### Below is an approximation for the processing of the New Chemical Substance by sites not under control by Emerald Kalama Chemical, LLC. The end product is a to be used by Additional processing steps and release points may be included in this process; however, these steps are not known or expecte d f rom the information we have been supplied.

Waste Point #6 Process Cleaning:

Customer production runs and turnarounds are expected be somewhat synchronized with the production campaigns for PICA at the Emerald Kalama Chemical, LLC facility. Thus a total of three complete process cleanups per year are expected. Cleanup media is likely hot water and steam. Recycle Stream Waste Point #3 Process Sampling:

The customer is expected to take samples from various unit operations of the process. After testing, samples will likely be collected for disposal via

incineration.

Waste Point #4
Distillation Waste:

Organic waste from distillations is expected to be incinerated. Hydrogenation Catalyst, Hydrogen Gas Waste Point #1

Drum and Other Shipping Container Waste:

PICA residues left in shipping containers are expected to be rinsed out with water and sent to a wastewater treatment facility.



### Filter Solid Catalyst, Organic Residues Waste Point #2 Catalyst Filter Waste:

Spent solid catalyst , filter material, and organic residues (including PICA) are expected to be separated: catalyst will be regenerated, filter materials will be landfilled or incinerated, and liquid wastes sent to a waste processing facility off

- site. Exposure Point "A" Offloading PICA Containers

Personnel are likely to be exposed to small amounts of liquid PICA and PICA vapors during the offloading of PICA from shipping containers to a storage tank. Drum offloading entails a higher degree of exposure than
other containers.

Exposure Point "C" Process Sampling

Personnel are likely to be exposed to small amounts of liquid PICA and PICA vapors when sampling material in the

process.

Exposure Point "D" Sample Testing

Personnel are likely to be exposed to minor amounts of liquid PICA and PICA vapors when testing samples from the process.

Exposure Point "E"
Process Maintenance

Personnel are likely to be exposed to liquid PICA and PICA vapors when performing maintenance to process equipment. Degree of exposure varies according to maintenance activity
involved.

Exposure Point "F" Process Cleaning

Personnel are likely to be exposed to liquid PICA and PICA vapors during process cleanup / turnaround activities. Degree of exposure will vary according to process technology and equipment being cleaned. PICA

Waste Point #5
Process Maintenance:

Process maintenance will involve cleaning of specific sections of the process with water and steam. Waste materials will likely be sent to a waste water treatment facility off
