Thanks From: Evans, Aaron Sent: Monday, May 22, 2017 3:20 PM To: Walters, Hope <Hope.Walters@kuraray.com> Subject: RE: New Imbibing Process Hi Hope, Per our conversation please see below. Below is process concept schematic for Etown warehouse. Process is same as previously communicated, but there is no consideration of silos. If performed at Etown warehouse, the process will always terminate with filling of Gaylord boxes with imbibed resin. 1 • • DEQ-CFW 00065366 Imbibing Process Schematic for SG5500 (ET Warehouse) Ir-------------------- lift 1 **Silane iMetering 1 Pump (blew) ' Model MSA 1 1 1 � 1 � 7ft Virgin 1 _ 1 1 AE-1028 • 1 Gaylord Box ; A i ------------------------------------ 4 *Roper wfbag filter (New) r s p r Knife gate valve (new) i -- -- - Lass -In -Weight Feeder (New) i i MPM Premixer (New) Model 5� E Imbibed AE-1028 Gaylord Boxes (Dual Loading System) * vacuum 3 corweying system with spare pump (new) aTh' � _ e '-------------+ The Sweeper Silane Imbibed resin boxes to System Feed DRUM storage area a- =p ng i�s:em a^aerates r:ith a From (New) lave; cxvo i- the recer.,—g nDrpe- Maguire ' • The i-tar;ac? for Si a-e ^i eterng (New) pumC "o: shc:-s Please see email below concerning rates, as demand and imbibing rates are not affected by changing location.

And, the subsequent worst case • ethanol or methanol emissions in each silane case. Here you go: The below numbers use projected demand of new resin product and the aforementioned maximum emission rate of ethanol and methanol of each silane product. 2018 Projected demand for NEW SG = 1085000 kg _> 2018 Silane consumption @ 1000ppm= 1085 kg _> 2018 MAX methanol emission= 336.35 kg _> 2018 MAX ethanol emission= 401.45 kg DEQ-CFW 00065368 2019 Projected demand for NEW SG = 2456000 kg _> 2019 Silane consumption @ 1000ppm= 2456 kg _> 2019 MAX methanol emission= 761.36 kg _> 2019 MAX ethanol emission= 908.72 kg Now, if we assume that every KG of SG made in either year is made with the new resin: that production value is based on historical SG production 2018 Total projected SG sheet production = 3200000 kg _> 2018 Silane consumption @ 1000ppm= 3200 kg _> 2018 MAX methanol emission= 992 kg _> 2018 MAX ethanol emission= 1184 kg I hope these calculations are helpful. Let me know if you have any questions. Regards, Aaron • Aaron Evans Mechanical Engineer Kuraray Interlayer Solutions Kuraray America, Inc.

Basically, this process will feed the currently used resin into a small blender, where silane will be injected at 1000ppm via a small metering pump. Attached is the SDS and the emissions of the ethanol or methanol emission of the two current silane options are as follows: Silquest A-2120 max emissions are 310g/1kg of McOH; CoatOSil 2287 max emissions are 370g/1kg of EtOH. The projected volume for SG6000 for 2018 is 1,085,000kg and for 2019 is 2,456,000kg. This means our consumption of silane for those two years will be 1/10001h of those values. This process will take place in ambient conditions for temperature and pressure considerations. I know you spoke with the Engineer on the project (Aaron Evans). I am submitting this to you so that you can provide guidance on anything that we need to do so that we can use this new process. Wasn't sure if we needed to add this to our existing permit, do a modification or if anything is required. Please let me know how we need to proceed and if you have any further questions please let me know. Best regards Hope A.
