Subject: Permit Modification / Permitted Flow Increase
NPDES Permit NCO083925
Salem Glen Subdivision WWTP
Davidson County
Dear Mr. Tweed:
The Division of Water Quality (the Division) has reviewed your request to increase permitted flow
(received October 8, 2001) and subsequent supporting Engineering Alternatives Analysis (EAA)
submitted on September 20, 2001 by your consultant (Diehl and Phillips, P.A). This permit
modification has been noticed in newspapers surrounding the Davidson County area and the Division
has received no public comments.
Based on the documents submitted, your request to modify is hereby approved. Attached, please find
change -pages reflecting this modification. Please insert these pages into your existing permit and
discard the old pages. 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 May 9,1994 (or as subsequently amended).
Concerning Discharge Alternatives. The submitted EAA compares discharge alternatives and
concludes that Alternatives 8 and 9 are the most economically viable. The cost difference between
these two alternatives is approximately 6%. While slightly more expensive, Alternative 9 combines
surface discharge to the Yadkin River with seasonal wastewater reuse for golf course irrigation.
Considering relative costs and the more environmentally sound alternative to reuse and conserve
water, the Division shall require Heater Utilities / Salem Glen to pursue Alternative 9.
Please be advised that prior to expanding the subject facility, you must submit a request to the
Division's NPDES Unit for Authorization to Construct (ATC). The request must include all pertinent
plans and specification (see NPDES web site, Instructions for ATC) and must be submitted a
minimum of 90 days prior to beginning construction. Should the Division request additional
information, this review period will be extended.
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable, you have the right to an adjudicatory hearing upon written request within thirty (30)
days after receiving this letter. Your 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 a demand is
made, this permit shall be final and binding. Flwl

Joe, Receiving waters are WS-IV, not WS-V (see below). The draft states WS-IV.
Wastewater resuse on the golf course would be a preferable alternative to continuous
discharge, if in fact not much additional cost, as stated. We will not object to the
issuance of this permit provided proper O & M, and permit limits are consistently met.

Salem Glen Subdivision -- MOD DRAFT Review

From: Joe Corporon <[e-mail]>
To: [e-mail]
John, I received your phone message questioning the need for fecal
monitoring/limit. This is not needed. The previous permit did not have
fecal monitoring because of the very high receiving -stream dilution or
low instream waste concentration (IWC = 0.03 `4). Fecal is calculated
using a dilution factor (331) and Salem Glen's factor, even for the
expanded flow of 0.200 MGD, is -1782 -- over 5 times higher. No
worries. If all else is well, I will add this note to the file as the
sum of your draft comments.

Joe, I'm going to agree with you all on this. If Alternative 9 is only 6% higher cost, then they should go that
route. To reiterate your comments, this would be less surface water discharge and (maybe) could allow for
the decreased use of fertilizers at the facility.
Joe Corporon wrote:
Wes, please find the latest permit modification to increase flow to
0.200 MGD (see attached) -- hard copy to follow. This MOD request was
included in an EAA submitted last September. Recent Level B modeling @
0.200 MGD indicates that "secondary limits" will protect water quality,
therefore the only permit change is a TRC limit (28 ug/L) at the new
flow rate, per Division policy for new and expanding discharges.
This is a major MOD, therefore it will go to Public Notice tomorrow,
17Apr02. You may respond by e-mail or on the hard copy. No rush on your
review. Please contact me if have questions.

Hi Joe,
I am finally. -taking a more detailed look at Salem Glen's flow reduction
request. .-Did we ever find out why they want to increase their plant
capacity to 0.2 mgd? I have their average flows over the last year and
they only average .014 mgd. Seems like a really big jump!
I need to speak with Kim Colson about the data they submitted. They
were supposed to use a years worth of water usage to find the peak month
but they submitted the treatment plant usage.
Thanks, Marie

Thanks for the comments. I did speak with Joe last Friday about it. We
weren't sure why the requests came in at the same time. Joe indicated
they are bounded by land and can't go much further. only thing I could
think of is if they wanted to redesign the lots to be smaller to include
more homes. I will CC you both on an approval letter when I get to
creating one!

Re: Request for Expansion/Modification of NPDES Permit

Heater Utilities, Inc. hereby requests the referenced NPDES permit to be
expanded from .14 MGD to .20 MGD. We further request the additional .06 MGD
be permitted for a combination reuse/discharge, as detailed in Alternative No.
9 in the EAA.
Please contact us or our consulting engineer, John F. Phillips, of Diehl
and Phillips (919-467-9972) if you have any questions regarding the request or

On behalf of Heater Utilities, Inc., Diehl & Phillips, P.A. hereby requests a reduction in the
estimated flow per house utilized for sewer line extensions tributary to the referenced plant. The
request is made pursuant to 16 NCAC 2H.0219(1)(3).
Enclosed are Table 1 and a copy of the September 2000 DMR. Table 1 presents the number of
customers served by the plant for each month between September 2000 and August 2001, the
average flow for each month, and the resulting average flow per house. September 2000 had the
highest average flow per house (182 gallons per day per house). The upper 10% of the daily
listings on the DMR were September 20, 21, and 25 with flows of .015, .017, and .016 MGD,
respectively.
The average flow for these days is .016 MGD, or 222 gallons per day per house for the 72
customers on the system in September 2000. (The flow listed for September 18 is a typographical
error; it should be.0135 MGD to match the flow for the two previous days.)
Heater Utilities, Inc. requests DWQ accept 225 gallons per day per house for all permitted
development not yet tributary to the plant and for all future sewer extension applications. Please
call if you have any questions or require any further information.
Yours very truly,
Diehl & Phillips, P.A.
John F. Phillips, P.E.
