Subject: Issuance of NPDES Permit NCO087866
Piedmont Triad Regional Water Authority - John F. Kime WTP
Randolph County
Dear Mr. Flory:
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 15, 2007 (or as
subsequently amended).
This final permit contains the following changes to its terms from, those found in the draft permit sent to
you on August 31, 2011.
• Because the discharge is to the lake, and not to a free -flowing stream (as had been assumed in the
development of previous versions of the permit), the test concentration for the whole effluent
toxicity test has been increased from 23% to 90%.
• Because the discharge is to water supply waters, and effluent data submitted by the facility indicate
reasonable potential for violation of the existing water quality standard, the permit includes a 200
µg/L daily maximum effluent limit for manganese. While it is true that the Division is considering
the removal of the water quality standard for manganese in water supply waters, and that change
would negate the need for a permit limit for the parameter, a final decision on the matter has not
been made as of the date of this letter. Because this is a new limit, the facility is being given a four
year compliance schedule associated with manganese limit in order to allow for planning and
implementing a system to ensure the limit will be met. Because the effective period of this permit
will only extend to August 31, 2016, the short permit cycle will allow both parties to revisit the issue
and make any necessary changes to the schedule at the time of the next permit renewal (at which
time the matter regarding the water quality standard will be much clearer).
• The map has been modified.

• Updates have been made reflecting administrative changes within the permitting agency that have
occurred since the draft permit was prepared.
While it was noted in the renewal application that the water treatment plant uses microfiltration as part
of its water treatment processes, it is agreed that circumstances associated with its source water and the
nature of the body of water receiving the discharge make the Division's permitting strategy for
membrane WTPs not applicable to this facility. Please be advised, however, that should the discharge
exhibit toxicity at the modified concentration level, this decision may be revisited at the time of the next
permit renewal, and monitoring associated with the membrane WTP strategy may be added to future
versions of the permit.
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 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 Resources or any
other Federal, State, or Local governmental permits that may be required.
If you have any questions concerning this permit, please contact Bob Sledge at telephone number (919)

Comments received on Draft Permit?
Yes See notes below
This permit received considerable review when it was originally developed due to concerns regarding
the source/receiving water. Therefore, the existing permit included more details and more monitoring
than most WTPs received at the time of its issuance. However, after the draft was sent to public
notice, some errors were noticed in the historical and draft renewal versions of the permit.
1. The WTP has in the past been considered a conventional WTP for purposes of NPDES permitting.
However it does use microfiltration, which would cause it to be permitted under a different WTP
permitting strategy, combining those requirements with those for a conventional WTP.
2. The permit was originally issued with a 23% concentration for its WET testing. This percentage
was based upon historical 7Q 10 flow (7.7 cfs) at a gaging station on the Deep River downstream of the
discharge point near Randleman. This stream flow value was calculated based upon data collected
prior to construction of the Randleman Dam. The reservoir's tiered release program calls for a
minimum release of 30 cfs from the dam except during drought conditions (20 cfs if reservoir drops to
below 60% full; 10 cfs, it it drops below 30% full). The lake was predicted to operate at over 60% full
90% of the time. All that being said, the discharge from the WTP is to the Muddy Creek arm of the
lake, and not downstream of the release from the dam. As such, the correct concentration for WET
testing should be 90% as opposed to 23%, because the discharge is not to a free flowing portion of the
stream.
This permit languished for years without resolution of these issues. In January 2015, the matter of
permit reissuance was revisited with the staff of the PTRWA. A modified draft permit was shared with
PTRWA that included elements from the strategies for conventional and membrane WTPs, and

changed the WET test concentration to 90%. The PTRWA was given opportunity to review and
comment on the proposed changes.
The PTRWA provided comments which are included in the file. It pointed out that its use of
microfiltration differed greatly from that of most other WTPs in north Carolina, especially in terms of
its source water and the concentrations of elements in the wastewater. It noted that in terms of water
treatment, it is considered a conventional WTP by the Public Water Supply Section. It requested the
permit be prepared pursuant to the Division's conventional WTP permitting strategy only.
The PTRWA stated that although the discharge is to the lake, because of the volume released from the
reservoir, the area near the discharge experienced significant movement and mixing, and therefore the
WET test concentration should be less than 90%, and preferably remain at 23%, at which level the
tests has consistently passed.
These points were considered by the C&EPU Supervisor. It was decided to reissue the permit per the
terms of the conventional permitting strategy, and not include those associated with membrane
treatment, as the facility is essentially a conventional WTP. It was also decided that the WET test
concentration should be modified to 90% because the discharge is to the lake proper, and likely does
not receive significant mixing. The PTRWA was advised that the Division may change its stance
regarding the permitting strategy at the next permit renewal should the facility begin to fail its toxicity
tests at the new concentration.
Last, it was further noted during review that the facility showed reasonable potential to cause the water
quality standard for manganese (200 µg/L in WS waters) to be exceeded, based upon data provided by
the facility. As a result, a 200 µg/L effluent limit was added to the permit for the parameter. However,
because it is a new limit, and because the state is currently considering the removal of the water quality
standard, the limit will not come into effect for 4 years. During that time, the decision regarding the
standard should be finalized and the permit can be modified to reflect that decision.
The PTRWA was advised of these changes to the permit terms and asked to provide any comments. In
a phone conversation occurring on January 23, 2015, a PTRWA representative expressed continued
disagreement regarding the changes to the WET test concentration and fresh concern regarding a
manganese limit, but appeared resigned to the permit being issued as per the modified draft. Beyond
the concern, there was no objection to the permit being finalized.

Subject: Update re NPDES Permitting
Attachments: NCO087866 Limits page - revised 01212015.pdf
Hi Mr. Flory and Mr. Pope,
I wanted to let you know of some updates regarding the structure of the permit. I've got a mixed bag of information to
pass along.
The permit will be issued using the strategy for conventional permits. This will cause the removal of 6 parameters that
were listed on the draft I sent to you on January 12. It will also reduce the monitoring frequencies for a number of
parameters from monthly to quarterly.
Consistent with that strategy, the final version will correct an error I made in trying to craft the permit from competing
strategies, namely, the monitoring frequency for turbidity will be set as weekly instead of 2/month (remaining the same
as in the existing permit).
Also as a part of the conventional permitting strategy, a 200 µg/L daily maximum limit for manganese has been added to
the permit because the discharge is to water supply waters and effluent data show reasonable potential for violation of
the water quality standard . As of today a water quality standard exists for manganese, even though I hear things are
moving closer to having the standard removed. The permit contains a four year compliance schedule for the parameter,
meaning the limit will not take effect until 2019 and there will be a monitoring only requirement until that time. When
the permit is renewed next year, the matter can be revisited and modified based upon actions that take place between
now and then.
The toxicity testing concentration has been changed from 23% to 90% because the discharge is to the lake. It remains a
monitoring only requirement, with no compliance limit.
While it won't be part of the permit, the cover letter will note that should the discharge exhibit toxicity at the new
concentration level, the division may revisit the permitting strategy issue during the renewal of future permits.
While I'm sure some of this information is not what you hoped for, there is some that should be to your liking. I'm sorry
for including some new items at this stage of the process; I'm hoping they will not have any real impact beyond what
they would have per the earlier draft.
I've attached a .pdf copy of a modified limits and monitoring page for your review.
Please call or reply if you have any questions.

RE: Draft Permit NC0087866
Good Morning Mr. Sledge,
I am writing in follow-up to our January 13t" meeting regarding the draft NPDES permit for our wastewater treatment
facility. As discussed during our meeting we have several areas of concern with the draft permit, the first being the
classification of our facility as a Membrane WTP and the second being the reclassification of the discharge point from a
free flowing water body to a reservoir.
With respect to the classification of our facility we believe that we should be classified as a conventional water
treatment plant discharge and be held to the monitoring and discharge requirements for those facilities. While our
facility does incorporate low pressure membrane technology this treatment primarily only serves as an additional
filtration barrier. Membrane treatment was not included at our facility due to high constituent loading, it was included
to provide an additional filtration barrier and in essence serves the same purpose as the dual media filters typically
found on conventional water treatment plants. We do not experience the high dissolved solids and concentrated waste
streams as contemplated in the October 2009 WTP Strategy document you provided. Facilities that would typical fall
into the membrane and ion exchange category contemplated in the WTP Strategy document are those that have been
installed to address brackish water problems or specific contaminant issues such as typically found with groundwater
systems in the eastern part of the State. Our WTP is treating surface water that has the same qualities and constituents
as most other facilities in this area of the State and the membranes do to provide any adverse loadings to the
wastewater discharge, in fact the Department of Environment and Natural Resources Public Water Supply Division
specifically classifies us as a conventional water treatment plant. Given these facts we would therefore request that our
facility be issued a permit consistent with the limits for Conventional Water Treatment Plants.
Additionally I would also like to address the reclassification of our discharge location and the corresponding change in
the WET test from a concentration of 23% to 90%. While the location of our discharge is within Randleman Lake, there
is substantial dilution and movement in the lake, particularly in the area of our wastewater discharge. The discharge is
located just upstream of the confluence of Muddy Creek and the Deep River which causes a substantial amount of
mixing in the area. In addition we are required by permit to maintain a minimum discharge of 30 cfs, we are routinely
higher than this minimum and this is maintained at all times at the dam located just downstream from our wastewater
discharge location. The discharge of over 19 Million Gallons a Day from the reservoir causes a significant downstream
flow and results in further mixing in the area of our discharge. Based on these facts and given that the original discharge
permit was issued for a 23% concentration, having taken in account these circumstances, we believe it would be
appropriate and consistent to maintain the same requirement.
Thank you for your consideration of these facts I hope you will take them into consideration with our final permit.
Sincerely,
Greg Flory

RE: Draft NPDES Permit
After reviewing the NPDES draft I have a couple of questions/requests please:
1) We have the ability to feed fluoride, but we have never fed it at this time. Do we need to monitor it weekly, or
just when we actually feed fluoride?
2) We had discussed over the phone reducing the monitoring on the chronic toxicity to annually or bi-annually. Is
this still a possibility?
Everything else looks great and just as we talked about. We really appreciate all the work you do to get our NPDES

Mai,
I
It was a pleasure talking with you today. Thank you for all your assistance.
I've attached a copy of the draft permit that we'll be sending to you through the mail tomorrow. I hope it looks much
like we discussed. One item I believe I failed to mention was that we've added monitoring for fluoride. The schematic
made it appear this was added to the water prior to it going to the clear well, so the permit assumes it could be in the
backwash that eventually becomes the effluent. If I've erred here, please let me know and I'll fix this in the final
version. If you have questions or concerns, we'll have plenty of time to straighten things out. Feel free to give me a call

Most Commonly Used Expedited Language:
• 303(d) language for Draft/Final Cover Letters: "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 mitigative measures may be required".
• TRC laneuaee for Compliance Level for Cover Letters/Effluent Sheet Footnote: "The Division
shall consider all effluent TRC values reported below 50 µg/L 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 µg/L.."

Piedmont Triad Regional Water Authority would like to request that the chronic toxicity
parameter be removed from our NPDES permit number NC0087866. We have sampled
in October 2010 and January 2011 and passed both tests. We will have sampled an
additional two times (April 2011 and July 2011) before this new permit goes into effect.
We would also like to request that the flow rate restriction be removed.

Sludge Management Plan
The John F. Kime water treatment plant sends the sludge from the super pulsators into
the sludge thickener. Backwash water is sent into the equalization lagoon. The water
decants off the equalization lagoon and is discharged back into Randleman Regional
Reservoir after it is de -chlorinated with sodium bisulfate. The sludge is sent from the
sludge thickener and mixed with polymer then put onto the belt press. It is then put onto
the conveyor and put onto the concrete drying bed. After it finishes drying it is loaded
onto a dump truck and taken to the Montgomery County landfill.
