Dear Mr Long
ECS Carolinas, LLP (ECS) is pleased to submit the enclosed Stormwater Pollution Prevention
Plan (SPPP) for the VCNA Prestige Ready Mix facility located at 3107 R3 S Elm Eugene Street
in Greensboro, North Carolina This SPPP has been prepared to comply with the North Carolina
General Permit to Discharge Stormwater from ready mix concrete facilities (NCG140000)
issued under the National Pollutant Discharge Elimination System (NPDES)
This Plan does not need to be submitted to the North Carolina Department of Environment and
Natural Resources (NCDENR), but must be maintained at the facility Compliance with the
Stormwater Discharge Permit is contingent on the facility fully implementing the requirements of
this Plan To finalize the Plan, a Corporate Officer, or properly authorized representative, must
sign the Management Certification (Section 1 4) and Stormwater Non -Discharge Certification
Form (Appendix II) Additionally, analytical and qualitative stormwater monitoring (Section 5 6),
and inspections (Sections 5 1) must be conducted In the event stormwater data exceeds the
benchmark values listed in Section 5 6 3, the facility must evaluate the implementation of
additional best management practices as described in Section 3 3
Other activities required for full implementation are summarized in Section 1 2 and 6 0 of the
Plan We appreciate the opportunity to provide our services to you If there are questions
regarding this Plan, or a need for further information, please contact us at [phone] or

2 3 FACILITY DESCRIPTION
2 31 General Description
VCNA Prestige Ready Mix operates a ready mix concrete production facility at 3107 R3 S Elm
Eugene Street, Greensboro, North Carolina This facility is located on b 43 acres Ready mixed
concrete containing water, cement, fly ash, aggregates and supplementary additives is produced
at this site
Cement and fly ash are stored in silos These materials are transported from the delivery truck to
' the silos using a pneumatic system The silos are each vented to a baghouse The bags are
periodically shaken and collected material is returned to the silos
Aggregate, consisting of sand and three types of stone, are stored in four concrete bins These
bins are three sided concrete structures The aggregate is delivered near the appropnate bin by a
dump truck and a front ender loader is used to move the material into the bin As needed in the
concrete production process, aggregate is loaded into the front end loader bucket and placed into
a feeding hopper that discharges to an elevated conveyor belt that uses a radial stacker to feed
one of four elevated bins
Supplementary additives are stored in seven plastic aboveground storage tanks located in the
chemical storage facility The tanks are filled from a commercial transport truck using fdlports
located within the storage facility
A computerized control system is used to produce the required concrete mix When a concrete
mix truck is ready to be filled it is parked under the weigh hopper A shroud surrounds the truck
' feeding hopper and emissions from the filling process are vented to the baghouse
To produce truck -mixed concrete, all of the ingredients are charged to and mixed in the truck
mixer The process begins with the discharge of approximately ninety -percent of the required
water to the truck mixer The required aggregate materials are then fed from the batch plant to
a scale followed by transport on a conveyor belt to the truck mixer Required amounts of
cement and fly ash are weighed on a separate scale system and pneumatically convoyed to the
truck mixer Liquid additives and the remaining water are then pumped to the truck mixer Prior
to leaving the facility, the truck is driven to the wastewater recycle system The truck driver

' uses clean water from a tank located on the truck to clean the truck feeding hopper
Wastewater generated from this cleaning procedure is discharged to the wastewater recycle
system
' The facility has a closed loop recycle system that treats process wastewater generated from
cleaning of external truck surfaces and mixing drum cleaning All cleaning will be conducted in an
' area constructed to discharge to the closed loop recycle system Wastewater flows from the
cleaning pad to a three celled settling basin, with overflow from each cell flowing over a weir to the
next cell The water from the last cell is recycled and used as mixing drum wastewater Based on
storm volume, there may be overflow during storm events If the system overflows, overflow will
flow by overland flow to the facility detention pond
Residuals collected in the closed loop recycle system and the detention pond are periodically
removed to maintain settling capacity Residuals will be removed from each cell of the recycle
system on a weekly basis and as needed from the detention pond Residuals will be placed on
a concrete pad that drams to the closed loop recycle system Dry residuals will be sold
The detention pond incorporates a pH adjustment system This system will produce an effluent
with a pH within the acceptable range and pH adjustment will also cause precipitation of some
component of the dissolved and suspended solids
The facility stores sand and aggregate material in four three sided uncovered concrete bins In
the summer these materials are sprayed with water to reduce their temperature Water from
spraying the sand and aggregate piles will ether evaporate or flow by overland flow to the wet
detention pond
The facility has one building in which the vehicle and equipment maintenance facility, the office,
and the control room are located There are oil storage containers located within the vehicle
and maintenance facility area and two additional aboveground diesel fuel tanks are located in
the vicinity of the concrete plant Debris and trash are stored in one dumpster for subsequent
off -sate disposal

property boundary While the northeast corner of the site drains through a swale that runs along
the northern property boundary with a discharge at the eastern property boundary As industrial
activities are not expected to be performed in those areas, the stormwater outfall that receives
industrial flow will be limited to outfall 001
The stormwater outfall is identified on Figure 2 and located as follows

The portion of South Buffalo Creek that stormwater from this facility is discharged to is listed as an
impaired water on the 303(d) list, based on a fair classification for ecological/biological integrity
benthos (16-11-14-2a South Buffalo Creek from source to McConnell Road)
Ecological/Biological integrity assesses the ability of an aquatic ecosystem to support and
maintain a balanced and indigenous community of organisms having specics composition,
diversity, population densities and functional organization similar to that of reference conditions
2 3 4 Non-Stormwater Discharges
The only allowable point source discharges from this facililty are
Stormwater point source discharges (including discharges from on -site vehicle maintenance
areas) and authonzed process wastewater discharges (i e , process wastewater associated
with vehicle and equipment cleaning, raw material stockpiles, and mixing drum cleanout)
regulated by the NCDENR permit to discharge stormwater and process wastewater from
ready mix concrete facilities,
• Uncontaminated groundwater, foundation drains, air conditioner condensate without added
chemicals, springs, discharges of uncontaminated potable water, waterline and fire hydrant
fleshings, water from footing drains, water from riparian habitats and wetlands, and
• Discharges resulting from fire -fighting or fire -fighting training
Stormwater outfalls must be evaluated annually for the presence of unpermitted non-stormwater
' discharges To confirm the absence of non-stormwater flow to the stormwater system, a visual
inspection of the stormwater conveyance during penods of dry weather must be conducted The
source of any water observed in the stormwater conveyance system during periods of dry
' weather must be identified If the observed water is not from one of the allowable discharge
sources described above, the discharge must be halted or properly permitted Forms contained
in Appendix III must be completed to certify that the outfall has been evaluated for the presence

2 3 5 Spill History
During the past three years there have been no significant spills or releases reported at this
facility Any significant releases that occur will be documented in the following table
Spill Event Corrective Action I Measures to Prevent
Reoccurrence
2 3.6 Sediment Erosion
The Prestige Concrete site is 5 43 acres Following demolition and construction activities there
will be 3 0 acres with impermeable surfaces The impermeable surfaces are covered with gravel,
asphalt, concrete or buildings The drainage area that receives industrial flow and discharges to
the retention pond is 2 75 acres, of which 2 33 acres are impermeable surfaces
Eroded areas that can contribute to sediment loading were not identified during the site visit
Based on facility operations, there is the potential for the gravel surface to be displaced Although
the earthern materials at the site are expected to have been compacted by long-term use, if areas
of bare soil are identrfied in the future they should be covered with gravel
The construction activities to be conducted at this facility will disturb 125 acres Construction
activities that disturb more than one acre require a stormwater permit issued by the NCDENR or a
delegated local regulatory agency The stormwater permit requires development and
implementation of a project specific Erosion Control Plan As this project does not increase the
built -upon areas, the delegated local authority, the City of Greensboro, does not require
submission of an Erosion Control Plan An Erosion Control Plan for the proposed construction
project has, however, been prepared and will be submitted to the NCDENR
' If additional construction activities are considered in the future, prior to initiating such activity
erosion control measures must be identified Larger construction activities conducted by outside
contractors require inclusion of project -specific erosion control measures as part of the contracted
' activities The necessity for erosion control activities for facility conducted activities will be
dependent on the project size, duration and location Projects conducted by facility personnel
which disturb small areas may only require limited erosion control measures which may include

i dust control, sediment control and/or stabilization measures Dust control activities may include
sprinkling, irrigation or placement of ground cover Sediment control measures may irclude
installation of silt fences or berms As with dust control, stabilization of soil following construction
i would require placement of ground cover Placement of ground cover may include installation of
mulch, hay, stone, vegetation, geotextrle material, chemical soil treatments such as asphalt or
latex emulsions, or impervious surfaces such as asphalt of concrete Erosion control measures

31 FEASIBILITY
Wherever practical, the facility must prevent or minimize exposure of all storage areas, material
handling operations and vehicle/equipment maintenance and fueling operations Due to the nature
of some of the facility activities, it is neither economically feasible nor operationally practical to
cover or contain all operations In such cases, efforts should be made to limit run-on and run-off in
areas where materials are exposed to stormwater The feasibility and constraints of vanous
measures are discussed below
3 2 SECONDARY CONTAINMENT AND PROCEDURES
3 2 1 Secondary Containment
' To prevent leaks and spills from contaminating stormwater, the discharge permit requires
secondary containment for 1) liquid materials stored ,n bulk, 2) any quantity of a substance
designated as a water pnorrty chemical by Section 313 of Title III of the Superfund Amendments
' and Reauthorization Act, and 3) any quantity of a substance designated as hazardous under the
Code of Federal Regulations Title 40, Part 116
' There is bulk storage of liquid materials at this facility, but substances designated as water
priority chemicals or Part 116 hazardous substances are not expected to be stored at this
facility Concrete production additives are stored in four 925-gallon ASTs and three 525-gallon
' chemical ASTs, with occasional additional storage in totes Petroleum products are stored in
bulk at the site in aboveground storage tanks, drums, vehicle reservoirs and small containers
' Bulk storage is defined by the stormwater permit as a single above -ground storage container
having a capacity of greater than 660 gallons or multiple above -ground storage containers of a
substance located in close proximity to each other with a total combined storage capacity of
' greater than 1,320 gallons
The Oil Pollution Prevention Regulation addresses facilities with an aggregate aboveground owl
storage capacity exceeding 1,320 gallons This regulation requires secondary containment for oil
storage containers with a capacity greater than or equal to fifty-five gallons Vehicle tanks
(trucks, loaders, etc ) used to hold fuels or fluids required to operate the vehicle are not
' required by the Oil Pollution Prevention Regulations to have secondary containment
Both the stormwater discharge permit and the Oil Pollution Prevention Regulations require
secondary containment provide sufficient capacity for the largest single tank within the
' containment area and sufficient freeboard for precipitation (if exposed) Although the regulations
do not set a standard for `sufficient" freeboard, the EPA recommends sufficient freeboard for a
25-year, 24-hour storm event For the site, a 25-year storm event is 5 65 inches The USEPA has
accepted shop built double -walled tanks as an equivalent preventative system of secondary
containment Containment for precipitation will not be required for containers not exposed to

' 3 2 2 Secondary Containment Drainage Procedures
Released material collected in the chemical storage containment tank well be pumped out by a
' waste disposal contractor and treated or disposed of off -site Disposal manifests or other
transporter provided paperwork will serve as documentation of this activity
' The Prestige Concrete facility does not have containment structures, such as dikes, that collect
stormwater In the event of an unexpected leak resulting in the presence of water in a
containment area, the procedure for containment area drainage is as follows
1 The Facility Manager or designated representative must visually observe standing water
for evidence of oil, sheen, color, or foam and determine if water may be drained
2 If evidence of contamination is not observed, the drainage valve (if present) may be
unlocked and the water may be drained, or the water may be pumped out
3 If evidence of contamination is observed, inspect the tanks, containers and/or equipment
for leaks Estimate the quantity of water to be discharged Obtain a water sample if
necessary Arrange for proper disposal of the water
4 Close and lock the drainage valve (if present) after drainage is completed
5 Document visual inspection and water removal on forms contained in Appendix IV
3 3 BEST MANAGEMENT PRACTICES
Best Management Practices (BMPs) are structural and non-structural measures employed to
control or minimize the exposure of significant materials to stormwater Operational BMPs are
practices and procedures designed to prevent the introduction of pollutants to stormwater
Structural BMPs are physical structures designed to prevent the introduction of pollutants into
stormwater or to remove pollutants from stormwater

Spills or releases, excluding minor spills within containment areas, must be immediately reported
to the Facility Manager For larger releases with the potential to impact drainage ways, surface
waters or stormwater, the General Manager is responsible for documentation and reporting to
regulatory agencies The response to spills, and the degree of documentation and reporting, is
dependent on the magnitude of the spill and the potential impact to the environment Fully
contained spills that do not threaten the environment may not require official reporting All
releases must be addressed immediately by following the procedures contained in Section 4 4
The NCDENR Winston-Salem Regional Office (336-771-5000) or Central Office (800-858-0368)
must be notified in the event of any stormwater permit noncompliance that may endanger health
or the environment Noncompliance includes, but is not limited to, spills and releases Verbal
notification must be provided within twenty-four hours of the time that the permrttee became aware
of the circumstances Written notification must be submitted within five days The written
submission must contain
• A description of the noncompliance and its causes,
The period of noncompliance, including exact dates and times, and,
• If the noncompliance has not been corrected, the anticipated time it is expected to
continue, and steps taken or planned, to reduce, eliminate and prevent reoccurrence of
the noncompliance
' Permit noncompliance that does not endanger health or the environment must be documented
and the documentation included with monitoring report submissions
' The United States Environmental Protection Agency (USEPA) National Response Center (NRC
- 24-hr number 80"24-8802) and the North Carolina Department of Environment and
Natural Resources (NCDENR — 24 hr number 800-858-0368) must both be notified in the
event of a discharge of petroleum products into a navigable waterway (e g , drainage ditch,
creek, pond, etc) which
' 1 produces a film, sheen, discoloration, or causes a sludge or emulsion to be deposited
onto adjacent shorelines, or
2 causes water quality standards to be violated (i e , generally any discharge which
reaches water)
Additionally, the NCDENR must also be notified of a spill of petroleum products, if
1 The spill is 25 gallons or more (even if spill does not reach a waterway), or

5 6 MONITORING AND REPORTING REQUIREMENTS
The facility is required to conduct analytical monitoring and qualitative monitoring of stormwater
discharges Analytical monitoring requires sample collection followed by laboratory analyses
Qualitative monrtonng requires visual observation of site stormwater Analytical monrtonng
requirements are described in Sections 5 61 through 5 6 3 Qualitative monitoring requirements
are described in Section 5 6 4
b 6 1 ,Analytical Monitoring Sample Collection
' The permit to discharge stormwater and process wastewater from ready mix concrete facilities
has monitoring requirements specific to the type of stormwater or wastewater discharged The
permit categorizes facility discharges as follows
1 Stormwater that is not commingled with process wastewater,
2 Stormwater from vehicle maintenance areas that is not commingled with process
wastewater, and,
3 Process wastewater associated with rinsing the external surfaces of vehicle and
equipment, wetting of raw material stockpiles, and mixing drum cleanout, including
commingled stormwater and/or stormwater from vehicle maintenance areas
The Prestige Ready Mix facility has one point source discharge from industrial operations at the
facility consisting of overflow from the detention pond (outfall 001) Facility stormwater and
process wastewater from wetting raw material stockpiles flow directly to the detention pond, as
does stormwater from the vehicle maintenance area Wastewater generated from vehicle and
equipment cleaning and mixing drum cleanout is treated in a closed loop recycle system and
reused for mixing drum cleanoi t In the event the closed loop recycle system overflows, water
discharged from that system would also flow to the detention pond
Since the discharge from outfall 001 will consist of process wastewater commingled with
stormwater, the requirements for analytical monitonng of process wastewater apply Analytical
monitonng for process wastewater must be conducted four times per year, with an increased
frequency if laboratory analytical results exceed permit limits or benchmark values Samples must
be collected dunng each of the following collection periods
SAMPLE COLLECTION PERIOD
January 1 to March 31
40 1 to June 30
_ July 1 to September 30
j October 1 to December 31

If the facility fails to perform quarterly monitoring, the analytical monitoring requirement
immediately increases to monthly monitoring After six months of monthly monitoring, the
monitoring requirement reverts to quarterly monitonng, unless the NCDENR Division of Water
Quality requires continued monthly monitoring
As samples from outfall 001 are considered process wastewater, they must be analyzed for the
parameters listed in the following table Flow from outfall 001 is expected to occur only during
precipitation events Samples collected during precipitation events must be collected during the
first 30 minutes of discharge from outfall 001

' For each analytical monitoring event, the total discharge duration and total precipitation must be
recorded and the total flow must be calculated or measured Samples must be analyzed for pH,
total suspended solids (TSS), settleable solids and total petroleum hydrocarbon concentrations
The NCDENR requires pH be analyzed within fifteen minutes of sample collection using a
calibrated meter which meets NCDENR specifications
5 6 2 Analytical Monitoring Reporting
The laboratory analytical results must be entered onto a discharge monrtonng report (DMR —
' Appendix IX) The DMR must be submitted to the NCDENR within thirty days of receipt of data
from the laboratory If no discharge occurs during a sampling period, the monitoring report must
be submitted within thirty days of the end of the monitoring period with the statement "no flow "
In addition to the results of laboratory analyses, the DMR requires reporting of the total discharge
duration (minutes) and total flow (gallons) The facility must install a rain gauge and estimate
discharge duration for each monitored stormwater event As discussed below, the Simple Method
may be used for estimating stormwater flow from outfall 001
The Simple Method calculates the runoff from a watershed based on a relationship between the
' percent of impervious area and the amount of rainfall converted to runoff The Simple Method
estimates flow as follows

The DMR requires flow (V) be reported in million gallons Based on the Simple Method, the flow
in million gallons would be calculated by multiplying the following
IV(cutfali ool) = 0 058228(I), where
I = Total Rainfall (inches)
1 V = Stormwater Flow (MGD)
5 6 3 Effluent Limits and Benchmark Values
■ Wastewater discharges from outall 001 are subject to the effluent limits for process wastewater
discharges listed in the following table An exceedence of any of these limitations will result in a
' violation of the permit conditions Violation of permit limits twice in a row immediately increases
the monitonng frequency to monthly monitoring for all wastewater parameters After six months of

TIER THREE BENCHMARK VALUES RESPONSE ACTIONS
If sampling results for total petroleum hydrocarbons exceed the benchmark on any four
occasions during the term of the permit, the permittee must notify the NCDENR Division of
Water Quality (DWQ) Regional Office Supervisor in writing within thirty days of the receipt of
the fourth analytical result DWQ may take, but is not limited to, the following actions
• Require that the permittee revise, increase, or decrease the monitoring frequency for
the remainder of the permit,
• Rescind coverage under the General Permit, and require that the permittee apply for an
individual stormwater permit,
Require the permittee to install structural stormwater controls,
• Require the permittee to implement other stormwater control measures,
• Require the pemittee implement site modifications to qualify for the No Exposure
Exclusion, or
• Require the permittee to perform upstream and downstream monitoring to characterize
impacts on the receiving waterbody
5 6 4 Qualitative Monitoring
Semi -Annual Qualitative Monitoring must be conducted twice each year during an analytical
monitoring event The sample collection periods are as follows
MONITORING SCHEDULE
Sample Collection Period
January 1 to June 3.0
July 1 to December 31
A minimum of sixty days must separate each monitoring event For qualitative monitoring,
sampling is conducted by collecting a grab sample at each permitted outfall during a "measurable
storm event" A "measurable storm event" is a storm event that results in an actual discharge
from the permitted site outfall, and occurs at least 72 hours after the previously measurable storm
event The samples must be collected during the first 30 minutes of discharge from outfall 001
33

Prestige Concrete Products
Stormwater Pollution Prevention Plan
ECS Project 09-21436
December 6, 2012
Qualdative monrtonng requires an assessment of color, odor, clanty, floating soilds, suspended
solids, foam, oil sheen, erosion or deposition at the outfall and other obvious indicators of
stormwater pollution Qualitative morntonng must be documented on forms contained in Appendix
IX Completed forms must be maintained on -site with the Plan
If qualitative monitoring indicates existing stormwater BMPs are ineffective or significant
stormwater contamination is present, the permittee must investigate causes, evaluate the
' feasibility of corrective actions and implement corrective actions within 68 days This investigation
may be conducted using the general sections of the Comprehensive Site Compliance Evaluation
and the sections applicable to the outfall of concern (Appendix VIO A written record of the
1 investigation, evaluation and response actions must be kept in the SPPP
If the permftee repeatedly fails to respond effectively to correct problems identified by qualitative

6 0 ITEMS OF CONCERN
1 There is inadequate secondary containment for the additive tanks The chemical storage
' facility does not provide containment for the contents of the largest tank
2 There is inadequate secondary containment for the oil tanks located within the
maintenance facilrty The single walled steel tanks are located within a building with floor
drams that discharge outdoors These tanks require secondary containment The facility
intends on providing secondary containment by replacing the existing tanks with double -
walled tanks
3 In the event of a release, facildy employees must initiate containment activities The
facility must maintain adequate supplies for clean up of minor spills and initial
containment of larger releases To appropriately perform these activities, spill response
equipment consisting of protective equipment and absorbent socks, pillows, or pads
must be maintained Spill response equipment is currently stored within the
maintenance facility To allow a release to be quickly addressed, spill response
equipment must also be stored in the vicinity of the diesel fuel ASTs and the chemical
' storage facility
