Dear Mr. Oakley:

Subject: Issuance of NPDES Permit No. NCO003042
Roxboro WTP — PC-1
Person County
Division (DWQ) 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 15,
2007 (or as subsequently amended).
Your March 5, 2012 letter indicates the City of Roxboro is currently designing upgrades to your
facility, which will direct the existing WTP discharge to your existing WWTP. Construction for these
planned upgrades should start by the Spring of 2013. Because of these planned upgrades, you
requested that new monitoring requirements, contained in your draft permit, be postponed for three
years. These new monitoring requirements have been in place since October 2009.
After review of your application, the DWQ has made the following changes to your draft permit:
. Flow monitoring has been changed back to Instantaneous.
• Zinc monitoring has been removed because no Zinc Orthophosphate is used your treatment
system.
• Notification / reporting condition for Zinc added in 'Supplement to cover sheet" #3
• The downstream sampling site has been changed back to 100 feet.
• Special condition A.(3) has been added.

These are the only changes to the draft permit the DWQ has authorized because proposed
construction of your upgrades will not begin until spring"2013. Please note that the receiving stream
is listed as an impaired waterbody on the North Carolina 303(d) Impaired Waters List. Addressing
impaired waters is a high priority with the Division, and instream data will continue to be evaluated. If
there is noncompliance with, permitted effluent limits and stream impairment can be attributed to your
facility, then mitigation measures may be required.
The DWQ applauds and encourages your efforts to upgrade your facility and eliminate this point
source discharge. However, we cannot allow reduced monitoring during this two year proposed time
frame because of'your discharge is to 303(d) Impaired waters, and the completion of the project is far
into the future.
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 150E of the North Carolina General Statutes, and filed with the Office of
Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-6714). Unless
such demand is made, this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The, Division may
require modification or revocation and reissuance of the permit. This permit does not affect the legal
requirements to obtain other permits, which may be required by the Division of Water Quality, or
permits required by the Division of Land Resources, the Coastal Area Management Act or any other
Federal or Local governmental permit that may be required. If you have any questions concerning
this permit, please contact Bob Guerra at telephone number [phone] or email at

Footnotes:
1) The discharge from this facility shall not cause turbidity in the receiving stream to exceed 50 NTU', If the
instream turbidity exceeds 50 NTU due to natural background conditions, the discharge cannot cause
turbidity to increase in the receiving stream.
2) Upstream = 100 feet from discharge, Downstream = 100 feet from discharge.
3) The Division shall consider all effluent TRC values reported below 50 ug/I to be in compliance with the
permit. However, the Permittee shall continue to record and submit all values reported by a North
Carolina certified laboratory (including field certified), even if these values fall below 50 ug/l.
4) Parameter should be monitored in conjunction with toxicity test.
5) See Part I, Condition A. (2.). Further studies may be required to determine the -cause of toxicity, if any.
The collection of samples shall'coincide with the sampling of other parameters.
There shall be no discharge of floating solids or visible foam in other than trace amounts
All samples collected should be of a representative discharge.

Permit NCO003042
A. (2.) CHRONIC TOXICITY MONITORING (ANNUALLY)
The permittee shall conduct quarterly chronic toxicity tests using test procedures outlined in the "North
Carolina (Ceriodaphnia Dubia) Chronic Effluent Bioassay Procedure," Revised February 1998, or
subsequent versions.
The effluent concentration defined as treatment two in the procedure document is 90%. The testing shall be
performed as a Ceriodaphnia dubia 7day pass/fail test. 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.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B.
Additionally, DWQ Form AT-1 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, N.C. 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no
later than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete and accurate and include all supporting chemicallphysical measurements performed
in association with the toxicity tests, as well as all dose/response data. 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 Section at
the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, then 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 than 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.

Permit NC0003042
A. (3.) ELIMINATION OF DISCHARGE
Should the permittee fail to eliminate the wastewater discharge and request rescission of NPDES Permit NC
00003042 by May 4, 2015, the measurement frequency requirement for flow will changed from 2/month to
continuous and the sample type shall change from Instantaneous to recording.

Facility comments per WTP Strategy
Facility has responded with documented requests.
Facility is moving forward with plans to tie in this
discharge to existing WWTP within two years of permit
issuance. Facility requests that the following new testing
parameters be changed to coincide with elimination of
discharge:
• Change flow monitoring back to Instantaneous.
• Remove Zinc monitoring because no Zinc
Orthophosphate is used in system
• Change downstream sampling back to 100 feet
because of safety reasons
• Change new testing frequencies from Quarterly to
annually for Aluminum, Fluoride, Iron,
Manganese and Aquatic Toxicity.
Final permit includes the following changes:
• Flow monitoring has been changed back to
Instantaneous
• Zinc monitoring has been deleted ( none used in
treatment train)
• Downstream sampling location has been
changed back to 300 feet.
Majority of changes are rejected because:
• Facility is one of the few remaining WTP to have
them incorporated into renewal permits.
• Proposed construction activities to reroute WTP
discharge to existing WWTP are two to three
years from planned actions.
• Facility discharges to UT to Marlowe Creek,
which is one the DWQ 303(d) impaired waters list
for Zn and Cu.

Changes to.the Previous Permit:
• This section of Marlowe Creek is listed as impaired for Copper and Zinc with notation of cover
letter about Impaired Stream status
• Special Condition A (3) added
• Limits and monitoring for Settleable solids deleted
• The site map has been updated to reflect lat & long values for your discharge point,
• Footnotes have been modified and added.
o Reporting condition #3 added in "Supplement to cover page" requiring facility to report
backwashing with waters containing Zinc. This was added to protect receiving stream,
which is impaired for Cu and Zinc if facility changes process during current permit
cycle.
• Parameter codes have been added to the effluent page.
Sampling frequencies have been changed for:
o Flow changed from weekly to 2/month.
o TRC from Weekly to 2/Month
o Instream Turbidity sampling changed from weekly to 2/Month
o pH changed from weekly to 2/Month
o Total Iron changed from weekly to Annual sampling
Additional monitoring requirements have been added for the following Pollutants of Concern:
o Quarterly sampling for
■ Manganese
■ Aluminum
■ Manganese and
■ Fluoride
o Chronic Toxicity Monitoring — Quarterly sampling at 90 % IWC

Roxboro Water Treatment Plant -- Class PC 1

Dear Mr. Guerra,
This letter is in response to the Draft NPDES Permit dated January 18, 2011 that
was sent to us from your office. The date of the letter was January 18, 2012, but
we did not receive it until February 13, 2012. We have reviewed the draft permit
and the changes that were included therein.
Firstly, in our review we discovered that the standard conditions were not the
most recently approved. We request that the standard conditions reflect the
November 9, 2011 update. (�( otk
In regards to the additional monitoring, the City is currently designing an upgrade
to our water treatment facility for removal of disinfection byproducts and as a part
of that upgrade our wastewater will be directed to our wastewater treatment
plant, thus eliminating our discharge. Currently the upgrades are expected to be
permitted by August 2012, bid in the Fall of 2012, and construction started by
Spring of 2013. The first phase of the construction would need to be the
construction of a pump station for the wastewater and within two years we would
hope to eliminate this discharge. As such, we request that the monitoring
requirements for copper, zinc, fluoride, aluminum, iron, Chronic Toxicity and
manganese be annual. We request that the sampling for Instream Turbidity be
quarterly. We -ask that since _we-,hope-�to eliminate the_discharge=in two=years`that
these -new monitonngjgquirements are -postponed for,three,years.
105 S. LAMAR STREET • P. 0. BOX 128 • ROXBORO, NORTH CAROLINA 27573 • [phone] • FAX [phone]
www.roxboronc.org

The City would like to keep the sampling location at its current location, due to
entry onto private property and since we are eliminating the discharge it would
not be advantageous to establish a right of entry for just two years.
If any comments are generated from the public comment period, the City would
like the opportunity to address them prior to issuance of the permit. Please call
me at [phone] or email at aoakleva-citvofroxboro.com, if you would like to
discuss these issues. We appreciate your help in helping to facilitate the permit
renewal process and look forward to speaking with you.

Mr.Berry
we went to the water Plant for Orange water And Sewer Authority and took a tour
that was helpful. I still have some question for you?
If we have to add chemicals to dechlorinate, will this make us a chemical
treatment plant?
If the water plant adds chemicals at the water plant to dechlorinate all the water
before it comes to the lagoon,will this effect the lagoon NPDES permit any?

Subject: Inquiry On WTP That Use Dechlorination
Mr. Oakley.
In response to your inquiry about other Water Treatment Plant that are
similar to Roxboro WTP and are having to dechlorinate their effluent to
meet NPDES Permit Limits, I located the following plants:
1.) Orange Water And Sewer Authority Phone: [phone]
2) Rocky Mount Water Treatment Plants (2 plants) Phone: [phone]
Also, for more information on standard installation and designs,
submitting and gaining approval for the dechlorination equipment I would
refer you the following web site listing:
Go to www.nccgl.net/
Select Logo "Permits & Engineering"
Scroll down to Menu Heading "Fast Track Authorization To
Construct For Dechlorination
You will note several subject to choose from including construction
application.
I hope this information is helpful.

Mr.Oakley,
I discussed the operator certification requirements with the Certification Division
in regards to the addition of dechlorination. At this time they will continue to
require only an operator certification of PC-1 for your plant. In regards to your
second questions the only effect to the effluent that may be a potential concern is
the lower pH. However, this may be a small effect and depends on the amount of
chlorine that is neutralized.
I hope this information is helpful.
