This was part of an original process and is obsolete in terms of our current operation. During the course of Sundays work, staff and I considered the source first to be the new force main from the Influent Pump Station. We shut down that part of the system, Including plugging pipe that fed the Splitter Tower to avoid siphoning backflow. Unfortunately, the spill continued. We then arranged sandbags and gravel to form a barrier to allow the spill to flow into the open manhole, thus minimizing the amount of wastewater to flow elsewhere. The area around the spill was excavated and the flow appeared to be coming from the old pipe. Upon reviewing drawings, we discovered the pipe to be connected to the effluent line that ran from the first stage to the second stage. We discovered a valve at that connection which we then closed and stopped the spill. This valve will remain closed and the pipe will either be repaired or that part of the system preferably effectively abandoned. Initial observations suggested that the spill only reached the edge of the woods beyond the fence. Upon further Inspection however, we found sludge had filled a drainage swale and some areas of marsh that reached the east prong of Slocum Creek. Members of DEQ were present to provide oversight and advice on further cleanup procedures and scope. The City contracted with an environmental abatement firm which, since January 20tn pumped the preponderance of the sludge and settled waste back to the head of the plant for processing and also raked, shoveled and bagged material from the woods which are being deposited at the plant's drying bed. This matter will drain out to a pump that feeds Into our processing system and the dried vegetation etc. will be hauled out in accordance to our normal waste removal procedures. At this time the affected area Is well restored Including removal of a large pile of effluent that settled at the mouth of the drainage Swale. Sampling in 3 locations (at the site and upstream and downstream) started on Wednesday, Page 1 of 2 January 181h and will continue every Monday, Wednesday and Friday until directed otherwise by DEQ to ensure proper monitoring of the condition of the creek. In addition to the line repair, the City will undertake a study of the plant to ensure any areas of potential failure or obsolete functions are addressed and eliminated. We are also initiating a plan for a possible low berm, or dike, around 3 sides of the plant that would prohibit any future spills from reaching surface waters. This design would Include the ability to relieve stormwater build up as well as float warning system with a pump to remove any buildup of wastewater should a spill occur. The City of Havelock Is committed to maintaining not only compliance with State regulations but to the improvement of the environment and the safety of all who access the local waters. We appreciate the State's consideration in our efforts and along with the partnership with DEQ. Please feel free to call with any further questions and I appreciate your understanding regarding this matter. We ask that you consider imposing no, or at least a minimal, civil penalty in this case as the causes were less a result of negligence on the part of the City and more a result of unfortunate mechanical failures. The City, its staff and contractor responded quickly and have performed diligently and effectively to restore the safe and clean condition of the surrounding area. We continue to monitor the site to ensure no additional SSO events occur within our control.
