MEMORANDUM
TO: Steve Mauney n
FROM: Carla Sanderson
THROUGH: Trevor Clementsl�L
Steve Tedder KO
SUBJECT: In -stream Assessment
Town of Boonville Wastewater Treatment Plant (NC0020931)
Yadkin County, N.C.
JOC Request No. 87-11
Introduction
An in -stream assessment for the Boonville WWTP has been completed by Techni-
cal Support. The Winston-Salem Regional Office has requested a JOC since the
plant has been unable to meet their wasteflow, BOD5, and TSS final effluent
limits. The Boonville WWTP has applied for an additional 34,400 gallons per day
of domestic and commercial wasteflow. An instream assessment was performed to
assess the impact of the SOC wasteflow.
The Boonville WWTP discharges into an unnamed tributary (UT) to Tanyard
Creek, which is classified "C" waters in the Yadkin river basin. Tanyard Creek
drains approximately 3.7 square miles and, at the location of the Boonville dis-
charge into the UT, the drainage area (DA) is 0.41 square miles with a 7Q10 of
0.075 cfs. The facility's existing NPDES permit limits are as follows:
Wasteflow
0.1
mgd
BOD5
30
mg/1
DO
4
mg/1
TSS
30
mg/l
Fecal Coliform
1000/100ml
pH
6-9
SU
The proposed additional wasteflow is comprised of 45% domestic and 55% com-
mercial sources (car wash and laundromat). Therefore, this analysis addressed
both the .impact on dissolved oxygen in the creek from the domestic components and
from the detergents in the commercial waste. A level-B modeling analysis was
used to assess impacts on the D.O. and a mass balance equation was used to
evaluate MBAS. DEM's WQ standards for settleable solids and turbidity are appro-
priate for this type of commercial waste and were included in the JOC limits.
Analysis
The level-B model was run with the Winston-Salem Regional Office's suggested
limit of 50 mg/l BOD5 for pre-JOC and JOC flows. Since the effluent monitoring
data show the average N113N effluent to be approximately 9 mg/l, this was also
included in the model. These parameters (BOD5 and NON) were entered into the

r+
model as CBOD and NBOD using multipliers of 2.0 for BOD5 and 4.5 for NH3N.
Consequently, the waste inputs for the model were 100 mg/1 CBOD and 40.5 mg/1
NBOD. The pre-JOC wasteflow input to the model was 0.1156 mgd and the JOC waste -
flow was 0.15 mgd. The model results were as follows:
Wasteflow (mgd) 0.1156 0.15
D.O. Minimum (mg/1) 2.20 1.81
Location D.O. Min. (mile) 0.0 0.0
The EMC criteria for granting an SOC/JOC states that with the increased waste -
flow, the D.O. minimum will not be depressed more than an additional 0.5 mg/1 and
the number of miles the D.O. is below 5 mg/1 will not increase more than 0.5
mile. In this case the model predicts the change in the D.O. minimum to be
within the criteria for granting an SOC/JOC and the added wasteflow will not sig-
nificantly affect the existing water quality in the creek.
Recommendations
The recommended JOG limits for the Town of Boonville are as follows:
BOD5
50
mg/l
TSS
50
mg/l
Fecal Coliform
1000/100ml
pH
6-9
SU
MBAS
0.66
mg/l
Settleable Solids
0.10
ml/l
The discharge shall not cause the turbidity of
the receiving waters to exceed 50 NTU.
