Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
On May 8, 2018, Linda Wiggs (DWR Inspector) conducted a follow up inspection to observe the
de -chlorination system SGL Carbon installed to meet the Total Residual Chlorine Effluent Limit
Requirement. At the time of the inspection the de -chlorination system appeared to be functioning
effectively. However, there was an issue with the de -chlorination system in March; a NOV
(NOV-2018-LM-0044) was sent on May 15, 2018.
This was also a joint Stormwater inspection with DEMLR staff; Isaiah Reed (DEMLR ARO), Bethany
Georgoulias and Rick Riddle (DEMLR Central Office). SGL staff present for the inspection were Jim
Smith and Lee Gjetley. SGL Laboratory staff, Jeff Woodruff, was present during the lab visit. A joint
inspection with DEMLR staff was beneficial since wastewater (permit NC0005258) and stormwater
(permit NCS000009) comingle. DEMLR staff are working on the renewal of the stormwater permit.
Sampling:
Since the wastewater and stormwater are comingled, sampling for each permit needs to be
representative. SGL staff need to make reasonable efforts to sample their wastewater when it is not
raining.
