AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A. (2.) CHRONIC TOXICITY MONITORING (QRTRLY)
The permittee shall conduct quarterly chronic toxicity tests using test procedures outlined in
the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February
1998, or subsequent versions.
The effluent concentration defined as treatment two in the procedure document is 23%. The
permit holder shall perform quarterly monitoring using this procedure to establish compliance
with the permit condition. The tests will be performed during the months of January April July
October. Effluent sampling for this testing shall be performed at the NPDES permitted final
effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the
Effluent Discharge Monitoring Form (MR-1) for the month in which it was performed, using the
parameter code TGP3B. Additionally, DWQ Form AT-1 (original) is to be sent to the following
address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Branch
1621 Mail Service Center
Raleigh, N.C. 27699-1621
Test data shall be complete and accurate and include all supporting chemical/physical
measurements performed in association with the toxicity tests, as well as all dose/response
data. Total residual chlorine of the effluent toxicity sample must be measured and reported if
chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity
monitoring is required, the permittee will complete the information located at the top of the
aquatic toxicity (AT) test form indicating the facility name, permit number, pipe number,
county, and the month/year of the report with the notation of "No Flow" in the comment area of
the form. The report shall be submitted to the Environmental Sciences Branch at the address

Class C: Waters protected for secondary recreation, fishing, wildlife, fish
and aquatic life propagation and survival, agriculture and other uses
suitable for Class C. Secondary recreation includes wading, boating, and
other uses involving human body contact with water where such activities
take place in an infrequent, unorganized, or incidental manner. There are no
restrictions on watershed development or types of discharges.
Part 11 - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
1. a. Volume of Wastewater to be permitted:
1.5 MGD (Ultimate Design Capacity)
b. What is the current permitted capacity of the Waste Water Treatment facility?
The facility is not currently permitted.
C. Actual treatment capacity of the current facility (current design capacity)?
The treatment of surface water generates a residual sludge as well as a
decant. The normal discharge from a conventional treatment facility is 5%
to 8% of the total flow treated. The maximum decant that can be anticipated
would be 10% of the total flow of the treatment plant. The water treatment
plant capacity designed is 12 MGD that can be expanded to 18 MGD. The
application for the NPDES discharge permit is based upon an 18 MGD
capacity. The total decant requested is 1.5 MGD.
d. Date(s) of construction activities allowed by previous A/C's issued in the previous
two years. N/A
e. Please provide a description of existing or substantially constructed wastewater
treatment facilities;
No existing facilities are to be utilized as a part of this design.
f. Please provide a description of proposed wastewater treatment facilities.
See attached process diagrams.
The treatment process for the residuals of the water treatment plant
include: Backwash Equalization (Dual Media and OF Membranes and
Decant from Thickening Process), Sludge Thickening — Clarifier Type 3%
Solids, Sludge Thickening Centrifuge —12% Solids, Sludge Storage, and
Decant Treatment or Discharge.
The decant flow from the equalization lagoon is proposed to be discharged
into the newly constructed Randleman Lake. The decant flow will be

metered prior to discharge. The meter shall consist of the construction of a
parshall flume and the installation will include an automatic sampler.
g. Possible toxic impacts to surface waters:
Residual Chlorine and the accumulation of Aluminum in the lake over time.
The toxic substances evaluation in the Final Environmental Impact
Statement: Randleman Lake, December 2000, US Army Corps of Engineers,
Wilmington District discussed four potential sources of toxic substances
which have raised concerns about the water quality of Randleman Lake.
These include the abandoned Seaboard Chemical Corporation site, the
closed High Point landfill, the Randleman town dump, and the High Point
Eastside WWTP. As a result of the water intake from Randleman Lake, the
water treatment plant may have the potential to concentrate toxic
substances from these sources within water treatment residuals.
h. Pretreatment Program (POTWs only): N/A

4. Alternative Analysis Evaluation: Has the facility evaluated all of the non -discharge
options available. Please provide regional perspective for each option evaluated.
Spray Irrigation:
Re -use with the method of spray irrigation would be limited due to the remote
location as well as the volume. The highest application rate for a constructed golf
course anticipated would be 1Yh inches per acre per week. At this application rate,
the acreage would be 514 with a full replacement area. The average golf course
irrigates approximately 150 acres. This flow rate would require three or more golf
courses to participate. Ownership issues involved with re -use areas such as golf
courses has restricted this option because the application could at anytime be
denied by the owner.
Connection to Regional Sewer System:
The Randleman Lake WTP will not be within a 5-mile distance of any wastewater
treatment facility. The closest facility is Randleman Wastewater Treatment Plant,
which is a 1.7 MGD facility. There are also no wastewater treatment facilities
planned as a part of the facility. The facility will include a septic tank for handling
domestic waste generated by the operators. There are no plans to construct a
sewage system within a 5-mile radius in the next five years.
Subsurface:
The option of land based discharge is severely limited by the adjacent soils
properties and the lack of available land. The Randleman Rule, which protects the
water quality in the lake and water basin, requires that a 200-foot buffer be
provided from the lake perimeter and a 100-foot buffer from all seasonal streams.
NPDES Permit Staff Report
Version 10/92
Page 5

The rule limits land availability for development of the water treatment plant
facility, and subsequently be provided for any land application systems on site.
The cost for property and the cost of the equipment for land application, coupled
with the required maintenance of the system make it unfeasible.
Other disposal options:
Recycle of the decant by return to the front-end (flash mix) of the water treatment
plant was considered as an option. This practice is strongly discouraged by the
Water Supply branch of DENR.
5. Other Special Items:
PART IV - EVALUATION AND RECOMMENDATIONS
The Winston-Salem Regional Office recommends approval of the Randleman Lake
Water Treatment Plant permit for discharge as described in the submitted plans.

The Piedmont Triad Regional Water Authority is requesting a new NPDES permit for the
discharge of the decant from a proposed WTP. The WTP plant is a 12 MGD facility with
potential to expand to 18 MGD. The source water for the WTP will be Randleman Lake. Maps
submitted by the applicant indicate that the water intake for the WTP will be downstream of the
High Point Eastside WWTP. In letter dated 2/5/2003, DEH-Public Water Supply states that
they do not object to the discharge of water plant wastewater, properly treated, back into
the reservoir, for maximum dilution, below the raw water intake. A Finding of No
Significant Impact (FONSI) was issued on March 18, 2003 and signed by Linda Sewall,
Director of Division of Environmental Health.
From the 2000 Catawba River Basinwide Management Plan:
In November 1998, waters in the proposed Randleman Reservoir watershed were reclassified to
WS-IV CA.. Rules have been adopted (15A NCAC 2B 0.0248 through 0. 0251 io help prevent
potential water quality problems in the proposed reservoir. The rules address point source
discharges by not allowing new or expanding discharges into the watershed except for High
Point Eastside WWTP. This facility will have to meet phosphorus limits established to protect
Neater quality standards. The rides also aekb•ess nonpoint source pollution in the Randleman
Reservoir watershed with management strategies that maintain and protect riparian areas and
require urban stormwater programs to be developed by local governments and land use authority
in the watershed.
Local governments are required to develop ordinances or modify existing water supply
ordinances to protect riparian areas and implement stormwater management plans by January 1
2000.
The waste generated will include sludge removal from the clarifier, backwash of the dual media
filters, and backwash from the membrane filters. The waste generated from these three is
normally <8% of the total flow entering the plant or 1.5 MGD for a 18 MGD facility. *** Note
8% of 18 MGD is 1.44 MGD, 8% of 12 MGD is 0.960 MGD. The requested flow for the waste
portion is based on the expansion flow of 18 MGD, not the initial flow of 12 MGD. Need to
verify that this amount of flow is needed. (Consultation with DAG, since FONSI has been

Additives in the water process
• Potassium Permangamate
• Alum — 2002 EA indicates that most of the phosphorus present in the raw water will be
removed as a precipitate with the coagulation solids. 30 —50 mg/I of alum will be added.
This is sufficient to remove 2.7 — 4.7 mg/I of phosphorus. Predicted TP concentration is 0.06

mg/l. "Actual June 2002 data from the Randleman Lake Reservoir shows Total
Phosphate is 3.1 mg/l. This is 50X greater than the predicted TP level.
• pH adjustment,
• Polymer,
• Chlorine,
• DeChlorination,
After the granular activated carbon contactor,
• Chlorine
• Fluoride,
• pH adjustment,
• corrosion inhibitor (February 2002 Environmental Assessment indicates that the corrosion
inhibitor will be a phosphate compound, zinc orthophosphate. Will be added downstream of
where filtered water will be removed for filter backwashing.
• NH3.
Backwash from the Ultrafiltration Membrane and sludge blowdown from the clarifier will go to
the backwash EQ basin and sludge thickener for discharge back into Randleman Lake.
The source water from the Deep River has been sampled (6/12/2002) and contains the following
substances:
Total Hardness --------- ---------------- 19 mg/l
Sulfate ------------------------------------- 44 mg/l
Chloride --------------------------------- 5.5 mg/l
Calcium ----------------------------------- 13 mg/1
Magnesium -------------------------------- 5 mg/1
Sodium ---------------------------------- 34 mg/1
Aluminum ---------------------------- 0.089 mg/l
Iron------------------------------------ 0.137 mg/1
Manganese------------------------------<0.010 mg/l (filtered)
0.035 mg/1(unfiltered)
Barium -------------------------------- 0.017 mg/1
Fluoride ------------------------------- 0.500 mg/l
Total Dissolved Solids -------------- --204 mg/1
Comments from Group EAA review:
-Contact Customer Service Center — see if they have a FONSI
-get predicted effluent data. There should be rough estimates of the predicted effluent. Removal
efficiencies are available.
-Process flow diagram in the EAA does not show the wastewater discharge. What component is
being discharged? Where does decant go?
-Be sure to include chlorine limit in the permit.

Contacted the project engineer with additional info request for predicted effluent data, revised
process flow diagram that showed discharge location, and copy of FONSI. On October 17, 2003,
received from engineer:
• The Finding of No Significant Impact (FONSI) was issued on March 18, 2003 and signed by
Linda Sewall, Director of Environmental Health.
• Predicted effluent data
Sample from SC Public Service/Moncks Corner, SC
pH 6-9 SU
TSS 2.0 mg/I (mo. avg) 2.0 mg/I (da. max.)
Aluminum 0.240 mg/I
TRC 0.040 mg/I
Total P <0.05 mg/I
Not sure how representative this is to the water quality of a North Carolina water body. Engineer
needs to do predicted removal efficiencies for this WTP
• Process flow diagram showed that decant from the sludge thickener goes to the equalization
basin then to the meter and is then discharged into Randleman Lake. Decant from the
centrifuge also goes to the meter and is discharged.
Recommended Effluent Limits/Monitoring
• 2/month effluent monitoring for: Aluminum, Calcium, Copper, Iron, Magnesium,
Manganese, Zinc (if added before filter backwashing), TSS, Fluoride (if added before
filter backwashing) Zn and FI were not included in monitoring because both were
added after the filter backwashing.
• Added limits/monitoring for settleable solids, turbidity, and TSS. Per 15A NCAC 2B
.0508, these parameters are minimum requirements for Water Supply Plants. EA
submitted by facility anticipated that limits for settleable solids and TSS would be given
based on limits for other WTPs.
• Quarterly monitoring for Total P and Total N (TN monitoring per recommendation of
SAW since discharge will be into a lake. Source water from Randleman Lake Reservoir
contains nitrate nitrogen. )
• Limits for TRC = 28 ug/l , pH = 6-9 SU , Whole effluent toxicity monitoring @ 23%,
Flow = 1.5 MGD

I appreciated the opportunity to discuss the permit application with you this morning.
During that conversation, you requested three items regarding the permit application.
These included a Finding of No Significant Impact (FONSI) on the Environmental
Assessment for the water treatment plant, results from similar decant discharges at other
water treatment plants, and an updated process flow diagram.
We have enclosed with this letter, copies of all three items. The decant sample is from a
similarly designed facility utilizing coagulation, upf low clarification, and granular filters.
If we can provide any additional information to assist you in your review of this project,
please contact this office.

FINDING OF NO SIGMFICANT IMPACT (FONSII
Piedmont Triad Regional Water Supply
Randleman Water Treatment Plant
Randolph, North Carolina
The State Environmental Policy Act (G.S. 113A-1 through 10) requires that the
Division of Environmental Health determine whether a proposed major agency action will
significantly affect the environment. The Piedmont Triad Regional Water Supply Randleman
Water Treatment Plant project is such a major action.
In order to determine whether construction of the proposed water treatment plant,
water intake, and pumping station will cause significant environmental impacts, an
environment assessment has been prepared. This environmental assessment is attached. It
contains detailed information on the key issues, including. a brief description of the proposed
project and a summary of probable environmental impacts. None of the impacts were found
to be significant.
On the basis of the analysis of the impacts as shown in the environmental assessment,
no Environmental Impact Statement (EIS) will be prepared. This FONSI completes the
environmental review record, which is available for inspection at the State Clearinghouse.
Summary of FONSI for publication in the Environmental Bulletin: After completion
of an environmental assessment under G.S. 113A-10, a FONSI has been made in the case of
the proposed project. Information supporting the need for the proposed project was
reviewed, along with relative impacts, other alternative approaches and mitigating measures.

GENERAL INFORMATION
• Randleman Lake Water Treatment Plant
• Guilford County
• 2216 West Meadowview Road, Suite 204, Greensboro, NC 27407 PH: 336-547.8437

B. The facility requiring a discharge is a surface water treatment plant that will be operated by
the Piedmont Triad Regional Water Authority. The plant will be constructed adjacent to the
newly constructed Randleman Lake and will have an initial capacity of 12 MGD with
expansion capabilities up to 18 MGD. The maximum discharge from the facility will be
approximately 8% of the daily flow or approximately 1.5 MGD.
1. Capacity of Plant: The capacity of the Piedmont Triad Regional Water Authority Water
Treatment Plant is based on the needs of the participants.
The waste generated by a L MGD plant includes sludge removal from the clarifier,,
backwash of the dual media filters, and backwash from the membrane filters. The sludge
blowdown rate in the clarifier is dependent upon raw water quality being treated;
however, the maximum discharge is less than 30/6 of incoming flow. The volume of
discharge from backwashing the dual media filter is based upon the settled water quality
(quality of water from the sedimentation process) and time. The anticipated filter run
time is 60 hours but according to operational requirements, the run time should not
exceed 100 hours. Similarly, the membrane backwash rate will be based on the water
,. quality from the dual media filters which will be high. The efficiency of the membranes is
estimated to be 950/6 with only 5% waste flow.
The total of these three is normally less than 8% of total flow entering the plant or 1.5
�o MGD for an 18 MGD facility. The waste stream calculation sheet is attached.

The waste stream generated; by the operation of the facility will be minimized in order to
provide the highest efficiency of operation and the greatest return from the water treatment
facility., An analysis of flow restricting or low flow devices is not applicable to the discussion
of the water treatment plant.
.. The waste flow from the clarification unit is separated from the waste flow from the
backwash operations of the filters due to the amount of solids contained in the waste
_ product. The sludge blowdown from the clarification units will go directly to a sludge
thickener, which is a round clarifier type thickener with a loading of 400 gpd/sq. ft. The
decant from this flow will be directed into an equalization lagoon. The equalization lagoon is
a 1.5 million gallon concrete tank that will be utilized to stabilize the backwash flow from the
granular filters and accept the flow from the membrane filtration. The size and baffling of the
tank allows any suspended solid particles to settle prior to decanting from the top of the tank.
The flow will be metered through a parshall flume prior to discharge.
C. There are no existing treatment facilities to be utilized as a part of this design.
D. The water treatment plant is presently planned for capacity of 12 MGD expandable to 18
MGD. The site on which the water treatment plant will be constructed has the ability to be
expanded to a larger capacity in the future. The waste stream generated by the increased
treatment facility would be increased.

3. Decant Treatment or Discharee: A block diagram is attached. The original design
included filtration and recycle. The Owner is now requesting a decant permit which will
require the installation of a flow meter and sampling station with a decant permit. The
decant water from the equalization lagoon would be discharged to Randleman Lake. The
total suspended solids would be less than 20 mg/1.
F. WATER SUPPLY AND SOURCE WATER DATA
The source water will be the Deep River impounded by Randleman Lake. Final water quality
of the lake cannot be determined at this time. A water sample has been analyzed of the Deep
River and is attached.

SECTION II
EVALUATE DISPOSAL ALTERNATIVES
GENERAL
The sludge handling facilities for the water treatment plant include equalization lagoon, clarifier
thickener, and centrifuge dewatering. This equipment will remain in place for all of the alternatives.
The additional requirements for each will be included with the description.
The Present Value Analysis that is attached were calculated using a 20-year evaluation period. The
estimated discount rate that is being used by the Owner in their evaluation of this project is 50/6.
A. CONNECTING TO A SEWER COLLECTION SYSTEM
1. F-xisthng Sewerage System The water treatment plant is being constructed on the
perimeter of the newly constructed Randleman Lake. The facility will not be within a 5-
mile distance of any wastewater treatment facility. The closest facility is Randleman
Wastewater Treatment Plant, which is a 1.7 MGD facility. There are also no wastewater
treatment facilities planned as a part of the facility. The facility will include a septic tanka
for handling domestic waste generated by the anticipated nine operators that will be on
site. A map has been attached to show the location of the facility.
A Present Value Analysis was not performed for this alternative since there is not a
facility within a reasonable distance that can be utilized. There is also no potential users
within this region at this time that would be able to share in the cost of the facility.
2. Planned Sewerage System: There is no planned sewerage system within a 5-mile radius
that will be constructed within the next five years.
B. LAND BASED DISPOSAL
1. Available and Suitable Land for a Subsurface System:
The water treatment plant is being constructed on the perimeter of the newly
constructed Randleman Lake. The Randleman Rule, which protects the water quality in
the lake, requires that a 200-foot buffer be provided from the lake perimeter and a 100-

Randleman Lake Water Treatment Plant Revised July 2003
Waste Stream Discharge
Engineering Alternative Analysis
foot buffer from all seasonal streams. This severely restricts the land available for the
�► development of the water treatment plant facility, and subsequently be provided for any
land application systems on site.
The treatment plant site is located in Randolph County Soils information provided as a
part of the EA performed for the cons c_tion of cility describes the soils as follows:
The Randleman Lake project area encompasses two major soil associations: (1) Helena -
Wilkes and (2) Georgeville-Tirzah. The Helena -Wilkes soil association is derived
primarily from acid crystalline rocks or mixtures with basic crystalline rocks and is
characterized by yellow, brown, or yellowish -brown firm sandy clay to clay subsoils,
often less than 18 inches thick and seldom more than 35 inches thick, and by a gray loam
FM sand to yellowish -gray sand clay loam surface soil. Generally, the slopes range from 5 to
18 percent, resulting in medium to rapid surface runoff. Internal drainage is slow due to
firm subsoil and shallow parent rock. Most of the soil association is subject to severe
erosion because of the predominance of coarse surface particles and the firm, fine textured
subsoils.
The Georgeville-Tirzah soil association is derived primarily from the Carolina Slate Belt
rocks and is characterized by light red to dark red firm silty clay subsoils and gray -brown
to red moderately firm silt loam to silty clay loam surface soils. Generally, the slopes
range from 4 to 18 percent, resulting in medium to rapid runoff. Internal drainage is
medium. The surface has suffered moderate to severe erosion.
Soils types at the proposed treatment plant site consist of Georgeville, Wynott-Enon and
Wynott-Wilkes-Poindexter soils. The Georgeville soils are comprised of silty clay loam,
with 2 to 15 percent slopes, and are gently sloping, very deep, well drained, eroded soils
on uplands. They have a loamy surface layer and clayey subsoil. Permeability is moderate
and shrink swell potential is low. Seasonal high water table is below 6 feet. The Wynott-
�, Enon soils consist of gently sloping to strongly sloping Zion and Enon soils on uplands.
Zion and Enon soils are moderately deep to very deep and well drained and have a loamy
FJO surface layer and clayey subsoil. Permeability is moderately slow to slow and shrink

Engineering Alternative Analysis
swell potential is high. Seasonal high water table is below 6 feet. The Wynott-Wylkes-
Poindexter soils consist of gently sloping Wilkes, Zion and Poindexter soils on uplands.
Wilkes, Zion and Poindexter soils are shallow to moderately deep and well drained and
have a loamy surface layer and loamy to clayey subsoil. Permeability is moderately slow
to moderate. Shrink -swell potential is moderate for Wilkes soils, high for Zion soils and
low for Poindexter soils. Seasonal high water table is below 6 feet.
Soil borings were performed on the site, specifically for the structural analysis. However,
the soil borings provide an indication of the available soil types with regard to utilization
for land application of the waste stream. All of the soil borings indicate a thin layer (1-2
feet) of organic material over 3-8 feet of soils classified as MH. These are typically soils
not well suited for land application of wastewater.
A calculation of the land required for application was performed, based on a .5-inch/per
acre/per week application rate.
1,500,000 gpd x 7 days=10,500,000 gpw
.5 in/ac/wk =12 in/ft x 43,560 sf/ac x 7.49 g/ft'=13,594 gpw/ac
10,500,000 gpw=13,594 gpw/ac = 772 ac
_ A waste flow of 1.5 MGD would require 772 acres of land application area. With a
requirement for 100% reserve area, the required acreage would be 1,544 acres.
Land disposal of the decant will require that the flow be transferred to a site and then
land applied The additional equipment required will be a pump station located on the
outlet of the equalization lagoon, a force main with a capacity for 1.5 MGD to the
application area, the land application system, and controls. The capital costs are involved
in this alternative will also include purchase of the land and the preparation of the site for
land application.
A Present Value Analysis was performed for this alternative taking into consideration
that land would be purchased on adjacent properties not owned by the Piedmont Triad
I 111 Page 6 Hobbs, Upchurch &z Associates, PA

Engineering Alternative Analysis
Regional Water Authority. The original water treatment plant site was purchased at a
cost of approximately $2,000 per acre. Land that is presently being purchased for the
project costs between $3,500 - $4,000 per acre. The cost assumed for this evaluation is
$3,000 per acre. The Present Value Analysis for this option is $6.432 million.
C. WASTEWATER RE -USE (RECYCLE)
Re -Use Alternative: Re -use options for the wastewater at this site is limited due to the
remote location as well as the volume. Using similar calculations as discussed previously, the
highest application rate for a constructed golf course anticipated would be 1 Ih inches per acre
per week. Using that rate, the acreage required would be 514 acres with a full replacement
area. The average golf course irrigates approximately 150 acres. This flow would require
three or more courses to participate.
DWQ is also concerned about ownership issues with re -use areas. The control of the land
required for golf course application is an issue that has restricted many of the land use
opportunities in North Carolina. Golf courses demand control of the effluent and without
joint ownership could deny the application of the decant on the golf course.
7
Decant could be used in the irrigation system on `site but the total daily volume would not
exceed 5,000 gpd.
Should this area develop in the future, re -use could be reconsidered.
Recycle was considered as an option. The decant from the facility can be returned to the
front-end (flash mix) of the water treatment plant. This practice is strongly discouraged by
.. the Water Supply branch of DENR. A letter is attached from Mr. Wayne Mundun, P.E.,
Head, Technical Services Branch, Public Water Supply Section of DENR, stating their
position on the recycling of decant water.
In order to provide treatment for the decant water to reduce the particulate and organic
levels, an ultrafiltration membrane treatment facility has been evaluated. A Present Value
Analysis was performed and is attached. The system will use ultrafiltration membranes for

removal of particulate matter an cteria. a system will also have the ability to use alum
for coagulation to remove TOC that would be returned and concentrated over a period of
time. The organics would be removed as sludge and wasted in a landfill. The Present Value
Analysis for this option is $2.966 million.
_ D. SURFACE WATER DISCHARGE
The decant flow from the equalization lagoon is proposed to be discharged into the newly
constructed Randleman Lake. The Randleman Lake is located on the Deep River and is
classified as being a flowing stream with a 7Q10 of 7.7 cfs. Attached to this document is
information from the EIS regarding stream flow. The decant from the water treatment plant
discharged from the equalization lagoon will be metered prior to discharge. The meter shall
consist of the construction of a parshall flume and the installation will include an automatic
sampler. The Present Value Analysis for this option is $209,513.
.� E. DISPOSAL COMBINATIONS
A combination of disposal options is not feasible due to the cost for the equipment (and land)
required to make each option operational. In either case, the equipment (and land) must be
properly sized for the system and must be maintained for operation at all times, including
maintenance of the land application area.

SECTION III
FINAL COMMENTS
There are three options available for disposing of the decant (wastewater) generated by the Piedmont
Triad Water Treatment Plant on Randleman Lake:
• Land Based Discharge
• Water Re -use (Recycle)
• Surface Water Discharge
The option of land based discharge is severely limited by the soils adjacent properties and the lack of
available land. The cost for property and the cost of the equipment for land application, coupled with
the required maintenance of the system make it unfeasible.
The two options being considered at this time include recycle of the waste product and surface water
discharge. DENR Plan Review Branch has a requirement that any recycle be limited to 1011/0, but
recycle in any amount is strongly discouraged by DENR. It is for this reason that the surface water
discharge is requested.
The option of recycle has been studied closely by Piedmont Triad Regional Water Authority and
HUA. The proposed treatment proposed includes the installation of membrane filtration with the
option of coagulation of organics to reduce the amount of organics being returned to the water
treatment system. The Present Value Analysis for this option is $2.966 million. One concern with
this option is the position of the water supply section of DENR feels strongly that decant water
should not be recycled to the head of a water treatment plant. A copy of a letter from Mr. Wayne
Munden, P.E., is attached for your review.
The option surface water discharge will not present an environmental concern to the waters of
Randleman Lake. The discharge will eliminate the potential for increasing the organics load to the
water treatment plant, as requested by DENR.

areas within the County in need of wastewater treatment facilities and to explore feasible alternatives.
There are no specific plans to provide additional wastewater treatment plants to serve Randolph
County. Any new treatment facilities will be evaluated and modeled by the NCDWQ in accordance with
basinwide modeling conducted for the Cape Fear River Basin after an NPDES permit application is
submitted for the proposed discharge. An environmental assessment will also be prepared for any new
NPDES discharges to ensure that the most acceptable alternative has been selected and that
environmental impacts have been fully evaluated.
5.3.5.3 Reservoir Yield and Downstream Flow Analyses. In 1990, the PTRWA contracted for an analysis
of reservoir yield and downstream flow for Randleman Lake (Black & Veatch, 1990). The purpose of the yield
analysis was to estimate the safe yield of Randleman Lake considering historic hydrologic conditions, WWTP
return flows, future water demands by High Point from its two reservoirs located in the Randleman Lake
watershed, and the three -tiered operating rule recommended by the NCDWR to assure minimum flows
downstream from Randleman Lake. The purpose of the downstream flow analysis was to calculate the
distribution of flows in the Deep River, downstream from Randleman Lake, both with and without the reservoir
.. project (Appendix A).
The yield of Randleman Lake was calculated to be at least 48 mgd. The two upstream reservoirs, Oak Hollow
" Lake and High Point Lake, have a combined yield of approximately 18 mgd. The yield of Randleman Lake
assumes that 12 mgd of wastewater associated with the yields of Oak Hollow and High Point lakes is
discharged into Randleman Lake by way of the High Point Eastside WWTP and, contributes to the ultimate
Randleman Lake yield. It is estimated that up to.17.5 mgd of the Randleman Lake yield would return to the
Deep River watershed. Of this amount, up to 11.5 mgd would be discharged to the reservoir, while 6 mgd
would be discharged to other areas of the Deep River watershed.
On an average annual basis, flows in the Deep River with Randleman Lake would be less than flows in the
river without the reservoir (Table 24). The difference is approximately equal to the interbasin transfer amounts.
Since the flow reductions reflect the rate of water withdrawals from Randleman Lake, they would be low
initially but would increase overtime. The percent reduction inflow would be greatest at Randleman directly
downstream of the dam and would decline downstream. By the year 2050, Randleman would experience an
estimated reduction in average flow of 27 percent, while Moncure, located 88 miles downstream, would
experience a reduction of about 3 percent.
The presence of Randleman Lake would also alter the downstream flow regime of the Deep River by
moderating high flow conditions and augmenting low flow conditions below the dam. Watercourses in the
.. Piedmont are subject to rapid fluctuations in response to storm events. These may be either minor, short-term
rises in water level after summer storms, or prolonged flooding due to major rainfall events with long return
intervals. Water levels are normally highest during the winter and early spring, and lowest in the late summer
oil and fall. By holding back water during high flow conditions, Randleman dam would tend to reduce the natural
variation of water levels.
Conversely, during low flow periods, flows in the Deep River downstream from Randleman Lake would be
higher with the reservoir than without it. The existing 7-day, 10-year low flow (7Q10) at the Randleman gage
on the Deep River is 7.7 cis. The tiered release program for Randleman Lake would result in minimum low
flow releases of 30 cfs except aurinc drought periods, when lower releases would be allowed. When water in
5-12

the reservoir drops to 60 percent full, 20 cis would be released. When the reservoir is depleted to 30 percent
full, then 10 cis would be released. According to the Dam Safety rules (15A NCAC 2K.0502(c)(6)), when
the usable water supply storage has been reduced to the level which triggers the first reduction in the
minimum flow release (from 30 to 20 cis for Randleman Lake), the average daily water withdrawal must
be reduced by at least 10 percent compared to the average daily withdrawal for the 60-day period
immediately prior to the first reduction in minimum flow. The water supply operator must accomplish
this reduction in withdrawal within two weeks of the reduction in the minimum flow release. When the
usable water supply storage has been reduced to the level which triggers the second reduction in the
minimum flow release (from 20 to 10 cfs for Randleman Lake), the average daily withdrawal must be
reduced by at least 20 percent. Randleman Lake is expected to operate at a volume above 60 percent of its
capacity approximately 90 percent of the time over the long term.
5.3.5.4 Toxic Substances Evaluation. Four potential sources of toxic substances have raised concerns
about the water quality of Randleman Lake. These include the abandoned Seaboard Chemical Corporation
site, the closed High Point landfill, the Randleman town dump, and the High Point Eastside WWTP.
Seaboard Chemical Corporation Site and High Point Landfill. The Seaboard Chemical Corporation site and
the High Point landfill, both located along the Deep River adjacent to the proposed lake site, have been
identified as sources of toxic substances which have contaminated the groundwater at each site. The results
of previous evaluations conducted on the potential effects of these two sites on the water quality in the
proposed lake were presented in the DEIS. Comments on the DEIS were received and indicated that
additional issues related to potential contamination from these sites needed to be evaluated. In order
to further evaluate potential water quality impacts from these sites two additional evaluations were
conducted. The first evaluation was conducted prior to the time when the data from the second set of
studies were available and consisted of a screening analysis conducted by Tetra Tech, Inc. to assess
whether the maximum reasonable loading rate from these sites would potentially result in violations of
water quality standards in the proposed reservoir (Hazen and Sawyer, 1998). This approach was
applied to the ten organic solvent priority pollutants which have been detected in groundwater at the
site, and is expected to overestimate the likely concentrations which will occur in the lake. If these
very conservative screening estimates can be shown to still be below relevant water quality standards,
it can be concluded that contaminated groundwater from the sites will not result in exceedances of
water quality standards in the proposed lake. The screening analysis predicted maximum pollutant
_ concentrations at two sites, one below the source of the pollutants and one at the proposed water
intake. The results of this analysis are summarized in Appendix F. For both locations, the maximum
screening concentration was well below the applicable standard or criterion for each pollutant. Based
on the screening analysis, no exceedances of water quality standards associated with groundwater
loading from the Seaboard Chemical Corporation and High Point Landfill sites are expected.
The second set of evaluations was conducted by consultants for Seaboard Group II and the City of
High Point and consisted of Remedial Investigation (RI) studies for the two sites. Results and
conclusions of these studies were presented in four separate reports. The first report discussed
.. groundwater flow and transport model studies that measured the rates and direction of contaminant
migration (Synesis Environmental, 1999). The second Remedial Investigation (RI) report examined
remediation options, including natural attenuation, hydraulic containment by groundwater pumping, in -
situ treatment by air sparging, and expanded groundwater recovery and treatment (Blasland,1999). The
third report examined the impacts of the site on human health and site ecology (Environmental

The Triad WTP (Greensboro/ High Point/ Winston Salem) in North Carolina is interested
` in optimizing treatment of the Randleman Dam Reservoir in the Superpulsator® Clarifier
and Greenleaf granular filter. This determination will aid in the site's plans to establish
membrane filtration design criteria. The treatment objective of this study is clarification
and total organic carbon (TOC) removal by 45% to comply with the
Disinfectant/Disinfection By -Product Rule. The chemicals utilized for the study were
ferric sulfate and ferric chloride with flocculant aid. A routine analysis and treatability
study were performed on the water source to determine the optimum treatment
chemistry.
PM
Routine Analysis
This surface water sample had a pH of 7.44 with a turbidity of 2.00 NTU and Whatman

Re: Randleman Lake
Water Treatment Plant
r
Dear Mr. Kime:
With reference to our previous meetings, most recent being January 27, 2003, the following is provided:
• It is Public Water Supply's (PWS) understanding that the dam for the Randleman Reservoir is now
complete. The lake water queliry for the initial years of impoundment are of lesser quatiry than the
water from a "seasoned" lake. Therefore it is recommended that the gates be closed as soon as
practical, allowing the lake to fill in order for the water quality to stabilized.
GPWS does not recommend or promote recycling of water plant wastewater. Once the contaminants
_ are removed, it is preferred that there not be a chance for reintroduction into the water treatment cycle.
Also, PWS does not object to the discharge of water plant wastewater, properly treated, back into the
reservoir (for maximum dilution) below the raw water intake.
• . The proposed trcalment facility will consist orconventional water treatment followed by granulated
N activated carbon (GAC). Since conventional treatment, with GAC, is an acceptable and proven
method of treatment, no pilot work will be needed for the membranes as they will be "polishing" the
water for enhanced water quality. Please note that the rated capacity of the plant will be based on its
conventional treatmcntcapabilities.
• Approval for clearing and grubbing of reservoir is required prior to impoundment. Pest Management,
P WS's sister agency in the Division of Envirorimental Health, must approve the mosquito control for
the lake.
Copy of final environmental assessment approval must be forwarded prior to plans and specifications
approval.
` — If you have any questions or concerns related to the above, please advise.

Charles,

Seems like I always keep coming back to you for info and help. So I start off by thanking you.

/ e'�
G�/`l� �
I am trying to check on the status of the NPDES permit for the PT Water Treatment Plant. We have made a couple of
submittals and our reviewer has been in and out and I think is leaving your division (Natalie Sierra). I made a second
re -submittal a couple of weeks ago and want to try and track it as close as possible.
The reason for the questions is - the WTP plans were originally submitted with treatment to re -cycle the water to the head of
the plant. Wayne Munden sent us a letter saying that he is against this practice and requested that we ask for a permit to
discharge, which we have done, 3 times now. Tony Chen has reviewed the WTP plans and his only comment is "will there be a
discharge permit issued" and if so he would like for me to revise the plans and take off the treatment we had shown for the
re -cycle.
Natalie said that it was likely that we would receive a discharge but I was not able to get an application in her hands that was
acceptable.
So back to my question about status and tracking. I want to make sure that what I turned in is acceptable, what the review time
might be, and how likely it is that we will receive the discharge permit. It will take me about a month to revise the WTP plans to
take off the decant treatment and return them to Tony Chen and I would like to finish that process and get that permit as soon
as possible.
Once again, thanks for your help. Please let me know if I need to do anything else or whether a trip to Raleigh to meet with the
appropriate people in your office would be advisable.

RE: Randleman Lake WTP
Guilford County
NPDES Permit Application
Return No. 2198
HUA No. RN0204/300
Dear Ms. Sierra:
We are in receipt of your letter dated July 11, 2003. We have modified the NPDES Permit
Application and prepared the following response to the comments made in your letter:
1. Streamflow Data: Streamflow data is readily available based on the EIS that was
prepared for the construction of Randleman Lake. This information is now included
in the Engineering Alternatives Analysis for this project.
2. Flow Justification: The treatment of surface water generates a residual sludge as
well as a decant. The normal discharge from a conventional treatment facility is
5% — 8% of the total flow treated. As has been discussed in the past, DEH has
requested that this flow not be recycled to the head of the plant. Therefore, a means
of discharge has to be provided for the water treatment plant decant.
The total volume of decant generated is based upon the total size of the water
treatment plant. The maximum decant that can be anticipated would be 10% of the
total flow of the treatment plant. The Randleman Lake WTP has been sized based
on the participants needs. The water treatment plant capacity designed and
submitted to DEH for permitted is 12 million gallons per day that can be expanded
to 18 million gallons per day. The application for the NPDES discharge permit is
based upon an 18 MGD capacity of the facility. The total decant requested is 1.5
mgd.
A waste stream calculation is included in the Engineering Alternatives Analysis.

3. Flow Limit: As described above, maximum discharge anticipated from a surface
water treatment facility is 10% of the total flow. Under normal operation, the plant
should discharge between 5% — 8%. A waste stream flow calculation sheet is
attached estimating the decant generated at 12 and 18 MGD. The permit requests a
decant volume of 1.5 mgd.
4. Process Flow Diagrams: We are unaware of any discrepancy between the project as
describes to the Division of Water Quality and DEH. We have included a process
diagram that described the water treatment plant process as well as the sludge
handling process. If an NPDES discharge permit is issued for this project, the only
process that will be eliminated from the flow scheme will be the ultrafiltration
membrane treatment on the sludge handling process. All other treatment processes,
will remain.
Membrane filtration is not a requirement for an NPDES discharge permit on a
surface water treatment plant decant.
Description of Water Supply and Source Water Data: The water supply and source
water for the Randleman Lake Water Treatment Plant is Randleman Lake. The
source of this water is the Deep River and a sample has been taken of the Deep
River as part of the water treatment plant design. The results of this sample are
attached for your review.
6. Predicted Effluent Levels: The samples that have been taken on the Deep River do
not raise any concerns regarding metals. The only anticipated discharge that could
be anticipated is aluminum and chlorine as a result of the backwash water utilized.
If required, sample results from the decant of surface water treatment plants in the
area such as High Point, can be provided for your review.
Map: A map was provided in the application that showed the location of the water
treatment plant and the discharge point. An additional map will be provided that
shows the entire area of the Randleman Lake.
8. Present Value Costs: The present value costs have been calculated using a 20-year
evaluation period. This information is now included in the engineering alternatives
analysis. The discount rate was estimated at 5%; however, the discount rate is
relative for all alternatives and does not affect the outcome. We have requested an
interest rate and received an estimated interest rate for a project similar to this of
5%. This information will be utilized in the present value cost analysis.
9. Land -Based Disposal Alternative: We have included the calculations for the land
based disposal alternative. The cost for the property was derived from the cost fgr
the water treatment plant site. With regards to the need for additional operation
staff, the application of 1.5 MGD of wastewater in an irrigation type for subsurface
arrangement that includes 770 acres requires additional staff as well as additional
h:!projectsirn02031i00-permittingV-sierra denr 07-1603.doc

maintenance of the application area. It is anticipated that it would take a mechanic,
one half of his daily activities on average to maintain and monitor the operation of
the decant system.
10. Reuse Alternative: Reuse as defined as reuse on golf courses or similar applications
is not an available alternative at this location. Calculations have been performed
that increases the application rate based on the construction of a golf course. The
required construction in the area to accept 1.5 MGD of daily flow would be the
construction of four-18-hole golf courses. The area located around the water
treatment plant is completely undeveloped with no development activity
anticipated. Piedmont Triad Regional Water Authority will entertain any other
alternatives for reuse; however, no such alternatives are available that we know of at
this time.
11. Surface Disposal Alternative: All of the alternatives reviewed in the engineering
alternative analysis will utilize the same treatment units at the surface water
treatment plant including equalization lagoon, sludge thickening, and sludge
dewatering. The land based disposal alternative will require pump station, force
main, controls, and the irrigation distribution system in order to land apply the
water. The capital costs involved for the surface disposal alternative will only
require the construction of a parshall flume and the installation of a sampler in order
to meet the requirements for discharge.
We are unaware of the cost for annual fees for permitting of both this option and
surface water alternatives; however, they will be included in the attached submittal.
12. Engineering Alternatives Analysis: We have expanded our Engineering Alternatives
Analysis an explanation of the O&M costs for each of the alternatives. In addition,
we have prepared a detailed capital cost for each of the alternatives.
The contingency value for each of the alternatives was calculated as percentage of
the total O&M cost. A similar contingency value was placed on the O&M cost
evaluation for the operation of the complete facility and the contingency value was
included for consistency.
We understand that you will be leaving your position with the Division of Water Quality. Hobbs,
Upchurch & Associates would appreciate the opportunity to meet the reviewer assigned to this
project as soon as possible to review this application. The information requested in the July 11,
2003 correspondence could have been an amendment to the revised application that was
submitted in May. We are concerned that the issuance of this permit is delaying the issuance of the
water treatment plant permit. We would like to coordinate the review of this application with you
in order to provide information to Mr. Tony Chen regarding the possible issuance of a discharge
period. We will call to set up a meeting with you to review this submittal.

Subject: NPDES Permit application
Randleman Lake WTP
Guilford County
Return # 2198
In accordance with Division policy, we must hereby return the attached permit
application. After a preliminary review by a member of the NPDES staff, the Division has
determined that the application package lacks the following items:
• Streamflow data - No streamflow data were provided for the proposed
receiving stream. 7Q 10, 30Q2 and average flows may be obtained from the
USGS and must be provided in order for this application to be complete. You
may contact Mr. Curtis Weaver of USGS at [phone] for more
information.
Flow justification - Please justify the need for this discharge as well as
providing calculations for the proposed flow. For example, how many
customers is this system intending to serve and what is the backwash to
potable water ratio?
Flow limit - This permit will contain a flow limit. As described above, using
demand and treatment process information, please predict the waste flow
that will be generated by this system. This number will be reviewed and if it
is reasonable, will be used as the flow limit in the permit.
• Process flow diagrams - There seems to be a discrepancy between the
project as it has been described to DWQ and DEH. Please provide a detailed
description of the water and wastewater treatment facilities, accompanied by
a diagram. Clarify specifically what type of membrane filtration is proposed
and what the predicted removal efficiencies will be.
Description of the water supply and source water data - While it is
assumed that the source will be the proposed Randleman Dam, this is not
made clear in your application. Please provide this information and source
water data.
Predicted effluent levels - Attempt to provide estimations, based on the
source water data, for effluent levels of metals and other toxicants.

• Map - Although you provided a map in your application, it would greatly aid
our assessment if you also delineated where the proposed Randleman Dam
is located relative to both your proposed discharge point and your intake.
• Present Value Costs - The Division requires a 20 year evaluation period for
the derivation of present value costs. Re -run your calculations using this
time frame. In addition, please provide the source for your discount rate.
• Land -based disposal alternative - Provide the loading rate calculations
including the amount of land needed for this option. Provide a source for the
cost of property in that area. Describe why a mechanic is needed for this
option, but not for any of the other options.
• Reuse alternative - The option described is not considered reuse, but
recycle. You are correct that DEH does not allow this as a disposal option,
but reuse should be allowed. This would include irrigation of a golf course,
for example.
• Surface disposal alternative - Explain why the cost of building treatment
units for this option has not been included. In addition, you have neglected
to include the cost of annual fees for permitting for both this option and the
land disposal option.
• Engineering Alternatives Analysis - Generally, the following are missing
from your EAA:
• An explanation/justification for the reasons why
contract services, repair parts, lab costs and vehicle
costs are different for the different alternatives
• An explanation for how the contingency value was
determined for each alternative.
• Capital costs for the different systems.

Division of Water Quality
SUBJECT: Review of EA for the Piedmont Triad Regional Water Authority - Randleman WTP
DENR#1179; DWQ#13034
The Division of Water Quality (Division) has reviewed the subject document. The Piedmont Triad Regional
Water Authority (PTRWA) proposes to construct a 12-MGD water treatment plant, a water intake on
Randleman Lake, and pipeline to convey water from the intake to the plant. The Division's comments on the
document are as follows:
• On page 27, only the lake buffer area adjacent to the project site can be used in calculating the built upon
area (BUA). The attached memo from Steve Zoufaly addresses this issue further. In addition, the memo
clarifies the identification of intermittent and perennial streams, and provides recommendations on
reuse/recycling.
• On page 29, the document discusses indirect and cumulative effects of the project, highlighting increased
nonpoint source pollution from increased urban development -within the PTRWA member service areas.
According to the proposal, the plant will serve Greensboro, High Point, Jamestown, Archdale, and
Randleman. Water quality rules for the Randleman Lake Water Supply Watershed will help to mitigate
the indirect and cumulative effects within the Randleman Lake watershed. In addition, the City of
Greensboro has adopted city-wide ordinances aimed at protecting water quality. However, the document
is not clear on the watershed protection ordinances of the other PTRWA members. More specifically,
mitigation measures within service areas outside of the Randleman Lake watershed are not discussed in
sufficient detail.
• The memorandum from Greensboro Storm Water Services (page 3 of Appendix B) states that "[f]orested
riparian buffers are not mandated by the State." To clarify, rules for protection and maintenance of
riparian buffers within the Randleman Lake Water Supply Watershed require a 50-foot buffer, except for
new development activities using the high density option (15A NCAC 02B .0250). Zone 1 of this buffer
(30 feet), immediately adjacent to the stream, consists of undisturbed vegetation. Zone 2 (20 feet) is
intended to provide diffusion and infiltration of runoff. Periodic mowing is allowed within Zone 2 so that
a grassed buffer is acceptable. The undisturbed vegetation within Zone 1 typically consists of forest
vegetation including woody and herbaceous species. Generally speaking, when left to regenerate
naturally, forest vegetation will colonize the area.
I may be contacted at 919.733.5083 x555. Thank you for the opportunity to comment on this project.

Memorandum
TO: J. Todd Kennedy
FROM: Steve Zoufaly
DATE: March 19, 2002
SUBJECT: Environmental Assessment Comments (DWQ# 13034)
Piedmont Triad Regional Water Authority Randleman Lake
Water Treatment Plant, Randolph County
have reviewed the Environmental Assessment for the proposed Piedmont .Triad Regional
Water Authority's Randleman Lake Water Treatment Plant in Randolph County. The facility
is proposed to be located in the Randleman Lake WS-IV Critical Area. Under the state's
rules for this area of the watershed new development cannot exceed six percent. -.
impervious surface area without the use of engineered stormwater controls. Clustering of
development is allowed on a project site. However, development cannot be averaged, as
proposed on page 27 of the document, using the buffer around the lake to offset the
proposed built upon area (BUA). If the proposed development exceeds six percent BUA for
the project site, then either additional land needs to be purchased adjacent to,the project
site on that the im ervious surface e f th "t t I th t -
p ar a or a si a is six percen or ess, or a projec
must have engineered stormwater control devices, such as wet detention basins, to
capture the stormwater runoff from the site.
On page 26 of the document, reference is made to the USGS and Soil Survey maps. For
clarification, both maps are used when making assessments of when riparian areas are
required. It's not a choice of one map or the other. For example, if a stream appears on
one and not the other, then a riparian area is required, unless field verification by DWQ
indicates that there isn't a stream on the site Also, why is it necessary to clear an area of
the 200-foot buffer for future facility expansion? Why not leave the buffer in natural
vegetation until it is needed for development since this should provide better protection?
Although it is stated on page 22 that wastewater reuse/recycling is not included in the
document since it was already addressed in the Randleman Lake EIS, it is an important
consideration for the Piedmont Triad Regional Water Authority. Even if this WTP is
constructed, the local governments should be actively pursuing wastewater
reuse/recycling. Rather than using potable water for irrigation or cooling water, for
example, reuse water could be provided. Also, communities should consider recycling their
treated wastewater back to their reservoirs.
Thank you for the opportunity to comment.
If you have any questions, please let me know.
