Attachments: CNCG140427-NOI.pdf3
Hi Danny,
Attached is an NOI application from Eagle Rock Concrete, LLC for a new facility in Wake County (Apex). The company is
requesting coverage under NCG14 stormwater+ wastewater general permit.
They will discharge stormwater to a UT to Middle Creek (Class C;NSW) in the Neuse Basin. Operation was scheduled to
begin in June 2013, but I'm behind on these. I'm not sure of the status of the site. They have proposed a non -discharge
recycle system for all the process wastewater, including aggregate spray down. The NOI and plans indicate they would
pursue a non -discharge permit, but Jon Risgaard in APS says they haven't seen anything from these guys. I will follow up
with the consultant about it today or tomorrow.
The plans were prepared by Withers & Ravenel (Dale Werenko, P.E.), and they're pretty decent. I'm attaching the NO[,
and I'll forward a copy of the plan sheets to the RRO (to Dave Parnell's attention, if that's okay). Please let us know if
the Raleigh Regional Office have any concerns with issuing a COC for this site.
Normally we'll plan to issue the COC if we don't hear from you in 30 days, but we wait on NCG14 and NCG02 permits
until we have confirmation from the regional office. Thanks for your help with this one.
Thanks,
Bethany

Subject: Notification of a ready -mix concrete plant start up
Hi Autumn,
I took a call from Dexter Tart, Eagle Rock Concrete on Tuesday. He was calling to fulfill his obligation under a new CDC
for NCG14 to invite DWQ out for a site visit prior to start up of his facility on Friday (tomorrow.) I advised that he should
have called FRO, but based on my past contact and professional friendship with him, I would relay the message to RRO.
I got distracted and forgot to forward the information to you. My apologies for this late contact.
NCG140425, 6301 Mt. Herman Rd, Raleigh. Dexter reports that they will be handling their wastewater with a recycle
system, but they still have a stormwater-only discharge. I declined his invitation tome for a visit on Friday, but did note
that I would be interested in visiting the facility some other time in the near future, as he seemed pretty proud of it.
This is a start-up company, and Dexter is participating in the ownership of it. Robert permitted the facility, and I've
copied him on this note for that reason.
Again, my apologies for this late notification. I've looked at the plans, and don't imagine that there will be any risk of a
wastewater discharge from their non -discharge recycle system (five settling bins). The CDC was issued for a
stormwater-only discharge. Dexter is a knowledgeable guy wrt stormwater and wastewater discharges after many years
in the ready -mix industry, and the design was by Withers & Ravenel. I'm pretty confident that there won't be any gross
misunderstanding as to the purpose and function of the stormwater and wastewater systems.
If you are interested in making the visit in spite of my late notification, then here is Dexter's cell phone: [phone].
Sorry for the late notification.

NCG140000 Application —
Alliance Concrete Company - Zebulon
Application Return (Return #1154)
Wake County
On August 24, 2007, the Division of Water Quality received your Notice of Intent (NOI)
requesting coverage and an Authorization to Operate (ATO) under general stormwater and
wastewater permit NCG 140000. After preliminary review, the Stormwater Permitting Unit
(SPU) has determined the submitted materials are insufficient for us to continue processing this
application. The deficiencies are explained below to help you resubmit a complete application.
Plans/Specifications for Treatment Facilities As -Built or Detailed Diagram of
Treatment Systems: No diagrams or specifications were provided for the retention pond.
Please provide more detailed information about this treatment system (see Page 3 of the
NOI application —Wastewater Treatment Design Information pertaining to existing
sites.) For example, there is no information about depth, sides slopes, emergency
spillway location (if there is one), height of the berm or what type of berm, etc. Please
provide as much information about the retention pond structure as -built as possible.
2. Design Calculations and Assumptions
a. There is no information about how much truck wash water is put into the basin on
a daily basis. What amount of water will vehicle washings (and other inputs)
contribute daily, and what are the assumptions (e.g., maximum number of trucks,
amount of water per truck, etc.)? What is the operating water depth? (In other
words, how much water is likely to be present at the time of rainfall?)
b. The application indicated the pond will overflow only in a very large storm event
and had no identifiable discharge; however, there was no information about the
drainage area into the pond, and no engineering calculations to demonstrate the
runoff volume that can be contained. How much runoff can the basin hold before
overflowing, and what size storm event does that reflect? (The estimate should
take into account volume occupied by truck wash inputs). Please provide rung5hCaroIina
calculations, and clearly state the assumptions. ,Natural(;

C. At what level are solids cleaned out of the retention pond to ensure sufficient
treatment volume and settling time is available?
d. The application requires a demonstration of compliance with total suspended
solids (TSS) and settleable solids (SS) permit wastewater limits (see question 14.
.on the NOI application form). Please provide calculations that show settling and
retention time are sufficient to meet TSS and SS effluent limits in the event of a
discharge. If these calculations are not provided, we may accept the application
as complete if it demonstrates all wastewater in the pond can be recycled,
withdrawn and disposed properly, and/or will infiltrate or evaporate at a rate to
maintain 1 foot of freeboard and volume enough to contain runoff from the 25-
year, 24-hour storm event.
3. pH Adjustment: There is no pH -adjustment system indicated on the site plan. Please
provide information about how pH is controlled in the event of retention pond overflow.
The return of this application does not affect the legal requirements to obtain other
permits which may be required by the Division of Water Quality or pennits required by the
Division of Land Resources, Coastal Area Management Act or any other federal or local
governmental permit or approval that may be required. Please be advised that on September 1,
2007, the application fee for a general permit increased to $100.00.
The NOI application is being returned to you with this letter. If you have any questions
concerning this matter, please contact Bethany Georgoulias at [phone], extension 529.

i.i PURPOSE & SCOPE OF SPCC PLAN
(40 CFR Part 112)
§112.1 —3 General Applicability Requirements forSPCCPlan
The Federal Pollution Control Act (a.k.a., Clean Water Act) mandated regulations for the prevention
of oil spills into the navigable waters of the United States. The Federal oil pollution prevention
regulations were promulgated on December 11, 1973 and came to be known as the Spill Prevention,
Control and Countermeasures (SPCC) regulations (4o CFR 112 Oil Pollution Prevention). The United
States Environmental Protection Agency (EPA) has been charged with the responsibility of
implementation and enforcement of the SPCC regulations. The regulation established spill
prevention procedures, methods and equipment requirements for non -transportation related
facilities with aboveground oil storage capacity greater than 1,320 gallons, or buried underground
oil storage capacity greater than 42,000 gallons. The regulation requires that the SPCC Plan must be
certified by a registered professional engineer.
The SPCC Plan is intended to represent a detailed facility -specific description of how a facility's
operations comply with the pollution prevention guidelines. The guidelines include measures for
secondary containment, facility drainage, dikes or barriers, sump and collection systems, retention
ponds, curbing, tank corrosion protection systems and liquid level devices. Facilities must
implement the plan including carrying out the spill prevention and control measures established for
the type of facility or operations. The SPCC Plan is not submitted to a regulatory agency for review
unless repeated spills occur on site (see §112.5).
A SPCC Plan has been prepared for the City of Raleigh E.M. Johnson Water Treatment Plant Raw
® Water Pumping Station because one 30,000-gallon underground storage tank (UST) system is
located on site. The UST is used for the storage of No. z fuel oil as a source of fuel for the emergency
generators on site. A spill of fuel oil during tanker offloading in the vicinity of the UST and
emergency generator systems could flow into the adjacent storm drain system and discharge to Falls
Lake.
The SPCC Plan has been prepared for this site to provide the City with an analyses of potential oil
spills. The SPCC regulation only requires SPCC Plans for facilities storing in excess of42,000 gallons
of fuel in UST systems.
The plan must also address:
(i) The type of oil in each container and its storage capacity;
(ii) Discharge prevention measures including procedures for routine handling of products (loading,
unloading, and facility transfers, etc.);
(iii)Discharge or drainage controls such as secondary containment around containers and other
structures, equipment and procedures for the control of a discharge;
(iv) Countermeasures for discharge discovery, response and cleanup (both the facility's capability
and those that might be required of a contractor);
(v) Methods of disposal of recovered materials in accordance with applicable legal requirements;
and
(vi) Contact list and phone numbers for the facility response coordinator, National Response Center,
® cleanup contractors with whom the City has an agreement for response, and all appropriate Federal,
State and local agencies who must be contacted in the case of a discharge.
EM Johnson Water Treatment Plant — Raw Water Pumping Station Page 1-2
SPCC Plan

§II2.4 Amendment of SPCC Plan By EPA RegionalAdministrator
An EPA Regional Administrator (RA) may require the SPCC Plan be amended following a single
discharge at the facility in excess of 1,000 gallons or following two discharges within any twelve-
month period that exceed 42 gallons per event. The owner must submit the SPCC Plan to the RA and
the local state agency (Division of Water Quality) within 6o days following the release.
The RA, following review of the SPCC Plan, may inform the City that amendments to the Plan are
proposed as deemed necessary to prevent any future discharges. A rebuttal process is allowed by
the EPA in this circumstance. All amendments must be incorporated into the SPCC Plan within 30
days following final notification by the RA.
§112.5 Amendment of SPCCPlan By Owner or Operators
The City must review the SPCC Plan at least once every five years and amend the SPCC Plan (if
necessary) within 6 months following review. Amendments are required to incorporate more
effective control and prevention technologies if the technology will significantly reduce the
likelihood of a release (and is field proven).
The City must also amend the SPCC Plan whenever there is a change in facility design, construction,
operation or maintenance that materially effects the facility's potential for discharge into navigable
waters or adjoining shorelines. As recommendations outlined within this report are constructed, this
SPCC Plan will require amending.
The review by City Management should be documented in the SPCC Plan. A review with no changes
10 may be signed by Management. Amendments to the SPCC Plan must be certified by a Professional
Engineer only when changes to equipment arrangement, location or practices occurs.

1.4 OIL SPILL HISTORY
(NEED INFORMATION FROM CITY OF RALEIGH)
40 CFR Part 112.7 (a) requires that "A facility which has experienced one or more spill events within
twelve months prior to the effective date of this part should include a written description of each
such spill, corrective action taken and plans for preventing recurrence."
W&R understands that the City has had no significant spills of petroleum at this location.
1.5 Petroleum Storage & Distribution Facilities
Review of the petroleum storage and distribution facilities at the Raw Water Pumping Station
followed the requirements of 40 CFR Part 112.7.
1.5.1 Security
40 CFR Part 112.7 (g) specifies the following concerning site security (portions of the applicable
regulation appear in italics):
1.5.1.1 Fencing / Restriction of Site Access
(1) Fully fence each facility handling processing, or storing oil and lock and/or guard
entrance gates when the facility is not in production or is unattended.
The Raw Water Pumping Station is within a security fence with gated access. Currently,
vehicular traffic only enters through the main gate of the facility. All vehicles use the
same entrance. The facility is visited on a daily basis by plant operators. Otherwise the
facility is unmanned.
1.5.2.2 Drain Valves / Oil Pumps
(2) Ensure that the master flow and drain valves and any other valves permitting direct
outward flow of the container's contents to the surface have adequate security measures
so that they remain in the closed position when in non -operating ornon-standby status.
The hydraulic oil AST is located within the pump station building. The tank appears to
only store several hundred gallons of hydraulic oil. A section of raised concrete curb is
positioned around the AST within the pump station building. The bulk storage AST
containing hydraulic oil has a bottom mounted drain valve.
No fuel dispensing for vehicle fueling or tanker loading occurs at the site. Oil pumps are
positioned on the generators and are piped in a closed loop fashion between the UST
and the four emergency generators with supply and return piping.
EM Johnson Water Treatment Plant -Raw Water Pumping Station Page 1-9
SPCC Plan

0 1.5.1.3 Loading / Unloading Connections of Oil Pipelines / Facility Piping
u
(3) Lock the starter control on each oil pump in the "ot?" position and locate it at a site
accessible only to authorized personnel when the pump is in a non -operating or non -
standby status.
(4) Securely cap or blank flange the loading/unloading connections of oil pipelines or
facility piping when not in service or when in standby service for an extended time. This
security practice also applies to piping that is emptied of liquid content either by
draining or by inert gas pressure.
Fuel is transferred from the tank truck to the 30,000 gallon UST using the pump mounted
on the fuel tank truck. The fill piping for the 30,000 gallon UST is located in a grassed
area. The "fill" end of the piping is positioned within a secondary containment bucket.
The end of the pipe is configured with a quick disconnect coupling with a cap.
Product lines between the UST and the generator building appears to be directly buried
metal piping. The lines were only visible inside the generator building. If secondary
containment was available for the piping, it was not apparent during the site visit.
Fuel piping in the building is sweated copper piping. The piping is configured as a
supply and return manifold. It appears that all four generators are connected to the
supply and return fuel manifold rather than use the existing day tanks that are present
for three of the four generators within the building.
Hydraulic oil piping is routed above grade from the pump station building to the two
valve pits. The piping is installed within a secondary containment pipe inside the pump
station building. The welded copper piping carries fuel from the AST under pressure to
the actuators on valves in each valve pit.
1.5.1.4 Recommendation
The piping between the UST and the generator building should be replaced with piping
within secondary containment. The piping connection to the AST should be installed
within a liquid tight vault with a high level alarm. The existing piping should be pressure
tested to confirm that a release has not occurred in this location.
EM Johnson Water Treatment Plant —Raw Water Pumping Station Page i-io
SPCC Plan

® 1.5.1.5 Facility Lighting
11
(5) Provide facility lighting commensurate with the type and location of the facility that
will assist in the:
(i) Discovery of discharges occurring during hours of darkness, both by operating
personnel, if present, and by non -operating personnel (the general public, local police,
etc.); and
(ii) Prevention of discharges occurring through acts of vandalism
Exterior lighting is present in proximity to the pump station building. Fuel oil delivery is
limited to day light hours only and is attended by a City of Raleigh employee.
2.5.1.6 Recommendation
Lighting should be observed in the vicinity of the No. z fuel oil storage and offloading
areas, the emergency generators and the pump station building. The lighting should be
supplemented if the ground immediately surrounding these facilities is not clearly
illuminated during the evening hours (i.e. darkness). It is important that any potential
evidence of a release such as the overland flow of fuel is easily observed by plant
personnel so that any source of a fuel spill can be identified and corrected.
1.5.2 Facility Tank Truck Loading / Unloading Rack
qo CFR Part 112.7 (h) specifies the following concerning tanker offloading:
(1) Where loading/ unloading area drainage does not flow into a catchment basin or
treatment facility designed to handle discharges, use a quick drainage system for
tank car or tank truck loading and unloading areas. You must design any
containment system to hold at least the maximum capacity of any single
compartment of tank car or tank truck loaded or unloaded at the facility.
(a) Provide an interlocked warning light orphysicatbarriersystem, wamingsigns, wheel
chocks or vehicle brake interlock system in loading/unloading areas to prevent
vehicles from departingbefore complete disconnection offtexible or fixed oil transfer
tines.
(3) Prior to filling and departure of any tank car or tank truck, closely inspect for
discharges the lower most drain and all outlets of such vehicles, and if necessary,
ensure that they are tightened, adjusted, or replaced to prevent liquid discharge
while in transit.
EM Johnson Water Treatment Plant -Raw Water Pumping Station Page ru
SPCC Plan

® Tanker offloading occurs along the asphalt driveway near the pump station building. No
secondary containment structure is provided for tanker offloading. A speed bump is
installed across the driveway to deter flow from into the tanker offloading area from the
adjacent parking lot. During tanker offloading, a spill prevention mat is placed on each
stormwater catch basin within the fenced compound to prevent a spill from entering the
storm drain system.
The tanker offloads fuel in a paved parking lot of the facility. Curb and gutter is present
along the perimeter of the asphalt driveway. No secondary containment structure is
available for the tanker offloading.
1.5.2.1 Spill Potential, Rate & Direction
Fuel Oil - Tanker Offloading
A spill of No. z fuel oil is most likely during offloading of fuel oil during tank truck
offloading. The spill could occur by failure of the tanker hose or hose connection to
tanker or UST, overfill of the UST, or failure of the tanker. A spill in this fashion would
enter the asphalt paved parking lot and follow the established grade to the nearest
storm water catch basin. A spill on the south side of the building would be contained
within the paved asphalt area, defined by the speed bump, curb and gutter, and the
building, IF the spill prevention mat placed over the storm drain is liquid tight.
The storm water catch basins on either side of the pump station discharge directly to
Falls Lake. If fuel passes by the spill prevention mats, then the fuel will enter the Lake.
10 Figure z shows the potential path of the spill migration.
Fuel Oil - Generator Piping Loop Outside Building)
Fuel oil is routed between the AST and the generator building via direct buried piping. A
portion of the piping is buried beneath asphalt pavement and the building pad. The
remainder of the piping is buried beneath the lawn. The piping enters the building
through the concrete slab and is routed above grade to each of the four generators.
Failure of a supply or return line outside the building has the potential to surface in the
lawn or joint in the pavement and flow above grade (or below grade) and enter the
adjacent storm drain system and ultimately Falls Lake. The entire contents of the UST,
30,000-gallons, could be released if a return line failure occurs.
Fuel Oil - Generator Loop Piping (Inside Building)
Fuel oil released within the building should enter the trench drain system in the building.
The trench drain flows to a manhole outside the building. A valve is present on the
trench drain pipe at the manhole. This valve was open at the time of the site visit. Flow
from the manhole enters a spill containment vault positioned outside the building.
The spill containment vault has a capacity of approximately 4,600 gallons. The elevation
of the rim of the vault appears higher than the manhole or the finished floor of the
® generator building. A large scale spill in the generator building could exceed the
EM Johnson Water Treatment Plant - Raw Water Pumping Station Page 1-12
SPCC Plan

® capacity of the vault or cause fuel to back up in the manhole and trench drain and Flow
overland to the nearest storm water catch basin.
A failure of the return fuel manifold for the generators could allow the majority of the fuel
from the UST (3o,000 gallons), to discharge into the trench drain and ultimately to the
storm sewer system.
Hydraulic oil
Hydraulic oil storage and distribution equipment is installed in almost all cases within a
curbed area within the pump station building or the two valve pits (which have inherent
secondary containment). Hydraulic oil is stored in an AST and reservoir system. The oil
is circulated under pressure to cone valves in the two valve pits. A set of copper oil
supply and return lines are present for each valve pit.
A spill within the pump station building will likely enter the curbed area around the
hydraulic oil AST. The curbed area has a capacity of approximately 151 gallons. The
hydraulic oil AST and reservoir system will hold approximately 690 gallons if operated in
a full condition. At the time of the site visit, the hydraulic oil level in the AST and
reservoir system was only io to 12 inches. This appears to be the normal hydraulic oil
level and equates to a volume of 207 gallons. The volume of oil in the distribution
system (piping, cylinders, etc.) is unknown. However, it is apparent that the combined
storage and distribution volume exceeds the storage capacity of the curbed area.
A spill of oil within the valve pits will accumulate within the pit. Water in the pit is
removed by a dedicated sump pump that is manually operated. The sump pump may
discharge to Falls Lake or the spill containment vault positioned outside the pump
station building. The operator makes the decision on where to send the water from the
pit. Water containing oil is pumped to the vault. Clean water is pumped to the Lake.
1.5.2.2 Recommendation
The above referenced regulation specifies that a secondary containment structure be
constructed for tanker offloading. The design should incorporate a physical barrier
system to prevent tanker driveoffs until all hoses, etc. are properly disconnected. The
plant should incorporate procedures for offloading of fuel and post offloading
inspections of the tanker for leaks, etc.
EM Johnson Water Treatment Plant - Raw Water Pumping Station Page 1-13

0 1.5.3 Brittle Fracture Evaluation
0
(i) if a field -constructed aboveground container undergoes a repair, alteration, reconstruction,
or a change in service that might affect the risk of a discharge or failure due to brittle fracture
failure or other catastrophe, evaluate the container for risk of discharge or failure due to brittle
fracture or other catastrophe, and as necessary take appropriate action.
No field constructed above ground containers for petroleum motor fuels are present at the
facility.
1.5.4 Deviation Rule
The facility must comply with all applicable requirements listed in 40 CFR 112.7 (g) security, (h)
(z) and (h) (3) vehicle loading / loading procedures, and (i) brittle fracture evaluation or
Subparts B and C (except secondary containment). The plan must:
State the reasons for non-conformance
Describe in detail alternate methods / how equivalent environmental protection will
be achieved.
The facility is in general compliance with the above cited regulations. A maintenance
department employee reportedly accompanies all tank truck offloading activities. However, no
interlocked warning light or physical barrier system is being utilized.
1.541 Recommendation
The City of Raleigh should implement a simple physical barrier system to integrate into
the tank truck offloading procedures. The EM Johnson employee supervising the
offloading should place 36" traffic cones in front of the tanker during offloading. The
cones should be removed by the EM Johnson employee following verification that all
tanker hoses have been properly disconnected from the fill piping and tanker and that
the caps on the fill piping have been returned and all appropriate valves, etc. closed.
The tank truck driver, as a matter of policy, should not be allowed to remove the cones or
leave the area until fuel offloading is completed, hoses are disconnected and the cones
are removed.

0 1.5.5 Facility Drainage
1.5.5.1 Drainage Control Devices
(1) Facility drainage (onshore); (excluding production facilities).
(i) Drainage from diked storage areas should be restrained by valves or other positive
means to prevent a spill or other excessive leakage of oil into the drainage system or
inplant effluent treatment system, except where plan systems are designed to
handle such leakage. Diked areas may be emptied by pumps or ejectors; however,
these should be manually activated and the condition of the accumulation should be
examined before starting to be sure no oil will be discharged into the water.
(ii) Flapper -type drain valves should not be used to drain diked areas. Valves used for
the drainage of diked areas should, as far as practicable, be of manual, open -and -
closed design. When plant drainage drains directly into water courses and not into
wastewater treatment plants, retained storm water should be inspected as provided
in paragraphs (e)(z)(iii) (8), (C) and (D) of this section before drainage.
This section requires that drainage from diked storage areas be restrained by valves or
other positive means to prevent a spill or other excessive leakage of oil into the drainage
system. The concrete secondary containment curb for the hydraulic oil AST is
constructed to restrain a spill.
The spill containment vault is pumped out on an as needed basis by a waste disposal
contractor. The vault has no pump or drain.
1.5.5.2 Management of Storm Water Within Containment Structures / Sumps
Accumulated stormwater within the dike should be inspected prior to release or removal
(see §112.7 (e) (2) (iii) (13)).
(iii) Drainage of rainwater from the diked area into a storm drain or an effluent discharge
that empties into an open water course, lake, or pond, and bypassing the in -plant
treatmentsystem maybe acceptable if -
(A) The bypass valve is normally seated closed.
(8) Inspection of the run-off rain waterensures compliance with applicable waterquality
standards and will not cause a harmful discharge as defined in qo CFR part 11o.
(C) The bypass valve is opened and resealed following drainage under responsible
supervision.
(D) Adequate records are kept ofsuch events.
The above referenced portion of the SPCC regulation requires that storm water
accumulated within a secondary containment structure may be released to a surface
water body without treatment under certain circumstances. Written logs must be
maintained for all water released from the secondary containment structure.
EM Johnson Water Treatment Plant - Raw Water Pumping Station Page 1-15
SPCC Plan

0 1.5.5.3 Recommendation
El
The City of Raleigh should not release stormwater from fuel storage secondary
containment structures without analytical testing to confirm dissolved phase
contaminants in the water. Sheens may be obvious to denote signs of gross quantities
of fuel, however, dissolved fuel constituents can not be distinguished by sight.
Therefore, the City should implement one of the following alternatives to address this
issue:
Contract a waste disposal company to dispose of all water within the
secondary containment structures,
Cover the structures with a canopy to prevent accumulation of stormwater,
Develop a pretreatment system with POTW discharge of the water, or
Implement a water quality testing program for the water in the dikes to
confirm that dissolved phase concentrations are below water quality
standards prior to release to surface waters.
If water is released from the secondary containment structures to surface waters, a
written log must be maintained for each release event.

Page 1-16

0 1.5.6.1 Material Compatibility
(i) Do not use a container for the storage of oil unless its material and construction are
compatible with the material stored and conditions of storage such as pressure and
temperature.
The storage systems previously identified are constructed of materials consistent with
industry recognized practices for storage of No. z fuel oil and hydraulic oil. The UST is
subject to corrosion protection requirements of qo CFR 280.
1.5.6.2 Secondary Containment
(ii) Construct all bulk storage container installations so that you provide a secondary
means of containment for the entire capacity of the single largest container and
sufficient freeboard to contain precipitation. You must ensure that diked areas are
sufficiently impervious to contain discharged oil.....
Generator Building — Secondary Containment Vault
The spill containment vault will store a portion of a potential spill within the generator
building. Although the volume of the vault is approximately 4600 gallons, the storage
capacity may be somewhat less due to the elevation difference between the vault and
the generator building and the level of the pipe entering the vault.
® Hydraulic Oil AST & Reservoir— Inside Pump Station Building
Concrete curbing around the perimeter of the hydraulic oil AST will contain
approximately 151 gallons of hydraulic oil. Approximately 207 gallons of hydraulic oil is
stored in the AST system. A spill exceeding the volume of the curbing may flow out the
door of the generator building and flow overland to the nearest storm water catch basin.
Hydraulic Oil Distribution — Valve Pits
Each valve pit has sufficient secondary containment volume to retain a spill of the entire
contents of the hydraulic oil system. Water or oil is removed from each pit by a manually
controlled pump. Water or oil can be pumped to the spill containment vault or if the
water appears clean, the operator can pump the oil to the Lake.
Tank Truck Offloading
No secondary containment is provided for the tank truck offloading, other than the area
offered by the asphalt paved parking lot, speed bump and curb and gutter. This
containment potential is dependent on the performance of the spill prevention mat that
is placed over the storm water catch basin in the center of the lot.
This area is estimated to have a volume of approximately 600o gallons for a liquid level
height of approximately 3-inches of water (and assuming the mat will retain liquids at
the storm water catch basin).
EM Johnson Water Treatment Plant — Raw Water Pumping Station Page 1-17
SPCC Plan

1.5.6.3 Ancillary AST Devices to Avoid Discharges
(8) Engineer or update each container installation in accordance with good engineering
practice to avoid discharges. You must provide at least one of the following devices:
(i) High liquid level alarms with an audible or visual signal at a constantly attended
operation or surveillance station. In smaller facilities an audible air vent may
suffice.
(ii) High liquid level pump cutoff devices set to stop flow at a predetermined
container content level.
(iii) Direct audible or code signal communication between the container guager and
the pumping station.
(iv) A fast response system for determining the liquid level of each bulk storage
container such as digital computers, telepulse or direction vision gauges. If you
use this alternative, a person must be present to monitorgauges and the overall
filling of bulk storage containers.
(v) You must regularly test liquid level sensing devices to ensure property operation.
The primary fuel transfer operation involves the offloading of No. z fuel oil tank trucks
when filling the 30,000 gallon UST. In this scenario, the tank truck operator uses the
truck mounted pump to transfer fuel from the tank truck to the UST. The UST has a gauge
mounted on the tank which reflects the fuel level within the UST. Therefore, the E.M.
Johnson employee responsible for tanker offloading supervision should be able to
communicate with the driver during offloading to prevent an overfill of the UST system. It
is unknown whether the UST has an overfill prevention device.
1.5.6.4 Recommendation
The gauge on the UST should be tested in accordance with the regulation and
manual tank gauging should be completed to verify the liquid level gauge
reading. The gauge should be repaired or replaced if necessary.
The UST should be equipped with an overfill prevention device to prevent
overfilling of the UST.
A leak detection system should be installed on the UST to detect a loss of
product and the system should be integrated into the EM Johnson Water
Treatment Plant's SCADA system.
EM Johnson Water Treatment Plant - Raw Water Pumping Station
SPCC Plan
Page 1-18

® 1.5.7 Facility Transfer Operations, Pumping & Facility Process
The SPCC regulation requires the following provisions:
Cathodic protection of buried metallic piping;
Capping terminal connection of piping at transfer point and label with origin when
not in service;
Design of pipe supports to minimize abrasion and corrosion and allow for expansion
and contraction;
Regularly inspect all aboveground piping, valves and appurtenanances.
As built drawings reflecting the actual construction of the fuel distribution systems are not
available. Review of site conditions indicates that buried metallic fuel piping is present between
the generator building and the UST. Often corrosion of buried metal piping causes a release of
petroleum product that with time can migrate into storm sewer systems or surface at grade and
flow overland away from the line location.
1.5.7.1 Recommendation
If the metal piping to the generator is directly buried, then it needs to be replaced with
an appropriate pipe material within an outer pipe for secondary containment. Piping
sumps should be placed at the UST and within the generator building so that piping
connections to the UST and fuel manifold can be inspected and a means of leak
detection in the supply and return manifold piping from the generator can be installed.
Installation of flexible fuel piping in a secondary containment pipe will eliminate the
need for corrosion protection of the buried piping.
The piping sumps should be equipped with liquid level sensors that active an alarm
circuit that is integrated into the EM Johnson SCADA system.
Regular inspections of the piping should be incorporated into the SPCC Plan.

0 1.6 INSPECTION & RECORDS
The SPCC regulation requires that periodic inspections of the equipment and facility be completed
for the site.
112.7 (e) Inspections, Tests & Records
Conduct inspections and tests required by this part in accordance with written procedures
that you or the certifying engineer develop for the facility. You must keep these written
procedures and a record of the inspections and tests, signed by the appropriate supervisor
orinspector, with the SPCC Plan fora period of three years. Records of inspections and tests
kept under usual and customary business practices will suffice for purposes of this
paragraph.
1.6.1 Inspections

• Debris / vegetation within the secondary containment system
1.6.2.2 Recommendation
As a matter of frequency of inspections, Withers and Ravenel recommends that an
inspection of the fuel distribution and storage equipment be completed at the time of
each fuel tanker offload and at minimum on a weekly basis. The inspection form should
be completed in the field during the offloading event.
i.6.1.3 Facility Inspection
The facility inspection should include the following items:
• Storm drain network in proximity to the AST system.
Catch basins nearby AST.
Storm drain outfall at Creek.
• Pavement at tanker offloading station.
Ground surface between offloading station and AST.
1.6.2 Tests
The SPCC regulations with respect to testing are as follows:
112.8 O (6) Test each aboveground container for integrity on a regular schedule, and
whenever you make material repairs. The frequency of and type of testing must take into
account container size and design.... You must combine visual inspection with another
testing technique such as hydrostatic testing, acoustic emissions testing, oranother system
of non-destructive shell testing. You must keep comparison records and you must also
inspect the container's supports and foundations. In addition, you must frequently inspect
the outside of the container for signs of deterioration, discharges, or accumulation of oil
inside diked areas....
The previous section discussed periodic visual inspection of the fuel storage and distribution
equipment. The SPCC regulation requires a testing method to supplement the visual
inspections.
2.6.2.1 Recommendation
The UST system should be integrity tested annually.
Pressure testing of all directly buried underground piping should be completed on an
® annual basis. The testing should be completed in accordance with the
manufacturers recommendations for the pipe material.
EM Johnson Water Treatment Plant —Raw Water Pumping Station Page 1-21
SPCC Plan

Records of the tests should be maintained by the City of Raleigh.
All liquid level alarms and control circuitry should be tested monthly.
1.6.3 Records
All inspections and testing should be documented and maintained in a written log for the
facility. The SPCC log will be subject to inspection if the facility is reviewed by the EPA.
1.6.3.i Recommendation
Develop and maintain log of all inspections and tests completed for the facility.
1.7 SPILL RESPONSE PLAN
qo CFR 112.7 (a) (3) requires that the SPCC Plan include the following information:
(iv) Countermeasures for discharge discovery, response and cleanup (both the facility's
capability and those that might be required of contractor);
(v) Methods of disposal of recovered materials in accordance with applicable legal
requirements; and
(vi) Contact list and phone numbers for the facility response coordinator, National
Response Center, cleanup contractors with whom you have an agreement for response,
and all appropriate Federal, State and local agencies who must be contacted in the case
of discharge.
The following paragraphs address each of the above referenced requirements.
EM Johnson Water Treatment Plant -Raw Water Pumping Station Page 1-22
SPCC Plan

0 3.7.3 EM Johnson Water Treatment Plant Staff -Spill Response Qualifications
Evaluation of the fuel handling and storage practices at this facility suggest that spill volumes
may range from relatively small releases associated with leaks and drips from equipment,
piping, etc. to a spill of up to 30,000 gallons of fuel oil due to an equipment malfunction,
product line failure, etc.
OSHA has training requirements for employees involved in emergency response operations.
Training requirements are discussed in Section 1.8 of this report. The City should ensure that all
personnel required to respond to spills of fuel and or water treatment chemicals at the plant are
properly trained in the emergency response procedures.
The magnitude of the spill and level of training of plant personnel will likely dictate whether the
staff of the EM Johnson facility has the ability and resources to contain and cleanup a spill
without jeopardizing the health and safety of the plant personnel. Other City resources such as
the Fire Department, should be called upon to control potential fire and explosion hazards in
conjunction with the response to a spill event.
1.7.1.1 Evaluate Spill Scenario & Hazards Associated With Petroleum Spill Response
The following information appears in the z000 Emergency Response Guidebook,
developed by the US Department of Transportation, concerning approaching a spill and
determining whether entry is appropriate to respond to a spill of flammable liquids
® (which includes No. 2 Fuel Oil / Diesel Fuel). This publication was developed as a
guidebook for first responders during the initial phase of a hazardous materials incident.
Although this publication was developed for trained fireman, hazardous materials
technicians and other emergency personnel involved in spill response, it is offered here
for consideration of the City of Raleigh in determining the hazards created by a
petroleum spill on the property.
SAFETYPRECAUTIONS
APPROACH CAUTIOUSLYFROM UPWIND. Resist the urge to rush in; others cannot be
helped until the situation has been fully assessed.
SECURE THE SCENE. Without entering the immediate hazard area, isolate the area
and assure the safety of people and the environment, keep people away from the
scene and outside the safety perimeter. Allow enough room to move and remove
your own equipment.
IDENTIFY THE HAZARDS. Placards, container labels, shipping documents, material
safety data sheets, Rail Car and Road Trailer Identification Charts, and/or
knowledgeable persons on the scene are valuable information sources. Evaluate all
available information and consult the recommended guide to reduce immediate
risks. Additional information, provided by the shipper or obtained from another
authoritative source, may change some of the emphasis or details found in the
guide. Remember, the guide provides only the most important and worst case
scenario information for the initial response in relation to a family or class of
® dangerous goods. As more material -specific information becomes available, the
response should be tailored to the situation.
EM Johnson Water Treatment Plant -Raw Water Pumping Station Page 1-23
SPCC Plan

ASSESS THESITUATION. Considerthefollowing:
Is there a fire, a spill or a leak?
What are the weather conditions?
What is the terrain like?
Who/what is at risk: people, property or the environment?
What actions should be taken: Is an evacuation necessary?
Is diking necessary? What resources (human and equipment) are required and are
readily a vailable?
What can be done immediately?
OBTAIN HELP. Advise your headquarters to notify responsible agencies and calf for
assistance from qualified personnel.
DECIDE ON SITE ENTRY. Any efforts made to rescue persons, protect property or the
environment must be weighed against the possibility that you could become part of
the problem. Enter the area only when wearing appropriate protective gear (see
PRO TECTI VE CL 0 THING, page364).
RESPOND. Respond in an appropriate manner. Establish a command post and lines
of communication. Rescue casualties where possible and evacuate if necessary.
Maintain control of the site. Continually reassess the situation and modify the
response accordingly. The first duty is to consider the safety of people in the
immediate area, including your own.
ABOVEALL --- Do not walk into or touch spitted material. Avoid inhalation of fumes,
® smoke and vapors, even if no dangerous goods are known to be involved. Do not
assume that gases or vapors are harmless because of tack of a smelt - odorless
gases or vapors may be harmful.
The City of Raleigh Fire Department and cleanup contractors should be contacted to mobilize to the
site to assist with cleanup of large spills. The following information appears in the z000 Emergency

The EM Johnson in-house personnel should be expected to complete the following spill response
and cleanup measures for relatively small spills:
Evaluate the spill scenario and identify hazards.
Identify source of release.
Stop the discharge when personnel safety is not compromised (close valve / shut down
generator, etc.)
Identify path of spill migration
Place sorbent materials to deter now along path of spill migration (storm drains, creek,
asphalt driveway / curb and gutter leading to storm drain).
Outside resources are expected to assist with the following spill response and cleanup measures:
EM Johnson Water Treatment Plant — Raw Water Pumping Station Page 1-26
SPCC Plan

C� J
Fight fires.
Place foam on pools of product (fuel) to prevent fire or explosion.
Recover free phase fuel from the ground, storm drain system and creek.
Excavate petroleum contaminated soils along path of spill.
Containerize and dispose of contaminated booms and sorbent materials.
Mitigate vapors in buildings, storm drains, etc.
Complete other spill mitigation procedures downstream of the facility.
The following paragraphs describe spill response measures outlined for the facility.
1.7.1.2 Identify Source of Release & Stop Discharge
Petroleum spills at the facility are expected to be related to the scenarios listed in the
table on the following page, however, other scenarios may be possible. Examples of
response actions to stop the release should be reviewed and upated with specific
information pertaining to the arrangement of fuel piping and equipment:
Spill Scenario
Response to Stop Release
Blown tanker hose or tank truck
Tank truck operator to shut down tank truck mounted
equipment malfunction during
pump

Failure of fuel supply or return
Shut down valves serving the generator piping and stop
piping serving emergency
generator.
generator.
Plant personnel responsible for maintenance of petroleum equipment and fuel handling
operations should be familiar with valve and piping arrangement for all generator
systems and the boiler system.
1.7.1.3 Identify Path of Spill Migration
Petroleum spills that occur in proximity to the fuel storage area are likely to enter storm
drain catch basins positioned along the asphalt paved driveway. The storm drain
network discharges directly to Falls Lake. The City has recently installed a new outlet
control structure on the two storm drain systems serving the plant. The structures
appear to be constructed to allow a spill to be contained within the storm drain network
by a future slide gate or other device (such as an inflatable plug).
If a spill enters the stream and migrates beyond the outlet structure is located, then the
spill will flow through a set of concrete swales to Falls Lake.
1.7.11.4 Placement of Sorbent Booms / Spill Control Methods
Spill Control Materials
The City should maintain a supply of spill control materials (sorbents, booms, etc.) in
proximity to the generator room. At a minimum, the supplies should include the
® following:
Fire extinguishers
EM Johnson Water Treatment Plant —Raw Water Pumping Station Page 1-27
SPCC Plan

Petroleum sorbent pads and pillows,
Sorbent booms for spills on land (weighted) and water
Temporary flexible dikes / matts to protect catch basins in asphalt
pavement.
Granular absorbent materials
Large trash bags
• 55 Gallon Drums
Personnel protective equipment (Tyveks, boots, gloves, goggles)
Personnel should train in the use of sorbent materials. Recent developments in spill
materials allow for field fabrication of flexible dikes around storm drains, etc.
Diversion Berm Construction
Heavy equipment, such as backhoes, trackhoes, and front end loaders can be used to
excavate diversion ditches, cut off trenches, or import soil for berm construction for
overland spills of fuel (if the need warrants).
2.7.2 Disposal of Petroleum Contaminated Spill Media
Disposal of petroleum contaminated media must be completed in accordance with State and
Federal regulations. The following paragraphs address the anticipated petroleum waste
® streams.
Sorbents
All contaminated spill control media should be recovered and placed in 55-gallon drums or other
approved devices for proper disposal.
Free Phase Product / Contaminated Water
All waste fuel oil and fuel mixed with water, etc. should be reclaimed by a waste disposal
contractor for proper disposal.
Petroleum Contaminated Soils
All petroleum contaminated soil should be placed on 6-mil plastic for temporary storage
pending arrangement of disposal in accordance with NC Division of Water Quality / Waste
Management criteria.

Treatment Plant Superintendent, who will be assisted by selected members of the plant staff.
In the event of a spill the Plant Superintendent or his designee will be responsible for:
•
actuating internal facility alarms or communication systems, where applicable, to
notify facility personnel during normal working hours, in case of fire or accidental
release.
•
determining the cause and/or source of the spill and ensuring that immediate
response actions to stop the leak and control the spill have been, or are being,
initiated,
•
notifying the local Fire Department in the event of a fire or the likelihood of a fire,
explosion or life threatening condition, or if the spill is not being totally contained on
the plant property,
•
exercising all reasonable measures to control and contain the hazard so as to
prevent or minimize hazards to human health or the environment outside the facility,
ensure that there is "no smoking" in the area of the spill,
•
maintain a chronological log of events and communications during the spill incident,
containment, and cleanup. Record times, names, conversations, instructions given
and instructions received, and take photographs of the spill, containment and
cleanup activities.
notify the North Carolina Department of Environment and Natural Resources, Raleigh
Regional Office,
notify the National Response Center,
•
request assistance from a cleanup contractor, if necessary,
•
document all actions and provide reports to government agencies, arrange for a post
incident investigation to determine the cause(s) of the emergency and steps that can
be taken to avoid a recurrence.
•
and update the SPCC Plan as necessary.
i.7.4 Regulatory Notification Procedures
In the event of a fuel spill at the site, the person that discovers the spill will notify the Plant
Superintendent. He will be notified of all oil/fuel spills, regardless of size. A supply of
absorbent materials (booms, sorbent pads and wipes) and several 55-gallon drums should be
maintained at the site for use with small spills. Site personnel should be trained to stop, contain
and clean up small leaks and spills. An outside cleanup contractor should be called to cleanup
large spills and dispose of waste.
Should the need arise, the designated personnel will call local fire, police and regulatory
officials for additional support. The following action list has been developed for contact of the

1.9 SUMMARY OF RECOMMENDATIONS
The following paragraphs summarize recommendations of the SPCC Plan. The recommendations
should be incorporated into the plan and documented for record keeping purposes. The
recommendations are referenced per applicable section of the SPCC Plan.
. Section
Recommendation
Date of Completion
1.5.i.3
The buried fuel piping buried between the UST location
Facility Piping
and the generators in the generator building does not
have secondary containment. The piping should be
replaced with non-metallic piping in a secondary
containment structure.
Liquid level alarms should be integrated into the piping
sumps and the trench drain of the generator building,
the manhole and the spill containment vault.
1.5.1.5
Lighting should be observed in the vicinity of the No. 2
Facility Lighting
fuel oil storage and offloading areas, the emergency
generators and the pump station building. The lighting
should be supplemented if the ground immediately
surrounding these facilities are not clearly illuminated
during the evening hours (i.e. darkness). It is important
that any potential evidence of a release such as the
overland flow of fuel is easily observed by plant
personnel so that any source of a fuel spill can be
identified and corrected.
1.5.2
The above referenced regulation specifies that a
Facility Tank
secondary containment structure be constructed for
Truck Loading /
tanker offloading. The design should incorporate a

Therefore, the City should implement one of the
following alternatives to address this issue:
Contract a waste disposal company to
dispose of all waterwithin the secondary
containment structures,
Cover the structures with a canopy to
prevent accumulation of stormwater,
Develop a pretreatment system with POTW
discharge of the water, or
Implement a water quality testing program
for the water in the dikes to confirm that
dissolved phase concentrations are below
water quality standards prior to release to
surface waters.
If water is released from the secondary containment
structures to surface waters, a written log must be
maintained for each release event.
1.5.6.2
The City should design and install high liquid level
Secondary
alarm systems in each secondary containment
Containment
structure to detect a catastrophic spill that has the
potential to escape secondary containment. All
secondary containment structures and fuel distribution
points (generators) have spill scenarios where
discharge of fuel is a possibility. Tanker offloading
obviously needs secondary containment because of it's
precarious position in proximity to the storm water
catch basin.
The City should proceed with installation of slide gates
for each storm water outfall for the facility. The slide
gates could be closed during tanker offloading or
during response to a spill event.

Reference: AMENDMENT TO SPCC PLAN
E.M. Johnson Water Treatment Plant
Raw Water Pumping Station
Possum Track Road
Raleigh, North Carolina
W&R Project No. 203042.00
Dear Perry:
Withers & Ravenel has prepared this addendum to the Spill Prevention, Control, and
® Countermeasure (SPCC) Plan dated October 2003. This addendum addresses three issues at
the Raw Water Pumping Station not currently addressed in the SPCC Plan:
1. Electrical equipment owned by Progress Energy
2. Hazardous materials and petroleum products brought on -site by contractors.
Electrical Equipment
The City receives electrical commercial power at the Raw Water Pumping Station from
Progress Energy. To serve the various power requirements of the pumping station, Progress
Energy operates and maintains an electrical distribution substation at this location. The
distribution substation provides for the proper electrical voltage at the site.
Withers & Ravenel has spoken with Progress Energy regarding its electrical equipment at
the Raw Water Pumping Station. Based on our conversation with Mr. Mike McDowell, the
equipment in the distribution substation contains oil. As provided in Title 40, Code of
Federal Regulations, Part 112, oil -filled electrical equipment is not defined as a bulk storage,
container. Therefore, the requirements of the Spill Prevention, Control, and
Countermeasures (SPCC) Plan pertaining to bulk storage containers [i.e., §112.8 (c)] do not
apply to the electrical equipment. Progress Energy complies with the remaining SPCC
regulations and prepares an SPCC plan for all of their facilities that meet the aboveground
storage capacity (i.e., greater than 1,320 gallons).
Progress Energy maintains an SPCC Plan for the distribution substation at the Raw Water
® Pumping Station. According to Mr. McDowell, the secondary containment provisions
required by the SPCC Plan are met with the visible gravel dike around the distribution
substation. In the event of a release of oil from the distribution substation, Mr. McDowell

Page 2 of 3
May 5, 2004
® indicated that Progress Energy would respond and take responsibility for the containment
and cleanup of the release.
Based on this information, Withers & Ravenel recommends including no provisions within
the report regarding the electrical equipment owned, operated, and maintained by Progress
Energy.
Contractors' Hazardous Materials and Petroleum Products
Because of the construction projects at the Raw Water Pumping Station, contractors will be
on -site from time to time. As part of the contractor's normal activities, there is the potential
for contractors to use hazardous materials or petroleum products on the site. Depending
upon the magnitude of the construction project, occasions may arise when a contractor
wishes to store materials or products on -site. It is customary and appropriate to address
handling and storing procedures for hazardous materials and petroleum products in the
construction contract documents. Based on our experience, these contract documents
should specify that the contractor is solely responsible for any release of hazardous material
or petroleum product brought on -site by the contractor or in support of the contractor's
operations. However, without reviewing the various documents of other consultants, and
recognizing that not all contract documents contain these procedures, Withers & Ravenel
recommends the following regarding the contractor's handling and storing of hazardous
materials and petroleum products on -site:
1.
The Contractor shall not store hazardous materials or petroleum products upon
the OWNER's property. Hazardous material products are those products that,
when accidentally or otherwise discharged from its primary containment vessel,
qualify as a hazardous waste under 40 CFR Part 261.
2.
The Contractor shall notify the OWNER's representative not less than 24-hours
prior to performing refueling, greasing, or oiling operations to or on contractor
equipment on the Raw Water Pumping Station site.
3.
The Contractor shall prohibit the performance of scheduled periodic maintenance
activities involving the use of any petroleum product on any piece of equipment
while on the Raw Water Pumping Station site.
4.
The Contractor shall provide a means of secondary containment (i.e., absorbent
booms or other suitable containment equipment) when servicing construction
equipment.
5.
The Contractor shall provide a Plan addressing the servicing of construction
equipment while on the Raw Water Pumping Station site. Such plan shall be
submitted in accordance with Section 01300 of the construction contract
documents and prior to bringing any equipment on site. The submittal of the plan
shall provide for not less than 20-working days for the OWNER to review the
plan.
6.
The Contractor shall provide material safety data sheets (MSDS) for all hazardous
material and petroleum products he intends to use on the Raw Water Pumping
Station site during construction.
® Withers & Ravenel will include this amendment in the bound copy of the SPCC Plan. As we

SITE WATER CONTROL NARRATIVE
Background
This report contains the approach and results of a site water analysis conducted for the proposed
temporary concrete plant located off of New Bethel Church Road near the future interchange of Interstate
40 and the future US-70 bypass in Garner, North Carolina. The information in this report is based on
information provided by McCarthy Concrete and Green Engineering who surveyed the site in March
2007. The project encompasses approximately 2.74 total acres and consists of a temporary Central -Mix
Concrete Plant, material stock piles, and site water management devices designed to collect and treat site
water generated by the plants production. The US-70 bypass project is owned by NCDOT and upon
completion will provide relief to the congested US-70 in the Clayton area. The temporary plant
described within this report will provide concrete production for 19,000 CY of concrete during the
construction of a portion of the future US-70 bypass. It is estimated that it will take approximately 15
days for the plant to provide this concrete.
Site Water Management Plan
The most important aspect of the proposed plan is to separate Off -Site Stormwater from On -Site
Wastewater. This is accomplished by placing berms/ditches around the North, West and East Side of the
site. Also Stormwater from the DOT project is kept separate from On -Site Wastewater by not disturbing
the existing ditch system which was approved under the DOH Wake -Johnston Country Project (see
attached plans).
The On -Site water consists of basically two types of wastewater
• High Strength Wastewater as a result of washing trucks and/or the drum from the concrete plant.
Low Strength Wastewater which consists of commingled Stormwater which results from rain
runoff on the concrete plant, trucks, or aggregate piles. Note that the conveyor belts carry rock
and sand not cement.
To provide flexibility on the site all of the water within the site boundary is treated as Wastewater.
However, the proposed plan isolates the High Strength Wastewater from the Low Strength Wastewater to
allow more substantial pre-treatment of High Strength Wastewater prior to release to the final pond.
This separation prevents a small amount of High Strength Wastewater from contaminating a large body
of Low Strength Wastewater.
The portions of the site that carry Low Strength Wastewater flows to a large storage pond, Pond C (see
Drainage Area Map). The Drainage Area Map identifies sub areas "Site-100" that is routed to Pond C.
Wastewater runoff from West area is routed to Pond C by over -land sheet flow and ultimately a Swale.
A trench dam (rocks) has been shown in the Swale to provide further removal of sediments prior to
discharge into Pond C. The East area drains directly to Pond C via over -land sheet flow. This pond also
serves as storage for a 25 year 24 hour storm (see Appendix). A valve has been placed on the outfall
pipe to Pond D. This valve will typically be left in the open position. Refer to Pond D Outfall Pipe
Discussion. However, if there is a problem with the Fortrans treatment unit in Pond D and/or if there is
a large storm this valve can be shut off to provide storage.

Pond A has been designed to provide settling for High Strength Wastewater (largest amount of' solids).
The location of Pond A provides easy access for maintenance or cleaning if required during plant
production. The concrete truck wash down station will be located at Pond A so that contaminates from
the wash down process will drain directly to this pond. This Pond could receive up to 6 CY of concrete
waste per day (see calculations). Therefore separating this pond simplifies maintenance and prevents the
down stream ponds from having the settled particles from being re -suspended every time the pond is
maintained.
Once Pond A becomes full it will slowly release Wastewater into a flatly graded channel draining (Pond
B). The flat channel will provide further settling of solids and will reduce the velocity of the
Wastewater. Baffles have been placed in this channel to increase the detention time and provide laminar
flow. Based on a flow rate from the truck wash area of 4,300 gpd, the secondary settling basin will have
a detention time of approximately 4.5 days. The basin dimensions are approximately 80 feet by 22 feet
top width (10 foot bottom width) at a two foot pool depth. As such, the critical settling velocity is
approximately 0.45 feet per day. The Stokes equation predicts that the settling velocity for a 40 micron
(round) particle is 108.5 feet per day. Suspended sediments are defined as particles larger than 40
microns; therefore it is anticipated that all suspended sediments will be removed in the secondary basin.
Using the critical velocity of 0.45 feet per day, the secondary basin should remove all suspended particles
greater than 2.6 microns according to the Stokes equation. As such, a large portion of the total suspended
solids (particles greater than 1 micron), should be removed prior to entering Pond D. (Refer to the
Appendix for the Drainage Area Map and Calculations). Also refer to Outfall Pipe Discussion in the
following section.
Pond D will utilize a Fortrans pH control system to monitor and treat stormwater and Wastewater prior to
discharge downstream (See Manufacture Information in the Appendix). The outlet pipe from Pond B and
C has been sized to restrict flow into Pond D to below the maximum capacity of the pH control system so
that Pond D will not receive more water than it can effectively treat at any time (75,000 gpd). Therefore,
if the valve is left open during a large storm event Pond C will reach capacity prior to discharging
surcharging Pond D. A valve has been placed on the outlet pipe to allow water test to verify that the TSS
and SS are within the limits of the permit. Note according to the manufacturer who has had many years
of experience with the Fortrans system the TSS levels have never been above 17 ing/L and most are
between 9 mg/l and 17mg/L. Note the permit specifies a maximum of 30 mg/l. Also, according to the
manufacturer SS levels have also not been a problem. However, to assure that the water meets the
permit requirement testing will be done by a Geotechnical/Testing firm that has been certified by the
State of North Carolina. Kimley Horn will also review the testing results and make at least one site visit
to verify that proposed improvements have been installed as per the intent of the plan. Pond C will
discharge to an existing 24" RCP. (Refer to Erosion Control later in this document). The 24" RCP was
installed as part of the DOH Wake -Johnston Country Project (see DOT plans in the Appendix).
The combined treatment of multiple ponds and a pH control system will ensure compliance of final
discharge with permitted effluent limits of Total Suspended Solids (TSS), Settleable Solids (SS) and PH
as required under General PermitNCG140000.

Offsite Stormwater
Existing contours indicate that offsite stormwater runoff is naturally routed through the project site (See
Drainage Area Map). In order to keep this stormwater runoff excluded from onsite stormwater and waste
waster, the proposed system includes a berm/ditch around the west, north and eastern boundary of the
site allowing offsite runoff to bypass the proposed system. Calculations show that the berm/ditch will
contain a 25 year 24 hour storm with a minimum of V of freeboard. Haested Methods (Flow Master)
was used for the berm/ditch calculations which have been provided (See Appendix).
Erosion Control
The proposed system has been design to prevent erosion and sediment displacement due to conveyance
of stormwater and Wastewater runoff. Outlet protection has been provided at Pond C. Erosion and
sediment control for this portion of the US-70 project will be enforced under the original erosion and
sediment control permit obtained by NCDOT for the entire US-70 bypass project. Calculations have
been provided (See Appendix)
Soils
The Wake County soils survey indicates that Appling, Wehadkee and Bibb soils are located onsite.
Hydrologic soil group D was chosen for the purpose of runoff calculations.
Methods
Run off volume estimates, stormwater routing and pond sizing was done using "Pond Pack," a Haestad
Methods computer software program that utilizes TR-55 methods of calculating time of concentration
and SCS methods of generating hydrographs. Stokes -Law was utilized to determine the removal rate of
Total Suspended solids in Wastewater.
Conclusion
Based on the analyses provided herein, the proposed storm and waster water management system is
adequate to address the site water requirements of North Carolina Division of Environment and Natural
Resources.

Volume of Hieh PH Wastewater:
19,000 cy of concrete to place on the project which will require 15 days of production. (3 weeks at 5 days per week)
19,000 cy / 15 days = 1,267 cy per day
There will be about 141 loads per day (1,267 cy / 9 CY truck).
We conservatively assume that every other load will be washed out. It is estimated that it will take between 20-30
gal per washout. Our calculations will conservatively use 30 gal.
Therefore, half of the 141 loads will be washed out with 30 gal of water.
141 loads / 2 x 30 gal = 2,115 gal
We will assume a safety factor of 2 which results in 4,230 gpd (Say 4,300 gpd)
Note: The drum will only be washed out once per day and the amount of generated wastewater is considered
insufficient.
4,300 gpd x 15 day = 64,500 gal
The Storage Capacity of Pond C and D is 360,400 gal
Therefore, unless it rains the treatment ponds will not reach capacity prior to the completion of the project.
Volume from a I" storm into Pond A
Area = 0.11 AC (see Drainage Area Map)
0.11 AC = 4,791 sqft
Assuming one 1" rain in a day
4,792 sqft x 1" = 399 sqft = 2,990 gpd (Since 4,300 gpd is greater it was used to in the Stokes Law calculations).

Solids accumulation from Hieh PH Wastewater:
19,000 cy of concrete to place on the project which will require 15 days of production. (3 weeks at 5 days per week)
19,000 cy / 15 days = 1,267 cy per day
There will be about 141 loads per day (1,267 cy / 9 CY truck).
We conservatively assume that every other load will be washed out. It is estimated that 1 % of the load will be left in
the truck and need to be washed out.
Concrete waste per load = 1 % x 9 cy = 0.09 cy.
Half of the 141 loads will be washed out = 141 loads / 2 = 70.5 loads per day
0.09 cy x 70.5 loads per day = 6.3 cy of concrete per day.
Note: The drum will only be washed out once per day and the amount of solids is considered insufficient.
Due to the large amount of concrete that will be washed out of trucks on a daily basis is why Pond A has
been provided in the design.

4 Actual curve number is less than 30; use CN = 30 for runoff computations.
5 CN's shown were computed for areas with 50%woods and 50%gmss (pasture) cover. Other combinations of conditions may be computed
from the CN's for woods and pasture.
6 Poor., Forest litter, small trees, and brush are destroyed by heavy grazing or regular burning.
Fair: Woods are grazed but not burned, and some forest titter covers the soil.
Cood: Woods are protected from grazing, and litter and brush adequately cover the soil.

G.C. Environmental, Inc., was contracted to provide an cngineci:s review and certification that the
Model 5000-S pH Monitor and Control System manul;toured by Coastal Carolina Supply in
Morehead City, NC, could ellectively provide on a continuous basis, an averai,c pl I range of 0-9 units
on the supernate layer of a stormwater/rinse wader sedimentation hasin lypia.rlly li>und at Rcdi-mix
concrete facilities.
SCOPE OF WORK
During the week orAugust 11, 2003, G.C. 1;nvironmcnial, Inc., wituesscd the operation or the Model
5000-S self-contained pH Monitoringand Control System at it Rell i-mix platit. local ed in Durham, NC.
During the two (2) day test program, measurements were made within the la.cililics Stormwater/rinse
watersedimentation basin for pl-I, temperature and depth (buthsupernatcandSludpc), Duringthefirst
day of testing, the basin was found to be heavily loaded with solids anal adjusunonts were made to the
solids blanket to complete testing the following (lay.
TEST METHODOLOGY
A primary sedimentation basin located at. I Rcdi-mix concret.c pl:ntt located in Durham, NC was
treated utilizing the Model 5000-S pH Monitor and Control system. During the test program, the
basin was, on a semi -continuous basis, being red rinse water font the exterior cleaning or cement
trucks. Measurements for pi I, lemperaturu, supernatc and sludge blankets were made within the
sedimentation basin. Initial pl-f ineasurements showed pl 1 ICVJI 01' a1 leas) 110 units_ The
sedimentation basin was rectangular in shape with concrete wall; and bottom 'I'hc basin ranged in
depth of I" atthc inlet to approximately Y at the deepest point. Sludge measurements within the basin
showed that at least 2/3 of the basins depth was comprised orsludge and the retnainder supernatc.
The Model 5000-S pH Monitor and Control System was sci up al the rectangular sedimentation basin
with the intake and discharge hoses situated at opposite ends or the basin. Both the intake and
discharge lines were set at depths within the supernatc layer ol'thc basin. A clockwise flow pattern
was established once the unit began operation and pl I and temperature rnutsurcments were made at
several locations throughout the supernatc layer oft lie sedimentation basin. Approximately eighteen
(18) pH and temperature measurements were collected with a mean lit I value oh 8.56 and mean
temperature values of3094 "C. The pH system was tell to run essentially on a continuous basis over
a four (4) hour period. An estimated volume exisl.im, within tltc scclimentalion basin was 25, 000
gallons with a little over 8000 gallons consisting of rclalively clear stiperriate. 'file amount of 25%o

Sulfuric acid (H,SO,) used to treat the sedimentation basins supernaic was approximately I8-20
gallons.
MODEL 5000-S PH MONITOR AND ('ONTROI, SYSTEM
The model 5000-S pH Monitor and Control System is comprised ol'a I layward lower Flow II (3/4
hp, 56 GPM) centrifugal pump which delivers raw wcuor to a completely contained pl l sensor
connected to a pH meter equipped with control relays which operate two (2) stenncr (60 GPD) acid
injection pumps. The acid 25% l I,SO,, is injected into the pump disch:rrge line which empties into the
sedimentation basin. Sulfuric acid is delivered to the system by 15 gallon carhuoys located outside of
the fiberglass weatherprool'enclosurc which houses all ol'Ihe albrcnlcntioned equipment. On top of
the enclosed is an alarm light which is tied into the pl-I meter which is activated when pl I levels exceed
8.5 pH units or arc below 6.0 units.
CONCLUSION
1. The Model 5000-S pl-I Monitor and Control System is an cllcctivc Nysterrl for the pl I balancing of
sedimentation basins which arc used to collect stormwater runoll' and rinse water, cotnmonly lound
at Red -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 ranked I'10"1 0.0 inches to 2,0 feet. PH
values alter pH stabilization at the sludge/supernate interface wcrc approximately 12.0 units
4. For this test program, approximately 180 mLJI ofsullates were added to the sedimentation basin as
a result of pH adjustment with 250/. sul1bric acid.
5. The 5000-S pH Monitor and Control System is filly automated and provides a p1 I adjusted waste
water which could effectively be reused within the Rcdi-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 specified 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 neutralization 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
• fittings. Inlet and outlet fittings 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 fittings.
• •1 year warranty on all component parts
® and housing.

PROJECT SUMMARY
A RECYCLE FACILITY HAS BEEN DESIGNED TO CAPTURE THE 25YR-24HR STORM EVENT
PLUS TRUCK WASHING AND DRUM
RINSE -OUT WITHOUT DISCHARGE TO SURFACE WATERS. THIS DESIGN CONSISTS OF ISOLATING THE INDUSTRIAL OPERATIONS
FROM THE NON -INDUSTRIAL AREAS. SURFACE STORMWATER/WASTEWATER IS COLLECTED
VIA CONCRETE SURFACE FLUMES
AND DISCHARGES INTO A SERIES OF CONCRETE CHAMBERS DESIGNED TO SETTLE SEDIMENT
AND PROVIDE STORAGE AS
REQUIRED TO MEET NCDWQ REQUIREMENTS. RECYCLE/PROCESS WATER FROM THE LAST
CHAMBER WILL BE PUMPED
OUT AND RE -USED TO IRRIGATE AND HYDRATE AGGREGATE STORAGE AREAS AND RE -USED IN PROCESSED BATCH
CONCRETE.
