Subject: NPDES Permit Issuance
Permit NCO026689
Denton WWTP
Davidson County
Dear Mr. Isenhour:
Dee Freeman
Secretary
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 October 17, 2007 for as subsequently
amended.)
The final permit authorizes the Town of Denton to discharge wastewater from the Denton WWTP to
Lick Creek, a class WS-IV water in the Yadkin -Pee Dee River Basin. The permit includes discharge
limitations/ or monitoring for flow, BODS, ammonia nitrogen, total suspended solids (TSS), dissolved
oxygen, total residual chlorine, fecal coliform, mercury, copper and zinc.
Lick Creek is listed as an impaired stream on North Carolina's 303 (d) list. Currently, the stream does not
meet all water quality standards. If the limitations in the current permits for facilities discharging to Lick
Creek do not result in improved water quality, removal of discharges to Lick Creek may be necessary for the
health of the stream.
Although the Division believes agriculture and other unknown sources are the main causes of degradation
to Lick Creek, we will continue to monitor compliance at your facility. If noncompliance with your permit's
effluent limits is shown to be a direct cause of stream degradation, the Division will recommend removal of
your facility's discharge.
Part III of your. permit requires you to "continually evaluate all wastewater disposal alternatives and
pursue the most environmentally sound alternative of the reasonably cost effective alternatives" to surface
water discharge. Such an evaluation may help you find an alternative to surface water discharge that is more
appropriate for your facility.

Letter to Mr Isenhour

The following procedure has been implemented by DWQ: Total residual chlorine (TRC) compliance
level changed to 50 ug/1 Effective March 1, 2008, the Division received EPA approval to allow a 50ug/l
TRC compliance level. This change is due to analytical difficulties with TRC measurements. Facilities will
still be required to report actual results on their monthly discharge monitoring report (DMR) submittals,
but for compliance purposes, all TRC values below 50 ug/1 will be treated as zero. Additional information
has been added to a footnote regarding this change on the effluent limitations page.
The following modifications included in the draft permit of July 29, 2009 remain in the final permit.
• The effluent limit for total nickel has been removed from the permit. The results of a
reasonable potential analysis on submitted data indicated that there would be no
exceedence of the water quality standard. It is recommended that total nickel be monitored
in the pretreatment modified monitoring program.
• A weekly average limit for total mercury of 0.012 ug/1 has been added to the permit. A
reasonable potential analysis indicated that the water quality standard for mercury could
be violated in the receiving stream.
• There has been some modification of the treatment plant components on the supplement to
permit cover sheet.
• Please note that there have been minor language changes and the addition of a new
paragraph regarding data submittal in special condition A.2. Chronic Toxicity permit limit.
(The new paragraph is located second from the end of the condition).
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 a demand is made, this permit
shall be final and binding.
Please take notice that this permit is not transferable. The Division may require modification 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, Coastal Area Management Act, or any other Federal or Local governmental permits may be
required.
If you have any questions or need additional information, please contact Ms. Jacquelyn Nowell at

SUPPLEMENT TO EFFLUENT LIMITATIONS '
AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A(2). CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia
dubia at an effluent concentration of 90 h.
The permit holder shall perform at a minimum, quarterh monitoring using test procedures outlined in the "North Carolina
Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North Carolina Phase
11 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 11 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 Il Chronic Whole Effluent Toxicity Test Procedure"
(Revised -February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition wilt 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:

1.0 Proposed Changes Incorporated into Permit Renewal
• Add daily maximum mercury limit of 12 ng/1 (0.012 ug/1) with 2/month monitoring
frequency, based on reasonable potential to cause an exceedance of the water quality standard
• Remove weekly average and daily maximum nickel limits because of no reasonable potential
to cause an exceedance of the water quality standard
• Modification and addition of wastewater treatment components added to the supplement to
cover sheet.
2.0 Summary
The Town of Denton currently has a design capacity of 0.8 MGD and continues its
discharge to Lick Creek. The facility has tertiary limits of 5/2/6 (summer) and 10/4/6 (winter)
with monitoring for fecal coliform, TRC, temperature, TN and TP, mercury, copper, nickel and
zinc. The Denton WWTP discharges into Lick Creek, which is listed on the 2006 303d list with
impairment for aquatic life with low dissolved oxygen. Potential sources are agriculture and
other unknown sources. The 2008 Yadkin Basinwide Plan notes that Lick Creek is impaired for
DO and impacted by nutrient inputs from the upstream NPDES WWTP.
Denton WWTP has two non -categorical SIUs. Century Hosing (0.0243 MGD) and
Surratt Hosiery Mills (.0043 MGD). It is recommended that the modified pretreatment program
with Short Term Monitoring Plan be continued during the next permitting cycle.

3.0 Compliance Summary
Town of Denton WWTP
NC0026689
Correspondence File Review/Compliance History
The Denton WWTP appears to have had consistent problems in the last three years in
meeting BODS, TRC, NH3, fecal coliform and chronic toxicity limits. In the renewal application,
the facility asked for some relaxation of the stringent BODS and NH3 limits. There have been
several permit violations and NOVs issued by DWQ. The facility has sought technical assistance
from DWQ (June 2009) and the NC Rural Water Association Quly 2008) to help with trying to
correct treatment problems. Site visits and written recommendations have been given to the
facility to help bring them in compliance. It appears that during the hottest summer months,
compliance with BODS and NH3 are the most problematic. There is no mechanism to reduce the
facility's permit limits for BODS and NH3 and with the stream listed as impaired on the 303d list,
making discharge limits less stringent is not recommended.
See attached reported on limits and monitoring violations.
The Town of Denton is a member of the Yadkin Pee Dee monitoring coalition, so instream
requirements have been waived. At this time, however, there is no downstream monitoring
station in the vicinity of the outfall.
RPA Analysis
A RPA was conducted for existing limited/ monitored metals: mercury, nickel, copper
and zinc. Data from 2007 through May 2009 was input into the RPA and evaluated to determine
whether monitoring or limited were needed.
Copper and zinc- both parameters have NC action level standards that normally are not
limited unless they are shown to be causative of toxicity test failures. The RPA showed that both
parameters had reasonable potential to exceed the state action levels instream. However because
there are no ongoing toxicity test problems, will recommend that monthly monitoring for both
copper and zinc continue in the permit.
Mercury — there was detection in 23 of 24 samples submitted. The maximum predicted
concentration was greater than the allowable concentration and therefore showed reasonable
potential to exceed the water quality standard instream. A limit of 0.012 ug/I or 12 ng/1 will be
recommended to be put in the permit. This same parameter was deleted during the last permit
renewal however since January 2007, there have been three submitted data values that have been
greater than 12 ng/l. Based on this data, the facility's discharge does not show reasonable
potential to exceed mercury water quality standards. The limit will be removed and monitoring
reduced from 2/month to monthly.
Nickel - only 1 of 56 samples showed nickel levels above the detection limit. The
maximum predicted concentration was less than the allowable concentration. There was no
reasonable potential shown to exceed the water quality standard. It is recommended that the
nickel limit be dropped from the permit and that nickel continue to be monitored in the Denton

Additional data review
Facility did run PPAs for the renewal application. Most data was below detection however, there
were detected hits of chloroform and dichlorobromomethane. Will not recommend anv
monitoring for these parameters. They will be sampled in the next four PPAs.

WET Test Results
Self monitoring summary from January 2005 through April 2009 was reviewed. The
most recently submitted DMR (May 2009) indicated that Denton had failed its chronic tox test.
The facility has passed 16 of 19 WET tests within the past 5 years. The failures were in November
2006, February 2007 and May 2009. The cause for these failures has not yet been determined. It
is recommended that the chronic ceriodaphnia toxicity test at 90% be renewed for this permit
cycle. .

'PART E: TESTING DATA D4
„TOXICITY
POTWs meeting one or more of the following criteria must provide the results of whole effluent toxicity tests for acute or chronic toxicity for each of the
facility's discharge points: 1) POTWs with a design flow rate greater than or equal to 1.0 mgd; 2) POTWs with a pretreatment program (or those that are
required to have one under 40 CFR Part 403); or 3) POTWs required by the permitting authority to submit data for these parameters.
• At a minimum, these results must include quarterly testing for a 12-month period within the past 1 year using multiple species (minimum of two
species), or the results from four tests performed at least annually in the four and one-half years prior to the application, provided the results
show no appreciable toxicity, and testing for acute and/or chronic toxicity, depending on the range of receiving water dilution. Do not include
information on combined sewer overflows in this section. All information reported must be based on data collected through analysis conducted
using 40 CFR Pad 136 methods. In addition, this data must comply with QA1QC requirements of 40 CFR Part 136 and other appropriate QA/QC
requirements for standard methods for analytes not addressed by 40 CFR Part 136.
• In addition, submit the results of any other whole effluent toxicily tests from the past four and one-half years. If a whole effluent toxicity test
conducted during the past four and one-half years revealed toxicity, provide any information on the cause of the toxicity or any results of a
toxicity reduction evaluation, if one was conducted.
• If you have already submitted any of the information requested in Part E, you need not submit it again. Rather, provide the information
requested in question EA for previously submitted information. If EPA methods were not used, report the reasons for using alternate methods. .
If test summaries are available that contain all of the information requested below, they may be submitted in place of Part E.
If no hiomonitoring data is required, do not complete Part E. Refer to the Application Overview for directions on which other sections of the form to
