In response to your questions below:

1. Ormet does not use any new pitch storage tanks

2. Ormet does not have any controls on existing pitch storage tanks. The process is currently not operating.

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 alum inum operations conducted at your facility. The inform ation 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 fo llow-up questions concerning pitch storage tanks: 1. The ICR did not directly ask whether or not your facility utilizes any new pitc h 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 Su bpart 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 info rmation 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 rece ived, that the ICR may not have been clear in regards to submitting informati on on any controls that may be in stalled on existing pitch storage tanks at your facility that are subject to Subpart LL. If you have any existing pitch stor age tanks at your fa cility that are subject to Subpart LL and

that have emissions controls installed on them ( even thou g h those controls are not required under Subpart LL ) From: "John Reggi" <John.Reggi@ormet.com>
