Instream Assessment for City of Shelby WWTP
NPDES Permit No. NC0024538
Cleveland County
SOC Case No. 89-01
The Technical Support Branch has completed the instream assessment in
response to an SOC request for the City of Shelby. The City is currently
out of compliance with their NPDES permit limits for BOD5, TSS, and whole -
effluent 6xicity. The SOC request is to allow time for the construction of
additional treatment facilities, in addition to the relocation of the Shelby
WWTP's discharge point from Hickory Creek to the First Broad River. An
instream 'assessment was done for both discharge locations so that during the
interim period of construction the City would have SOC effluent limits that
would be applicable at either outf all . Also, the City did not indicate a
specific amount of wasteflow to be added during the life of the SOC, so a
determination was made for the maximum increase in flow that would be
allowed and not violate the EMC approved 67(b) criteria.
The impact of the Shelby WWTP's wasteflow on dissolved oxygen (DO) lev-
els in both Hickory Creek and First Broad River was evaluated using Techni-
cal Support's Level B modeling framework. The results of this analysis
indicate that the wasteflow at both discharge points could increase by 2.27
MGD to a total of 5.5 MGD with interim limits of 45 mg/1 of BOD5 and 4 mg/1
of DO, and not cause a significant impact of more than 0.5 mg/1 of DO sag or
extend the streamlength predicted to violate the DO standard by more than
0.5 miles.
It is recommended that additions of wastewater under the Order be spe-
cifically limited to domestic sources or non -process wastewater given the
City's severe noncompliance with whole -effluent toxicity limits. We also
recommend that the facility continue to perform quarterly chronic toxicity
monitoring of its effluent. Technical Support has received updated flow
information for both Hickory Creek and the First Broad River and instream
waste concentrations (IWC) of 69% and 12%, respectively, should be used.

Discussion
The Shelby WWTP is a 6.0 MGD treatment system that currently discharges
into Hickory Creek in the Broad River Basin. U.S.G.S flow data recently
obtained indicates the summer 7Q10 flow at the discharge point is 4.1 cfs,
with a drainage area of 19 square miles and an average flow of 26 cfs. Hick-
ory Creek has a stream classification of C and flows approximately 0.2 miles
before entering the First Broad River. The new discharge point for the WWTP
will be into the much larger First Broad River, less than 100 feet above its
confluence with Hickory Creek. The summer 7Q10 at the proposed discharge
point increases to 70 cfs, with an average flow of 371 cfs. The drainage
area of the First Broad River is 267 square miles, approximately 14 times
larger than the Hickory Creek site.
Facility compliance data for May, 1988 through April, 1989 report the
average monthly wasteflow as 3.23 MGD (Pre-SOC flow). As previously men-
tioned, there was no specific amount -of wasteflow requested by the SOC. The
post-SOC flow was determined by gradually increasing the amount of wasteflow
until the 67(b) criteria was violated or until the design capacity was
reached.
A Level B modeling analysis was used to assess the impact of the Shelby
WWTP discharge on dissolved oxygen -in both Hickory Creek and the First Broad
River. The waste input for CBOD reflected the Asheville Regional Office's
recommended BOD5 limit of 45 mg/1; this yields a CBOD input of 90 mg/1
(using a CBOD/BOD5 multiplier of 2.0 for facilities with >10% of their
wasteflowlhavingindustrial constituency). A waste input for NBOD was
determined by using the 1988 maximum summertime NH3 value of 14.44 mg/1;
this yields a NBOD input of 65 mg/1 (using a NBOD/NH3 multiplier of 4.5).
The recommended effluent DO value of 4 mg/1 was also included in the model
input.
At the Hickory Creek discharge point, a model was run at 3,.23 MGD and
the recommended SOC limits. The model results predicted a DO minimum of 4.9
mg/1 to occur approximately 0.17 miles below the outfall at the mouth of
Hickory Creek. Incremental increases in the wasteflow determined that an
additional 2.27 MGD (a post-SOC flow of 5.50 MGD) could be accepted at this
discharge point resulting in a DO minimum of 4.4 mg/1 at milepoint 0.17.
With a difference of 0.5 mg/1 between DO minimums for the pre-SOC flow and
post-SOC flow, this constitutes an acceptable range and meets the 67(b)
criteria.'! Complete model results for the existing discharge at Hickory
Creek are presented in Table 1.
' Models were also run at the proposed First Broad River discharge point
using the same wasteflows of 3.23 MGD and 5.50 MGD from the Hickory Creek
model. Instream DO levels did not violate the standard in the First Broad
models runs, with DO minimums of 7.0 mg/1 and 6.5 mg/1 respectively. This
is a difference of 0.5 mg/1 and demonstrates an acceptable depression of the
instream DO level per 67(b) criteria. Table 2 contains the model results
for the proposed First Broad River discharge point.
A review of Shelby's whole -effluent toxicity testing results indicates
five (5) failures during 1987, three (3) failures during 1988, and a failure
to submit test results in 1989. Given this poor performance level, the
Order should include the continuation of toxicity testing and specifically

limit the addition of wastewater to domestic or non -process sources.
Recommendation
Based on Level B model results, Technical Support recommends approval of
up to 2.27 MGD additional wasteflow from domestic sources only for the
Shelby WWTP. This wasteflow increase will be applicable at both the Hickory
Creek and First Broad River discharge points with the SOC limits for BODS,
TSS, DO, fecal coliform and pH as cited by the Asheville Regional Office.
The continuation of quarterly chronic whole -effluent toxicity testing using
an IWC of 69% for the Hickory Creek outfall or an IWC of 12% for the First
Broad River outfall is recommended.

Ann B. Orr
Regional Manager
Please find attached an in -stream assessment request for the City
of Shelby; attached to the request form are (1) 2 years of MP
Printouts, (2) copies of the JOC schedule and limitations pages, and
(3) a topo map with both discharge locations marked. Shelby's JOC
requires relocation of the outfall from Hickory Creek to the First
Broad River; that is the reason for two discharge locations and the
request that maximum flow allocations be determined for both locations.
The Shelby !JOC has been sent to the City's attorney for filing and will
soon be in effect. Shelby desires to add additional domestic flow as
soon as possible. Please run the instream assessment to determine the
maximum additional domestic flow which the City may add at both
discharge locations under JOC.
Thank -you for your assistance. If additional information is
required, please contact me.
