Bethany School, NC0037001
Rockingham County
Dear Mr. Holcomb,
I am writing in response to the October 9, 1996 letter from Mr. W. Max Frazier, PE,
concerning a proposed expansion and relocation for the Monroeton and Bethany Schools'
waste water discharge. The proposal includes one site for the Monroeton School and two
sites for the Bethany School. I will outline each proposal separately.
The Monroeton School currently discharges to an unnamed tributary to Troublesome Creek
which has low flow statistics that require an alternatives analysis for the current discharge.
The proposed relocation for this discharge is to a swamp -like segment of the Haw River
which is classified as C - NSW. This segment of the Haw River generally offers little
assimilative capacity for oxygen -consuming wastes due to the low stream flows, low
reaeration rates, and high sediment oxygen demand. To protect the dissolved oxygen stream
standard of 5 mg/1 and allow for the allocation of the limited assimilative capacity in this
waterbody segment, limits no less stringent than 15 mg/1 of BOD5 and 4 mg/1 NH3-N are
recommended for new and expanding discharges to the Haw River and its tributaries upstream
of SR 2711.
In 1983, the need for watershed -wide nutrient management for the Jordan Reservior
prompted the development of a Nutrient Sensitive Water (NSW) strategy which requires
effluent total phosphorus limits of 2.0 mg/1 for all new or expanding discharges.
The following outlines our current recommendations for the Monroeton School,
NC0036994 expansion and relocation to the Haw River:

BOD5 (mg/1):
NH3-N (mg/1):

The Bethany School currently discharges to an unnamed tributary to Huffines Mill Creek
which has low flow statistics that require an alternatives analysis for the current discharge.
Two proposed sites for this discharge to relocate were requested. The first was to
Troublesome Creek which is classified as WS-III NSW CA. The proposed location, (at the
bridge for SR 2351) has a positive flow during low flow periods, therefore a modeling
analysis was performed and secondary treatment is predicted to protect the receiving waters
dissolved oxygen standard of 5.0 mg/1. As with the Haw River site, a 2.0 mg/1 total
phosphorus limit would be required.
The following outlines our current recommendations for the Bethany School, NC0037001
expansion and relocation to Troublesome Creek:
Flow (mgd):
BOD5 (mg/1):

The second site proposed for Bethany School was to Huffines Mill Creek which does not
have sufficient drainage to meet the minimum stream flow criterion for discharge. A change in
the proposed site to SR 2359, (downstream from the original request) has a drainage area
large enough to sustain positive flow during predicted low flow periods. This proposed
relocation has a positive flow during low flow periods, therefore a modeling analysis was
performed and advanced secondary treatment is predicted to protect the receiving waters
dissolved oxygen standard of 5.0 mg/l. Unhke the Haw River discharge, no nutrient limits
would be required at this discharge location as it is in the Roanoke River Basin which is not
showing signs of nutrient problems.

expansion and relocation to the Huffines Mill Creek:

Under current DWQ procedure, dechlorrnatron and chlorine limits are recommended for all
new or expanding dischargers proposing the use of chlorine for disinfection. An acceptable
level of residual chlorine in all of the proposed discharges is 28 µg/1 for protection against
acute toxicity. The process of chlorination / dechlorination or ultra violet radiation may allow
the facility to comply with the total residual chlorine limit.

Rockingham County Schools Speculative Limits
NC0036994 & NC0037001 Rockingham County
Please be advised that response to a speculative request does not guarantee that the Division
will issue an NPDES permit to discharge treated wastewater. In accordance with the North
Carolina General Statutes, the practicable waste treatment and disposal alternative with the
least adverse impact on the environment is required to be implemented. Nondischarge
alternatives, such as spray irrigation or connection to a regional treatment and disposal system,
are considered to be environmentally preferable to a discharge. Therefore, prior to submittal
of an NPDES application, a detailed alternatives analysis must be prepared to assure that the
environmentally sound alternative was selected from the reasonable cost effective options. In
order to receive final permit limits, a formal application indicating the proposed WWTP design
capacity and a justification for the facility will have to be submitted to the Division's Permits
and Engineering Unit.
The final NPDES effluent limitations will be determined after a formal permit application
has been submitted to the Division of Water Quality. If there are any additional questions
concerning this matter, please feel free to contact Farrell Keough at [phone], extension
510 or me at extension 519.

The proposed site for relocation is to a swamp -like segment of the Haw River classified as C - NSW.
The Basin Plan recommends an Alternative Analysis and/or 15 BOD5 / 4 NH3-N for this area of the
Haw River, (section 6.3.5). A 2 0 mg/1 Total Phosphorus limit is also required for all new or
expanding discharges to this area, (section 6 4 2)
No model will be run for proposed site for two reasons the high s7Q10 will result in less stringent
limits than those outlined by the Basm Plan and the proposed discharge is to a swamp system that will
not be well portrayed by the Level B model.

• Two proposed sites for relocation were requested; Huffines Mill Creek and Troublesome Cre„�
Huffines Mill Creek 03-02-03
The proposed site had a drainage area that was less than the minimum required for an HA 9
discharge. If the discharge was located further downstream at SR 2359 the flow statistics would
be positve. A model was run at this site to prevent the need for the consultant to re -request a
speculative on this waterbody. The flow statistics required a 14 mg/1 NH3-N, and the model
indicated that Advanced Secondary Limits would protect.
The Huffines Mill Creek site is located in the Roanoke River Basin and would not have the nutrient
or conventional parameters limits that the Cape Fear discharges would.
Troublesome Creek 03-06-01
The Toublesome Creek, [WS - III NSW CA] proposed site did have a positive flow and the
model was run. The model indicated Secondary Limits would protect.
The Troublesome Creek proposed site would have the same nutrient removal requirments that the
Haw River site above would have, (i.e. 2 0 mg/1 Total Phosphorus).
