Page# NPDES yr/mo/day Inspection Type (Cont.) 31 NCO089656 I11 121 20/03/06 117 18 JCJ Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) On March 6, 2020, MRO staff met with the permittee and their consulting firm to perform a routine Compliance Inspection. During the site visit, O&M records, eDMR records, and flow data were reviewed. The flow from the facility is well below the permitted daily flow for the permit. There is a sump pump in the garage and a float system associated with the sump pump. The pump floats were not able to be checked due to their position in the sump. However, during a high-water circumstance, the SCADA system alerts the building maintenance crew of the high-water circumstance so they can respond. The building maintenance crew also performs physical checks during the around the clock to verify the systems are not in an alarm condition. The treatment system also has a wet well associated with the system. The float and alarms associated with the wet well were able to be checked and the audio and visual alarms activated during the test. The effluent discharge was viewed at the effluent sampling port. No odor, color, foam or solids were observed at the effluent sampling port. During the site visit, the outfall was also viewed. However, with the low flow from the facility, flow from the outfall was not able to be viewed. A sampling port is also located at the mid -point between the two carbon vessels. Samples are collected from this port to test for break -through in the treatment vessel. The activated carbon vessels are located in the parking garage area, spent carbon and replacement carbon have to transfer new and spent carbon through a pumping truck and hose system. A separate tanker needs to be present to place new carbon into the vessel once the spent carbon has been removed. After the transfer,the vessel with the new carbon becomes the polishing vessel. The permit is currently permitted for a flow of 108,000 GPD. The average flow from the facility is approximately 25,000 GPD. Most of the water from the facility is captured and used in the building HVAC system. Ultimately, the receiving stream does not receive much flow from the treatment system. Page# Permit: NCO089656 Owner - Facility: Dimensional Place Inspection Date: 03/06/2020 Inspection Type: Compliance Evaluation Operations & Maintenance Yes No NA NE Is the plant generally clean with acceptable housekeeping? 0 ❑ ❑ ❑ Does the facility analyze process control parameters, for ex: MLSS, MCRT, Settleable ❑ 0 ❑ ❑ Solids, pH, DO, Sludge Judge, and other that are applicable? Comment: Housekeeping at the site was good. During the site visit, it was suggested that the activated carbon manifests and the calibration records be kept as part of the facility O&M records so they can be tracked. The O&M records were able to be viewed electronically. Therefore, these records were considered to be onsite on the date of the site visit. The MRO has received a copy of the invoice for the flow meter as Droof of calibration. It is estimated that carbon for the vessels are changed on a 6-month basis. Permit Yes No NA NE (If the present permit expires in 6 months or less). Has the permittee submitted a new 0 ❑ ❑ ❑ application? Is the facility as described in the permit? 0 ❑ ❑ ❑ # Are there any special conditions for the permit? ❑ 0 ❑ ❑ Is access to the plant site restricted to the general public? 0 ❑ ❑ ❑ Is the inspector granted access to all areas for inspection? 0 ❑ ❑ ❑ Comment: The permittee has an electronic copy of the permit. The permit is current and present during the inspection. The current permit is scheduled to expire on June 30, 2020. A permit renewal application has been submitted to CO. Compliance Schedules Yes No NA NE Is there a compliance schedule for this facility? 0 ❑ ❑ ❑ Is the facility compliant with the permit and conditions for the review period? 0 ❑ ❑ ❑ Comment: Mid -point sampling is used to determine when break -through has occurred and when the polishing vessel needs to be swicthed to become the treatment vessel. The facility is current with Acute Toxicity sampling. All eDMR reports are current and complete. The facilityis in compliance with permit compliance schedules. Page# 3
