BUTLER — The Butler County board of commissioners took these actions Wednesday:

Ratified the refinancing of a $9.5 million 2019 bond, which was approved Aug. 26. The refinance will drop the county's fixed interest rate from 3.46% to 1.33%, which will save an estimated $772,000. The original bond was used to establish the county infrastructure bank, which used the funds to finance the downtown streetscape and Sullivan Run flood control projects in Butler and the MSA throughway and sewer rehabilitation project in Cranberry Township. Key Government Inc. will refinance the bond.

Approved an agreement with Tanner Bartholow Forensic Pathology Services to perform autopsies and other services for County Coroner William F. Young III. Among the service's charges are $1,150 per autopsy performed in the county, $500 per appearance at a coroner's inquest or magistrate's hearing and $750 per court appearance. While the agreement does not have a termination date, the contract can be terminated by either party with 30 days written notification.

Approved a $100,000 local use fee grant for Winfield Township to assist the township with the paving of Spiker Road and Helmbold Avenue. The project cost was $230,348.

Approved the Area Agency on Aging's request to rent the Starlight Drive-in on Sept. 21 for $650 and a $6 per-person ticket fee to provide a senior movie night for county residents aged 60 and older. The event is to promote the senior centers in Butler County. The cost will not exceed $3,050 and will be paid through state and federal grants. The movies to be shown have not yet been decided.
