Subject: Request for Modification of Statewide Permit No. WQ0035749
Mr. Nathaniel Thornburg,

1617 Mail Service Center
Raleigh, North Carolina 27699-1617
Dear Mr. Thornburg,
The North Carolina Department of Transportation (NCDOT) requests modification to the Statewide
Permit No. WQ0035749 for operations along I-40 in Iredell County. This project is currently under
construction between mileposts 150 and 154 along I-40 and between mileposts 49 and 54 along 1-77,
with portland cement concrete pavement placed within the last 18 months. Due to the location of this
project along Fourth Creek and adjacent tributaries as well as wetlands, land application is not
achievable.
This modification requests to distribute Class A residuals generated from the diamond grinding
operation without discharge of wastes into surface waters. Slurry generated from the above referenced
operations would be placed in temporary earth storage basins for dewatering and future beneficial fill.
Please see the attached documentation along with the modification payment for your review. Thank you
for your assistance and please contact Ilse at 704-380-6050 should you have any further questions.
Sincerely,
Justin Johnson
Resident Engineer

The Lane Construction Corporation
NCDOT Contract # C204163
Introduction
Project Overview
DGS Management Plan
Containment Basin
The Lane Construction Corporation has been contracted by the North Carolina Department of
Transportation (NCDOT) to construct the second phase of the 1-40/1-77 interchange enhancement
project in Iredell County, North Carolina. The second phase of this project is focused on constructing
collector -distributor lanes on 1-40, widening 1-77 from Exit 49B to north of the 1-40 interchange, and
building a partial turbine interchange at the two interstates. The NCDOT contract number is C204163
and the state TIP number is 1-3819B, U-6039.
As part of this interstate reconstruction project, new concrete paved roadway and ramps will be
constructed. Upon completion of this new concrete pavement, the travel lanes and ramps will receive a
diamond ground final surface. Concrete shoulders and bridge decks will not receive grinding.
The concrete paving designated for diamond grinding on this project equate to a surface area of
approximately 243,560-SY which when ground, will generate approximately 1,217,800-Gal of Diamond
Ground Slurry (DGS). This slurry is defined as a Class A residual and the distribution of this material is
regulated. For this reason, NCDENR has issued the NCDOT a statewide Permit (No. WQ0035749) for the
distribution of such Class A Residuals. Specifically, this permit allows for the slurry be land applied and
provides guidelines for doing so.
After a thorough review of this permit and the guidelines, it became apparent that this project
presented challenges that reduced the applicability of the general permit. It was determined
that while Land Application is an option that will be employed on this project, only a portion of the
project's DGS would be able to be managed in this manner.
As a result of the challenges identified, the project was forced to explore options beyond (in addition to)
land applying the DGS. Together, NCDOT and Lane Construction evaluated different alternatives and
finally settled on creating a DGS Management System for this project.
The main premise of the proposed DGS System is to process the slurry by letting the ground concrete
settle out of the solution leaving the water component to be further managed. The water will be
extracted and the ground concrete will be contained.
DGS Management System
DGS is generated as a result the diamond grinding operation. During this operation water used
to cool the blades of the grinding machine mixes with ground concrete to create a slurry. This

slurry is then vacuumed up by the grinding machine. When land applying, the slurry captured
by the grinder's vacuum is typically pumped directly onto the dirt shoulder adjacent to the
roadway. However, for this project the slurry will be vacuumed up by the grinding machine and
deposited into a waiting tanker truck. The slurry that is pumped into the tanker truck will be monitored
for high pH levels. Muriatic Acid will be added to the tanker as required to keep it within allowable limits
for transport (pH<12.5). The tanker will then take the slurry to a containment basin located within the
NCDOT Right of Way of this project. The slurry will be deposited into the basin and it will be allowed to
settle.
As the DGS settles, the ground concrete will fall out and the water to rise. Water will be pumped from
the containment basin into an evaporation basin. Should evaporation rates not keep up, water will be
pumped from the evaporation basin to another tanker truck which will transport the water to areas
where it can be land applied.
The ground concrete component of the slurry will be collected in the containment basin and allowed to
dry. Once dry, the material will be subjected to the paint filter test and upon passing will be mixed with
earthen material from the project and buried in place. The entire area of the DGS Management system
will be brought up to final grade and grassed per the plans and specifications of the project.

trve & rrocess bummary: _
The 1.4011.77 Interchange Enhancement project located in Iredell County INCDOT Contract: C204163], includes a new
concrete paved roadway and ramps with a Diamond Ground final surface. lane Construction is the contractor responsible
for delivering this new Diamond Ground Roadway- While there is a general NCDENR permit in place for land Applying the
blurry generated from the diamond grinding operation (W(M3749 - Distribution of Class A Residuals), it was determines:
not to bean effective solution for this project. This project poses multiple challenges that make general land application
difficult and/or unallowable- (i.e. limited flat/open areas, jurisdictional streams, wetlands-1
With the understanding that this project would need to find a solution other than (in addrtron to) Land Application, Lane
worked closely with NCDOT to explore alternatives. The selected alternative calls for a system to be setup to process and
contain the Class A residuals resulting from the Diamond Grinding Operation. The overall goal is to manage the slurry onsite
with a process that ensures Safety and Compliance.
The proposed process for this project is as follows:
1.40/1.77 Statesville OG5 Management Process:
he Diamond Grinder(s) that work on the roadway require water to keep their blades cool- This water combines with
concrete grindings to form a slurry which is vacuumed up by the grinding machine and held in a tanker truck. This slurry will
be monitored for pH and Muriatic Acid will be added to the tank as required to keep it within tolerable limits for transport.
Once full, the tanker truck will take the slurry to a containment basin that will be located between-YRPCA- and 1.77 at
approximate mile marker 52. (This location is completely within NC00T Bight of Way)
once at the containment basin, the slurry will be deposited into the basin and allowed to settle- In so doing, the ground
c oncrete will fallout and water will rise. The water will be actively managed by onsite personnel staffed by Lane. After being
I rained, these workers will pump water from the containment basin into an adjacent evaporation basin. Pond fountains may
be used to facilitate rapid evaporation -
Due to the amount of water that will be introduced at grinding operation, it is anticipated that evaporation alone will not
Suffice as the sole component of the water management plan, For this reason. Lane has evaluated addrttonal means of water
ranagement- Water from the girding operation introduced to the containment basins will be allowed sufficient time for
tiolyd particulates to settle out and then will be recycled and used again by the diamond grinder. Water will also be land
applied as allowable under the general NCDENR permit W0003749. When acceptable, the water will also be utilized in other
operations on the project such as to achieve optimum moisture content in fill material or for general dust surpression.
Upon completion of the Diamond Grinding operation, all of the ground concrete that has settled out in the containment
basin will be allowed to dry- Lane's water management efforts will continue to help this material dry as quickly as possible.
As the material dries out, Lane forces will carefully mound up the material in the basins so that gravity assists in the
dewatering. Water will slowly flow out of the grindings and will be pumped to an evaporation basin- This process wilt
continue until the material passes the paint filter test. At that time, the ground concrete will be mixed with earthen
material from the project and buried in place overtop of the abandoned liner. Once buried, the area will be brought to final
grade and grassed. The location of this containment basin has been selected for this exact reason. This basin and all the
ground concrete will be completely encapsulated approximate 4' below grade-

DGS Management Plan
Containment Basin
This Diamond Grinding Slurry management system has been designed specifically for the 140/ 1,77 InterchangeProject In
fredell County. This project posed challenges that made the general permit (WQ0037491 ineffective as a standalone means
of managing the slurry, Taking these challenges Into account, IAne Construction and NCUOT developed a plan to manage
the slurry that includes separation and containment of ground concrete and then elimination of water,
f he final design presented above was calculated based upon the need to handle a maximum theoretical loading condition.
To get to this theoretical maximum loading, a number of assumptions were made:
+ First: We assumed that the 259E of the entire project quantity of slurry would be introduced at one time.
(Note Using typical Diamond Gnndmg Production rates, to amass this quantity of Slurry would take 3 weeks
of uninterrupted production.I
+ Second; It was assumed that during this moment of maximum loading, zero water is managed. This
means that no amount of water reduction has or is occurring.
(Zero evaporation. No Reuse on site, No land Application, Etc.)
• Thlyd: We assumed that this 2S% loading is the final quarter of the project's quantity. This means that
75%of the project quantity had already been processed through this slurry management system. With
that assumption, the capacity of the containment basin was reduced by the amount of ground concrete
that would have previously settled out into it,
• Fourth: We assumed that the 25 year design storm has occurred during this moment of matiimum loading.
The final design requires; A Containment Basin, an Evaporation Basin and a Weti-Defined Water Management plan.
• Containment Basin: 19449x9' (Bottom Dimensions)

Operations Management
DGS Management Plan
Containment Basin
To ensure successful operation of this DGS Management plan, there are three hold points where testing
and inspections need to occur:
• Tanker Truck pH Monitoring and Control
• Containment Pond Monitoring and pH Control
• Reclamation
Tanker Truck pH Monitoring and Control
During grinding, the residuals will be pumped from the grinding machine into a tanker truck. The pH of
the slurry must be below 12.5 in order to drive the tanker truck on public roads, so the water used in the
grinding operation will be pre-treated with muriatic acid. Prior to leaving the grinding operation, Lane
will check a sample of the slurry to ensure the pH is at an acceptable level. In the event it is not, muriatic
acid will be added to lower the pH level. The form to be used for monitoring pH is included in Appendix
5.
pH sampling will be performed by Lane personnel, under the direction of Allison Summers. All
employees will be trained in the sampling method, EPA test method 9040C, and in the use of the pH
meter prior to beginning sampling. pH measuring devices will be calibrated each day using buffer
solutions 7.0 and 14.0, or according to manufacturer's recommendations.
Containment Pond Monitoring and pH Control
The containment basin as well as the evaporation basin(s) will be visually inspected daily during grinding
operations, or weekly when no there is no grinding occurring. Maintenance will be performed as needed
to keep the system functioning properly. The inspection form found in Appendix 5 will be completed
during each inspection. If maintenance is required, Lane will perform within 24 hours for general
housekeeping, or immediately for critical issues.
Lane will monitor and record the pH of the Evaporation Pond(s) daily when transport operations are
occurring (Land Application, or other uses). These pH observations will be recorded in the form found in
Appendix 5. In the event the pH of the clean water is above 12.5, muriatic acid will be added until the
level is dropped. This will ensure that any water that leaves the DGS Management System is at an
acceptable level before traveling on public roads.
Erosion and sediment control BMPs will be installed and maintained as needed to prevent sediment
runoff from the disposal site.
Reclamation
The DGS Management System is located within NCDOT right-of-way. Once grinding operations are
complete, the slurry remaining in the pond will be allowed to separate completely and any remaining
water will be moved to an evaporation basin. The paint filter test will be used to confirm the cake has no
remaining free liquids before making the determination to close out the system. Additionally, the
Toxicity Characteristic Leaching Procedure test (TCLP) will be performed prior to close out of the system.

HYDRODEMOLITION OPERATION SLURRY
DIAMOND GRINDING SLURRY
Operational Functions
Hydrodemolition Operation Slurry Description and Overview
The hydrodemolition operation slurry (HOS) is generated by the hydrodemolition of concrete on bridge
decks during the deck restoration process. The hydrodemolition operation will typically generate a range
of volumes per bridge with percent solids of the unfiltered water ranging from 0.5 to 10 percent. The
hydrodemolition operation will typically generate a range of approximately 10,000 to 50,000 gallons of
HOS per bridge. The hydrodemolition process shall be managed, monitored, collected, and properly
disposed of as a portion of the bridge deck restoration process. Many variables will determine the
quantity, such as hydrodemolition contractor process, size of bridge deck, total depth of concrete to be
removed, etc. The generated water and solids (slurry) is stable and contains a high calcium value for
application as a lime amendment.
Diamond Grinding Slurry Description and Overview
The diamond grinding slurry (DGS) is generated by diamond grinding of concrete pavement which
generates a slurry material consisting of water and pulverized concrete. This material is collected in
trucks through a vacuum system concurrent with the grinding process. The generated slurry is stable
12

The Lane Construction Corporation DGS Management Plan
NCDOT Contract # C204163 Containment Basin
and also contains a high calcium value for application as a lime amendment. The diamond grinding
process shall be managed, monitored, collected, and properly disposed of. The diamond grinding of
concrete will generate a wide range of slurry volume per project. Many variables will determine the
quantity, such as contractor performing the diamond grinding, length of roadway, etc.
The HOS and DGS shall be collected, hauled, and discharged in accordance with local, state, and federal
regulations. The HOS and DGS will not be allowed to enter storm sewers, bridge drainage downspouts or
bridge approach downspouts, ditches, surface waters, floodplains or wetlands. The HOS and DGS will be
monitored to confirm its compliance with conditions in Non -Discharge Permit No. WQ0035749 to
include:
• Calcium Carbonate Equivalence (CCE)
• Percent Total Solids
• pH
When land application of HOS is not a feasible option, the primary method of disposal will be to
transport the HOS to a local publicly owned treatment works (POTW) or a licensed treatment or disposal
facility. When land application of DGS is not a feasible option, other methods of disposal will be
determined such as transport of the liquid portion to a local publicly owned treatment works (POTW) or
a licensed treatment or disposal facility and disposal of the solid portion in an approved solid waste
disposal facility.
Maintenance Schedules
Maintenance will be the responsibility of the Contractor performing the hydrodemolition or diamond
grinding operations. In addition, subcontractors must have a current Land Application of Residuals
"Operator in Responsible Charge" (ORC) as certified by the North Carolina Water Pollution Control
System Operators Certification Commission (WPCSOCC).
III. Safety Measures
Safety plans and training will be the responsibility of the Contractor performing the hydrodemolition or
diamond grinding operations. All subcontractors will be required to comply with safety plans and
training as applicable to the Contractor's performing the hydrodemolition or diamond grinding
operations. NCDOT recognizes that the safety of employees and contractors is paramount to the
maintenance and construction of the state transportation system. Therefore, NCDOT recognizes no
boundaries in the development and implementation of a world class safety and health program that will
protect their employees, contractors and the traveling public. The NCDOT Safety Philosophy is as
follows:
• All accidents and injuries can be prevented.
• Management/supervisors are responsible, and will be held accountable, for preventing injuries

THE FOLLOWING ACTIONS MUST BE TAKEN IN THE EVENT OF A SPILL:
1. Halt the source of the spill: Ruptured line or valve, or damaged tank unit.
2. Contain spill: Use straw bales to form a barrier. Straw or hay bales can be obtained from
several sources for this purpose. Soil near the site can also be used to form a barrier for
containment.
3. Clean up: Use land application equipment to recover as much of the Hydrodemolition Operation
Slurry (HOS) or Diamond Grinding Slurry (DGS) as possible. After the application equipment has
recovered as much HOS as possible, it will be land applied as per the management plan. A
temporary sump pit may be dug in the containment area to enhance recovery.

6. Reporting: Within 24 hours of a spill the responsible party for land application shall present a
written report detailing the cause of the spill and all action taken in response to the spill.
SPILL PREVENTION PLAN
The spill prevention plan requires that all equipment used to transport HOS or DGS be subject to
periodic safety inspections. Tires, brakes, lights, and turn signals will be inspected for proper working
order. Each truck will be equipped with safety flares and appropriate signs to be used in the event of a
breakdown. Any deficiencies observed during the safety inspections will result in the vehicle being
removed from service and the responsible party for land application will be notified so that these
deficiencies can be corrected and documented.
Routes leading from the storage point to the land application sites will be inspected for road hazards.
The road hazards will be documented and the drivers will be informed of the hazards. Alternate routes
will be investigated and routes which minimize road hazards will be selected. Hazardous situations
resulting from rush-hour traffic will be avoided during hauling.
Drivers and management personnel associated with the hauling of HOS or DGS will be instructed in the
spill prevention plan and will be required to attend training sessions. Drivers will be trained in defensive
driving techniques in order to minimize road hazards. A driver who observes a road hazard will be
required to report the hazard to the field superintendent who, in turn, will warn other drivers. As part of
the spill prevention plan, drivers will be required to inspect the safety equipment of their vehicles on a
daily basis. Any deficiency in safety equipment will be noted for corrective action. Drivers will be trained
in the procedures to be taken in the event of a spill that occurs during the hauling of HOS or DGS. These
procedures are discussed in the spill control, containment, and cleanup plan.
SPILL CONTROL, CONTAINMENT, AND CLEANUP PLAN
Spills that occur during loading or unloading HOS or DGS will occur at the generation point and the land
application sites, respectively. These spills will not involve an environmental hazard or an over the road
hazard and, therefore, will be handled using the equipment that will be available at either site. Spills
that occur over -the -road will be subject to the contingencies contained in the spill control, containment,
and cleanup plan. The equipment used in the spill control, containment, and cleanup consists of the
following:

NCDOT Contract # C204163 Containment Basin
1. Vacuum pump, pump truck or tanker truck. A vacuum truck, vacuum pump or tanker truck will
be used to assist with clean up of HOS or DGS spills.
2. Outside equipment if required
The following personnel will be involved in the spill control, containment, and cleanup.
1. The responsible party for land application will respond to the spill site and make an assessment
of the spill and determine the containment procedures to be initiated and the equipment to be
used to clean up the spill.
2. The responsible party for land application will be responsible for the direction of the cleanup
team.
In the event of a spill, the driver of the truck or application vehicle, if he has not sustained a debilitating
injury, will call the responsible party for land application and report the spill. The responsible party for
land application will notify the appropriate authorities and will also notify the appropriate DWQ
Regional Office. The driver will set up safety flares and signs to warn motorists of the hazard. The
responsible party for land application will mobilize the necessary equipment and personnel to the site,
and will initiate the containment procedures. When the cleanup team arrives at the site, the site will be
cleaned up according to the contingency plan. HOS or DGS cleaned up from the site will be transported
to the land application sites where it will be applied in accordance with the permit. In the event that the
driver is incapacitated due to personal injury, the responsible party for land application will mobilize the
cleanup team as soon as the authorities notification of an incident.

POND LINER INSTALLATION TIPS
Liner Delivery
• Your liner material will be delivered to the project location either in a roll or pallet. If
the liner is pre -fabricated and made in multiple panels, each panel will normally be
in one pallet. The liner material is wrapped in geotextile fabric to protect it during
transport. Inspect the material as much as possible and do not accept if major
damage is evident.
• Handle the material with care during deployment and avoid actions that can
potentially damage it.
• We recommend the use of a skid steer that is capable of handling the material
weight and can help in unloading and moving the liner to avoid damage. This can
also aide in unrolling the liner panel.
• Store the liner in a dry area. The liner should be stored and covered at all times if
possible.
DO NOT ATTEMPT LINER INSTALLATION DURING WINDY OR RAINY DAYS!!!
Liner Installation
• During installation, inspect the liner and immediately report any damage. If the
material has been damaged during transit or in the manufacturing, it will be
replaced or repaired as soon as possible at the suppliers expense
• Before unrolling the liner, the pond shall be ready, dry and free of rocks or any
sharp objects that can potentially puncture the liner. The pond perimeter is trenched
about 2 feet deep and 1 foot wide.
• Each liner panel is accordion folded. Place the liner at the edge of the pond, unfold
sideways then unfold towards the pond. You may secure the edge with sandbags.
Leave the liner loose fitting and do not pull tight. Once unrolled, secure the edges
by backfilling the trench.
• When filling the pond, periodically monitor and ensure all areas are secure and the
water is not pulling the trench. Do no fill the lined pond without periodic monitoring.

3 PH100/PH110-en-GB_v3.1 3/15

Overview
pH Overview
pH is a unit of measure (ranging from 0 to 14pH) indicating the degree of acidity or alkalinity of a
solution. pH tests are the most commonly performed measurements in water analysis and reports
the negative log of the hydrogen ion activity of a solution which is an indicator of acidity or alkalinity.
Solutions with a pH less than 7 are considered acidic, solutions with a pH higher than 7 are known
as bases, and solutions with a pH of exactly 7 are neutral.
The pH scale is logarithmic so, for example, if sample A is 1 pH less than Sample B, this means that
Sample A is 10 times more acidic then Sample B. A difference of 1 pH represents a ten -fold
difference in acidity.
Getting Started
• For new meters, remove the battery cap and then remove the battery insulating strip.
• Remove the cap from the bottom of the ExStikTM to expose the electrode glass surface and
reference junction
• Before first use or after extended storage, soak the electrode (with its cap removed) in a pH 4
solution for about 10 minutes
• White KCL crystals may be present in the cap. These crystals will dissolve in the soak or they can
be simply rinsed with tap water
• Always calibrate close to the expected measurement value
• A sponge is located in the electrode protective cap. Keep this sponge soaked with a pH 4 solution
to preserve Electrode life during storage
Replacing Electrodes
The ExStikTM is shipped with an electrode attached. Electrode life is limited and is dependent on
(among other factors) frequency of use and care. If the electrode needs to be replaced, follow these
steps for removing and connecting electrodes. Note that the PH110 has a refillable electrode.
1. To remove an electrode, unscrew and completely remove the electrode retaining collar.
2. Gently rock the electrode from side to side, pulling it away from the meter, until it disconnects.
3. To attach an electrode, carefully plug the electrode into the meter socket (note that the
electrode connector is keyed, ensuring proper connection).
4. Secure the electrode in place by tightly turning the collar in place. (a rubber gasket seals the
electrode with the meter).
Automatic Electrode Recognition
When the ExStikTM is turned on, it recognizes the type of electrode that is connected and displays
the appropriate unit of measure. Attach electrode before turning the ExStikTM on.
Powering the ExStikTM
If the batteries are weak, the `BAT' indicator appears on the LCD. Press the ON/OFF key to turn the
ExStikTM on or off. The auto power off feature shuts the ExStikTM off automatically after 10 minutes
of inactivity to preserve battery life.
4 PH100/PH110-en-GB_v3.1 3/15

Operation
Overview
When the electrode is placed in a solution, the main display and bargraph indicate the pH reading
while the lower display reads temperature (readings flash until they have stabilized). The bargraph
is `center zero', i.e. at pH 7 there is no display. As the pH rises, the bar moves from the center to the
right. If the pH drops, the bar moves from the center to the left.
pH Calibration (1, 2, or 3 points)
A two point calibration with a buffer of 7 plus 4 or 10 (whichever is nearest to the expected sample
value) is always recommended. A one point calibration (choose the value closest to the expected
sample value) is also valid. For best accuracy, always calibrate at the sample temperature.
1. Place the electrode into a buffer solution (4, 7, or 10) and momentarily press the CAL key. pH
7 should be calibrated first, then 4 and/or 10 pH.
2. The ExStikTM automatically recognizes the solution and calibrates itself to that value. Note: If
the solution is more than 1 pH off from the 4, 7, or 10pH standard, the ExStikTM will assume an
error and abort the calibration. CAL and END will be displayed.
3. During calibration, the pH reading flashes on the main display.
4. When calibration is complete, the ExStikTM automatically displays `END' and returns to normal
operation mode.
5. The appropriate circled indicator (4) T , or V will appear on the LCD when a calibration has
been completed. The calibration data is stored until a new calibration is performed.
6. For a two or three point calibration, repeat steps 1-4.
Note: Always turn the meter off and then on before calibrating to allow sufficient time to complete
the calibrations during one power cycle. If the meter auto powers off during calibration the
calibrations remain valid, but new calibrations will turn the circled indicators off.
Note: The Automatic Temperature Compensation (ATC) circuit is not active during calibration. To
ensure a more accurate calibration, make sure that the calibration buffers are at 250C (770F).
RESET
If the meter will not calibrate or displays a -1, reset the meter and attempt to re -calibrate.
Turn off the meter.
2. Remove the battery cartridge from the top of the meter.
3. Press the On/Off button for 10 seconds to bleed off all charges within the meter.
4. Re-insert the batteries and power on the meter.
5. Attempt to re -calibrate the meter.
Changing the Displayed Temperature Units
Press and hold the CAL button for approx. 3 seconds. The °C or OF icon will change first and the
numerical temperature value will change after the button is released. If the Calibration mode is
accidentally accessed `CAL' appears on the LCD. Simply turn the ExStikTM off and start again.
Data Hold
Momentarily press the MODE button to freeze the current reading. The HOLD display icon will
appear along with the held reading. The held reading will also be stored in memory. Momentarily
press the MODE key to return to normal operation.
PH100/PH110-en-GB v3.1 3/15

15-Storing Readings into Memory
1. Momentarily press the MODE button to store a reading.
The LCD will briefly display the memory location
number and then the value stored (Data Hold will z" P" "
activate). 4-0, 10.04
2. Momentarily press MODE again to return to normal 000 r+oLD
operation. 18.87
3. Repeat step 1 to store the next reading and so on.
4. After 15 readings are stored the ExStikTM will return to memory location 1 and start overwriting
existing data with newly stored data.
Recalling Stored Readings
Note: Check that the HOLD symbol is not displayed. If it is, exit the HOLD function by momentarily
pressing the MODE button.
1. Momentarily press the CAL button and then press the MODE button immediately after CAL is
displayed; the storage location number (1 through 15) will flash. If the CAL mode is
accidentally accessed (display flashing), press the CAL button again to exit.
2. The last reading stored will be displayed first. To advance through the stored readings,
momentarily press the MODE button. The location number is displayed first, followed by the
reading stored in that location.
3. To exit the recall mode, momentarily press the CAL button and the ExStikTM will return to
normal operation.
CAL Reminder Display
When the ExStikTM is turned on in the pH mode for the 15th time without recalibration, the `CAL' icon
appears on the LCD indicating that the ExStikTM may require calibration. Some applications may
require recalibration of the electrode more frequently than others. The CAL display is simply a
reminder and will turn off when the pH electrode is recalibrated.
RENEW Display
A flashing `RENEW' warning indicates that the probe may be nearing the end of its useful life. If
cleaning or recalibration does not cause the RENEW icon to disappear, replace the electrode. The
RENEW display appears when the output of the pH electrode fails a diagnostic test.
Considerations
If the unit appears to be locked (display frozen) it is possible that the Data Hold mode has been
inadvertently accessed by pressing the MODE button. Simply press the MODE button again or
turn the meter off and restart if the display appears frozen.
If the meter does latch up and no button presses revive it, remove the batteries, push the ON
button for 10 seconds and then reinsert the batteries.
Note that if the batteries are removed, any stored readings will be discarded. Also, the user
calibration data for pH will be cleared. New user pH calibration data is required. Factory
calibration data for all models will be retained, however.

Dear Director:
In accordance with North Carolina Department of Environmental Quality (NCDEQ)
permit requirements, this is to notify you that the following positions have signature

by NCDEQ related to the facilities and operations performed within their respective
jurisdiction. This written delegation of signature authority is for our Statewide diamond

North Carolina General Statute 136-18.05(la) requires the North Carolina Department of
Transportation (NCDOT) to adopt "...procedures in all stages of the construction process
to streamline project delivery..." It is normal practice within NCDOT for the Division
Engineer to sign all permits and associated documents for any event that occurs within
their Division. Statewide permits applicable to the Division of Highways are signed by
the Chief Engineer, and Department -wide permits applicable to all of the Department of
Transportation are signed by the Secretary of Transportation. The Division Engineers are
the responsible parties for the specific DGS/HOS projects performed within their
respective Division.
Therefore, I hereby delegate signature authority for associated permit modification
applications, reports, plans, and information requests to individuals who hold the
following position at the time of their signing said documents: Division Engineer or
Acting Division Engineer.
This authorization is applicable until further notice or changes are made in writing
