Permit NC0066966
Quarterstone Farm WWTP
Guilford County
Dear Ms. Johnson:
Consistent with the Director's October 1, 2009, letter of intent to modify NPDES permits affected by the
Jordan Reservoir Nutrient Management Strategy rules and in consideration of public comments on the
subsequent draft permit modifications, the Division is forwarding herewith the revised NPDES permit
for the Quarterstone Farm WWTP. This permit modification 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.
The Division received no comments on the draft permit during the initial public comment period and is
issuing the permit with the proposed modifications. However, we did receive comments from several
permittees regarding the standard permit conditions (Parts II, III, and IV) in the draft permits. In
response, Jeff Poupart of the Point Source Branch has worked with other programs within the Division
and with EPA Region 4 staff to evaluate and address those comments. The final permit includes the
resulting version of the standard conditions. We regret any inconvenience this delay may have caused.
Implementation of Total Phosphorus (TP) Limits. The Jordan Reservoir Wastewater Discharge
Requirements (T15A NCAC 02B .0270) established annual mass phosphorus limits for fourteen
treatment facilities, to become effective with calendar year 2010. Thus, even though the effective date of
this permit modification is August 1, 2010, the new limits became effective January 1, 2010, by rule and
apply to calendar year 2010 in its entirety.
If any parts, measurement frequencies, or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty
(30) days following receipt of this letter. This request must be in the form of a written petition,
conforming to Chapter 150B of the North Carolina General Statutes, and filed with the office of
1617 Mail Service Center, Raleigh, North Carolina 27699-1617

14 NPDES Permits
PROPOSED PERMIT ACTION
In November 2009, the Division proposed to modify fourteen (14) NPDES permits for
municipal and domestic treatment facilities in the Jordan Lake watershed of the Cape Fear
River Basin. The purpose of the modifications was to set Total Phosphorus discharge limits in
accordance with the Jordan Lake Nutrient Management Strategy: Wastewater Discharge
Requirements, T15A NCAC 02B .0270.
TORDAN LAKE NUTRIENT MANAGEMENT STRATEGY
The Jordan Lake Nutrient Management Strategy is a comprehensive set of rules and Session
Law that became effective August 11, 2009. The Strategy aims to restore and maintain water
quality, protect the lake's classified uses, and maintain or enhance protections currently
implemented by local governments in existing water supply watersheds. The Strategy calls for • • •
improvements in stormwater management (existing and new development), agricultural
practices, fertilizer application management, riparian buffers protection, and wastewater
treatment.
The Strategy establishes nitrogen and phosphorus allocations for all existing wastewater
dischargers that treat nutrient -bearing wastes. For point sources, it specifies that facilities with a
permitted flow of 0.1 MGD or greater must meet nutrient limits based on these allocations. The
limits for both nitrogen and phosphorus are given as annual mass limits. The phosphorus limits
become effective in CY2010, the nitrogen limits in CY2016.
The figure below shows the watershed and the three subwatersheds. The strategy sets nutrient
reduction targets for each subwatershed.
PROPOSED PERMIT MODIFICATIONS
The proposed permit modifications affect the fourteen dischargers affected by the new rule,
and these are listed below. (The list once included a fifteenth permit, NC0003913 for Glen
Raven Inc., but that has been rescinded since work began on the Strategy and so is not listed.)
The modifications add a new Special Condition to each permit to identify the discharge and
delivered allocations and the Transport Factor for the permitted facility. The permits include
the new annual mass discharge limits for phosphorus, equal to each facility's TP discharge
allocation. The Division intends to add nitrogen limits during the 2011 permit renewals.
The attached table lists all facilities in the Jordan Lake watershed that received nutrient
allocations under the Wastewater Discharge Requirements rule. It shows the allocations,
transport factors, and permitted flow for each facility. It also shows the equivalent
concentrations for the TN and TP allocations, that is, the concentration that the facility must
reach to meet its mass limit at full permitted flow.
Some of the modifications include other, minor changes. For example, conditions were re-
ordered to group the nutrient -related conditions for easier reference.

PUBLIC COMMENTS
Several permittees submitted comments specific to their permits. Among these:
• OWASA noted that special monitoring for cyanide and mercury had been completed and
that sample type for ongoing monitoring was incorrectly shown as Composite; the special
condition was removed and sample type corrected.
• Durham County pointed out that the optimization requirement does not apply to its
Triangle facility because it has already made capital improvements to meet the new Jordan
nutrient limits. The condition was removed.
EPA had no comments or objections regarding the draft permits; neither did DEH. No other
public comments were received.
When one permittee questioned one of the standard permit conditions, it came to light that the
permits been mailed with an out-of-date version of the boilerplate. The Division distributed the
current version, which was itself a 2009 update, and granted another 30-day comment period.
This prompted closer scrutiny, and several permittees then took issue with other of the
standard conditions, particularly the pretreatment conditions in Part IV. Jeff Poupart of the
Point Source Branch worked with other programs within the Division and with EPA Region 4
staff to evaluate and address the comments received. This led to a newly revised version of the
standard conditions, which was included in the final permits.
Greensboro and Burlington asked for permit limits combining, in each case, the City's two
allocations into a single over -arching limit. Further action was delayed pending the outcome of
the standard conditions issues.
FINAL ACTION
Ten of the fourteen permits will be issued as proposed, except that they will have the newly
revised standard conditions and some will be revised based on comments. The Greensboro and
Burlington permits will be revised to include joint limits and will be sent to public notice again.

Dear Mr. Caviness:
October 1, 2009
Notification of Intent to Modify NPDES Permit NC0066966
to Incorporate Jordan Lake Nutrient Requirements
Quarterstone Farm WWTP
Guilford County
Governor Bev Perdue recently signed legislation to complete passage of rules for the Jordan Lake
Nutrient Management Strategy. The Strategy includes a Wastewater Discharge rule (T15A NCAC 02B
.0270) that applies to your wastewater treatment facility. Pursuant to Sub -Item (6)(d) of that rule, I am
writing to notify you of (1) the nutrient allocations assigned to your facility and (2) the Division of
Water Quality's intent to modify the facility's NPDES permit to include nutrient limits as provided in
the rule. I also wish to remind you of other provisions of the rule that require your prompt attention.
This letter addresses only certain provisions of the Jordan Lake Wastewater Discharge rule. I encourage
you to familiarize yourself with the remainder of this rule.
Nutrient Allocations. The Wastewater Discharge rule establishes the maximum loads of nitrogen and
phosphorus that can be released from wastewater treatment facilities into the Jordan Lake watershed.
The rule specifies that these wasteload allocations are to be divided among the existing facilities in
proportion to their 2001 permitted flows (with certain exceptions).
Your facility has been assigned nitrogen and phosphorus allocations. The allocations are expressed as
annual mass loadings delivered to the lake. Due to foreseeable losses between the discharge point and
the lake, they are also expressed as the equivalent discharge loads at the point of discharge. The
delivered and the corresponding discharge allocations assigned to your facility are as follows:
NC0066966
Delivered Allocation
(lb/yr)
Transport
Factor (%)
Discharge Allocation
(lb/yr)
Total Nitrogen
1,609
50
3,218
Total Phosphorus

David Caviness, President
Notification of Intent to Modify NPDES Permit
October 1, 2009
Intent to Modify Permit. The new rule specifies that facilities with permitted flows at or above 0.1
MGD, including yours, will be subject to effluent limits for nitrogen and phosphorus. The effluent
limits will equal the facility's discharge allocations. The new phosphorus limits become effective
beginning with calendar year 2010. Nitrogen limits become effective beginning with calendar year
2016.
It is the Division's intent to modify the affected permits by the end of 2009 to include the new
phosphorus limits. We will draft permit modifications for the affected facilities in the coming weeks.
As with any such permit action, the proposed modifications will be subject to public review, and we
will provide you with a copy of the draft permit at that time.
The Division will add nitrogen limits during the 2011 permit renewals, with a compliance date of 2016.
Process Optimization. The rule specifies that no later than six months after its effective date, each
discharger with a permitted flow greater than or equal to 0.5 MGD must "evaluate its treatment
facilities and operations and identify further opportunities to improve and minimize nitrogen
reduction in the existing facilities...; and submit a report to the Division documenting its findings,
proposing optimization measures, and describing expected results."
Please provide three copies of your report to the Division at the following address no later than
February 11, 2010:
Division of Water Quality
Surface Water Protection Section, Point Source Branch
Attn: Jordan Lake Coordinator
1617 Mail Service Center
Raleigh, NC 20699-1617
Each discharger must implement the proposed .measures no later than six months after the Division
accepts the report and continue until such time as the facility is upgraded for nitrogen removal. The
affected dischargers must also submit annual progress report to the Division for a period of five years.
If you have any questions regarding these requirements, please contact Mike Templeton at (919) 807-
6402 or at [e-mail].
Sincerely,
en H. S ns
