Reduction in Wastewater Flows
Union County
Dear Mr. Shalati:
AT5*,,jA
CDEHNF�
On March 21, 1994, the Division received your request for a reduction in flow rates on all
residences made tributary to both the Crooked Creek Wastewater Treatment Facility and the Dry Fork
Wastewater Treatment Facility. Your letter requested the Division allow the reduction of wastewater flows
from 120 GPD per bedroom as required by the North Carolina Administrative Code to 240 GPD per
household for single family residential units. In support of your request, documentation and water
consumption data was supplied from households located in Union County. On April 7, 1994, after a
preliminary review by the Division, additional information and water consumption data was requested.
This information was provided to the Division on May 31, 1994.
An evaluation has been completed by the Division in accordance with 15A NCAC .0219(1)(3)
using the water consumption data provided from seven (7) different subdivisions. The data submitted
included twelve (12) months of data from November 1992 to October 1993 for all seven (7) subdivisions
and thirty (30) consecutive days of water consumption data from April 21, 1994 to May 20, 1994 for
Hampton Meadows subdivision. From the water consumption data and documentation submitted, the .
Division was able to determine the following:
1. The peak months for the monthly flows submitted were June, July, and August.
2. According to the monthly consumption records submitted for Hampton Meadows subdivision,
the peak month was July, however, daily consumption records were submitted for April 21 to
May 20.
3. Using the monthly water consumption data for the months'of June, July, and August, the
Division eliminated several homes which did not appear to be occupied and therefore did not
consume any water during these months.
4. Upon reviewing the monthly water consumption records for the seven (7) subdivisions and
eliminating several of the homes, the following three (3) highest water consumption rates were
calculated:
.Subdivision Peak Month GPD/Home
Wexford July 1993 324
Wesley Woods June 1993 313 .

The average flow rate for these homes would be 299 GPD per home. However, this flow rate
has not been calculated in accordance with 15A NCAC .0219(1)(3). By using the monthly
flow rates, only an average daily flow rate could be determined for thirty (30) days or thirty-
one (31) days and not the upper 10% of the daily flow rates as required by the regulations.
5. Upon reviewing the daily water consumption records for Hampton Meadows and eliminating
several of the homes that did not consume any water, the following three (3) highest water
consumption rates were calculated:
Pay Number of Homes GPDIHome
Apri125 82 249
Apri130 84 280
May 2 84 239
The average daily flow rate for these homes was calculated to be 256 GPD per home.
However, these daily flows are not from the peak month, therefore this average flow rate could
be significantly higher.
In view of the information submitted and the problems noted above, the Division of Environmental
Management will allow the use of 300 GPD per residence on the following permit applications currently
under review by the Division only:
Project Application Number Number of Lots
Wexford, Section II WQ0008881 14
Hampton Meadows WQ0009077 92
Clover Bend I, II, and III WQ0009078 73
Wesley Woods WQ0009087 120
Meadow Glen Subdivision WQ0009218 72
Sandalwood II and III WQ0009230 142
Sandalwood IV WQ0009231 126
The Division does not feel there has been sufficient evidence submitted to justify granting a flow
reduction for any future wastewater collection systems located in Union County. Although the Division
feels comfortable with the number of homes involved in the study, approximately 420 households, the
monthly water consumption records are not iri accordance with 15A NCAC .0219(1)(3) and the daily water
consumption records for Hampton Meadows were not taken during the peak month which appear to be
either June, July, or August. However, because the above subdivisions have been constructed without a
permit and the wastewater flows are presently tributary to the Union County Public Works Department's
treatment plants, the Division will issue operation permits for these wastewater collection projects.
Please be advised, no future wastewater collection systems permit applications submitted by the
Union County Public Works Department or any wastewater collection system made tributary to the
Crooked Creek Wastewater Treatment Facility and the Dry Fork Wastewater Treatment Facility will be
accepted by the Division until the remaining flows made tributary to the these treatment facilities can be
properly determined. There have been several discussions between the Division and the Union County
Public Works Department on wastewater flows tributary to the treatment facilities. However, according to
Division records, the wastewater flows currently tributary to the treatment facilities are as follows:

age 3
Union County Public Works Department
June 30, 1994
Crooked Creek WWTP (NPDES limit - 1.3 MGD, WWTP Design Flow - 1.0 MGD)
Month (1994) Average Flow (MGD)
January .9366
February .8833
March .9162
April .9127
Dry Fork Wastewater Treatment Facility (WQ0000600 limit - 0.100 MGD)
Month Average Flow (MGD) Maximum Daily Flow (MGD)
December 1993 .185 .335
January 1994 .119 .411
February 1994 .162 .554
March 1994 .185 .704
These flows do not include any wastewater flows permitted by the Division that have not yet been
made tributary to the subject wastewater treatment facilities. Therefore, until these treatment facilities are
upgraded to handle additional flow or the flows are reduced to the treatment facilities, no additional
wastewater collection permit applications will be processed by the Division. In addition, by copy of this
letter, the Union County Building Inspections Department is being informed of the problems that are
associated with these treatment facilities and therefore recommend that no additional homes be made
tributary to the Crooked Creek Wastewater Treatment Facility (NPDES Permit No. NC0069841) and the
Dry Fork Wastewater Treatment Facility (Permit No. WQ0000600).
If you have any questions or comments regarding this matter, please contact Ms. Carolyn D.
McCaskill or Mr. Michael D. Allen at [phone].
