On May 1, 2013, Ohio EPA published notice of proposed revisions to its Best Available Technology (BAT) program. Under Ohio’s air pollution control law, owners or operators applying for air pollution permits for new or modified sources are required to provide their recommendations for BAT to minimize air emissions from the source. Ohio EPA’s proposed revisions would impact two of the four case-by-case options for BAT determinations – the Work Practices option and the Source Design Characteristics or Design Efficiency of Applicable Air Contaminant Control Devices option – and would be implemented through modifications to OAC 3745-31-05 and Ohio EPA’s BAT Requirements for Permit Applications Filed On or After August 3, 2009 guidance document.

Comments are due by May 31, 2013.
