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.

What type of emission sources are there from your back-end 

processes?

Do you have any permit limits or conditions for the 

emissions from the back-end process operations?

Back-End Process Operations

Have you verified and/or corrected the back-end process 

operation emissions for your P&R I processes in the dataset?

Have you completed all control information fields for your 

P&R I back-end processes in the dataset?

What emissions calculation approach was used to estimate 

the back-end emissions?

Are the back-end process operations continuous or batch?

If the back-end process operations are batch, what is the 

operating schedule (hrs/yr) (please use the base year 

identified in "Facility Information")

Please describe the back-end emission processes at this 

facility (i.e., the operations in an EPPU following the

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?

annual emissions from startup and shutdown events that you added in the "STARTUP EMISSIONS (TPY)" and
