Mr. Backfisch,

How many days of extension are you requesting? Coul d I expect the results by 06/07/13 (i.e., a one

week extension)? As you mentioned, the tight court- ordered deadline for this rulemaking does not leave
me with much flexibility on scheduling and the diox in/furan, PCB and speciated PAH emissions data

from your facility will be critical to the assessme nt of risks from prebake primary aluminum smelters.

Would it be possible to submit any emissions data b y the May 31 deadline? That is, possibly some of th e sample analyses were not affected by the equipment problems and that data could be submitted on

time.

Also, I would appreciate receiving the preliminary emissions data as soon as possible so that we can
begin our analysis of the data. If you subsequently find any accuracy problems with the data we could

adjust the data appropriately later.

Mr. Putney,

Our stack testing contractor has informed me that t he analytical lab working on our samples from the ICR testing has had some equipment problem s and will not be able to provide our results in time to meet the May 31 deadline. Would it be possible to get a few days extension to allow us to receive the analyses, complete the subm issions, and review them for accuracy before submitting the data to you? We are aware of your very tight schedule and apologize for having to ask for more time to get our results to y ou.
