SUBJECT: Compliance Evaluation Inspection

NPDES Permit #NC0082949
Davidson County
Dear Mr. Gray:
Donald R. van der Vaart
Secretary
A compliance Evaluation Inspection was performed at the Town of Denton's WTP on March 3, 2015 by
Jenifer Carter of the Winston-Salem Regional Office. Ms. Tammie B. Melton, Operator in Responsible
Charge (ORC), was present for the inspection. This inspection consisted of a review of self -monitoring data
and an on -site inspection of the facility. The following observations were noted during the inspection:
• A review of self -monitoring data for the last two years did not reveal any NPDES permit limits violations.
All monitoring was performed and recorded per the frequencies specified in the permit.
• Upgrades to the plant are ongoing, and will include a new larger lined lagoon and new drying beds. With
regards to the ongoing construction, two preventative action items are noted:
o The new larger lagoon should have silt fencing installed during ongoing site work so that it does not
received a sediment load and, therefore, reduced settling capacity.
o Silt fencing was installed to keep sediment off of the temporary sludge storage area, but is still needed
on the back side of the stock piles in order to keep sediment on the site and out of nearby surface
waters. Although sites with land disturbance areas that are less than 1 acre do not require pre -approval
of Erosion & Sedimentation Control Plans, the requirement to keep sediment on site, as well as other
associated requirements, still apply.
As the Town knows, the town will be losing Ms. Melton, and will be designating a new ORC. Please make
sure the new ORC is able to work closely with onsite building contractors to ensure that proper operation of
the treatment systems continues to be possible during the ongoing construction.

> As per our conversation on 11-5-14; Our only lagoon is 3/4 full of sludge which leaves us almost no volume. There was
a leak discovered in the discharge line close to the manhole at back of lagoons, Dellinger discovered this when they were
digging to install the new manhole and pump station. They had asked that we not decant or wash any basins as treated
water was bubbling up in the area they were working. I let them know we had to a least be able to decant filter
backwash water and the rewash water at start up of the plant. They did not want water (treated, to come in there
working area).
> We had a meeting on this 11-5-14; we are to delay basin washing, but will have to be able to decant regular
operation water (or pump to side creek). They are to try and expedite the finishing up of the #1 lagoon. They have been
given permission to fix the leaking pipe and someone to camera the pipe will be here Tuesday.
> At 13:45 on 11-5-14 a filter had to be washed, and water went above the manhole in the lagoon causing some of the
water to escape the lagoon to the discharge pipe, it wasn't a lot but some did escape none the less. That is when I called
you.
> Also public works are trying to get #2 lagoon cleaned out. as per our conversation; they were wanting permission to
put the decant water off the top of the lagoon to the small creek to the right of the bearmed area for the alum sludge.
Because putting the clear water in the bearmed area would leave no room to put the sludge from the #2 lagoon. They
are doing all they can do to get this runny mess cleared out, it is very challenging but it is working.
> I did as you had asked, and took samples in both areas; at the manhole and the discharge site. The water looked good
at discharge and the water at the manhole was just a little cloudy. I have sent them off for testing and included metals,
TSS, turbidity, fluoride, total zinc, total iron, total copper, manganese, and aluminum. At the discharge site I did a up and
down stream turbidity also.
> I will send the results to you as soon as we receive them. And I will report the discharge site tests on the DMR.

SUBJECT: Compliance Evaluation Inspection

NPDES Permit #NC0082949
Davidson County
Dear Mr. Gray:
John E. Skvarla, III
Secretary
A compliance Evaluation Inspection was performed at the Town of Denton's WTP on May 20, 2014 by
Jenifer Carter of the Winston-Salem Regional Office. Ms. Tammie B. Melton, Operator in Responsible
Charge (ORC), was present for the inspection. This inspection consisted of a review of self -monitoring data
and an on -site inspection of the facility. The following observations were noted during the inspection:
The NPDES permit was recently renewed and became effective May 1, 2014. Continuous flow monitoring
is no longer required. Instead, instantaneous or estimated flow can be reported, along with duration of
discharge.
• A review of self -monitoring data for the last two years did not reveal any NPDES permit limits violations.
All monitoring was performed and recorded per the frequencies specified in the permit.
• Upgrades to the plant are ongoing, and will include a new larger lined lagoon and new drying beds. With
regards to the ongoing construction, two preventative action items are noted:
o Only one of two existing lagoons is being utilized while a new larger lagoon is constructed in place of
the other one. Since the need for the new lagoon is directly related to the reduced capacity of the
existing lagoons (due to hitting bedrock during their construction), it is vital to the functioning of the
only lagoon in use that it does not received a sediment load and, therefore, further reduced capacity.
o Dirt berms around the temporary sludge storage area need silt fencing around them to keep sediment
on the site, and out of nearby surface waters. Although sites with land disturbance areas that are less
than 1 acre do not require pre -approval of Erosion & Sedimentation Control Plans, the requirement to
keep sediment on site, as well as other associated requirements, still apply.
Ms. Melton continues to maintain optimal treatment conditions given the ongoing construction at the site,
and should continue to work with the contractor(s) on site to make sure their work does not impede her
ability to keep the WTP in compliance with all environmental permits and regulations.

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
Overall, the site was in compliance. There are two items of note that need to be addressed:
1.) Only one of two existing lagoons is being utilized while a new larger lagoon is being constructed to
replace the other one. Since the need for the new lagoon is directly related to reduced capacity (due to
hitting bedrock during its construction), it is especially important to keep sediment from the construction area
out of the only lagoon in use.
2.) Dirt berms around temporary sludge storage area (being utilized while new sludge drying beds are being
constructed) need silt fencing around them to keep sediment on the site, and out of surface waters (there is
a creek downslope of the bermed area). Although sites with land disturbance areas that are < 1 acre do not
require pre -approval of Erosion & Sedimentation Control Plans, the requirement to keep sediment on site (&
other requirements) still apply.

I did observe this and I don't see a problem with it.
I haven't written my report yet, but I was planning to mention the need to keep sediment from running into the old
settling basin from the ongoing construction work (even if it less than one acre, which I don't think the contractors
realized). They are replacing one of two old lagoons with a bigger one, among other things. The old lagoon cannot afford
a sediment load, as it is already lacking capacity (they hit bedrock when digging the two old lagoons, so they never had
the capacity they were supposed to have, which is why they are replacing one now).
They also need silt fencing outside of the dirt berms around the stockpiled sludge. There were no problem during my
visit, but there is a stream through the woods from where the berms are.
With the precautions taken, I don't see a problem with approving their request.

Laurie,
The plant is currently under construction, but the work is not being done near any creek. I spoke with the wastewater
ORC of the Water Treatment Plant to see if she knew of anything in particular that was happening on or before May 5`h
when the complaint came in. She wondered out loud if it might coincide with the removal of a manhole along the
discharge line. Flow from the creek does backflow up the line during heavy rain events, and the contractors noted heavy
sediment blockage in the line during the removal of the manhole.
The ORC walked the site after talking to me and just reported that she did not observe anything getting into the creek at
the discharge pipe, nor anything leaving the construction site that might drain to it or any other creek. She plans to talk
to Project Manager to see if he knows of anything in particular that happened, and to make sure he educates those
working under him to report anything unusual.
For your information, the person referred to as Genie is the Town Clerk, and is at Town Hall, not the Water Treatment
Plant. The ORC does not believe the complaint was ever passed on to plant personnel. I have left a message for Genie to
call me tomorrow morning to see if she has any further information than what you received.
I also have a planned inspection at the plant next week, so will have the opportunity to look around myself.
Considering the call came in 10 days ago, and that more specific information was not provided (i.e. where exactly the
'dumping' was observed) the case is considered closed unless something new arises.
Thank you for passing what you had along,
Jenifer Carter

It is our understanding that Salem Glen plans to add a food stand at the Country Club's pool. We understand
that there will be no change in the capacity rating of the facility, with no new sinks or toilets being installed.
There will not be a fryer or hood associated with the food service, so grease cannot and will not be
introduced into the Country Club's wastewater treatment plant collection system. All of these things being
true, there are no permits or certifications required from the Division of Water Resources for the installation
of the food stand. This does not preclude you from meeting any other Federal, State and Local requirements,

This sounds crazy. I don't see anything in or around the lagoons or the sed. basins. Our lagoon is a little muddy due to
the rain we received a couple of days ago. It was a gully washer. I will send pictures of basins and lagoons. It may take a
while, because we don't have good signal. I will have to go up the road to get them to send.... Wow. Thks... Tammie

Mr. Corey Basinger, Regional Supervisor

585 Waughtown Street
Winston-Salem, NC 27107
Dear Mr. Basinger:
The Town of Denton is currently undertaking a $4.4 million construction improvement project at its
Water Treatment Plant and needed to stock pile the alum sludge residuals from the waste lagoon so
that construction could begin.
The new alum sludge storage area is behind the #2 basin so the new berm area can drain into the #2
lagoon so as to keep the water out of the construction area, We had to move quickly so as not to
unduly hold up construction so Town forces completed the new berm area several weeks ago. The
residuals from the alum sludge storage area will be properly disposed of at the Davidson County Landfill.
Please accept my apology for the delay in getting this letter requesting the approval of your office of this
alum sludge storage area.
Please let me know if you have any questions.
Sincerely,
?John L. Gray

Dear Ms. Melton:
Review of Draft NPDES Permit
NCO082949
Denton Water Treatment Plant (WTP)
Davidson County
In response to your request to renew the subject NPDES permit, the Division of Water Resources
(DWR or the Division) hereby transmits this draft for your review and comment. Please review
this document to assure your understanding of the permit limits and monitoring conditions, and
to correct errors, if any.
The changes between this draft permit and the previous permit include the following:
• Fluoride, Phosphorous (TP) and Total Nitrogen (TN) monitoring will no longer be
required.
• A reasonable potential analysis (RPA) of the facility's Aluminum data indicated a
reasonable potential to exceed the EPA Human Health standard of 8000 µg /L. Please
note the draft permit requires monthly monitoring of Aluminum with a Monthly Average
Limit of 8.0 mg/L. The Town will have three (3) years from the effective date of this
permit to comply with the monthly average limit for Aluminum.
• A reasonable potential analysis (RPA) of the facility's Manganese data indicated a
reasonable potential to exceed the Water System (WS-IV) stream standard of 200 µg /L.

DRAFT, 2014
Page 2 of 3
The Division has included a permit re -opener clause in the permit for Whole Effluent
Toxicity Monitoring [Section A. (4.)]. The Division includes this condition if the
permittee has demonstrated toxicity failures during the past permit cycle. We note that
this facility has failed 5 of 8 quarterly tests during the past 2 years.
Proposed federal regulations require electronic submittal of all discharge monitoring reports
(DMRs) and specify that, if a state does not establish a system to receive such submittals, then
permittees must submit DMRs electronically to the Environmental Protection Agency (EPA).
The Division anticipates that these regulations will be adopted and is beginning implementation.
The requirement to begin r eporting discharge monitoring data electronically using the NC
DWR's Electronic Discharge Monitoring Report (eDMR) internet application has been added to
your NPDES permit. [See Special Condition A (3.)] For information on eDMR, registering for
eDMR and obtaining an eDMR user account, please visit the following web page:
http://portal.ncdenr.org/web/wq/admin/bog/ipu/edi-nr.
For information on EPA's proposed NPDES Electronic Reporting Rule, please visit the
following web site:
http://www2.epa.izov/compliance/proposed-npdes-electronic-reporting-rule.
Concurrent with this notification, the Division will solicit public comment on this draft by
publishing a notice in newspapers having circulation in the general Davidson County area, as
required by the NPDES Program. Please provide your comments, if any, to me via email
[[e-mail]] or write to my attention care of DENR / DWR / NPDES Program no
later than March 7, 2014. Your written comments are welcome but not mandatory.
Following the mandatory 30-day public comment period, the Division will review all pertinent
comments on your permit draft, and take appropriate action prior to issuing your NPDES permit
final. If you have questions concerning this draft, please e-mail me or call my direct line

NPDES Permit NC0082949
Facility Summary
This facility is a Conventional water treatment plant with discharge of wastewaters from media filter
backwash and sedimentation basins with a design potable flowrate of 2.25 MGD and a maximum monthly
average wastewater discharge of 0.0186 MGD. Because the waste flow is <50k gpd, continuous flow
monitoring is not required. Phosphorous (TP) and Total Nitrogen (TN) is not required because flow is <50k
gpd and not discharging to Nutrient Sensitive Waters (NSW) . The facility consists of the following water
and wastewater treatment units:
• filters,
• settling basins,
• two (2) 100,000 gallon decant lagoons and
• dechlorination.
In July 2011 DWR issued an Authorization to Construct (A to Z No. 082949A01). A start date in March
2014 is anticipated but construct is not under contract. This authorization was awarded for the following
modifications:
• Installation of a new 200,000 gallon backwash lagoon [one (1) existing 100,000 gallon decant
lagoon will remain];
• (one (1) existing decant lagoons will remain);
• a new sludge pump station with two (2) 225 gpm submersible pumps;
• two (2) 1,200 ft2 sludge drying beds; and
• an effluent flow meter.

Detention Time: Cur —rent: 10.75 Days After Upgrade: 16.13 Days
Toxicity — With an IWC >0.25%, this permit requires Chronic Whole Effluent Toxicity (WET) testing
using Ceriodaphnia dubia to be performed as a 7-day pass/fail test at 90% effluent concentration, during
January, April, July and October [TGP3B]. Five (5) out of the eight (8) toxicity tests over the past two
years were reported as "fail'. Therefore, DWR had inserted a toxicity re -opener clause [Section A. (4.)].
Renewal Summary — This permit reflects discharge at Outfall 001. DWR updated the facility description
and Map; added parameter codes to Section A. (L); added Electronic Reporting - Discharge Monitoring
Reports page. Added Permit Re -Opener for Whole Effluent Toxicity Monitoring [Section A. (4.)]
because of TOX test failure within three years; removed Fluoride monitoring; and removed Total
Phosphorous (TP) and Total Nitrogen (TN).
Stream — Discharge from WTP for Outfall 001 is into an unnamed tributary (UT) to the Yadkin River
[Stream Segment 12-(124.5)]. The segment from High Rock Dam to mouth of Cabin Creek [12-(124.5)a]
is currently listed as impaired in the 2012 North Carolina 303(d) List -Category 5 for Aquatic Life for the
parameters Chlorophyll a and Low Dissolved Oxygen.
RPA — A Reasonable Potential Analysis (RPA) was conducted on Copper, Fluoride, Zinc, Aluminum, Iron
and Manganese effluent parameters data because Discharge Monitoring Reports (DMRs) reported
concentration above method -detection levels (MDLs) for the past four and one half (4 1/2) years (May 2009-
Oct 2013). (The new 2014 Freshwater RPA - 95% Probability/95% Confidence was conducted prior to the
Draft permit with no changes to the following parameters.) [See attached RPA summary sheets.]
• Copper showed reasonable potential to violate state water quality standards (WQS). Since Copper
has an action level standard, quarterly monitoring will be maintained in conjunction with toxicity
testing.
• Fluoride did not show reasonable potential to violate state WQS; however, since the predicted
maximum effluent concentration was less than 50% of the allowable concentration no monitoring
will be required.
• Zinc showed reasonable potential to violate state water quality standards (WQS). Since Zinc has an
action level standard, quarterly monitoring will be maintained in conjunction with toxicity testing.
• Aluminum effluent data suggest reasonable potential to exceed the EPA Human Health standard of
8000 µg /L. Renewal requires monthly monitoring of Aluminum with a Monthly Average Limit of
8.0 mg/L. This limit will become active three (3) years from the effective date. Note: Looking at
sources for the high concentration of Aluminum in the effluent, there were no violations for TSS
noted in the data. The greatest value reported for TSS was 21 mg/L in August 2008. One reported
value of 12 mg/L of Aluminum exceeds the Human Health standard on 05/19/11. The reported
concentration of Aluminum may need to be verified with the laboratory.
Iron showed reasonable potential to exceed state water quality standards (WQS). Since Iron has an
action level standard, quarterly monitoring will be maintained in conjunction with toxicity testing.
Manganese effluent data suggest reasonable potential to exceed its standard of 200 µg /L. Renewal
will require monthly monitoring of Manganese with a Monthly Average Limit of 0.2 mg/L. This
limit will become active three (3) years from the effective date.
Fact Sheet
Renc%lA -- NPDES NC008-1949
Pike ,

Decant basins may not provide enough settling detention time resulting in higher effluent concentrations for
Aluminum and Manganese. The facility will undergo improvements including a new 200,000 gallon
backwash lagoon. This new lagoon may improve the concentrations of Aluminum and Manganese in the
long run.

Re: Residuals Improvements to Address Temporary Storage of Alum Sludge
Town of Denton WTP
NPDLS Permit NCO082949
Davidson County
Mr. Berry:
The Town of Denton continues to move forward towards construction of the proposed
improvements to address the temporary storage of alum sludge residuals on site. The proposed
improvements include:
Construction of a new 200,000 gallon backwash lagoon, sludge transfer pump station, and drying
beds (2) to improve alum sludge residuals management at the existing Denton WTP. One (1) of
the two (2) existing earthen lagoons will continue to be utilized for extended detention times,
extended settling, and redundancy as necessary for decant water to the NPDES permit. The
subnatant from the drying beds will return to the new backwash lagoon. The dried solids will
continue to be land -filled. The Town has received Authorization to Construct approval from
DWQ and PWS for the proposed upgrades.
This project has been recently delayed as outlined below:
• March. 2012 — NC DENR / PWSS informed the Towit of Denton they were to receive g2.4 M in principal
forgiveness and the remaining S1.204M in 09 loan under the 2011 DWSRF program. We discussed
with Denton and replied to NC DENR / PWSS by e-mail we desired these terms.
• March, 2012 — Denton requested clarification from DWQ on expectations for NPD1S permit compliance
via my e-mail of March 8, 2012
• 3/22/12 —NC DENR / PWSS formally submitted the PROJECT request to LGC for approval with the loan
terms outlined above
• 6/4/12 —NC DENR / PWSS notified the Town of Demon's engineering agent via e-mail "there were
additional documents needed before they could issue the Part A (Offer and Acceptance of the Loan
Agreement)" including an update to the Town's Water System Management Plan (WSMP) and a clear
site certification. Prior to 6/4/12, we had reasonably assumed we had met RTP status based upon the
prior submittals deeming the WSMP complete. We received no indication to the contrary from PWS
between 3/22/12 and 6/4/12. The clear site certification was submitted in August. 2012, with the
updated WSMP. but could have been subnutted at any time prior to 5/31/12 had it been communicated
to us we were not in RT11 status as of 3/22/12 when the project went forward to LGC. As staled, there
were no land acquisition requirements associated with the project.

Waste Not Discharged to Surface Waters 15A_NCAC_02T.pdf
Hello Tammie and Troy:
I have spoken to my supervisor, Sherri Knight, and would like to provide clarification on the following issues, most of
which will be included in a Notice of Violation (NOV) letter. Thanks in advance for your attention to these matters:
1) Town Manager on file; I was able to update our database to reflect Victor Pizzurro as Town Manager and no
further action is required;
2) Our database does list Troy Branch as the primary ORC, however, a back-up ORC is required. The Town of
Denton will need to designate a back-up ORC. This may be accomplished either by having Tammie complete the
training and/or designating an operator from Southern Soil Builders;
3) The 'Signature of Preparer' on Annual Land Application Certification Form (DENR FORM ACF) is the signature of
the ORC that prepares the residual to meet pathogen/vector attraction reduction as defined in 40 CFR Part
503.9. It is my understanding that Troy Branch currently prepares the residual and therefore is correctly signing
the certification form. However, no 'land applier' signature was provided on 2011 or 2012 Annual Reports;
4) Annual Reports for 2011 and 2012 submitted to DWQ were incomplete. I have received some data from Zach
Key (Southern Soil Builders) and will be requesting in the NOV letter both reports be resubmitted;
5) Three issues noted from review of 2011 and 2012 annual reports -
a. Not all land application events were documented (both in 2011 and 2012)
b. pH temperature correction calculations were incorrect
c. Lime stabilization for the December 14, 2012 event illustrated a failure to stabilize prior to land applying
d. Field 5 pH is 5.3 and the permit requires pH>6. For fields where lime stabilized residual is applied this
typically is a non -issue, however, additional lime will need to be added if future soils analyses
demonstrate this deficiency;
6) Nuisance conditions at land application site, Field 4; countless feminine hygiene plastics were observed on Field
4 and require removal;
7) All records associated with the Friday, May 3, 2013 land application event will need to be submitted. Please
send hauling records, lime stabilization calculations, field summary form, an estimate of how many acres were
utilized (i.e. percentage of Field 4's 16.60 wettable acres that received residuals) AND verification of land
application equipment calibration;
8) Records of all WTP residuals (Oct. 2012 and April 2013?) transported by Newsome Grading will need to be
submitted. This should include dry tons removed/disposed/applied as well as location of where residuals were
land applied or disposed;
9) The NOV letter will request a realistic timeline to ending the temporary storage of WTP residuals. Brad Bucy of
Hobbs & Upchurch contacted me last week and stated he would send a letter outlining a timeline for
construction to commence at the WTP. I will notify both of you if/when I receive his letter; your assistance in
assuring DWQ receives this letter is greatly appreciated. Additionally, filter media stored (outside of fenced
area) at WTP is a residual as defined by 15 NCAC 2T .0103(30) (ref., Attachment). The recommendation will be
removal of this residual as the temporary storage provision expires. This residual could be analyzed and land
applied according to the permit or disposed of properly in a landfill. And,
10) Due to the number of issues identified during this inspection and to alleviate concerns about how the Town of
Denton is managing its residuals, please notify me, at a minimum of 24 hours, prior to your next land application
event (June 2013?).

I expect the NOV letter to be sent this week and the Town of Denton will have 30 days from receipt to submit a
complete response. If any questions arise, please contact me.
I look forward to hearing from you.

Subject: NPDES Permit Compliance Evaluation
Town of Denton WTP
NPDES Permit NCO082949
Davidson County
Dear Ms. Melton:
The Division of Water Quality (DWQ) has received your e-mail correspondence of March 8, 2012,
requesting clarification regarding DWQ's expectations with regard to operations at the Town's water
treatment plant (WTP). The primary concern expressed by the Town was DWQ's determination of
compliance with NPDES permit conditions, specifically how potential delays in completion of the WTP
upgrade project (which includes improvements to wastewater treatment infrastructure) may affect the
WTP's compliance status.
As you know, the State implemented a new strategy in 2007 for the regulation of wastewater discharges
from WTPs. The strategy's goal is to better protect surface waters through the identification of
pollutants characteristic of WTP wastewater discharges. The strategy was implemented for the Town of
Denton WTP during its 2009 permit renewal. The renewed permit required new or modified monitoring
for a number of parameters, most notably flow and whole effluent toxicity. The permit called for flow
to be monitored continuously, but provided an eighteen month compliance schedule for the installation
of an adequate flow measurement device. The compliance schedule was modified in 2011 to extend the
deadline for installation of the flow meter until January 1, 2013, in accommodation to the schedule of
the overall WTP construction project. The whole effluent toxicity requirement within the permit called
for monitoring only, but was to be reported as "pass" or "fail" with regard to the toxic effects of the
discharge on aquatic life. Since the monitoring requirement was instituted the WTP has reported
failures on seven of eight whole effluent toxicity tests.
Inherent in the issuance of NPDES permits is DWQ's firm expectation that permittees can and will
comply with the conditions contained therein. DWQ is required to enforce compliance of the permits it
issues. In the case of the Town of Denton WTP, DWQ feels that the extension of the compliance
schedule granted in the 2011 permit modification has provided the Town adequate time to install a
suitable flow measurement device. Documentation of all volumes of flow discharged by the facility is a
very important issue in determining its potential impact on water quality. As such, we will not grant any
additional extension of time in this matter. Therefore, if the flow meter is not installed and continuous

flow measurements are not being reported by the January 1, 2013 deadline, the facility will be
noncompliant with the terms of the NPDES permit and may be subject to appropriate enforcement
action.
While there is currently no compliance evaluation in the matter of whole effluent toxicity testing, the
facility's reported failures of toxicity tests are of concern to DWQ. It is possible that future permits will
have requirements to identify and eliminate the causes of the toxicity failures. Therefore, the Town is
encouraged to complete its wastewater treatment upgrades at the WTP as soon as possible.
A final matter of concern to DWQ involves the facility's long term strategy for management of waste
solids generated by the facility. Too high accumulations of solids in the lagoons at the site have been
cited in past inspections as the cause of solids escaping the treatment works and entering the receiving
stream. This matter was initially resolved by the facility depositing excess solids within a bermed area
adjacent to the lagoons. However, this arrangement was approved only as a temporary means for the
storage of solids. The facility upgrade calls for improvements in the facility's ability to manage its
solids inventory. These improvements have the potential to resolve a long standing problem at the
facility, and to enhance the quality of the wastewater it discharges. DWQ finds these to be compelling
reasons for the Town to complete the project as soon as possible.
DWQ appreciates the Town's commitment to protection of the state's water resources. Please contact
the staff of the Surface Water Protection Section within the Winston-Salem Regional Office at (336)
771-5000 should you require any assistance with onsite matters. If you have any questions about this

Dear Sirs and or madams, 4
We at the Town of Denton spectfully request an extension on one item on our permit
issued November 2, 2009, permit number NC0082949. We are asking for a minor
modification.
We are requesting a longer time frame for the installation of flow monitoring equipment
for our lagoons discharge. Specifically we are requesting that we be allowed to collect
grab flows weekly as we were doing prior to the March 2011 deadline, given by your
office. This is due to the extended submittal of the plans and the funding time frames.
Plans were submitted to your office on May 26`h, 2011 by Brad Bucy with Hobbs and
Upchurch, for your review. (This has the time frames on it) Part of the request is
extending the deadline to Dec. 31, 2012. This should allow for everything that needs to
be done. We will contact your office when it completed.
It would be a hardship for the Town of Denton, if something were to be put in at this
point, as funding for this is included in the upgrade. If something were to be put in now,
it would still have to be approved by your office, and it would have to be taken out during
the upgrade. We at The Town of Denton want this project to be done so that we are
incompliance with our permit, and done so that it will serve as an effective means of flow
determination for years to come, and not be piece milled with possible problems in the
future. We have a limited staff at the Water Treatment plant and safety issues could result
in collecting daily flow samples as we have killed snakes at the outfall site. Two people
need to collect samples due to this. Some days there is only one operator here at the plant.
Our schedule now is set so that we can have two operators on duty the day that we
collect.
We ask for any and all consideration and discretion that DWQ would allow on this
project. We have been diligent in making sure, through sheer dedication of operators and
myself; that we comply with all directives given by your office. Please consider our
request.
Respectfully,
Tammie Melton

Tammy,
Bob Sledge recommended that you just prepare a letter requesting the permit modification that we've discussed rather
than completing a permit modification form.
Your letter should provide as much detail as possible relative to the Town's request and include a projected time frame
for completion of the necessary upgrades.
The fee will still be required and is $260 made payable to NC DENR — Division of Water Quality. This should save you
some time by not having to complete the form.

SUBJECT: Annual Report Review (2006-2008) and Additional Information Request
for Permission for Temporary Storage of Alum Residuals (August 28, 2006)
and the Extension of the Temporary Storage of Alum Residuals
Town of Denton
Town of Denton Residuals Land Application Program
Permit No: WQ0016966
Davidson County
Dear Mr. Isenhour:
Additional information was requested on January 8, 2010 in addition to Annual Report Review conducted on January 8,
2010. The request was to follow up on a Permission for Temporary Storage of Alum Residuals issued on August 28,
2006. The additional information was received on February 10, 2010.
Upon review of the additional information it was noted that an engineering firm was hired to make design improvements,
which includes expanded sludge backwash lagoons. These lagoons will include geotexile or concrete liners, sludge
transfer pumps, and on site drying beds with an appropriate underdrain system. The design will also evaluate the use of a
sludge removal system either for existing basins and/or the proposed improvements. It is our understanding that the Town
of Denton is budgeting funds through a Loan Application currently filed with USDA Rural Development. These
improvements to the water plant are anticipated to be completed by the end of 2011. In addition, hauling records and
receipts were provided that indicated proper disposal of the residual solids.
This additional information satisfies the requirements to find an ultimate solution for treatment and proper disposal of the
Alum Residuals that were outlined in the August 28, 2006 letter.
Upon review of the information the Winston-Salem Regional Office of the Division of Water Quality Aquifer Protection
Section grants an extension to the permission for the temporary storage of alum sludge in the trenched area adjacent to the
lagoon provided that any runoff would flow into the lagoons. Please notify the Aquifer Protection Section Winston-Salem
Regional Office when construction for the improvements begins and are completed. A permit modification application
with proposed plans will need to be submitted to the Surface Water Protection Section when prepared.

Dear Mr. Isenhour:

Dee Freeman
Secretary
A compliance Evaluation Inspection was performed at the Town of Denton's WWTP on December 11,
2009 by Jenifer Carter of the Winston-Salem Regional Office. Ms. Tammie B. Melton, Operator in
Responsible Charge (ORC), was present for the inspection. This type of inspection consists of two basic
parts: an in office review of facility files and self -monitoring data, and an on -site inspection of the facility.
A review of self -monitoring data for the period of November 2007 through October 2009 revealed no
limits violations. All monitoring was performed and recorded per the frequencies specified in the permit.
The two lagoons on site were originally designed to be much deeper than they are because bedrock was
exposed during construction. The Aquifer Protection (AP) Section of the Division of Water Quality
granted temporary permission to store alum sludge in drying beds next to the lagoons in a letter dated
August 24, 2006, while alternatives to increasing treatment capacity and sludge removal were
investigated. Plans for upgrades, drafted by Hobbs & Upchurch include two new lined lagoons, back
flow prevention, continuous flow monitoring equipment and a new drying bed.
The plant was operating properly at the time of the inspection. Ms. Melton has done a good job
maintaining optimal treatment conditions given the limited sludge storage available.
Should you have any questions please contact Ms. Jenifer Carter in our Winston-Salem Regional Office at
[phone].

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
As noted in the previous inspection report, the WTP does not have the sludge capacity in the lagoons that
they were designed to have due to rock being struck during their construction. This has presented a
challenge, especially during wet weather. As a result, they have been given temporary permission by the
Aquifer Protection Section to store alum sludge in drying beds next to the lagoons while alternatives are
investigated.
Hobbs & Upchurch have been hired to help out with the upgrades, which may begin sometime in 2010. In
the DRAFT plans, improvements include two more lagoons with liners, back flow prevention, continuous
flow monitoring equipment and a drying bed.

Enclosed with this letter is a copy of the draft permit for your facility. Please review the draft very
carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit a number of changes in the monitoring requirements from those found in your current
permit. These changes were made as part of the NPDES strategies for wastewater discharges from
potable water treatment plants, which are being implemented throughout the state as permits are issued
and/or renewed. Some of these changes are:
• The facility has been given a flow limit based on the highest reported flow that occurred over the
past three years.
• Monitoring requirements for Settleable Solids and Turbidity have been removed from the permit.
• Monitoring requirements for Calcium, Magnesium, Manganese, Fluoride, Copper, and pH have been
added based upon studies of discharges from conventional water treatment facilities. Please note the
permit contains provision for reduction or removal of monitoring for particular parameters if it can
be shown there is no reasonable potential for their presence in the effluent.
• Monitoring requirements for Total Zinc and Ammonia Nitrogen have been added to the draft permit.
If the facility does not use and does not plan to use either zinc orthophosphate as a corrosion
inhibitor or chloramines as an alternate form of disinfection, these parameters may be removed from
the final version of the permit.
• The monitoring frequency for Aluminum has been reduced to quarterly; monitoring for Total Iron
has been reduced to monthly.

monthly monitoring will begin immediately. Upon submission of a valid test, this monthly test
requirement will revert to quarterly in the months specified above.
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.
If the Permittee monitors any pollutant more frequently then required by this permit, the results of such
monitoring shall be included in the calculation & reporting of the data submitted on the DMR & all AT
Forms submitted.
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.

Dear Mr. Isenhour:
Alan W. Klimek, P.E. Director
Division of Water Quality
On June 22, 2005 Shannon Thornburg with the Central Office gave a verbal agreement to Chris Alexander with Precision
Land Application, Inc. for the Town of Denton WTP granting approval for a temporary one-time stockpiling of the WTP
residuals within the bermed area. This agreement required that the material had to be solid and there would be a time
limit on the stockpiling and that a formal request letter should be submitted to the Central Office so that a written approval
could be issued. Chris Alexander submitted a formal letter to the Central Office on July 27, 2005. This letter sought
permission "to store, on a temporary basis, dried alum sludge from their Water Treatment Facility". Specifically, the
letter sought permission "to store dried alum sludge adjacent to the two alum sludge lagoons on the WTP's property". It
was indicated in the letter that "the two alum lagoons are surrounded by an earthen berm that provides adequate storage
area within the berm for the dried alum sludge" and that "all surface runoff from rain water would be contained with the
berm and drained into the two alum lagoons".
An inspection on August 4, 2005, by Steve Mauney with the Winston-Salem Regional Office Division of Water Quality,
for NPDES Permit No. NCO082949 found the Town of Denton WTP to be in violation for the following:
That the treatment basins at the Denton Water Treatment Plant need to be cleaned out so that they can properly
settle the solids generated in the water purification process. Solids have escaped the treatment facility and
reached the receiving stream. (There appears to be adequate room to store the solids within the earthern-diked
area at the facility.)
A permit renewal and modification was received on October 10, 2005 for the Town of Denton's Land Application of
Residual Solids Permit No. WQ0016966, which included the addition of the Town of Denton WTP as an approved
residual source -generating facility for 160 maximum dry tons per year. On May 26, 2006, the permit renewal and
modification was issued with the Town of Denton WTP listed in Attachment A.

From a phone conversation with Tammy Melton, ORC, with the Town of Denton WTP, it is our understanding that the
Town of Denton seeks permission to continue to store alum sludge in a trenched area adjacent to the lagoon where any
runoff would flow into the lagoons under Non -discharge Permit No. WQ0016966. It was also understood that there were
concerns about the lining of the present lagoons in reference to any requirements needed to be met to be in compliance
with groundwater standards.
Upon review of this information the Winston-Salem Regional Office of the Division of Water Quality Aquifer Protection
Section grants permission for the temporary storage of alum sludge in the trenched area adjacent to the lagoon provided
that any runoff would flow into the lagoons and that a permanent storage method would be constructed such as additional
lagoons and/or drying bed. Operation of this method of storage should be in compliance with performance standards in
Condition 1. Land 3. of Non -discharge Permit WQ0016966 and in compliance with NPDES Permit No. NC0082949.
Previous inspections indicated that saprolitic material or weather bedrock has been exposed in the lagoons. Maintenance
of the lagoons should be implemented to prevent further erosion and rock exposure. Minimum design requirements that
apply to the present lagoons, any proposed lagoon, and trenches such as the ones that are being used temporary to store
alum sludge are found in North Carolina Administrative Code 15A NCAC 02H.
Carefully review all permit conditions and design requirements addressed in this letter and respond in writing to this
office within thirty (30) working days of receipt of this letter. If you should have any questions, please do not hesitate to
contact Derek Denard or me at 336-771-5000.

In the event that the facilities fail to perform satisfactorily, including the creation of nuisance
conditions, the Permittee shall take immediate corrective action, including those as may be required by this
Division, such as the construction of additional or replacement wastewater treatment or disposal facilities.
The Winston-Salem Regional Office, telephone number [phone], shall be notified at least
forty-eight (48) hours in advance of operation of the installed facilities so that an in -place inspection can be
made. Such notification to the regional supervisor shall be made during the normal office hours from 8:00

Permittee must also employ a certified back-up operator of the appropriate type and grade to comply with
the conditions of Title 15A, Chapter 8A, .0202. The ORC of the facility must visit each Class I facility at
least weekly and each Class II, III, and IV facility at least daily, excluding weekends and holidays, and

all other conditions of Title 15A, Chapter 8A, .0202.
A copy of the approved plans and specifications shall be maintained on file by the Permittee for the
life of the facility.
Failure to abide by the requirements contained in this Authorization to Construct may subject the
Permittee to an enforcement action by the Division of Environmental Management in accordance with
North Carolina General Statute 143-215.6A to 143-215.6C.
The issuance of this Authorization to Construct does not preclude the Permittee from complying
with any and all statutes, rules, regulations, or ordinances which may be imposed by other government
