PURPOSE OF THE INSPECTION
A U.S. Environmental Protection Agency (USEPA) program review inspection was conducted in the City of Roanoke Water Utility offices located at 245 Marshall Creek Road, Roanoke, Texas 76062. The inspection was conducted under the guidelines established by the USEPA under the National Pollutant Discharge Elimination System (NPDES) for wastewater collection systems. The purpose of this inspection was to inspect and review the City of Roanoke's current Sanitary Sewer Overflow (SSO) response protocols and their application of a Capacity, Management, Operations and Maintenance (CMOM) program and how the program is used to insure proper operation and maintenance of their collection system. An entry briefing was conducted by EPA-Region 6 inspectors David Long, Damon McElroy, and Jeanne Eckhart at 9:00a.m. on April6, 2017 at the City of Roanoke Wastewater Utilities offices. The inspectors met with Jayson Allbright, Public Works Depmtment Crew Leader and Robby Wallace, Public Works Depmtment Equipment. During the entry briefing, the EPA inspectors provided credentials and explained the purpose of the inspection, as well as set the timeline for the day and verified the availability of documents that had been requested the week before.
At the conclusion of the inspection, an exit briefing was conducted that explained the suggestions and areas of concerns noted during the inspection that are detailed in this repmt. This repmt is based on information supplied by the City representatives, observations made by the U.S. EPA inspectors, records and reports maintained by the City, the State of Texas and the USEPA.
PROGRAM DESCRIPTION
The City of Roanoke is approximately 5.3 square miles in size and includes a population of 6000 residents (approximately 2200 residential connections and 285 commercial connections) which are provided wastewater services through approximately 60 miles of sewer lines. Over 99 percent of the collection system has been updated since 2000 with PVC pipe. The remaining collection system is composed of vitrified clay. The wastewater collection system has six (6) lift stations and sewer pipes ranging in size from four to 54 inches in diameter. However, the city does not have a Supervisory Control and Data Acquisition (SCADA) system, nor cell based call out system on any of the lift stations. Each lift station does have onsite audible and visible alarms in case of overflow and each station is checked daily (seven days/week) to ensure proper operation during the day. Any issues occurring after regular business hours will be routed from the city switchboard to the on-call wastewater operator for investigation and repair. Only one lift station has a dedicated emergency generator in the event of an electric grid failure. However, the remaining lift stations can be hardwired for electric power supplied by portable generators. The City of Roanoke collection system has experienced only one SSO since 2014. Known problem areas of the collection system, where SSOs have occurred in the past are placed on a quatterly preventative maintenance schedule and cleaned to eliminate/reduce overflows. In addition, Roanoke budgets approximately $50,000 per year to repair and maintain their collection system. Further, Roanoke does have a CCTV van to check collection system integrity in both public and privately owned sewer lines.
