Aqua North Carolina, Inc. — Diamond Head WWTP

Dear Mr. Melton:
M
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 15, 2007 (or as
subsequently amended).
This final permit includes the following changes from the draft permit sent to you on January 6, 2010
(misdated as January 6, 2009).
• The facility description has been changed to more accurately reflect the wastewater treatment system
as it exists on site. Communications between this office, the Mooresville Regional Office and you
have determined that the condition of the smaller package plant at the site of the Diamond Head
WWTP is such that it no longer exists as a viable wastewater treatment system. Therefore, its
components have been removed from the facility description.
• A term has been added to the Supplement page requiring the permittee to obtain an Authorization to
Construct permit from the Division of Water Quality prior to any expansion of the existing
wastewater treatment facility. The permit retains an ultimate hydraulic capacity and flow discharge
limit of 0.1 MGD.
• New limits pages have been established with flow limits of 0.0731 MGD for the existing treatment
system and 0.1 MGD for an expanded facility (should it be built).

Note to Permit File
NC0074772
Aqua NC — Diamond Head W WTP
3/12/2010
Significant changes were made to the final permit relative to the draft and previous versions of
the NPDES permit.
The system has existed for many years as two package plants (0.0731 MGD & 0.033 MGD)
working in tandem, with shared disinfection, dechlorination and discharge. At the time of the
previous permit renewal (2005/2006) the smaller of the two was described as being shut down
for repairs. This was not seen as a problem since flows to the treatment facility did not approach
the capacity of the larger package plant alone.
Samar Bou-Ghazale of MMO performed the site inspection and prepared the staff report for the
facility's permit renewal. The permit writer didn't recognize the implication of Samar's write-up
of the facility description. The smaller package plant has not been operated for the past 5 years.
Some of its component parts have been removed to be used in other WWTPs. It is a shell of
what it formerly was and no longer can be deemed a WWTP. Its condition is well beyond that of
a "mothballed" plant. Its operation would require reconstruction as opposed to repair. Aqua NC
representatives confirmed this assessment of the situation.
Therefore, reference to the smaller package plant has been removed from the permit. A new
limit page has been prepared that has all the same constituent limits as were found in the
previous permit (because they were established per BPJ because the discharge is into an arm of
Lake Norman), but the flow limit has been set at the design capacity of the existing treatment
system. The permit provides for the facility to expand to the ultimate capacity of 0.1 MGD, but
an AtoC permit will be required before expansion could occur. A second limits page has been
prepared for an expanded facility, with only the flow limit changed.
See Bob Sledge if there are any questions.

Bob,
It will be a good idea. I was thinking to do the same. Also, I looked at the DMR to see the maximum discharge from the
facility and found out that the maximum discharge for the past two years was at half the permitted discharge. However,
in order to play it right we need to go exactly by your suggestion.
"Great mind think alike".
Thanks

Hi Samar,
I'll make the fixes to the permits as you have directed. I'm sorry I missed them the first time around. Regarding
Diamond Head, since the smaller of the two treatment systems is not in use (and it appears its been out of service for a
while), should they be given some form of tiered limits that allows flow only to the capacity of the working system until
they bring the other one on-line? Just a thought ...

Hi Bob,
Happy New year. How R U? I hope everything is well with you.
Please note that the description of the existing facility for permit NCO074772 (Diamond Head) needs to be revised to
reflect the changes mentioned in the Staff Report. There are major changes that needs to be noted.
Also, in permit NCO062481 Mallard Head Condominiums you may need to add in the description of the existing facility a
power generator (if it is not too much trouble)?.
Please call me to discuss the above changes at your convenience.
Have a great day!
