Dear Ms. Howard,

The VI has made prior comments on the potential bias that seasonal
production rates may introduce into the PVC MACT rulemaking.  The
attached letter documents some of those periods of seasonal production
for your consideration.  Please do not hesitate to contact me with any
questions regarding the information or its impact on the survey
responses.  Thank you for the opportunity to submit this document for
the PVC rule development.

Regards,
