ORC visitation logs and calibration records appeared to be complete and current. Temperature measuring devices and flow meters are being calibrated annually, as required. Laboratory data was reviewed. All data that was reviewed appeared to be correct as reported on the DMR's. Since the previous inspection, a permanent repair has been made to the failing wall separating the influent chamber and effluent chamber. When this work was performed, all treatment units were completely cleaned out. This facility has no total residual chlorine limit, so no dechlorination is required. Pilkington performed some maintenance work adjacent to the treatment plant and removed a signifcant amount of soil from around the treatment works, it is recommended that the soil be replaced to insure there is no impact to the integrity of the treatment unit walls, as well as possible personnel safety reasons. The effluent was very clear and appeared to be free of any visible solids.
