Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
RECORD KEEPING SECTION cont'd:
A review of the facility's self -monitoring data during the on -site inspection revealed the following:
- Effluent total residual chlorine (TRC) values were being reported below the meter's lowest verified
standard (20 ug/L);
- All ORC and/or Backup ORC visitations were not properly documented in the May 2018 eDMR;
- The units of measurement for effluent dissolved oxygen was not properly designated on the eDMR
(should be mg/L instead of "Calculated").
The facility staff must ensure that all monitoring data and on -site visitations are properly documented
on future eDMRs.
