This WLA was prepared from a speculative WLA for the Town of Mayodan WWTP proposed expansion
from 1.25 MGD to 3.00 MGD. A level B constructed for the Town of Stoneville WWTP was used for this
analysis. The model was constructed to predict the results of an SOC (flow and TSS) for the Town of
Stoneville WWTP. It includes the towns of Stoneville and Mayodan on the Mayo River and Madison on
the Dan River. Updated for the increase in flow from Mayodan and new flow rates for the Mayodan
area, the model predicts no interaction between the Stoneville and Mayodan plants. The minimum DO
concentration predicted from the increase in flow from the Mayodan plant is 7.68 mg/1 at the discharge
point (45 mg/1 CBOD) or 7.50 mg/1 at mouth of the Mayo River (60 mg/1 CBOD). It should be noted
that the model predicts a second DO sag downstream of the Madison plant and the Mayo river. This
minimum is 7.33 mg/1 at mile 5.6 after the Mayo river at 45 mg/1 CBOD and 7.30 mg/1 at mile 6.00 after
the Mayo river at 60 mg/1 CBOD.

CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic Bioassay
Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or significant mortality
is (4, % (defined as treatment two in the North Carolina procedure document). The permit holder shall perform
quarterly monitoring using this procedure to establish compliance with the permit condition. The first test will be
.. . rformed after thirty days from the effective date of this permit during the months of
)45L-v- ,� wh., ()ci- . Effluent sampling for this testing shall be performed at the NPDES
permitted final effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B.
Additionally, DEM Form AT-1 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in
association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent toxicity
sample must be measured and reported if chlorine is employed for disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly monitoring will
begin immediately until such time that a single test is passed. Upon passing, this monthly test requirement will
revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of
Environmental Management indicate potential impacts to the receiving stream, this permit may be re -opened and
modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism
survival and appropriate environmental controls, shall constitute an invalid test and will require immediate
retesting(within 30 days of initial monitoring event). Failure to submit suitable test results will constitute
noncompliance with monitoring requirements.

Rockingham County
Dear Mr. Carlton:
The NPDES Permits Group has reviewed your letter of July 16, 1990, requesting to
reactivate the old wastewater treatment plant. Reactivation of the old plant will require a
major modification of the permit issued to Mayodan.
The following information will be required to be submitted for a review of the
expansion request:
1. A permit processing fee of $300.00 with the check made out to the NC Department
of EHNR.
2. A Standard Form A application completed and submitted in triplicate.
3. A USGS map that shows the discharge location of the new plant and the old plant.
Your letter indicates that Mayodan is considering an expansion of its capacity from
1.25 MGD to 3.0 MGD. You should request a modification of the NPDES Permit as soon as the
town is sure that it will expand its plant. This can help avoid any unexpected delays in
construction of the plant.
If you have any questions, please contact me at [phone].

Mayodan WWTP Color Limits
,(kkt /
cl<def `ilk
A simple mass balance to protect for a stream standard of 24 ADMI was used to calculate
limits for color in the effluent of the Mayodan plant after the expansion to 3.00 MGD. A
draft report, An Update of Color Control Activities in the Smith and Dan River Basins,
NCDEHNR-DEM, January, 1990, indicated a weekly flow pattern in the Smith River
regulated by the Philpott Dam near Martinsville, Virginia. The pattern affected flows in the
river at the City of Eden --Mebane Bridge WWTP. The color limits were calculated using
the S7Q10 for the river at the plant site, however, USGS gaged stations and daily flow
studies indicated the regulated flow from the dam reduced the flow below the S7Q10 for
the Smith River. Mass balances were calculated using a low flow value calculated from the
daily flow data.
In light of this, flow data was examined from the USGS station #02071000 at SR 2150 on
the Dan River, about half way between the confluence of the Mayo River and the City of
Eden --Mebane Bridge WWTP. This data, for 1989-Sep 1991, is illustrated in Figures 1
and 2. The data does not appear to show any pattern in flow throughout the year. Figure 2
shows flows for the river do not reach S7Q10 levels any of these three years. The
assumption is then made that there is not a pattern of flow and S7Q10 values for the Dan
River from the Mayodan WWTP should give a very conservative estimate of allowable
color limits.
A simple mass balance:
Cw = [ (Qd * Cd) - (Qu * Cu) ] / Qw
where: Cw = Allowable Effluent Pollutant Concentration
Qw = Wasteflow in cfs
Cd = Allowable Downstream Pollutant Concentration
(i.e. stream standard--24 ADMI)
Qd = Downstream flow
Cu = Upstream Pollutant Concentration (i.e. background)
Qu = Upstream flow (S7Q10) (Jc. c e 52a)13_ rep Eden' me eve &)
was calculated for the Mayodan WWTP using:
Qw = 4.65 cfs (3.00 MGD * 1.55)
Cd=24ADMI
Qd = (4.65 + 313) cfs
Cu=24ADMI
Qu = 313 cfs
3"r,+erac,on LEI er'1 ra ,(-
C,:.rxiictered , ( mJ►e0-2aAk
Using zero for background conditions, the mass balance gives an allowable concentration
of alliMielei ADMI; using 24 ADMI for background, rl 10 (111.8) ADMI.
