A copy of the current NPDES permit was kept on site. Laboratory data was reviewed and all data that was reviewed appeared to be correct, as reported on the DMR's. It was mentioned during the inspection that there is currently no certified ORC designated for this facility, only a designated Backup ORC. Also, the sample storage units were not maintaining the proper temperature for sample storage; This needs to be addressed.
