Dear Mr. Thornburg:
The North Carolina Department of Transportation (NCDOT) requests modification to the Statewide Permit No.
WQ0035749 for operations along 1-85 in Rowan County. This project is currently under construction between
mileposts 63 and 68 with portland cement concrete pavement placed with in the last 14 months. Due to the
location of this project along Cold Water Creek and adjacent wetlands, land application is not achievable.
This modification requests to distribute Class A residuals generated from diamond grinding and hydro demolition
operations 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 me at 704-630-3220 should you have any further questions.

The Lane Construction Corporation DGS Management Plan
NCDOT Contract# C203702; TIP# 1-3802B
I. Introduction
The Lane Construction Corporation has been contracted by the North Carolina Department of
Transportation to make improvements to 1-85 in China Grove, North Carolina, from
approximately mile -marker 63 to mile -marker 68 under Contract Number C203702, TIP Number
1-3802B. Part of this contract requires the diamond grinding of approximately 330,000 SY of
Portland Cement Concrete Pavement, which will take place between August and October of
2019. As a result, we estimate the generation of approximately 8,200 CY of liquid slurry, of
which approximately 1,700 CY (est. 3,400 TN) will be dry solids (cake). These estimates are
based on values from previous projects, see Figure 1. This waste is defined as Class A
residuals, and the distribution of this material is regulated by NCDENR, under Permit No.
WQ0035749 held by NCDOT. Lane has prepared this Management Plan to facilitate the
transport and disposal of this waste.

II. DGS Management Plan Summary
During grinding, slurry will be vacuumed up, and deposited into a tanker truck. Once a tanker
truck is full, it will leave the grinding operation and go directly to the residuals processing facility.
There, the truck will completely discharge all residuals into the treatment system, and return to
the grinding operation. Waste will be processed by the system. See Appendix 1 for a diagram of
this process.
Prior to grinding, the water to be used to cool the diamond blades will be pre-treated with
muriatic acid. This will drop the pH of the resulting wet slurry recovered below 12.5. The pH of
the slurry will be checked on each truck, prior to departure from the grinding location.
Upon completion of grinding operations, any remaining slurry within the basins will be allowed to
dewater, and the remaining dry cake will then be incorporated as beneficial fill in the restoration
of the basin to natural ground level.
III. Treatment and Disposal
The treatment system for this operation is made up of three containment ponds, which will be
developed out of existing erosion control settling ponds. The first two ponds are in a tiered -
configuration, and provide two functions; first, to settle out the solids from the slurry, and
second, to provide final containment for the solids. The last pond in this system will be used as
a holding -area for the clean water separated from the slurry. This pond will provide additional
surface area for evaporation to take place, as well as a reservoir for clean water to be collected
for mechanical diffusion, and for reuse in grinding operations, as seen in Appendix 1. Detailed
information about the treatment system can be found in Appendix 2.

The Lane Construction Corporation DGS Management Plan
NCDOT Contract# C203702; TIP# 1-3802B
All ponds will be lined with an impermeable plastic film. Technical information about the liner
can be found in Appendix 3. Seams will be double taped with rubber tape in the following way:
i. Overlap adjacent plastic sheets 18 inches

This system is located on the east side of 1-85, off of newly constructed Old Beatty Ford Road in
China Grove, on NCDOT right-of-way. Because this roadway was only recently constructed,
there is no physical address, however the approximate coordinates are, latitude 30°32'3.72" N,
longitude 80°34'22.86" W.
IV. Operations Management
For adequate operation of this treatment plan, there are three primary areas to manage:
1. Tanker Truck pH Monitoring and Control
2. Containment Pond Monitoring and pH Control
3. Reclamation
Page 4 of 6

The Lane Construction Corporation DGS Management Plan
NCDOT Contract# C203702; TIP# 1-3802B
1. 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 as Appendix 4. Each tanker truck will be checked
before entering public roads.
pH measuring devices will be calibrated each day using buffer solutions 7.0 and
14.0, or according to manufacturer's recommendations.
Personnel taking samples will be trained and certified in the correct use of the pH
measuring device, and perform testing per EPA Test Method 9040C.
2. Containment Pond Monitoring and pH Control
Containment ponds will be visually inspected daily during grinding operations, or
weekly when no there is no grinding occurring, and maintained as needed to
remain properly functioning. 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 daily 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
recycled water used on site 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.
3. Reclamation
The treatment 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 either evaporated off
naturally, or mechanically diffused via water truck. 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. The Toxicity Characteristic Leaching
Procedure test (TCLP) will also be performed prior to close out of the system.
Close out of the basin will take place as follows:
i. Move all cake from Basin 1 to Basin 2
ii. Remove liner from Basin 1
iii. Perform soil testing on soil in Basin 1
iv. If necessary, amend soil in Basin 1
V. Move all cake from Basin 2 to Basin 1

basins to natural ground, and establishing the slopes for the roadway.
V. NCDOT General Operation & Maintenance Plan
This DGS Management Plan has been prepared in accordance with the NCDOT
General O&M Plan, which has been included for reference in Appendix 6. The General
O&M Plan provides an overview of the grinding process, and outlines general practices
to be followed during the operation. The practices outlined in this DGS Management
Plan are specific to this project.
VI. Spill Control Plan
The spill control plan for this operation can be found in Appendix 7. This details the
procedure to follow in the event of a spill including how to contain, who to notify, how to
report, etc.

Basin 1 and 2 are designed to be the containment components of this treatment system. The intent of
these basins is to seperate the solids out of slurry, which takes between 3 and 5 days.The basins are sized
to contain 25% of the total volume of wet slurry, with no dewatering, and have enough capacity to contain
storm water runoff from a 25-year storm. The system will be managed such that, as the solids drop out,
the surface water will be removed, keeping the total residual volume low. Lane will provide personnel full-
time managing the pumps in this system to ensure the volumes are maintained. As the solids seperate,
clean water will be pumped from these basins into Basin 3, the "Evaporation Basin", which is intended to
hold clean water for reuse. All three basins will be lined with impermeable plastic lining to prevent
contamination of soil. Regular inspections will also be made to assess the need for general housekeeping
and maintenance.
Recycled water in Basin 3 will be handled in one of three ways: (1) evaporated naturally, (2) mechanically
diffused via water truck, or (3) reused in the grinding operation. Before hauling recycled water on public
roads, the pH will be checked to verify it is below 12.5. In the event it is not , muriatic acid will be added to
drop the pH to an acceptable level.
This system will be graded such that it will catch only a minimal amount of stormwater. The applicable
area for stormwater is essentially only the sides of the slopes, and the surface of the basins.

OPERATION AND MAINTENANCE PLAN
N.C. Department of Transportation
Permit No. WQ0035749
HYDRODEMOLITION OPERATION SLURRY
DIAMOND GRINDING SLURRY
I. 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 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

Operation and Maintenance Plan NCDOT
Hydrodemolition Operation Slurry and Diamond Grinding Slurry Permit No. WQ0035749
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.
II. 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 and occupational illnesses.
• Occupational safety and health is part of every employee's total job performance.
• Working safely is a condition of employment.
• All workplace hazards can be safeguarded.
• Training employees to work safely is essential and is the responsibility of
management/supervision.
• Prevention of personal injuries and accidents is good business.

Appendix 7 - Spill Control Plan
HYDRODEMOLITION OPERATION SL URR Y
DIAMOND GRINDING SL URR Y
SPILL CONTROL PLAN
FOR PERMIT WQ0035749
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.
4. Notification: As soon as possible, but in no case more than 24 hours or on the next
working day following the occurrence, after a spill occurs notify:
• NC DOT: Resident Engineer and Division Environmental Officer
• NC Department of Envirommental Quality
Division of Water Quality Regional Office
❖ Asheville Regional Office [phone]
❖ Fayetteville Regional Office [phone]
❖ Mooresville Regional Office [phone]
❖ Raleigh Regional Office [phone]
Washington Regional Office [phone]
❖ Wilmington Regional Office [phone]
❖ Winston-Salem Regional Office [phone]
❖ Outside of normal business hours, call the emergency hot line: 1-800-858-0368
• Fire Department if assistance is required for wash down
5. Management of clean up efforts: The responsible parry for land application shall take
immediate charge of the clean up activities. Additional labor will be requested as
needed.
6. Reporting: Within 24 hours of a spill the responsible parry 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:
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.
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 parry 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 parry 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.
