MOORESVILLE REGIONAL OFFICE
The purpose of this letter is to inform you on our progress in
addressing deficiencies identified at our Midland, NC, facility by the
North Carolina Division of Water Resources (NCDWR) per NOD-2018-
PC-OWL2.
On February 16, 2018, Linde LLC (Linde) sent you a letter to
communicate our investigation and improvement plan in response to
NOD-2018-PC-0012. In our response, we identified as one of our actions
to engage a cooling tower treatment service contractor for the purposes
of developing cooling tower chemistry to improve the control of
chlorine level in the cooling tower and to properly add a dechlorination
chemical additive to the cooling tower blow down prior to discharging
to the facility's retention pond.
Nalco Water (Nalco) was engaged for the above described purpose and
has developed an updated cooling tower treatment plan to actively

control our cooling tower chemistry, which has been implemented. The
plan also includes a continuous monitoring and alarm system.
Therefore, we take this opportunity to notify you of our revised current
cooling tower chemistry:
• Dechlorination chemical additive - Nalco 7408 (sodium bisulfite)
• Corrosion Inhibitor - Nalco 3DT230
• Biocide - Nalco Stabrex St70
• Algaecide - Nalco 9005
Note that the planned changes in chemistry were discussed via
telephone conversation with Mr. Roberto L. Scheller on March 13, 2018.
Finally, in addition to the above, we have maintained our retention
pond to restore its original retention volume.
With the above actions, Linde believes that we are adequately
addressing the deficiencies identified in NOD-2018-PC-0012.
We look forward to continue working with NCDWR in making this
improvements to our wastewater discharge. If you have any questions
or concerns, please contact meat 704-322-7537.

MOORESVILL.i=. REGIONAL OFFICE
Linde, LLC (Linde) is pleased to present a summary of the recent
investigation of the potential Total Residual Chlorine (TRC) exceedances
documented in the North Carolina Department of Environmental
Quality (NCDEQ) letter dated November 20, 2017 for the Linde facility
located at 3537 Fieldstone Trace, Midland, North Carolina. This letter
also is the follow up to the NCDEQ'Notice of Deficiency'; dated January
20, 2018 / Tracking Number: NOD-2018-PC-0012.
Background
On November 20, 2017, Linde notified NCDEQ of potential exceedances
pertaining to TRC. The 24 hour notification was done verbally to Mr.
Pitner on November 15, 2017. As part of the investigation, Linde hired
ERM, Inc. (ERM) to conduct an investigation into the potential TRC
exceedances.
Field Activities
On December 14, 2017, ERM personnel conducted a site visit to review
the site conditions at the site as well as mark the proposed sampling
locations.

ERM mobilized on December 27, 2017 to collect the grab water samples
(Retention Pond Discharge Before, Retention Pond Discharge After,
Compressor blowdown, cooling tower blowdown, Muddy Creek
downstream and Muddy Creek upstream) before and after the blow
down.
The grab water samples were analysed for:
• Total Residual Chlorine (TRC) using Method SM 4500-CL E
• pH using Method EPA 9045C
• Temperature using Method SM 2250B-2010
• Oil and grease using Method EPA 1664A
• Chemical Oxygen Demand using Method SM 5520D
Results and Conclusions
The grab water samples indicated the following TRC values which
exceed the permit conditions for TRC: -- - -
• Sample Retention Pond Discharge After = 380 ug/L
• Sample Cooling tower blowdown =130 ug/L
• Sample Muddy Creek downstream =150 ug/L
• Sample Muddy Creek upstream =100 ug/L
Based on the above results, Linde believes the source of the residual
chlorine is cooling tower blowdown and will work with our cooling
tower chemistry and operation contractor, Nalco, to improve the
performance of the exiting dechlorination chemical additive, ChemTreat
BL-1240 to the treatment system prior to discharging to the retention
pond. We may choose to change the cooling tower chemistry at this time
and will advise NCDEQ if any changes are planned.
We look forward to working with NCDEQ in making this improvements
to our wastewater discharge. If you have any questions, or if we can
provide further assistance, please contact us at 704-322-7637.

Q Coleen H. Sullins, Director
Division of Water Quality
May 1, 2008
To: NPDES Permittees
Subject:ect1ie0 ug/1,Cornpliarice ieuk33
In a previous letter dated August 14, 2001, the Division of Water Quality (DWQ) notified
NPDES permittees that water/wastewater ,treatment facilities with Total Residual Chlorine
(TRC) effluent limits would be required to use analytical methods that produce detection levels
below their permit limit by July 1, 2002. [Note: TRC permit limits are typically set between 17
to 28 ug/l for discharge to freshwater systems, and 13 ug/l for discharge to saltwater systems].
This requirement was based on an Environmental Protection Agency (EPA) audit of the NC
enforcement program. It was also necessary to ensure water quality protection and compliance
with state monitoring regulations [15A NCAC 2B.0505(e)(4)].
Since that time, DWQ has received several inquiries regarding difficulties with the new
analytical methods, primarily focused on 1) lack of precision with field instrumentation at low
TRC levels for both water and wastewater treatment plants; and 2) manganese interference with
TRC measurement at several water treatment plants. Some facilities have overcome these
problems through various changes, such as: 1) switching dechlorination chemicals; 2) adding a
.second dechlorination feed; 3) changing analytical methods; 4) incorporating manganese
correction; 5) switching to LTV disinfection; 6) removing sludge from water treatment plant
settling basins. Also, the DWQ Laboratory Certification staff have provided extensive field
assistance for the new lab methods. Still, some analytical issues remain. In response to the
permittee's concerns, the Division is providing the following changes to its TRC requirements:
p TRC Compliance Level Changed to 50 ug/l. DWQ continued discussions with EPA
regarding analytical difficulties with TRC measurements, and in March 2008 received
EPA approval to allow a 50 ug/l TRC compliance level. This will not change the
analysis, annual verification of meter performance, or data reporting, but simply how the
reported values will be evaluated by DWQ. from a compliance standpoint. Facilities will
still be required to report actual results on their monthly DMR submittals, but for
compliance purposes all TRC values below 50 ug/l will be treated as zero. For example,
if the facility has a TRC limit of 17 ug/l and reports a TRC value of 40 ug/l on the DMR,
this value will be considered compliant under this new policy. This new compliance
level is effective March 1, 2008 (beginning with March 2008 DMR submittals).
DWQ will continue to incorporate TRC effluent limitations into NPDES permits for all
water/wastewater treatment facilities that discharge chlorine -bearing wastestreams to surface
waters. While this new TRC compliance level of 50 ug/l is effective beginning March 1, 2008, it
Will be incorporated into existing NPDES permits with. TRC effluent limits upon permit renewal.,
At that time, the following TRC footnote language will added to the Effluent Limitations Sheet:
"The facility shall report all effluent TRC values reported by a NC certified laboratory including
field certified. However, effluent values below 50 ug/l will be treated as zero for compliance
purposes."

Generator failure. Water treatment using bleach and inhibitors has been used since to
control biological activity. The effluent flows into a stormwater basin (containing two
stormwater outfalls) prior to discharging into an adjacent stormwater drainage ditch.

To Whom It May Concern:

APR 15 2013
IUIOCtRE ,E PL'L�. sR Caii�NAL OFFICE
To follow-up on the reporting of a permit exceedance for the Linde LLC facility in Midland, NC, the following is a summary
of the investigation and plans for further sampling.
13 Semi-annual sample, taken March 21, 2013, results were reported by phone due to total residual chlorine
exceedance - 0.16 mg/I, permit limit is the lowest detection limit of the testing method, 0.05 mg/I.
13 Sodium hypochlorite is used to maintain normal cooling tower operations and contributes chlorine to the
discharge. Waste water discharges to an on -site pond with a retention time of 4 days. Chlorine breaks down
very rapidly in the water and there is not concern that health or the environment is negatively impacted.
The permit requires testing of the water at the discharge to the pond and not the out flow of the pond.
Discharge resampled on April 4, 2013. Site received the results on April 8, 2013. The lab found the level of
total residual chlorine leaving the cooling tower and going to the pond to be 0.04 mg/I. These results show
compliance with the permit limit.
Tower operations have been reviewed and no abnormalities were found. Sodium hypochlorite usage has
resumed. The next semi-annual test is scheduled for September 2013.
Further evaluation of sampling will be completed and new results reported. If there are any questions or if further
information is needed, please do not hesitate to contact me.

Enclosed is a Notice of Renewal Intent application (original and two copies) for the BOC Gases facility located at
3537 Fieldstone Trace, Midland, NC 28107. The existing Certificate of Coverage number is NCG500604. The
facility discharges non -contact cooling water, condensation, and storm water to an on -site detention pond and
then to Muddy Creek. The storm water discharge falls under the "exempt storm water" definition as all rain water
flows to the pond designed for cooling water.
For chemicals used as inhibitors in the Cooling Tower, MSDSs are enclosed as well as sent under separate cover to
the Aquatic Toxicology Unit. Ozone gas is created and dissolved in a side stream of cooling water and fed into the
tower at three points for use as a biocide. It is fed 8 to 12 hours per day to achieve a concentration of about 0.2
ppm ozone. A Biocide works heet was not completed for ozone.
Please feel free to contact me with any questions or the Plant Manager, Howard Schultz, at 704-888-3884.

PART IV - EVALUATION AND RECOMMENDATIONS
The applicant has requested approval to discharge non -contact cooling water and
condensate from the manufacturing of industrial gases at a site near Midland, NC. Domestic
wastewater and truck wash water, which will also be generated at this facility, will be sent to the
WSACC's Muddy Creek WWTP. Biocidal additives will be used in the cooling water with
approval from the Aquatic Toxicity Unit necessary prior to permit issuance. The discharge will
enter a small, earthen pond prior to discharging to the receiving stream. This pond will also
collect SW from other areas of the company's property.
Pending final technical review and approval by the NPDES Unit, it is recommended that
an NPDES General Permit be issued as requested.

Dear Permittee:
The facility listed above is covered under NPDES General Permit NCG500000. NCG500000 expires
on July 3.1, 2007. Federal (40 CFR 122.41).and North; Carolina (15A NCAC 2H.0105(e)) regulations require
that permit renewal applications must be filed at least 180 days prior to expiration of the current permit: If
you have already mailed a renewal request, you may disregard this notice.
To satisfy this requirement, the Division must receive a renewal request postmarked no later than
February 1, 2007. Failure to. request renewal by this date may result in a civil penalty assessment. Larger
penalties may be assessed depending upon the delinquency of the request. This renewal notice is being sent
well in advance of the due, date so that you,have adequate time to prepare your application.
If any discharge previously covered under NCG500000-will occur after July 31, 2007, the
CoC must be renewed. Discharge of wastewater without a valid permit would violate North Carolina
General Statute 143-215.1; unpermitted discharges of wastewater may be assessed civil penalties of up to
$25,000 per day.
If all discharge has ceased at your facility and you wish to rescind this CoC [or if you have other
questions], contact meat the telephone number or e-mail address listed below.

Mr_ Colby:
The Water and Sewer Authority of Cabarrus County (WSACC) will not accept discharge
into our Muddy Creek Wastewater Treatment Plant from cooling tower blow down water
from the proposed BOC Process Plant in Midland, North Carolina. There are two reasons
for this denial:
1. The proposed discharge does not meet the requirements in Section 2.1(b)(14) of
WSACC's Sewer Use Ordinance (relevant sections attached).
2. The discharge volume of approximately 31,000 gallons per day (gpd) would
consume 41% of the capacity of the Muddy Creek Wastewater Treatment Plant,
which has a capacity of 75,000 gpd.
If you have any questions, please call me at [phone].

OUR PROJECT NUMBER 8433-NC
Dear Mr. Colby:
Subsurface Engineering, P.C. has completed the authorized geotechnical
investigation and engineering evaluation for the proposed liquefied gas
production plant to be built on a pre -graded site.
In summary, our investigation indicates that the soils encountered at the site are
capable of adequately supporting the proposed construction on shallow spread
footing foundations if the site preparation and design recommendations
presented in this report are implemented. This site has been previously filled,
thus is variable in areas from hard slate to structural fill.
Due to the shallow depths to be affected by the proposed construction, rock
excavation difficulties should be minimal in the top six (6) feet.
Based on the data obtained in the soil test borings, we anticipate that minimal
groundwater control problems will be encountered during the construction
operations. Several areas have groundwater from three (3) to six (6) feet of the
surface.

substation at the approximate locations shown on the attached Test Boring
Location Plan. The borings were drilled to depths of ten (10) to twenty (20) feet
below existing grade. Boring locations were determined in the field by distances
measured from existing structures or power lines. '
Soil split -spoon sampling and penetration testing were performed in accordance
with ASTM Standard D-1586. The Test Boring Records show detailed soil
descriptions and stratifications, consistency evaluations, standard penetration
resistances (N), boring termination depths, and groundwater conditions at each
boring location.
LABORATORY INVESTIGATION:
Laboratory investigative work consisted of a visual examination and classification
of the disturbed samples obtained during our field operations. Our foundation
type and bearing pressure recommendations are based on an evaluation of the
soil and rock types encountered .at this site in conjunction with the Standard
Penetration Resistances obtained in the Test Borings.

SITE AND SURFACE CONDITIONS
SITE LOCATION AND DESCRIPTION:
Th-a-pla-nrred-1Tgcrefied-gas plant -is located-ir -Midiand,-North-Ca-rotina. This area -
is characterized with rolling hills drained by wet weather'and permanent streams.
SURFACE CONDITIONS:
The plant site lies within the Slate Belt Physiographic Province of North Carolina.
In this province, the parent bedrock has weathered in place to form the silts and
clays which comprise the mantle of residual soil encountered at this site. The
most severe weathering has occurred at the original ground surface where the
soils contain a greater percentage of fine-grained particles. This strata is
generally a clayey silt, with depth, there is a transition to fine sandy silt then the
parent slate.
A generalized description of the site soils below the ground surface follows.
1. A 4-inch thick sand and gravel road is located at the ground surface at
several areas. A thin surface veneer of grass and topsoil is located in
other areas. This previously graded site has grown up in grass or weed
with a root zone. This is called topsoil due to the grass root organics.
2. Existing soil fill three (3) to six (6) feet deep is present below the surface
veneer at B-13, B-14, B-16 and B-17. This fill is texturally a clayey silt or
sandy silt, and contains slate rock fragments from the parent rock.
Consistencies range from stiff to very stiff. In the past, the base of the fill
has been proofrolled. Intermittent density tests are attached. This fill is of
structural quality.
This fill area represents a former low depression between two (2) hills.
The area was cleared, grubbed and stripped. The base was proofrolled
and fill from the adjacent higher ground was placed and rolled.
This results in a variable site cross section. The cut areas have the upper
soil profile removed and the slate rock strata is at or near the surface. At
a lower level, the soil profile is thinner only having part of the soil
A

SUtsSUKFAGE ENGINttKINU, F.U.
PROJECT NUMBER 8433-NC
removed. In the bottom or lower portions of the fill, the soil profile is
thicker over the parent slate rock.
3. A water_ deposited, or alluvial, soil may have been present below the
existing fill, but has been removed in the site undercut or proofroll.
4. Weathered -in -place, or residual, soil is present below the existing fill.
Texturally, this residual strata is a silt, clay or fine sandy silt with
consistencies ranging from soft to very hard.
With depth, there is a rapid transition to fine sandy silts. This soil has a
firm to very hard consistency that increases rapidly with depth. The
exception is in the area of Test Boring B-5 where the soil becomes soft
with depth.
In machine foundation areas, Test Borings B-7 and B-8, there is a very
stiff surface crust several feet thick over a stiff strata. With depth, the very
stiff consistency returns.
This stiff strata will not be of uniform thickness or at a horizontal depth,
thus may be present in the footing excavations. A lower design soil
bearing pressure in Table 1 is recommended to overcome this condition.
5. Partially weathered rock was encountered at 15 of 19 Test Borings at
depths of 0.3 to 14 feet below present grade, respectively. Table 1
summarizes these depths at each Test Boring. This partially weathered
rock is arbitrarily defined as residual soil with a standard penetration
resistance of 100 blows/foot.
6. Auger refusal was met at seven (7) Test Borings 8.5 to 12.5 feet below
grade. This strata was not diamond cored to determine its nature or
continuity, but is projected to represent boulders or bedrock.
Characteristically, the slate belt rock is closely jointed and slabby. It
weathers into soil at a slow rate and more resistant rock fragments remain
in the soil mix.
Areas previously cut for borrow have shallow slate depths. Thus areas by
the garage may have rock at the surface.

r'MVJr_%' 1 IYUIYIOGll O'tJJ_19V
GROUNDWATER:
Groundwater was encountered at 4 to 7.5 feet below existing grade at Test
Borings B-1, B-2, B-5, B-6 and B-8. Some groundwater or perched condensate
_ - ----- - --- -
water adjoins the in -place process tank pad.
These levels were measured during a period of seasonally dry weather and may
be high due to drainage of plant condensate. Groundwater levels are projected
to fluctuate 3 to 5 feet with seasonal moisture variations. The levels measured
represent the seasonal low of late summer/early fall.
The fine grained fill or residual soil is slow to drain and holds moisture. When
the moisture does percolate the deeper slate belt rock with clay, filled seams will
hold the water.
Excavations dug and not drained or refilled will hold water and soften the base
soils after time.
A summary of the groundwater data is given in Table 1.
Detailed soil descriptions, stratifications, and consistency evaluations, as well as
termination depths and groundwater conditions at each boring location are
present on the Test Boring Records in the Appendix.

PROPOSED CONSTRUCTION
The planned construction, as we understand it, will consist of a one (I) -story,
pre-engineered garage and control room. The -floor Slab will- be on grade or on a
structural fill six_(6) to twelve (12) inches above grade. These column loads are
projected at 30 to 50 Kips.
The industrial equipment will consist of pumps, motors and compressors. The
loads will be high speed rotating machines with a massive concrete base to
resist rocking or start up torque.
Tanks will be flat bottom, ground supported or supported on a grillage above
concrete pad on the ground. An air gap for thermal control may be provided.
Tank loads are estimated at 1000 to 1500 psf.
The substation will consist of ground supported transformers and switch
equipment. Loads are projected at 1000 to 1500 psf.

PROJECT NUMBER 8433-NC
EVALUATIONS, CONCLUSIONS, AND RECOMMENDATIONS
The evaluations, conclusions, and recommendations presented are based on
-- -
our understanding of the proposed site development and construction, the data
obtained from -the T-est_Borings,-our_engineering-analy-sis,-a-Rd our--ax arience with soils and subsurface conditions similar to those encountered at this site.
SITE PREPARATION:
Initial preparation of all area to provide support for the proposed buildings,
equipment and substations should consist of the following:
1. All organic matter, such as topsoil or root systems should be removed
from an area extending at least 5 feet beyond the perimeter of proposed
building, paved areas, and any areas where structural fill will be placed.
2. Existing plans of the construction area should be consulted and the site
should be inspected to locate existing underground utilities, such as
electrical and telephone cables, which may serve the existing adjacent
structures. If such utilities are found in the proposed construction area,
they should be removed, relocated, or protected.
3. The working area should be graded so that surface runoff will drain away
from the construction locations by gravity. Preparation of the existing
surface in this manner will minimize the possibility of a reduction in the soil
bearing capabilities due to saturation from standing water. The standing
water ponds should be drained. Diversion swales should keep off site
runoff away from the project area. If required, building pads, tanks, scales
or pumps should be raised slightly above the adjacent grade.
The fine grained clayey silt and silt soils will soften when exposed to water
or freeze thaw seasonal behavior. These soils will be hard to dry in the
winter months. Site grading for winter construction should be done prior
to Thanksgiving, if possible.
4. To densify areas of weak surface soils, we recommend that the existing
ground surface in all construction areas, including the cleared area which
extends 5 feet beyond the perimeters of building and paved areas, be
10

PROJECT NUMBER 8433-NC
proof rolled with a heavily loaded, pneumatic -tired vehicle such as a
rubber -tired roller, loaded dump truck or pan. This vehicle should have a
minimum static weight of 20 tons and should be operated at a speed
approximating that of a slow walk (one to two miles per hour).
5-- T e­pT of-roll-rstTouid-make at-le-ast-four-passes-over-the site-with-tre— --
last two passes perpendicular to the first two. Any areas which wave or
deflect excessively and continue to do so after several passes of the proof
roller should be undercut to firm soils and backfilled with new structural fill
(see Structural Fill).
STRUCTURAL FILL:
After the site preparation operations are completed, the site may.then be graded
to the subgrade elevation.
In order to achieve high density structural fill with minimum compressibility, the
following steps are recommended in all fill placed at this site:
1. Laboratory Proctor density tests should be performed on representative
samples of each different type of soil to be used for fill to provide the data
necessary for quality control. The existing structural fill appears clean and
free of excessive organics. However, any areas wet of optimum moisture
will require drying of the existing fill. This will take time in the colder
months due to the fine grained fill.
2. Suitable fill material should be placed in thin, nearly horizontal lifts (lift
thickness depends on type of compaction equipment, but generally lifts of
8 inches loose measurement are recommended). The lifts should be
compacted mechanically with construction equipment such as a vibratory
sheepsfoot roller. Proof rolling the fill surface with a heavily loaded,
rubber -tired vehicle will be desirable to help seal the surface and inhibit
potential water absorption during periods of rain. The sealing operation is
particularly important at the end of the workday and at the end of the
week.
3. We recommend that (a) structural fill soils to support the foundation be
compacted to a minimum of 95% of the Standard proctor Maximum Dry
Density (ASTM D-698), and (b) the upper 12 inches of structural fill
11

ZOUMZWKI-AGt CNU1NtCK11vu, rA
PROJECT NUMBER 8433-NC
directly beneath floor slabs and 24 inches directly beneath paved areas
be compacted to 100% of the Standard Proctor Maximum Dry Density at
optimum moisture ±2%.
4. Structural fill should be 'extended beyond the outside footing perimeter of
the structure minimum horizontal distance equal to 2 times the ep h__of f 1
beneath the nearest footing, plus 5 feet. This will result in a 5-foot
horizontal "buffer" of structural fill outside the perimeter of the exterior
footings and 2 horizontal to 1 vertical fill slopes. A flatter 3 horizontal:1
vertical exposed fill slope will be needed for grassing. '
5. An experienced engineering technician, working under engineering
review, should take adequate density tests throughout the fill placement
operations to verify that the specified compaction is being achieved. It is
particularly important that this be accomplished during the initial states of
the filling operation so that adjustments in the compactive effort, number
of passes, or compaction equipment used can be made early in the fill
program.
FLOOR SLAB SUPPORT:
The floor slab will support relatively light loads of 100 to 150 psf. This floor slab
will perform satisfactorily when supported on structural fill if the following steps
are completed:
1. Initial preparation of floor slab area is completed as outlined in the Site
Preparation section of this report. The slate belt rock and silt soils have
minimal shrink swell behavior. The more plastic clayey silts have limited
shrink swell behavior.
2. Structural fill is placed in the floor slab area in accordance with the
recommendations presented in the Structural Fill section of this report.
3. The floor slab is jointed and constructed separate from wall partitions and
foundations so that the structural frame and floor slab will move
independently of each other. An alternate is to provide a turned -down
slab at the building perimeter. Reinforcing steel is recommended.
12

rMUJCL.1 NUIVIOCR o'►JJ`1YV
FOUNDATION DESIGN:
We recommend that the design soil bearing pressures given in Table 1 be used
to size all footings to support the spread footings, unless a footing with
--- _ - - - .......---- ---- - -._ --.._:__ . - -----
dimensions smaller than that recommended -below will result. This
_____ — r_eco-mmended_beadng pressure is based on total live and dead structural loads for footing design. In addition, we recommend minimum dimensions of 16 inches
for strip footings and 24 inches for isolated rectangular spread footings. Lightly
loaded, non -load bearing interior partitions may be supported on thickened floor
slabs. Footings should bear at least 18 inches below the finished exterior grade
so that adequate cover for frost protection and against a bearing capacity failure
are provided.
The site soil support conditions are variable between fills and slate rock. Table 1
has reduced these variable bearing pressures to a lower pressure that will
extend over a larger area. In some sites, the marked increase in consistency
with depth has a deeper, higher design soil bearing pressure.
Based on our review, total settlements of 1 /2 to 3/4 inch are estimated with the
recommended design soil bearing pressure, residual and structural fill soils, and
100% of the total live and dead loads. Since only a percentage of the total live
loads will actually be exerted 100% of the time, the estimated total settlement will
be less than 3/4 inch. Total settlements of less than 3/4 inch, based on our
experience, should be satisfactory for this- building and substation support.
Heavy, high speed motors or compressors may have special bearing and
settlement restrictions.
DRAINAGE:
Since groundwater is present at the site within a depth of three (3) to six (6) feet,
a drain is not required beneath buried tanks to continuously remove
groundwater. A vapor barrier consisting of a minimum 6-mil plastic sheet is
recommended beneath the floor slab.

NKUJLU I NUMt$tK t$4JJ-Nl;
EXCAVATION CONDITIONS:
Due to the presence of hard and very dense soils and partially weathered rock at
shallow depths at this site, we anticipate that localized difficulties will be
encountered when removing these materials to prepare confined excavations for
- --utility-line-footings,-or-site grading. -Inmost _site-areas,_d-epth_ s _of four-( )- to_six
(6) feet should be in hard soil. The slate rock is knobby and in areas of previous
cuts near the garage, it may be at the ground surface.
Heavy ripping, mechanical splitting in pre -drilled holes or demolitioh hammer
may be required for removal without blasting. Slate is not a hard or blocky rock
type but thinly bedded which may help in its removal with heavy ripping.

PAVEMENT:
The parking area will be subject to primarily auto traffic with tractor trailers in the
garage and diesel fuel areas.

Maintain positive drainage or road side ditches. Proofroll road subgrade.
Undercut clayey silt in truck areas two (2) foot and replace with weathered slate
rock as structural fill compacted to 100% Standard Proctor maximum dry density.
The following pavement cross -sections are provided based on an estimated
California Bearing Ratio (CBR) of 5 for saturated silt or clayey silt soils. Materials
and methods of the pavement components should conform to the North Carolina
Department of Transportation Standard Specifications for Roads and Structures.

In truck fuel areas, a 10 inch thick concrete pad with 3000 psi concrete and
temperature steel will be needed. This is a truck terminal type paving for
repetitive heavy wheel load.
CORROSION
These fills of residual soils and the residual soils are weathered from generally
acidic rocks, thus are slightly acidic. Concrete cover of three (3) inches will
provide alkali conditions to protect footing steel.
High density polyethylene pipe or concrete pipe may be used for storm sewers
and will have longer life than corrugated galvanized pipes.

ADDITIONAL SERVICES RECOMMENDED
Additional soil and foundation engineering, testing, and consulting services
.. ........ - - recommended for- this project -are summarized le ow. The recommendations
----- --- presented -in this-r-porgy a -re -contingent -upon the-inspec-tion--program-outkned.
1. PROOF ROLLING INSPECTION: We recommend that and experienced
soil engineering technician, working under the direction of an engineer,
witness the proof rolling operations prior to fill placement so,that he is
available to assist the contractor in delineating any soils which require
removal and replacement with suitable and properly compacted structural
fill.
2. QUALITY CONTROL OF FILL PLACEMENT: An experienced soil
engineering technician, working under the direction of an engineer, should
witness all required filling operations and take sufficient in -place density
test to verify that the specified fill compaction is achieved. He should
observe and approve borrow materials being used and determine if their
existing moisture contents are suitable for use to achieve the required
degrees of compaction.
3. INSPECTION OF BEARING SURFACES: We recommend that the
bearing surfaces of the footing excavations be inspected by a qualified
soil engineering technician. This inspection is recommended to verify
design soil bearing pressures and define those areas where materials of
variable bearing soils are encountered.
4. PAVEMENT SYSTEM INSPECTION: The pavement sub -base, base
coarse, and asphaltic materials should be inspected and tested during
preparation and placement to insure that project specifications are being
followed.
