CHRONIC TOXICITY TESTING REQUIREMENT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity in any two consecutive toxicity tests,
using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure - Revised *June 1988) or subsequent versions.
The effluent concentration at.which there may be no observable inhibition of reproduction or
significant mortality is $'? % (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 performed after thirty days from
issuance of this permit during the months of Pe.b iY14cc�� -- MyNov . Effluent
sampling for this testing shall be performed at the NNNPDE5 pefrfAtted 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
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 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.

Creek Basin Monitoring Plan

Mecklenburg County
A preliminary QUAL2E model was recently developed for the
Sugar Creek Basin which incorporated the Irwin Creek, Sugar Creek,
and McAlpine Creek WWTP's. The model indicated that the current
effluent limits as fined to the plants do not prot cat the._DO stan-
dard in the creeks. The current limits are as follows:
Flow (mgd) :
BOD5 (mg/1) :
NH3-N (mg/1) :
DO (mg/1) :
McAlpine Ck

The model predicts that the following sets of summer limits are
needed to protect the DO standard at design flow during 7Q10 con-
ditions:
BOD5 (mg/1) :
NH3-N (mg/1) :
DO (mg/1) :
McAlpine Ck

These limits should be qualified since the QUAL2E model was based
on hydraulic power functions estimated from only one set of flow
data and literature decay rates. Therefore, the model may have a
large amount of error in it. However, it is very likely that the
current limits will not protect water quality in the basin. The
previous models used to develop the current limits did not consider

the cumulative impact on dissolved oxygen as the discharges inter-
act in Sugar Creek, nor did they consider sediment oxygen demand
(SOD). In addition, updated long term BOD information indicates
that the CBOD:BOD5 ratios used in the original models were too low.
The instream monitoring data collected by the CMUD facilities
do not show many DO violations while the facilities were in com-
pliance. However, the facilities may be monitoring at locations
which are not near the DO sag points. I have therefore developed a
monitoring plan which may be included in each of the facilities
permits. The objectives of the monitoring plan are as follows:
1. To obtain a clear DO profile
2. To determine if nutrients are a problem
South Carolina has a water supply, Fishing Creek Reser-
voir, downstream of the CMUD facilities. If the CMUD point
sources are creating nutrient problems, nutrient limits may be
appropriate management strategies.
3. To determine if the CMUD facilities are the major contrib-
utor of any water quality problem.
4. To obtain background concentrations for modeling.
Please review the attached monitoring plan and make any com-
ments. It should be noted that the monitoring requirements listed
for the McAlpine Creek WWTP were recommended in its wasteload allo-
cation. However, the final permit has not yet been issued, and
changes may be able to be made in the permit.
The Instream Assessment Unit will continue its ongoing stu-
dies of the Sugar Creek Basin. The data collected by CMUD via the
monitoring plan described above will be added to the intensive
information being collected by the Division. All of the data will
aid the development of a basin management plan for Sugar Creek. If
you have any questions, please let me know.
