**Nick - There are really only two sources of Polymers & Res**  **ins IV SAN resins emissions at the KY Plant of any significance. All other vents have negligible emiss**  **ions. The main one, of course, is the Spray Dryer # 2 RTO vent**  **(SD2RTO) and the other is the Spray Dryer #2 RTO By pass (SD2BP). Spray Dryer #2 is used to dry both SA**  **N resins and NBR. All styrene emissions allocated to**  **these two vents are attributable to SAN resin manuf acturing.**  **The acrylonitrile emissions from these two vents ar e attributable to both product lines. The flow rate**  **s, exit velocities, temperatures, inside stack diameters, s**  **tack heights and locations have not changed.**

**Here are reasonable maximum annual emissions due to SAN resin manufacturing for these vents:**

**Tom,**

**Attached is a draft emissions data file that EPA is planning to use for modeling of P&R IV emissions f**  **rom your Louisville facility. This file was derived from emi**  **ssions data that was sent by you back in 2009 that was used in**  **Zeon's STAR modeling effort for the Louisville Metr o APCD. We have subtracted from the STAR data the**  **emissions from the ICR response EPA received for P& R I and assumed all the ethyl acrylate emissions ar**  **e for the polyacrylate rubber produced and regulated unde**  **r the MON, which leaves the rest of the emissions f or P&R**  **IV. We would appreciate Zeon's input on these emiss ions and please reassign any emission points that h**  **ave been incorrectly apportioned. The first spreadsheet**  **shows the emissions by MACT, the second shows the STAR** 
**data we received from you, and the third spreadshee t shows the ICR data received from you.** 

**We would appreciate if you could send us any revisi ons by June 4th. Thank you.**
