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 34.0 %.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North
Carolina Ceriodapbnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North
Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The
tests will be performed during the months of January, April, July, and October. 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 Effluent 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 THP3B for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Water Quality
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 month/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 indude 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 monitoring.

Permit NC0035173
A. (4.) BIOCIDE CONDITION
There shall be no chromium, zinc or copper added to the treatment system except as pre -approved
additives to biocidal compounds.
The Permittee shall obtain authorization from the Division prior to the use of any chemical additive in the
discharge. The permittee shall notify the Director in writing at least ninety (90) days prior to instituting the
use of any additional additive in the discharge, which may be toxic to aquatic life (other than additives
previously approved by the division). Such notification shall include the completion of a Biocide Worksheet
Form 101 (if applicable), a copy of the MSDS for the additive, and a map indicating the discharge point and
receiving stream.

RESIDUALS MANAGEMENT PLAN
Kobe Copper Products, Inc.
Wastewater Treatment Facility
Pine Hall, North Carolina
NPDES Permit No. NC0035173
Description of Residuals
The residuals from this facility consist of waste activated sludge from an
extended aeration wastewater treatment plant treating 100% domestic sewage
from Kobe Copper's Pine Hall North Carolina manufacturing facility.
Waste activated sludge is periodically removed from the treatment plant in
accordance with a schedule determined by the Operator in Responsible Charge
(ORC) in order to maintain the proper solids inventory, sludge age, etc. for
efficient plant operation.
Waste Sludge Stabilization
Waste activated sludge is transferred from the treatment plant into a separate,
on -site aerobic digester. The sludge is continuously aerated in the digester in
order to provide stabilization by the aerobic digestion process.
Residuals Disposal
Periodically, as determined by the ORC, stabilized waste sludge is pumped from
the digester to a sludge hauling truck for off -site disposal. The procedures
below are followed:
1. Air to the digester is temporarily turned off
2. Sludge is allowed to settle in the digester until a relatively clear
supernatant develops
3. A portion of the supernatant is returned (pumped) back to the
influent of the treatment plant, as required
4. The thickened waste sludge is transferred to the tank truck for
disposal
At the present time, the stabilized and thickened waste sludge is transported by
Richard Jenkins Septic Tank Co. under their permit No. 525. The sludge us
ultimately disposed of at North Buffalo WWTP which operates under NPDES
Permit No. NC0024325.
Recordkeeping

Sludge disposa records are maintained ,by Nortr) fit.ifffIo WWTP & Richard
Jenkins Septic Tank Co. and are located at North Buffilo WWTP, White Street,
Greensboro, NC and at Richard Jenkins Septic tank Co., 3801 Autumn Forest
Drive., Brown Summit, NC. Records pre pyailat for inspection by regulatory
authorities by appointment with the sORC and(Qr Kobe Copper Products, Inc.,

SUBJECT:
Dear Mr. McClain:
NOTICE OF VIOLATION
Whole Effluent Toxicity (WET) Testing
Copper and Zinc Action Level Policy
NPDES Permit No. NC0035173
Kobe Copper WWTP
Stokes County
This is to inform you that a review of your toxicity self -monitoring report form for the month of
January 2001 indicates a violation of the toxicity limitation specified in your NPDES Permit. You should
undertake necessary actions to eliminate or reduce effluent toxicity to acceptable levels.
In addition, this correspondence contains important information on the Division's Copper and
Zinc Action Level Policy which is triggered by failure of two or more toxicity limit violations during
the toxicity testing calendar quarter specified by the toxicity testing special condition of your NPDES
Permit. Attachments addressing policy implementation and a copy of the Division's Toxicity Reduction
Guidance have been included with this Notice of Violation.
You should initiate follow-up toxicity testing upon a single WET test failure which occurs
during the toxicity testing calendar quarter.
Your facility is currently monitoring for copper and/or zinc and is exceeding the action level for
these parameters. The policy states that whenever a facility experiences two or more toxicity limit
violations during a toxicity testing calendar quarter, the NPDES Permit will be modified to include
numeric limits for copper and/or zinc UNLESS the permittee provides one or more of the following:
1. Instream measurements of dissolved metal during low flow conditions that demonstrate
compliance with the Action Level standard
2. A revision of the.prospective permit limit using improved inputs that in concert with
existing or additional monitoring data demonstrates compliance with the Action Level
standard
3. Toxicity Identification Evaluation (TIE) results that definitively rule out copper and/or zinc
as causes of effluent toxicity
4. Demonstration by an alternative method approved by the Division and EPA that copper
and/or zinc is not the cause of toxicity

2
The Division has evaluated your copper and/or zinc monitoring data. The Division has also
developed a prospective NPDES permit limit based on your facility's instream waste concentration, the
copper and/or zinc action level criterion and a translator procedure. Based on this data your prospective
copper permit limit is 44 µg/L.
The permittee, upon experiencing two or more toxicity limit violations during a toxicity
testing calendar quarter must either provide DWQ with:
a) Written notification indicating acceptance of the prospective copper
and/or zinc permit limit. Notification is due within 30 days after the date of
the second WET Notice of Violation.
OR
b) Written notification indicating your choice of option(s) as noted on page
one of this correspondence. Notification is due within 30 days after the date
of the second WET Notice of Violation.
Written notification (a or b above) shall be sent to:
North Carolina Division of Water Quality
Environmental Sciences Branch
Aquatic Toxicology Unit
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Please note that if you choose item b) above, you will be given nine months to submit
documentation that eliminates copper and/or zinc as causative effluent toxicants. Your final report
should be comprehensive and include all data used to support your conclusion(s). Should the data
indicate copper and/or zinc as the source of effluent toxicity or if the data are inconclusive as to copper
and/or zinc's role as a toxicity source, then the NPDES Permit will be reopened and the metal limits
specified above will be applied to the permit. The report is due nine months after the date of the second
WET Notice of Violation.
Three copies of the final report shall be submitted to:
North Carolina Division of Water Quality
Environmental Sciences Branch
Aquatic Toxicology Unit
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
You should consider submitting the above correspondence certified mail.
Failure to notify DWQ of your acceptance of a copper and/or zinc limit, failure to notify
DWQ of your option selection or failure to make acceptable demonstration to DWQ that copper
and/or zinc are not causative effluent toxicants within the stated time frames will result in
reopening of the NPDES Permit to include copper and/or zinc numeric limitations, as appropriate.
Please note that your actions to notify DWQ of prospective limit acceptance or to notify DWQ
of plan option(s) and subsequent submission of a plan are contingent upon two or more toxicity NPDES
permit limit violations occurring during a toxicity testing calendar quarter.

3
Also note that the WET limit will remain in your NPDES permit regardless of whether metals
are the source of effluent toxicity. The data resulting from your actions to disprove copper and/or zinc as
sources of effluent toxicity will determine whether NPDES Permit limits will be assigned for these
parameters. You are responsible for initiating actions to address these issues.
You may consider entering into a Special Order by Consent (SOC) with DWQ. A SOC provides
regulatory relief for specific NPDES permit limit violations and, if signed, will contain a requirement to
conduct a Toxicity Reduction Evaluation. The SOC will contain a compliance schedule, stipulated
penalties for failing to meet milestone activity dates and may contain upfront penalties to settle past
permit limit violations.
Additional information regarding the Division's copper and/or zinc action level policy can be
found at the following web site - http://www.esb.enr.state.nc.us. Click on the "Aquatic
Toxicology" Unit and go to the prompt "AT Downloadable Files" located at the bottom of the page.
This web site also contains EPA's "Toxicity Reduction Evaluation Guidance for Municipal Wastewater
Treatment Plants." Section 4 of this document contains pertinent information on Toxicity Identification
Evaluations.

Dear Mr. Sprinkle:
The Division received your request for approval to use STABREX ST70 on February 12, 1998. Your
request was reviewed by personnel from the Division's Aquatic Toxicology Unit (ATU). Due to
uncertainty over the potential toxic impact to the receiving stream, the Division is granting your
request on a trial basis only. This permit modification allows use of STABREX ST70 in liquid form for
thirty days following receipt of this letter. Monitoring data are to be collected and submitted to the
Division per the attached memo from Melissa Rosebrock of the ATU.
All other terms and conditions contained in the original permit remain unchanged and in full
effect. This permit modification is issued under the requirements of North Carolina General Statutes
143-215.1 and the Memorandum of Agreement between North Carolina and the U. S. Environmental
Protection Agency.
If any parts, measurement frequencies or sampling requirements contained in this permit
modification are unacceptable to you, you have the right to an adjudicatory hearing upon written
request within thirty (30) days following receipt of this letter. This request must be a written petition
conforming to Chapter 150B of the North Carolina General Statutes, filed with the Office of
Administrative Hearings, Post Office Drawer 27447, Raleigh, North Carolina 27611-7447. Unless such
demand is made, this decision shall be final and binding.
If you have any questions concerning these permit modifications, please contact Charles Weaver
at [phone], extension 511.

From: Melissa Rosebrock
Subject: Kobe Copper Products, Inc.
Biocide/Chemical Treatment Use
NPDES No. NC0035173 (003)
Stokes County
Kobe Copper has submitted STABREX ST70 for approval. Data submitted by the facility and
chemical supplier concerning dosage rate, degradation, system volume, average daily discharge, toxicity
of the active ingredient(s) and/or breakdown products, and minimum stream flow have been reviewed
and evaluated.
The facility wishes to change the chemical formulation, and consequently the "trade name," by
dosing the proposed biocide as a liquid rather than a solid (tablet). The facility does not propose
changing active ingredients, however. Since the facility was not able to provide acceptable half-life data
for STABREX ST70, we evaluated the proposed product based on no degradation (NA -not available).
Calculations performed using "NA" resulted in the instream biocide concentration exceeding the
regulated limitation.
The facility still proposes to use STABREX ST70 on a trial basis, however. They believe the liquid
form of the biocide will be non -toxic based on previous total chlorine monitoring data obtained while
using the tablet formulation (see attached). The facility proposes to continue monitoring, measuring, and
recording the total chlorine on a daily basis over a one month period to document that the free halogen
concentration in the cooling tower discharge is below the regulated limitation of 0.016 mg/1 (see
attached spreadsheet).
Of the methods presented to us by Kobe Copper, the most appropriate instrument/test for measuring
total residual chlorine would be the Pocket Colorimeter (catalog #46700-00). Although this colorimeter
only has an estimated detection limit of 0.03 mg/L (see attached), it is our professional judgement that a
total chlorine value below the colorimeter's detection level would pose no threat to aquatic organisms in
the receiving stream. Per Kobe Copper's letter of May 1, 1998, monitoring results are to be submitted to
our office after completion of the trial period. At that time the facility may request approval for use on a
permanent basis.

POINT SOURCE BRANCH
We have received and reviewed Kobe Copper's request to change biocidal
products. Per your facility's NPDES permit, issued 2/1/97, outfall 001 is operated with a
chronic toxicity monitoring requirement and limit. The whole effluent toxicity test should
provide validation that chronic toxicity of the effluent is acceptable. Therefore, approval
from this office is not necessary for outfall 001.
A completed Biocide/Chemical Treatment Worksheet-Form 101 must be submitted
and approved prior to biocidal discharge of Stabrex ST70 through outfall 003. We have
enclosed a copy of the appropriate form for your convenience. The completed worksheet
and supporting data should be submitted to: Mr. Dave Goodrich, NPDES Unit
Supervisor, NC DENR-NPDES Unit, P.O. Box 29535, Raleigh, NC, 27626-0535.
If I can provide you with further information or you have questions, please call me

Subject: Waste Water Treatment Permit # NC00351 73
Dear Ms. Rosebrock:
The purpose of this letter is to update our Waste Water Treatment permit for outfalls 00l
and 003. This letter Is :i follow-up to the discussion between yourself and Michael
Mitchell. from Nalco Chemical Company on September 30. We also request that you
provide a written procedure to update this permit.
The modification to our water treatment that we are considering, may affect the existing
Waste Water Treatment permit. This modification is in regards to our biocide. We
would like to change from the hydantoin chemistry to a stabilized bromine chemistry
(MSUS attached). Wth this new chemistry. our free chlorine residual will be reduced to
0. t ppm and total chlorine residual to 0.5 ppm.
As was discussed with Michael Mitchell previously. this change may not affect our Waste
Water Treatment permit as a result of our quarterly monitoring requirements. Regardless.
we request your formal recommendations on how to proceed.
