Welcome back! I understand you just got back in the office yesterday from an
approximately one month vacation.
Regarding the Horsepasture River proposed reclassification, the hearing officer is
prepared to provide the following recommendation to the EMC next month for their
approval:
No new discharges will be allowed, and expansions of existing discharges shall be
allowed if:
(A) there is no increase in pollutant loading;
(3) Oxygen Consuming Wastes: Effluent limitations shall be as follows:
mg/l, and NH3-N =.2 mg/.1;
(C) Total Suspended Solids: Discharges of total suspended solids (TSS) shall be
limited to effluent concentrations of*10 mg/1 for trout waters and
other waters;
(D) Nutrients: Where nutrient overenrichment is projected to be a concern, effluent
limitations shall be set for phosphorus or nitrogen, or both.
It is my understanding from our conversation this morning that the June 2008
published public notice for proposed expansion of the Sapphire Valley WWTP was
rescinded, so it will need to be noticed again, and you plan to do so very soon
(within the next few days).
Please let me know, before you notice it again, if such notice will include all of
(A)-(D) above.

FACT SHEET FOR NPDES PERMIT DEVELOPMENT
NPDES Permit NCO022985
INTRODUCTION
The Carolina Water Service Inc. of North Carolina - Fairfield Sapphire Valley Wastewater
Treatment Plant (WWTP), herein called Fairfield WWTP or the permittee, requires a National
Pollutant Discharge Elimination System (NPDES) permit to discharge treated wastewater to
the waters of the state. The permittee's 5-year NPDES permit expires on August 31, 2012 and
the pennittee has requested permit limits modification from the Division of Water Quality.
The request came in at the same time a reclassification proceeding on Horsepasture River.
This Fact Sheet summarizes background information and rationale used by the Division's
NPDES Unit to determine permit limits and monitoring frequencies revision.
FACILITY DESCRIPTION
The Fairfield Sapphire is a privately owned treatment system utilizing an extended aeration
wastewater treatment facilities to treat domestic. The treatment system utilizes a bar screen,
three aeration tanks with integrated clarifiers, and aerobic sludge holding tanks, three chlorine
contact/fine solids settling ponds. Table 1. Summarizes the receiving stream characteristics
and facility description.

The Carolina Water Service Inc. (CWS) has applied for an expansion at the Fairfield
Sapphire W WTP because of additional request for new service from a proposed
development. This facility is currently permitted for 0.6 MGD and requests a permitted flow
of 0.80 MGD.
A level B model was performed on the 0.80 MGD expansion request. Based on the results of
the model, secondary BOD limits will be sufficiently protective of the Trays Island Creek.
However, BOD5 is lowered to 5 mg/L because of on going ORW reclassification proceedings
on the watershed.
BASINWIDE PLAN
The Fairfield Sapphire WWTP discharges into Trays Island Creek in the Savannah River
Basin. The stream classification of this segment of the Trays Island Creek is C.
The Horsepasture River is proposed for reclassification to ORW. The proposal will be
presented to the EMC for approval in November 2008. Fairfield will be required to meet the
new standard if the EMC approves the proposal. The proposal requires all expansion
dischargers to meet the following:
a) there is no increase in pollutant loading;
b) Oxygen Consuming Wastes: Effluent limitations shall be as follows: BOD5 = 5mg/l,
and NH3-N = 2mg/1;
c) Total Suspended Solids: Discharges of TSS shall be limited to 10 mg/I for trout
waters and 20 mg/1 for all other waters;
d) Nutrients: Where nutrient over enrichment is projected to be a concern, effluent
limitations shall be set for phosphorus or nitrogen, or both.
WASTE LOAD ALLOCATION (WLA)
Fairfield Sapphire W WTP was last modeled on March 27, 2006 for a discharge flow of 0.6
MGD and the stream low flows were estimated at that time. Therefore same low flows
estimates at that location were used in the model performed on June 18, 2008.

This is to document our phone conversation on June 30, 2008 that your NPDES
wastewater expansion request has been placed on a brief hold for a reclassification
issue in the Horse pasture River
to be resolved. Hopefully the EMC will reach resolution very soon for the work on
your permit to resume- If you have any question, please feel free to contact me at

Jackson County
Dear Ms. Wilson
Biologists with the North Carolina Wildlife Resources Commission (Commission) received the notice
regarding the proposed NPDES permit modification for Carolina Water Service, Inc. of NC
in Jackson County. The modification involves an increase in wastewater discharge capacity to 0.8 MGD.
Comments from the Commission are provided under provisions of the Fish and Wildlife Coordination
Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d), North Carolina General Statutes (G.S. 113-131 et
seq.), and the North Carolina Administrative Code 15A NCAC 101.0102.
The receiving stream, Trays Island Creek, supports wild brown and rainbow trout. The Horsepasture
River downstream supports the state threatened rosyface chub (Hybopsis rubrifrons) and other rare
species like the Oconee stream crayfish (Cambarus chaugaensis), yellowfin shiner (Notropis lutipinnis),
and redeye bass (Micropterus coosae). Trays Island Creek and the Horse pasture River are being
considered for reclassification by your agency to "C Tr ORW ' and "C Tr ORW +", respectively, because
of excellent biological integrity. For these reasons, it is important that the discharge meet its pollutant
limits and not cause declines of in -stream habitat quality and uses.
Thank you for the opportunity to review and comment on this permit action. If there are any questions
regarding these comments, please contact me at [phone] extension 24.
Sincerely,

We are in receipt of your June 18, 2008 letter and draft permit. We have reviewed the draft and
only have one comment. The proposed residual chlorine after expansion is shown as 28 ug/L. Based on
recent May 1, 2008 letter we have received from the Division, the TRC level will now be set to 50 ug/L as
permits are renewed.
If you should have any questions or need additional information please do not hesitate to call me
at 704-525-7990 x-216 or by email at milashua()uiwater.com.

Dear Ms. Wilson:
On behalf of CWS Systems, Inc. (CWS) we are submitting herewith three (3) copies of our
Preliminary Engineering Report including Economic Alternatives Analysis for a proposed
expansion of the Fairfield Sapphire Wastewater Treatment Plant.
During a previous permit expansion application process in December 2005, the extent of the
requested capacity expansion to 0.8 mgd was limited upon DWQ review to 0.6 mgd due to the
lack of specific requests/commitment for the additional 0.2 mgd of capacity. Since that time CWS
has received additional requests for service as detailed in the attached PER and accordingly we
are applying for an increase in the NPDES permit.
Thank you for your cooperation.
