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, ua artery 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. If reporting pass/fail results using the parameter code TGP3B, DWQ
Form AT-1(original) is sent to the below address. If reporting Chronic Value results using the parameter code THP313, DWQ

Habitat Conservation Program ""
DATE: 12 August 2008
SUBJECT: Proposed Permit Renewal for Town of Fuquay-Farina, Terrible Creek WWTP, Wake
County, NPDES Permit No. NC0066516
Biologists with the North Carolina Wildlife Resources Commission have reviewed the subject
document. Our comments are provided in accordance with provisions of the Clean Water Act of 1977 (as
amended), Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d), North
Carolina General Statutes (G.S. 113-131 et seq.), and North Carolina Administrative Code 15A NCAC
10I.0102.
The Town of Fuquay-Farina has applied for a renewal of its NPDES permit to discharge treated
wastewater into Terrible Creek. The Public Notice indicates BOD5, ammonia nitrogen, cyanide, total
nitrogen and total phosphorus are water quality limited.
Terrible Creek is a tributary to Middle Creek in the Neuse River basin. There are records for the
federal and state endangered dwarf wedgemussel (Alasmidonta heterodon); the federal species of concern
and state endangered Atlantic pigtoe (Fusconaia masoni); the federal species of concern and state
significantly rare pinewoods shiner (Lythrurus matutinus); the state threatened creeper (Strophitus
undulatus), Eastern lampmussel (Lampsilis radiata), triangle floater (Alasmidonta undulata) and least
brook lamprey (Lampetra aepyptera) in Middle Creek.
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.
We are especially concerned about impacts to dwarf wedgemussel and other listed species in
Middle Creek. Therefore, we offer the following recommendations to reduce impacts to aquatic
resources.

If the WWTP uses chlorine systems for disinfection, these should be replaced by ultraviolet light
or ozone systems. Chlorine is acutely toxic to aquatic organisms and can form secondary
compounds that are detrimental to aquatic life. Valenti (2006) concluded the impact of long term
exposure to low doses of chlorine may impact juvenile mussels and reduce the chance of them
being recruited to the reproducing population.
2. If current ammonia limits exceed those listed above, we recommend a re-evaluation of the
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 place, we suggest the installation of a stand-by power system.
Thank you for the opportunity to comment on this permit renewal. If we can be of fii Cher
assistance, please contact our office at [phone].

Proposed
I. Changes Incorporated into Permit Renewal
o The facility reported a cyanide value of 38 through its STMP, therefore a cyanide limit
will be added to the permit (at all tiers).
o The TN yearly load limit will increase from 67,5801bs to 68,4891bs as a result of
supplemental allocation from Southside MHP (formerly NC0030724) and Wake Technical
Institute (formerly NC0025631).
II. Summary
The Terrible Creek WWTP is one of two plants serving the Town of Fuquay-Varina. Terrible
Creek WWTP currently has a permitted flow of 1.0 MGD and has three additional permitted tiers
for expansions to 2, 4, and 6 MGD. The existing plant is a Grade III biological facility achieving
nutrient removal. Class B sludge from the plant is land applied by contract. Because of the small
number of SIUs served by the plant (only two, comprising 8% of the total flow), the pretreatment
monitoring program is modified such that monitoring only occurs on a quarterly basis. The
Town will continue to monitor in accordance with the established Short Term Monitoring Plan
(STMP).
Terrible Creek is a C-NSW class stream in the Neuse River Basin. The stream is not on the draft
2008 303(d) list. Although Terrible Creek is not itself listed on the 303(d) list, the Neuse River
estuary to which it drains is on the 303(d) list for chlorophyll -a. As a result, the upstream waters
of the Neuse River Basin have been given the nutrient sensitive (NSW) additional classification
and the Town, of Fuquay-Varina must adhere to the nutrient limitations set out by,basin plans
and the Nitrogen TMDL.
Nitrogen
The Environmental Management Commission adopted Nutrient Management Strategy rules in
December 1997, classifying the entire Neuse River Basin as Nutrient Sensitive Waters. The point

NPDES Permit Fact Sheet — 07/ 14/08

Terrible Creek WWTP
NCO066516
source rule (T15A NCAC 2B .0234) sets Total Nitrogen (TN) discharge limits for all point source
dischargers larger than 0.5 MGD.
The rule also allows dischargers to forma group compliance association and work together to
reduce nitrogen; this option allows the association members added flexibility in controlling
nitrogen discharges. At the same time, the association is subject to a group NPDES permit
ensuring that the association and its individual members are accountable if they exceed the
applicable nitrogen limits.
Under .the rule, there are three types of TN limit in the Neuse:
1. the individual limits in the dischargers' individual permits,
2. the aggregate limit in an association's group NPDES permit, and
3. the individual allocations/limits for each Association member, also in that association
permit.
A discharger may be subject to the first type of limit, or to the second and third, but never to all
three at the same time. The discharger is first subject to the TN limit (if any) in its individual
NPDES permit. If becomes a co-permittee to a compliance association's group NPDES permit, it is
then governed by the TN limits in that permit. If the association complies with its group TN limit
in a given year, all members are deemed to be in compliance with their individual allocations/
limits in the group permit. If the association exceeds its limit, the members then become subject to
their individual allocations/ limits as well.
Regardless of which permit governs a TN discharge, allocations/ limits will likely change over
time as the dischargers purchase, sell, trade, lease, or otherwise transfer nitrogen allocations. The
Division will modify the affected permits as necessary to ensure that the limits are kept up to
date and reflect any such transactions.
The permit includes nutrient limits consistent with the Nutrient Management Strategy rule
(T15A NCAC 213.0234).
Under the new rule, the Town of Fuquay Varina receives a TN Load limit of 68,489 lb/yr, a
calendar year limit.
In the event the Town joins a compliance association, it will be deemed to be in compliance with
the TN limit in this permit, and its TN discharge will be governed instead by the Association's
group NPDES permit, issued December 30, 2002.
The City's 2.0 mg/L Total Phosphorus limit is carried forward in the new permit as a quarterly
average limit to conform with the new rule.
III. Compliance Summary
DMR Data Reviezv
The facility's monthly average DMR data was reviewed for the period of January 2005 - March
2008. A summary of that data is reported in the following table. The facility is currently
discharging at an average of 50% capacity, with maximum monthly average flows at 60%
capacity. The facility has a tiered permit with limits at 1,2,4, and 6 MGD.

2005: 10,795 LBS
2006: 15, 935 LBS
2007: 10,265 LBS
The TN yearly load limit will increase from 67,5801bs to 68,4891bs as a result of supplemental
allocation from Southside MHP (formerly NC0030724) and Wake Technical Institute (formerly
NC0025631).
Instream Data Review
The Terrible Creek WWTP is a member of the Lower Neuse Basin Association (LNBA). There is
an LNBA monitoring station 4 miles downstream of the discharge, after the confluence of
Terrible Creek and Middle Creek. This data was reviewed to see if there was a correlation
between some of the high BOD and fecal values reported at the plant and instream data. There
were several instances when instream fecal coliform data was reported as TNTC (too numerous
to count), however there appeared to be no correlation between those values and plant data.
RPA Analysis
A reasonable potential analysis was performed for zinc, which is currently monitored in the
NPDES permit. Based on data from March 2006- March 2008, zinc effluent levels did show
reasonable potential to cause an exceedance of the action level standard. Since this is an action
level parameter, the facility will not receive a limit at this time. Monthly monitoring will remain
in the permit.
Based on the results of the PPAs and STMP data, maximum predicted copper and cyanide values
levels were also above allowable levels. However the high -predicted copper level was due to a
calculated variance based on a change in detection levels (from 2 µg/L to 5 µg/L). Therefore
copper will continue to be monitored through the facilities STMP. The facility reported a cyanide
value of 38 through its STMP, therefore a cyanide limit will be added to the permit.
Other pollutants monitored through the STMP were arsenic, cadmium, chromium, lead, mercury,
molybdenum, nickel, silver and selenium. Only nickel was above detectable levels. None of
these parameters (including nickel) showed reasonable potential to cause an exceedance of water
quality standards.
WET Test Results
The Terrible Creek WWTP has a chronic whole effluent toxicity testing requirement at 90%
effluent concentration. The facility has passes 17/17 tests administered since March 2004.
Correspondence File Review/Compliance History
The Terrible Creek WWTP is currently on EPA's quarterly Watchlist for April 2008. The facility
appeared on the watchlist because they had 27 limit violations from Jan06-Dec07. Of these, 5

NPDES Permit Fact Sheet - 07/ 14/08

NC0066516
resulted from Tropical Storm Alberto in June 06. Those exceedances (the only ones for June 06)
were considered as resulting from an Act of God, and were not treated as violations for penalty
consideration. Excluding the violations from this storm event, the facility has 22 valid limit
violations and therefore does not meet the Watch List criteria. The remaining violations were
attributed to the plant's high solids inventory. DWQ held show cause meet on 6/19/2007, and
facility submitted plan to reduce high solids. A state inspection conducted March 4, 2008,
revealed the solids inventory level has been reduced.
Since the Division and the facility has taken measures to address these operational challenges, a
Facilities Management Plan will not be required through the NPDES permit at this time. This
facility's compliance history will be reevaluated during the next permit cycle to determine
whether or not additional measures should be implemented in the permit.
