Department of Environmental Quality Received APR 0 3 2020 Winston-Salem Regional Office Town of Boonville PO Box 326 110 N. Carolina Avenue Boonville, North Carolina 27011 On behave of the Town of Boonville, I am writing a response to the Letter we received from your office dated March 17, 2020. Currently the Town of Boonville uses Mission Communication for our monitoring. We have only used it for High flow alarms along with power outages. Since we have had some miss calculations with our flow data, I have contacted Mission to see if we could add a totalizer. Mission is going to add a totalizer so I will receive it with my daily report. With this in place, we will have a back to double check our calculation. Us not having a backup ORC on record is an over sight. About 18 months ago, the Town sent Steve Hutchens to Waste treatment operator class. When he received his operator certification, he filled out the forms to be assigned to our backup ORC list. We assumed that is was documented with the State of North Carolina. Since this was brought to our attention, we found out he was not listed and since, we have resubmitted his paperwork to the State of North Carolina and faxed a copy to the Winston Salem Regional office. Town of Boonville received a SRF loan in 2017 for our waste treatment plant upgrades. During the construction, Plant #2 floated out of the ground. After the floating of Plant #2, the town board fired the engineer, Municipal Engineering, and hired WithersRavenal to finish the project. We also had an Attorney looking into litigation. Since January 2020, the contractor has been on site working to finish the plan set in place by WithersRavenal. The most current schedule is for the project to be completed by the end of April 2020. During Ron's first visit, we found out that our Effluent sampler was over sampling. Since his last visit, we worked on getting it calibrated and found that the hose was cut the wrong length. We replaced the hose to the right length, which got us very close (120ml = 150ml), but not 100% right. I contacted Eric with Clearwater about our problem. When he got on site, we started looking over the sampler to find that the liquid detector was not enabled. Once we turned that on, we ran 6 samples to find it 100% accurate. During the beginning of Construction, Plant #1 floated also, but nowhere near as bad as Plant #2. At the time, we put Plant #1 back into service the weirs of Plant #1 and Plant #2 were with in 100th of each Ph:336.367.7941 Fax:336.367.4205 boonvillenc.com Mayor: Vaughn Benton: Cointuissioners: William Paul Baity, Monica Craver, Richard Lasky, Justin Phillips, Tony Reece other. I assume that over the last couple of years the tank has settled a little more, which has gotten the weir level off. By the end of April, our plan is to have the weirs leveled up. I talked with our engineer about the rake arms on Plant #1, and what a possible means to address the efficiency seen by our inspector. After our discussion, the plant was designed to have the arms clear from the center to the skimmer box that is positioned on the other edge of the clarifier. The engineer did recommend that we replace the rubber flaps on the arms themselves. We should be able to do all that work at the same time we are making the changes to the weirs.
