The Harbour Water Treatment Plant- Well #4
Iredell County
Dear Mr. Haas:
In accordance with the application for discharge permit received on December 2, 1998, the
Division is forwarding herewith the subject state -NPDES permit. In addition, authorization is
concurrently granted for the construction of a septic tank for solids removal. Specific conditions and
limitations are listed below.
NPDES Permit Issuance
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 December 6, 1983.
There is one change between the DRAFT permit and this FINAL permit. Due to the intermittent
flow in the receiving stormwater ditch, compliance monitoring for turbidity has been changed from
instream sampling to effluent sampling, with an effluent limit of 50 NTU.
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,Post Office Drawer 27447, Raleigh,North Carolina 27611-7447. Unless such a demand is
made, this permit shall be final and binding.
Please take notice that this permit is not transferable except after notice to the Division of Water
Quality. Part II, E.4. addresses the requirements to be followed in case of change in ownership or control
of this discharge. The Division of Water Quality may require modification or revocation and reissuance
of the permit.

Project Notes
Summary. This is a new applicant for a water treatment plant(WTP)filter backwash discharge to an
unnamed trib to Lake Norman. The applicant proposes to construct a community drinking water well
with cation exchange resin water softeners. Backwash from the filters(estimated at 3000 gpd)will be
discharged to a dry stormwater channel and travel approx.900-feet before entering Lake Norman,which
is oligotrophic and not listed in the 1998 303(d) list. For treatment of backwash discharge,applicant
proposes to construct two septic tanks in series to trap particulates.
Proposed Effluent Limits. Effluent limits were based on revised 1992 WTP NPDES Policy memo.
Since Q<5,000 gpd,quarterly monitoring is appropriate for all parameters. TRC monitoring added since
GW is disinfected with chlorine. Chloride monitoring added since they will perform brine recharge of
water softener.
EAA Review. Based on recent NPDES review,the potential alternatives for WTP backwash discharges
are extremely limited. The applicant stated that a POTW is approx. 5 miles away;residences in
subdivision are on individual septic systems. The permittees soil scientist stated that land
application/reuse options are not feasible due to high sodium content. Non-Discharge Unit(Kim Colson)
concurred that the high sodium content would nullify a land application option. Therefore NPDES is
recommending issuance of discharge permit.
Mooresville Region. MRO staff report dated 2/3/99 recommended that permit be issued.

PART IV-EVALUATION AND RECOMMENDATIONS
The applicant proposes to construct a community drinking water well with cation
exchange resin water softeners. The filters will backwash intermittently and discharge into a
stormwater channel that eventually drains to Lake Norman. The filters are designed to remove
CaCO3 (hardness) from the well water.
Pending a final review by the NPDES Permitting Unit, it is recommended that a Permit
be issued.

Dear Mr. Weaver:
b-ti
Three (3) copies of an executed Short Form D and check for$400.00 are enclosed for a proposed
�� discharge of backwash water for Thome PQg t. This application package was returned to us due to the
use of an outdated form. For your ease of reference, a copy of your October 9th review letter is
enclosed.
The Point and The Harbour are adjoining subdivisions developed by Crescent Resources Inc., and
are served by a water system owned and operated by Carolina Water Service. A permit (NPDES NC
0084565) has been previously issued for discharge of softener backwash for the first well system
constructed in the Harbour. Since the softeners use a cation exchange resin for hardness removal,
there is no contamination in the backwash and the NPDES permit was issued without a requirement
for alternative analysis. In essence, this type of system is a filtering process similar to the same type
process as a swimming pool backwash, except only clean well water is filtered, thus there would seem
to be no basis for concern as to adverse water quality impacts. u:1 1
We respectfully request a re-consideration in regard to this requirement for alternative analysis as a �r`l?�}N-
/bob low priority, no contamination discharge. �'
c W
We are also enclosing an application and processing fee of$400.00, and three (3) sets of plans for
a second discharge point for a water softener discharge for new Well Number 4 for the Harbour.
Although we are filing for a new permit for The Point, it would be preferable and seems logical, if
possible,to include this system as a third point of discharge within the overall Harbour/Point Water
System, since it will be owned in it's entirety by Carolina Water Service, is contiguous. and since it IT
is possible that additional discharge points may be requested in the future due to the distances
separating the wells.

Re: The Rsilnt Well System
Iredell County
LDESI P.N. 88055
(Return#2016)
Dear Mr. Weaver:
Three (3) copies of an executed Short Form D and check for $400.00 are enclosed for a proposed
discharge of backwash water forThre P t. This application package was returned to us due to the
use of an outdated form. For your ease of reference, a copy of your October 9th review letter is
enclosed.
The Point and The Harbour are adjoining subdivisions developed by Crescent Resources Inc., and
are served by a water system owned and operated by Carolina Water Service. A permit (NPDES NC
0084565) has been previously issued for discharge of softener backwash for the first well system
constructed in the Harbour. Since the softeners use a cation exchange resin for hardness removal,
there is no contamination in the backwash and the NPDES permit was issued without a requirement
for alternative analysis. In essence, this type of system is a filtering process similar to the same type
process as a swimming pool backwash, except only clean well water is filtered, thus there would seem
to be no basis for concern as to adverse water quality impacts.
We respectfully request a re-consideration in regard to this requirement for alternative analysis as a
Ob low priority, no contamination discharge.
We are also enclosing an application and processing fee of$400.00, and three (3) sets of plans for
a second discharge point for a water softener discharge for new Well Number 4 for the Harbour.
Although we are filing for a new permit for The Point, it would be preferable and seems logical, if
possible, to include this system as a third point of discharge within the overall Harbour/Point Water
System, since it will be owned in it's entirety by Carolina Water Service, is contiguous, and since it
is possible that additional discharge points may be requested in the future due to the distances
separating the wells.
1700 East Blvd., Charlotte, NC 28203 • Telephone:[phone] • Fax: [phone]

We appreciate your cooperation, and hope you will let us know if the decision is to require the
analysis as soon as possible.
Thank you.

LDESI P.N. 88055
Dear Tom:
My sincere thanks for your e-mail and your call. We very much appreciate your efforts in resolving
how to handle a well softener backwash discharge.
D��f ) In response to your letter, I have enclosed a map depicting the location of existing public sewer
ff (Town of Mooresville), which is approximately five (5)miles from The Point well building. This
distance makes this alternative economically unfeasible.
Regarding possible reuse as a non-discharge option,I have investigated the operation ofthe softeners
with Global Water Conditioning,the manufacturers of the equipment,and discussed this option with
Toney Jacobs, the soil scientist for The Point project. (As a matter of information, The Point
residences will all be served by individual septic systems.)
The softener backwash is approximately 3,000 gallons, and occurs once a day. There are two (2)
softeners,each of which has full rated capacity,thus they will alternate every other day backwashing.
Backwash is with a brine solution which uses 325 pounds of salt per backwash,of which 213 pounds
attaches to the media to replace the hardness(Calcium Chloride). Based on this concentration,even
with an extremely low loading rate,there would be a sodium buildup over time that would severely
inhibit nlrnt ornwth Thug Tnnev wrnilrl nr.t rern,nn,Pn1 a land application system for the backwash
water.
G.moss\dnusbanid i fj012299.wpd
1700 East Blvd.,Charlotte,NC 28203 • Telephone:[phone] • Fax:[phone]

88055
We are requesting that there be two (2) 1,500 gallons septic tanks in series, approved to trap any
particulates in the backwash stream. Plans are enclosed.
We understand the Division's decision on maintaining separate discharge points for each of the well
buildings, and Carolina Water Service has no objection to this decision.
Again, thank you for your cooperation. Please let me know if additional information or
documentation is required.
Very y o s,
Dale C. Ste .E.
