Mr. Putney,

The pitch storage tanks at Alcoa, Warrick Operations are using natural draft displacement with no controls, and 

exhausting to atmosphere. Alcoa, Warrick has not installed any new tanks either.

If you need any other information please feel free to ask.

Thanks,

Chris Allen

Subject: Follow up on pitch storage tanks at PAL facilities

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 submitting 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 controls 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 applicable].

I am sorry for the need for this follow-up email. Your time is valuable and I appreciate you taking time out 
2

of your busy days to provide this information.

Thanks again,
