Subject: comments on cwmtf ww & reuse proposals
Paul - Here are comments on several more of the WW project proposals. — Mike T
2010-507 Town of Briscoe, WWTP Upgrades
The Town proposes to construct an automatic bar screen and a 60'-diameter clarifier and to rehabilitate the sludge
drying bed retaining walls at its existing WWTP.
The proposed improvements are based on recommendations from a recent DWQ compliance inspection. They address
specific deficiencies found at the treatment plant and would likely improve the plant's performance. NPDES defers to
the Mooresville Regional Office as to whether this is the preferred course of action for the plant.
2010-522 Hoke County, 'Clean Burn Fuels' Reuse
Hoke County proposes to construct a tertiary treatment train to generate 1.0 MGD of reuse water, and a reuse pump
station and 12" force main for distribution to Clean Burn Fuels (an ethanol production plant, under construction). The
reuse train would be associated with a larger regional WWTP, presumably funded and constructed separately.
The status and schedule of the project is unclear. The County's application (p.11, item 7.2.6) indicates that the reuse
project will be permitted at the same time as the larger WWTP; however, the NPDES unit has not received a permit
application. Item 7.3.1 indicates that the design is approx. 5% complete and expected to be completed by October 2009.
NPDES is neutral on this proposal but questions whether CWMTF monies can be used to provide financial support for a
private project.
2010-534 Town of Oak Island, Reuse System Extension
The Town proposes to construct 13,000 lineal feet of reuse force main.
The Town has a substantial reuse system already in place. It apparently proposes to improve the system by (1)
connecting the mainland and island portions of its system and (2) extend its distribution system to reach several other
key users.
NPDES generally supports reuse of treated wastewater and has no objection to this proposal.
2010-545 Town of5tantonsburg, WWTP Upgrade
The Town proposes to construct Phase 1 of a WWTP upgrade and expansion. The project includes installation of grit
removal, a new clarifier and RAS/WAS pump station, UV disinfection, and equalization tank. It will not increase the
treatment capacity of the existing plant, which would be part of Phases 2 and 3.
The Town's WWTP has had a poor compliance history since 2003, with repeat violations of permit limits for fecal
coliform, total residual chlorine, and total suspended residue. Serious I&I problems in the Town's collection system are
well documented and, due to the resulting high flow rates at the plant, the Town is under a sewer connection
moratorium. The I&I deficiencies have been noted in two engineering reports prepared for the Town and one regional
wastewater study.

NPDES believes that the proposed improvements would be worthwhile but prefers that the Town first address the more
significant I&I problems.

Project Narrative
Requested Funds
The Town of Biscoe is applying for $687,000 in funds from the Clean
Water Management Trust Fund for Wastewater Infrastructure. The
Town plans to match this with their own $213,000 which is a 25% total
share of the project cost. This request comes with great urgency; all
the infrastructure enhancements have been suggested by the Division
of Water Quality to assist the Town in reducing violations and
potential plant failures.
Scope of Work
The Wastewater Infrastructure Grant is being perused with 3 main
investments:
1. The installation of a 60' Diameter Clarifier and Valves
2. The installation of an Automatic Step -Bar Screen and Valves
.3. The rehabilitation of the Drying Beds
The work undertaken by the Town of Biscoe will include attending
construction and design meetings, bidding the three components,
supervising the contractors, and providing information about the
WWTP. The project components will be considered complete upon
final inspection by our engineer and final payment to contractor.
Project Description and Need
The Biscoe Wastewater Treatment Plant was originally designed as a
single path lagoon plant. When it was constructed over 34 years ago,
shutoff valves where not designed into the system. There is currently
no way to close one of the aeration basins without using a temporary
plug. There is no way to stop flow to the clarifier from the basins.
When closing out the lagoon, as part of the last grant, the Town had
to rely on a temporary plug to hold the entire contents of the plant
while the old lines to the lagoon were cut and permanently capped.
Tanker trucks where brought in to hold volume while these lines were
sealed off. As the Biscoe Plant continues to age and its components
require repair, valves and redundancy will be a necessity. Adding a
second clarifier will allow the Town to repair its existing one and

would give the plant emergency capacity should some component
fail. Additionally, a second clarifier will allow the town to visibly
inspect and repair sections of the clarifiers that would normally be
submerged. A more effective Clarifier could allow more settlement of
solids, enhancing turbidity. Additionally, the clarifier would reduce
solids entering the chlorine contact chamber which can lead to Fecal
Coliform violations.
The current bar screen is a passive system; simply put it is a metal
grate that requires daily attention and cleaning. This screen has larger
gaps than most of the newer automated bar screens. As such, small
debris still enters the plant. Fortunately for water quality purposes,
most of the debris settles or gets clogged in the motors of our
aerators requiring costly replacements. Ultimately, the more debris
removed before the secondary treatment process will prolong the life
of the plant and will produce cleaner effluent. Eliminating sediment
and -small pieces of plastic should enhance the overall turbidity of
effluent; which was .a major issue mentioned in the "NC DWQ Yadkin -
Pee Dee River Basin Plan: Lake* Tillery/Pee Dee River."
The Drying Beds saw a lot of use in the lagoon closeout project and
appear to have sustained many years worth of use in a short period of
time. This issue was raised by DWQ on our last inspection. The
inspector noted that a small investment now could save in the long
term; helping to prevent a potential spill. This component is relatively
minor compared to the rest of the project. In the previous grants
Biscoe mentioned in its narratives the desire to hold major plant
improvements pending on a potential regional solution. The
additional information section touches on the past grants and the new
perspective of the Town.
Water Quality Objectives and How They will be Achieved
As noted in the Project Description and Need section; this project
hopes to achieve:
• Enhanced Turbidity
• Reduced Fecal Coliform Violations
• Prevention of a Major Discharge/Spill Event
2

TOWN of BISCOE
I10 West Main Street P.O. Box 1228 Biscoe, N.C. 27209 Phone [phone] FAX (910) 42&3975
Turbidity will be effected by the bar screen at the primary treatment
and by the new clarifier in the secondary treatment. This
enhancement can be measured and quantified.
The reduction of Fecal Coliform violations can be achieved due to the
prevention of solids traveling to the chlorine contact chamber. This is
a part of our Daily Monitoring Report (DMR) and can be quantified. I
would be in error to believe that all fecal coliform violations would be
eliminated though just a clarifier. Improper sampling or even a high
flow event occurring in which our chlorine application doesn't adjust
immediately could both lead to violations.
The Prevention of a Major Discharge/Spill Event would be achieved by
both the repairs to the drying beds, the construction of the clarifier,
and the installation of valves to shift the flow. Fortunately, there is no
way to measure the impact that could be averted.
Additional Information
In the last two Clean Water Management Trust Fund grants. (2003A-
801; 2005A-502) the Town of Biscoe was working towards becoming
part of a regional wastewater treatment system. In 2000-2005 the
Town of Biscoe was heavily involved in talks to work towards a
regional waste treatment plant with the neighboring Towns of Star
and Troy. The potential startup costs of the system lead to the
concept being tabled. 'Since then, Troy has pursued regionalization to
the northwest assisting the Handy Sanitary District. The Town of
Biscoe, in conjunction with Montgomery County, is working to recruit
new businesses to the East of interstate 73174 to open the area to
potential development. Currently, the County and Town have entered
talks with a Biomass Electricity Plant for the eastern corridor; the
County would provide water and the Town would provide the
necessary sewer and municipal services. This industry would be one
of the largest investments locally in a decade. Regionalization is still a
future possibility and the Town is still excited for future discussions.
For the time being Biscoe needs to invest in its aging WWTP to be
able to attract new and maintain existing industry.
