October 21, 2019 Mr. Rick Bolich, L.G., Assistant Supervisor Water Quality Regional Operations Raleigh Regional Office 1628 Mail Service Center Raleigh, NC 27699-1628 Re: Notice of Violation Chapel Ridge WWTP, Wake County Permit No. WQ0022870 NOV-2019-PC-0633 Dear Mr. Bolich: J?,Ilcigh Regional Office Aqua North Carolina, Inc. (Aqua) offers the following response to the above -referenced Notice of Violation (NOV): A ua' s Response: The NOV references a wastewater residual dewatering facility. Aqua does not operate a residual dewatering facility at this location. Violation I — a. I. PERFORMANCE STANDARDS — It states, "creation of nuisance conditions due to improper operation and maintenance, or failure of the utilization areas to adequately assimilate the reclaimed water". The inspection does not indicate any improper operation and maintenance nor the failure of the utilization area to assimilate the reclaimed water. As such, there is no violation of this permit condition and the Notice of Violation should be rescinded. b. With respect to odor, we believe the odor is due to effluent age in the spray irrigation force main. Aqua has previously offered to inject sodium hypochlorite into the force main to stop anaerobic biological activity (which causes malodors) and the ORC Brian Peters with Century Golf, refused on behalf of the golf course and HOA. It is worth noting that Aqua's contract responsibilities ends at the irrigation pond. Aqua is prohibited from installing infrastructure on the irrigation facilities without the owner's approval.Aqua is currently discussing options for calcium nitrate feed (i.e. Bioxide) with Evoqua and pending positive test results and Century Golfs approval, Aqua will submit an Authorization to Construct for a Calcium Nitrate feed system at the pump station. We may request approval for a pilot test of the material prior to design completion. 202 MacKenan Court, Cary, NC 27511 • 919.467.8712 • AquaAmerica.com Page Two Mr. Rick Bolich October 21, 2019 3.
