyash. Flyash
tends to make the concrete more dense and thus reduce the potential for corrosion. The flyash should
not be used as a substitute for cement, but as an additional part of the mix.

Engineered Fill
Fill used for the replacement of excavated unsuitable soil or for raising site grades should be
uniformly compacted in thin lifts to at least 98 percent of the standard Proctor maximum dry density
(ASTM D 698). The structural fill should contain no more than 3 percent organic matter by weight
and should be free of roots, limbs, other deleterious material and rocks larger than 6-inches in
diameter.
The moisture content of the compacted soil fill should be maintained within plus or minus 3 percent
of the optimum moisture content as determined from the standard Proctor compaction test during
placement and compaction. This provision may require the contractor to dry soils during periods of
wet weather or to wet soils during dry periods.
Before filling operations begin, representative samples of each proposed fill material should be
collected and tested to determine the compaction and classification characteristics. The maximum
dry density and optimum moisture content should be determined. Once compaction begins, a
sufficient number of density tests should be performed by an experienced engineering technician
working under the direction of the BLE geotechnical engineer to measure the degree of compaction
being obtained.
The surface of compacted subgrade soils can deteriorate and lose its support capabilities when
exposed to environmental changes and construction activity Deterioration can occur in the form of
freezing, formation of erosion gullies, extreme drying, and exposure for a long period of time or
rutting by construction traffic. We recommend that the surfaces of floor slab and pavement
subgrades that have deteriorated or softened be recompacted prior to construction of the floor slab or
pavement. Additionally, any excavations through the subgrade soils (such as utility trenches) should
be properly backfilIed in compacted lifts. Recompaction of subgrade surfaces and compaction of
backfill should be checked with a sufficient number of density tests to determine if adequate
compaction is being achieved.
Specification Review
It is recommended that Bunnell-Lammons Engineering be provided the opportunity to make a general
review of the foundation and earthwork plans and specifications prepared from the recommendations
presented in this report. We would then suggest any modifications so that our recommendations are
properly interpreted and implemented.

Basis of Recommendations
Our evaluation of foundation support conditions has been based on our understanding of the project
information and data obtained in our exploration as well as our experience on similar projects. The
general subsurface conditions utilized in our foundation evaluation have been based on interpolation
of the subsurface data between the widely spaced borings. Subsurface conditions between the
borings will differ If the project information is incorrect or the structure location (horizontal or
vertical) and/or dimensions are changed, please contact us so that our recommendations can be
reviewed. The discovery of any site or subsurface conditions during construction which deviate from
the data obtained in this exploration should be reported to us for our evaluation. The assessment of
site environmental conditions for presence of pollutants in the soil, rock and ground water of the site
was beyond the scope of this exploration.

FIELD EXPLORATION PROCEDURES
SOIL TEST BORINGS
The borings were made by mechanically twisting a continuous flight steel auger into the soil. Soil
sampling and penetration testing were performed in general accordance with ASTM D 1586. At
assigned intervals, soil samples were obtained with a standard 1.4-inch I. D., 2-inch O. D., split-tube
sampler. The sampler was first seated 6 inches to penetrate any loose cuttings, and then driven an
additional 12 inches with blows of a 140-pound hammer falling 30 inches. The number of hammer
blows required to drive the sampler the final 12 inches was recorded and is designated the
"penetration resistance." The penetration resistance, when properly evaluated, is an index to the
strength of the soil and foundation supporting capability.
Representative portions of the soil samples, thus obtained, were placed in glass jars and transported
to the laboratory. In the laboratory, the samples were examined by a geotechnical engineer to verify
the field classifications of the driller. Boring Records are attached, showing the soil descriptions
and penetration resistances.
