A (2). 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 13%.
The permit holder shall perform at a minimum, _guarterl monitoring using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or
"North Carolina Phase 11 Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent
versions. The tests will be performed during the months of March. June, September, and December. 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 Procc°dure" (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 it 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, DW9 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 pertnittee 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 Iimits.
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.

Called Connie Kagey at EPA today. She was going to check and verify whether she had
received the request. Also noted that she had to wait until she received "several
requests" before she could respond because she had to send up her report to
headquarters. She also indicated that the facility would probably not be downgraded
unless it was in significant non compliance. I told her that there were no problems
with compliance, that we just thought that it was not a major industrial facility.
She said it would probably be 2-3 months before I would get a response.
I will go ahead and issue the permit when all other info is received and will address
the major/minor issue when EPA's response is received. It will probably be the end
of the year or later.

SUMMARY OF FACILITY INFORMATION AND WASTELOAD ALLOCATION
SGL Carbon is requesting renewal of its existing NPDES permit. Permittee also has a
stormwater permit (NCS000009) and notes that facility stormwater drains also
discharge to outfall 001. This may account for TSS, O&G and copper residuals in the
effluent.
The facility is a manufacturer of synthetic graphite products. Raw materials
consumed include coke, coal tar. pitch, and petroleum pitch. The main products are
mainly electrodes for use in the steel industry. They produce 3.3 million pounds of
graphite product per month.
The types of wastewater are 0.6 mgd of noncontact cooling water and 0.3 mgd of
contact cooling water. Cooling towers are used. Application notes that most of the
discharge is from non -contact cooling water. There is some contact cooling water
discharge from baking furnaces that utilize water seals to prevent combustion gas
emissions, there are not significant chemical additions to the discharge from this
process.
MAJOR/MINOR FACILITY RATING
SGL Carbon LLC has been previously rated as a major industrial facility. The facility
has no treatment processes and discharges primarily non -contact and contact cooling
water. Company manufactures synthetic graphite products.
SGL Carbon LLC's renewal application lists SIC Code 3624. The 1987 SIC Code has
the title of Carbon and Graphite Products. There is no CFR Part or Subpart listed in
Appendix A SIC Code Cross Reference Guide and Total and Human Health Toxicity
Number. I had contacted Samantha Lewis of EPA, and asked whether an industry
with an SIC Code of 3624 would be included in the Electrical and Electronic
SCI, Carbon Lf C Fact Sheet
1Vk'l: FS PeriniL [ssulance
Page 1

Components Category. Her email response was that Carbon and Graphite Products
subcategory was excluded from the Electrical and Electronic Components category
because "pollutants would be in trace amounts and in quantities too small to be
effectively reduced by treatment."
After review of the application, decided to reevaluate the rating to see if it's properly
categorized as a major industrial discharger. Used the NPDES permit rating sheet
and based on the calculated total score of 75, it was my recommendation that SGL
Carbon should not be categorized as a major facility.
Factor 1 Toxic Pollutant Potential Total Points: 40
Basis: Appendix A Carbon and Graphite Products have a Total Toxicity Number of 8
and Toxicity Group 8 rates total points: 40.
Factor 2 Flow/Stream Flow Volume Total points: 10
Basis: Used Section A, based on the quantity and type of wastewater flow discharged
from the facility. SGL discharges both noncontact cooling water and process
wastewater (contact cooling water). The process wastewater is greater than 10% of
the total discharge. The application indicates that contact cooling water is about 33%
of the total discharge. Based on this information, it was determined that SGL Carbon
would be Type II wastewater flow, and the flow was < 1 MGD. The application
indicates average flow of 0.9 MGD. Total points: 10
Factor 3: Conventional Pollutants Total Points: 5
Basis: there are no oxygen demanding or nitrogen pollutants limited in the discharge.
There is a monthly average limit for Total Suspended Solids and the limit when
converted to lbs/day is between 100 to 1000 lbs/day. The TSS limit is 30 rng/l. The
Highest monthly average flow is 0.79 MGD. This converts to 197.66 lbs/day. Total
points: 5
Factor 4: Public Health Impact Total Points: 20
Basis: The receiving stream, Silver Creek, is classified as WS-N (water supply). It is
located in a protected area for the watershed. The human health toxicity group for
Carbon and Graphite products is group 8, which rates 20 points.
Factor 5: Water Quality Factors Total Points: 0
Basis: None of the effluent discharge limits are based on water quality factors of the
receiving stream and there is no wasteload allocation assigned to the discharge. The
receiving stream is in compliance with water quality standards. Silver Creek is not
listed on the 303d list for impaired streams. The facility does not exhibit the
reasonable potential to violate water quality standards due to whole effluent toxicity.
SGL Carbon has passed all toxicity tests since March 2001.
Factor 6 Proximity to near Coastal Waters Total Points: 0
Basis: The facility is located in Burke County, NC in the western part of the State and
is not near coastal waters.
Total points from Factors 1-6: 75 points
Since the total points are not greater than or equal to 80, the facility is not a major.
This is a modification from the faeffity's previous rating as a major industry.

_RECEIVING STREAM:
Silver Creek, is a class WS-1V water in subbasin 030831. It is not listed on North
Carolina's 2002 303(d) list and has a use support rating of "supporting" based on
monitored data.
Existing Effluent Limits (issued 1/26/2001)
Qw = not limited
TSS = 30 mg/l
Oil and Grease =10 mg/1
Daily monitoring for temperature.
Monthly monitoring for copper.
Weekly monitoring for pH
Quarterly chronic toxicity limit of 13% in March, June, September and December.
A max. flow of 2 MGD was used to calculate the IWC.
TOXICITY TESTING:
Chronic Toxicity at 13%: March, June, September and December.
SGL has passed all quarterly toxicity tests since March 2 00 1.
IWC calculated based using highest monthly flow of 2.0 MGD in 2003
Recommend renewal of chronic toxicity test at 13%.
COMPLIANCE SUMMARY:
Facility has no permit violations or exceedances since the last renewal.
REASONABLE POTENTIAL ANALYSIS
The following metal parameter is monitored in the NPDES permit: Copper.
Data for the copper was reported in the discharge monitoring reports (DMR) and a
RPA was done:
Reasonable potential analysis was conducted based on data from .January 2003
through June 2005. Results and data analysis are attached.
• Monthly monitoring should be continued for copper based on RPA.
Copper results had thirty (30) reported values. There was reasonable
potential to exceed the allowable acute concentration but not the allowable
chronic concentration for the NC action level. Monthly monitoring should
be continued. Facility is consistently passing toxicity test.
Other parameters that were detected in the priority pollutant analysis done July 6,
2005. There is only one data value for each parameter.
+ Chloroform =12 ug/l, believed to be present due to common laboratory
contamination. Chloroform is not used in any process at SGL Carbon. No
monitoring recommended
• Silver = 0.001 mg/1 (1 ug/1), this value does exceeds the allowable
concentration of 0.46 ug/1. However, this is an NC action level and SGL
Carbon has consistently passed its chronic toxicity test. Recommend annual
monitoring for silver.
• Lead = 0.025 mg/1 (25 ug/1) this value does not exceed the allowable of 193
ug/1. Lead is not believed to be a parameter of concern. Facility always
passes its toxicity test. Recommend annual monitoring for lead.

Selenium = 0.019 mg/I (19 ug/1) this value does not exceed allowable of 38.7
ug/l. Facility always passes its quarterly toxicity test. Recommend annual
monitoring for selenium.
Zinc = 0.019 mg/l (19 ug/1) this value does not exceed allowable of 387.1 ug/l.
Facility always passes its quarterly toxicity test. Recommend annual
monitoring.
INSTREAM MONITORING:
Monitoring for temperature instream should be continued.
PROPOSED CHANGES
+ Recommend that SGL Carbon no longer_ be categorized as a major industry
due to revised permit rating sheet score.
The addition of annual monitoring for lead, selenium, silver and zinc
based on presence in effluent. Since effluent is primarily noncontact
cooling water and has always pas§ed its toxicity test minimal monitoring
is recommended..

• Selenium = 0.019 mg/l (19 ug/1) this value does not exceed allowable of 38.7
ug/i. Facility always passes its quarterly toxicity test. Recommend annual
monitoring for selenium.
• Zinc = 0.019 mg/1 (19 ug/1) this value does not exceed allowable of 387.1 ug/l.
Facility always passes its quarterly toxicity test. Recommend annual
monitoring.
INSTREAM MONITORING:
Monitoring for temperature instream should be continued.
PROPOSED CHANGES
• Recommend that SGL Carbon no longer be categorized as a major industry
due to revised permit rating sheet score.
• The addition of annual monitoring for lead, selenium, silver and zinc
based on presence in effluent._ Since effluent is primarily noncontact
cooling water and has always Passed its toxicity test, minimal monitoring
is recommended..
PROPOSED SCHEDULE FOR PERMIT ISSUANCE:
Draft Permit to Public Notice: 08/31/2005
Permit Scheduled to Issue (est.): 10/24/2005

SGL Carbon. LLC - NPDES Permit Renewal information
Subject: SGL Carbon, LLC - NPDES Permit Renewal information
From: 'Tales" <[e-mail]>
Date: Thu, 23 Jun 2005 11:42:46 -0400
To: <[e-mail]>, <[e-mail]>
CC: "'Ives, Richard"' <[e-mail]>
Dear Ms. Knowell;
Please find attached several items of information we had discussed on the phone a few days ago regarding the
SGL Carbon, LLC NPDES permit renewal.
The following items we had discussed and the addressing of these items is provided below:
Category of SGL Carbon, LLC based on SIC code 3624
In addressing the SIC Code issue, I have attached a copy of the description from US DOL — OSHA of the
SIC Code 3624. The SIC code for this facility is correct and is specific to what SGL Carbon does. SIC 3624
— Carbon and Graphite Products applies to SGL Carbon as they are an establishment engaged in
manufacturing carbon and graphite electrodes for thermal and electrolytic uses. They are not engaged in
any electronics manufacturing or any type of electronic equipment. They should not be and are not a
categorical discharger under the electronic or electrical equipment manufacturing category. According to
Appendix A (SIC Code Cross Reference and Total and Human Health Toxicity Number) of the NPDES
Permit Rating Work Sheet, SIC Code 3624 Carbon and Graphite Products is not listed as a CFR categorical
industry. A copy of the applicable page of Appendix A is also attached. Based on these SIC Code
descriptions and the manufacturing process at SGL Carbon, LLC in Morganton, we are positive this is the
correct and accurate SIC for this facility and we are positive that this SGL Carbon, LLC facility is not subject
to any categorical NPDES discharge standards'for electronics or electrical equipment manufacturing.
Attachments: US DOL SIC Code Description for 3624 (PDF file)
Page of Appendix A to NPDES Permit Rating Work Sheet showing SIC Code 3624
2. Description of the process at the SGL Carbon, LLC, Morganton, NC facility,
The SGL Carbon, LLC facility in Morganton, NC produces carbon and graphite rods which are used solely
by the steel manufacturing industry as high temperature electrodes to heat steel up to 70000 C. The
process at this facility includes milling or grinding petroleum coke to obtain the correct particle size
distribution. This carbon black" milled petroleum coke powder is then mixed with coal tar pitch. This
mixture is formed into large cylindrical shaped rods and baked at high temperatures to form a carbon rod
that is solid and hard like concrete. Additional bulk density may be added to the carbon rods by added
impregnating the rods with petroleum pitch under pressure. The petroleum pitch impregnated rods may
then be baked again at about 800' C. This step of pitch impregnation and additional baking is only
performed as needed to add bulk density to rods. The final step in the production process is the
graphitization of the hard carbon rods. This step is performed by heating the carbon rods to about 24000 C
via high electrical current to graphitize the rods. The final products produced are large graphite rods which
have no leachable or volatile material properties. These graphitized rods are basically the same material as
a No. 2 pencil. Based on this process which only involves the mixing of raw materials and several baking
steps at high temperatures producing a nonhazardous and inert product, this facility is in no way involved in
electronics or electrical equipment manufacturing or is not an electronics categorical industry.
Attachments: SGL Carbon Process Description (PDF file)
3. Priority Pollutant Analysis for the NPDES discharge.
Discussion with SGL Carbon, LLC personnel did confirm that a priority pollutant analysis was performed at
the request of Jerry Miller during the previous NPDES permit renewal. SGL Carbon, LLC will perform a
priority pollutant analysis as requested for the purposes of this permit renewal. Sampling for this should be
completed some time within the next week or two and we expect to have sampling results hopefully within
one month from now. The priority pollutant analysis results will be forwarded to you and the NPDES Unit as
soon as the results are received.
1 of 3 8/ 15/2005 6:20 PM

SGL Carbon, LLC - NPDES Permit Renewal information
Several items of concern should be addressed regarding the priority pollutant analysis. Based on previous
analysis results at SGL Carbon and based on some recent priority pollutant analysis results performed by
other industries in Morganton, NC, there were several contaminates detected as a result of the local public
water treatment processes. These parameters include chloroform and several other chlorine water
treatment byproducts resulting from the treatment of public drinking tap water and byproducts of chlorinated
tap water.
Another parameter of concern is fluorine and fluorine related byproducts which are also a result of the
fluorination of tap water at the Morganton water treatment plant. Recent water quality reports on the City tap
water show fluoride in detectable levels that may present a false concern in a priority pollutant analysis.
SGL Carbon, LLC neither uses nor discharges any materials containing fluoride or fluorine products;
therefore SGL Carbon would attribute any fluoride or fluorine results on the priority pollutant analysis to the
tap water from the water treatment plant which is located less than 2 miles from the facility. We bring these
items to attention only because of our knowledge of other area facilities having these same issues arise
during their NPDES permit renewal process and the knowledge that certain contaminates are known to be
present in public potable tap water. This is especially of concern because most of our discharge is
noncontact cooling water which is obtained from the public tap water supply.
4. Classification of the facility as major or minor.
The final item that was discussed regarding the NPDES permit renewal was the question of whether or not
the SGL Carbon, LLC Morganton, NC facility was a major or minor facility. After reviewing the NPDES
Permit Rating Work Sheet issued by EPA it is our opinion that this facility is most likely a major facility.
Although some items on the six factors concerned could not be answered completely accurately either due
to lack of information or because they would have to be decided by NCDENR, our best estimates on the
score summary were between 70 and 120 depending on how some items were answered. On this basis,
and according to the worksheet of a score of 80 or above being a major facility, it is probable that this SGL
Carbon facility would be considered a major facility.

NPDES Permit Number: NC0005258
SIC Code: 3624 — Carbon and Graphite Products
I. Description of process at the SGL Carbon, LLC, Morganton, NC facility.
The SGL Carbon, LLC facility in Morganton, NC produces carbon and graphite rods which are
used solely by the steel manufacturing industry as high temperature electrodes to heat steel up to
7000" C. The process at this facility includes the following steps. The first step includes the
milling or grinding of petroleum coke to obtain a correct particle size distribution of the ground
material. This "carbon black" milled petroleum coke material is then mixed with coal tar pitch.
This mixture is formed into large cylindrical shaped rods and baked at high temperatures to form a
carbon rod that is solid and hard like concrete. Additional bulk density may be added to the
carbon rods by impregnating the rods with petroleum pitch under pressure. The petroleum pitch
impregnated rods may then be baked again at about 8000 C. This step of pitch impregnation and
additional baking is only performed as needed to add bulk density to the carbon rods. The final
step in the production process is the graphitization of the hardened baked carbon rods. This step
is performed by heating the carbon rods to about 24000 C via high electrical current to graphitize
the rods. The final products produced are large graphite rods which have no leachable or volatile
material properties. These graphitized rods are basically the same material as a No. 2 pencil.
II. Raw Materials: Petroleum Coke, coal tar pitch, and petroleum pitch
Ill. Process Description Outline:
1. Milling / grinding of petroleum coke.
2. Mixing of ground coke with coal tar pitch.
3. Forming / extrusion of cylindrical rods of the coke / coal tar pitch mix.
4. High temperature baking of rods to form a solid hard carbon rod.
5. If needed, the hard carbon rod is impregnated with petroleum pitch and baked again at
about 8000 C. This step adds bulk density to the rod.
6. Carbon rod is graphitized at high temperature of about 24000 C producing a graphite rod.

Jackie,
According to the Development Document for the final effluent
limitations, the "carbon and graphite" subcategory was excluded from
final regulation. It appears that the facility you referenced with
an
SIC code of 3624 would fall into this excluded subcategory, thus,
the
guidelines at 40 CFR 469 would not apply to this facility. The
reason
for the exclusion is "because pollutants are found only in trace
amounts
and in quantities too small to be effectively reduced by treatment."
Please let me know if this does not agree with your interpretation
of
the guidelines!
Sincerely,
Samantha Lewis

Re: Renewal Request and Amended Application for NPDES Permit Number NC0005258.
Dear Ms. Nowell;
The SGL Carbon, LLC facility located in Morganton, North Carolina request the renewal of NPDES
Permit Number NC0005258. We had previously submitted our renewal in July 2004. Because of an
oversight and some confusion on the definition of contact cooling water, we did not list any process
discharge in our original application submitted in July 2004. Please find enclosed the amended pages
2 and 3 of the Short Form - C permit renewal application as you requested.
Thank you for your consideration and timely renewal of this permit. If you have any further questions,
please contact me at your convenience.
Sincerely,
Richard Ives

Most of the discharge is from non -contact cooling water. There is some contact cools
water discharge from baking furnaces that utilize water seals to prevent combustion gas
emissions; however, there are no significant chemical additions to the discharge from this
process.. Also note that because facility stormdrains that are located throughout facility also
discharge to the same NPDES outfall, it is possible that some TSS, Oil & Grease, or copper
residuals maybe dischMed to the single NPDES outfall via stormwater runoff. These
discharlres_are_addressed in the NPDES Stormwater Discharge Permit NCS000009- _

Re: Request for additional information on Solids handling and disposal.
NPDES Permit Number NCO005258 Renewal Request and Application.
Dear Ms. Bryant;
We recently received a letter from the NPDES Unit regarding the permit renewal application we
submitted. Your office requested that an additional item was needed to complete the process of our
permit renewal. This item was in regards to solids handling and disposal, specifically, how often are
solids (sludge) removed from our facility and how are the solids disposed of after removal?
We were somewhat confused by this request since we do not have any sludge or solids removal
related to our wastewater discharge. Our answer to your inquiry is that we do not have any solids
(sludge) removal and no related disposal.
If you have any further questions regarding this issue please contact me at your convenience. Thank
you for your consideration and timely renewal of this permit.
Sincerely,
Richard Ives
