Mr. Collins stated that a record of field inspections is not available, but all fields are inspected and flagged with courtesy and required buffers prior to application activities. Moving forward, please keep a log of all field inspections prior to the commencement of land application activities. 188 dry tons/year is permitted with no intention of increasing or decreasing this amount. Residuals are produced from the sediment basin and filters. Liquid residuals are land applied at agronomic rates. Based on the residuals analysis results provided for 1/24/2022, the residuals contain 4.78 Ibs PAN/ton. Two concrete storage basins (275,000 gallons each) are used for storage, with at least 365 days of storage. Residuals were last hauled at the end of the previous calendar year. Residuals are likely to be hauled again during the next budget year. Ms. Caudle requested that the field summary form be provided for this last application event as application fields are included in the Davie County Class B permit. Mr. Collins stated that all bulk residuals are land applied on fields included in permits managed by EMA because of existing landowner agreements to accept residuals. If bulk residuals are applied to fields not included in a permit a utilization agreement will be signed. Ms. Caudle requested that she be notified during the next application event to review application activities.
