This inspection was performed as a routine maintenance inspection related to DCAR Permit No. WQ0002834. Paul Isenhour, Chad Prisk, and Chris Wilson were present and assisted with the inspection. Aside from necessary recordkeeping protocols, discussed below, the facility appeared to be in compliance from an operational standpoint. Initial Solids Processing: Solids appear to be handled appropriately. Compositing operations are not expected to grow for the foreseeable future. Currently, the facility uses a portion of residuals from the wastewater treatment plant to generate compost. The remainder of the residuals are hauled to the Foothills Landfill. Solids to be composted are transported to the mixing pad where they are mixed with woodchips supplied by French Broad Utility. Static aeration is applied, and the piles are monitored for at least 14 days with the blower set to cycle on and off in 15-20 minute intervals. Compost processi ng: Five spots of each pile are monitored for temperature daily and measurements are recorded on a paper log kept in the main office area. Temperature records indicate that the product met the requirements for Pathogen and Vector Attraction Reduction. Facility representatives indicated they were having no consistent issues with the thermometers used to collect temperatures. Once the compost is ready, it is placed outside, uncovered, on a concrete pad in a 10-12 ft tall pile. Leachate from the composting area is routed back to the headworks of the WWTP. We recommend that staff record the depth of temperatures collected on the paper log. Note that the facility has the option of adding VAR Option 45 (vector attraction reduction method) as a certified parameter on their field lab certification, if desired. For further information, contact the Lab Certification branch. Sampling: Samples of the final product are collected using an excavator bucket. Sampling depths range between 18 inches and 3 feet deep. Fecal coliform samples are collected from seven locations on the same day. The facility is generating approximately one pile of finished compost per year. It is recommended that bacteria samples be collected over a two-week period. Distribution: Compost customers are provided information regarding composting use and information (including setback requirements) upon pickup. Screened compost is provided by request only as running the screen is labor-intensive. Hauling records are kept in the main office area. Recordkeeping: Hauling, sampling, and temperature records appeared to be in order. An electronic copy of the Operations and Maintenance Plan was provided after the inspection. The O&M Plan needs to be updated to include the following information and a hard copy should be stored in the office area. -The following information needs to be included in this plan, per section III.2 of the current permit: Safety Measures, Spill Response Plan, Inspection Plan, and Sampling and Monitoring Plan. -It is recommended that the Sampling and Monitoring plan include sampling locations, depths, and frequency. Note that the plan also needs to include the following specific information (section III.2.f of Permit): -Specifically list out requirements for pathogen and vector attraction reduction as part of the composting operations. This includes updating temperature requirement for pathogen reduction (55 degrees C/131 degrees F or higher for 3 consecutive days) and include fecal coliform values (<1,000 MPN/g for each sample taken). Also include an overview of the process to further reduce pathogens (PFRP) for compost – static aeration where temperature is maintained at 55 degrees C for 3+ days. -Detailed description of monitoring procedures including parameters to be monitored. -Include Vector Attraction Reduction process – 14-day aerobic process where temperatures are greater than 40 degrees C/104 degrees F and an average temperature of 45 degrees C/113 degrees F.
