I SITE INFORMATION
A Site Location This site is located in the City Limits of Greensboro on the West side of
town The address is 114 North Chimney Rock Road This property is located in an
industrial section Trees surround the property on the North and East Beyond the trees is
an industrial area Adjoining the property on the South is an industrial business Chimney
Rock Road is to the West and across the street is a nightclub Water discharged from this
site will enter Horse -pen Creek, a class WS41, NSW water body in the Cape Fear River
Basin
B Site Plan A copy of the site plan is located behind tab marked Plan/Maps
C General Location Map A copy of a portion of the USGS map identifying the
surrounding area can be found behind the Plan/Maps tab
D Narrative Description of Storage Practices The sand and stone are delivered by a
contract hauler and stored in silos and on concrete slabs with tall concrete walls These
materials are sprinkled in order to maintain consistent moisture to prevent fugitive dust
The cement and fly ash are stored in closed silos The cement and the fly ash are
delivered via company owned tanker trucks This material is blown into the silos by
means of pneumatic pressure supplied by the tanker truck Potential dusting is controlled
by dust collectors The chemical admixtures are stored in tanks located in a contained
area There are no fuel tanks on the property All vehicles are fueled off -site The mixer
trucks are loaded under the cement silo with dust collection system controlling any
potential dusting The majority of the traffic area is paved and is cleaned on a regular
basis to help control any fugitive dust and sediment entering the stormwater discharge
The remaining traffic area is treated to control dusting during dry weather At the
completion of deliveries the mixers are rinsed off into a series of settling basins These
basins are cleaned out on an as needed basis and stockpiled for drying to be hauled off site
and used as fill material There is one commingled storm/process water discharge outfall
at this location A second stormwater outfall was added to address potential stormwater
discharges emanating from the East side driveway loop and aggregate storage areas
Discharges from these outfalls will be monitored for compliance in accordance with
permit and discharge requirements

Chimney Rock Road Plant # 103
E List of Significant Spills There have been no significant spills reported at this location
up through the date of this revision Should a leak or spill occur it will be duly noted on
the proper form located behind tab labeled Spills
F Certification of Stormwater Outfalls There are now two recognized outfalls for this
site
OF1 At this outfall the stormwater comingles with process water This outfall is
monitored according to the permit specifications
OF2 is identified as a stormwater outfall, maps and permit modifications acre to be
submitted on/before August 5, 2016 to NCDENR to incorporate these changes
From the time of installation (February 2016) to the submittal period, there lhav been no
observation or evidence of discharge
II. STORMWATER MANAGEMENT PLAN
A Feasibility Study This plant does not operate on a regular basis and his no assigned
personnel It is used as a back-up facility for the other two Greensboro locations
Routine inspections/observations are performed on a weekly basis to verify security,
safety and environmental concerns
Operational 1 Management practices have been adapted to minimize the potential for
stormwater / process water discharges and/or discharges that could potentially exceed
permit limits These are further described below in section C Best Mgmt Practices
This site plan has been modified in order to better control the discharge of water Even at
this expense we were not able to separate the storm and process water at OF due to the
layout of the plant and accompanying buildings OF2 was added to reduce the potential
for overloading of OF1
This retrofit was designed to eliminate possible contamination of storm water as much as
practicable within economic constraints Other areas that have been modified are the
truck wash area along with additional settling basins and concrete paving to direct this
process water into the basins
The admixture tanks are located inside secondary containment The aggregate storage
area is contained on three sides to prevent spillage of material One side was left open in
order to receive and to have excess to the material This aggregate is transferred to the
in -plant storage bins via a front-end loader and conveyor system Cement and fly ash is
being unloaded, stored, and discharged via'a closed system
Care is taken to separate the process water from as much storm water as possible by the
addition of swales and berms This process water goes through a series of settling basins
in order to settle out sediment and a CO2 treatment is used to lower the pH Some of this
water is used for truck washdown and/or reused at the plant for dust control and truck
drum washing
Revised permit 8/17/1 1, 08/03/15
Updated 07/20/16 2

SPPP
Chimney Rock Road Plant # 103
B Secondary Containment Schedule The secondary containment vessel for the liquid
admixtures is presently in place These vessels are equipped with a manually control
dram valve that is secured with a locking mechanism When this area is cleaned it is
recorded on the Secondary Containment Release Report (SCRR) form found behmd the
same named tab Prior to release the water will be visually observed and noted on the
"Secondary Containment Release Report" for color, foam, stain, visible sheen, etc If
uncontaminated it will be released If contaminated it will then be properly contained
and disposed the truck wash liquid is labeled biodegradable and phosphate free
solution, with a pH adjusted to within 6 to 9 standard units All other possible
contaminates are stored inside and not exposed to storm water Records of the releases
from the containment vessel are kept at this site for a period of five years
C Best Management Practices Summary (BMP) Best management practices are
physical, structural or management practices that prevent or reduce pollution of waters of
the state The following is a descrtption of the BMP and storm water controls that are in
place at the Chimney Rock Road facility
a) All plant personnel are assigned specific responsibilities relating to duties in
maintaining the plant site in accordance with permit requirements
b) Process water is channeled from the plant and truck wash areas into a series of
settling basins to allow sediments to settle out This water is being used for truck
washing and to control the dust on the haul roads and other traffic areas
c) Drivers must report any leaks of fuel, hydraulic or other fluids to the plant
manager and fleet maintenance for proper repairs Spills are to be cleaned up
immediately and properly disposed of
d) Rinsing out of the truck mixer drums is kept to a minimum and is to be performed
primarily at the Swing Rd plant or other assigned location When necessary at the
end of the day a maximum of 100 gallons of recycled water is used This water is
discharged into the settling basins
e) A log is maintained in the plant manager's office for inspections, service and
maintenance performed on the dust control system
f) There is very little water that drains from the stockpiles and silos Since this is
clean water that is used to keep the aggregate moist and it flows over washed stone
there should be little if any concern for contamination In fact a lot of this water
will evaporate before it has the potential to leave the site
g) The settling basins are cleaned on a regular scheduled basis The final basin is
maintained so that there is at least a 12-inch freeboard to capture a regular rain
event
h) The pH controller is maintained on a regular basis
i) Sediment removed from the basins is stockpiled so that any drainage will flow
back into the basins After the sediment dries it will be disposed offsite in a proper
manner
j) A rain gauge is available at this facility However, due to the reduced frequency of
operations, precipitation levels will be maintained and available at our Greensboro
Swing Road facility

III SPILL PREVENTION AND RESPONSE PLAN (SPRP)
A Potential Pollutant Sources This site does not meet the EPA requirements for a Spill
Prevention Control and Countermeasure Plan (SPCC) Plan The actions to be taken for spill
prevention and response are based on a proper assessment of potential pollutant sources of the
materials in inventory Liquid admixtures, cement, and fly ash and the mixer trucks pose the
greatest potential for a large spill either by rupture of one of the tanks, a severed supply line,
or by overfilling Truck wash detergent is Mortarman CR650 and Safe Soap II, both
biodegradable and phosphate free There are no polymers, brighteners or solvents used on
site Plant personnel have been trained on the proper way to contain any spill and properly
dispose of this material
B List of Potential Pollutant Sources The most likely sources for contaminates are listed
