NCG510500 111 121 18/07/31 1 17 18 ICI Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) During the site visit, it was discovered that the treatment system had been turned off by by directive of the UST Trust Fund in August 2017 and re -started in March of 2018. No notification was provided to MRO-DWR that the system was being taken out of service. Conditons for general permit Section E Reporting Requirements states that the DWR- MRO is to be notified within 24 hours of system shut off or failure. Failure to report similar incidence in the future may result in the issuance of a Notice of Violation(NOV). Other than the notification, the system was reviewed and found to be in compliance with the permit. A new flow meter was installed on July 2, 2018. A copy of the receipt of purchase has been provided to the MRO and will be used as proof of meter calibration. Waste manifests for spent carbon was also recieved by the MRO. The system is permitted to discharge up to 50,000 gallons per day(GPD)of treated effluent. However, the average dailty output for this system is about 239 GPD.

Comment: Operation and maintenance lops were reviewed during the site visit. Durina the site visit. both recovery wells were reviewed. The reauested correction to lower the riser pipem has been made to RW -5 to to prevent the top of the well from hitting the gallery cover. Also, bolsters were placed around RW -5 to prevent additional damage from occuring to the well gallery box. This seems to have help to protect the well as no additional damage appeared to be present. However, it was suggested that high visibility paint be applied to the bolsters to make the RW more visible. The air stripper was serviced during system shut -down. Surge tank floats were replaced this past June 2018.
