Subject: Issuance of Permit Modification
NPDES Permit NCO063096
Utley Creek WRF
Wake County
Class IV Facility
Division of Water Quality (Division) personnel have reviewed and approved your application for a
major modification of the subject permit. Accordingly, we are forwarding the attached NPDES
discharge permit. It is issued pursuant to the requirements of North Carolina General Statute 143-
215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental
Protection Agency dated October 15, 2007.
This final permit contains the following changes from the previously -issued permit:
• The permit supplement sheet and map was modified to include the new outfall location and the
expanded discharge. The new outfall will be designated as outfall 002.
• New effluent limitations pages were added for design flows of 6.0 MGD and 8.0 MGD.
• The priority pollutant scan requirement was changed from annual to three times during the
current permit term, consistent with the Division's policy for major municipal wastewater
treatment facilities.
• Because of site -specific concerns, instream sampling downstream of outfall 002 (designated
as site D1) and at the White Oak arm of Harris Lake (D2) may not be waived or exempted by
participation in the Middle Cape Fear River Basin Association monitoring program. This
sampling remains your responsibility from the start of discharge from outfall 002 for the
duration of this permit.

2. Effluent and instream monitoring shall be conducted on the same day.
Outfall 002 (expanded 6.018.0 MGD discharge):
Instream sampling shall be done directly upstream of outfall 002 (designated as U1). The parameters,
monitoring frequency, and sample types shall be identical to the table above.
Outfall 001 and Outfall 002
As a participant in the Middle Cape Fear River Basin Association (MCFRBA), the instream monitoring
requirements as stated above are waived. Should your membership in the agreement be terminated,
you must notify the Division immediately and the instream monitoring requirements specified in this
permit will be reinstated.
Utlev Creek Downstream and Harris Lake Suecial Monitoring Condition (Outfall 002
Twice per month downstream sampling, from May to September only, is required on Utley Creek
(designated D1) for surface grab samples of dissolved oxygen, temperature, conductivity, and pH.
Twice per month downstream sampling, from May to September only, is required on the White Oak arm
of Harris Lake (132) for the following parameters: depth profiles of dissolved oxygen, temperature,
conductivity, and pH; and photic zone composite sampling for total phosphorus, total nitrogen (NO2+
NO3 + TKN), and chlorophyll -a. Site D1 shall be located at least 200 feet downstream of the outfall; site
D2 shall be co -located with Progress Energy's Shearon Harris monitoring station designated "S2" as
used in previous Harris Lake modeling efforts.
Because of site specific concerns, sampling at these locations may not be waived or exempted by
participation in the MCFRBA monitoring program. These data may be collected and submitted by the
MCFRBA but remain the responsibility of the permit holder from the start of discharge from outfall 002 for
the duration of this permit.

A (5) CAPE FEAR BASIN NUTRIENT REOPENER
Pursuant to N.C. General Statutes Section 143-215.1 and the implementing rules found in the North
Carolina Administrative Coda at 15A NCAC 21-I.C112 (b) (1) and 2H.C114 (a} and Part 11 sections B-12
and B-13 of this permit, the Director of DWQ may reopen this permit to require supplemental nutrient
monitoring of the discharge. The purpose of the additional monitoring will be to support water quality
modeling efforts within the Cape Fear River Basin and shall be consistent with a monitoring plan
developed jointly by the Division and affected stakeholders. In addition, the results of water quality
modeling may require that additional limits for total nitrogen and total phosphorus be imposed in this
permit upon renewal.
A (6) CALCULATION OF TOTAL NITROGEN AND TOTAL PHOSPHORUS LOADS
a. The Permittee shall calculate monthly and annual TN and TP Loads as follows:
L Monthly TN (or TP) Load (lblmo) = TN (or TP) x TMF x 8.34
where:
TN or TP = the average Total Nitrogen (or Total Phosphorus)
concentration (mg/L) of the composite samples collected
during the month
TMF = the Total Monthly Flow of wastewater discharged during the
month (MG/mo)
8.34 = conversion factor, from (mg/L x MG) to pounds
ii. Annual TN (or TP) Load (Ib/yr) = Sum of the 12 Monthly TN (or TP) Loads for the calendar
year
b. The Permittee shall report monthly Total Nitrogen and Total Phosphorus results (mg/L and Ib/mo)
in the discharge monitoring report for that month and shall report each year's annual results (lb/yr)
in the December report for that year.
A (7) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality
to Ceriodaphnia dubia at an effluent concentration of 90 %.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the
"North Carolina Cedodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or
subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised -February 1998) or subsequent versions. The tests will be performed during the months of
February, May, August, and November. Effluent sampling for this testing shall be performed at the
NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below the
permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the two
following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure" (Revised -February 1998) or subsequent versions.

Permit NCO063096
The chronic value for multiple concentration tests will be determined using the geometric mean of the
highest concentration having no detectable impairment of reproduction or survival and the lowest
concentration that does have a detectable impairment of reproduction or survival. The definition of
"detectable impairment," collection methods, exposure regimes, and further statistical methods are
specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure'' (Revised -
February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the months in which tests were performed. If reporting pass/fail
results using the parameter code TGP313, DWQ Form AT-1 (original) is sent to the below address. If
reporting Chronic Value results using the parameter code THP313, DWQ Form AT-3 (original) is to be
sent to the following address:

Hi Gil,
As we just discussed and at your request; please consider this email your notice of "no comments" for the issuance of this
modification of the draft permit for the Holly Springs VW TP in Wake County, NC. NPDES No. NC0063096.
The final permit is for the expansion to 8.0 MGD and will include additional instream monitoring as detailed in the permit
and just discussed on the phone.
As always if any substantial changes that we have not discussed are made to the permit prior to final issuance NC DWQ
will forward those changes to EPA Region 4 for another review.
In the meantime, please issue this permit as your scheduling allows and please forward to EPA a final signed document.
Thank you,
Pamala Myers

Hi, Pam:
As I indicated in the voice mail message, we are seeking concurrence with the Holly Springs expansion permit.
You may remember that you were OK with the draft. The final is attached. The only difference from the draft
is that it has an interim 6.0 MGD phase (same limits as 8.0 MGD ultimate flow), and also more stringent
instream monitoring requirements.
Thanks,
Gil

Summary
• The NPDES permit for The Town of Holly Springs Utley Creek Water Reclamation
Facility (WRF) was recently renewed, with an effective date of November 1, 2011.
Because the town is experiencing rapid growth, it has now requested an increase in
treatment capacity to 8.0 MGD. The town chose not to pursue a regional approach to
wastewater treatment when it withdrew its membership from the Western Wake
Partnership in September 2010.
• After obtaining approval from the Division to relocate the outfall to a point further
downstream in Utley Creek from its present site, the town obtained a speculative limit
letter for flows of 6.0 and 8.0 MGD on June 24, 2011. This new discharge point is
located downstream from impoundments with algae problems caused by nutrients,
particularly Thomas Millpond.
• The town submitted a detailed EAA with this flow expansion request. It provided
background on the Utley Creek WRF, justified design flow, and discussed alternatives in
detail. These included no action, optimum operation of existing facilities, a Harnett
County regional interconnection, the Western Wake Regional WRF tie-in option, and the
selected choice, plant expansion and outfall relocation. The town received a FONSI
(finding of no significant impact) for an 8.0 MGD discharge at this discharge point on
September 28, 2011.
• The Division has concurred with the conclusions of the EAA and the FONSI regarding
the justification of an 8.0 MGD discharge flow and the alternatives analysis. The service
area for this treatment plant was shown to be one of the fastest -growing population
centers in North Carolina. The EAA satisfied the requirements of the DWQ
antidegredation policy (15A NCAC 2B.0201), which requires applicants for NPDES
Fact Sheet
NPDES Permit Modification NCO063096
Page 1

permit expansions to consider non -discharge alternatives pursuant to 15A NCAC
2H.0105(c) (2).
• At the request of the town, the draft permit was revised to add a 6.0 MGD effluent page.
Permit Limits Development
A speculative limits letter for the expanded flow was issued to the town on June 24, 2011. The
limits for the 8.0 MGD design flow at new outfall 002 are consistent with this letter:
Nutrient Limits (monthly averaged: 5.0 mg/L TN; 0.5 mg/L TP; and 0.27 mg/L Orthophosphorus,
based on a nutrient -response model developed for discharges to Harris Lake. The model
indicates that Harris Lake is highly sensitive to phosphorus. In keeping with the permit strategy
for the Cape Fear River Basin, Weekly TKN and Nitrate/Nitrite Species monitoring is proposed.
Conventional Parameters: BOD (5.0 mg/L monthly average), NH3-N (1.0 mg/L monthly
average); and DO (7.0 mg/L minimum as a daily average). Modeling indicates that there is very
little impact on the DO concentrations in the hypolimnion of Harris Lake using these proposed
limits.
No changes were made to the permit limits for the existing 2.4 MGD discharge flow at existing
outfall 001. This permit was renewed October 12, 2011.
Instream Monitoring
Regarding instream monitoring, no changes are proposed for the present monitoring at the
existing 2.4 MGD outfall 001. However, for the expanded flows at outfall 002, the monitoring
downstream in Utley Creek (designated site D1) and at the White Oak arm of Harris Lake (D2),
will be required to be accomplished by the permittee regardless of its participation in the Middle
Cape Fear River Basin Association monitoring program. Because of site specific concerns, this
sampling remains the responsibility of the permit holder from the start of discharge from outfall
002 for the duration of this permit.
Proposed Changes to the Permit
To accommodate this requested expansion, the following modifications are proposed:
• Effluent flow tables for 8.0 MGD and 6.0 MGD were added. Permit limitations will be
consistent with the speculative limit letter issued for this amount of flow.
• The supplement sheet was updated to reflect the expanded flow, including a revised
map with the location of the new outfall (designated as outfall 002).
• The priority pollutant scan requirement was changed from annual to three times during
the current permit term, consistent with the Division's policy for major municipal
wastewater treatment facilities.
• Because of site -specific concerns, instream sampling downstream of outfall 002 in
Utley Creek (designated as site D1) and at the White Oak arm of Harris Lake (D2) may
not be waived or exempted by participation in the Middle Cape Fear River Basin
Association monitoring program.

To: Gil Vinzani; Complex NPDES Permits Unit
From: Planning Section
Re: Request for modification to the propose Holly Springs NPDES permit monitoring
requirement.
As part of the SEPA review process done by the Planning Section, comments were made
indicating the need for special monitoring requirements to be placed in the Holly Spring NPDES
permit that go above and beyond their existing permitting requirements. These special
requirements were requested due to the uncertainties associated with the model done by the
Town of Holly Springs for the direct purpose of discharging wastewater into Utley Creek. These
additional monitoring requirements are to ensure that the new discharge does not have a
negative impact on water quality in the lower portion of Utley Creek below outfall 002 and in the
White Oak Creek Arm of Harris Lake.
In an email from Tom Belnick to Nora Deamer and Hannah Stallings (September 15, 2011), he
concurs with the need for additional instream monitoring to include one station downstream in
Utley Creek and one in White Oak Creek Arm (Harris Lake).
We request the inclusion of additional instream monitoring parameters to section
A(4) INSTREAM MONITORING REQUIREMENTS:
Conductivity, pH and Turbidity - using the current proposed measurement frequencies, sample
type and sample location.
These recommendations would be specifically for the Outfall 001 (existing 2.4 MGD
dischar e) & Outfall 002 (expanded 6.018.0 MGD discharge) subsections.
Subsection Outfall 001 and Outfall 002 would remain the same as it is.
Subsection Harris Lake Special Monitoring Condition (Outfall 002):
Proposed language for the "Special Monitoring Condition" segment of the permit:
Utley Creek and Harris Lake Special Monitoring Condition (Outfall 002)
Twice per month downstream sampling, from April to October only, is required on the Utley
Creek (D1) and White Oak arm of Harris Lake (designated D2). Monitoring requirements on
Utley Creek (D1) for the following parameters: dissolved oxygen, temperature, conductivity, pH
and turbidity. Monitoring requirements on the White Oak Creek arm of Harris Lake for the
following parameters: dissolved oxygen depth profiles, temperature, conductivity, pH, turbidity
and photic zone composite sampling for total phosphorus, orthophosphate, total nitrogen, and
chlorophyll -a. Because of site specific concerns, sampling at this location may not be waived or
exempted by participation in the Middle Cape Fear River Basin Association monitoring program.
This sampling remains the responsibility of the permit holder from the start of discharge from
outfall 002 for the duration of this permit.

We also request that any data not collected through the coalition be submitted to the division
electronically along with the analytical QA/QC data. This will insure the use of this data by the
division for the purposes of assessing water quality and insuring the continued protection of
these resources.

Since July 1998, the Middle Cape Fear River Basin Association has monitored the Cape Fear watershed from the
confluence of the Haw and Deep Rivers to Lock and Dam One. Today the association monitors thirty-five stations
monthly for water quality parameters such as dissolved oxygen, fecal coliform, and chlorophyll a. The monitoring
plan can be found in the association's Memorandum of Agreement (MOA) with DWQ
The MCFRBA have helped expand water quality knowledge within the watershed through supporting academic
research and conducting studies on fecal coliform and low level metals.

— Permit Modification Request
Dear Mr. Belnick:
I have enclosed three copies of the Town of Holly Springs NPDES permit
modification request for the Utley Creek Water Reclamation Facility (NC0063086).
The permit modification includes two issues:
• Relocate the outfall from its current location on Utley Creek to a
downstream location on Utley Creek below Greentree Reservoir
• Increase in permitted capacity from 2.4 mgd to 8 mgd
The Town completed an Environmental Assessment (EA) for these actions, and a
Finding of No Significant Impact was issued on November 9, 2011. An
Engineering Alternatives Analysis (EAA) was completed as part of the EA process;
I've enclosed one copy of the EAA.
Our NPDES permit was recently renewed on October 12, 2011 with an effective
date of November 1, 2011. Thus this application package does not include
monitoring data which was provided to you in January 2011 as part of the permit
renewal process.
If you have any questions or need additional information, please contact me at
[phone] or Daniel Weeks, Interim Public Utilities Director at [phone].

FINDING OF NO SIGNIFICANT IMPACT AND ENVIRONMENTAL ASSESSMENT
TOWN OF HOLLY SPRINGS — UPGRADE AND EXPANSION AND DISCHARGE
RELOCATION FOR THE UTLEY CREEK WATER RECLAMATION FACILITY
Pursuant to the requirements of the North Carolina Environmental Policy Act (N.C.G.S. § 113A-1, et
seq.), an environmental assessment (EA) has been prepared for the Town of Holly Springs (The Town)
for a proposed expansion and upgrade of Holly Springs' Utley Creek Water Reclamation Facility
(UCWRF) from 2.4 million gallons per day (MGD) to 8 MGD. Expansion to this capacity and treatment
process upgrades will consist of a supplemental carbon feed system; coagulation basin and additional disc
filter; upgraded coagulant feed system; reclaimed water pumping and effluent measurement equipment;
and biosolids handling upgrades (decant clarifier, additional storage tank, and sludge dewatering
facilities). The Town will also install approximately 11,700 feet of 48-inch pipe to relocate the UCWRF
discharge downstream of the currently permitted discharge location to Lower Utley Creek within the
potential future pool elevation of Harris Lake.
Four alternatives for treating the forecasted 20-year flows for the projected service area are considered in
the EA: (1) no action; (2) optimum operation of existing facilities; (3) regional solutions (connection
with the North Harnett Regional facility or connection with the Western Wake Regional facility); and
(4) expansion and upgrade of the UCWRF. Upon consideration and evaluation of each alternative, the
fourth treatment alternative was found to be the most viable. Four alternatives for the discharge of the
increased wastewater flows are considered in the EA: (1) Cape Fear River discharge; (2) Lower Utley
Creek discharge; (3) land application; and (4) wastewater reuse. Upon consideration and evaluation of
each alternative, the second alternative was found to be the most viable for effluent disposal.
All treatment plant process improvements and infrastructure necessary for facility expansion will be
constructed on previously disturbed land on the existing UCWRF site. While construction of the new
facilities may result in temporary increases in sedimentation and erosion, noise levels, and dust in the
immediate vicinity of the construction area, these and other direct impacts have been avoided and
minimized to the extent practicable during project planning and design. Approximately 15 acres will be
impacted by construction. Topography within the existing UCWRF site will be altered by grading, and
construction of the effluent line will not alter existing topography since the line will be buried beneath the
ground and disturbed areas returned to original grades. Contractors will utilize best management
practices specified in an Erosion and Sediment Control Plan to limit soil loss, erosion, and the possibility
of spillage during construction. Land use changes involve the creation of permanent utility easements
varying from 10 to 40 feet along the outfall line. Nearly 14 acres of forested area will be clear cut for
construction and access; a more limited maintenance corridor will remain permanently cleared. The
permanently maintained corridor would be re -vegetated with a mix of wheat, clover, and warm season
grasses or their equivalent, depending on availability of specific seed stocks at the time of construction
and as long as the recommendations would provide sufficient stabilization to not impact construction
progress. The temporary construction easements will be allowed to naturally regenerate to forest.
Approximately 0.1 acres of wetland will be impacted by the proposed project; 0.04 acres would be
allowed to revert to pre -construction conditions and the remaining 0.06 acres would be permanently
maintained as herbacous wetland. Installation of the effluent outfall will require seven stream crossings,
which will be accomplished via directional drilling unless this method is not practicable. Although the
project will impact 3.5 acres of the Harris Lake Gamelands, the presence of a utility corridor in this large
area of forest should not result in a significant impact. Wildlife distressed by construction are expected to
relocate to surrounding forested areas. To minimize water quality impacts from oil, fuel, and emissions
from construction equipment, contractors will be required to perform maintenance activities in designated
areas away from surface waters and wetlands and to collect and properly dispose of all used vehicle fluids

and containers. Construction activities will be limited to daylight hours and avoid weekends and holidays
and normal operation of the expanding facility and new discharge line should not significantly increase
local ambient noise levels. The proposed project should not result in significant long term negative direct
impacts on the 100-year floodplain; prime or unique agricultural lands; air quality; areas of archaeological
or historic value; groundwater; and shellfish or fish and their habitats. Also, the proposed project should
not result in the introduction of any toxic substances during either the construction or operation of the
facility.
This project should reduce nutrient loading within the upper reaches of Utley Creek. However, water
quality monitoring shall be included as part of the NPDES permit to ensure that the discharge does not
have a negative impact on water quality downstream, The Town and the Division of Water Quality will
coordinate efforts once the Finding of No Significant Impact is issued to develop a monitoring plan to
ensure that any potential adverse impacts to Utley Creek and Hams Lake are detected promptly so that
the UCWRF discharge can be adaptively managed.
The Town has agreed to implement the following recommendations from the North Carolina Wildlife
Resources Commission to minimize direct impacts to aquatic and terrestrial wildlife resources:
• The effluent pipe, manholes, and appurtenances will be installed and tested in accordance with
State regulations and industry standards for sanitary sewer lines. The pipe segments located
within the noted 50-foot and 100-foot setbacks will be constructed of ductile iron or comparable
material.
• Quarterly monitoring will be completed for the first 12 months under the construction contract to
ensure the areas are stabilized. After that time, the route will be on an annual monitoring schedule
in compliance with the Town's collection system permit.
• Unless unusual and specific circumstances apply, which are not anticipated at this time, no
pesticides will be used in the corridor.
• The recommended seeding mix and habitat creation measures will be included in the construction
contract. The nesting windows will be communicated to the Town's maintenance staff, and
mowing will be performed outside nesting windows when practicable.
Secondary and cumulative impacts that may result from the expansion of the UCWRF will be managed in
accordance with the Town's Secondary and Cumulative Impacts Master Mitigation Plan.
Based on the findings of the EA, the impact avoidance/mitigation measures contained therein, and review
by governmental agencies, the Division of Water Quality has concluded that the proposed project will not
result in significant impacts to the environment. This EA and Finding of No Significant Impact are
prerequisites for the issuance of Division of Water Quality permits necessary for the project's
constriction. An Environmental Impact Statement will not be prepared for this project. This FNSI
completes the environmental review record, which is available for inspection at the State Clearinghouse.
