(1) If Yes, contact DEMLR's Aquifer Protection Section's Land Application Unit
(2) If No, is this option technologically feasible (possible)? Why or why not?* Yes, it is possible
to reuse treated waste water for equipment cleanup.
(3) If No, is it feasible to build a CLRS on your site? Why or why not?* No. The water storage
requirements for rain events, plus the volume of waste water generated during peak
_production would require the installation of a very large CLRS that will operate for one
a short period of time. This system would also require the installation of pressurizing
equipment to be functional which is not economically or environmental! feasible.

PROJECT:
1-3802B
DESCRIPTION:
1-85 Widening and Improvements
SUBJECT / TASK:
Calculate "Wash Water" Volume from Concrete Plant Operations & Design Treatment System
CALCULATED BY:
CMA
DATE:
12/7/2016
Objective:
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 designed.
Wash Water:
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.

Setup ana uetaii of i reatment bvstem
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 this 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. Being that the settling time in this
basin is so imperative, baffles are also to be installed to ensure that "Short Circuiting" is not
possible. (Four Baffles are to be installed dividing this basin into Five equal size chambers.)
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 "Fortran" system will be setup at basin 3 which
will ensure that pH levels are acceptable prior to release. (Please see the manufacturers
specifications, which are included in the Appendix, for details and performance expectations)
Upon release from the "pH Reduction" basin wash water will then disperse and flow across
approximately 100' of undisturbed grass field prior to reaching its receiving water, which is an
unnamed tributary of the Yadkin River.
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."

Therefore:
The average Cement Particle will settle out of the wash water in the "Washout Pit."
This will leave only the smallest of particles to analyze in the "Settling Basin."
Page 5 of 8

Analyze Settlement of Particles too Fine to Completely Settle Out
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.

Total Settling Time Provided by Basin 2:
Therefore:
11.08 Days * Calculated Previously
1.5 Micron sized particles are the largest that might not completely settle out.
These particles will need to be "Trapped" to prevent them from moving on.
Settling Required to Effectively "Trap" Suspended Particles
Depth of Basin (At outlet Weir): 3 Ft Length of Basin: 340 Ft
Assuming that flow is spread equally across width of basin (Baffles should ensure this) settling
time of suspended particles will have a linear correlation to Basin Length. For an added
factor of safety assume that all suspended particles need to have settled at least one third of the
total weir depth to be considered effectively "trapped."
Settled depth of Smallest "Trapped" Particle (1 Micron) at Weir: 1 Ft
Retention time required to settle a 1 Micron particle to this depth: 11.38 Days

Notes:
This System is Designed to effectively treat the wash water for a concrete plant
running at Daily Production Rate of 4,000 CY. The outflowing wash water from this
plant setup will be in conformance with the NCDENR allowable limits for pH, TSS & SS.
This is a temporary concrete plant setup which exists only to service an NCDOT
project. As such, the production rate of 4000 CY/Day will only be achieved a limited
number of times during its lifespan (Less than 2 yrs.). It should be expected that this
system of containment basins will be dry for approximately 70% of their existence.
During these dry periods there will be no outflowing wash water at all.
(Zero TSS, SS, and no pH to Consider)
The Fortran System will be installed to treat the outflowing wash water which will
develop during high production intervals. Since these high production intervals are
anticipated to be infrequent the "pH reduction" basin will be dry for the majority of its
existence. During times where the "pH Reduction" basin is dry, the installed Fortran
System will be inactive.
The wash out basin shall be inspected daily during high production intervals and be
cleaned as necessary. It is important that aggregates and settled fines do not impair
the effectiveness of the Rock Sediment Dam leading into the Settling Basin.
Accumulated aggregates and settled fines shall be properly removed and disposed of
by the Flatiron -Lane.
The settling basin shall be inspected regularly and maintained as necessary. It is
important to ensure that the installed baffles are functioning properly (spreading flow
across width of basin). Replace/Repair any deficient baffles as necessary. Settled
fines are to be removed by Flatiron -Lane as frequently as possible (When dry) to reduce
the risk of their re -introduction into system. At a minimum, settled fines are to be
removed when any basin chamber is 20% full.

Stormwater Pollution Prevention Plan
For
Lane Construction's Temporary Concrete Batch Plant
Background
The Lane Construction Corporation been contracted to build 6 miles of interstate concrete pavement for
the NCDOT contract TIP 1-3802 B, the 1-85 Widening and Improvements on the 1-85 corridor in Rowan
County. 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 constructed on a private parcel of land that has been leased by Lane. The physical
address of this location is 1500 N US HWY 29, China Grove, NC 28023.
The concrete plant that is being proposed in this application will exist solely to provide concrete for the
1-85 project. As scheduled, this entire project will be completed by December 2018 and the concrete
plant will be removed in advance of this date. It is anticipated that this plant will only be in existence
for approximately 18 months, and during that time it 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
restored.
Waste Water Generated
There will be four 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 wastewater 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.
The final waste water generated at this site is storm water runoff. Currently the site is a wooded field,
which will need to be stabilized prior to the concrete plant being setup. Once the area is stabilized the
amount of runoff becomes much greater and has the potential to create erosion.
It should be noted that all four types of waste waters described here will need to be treated for
particulate matter, however only the waste water from the cleaning of haul units and the mixing drum
will need additional treatment for pH,

LANE
Waste Water Control & Treatment
In order to effectively treat the waste water generated by this setup it must first be collected and
brought into the appropriate containment areas. As designed the treatment plan for this site will
separate storm water runoff from concrete wash water. The site will be graded and diversion ditch
lines will be established to ensure that storm water will flow into SW Bain #1 and #2 (southernmost and
easternmost basins respectively) while the concrete wash water will be introduced into another,
separate, series of basins. This separation will allow for a higher total system factor of safety.
The Stormwater Basins will be "Skimmer" basins, which is a BMP device designed to retain the flow from
a storm event and slowly dewater by skimming the surface water. This basin is 100% effective in
retaining all large particles that maybe suspended in the storm water runoff. It is anticipated that any
particles originating from the stabilized plant yard itself will be relatively large (Fine Sands) and easily
collected in this basin. The remainder of the drainage area at this plant site is unstabilized and
disturbed, which could introduce silts and clays into the runoff. Any silt particles will easily settle out in
this skimmer basin. However, due to the ultra -fine particle size of clays, if introduced into the system
these particles could potentially pass through prior to settling out. Settling time is not realistically
achievable for ultra -fine particles such as clays, and as such the best treatment method for these
particles is to prevent their introduction into the system. This prevention is most easily achieved by
confirming the adequacy of the established ground cover. Any disturbed soil must be vegetated to
eliminate exposed erodible surfaces. Rock "Check Dams" will also be utilized to slow the storm water as
it flows toward the skimmer basin which will also help to reduce the potential risk of erosion.
The Concrete Wash Water will be introduced into its own 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 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 Fortran System will be installed to monitor and regulate the
PH of the wash water.
Predicted Maximums and System Performance
The storm water treatment system has been designed for the Ten Year rain event following the NC
Division of Land Quality Requirements. For the total accumulated drainage areas for this site (7.86 AC,
estimated to be 8.50 AC) the expected flow rate from this storm event would be 49.25 CFS.
The concrete wash water treatment system has been designed for a concrete plant running at a regular
maximum production of 4,000 CY per day. This volume will result in awash water flow of
approximately 4291 CF/D. In actuality, this production rate will only be achieved a limited number of
times on this project. However, it is important to design the waste water treatment system based upon
the project maximums and not the averages.
Upon release from either treatment system (Storm or Wash) 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.

LANE
Maintenance of System
All water treatment devices will be evaluated on a bi-weekly basis, and after any event resulting in 0.5"
of precipitation or greater. 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 property.
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 effectively treat both the Stormwater and the Wastewaters
produced from this concrete plant site. This treatment system has been used successfully at previous
sites for concrete batch plants, most recently this exact plant and treatment methodology was used for
similar NCDOT projects in Cabarrus and Mecklenburg County (Contract Nos. C202522 and C202523).
The rules and guidelines set forth by general permit NCG 140000 will be strictly adhered to and BMP's
will be employed. Any questions regarding the operation of this facility can be directed to the facility
contact noted in the application.
