He confirmed that the Town of Hillsborough has a significant amount of water treatment <br /> 7 capacity remaining and a significant supply of raw water remaining in its system. He said the <br /> 8 sewer treatment plant capacity is constrained by a lot of permitting limits, and the town was also <br /> 9 driven by some regulatory thresholds they are required to meet in addition to being part of the <br /> 10 Falls Lake rules. He shared that the town is fine-tuning its final water system model and will <br /> 11 present that to the Town of Hillsborough Board of Commissioners with some CIP <br /> 12 recommendations later this year. Connecting this topic back to the joint portion of the evening, <br /> 13 Bryant Green said that a lot of fire districts in the county rely on the town's water system to provide <br /> 14 adequate fire flow protection, and they are always mindful of that when doing hydraulic modeling <br /> 15 in the water system. He said his goal is to make sure the town is a good steward of both water <br /> 16 quality and fire flow availability so that they can remain a good partner in the community. He <br /> 17 explained that one of the driving factors behind the town's technical desire to reduce the urban <br /> 18 service boundary is the desire to provide the best quality and quantity of water to as many people <br /> 19 as possible, and the town plans to achieve that by serving a smaller area that has a higher level <br /> 20 of density. <br /> 21 Commissioner Portie-Ascott asked if the regulatory constraints are federal requirements. <br /> 22 Bryant Green said the regulatory constraints in question are part of the town's NPDES <br /> 23 (National Pollutant Discharge Elimination System) permit that is issued by the state. The state <br /> 24 dictates how many pounds of nitrogen and phosphorus the town can discharge into the Eno River <br /> 25 each year, and there is a cap to that number. Given the current Falls Lake rules and pending Falls <br /> 26 Lake rules, he explained it is unlikely the town would get additional discharge into that reservoir <br /> 27 and has been a good steward of the poundage allocated so far. <br /> 28 Commissioner Carter said she is the representative on the Neuse River Basic Association <br /> 29 board, and there is a lot of discussion happening on the Falls Lake rules. She said it seems they <br /> 30 are in flux and is not clear if they will become more or less strict right now. <br />
