Inspection Summary:
Permit and Outfalls (cont.)
The inspection was conducted during dry weather and no discharges were detected at Outfalls 001, 003, 004, and 005.
However, an illicit discharge was noted in Outfall 006 during the inspection.
An unknown brown, oily, liquid with yellow foam was noted in the flared outlet of the concrete discharge pipe for this
outfall and in the riprap and earthen sections of the discharge channel. The unknown liquid had mixed with Catawba
River water, which resulted in a brown liquid with trace foam on the surface. The stormwater collection system was traced
immediately upstream where a gate valve had been installed and the contents of the collection system could be easily
viewed. The same unknown liquid was noted in the collection system upstream of the gate valve and sand was placed at
the end of the collection pipe. Pictures of the unknown discharge are contained in last section of this report.
Clariant personnel were instructed to remove the unknown liquid from the stormwater collection system, outfall, and
discharge channel and to take measures to prevent further discharge.

Comment: The list of spills on site was current as of the date of the last SPPP review
(December 17, 2007) and included a note to include the January 2008 pre-treatment
spill, which reached a storm drain, when the SPPP is next revised.
All required secondary containment is provided with many of the tank farm containment
areas draining to the chemical sewer and the on -site pre-treatment facility.
The permittee has segregated stormwater on site with a portion flowing to the chemical
sewer onsite and "clean stormwater allowed to discharge through the designated
outfalls along with cooling tower blowdown permitted under NCG500047.
Employee training is conducted annually and includes a detailed written test regarding
the requiremonts of the stormwater permit.
The Spill Prevention and Response Plan requirements are met through the creation and
implementation of a SPCC plan and included by reference in the SPPP.

Comment: The permittee has designated six outfalls (001, 002, 003, 004, 005, and
006) on site that discharge to the Catawba River. A seventh outfall has been
designated but it receives water from the Town of Mt Holly collection system and
discharges the water to the River through Outfall 006. The permittee has the ability to
prevent unwanted discharges through valves on the stormwater outfalls. The permittee
recently installed a gate valve on Outfall 006. A visual inspection was made on all
outfalls except for Outfall 002, which is not currently being used.
Additional information regarding the Permit and Outfalls is contained in the Summary
section of the inspection report.

Additional Comments, Observations, Conclusions, etc. (attach additional sheet if necessary):
Fish Kill was originally called in by Rowboat Dock and Dredge which was building a dock at the end of Riverfront
Pkwy in Mt Holly. This location is 2 miles downstream from hghest point where fish were noted just downstream from
Outfall 006 at Clariant West Facility in Mt Holly. A specific count of fish and #/species was not done. Approx. 2,000
fish (carp, catfish, shad, bluegill, bass, crappie and one snake) were observed dead and bloated on 5/30/08. Live fish
were noted on 5/30/08 so kill most likely occurred night of 5/28 and morning of 5/29. Water quality readings on 5/30/08
were within normal levels. From stormwater inspection of 6/3/08 DWQ found chemicals in Clariant West Facility
Outfall 006 that may have been released during rain storm on afternoon/evening of 5/28. Both products that could
have been discharged are highly toxic to fish with LC50 values of 0.1-1.0 mg/L.

June 5, 2008 — Phone Conversation between Mr. Gil Insley (Clariant Corporation)
and M. Allocco (DWQ)
Mr. Insley reported that Clariant had completed the clean up of the stormwater outfall
which took approximately 3 hours. Two samples were taken for analysis, one in the
stormwater outfall and one in the outfall pipe upstream from the gate valve at outfall 006.
Mr. Insley stated that the cause of the release witnessed on June 3, 2008, was from a
failed sump pump, which due to the piping in the area near Plant 5 overflowed liquids
destined for the chemical sewer to the stormwater system, which drains to Outfall 006.
Mr. Insley stated that the piping had been reconfigured to drain to the containment area
for the chemical tank farm and that area drains to the chemical sewer. Mr. Insley further
stated that there could have been chemicals in the same sump that may have
overflowed on May 28th and caused the fish kill. Mr. Insley stated that no one at the
company knew about the discharge because the piping was underground. Mr. Insley
stated that Clariant thought that they had satisfdctury redundancy in the area to prevent
such a spill.
June 5, 2008 — MRO staff received anonymous call regarding fish kill in the
Catawba
MRO staff was told that a bad batch of material was manufactured at the Clariant West
facility on May 28, 2008, which got into the sump at Plant 5 and was discharged to the
Catawba River. The sump overflowed due to the rainstorm in the Mt Holly area (1.5")
that overwhelmed the sump pump.
June 10, 2008 — Follow-up inspection
This was a follow-up visit to the June 3, 2008, inspection to review the progress in
removing the illicit discharge at Outfall 006. All soil and contaminated rock has been
removed from the discharge channel and the entire channel and banks had been filled
with riprap. There was no evidence of any residual contamination in the outfall pipe
upstream of the gate valve for Outfall 006, which held the majority of the unknown liquid
on the June 3, 2008, inspection. The piping has been reconfigured at the sump for Plant
5 so that overflows do not go to the stormwater system discharging to Outfall 006 but
rather to the tank farm containment area and eventually to the chemical sewer. Possible
chemicals in the unknown liquid of June 3, 2008, included air scrubber materials
including caustic and two C12-C18 amines. Possible candidates include Genamin LA
302 D and Genamin T 100 both of which have a LC50 for fish of 0.1 to 1.0 mg/L.
Clariant released a press release on June 12, 2008, taking the blame for the fish kill of
May 29, 2008, on Lake Wylie.

June 12, 2008
On June 3, N.C. Division of Water Quality (DWQ) representatives visited industries with plants located
along the Catawba River in the Mount Holly area, including Clariant, in follow-up to an unexplained fish
kill that occurred on the river on or about May 29.
During this visit, Clariant and the DWQ representatives together discovered residues of materials used to
make soap and cosmetic ingredients in a permitted stormwater drain that flows to the Catawba River.
Some of the residues are generally considered to be toxic to fish.
As a protective measure, Clariant environmental personnel immediately blocked the drain at the river's
edge to prevent any flow of water through it, completely cleaned the drain to remove all residues, and
removed potentially affected soil from the base of the drain.
A subsequent internal investigation by Clamant determined that the, presence of the soap -making
ingredient was caused when a pump and an eleUvo-aic level detector malfunctioned, resulting in an
overflow into the drain.
The malfunctioning pump and level detector were immediately repaired and tested and all other drains,
pumps and level detectors in the manufacturing building where the malfunction occurred have been
thoroughly inspected and tested. The system was modified to prevent overflow to stormwater in the event
of power failure or other malfunction.
Clariant has informed its local community advisory panel, the Catawba Riverkeeper, Charlotte -
Mecklenburg Storm Water Services, Mount Holly City officials and Gaston County's state legislative
delegation about the situation.
Because it is unknown when, or in what amount, material may have entered the river, Clariant cannot
conclusively link the material found in the stormwater drain to the river incident. However, the soap -
making ingredients should not have been in the stormwater drain.
Regardless of the uncertainty over the cause of the fish kill, Clariant wishes to assure the community of
its commitment to be -a responsible --corporate citizen. Clariant will be working with the N.C. Fish &
Wildlife Commission to determine what voluntary steps might be appropriate for the company to take to
...................accist_in.reblailding 6e fieh population in that 5-Aluu of tlic Catawba River.
The Clariant Mount Holly plant has been a member of the Mount Holly community since 1953. The
Plant manufactures a wide variety of ingredients for soap, cosmetic and personal care consumer products.

This e-mail is to follow up on my phone calls to report a wastewater spill.
The spill occurred at the wastewater pretreatment facility of:
Clariant Corporation
625 East Catawba Avenue
Mount Holly, NC 28120
Wastewater pretreatment Industrial User Permit # 1158
Stormwater permit # NCS000041
The spill was discovered at approximately 03:00 on January 3, 2008. The
material spilled was treated wastewater. The wastewater was leaving the
sand filter, which is the last step in the pretreatment process before it
is sent to the City Of Mount dolly POTW.
The cause of the release was a broken sight glass on the sand filter.
The quallLiLy released is initially estimated Lo be 5000 gallons. Of that,
an estimated 50 gallons flowed into a storm sewer, which discharges to the
Catawba River, and an estimated 500 gallons escaped into a grassy area on
site. The remainder was contained in a sump and pumped back into the
headworks of our wastewater treatment facility.
To stop the spill, our wastewater treatment equipment was reconfigured to
bypass the sand filter, as designed. The sight glass will be repaired and
then the sand filter will be put back into service.
The following phone calls were made today to report this spill:
11:56 - Mount Holly POTW
12:01 - Gaston County Emergency Management
12:06 - NC DENR, Mooresville Regional office
There is no requirement to contact the State Emergency Response

The area adjacent to outfall 001 was observed to be used for
the storage of chemical drums. A paved area funneled storm water
drainage from this area into the discharge pipe. The potential
for discharge contamination and a direct route for spills to
enter the river exist. The Company has been requested in a CEI
dated December 20, 1989 to take corrective action.
