The assistance of Stevie Inscoe, Ronald Parker, Bryan Bowen, Dud Frazier, and Amy Ratliff was greatly appreciated. Observations during the inspection are summarized below. An inspection checklist is also attached for your records. 1. The most recently issued permit (January 01, 2015) states that The City of Oxford operates a wastewater collection system consisting of approximately 56 miles of gravity sewer, approximately 1 I miles of force main, and 11 duplex pump stations. The current permit expires on December 31, 2022. A renewal application should be submitted at least 180 days prior to expiration. 2. The collection system is classified as a CS-2. A review of the Division's database BI.MS (Basinwide Information Management System) lists Steve Inscoe as Operator to be in Responsible Charge (ORC). Bryan Bowen and Ronal Parker are both listed as backup ORC- 3. Reported Sanitary Sewer Overflows (SSO), Since the last compliance inspection conducted by DWR (June 29,2017), there have been two reportable SSOs from the collection system. The estimated volume was less than 200 gallons, with only approximately 25 gallons reaching surface waters. 4. Records review: The Capital Improvement plan was available and consists of the required information. The City has developed and implements and educational fats, oils and grease program that includes at least bi-annual distribution of educational material. Adequate records are being maintained regarding customer complaints, pump station inspections, high priority and easement inspections. The collection system map is available on G1S. Ensure the map includes flow direction. The following pump stations were inspected: Kingsbury, Coons Creek, Knotts Grove, Willows and Rest area. a.
