Experience Highlights

  • Advised an automotive client on permitting aspects for new low volume hybrid supercar manufacturing facility utilizing non-traditional manufacturing technologies. In addition to permitting aspects, the project required negotiating state implementation plans revisions to address differences in rules designed for high volume coating technologies.
  • Represented automotive manufacturer in appeal of state regulatory agency’s effort to mandate permitting for full-vehicle dynamometer operations as stationary sources. Favorable decision resulted in revision of Ohio rules and exemption of full vehicle dynamometers at automotive manufacturing facilities from stationary source permitting.
  • Development of Ohio’s first Clean Air Act Plant-Wide Applicability Limit (PAL) permit allowing for increased flexibility for an automotive manufacturer to rapidly respond to changing market conditions without burdensome permit modifications.
  • Extensive Experience coordinating environmental audits of automotive manufacturing and parts facilities, and developing strategies to respond to audit findings.
