Reason for Inspection: Routine Inspection Type: Compliance Evaluation Permit Inspection Type: Wastewater Irrigation Facility Status: ❑ Compliant Not Compliant Question Areas: Treatment Flow Measurement -Effluent Treatment Flow Measurement -Influent Miscellaneous Questions Treatment Flow Measurement -Water Treatment Record Keeping Use Records Treatment Lagoons End Use -Irrigation Treatment Disinfection Treatment Flow Measurement (See attachment summary) Page 1 of 7 DocuSign Envelope ID: 91`1792AB-BEC6-428D-92BC-12A74546FB4F Permit: WQ0002571 Owner - Facility: Bobby F Williams Inspection Date: 07/11/2023 Inspection Type: Compliance Evaluation Reason for Visit: Routine Inspection Summary: A routine inspection of the Village Oaks Mobile Home Park WWTF was conducted on July 11, 2023. The purpose of the evaluation was to verify that the facility is operating in compliance with the conditions and limitations specified in Permit WQ0002571. Lee Buck, ORC, was present during the inspection. This facility is a 786,522 gallon facultative lagoon system with a hydraulically connected 332,486 gallon storage lagoon and 3.6 acre spray irrigation field. It serves the Village Oaks Mobile Home Park and was originally permitted in 1985. The spray area appears to be in much better condition than the last inspection in January 2020. A review of monitoring reports show no violations. The west, east and north edges of the spray area slopes down considerably and irrigation needs to continue to operate so no run-off occurs during spray events. The facility was found to be non -compliant for the following issues: 1. There was some erosion of the east side of the facultative lagoon causing a low point along the berm. The water level gauge needs to be surveyed again to this lowest part of the lagoon. Currently, the freeboard appears to be 1 foot from the lowest point. 2. Documentation of maintenance for the irrigation equipment and field were not available. 3. Flow calibration records of the irrigation equipment, since the last inspection, were not available. 4. The BORC listed for the facility has an invalid certification. A Notice of Violation will be issued. Please see the comment sections of the inspection report for more details.
