Special Instructions or Conditions
Staging Requirements: Applicable April 1-October 31. Permittee will calculate a
running daily average stream flow as determined by turbine operations at Mt. Island
Dam, leakage at the dam (80 cfs) and 7Q10 flow (15 cfs) of Dutchman's Creek.
Effluent release is to be controlled such that projected release of BOD and NH3 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 < 175 cfs: BODS + 0.54 (NH3-N)
. 566.4 lb/day
(2) When the daily river flow is calculated to be > 175 cfs but < 250 cfs: BODS + 0.54
(NH3-N) s. 1044 lb/day
These staging requirements are to avoid dosing during minimum release periods.

(Formerly known as Sandoz Chemicals Corporation). Industry requesting renewal of
existing NPDES permit. The 3.9 MGD facility manufactures and processes dyes and
organic chemical and manufactures an agricultural herbicide known as Norflurazon.
Clariant indicates that the herbicide is prevented from entering the process wastewater
through management and operational practices. Washwaters are collected and used in new
batch makeup. Dry collections are used. Low vapor pressure and solubility of the
herbicide prevent assimilation into wastewater.
Chlorinated organic compounds have not been detected in the effluent since the upgrading
of the aeration basin has been completed.
A very involved WLA was done in 1990 by R. Swanek, Clariant had many questions and
modification requests to the draft permit.

Staging Requirements- Submitted by Clariant in Jan. 1990 letter to DEM.
Applicable April 1-October 31 Permittee will calculate a running daily average stream flow
as determined by turbine operations at Mt. Island Dam, leakage at the dam (80 cfs) and
7Q10 flow (15 cfs) of Dutchman's Creek. Effluent release is to be controlled such that
projected release of BOD and NH3 using the most recent analytical values for these
parameters will not exceed the value given in the following formulas:

CLARIANT CORP.- MT. HOLLY PLANT JMN
page 2
(1) When the daily river flow is calculated to be < or = 175 cfs: BOD5 + 0.54 (NH3-N) <=
566.4 lb./day
(2) When the daily river flow is calculated to be > 175 cfs but < or = 250 cfs: BOD5 + 0.54
(NH3-N) <= 1044 lb./day
These staging requirements are to avoid dosing during minimum release
periods.
Revision to Phenols Limit in 7/93: Early in 1993, Sandoz obtained an estimate of
the 30Q2 flow of 716 cfs from USGS and requested that this flow be used to recalculate
their phenol limit, instead of the minimum daily average flow of 329 cfs that had been used
in the ' 89 - '90 WLA process. Limit revised from monthly avg. of 1.8 lbs/day and daily
max. of 3.6 lbs/day to a new monthly avg. limit of 3.9 lbs/day since it was determined
that " the modification should not detrimental effects on water quality. ...Taste and odor
problems at water supply intakes are caused by chlorinated phenols, and many of these are
limited through the OCPSF guidelines " .
Permit Adjudication of Mercury Limit in 8/91 - Plant adjudicated permit because
mercury limit of 0.022 µg/1(weekly avg.) and 2.4 nil (daily max) given and facility
indicated that no mercury was used in any processes noris Hg present in their caustic soda.
Thought that the value that limit was based on was a random instrument variation because
the values before it and after it were below detection. In Sept. 1991, we recommended that
the mercury limit be dropped and mercury monitoring be continued to the lowest detection
level (0.2 µg/1).
Clariant's modification requests in current renewal,application February
1996
- Propose dropping monitoring for mercury, iron, manganese, MBAS, and
dropping the quarterly monitoring for the five specific phenols
Review:
Mercury- Tox analysis shows of 27 values, all are below detection except for 1
value @ 1 14/1, recommend mercury limit be dropped. Continue with
quarterly monitoring.
Iron - max. predicted value, less than 1/10 of allowable recommend iron monitoring
be dropped.
Manganese - max. predicted value > than allowable based on one value of 9.1 mg/1, next
highest values would be 1.4 mg/1 and 0.79 mg/l. Remove that 1 outlier value, then max.
predicted value > than 1/10 of the allowable and monitoring would be still be
recommended. Since the 9.1 mg/1 value seems to be real (also reported by facility in data
sent in with application), will not recommend Mn limit but continued
monitoring.
MBAS - max. predicted value > than 1/10 of allowable. however none of the actual
values > than 1/10 of allowable. Recommend Quarterly monitoring or dropping it
all together.
Five specific phenols - all values BDL except for 1 in 4 years of sampling,
recommend quarterly monitoring be dropped.

NH3 limit given as BPJ limit in 1990 after DEM met with the facility. The permit was
modified for a new flow limit of 3.9 MGD rather than 2.25 MGD. This flow was used to
develop a BPJ limit for NH3 assuming a concentration of 20 mg/l. The resulting monthly
average limit was 6511b/day. A factor of 1.5 was used to develop the daily max. limit of
9771b/day. (March 1990 memo to Sandoz file from R. Swank)
The NH3 limit was not changed with the updated guidelines in this WLA.

Facility Name _Clariant Corp. Permit # _NC0004375 Pipe #001
CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic Bioassay
Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or significant mortality
is _1.8 % (defined as treatment two in the North Carolina procedure document). The permit holder shall
perform guarterry monitoring using this procedure to establish compliance with the permit condition. The first
test will be performed after thirty days from the effective date of this permit during the months of
_MAR JUN SEP DEC .. Effluent sampling for this testing shall be performed at the NPDES
permitted final effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B.
Additionally, DEM Form AT-1 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in
association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent toxicity
sample must be measured and reported if chlorine is employed for disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly monitoring will
begin immediately until such time that a single test is passed. Upon passing, this monthly test requirement will
revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of
Environmental Management 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 and appropriate environmental controls, shall constitute an invalid test and will require immediate
retesting(within 30 days of initial monitoring event). Failure to submit suitable test results will constitute
noncompliance with monitoring requirements.

Re: Additional lnformation
NPDES Permit NC0004375
Mount Holly Plant
Mecklenburg County
Dear Mr. Nizich:
Your letter of May 9, 1996 included four additional information needs. Each are addressed
below. If you need information beyond what is provided, please let me know. I will be happy to
assemble it.
Outfall 001 average flow:
I have reviewed our monthly submittals of data for the years of 1991-1995. You are
correct. The Mt. Holly Plant average treated wastewater flow for the four year period has
been 1.41 MGD. Our water flow schematic was in error. Enclosed is an updated
schematic. You will notice changes in OCPSF contribution as well. The mistakes were
caused by using flow information from a source other than our outfall flume.
Stormwater:
Later this week I will forward a copy of the plant's stormwater drawing together with
calculations showing how the 225,000 gpd contribution to our wastewater treatment plant
influent was derived.
Groundwater remediation:
The Mt. Holly Plant has a RCRA wellpoint system that serves as a "curtain wall"
between our wastewater treatment plant and the Catawba River. This system currently
extracts 100,000 gpd of groundwater and discharges it to the wastewater treatement plant.
We will be able to gather composite samples of this material for the BOD5 data you
requested in your letter. With your approval, I will send the data to you in a package in
late June.
There are 15 CERCLA recovery wells that discharge individually into the plant sewers.
TN)
sv

The pumps in each of these wells cycle on and off based on water level in the well
casings. We do not have any way of gathering composite samples from any of these
wells. Getting set up to do this would take both significant time and money. I propose
deleting this requirement.
If it would help, we can send you a copy of the latest semi-annual "effectiveness of
corrective action report" that we prepare for the Solid Wast Management Division.
While the report does not present BOD5 data, it does give specific organic chemical
analytical data. If this information would be of any benefit, please let me know.
Average influent and effluent BOD5 data for the latest twelve month period:
Enclosed is data from May 1995 through April 1996. If you need any additional
information, I will be happy to provide it.
Per our telephone conversation yesterday, we will be pleased to have you visit our facility on
June 13, 1996. I have enclosed a process flow diagram of the wastewater treatment plant to help
familiarize you with our facility prior to your visit.
Sincerely,
Gary P. Sanderson, P.E.

Discharges are to be released in accordance with the following:
Staging Reouiremer,ts
If at lease one turbine at Mt. Island Dam is operating at the baginnirg of each discharge day, BOD5 and NH3-N can be
released in accordance with Equation No. 1 until 7:00 p.m. If no turbines are in operation at 7:00 a.m., BODS and N113-N
can be released in accordance with Equation No. 2, as defined below,,until turbine operation begins. When at least one
turbine at Mt. Island Dam begins operating, BOD5 and NH3-N ca'i be released in accordance with Equation No. 1 until 7:00
p.a. If at lease one turbine begins operation after 7:00 p.m., BOD5 and NH3-N can be released in accordance with
Equation 1. At 7:00 p.m. the total daily stream flcw during the 7:00 p.m. period will be determined as follows: A
24-hour average discharge rate will be calculated which will include the minimum instaneousJOm quantityf.low7l plus the 24-hourCPS
7Q10 from Dutchman Creek (i.e., if 30 x EE6/3600 Et3 was released by one turbine from p.m.,
average would'be [30 x EE6/3600 x 24 + 80 + 15j = 442). If the 24-hour average flow rate is greater than or equal to 329
CFS, B0D5 and NH3-N can be discharged from 7:00 p.m. to 7:00 a.m. in accordancewith Equation No. 1.. If the 24-hour
average flow rate i= less. than 329 CFS, BODS and NH3-•N' can be discharged from 7:00 p.m. to 7:00 a.m. in accordance with
Equation NO. 2. if at lease one turbine begins operation after 7:00 p.m., BOD5 and NH3-N can be released in accordance
with Equation 1.
EQUATION NO. 1 Summer. (1) Winter (2)
BODS 1 0.45 (NH3-N) < 111.1 lbs/hr. avg. BOD5 + 0.5 (NH3-N)< 197.9 lbs/hr. avg.

Note for Jackie Nowell
From: Jackie Nowell

Subject: Clariant Instream Monitoring
To: Greg Nizich
I have reviewed the instream data for the subject facility and recommend continuation of
instream monitoring for most of the existing parameters: temperature, pH, BOD5, DO, and
conductivity. Based on the data reported for NH3, all values upstream and downstream
below detection for the past three years , I would recommend deletion of the instream
monitoring for NH3.
Also, I noticed that in March 1995, Clariant started reporting their instream BOD5 in lbs/day
instead of mg/1. There are now some really large numbers for instream BOD5 (in lbs) being
reported but in order to calculate mg/1, you have to convert riverflow info to MGD, etc. etc.
My question is, did the Division request that they report BOD5 in lbs and can it be reversed
back to mg/1, so that we can more easily see the loading instream. I have placed a call to the
ORC for a further explanation. This change would be the only other one I would suggest.

SUBJECT:
Draft National Pollutant Discharge
Elimination System Permit
Clariant Corporation
Mt. Holly Plant
Permit No. 5NC0004375
Mecklenburg County
Reference is made to the above mentioned Draft National
Pollutant Discharge Elimination System Permit. We have reviewed
this permit application and determined that the proposed discharge
will not be sufficiently close to any existing or known proposed
public water supply intake so as to create an adverse effect on
water quality.
We concur with the issuance of this permit provided the
facility is operated and maintained properly, the stated effluent
limits are met prior to discharge and the discharge does not
contravene the designated water quality standards.
If we can be of further assistance, please contact us.

RE: Public Notice of Intent to Issue NPDES Permit No. NC00043 75
Clariant Corporation, Mt. Holly Plant
Dear Mr. Howard:
�n
771
We are writing on behalf of our client, Clariant Corporation, to confirm our understanding
of the applicable comment period on the above -captioned draft permit.
On October 1, 1996, Clariant received both a Public Notice dated September 6, `196=
(Attachment A) and a letter from David A. Goodrich dated September 26, 1996 (Attachment B).
The Public Notice established a comment deadline on the draft permit of October 11, 1996. The
Goodrich letter requested Clariant's comments on the draft permit within 30 days of receipt (i,e.,
by October 31, 1996). We understand that the purpose of the two letters was to accept public
comments until October 11, 1996, and to accept comments from Clariant until October 31, 1996.
Both sets of comments will be considered by the Division and will be part of the record regarding
this permit.
Clariant is in the process of preparing detailed comments and will provide these comments
to the Division by the October 31, 1996, deadline. However, we would appreciate the Division's
written acknowledgement that all Clariant comments submitted by October 31, 1996, will be part
of the application file and will be considered by the Director prior to taking final action on the
application.
Yours truly,

Comments on Permit Renewal
NPDES Permit No. NC0004375
Mecklenburg County
The Mecklenburg County Department of Environmental Protection
(MCDEP) would like to offer our comments and recommendations
concerning the NPDES Permit renewal for the Clariant Corporation -
Mount Holly Plant WWTP. As you are aware, we are involved and work
closely with the Division through a Memorandum of Agreement to
protect water quality in Mecklenburg County.
The current NPDES permit for this facility does impose
reasonably strict effluent limitations for BOD, NH3-N, Mercury,
Phenols and various organic compounds, however, the permit does not
impose any limitations on Total Nitrogen (NO2+NO3+TKN), Total
Phosphorus or Total Sulfates. In addition, a cursory review of
recent Discharge Monitoring Reports for the facility shows effluent
discharge concentrations averaging around 30 mg/1 for Total
Nitrogen, 0.60 mg/1 for Total Phosphorus and 3400 mg/1 for Total
Sulfates.
MCDEP requests that the Division require nutrient removal at
the facility as part of the overall treatment process and that the
new NPDES permit impose strict limitations on the effluent
discharge of Total Nitrogen, Total Phosphorus and Total Sulfates.
We feel that these efforts would improve the water quality
downstream in the Catawba River.

On October 1, 1996, we received a copy of a letter dated
September 25, 1996 from DWQ to Gary Sanderson of Clariant
Corporation. The letter detailed a list of significant changes to
the existing permit which would be incorporated into the permit
renewal. We agree with these changes and recommend that the
Division also evaluate the possible water quality effects from the
Total Sulfate concentrations in the effluent. The letter also
stated that monitoring for the five specific phenols has been
dropped. This should not pose a problem as long as these specific
phenols can be detected in the Total Phenols monitoring test.
If we can be of any further assistance or provide any
additional information, please contact me at [phone].
Thank you for the opportunity to comment on this permit
renewal.

Subject: Permit Changes
NPDES Permit NC0004375
Mt. Holly Plant
Mecklenburg County
Dear Mr. Sanderson:
The following is a list of significant changes to the existing permit:
• BOD5 and TSS limits (outfall 001) - These have been reduced based on application of the
OCPSF effluent guidelines for a long-term average process flow of 0.78 MGD.
Allocations have also been given for process related stormwater and filter backwash. The
attached worksheet provides a breakdown of the various wastestreams and the allocations
for each component. These limits will take effect twelve months after the effective date of
the permit to allow the facility time to evaluate compliance capability. The previous permit
limits will be in effect until that time.
• COD limit monitoring location - Since outfall 002 is being eliminated in the proposed
permit, it is necessary to evaluate compliance with the pesticide effluent guideline based
limit at outfall 001. Since current COD values for the entire wastestream would exceed the
108#/day monthly average, sampling point "12" has been designated for compliance
evaluation. The intent being to sample prior to combining with other wastestreams. As
stated in a letter dated August 26, 1996, a COD allocation for the other wastestreams can be
developed if Clariant would prefer that compliance were evaluated for COD on the total
wastestream.
• Total phosphorus (TP) and total nitrogen (TN) - Part III, Condition H requires evaluation
of the ability to meet TP and TN limits of 1 mg/1 and 6 mg/1 (summer) respectively.
• The definition of "daily" has been removed from the effluent sheets since this term is
defined in 15A NCAC 2B .0503(5).
• Iron monitoring - This requirement has been dropped.
• Mercury monitoring - This requirement has been reduced to quarterly. If this parameter is
not detected during the next permit cycle it will be dropped from the permit.
• Manganese monitoring - Based on the levels detected, monitoring is still required, however
the frequency has been reduced to quarterly.
P.O. Box 29535, Raleigh, North Carolina 27626-0535 Telephone [phone] FAX [phone]

• MBAS - Monitoring for this parameter has been reduced to quarterly based on levels
detected.
• Five specific phenols - Monitoring for these parameters has been dropped.
• Chronic toxicity language - The policy prohibiting any test from indicating toxic effects has
been in place since 1993 for all facilities monitoring toxicity. An NOV is not necessarily
sent to the pennittee as a result of a single test failure.
• Nutrients - It has been determined by the Division through intensive water quality studies
that discharges upstream of Lake Wylie, including this discharge, need to control nutrients
through the application of the best available technology (BAT) that is economically
achievable. The pennittee shall provide the Division with a study which fully investigates
the feasability of meeting an average TP limit of 1.0 mg/land a summertime TN limit of 6
mg/l.
If you have any questions regarding these changes please call Mr. Greg Nizich at 919-733-5083,
extension 541.

Applicant's Receiving Waters
Receiving Stream: the Catawba River
Classification: WS-III
Sub -Basin: 03-08-34
See Attachment A for a map showing the discharge location (s).

Description of Wastewater Treatment Facilities
The 3.9 MGD wastewater treatment facility consists of two basins for biological waste treatment,
stormwater equalization basin for nonalkaline wastewater, stormwater equalization basins for
alkaline wastewater, gravity secondary clarifiers, acid neutralization, gravity primary clarifiers, air
stripper, sludge dewatering, effluent polishing pond, staged discharge facility including effluent
storage, and post aeration, with herbicide manufacturing wastewater discharge via the acid sewer
to the 3.9 MGD treatment plant.
Summary of Existing Wastewater Treatment Plant Operation
See Attachment B (for operating facilities).
Type of Wastewater (as reported by applicant)
2 % Domestic
98 % Industrial
2 . PROPOSED EFFLUENT LIMITATIONS
See attached copy of Effluent Page (s) from Draft Permit.
3 . MONITORING REQUIREMENTS
The applicant will be required to monitor regularly for flow and those parameters limited in
Section 2 above with sufficient frequency to ensure compliance with the permit conditions.
Frequency, methods of sampling, and report dates will be specified in the final permit.
4. EFFECTIVE DATE OF PROPOSED EFFLUENT LIMITS
(AND COMPLIANCE SCHEDULE IF APPLICABLE)
The limits become effective on the date of permit issuance.
5 . PROPOSED SPECIAL CONDITIONS WHICH WILL HAVE A
SIGNIFICANT IMPACT ON THE DISCHARGE
(1) Chronic Toxicity Limit
(2) Staging Requirement

6. BASIS FOR PROPOSED EFFLUENT LIMITS
The limits for the facility were derived from the effluent guidelines. The BOD5, COD,
TSS and pH limits were developed from the effluent guidelines contained in 40 CFR 414 Subpart
H (Dye manufacturing) and 455 Subpart A (pesticide manufacturing. State water quality standards
dictate limits for OCPSF/Pesticide priority pollutants when they are more stringent than guideline
limits.
The toxicity limit was based on the instream concentration in the receiving stream. Compliance
with the limit is determined using an EPA approved test.
Monitoring in the permit is based on the requirements of 15 NCAC 2B .0500 for Class IV waste
treatment facilities.
7. REQUESTED VARIANCES OR ALTERNATIVES TO REQUIRED STANDARDS

Note for Greg Nizich
From: Jackie Nowell
Date: Wed, Sep 4, 1996 9:35 AM
Subject: Clariant Instream Monitoring
To: Greg Nizich
NGoo 04 675
I have reviewed the instream data for the subject facility and recommend continuation of
instream monitoring for most of the existing parameters: temperature, pH, BOD5, DO, and
conductivity. Based on the data reported for NH3, all values upstream and downstream
below detection for the past three years , I would recommend deletion of the instream
monitoring for NH3.
Also, I noticed that in March 1995, Clariant started reporting their instream BODS in lbs/day
instead of mg/l. There are now some really large numbers for instream BODS (in lbs) being
reported but in order to calculate mg/1, you have to convert riverflow info to MGD, etc. etc.
My question is, did the Division request that they report BOD5 in lbs and can it be reversed
back to mg/1, so that we can more easily see the loading instream. I have placed a call to the
ORC for a further explanation. This change would be the only other one I would suggest.

I am writing to discuss the issue of an appropriate COD limit at outfall 001. As I may have mentioned
during our previous phone conversation, the proposed limit of 108 lbs/day is based on the pesticide
effluent guidelines (40 CFR 455) at a production rate of 12,000 lbs/day. No allocation is given for COD
in the OCPSF guidelines. EPA's reasoning for this as stated in the OCPSF development document is that
adequate treatment of BOD5 achieved sufficient removal of non -conventional pollutants such as COD, so
guideline limits were established for BOD5 and TSS only. Nevertheless, due to the pesticide wastestream
component, EPA guidelines require that a COD limit be imposed for outfall 001.
Before a limit can be established, an appropriate allocation for OCPSF-related COD must be determined.
Please provide COD sampling data (one analysis per week for four weeks) for either the OCPSF
composite wastestream or representative wastestream. In addition, provide monthly average influent and
effluent COD values for the latest twelve month period available for the wastewater treatment plant. If
prior monitoring data is not available we can discuss other alternatives.
Give me a call at 919-733-5083, ext. 541 if you have any questions.

All issues regarding BOD5 and TSS allocations allowed for various wastestreams have
been resolved. The attached limits calculations have been revised since they were
presented to Clariant at our June 13, 1996 meeting. The most significant changes are
with TSS due to allocations being given for non -process stormwater and filter backwash.

Ah but they have not been monitoring at the internal outfall! As my note says, 002 shows
"no data for dates requested". From what their application indicates, they don't discharge
from this outfall, so everything from 001 I assume is from the dyeing process rather than the
pesticide manufacturing area. Hence my need to look at the Dev. doc.

If they been monitoring COD at both the internal and final outfall, can we not give them the
allocation of 108 plus something for the OCPSF functions at the true outfall (basing this on
the worse case daily max they have reported)? Coleen

Just when I thought I had all the limits straight Gary Sanderson throws in a new issue. The
existing permit has a COD limit of 108 #/day at 002 (pesticide discharge) based on the eff.
guidelines for pesticides. We were going to eliminate this outfall in this renewal since it
made no sense to monitor at a point prior to treatment (002 was internal). EPA guidance
agrees with monitoring after treatment even though the OCPSF wastestream is combined
with the pesticide wastestream at 001.
Gary's concern is that COD levels at outfall 001 are consistently above the 108 #/day figure.
The DMR data shows no discharge at 002 for several years, so all the COD must be coming
from the dye manuf. area. I'll look in the OCPSF development document later to see if COD
was addressed in there.

Subject: Additional BOD Allocations
NPDES Permit NC0004375
Mount Holly Plant
Mecklenburg County
I have reviewed the information contained in your letter of June 24, 1996 and have the following
comments:
• Steam Generation - Please verify that the 0.0686 MGD of condensate is not presently included in the
0.770 MGD from the OCPSF process area shown on the flow schematic even though it is reused in
OCPSF processes.
• Filter Backwash - The Division has never given BOD allocations for this type of wastestream. The
Division has established concentration limits for TSS at 30 mg/1 monthly and 45 mg/1 daily. A
corresponding mass allocation based on these figures will be added for TSS at outfall 001.
• Stormwater - The stormwater application submitted in 1992 has been reviewed in order to characterize
BOD and TSS levels from non -production areas. For stormwater runoff areas similar to those flowing
to the WWTP, the highest BOD5 value is 6.1 mg/1(OF-6). Based on the lowest removal rate of
82.9% at the WWTP during the past 12 months, a monthly BOD5 allocation of 1.0 mg/1, and daily
maximum of 1.5 mg/1, will be given for the 0.138 MGD non -production stormwater flow. Allocations
for TSS of 30 mg/1 monthly and 45 mg/1 daily will be given for this flow as well.
• Ponding and Re -treatment Options - It was previously understood that the current flow limit of 3.9
MGD provided the flexibilty to store wastewater during winter months. No change to this flow limit is
proposed.
Once again, myself and the other staff members appreciated touring your facility on June 13, and hope the
information obtained is helpful in resolving permit issues expeditiously. Give me a call at 919-733-5083,

Dear Mr. Nizich:
•
We appreciate the plant visit you and your associates made to our site. Both Mr. Coleman and I
wish to thank you for taking the time to tour our plant and discuss issues with us on June 13th.
Below is the data requested on our RCRA groundwater pumping system at the wastewater
treatment plant.

COD BOD
No. 1 99 ppm 24 ppm
No. 2 112 ppm 39 ppm
No. 3 99 ppm 30 ppm
No. 4 110 ppm 36 ppm
After studying the information you supplied regarding proposed limits, I have a few comments
and requests that I hope you will consider as you work up limits for the plant's new permit. For
clarity, I have catagorized them as they appear on the water flow schematic.
I. Steam Generation
The site does not have a condensate return system. Approximately 70% of the water used
to generate steam, 0.0686 MGD, ends up being consumed in the production processes.
Some as wash water, some as hot water for vessel make up, and some as clean-up water
for production areas. This portion of the steam generation water really ends up in the
wastewater treatment plant as an OCPSF source.

•
NPDES Permit NC004375 June 24, 199 Letter page 2
II. Filter Backwash
The 0.087 MGD backwash from our process water intake facility contains significant
TSS. The suspended material represents solids removed from raw river water by our
river intake plant. The backwash flows through a settling canal prior to entering the
effluent canal. While we have not performed analyses to determine the exact level of
TSS contribution to our effluent, there is some. Allowance for TSS and BOD from this
source is needed.
III. Stormwater
0.087 MGD of the 0.225 MGD of stormwater flow results from runoff of rainfall on
OCPSF portions of the facility. While the other 0.138 MGD of stormwater runoff may
not have have fallen on production area locations, it is a contributor of BOD and TSS to
our wastewater treatment plant. Contribution to effluent may not be as great as OCPSF
sources, but it is not zero.
IV. Ponding and Re -treatment Operations
We usually have to store portions of our treated water from December until April,
because BOD removal is impaired by low biological activity. We re -treat and release the
stored water during the warmer months. This is normally done during June - September.
Average effluent flow rates during these months can range from 1.5 - 2.6 MGD, 6 - 85%
higher than the annual daily average. We need some latitude to allow this situation to
continue.
We look forward to working with you during the permitting period. If you need any further
information, please let me know.

Dear Mr. Nizich:
The purpose of this letter is to provide the Division of Environmental Management with --
additional information regarding the Mt. Holly Plant. A comprehensive review of our processing
operations in Building 45, the Norflurazon manufacturing plant, were begun in late spring and -?
will continue throughout the summer. The manufacturing process for Norflurazon, NOFZ,
contains several closed -loop recovery and recycle operations. These systems minimize waste,
reuse solvents, and recover product. The processing review includes sampling and testing at
various points in the production process, evaluation of the management and operational controls,
and thorough analysis of the material balance.
During the process review, we have sampled the influent to the wastewater treatment facility.
Analyses of the samples indicated that the influent contained trace levels of NOFZ in the range
of 10 to 620 ppb. We have not yet had the opportunity to sample effluent from the wastewater
facility because NOFZ manufacturing is temporarily shut down. When NOFZ processing
resumes in late August or early September, we will take additional samples of both influent and
effluent at the wastewater treatment plant.
Results of the September testing program will be forwarded to you when the work is complete.
If you have any questions, please call me.
Sincerely,
F

The areas that we have required control of (to my understanding) are those areas where
potential to contaminate existed (valving, tankage, process areas, etc.). Other general site
areas typically are not diked, nor sent to the wastewater treatment plant. We should not be
giving any allocation for "general site runoff'. Coleen

I wanted to look into the allowance alittle more after our discussion yesterday, and now that I
have I'm still not clear on implementation. The preamble to the 1987 effluent guidelines says
process wastewater includes "surface runoff from the immediate process area that has the
potential to become contaminated". This section explicitly excludes "general site surface
runoff' from process water. Is there some language in stormwater guidance documents
which says we should apply the effluent guidelines to other site runoff areas?

Dear Mr. Nizich:
In your letter of May 9, 1996, you requested a schematic of our plant's stormwater flows and
run-off area descriptions. You also asked for calculations showing the derivation of stormwater
contribution to the wastewater plant influent.
The enclosed drawing titled "Stormwater Drainage Map" is a plot plan of the Mt. Holly Plant
with stormwater areas and flow destinations indicated on it. Areas 1, 3 and 4 represent
manufacturing and warehousing portions of the complex. Areas 2 and 5 are office and laboratory
locations. That portion of Area 4 lying between the railroad tracks (on the right hand side of the
drawing) house our steam generation plant and pilot plant facilities. Stonmwater run-off from
areas 6 and 7 do not enter our wastewater treatment plant.
The calculations enclosed with this package document how we arrived at the stormwater
contribution to wastewater treatment plant flow.
I realized when putting together this package that I did not send you a process flow diagram of
our WWTP in the May 21st mailing. It is also enclosed for your review.
If there are any questions that you have when you review this material, please call me for
clarification.

Stormwater Flow to the WWTP
May 22, 1996
The calculations below are the basis for the quantity of stormwater that annunally enters and is treated
in the wastewater treatment plant. The areas of plant property conatined in the calculations are derived
from several drawings. The primary drawing used is the Stormwater Drainage Map prepared by Law
Engineering on 3/31/95. Several plot plan drawings of the WWTP were used to derive it's area .
The Mt. Holly Plant has a pumping station for stormwater that falls on Areas 2, 4 and 5. The pump
station delivers up to 175 gal/min of flow and will handle rainfall rates of less than 0.7" per day (an
inch/day of rain falling on Areas 2, 4, and 5 equates to 240 gal/min of run-off). At higher rates of
rainfall, the run-off exceeding 175 gal/min overflows to Long Creek. Also of note, an estimated 20%
of the rainwater run-off in Area 4 flows to plant sewer junction boxes rather than to the stormwater
pump station.
Assumptions:
1. Annual rainfall on the plant site is 53.73 inches per year. This information was obtained from
the Gaston County Chamber of Commerce.
2. 75% of rainfall on Areas 1 & 3 is collected in the WWTP
3. 75% of rainfall on Area 4 is collected in the WWTP
4. 79% of the rain falling in the WWTP exits via Outfall 001.
5. WWTP surface area is 1,864,000 ft2
6. 20% of rainfall on Areas 2 & 5 is collected in the WWTP

Re: Additional Information
NPDES Permit NC0004375
Mount Holly Plant
Mecklenburg County
Dear Mr. Nizich:
Your letter of May 9, 1996 included four additional information needs. Each are addressed
below. If you need information beyond what is provided, please let me know. I will be happy to
assemble it.
Outfall 001 average flow:
I have reviewed our monthly submittals of data for the years of 1991-1995. You are
correct. The Mt. Holly Plant average treated wastewater flow for the four year period has
been 1.41 MGD. Our water flow schematic was in error. Enclosed is an updated
schematic. You will notice changes in OCPSF contribution as well. The mistakes were
caused by using flow information from a source other than our outfall flume.
Stormwater:
Later this week I will forward a copy of the plant's stormwater drawing together with
calculations showing how the 225,000 gpd contribution to our wastewater treatment plant
influent was derived.
Groundwater remediation:
The Mt. Holly Plant has a RCRA wellpoint system that serves as a "curtain wall"
between our wastewater treatment plant and the Catawba River. This system currently
extracts 100,000 gpd of groundwater and discharges it to the wastewater treatement plant.
We will be able to gather composite samples of this material for the BOD5 data you
requested in your letter. With your approval, I will send the data to you in a package in
late June.
There are 15 CERCLA recovery wells that discharge individually into the plant sewers.
='r
v
73.
;v

The pumps in each of these wells cycle on and off based on water level in the well
casings. We do not have any way of gathering composite samples from any of these
wells. Getting set up to do this would take both significant time and money. I propose
deleting this requirement.
If it would help, we can send you a copy of the latest semi-annual "effectiveness of
corrective action report" that we prepare for the Solid Wast Management Division.
While the report does not present BOD5 data, it does give specific organic chemical
analytical data. If this information would be of any benefit, please let me know.
Average influent and effluent BOD5 data for the latest twelve month period:
Enclosed is data from May 1995 through April 1996. If you need any additional
information, I will be happy to provide it.
Per our telephone conversation yesterday, we will be pleased to have you visit our facility on
June 13, 1996. I have enclosed a process flow diagram of the wastewater treatment plant to help
familiarize you with our facility prior to your visit.
Sincerely,
4aiti e

No. They would have failed BODS 9 of 12 months, NH3-N 5 of 12. Not pretty. What
makes it worse is that they are in the 30 to 50% of permitted flow when making these
violations!
From: Coleen Sullins on Sun, May 12, 1996 6:19 PM

BOD 393.2 1289.8 852 2236
TSS 459.2 1834.8 976 2928
The reductions are primarily due to a much lower OCPSF process flow and disallowing the
stormwater allocation in the monthly average figures. I sent the add info letter today asking
for an explanation of the discrepancy in plant flow (compliance system vs. their schematic)
and more detailed stormwater info, so they could potentially go lower. The NH3-N load is a
big ? for me. Lula used a flow of 2.6 MGD for that calc. (at 20 mg/1) . The plant flow for
the past 5 yrs has been 1.41 MGD so 2.6 MGD seems high. They would not have met their
NH3-N Iimit several times in the last year if 1.41 was used in the calcs. I guess we need to
hold the WLA from MRO review until I get some answers to the above.

Dear Mr. Sanderson:
�EHNF
Subject: Additional Information
NPDES Permit NC0004375
Mount Holly Plant
Mecklenburg County
Preliminary review of the permit renewal application package has been completed. The following items
need to be addressed prior to preparation of a draft permit:
• Plant flow - The flow schematic provided with the application lists a flow at outfall 001 of 1.732 MGD
,for 1995, and 2.573 MGD for a more representative production year. The Division's compliance
� database lists the flow for 1995 as 1.41 MGD and the average flow for 1991- 1995 as 1.42 MGD.
o This descrepancy should be explained. If the long-term average flow of 1.41 MGD is correct, a
�\O\,,►\'� process flow value of 0.89 MGD will be used in calculating limits from the effluent guidelines. The
k' 0.89 figure is derived from the 63% OCPSF contribution shown on the schematic.
• Stormwater - A schematic of flows and runoff area descriptions (size, uses - process, non -process,
RcRA i3o,000ra etc.) should be provided for the areas comprising the 250,000 gpd figure. Calculations deriving this
fi
bmitted.
cee" yZ'W�S•�Groundwatter - Singe the groundwater remediation projects are operating, the data provided in 1989
during permit renewal should be updated. Please provide BOD5 sampling data (one analysis per week
X e,, for four weeks) for each groundwater remediation composite wastestream. In addition, provide
' monthly average influent and effluent BOD5 values for the latest twelve month period available for the
�f a� activated sludge wastewater treatment plant, as was done in 1989.
We would be interested in touring your facility to discuss these issues and gain a better understanding of
;,plant operations. Presently, June 12 or 13 are convenient dates to meet. The meeting would be more
\ productive if the information requested in the first two items above could be provided beforehand. Give
ee a • o me a call to discuss any questions or to determine an acceptable meeting date. My number is 919-733-
. •5083, ext. 541.

Re: Renewal of NPDES Permit No. NC0004375
Clariant Corporation - Mt. Holly Plant
Charlotte, North Carolina
Dear Mr. Goodrich:
Ther purpose of this letter is to request the renewal of NPDES Permit No. NC0004375 for the
Clariant Corporation - Mt. Holly Plant, provide the required information for use by the Division
of Enviornmental Management (DEM) in it's evaluation for the renewal and present additional
information pertaining to special issues Clariant wishes DEM to address in developing the permit
renewal. The current NPDES permit expires on August 31, 1996.
As outlined in your letter of January 18, 1996, the following required information is attached for
use by the DEM in it's evaluation process:
1. Three copies of the completed application form
2. The application processing fee of $300
3. Priority pollutant analysis (1995 APAM test results)
4. A narrative description of the facility sludge management plan
On January 18, 1996, Mr. Paige Straley, Corporate Environmental Manager, Clariant
Corporation, met with Mr. Greg Nizich, the permit writer for our facility. At the meeting,
Clariant provided approximately five years of monitoring data and a complete file of
correspondence relevant to the development of the current permit. During the meeting, issues
were discussed relating to potential conditions of the permit. The individual issues are briefly
summarized in this below.
1. Clariant proposes that the 3.9 MGD maximum monthly average discharge limit for
treated wastewater be retained in the new permit., Clariant needs the flexibility to
discharge treated wastewater at this rate in order to run normal manufacturing operations.
Maximum discharge rates during 1994 and 1995 do not reflect this because
manufacturing operations were depressed. The water balance sketch in this application

reflects lower flows, because it is based on 1995 data.
Manufacturing operations during 1992 and 1993 reflect more normal utilization of
manufacturing capacity. Treated wastewater discharges during these periods are also
much more reflective normal operations at the Mt. Holly Plant. Flows more indicative of
normal operations are given in parentheses on the water balance schematic.
2. We propose dropping the mercury (Hg) monitoring requirement in the new permitfThe
data we provided shows that its presence has rarely been detected, and then only at the
detection limit of the analytical method. This is not unexpected, since it is a naturally
occurring material, and we expect a low frequency of detection in upstream river water.
We use no Hg in any of our processes, and we have not used Hg-cell produced caustic
soda (NaOH) for at least the last five (5) years. There is an extensive explanation of our
position of this Hg issue in Mr. Straley's letter of May 23, 1991 and Mr. W.M. Archer's
letter of Aril 9, 1991. This correspondence may be found in the materials we provided at
the January 18, 1996 meeting. Also, your April 3, 1991 letter addressing Clariant's (then
Sandoz Chemicals Corporation) comments on the Draft permit indicated that Hg would
be re-evaluated upon request after one year of effluent monitoring and dropped based on
the data. We feel that the data suppports deletion of Hg.
3. We propose dropping the iron (Fe) monitoring requirement in the new permit. =Fe is
measured in the soluble state, and under oxidizing or neutral -pH conditions, levels of Fe
less than 2 ppm are expected since this is the approximate solubility limit of Fe. The data
provided on January 18, 1996 support this assertion. Calculation of an in -stream Fe
concentration should show no problems with WS-III water quality standards.
4. We propose dropping the manganese (Mn) monitoring requirement in the new permit.
The data provided on January 18, 1996 support this request. Calculation of in -stream
concentrations should show no problems with WS-III water quality standards.
5. We propose dropping the methylene blue active substances (MBAS) in the new permit:
The data provided on January 18, 1996 support this request. Calculation of in -stream
concentrations should show no problems with WS-III water quality standards. We also
point out that the negative environmental effect for MBAS is the surface tension effect.
In this regard MBAS is a flawed measurement because is measures only anionic
detergent species --nonionic and cationic forms are not measured.
6. We request dropping of the quarterly monitoring requirement for the five specific
phenols. We believe the data provided on January 18, 1996 show that there is no issue of
triggering water quality standard limits or OCPSF limits. In your letter of April 3, 1991
2

to Mr. Straley, item 5 makes it clear that the DEM Planning Branch requested the five
phenols for information purposes, and that a Clariant-specific application was not the
purpose of the requirement.
7. OCPSF regulations require that applicable processes involving non-complexed metal
bearing waste streams and cyanide -bearing waste streams (40 CFR 414 Appendix A) be
indicated. Clariant does not currently have synthesis processes involving any of these
waste streams, but does perform mixing/blending and repackaging operations for disperse
dyes and for organic pigments listed in this group. Current processing parallels
operations performed during the development of the curent NPDES permit.
8. The Mt. Holly Plant manufactures a herbicide, norflurazon (NOFZ), which is covered by
the Effluent Guidelines and Standards for Pesticide Chemicals (40 CFR 455). However,
NOFZ is prevented from entering the wastestream through management and operational
practices. Clariant would like to propose establishing Best Management Practices (BMP)
as a permit condition to cover the discharge from this particular operation. The practices
already in place should serve as BMP.
9. References to Outfall 002 should be deleted in the new permit.
10. The existing permit has a 3.6 pounds/day phenols monthly average limit. gThis is a
condition which was changed from the original phenols limit in the existing permit in a
letter dated September 13, 1993. We propose that limits for this parameter remain
unchanged in the new permit.
11. It is Clariant's understanding that DEM may be considering inclusion of nutrient limits in
our new permit. Clariant does not feel that sufficient information is available at this time
for determination of justifiable and reasonably attainable limits on total nitrogen. If the
new permit requires us to monitor total nitrogen and total phosphorus levels in our
discharge and make an internal technical study for nutrient limitations, such as the
example provided by Mr. Nizich for an industry on the South Fork River, we are
amenable to such a condition.
12. Clariant understands that the draft permit may place a discharge limit on chronic toxicity
such that a single failed chronic toxicity test will be grounds for a notice of violation.
Clariant objects to one failure of a chronic toxicity test being interpreted as a permit
violation and that a single failed test demonstrates chronically toxic effluent. The chronic
toxicity test is difficult to perform and depends inordinately on the skill of the technician.
It can be confounded by problems apart from the wastewater itself. Chronic toxicity
testing is meant to midel a subtle, time -dependent stream effect. A single test is a
3

"snapshot" and can only be considered as an alert to a possible chronic condition. We
believe that our argument has considerable scientific merit. Clariant suggests that the
permit be worded such that an initial chronic toxicity test failure trigger a follow-up test.
Failure of two tests in a row would then be considered a failure for permit purposes.
Clariant appreciates your consideration and cooperation in this permit renewal process. If I can
be of assistance or if additional information is needed for your review, please do not hesitate to
contact me at [phone].

Gary P. Sanderson, P.E.

ar Nrative: Acidic and alkaline wastewaters and stormwaters
are collected separately. The acidic wastewater is
neutralized and combined with alkaline wastewater for
gravity clarification. The combined wastewater is
treated in an extended aeration activated sludge system.
Sludge produced (primary and secondary) is dewatered
by belt filter and landfilled on -site. Discharge
quantity is controlled .depending on the river flow
and effluent quality by pumping excess effluent. to a 300
million gallon storage facility. Stored effluent must
• return through the activated sludge process prior to
discharge.

Item J Informabon
Section 1.9
Although actual•discharge rate of treated water is 1.5 Mi Fal/day, the
facility actually discharged 2.5 - 2.9 MX gal/day during summer in order
to recycle stored water. Had themanufacturing plant's operated at higher
rates, summer discharge rates in the 3.6 - 3.9 MM gal/dav would have
been common. Clariant requests continuation of 3.9 MM gal/day discharge
rate to allow the facility to manufacture products without constraint.
Section II.1
Maximum amount/day values represent highest overall production
for facility. During 1995, dyes and chemical production was at 67% and
Ag. Herbicide production was at 72%. Discharges to the WWTP will jncrease
with production increases.
The herbicide is prevented from entering the process
wastewater discharge through management and
operational practices. Washwaters are collected and used in new (1.6\
batch makeup. Dry collection rather than water rinses are used.
The low vapor pressure and solubility of the herbicide prevents its
assimilation into wastewater.
Section 11.15
Clariant requests that the renewed permit limts be based on the minimum
daily average river flow of 329 cfs as in the current permit.
Section II.1
No chlorinated organic priority pollutants were detected in the recent
APAM analysis (see attached results - Sept. 1995). Since upgrade of
aeration basl,n completed (December 1995), no chlorinated organic

Directions - For each parameter fisted, complete the information
requested in each ooumn in the units specified according to the instructions
given below.
Column t - Enter the daily average value of the intake water at the
point it enters the facility. If intake water if from more than one source. and
enters the fac,Oiry at separate entry points, the value Oven in column 1 should
be weighted proportional to the quantity of flow contributed from each source.
If water is treated before use, completion of this column is not required (see
instructions for column 2). Values of intake are not required for mining
activities.
• Column 2 - If all or part of intake water is treated before use,
provide values for total intake here instead on in Column 1, Also describe
briefly in item 26 'adcitional information,' the type of treatment performed on
intake water (e.g., rapid sand filtration, coagulation, flocculation, ion
that exchange,
as been etc.) and
die percent of Make water contributing to this discharge
Column 3 - Supply daily average value for the days when
discharge is actually operating or is expected to be operating (a new
discharge). Daily average values are to be computed by weighing the daily
value in proportion to the daily flow. If a discharge occurs irregularly, the
value supplied in the column marked 'Daily Average' should represent an
average for the average for the days the discharge actually occurs. Average
values are not to be supplied for pH, specific conductance, and
bacteriological parameters (e.g., cohlomm bacteria).
Cans 4 and 5 - Supply minimum and maximum value
observed (or expected for new discharge) over any one day when the
discharge is operating.
Column 6- Specify the average frequency of analysis for each
parameter as number analyses per number of days (e.g., '3 7' is equivalent
three analyses performed every 7 days). If continuous, enter 'CONT.'
When analyses am conducted on more than one indvidual grab sample
collected during the same day, the analysis frequency should reflect one
analysis whose value is the average of the individual grab sample
measurements. Average frequency should be based on an operating month.
Column 7- Specify the number of analyses performed at the
average frequency specified sn column 6, up to 365.
Column 8 - Specify sample type as follows:
G For grab sample (individual sample collected in less than 15
minutes).
trC For composite sample # is to be replaced by the average
number of hours over which the composite sample was collected.
Composite samples are combinations of individual samples
obtained at intervals over a time period, either the volume of
each individual sample is directly proportional to discharge !low
rates or the sampling interval (for constant volume samples) is
inversely proportional to the flow rates over the time penod
used to produce the composite.
NA If 'CONY' was entered in column 6.
Analytical methods - Appendix A contains all parameters with
their reporting levels. test descriptions. and references. The parameter
values can be determined either by use of the standard analytical methods as
described in table A or by methods previously approved by the EPA Regional
Administrator or Director of a federally approved State program (or their
authorized representative) who has jurisdction over the State in which the
discharge occurs. if the test used is not one shown in table A, the test
procedure should be referenced in 'Remarks' or on a separate sheet. If
values are determined to be less than the detectable Omits (as determined by
referenced standard analytical techniques and/or instrument manufacturer's
literature). specify'LT(Vaiue of detectable limit)' in the ap repriate space.
For example, if the detectable limit is .005 mgll and quantities of less than
this are determined, specify'LT.005.' Do not enter descriptors such as
'NIL,' 'TRACE.' 'NEG.' etc. for this purpose. If it is your reasoned
judgement that one or more of the required parameters is not present in the - -
Initial untreated or treated process water and/or the discharge, enter an'A'
(meaning 'absent) in the appropriate space.
In order for values reported to be representative, it is
recommended that they be based on from at least fire to seven analyses of
composite samples(ifapplicable). Each of the composite samples should be
obtained by compositing frequent samples in proportion to lbw over an_
operating day. Samples should be taken during period of maximum
production, ' passib e:1f samples are taken at periods of less than -
maximum production, state in 'Remarks' the percent of maximum
production that was obtained during the sampfi grperiod.

Sludge Management Plan: Clariant Corp. - Mt. Holly Plant
This material has been prepared for inclusion in the plant's NPDES permit application.
February 27, 1996
There are two sources of solids in the wastewater treatment plant's process. One source is waste
activated sludge. The other source is from neutralization of acidic wastewater coming from the
manufacturing process areas. Below is a description of how the solids are separated, handled, and
disposed of.
Acidic process wastes are carried to the wastewater treatment plant via the facility's acid sewer system.
The acidic waste stream is contacted with lime to neutralize acidity. The neutralization process produces
calcium sulfate, which has very low solubility in water. The neutralized waste slurry passes into two
primary clarifiers operating in parallel. Calcium sulfate sludge settles out and the clarified water passes
into the activated sludge treatment system for biological treatment.
The activated sludge portion of the wastewater treatment plant has two aeration basins that operate in
series. Excess bacterial sludge from these units is wasted into the plant's alkaline sewer. The material
in this sewer is mixed with the already neutralized acidic stream prior to entering the primary clarifiers.
Both sludges are removed from the clarifiers by pumping them from the bottom where they settle. The
sludge slurry is stored in a holding tank. When the holding tank becomes full, normally three times a
week, sludge slurry is filtered on two automatic belt filter presses. The filters operate in parallel. Sludge
exiting the filters is routinely 43-53% dry solids.
The concentrated sludge is then hauled to a lined landfill cell on site for disposal by dump truck
transport. The lined landfill cell has capacity for approximately 5 to 6 more years of solids production.
There is space for five additional landfill cells in the area of the one now in use. Each cell is planned to
hold 7 to 10 years of solids dependent upon the production facility operation. Calcium salts make up the
largest portion of the solids that are landfilled. Waste sludge from the activated sludge system accounts
for 20-30% of the annual sludge production and calcium salts account for the rest.
