Subject: Issuance of NPDES Permit NC0004375
Mt. Holly East Plant
Mecklenburg County
Dear Mr. Sanderson:
Division personnel have reviewed and approved your application for renewal of the subject permit. Accordingly, we
are forwarding the attached NPDES discharge permit. This permit is issued pursuant to the requirements of North
Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S.
Environmental Protection Agency dated May 9,1994 (or as subsequently amended.)
Clariant Corporation should be aware that the Division will re-evaluate the justification for the entire 3.9 MGD flow
requirement upon the next renewal of this permit in 2005.
The following modifications from the draft permit previously sent to you have been included in this final
permit:
• Facility information on the map has been corrected to show the U.S.G.S. Quad # as F14SE and the stream
classification as WS-IV CA.
• There is a modification in the footnotes of Section A. (6) Effluent Pollutant Scan. Two copies of the test result
report, DMR-PPA1, shall be submitted along with the DMR forms to the Division's Central Files. A copy of the
form is attached to the permit.
These conditions from the draft permit remain in the final permit.
• Effluent limitations for BOD and Total Suspended Solids have been modified based on the revision of waste
flows used for development of the allocations for OCPSF, non -categorical and centralized waste treatment waste
streams. Effluent limitations have been reduced due to a smaller flow (not design capacity) being used for
allocation development. The application support document submitted by Clariant describes the allocation
process.
• Tiered limitations have been placed in the permit. Tier 1 limits are effective for existing wastewater sources. Tier
2 limits become effective when any additional wastewater sources are added. Special condition A. (7) requires
that Clariant notify the Division at least fourteen days prior to the addition of any new wastewater sources.
• The effluent limitation for NH3 as N has been revised slightly downward to a mass -based limit of 618
pounds/day (monthly average) and 927 pounds/day (daily maximum). In the past, the NH3 limit has been
allocated based on secondary treatment of the effluent discharge.

Permit NC0004375
• Monthly monitoring for manganese, sulfates, chlorides, MBAS and iron has been reduced to quarterly
monitoring. The reduction was based on the results of reasonable potential analyses that indicated that the
relevant NC water quality standards would not be violated by the effluent discharge. A limitation is not required
for these parameters but due to the nature of the discharge, effluent monitoring is still required.
• Monthly monitoring for chromium and zinc has been added to the permit based on new wastewater streams from
Seaboard Container Cleaning and SCR -Tech.
• Effluent limitations for total nitrogen and total phosphorus have been added to the permit based on the Catawba
River Basin Management Plan for nutrient protection in the Lake Wylie watershed. These are interim limits based
on current information from the facility. A nutrient worksheet is attached for recording the monthly average
total nitrogen and total phosphorus data to be submitted to DWQ.
• A special condition has been added to the permit that will require Clariant to conduct a BAT study for the
development of more accurate nutrient limits in 2003.
• Mercury continues to be a water quality concern throughout North Carolina. NPDES permittees have worked
with the State to reduce potential risks from this pollutant, including tasks associated with collecting and reporting
more accurate data. The most commonly used laboratory analysis (EPA Method 245.1) has a detection limit of
0.2 µg/L while the current water quality standard is an order of magnitude lower at 0.012 µg/L. A more recently
approved analytical test (EPA Method 1631) should produce a detection limit below the level of the standard.
This will allow the Division to assess potential water quality impacts from discharges more accurately. Therefore,
beginning on or before September 1. 2003, you will be required to begin using EPA Method 1631 when analyzing
for mercury. Please note that mercury shall be measured as a grab sample.
• Instream monitoring for BODS and NH3 have been deleted based on review of data, showing no impact on
water quality in the Catawba River.
If any parts, measurement frequencies or sampling requirements contained in this permit 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 in the form of a written petition, conforming to Chapter 150B of the North Carolina General
Statutes, and filed with the office of Administrative Hearings, 6714 Mail Service Center, Raleigh, North Carolina 27699-
6714. Unless such a demand is made, this permit shall be final and binding.
This permit is not transferable. The Division may require modification or revocation and reissuance of the permit. This
permit does not affect the legal requirements to obtain other permits which may be required by the Division of Water
Quality or permits required by the Division of Land Resources, Coastal Area Management Act, or any other Federal or
Local governmental permits may be required. If you have any questions or need additional information, please contact
Ms. Jacquelyn Nowell at telephone number [phone], extension 512.
Sincerely,
Avai

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 parameter(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 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 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.
10

Permit NC0004375
Test data shall be complete, accurate, include all supporting chemicaVphysical 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)= ETPma =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.
11

ti
Permit NC0004375
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— 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)

NC0004375 — Clariant Corporation Factsheet Amendment 11/20/02
Upon additional review by the NPDES Unit, the following items have been addressed
and modified in the final Clariant permit.
1. The sentence: "The Division will need to assess the necessity for the entire 3.9 MGD
flow requirement upon the next renewal of the Clariant permit on June 30, 2005. "
will be added to the text of the permit cover letter.
2. The new DWQ DMR form for sampling PPA data will be attached to the cover letter.
The sentence at the bottom of the PPA condition Section A.(6.) has been modified to
say that "two copies of the report will be sent to DWQ Central Files...." This
replaces having the PPA form sent to the NPDES Unit and the Compliance
Enforcement Unit. Central Files retains all permit effluent data, therefore
information should be sent directly there.
3. The nutrient worksheet will also be attached to the letter instead of being included as
a page in the permit.
4. An email was sent to Bob Sledge and Shannon Langley in the Compliance Unit
addressing the issue of their notification about the addition of the new wastestream.
He indicated that the Unit had no problem with the condition being included in the
permit. Updating the Tier 2 effluent limitations in the information database will be
addressed upon receipt.

11/20/2002
Notes to Clariant File:
1. The special staging requirement for discharge. A research of the Clariant file found a
12/5/96 memo from the DWQ Instream Assessment Unit (IAU) addressing Clariant's
1998 challenge of several conditions found in the permit. IAU concurred that the staging
requirement was not consistent with the BOD5 and NH3 effluent limits in the permit, and
that because of the lower BOD5 limit there should be a modification. The response
memo states that "The case scenario where the river flow is greater than 175 cfs and less
than 250 cfs is no longer necessary because the combination of the revised BOD5 and
NH3 limits would be much lower than the allowable 1044 lb/day. Since the new
guidelines or limits are low, the equation is only needed when the river flow is less than
or equal to 175 cfs." The only scenario needed is as follows:
River flow < 175 cfs, BOD5 + 0.54 NH3 < 566.41b/day
Explanation for BOD5 + 0.54 NH3 < 566.41b/day
Permitted BOD5 limits, Tier 1 - 329.0 #/d (mo. avg.) 810 #/d (da. max.);
Tier 2 - 485.0 #/d (mo. avg.) 1215 #/d (da. max.)
Permitted NH3 limits, Tier 1 & 2 - 618 #/d (mo. avg.) 927 #/d (da. max.)
Using monthly averages
1) 329 + 0.54 (618) = 329 + 333.72 = 662.72 is not < 566.4
2) 485 + 0.54 (618) = 485 + 333.72 = 818.72 is not <566.4
Using daily maximums
1) 810 + 0.54 (927) = 810 + 500.58 = 1310.58 is not < 1044 #/d
2) 1215 + 0.54 (927) = 1215 + 500.58 = 1715.58 is not < 1044 #/d
DAG would like to remove this requirement. However, further research needs to be
done on the staging requirement, its history and whether it should remain a part of
the permit. This should be reviewed more thoroughly upon next permit renewal.

Hello Marshall, thanks for your comments.
The typographical errors that you submitted will be corrected.:
a. In Section A(1)a, in footnote 5, "Section A(5)" should be Section A(6).
( Your note said footnote 4 but I think the staging requirement is footnote
5) .
b. In Section A(1)b, in the Effluent Characteristics column for BOD, the
footnote will be corrected to 5.
c. In Section A(1)b, in footnote 5, "Section A(5)" should be Section A(6).
see (a) .
d. Regarding the DO monitoring requirement. This is a renewal of the
existing monitoring requirement for DO for the last permit issued in 1996.
The 1991 factsheet indicated that a DO limit with a minimum of 5 mg/1 was a
part of the permit, but the 1991 permit issued did not have DO limited.
With the current renewal, a review of instream DO data for the past three
years showed no violations of the 5 mg/1 DO standard downstream of the
Clariant facility. It would not appear that an effluent DO limit is
necessary.
e. You are correct that Hg should be sampled as a grab instead of
composite. A letter to the facility about the new method 1631 will clarify
this and it will be corrected in the final permit.
f. According to 15A NCAC 2B. 0505(c)(3)(C), chlorides is not one of the
parameters listed that should be grab sample. It is not a volatile and
should be sampled as composite.
g. Clariant has agreed to the addition of a condition/permit language that
they will notify DWQ at least 14 days prior to the addition of any new waste
source to the treatment facility.
Please contact me if there are any additional comments or questions. Thank
you.

Clariant operates a specialty chemical and dye manufacturing facility in Mount Holly, North
Carolina (Clariant-Mt. Holly East Plant) in the Northwest portion of Mecklenburg County.
Wastewater from the facility is treated in an on -site wastewater treatment plant (WWTP) and
discharged to the Catawba River under NPDES Permit No. NC0004375. The permit allows a
discharge of up to 3.9 MGD of treated industrial wastewater through one outfall (001). Clariant
has submitted an application for renewal of this NPDES permit. The NPDES Unit has reviewed
the application, correspondence files, discharge monitoring reports, permit files, instream data
and other pertinent data in developing this permit. This fact sheet summarizes the rationale
used to determine permit limits and conditions.
Wastewater from the Clariant Corporation facility is treated in the on -site WWTP. The
treatment plant is comprised of the following treatment units:
• Two separate sewer systems, acid sewer and alkaline sewer.
• Acid sewer lift station pumps.
• Alkaline sewer lift station pumps.
• 2.5 MG lined equalization basins for non -alkaline wastewater.
• 3.5 MG lined equalization basins for alkaline sewer wastewater.
• Two pH neutralization tanks with lime slurry addition.
• Two primary clarifiers.
• One 4.5 MG equalization basin with mixers and aerators.
• One 2.5 MG activated sludge aeration basin with jet mixing and aerators.
• Two secondary clarifiers.
Fact Sheet
NPDES Renewal
Page 1

c
• Two sludge holding tanks for primary and secondary sludge.
• Two belt filter presses.
• Effluent polishing canal that flows to a small final exit pond that has an aerator in it
to provide positive dissolved oxygen prior to release into the Catawba River.
• Staged discharge facility that includes an effluent lift station can deliver the entire
effluent flow of the WWTP to a lined 360 MG effluent holding basin for storage and
pretreatment.
The last wasteload allocation was conducted in 1991. Since that time, there have been changes
that would dictate a reevaluation of the wasteload allocation.
The facility's existing permit incorporates water quality based limits for ammonia,
acenaphthene,
acenaphthylene, anthracene, benzo(a)anthracene, 3,4-benzofluoranthene,
benzo(k)fluoranthene, benzo(a)pyrene, chrysene, fluorene, naphthalene, phenanthrene and
pyrene. Monitoring is also performed on various other parameters including dissolved oxygen,
fecal coliform, total nitrogen, total phosphorus, total phenols, total sulfate, chemical oxygen
demand, methylene blue active substances, iron, chlorides and mercury. The existing permit
also includes limits for a variety of organic chemicals as required by the US EPA for OCPSF
categorical dischargers. These chemicals are: acrylonitrile, benzene, bis(2-ethylhexyl)phthalate,
carbon tetrachloride, chlorobenzene, chloroethane, chloroform, 2-chlorophenol, di-n-butyl
phthalate, 1,2-dichlorobenzene, 1,3-dichlorobenzene, 1,4-dichlorobenzene, 1,1-dichloroethane,
1,2-dichloroethane, 1,1-dichloroethylene, 1,2-trans-dichloroethylene, 2,4-dichlorophenol, 1,2-
dichloropropane, 1,3-dichloropropylene, diethyl phthalate, 2,4-dimethylphenol, dimethyl
phthalate, 4,6-dinitro-o-cresol, 2,4-dinitrophenol, 2,4-dinitrotoluene, 2,6-dinitrotoluene,
ethylbenzene, fluoranthene, hexachlorobenzene, hexachlorobutadiene, hexachloroethane,
methyl Chloride, methylene chloride, nitrobenzene, 2-nitrophenol, 4-nitrophenol, phenol,
tetrachloroethylene, toluene, total cyanide, 1,2,4-trichlorobenzene, 1,1,1-trichloroethane, 1,1,2-
trichloroethane, trichloroethylene, vinyl chloride.
Facility Description
Clariant operates one remaining textile chemical and dyestuff plant within the complex. This
plant will be shut down prior to January 1, 2003. Other OCPSF activities are continuing.
Clariant has no plans to modify any of the on -site WWTP processes or components. Although
changes are planned for the site manufacturing and warehousing operations, the wastewater to
be produced is compatible with existing WWTP design. Clariant is converting the underutilized
portions of the Clariant-Mt. Holly East facility into an industrial park, as space becomes
available. Wastewater present or planned for immediate inclusion are from the following
industrial categories of the US EPA Effluent Guidelines and Standards:
• Organic Chemicals, Plastics and Synthetic Fibers (OCPSF) (40 CFR Part 414);
• Centralized Waste Treatment (CWT) Point Source (40 CFR Part 437); and
• Non -categorical industrial wastewaters.
Discharge Monitoring Report Data Review
According to the self -monitoring data, the facility is achieving compliance with the current
permit limits.
Current Stream Conditions
The Catawba River flows from western North Carolina into Lake Wylie. The Catawba River is in
the Catawba River drainage area. The Catawba River is classified as a class WS-IV CA water in
the Catawba River Basin (North Carolina's classification system), which means it is a protected
water supply and is designated for drinking water.
The Catawba River is not listed as an impaired water according to North Carolina's draft 2000
303(d) list.
Fact Sheet
NPDES Renewal

G
Instream Monitoring
Clariant conducts monitoring of the Catawba River, both upstream and downstream of the
WWTP discharge. Analysis of approximately 3 years of instream data (1989 - 2002), shows no
violations of North Carolina's dissolved oxygen standard.
Fact Sheet
NPDES Renewal
Page 3

Compliance Summary
Staff Reports indicate that the facility is well maintained and operated. The Clariant
Corporation WWTP has a very good compliance record. Over the past three years, the facility
had no violations of monthly average limits.
Toxicity Testing
Current Requirement: Chronic toxicity limit monitored quarterly @ 1.8%.
The facility has a good toxicity compliance record over the past six years.
Recommended Requirement: Chronic toxicity limit monitored quarterly @ 1.8%.
Toxicant Analysis
Using the self monitoring data required per the NPDES permit and the approved Long Term
Monitoring Plan, reasonable potential analysis' were conducted on the following toxicants:
iron, manganese, chloride, mercury, total phenols and total sulfate. The standards used for the
analysis are consistent with the standards for a class WS-IV stream.
Refer to the proposed changes section to see results.

Proposed Changes
Since Clariant is developing the facility as an industrial park for compatible industrial
operations, 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. Most of the NPDES permit limits for the facility have
been significantly reduced compared to current limits due to the planned changes at the
Clariant facility.
The daily maximum limits and monthly maximum limits for the following parameters have been
significantly reduced: 5-day biochemical oxygen demand (43% reduction), total suspended
solids (44% reduction), ammonia -nitrogen (5% reduction) and fifty-three (53) OCPSF
parameters (59 to 81% reduction).
The monitoring frequency for total iron, MBAS, manganese, sulfates and chlorides have been
reduced from monthly to quarterly based on results of the reasonable potential analysis that
indicated that no violation of the water quality standard should occur from the discharge..
Daily maximum limits and monthly average limits for twenty-five (25) CWT parameters have
been added. These include limits for the following: total antimony, total arsenic, total barium,
total cadmium, total chromium, total cobalt, total copper, total lead, total mercury, total
molybdenum, total nickel, total selenium, total silver, total tin, total titanium, total vanadium,
total zinc, acetone, acetophenone, aniline, bis(2-ethylhexyl)phthalate, 2-butanone, butylbenzyl
phthalate, carbazole, o-cresol, p-cresol, n-decane, 2,3-dschloroaniline, fluoranthene, n-
octadecane, phenol, pyridine and 2,4,6-trichlorophenol.
The monitoring frequency for OCPSF parameters has been reduced from quarterly to annually.
However, should any annual monitoring result in detection of an OCPSF parameter, then
quarterly monitoring must be performed until four consecutive quarterly samples result in non -
detection.
Monthly monitoring for chromium and zinc have been added to the permit based on new
wastewater streams from Seaboard Container Cleaning and SCR -Tech that indicate their
presence.
Annual average effluent limitations for total nitrogen and total phosphorus have added to the
permit based on the Catawba River Basin Management Plan for nutrient protection in the Lake
Wylie watershed. These are interim limits based on current information from the facility.
A special condition has been added to the permit that will require that Clariant will conduct a
BAT study for the development of more accurate nutrient limits in 2003.
Mercury continues to be a water quality concern throughout North Carolina. Holders of NPDES
permits have worked with the state to reduce potential risks from this pollutant, including
tasks associated with collecting and reporting more accurate data. The most commonly used
laboratory analysis (EPA Method 245.1) has a detection limit of 0.2 ug/L while the current
water quality standard is an order of magnitude lower at 0.012 ug/L. A more recently
approved analytical test (EPA Method 1631) should produce a detection limit below the level of
the standard. This will allow the Division to assess potential water quality impacts from
discharges more accurately. Therefore, beginning on or before September 1, 2003, you will be
reciuired to begin using EPA Method 1631 when analyzing for mercury.
Instream monitoring for GODS and NH3 have been deleted based on review of data, showing no
impact on water quality in the Catawba River.

Jackie,
As we briefly discussed, I don't have any problem with the way this has
been written. I just hope they will give us the update when they go
ahead with the changes. In the wonderful world of BIMS, I don't know
who will actually have the responsibility or authority to make the
changes after we get their notification.
Thank you,

SUMMARY OF CMUD/DWQ/SCDHEC
SETTLEMENT AGREEMENT
INTRODUCTION
In the summer of 2001, the South Carolina Department of Health and Environmental
Control (SCDHEC) filed a Petition for a Contested Case in the North Carolina Office of
Administrative Hearings regarding the renewal of NPDES Permit No. NC0024970, the Charlotte
Mecklenburg Utilities Department (CMUD) McAlpine Creek Wastewater Treatment Plant. The
primary complaint on the part of SCDHEC has been that the permit was renewed without a
phosphorus limit. Nearly all of South Carolina's municipal dischargers to the mainstem Catawba
(upstream of Lake Wateree) have been given phosphorus limits, generally equivalent to 1 mg/L.
The McAlpine Creek WWTP permit had a phosphorus optimization study special condition that
stipulated preparatory requirements for the facility to ready itself for the upcoming phosphorus
Total Maximum Daily Load (TMD).
Since the summer, SCDHEC, the North Carolina Division of Water Quality (NCDWQ)
and CMUD have been working towards achieving consensus on an appropriate phosphorus limit
for the McAlpine Creek WWTP. The understanding has been that this decision will also affect
DWQ's permitting strategy for three additional municipal permits: CMUD - Irwin Creek WWTP,
CMUD - Sugar Creek WWTP, and Union County - 12-Mile Creek WWTP.
The final settlement agreement includes the terms of the limits for all three CMUD
plants. A similar strategy will be used by DWQ to limit phosphorus in the Union County permit.
SUMMARY OF SETTLEMENT AGREEMENT
Limits at McAlpine Creek WWTP
Based upon a construction schedule provided by CMUD during the settlement
proceedings, the compliance date for the total phosphorus limit at the McAlpine Creek WWTP is
set for February 28, 2006. At this time, the McAlpine Creek WWTP must meet a 534 lbs./day
total phosphorus limit. This limit is to be calculated as a 12-month rolling average. It
corresponds to a 1 mg/L limit at McAlpine Creek's permitted flow of 64 MGD.
This limit, as well as the monthly mass cap described below, shall be incorporated into a
major modification to NPDES Permit NC0024970 with special condition language to be included
with reference to the Irwin and Sugar Creek WWTPs. Since SCDHEC's stipulation was that any
limit come into effect prior to the expiration date of the permit, the permit expiration date will
also be modified to February 28t, 2006 (instead of June 30, 2005). This puts the permit out of
sync with the Basinwide schedule, but is within the five years allowable for a permit term under
federal regulations.
Bubble Limit
A major point of the settlement agreement is the idea of a bubble limit. This refers to a
mass limit for total phosphorus that applies to discharge at the three CMUD plants combined.
This type of a limit would give CMUD more operational flexibility with regard to phosphorus
removal.
The bubble limit, to be calculated as a 12-month rolling average, is 826 lbs./day of total
phosphorus from all three CMUD plants. This corresponds to a 1 mg/L phosphorus limit at
permitted discharge for the three plants. If CMUD conducts construction activities at either the
Sugar or Irwin Creek plants, the compliance date for this bubble limit will be February 28, 2007.

If CMUD decides not to conduct construction activities at either plant in order to achieve
compliance, the bubble limit will come into effect on February 28, 2006. This is identical to the
compliance date at the McAlpine Creek plant.
Special condition language will be included in the Irwin and Sugar Creek WWTP permits
regarding the compliance date.
Mass cap
In order to be protective of the water quality at the downstream lakes in South Carolina,
SCHEC requested that monthly mass caps also be included as part of the total phosphorus limits
at the three CMUD plants. This would also ensure optimized operation of the plants at all times.
The mass caps at the three plants take the form of a monthly average mass limit and
correspond to a concentration limit of 2 mg/L at maximum permitted flow. At McAlpine Creek,
this limit is 1,0671bs. /day of total phosphorus beginning February 29, 2006. At the Sugar and
Irwin Creek plants, the mass caps only come into effect if construction activities are pursued at
each plant. At Sugar Creek WWTP, the limit is 334 lbs./day with compliance commencing on
February 28, 2007. At Irwin Creek WWTP, the limit is 250 lbs./day with compliance
commencing on February 28, 2007.
TMDL
As part of the settlement agreement DWQ requested a provision for full inclusion in the
TMDL process for both DWQ and all affected NC entities (to be provided in a list by DWQ).
APPLICABILITY TO PERMITTING PROCESS
The three CMUD permits will have the bubble limit included as a special condition.
Monitoring for phosphorus will be included in the regular effluent limit pages. Mass caps will
also be included in the effluent limit pages, with a footnote specifying applicability (for Sugar and
Irwin Creek plants) and compliance dates.
The Union County - 12 Mile Creek WWTP shall have a mass limit equivalent to 1 mg/L
at the permitted flow. As with the three CMUD plants, compliance for this limit is to be judged
as a rolling annual average. Special monitoring language is being developed for this situation. It
is also recommended that the phosphorus optimization study special condition from the original
McAlpine Creek WWTP permit be included in this permit to allow DWQ time to review the
County's preparations for the impending phosphorus TMDL.

Re: NPDES Permit Number NC0004375; Trial Period Data for Treatment of Solicited
3rd Party Industrial Wastewater Customers
Dear Ms. Nowell;
This letter and enclosed data tables contain information from the treatment of 3rd party
wastewater at the Mt. Holly East Site. My February 12, 2001 letter to Mr. David Goodrich,
promised a quarterly report on operating and shipment data. I have been sending the reports to
both Mr. Goodrich and Mr. Michael Myers.
This letter and attached data tables contains all 2002 information through July. I am
sending you the entire report to date rather than just the second quarter data.
The 3rd party wastewater treatment trials continue to proceed smoothly and the
wastewater treatment plant continues to perform well.
I appreciate the Division's helpful assistance provided during the trial period.
Sincerely;
P76,xicp6aen
Gary P. Sanderson, P.E.
Plant Services Manager

To: "NCDENR - Mike Myers" <[e-mail]>,

CC: "Ned Fiss" <[e-mail]>,
"Clariant - Gary S." <[e-mail]>
Michael and Jackie,
File 13020s009.xls is 18-months of Clariant data for the RP Analysis: Manganese, Iron,
Chlorides, Mercury, Total Sulfate, Total Phenolics. I completed the RP Analysis spreadsheet
as much as possible using this data. Please note/review the following:
1. Manganese, Mercury, Total Phenolics are entered into the RP analysis worksheet as ug/L.
Please make sure this is correct.
2. Iron and Chlorides are entered into the RP analysis worksheet as mg/L. Please make sure
this is correct.
3. Total Phenolics was entered into the worksheet labeled "Phenol" (on the RP Analysis). I'm
not sure if this is correct, but there was no worksheet set up for "Total Phenolics".
4. I did not add the Total Sulfate data to the RP Analysis b/c there was no worksheet set up
for it.
I believe that I have given you enough information/data to complete your evaluation of the RP
Analysis. Please let me know if you have any questions or if there is additional information
that is needed.
Thanks. Lili

The Clariant Corporation operates an integrated organic chemicals manufacturing facility
on the Catawba River at Mount Holly, North Carolina. The site includes a batch organic
chemical production facility which currently produces dyes for use in the textile industry
a herbicide active ingredient and specialty chemials. The site also receives"3rd party
wastewater from off -site OCPSF, textiles and soap and detergent manufacturers. The on -sit
manufacturing of dyes will cease in December 2002. New wastewaters from on -site
operations for regeneration of air pollution control catalysts and transporation equipment
cleaning will be generated beginning in late 2002. All site wastewater is treated in an
activated sludge wastewater treatment plant (WWTP) and discharged to the Catawba River.
Additional information on future wastewater sources is attached.
