The department’s officials couldn’t provide its inspector general (IG) with data about its land purchase programs, the watchdog’s report said. “As such, DOI is unable to identify how much grant money has been used to purchase land, how much land has been purchased and whether that land is being used for its intended purpose. Additionally, less than half of the 278 grant recipients reported their land inventories to the DOI programs that funded them, which violated federal regulations, according to the report.
