Sent: Friday, February 07, 2014 11:14 AM To: 'Howard.Jodi@epamail.epa.gov' Cc: Pryor, Jadie L.; Strain, Deanna K; Krishna, Chris Subject: RE: OxyVinyls (Deer Park, TX) CAA 114 Test Plans - Part 1 Jodie, In our conversation on Wednesday you indicated you lacked data for some of the facilities controlling combined PVC plant and other vent gas streams. In one of our prior meetings, we indicated 2008 HCL/Cl2 test data submitted with our original test plan for our Deer Park/LaPorte location may have been over looked. You also mentioned that you have a new Email system and some of your prior Emails may not have transferred properly. Enclosed is the original stack test plan for our Deer Park PVC plant which sends vent gas to our LaPorte EDC/VCM plant. It contains a summary of prior June 2008 HCL/CL2 test data (page 6-1) that was approved by EPA to be used in lieu of additional 2009/2010 HCL/CL2 testing. As indicated below, a copy of the actual 2008 test report was provided on CD which was submitted to your office separately. The purpose of our 2008 testing was to demonstrate compliance with our TCEQ permit limit after rebuilding our scrubbers. For convenience, I added a copy of our 2008 test report to this mail. You also had inquired about estimated costs for some additional stack testing which I have not yet been able to assemble. If you have questions, please contact me.

Barry, In your October 8, 2009 letter, you requested that the OxyVinyl Deer Park facility be granted a 45 day extension "to collect the required information and submit the survey response." We will not be granting your request for a 45 day extension for the Deer Park facility's 114 PVC survey response. The survey is due on November 30, 2009. However, we are granting you an additional three weeks to submit your PVC test plan for the Deer Park facility. The test plan is due to EPA by November 10, 2009. As we previously discussed, you may request that existing stack test data be considered in lieu of testing. With this request, you must indicate which parameters you wish to use existing test data for and specify the methods that were used. You must also submit test reports and any other documentation to support your request. Attached to this email, is an example of EPA using area source emissions data to develop a major source NESHAP. The attachment is the final Brick and Clay Products NESHAP preamble [68 FR 26690, 26697-98 (May 16, 2003)], which contains a discussion of the issue.

Thanks.
