Design Flow Modification
NPDES Permit No. NC0074756, Stanly County
On May 31st I responded to a request regarding additional wasteflows for the Badin
Wastewater Treatment Plant. In the response I gave preliminary limits for the waste -
flows of 0.4 MGD, 0.5 MGD, and 0.6 MGD. Subsequently, the wasteflow for the Badin
facility was decided to be 0.55 MGD and another analysis was performed to determine
the effluent limits applicable for this wasteflow. In the evaluation for this waste -
flow, some descrepencies were found in the initial allocation. Therefore, a revised
Level B modeling analysis was performed to establish speculative limits for the
increased flow of 0.55 MGD. The Badin Wastewater Treatment Plant has two possible
sets of limits for summer from which to choose. The results are as follows:
Wasteflow (MGD)
BOD5 (mg/l)
NH3N (mg/1)
D.O. (mg/1)
TSS (mg/1)
Fecal Coliform 0/1000 ml)

The existing permitted flow for the Badin Facility is 0.18 MGD. Therefore, the above
listed wasteflow and corresponding effluent limits are not final. Final limits can
only be obtained by submitting an NPDES permit modification request.
If you have any further questions regarding this matter, please contact me at

MEMORANDUM {� l
To: Allen Wahab
From: Carla Sanderson

Subject: Greater Badin Wastewater and Sewer District
A. T. Justification - Project No. C370522-01
NPDES Permit No. NC0074756,'Stanly County
Increase Design Flow
This memo•is in response:to your memo dated May 16, 1989,
regarding additional wasteflow for the proposed Badin WWTP dis-
charge. The request for additional flow (0.4 MGD - 0.6 MGD) has
been evaluated using the same Level B analysis as previously used
for the original requested flow (0.18 MGD). The results are as
follows:

* limits apply to both flows 0.4 MGD and 0.5 MGD
As you will note, the limits for the increased design waste -
flows of 0.4 MGD and 0.5 MGD are the same limits as given for
0.18 MGD. The minimum dissolved oxygen concentration decreases
in the model when the wasteflow is increased with these limits,
but still protects to the standard. Also please note that an
increase in design capacity to 0.6 MGD results in a reduction of
the NH3-N limit of 1 mg/l during the summer and a 1 mg/l increase
in the DO limit during the winter.
The existing permitted flow for the Badin Facility is 0.18
MGD. Therefore, the above listed wasteflows and corresponding
effluent limits are not final. Final limits can only be obtained
by submitting an NPDES permit modification request.
i,

If you have any further questions regarding this matter,
please contact me at 733-5083, ext. 514.

Subject:
201 Facilities Plan
Badin Area Amendment
Project No. C370522-01
I have reviewed the 201 Facilities Plan for the Greater Badin Water and Sewer
District. The site for the new WWTP on Little Mountain Creek and the abandonment
of the Badin West facility is consistent with our Wasteload Allocation records.
However, no mention is made of the wasteload allocation and the resulting limits.
Below are the effluent limits and the monitoring requirements developed in the
wastel.oad allocation. The following should be included in the 201 Facilities
Plan:
SUMMER

"Recommend instream monitoring for D.O., Temperature, Conductivity, and Fecal
Coli.form on a weekly basis for the summer (April through October) and on a monthly
basis for the winter (November through March)"
If you have any further questions, please contact David Vogt or myself.
