Subject: Issuance of NPDES Permit NC0020354
Town of Pittsboro WWTP
Chatham County
Dear Mr. Misenheimer:
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES discharge permit. This permit 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 May 9,1994 (or as
subsequently amended).
This final permit includes no changes from the draft permit sent to you on October 25, 2006. You are
reminded of the following terms within this permit that are different from the one currently effective:
• A weekly average limit for ammonia has been added to the permit. Since December 2002, the
Division has been adding daily maximum limits for ammonia to permits with monthly average limits
in order to conform to federal NPDES regulations.
• Monitoring requirements have been added pursuant to the Division's Cape Fear River Basin
permitting strategy, which is primarily concerned with the discharge of nutrients in the Jordan Lake
watershed. These new requirements include monitoring/reporting for:
Total Kjeldhal Nitrogen (TKN)
Nitrates + Nitrites (NO2 + NO3)
Total Monthly Flow
Total Nitrogen Load (Monthly and Annual Loading)
Total Phosphorous Load (Monthly and Annual Loading)
The Town is currently monitoring for all of these parameters per the requirements of the existing
permit. The new requirements will call for different manipulations and/or displays of the data on
monthly reports.
• New narrative conditions [Sections A. (3) — A. (6)] have been added to address various aspects of
nutrient issues relevant to this discharge.

• A Total Residual Chlorine (TRC) daily maximum limit has been added. Since the issuance of the
existing permit, the North Carolina Environmental Management Commission has adopted rules
that establish a water quality standard for TRC. However, the condition within the permit remains
that TRC will only have to be monitored if chlorine is added as a disinfectant or used elsewhere in
the process.
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
Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-6714). Unless
such demand is made, this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may
require modification or revocation and reissuance of the permit. This permit does not affect the legal
requirements to obtain other permits which may be required by the Division of Water Quality or permits
required by the Division of Land Resources, the Coastal Area Management Act or any other Federal or
Local governmental permit that may be required.
If you have any questions concerning this permit, please contact Bob Sledge at telephone number (919)

Footnotes from Limits and Monitoring Requirements:
1. Sample locations: Upstream = at least 100 yards above the outfall; Downstream = at least 100 yards
downstream from the outfall. Instream monitoring shall be conducted 3/Week during June, July,
August, and September, and once per week during the remainder of the year.
2. The monthly average BOD5 and Total Suspended Residue concentrations shall not exceed 15% of
the respective influent value (85% removal).
3. The daily dissolved oxygen effluent concentration shall not be less than 6.0 mg/1.
4. Total residual chlorine shall be monitored if chlorine is added as a disinfectant or used elsewhere in
the process.
5. TN = TKN + NO3-N + NO2-N, where TN is Total Nitrogen, TKN is Total Kjeldahl Nitrogen, and
NO3-N and NO2-N are Nitrate and Nitrite Nitrogen, respectively.
6. TN or TP Load is the mass quantity of Total Nitrogen or Phosphorus discharged in a given period of
time. See Special Condition A. (4.), Calculation of Mass Loads.
7. See Condition A. (5.) for prospective Total Phosphorous summer effluent limit to be included in
future permits.

Permit NC0020354
A. (2.) 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 Ceriodaphnia 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, March, June, September, and December. 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.
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, using the parameter code TGP3B for the
pass/fail results and THP3B for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the
following address:
Attention: NC DENR / DWQ / Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later than 30
days after the end of the reporting period for which the report is made. Test data shall be complete, accurate, include
all supporting chemical/physical measurements and all concentration/response data, and be certified by laboratory
supervisor and ORC or approved designate signature. 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
cited above.
Should the pernuttee fail to monitor during a month in which toxicity monitoring is required, monitoring will be
required during the following month. Should any test data from this monitoring requirement or tests performed by
the North Carolina Division of Water Quality indicate potential impacts to the receiving stream, this permit may be
re -opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions.as specified in the cited document (such as minimum control
organism survival, minimum control organism reproduction, and/or appropriate environmental
controls) shall constitute an invalid test and will require immediate follow-up testing, to be completed no
later than the last day of the month following the month of initial monitoring.

Permit NC0020354
A. (3.) PERMIT RE -OPENER: SUPPLEMENTARY NUTRIENT MONITORING
Pursuant to N.C. General Statutes Section 143-215.1 and the implementing rules found in Title 15A of
the North Carolina Administrative Code, Subchapter 02H, specifically, 15A NCAC 02H.0112(b)(1) and
02H.0114(a), and Part II, 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 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.
A. (4.) CALCULATION OF MASS LOADS
a. The Permittee shall calculate monthly and annual TN (or TP) Loads as follows:
i. Monthly TN (or TP) Load (lb/mo) = 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
,I, =MF 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 (lb/yr) = Sum of 12 Monthly TN (or TP) Loads for calendar
year
b. The Permittee shall report monthly Total Nitrogen and Total Phosphorus results (mg/L
and lb/mo) in the appropriate discharge monitoring report for each month and shall report each
year's results (lb/yr) with the December report for that year.
A. (5.) TOTAL PHOSPHOROUS LIMITS IMPLEMENTING THE TOTAL MAXIMUM
DAILY LOAD (TMDL) FOR ROBERSON CREEK
A Total Phosphorous summer effluent limit consistent with the requirements of the TMDL for Roberson
Creek will be included in the permit issued to this facility for the next permit cycle and subsequent
permit cycles if and as long as the facility continues to discharge into Roberson Creek. As of the issue
date of this permit, the prospective summer limit at 0.75 MGD for Total Phosphorous will be 1.5 lbs/day
(an approximate 0.25 mg/L concentration equivalent). The Town will be expected take necessary
actions to ensure it will be compliant with such a limit by the expiration date of this current permit if the
discharge remains in Roberson Creek.
Please refer to the final Total Maximum Daily Load (TMDL) publication for Roberson Creek.

Permit NC0020354' •
A. (6.) TOTAL PHOSPHOROUS COMPLIANCE PLANS
By January 1, 2009, the Town of Pittsboro will submit a plan prepared by a professional engineer
documenting how it intends to satisfy the Total Maximum Daily Load (TMDL) that has been established
for Roberson Creek and/or Total Phosphorous permit limits imposed upon the Town of Pittsboro
WWTP based upon the TMDL or other nutrient management strategies for the Cape Fear River Basin.
The plan should include an analysis of projected growth for the Town and projected future wastewater
needs along with detailed discussion of how the Town plans to meet any needs for additional capacity
and remain in compliance with water quality regulations. The report should discuss any plans for
expansion of the WWTP, potential relocation(s) of the outfall and the effects these decisions may have
on both permitting issues and the actual water quality of the receiving stream. This report shall be
submitted to:

Re: Town of Pittsboro
Wastewater Plant Projects Update
Dear Mr. Sledge,
On behalf of the Town of Pittsboro, this letter is to provide information concerning the
wastewater projects currently underway in the Town of Pittsboro. Hobbs, Upchurch
and Associates (HUA) has been working closely with the Town since April of 2006 to
keep them up to speed in their wastewater treatment needs.
HUA is nearing design completion on a 600,000-gallon per day expansion of the current
wastewater plant. This expansion will sit on a parcel adjacent to the existing facility
and will feature nutrient removal technology to provide the highest quality effluent
available.
The short-term disposal for the effluent will be three -fold. First, approximately 143,000
gallons per day will be delivered to the 3M facility located just south of Pittsboro. This
water is evaporated by 3M during their dye process. Secondly, two new developments
in the Pittsboro area are requesting reclaimed water for golf course irrigation. Between
the two developments, approximately 350,000 gallons per day will be spray irrigated for
disposal. Between 3M and golf course irrigation, Pittsboro will obtain approximately
493,000 gallons per day of increased disposal capacity.
The final method of disposal will be the existing NPDES discharge permit (750,000 gpd)
into Roberson Creek. Discharge flow from the new plant will be mixed with the existing
flow prior to being discharged. Pittsboro currently averages approximately 350,000
gallons per day of wastewater, and in a perfect world, Pittsboro would divert all of the
current wastewater into the new facility and abandon the existing facility. However,
there may be a window in the flow demand where the treatment ability of the existing
plant is required to satisfy Pittsboro's incoming allocations. Hence, because of system
redundancy requirements, and because of troubles associated with resurrecting an
abandoned treatment facility, part or all of the existing wastewater plant will more than
Southem Pines, NC • Telephone [phone] • Fax [phone] • email: [e-mail]
Myrtle Beach • Nags Head • Raleigh • Charlotte • Beaufort

likely be left online. These are decisions that are currently being examined and
discussed with both the Town and the Division of Water Quality.
HUA is expecting to be ready for the Express Review process by November 1, 2006.
Construction could begin as early as March 2007, thus bringing the new plant online on
or around March 2008.
The new 600,000 gallon per day plant will be Phase 1 of a larger plant expansion. HUA
has begun the Environmental Impact Statement process to obtain an NPDES discharge
permit for 4.0 MGD to one of two proposed locations on the Haw River and Jordan
Lake. Once the EIS process is complete, design will begin for further expansion of the
new 600,000 gallon per day facility. All of the new treatment components will feature
the newest technology in nutrient removal in order to provide the highest quality
effluent to be discharged.
The current time estimate for the second plant expansion coming online is
approximately 5 years. However, this will be heavily dependent on the progress of the
EIS review. Once the discharge into the Haw River/Jordan Lake has been constructed,
the discharge into Roberson Creek will be abandoned along with the existing treatment
facility (with the exception of any components that can be of use in the expansion).
I hope this provides the necessary insight you need when postponing the
implementation of the Total Phosphorous limitations on the Roberson Creek discharge
permit. If you have any questions or need additional information, please do not
hesitate to call me at [phone].
Sincerely,
HOBBS, UPCHURCH & ASSOCIATES, P.A.

Dear Mr. Sledge-- fikPfC
This is Adam Kiker with Hobbs, Upchurch & Assoc. and we are workingwith the Town of Pittsboro as their
engineer for the WWTP upgrades/modifications/expansions. I was asked by Sam Misenheimer (manager, r/
Pittsboro) to follow up on a conversation between yourself and John Poteat (see emails below) in reardt, C�! IS
to the renewal of the Town's WWTP discharge permit.
I guess my question is relating to the nutrient loading that will be allocated to the Town for Robeson
Creek. We are currently working with the Town to obtain a much larger discharge permit either in the Haw
or in Jordan Lake (thus abandoning the Robeson Creek site). We have received verbal conformation fro
Mike Templeton (NPDES) that Pittsboro would be able to discharge around 3.8-4.0 MGD into the Haw
based on the most recent nutrient allocations and based on the latest nutrient removal technology.
This being said, we feel it would not be advisable for the Town to spend any more money than necessary W
r
on upgrades to the existing plant, even if this means operating under a Special Order by Consent until a
new plant comes online.
Could you possibly shed some light on what options the Town has in reference to their permit renewal?
We are trying to finalize a game plan for our client and we need to know our options with the Robeson
Creek discharge.

As a matter of information I had requested John Poteat to contact the State Permitting Division regarding the
renewal of the Town's WWTP Permit at DWQ. He checked Bob Sledge as noted below, who indicated that the
process has been delayed due to the potential change in nutrient removals, etc. Can you guys also follow up on
this matter as well to see where the permit renewal stands at this time? Let me know if you have any q estions,
or you can speak with John Poteat directly as ell Jl) fi

I Just got off the phone with Bob Sledge from DWQ (919-733-5083) to see when should we expect our
permit. He informed me that it's been on his desk a while and it's being held up because of basin wide
permitting. He also felt that because of the TMDL of Roberson creek, our Total N could be less than 5.0
mg/1 but that decision is not in his hands.

Well, Bob, I thought this one would be simple! (or fairly so). After speaking with
Mike and Michelle W. - it is much more complicated because of the work being done for
the Jordan lake TMDL and the complications with Senate Bill 981. Mike may need to
speak with the higher powers before we come to some conclusion. To my knowledge -
this is the first TMDL with localized impact that directly affects a point source
(just your luck, huh?). But it is classified as a minor.
Some possibilities:
Renew the permit and 1) just give them warning/reopener re. TP load for Robeson
creek, 2) give them a more stringent TP limit, but not as stringent as the TMDL would
require - just to make sure they keep on track with upgrade and relocation, 3) give
them 3 years to meet TMDL (the least favorable option because of their current
efforts to expand, relocate and install BNR) - this one may also be in conflict with
SB 981.
Anyway - bottom line - hold onto it until you hear from Mike or me. Sorry about
that.

Roberson (Robeson) Creek TMDL Final Repot
1 Introduction
Roberson (Robeson) Creek ' is currently on North Carolina's 303(d) list of impaired waters for
chlorophyll a (chl a) violations in 0.6 miles of the lower reach near its confluence with the Haw
River arm of Jordan Lake. The main stem of Roberson Creek is also on the 303(d) list for
biological impairment from a point 0.7 miles downstream of SR 2159 to upstream of the mouth.
In addition, Pittsboro Lake, located on the upper portion of Roberson Creek in the Town of
Pittsboro, is on the 303(d) list due to aquatic weeds. This report focuses on impairment related to
chl a in the most downstream portion of Roberson Creek, referred to hereafter as the Roberson
Creek Cove. The report determines sources and allowable loads of total phosphorus, which has
been identified as the factor most limiting the growth of algae as measured by chl a.
Section 303(d) of the Clean Water Act (CWA) requires states to develop a list of waters not
meeting water quality standards or which have impaired uses. This list, referred to as the 303(d)
list, is submitted biennially to the U.S. Environmental Protection Agency (EPA) for review.
The 303(d) process requires that a Total Maximum Daily Load (TMDL) be developed for each of
the waters appearing on Part I of the 303(d) list. The objective of a TMDL is to estimate
allowable pollutant loads and allocate to known sources so that actions may be taken to restore
the water to its intended uses (USEPA, 1991). Generally, the primary components of a TMDL, as
identified by EPA (1991, 2000a) and the Federal Advisory Committee (FACA, 1998) are as
follows:
Target identification or selection of pollutant(s) and end-point(s) for consideration. The pollutant
and end -point are generally associated with measurable water quality related characteristics that
indicate compliance with water quality standards. North Carolina indicates known pollutants on
the 303(d) list.
There are several spellings of this waterbody. A 1930's USDA SCS soil map refers to the creek
as Robeson Creek as do the NC Department of Transportation road signs marking access points to
the creek. However, USGS and DWQ have spelled the creek as Roberson Creek. The spelling
used by USGS will be used in the main body of the report.

Roberson (Robeson) Creek TMDL Final Report
Source assessment. All sources that contribute to the impairment should be identified and loads
quantified, where sufficient data exist.
Reduction target. Estimation or level of pollutant reduction needed to achieve water quality goal.
The level of pollution should be characterized for the waterbody, highlighting how current
conditions deviate from the target end -point. Generally, this component is identified through
water quality modeling.
Allocation of pollutant loads. Allocating pollutant control responsibility to the sources of
impairment. The wasteload allocation portion of the TMDL accounts for the loads associated
with existing and future point sources. Similarly, the load allocation portion of the TMDL
accounts for the loads associated with existing and future non -point sources, stormwater, and
natural background.
Margin of Safety. The margin of safety addresses uncertainties associated with pollutant loads,
modeling techniques, and data collection. Per EPA (2000a), the margin of safety may be
expressed explicitly as unallocated assimilative capacity or implicitly due to conservative
assumptions.
Seasonal variation. The TMDL should consider seasonal variation in the pollutant loads and
end -point. Variability can arise due to stream flows, temperatures, and exceptional events (e.g.,
droughts, hurricanes).
Critical Conditions. Critical conditions indicate the combination of environmental factors that
result in just meeting the water quality criterion and have an acceptably low frequency of
occurrence.
Section 303(d) of the CWA and the Water Quality Planning and Management regulation
(USEPA, 2000a) require EPA to review all TMDLs for approval or disapproval. Once EPA
approves a TMDL, then the waterbody may be moved to Category 4a of the Integrated Report.
Waterbodies remain in Category 4a until compliance with water quality standards is achieved.
Where conditions are not appropriate for the development of a TMDL, management strategies
may still result in the restoration of water quality.

Roberson (Robeson) Creek TMDL Final Report
The goal of the TMDL program is to restore designated uses to water bodies. Thus, the
implementation of nutrient controls throughout the watershed will be necessary to restore uses in
the Roberson Creek Cove. Although an implementation plan is not included as part of this
TMDL, reduction strategies for point and nonpoint sources will be needed. The involvement of
local governments and agencies will be critical in order to develop implementation plans and
reduction strategies. Development of an implementation plan will begin during public review of
the TMDL. The NCSU Water Quality Group will be developing general and site -specific
implementation plans.
1.1 Watershed Description
Roberson Creek flows in an easterly direction 10.9 miles from its origins southwest of the Town
of Pittsboro to its mouth at the Haw River arm of Jordan Lake (Figure 1.1). Located entirely
within the Pittsboro town limits and its extra -territorial jurisdiction, the 28.6-mi 2, piedmont
watershed is approximately 73% forested, 9% agricultural, and 16% urban (NCSU Water Quality
Group 2002; Figure 1.2). Part of the upper watershed consists of residential, commercial, and
industrial development surrounding the Town of Pittsboro. The area outside of the corporate
limits of Pittsboro consists primarily of low density residential development, agriculture, and
forestland. The Pittsboro wastewater treatment plant (WWTP; NPDES permit #NC0020354)
discharges into Roberson Creek 7.0 miles upstream from Jordan Lake. The lower watershed,
from the Pittsboro WWTP to Jordan Lake consists mostly of undeveloped forestland, low density
residential development, pasture and hayfields.
The Roberson Creek watershed is located within the Carolina Slate Belt, which consists of
predominately metavolcanic and metigneous rocks. This geology typically yields low base flows
compared to other hydrologic areas (Giese and Mason 1993). Roberson Creek descends
approximately 230 feet from its headwaters to Jordan Lake (10.9 miles), with approximately 100
feet of descent in the last three miles. This gradient is typical of streams in the Haw River basin.
Surface water classifications are designations applied to surface water bodies that define the best
uses to be protected within these waters (for example swimming, fishing, drinking water supply)
and carry with them an associated set of water quality standards to protect those uses. Roberson

Roberson (Robeson) Creek TMDL Final Report
Creek is classified as a water supply watershed (WS-IV), nutrient sensitive (NSW), and a class C
waterbody. The waters are protected for drinking water supply, 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.

4.5 Waste Load Allocation
.i." -073
Pittsboro WWTP was the only4oint source in Roberson Creek watershed during the study period.
The plant contributed about 503 kg of TP during summer (Table 3.6). As per the discussion in §
4.1 above, reduction of TP required to meet the chl a standard at the Roberson Creek Cove with a
margin of safety is 71 %. Therefore, reductions of TP required from the WWTP were estimated to
be 357 kg for summer.
4.6 Load Allocation
Non -point sources that contributed TP in the Roberson Creek watershed were urban lands,
forested lands, and pasture/hay lands on an annual basis. There are no permitted stormwater
sources (MS4) in this watershed. Urban lands were the only non -point sources that contributed
153 kg of TP during summer season (Table 3.7). Reduction required from the urban lands to meet
the chl a in the cove was, therefore, 106 kg. Overall, the reduction of TP required to meet the chl
a standard at the Roberson Creek cove was 464 kg during the summer season (April — October).

Roberson (Robeson) Creek TMDL
5 Implementation Plan
Final Report
The TMDL analysis was performed using the best data available to specify the nutrient reductions
necessary to achieve water quality criteria: the chl a target in this lower portion of Roberson
Creek. The intent of meeting the criteria is to support the designated use classifications in the
watershed. The decision to focus on P was based on the assumption that P will ultimately control
growth in the cove and reductions in P will drive the cove to an increasingly P limited state (by
increasing the N:P ratio). As a practical matter, some reductions of N will likely accompany P
reductions. This is desirable because although N is not the primary limiting nutrient during most
of time, loading of N does contribute to algal growth in the cove. Furthermore, downstream
waters such as Jordan Lake may be affected by N contribution from this watershed. Therefore, an
increase in N loading is not be recommended.
The TMDL requires reductions from urban sources of P and Pittsboro's wastewater treatment
plant. In addition to reductions form existing urban sources, future growth in urban land uses
within the watershed should be accompanied by nutrient control measures.
This TMDL targets an algal growing season due to timing of algal blooms and residence time in
the cove. The reductions will protect Roberson Creek and its intended uses during all times of the
year. Nonetheless, nutrient controls during winter are suggested for two reasons. First,
downstream waters (Jordan Lake) are affected by nutrients transported from this watershed.
Second, there may be some stored P within the watershed derived from the winter that may be
transported to the cove during summer.
A detailed implementation plan is not included in this TMDL. The involvement of local
governments and agencies will be needed in order to develop the implementation plan. During
2002, the NCSU Water Quality Group received a EPA Section 319 grant to perform a watershed
assessment of the Roberson Creek watershed. Part of the project will involve identification of
areas for targeting of best management practices (BMP) within the watershed. The Water Quality
Group will be developing general and site -specific implementation plans for Roberson Creek.

Roberson (Robeson) Creek TMDL
6 Stream Monitoring
Final Report
Monitoring will continue on a monthly interval at the ambient monitoring site in the Roberson
Creek Cove. The continued monitoring of nutrient and chl a concentrations will allow for the
evaluation of progress towards the goal of achieving water quality standards and intended best
uses.
7 Future Efforts
Overall, the reduction of TP required to meet the chl a standard at the Roberson Creek cove was
464 kg during the summer season. Nutrient loading will vary year-to-year based on changes in
flow regime. The allowable TP load to the Roberson Creek Cove is based on an identified critical
condition for nutrient enrichment: a dry algal growing season. Dry hydrologic conditions in
Roberson Creek Cove would be expected to maximize residence time and nutrient retention,
thereby promoting algal growth (Wetzel 2001). Further monitoring and modeling may be
desirable in the future to confirm these assumptions. Future work may include an enhanced
characterization of the relationship between flow and nutrient concentrations across a range of
hydrologic conditions. Likewise, an analysis of eutrophication response during wetter years may
be useful.
8 Public Participation

Town of Pittsboro - Land application/reuse/education project
NPDES No. NC0020354
This request from the Town of Pittsboro is to divert approximately 65,000 gpd of treated
wastewater from the Pittsboro wastewater treatment plant to Central Carolina
Community College. The treatment plant currently discharges to Robeson Creek, which
is (303 d) listed as impaired (chlorophyll a and biological integrity).
From the perspective of the NPDES Unit, this request could benefit water quality by
diverting a portion of the wastewater load from Robeson Creek. The NPDES Unit would
have no objection to this request (either the land application site or the constructed
wetlands), as long as the requirements set forth by the Aquifer Protection Section were
met. The added benefit to this project would be to provide an educational source to the
Community College.

Subject: Proposed NPDES Permitting Actions for 2006 Permit Renewals
Cape Fear River Basin (Raleigh Regional Office)
On 10/31/2005, NPDES staff (Gil Vinzani, Vanessa Manuel, Tom Belnick) met with Raleigh Region
Surface Water Protection staff (Ken Schuster, Shannon Langley, Chris Wu, Judy Garrett, Jennie Atkins,
Mack Wiggins, Barry Herzberg), to consider facility compliance in drafting NPDES permit renewals for
facilities located in the Cape Fear River Basin. A short list of 25 facilities were identified within the
RRO which exceeded subjective compliance thresholds, and the need for possible permitting actions for
these facilities were discussed. A summary of these discussions and recommended actions are presented
below, and included with each permit file. Assigned permit writers should incorporate recommended
actions or conduct followup with RRO and/or NPDES staff as necessary. Please see NPDES staff listed
above with any questions.
1) NC0020354 (Pittsboro WWTP; permit assigned to Bob S)- Considering diversion of some flow,
looking to eventually move discharge to Haw River. No action necessary.
2) NC0023442 (Wood Resources/Moncure Plywood; permit assigned to Frances C)- Rarely discharges,
as more satellite bathrooms added. May need TRC limit. No action necessary.
3) NC0025241 (OWASA Mason Farm; permit assigned to Jackie N)- Currently undergoing upgrade
(switch to UV disinfection, adding deep bed filters) with construction to be completed by Summer 2007.
No action necessary.
4) NC0025305 (UNC-CH Cogen Facility; permit assigned to Bob S)- facility doesn't currently
discharge, as all wastewater goes to OWASA. They might want to maintain permit as backup. No
action necessary.
