Dear Mr. McLerran,

The Oregon Department of Environmental Quality (DEQ) is in the process of a rulemaking that proposes to adopt new and amended federal NSPS and NESHAP standards and related permit rules. This includes adopting new NSPS and NESHAP standards for electric utility steam generating units, gold mine ore processing and production, polyvinyl chloride and copolymers production, and sewage sludge incinerators, as well as changes to the gasoline dispensing facility NESHAP. The rulemaking proposal would also clarify when and if Air Contaminant Discharge Permits are required for sources subject to NSPS and NESHAP standards.

This rulemaking affects Oregon’s stage I vapor balance requirements and ACDP program and therefore involves a State Implementation Plan change. However, these changes are not a relaxation of the SIP. Adoption of the new and existing NSPS and NESHAP standards will require updated delegation requests.

Attached is the draft cover memo for the public notice package and the draft rule language. You will be receiving a complete rulemaking package in the near future.

If you have any questions or comments you can reach me at (503) 229-6974 or email me at EBERSOLE.Gerald@deq.state.or.us.

Sincerely,

Gerald C. Ebersole

Hazardous Air Pollutant Analyst
