Mr. Thomas,

I apologize for asking you this so many times, but I want to check that Guardian is not claiming any information regarding the last 114 information request as confidential for any facility (including pull rates, lb/ton emission rates, etc.)Thanks,

Ms. Hancy,

Yes, HAP/Phenolic Binder was used in each of these plants when testing was conducted.

Mr. Thomas,

RTI is one of the contractors assisting EPA with the wool fiberglass NESHAP. After reviewing the formaldehyde, phenol, and methanol results of Guardian facilities, we would like to verify whether the testing below was completed while the bonded lines were running a HAP/Phenolic Binder.

Guardian Kingman – Testing performed 10/2005 Guardian Inwood – Testing Performed 11/2007 Guardian Albion – Testing performed 5/2008

Please feel free to contact me if you have any questions.
