FROM: Mike Scoville OS
SUBJECT: Franklinville Waste Treatment Company WLA
NPDES No. NC0007820, WLA Request No. 5510, Randolph County
Franklinville Waste Treatment Company recently submitted an application
for an increase of the wasteflow limit in their NPDES permit. They are cur-
rently permitted for a 0.01 MGD discharge and have requested that this be
increased to 0.03 MGD. The WWTP was originally built for a textile mill,
and when the mill closed, the Franklinville Company took over the plant to
serve the Town's inhabitants. The 0.01 MGD flow was apparently arbitrarily
selected since no flow measurement device was available to measure waste -
flow. The request for a flow increase is largely to bring the facility into
compliance and not to take on any additional influent.
Through discussions between Technical Support, Permits & Engineering,
and the Winston-Salem Regional Office, it was concluded that a permitted
flow increase for the Franklinville facility does not require a wasteload
allocation since no additional flow is being discharged. Rather, it is an
administrative decision of whether the permitted flow increase should be
granted. The WLA request has been deleted from the records of Technical
Support and by this memo is formally returned to the Permits & Engineering
Branch.
If you have any questions or comments regarding this matter, please
contact me.

SUBJECT: Franklinville Waste Treatment Company
NPDES No. NC0007820, Randolph County
Franklinville Waste Treatment Company recently submitted an application
for an increase of the wasteflow limit in their NPDES permit. They are cur-
rently permitted for a 0.01 MGD discharge and have requested that this be
increased to 0.03 MGD, the physical design capacity of the plant. Permit-
ting the increased flow with the existing effluent limits represents a
threefold increase of pollutant loading to the Deep River, which already
experiences water problems in this area. It was the Town of Franklinville's
choice to take over and use the old Randolph Mills WWTP, but DEM cannot per-
mit them with secondary limits up to the design capacity simply because the
capacity exists.
It is the opinion of Technical Support that if the facility increases
it's wasteflow)the total loading of oxygen -consuming wastes should not be
increased; the attached approval form represents equivalent loading rates at
the two different wasteflows. Tertiary limits (BOD5=5, NH3-N=1) are not
being required like they would (and will) be for the larger facilities
(i.e., the Town of Randleman, the Town of Ramseur) when they expand. It is
important to note that the effluent limits for the larger Deep River dis-
chargers are not expected to change until they expand, unless an overall
basin plan is implemented which can provide for an orderly change for all
affected discharges.
If you have any questions or comments regarding this matter, please
contact me.

COMMENTS
Modification is an increase of flow from 0.01 MGD to 0.03 MGD.
Low DO concentrations and high BOD concentrations are well documented
in the Deep River above and below this discharge. The above limits
reflect BOD5 loading equivalent to those currently permitted. Similar
limit reductio s have occured along the Deep River. Other facilities
will also be a fected as their permits are renewed.
Recommend inst�ream monitoring of temperature, DO, fecal coliform, and
conductivity.
Recommend dechlorination be required in the permit.

MEjMORANDUM

FROM: Sherri V. Knight 9\L-
SUBJECT: Wasteload Allocation Ap oval Form
Franklinville Waste Tredtment Company
Randolph County .'
As we discussed in our recent telephone conservation,
the WSRO recommends that the subject facility be issued the
previous limits with the requested flow increase. There is
to be no increase in the flow discharged, just an increase
in the flow limit to allow the facility to become compliant.
The existing system consists of a pumping station, a
lined facultative lagoon, a clarifier unit that neither
returns sludge nor skims and a chlorination unit. The
system was originally used for Randolph Mills, an industry
which has been closed for many years. The design of the
system greatly exceeds the current flow rate.
2 8 1990
TECH: ,
lIt is highly unlikely that this facility would be able
to finance the amount of upgrading that would be necessary
if the recommended limits are included in the NPDES permit.
Mention was made of other dischargers whose limits may
also change when their respective permits are renewed. It
should be noted that the Town of Ramseur is in the process
of upgrading their wastewater treatment system. An aeration
system which can,but does not have to discharge to an
existing lagoon has recently been installed. This system
was not designed to meet a 10 mg/1 BOD5 limit nor a 2 mg/1
NH3N limit.
The Town of Randleman is also in the preliminary stages
of a wastewater treatment system upgrade. The engineering
propo1sa1 has been completed, however the Town has not yet
requested a flow increase. It is unlikely that the proposed
mod fications will be sufficient to meet the recommended
limits as this facility is located upstream of the
Franklinville Waste Treatment Company discharge.
While we realize that information is constantly being
added to system and that the problems in Deep River need to
be addressed, if is felt that the Division should be
reasonable in assessing all information when NPDES permits
are issued or reissued. For the dischargers involved(mainly
small towns), planning will be of utmost importance if
permit limits can be expected to change with each permit
renwal.
One other point that should be considered will be the
effect of the Randleman Dam should it become an eventuality.
Will Deep River below the Dam be maintained at 7Q10
conditions? If 7Q10 (if that) conditions are required, what
effelct will that have on the discharger's limits downstream?
And what effect will this combination of events have on the
quality and quantity of life that depends on the River?
If you have any questions, comments or information,
plea a call.
