Dear Mr. Insley:
We have completed a review of your request for modification and renewal of your general permit
coverage under Certificate of Coverage (COC) NCG50047. This modification consists of the following
changes from your previous permit coverage:
➢ A cooling tower will be relocated, and will therefore discharge through Outfall 006 instead of
Outfall 003.
➢ A new boiler and cooling tower will discharge through Outfall 003.
➢ The addition of the following biocides:
■ Chemtreat BL-122 (Outfalls 001 and 003)
• Chemtreat BL-1543 (Clutfalls 001 and 003)
• Chemtreat BL-1770 (Outfalls 001 and 003)
• Caustic Soda Liquid (Outfalls 001 and 003)
■ Chemtreat CL-1432 (Outfalls 001, 003 and 006)
■ Chemtreat CL-2150 (Outfalls 001, 003, and 006)
• Chemtreat CL49 (Outfalls CO3 and 006)
The permit application also requested the addition of Chemtreat CL-49 at Outfall 001, however
based upon submitted calculations, the addition of this chemical at the proposed dosing rates was
determined to result in toxic impact to aquatic life. In a follow-up email, you indicated that Clariant
would not use CL-49 in any equipment that discharges to Outfall 001. If a situation calls for the use of
that chemical, wasteflows would be routed to the onsite wastewater plant rather than be discharged
directly to the river.
In accordance with your application for discharge, the Division is forwarding herewith the subject
Certificate of Coverage to discharge under the subject state-NPDES general permit. This permit is issued
pursuant to the requirements of North Carolina General Statue 143-215.1 and the Memorandum of
.Agreement between North Carolina and the US Environmental Protection agency dated May 9,1994 (or
as subsequently amended).
The following information is included with your permit package:
A copy of the Certificate of Coverage for your treatment facility
A copy of General Wastewater Discharge Permit NCG500000
A copy of a Technical Bulletin for General Wastewater Discharge Permit NCG500000

CL-49 is a backup treatment chemical that will not normally be used. It
was only requested in case it is needed to address some unusual situation.
Because it failed toxicity, our plan is that we will not use it in any
equipment that discharges to Outfall 001. If there is some severe
situation which demands the use of CL-49, then we will discharge to our
on -site wastewater treatment plant, instead of to the river. (We are piped
to be able to do that).
So to answer your question, no we will not modify the dosage rate. We will
simply eliminate the use and/or discharge of that chemical. None will ever
be discharged to the river.

Cindy's memo approves all of the biocides listed except Chemtreat CL-49
at outfall 001. She stated that the product at the proposed dosage rate
is unacceptable for use. The dosage rate at the other two outfalls is
fine. Were you planning on modifying the dosage rate at 001 in response
to her comments?
Thanks,

still need to receive some sort of letter and Certificate of Coverage from

Calculations summarized on the accompanying worksheets predict the use of these products, at the stated
dosage rate, will not cause toxic impacts to aquatic life in the receiving stream, Catawba River, except for the
Chemtreat CL-49 used at outfall 001. That product at the stated dosage rate is unacceptable for use. That same
product is used at the other two outfalls but at a lower dosage rate and is acceptable.

Subject: Renewal — Certificate of Coverage # NCG500047
Clariant Corporation — Mount Holly West Plant
Dear Mr. Weaver:

r
I recently received from you an application package for the renewal of our Certificate of
Coverage (CoC), number NCG500047. A due date of February 1, 2007, was given for submittal
of our Notice of Renewal Intent (NORI).
Your letter states that we may disregard your notice if we have already mailed a renewal request.
On November 16, 2006, I submitted a complete Notice of Intent (NOI) related to proposed
modifications of our discharge sources. I have received confirmation from Toya Fields of the
DWQ that the NOI was received and is being processed. Also I have been in contact with Cindy
Moore of the Aquatic Toxicity Unit regarding that unit's review of the NOI.
Because the NOI application that is currently in process contains all of the information required
by the NORI, it seems redundant and perhaps even confusing to submit an additional NORI at
this time. Based on these circumstances and the statement in your renewal notice, I conclude that
Clariant has already fuifllled the requirements for timely submittal of an NORI.
If you would like to receive additional information or discuss this further, please contact me.
Thank you for your assistance.
Sincerely,
G� /oat

Subject: Notice of Intent
Permit Modification - Permit # NCG500047
Clariant Corporation — Mount Holly West Plant
Enclosed are three copies of a Notice of Intent (NOI) application for modifications to our
NPDES permit number NCG500047. Additionally, one copy is being sent to the Aquatic
Toxicity Unit as was recommended to facilitate their review of the Biocide 101 forms.
Clariant currently has six permitted stormwater outfalls that discharge to the Catawba River.
Two of those outfalls are also permitted under NCG500047 to discharge non -contact cooling
water and cooling water blowdown (Outfall 001 and Outfall 003). One outfall is also
permitted to discharge boiler blowdown and condensate (Outfall 001).
There are several reasons for this modification request:
We intend to move one cooling tower to a new location. Instead of discharging its
blowdown through Outfall 003, it will discharge through Outfall 006.
2. We are installing a new boiler and a new cooling tower. Both will potentially
discharge through Outfall 003.
3. We have changed suppliers for our water treatment chemicals. As a result, there are
minor differences in the chemicals that are used to treat our boilers and cooling towers,
and which are present in our blowdowns.
4. We would like to add one new chemical (bromine chloride) to our cooling tower
treatment options. This is to allow us some flexibility in the event that we encounter a
situation where this new chemical might be beneficial.

In addition to the NOI, this application package also includes three copies of the Biocide 101
form for each water treatment chemical used at each boiler and cooling tower. Also included
are three copies of the topographic map, the site map, an alternatives analysis, MSDSs, and
other supplemental information required. Finally, our check for the $80 permit application fee
is included.
If possible, I would appreciate if you could send me a brief e-mail confirming that this
application has been received and is in process, and the name of the person who will be
working on this application. We respectfully request a prompt approval of this permit request
in order facilitate our implementation of the requested modifications. However, we recognize
that there are a number of steps in the approval process and we have allowed six months
before we absolutely need our permit in order to start up new operations by May 2007.
If you have any questions or require any additional information, please contact me at the
telephone number or e-mail address shown below. Thank you for your assistance.

NOI Item # 9 (Biocide 101 Forms)
Biocide 101 Forms and MSDSs are included with this submittal.
NOI Item # 10 (Treatment Prior to Discharge
Outfall 001 has a valve that can be switched to direct flow to the on -site wastewater pretreatment
facility (WWTP) instead of to the river. Also, two of the cooling towers that can discharge
through Outfall 001 are designed with the option of directing blowdown to the chemical sewer
(which leads to the WWTP) instead of the storm sewer (which leads to Outfall 001).
Outfall 003 has a 24,000 gallon concrete stormwater retention pond. The valve to the river is
opened as needed after the water is inspected for any evidence of contamination. The capability
also exists to pump the contents of this pond to the WWTP. Also, the cooling tower and the
boiler that can discharge through Outfall 003 will also be designed with the option of directing
blowdown to the chemical sewer (which leads to the WWTP) instead of the storm sewer (which
leads to Outfall 003).
Outfall 006 does not have any treatment capability other than a gate that can be used in an
emergency to delay a small amount of discharge from entering the river.
Note: All "treatment" systems described above consist of standard sewer piping, valves, and a
retention pond that have long been in service at this site. Blowdown is not really being treated
before discharge; rather it is being conveyed and sometimes contained before discharge. No new
treatment facilities are being constructed. Signed and sealed construction plans and specifications
are not applicable to Clariant's "treatment" systems and none are being submitted with this
application.

NOI Item # 14 (Alternatives to Direct Discharee
Outfall 001 is controlled in a manner that directs most blowdown water to the on -site wastewater
pretreatment facility (WWTP). Outfall 001 has a valve that can be switched to direct flow to the
WWTP instead of to the river. Normally this valve is kept in the position of being closed to the
river. This means that blowdown water will normally flow to the WWTP. The valve is only
opened to the river during periods of hard rain. It is estimated that less than 5% of blowdown
water actually flows to the river. Additionally, two cooling towers are piped with the capability
to direct blowdown directly to the chemical sewer, which has no path to the river at all. This
piping is not used often, but it is available if needed. Because of the piping arrangement that
directs most blowdown flow to the WWTP, Clariant considers that a desirable alternative has
already been identified and implemented. No further evaluation of alternatives is necessary.
Outfall 003 has a 24,000 gallon concrete stormwater retention pond with a valve to shut off flow
to the river. The valve is normally closed to the river. There is existing capability to pump the
contents of the retention pond into the WWTP if necessary. Additionally, both the boiler and the
cooling tower that potentially discharge their blowdowns to Outfall 003 will be piped with the
option to direct their blowdowns directly to the chemical sewer. As long as the WWTP is
operating normally and is capable of handling the blowdown flow, the blowdown can be directed
to the WWTP instead of to the river. Because of the piping arrangement that directs a significant
portion of blowdown flow to the WWTP, Clariant considers that a desirable alternative has
already been identified and is being implemented. No further evaluation of alternatives is
necessary.
Outfall 006 is more problematic in terms of alternative discharge options. Clariant currently
plans to discharge all blowdown from the one cooling tower at this location to the river.
Connection to a municipal sewer system is dismissed as cost prohibitive based on Clariant's past
experiences with sewer piping work. Subsurface disposal seems to offer little benefit, since the
location is in close proximity to the river. Spray irrigation is impractical given the amount of land
area available at and around the site and is also of limited benefit. Connection of the blowdown
piping to the site's WWTP is feasible although somewhat costly and there are concerns about
overloading the WWTP which may soon be operating at near capacity. Clariant's qualitative
assessment is that the benefit of pumping and piping blowdown from this cooling tower to the
WWTP does not justify the cost and risk of building such a system. Note that this cooling tower
is already currently permitted to discharge to the river (at Outfall 003).
Clariant's overall requested permitted blowdown discharge is 32,700 gpd, and approximately
77% of that discharge normally is or can be diverted to the WWTP. All blowdown discharges are
through existing stormwater outfalls that are already in use, and thus no additional discharge
points are being added to the river. The blowdown discharges requested are low concentration,
low risk wastewaters that easily meet the State's discharge criteria and do not contain any
domestic wastewater or chemical production wastewater. In Clariant's judgment, these factors
constitute a substantial alternative to discharging to the river and Clariant's efforts meet the intent
of the alternatives analysis requirement.

Mr. Weaver,
Thank you for responding yesterday to my phone call. (I had originally
called Bradley Bennett last week). I, believe that I have answered most of
my questions from reviewing the DWQ's web site and speaking briefly to
Adu-Poku Agyeman at the MCIC water quality training sessions in Raleigh
last week. To be sure that I am headed in the right direction, I will
briefly summarize my situation below. -
My facility currently has a certificate of coverage (NCG500047) under the
State's general permit for non -contact cooling tower and boiler blowdown
(NCG500000). We are making the following changes to our discharge.
(1) We are moving an existing cooling tower to a new location. As a
result, it will discharge it's blowdown to the river through a different
outfall .
(2) We are installing a new smaller cooling tower to replace the one being
moved. This will potentially blowdown to the river through the same
outfall previously used by the existing cooling tower.
(3) We have replaced another existing cooling tower with a smaller cooling
tower. This is probably irrelevant to our permit because this cooling
tower does not discharge to the river.
(4) We are installing a new steam boiler that will potentially blowdown to
the river.
(5) We have changed water treatment chemical suppliers. The actual
chemicals, quantities, and concentrations have not changed, so this should
not affect anything, other than to update the record.
The reasons for these changes are (a) to accomodate some new production and
(b) to move some production to a different part of our site, and (c) to
improve operating efficiency.
It is my understanding that we will need to submit an NOI and supporting
documentation (including Biocide Form 101). Please confirm that this is
correct and let me know if there are any additional requirements.
One additional question is: to whom should I send my completed application
? We are under time constraints and I want to make sure that my
application goes to the appropriate person so that it is acted upon in a
timely manner.
Thanks you for your assistance.

Dear Mr. Insley:
We have completed a review of your request for modifications to your existing general permit coverage under
Certificate of Coverage (COC) NCG500047. This modification consists of the addition of a cooling tower with
non -contact cooling water to be discharged to outfal1003.
As part of our review, data submitted with your Notice of Intent concerning the dosage rate of biocides, degradation,
system volume, average daily discharge, toxicity of the active ingredients and minimum stream Flow have been
evaluated by our Aquatic Toxicology Section. Based upon submitted calculations, the use of Nalco 7346 will result
in toxic impact to aquatic life in the receiving stream and is, therefore, deemed unacceptable. Conversations
between representatives of Clariant Corporation, Aware Environmental and Mr. Todd Christenson of our Aquatic
Toxicology Section resulted in the withdrawal of Nalco 7346 for use. Revised information was submitted for review
that consisted of an increase in the dosage rates for Nalco 7330. A review of the resubmitted information predicts
that the use of Nalco 7330 at the stated dosage rates and discharge conditions will not result in toxic impact to
aquatic life in the receiving stream and, therefore, is deemed acceptable.
With the revisions described above, modification of the existing permit coverage under NCG500047 is granted.
Issuance of a new COC is not necessary. The modification will be covered under the existing COC issued to the
facility. Please remember that all outfalls should be sampled in accordance with the terms of General Permit
NCG500000, unless representative outfall status has been granted.
If you have any questions, please do not hesitate to contact me at 919n33-5083, extension 584.
