Compliance Report: Complies The screen skip is fully enclosed, emissions from the skip are ventilated to the odour scrubber for biological removal. 5 The consent holder shall ensure that: a. Sludges and/or bio-solids produced from the treatment facility are aerobically digested prior to air-drying. b. Anaerobic drying of sludges and/or bio-solids does not occur at the site. Compliance Report: Complies Automatic DO readings are taken from probes housed within the digester to ensure conditions are suitable for aerobic digestion. In addition to this, anual readings are taken Monday, Wednesday and Friday using a portable probe, this information is recorded on a check sheet in the office. The dairy check sheet for the day I visited showed an average DO reading of 2.02mg/l across the four cells. 6 Drying of bio-solids and sludges shall be restricted to air-drying processes only. Compliance Report: Complies Bio-solids and sludges are air dried in a large glass house. Once dry these solids are carted to the West Coast for disposal, according to Daryl the solids were carted twice in the past year, this is likely to occur again in September/November when ground conditions in the receiving location are more conducive to spreading. 7 Records of complaints relating to the sewage treatment and disposal operations shall be maintained, and shall include: a.
