EDNR comments "Ammonia samples for 11/22, 11/25-11/27 was poured out by the laboratory analyst. She thought due to being
out for thanksgiving (her normal analysis day) that she didn't have to run the samples. Corrective actions were taken against the
employee and SOPs have been updated accordingly".
