Instream Assessment for SOC 67(b) Request
Town of Bakersville WWTP
NPDES Permit No. NC0025461
Mitchell County
Summary and Recommendation
The NPDES Unit has reviewed the request for an instream assessment for the
Bakersville WWTP. The Town is requesting a Special Order of Consent (SOC) during
improvements to the wastewater treatment plant. The existing design flow is 0.075
MGD. Two final SOC flows of 0.150 MGD and 0.200 MGD have been requested, which
includes 0.01375 MGD of domestic wastewater with the remaining flow being excess
inflow/infiltration (I/I) occurring at the plant. Additional SOC limits requested are BOD5
= 45 mg/I, TSS = 45. mg/l, and fecal coliform = 400/100mI.
The results of the Level B model analysis indicated that according to the EMC
67(b) criteria, the predicted dissolved oxygen (DO) concentration in Cane Creek was not
significantly affected by the additional flow and higher BOD5 levels proposed. The
EMC 67(b) criteria states that the discharge will not increase the DO minimum by more
than 0.5 mg/1 or will not extend the stream length of the DO minimum by more than 0.5
miles. This criterion was not violated with the addition of 58,000 GPD and 108,000 GPD
at the higher BOD5 limits. Our analysis determined that the stream could assimilate the
additional flow and loading as requested.
Background
The Town of Bakersville discharges into Cane Creek, a tributary to the North Toe
River in the French Broad River Basin and has a stream classification of C Trout. The
stream is not listed on the North Carolina 303(d) Degraded List. Cane Creek drains
approximately 22.4 square miles at the discharge point. The estimated summer 7Q10
flow (1989) with an average flow of 3.6 cfs.
Instream Assessment for Bakersville SOC
Page 2
A review of compliance evaluation data shows that for the past year, Bakersville
has consistently violated the limit for wasteflow. From June 1998 through May 1999, the
monthly wasteflow limit was exceeded in ten of twelve months. In addition, there were
contraventions of the fecal coliform (3), BOD5 and TSS limits.
Analysis and Discussion
An instream assessment was performed using the Level B model framework. The
current design flow of the Bakersville WWTP is 0.075 MGD. The yearly average
wasteflow from June 1998 to May 1999 of 0.0922 is listed as the pre-SOC flow. It
should be noted that monthly average flows have been much higher than 0.0922 MGD as
a result of inflow/infiltration. The post SOC flows used in this analysis were 0.150 MGD
and 0.200 MGD, which allows for the additional 13,750 GPD of domestic flow plus any
additional inflow and infiltration that may occur during the SOC. The monthly average
effluent limits recommended for the SOC are 45 mg/1 of BOD5 and 45 mg/1 of TSS.
Three models were run at the flows of 0.0922 MGD, 0.150 MGD and 0.200
MGD. Waste inputs into the models included 60 mg/1 of CBOD (45 mg/1 of BOD5 *
1.5) and 90 mg/I of NBOD (NH3 value of 20 mg/1* 4.5). The models results predict DO
minimums of 7.43 mg/I at 0.0922 MGD, 7.25 mg/I at 0.150 MGD, and 7.11 mgll at 0.200
MGD. The differences between the DO minimum at the pre-SOC flow of 0.0922 MGD,
and the two other flows are 0.18 mg/1 and 0.32 mg/1, respectively. These differences do
not demonstrate a significant depression of the instream DO level per 67(b) criteria.
Regarding the recommended SOC fecal coliform limit of 400/100m1, it is
recommended that this SOC limit be approved since this is also the permitted daily
maximum limit for fecal.
Recommendation
Based on the model results, the NPDES Unit recommends approval of the 13,750
GPD of domestic waste, allowing for additional excess inflow/infiltration for the
Bakersville WWTP. Model results indicate that a final SOC flow of 0.150 MGD or
0.200 MGD and the SOC limits of 45 mg/I BOD5 (mo. avg.); 60 mg/I BOD5 (daily max.)
will meet the 67(b) criteria. We also recommend approval of the SOC limits for TSS
limit of 45 mg/1 (mo. avg.); 60 mg/1 of TSS (daily max.) and fecal coliform of 400/100m1.
It is recommended that the other permitted limitations remain the same as in the existing
NPDES permit.

ARO requesting instream assessment for SOC for Bakersville. SOC limits are for BOD5,
TSS, fecal coliform and flow.
SOC limits requested: BOD5 = 45 mg/I (mo. avg.) and 60 (da. max.)
TSS = 45 mg/1 (mo. avg.) and 60 (da. max.)
Fecal coliform = 400/100m1
Flow = 0.150 MGD and 0.200 MGD
( only 13,750 GPD of this flow will be domestic ww, the remaining flow will be allowed
for inflow/infiltration, which is the major reason for facility's noncompliance with
permitted flow limit.)
Model inputs: BOD5 at 45 mg/1 * 1.5 multiplier = 67.5 mg/1 CBOD
NH3 at 20 mg/1 * 4.5 multiplier = 90 mg/I NBOD
Qws of 1) 0.0922 MGD, average Qw from June 1998 thru May 1999
2) SOC flow limit of 0.150 MGD and 3) SOC flow limit of 0.200 MGD
Model was run to compare predicted instream DO minimum. Cannot violate the criteria
of 0.5 mg/1 difference in DO min. between initial flow of 0.0922 MGD and SOC flows.
Also cannot exceed the zone of degradation greater than 0.5 mg/1. Model results indicate
that all criterion are met. See memo for specific DO min., etc.
