6. Wastewater treatment alternatives
What wastewaters were considered for this alternatives review: ® VE ® RM ® MD
Are there existing sewer lines with a one mile radius: ® Yes ❑ No
If Yes:
❑ The wastewater treatment plant will accept the wastewater. It is feasible to connect. Explain:
❑ The wastewater treatment plant will accept the wastewater. It is not feasible to connect. Explain:
® The wastewater treatment plant will not accept the wastewater (attach a letter documenting)
® Surface or subsurface disposal is technologically feasible
❑ Surface or subsurface disposal is not technologically feasible
Explain: Surface discharge of treated wastewater is technologically feasible.
❑ Surface or subsurface disposal system is feasible to implement
® Surface or subsurface disposal system is not feasible to implement
Explain: There is no available area within the facility for a potential surface disposal system. The volume of discharge will require a large system installed in a
large area that is not available. In addition, the temporary nature of this facility makes the installation of such system not feasible.
What is the feasibility of employing a subsurface or surface discharge as compared to a direct discharge to
surface waters? Explain: Due to the temporary nature of this facility, direct surface water discharge of treated waste water is significantly more
economically and environmentally feasible.
Discharge to surface waters is the most environmentally sound alternative of all reasonably cost-effective
options of the wastewaters being considered:
0 Yes
❑ No— contact DEMLR's Land Application Unit to determine permitting requirements
If this review included all wastewater discharge types, would excluding some types make of the above non -
discharge options feasible?
❑ Yes
® No

Waste Water Treatment Plan
1 - Background
The Lane Construction Corporation has been awarded the NCDOT contract for the
reconstruction of a portion of Interstate 1-40 in Orange County, NC. This project requires that
approximately 150,000 cubic yards of concrete be produced and placed into the new roadway.
In order to facilitate this construction, a temporary portable concrete batch plant will be erected
within the Right of Way of the project at a parcel of land located at Highway NC 86 (intersection
with 1-40). Please refer to the location maps provided within this application.
The concrete plant that is being proposed in this application will exist solely to provide concrete
for the above -referenced project. The concrete plant will only be active during intervals of
concrete paving. Upon the completion of concrete paving, this plant will be removed and the site
will be repurposed.
2 - Waste Water Generated
There will be three different types of waste water generated at this site which need to be
analyzed.
The first will come from the cleaning of the concrete hauling units. Dump trucks will be utilized to
haul the wet concrete and will need to have their dump bodies rinsed out after each load. This
water will combine with the concrete that is rinsed out of the dump body and will contain all the
elements of the concrete (Sand, Stone & Cement). No other cleaning or repair of these vehicles
will occur at this site.
The second waste water generated will be the wash water produced after cleaning the plant's
mixing drum. The composition of this water will be the same as that produced during the dump
truck rinsing operation. This cleaning of the mixing drum will occur upon of the completion of
each shift and also as necessary throughout the shift.
The third waste water generated will be the water used to wet the raw aggregate stockpiles.
These stockpiles will be watered consistently during concrete production operations. Water that
flows from these stockpiles will contain suspended fine particles that have escaped from the
stockpiles.
3 - Waste Water Control & Treatment
In order to effectively treat the wastewater generated by this setup, it must first be collected and
brought into the appropriate containment areas.
The wastewater basin is intended to collect the wastewater described in Item 2 of this
document. Additionally, there is a stormwater basin intended to capture the stormwater run-off
from a portion of the site. The site will be graded and diversion ditch lines will be established.to
ensure that the wastewater and stormwater will flow as intended.
The Concrete Wash Water will be introduced into a series of basins designed to effectively
settle all suspended particles and also to ensure that the pH of the outflowing water is within the

acceptable range. To do this, three basins will be created. The first basin in the series is the
"Washout Pit" where the dump trucks will.be sprayed and the concrete will be directly mixed into
the system. This is also the location where wash water from the mixing drum will be transported
to. The second basin is designed to be the "Settling Basin" which is a very large retention basin
sized to provide adequate settling time to ensure that the fine particles have settled out prior to
outflowing into the final basin. The third basin is the "pH Reduction Basin" which is where a
Fortrans System will be installed to monitor and regulate the pH of the wash water.
As an additional measure and to increase the safety factor of the system, the water coming out
of the stormwater basin will be diverted to the pH control basin to ensure this source is also
within acceptable levels.
Predicted Maximums and System Performance
The concrete wash water treatment system has been designed for a concrete plant running at a
regular maximum production of 2,000 CY per day. This volume will result in a wash water flow
of approximately 2,420 CF/Day. In actuality, this production rate will only be achieved a limited
number of times on this project. However, it is important to calculate the waste water treatment
system based upon the project maximums and not the averages.
Upon release from the treatment system, the TSS and SS levels in the outflowing water will be
less than the established limits (30 mg/I and 5 ml/I respectively), and the pH will be within the
acceptable 6-9 range.
Maintenance of System
Basins and BMPs will be inspected regularly, and documentation made in accordance with the
facility SWPPP. Any damage to the devices will be repaired immediately and any sediment that
has been built up will be removed routinely. This system has been designed to allow for easy
access and maintenance which will help to ensure that it functions properly.
During intervals where the concrete plant is active the wash water basins will be inspected on a
daily basis. It is anticipated that at a minimum the "Washout Pit" will require routine cleaning
during these intervals. The aggregates that will accumulate in this basin will begin to impact the
function of the system if they are allowed to build up. It is the responsibility of Lane to ensure
that this buildup of materials is removed on a timely basis.
Summary
The purpose of this treatment system is to monitor and control pH and settle TSS resulting from
concrete washing operations before it leaves the site. This treatment system has been used
successfully at previous sites for concrete batch plants, most recently this exact treatment
methodology was used for similar NCDOT projects in Guilford County (Contract Nos. C203197,
C 203399, and C203792). The rules and guidelines set forth by general permit NCG 140000 will
be strictly adhered to and BMP's will be employed and maintained. Any questions regarding the
operation of this facility can be directed to the facility contact noted in the application.

DATE: 12/7/2022
Lane has proposed to construct and operate a temporary portable concrete
batch plant to facilitate the construction of the above referenced project. Given the provided
technical information regarding concrete plant operations, specific to this plant and project,
the volume of "Wash Water" needs to be calculated and a treatment system needs to be
There are two sources of "Wash Water." The first being the water used to wash out the beds
of the wet batch hauling concrete dump trucks after each load. This operation is completed
by spraying the truck bed with a fire hose. The wash water then flows from the truck bed into
the washout pit. Once the washout pit fills, washwater will be skimmed from the surface with a
pump and reused to spray out truck beds. (This is done as a water conservation effort.)
The second source of wash water is the water that is used to clean the plant's mixing drum upon
completion of each shift and as needed throughout the shift. This operation is completed by
spraying the drum, letting it mix then dumping the wash water into a loader bucket for
transport to the washout pit.

ana uetan of i reatment
The Wash Water will contain waste concrete and as such there will be Suspended Solids.
Concrete is a mixture of Course Aggregate (Stone), Fine Aggregate (Sand), Cement
and Water. The aggregates will settle out of the wash water almost instantly and be
deposited at the base of the system. However, the cement will require a much greater
settling time due to its average particle size being quite small. It is the cement particle that
this water treatment system is designed for.
As detailed on the plan sheet, this system will employ three basins which will work in series.
The first basin is the "Washout Pit" which is where all the aggregates will settle out of the
wash water, leaving only the cement particles to flow into basin 2 which is the "Settling Basin."
The "Settling Basin" is where the fine particles (Cement) will settle out of suspension. As
designed, this basin is to have a 4:1 Length to Width Ratio in order to maximize the amount
of time required for wash water to flow through the basin.
From the "Settling Basin" the wash water will move into basin 3 which is the "PH Reduction"
basin. Since cement is very alkaline (pH 12-13) it is necessary to monitor and control the wash
water prior to it's release from this system. A "Fortrans" system will be setup at basin 3 which
will ensure that pH levels are acceptable prior to release. (Please seethe manufacturers
specifications, which are included in the Appendix, for details and performance expectations)
It is also noteworthy that each basin will be connected by a "Rock Sediment Dam." These BMP
structures employ wide weir's which allow for a thin layer of surface water to slowly move
between each basin. The main purpose of a sediment dam is to "skim" the surface water
(cleanest water) from the upstream basin and allow it move on to the next basin in the series.
This "skimming" characteristic is essential for the proper operation of this system. It
essentially works to trap the smallest particles (cement) that are suspended in the wash water.
These tiny cement particles range in size with its smallest particle being only 1 Micron in
diameter. The retention time required to completely settle out a 1 Micron particle is
extremely difficult to provide. However, creating a system that traps these minute particles is
much more feasible. This system is designed to trap suspended particles in each basin, the
smallest of which will be trapped and eventually settled out in basin 2, the "Settling Basin."

Realistically most of the suspended cement particles have settled out in the Washout Pit.
Then, an additional amount of suspended cement settled out at the Rock Sediment Dam.
However, for an increased factor of safety the analysis of basin 2 is to be performed with the
assumption that all suspended cement has passed from basin 1 into basin 2.

M CONTROL SYSTEMS CONCRETE REMOVERS
Copyrighted information
The Model 5000 series pH Control systems use a patented Dif-JetTM non -fouling
carbon dioxide gas diffusion and injection process to lower the pH of process
water and or storm water at ready mix concrete plants, and precast concrete
manufacturing operations. These systems also lower Total and Suspended Solids
to low levels.
The programmable logic controller in the system can be set to lower the pH to
almost any end point. The controller is pre-set to maintain a pH of 7.5 in the
detention basin.
The system is installed on a 10'x 10' concrete pad adjacent to the pit, basin or
tank with the cleanest, most settled water. The system circulates the water in the
containment basin with a submersible pump in a closed loop piping system and
continually monitors the pH level. When the pH rises to 8.25, the controller will
actuate a solenoid valve and begin to diffuse and inject carbon gas. Once the
water is at a pH of 7.5, the valve shuts off and the water circulates until the pH
rises to 8.25 again. The range may be adjusted to the owner's preference. For
example, the "on" set point can be set to 7.5 and the "off' set point can be 7.0 for
a lower tighter range.
High pH process water contains a high levels of suspended and dissolved
solids, primarily calcium hydroxide. The carbon dioxide forms carbonic acid
when it is dissolved in water, the reaction between the carbonic acid and
calcium hydroxide forms calcium carbonate which is insoluble in water and
precipitates out of the water. Typically, the 'Total Suspended Solids" reading
will be from 14 to 17 after pH adjustment. The EPA permits discharge of treated
process water when the pH is 9.00 or lower and the TSS (Total Suspended
Solids) is under 30.
As part of a water recycling program, the treated water may be used to batch
concrete, for dust control, truck washing and irrigation of lightweight aggregate
or release from the property according to the storm water permit for the plant.
The treated water may also be returned to the municipal waste water system.
pH adjusted water does not scale up windshields or paint. It will not scale up
pumps, valves or fittings so maintenance costs are lower compared to using
high pH process water to batch concrete.
Also, having a basin or pit of pH adjusted water will generally help in managing
stormwater as the "buffered water" will neutralize most of the stormwater that
enters the basin. These systems are useful for treating and maintaining
stormwater containment to avoid discharging high pH water.

Carbon Dioxide costs about .29 lb delivered. Typical CO2 cost will be around
$6.00 per day per 10,000 gallons of high pH water. This figure may vary
depending on the actual pH and total alkalinity of the process water,
The systems include everything needed to operate except the CO2 supply and
tank. Fortrans supplies a Victor SR-31-320 high flow CO2 regulator and nylon
supply hose. The final 115V- 20 A electrical connection is by others.
A small amount of schedule 80 PVC piping and fittings to construct the return
outlet per our supplied drawing will also be required.
Fortrans does not recommend "batch treating" of process water. Once the
system is installed; run continually during plant operating hours. The system will
not use more CO2 than if batch treating and scaling in piping and lines will be
greatly reduced.
The Model 50005, 50008 and 5000SK all have the capacity to treat up to
75,000 GPD. The systems are supplied with operation manuals that contain
detailed operating and maintenance instructions, installation instructions and
drawings that show how to set up the pump and pump boom and how to install
the discharge piping
Comoetitive Information
The Model 5000S pH Control Systems cost approximately 60 to 70% Tess to
purchase and operate than acid based neutralization systems. The cost savings
is based on using less pounds of CO2 than sulfuric acid or hydrochloric acid.
Sulfuric Acid based systems or sodium bisulfate systems will increase Total
Suspended Solids. A separate filter will be required to meet EPA standards for
discharge.
Fortrans' systems do not use corrosives, all of the components last longer. No.
hazardous chemical permits are required.
All systems are ouaranleed to perform to our customer's satisfaction

PURPOSE
G.C. Environmental, Inc., was contracted to provide an engineers review and certification that the
Model 5000-S pH Monitor and Control System manufactured by Coastal Carolina Supply in
Morehead City, NC, could cffectivelyprovide on a continuous basis, an average pl-1 range of6-9 units
on the supernate layer of a stormwater/rinse water sedimentation basin typically found at Redi-mix
concrete facilities.
SCOPE OF WORK
During theweck of August 11, 2003, G.C. Environmental, Inc., witnessed the operation oftlte Model
5000-5 self-containcdpH Monitoringand Control System ata Rcdi-mix plant located in Durham, NC.
During the two (2) day test program, measurements were made within the facilities :normwatcr/rinse
water sedimentation basin for pl-1, temperature and depth (both supernateand sludge). DuringthefirsL
day of testing, the basin was (found to be heavily loaded with solids and adjustments were made to the
solids blanket to complete testing the following day.
TEST M ETHODOLOGY
A primary sedimentation basin located at a Red! -mix concrete plant located in Durham, NC was
treated utilizing the Model 5000-5 pH Monitor and Control System, During the test program, the
basin .vas, on a semi -continuous basis, being fed rinse water from the exterior cleaning or cement
trucks. Measurements for pH, temperature, supernate and sludge blankets were made within the
sedimentation basin. Initial pH measurements showed pl-I levels of at least 12.0 units. The
sedimentation basin was rectangular in shape with concrete walls and bottom. The basin ranged in
depth oft ° at the inlet to approximately Y atthedeepest point. Sludge measurements within the basin
showed that at least 213 of the basins depth was comprised of sludge and the remainder supernate.
TheModc15000-S pl-I Monitor and Control System Was setup at the rectungularsedimentation basin
with the intake and discharge hoses situated at opposite ends of the basin. Both the intake and
discharge lines were set at depths within the supernate layer orthe basin. A clockwise flow pattern
was established once the unit began operation and pl-I and temperature measurements were made at
several locations throughout the supernate layer of the sedimentation basin. Approximately eighteen
(18) pl-I and temperature measurements were collected with it mean pH value of SSG and mean
temperature values or30 94 °C. The pH system was left to run essentially on a continuoushacis over
a four (4) hour period. An estimated volume existing within the sedimentation basin was 25, 000
gallons with a little over 8000 gallons consisting of relatively clear Supernate. The amount of 25%

Sulfuric acid (H,SO,) used to treat the sedimentation basins supernate was approximately 18-20
gallons.
MODEL 5000-S Pit MONITOR AND CONTROL SYSTEM
The model 5000-S pH Monitor and Control System is comprised ofa Hayward Power plow 11 (3/4
hp, 56 GPM) centrifugal pump which delivers raw water to a completely contained pH sensor
connected to a pF1 meter equipped with control relays which operate two (2) stenner (60 GPD) acid
injection pumps. The acid 25% H,SO4 is injected into the pump discharge line which empties into the
sedimentation burin. Sulfuric acid is delivered to the system by 15 gallon carbuoys located outside of
the fiberglass weatherproofenclosurc which houses all ofthe aforementioned equipment. On top of
the enclosed is an alarm lightwhich is tied into the pH meterwhich is activated when pH levels exceed
8.5 pH units or are below 6.0 units.
CONCLUSION
1. The Model 5000-S pH Monitor and Control System is an effective system for the pH balancing of
sedimentation basins which are used to collect stormwater runolfand rinse water, commonly found
at Rcd-mix concrete plants.
2. During the test program an average pH of 8.54 units was measured in the subject sedimentation
basin with a range of 7.95 to 9.34 measured.
3. Sludge levels existing within the rectangular sedimentation ranged from 6.0 inches to 2.0 feet. PH'
values after pH stabilization at the sludgetsupemate interface were approximately 12,0 units
4. For this test program, approximately 180 mgA ofsulfates were added to the sedimentation basin as
a result of pH adjustment with 25% sulfuric acid.
5. 'rho 5000-S pH Monitor and Control System is fully automated and provides a pH adjusted waste
water which could effectively he reused within the Redi-mix concrete industry.

FORTRANS pH CONTROL SYSTEMS
FORTRANS pH CONTROL SYSTEMS are
completely automatic. They continually monitor/test
the pH of the influent water and compares • it to the
PH setting of the control unit. If a change In pH is
detected, the controller activates the solenoid valve
for the CO2. The pH adjustment chemical is then fed
to the return side of the circulation pump until the
pH is again at the proper level set at the controller.
The unit will continuously circulate the water until a
change in pH is detected and the treatment cycle
begins once again. The unit also features a digital
pH meter connected to a probe In the sample cell
to ensure unit Is functioning properly and that the
correct pH level Is maintained.
The pH CONTROL SYSTEMS are designed to
treat and maintain a specked pH level in a body of
water usually 100.000 gallons or less to allow the
permitted discharge of treated water to the
environment. Permits must be obtained from the
local governing agency to allow any discharge to the
environment. Treated water may be used for wetting
of rock and/or dust control to aid compliance with
stormwater run off regulations. Treated water may
also be used in water recycling systems.
These systems offers precise monitoring and
control of the pH In settling basins, lagoons and
other outfall containment devices.
-The pH CONTROL SYSTEMS will treat up to
57 gallons per minute - Max 20' head pressure.
Unique water circulation design eliminates the need
for separate neutrallzatlon tank.
•1.5" quick connect fittings on inlet and return
for easy hook-up. The standard unit Is equipped with
2-30'sections of 1.5" flexible hose with quick connect
0ttings. Inlet and outlet (filings at the basin or lagoon
are per our specifications-
-Unit is shipped completely assembled. The
chemical controller Is preprogrammed to maintain a
pH of 7.5. Just attach hoses and PVC fillings.
.1 year warranty on all component parts
and housing.
