(EPA) is collecting information to characterize hazardous air pollutant emissions from process 

vents at polyvinyl chloride and copolymer (PVC) production facilities. 

PVC production is subject to the provisions of 40 CFR Part 63, Subparts HHHHHHH and 

DDDDDD. The purpose ofthis request is to gather process vent data and other information 

necessary to inform our reconsideration of these emissions standards. 

We request the following testing be performed for your PVC production facility, OxyVinyls, LP 

- Deer Park, TX as specifically listed below and discussed in Attachment B of Enclosure 1 

(tables 1.1 and 1.6) to this letter:

We are also requesting other information regarding PVC production at your facility and are 

providing the survey response forms in Microsoft® Excel spreadsheet format. Test results that 

are collected using test methods that are supported by EPA's Electronic Reporting Tool (ERT) 

must be submitted using the ERT. We are also providing PVC process vent response forms in 

Microsoft® Excel spreadsheet format for test methods that are not supported by the ERT. Please 

see Enclosure 1, Attachment B for specific ERT submission instructions. 

The requested testing is designed to collect information on emissions and other relevant aspects 

of PVC process vents. Enclosure 1 contains a summary of the information we are requesting.
