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 `February 1987) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is 96 % (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 Mai' melon, Sep, pee, . Effluent
sampling for this testing shall be performed at the IDES 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 dress:

Test data shall be complete and accurate and include all sur o: _'.g chemical/physical rn`asurements
performed in association with the toxicity tests, -as well asalldose/response data. Tota residual
chlorine of the effluent toxicity sample :n'ist be nmeasured and reported if chlorine is en oloyed 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 __mits.
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 constituteGnonconipliance with monitoring requirements.

• MEJIORANDUM
To: Ken Eagleson
Through: Jimmie Overton
From: Trish Finn MacPherson —F.--
Subject: Monroe WWTP
Benthic macroinvertebrate samples were taken above and below the
Monroe WWTP using the standard qualitative method on March 13, 1989. The
purpose of the survey was to document if additional treatment is required
to protect receiving waters. The Monroe WWTP has an existing discharge of
7 mgd (58% domestic and 42% industrial), with a proposed expansion to 9-
1 1 mgd. The plant discharges into Richardson Creek in the Yadkin River
basin in Union County.
The upstream benthos sample was taken at the plant's upstream
monitoring point at SR 1751 (Walkup Avenue). This site is below Lake Lee,
and also probably receives some urban runoff from the Town of Monroe. A
Fair bioclassification was given to this site based on SEPT/ST values of
12/62. The intolerant groups of Ephemeroptera, Plecoptera and Trichoptera
seemed to be especially stressed. Of the twelve EPT taxa collected, only
two were abundant, lsoperla bilineata (a winter stonefly) and Caenis (a very
tolerant mayfly). Eight of the ten remaining taxa were Rare, meaning only
one or two specimens were collected.
The downstream benthos sample was taken at the plant's downstream
monitoring point at SR 1006, about four miles below the discharge. The
plant had been finding low dissolved oxygen values (2.0 to 2.5) during the
warmer months at this site. A Fair bioclassification was also given to this
site based on SEPT/ST values of 14/52. The number of EPT fauna at this
site increased slightly, three taxa were Abundant, and only 6 taxa were
Rare. A distinct difference was noted in the amount of Aufwuch.s attached
algae or periphyton, present on the rocks between upstream and
downstream. The downstream site was a very slippery and slimey place.
Increased Aufwuchs is generally a sign of high organic loading. The high
abundance of the red midge, Chironomus, at the downstream site is another
indicator of high organic loading.

This sampling indicated that the Monroe WWTP is adding nutrients to an
already impacted stream, but that overall water quality is not changed due
to the discharge. Water quality is only Fair both above and below the
discharge. An ambient site on Richardson Creek, about eight miles below
the discharge (SR 1649) was sampled in July, 1987 and was also given a
Fair rating based on SEPT/ST values of 10/57. The benthic fauna at that
site was dominated by tolerant taxa reflecting the effects of enrichment
from the Monroe WWTP. Water chemistry data from that site from 1983 to
1986 also indicated elevated values for all nutrient categories.
