Compliance history was reviewed from September 2019 through August 2020. No permit limit violations were reported during review period. At time of inspection treatment facility appeared to be well operated and maintained. Effluent was clear with no visible suspended solids. Construction of plant upgrades were ongoing at time of inspection. Four (4) aeration blowers and related piping and controls are to be replaced under A to C #065684A04. No excessive odors were noted around WWTP at time of inspection. This Office has received several complaints in the past regarding odor comming from Country Wood WWTP. The site was visited, as result of complaints, on April 23, 2018 and a Compliance Evaluation Inspection (CEI) was conducted on May 23, 2018. During both site visits no unusually strong or offensive odors were noted. Aeration basins had earthy smell and EQ basin had light ammonia smell that disipated 20-30 feet away from basin.
