Subject: NPDES Permit Correction
Permit No.NCO004260
CR Industries
Gaston County
Dear Mr.Schuh:
The Division issued NPDES permit number NC0004260 for the above referenced facility on
November 25, 1996. Since that time there were permit two modifications issued on July 6, 1998 and
December 14, 1998. Due to the recent plant closure, CR Industries is now discharging according to the
`A(2) Effluent Limitations and Monitoring Requirements' Page, from the December 14, 1998 permit
modification. A review of the permit has revealed that an error was inadvertently made in the December
modification. Specifically, the absence of a chronic toxicity condition on the A(2) Effluent Limitations
and Monitoring Requirements' page. This condition was mistakenly not included on the effluent
limitations page. This permit correction is intended to correct that oversight. Condition A(2) has been
modified to include chronic toxicity. Please note that in accordance with NCAC 213 .0508, the Division is
required to install toxicity testing for discharges of complex wastewater. The Division has deemed that
discharges originating from solvent contaminated groundwater as such.
The attached corrected permit pages should be inserted into your permit and the old one
discarded. If you have any questions or need additional information, please contact Michael Myers,
telephone number(919) 733-5083,extension'508.
Sincerely,
Kerr T. Stevens

Permit NC0004260
A(3) CHRONIC TOXICITY PERMIT LIMIT(QRTRLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia
dubia at an effluent concentration of 0.33%.
The permit holder shall perform at a minimum,quarterly monitoring using test procedures outlined in the"North Carolina
Ceriodaphnia Chronic Effluent Bioassay Procedure,"Revised February 1998,or subsequent versions or"North Carolina
Phase H Chronic Whole Effluent Toxicity Test Procedure" (Revised-February 1998)or subsequent versions.The tests will be
performed during the months of February,May,August,and November.Effluent sampling for this testing shall be performed
at the NPDES permitted final effluent discharge below all treatment processes.
- If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit limit, then-
multiple-concentration testing shall be performed at a minimum, in each of the two following months as described in"North
Carolina Phase II Chronic Whole affluent Toxicity Test Procedure" (Revised-February 1998)or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the highest concentration
having no detectable impairment of reproduction or survival and the lowest concentration that does have a detectable
impairment of reproduction or survival.The definition of"detectable impairment,"collection methods,exposure regimes,and
further statistical methods are specified in the"North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised-February 1998)or subsequent versions,
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form
(MR-1)for the months in which tests were performed,using the parameter code TGP3B for the pass/fail results and THP313
for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Branch
1621 Mail Service Center
Raleigh,North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later than 30 days after the
end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all concentration/response
data,and be certified by laboratory supervisor and ORC or approved designate signature.Total residual chlorine of the
effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the permittee
will complete the information located at the top of the aquatic toxicity(AT) test form indicating the facility name,permit
number, pipe number,county, and the morith/year of the report with the notation of"No Flow"in the comment area of the
form.The report shall be submitted to the Environmental Sciences Branch at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required,monitoring will be required
during the following month.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water Quality ;;
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,
minimum control organism reproduction,and appropriate environmental controls, shall constitute an invalid test and will
require immediate follow-up testing to be completed no later than the last day of the month following the month of the initial 14 ;;, ,:Y
monitoring.

This letter is to inform your Department that as of July 31, 1999 due to the
recent plant closure, the subject facility's industrial-domestic combined wastewater
treatment system (E1) has ceased operation and the equipment has been removed.
On August 2, 1999 the recently constructed groundwater remediation system (E2) was
started and is currently discharging 4-5 gpm continuously.
CR Industries is requesting a permit`modification if necessary as a result of our
business closure and current remediation activity.
If you have any questions please contact me at [phone] ext. 237.
