CHRONIC TOXICITY TESTING REQUIREMENT (QRTRLY)
The effluent discharge shall at no tune exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Coriodap nia 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 �%Q (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 Ee Mq¢ ,4uG Nov . 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 -I) for the month in which it was performed, using the
appropriate parameter code. Additionally, DEM Form AT -I (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 anv 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 a failure of permit condition.

Subject: Effluent Total Phosphorus and Total
Nitrogen Data,Belmont WWTP NPDES
Dear Mr.Gleason: Permit No.N00021181 Gaston County,N.C.
>n reply to your letter of January 28 1988 concerning
the above stated subject.
We have been monitoring said parameters since May V,1986 as per
amendment to our permit dated Feb.10,1986 , which required us to monitor
and report,but set no limits. We have also monitored the same parameters
in our Industrial Pretreatment Program since July 1, 1986.
About 75% of the wastewater treated at Belmont WWTP is Industrial
(Primarly dye waste) with extreamely high temperature and high PH with
slug discharges.
We have five Significant Industrial Users under Permit at this point
in time. The three smaller industries are now in compliance but the other
two( who contribute about 50% of our flow) are in the process of building
pretreatment basins to cool their effluent , reduce the PH and even out
the flow.
We have reviewed the data collected over the past 18 months and can
find no patterns , no relationships,only wide varyations, that lead to no
conclusions. We also feel sure that when the other 50% of our wastewater
passes through the Industrial Pretreatment processes being built,there is
going to be a change in readings and new analysis will need to be made,
before we can make any conclusions.
The present Industrial Pretreatment Discharge Permits expire November
14, 1989... Six months before that time ( March 1989) we should be doing a
new headworks analysis and hopefully by then the pretreatment facalities
mentioned above will have been on line for six months or so and we will
have collected some meaningful data to work with.

We share your concern and desire to protect Lake Wyle and want
to do what is needed. We also are concerned about the color pollution
problems in western North Carolina on the Pigeon River because we also
have color problems. And if EPA sets Statewide color limits we will
probably close down all of our Industries here too, and with no Industries
we will not have to worry about high concentrations of nutrients in
Lake Wyle.
Yours Truly,
James C.Johnson,Supt.Wastewater Treatment

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.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is 8 % (deed as treatment two in the North Carolina procedure
document). The permit holder shall perform ayarky monitoring using this procedure to establish
compliance with the permit condition. The first test will be�erformed after thirty days from
issuance of this permit during the months of AV X�- e��/ Effluent
sampling for this testing shall be performed at the NDES 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
appropriate parameter code. 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 strem. a
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 failure of permit condition.

Subject: Effluent Total Phosphorus
and Total Nitrogen Data
Belmont WWTP
NPDES Permit No. NC 0021181
Gaston County, NC
Dear Mr. Johnson:
Reference is made to the attached effluent data for Total
Nitrogen (N) and Total Phosphorus (P) for the time period 5/86
through 12/87.
This Office is concerned about the high concentration of
nutrients in your effluent because of the discharge directly to
Lake Wylie. The variability of the results suggests that
industrial users may be responsible. This Office recommends
that the City of Belmont address this problem via their
Pretreatment Program. A response to this letter regarding your
findings would also be appreciated.
If this Office can be of any assistance in this or other
matters, please feel free to contact me.
Sincerely,
c�

THRU: Trevor Clements��
SUBJECT: City of Belmont Effluent TP and TN Data
Attached for your information are self -monitoring effluent nutrient
data suggesting either improper analytical phosphorus and nitrogen proce-
dures or a great deal of variability in effluent characteristics. High
concentrations of nutrients are potentially of concern because of the
discharge directly to Lake Wylie.
Please advise if questions.
