A state audit has called out Delaware County's (N.Y.) fleet management practices, focusing its harshest critique on the county's lack of oversight of personal use and vehicle disposal practices.

The audit, which was released May 6, came from state Comptroller Thomas DiNapoli, who evaluated the fleet's management practices from Jan. 1, 2013 to Aug. 15, 2014. The county maintains a fleet of 250 vehicles at a cost of $2.8 million.

The county doesn't maintain a consistent practice for assigning a vehicle to an employee and where it should be kept after business hours, the audit reported. A review of 26 vehicles logs from June to July 2014 showed that 19 vehicles were used for commuting purposes. The vehicles were driven for 53,000 miles, of which 22,100 (or 42 percent) were for commuting.

Seven of the 19 vehicles disposed of during the audit period didn't have proper Board of Supervisors authorization, and 17 were sold or scrapped without determining whether another method could have netted more revenue.
