1 0 INTRODUCTION
11 GENEQnr
This Stormwater Pollution Prevention Plan (SPPP) has been prepared for the VCNA Prestige
Ready Mix facility located at 3107 R3 S Elm Eugene Street in Greensboro, North Carolina The
Prestige Concrete Products facility location is shown on Figure 1 A ready mix concrete plant,
office/maintenance building, material storage areas, closed -loop wastewater treatment system,
and wet detention pond are located on the site The facility intends on demolition and
reconstruction of the existing closed -loop wastewater treatment system, site regrading and
reconstruction of the wet detention pond, and removal of underground storage tanksnd ancillary
equipment including pumps, piping and an oil/water separator (Site Plan C1 1 prepared by Triad
Design Group)
Stormwater discharges from ready -mixed concrete facilities are permitted under North Carolina
Department of Environment and Natural Resources (NCDENR) permit number NCG140000 This
is a general permit to discharge stormwater and authorized process wastewater from ready mixed
concrete facilities (SIC 3273) issued under the National Pollutant Discharge Elimination System
(NPDES)
The general permit to discharge stormwater from ready mixed concrete facilities requires
preparation and implementation of a Stormwater Pollution Prevention Plan The SPPP identifies
potential sources of pollutants and the practices that are to be used to reduce the possibility of
storlm,Y ester,nta,i,ii Iation This SPI^-P has been prepared to address site conditions expected
following construction and is based on site visits conducted on October 11, 2012 and October 24,
2012 by ECS Carolinas, LLP and Site Plan C 1 1 prepared by the Triad Design Group

2 31 General Description
VCNA Prestige Ready Max operates a ready mix concrete production facility at 3107 R3 S Elm
Eugene Street, Greensboro, North Carolina This facility is located on 5 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, vn�7�Q iilg of Sails arld three L] pt* of sLol le, are SLOred In four COrlCrete bins These
bins are three sided concrete structures The aggregate is delivered near the appropriate 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 feedinn hnnnPr that riic�harnAc to an elnira+nil n�nn��ntirnr hnl+ +ham+ nnn r,,,.l,..l a. �1.... a.. s.. -J

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 fillports
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
t 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 conveyed 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 washwater 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 drains to the closed loop recycle system Dry residuals will be sold
The detention pond incorporates a pH adjustment system This system will produce an ettluent
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 either evaporate or flow by overland flow to the wet
detention pond
' The facility has one budding 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 -site disposal

facility Any significant releases that occur will be documented in the following table
Spill Event
2 3 6 Sediment Erosion
Corrective Action I Measures to Prevent
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 earthem materials at the site are expected to have been compacted by tong -term use, if areas
of bare soil are identified 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

' 3 0 STORM WATER MANAGEMENT
' 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 various
measures are discussed below
3 2 SECONDARY CONTAINMENT AND PROCEDURES
' 3 21 Secondary Containment
To prevent leaks and spills from contaminating stormwater, the discharge permit requires
secondary containment for 1) liquid materials stored in bulk, 2) any quantity of a substance
designated as a water priority 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 Tale 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 ranaoty of greater than 660 gallons or multiple ahnV,e-ground Ustoru''',() container] 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 oil
' 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) AlthoUnh the rerpiations
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
0 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 papenvork 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 Facilrty 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

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 monitoring requires visual observation of site stormwater Analytical monitoring
requirements are described in Sections 5 61 through 5 6 3 Qualitative monitoring requirements
are described in Section 5 6 4
' 5 61 Analytical Monitoring Sample Collection
' The permit to discharge stormwater and process wastewater from ready mix concrete facilities
has monrtonng 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 cleanout 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 monitoring of process wastewater apply Analytical
monitoring 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 during each of the following collection periods
SAMPLE COLLECTION PERIOD
Jams 1 to March 31
April 1 to June 30
July 1 to September 30
October 1 to December 31

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 co^.caI, —1;o^s
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 monitoring 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 "
rIn 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 ---veiled to runoff The Striple Method
estimates flow as follows

IA = Impervious fraction (2 23 acres/2 75 acres = 0 8109)
A = Watershed area (acres) = 2 75
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
V(outfall ool) = 0 058228(I), where
I = Total Rainfall (inches)
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 conditons Violation of permit limits twice in a row immediately increases
the monitoring frequency to monthly monitoring for all wastewater parameters After six months 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 permmee 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

5 6 4 Qualitative Monitoring
Semi -Annual Qualitative Monitoring must be conducted twice each year during an analytical
monitoring event The sample collection penods are as follows
MONITORING SCHEDULE
Sample Collection Period
January 1 to June 30
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 dunng 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 ouffall 001
33

Prestige Concrete Products

Qualitative monitoring requires an assessment of color, odor, clarity, floating solids, suspended
solids, foam, oil sheen, erosion or deposition at the outfall and other obvious indicators of
stormwater pollution Qualitative monitoring 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 60 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 VII) A written record of the
Iinvestigation, evaluation and response actions must be kept in the SPPP

Qualitative mo` litoring requirements vary most permits require qualitative monitoring to be
performed dunng a "representative storm event" or during a "measureable stow event," However-,
some permits do not have this requirement. Please refer to these de_ nt!0ns, if annlimhle
A "repmentatave storm event" is a storm event that measures greater than 01 incites of rainfall
and that is preceded by at least 72 hours (3 days) in which no story event measuring greater than
01 inches has occurred Am g)PStdBrm event may einntatlrn tin to l Q r nceroxtnu hr w-s of vary

A'measurable stoma event' is a storm event that results in an actual discharge from the
permitted site outfall The previous measurable storm event must have been at least 72 hours
prior The 72-Maur storm interval does not apply of the perrriittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office
