The department’s officials couldn’t provide its inspector general (IG) with data about its land purchase programs, the watchdog’s report said. The IG consequently surveyed 108 programs and found that just 16 of those awarded 701 grants between 2014 and 2015 to purchase $815 million worth of land. DOI “does not centrally track information about grants awarded for the purpose of acquiring land,” the IG 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. The “number of grants and land value could be substantially higher than what we were able to determine through our survey,” the report said.
