Halobutyl (HBR EPPU) and Vistalon (EPR EPPU) rubbers enter backend in a water slurry. Water is separated from the rubber via extruders. Rubber is conveyed via air conveying systems, and then compressed into bales for shipment to
customers.

If "Other", please explain: Engineering calculations for HBR EPPU and lab analysis for EPR EPPU.

Not applicable

If yes, what is the limit/requirement and how are you required to demonstrate compliance (e.g. source testing, continuous emissions monitoring, continuous or periodic parameter monitoring, etc)? Please describe or provide a copy of these requirements.

Portions of emissions from Halobutyl backend are controlled by a regenerative thermal oxidizer. Temperature of this control device must be maintained >1600oF (daily average). Permit also allows for 50 tpy of VOCs and 40.1 tpy n-hexane emissions during control device maintenance. Permit limits for regenerative thermal oxidizer (S-88) are as follows: VOCs = 63.5 tpy; n-hexane= 49.8 tpy ; HCl = 0.2 tpy HCl. Uncontrolled portions of Halobutyl backend include the following source: V-127 (Permit limits = 48.38 tpy VOCs; 33.87 tpy n-hexane) and V-131 (Permit Limits = 22.5 tpy VOCs; 16.9 tpy n-hexane)

The emissions from the Vistalon backend meet the regulatory requirement of 0.8 kg/Mg [40 CFR 63.694(a)(3)((i)]. Back-end process operations emissions are not currently reduced further by a control device . Emissions are limited in the permit to 757.08 tpy VOCs and 615.7 tpy n-hexane.

Startup and Shutdown Events

If no for any of the above, please explain:

1) For equipment leaks, there are surge control vessels with closed vent systems/control devices that would need maintenance time allotments. 2) For front-end process vents and storage vessels, when opening process equipment to the atmosphere, then organic concentrations may be higher than limitations. 3) If back-end process operations are to require add-on control devices, then control device maintenance time allotments need to be included in the rule.



### Do you wish to recommend a standard that would apply during startup and shutdown? If so, please:

1) Anytime process equipment (containing HAPs) needs to be shutdown and opened for maintenance work. 2) Control device maintenance if back-end control devices are required. 1) Currently, no regulatory standards apply when opening equipment for maintenance. Current safety practice is to empty and purge equipment (that is tied to the flare system) and then nitrogen purge (to the flare) until the hydrocarbon vapor concentration in the equipment is less than 1% of the Lower Explosive Limit. 2) Allow up to 240 hours of control device downtime for maintenance if back-end (add-on) control devices are required.
1) Monitor with LEL gas detector prior to opening. 2) Keep records of control device downtime for maintenance. 1) Unit Safety Procedure 2) Other Part 63 rules for control devices (i.e. HON)

1) Purging equipment to this level would minimize emissions to a level that is practical to achieve for equipment tied to control devices. 2) Allowance of 240 hours control device downtime would utilize an existing standard from other MACT rules. 

### 5. Explain why and how the standard would minimize emissions during the event For each emission source type, can you comply with the emissions limitation and/or work practices in the regulation that apply during normal operation during startup and shutdown events?
