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 100t6 of each Ph:336.367.7941 Fax:336.367.4205 boonvillenc.com Nlapor: Vaughn Benton; Commissioners: William Paul Bairy, 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. If you have any questions, please do not hesitate to contact me at ieff.iones@boonvillenc.com or my cell 336.466.0887. Thank you for your time, j Director / ORC r _� ROy:COOPER Governor MICKNE4.5.

During the inspection, WSRO staff noted several continued violations of NOV- 2019-OV-0003, as well as additional new violations. Copies of the follow-up inspection reports are included for your records. While onsite, the following additional violations were noted by WSRO staff and,may be included in any future enforcement action against,your facility: New Violations 1. Review of the October through December 2019 DMRs revealed several data collection/recordation errors forthe flow parameter. Corrective action: Immediately begin an in-depth examination of all flow data and the collection and calculation methods used to ascertain daily flow values to determine the extent and cause of the errors and then develop and implement corrective procedures to rectify the cause(s). Continued Violations/Additional Observations:. 1 2. None of the currently designated six backup operators work at the facility. There is therefore no backup operator properly designated as required by the permit. i y°I r b75rD Corrective action: Immediately designate at least one properly certified backup operator for the plant. 3. The second treatment train, which floated out of the ground about 2'to 3 years ago when it was drained to facilitate maintenance and resurfacing, has still not been reset and placed back in service. 10"Department ofEnvirmunental Ne:!

Data collection, reporting, and maintenance appears to have improved somewhat with the assistance the Town has received from the DWR Laboratory certification unit However, during this inspection Mr. Boone noted several erroneous flow meter readings on the DMRs from October thru December 2019. The erroneous data appears to be either calculation or transcription errors. This is a vioilation. The ORC reported to Mr. Boone during this inspection that the effluent sampler is still not pulling the required amount of sample for each aliquot. The ORC stated the sampler still pulls about twice as much sample as needed for each aliquot. The ORC indicated he just has not been able to get it fixed yet. Given the fact that this was also a violation noted during the August 2019 inspection, this is a continuing vioilation. The plant description lists a comminutor but there isn't one installed. The plant description should be updated to correct this mistake. The Division will not reopen a permit to update one minor errant component in the plant description, but the Town should make sure this change is made during the next permit rewrite. As was also noted during the August 2019 inspection, none of the currently assigned six backup operators work at the plant. Mr. Jones stated that Mr. Steve Hutchins is his backup operator but he is not so designated in DWR's database. Therefore the plant does NOT have a designated backup operator. This constitutes a continuing violation. It was noted during the August 2019 inspection that the overflow weir on the first treatment train's clarifier is not level and the scum skimmer arm appears ineffective, or minimally effective. The ORC stated during this inspection that nothing has been done to address these issues as of yet, which constitutes a continuing violation. This plant consists of three individual treatment trains; one circular (100K GPD), and two rectangular (50K GPD,each). One of the rectangular units floated approximately 2 to 3 years ago when it was emptied to facilitate maintenance and resurfacing. Unfortunately, the unit has not been reset and placed back in service yet, in part due to difficulties the town has experienced with the first contractor that was hired to do the work. A new contractor has now been hired. This is a continuing violation. Many components throughout the treatment process are old and quite dilapidated, and possibly as a result, ineffective, or partially so. For example the clarifier's skimmer on treatment train #1, appears minimally effective, but it's effect on the plant's overall effectiveness is unknown. As such the skimmer should be repaired to attain its maximum effectiveness as it was intended when first installed. Otherwise the unit should be removed from the treatment process, following the procedures and protocol established by DWR in approving NPDES permits. Facility dependability is questionable at this point Page# Permit: NCO020931 Inspection Date: 03/05/2020 Owner -Facility: BoonvillevwvTP Inspection Type: Compliance Evaluation Record Keeping Are records'kept and.maintained as required by the permit?

However, review of the October thru December 2019 DMRs during this inspection revealed several errors on the data collection and recordation of flow. This process should be reviewed and refined to prevent such flow reporting errors. This is a violation. Also, none of the six currently designated backup operators work at the facility. There is currently no backup operator officially designated, as was also noted during the August 2019 inspection This is a continuing violation.
