None known within 1000'.

10. Receiving stream or affected surface waters:
UT Polecat Creek
a. Classification: WS-III
b. River Basin and Subbasin No: CPF 0306
c. Describe receiving stream features and pertinent
downstream uses: Stream has very little flow during
dry weather and has a history of appearing black and
having eutrophic conditions probably from solids
escaping the WWTP. Mats of material and bubbles are
often observed arising from the bottom of the stream
near the WWTP. Noxious conditions have been alleviated
by stream pumping by the ORC at the direction of the
Permittee.
Part II
DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
1. a. Volume of Wastewater to be permitted: 0.070 MGD
(Ultimate Design Capacity)
b. What is the current permitted capacity of the Waste
Water Treatment facility? Same.
c. Actual treatment capacity of the current facility
(current design capacity)? 0.070 MGD with sandfilters
activated.
d. Date(s) and construction activities allowed by previous
Authorizations to Construct issued in the previous two
years. A2C issued in March, 1994 for construction of
dual tertiary sand filters and a UV disinfection unit.
The Region understands that the above construction has
been postponed until a determination has been made as
to a possible connection to a POTW in Greensboro.
e. Please provide a description of existing or
substantially constructed wastewater treatment
facilities: Extended aeration treatment plant with
influent pump station and two parallel aeration systems
with diffused aeration, aerated sludge holding tank,
continuous flow recorder measuring device and standby
power and gas chlorinator. System may not always be
operated as a parallel system and old sandfilters are

Spray Irrigation: Not enough land withoututilizing
developable, property.
Connection to Regional Sewer System: Connection is being
pursued by Oakwood and may be possible within three years.
Subsurface: Not enough land without using developable
property.
Other disposal options:
5. Other Special Items: Associated creek conditions are not
good and complaints have been investigated by the WSRO due
to the water supply concerns. Recommend that the Water
Supply Section also be allowed to comment on this discharge
as well as the City of Randleman. An alternatives analysis
was submitted to the Division on October 12, 1993. This
alternatives study should be reevaluated prior to Dec. 31,
1996 due to- the enhanced potential for public sewer in the
Pleasant Garden community and reported recent discussions
between the City of Greensboro and Oakwood Land Development
Corp (owners of the Woodlake MHP WWTP). Conditions in the
creek may be somewhat due to low flows during summer months
and backed up waters; however, the Region still believes
that solids are likely to be escaping into the stream from
time to time.
PART IV - EVALUATION AND RECOMMENDATIONS
The WSRO recommends that the permit be reissued with a
stipulation that the sandfilters and ultraviolet
disinfection be installed withintwo years of permit
issuance or connect to the public sewer. The facility
should also be required to connect to the POTW.within 180
days of economically feasible availability regardless of any
upgrades. This recommendation is based on Part II Section
B.2. and Section 4.13. of the existing NPDES Permit.
