Polk County
Reference Map: Mill Spring, NC
DWR Quad No. 3578-142
Latitude: 350 21' 0111
Longitude: 82' 12 ' 46"
The dam and impoundment will be located on Britten Creek, a tributary to the Green
River in the Broad River Basin.
The dam safety permit is subject to NCAC 15A 2K.0500 Minimum Stream Flows to
Maintain Aquatic Habitat. The drainage area at the dam is reported to be 4.05 mil. Based on
USGS WSP 2403, the site is located in Hydrologic Area HA10. The average flow is about 6.1
CFS.
Britten Creek lies on the boundary between the piedmont and mountain geographic regions.
It has some characteristics of a piedmont stream, but the stream flow yields of the watershed are
relatively high for a piedmont stream, particularly for a stream with such a small drainage area
(4.05 square miles). The aquatic habitat quality was given a moderate rating based on a Wildlife
Resources Commission (WRC) field investigation and habitat evaluation for the affected reach of
Britten Creek.

Dam Safety Permit Review for Minimum Release
The Pavilion at Britten Creek
Polk County
Based on the field observations of this site, we recommend that a continuous minimum flow
of 2.0 CFS be released at the dam to maintain aquatic habitat and water quality. If inflow to the
impoundment is less than 2.0 CFS, then the minimum release may be reduced to equal inflow. If
any water is withdrawn from the impoundment for irrigation or other offstream use, then the
inflow prior to withdrawal or 2.0 CFS, whichever is less, must be released.
Because this minimum flow is greater than 1.0 CFS, a staff gage shall be installed
downstream of the dam subject to 15A NCAC 2K.0504 (attached). This gage shall be installed
and calibrated according to U.S. Geological Survey procedures, and indicate -the water level
corresponding to a discharge of 2.0 CFS. Plans for this gage shall be submitted to the Division
of Land Resources for approval prior to its installation. Calibration of the gage shall be provided
at least every two years.
Please contact Jim Mead with the Division of Water Resources (DWR) at [phone] if
there are questions about the requirements for the minimum release.
Water withdrawal from the impoundment will be subject to G.S. 143-215.22(G), (H), and
(I); registration of water withdrawals and transfers. Please contact Lisa Routh with DWR, (919)
715-5441, if a withdrawal from the impoundment is planned.

Proposed dam and impoundment on Britten Creek, downstream of SR 1138
in Polk County. (USGS quad Mill Spring, DWR #3582-142)
The reported drainage area is 4.05 mil with average flow
about 6.1 CFS.
The estimated 7Q10 low flow:
(1) 1.0 CFS based on USGS WSP 2403 or
(2) about 1.9 CFS based on nearby Walnut Creek low flow
characteristics
I am requesting your assistance to determine the minimum stream flow
to maintain the aquatic habitat in Britten Creek .
Please let me know ASAP the date when you will know the minimum
release requirement for this proposed project.

Facility requesting NPDES permit for proposed 0.00486 MGD,10M Domestic
wastewater, septic tank/sand %lter discharge to Britten Creek. The permit will be for a 56
bed rehabilation center, that will operate from April thru October. Attached correspondence
shows a proposed impoundment and dam to be developed on Britten Creek. OWR staff
have determined that a continuous minimum flow of 2 cfs be released from the dam to
maintain aquatic habitat and water quality. USGS flow report indicates that at the drainage
area of 4.05 square miles, the summer 7Q10 is approximately 1 cfs. (See accompanying
leekeL
Results of the Level B model indicate that secondary limits of BOD5=30 and
TSS=30 will protect the receiving stream. Limits for fecal coliform of 200/100ml and
Residual Chlorine of 28 µg/l are also needed. Application says that hospital will have
cafeteria. Food service contracted to an offsite vendor. Will recommend OR and Grease
limit are be applied. If ARO deems inapplicable, will remove O&G limits.

MEMORANDUM
FROM: Paul B. Clark
TO: File
SUBJECT: Update on Pavilion International at Britten Creek
DATE: 11/30/95
I realize that some of this information will be redundant depending upon the reader, but I
wanted to copy everyone who is involved with the project. This memo will be in the file. I
have spoken with the following people and important points from each of the conversations
are stated below the person's name.
Jim Leumas(,DEHNR - Land O
They received the dam application. LQ does structural review and routes copies of
application to Division of Water Resources, NCDOT, Wildlife Resources Commission and
one or two other agencies. He recommended I contact Woody Yonts (DWR) regarding
minimum release requirement from proposed dam.
Nood Yonts MELM - DWR)
He conducted hydrological calculations/research on Britten Creek and generated the
following results:
Drainage Area = 4.05 mi2
Average Flow = 6.1 cfs
7Q10 =1.0 cfs (using USGS WSP 2403)
7Q10 =1.9 cfs (using actual data on Walnut Creek - similar creek in vicinity)
W. Yonts submitted this information to others in DWR and Wildlife Resources. The two
agencies agreed on a 2.0 cfs minimum release (as necessary to protect aquatic habitat)
except when inflow into lake is less than 2.0 and in these cases minimum discharge from
lake would equal minimum inflow into lake.
Bill Warren (NC State Construction)
He stressed importance of expediting the permit process. He said that although he did not
agree - the Medical Care Commission was willing to proceed with selling the tax exempt
bonds in December to fund the facility even though all the necessary permits had not been
obtained. Pavillon is politically important because it is a pilot project - a new way to treat
people with substance abuse problems will be used at the facility. The project will be
completed in two phases -1st phase will accomodate 30 people and 2nd phase will
accomodate the remaining 26 people for a total of 56. Proposed lake's future uses include
fire protection and aesthetics. I told him of our concern with lake discharge and he said to
contact applicant and/or engineer.
James Van Hecke (Pavilion International - Applicants
Did not speak with him directly, but he said to contact engineer - Jeff Oden regarding our
concerns with lake discharge.
Jeff Oden (GNA Design Associates, Inc.)
He said he could redesign so that wastewater discharges into stream downstream of dam
and will send a letter confirming this statement.

5. Other Special Items:
PART IV - EVALUATION AND RECOMMENDATIONS
` 1.Wasteload:
Type of waste: 100t Domestic
Summer 7Q10 cfs is 1.0 (=640, 000 gpd) .
Winter 7Q10 cfs is 1.5
Drainage area square miles is 4.05
Instream Waste Concentration is 0.9%
Proposed limits: 30/30 effluent limited
Discharge point should be specified as below the proposed
lake into Britten Creek.
2. The following recommendations are offered:
a. Determine availability of adjacent land or permanent
easement for non -discharging system.
b. The proposed design flow was 4860 gpd. The facility will
allow 2 washing machines for (56 maximum) patients to do
personal laundry. The regs recommend 500 gpd per machine
for self-service laundry. This increases the design flow
to 5860 gpd. Two washers may not be enough for 56
patients, if more are proposed, then add 500 gpd/machine.
c. Install appropriately sized grease trap(s) prior to the
septic tank. Position them in series, far enough away
from the kitchen so as to allow a proper temperature
decrease (if possible, install half -way out of the
ground) .
d. Use a pressure discharge with pump to dose the sand
filter beds.
e. Use laterals on top of the sand filter bed, not a center
splash distribution, as referenced in the proposed
materials.
f. Use a.washed stone - pea gravel cover on top of the sand
filter beds.
g. Provide a maintained road to access the pump station,
septic tank and sand filter beds for routine
maintenance and service.

•
h. Address whether the phase II future expansion of cottages
or single family residences be using conventional (1000
gpd) septic systems? Where will they be located in
relation to Britten Creek, other construction, etc.?
Note: Jeff Oden's letter addressed all of these items to our
satifaction.
The ARO recommends that this permit be issued.
