### From: "Pettis, Mike" < mike.pettis@owenscorning.com > To: Susan Fairchild/RTP/USEPA/US@EPA Date: 02/29/2012 12:41 PM Subject: 114 Request

Susan, I want to thank you for the extension and inform you that all test results and forms should be delivered to you by noon tomorrow. Here is a summary of the results. There are two items I want to point out. The A3 furnace is permitted for replacement wit h a furnace of the same design as the Mt. Vernon designs. A3 presently has an integral batch heating system of Owens Corning design and is the only one of its kind ever built. The data that I previously submitted for crown chrome content on DM1 was an er ror. We have done a temporary repair to that crown which I did not have data on at the time of submission due to the decisions made in the field. I will be updating that submission.
