Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) The treatment system is experiencing issues with elevated Copper. The MRO has issued Notices of Violations in January 2024 and June 2023 for this condition. The permittee is due to reply to the recently issued NOV-NOI letter by the 25th of June, 2024. During the site visit, it was communicated that an email reponse is acceptable to address the NOV-NOI. During the site visit, a review of the eDMR records from January 2023 through May 2024 revealed inconsistencies in the way the laboratory is reporting limits for Copper on the eDMR. Although the eDMR are reporting the elevated values for Copper, the lab reporting is not consistant with the permit limits. Please contact the laboratory to have inconsistencies being reported on the eDMR corrected. Most of the treatment system is composed of inert materials that should not leach copper into the effluent water. During the site visit the possibility of copper entering the treatment system from a green area was discussed. Additional filtration will be added to the treatment system before water from the green area enters the treatment system. Part of the treatment includes a zeolite filter. There is a slight possibility that the copper may be accumulating in the zeolite filter chamber and being released from the zeolite. During the site visit, it was mentioned that the zeolite filter material has not been changed in several years. The permittee may want to collect a sample after the zeolite filter to verify that copper is not being released from the zeolite filter. The wet well prior to the outfall was viewed as part of the review of the outfall. The effluent water entering the well was clear: no foam, color, solids, or odor were present.
