Page# 1 31 NPDES yr/mo/day NC0086517 111 121 22/05/11 117 Inspection Type 18 [j (Cont.) 1 Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) On May 11, 2022, staff from the DWR-MRO performed a Compliance Evaluation Inspection under permit NC0086517. The facility uses some of the treated water for the building HVAC system. A majority of the water from the system is discharged through a UT to Irwin Creek. As part of the site visit, MRO staff became more familiar with the system that collects water from the treatment system used for the HVAC system. The water in the HVAC system remains in a closed loop. No water -related to the treatment system is used for irrigation around the building. The wet well was able to be viewed during the site visit. The well is located outside of the HVAC system area near the garage exit. There is an unassociated vehicle detailing operation in the building basement. During the site visit, it was noticed that some of the chemicals used in the car detailing operation are being stored in a 55-gallon drum. The drum is next to the system GW well and sump. There should not be any chemicals stored next to or in the vicinity of the well and sump. Accidental discharge of the cleaning chemicals has the potential to become introduced into the well and sump and create additional chemical impairment. The MRO is requesting that there be no chemicals or cleaning solutions stored near the well and sump associated with the GW treatment system.
