DIVISION OF ENVIRONMENTAL MANAGEMENT
Recommendations for Color Monitoring for City of Shelby -Broad River WWTP
EI
15 NCAC .0211(b)3(F) states for colored wastes - only such amounts as will not
render the waters injurious to public health, secondary recreation, or to
aquatic life and wildlife or adversely affect the palatability of fish, aes-
thetic quality or impair the waters for any designated uses.
Within 120 days of the effective date of this permit, the permit holder shall
begin monitoring for color at the Effluent, Upstream, and Downstream designated
sites (50 ft upstream and 50 ft downstream), and one sample of effluent
diluted with upstream water at a concentration replicating 7Q10 conditions. All
samples shall be grab samples.
Analysis shall be performed in the field using the "glass disks field method"
(Standard Methods - 204A).
Analyze samples as follows:
(a) using the platinum -cobalt method; and
(b) Using a narrow -band scanning spectrophotometer to produce a COMPLETE spec-
tral curve of the visible spectrum (350-750 nm). Calculate and report results
in ADMI color units from the information indicated.
Samples should be taken free from turbidity (True Color) and at natural pH.
During summer months (April -October) collect samples on Mondays, Wednesdays, and
Fridays and during the winter months (November -March) collect samples on Wednes-
days.
The permit holder shall submit annual reports summarizing the available color
monitoringinformation. Include factors which may have had an impact on the
levels of color in the effluent and receiving stream, including, but not limited
to, rainfall, streamflow, production plant operations, and treatment plant oper-
ations. Submit the report to the Water Quality Section Chief no later than Feb-
ruary 15th of each year.

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 *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is /z % (defined as treatment two in the North Carolina procedure
document). The permit holder shall perform guarter(v monitoring using this procedure to establish
compliance . ;:th the permit condition. The. first test will be performed after thirty days from
issuance of this -permit during the months of NAYAkk Abt/ f7 Effluent
sampling for f his testing shall be performed at the NPDES permitted final effluent discharge below
all treatment s • es.
All toxicity tingresults required as part of this permit condition will be entered on the Effluent
Discharge- nitoring 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 o' 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.
