Spoke to Buck 9/30/15 to confirm if sampling was representative, he said he would look into it. Spoke again 10/15/15, Buck believed sample was not representative so I requesting supporting information. Spoke again 11/10/15 to confirm sample was representative so letter was sent to system this date outlining steps that must be taken as a result.
