Notes for OCPSF and CWT Parameters
Should any annual monitoring result in detection of an OCPSF parameter contained in 40 CFR 414 Subpart I
(excluding metals) or CWT parameter contained in 40 CFR 437 Subpart D, then quarterly monitoring will begin
immediately for the detected pararneter(s). After four consecutive quarterly samples resulting in non -detection are
achieved, the monitoring frequency will revert to annually.
When an approved analytical protocol with the appropriate minimum detection level is followed and a result of "non -
detectable" or "below quantitation limit" is obtained, the permittee will be considered to be in compliance with the
numerical permit limit for that pollutant.
A. (3) CHRONIC TOXICITY PERMIT LIMIT (Quarterly)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia
dubia at an effluent concentration of 1.8%.
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 II 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 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 defmition 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: North Carolina Division of Water Quality
Environmental Sciences Section
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.
10

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 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
monitoring.
A. (4) TOTAL PHOSPHORUS AND TOTAL NITROGEN MONITORING
The Permittee shall calculate a 12-month rolling average mass loading as the sum of monthly loadings, according to the
following equations:
(1) Monthly Average (pounds/day) = TP x Qw x 8.34
where:
TP = the arithmetic average of total phosphorus concentrations (mg/L) obtained via composite samples (either daily, weekly, or
monthly average values) collected during the month
Qw = the average daily waste flow (MGD) for the month
8.34 =conversion factor, from (mg/L x MGD) to pounds
The 12-month rolling average mass loading is defined as the sum of the monthly average loadings for the previous 12 months
inclusive of the reporting month:
12
(2) 12-Month Mass Loading (pounds/day)= TPma =12 (inclusive of reporting month)
Where:
TPma = the total phosphorus monthly average mass loading (calculated above).
Total Nitrogen is to be calculated using the same method.
The monthly average and 12-month average mass loadings shall be reported on the attached worksheet and submitted with
the discharge monitoring report for Clariant Corporation. The first worksheet is due with the discharge monitoring report, 12
months from the effective date of the total phosphorus and total nitrogen limits. In the interim period between the effective
date and the requirement to submit the attached worksheet, the total phosphorus and total nitrogen monthly average mass
loadings should be reported on the discharge monitoring report for the respective facility.
The Permittee shall report the total phosphorus and total nitrogen concentrations for each sample on the discharge monitoring
report. Reporting of and compliance with the phosphorus and nitrogen limits shall be done on a monthly basis.

a
A. (4) STAGING REQUIREMENTS (APPLICABLE APRIL 1— OCTOBER 31)
The operating day runs from 7:00 am to 7:00 am. Each day, the permittee will calculate a running daily average
stream flow as determined by turbine operation at Mountain Island Dam, leakage at the dam (80 cfs), and the
7Q10 flow of Dutchman's Creek (15 cfs). Effluent release is to be controlled such that projected release of BOD
and ammonia, using the most recent analytical values for these parameters, will not exceed the value given in the
following formulas:
(1) When the daily river flow is calculated to be < or = 175 cfs: BOD5 + 0.54(NH3-N) <=566.4 pounds/day
(2) When daily average river flow is calculated to be >175 cfs but < or = 250 cfs: BOD5 + 0.54(NH3-N) <=1044
pounds/day
The attached additional DMR sheet (see next page) shall be used to monitor compliance with BOD and NH3
staging requirements during the summer (April 1— October 31)

POINT SOURCE BRANCH
Clariant has reviewed the draft NPDES permit we received recently and offer the following
comments:
The Oil & Grease parameter is new to the permit. It is being added to the permit because
Clariant receives wastes that fall under the Oils Treatment and Recovery category (Subpart B) of
the Centralized Waste Treatment Effluent Guidelines. The Tier I limits in the permit are very
low based on the small quantity of oily wastewater that Clariant currently receives. We have
preliminary indications that we could have trouble meeting this Oil & Grease limit, but need to
do additional testing. If we determine we can not meet the draft limit, our most likely course of
action will be to discontinue the oily waste portion of our wastewater business so that we are not
subject to the oil & grease limitation. We plan to collect additional oil & grease data and contact
you on this issue in the near future to discuss options.
The Tier 2 values for ammonia on page 4 do not reflect the new limits. The values should be
Monthly Average of 574.5 lbs instead of 618.0 lbs and Daily Max of 861.8 lbs instead of 927.0
lbs.
On page 9, under the Tier 2 CWT Parameters, there was a typo on the Daily Max number for
2,4,6-Trichlorophenol. It should be 0.65 instead of 1.65.
On page 12, the paragraph at the top of the page that requires a BAT study should be deleted. - vk b`tA.d1C°�
This requirement was carried forward from the existing permit. The study has already been
completed.

-- AAA at 2
On Page 14, Case 3 River Flow is unnecessary. Only two river flow conditions are covered under
Section A.(5). I believe the intent was to drop Case 3 some years ago as the regular technology
based limits became lower.
On Page 2 of the Fact Sheet, there is a typographical error in the middle of the page. The flow
number for OCPSF parameters under Tier 2 should be 0.584 MGD instead of 0.574 MGD.
Thank you for this opportunity to comment on the draft permit. Please contact me at 704-822-
2702 if you have any questions concerning our comments. As I mentioned earlier, I will be
contacting you soon to discuss the Oil & Grease issue further.

RE: Notification of Intent to Renew a NPDES Wastewater Permit for the Clariant Corporation
(NC0004375) dated March 16, 2005.
Dear Ms. Bryant:
This letter contains comments regarding the above -proposed NPDES permit renewal,
which would continue the discharge of treated wastewater into the Catawba River.
According to DHEC monitoring data, Lake Wylie is impaired by copper levels above the
Mill Creek arm at the end of road S-46-557. South Carolina's standard for copper is 2.9 ug/I.
In addition, Lake Wylie (Crowders Creek arm at SC highways 49 and 274) and the
Catawba River (at South Carolina Highway 21) are impaired by fecal coliform bacteria. South
Carolina's standards for fecal coliform in the Catawba River are "not to exceed a geometric mean
of 200/100m1 based on five day consecutive samples during any 30 day period; nor shall more
than 10% of the total samples examined during any 30 day period exceed 400/100ml."
Please ensure that any permitted activities will not contribute to violations of South
Carolina standards. Please send a copy of the draft permit and permit rationale to Mike
Montebello, South Carolina Department of Health and Environmental Control (DHEC), Bureau of
Water, 2600 Bull St., Columbia, South Carolina 29201. Thank you for considering these
comments when reviewing, revising, and issuing this permit. If you need more information,
please contact Mark Giffin at [phone] or [e-mail] for assistance.

Summary
Clariant operates a specialty chemical manufacturing facility in Mount Holly. Wastewater from the
facility is treated in an on -site WWTP. The existing permit is based on the OCPSF and CWT
(centralized waste treatment) effluent guidelines.
The facility has been a specialty chemical and dye -manufacturing site since 1937. As a result of
historical operations, the facility is included on the National Priorities List due to organic contained
in surface water and groundwater from the site. Stormwater from the facility is therefore treated in
the on -site WWTP in addition to the OCPSF process wastewater, CWT process wastewater, and
domestic wastewater from current on -site manufacturing operations. The WWTP also receives
groundwater from a groundwater pump and treat system and leachate from an active on -site landfill
cell. Recently, dye -manufacturing operations have been shutdown at the facility. As portions of the
facility become inactive, Clariant is developing the facility as an industrial park. The following two
tenant operations are currently located at the facility with the treatment of the resulting process
wastewaters in the on -site WWTP:
Fact Sheet
NPDES Renewal (NC0082295)
Page 1

• SCR -Tech — A non -categorical operation that regenerates NOx air pollution control catalyst
• Monark Industrial Services, Inc. — A non -categorical operation that solidifies liquid and
semi -solid wastes.
Since Clariant is developing the facility as an industrial park, future wastewater sources will occur.
In order to account for these future wastewater sources in the permit effluent limits, a tiered
approach to developing the limits was used. The proposed limits for both conventional and non -
conventional parameters are presented in two tiers, Tier 1, and Tier 2. The Tier 1 limits are based
on wastewater flow from existing and planned wastewater sources. The Tier 2 limits are based on
wastewater flow not only from existing and planned wastewater sources, but also from future
wastewater sources. Tier 2 limits become effective when any new wastewater source, beyond the
existing and planned wastewater sources, is added.
Facility has no fecal coliform limit due to the very minor contribution of sanitary wastewater flow.
Facility has not violated Cu and Zn limits over the past four years.
Technology Based Effluent Limit Development
Conventional parameters have been calculated based on the guidelines specified in the Table 3-1
(attached). Flow numbers for calculation were taken from the Table 2-2 (attached). The following
effluent guidelines were used to calculate permit limits:
• OCPSF parameters — 40 CFR Part 414 (Tier 1— 0.474 MGD; Tier 2 — 0.584 MGD)
• CWT parameters — 40 CFR part 437 (subparts B and C) (Tier 1— 0.278 MGD; Tier 2 —
0.505 MGD)
The results of these calculations are generally more stringent than the limits in the current permit.
All the calculations are attached. For CWT calculations wastes for subparts B and C were added
together, and effluent guidelines from both subparts were applied to the final number. In case
where the same parameter has different allocation in two subparts, the more stringent allocation
was used for calculations.
Limits for Total Nitrogen and Total Phosphorus have been established based on the results
of the BAT study. Monthly average limit for NH3-N was established as the 95th percentile
effluent load, daily maximum limit was calculated using 1.5 multiplier.
Toxicity Testing
Current Requirement: Quarterly Chronic Toxicity @ 1.8% MAR, JUN, SEP, DEC
Recommended Requirement: Quarterly Chronic Toxicity @ 1.8% MAR, JUN, SEP, DEC
The facility has been consistently passing its WET tests during previous permit cycle with two
exceptions. Subsequent tests have passed.
Compliance Summary
DMRs have been reviewed for the period January 2001 through January 2005. Facility has a good
compliance record. During the review period, the following NOVs (notices of violation) have been
issued: 02/23/04 — Tox. test failure, 02/19/04 — BOD, 02/26/03 — Tox. test failure, 08/08/03 - TSS.
A compliance evaluation inspection conducted on May 12, 2004 determined that facility is in
compliance. The facility has been on EPA Watch List for vanadium. The source of vanadium was
identified (an improperly connected sump drain in the SCR -Tech building) and removed.
Fact Sheet
NPDES Renewal (NC0082295)
Page 2

Instream Monitoring
Instream monitoring is required DO, pH, temperature and conductivity. Facility is not likely to
strongly influence water quality due to the high dilution ratio.
Proposed Changes
• Monitoring Frequencies: No changes are proposed.
• Limits: Limits for OCPSF, CWT and conventional parameters have been
recalculated based on the reevaluation of projected flows. Oil and Grease limit has
been added in accordance to the federal guidelines requirements. The following
parameters have been eliminated from the permit based on the recent revisions in
Federal Guidelines for Centralized Waste Treatment and changes to the categories
of waste being accepted at the facility: Antimony, Barium, Molybdenum, Selenium,
Silver, Titanium, Vanadium, Aniline, and 2,3-Dichloroaniline. Limits for Total
Nitrogen (limit reduced) and Total Phosphorus (limit increased) have been
established based on the results of the BAT study.

Notes for OCPSF and C' F Parameters
Should any annual monitoring result in detection of an OCPSF parameter contained in 40 CFR 414 Subpart I
(excluding metals) or CW T parameter contained in 40 CFR 437 Subpart D, then quarterly monitoring will begin
immediately for the detected parameter(s). After four consecutive quarterly samples resulting in non -detection are
achieved, the monitoring frequencywill revert to annually.
When an approved analytical protocol with the appropriate minimum detection level is followed and a result of "non -
detectable" or "below quantitation limit" is obtained, the permittee will be considered to be in compliance with the
numerical permit limit for that pollutant.
A. (3) CHRONIC TOXICITY PERMIT LIMIT (Quarterly)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia
dubia at an effluent concentration of 1.8%.
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 II 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 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: North Carolina Division of Water Quality
Environmental Sciences Section
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.
10

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 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
monitoring.
A. (4) TOTAL PHOSPHORUS AND TOTAL NITROGEN MONITORING
The Permittee shall calculate a 12-month rolling average mass loading as the sum of monthly loadings, according to the
following equations:
(1) Monthly Average (pounds/day) = TP x Qw x 8.34
where:
TP = the arithmetic average of total phosphorus concentrations (mg/L) obtained via composite samples (either daily, weekly, or
monthly average values) collected during the month
Qw = the average daily waste flow (MGD) for the month
8.34 =conversion factor, from (mg/L x MGD) to pounds
The 12-month rolling average mass loading is defined as the sum of the monthly average loadings for the previous 12 months
inclusive of the reporting month:
12
(2) 12-Month Mass Loading (pounds/day)= E TPma =12 (inclusive of reporting month)
1
Where:
TPma = the total phosphorus monthly average mass loading (calculated above).
Total Nitrogen is to be calculated using the same method.
The monthly average and 12-month average mass loadings shall be reported on the attached worksheet and submitted with
the discharge monitoring report for Clariant Corporation. The first worksheet is due with the discharge monitoring report, 12
months from the effective date of the total phosphorus and total nitrogen limits. In the interim period between the effective
date and the requirement to submit the attached worksheet, the total phosphorus and total nitrogen monthly average mass
loadings should be reported on the discharge monitoring report for the respective facility.
The Permittee shall report the total phosphorus and total nitrogen concentrations for each sample on the discharge monitoring
report. Reporting of and compliance with the phosphorus and nitrogen limits shall be done on a monthly basis.
11

A. (4) TOTAL PHOSPHORUS AND TOTAL NITROGEN MONITORING
(continued)
The permittee shall be required to perform a study which determines monthly average limits for total phosphorus
(TP) and total nitrogen (TN) which can be met through the application of best available technology (BAT) that is
economically achievable. The study shall be based on 12 months of effluent monitoring data collected from
January 1, 2003 to December 31, 2003. The BAT study report shall be submitted to the NCDWQ for approval by
July 1, 2004 and the division will apply BAT limits for TP and TN to the permittee's discharge based on the
results of this study and the performance of other similar plants. The TP and TN limitations shown in A. (1) are
interim limits which shall remain in effect until the BAT study is completed and BAT limits for TP and TN are
established by the Division.
A. (5) STAGING REQUIREMENTS (APPLICABLE APRIL 1— OCI'OBER 31)
The operating day runs from 7:00 am to 7:00 am. Each day, the permittee will calculate a running daily average
stream flow as determined by turbine operation at Mountain Island Dam, leakage at the dam (80 cfs), and the
7Q10 flow of Dutchman's Creek (15 cfs). Effluent release is to be controlled such that projected release of BOD
and ammonia, using the most recent analytical values for these parameters, will not exceed the value given in the
following formulas:
(1) When the daily river flow is calculated to be < or = 175 cfs: BOD5 + 0.54(NH3-N) <=566.4 pounds/day
(2) When daily average river flow is calculated to be >175 cfs but < or = 250 cfs: BOD5 + 0.54(NH3-N) <=1044
pounds/day
The attached additional DMR sheet (see next page) shall be used to monitor compliance with BOD and NH3
staging requirements during the summer (April 1 — October 31)

XI. MAP
Attach to this application a topographic map of the area extending to at least one mile beyond property boundaries. The map must
show the outline of the facility, the location of each of its existing and proposed intake and discharge structures, each of its
hazardous waste treatment, storage, or disposal facilities, and each well where it injects fluids underground. Include all springs,
rivers and other surface water bodies in the ma. area. See instructions for .recise re• uirements.
XII. NATURE OF BUSINESS •rovide a brief descri•tion
The Clariant Corporation operates a chemicals production facility and centralized waste treatment (CWT) plant
near Mount Holly, North Carolina (Clariant-Mt. Holly East Plant). Wastewater from the facility and from off -site
locations are treated in an on -site wastewater treatment plant (WWTP) and the treated wastewaters are
discharged to the Catawba River under NPDES Permit No. NC0004375. The current NPDES permit became
effective on March 1, 2003. This permit was issued by the North Carolina Department of Environment and Natural
Resources (NCDENR). The facility had been a specialty chemical and dye manufacturing site since 1937. In
recent years a number of the production units have shut down and the latest NPDES permit authorizes operation
of a centralized waste treatment system. The treated wastewaters include 1) CWT wastewaters from off -site
manufacting operations, hauled to the Clariant facility; 2) Stormwater from the facility; 3) Process wastewater and
domestic wastewater from current on -site manufacturing operations; and 4) The groundwater from a
groundwater pump and treat system and leachate from an active on -site landfill cell. In addition to treating
hauled -in wastes in the CWT operations, Clariant has developed the facility as an industrial park for compatible
industrial operations. To date, two(2) tenants have operations at the facility with one producing process
wastewaters for treatment in the on -site WWTP.

B. Provide a narrative description of significant materials that are currently or in the past three years have been treated, stored or disposed
in a manner to allow exposure to storm water; method of treatment, storage, or disposal; past and present materials management
practices employed to minimize contact by these materials with storm water runoff; materials loading and access areas; and the location,
manner, and frequency in which pesticides, herbicides, soil conditioners, and fertilizers are applied.
Chemicals are stored in warehouses and production takes place in buildings. Consequently, chemicals are
not exposed to stormwater. Management practices include movement of packaged materials via flatbed truck
and unloading of the packages onto covered docks at the building locations. Fertilizer is applied to some
lawn areas. Herbicides are used to control weed growth through blacktop surfaces and along rail spur
locations. Application of chemicals is done on dry days in early summer. Stormwater from the production
area is collected in numerous catch basins located throughout the facility, which connect directly to the
process wastewater sewer collection system. The combined process wastewater and stormwater are treated
in the on -site WWTP (see Form 1 and Form 2C). Stormwater from non -production areas is permitted under an
individual stormwater permit (No. NC000037) and is not part of this NPDES permit application.
C. For each outfall, provide the location and a description of existing structural and nonstructural control measures to reduce pollutants in
storm water runoff; and a description of the treatment the storm water receives, including the schedule and type of maintenance for
control and treatment measures and the ultimate disposal of any solid or fluid wastes other than by discharge.

We are submitting three (3) copies of the attached permit application and permit documents for
renewal of the subject NPDES permit for the Clariant-Mt. Holly East facility. It is our
understanding that no fee is required by the Division since the documents being submitted are for
renewal of the permit.
BACKGROUND
Clariant operates a specialty chemical and dye manufacturing facility in Mount Holly, North
Carolina (Clariant-Mt. Holly East Plant). Wastewater from the facility is treated in an on -site
wastewater treatment plant (WWTP). The existing NPDES permit is based on OCPSF and CWT
effluent guidelines.
The facility has been a specialty chemical and dye manufacturing site since 1937. As a result of
historical operations, the facility is included on the National Priorities List due to organic
contaminants contained in surface water and groundwater from the site. Stormwater from the
facility is therefore treated in the on -site WWTP in addition to the OCPSF process wastewater,
CWT process wastewater, and domestic wastewater from current on -site manufacturing
operations. The WWTP also receives groundwater from a groundwater pump and treat system
and leachate from an active on -site landfill cell.

2
Due to the recent decline in the US textile industry, dye manufacturing operations have been
shutdown at the Clariant-Mt. Holly East facility. However, OCPSF activities related to on -site
manufacturing of specialty chemicals and warehousing operations remain active at this time.
Treatment of leachate, groundwater and stormwater from the facility are also continuing. As
portions of the facility become inactive, Clariant is developing the facility as an industrial park
for compatible industrial operations. The following two (2) tenant operations are currently
located at the facility with the treatment of the resulting process wastewaters in the on -site
WWTP:
• SCR -Tech — A non -categorical operation that regenerates NO,, air pollution control
catalyst; and
• Monark Industrial Services, Inc. — A non -categorical operation that solidifies liquid
and semi -solid wastes.
Clariant also plans to add additional compatible industrial tenant operations in available on -site
areas. Wastewater from the additional tenants will also be treated in the on -site WWTP.
With the changes in dye manufacturing and inclusion of the wastewaters described above, the
requested permit renewal will result in a net reduction in the currently allowed wasteload
discharge from the Clariant-Mt. Holly East facility.
Application Package
The application package for the permit renewal and modification includes the following
documents:
• EPA Form 1— General Information;
• EPA Form 2C NPDES — Existing Manufacturing, Commercial, Mining and
S i lvicultural Operations;
• EPA Form 2F NPDES — Stormwater Discharges Associated with Industrial Activity;
• Application Support Document; and
• Suggested Draft permit.
We are also emailing an electronic copy of the suggested draft permit to your attention.

3
We appreciate the Divisions' cooperation and assistance with this matter. We would appreciate
the opportunity to meet with you to discuss the application documents and our plans for the
Clariant-Mt. Holly East facility. We will call your office within the next two weeks to schedule
a mutually convenient meeting date. In the meantime, please feel free to call either Ned Fiss
with AWARE Environmental Inc. at [phone] or myself at [phone] if you have
any questions or desire additional information.

Re: BAT Evaluations for Control of Nutrient Discharges
Clariant-Mt. Holly East Plant
NPDES Permit No. NC0004375
Dear Mr. Chernikov:
SEC 9 2004 J
POINT SOURCE ALITY
-RANCH
As requested in our September 9, 2004 meeting, AWARE Environmental Inc. (AEI), on behalf
of Clariant Corporation, is submitting the following information regarding our evaluations of
biological phosphorus removal (BPR) as best available technology economically achievable
(BAT) for control of total phosphorus (TP) discharges. Our findings are presented below.
BACKGROUND
Clariant operates an organic chemicals production (OCPSF) facility and centralized waste
treatment (CWT) plant near Mount Holly, North Carolina (Clariant-Mt. Holly East Plant).
Wastewater from the facility and from off -site locations are treated in an on -site wastewater
treatment plant (WWTP) and the treated wastewaters are discharged to the Catawba River
under NPDES Permit No. NC0004375. The current NPDES permit became effective on
March 1, 2003. This permit was issued by the North Carolina Department of Environment
and Natural Resources (NCDENR).
The facility had been a specialty chemical and dye manufacturing site since 1937. In recent
years a number of the production units have shut down and the latest NPDES permit authorizes
operation of a centralized waste treatment system.
The treated wastewaters include:
9305 MONROE ROAD • SUITE J • CHARLOTTE, N.C. 28270-1490 • TELEPHONE [phone] • FAX [phone]

1. Centralized Waste Treatment (CWT) wastewaters from off -site manufacturing
operations, hauled to the Clariant facility;
2. Stormwater from the facility;
3. Process wastewater and domestic wastewater from current on -site manufacturing
operations; and
4. The groundwater from a groundwater pump and treat system and leachate from an
active on -site landfill cell.
In addition to treating hauled -in wastes in the centralized waste treatment operations, Clariant
has developed the facility as an industrial park for compatible industrial operations. To date,
one (1) new tenant has operations at the facility with treatment of resulting process wastewaters
in the on -site WWTP.
A requirement which was contained in the March 2003 NPDES permit for the Clariant facility
was that Clariant update the BAT evaluation for total nitrogen and total phosphorus. The
results of that evaluation were included in an AEI June 2004 report entitled "Update of the
Evaluation of Best Available Technology Economically Available (BAT) for Control of
Nutrient Discharges".
ANALYSIS OF PHOSPHORUS BAT
The analysis of phosphorus BAT reviewed the phosphorus discharge from the Clariant facility
and treatment altematives for additional phosphorus removal. Clariant does not add
phosphorus to its wastewater treatment plant for bacteria growth and none of the materials at
the Clariant facility are known to contain any significant levels of phosphorus. However, as a
CWT facility, it appears that there are periodic phosphorus wasteloads contained in the CWT
wastewaters hauled to the Clariant site for treatment.
A statistical analysis of the effluent total phosphorus which was measured during the BAT
study is shown in Figure 1. This indicates that the total phosphorus concentration in the
Clariant WWTP effluent is highly variable due to CWT contributions and can range from less

than 1 mg/1 to 16 mg/1. The BAT study considered alternatives for total phosphorus reduction.
This included biological and chemical treatment processes. The process selected for further
evaluation was chemical precipitation. Chemical precipitation was selected for removal of
phosphorus from the Clariant wastewater because of its simplicity and demonstrated
performance for a wide range of wastewaters for a long period of time. The biological
phosphorus removal (BPR) process was considered but did not appear to be viable for the
Clariant facility.
BPR is accomplished in activated sludge processes by selecting for phosphorus accumulating
organisms (PAOs) through the use of an anaerobic selector. Anaerobic conditions refers to the
condition of zero dissolved oxygen and zero nitrate (NO3-N). Under anaerobic conditions,
most activated sludge organisms are not able to uptake and utilize organic material due to the
lack of an available electron acceptor (i.e. the lack of oxygen or NO3-N) to derive energy.
The PAOs are facultative heterotrophic bacteria (acinetobacter) which are able to absorb and
store soluble organic material as polyhdyroxy-alkanoates (PHAs). The PAOs specifically
require volatile fatty acids (VFAs) (such as acetate) as the organic substrate for this reaction.
Energy for this process is derived in part from the cleavage of internally stored polyphosphate.
This reaction results in a release of ortho-phosphate by the PAOs in the anaerobic zone.
When the PAOs reach the oxic (aerated) zone the organisms utilize dissolved oxygen to oxidize
the stored organic material (PHA) for energy. During this phase the PAOs also take in
dissolved phosphate from solution and synthesize polyphosphate for use later as an energy
source for substrate uptake in the anaerobic zone. Due to the growth of the organisms, the
uptake of phosphorus generally exceeds the amount released in the anaerobic zone, resulting in
a net removal of phosphorus through accumulation in the biological solids and wasting of
sludge from the biological process.
Biological processes are also responsible for nitrogen removal via nitrification and
denitrification. Nitrification refers to the biological oxidation of ammonia (NH3-N) to nitrate
4

(NO3-N). Nitrification is accomplished under aerobic conditions by autotrophic nitrifying
bacteria. Denitrification refers to removal of nitrogen from the wastewater through reduction
of NO3-N to nitrogen gas (N2), which is released to the atmosphere. Denitrification is
performed by heterotrophic bacteria under zero dissolved oxygen conditions in order to utilize
BOD5 as food using NO3-N as the source of oxygen (electron acceptor).
In the Clariant WWTP, both nitrification and denitrification are accomplished in the activated
sludge aeration basin by keeping the MLSS levels in excess of 5,000 mg/1 and maintaining
aeration DO concentrations at the 1 to 2 mg/1 level. The provision of a jet mixing system with
independent aeration provided by floating mechanical aerators allows balancing of the process
for optimal nitrification/denitrification.
PAOs specifically use VFAs as the carbon source for the storage of PHA in the anaerobic
stage. Therefore, provision of VFAs is critical to the success of the BPR process. VFAs are
normally present in municipal WWTP influents as a result of fermentation of complex organics
and solids in the wastewater collection system. However, where influent VFA content is low
or varies significantly, such as occurs in the Clariant wastewater, then acetic acid addition
would be required in order to provide sufficient VFA's for the BPR process.
In evaluating the Clariant treatment alternatives for phosphorus removal, it is AEI's opinion
that it would be extremely difficult to use biological phosphorus removal to treat a CWT
wastewater. An anaerobic activated sludge basin would have to be constructed ahead of the
existing aerobic/anoxic basin along with facilities for acetic acid storage and feed. The
biological process of BPR is not well -suited for highly variable phosphorus loads such as those
resulting from incoming CWT loads. Since chemical phosphorus precipitation can be easily
turned -up and/or turned -down with varying phosphorus loads, it was determined that the
chemical precipitation process is a more viable method of removing phosphorus from the CWT
wastewaters and can be better adapted to the Clariant facility.

From: Sergei Chernikov
Subject: Update of the Evaluation of BAT for Control of Nutrient Discharges
Clariant Corporation
I have reviewed the BAT studies for the Clariant Corporation, my comments are
summarized below:
1) The most recent study conducted by Aware Environmental has considered some
of the comments by the NPDES staff regarding their previous study and made
appropriate adjustments to the BAT study. However, consultants did not evaluate
specialized bacteria treatment option and biological nutrient removal option.
2) The study indicated that increasing MLSS to more than 5,000 mg/L and
maintaining DO level at the 1-2 mg/L would result in the significant improvement
of nitrogen removal efficiency (-30%). The new annual average TN limit would
be 318.5 lbs/day, compared to the existing limit of 441 lbs/day. Although
biological nitrogen removal was not considered, the cost of this alternative is very
likely to render it unfeasible. Nevertheless, it would have been reasonable to
include some cost estimates for constructing biological nutrient removal system.
3) The study indicated that nitrogen removal is a temperature dependent process and
summer nitrogen concentration in the effluent is almost order of magnitude lower
than winter concentration. Therefore, regulation of the aeration basin temperature
should be considered as one of the alternatives.
4) Total phosphorus BAT was based on chemical precipitation method, ferric
chloride was found to be the most effective flocculant. Biological removal was
not considered. The study did not explain the reason for using the cost of
phosphorus removal for the municipal systems. The industrial facilities would
have been more appropriate for the comparison purposes. The process for
determining phosphorus BAT is not clear. The figure used for this purpose
appears to have an asymptotic curve that doesn't have a very good fit. The source
of data points is not clear and R2 value is not presented. 1), 32, ttoic

We've reviewed the BAT studies for the above referenced facilities and provide the comments bulleted below.
• The studies did not evaluate total nitrogen reduction. They only evaluated the removal of Total Non -
Refractory Nitrogen (TNN). The basic assumption is that there is a portion of nitrogen in the effluent that is
not biological treated and, therefore, is not available for biological utilization in the receiving stream. This is
a flawed argument for several reasons. First, the treatment system wasn't originally designed to remove total
nitrogen. Second, the treatment system is not representative of the environment. Third, there was no data
provided supporting the claim that the nitrogen is not available for biological uptake. The report says
nothing of the fate and transport of the so-called refractory nitrogen in the receiving stream.
• The reports indicate that, based on OCPSF guidance, the existing facilities are considered BAT facilities.
Although this may be true for the parameters regulated by the OCPSF rules, nutrients are not regulated by
these rules. The fact that the facilities may be considered BAT facilities by the OCPSF rules is irrelevant.
• The reports did not evaluate some of the more obvious treatment alternatives such as anaerobic treatment
for phosphorus and organic nitrogen removal.
• The cost estimates were inadequate. None of the costs were itemized. It is absolutely critical that costs be
thoroughly itemized in order to evaluate alternatives. Additionally, comparing municipal facilities to these
facilities is analogous to comparing apples to oranges. Municipal facilities often have the concept of
economy of scale working in their favor.
• The studies only evaluated optimization for nitrogen and phosphorus additions. They did not evaluate
optimization of alternative operating parameters, of which there are many. The facilities appear to be
operating the existing plants as if they are treating domestic wastewater (3500 mg/L MLSS, 6-9 mg/L reactor
DO, sludge age of 32 days, pH of 7.0, F/M of 0.46).

• Although the facilities have reviewed pollution prevention and waste minimization, they have apparently not
evaluated raw material substitution. Additionally, we respect the fact that there is often a lack of
communication between production staff and treatment staff. We maintain however, that improved
communication can only help to reduce and or predict the variability of the waste stream and enhance
wastewater treatment over the long term.
• Several recently published studies on di-azo dye degradation have shown promise with using a specialized
treatment organism. One of note employed a fungus for degradation. The studies did not attempt to
evaluate the opportunities of specialized bug treatment.
In summary, we feel that the studies were poorly prepared. Additionally, there seems to be a significant lack of
detail.

Hi Jackie. I'm doing well for an old man on a dozen prescriptions.
Listen! Listen! Can you hear it? That's retirement calling out to
me. It promises no more Gleason to contend with.
Apparently, effective in 2/04 Clariant is subject to the Tier 2
Limits/Monitoring. If Charles Weaver changes BIMS accordingly,
there will be no perception of violations.

Hello Richard,
Hope that you are doing well. Bet you thought I'd ignored you on
this on. Not so!
Clariant should be monitoring monthly for phenol as listed on the
effluent pages A(1) a & b, but the limit that should be applied
should the monthly average limit and daily maximum limits listed
in A(2) c & f. The frequency should probably be changed in A(2)
c & f, like mercury, chromium and zinc were changed to monthly on
these pages. Hope this straightens it out. Will be sending out a
correction page shortly.
What did they violate in February 2004?
Jackie

Re: NPDES Permit Number NC0004375; Addition of New Waste Source to the Site
Wastewater Treatment Plant
Dear Ms. Nowell and Mr. Gleason;
As required by Section A. (7) of our NPDES permit, I wish to inform you that an
additional on -site wastewater source will begin operations on January 22, 2004. The new source
is an oily water separation process that will be operated by Clariant. It is located in an operating
area of one of the old manufacturing units.
Clariant had originally contracted with Remedial Services Incorporated, RSI, of Satsuma,
Alabama for this work. Because of management problems and construction cost issues, RSI
withdrew from the contract. As a result, Clariant has decided to run the process itself.
Clariant will begin reporting effluent data in compliance with Tier 2 effluent limitations
and monitoring requirements effective January 26, 2004.
If there is any additional information that is needed by the Division, please let me know.
My phone number is 704-822-2787. My email address is [e-mail].
Sincerely;
l‘i7/
Gary P. Sanderson, P.E.
Plant Services Manager
