NCO050610 I11 12I 20/08/11 117 18 i c i Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) The plant description in the permit needs to be updated. There is no grit chamber or tertiary treatment. Please ensure the plant description is appropriately updated during the next permit renewal. The effluent composite sample is currently being collected from the aerated tank upstream of the UV. The permit requires that the effluent sample be taken downstream of all treatment units. Please reconfigure the sampler to comply with this requirement. The audible alarm did NOT work when the influent pump station's high level float was activated. The ORC found that the audible alarm horn's wires had come loose and the alarm worked correctly after he reattached them securely. The alarms should be checked daily to ensure constant operability. This should be a part of regular operations and maintenance (O&M) that should be documented as such. The pump station also has a telemetry system which was NOT tested during the inspection. It is noteworthy, however, that tripping the high level float to test the audible and visual alarms should have also activated the telemetry system, yet the ORC was not notified during the remainder of the inspection, of any problems at the pump station. The ORC was unsure who the system contacted in the event of an alarm condition. He said he thought it contacted Jadd Brewer, who would in turn, likely contact him. This system should be well known by the ORC and all backups. The telemetry system should also be tested regularly to ensure it operates properly. This should be documented as part of the regular O&M. The EQ basin connects directly to the digester via a 4" metallic pipe. If the level of the EQ ever reaches that height the wastewater flows directly to the digester. Once the level of the digester gets to a certain height, it'll then flow into the aeration basin. The EQ basin does NOT have overflow detection systems or alarms. The permittee should consider installing them as another level of protection. The pipe that connects the EQ basin to the digester has a hole in it, caused by corrosion, which should be repaired. The entire plant structure is heavily corroded and if allowed to continue unchecked will result in failure at some point. The corrosion should be corrected and prevented from reoccurring. The plant has three blowers, one of which is inoperable and does NOT have belts installed. The blower should be repaired as soon as possible. The ORC pulled a solids sample from the aeration basin about an hour prior to the inspector's arrrival on site. The ORC uses what appears to be just a one gallon plastic bottle with the top tapered portion cut off. He filled this with sample from the basin and after about one hour approximately the bottom 20 to 30 percent of the container contained solids. The solids content of plant appears acceptable but the operator should be using an actual settleometer to run the test and should be recording the results of the test as part of regular O&M. The plant could use additional maintenance. There is a lot of corrosion and the plant has a lot of uncontrolled solids build-up in the clarifier baffle zones/troughs, overflow weir troughs, etc. The ORC said, and the DMRs reflect, that he only spends about 30 minutes on site 5 days per week. This shows the minimal time invested in the proper O&M of the plant. The clarifier's weirs and overflow trough were quite dirty. Some pin floc was definitely apparent in the overfllow, although the water looked clear. Page# Permit: NCO050610 Inspection Date: 08/11/2020 Owner -Facility: The Ponds WWTP Inspection Type: Compliance Evaluation The tertiary filter does NOT contain actual filter media. It contains plastic plates that the ORC called "bats". These "bats" are placed in the filter tank in series at an angle of about 15 degrees from horizontal. The water does NOT pass through the bats, according to the ORC, but rather just flows around them. The filter is therefore not actually filtering. If anything, it is only baffling the flow of water through the tank. There were solids (pin floc) flowing thru the filter and over the overflow weir of the filter. The chart recorder pen appeared to be out of ink at the time of the inspection... or nearly out. The ORC stated that he would replace it. The flow meter was last calibrated in July, 2020. Spare UV bulbs are kept at Water Quality Labs' main office in Banner Elk. The effluent appeared clear and free of solids but flow was heavy and of very high velocity so it would be very difficult to see any solids unless they were very large or of very high concentration. Overall impression is that not enough time is spent operating and maintaining this plant. Although it appears to consistently meet permit effluent limitations, it is not well maintained. It displays a large amount of superficial and more severe corrosion all over the plant. The plant is NOT very well kept and contains excessive solids (i.e. bar screenings, scum in the clarifier's baffle troughs, etc). It is also a safety hazard as many of the steel grate walkways are missing and/or structurally unsound. As previously stated, the ORC, Brandon Hughes, spends only about 30 minutes per day at the plant. Mr. Hughes stated that he currently operates six differnent plants, all of which are owned by Water Quality Utilities, Inc. He also stated that one of the two owners, Jadd Brewer, who also operates some of their plants, will retire soon, at which point Mr. Hughes will become responsible for three more plants, for a total of nine plants. It's very questionable whether Mr. Hughes will be able to effectively manage the proper O&M of nine different treatment plants. Water Quality Utilities, Inc. currently has one mobile generator staged at its office in Banner Elk. It is currently intended to serve all plants owned/operated by Water Quality Utilities, Inc. It is therefore asserted that the reliability requirements for this type of facility, as stated in 15A NCAC 02H .0124, are NOT being met. The permittee needs to make a serious accurate assessment of whether it has sufficient backup equipment to facilitate continued uninterrupted and unaffected operations at all of its facilities in the event of a catastrophic failure to ensure it meets the intent of the reliability requirements in 15A NCAC 02H .0124.
