* A modification in operations was made wherein Aqua North Carolina, Inc. (formerly Heater Utilities, Inc.)
has agreed that the two (2) banks of ultraviolet disinfection units will be kept in operation at all times.
Therefore, in the event of any failure in one bank, the second bank will already be on line and will not need the
use of the originally proposed, automatic switching equipment to bring the second unit on line. This matter was
discussed with Mr. Sergei Chemikov (NC DENR) and Ms. Donna Hood (NC DENR) on August 9, 2006 and it
was agreed that, with this operational modification, and the existing back-up chlorine disinfection system, the
automatic switching system is not needed for the UV system to be in substantial conformity with the approved
plans and specifications.

Thanks for getting back to me. I'm sorry it took me a while to respond, but
I needed to discuss this with Heater.
I talked with Tony Parker (Heater) today and he has confirmed that Heater
does want to proceed with the phased installation decribed in my letter
dated 10/16/03.
Therefore, please proceed with your review of the phased installation.
I appreciate your patience with this and apologize for the confusion. If you
have any questions or if I can be of any assistance, please let me know.
Thanks!

I Thurman -
I am so sorry - your message went to the other Susan Wilson (I'm
susan.a.wilson). It causes great confusion but she usually does forward
me messages (sometimes a bit later), so I did finally receive it.
Good question - what is the status on this. I thought it was on hold
as they were still trying to decide what to do. Are they set on trying
to still do the UV system in phases as specified in your letter dated
10/ 16/03? I will proceed forward if that is still the case (I know
there has been much confusion over this because the last thing I
forwarded down to Mooresville they decided to change).
So, give me the word on what final version I am to look at (and if the
one with your letter dated 10/ 16/03 is the correct version) and I'll try
and get to it within the next couple of weeks if not sooner. This
version discusses doing the UV system in phases (and what is to be put
in now would be based on the current flow - not final design flow). It
also has a Heater letter dated 10/14/03 and supporting documentation
from you dated 10/3/03.

Request for Authorization to Construct (ATC)
Proposed UV Disinfection System (Revised) I
Heater Utilities, Inc. -
Country Woods East Subdivision WWTP _
NCO065684 — -
Union County
Dear Ms. Wilson:
As a follow up to our conversation yesterday, I have prepared this letter to serve as an addendum
to the plans and specifications submitted with my letter dated October 6, 2003 for the revised
proposed UV Disinfection System for the existing Country Woods East Subdivision WWTP.
Please accept this as a revision to the request for ATC for these revised design facilities.
This request does not substantially alter the design as submitted, other than to embody the option
to phase the installation of the UV disinfection units to correspond with the phased utilization of
the existing individual package wastewater treatment plants (WWTPs.) Heater is currently
utilizing all of the old portion of the treatment facilities (This being the older package systems that
combine to make a 190,000 gpd system) and one of the three (3) newer treatment trains which are designed
for 160,000 gpd each. This brings the current treatment capacity that is in active use to a total capacity of
000 gp Eventually, when the remaining two (2) 160,000 gpd trains are brought on line, the total
p capacity of 670,000 gpd will be reached. At that time, all three (3) UV disinfection units of the
design submitted will be required to meet the state requirements.
The design submitted specifies the installation of three l,3) Trojan Model TJ 3700K-PTP - isinfecrion units
which are each rated for a flow of 980,000 gpd. The design is or t e units to be Installed in series. With
any one UV unit out of service, the remaining two (2) units have the combined capacity to disinfect a flow
of 1,960,000 gpd which is well in excess of the state required peak design now (2.5 x 670,000 average
daily flow = 1,675,000 gpd.)
Whereas, the treatment capacity currently being utilized is only 350,000 gpd, the required disinfection
capacity can be achieved at this stage with only two (2) of the proposed units. With one of the two (2) units
out of service, the remaining disinfection unit will have the capacity to disinfect a flow of 980,000 gpd
which is well in excess of the state required peak design flow (2.5 x 350,000 average daily flow = 875,000
gpd-)
Therefore, Heater wishes to amend the submitted request to allow for a phased installation of the proposed
UV disinfection system. The first phase will be to install the first two (2) UV disinfection units (UV Bank
IA and UV Bank 1B as shown on sheets 3 and 4 of the plans. All other elements of the design will remain

unchanged with the exception of the natural shifting of the UV outlet chamber and effluent piping to
accommodate the installation of two (2) rather than three (3) units.
The second phase of installation of the UV units will occur prior to utilization of any of the additional
treatment trains. In short, prior to bringing either of the remaining two (2), 160,000 gpd (each) treatment
trains on line, Heater will be required to install the third UV unit. At this point, with the installation of the
third UV unit, Heater will have adequate disinfection for the total facility design and permitted flow
(670,000 gpd.)
Please note that the system will have an auto dialer to alert the operator in case of any emergency
condition and the system will automatically switch to the second or lag bank in the event of any
failure or malfunction in the lead bank. This will be applicable to both the first and second phase
of the installation.

The existing wastewater treatment facilities already have tablet chlorine and dechlorine facilities
that will remain in place and available for use if ever necessary.
I appreciate the assistance you have been throughout the course of this application. If you need
any assistance or if you have any questions or matters we should discuss, I hope that you will call
me (704-788-4455).

Attached are three (3) copies of the plans and specifications for the revised proposed UV
Disinfection System for the existing Country Woods East Subdivision WWTP. Please accept
these documents as our request for ATC for these revised design facilities and our retraction of
the former request,
This is a revised design that is intended to replace the former design and request for ATC that
was submitted with my letter dated June 23, 2003. This revised design includes the installation of
dual effluent pumps that will transfer effluent from the older group of package wastewater
treatment facilities, to combine with the effluent from the newer group of package wastewater
treatment facilities, where the proposed UV system will be located. The combined effluent from
all wastewater treatment facilities will be disinfected in the UV system and then will flow
through the existing outfall to the existing flow junction/measurement box before ultimately
flowing via the existing combined outfall to the stream.
Please note that this revised design employs three (3) banks of UV modules. Any two (2) banks
are more than adequate to disinfect the design peak flow rate (2.5 times daily average.) The
system will have an auto dialer to alert the operator in case of any emergency condition and will
automatically switch to the second or lag bank in the event of any failure or malfunction in the
lead bank.
Country Woods East already has standby power that will insure continued system performance in
the event of a loss of main power supply.
The existing wastewater treatment facilities already have tablet chlorine and dechlorine facilities
that will remain in place and available for use if ever necessary.
I appreciate the assistance you and your staff have been throughout the course of preparing this
design. If you need any assistance or if you have any questions or matters we should discuss, I
hope that you will me (704-788-4455).
