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 , 3 gb (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 fast test will be performed after thirty days from
issuance of this permit during the months of � h°ti JvL o r—� . 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: Environmental Sciences Branca
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 clnemical/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 die 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.

Dear Mr. Ballard:
The Division of Environmental Management has reviewed your letter of May 29, 1991
requesting modifications to draft Permit No. NC0004685 for PPG Industries, Inc. The items are
addressed in the following:
(1) Monitoring only for fluoride and nickel will be required from the effective date of the
permit until July 31, 1992. The limits for fluoride and nickel will then become effective
August 1, 1992.
(2) The data for lead indicate five monthly values from April through August 1990 that
exceed the limit of 75.0 µg/1. In addition, the detection levels of < 0.1 mg/1(September
1990, February and March 1991) and < 0.2 mg/I (November 1990) used for lead are
higher than the limit and give no clear indication of whether the limit was met during
those months. Consequently, lead monitoring will remain weekly. Regarding nickel,
as this is the initial period for monitoring/limitation, weekly monitoring will provide
more data to establish discharge levels as noted by PPG in Item I of your request.
Chromium has been left at weekly monitoring to maintain consistency. After twelve
months of monitoring that shows constant compliance, we would be willing to
reconsider your request for reduced monitoring.

SUBJECT: Modification of Draft Permit for PPG Industries Inc.- Shelby
NPDES Permit No. NC0004685
Cleveland County
The Technical Support Branch has reviewed the May 29th letter from Mr. Lacy
Ballard of PPG Industries requesting modifications to the draft permit. Our rec-
ommendations concerning the modifications are as follows:
Item 1. The facility requests that the effluent limitations for fluoride and
nickel be reduced to monitoring only for the duration of the permit. Technical
Support concurs with the request for effluent monitoring for these newly per-
mitted parameters, however to continue monitoring until the permit expires in
December 1993 would be longer than we consider necessary. Mr. Ballard states
that "there is no data to establish the actual discharge levels for these two chemi-
cals ...", however an annual pollutant analysis run on PPG's effluent in December
1990 did indicate effluent concentrations for both. we recommend effluent monitoring
for fluoride and nickel for twelve (12) months only, after which the effluent limita-
tions of 5.4 mg/1 of fluoride and 263 ug/1 of nickel would become effective.
Item 2. The facility requests modifying the monitoring frequency for chromium,
lead, and nickel from weekly to monthly monitoring. A review of daily monitoring
reports for PPG industries indicates that chromium has been consistently reported
from <0.01 - <0.05 mg/1 since March 1990. It appears that PPG is in compliance with
the chromium limit of 149 ug/l. The data for lead indicate five monthly values from
April through August 1990 that exceed the limit of 75 ug/l. In addition, the detec-
tion levels of <0.1 mg/l (September 1990, February and March 1991) and <0.2 mg/1
(November 1990) used for lead are higher than the limit and gives no clear indication
of whether the limit was met during those months. Regarding nickel, since this is
the initial permit period for that limit/monitoring, it would appear that weekly
monitoring would give PPG more data based on the request in Item 1. Based on this
information, it is Technical Support's recommendation that PPG Industries continue
weekly monitoring of lead and nickel. To maintain consistency, we recommend that
chromium also he monitored on a weekly basis.
If there are additional questions, please feel free to contact me.

Dear Mr. Overcash:
Reference: NPDES Draft Permit NC0004685
PPG Industries, Shelby, Cleveland County
we have reviewed the draft NPDES permit for the Shelby facility
and find it to be acceptable with the following exceptions:
1. PPG Industries request that the permit discharge
limitations for fluoride and nickel be changed to monitoring
only for the duration of this permit in order to determine
discharge concentrations and, if necessary, determine the
course of action required to reduce concentrations to
acceptable levels.
At this point, there is no data to establish the actual
discharge levels for these two chemicals and PPG Industries
could be placed in immediate violation of the permit
conditions, without opportunity to address the problem,
should these limitations be included in this permit.
PPG Industries past compliance record and the absence of
chronic toxicity, as indicated by the bioassay test, should
support the request for a delay in establishing limitations
for these two parameters.
2. PPG Industries requests that the measurement frequency
for chrome, lead, and nickel be reduced to a more cost
effective level. Data from many years of monitoring for
chrome and lead do not indicate a need for the frequent
monitoring of these parameters. Given the continuous nature
of the manufacturing process, weekly monitoring is not
warranted and it is requested that these measurements be
reduced to monthly.
Thank you for your consideration in the permitting process. If
additional information is needed, please give me a call.
Sincerely
z�r
