Hi David,

I assume the provisions for pitch storage tanks only apply to facilities utilizing liquid pitch. Alcoa Rockdale does not

use or store liquid pitch.

Thanks,

Terry

Hello all,Thank you so much for taking the time to respond to the information collection request (ICR) dated April

25, 2011 concerning the primary aluminum operations conducted at your facility. The information you

provided will be instrumental in the ongoing associated residual risk /technology review. I have been going

through the ICR responses I received and have a couple of follow

- up questions concerning pitch storage

tanks:

1. The ICR did not directly ask whether or not your facility utilizes any new pitch storage tanks (i .e.

tanks installed after the proposal of 40 CFR Part 63, Subpart LL on 09/26/96)? Do you have any new

pitch storage tanks that are subject to Subpart LL at your facility? If so, what controls do you use to meet

the 95% POM reduction requirement in 40 CFR §63.844(d) [please submit this information on Table(s) 1

through 5 found in the ICR for the associated control device(s), if applicable]?

2. It appears, based on the ICR responses I received, that the ICR may not have been clear in

regards to submi tting information on any controls that may be installed on existing pitch storage tanks at

your facility that are subject to Subpart LL. If you have any existing pitch storage tanks at your facility that

are subject to Subpart LL and that have emissions c ontrols installed on them (even though those controls

are not required under Subpart LL) please provide the information necessary to evaluate those controls

[i.e. submit Table(s) 1 through 5 found in the ICR for the associated control device(s), if applica ble].

I am sorry for the need for this follow

- up email. Your time is valuable and I appreciate you taking time out

of your busy days to provide this information.

Thanks again,
