we went to the water Plant for Orange water And Sewer Authority and took a tour

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?

hey Ron, I looked over the permit and I feel you covered everything. I know when I
done the last inspection I told them they needed to start looking at how they are
going to meet the new standards for TRC.
I totally agree with your 4 points below.
Thanks,

Vickie,
Attached is pdf file for the Roxboro WTP NCO003042 Permit Draft. You may have
already received a hard copy by mail. I need any input or "No Comment" you may
have on this draft.
After reviewing the draft Andrew Oakley, Roxboro Public Service Director has
requested an additional 6 months beyond the 18 months stated in the draft to be in
compliance with the TRC limit. At this point I will reply to the request and
state:
1) that we will not amend the draft compliance, it is the standard compliance we
apply to all permittees
2) that we expect Roxboro to properly measure and report applicable Cl values
under any permit including the current one
3) that we expect Roxboro to work towards meeting the 18 month compliance time
line the same as other WTPs
4) that at such a time approaching the 18 month dead line in the future Roxboro
feels it cannot meet the 18 month time line then they can make a request
Based on the DMR reports and annual inspection reports Roxboro has had some
problems historically with correctly reporting C1 values. I am not sure what there
perception is on measuring values in the 17Ag/L range.
If you have any additional thoughts let me know.

Re: Draft NPDES Permit

Roxboro Water Treatment Plant
Person County
Dear Mr. Berry,
This letter is in response to the Draft NPDES Permit dated July 13, 2007 that was
sent to us from your office. We have reviewed the draft permit and the changes
that were included therein.
In regards to the addition of a limit on Total Residual Chlorine (TRC), the effects
of this limit on our Water Treatment Plant are unclear until a monitoring plan can
be established to identify a baseline for our plant's effluent at this time. The 18
month time constraint may not be sufficient for analyzing the situation and
making plant or system modifications that would be necessary. The city will
gather data for both winter and summer months. Then if action is needed to
correct any TRC problems, the city could possibly needed to enter into an RFP
for consultants and bid out work for corrective actions. We would request that
the time frame be extended for at least 24 months.
The City would like to have 6 months to develop a procedure for monitoring the
PH required by this permit. The additional 6 months would allow us adequate
time to verify that existing equipment will be available for monitoring PH or if new
equipment might need purchasing.

If any comments are generated from the public comment period, the City would

me at [phone] or email at aoakley cityofroxboro.com, if you would like to
discuss these issues. We appreciate your help in helping to facilitate the permit

Thank you for clarifying the page issue. As far as the status of the current renewal application it is still
being reviewed. But you are still covered by your last issued permit until a new one is issued. At this
point with the additional information you provided the paperwork appears complete. The stream that is
impacted by your discharge is listed on the impared stream list and automatically requires additional
scrutiny by NC-DENR, just as any other discharges sources entering an impared stream will be
scrutinized.

CONVERSATION WITH ROANOKE BASIN COORDINATOR — NORA DEAMER
Date: 6/8/07 3:45 pm
Based on current information the Roxboro WTP is discharging into an impaired stream,
Marlowe Creek. Contacted Nora as basin coordinator for input and direction on
monitoring and/or new limits for permit. Current 2006 Plan fro Marlowe Creek is focused
on storm water runoff control by the City of Roxboro. Copper is sited as possible source
of impairment but do not know of any potential source in WTP discharge. Agreed we
would include Nora in cc distribution on permit draft. Nora provided web site link
(already had visited) and a hard copy of the approved 2006 plan with map. Referred to
2006 plan for most current information.
Talked to Jim about this and he does not see any additional monitoring requirements
beyond what we had planned, pH and TRC. Jim did suggest checking back with DMR to
see if any metals were monitored. OK with adding Nora too cc draft.

Arnold Oakley, City of Roxboro WTP, called in response to my earlier call to Mr.
Warren 6/5/07. He wanted to know besides the missing WTP flow schematic was there
any other information needed. I reviewed what was required for the flow schematic and
asked him to mark where the grab sample was taken. I also asked him about the "Water
Softener" check box that was checked on the application. It stated it was checked in error
and the WTP plant operation had not changed. Mr. Oakley requested my email address
which I did provide.
Date: 6/7/07 1:45pm
Vicki Webb called from the Regional Office in response to my email and previous phone
message in regards to Roxboro WTP. There is no turbidity measurement occurring in the
grab sample and we both agreed the 50 NTU limit posted under the daily max could be
removed. The actual 50 NTU limit will be clearly visible in the limit table footnotes and
will be applied against the upstream/downstream measurements (as currently done).
Vicki did state that several references to the pH needing to be added were in her reports,
same on this end. The pH measurement and its limits will be added to this permit.

He stated he needed to pass this request on to another gentleman, Arnold, who should be
able to supply the requested information. He felt like this could be done this week. I gave
him my extension number and office: location in DENR Raleigh.

Surface water
7. Describe the treatment process(es) for the raw water:
Seasonal Potassium Permanganate added at source water intake for iron, manganese, and
taste and odor. Aluminum Chloride for coagulation, Cationic Polymer for coagulant aid,
Sodium Hydroxide for PH adjustment, is added in the flash mix. Water goes through
flocculators then to settling basins then to multimedia filters at which point chlorine is
added.
S. Describe the wastewater and the treatment process(es) for wastewater generated by the
facility:
The wastewater is treated by retaining it in a decant lagoon. The solids settle out and the
clear water is discharged to the stream. The settled solids are pumped out to 1 of 2
additional decant lagoons. Clear water from these 2 lagoons is returned to the first lagoon
in the system. The concentrated solids in the 2 additional lagoons is released into 2 solar
drying beds and any Clearwater is returned to the first lagoon in the system. The
wastewater is from the settling basins, filter backwash, and filter to waste for plant
startup.

Sludge Management Plan
All wastewater released from the water treatment plant flows into our wastewater
lagoon. The solids are allowed to settle out here and then pumped to our holding pond.
Then the solids are released into our drying beds. The solids are dried and hauled by
trucks to the City Of Roxboro Waste Treatment Plant to be Land Applied by Synagrow
or trucked to the Upper Piedmont Environmental Inc. landfill.

Miscellaneous Comments
t c aJTP
,C--'-4'n X.P G'
YES This is a SIMPLE EXPEDITED permit renewal (administrative
renewal with no changes, or only minor changes such as TRC, NH3,
name/ownership changes). Include conventional WTPs in this group.
YES— This is a MORE COMPLEX EXPEDITED permit renewal (includes
Special Conditions (such as EAA, Wastewater Management Plan), 303(d)
listed, toxicity testing, instream monitoring, compliance concerns, phased
limits). Basin Coordinator to make case -by -case decision. -
YES_ This permit CANNOT BE EXPEDITED for one of the following reasons:
• Major Facility (municipal/industrial)
• Minor Municipals with pretreatment program
• Minor Industrials subject to Fed Effluent Guidelines (lb/day limits for BOD, TSS,
etc)
• Limits based on reasonable potential analysis (metals, GW remediation organics)
• Permitted flow > 0.5 MGD (requires full Fact Sheet)
• Permits determined by Basin Coordinator to be outside expedited process
