Part IV MCC Building Schematics
Part V Hunter Mesa Evaporation Pit Special Use Permit Application Resolution
Part VI Hunter Mesa Evaporation Pit Special Use Permit Application
Part I Project Description
EnCana Oil & Gas (USA) has gained approval for construction and operation of the
Hunter Mesa Evaporation Pit (Garfield County Board of County Commissioners
Resolution Number 2003-02). Subsequent design work for the facility has identified the
need for additional structures within the facility boundaries. The first of these is a suction
tower in the treated water pond, with an accompanying pedestrian bridge. The second
additional structure is a motor control center (MCC) building. Refer to the Site Plan in
Part II of these application materials for a representation of the planned locations of these
structures.
The suction tower and pedestrian access bridge planned for the treated water pond has
been designed to enhance facility operation and to make maintenance activities safer and
easier for facility personnel. Refer to the schematics in Part III for details on the design
of these structures. These structures are static structures planned to be an integral part of
the finished facility. As such, they will have the same general characteristics as other
permanent structures at the site, in terms use and hours of operation. These structures
will generate no noise or dust and will have minimal visual impact in relation to other
structures at the site.
The MCC building planned for the facility has been designed to enclose electrical
controls and circuit breaker panels. The operation of the facility is dependant upon
electric power and proper control of electrically powered systems. The MCC will protect
the control systems from weather and corrosion as well as providing additional safety to
facility personnel by providing a common, sheltered location for these systems. The size
of the building is 16 feet by 30 feet and the location is shown on the Site Map in Part II.
Refer to the schematics in Part IV for details on the design of the MCC building. The
building is a static structure planned to be an integral part of the finished facility. As
such, it will have the same general characteristics as other permanent structures at the
site, in terms use and hours of operation. The MCC building will generate no noise or
dust and will have minimal visual impact in relation to other structures at the site. An
application for a building permit for the MCC building will be submitted to the Garfield
County Building and Planning Department upon approval of this Special Use Permit.
Refer to the previous Special Use Permit for the Hunter Mesa Evaporation Pit in Part VI
of these application materials for information regarding the location, purpose, planned
use, and characteristics of the facility and the associated systems.

PROJECT DESCRIPTION
HIJNTER MESA STATION
EVAPORATION PIT ADDITION
EnCana Oil and Gas (USA), Inc. (EnCana) currently operates natural gas wells in Garfield County.
These wells produce brackish water commonly referred to as produced water. This produced wateris alkaline and must be disposed of properly. ihe rate that a natural gas well generai.s produced
water is variable but historical rates have averaged approximately Z.i barrets'per day.
Produced water is also generated during the drilling and completion of a natural gas well. It issometimes necessary to truck several hundred barrels of water from a drill site uft.r.ornpletion of awell. At an individual well any oil and/or natural gas is separated from the produced water
generated by the well. The water is typically stored in an 8O-barrel capacity tank at the well location
and then intermittently loaded onto a tank truck and hauled off site.
The primary non-water component of the produced water is sodium chloride. Traces of other saltssuch as magnesium chloride and sodium bicarbonate are also present. The produced water contains
an average of 10,000 parts per million total dissolved solids. This level of salinity is beyond potabiebut still far lower than that of seawater. Produced water also contains trace amounts of free anddissolved oil.
EnCana (and formerly Snyder Oil) has operated an evaporation pit near Rifle since 1996. Thecapacity of this evaporation pit is no longer adequate. dnCana intends to construct an additional
evaporation pit next to their Hunter Mesa Booster Station south of Rifle. The Hunter Mesa facilitywill be constructed somewhat differently than the Rifle evaporation pit. The new facility will beequipped with extra measures to prevent oil from reaching th" rrup*ation pond. The off-load watertanks will be plumbed in series with internal weirs and m6st of the oil will be separated andcontained at this poill. Water discharged from the off-load tanks will then pass through a gaspowered heater in which any oil that may carry over from the tanks will be separated and contained.The heater also increases the water temperatuie thereby increasing the evaporation rate.
The majority of water that passes through the new facility will not be evaporated but will bepurified and reused in EnCana hydro fracturing operations. Approximat.ly thr"" quarters of theproduction water will exit the heater system inio a state of the art electronic water treatment
system. The electronic water treatment system will lower the Total Dissolved Solids (TDS) to wellbelow 3,0-00 parts per million (ppm) and this treated water will be stored in a separate Low TDSpond. EnCana personnel will pull water form the Low TDS pond as needed for Lydro fracturing.
The new facility would operate similarly to the existing pond where the produced water will besprayed over the pond to increase the evaporation rate. A series of center-mounted sprinklers willdistribute the water over the pond in droplets. The droplets will be small enough to maximizeevaporation while not creating a mist, which would tend to drift. The anticipat"ed total rate ofspraying is approximately500_ gallons per minute. The sprinkler lines will be charged utilizing anelectric motor powering a Berkley 3/8 pump. The pump and distribution lines will be situatedwithin the lined area so that in the event of a leak the water will be contained.

IMPACT STATEMENT
HUNTER MESA STATION
EVAPORATION PIT ADDITION
The location for the new facility was selected for a number of beneficial reasons. The proposed
location is central to Encana operations in the area. This will shorten truck trips and reduci the
number of trucks traveling closer to town The evaporation facility will not differ significantly from
the surrounding land uses, which are oil and gas reiated. The locaiion is relatively rernote. ThL
closest residence is over 1 mile southeast of the site therefore sufficient distance Lxists to prevent
noise or odor impacts to surrounding properties.
The hours of operation for the facility will be as such: the evaporation system pump and sprayerswill operate 2417 during the spring and summer months and will be purged and shut down for thefall and winter months; the electronic water treatment system and heatei treater will operate
24/7/365. The majority of water trucks will travel to and from the site between 8 am ind 4pm but
some trips may be made outside of these hours if needed.
At maximum usage the facility is expected to generate approximately 20 to 25 water tanker truck
trips per day into and out of the new facility. The majoriiy of these tiips will be on existing private
roads that already service natural gas operations on Hunter Mesa. Waier trucks will operat-e'primarily during daylight hours and will be traveling to and from well locations in the area. Heavytrucks already frequently travel the roads in the Hunter Mesa area therefore the new facility is noi
expected to require improvements to the existing roads. At present EnCana hauls produced water to
their. evaporation pit on 3 19 Road just south of Rifle, as *eil as to the Black Mountain disposalfacility in Mesa County. The new facility will reduce the number of trips to the present evaporation
facility therefore keeping the majority of EnCana related truck traffic farther from town.
During the evaporation process an estimated2percent of the spray is lost to driftage. The saline
nature of the produced water can potentially impact vegetation orsurrounding lands. The driftage
also has a noticeable odor but as long as the driftage is contained the odor is also contained. The
new facility will contain this driftage with a berm, approximately 20 feet tall and 60 feet wide at its
base, on the downwind sides of the pit. Noise will biimanated by the aeration pump and sprayers.
The containment berm will aid in mitigating this noise as well as controlling arituge. fne soundlevel of noise emanating from the facility will not exceed the 75 decibel muii-rr- set forth in
Colorado Statute 25-12-103. Given the remote location of the new facility, noise or odor will not
be a nuisance. If in the unlikely event nuisance noise or odors are emanated by the facility extra
measures will be taken to control them.
The location of the proposed Hunter Mesa facility is underlain by gravels and alluviums derivedmainly from sandstone, shale or basalt. The predominate soil type in the site area is clayey loam.
This facility is designed to protect the groundwater resources. The pits will be lined with
impermeable HDPE and if groundwater is encountered during construction, monitoring wells will
be installed and sampled regularly.
There will be no use of either groundwater or natural surface water on the facility. The facilitydesign will preclude any pollution to enter surface run-off. There will be no sewage generated onthe site. The unloading and tank area will be constructed in accordance with US EpA SpillPrevention Control and Countefineasures Plan requirements. As such, secondary containment ordiversion structures will be constructed to preveni any release from leaving the facility.
The property boundary, as depicted on the Site Layout Map, will be surrounded by g-foot tall chain-link fence' Fencing will contain two steel access gates and- cattle guards *itt U. installed at bothgates' The gates will remain open during daylighihours and will6e secured ovemight. There willalso be a2 to 3-foot tall small-mesh fenci ptaced at the base of the g-foot tall fence. The small-mesh fence will be partially buried into the ground to preclude small animals that may otherwise beable to enter through the chain-link fence. this type oifencing will be sufficient to preclude wildlifeentry' Surrounding uses are such that a visible barrier fence slould not be necessary. Signage willinclude the company name and address as well as a 24-hour toll-free emergency phone number.
The facility will occupy eight acres of rangeland considered to be winter rangeland for mule deer.This type of facility is by nature incompatible with continued wildlife access therefore wildlife willbe. excluded by wildlife-proof fencing. The limited size of the facility will notblock wildlifemigration routes. An oil separating systemwill be employed to prevlnt oil from reaching theholding pond in order to eliminatJpotential impacts to waterfowl. A waterfowl deterrent system ofhigh tensile steel wires will cover tire High tpb Pond urJ th. Frac water pond. These wires will bestrung parallel to each other at a 4-meteripu:ilg covering the ponds. rnis type of system hasnumerous benefits over traditional netting while sufficienily preventing waterfowl access.
The facility will utilize three sizes of steel above ground holding tanks. Three 40g-barrel (bbl)capacity tanks, 12 ft-in diameter by 20 ft high, wilt noto the production water offloaded from thewater trucks' Five 300 bbl capacity tanks, 12 ftindiameter by 15 ft high, *irr t
"ra water or oil fromthe heater treater separator system. one 210 bbl capacity tank, l0 ft iridiameter by 15 ft high, willcapture overflow from the other tanks. All tanks will bepainted in a beige color to match thesurrounding terrain.
A minimal amount of lighting will be required for the new facility therefore four 1 7S-wattmercuryvapor lamps will be installed. These lamps can be set to tum on automatically at dusk and turn off atsunrise' Two lamps will be mounted on the east side of the tanks in order to light the offloading areaand two lamps will be mounted on the west boundary to iigrrt tt. ponds for safety purposes. Threephase electrical power services the comp.ressor station adjicent to the proposed facility thereforeupgrades to existing electrical utilities will not b. r...r*ry.
The expected life of the Hunter Mesa Evaporation Pit is 20 years. Reclamation of the facility wouldinclude regrading the facility to the approximate existing slope, replacing stockpiled .,topsoil,, andseeding with the seed mix of the .u.r.rt rand mange.,, Jhoi...
construction of the facility is expected to take approximately 10 weeks to complete.

HEATER TREATER,
AND
ELECTRONIC WATER TREATMENT SYSTEMS
HUNTER MESA STATION
EVAPORATION PIT ADDITION
The oil skimming system will be constructed to achieve optimal oil-water separation. Each off-load
water tank will be plumbed with internal weirs allowing the oil that floats to the top to be skimmed
off and contained in a separate tank. The relatively oil-free water will be discharged from the off-
load tanks into a heat-treating system. The "heater treater" will remove remaining oil before the
water reaches the evaporation pit.
The manufacturer and model of heater treater has not yet been determined but the unit will be
constructed to industry standards. The model selection will be based on acceptable throughput
capacity while operating at the lowest possible temperature to achieve the deiired separation of
water and oil.
The electronic water treatment system is manufactured by Sabrex of Texas, Inc. This new system
will allow EnCana to recycle approximately three quarters of their produced water. Once the
produced water is treated with the Sabrex system EnCana will use the water in their hydro
fracturing operations. The Sabrex system is described on the following three pages.

Electronic Water Pu rification
For basic TDS reduction in Water and Waste Water
By Robert Atlas, Sabrex of Texas, lnc.
For years Reverse Osmosis and Dl have been used to remove total dissolved solids from water andwastewater. Today the high energy requirements, use of hazardous chemicals for cleaning andregeneration requirements, complexity of pretreatment requirements and high volumes of wasterejecUregeneration water are coming under attack by reguiatory agencies in-commercial andindustrial applications. There is also a growing requiiemEnt to recy:cte water due to NpDESpermitting restrictions or other regulatory compliance requirement-s. There is new electronic waterpurification (EWP) technology that can offer an alternative to traditional water puriflcation.
How Does it Work?
There ls no comparable technology on the market today and is marketed under the EWp brandname by Sabrex and Alamo Water Refiners. Various Dissolved salts and Silica in water are themajor components of TDS (total dissolved solids). These dissolved salts need to be removed onmany applications, or they will form deposits and affect equipment performance. (Figure 1)

Figure 3
The Electronic Water.Purifier makes patented technology available to generate Dl quality water byremoving these dissolved salts electronically.
Electrodes used are made from activated carbon fabric and a conductive material. When theseelectrodes are layered using a DC power supply, the individual electrodes are charged with differentpolarities. The dissolved salts in the water have polarity charges are attracted to th5 oppositepolarity of the electrode, thus removing the dissolveO s-alts frdm the water. These dissbived salts areadsorbed electrochemically on the activated carbon electrode surface creating the pure water.(Figure 2)
\Nhen sufficient dissol.ved salts are deposited on the electrodes and conductivity increases beyondthe set point,desired, the electrodes are regenerated by shorting the electrodesto ground. Th6

contaminants fall off the electrode in the same chemical form as was removed. After the
regeneration, the waste at 5 to 10 times the original concentration is discharged through a valve to
drain. (Figure 3) Upon completion of this cycle, the polarities are reversed for normal operation.
The principal of first order kinetics applies, since the same percentage of dissolved solids is
removed regardless of whether the feed stream is 500 PPM or 2,000 PPM. Only the run time is
affected. The llmit on TDS is 2,500 PPM with this carbon fiber based material, ln the future carbon
powder based technology is being developed that will safely operate at TDS levels of 15,000 PPM.
Pretreatment is not a major issue, since the factors that affect membranes and resin such as
suspended solids, chlorine and organics do not affect the electrodes of the EWP. Also the

electrodes do not allow bacteria to breed and colonize.
Cycle Testing
Much testing has been done on San Antonio
Water for over 1,000 cycles (Figure 4).
Consistently, based on a volumetric average
over 75o/o of the dissolved salts in the water
removed through one pass through the electrode
at 1 gpm over a duration of more than 2 hours.
The regeneration time per cycle was
Only 15 minutes. Only 1.7 watt-hours of
electricity are used per gallon of water purified.

rype cX Whir![efspray nozztes
- for spray pond applications
The water cooling efficiency of a spray pond depends, to a large
extent, on the spray nozzles used. Spraying Systems Co. type
CX- Vhirfet hollow cone spray nozzles provide the best all
around perforimance characteristics for this application. As
tabulated on Data Sheet 11798-SP and Data Sheet L4452'l rhese
\flhir[et spray nozzles provide a wide range of capecity sizes and
spray coverage characteristics. The type CX- \(rhir[et nozzles
spray good water volumes at low pressures with relatively small
droplets depending on nozzle capacity and spraying pressure.
These small droplets provide larger suspended droplet surface
areas for evaporation while driftage is kept at low levels. The
2CX-50 capacity size is frequently used for spray pond
applications.
Special slope bottom whirlchamber design reduces the drilling
effect found in other nozzlewhirlchambers ... thereby extending
nozzle wear life. This feature is especially important in spray
ponds since the recirculated spray water may contain wear
producing abrasive dust and grit particles.
No internal obstructions and larger diameter free passages
provide clog-free type performance.
Good spray pattern performance at pressures as low as 5 psi.
Usually spray pond pressures range from 5-10 psi, with 7 psi a
popular choice, thereby minimizing driftage problems.
Long lasting durable construction ... quality castings from brass,
gray iron or Type 316 Stainless Steel.
Precision machined to provide consistent flow rate, spray
coverage, droplet size and uniform spray distribution. Choice of
inlet connections: !", !-l/2", 2" or 2-l/2' NPT(F). See Data
Sheets 11798-SP and14452't (pages 53 and 55).

EXCLUSIVE PATENTED

ONE PIECE CAST ryPE
MEDIUM_LARGE CAPACIry
Standard one-piece cast lype
WhirlJet spray nozzles feature
a hollow cone spray pattern with
a ring-shaped impact area and
spray angles ol 59. to 94".
They produce a uniform distrF
bution of medium to large-sized
droplets over a wide range of
pressures and llow rates.
WhirlJet nozzles in these medium
capacity ranges produce finer
atomization than other types of
nozzles operating at the same
flow rate and pressure...thus
they are especially effectlve
where quick heat transfer or
effective airborne droplet
impingement is required.
WhirlJets also provide an impor-
tant benefit with their large and
unobslructed flow passages,
which minimize or eliminate
clogging.
C and D series WhirlJet spray
nozzles feature one-piece cast
construction with a precision-
machined finish and the original
WhirlJet whirlchamber design for
uniform spray distribution.
CX series slope bottom Whiruet
nozzles feature the same uniform
spray performance as the C and
D series...plus the added advan-
iage of the patented longer-life
slope bottom design...to reduce
the 'drilling effect" of the liquid
vortex in the whirlchamber.

EVAPORATION ESTIMATES
HUNTER MESA STATION
EVAPORATION PIT ADDITION
Industry experience indicates that use of spray aeration systems effectively double the National
Oceanic and Atmospheric Administration "pan evaporation rate", The pan evaporation rate is
estimated to be approximately 45 inches from which the average u*rul precipitation of 14 inches
must be subtracted. The net evaporation rate is therefore 31 inches. Doubling'31 inches of
evaporation yields a 62-inch evaporation rate utilizing spray aeration.
The surface area of the evaporation pit is approximately 1.8 acres, which is expected to yield an
evaporation rate of approximately 9.3 acre feet/year.9.3 acre ftlyear is equivafifi1p 72,153

lf the anchor trench is excavated in clay susceptible to desiccation, no more than the amount of
trench required for the geomembrane to be anchored in one day shall be excavated (unlbss
otherwise specified) to minimize desiccation potential of the anchor trench clay soils.
Slightly rounded comers shall be provided in the trench where the geomembrane adjoins the
trench so as to avoid sharp bends in the geomembrane. No large rocks or clay lumps shall be
allowed to underlie the geomembrane in the anchor trench.
Backfilling of the anchor trench shall be conducted in accordance with Section 3.5.
Geosvnthetic Placement
lmmediately prior to installation of the designed geomembrane liner, the surface shall be
observed by CLC and the owner or the owneds representative. The decision to repair cracks, if
any, shall be made only by the Project Manager. The subgrade shall be walked by CLC and the
Project Manager for joint approval. CLC will sign acceptance of the surface condition of the
subgrade. The integrity of the underlying soil is the responsibility of the owner/earthwork
contractor. l
Subgrade Preparation Recornmendations:
No liner shall be placed on surfaces not previously found acceptable by the CLC
supervisor or his agent.

Field Seaminq
3.3.1 Seam Layout
ln general, seams should be oriented parallel to the line of maximum slope; i.e., oriernted along,
not across, the slope. ln corners and odd-shaped geometric locations, the numbe,r of seams
should be minimized. No horizontalseam should be less than 5 feet (1.5 m) from the toe of the
slope or areas of potential stress concentrations unless otheruvise authorized. When full roll
lengths do not extend past the toe of slope, panel ends may be seamed provided the panel end
is cut at an angle gieater than 45o to minimize seam stress.
A seam numbering systern compatible with a panel numbering system shall b6 agre,ed upon at
the Pre-Construction Meeting.
3.3.1 .1 Field Joints
Field joints shall be made by overlapping adjacent sheets approximately 3 inches for
extrusion welding and 4 inches for hot wedge welding.
3.3.1.2 Pipe Sleeves
Polyethylene pipe sleeves shall be used for pipes penetrating through the lined area.
When the pipe composition is polyethylene, the sleeve should be extrusion welded
directly to the pipe if space permits. For dissimilar materials, the sleeve should be
fastened by mechanical means and sealant applied between the pipe and sleerre.
3.3.2 Seaming Equipment and Products
The approved processes for Ret seaming are extrusion welding and fusion (hot wedger) welding.
Proposed altemate processes shall be documented and submitted to the Owner or his
representative for his approval.
The extrusion welding apparatus shall be equipped with gauges giving the temperature of the
apparatus at the nozzle and extruder banel.
The fusion welding apparatus shall be equipped with gauges giving the applicable tempr=ratures.

The electric generator is placed on a smooth base such that no damage occuns to the
geomembrane;
Buffing shall be completed no more than one (1) hour prior to extrusion welding (buffirrg is not
necessary for hot wedge welding);
A smooth insulating plate or fabric is placed beneath the hot welding apparatus after use;; and
The geomembrane is protected from damage in heavily trafficked areas.
3.3.3 Seam Preparation
CLC shall verify that:
Prior to seaming, the seam area is clean and free of moisture, dust, dirt, debris of any kind, and
foreign material; and
Seams are aligned with the fewest possible numberof wrinkles and "fishmouths".
3.3.4 Weather Conditions for Seaming
The normally required weather conditions for seaming are as follows:
The high temperature limit for welding is the temperature at which the well-being of tlre crew
becomes uncertain.
Unless authorized in writing by the Project Manager, no seaming shall be attempted at iambient
temperatures below 50 Fahrenheit.
The colder the weather, the slower the welding speeds possible for effective welding. Further
detail for cold weather welding follows in this section.
ln all cases, the geomembrane shall be dry and piotected from wind.
CLC shall verify that these weather conditions are fulfilled and will advise the Project Marrager if
they are not. The Project Manager shall then decide if the installation shall be stoprped or
postponed.
Cold Weather Seamino of Polvethvlene Liners
Cold Weather welding restrictions exist because problems associated with hot air seaming
techniques have been mistakenly applied to extrusion welds. The CLC extrusion weld, however,
has been successfully employed in cold weather on several job sites. With the assistance of
preheating the sheet, the CLC weld has been applied as low as -SoF. Both the CLC extrusion
weld and hot wedge weld are able to overcome cold weather welding restrictions because of their
unique designs.

a. An over capacity heater band on the extruder.
b. An e).tra over capacity heater band on the nozzle-
c. A separate proportional temperature controller for each heater band.
d. The nozzle thermocouple positioned approximately 118 inch from the end of the nozzle
which rides on the sheet.
The CLC hot wedge welder lifts the sheet slightly to minimize the effects of subcooling from a
frozen sub-base. Temperature controls can be adjusted to guarantee fully integrated welding as
demonstrated by peel testing.
To guarantee quality welding in cold weather, the following procedures are recomnrended for
CLC welds:
The sheet should be preheated before welding any time ice crystals are present in the'weld path.
When strong winds are present, a shield of some sort should be set in place to prevent large
convection heat losses from the welding gun during seaming-
Test welds should always be prepared and tested before seaming in orderto gauge appropriate
welding conditions. (Example: Welding machine temperatures should be set higher and welding
speed reduced.)
3.3.5 Trial Seams
Trial seams shall be made on fragment pieces of geomembrane liner to verify that seaming
conditions are adequate. Such trial seams shall be made at the beginning of each seaming
period (start of day, midday, and anytime equipment is tumed off and allowed to cool down) for
each seaming apparatus used. Trial seams shall be made under the same conditions as actual
searns.
The trial seam sample shall be approximately 3 feet (1.0 m) long by 1 foot (0.3 m) vdde (after
seaming) with the seam centered lengthwise. Seam overlap shall be nominally 4 inches; 3
inches minimum.
Two adjoining specimens each'1 inch (25 mm) wide, shall be cut from the trial seam sample by
the installer. The specimens shall be tested respectively in shear and peel using a field
tensiometer, and they should not fail in the seam. lf the additional specimen fails, the entire
operation shall be repeated- lf the additional specimen fails, the seaming apparatus and seamer
shall not be accepted and shall not be used for seaming until the deficiencies are corri:cted and '
two consecutive successful trialwelds are achieved.

3.3.8 DestructiveTesting
3.3.8.1 Concept
Destructive seam tests shalt be performed at random selected locations. The purpose of
these tests is to check that welds are fully integrated with each other and tcr evaluate
seam strength. Seam strength testing shall be done as the seaming work progresses,
3.3.8.2 Location and Frequency
The owner and/or ownels representative shall select locations where seam samples will
be cut. These locations shall be established as follows:
A frequency shall be agreed upon by CLC and the Project Manager at the Flesolution
andlor Pre-Construction Meeting. Unless otherwise specified, destructive samples
should be pulled at intervals of I sample for every 500 linear feet of weld.
The seaming technician shall not Ue iniormed in advance of the locations urhere the
seam samples will be taken.
3.3.8.3 Sampling Procedure
Samples shall be cut by CLC as the seaming progresstis in order to have te:;t results
before the geomembrane is covered by another material. CLC shall:
Cut samples;
Assign a number to each sample which is to be based upon seam and sample number
and mark it accordingly;
Record sample location on daily report; and
All holes in the geomembrane resulting from destructive seam sampling s;hall be
immediately repaired in accordance with repair procedures described in Section 3.4.
The continuity of the new'seams in the repaired area shall be tested according to Section
3.3.7.
3.3.8.4 Size of Samples
At a given sampling location, two types of samples shall be taken by the lnstaller.
First, two sample coupons for field testing should be taken. Each of these sample
coupons shall be 1 inch (0.25 mm) wide by 12 inches (0.3 m) long with the seam
centered parallel to the length. The distance bettyeen these two samples shall be 42
inches.

as follows:
one portion to the lnstaller (cLC) for testing, 18 inches X 12 inches:
One portion for Geosynthetic Quality Assurance Laboratory testing if appllicable' 12
inches X 12 inches (0.3 m X 0.3 m); and
one portion to the ownerforarchive storage, 12 inchesX 12 inches (o-3 m X 0.3 m)'
Final determination of the sample sizes shall be made at the Pre-Construction Meeting.
3.3,8.5 Field Testing
The two f -inch (25 mm) wide strips, mentioned in Section 3.3.8.4, shall be tested in the
fietd for peel and sfreai and shall not fail in the seam.' lf any field test sample fails to
pass, then the procedures outlined in 3.3.8.7 shall be followed.
Etectric or hand tensiometer testing in the field is to be can'ied out. Ther following
procedure is followed: lf the initial sample coupon test passes a film tearing bond, the
sample qualifies for further testing to obtain quantitative results. lf it fails, the seam
should be repaired in accordance with Section 3'4'
Destructive Testinq of Seams:
Destructive testing of seams is very important because it provides the clnly direct
evaluation of seam strength and bonding efficiency which indicates seam durability.
Destructive testing involves two techniques: 1) shear testing, and 2) peel testing.
Shear testing appiies a tensile stress from the top sheet through the weld arrd into the
bottom sheet. Peel testing, on the other hand, peels the top sheet back against the
overlapped edge of the bottom sheet in order to observe how separation ocr:urs. The
peel test indi&tes whether or not the sheets are continuously and homogeneously
connected through the seam.

(Based on NSF 54 Standards)
Tvoe of Material ) No. of Coupons
Standard testing procedure is as follows:
lf there is a failure in either peel or shear, then flve lotal coupons are tested. lf more
than one coupon fails, then the sample fails. This is a modified ASTM method. The
ASTM methods that are used are D4437, D413 and D638 which all can apply.
Reasons for pass/fail criteria:
The FTB requirement is very important. With a fully integrated, continuous connection. through the seam, no weld bead/sheet or sheeUsheet interface exists. Such an interface
might be separated by absorbed chemicals, causing failure of the seam.
ln addition to the FTB criterion, a minimum stress level is specified. This is important in
order to protect against legitimate tearing of a thin portion of polymer in the r,veld (as
might occur if the weld is off center).
The minimum stress levels are necessarily lower than tensile yield strength:; of the
parent sheet because of the different configuration of the test specimens; during' destructive testing. Bending momentb come into play along with straight tensile
stresses, especially as the sheets are bent back in peel. These bending moments.. depend on the shape of the welds which vary even within the same welding teclhnique.
The minimum stress values are based on the average performance values of passed
weld specimens tested in.the laboratory.
3.3.8.6 Procedures for Destructive Test Failure
The following procedures shall apply whenever a sample fails a destructive test. CLC
has two options:
1) Reconstruct the seam between any two passed test locations; or
Trace the welding path to an intermediate location (10 feet maximum from the point of th,e failed
test in each direction) and take a small sample coupon for an additional fi,eld test

wrinkle. lf excessive stress points are created at the tail of the wrinkle, the wrinkle should be cut
out and repaired Per Section 3.4.
