I have included in this package the clarifications and other documents that were requested. The City of Lenoir currently has 3 major sources: Lower Creek WWTP sludge, Gunpowder Creek WWTP sludge, and Lake Rhodhiss WTP sludge which are all introduced into the sludge holding tank and mixed before being dewatered and sent to the landfill. We are requesting that the Town of Blowing Rock be added as a resource. I am resubmitting the RSC form and other documentation as requested. The Town of Blowing Rock will not be required to submit a VAR as the sludge is hauled to Lower Creek Biosolids facility in a 4,000 gallon tanker truck owned and operated by the Town of Blowing Rock to be introduced directly into the sludge holding basin and mixed with all the other sludges for de -watering and drying. Construction is due to be completed by December 2020 on the new gas dryer system that will dry the sludge to 90% which will meet the pathogen reduction requirements of fecal coliform density, the time/temperature requirement and Vector Attraction Reduction requirement by drying of stabilized residuals for the final product.

The City of Lenoir owns a 7,000 gallons tanker truck and the Town of Blowing Rock owns a 4,000 gallon tanker. Respective City of Lenoir and Blowing Rock employee will haul the sludge from those facilities to the Lower Creek WWTP Biosolids treatment facility, where it is introduced directly into the sludge holding tank. All the sludges introduced into the holding tank will be mixed and aerated before being pumped to the belt press for further processing. 2. Operation of the Program. Sludge, from the Sludge Holding Tank is thickened by the belt press before being fed into the Thermal Belt Dryer. The proposed dryer will produce over 90% solids and provide biosolids particles in excess of 1769 F for pathogen reduction. The system will also dry un-stabilized solids to over 90% for vector attraction reduction. Gryphon is able to verify Class A biosolids compliance by 1) monitoring of process temperatures, moisture contents, and cycle times, 2) drying the solids to over 90% solids, and 3) verifying fecal coliform levels by lab analysis. The percent solids content must be measured at least once per day at the following locations: feed sludge to belt press; thickened sludge from belt press; and the final dried product. The daily flow of feed sludge must be documented (calculated from the sludge meter readings). All of the above listed activities are performed by the biosolids treatment operator. 3. Maintenance Schedule. The sludge flow meters are calibrated by a third - party on an annual basis. The Public Utilities maintenance staff will be responsible for maintaining the hydraulics of the belt press, the electrical operations of the system, and major overall system operations including malfunctions. The Condenser Filter for the Thermal Belt Dryer is swapped, cleaned, and inspected daily by Public Utilities Staff. The Cooling Tower and Condenser Coil for the Thermal Belt Dryer are flushed monthly. The Injection Plate and Externals of the Cooling Tower for the Thermal Belt Dryer are cleaned/washed on a monthly basis. 4. Safety Measures. Biosolids treatment operators and maintenance staff must comply with PPE requirements. This includes the use of disposable latex or nitrile gloves, heavy duty water proof gloves, when appropriate, and face masks in the Class A production area. Signage is provided within the Residuals Building indicating areas that require hearing protection and areas designated as confined spaces. Upon inspection of the application site, the City spreader truck driver should ensure that there are no dangerous slopes to traverse, as the truck is top-heavy when loaded. 5. Spill Response. All spills in the biosolids treatment and storage area are routed to floor drains, which go to the influent of the WWTP. There are no bulk liquid hazardous chemicals used in the process. All sludge from parking lot and Class A area is routed back to the plant influent. If a spill were to occur from the spreader truck in transit to the application site, the driver must stop as soon as it is discovered. The superintendent of WWTP must be notified immediately with the following information: Elisa Triplett: Superintendent Wastewater Treatment Telephone: 828-757-2198 Email: Irtriplett@CI.LENOIR.NC.US It may be necessary to notify city police, sheriff's department, or highway patrol, so that traffic can be controlled while cleanup is taking place. If needed, additional personnel will be dispatched to assist in the cleanup. As much product as possible should be shoveled up and put back into the spreader truck; remaining solids should be swept up. Prior to leaving the biosolids storage area, any biosolids overspill on the spreader truck should be swept as clean as possible. 6. Inspection Plan. The following personnel are responsible for inspections of the biosolids treatment system prior to operation (before each shift): a. Jonathan Whisnant, Biosolids Operator b. Jake Soots, Biosolids Operator Daily inspections of the Belt Filter Press include verifying that that the wash system is properly operating, ensuring proper belt tracking, inspecting the belt for excessive wear and inspecting the equipment of foreign debris such as plastic and inorganic materials. Daily Inspections of the Thermal Belt Dryer include the following: Conveyor Belt —tracking ii. Conveyor Belt — binding and wear iii. Leveler Section — brush iv. Heater Functionality— pressure and flow v. Chamber Temperatures vi. Condenser Coil Inspection vii. Sifter Assembly -Brush and Screen — binding and wear viii. Dryer Chamber — spray wash functionality ix. Cooling Tower — water temp and water supply If it is found that the system cannot be run in compliance, safely or efficiently, the system must not be operated unless the problems are corrected. If problems are found, the personnel listed above must contact one of the following: c. Elisa Triplett, Superintendent Wastewater Treatment d. Donnie Hawkins, ORC e. Tommy Mann, Superintendent Public Utilities Maintenance Application site inspections are the responsibility of the actual land applier, hauler, or spreader truck driver. When biosolids are actually applied by the City driver, the driver will have to make sure that all permit requirements are met, including buffer zones for application. The current driver with those responsibilities is: f. Jerry Denny If it is found that the biosolids application procedures cannot meet compliance, safely or efficiently, biosolids cannot be land applied until the problems are corrected. If problems are found, the personnel listed above must contact either of the following: g. Elisa Triplett, Superintendent Wastewater Treatment h. Tommy Mann, Superintendent Public Utilities Maintenance A copy of this plan, as well as a copy of the Utilization Agreement will be kept inside the spreader truck. The Utilization Agreement will be given directly to self -haulers. 7. Sampling and Monitoring Plan. Sampling of the final product is conducted in accordance with the residuals permit. The sampling frequency is once per quarter for metals, nutrients, fecal coliform bacteria, pH, and percent solids. The exact parameters are listed in the permit. Actual frequency is based on the amount of final product applied to the land. A TCLP analysis on the final product is conducted annually typically during the winter months. The laboratory / pretreatment staff are responsible for the sample collection and transport to the contracted lab(s). The individual responsible for sample collection is: a. Matthew Mackie, Pretreatment Assistant. Below is a description of sampling procedures: b. For TCLP, metals, nutrients, and total solids, the storage pile is sampled in at least ten (10) different locations. The samples are mixed to make a "composited" sample, from which the final sample taken to the lab is taken. At least two (2) bags are collected along with two more for any analyses sent to another lab besides the regular contract lab (currently arsenic, lead, and selenium are being sent to Statesville Analytical, Statesville, NC; all other parameters and TCLP are being sent to Blue Ridge Labs, Lenoir, NC). • For Fecal Coliform sampling, seven (7) samples are collected from different areas of the pile and placed in separate bags. The seven samples are transported so that they can be analyzed within 24 hours. 1) SAR Na Ca Mg 7320 10000 3460 43.7736 59.8 20.6908 milli eq 1.9032 2.99 1.724233 SAR = 1.9032 1.53529 DT/day SAR = 1.239635 Year 1 Year 2 Year 3 Year 4 Year 5 Total 2) IPAN surface = 98279.9 mg/Kg 196.5598 PAN injection = 133179.9 mg/kg 266.3598 Surface TKN PAN PAN Remaining organic nitr (mg/Kg) (mg/Kg) (mg/Kg) (lbs/DT) 281000 98279.9 196.5598 182720.1 182720.1 27408.02 54.81603 155312.1 155312.1 11648.41 23.29681 143663.7 143663.7 5387.388 10.77478 138276.3 138276.3 1 2592.68 1 5.1853611 135683.6 145316.41 290.6328 mg/Kg mg/L I bs/to n I bs/to n ogen mEq = (mg X valence) _ molar mass Percent solids = 1 0.598 Ammonia - nitrogen Mineralization rate NO2-NO3-N TKN = 69800 mg/Kg 0.3 19.9 mg/Kg = 281000 Injection TKN PAN PAN Remaining organic nitrogen (mg/Kg) (mg/Kg) (mg/Kg) (lbs/DT) 281000 133179.9 266.3598 147820.1 147820.1 22173.02 44.34603 125647.1 125647.1 9423.531 18.84706 116223.6 116223.6 4358.383 8.716767 111865.2 111865.2 2097.472 4.194944 109767.7 E:::::] 171232.3 342.4646 ao a0a-0 ('T �t r� t�P- (()qRESEARCH N� Ti A 3Report of Analysis Y:� J I.Abommii , INS. 9/9J2020 For: Water Tech Lads, Inc.
