SUBJECT: Meeting Minutes for the EPA and Trade Group Meeting to D iscuss the

Proposed Voluntary VCM Program (23 April 2008)

EPA participated in a meeting with The Vinyl Institut e (VI) and several member companies (referred to as the Vinyl Chloride Producers, or VCP) on April 23, 2008 to discuss the sampling standard operating procedures (SOPs) developed by the VCP. The list of meeting participants can be found in Attachment A.

Background

EPA and the VCP initially met on March 14, 2007 to discus s the VCP’s proposed voluntary monitoring program (VMP) for vinyl chloride manufa cturers. Industry had proposed collecting dioxin and furan and total suspended solids (TSS) da ta for facilities’ final outfalls at a frequency of one sample per month for nine months. At t he March 14 meeting, EPA expressed concern about the potential for dilution at the final ou tfall since many of the facilities discharge wastewater from non-chlorine and chlorinated hydrocarbon (CCH) manufacturing operations. EPA prepared a generic sampling plan to describe their suggest ed approach for sampling and provided it to industry for discussion and comment. For fac ilities where CCH wastewater is commingled with non-CCH wastewater, EPA is requesting th at the facility collect a sample prior to the mixing point. EPA noted that the number of sampling points will depend on the facility’s manufacturing processes and process flow diagrams. EPA i s requesting that industry collect at least four samples at each sampling point, each collect ed at least one month apart.

EPA developed site-specific sampling plans for each fac ility in the VMP. These site-specific plans are confidential business information . EPA discussed the site-specific plans with each site and developed a final plan which the sites will use as instructions for the sampling. To ensure the twelve VMP sites collect samples consis tently, the VMP developed the five SOPs

listed below:

• VCP-1: Grab Sampling Guidelines;

• VCP-2: Compositing of Liquid Grab Samples;

• VCP-3: Synthetic QA/QC Sample Handling Protocol;

• VCP-4: On-site Automatic Composite Sampling Guidelines; a nd

• VCP-5: Analytical QA/QC Requirements.

The purpose of this meeting was to discuss the SOPs. The V CP is currently finalizing the SOPs prior to initiating sample collection. Final copies of t he SOPs will be entered into the Chlorine and Chlorinated Hydrocarbon rulemaking record.2

Discussion

Mr. Jim Williams, Dow, presented an overview of VCP’s sampling status (Attachment B). The twelve VCP facilities will be using three different la boratories. The VCP selected Environmental Standards in Valley Forge, PA to review and v alidate the results from the

laboratories. Environmental Standards will receive Level 4 reports from the laboratories for review. Each company in the VMP has already sent a QA sample to their laboratory to ensure the lab is qualified to perform the analysis.

Mr. Williams explained that the VCP has developed five sa mpling SOPs to ensure accurate,

consistent results and that the SOPs will be used in c onjunction with EPA’s Generic Sampling Plan and the site-specific sampling plans. The VCP is building a database to house the sampling data collected but they are still working through confidentia lity issues and whether they can share data between companies.

1. The VCP asked if EPA would like interim reports. EPA sta ted they would like to be notified when sample collection begins but will only need a final report from each

company.

2. EPA and the VCP discussed each of the five SOPs. EPA did not have any major

comments on the draft SOPs. The VCP will conduct sam pling training for the staff collecting the samples. Some facilities will be usin g contractor staff for the sample collection. The VCP plans to add discussions of foaming issues, clean techniques, and safety issues to the existing SOPs.

3. The VCP will develop final site-specific instructions for their sampling staff to use and will include these instructions in their final data packa ge to EPA.

4. The VCP asked about the sampling frequency. They may want to sample more frequently than once per month based on operating modes. EPA stated that individual companies can decide when it is appropriate to sample an d should note the reasons for the selected dates in their final data package (e.g., di fferences in operating modes, production). EPA is assuming that all sampling will be co mpleted within 15 months of receipt of the letter transmitting the site-specifi c plans (approximately May 2009). Most companies do not think there will be problems with mee ting the schedule barring unforeseen circumstances (e.g., force majeure e vents).

Next Steps

1. The VCP will complete the SOPs.

2. Each company in the VMP will notify EPA when sampling be gins.Appendix A. List of Participants
