Butler County Auditor Roger Reynolds addresses the media on Feb. 24, 2020 to advocate for House Bill 499 and fuel quality testing. The bipartisan bill, introduced by Reps. George Lang and Brigid Kelly, would allow county auditors the authority to test fuel for octane level, water and sediment. Also pictured are Ross Twp. Trustee Tom Willsey, Reily Twp. Trustee Nick Schwab, Lang and Kelly. Although the bill never received a vote, two more fuel quality bills have been introduced during the current 134th General Assembly - HB 144 and SB 71.
