CHRONIC TOXICITY TESTING REQUIREMENT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnikchronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure - Revised *February 1987) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is 28 % (defined as treatment two in the North Carolina procedure
document). The permit holder shall perform quarterly mbnitoring using this procedure to establish
compliance with the permit condition.. The first test will be performed after thirty days from
issuance of this permit during the months of Tay 0 c t . Effluent
sampling for this testing shall be performed at the NPDES iDermitfed final effluent discharge below
all treatment processes. g
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: Technical Services Branch
North Carolina Division of
Environmental Management
P.O. Box 27687
Raleigh, N.C. 27611
•
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 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 modifted'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 coritrols, shall constitute an invalid test
and will require immediate mtesting(within.30 days of initial: monitoring event). Failure to submit
suitable test results will constitute a fail'urie of permit condition.

Dear Mr. Reynolds:
May 20, 1988
R. Paul Wilms
Director
Per our discussion on 4-24-88, I am sending you the specifics of the
sampling program that the City of Randleman has agreed to carry out
during the summer of 1988. As we discussed during my visit to your
facility, the sampling of the backwater below the discharge will require
the use of a boat. A site map and details of the sampling program are
attached.
If I can be of further assistance in this matter, please contact me
at [phone], ext. 507.

CHRONIC TOXICITY TESTING REQUIREMENT (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 *February 1987) or subsequent versions.
Thc effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is 28 % (defined as treatment two in the North Carolina procedure
document). Thc permit holder shall perform Quarterly monitoring using this procedure to establish
compliance with the permit condition. The first test will be performed after thirty days from
issuance of this permit during the months of 4 r T.A 1 ) ocf , 3-cc el. 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: Technical Services Branch
North Carolina Division of
Environmental Management
P.O. Box 27687
Raleigh, N.C. 27611
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 test data from this monitoring requirement or tests performed by the North Carolina
Division of Environmental Management indicate potential impacts to the receiving steam, this
permit may be re -opened and modifietoinclude 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 a fat7'ureof permit condition.

SUBJECT: Permit Renewal for the City of Randleman (NC0025445) bow:dl Ua
Technical Services recently received a wasteload allocation request
in conjunction with an application for permit renewal by the City of
Randleman. Upon review of our modeling notes and file memorandums for
this facility, it is apparent that the City of Randleman was issued
incorrect limits for their permit in 1980. All subsequent efforts to
correct this oversight were unsuccessful, and thus now we are faced with
renewing a permit for a facility that presently has secondary limits and
yet discharges to a sensitive system - slow -moving backwater above a dam.
I have attached copies of Randleman's existing permit and a chronology of
the attempts to correct the permitted limits.
Review of instream data shows that there have been violations of the
State's water quality standard of 5 mg/1 dissolved oxygen (DO) both above
and below Randleman's discharge. At their downstream self -monitoring site
(the Worthville Bridge), Randleman's lowest recorded DO reading is 3.1
mg/1 (at 34% saturation). DEM's lowest recorded DO reading at this site
is 2.8 mg/1 (also at 34% saturation). Of particular concern is the fact
that most of the self -monitoring DO readings taken at the downstream site
in 1985 are showing saturation to be around 50-60 percent while most of the
DO saturation readings taken at this site in 1986 are in the 95-105% range
(they did not monitor in 1987). This inconsistency could be the result of
many factors including poor sampling protocol, changes in personnel that
perform the sampling, or a developing algae problem in the backwater above
the dam where the downstream site is located.
In addition, it appears that the concentration of carbonaceous BOD (CBOD)
coming from upstream of Randleman is greater than what we normally use for
upstream boundary conditions - our standard assumption is 2 mg/1 CBOD and
the available data indicate that the upstream CBOD concentrations may be as
great as 5.4 mg/1. These higher concentrations of CBOD, quite possibly the
residual CBOD from upstream industrial discharges (we often find that
industrial BOD breaks down very slowly, and thus is in the system for a
considerable length of time), reduce the available assimilative capacity
for a wastewater discharge into the river.
If Technical Services were to proceed with this wasteload allocation
as if it were a new application instead of a renewal, we would recommend
limits of 6 mg/1 BOD5 and 2 mg/1 NH3-N. This is in sharp contrast to the

Steve Tedder
Randleman Permit Renewal
- page 2 -
the existing secondary limits or the previously recommended limits of 16
mg/1 BOD5 and 9 mg/1 NH3-N. This presents us with a dilemma since Randle-
man is well aware of the fact that it was DEM's error that gave them the
secondary limits and that now we want to make these limits more stringent
(although from the previous letters that we have written them, they believe
tighter limits mean 16 mg/1 BOD5 and 9 mg/1 NH3-N).
Since this facility is currently able to achieve nitrification, my
suggestion is that we revise the 16 mg/1 BOD5 and 9 mg/1 NH3-N limits to
28 mg/1 BOD5 and 2 mg/1 NH3-N (same ultimate BOD). Review of Randleman's
effluent monitoring data (attached) shows that this would enable them to
basically stay in compliance. I further recommend that we assign these
limits for only a short-term permit or with a reopener clause and that we
do a field survey in the near future.
It is important that we design the survey to provide the data that
will address the special problems encountered when analyzing a slow -moving
system. This includes estimating velocity for the backwater above the dam;
a flow balance that includes above the backwater, at the dam, and below the
dam; determining the upstream concentrations of CBOD, NBOD, and DO; isolating
1 the components of the DO deficit (CBOD, the different nitrogen fractions,
SOD); diurnal, depth -integrated sampling in the area above the dam. All of
these factors need to be considered if we are to predict what level of
treatment will be required of the Randleman facility in order to protect
i the water quality of the Deep River in the area immediately downstream of
their discharge.
In addition, I suggest that we ask the City of Randleman to assist us
in evaluating the effect of their discharge on the water quality of the
Deep River in this sensitive area. Specifically, I propose that we have
additional monitoring requirements in their new permit for the period of
time that the system will most likely be experiencing critical conditions -
i.e., low flows and high water temperatures. These types of.conditions
usually occur during the months of July through September. Therefore, we
should increase the frequency that they perform instream monitoring as well
as adding some additional sampling sites below their discharge during this
period of stream stress.
Please contact me if you desire further clarification on this matter.

Subject: Re -opening NPDES permit for Randleman
The Randleman NPDES permit was reissued in April 1986 without a
wasteload allocation. The limits contained in the permit are incorrect
and the permit does not contain the toxicity limit that was recently
developed for the facility. Technical Services was working on the WLA
at the time the permit was reissued. The errors involved with this
permit are summarized in my June 2, 1986 memo to George Everett (copy
attached).
The Deep River is a sensitive area both ecologically and politi-
cally. I would like to recommend that the permit be re -opened and the
correct limits inserted as soon as possible. The permit does not expire
until 1988.
Please let me know if you have any questions.

From: Meg Kerr //L
Through: Steve Tedder
Subject: NPDES Permit for Town of Randleman
Sherry Vadin with the Winston-Salem Regional Office called
last week to discuss the limits in the Randleman NPDES permit.
She had found discrepancies in effluent limits between old
Randleman permits and permits recently issued to the town. I
reviewed our wasteload files and the Randleman permit file in
an attempt to resolve her questions. These files reveal sev-
eral major oversights in this permit that I would like to -
bring to the staff's attention. My findings are summarized in
chronological order below.
June 30, 1980 Randleman's permit was issued, expiration
date was May 31, 1985. The permit contained limits for a 0.5
mgd plant and for a 1.0 mgd plant. The wasteload allocation
attached to the permit is for Asheboro, not Randleman and the
limits in the permit for 1.0 mgd are wrong (30/30 instead of
15 BOD-5, 10 NH3, 5 DO).
August 13, 1981 DEM sent the town a letter notifying them
of the error in the permit. A new limits page was sent with
correct limits. A wasteload allocation was also included. ui
April 5, 1983 At the town's request, DEM sent the town
modifications to the permit with a revised compliance sched-
ule. The letter included 3 permit limits pages - 2 are correct
and the third is the incorrect set of limits.
August 1, 1983 In response to a request for an altered
compliance schedule, DEM sent the town another permit modifi-
cation. This modified permit contained incorrect limits (30/30
at both flows) and also extended the expiration date to July
31, 1988. No wasteload allocation was attached.
May 28, 1985 A modified permit was sent to the Town with
the new modified monitoring requirements (no upstream or down-
stream monitoring). Again the limits were listed incorrectly.

ARril3, 1986 The Town requested DEM to increase the
design flow in the permit from 1.0 mgd to 1.25 mgd. Permits
staff studied the hydraulic capacity of the plant and evalu-
ated its ability to meet its limits (which ones?). The permit
was reissued, again with incorrect limits and no wasteload
allocation.
I have talked to Dale and Arthur about this permit and
they agree that this one was handled incorrectly but just
managed to slip through the system. I am writing this memo to
clarify the facts in case questions arise, not to blame staff
for unintentional oversights.
I will be reviewing the Deep River model used to develop
the Randleman limits sometime in the next few weeks. Once the
limits are verified, we might consider notifying the Town and
working to reopen the permit.
