A (2). CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY) - 1.2 MGD
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 84%.
The permit holder shall perform at a minimum, guarterlmonitoring 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
January, April, July, and October. 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 Branch
1621 Mail Service Center
Raleigh, North Carolina 2.7699-1621
Completed Aquatic Toxicity Test Forms shall be' filed with the Environmental Sciences Branch no
later than 30 days after the end of the reporting period for which the report is made.
Testy 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 permittee 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 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 the initial monitoring.

BACKGROUND
The Town of Troy WWTP has been operating at 0.84 MGD flow with a phased flow of 1.2
MGD. In Dec 2003, they submitted an Engineer's Certificate for an upgrade to the disinfection
unit, enabling them to operate at their higher permitted flow of 1.2 MGD. The Division did not
receive this certificate and therefore the permit renewal was drafted at the 0.84 MGD flow.
Within the notice period, the Division was notified of the change and the permit has been
modified to reflect the higher flow.
VERIFICATION OF EXISTING CONDITIONS AND DATA REVIEW
This facility discharges to subbasin 03-07-15 in Denson's Creek, classified C waters. The
receiving stream is not listed on the 2003 303(d) list as impaired, and the basin plan does not
outline any special management strategy for this creek. Troy is not a member of the Yadkin -Pee
Dee River Coalition.

Table 1. NCO028916 Conventional Data (January 2002-December 2003)
This facility also collects data for total nitrogen, total phosphorus, and ammonia nitrogen (NH3-
N). It consistently meets its ammonia limits of 2mg/1 (summer) and 4 mg/l (winter).
A review of the metals (from both the DMRs and Pretreatment data) and toxicants was also
performed. With the exception of total residual chlorine (TRC), these are discussed in the
Nc:t Shect
NPDES NC002. 916 Rcnet-al
Pw2lc 1

Reasonable Potential Analysis section. TRC levels from January 2002-December 2003 varied
from 7.1 µg/L to 705.4 µg/L. The current permit does not have a TRC limit. A TRC limit will
be included with this renewal.
Correspondence Files (2002-2003)
The Fayetteville Regional Office (FRO) conducted several site visits during this permit term to
evaluate compliance. The facility has demonstrated consistent compliance in meeting its permit
limits and has received no NOV's in the past two years except for one toxicity failure in July
2003.
Toxicity Testing
Current requirement: Chronic P/F @ 79% (at 0.84 MGD); 84% (at 1.2 MGD).
Recommended requirement: Chronic P/F @ 84%
The facility has been in compliance with its toxicity limit with the exception of two failures, one
in October of 2001 and the other in July of 2003. In both of these instances, the test of the
following month was passed.
PERMITTING STRATEGY
Waste Load Allocation (WLA)
The Division prepared the last WLA for the previous permit renewal. The previous and current
effluent limits were based on guidelines and water quality standards. The Division has judged
previous parameters and limits to be appropriate for renewal with some exceptions. Changes to
toxicant monitoring are discussed in the Reasonable Potential Analysis section. Weekly average
ammonia limits based on a 3:1 ratio with the monthly average will be implemented in this
permit. This is a new statewide policy that resulted from EPA requirements. The resulting
summer weekly average limit will be 6.0 mg/L and the winter limit will be 12.0 mg/L.
In addition, an annual pollutant scan will be added such that the Permittee can collect the
necessary data required by EPA Form 2A throughout the permit term. This condition is now
standard on all municipal permits with complex wastewater in North Carolina.
Reasonable Potential Analysis (RPA)
The Division conducted EPA -recommended analyses to determine the reasonable potential for
toxicants to be discharged by this facility, based on DMR and pretreatment data from January
2002-November 2003. Calculations included parameters listed in the previous permit and pre-
treatment documents to include: arsenic, copper, chlorides, zinc, chromium, lead, mercury,
molybdenum, nickel, and selenium. Results suggest no reasonable potential for the facility to
discharge arsenic at levels greater than the allowable concentration. Copper, chloride, and zinc
were predicted at concentrations higher than the allowable; however these three are action level
parameters and limits are not commonly given unless they are triggered under the Action Level
Policy. These will continue to be monitored, but not limited in the renewal. Cadmium, currently
monitored through the NPDES permit, was not detected once in the past two years and will be
eliminated from the NPDES monitoring requirements. The facility will still be required to
monitor for cadmium through the Pretreatment Short Term Monitoring Plan (STMP). Cyanide,
which is limited in the current permit, was not detected once in the past two years; the
limit/monitoring requirement will be deleted in the renewal. Cyanide is not monitored in the
STMP. Data from all other toxicants currently monitored through the STMP was examined and
showed no reasonable potential to violate water quality standards. These will continue to be
monitored through the STMP.
SUMMARY OF PROPOSED CHANGES
In keeping with Division policies, the following will be incorporated into the permit:
NI -TES NC 02S916 I2e:r cwal
],age 2

• New weekly average ammonia limits (both summer and winter)
• Annual pollutant scan
• Elimination of the cadmium monitoring requirement
• Elimination of the cyanide limit and monitoring
• Addition of TRC limit; 22µg/1 for 0.84 flow and 20µg/l for 1.2 MGD flow

Marshall,
Thanks for responding so quickly. Form 2A was signed 08-01-03 (received
here 9-12-03) and the expanded effluent testing data included 3 samples.
I am attaching the fact sheet, rpa, and draft permit. Form 2A will have
to be sent to you via snail mail. I'll send it out right now!! (I'll
include a hardcopy of the fact sheet and draft with it.)
Sorry for the hiccup on this one; hopefully, we can still issue it
promptly. Thanks again. Let me know if you need anything else.

Hyatt,
Dave wanted me to e-mail you about a draft that I sent to notice in
April. It was drafted as a phased permit. One flow was 0.84 MGD and one
was 1.2 MGD (after upgrading and sending in an Engineer's Certification
etc.)
At the time of drafting, all indications were that they were operating
at the 0.84 flow, so I didn't send it to EPA for review. Now it has
come to my attention that they did upgrade and send in the paperwork in
January to go to the higher flow. (We didn't see this information in
writing until today.)
I've attached the electronic copies of the fact sheet (in case you have
specific questions) as it was written in April. Obviously, a few
changes are necessary and would be made. My question is: Given the
situation, what is your recommendation and what do you need from me?
I will hold onto this until I hear from you.
Thanks,
Dawn Jeffries

Charles R. Fullwood, Executive Director
MEMORANDUM
TO: Dawn Jefferies, NPDES Unit
Di ision of Water Quality
FROM: Saft�nt Region Coordinator
Habitat Conservation Program
DATE: 14 May 2004
SUBJECT: Proposed Permit Renewal for Town of Troy, Wastewater Treatment Plant,
Montgomery County, NPDES Permit No. NC0028916
Biologists with the North Carolina Wildlife Resources Commission have reviewed the
subject application for impacts to fish and wildlife. Our comments are provided in accordance
with provisions of the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C.
661-667d), and the North Carolina General Statutes (G.S. 113-131 et seq.).
The Town of Troy has applied for renewal of its NPDES permit to discharge treated
wastewater into Denson's Creek in the Yadkin -Pee Dee River Basin. There are records for the
federal species of concern and state endangered Carolina creekshell (Villosa vaughaniana),
brook floater (Alamidonta varicosa), Savannah lilliput (Toxolasma pullis) and yellow
lampmussel (Lampsilis cariosa); the federal species of concern and state special concern
Carolina darter (Etheostoma collis); the state threatened triangle floater (Alasmidonta unduaaua),
creeper (Strophitus undulatus), and Carolina fatmucket (Lampsilis radiata conspicua); the state
special concern notched rainbow (Villosa constricta) and the state significantly rare Eastern
creekshell (Villosa delumbris) in Denson's Creek and Little River watersheds. From the
information provided in the public notice, it appears that ammonia nitrogen and total residual
chlorine are water quality limited in Denson's Creek.
Chlorine is acutely toxic to aquatic organisms and forms secondary compounds that are
also detrimental to aquatic life. Additionally, freshwater mussels are among the most sensitive
aquatic organisms tested for impacts from ammonia, and ammonia may be a significant limiting
factor for unionids (Augspurger et al., 2003). Augspurger et al. (2003) found that ammonia
concentrations which may be protective of freshwater mussels range from 0.3 to 1.0 mg/L total
ammonia as N at pH 8.

Town of Troy, Wastewater Treatment Plant
NPDES No. NCO028916
We recommend that the following conditions be incorporated into the permit to reduce
impacts to fish and wildlife resources.
1. We suggest that the chlorine systems be replaced by ultraviolet light or ozone systems.
Utilization of these techniques would provide an additional benefit of removing a
hazardous material from the workplace.
2. We recommend a reevaluation of ammonia limits based on the research discussed above
and readjusting the limits. Please contact Tom Augspurger with the U.S. Fish and
Wildlife Service at [phone] for additional information.
3. If not already in plane, we suggest the installation of a stand-by power system
Thank you for the opportunity to provide input during the planning stages for this project.
If we can be of further assistance, please contact our office at [phone].

BACKGROUND
The Town of Troy WWTP is currently permitted for 0.84 MGD flow and for a flow of 1.2 MGD
once the disinfection unit has been upgraded and an Engineer's Certificate has been submitted.
As the Division has not yet received an Engineer Certificate for the upgrade, the facility is still
operating under the 0.84 MGD flow limit.
VERIFICATION OF EXISTING CONDITIONS AND DATA REVIEW
This facility discharges to subbasin 03-07-15 in Denson's Creek, classified C waters. The
receiving stream is not listed on the 2003 303(d) list as impaired, and the basin plan does not
outline any special management strategy for this creek. Troy is not a member of the Yadkin -Pee
Dee River Coalition.
DMR Data (2002-2003)

Table 1. NCO028916 Conventional Data (January 2002-December 2003)
This facility also collects data for total nitrogen, total phosphorus, and ammonia nitrogen (NH;-
N). It consistently meets its ammonia limits of 2mg/l (summer) and 4 mg/1 (winter).
A review of the metals (from both the DMRs and Pretreatment data) and toxicants was also
performed. With the exception of total residual chlorine (TRC), these are discussed in the
Reasonable Potential Analysis section. TRC levels from January 2002-December 2003 varied

from 7.1 µg/L to 705.4 µg/L. The current permit does not have a TRC limit. A TRC limit will
be included with this renewal.
Correspondence Files (2002-2003)
The Fayetteville Regional Office (FRO) conducted several site visits during this permit term to
evaluate compliance. The facility has demonstrated consistent compliance in meeting its permit
limits and has received no NOV's in the past two years except for one for the toxicity failure in
July 2003.
Toxicity Testing
Current requirement: Chronic P/F C 79% (at 0.84 MGD); 84% (at 1.2 MGD). No changes
recommended.
The facility has been in compliance with its toxicity limit with the exception of two failures, one
in October of 2001 and the other in July of 2003. In both of these instances, the test of the
following month was passed.
PERMITTING STRATEGY
Waste Load Allocation (WLA)
The Division prepared the last WLA for the previous permit renewal. The previous and current
effluent limits were based on guidelines and water quality standards. The Division has judged
previous parameters and limits to be appropriate for renewal with some exceptions. Changes to
toxicant monitoring are discussed in the Reasonable Potential Analysis section. Weekly average
ammonia limits based on a 3:1 ratio with the monthly average will be implemented in this
permit. This is a new statewide policy that resulted from EPA requirements. The resulting
summer weekly average limit will be 6.0 mg/L and the winter limit will be 12.0 mg/L.
In addition, an annual pollutant scan will be added such that the Permittee can collect the
necessary data required by EPA Form 2A throughout the permit term. This condition is now
standard on all municipal permits with complex wastewater in North Carolina.
Reasonable Potential Analysis (RPA)
The Division conducted EPA -recommended analyses to determine the reasonable potential for
toxicants to be discharged by this facility, based on DMR and pretreatment data from January
2002-November 2003. Calculations included parameters listed in the previous permit and pre-
treatment documents to include: arsenic, copper, chlorides, zinc, chromium, lead, mercury,
molybdenum, nickel, and selenium. Results suggest no reasonable potential for the facility to
discharge arsenic at levels greater than the allowable concentration. Copper, chloride, and zinc
were predicted at concentrations higher than the allowable; however these three are action level
parameters and limits are not commonly given unless they are triggered under the Action Level
Policy. These will continue to be monitored, but not limited in the renewal. Cadmium, currently
monitored through the NPDES permit, was not detected once in the past two years and will be
eliminated from the NPDES monitoring requirements. The facility will still be required to
monitor for cadmium through the Pretreatment Short Term Monitoring Plan (STMP). Cyanide,
which is limited in the current permit, was not detected once in the past two years; the
limit/monitoring requirement will be deleted in the renewal. Cyanide is not monitored in the
STMP. Data from all other toxicants currently monitored through the STMP was examined and
showed no reasonable potential to violate water quality standards. These will continue to be
monitored through the STMP.
SUMMARY OF PROPOSED CHANGES
In keeping with Division policies, the following will be incorporated into the permit:
• New weekly average ammonia limits (both summer and winter)

Narrative for NPDES PERMIT APPLICATION ITEM B.3
TOWN OF TROY
Permit Number NCO028916
Facility Description
The Town of Troy has an activated sludge/ aerobic digestion wastewater treatment plant. The
plant has dual bar screens. An old style bar screen with approximately 1 ''/z" openings is mounted
in front of a "Rotomat" fine screen drum bar screen. The Rotomat is designed for 1.5 MGD. The
grit handling system is a S & L Pista Grit system with capacity to 1.2 MGD. The influent pump
station is a Gorman & Rupp T6 suction lift pump station sized for 1.2 MGD. The plant has dual
oxidation ditches with two dual speed brush rotors in each ditch. The ditches are each sized for .6
MGD with 24 hours of detention time. The plant has two peripheral feed clarifiers each sized to
handle .6 MGD. Each clarifier's tank capacity is approximately 94,000 gallons. The return sludge
pump station has two Flygt submersible solids handling pumps with each pump sized for 1.2
MGD. The waste sludge holding tank is aerated with coarse bubble diffusers using two Aerison
positive displacement blowers. The tank has approximately 97,000 gallons of capacity. The waste
sludge pump station is sized to waste at approximately 300 gpm. The waste sludge holding tank
will store approximately 1.2MG of decanted sludge. The waste sludge is land applied. The plant's
disinfection system is Ultra -Violet light. New SCADA equipment utilizing radio communications
has just been installed at the plant. This equipment will monitor the status of the influent pump
station, the oxidation ditch rotors, the status of the sludge sweep arm and the sludge level in each
clarifier and maintain influent and effluent flow records.
