NDA CULPEPPER, Infuun Dewar Mr. David Robinette, Public Works Director 67 Main Avenue Drive Taylorsville North Carolina 28681 Dear Mr. Robinette: NORTH CAROLINA Empfronraental Quarrry November 27, 2018 Subject: Compliance Inspection Report Permit No. WQ0006906 Land Application of Residuals Town of Taylorsville Alexander County The MRO would like to extend its appreciation for the time and assistance provided by Mr. Brian Eades during the November 21, 2018, inspection. Enclosed you will find the report for the compliance inspection. The new digester and residuals loading area have addressed previous loading area concerns expressed in the last inspection report. Residuals application occurred during the inspection event. The MRO would also like to extend its appreciation to Mr. David Key for his assistance at the application field. Both the residuals process and application appear to be in compliance with the permit. The report should be self-explanatory. Should you have any questions regarding this report, feel free to contact Edward Watson at edward.watson(a)ncdner.gov, or 704-235-2198. Sincerely, DocuSigned by: F161FB69A2D84A3... Andrew H.

However, due to the excessive amount of precipitation experienced this past year, application windows have been limited. Permit condition 111.3. requires notification to be provided to the MRO prior to conducting land application events. In order to avoid compliance issues, please be sure MRO is provided the required notification prior to all LA events. The new digester has significantly reduced the potential for the residual material from entering the near site creek. Also, the capture drain and the sloping of the drain installed at the new loading area provide a means for capture that was not present previously. The old loading area still exists. If it becomes necessary for the old loading area to be utilized during future application events, please be sure to place spill protection in the old loading area to prevent residuals from entering the creek.

SSFA (Standard Soil Fertility Analysis)? ❑ ❑ ❑ Are PAN balances being maintained? ❑ ❑ ❑ Are PAN balances within permit limits? ❑ ❑ ❑ Has land application equipment been calibrated? ❑ ❑ ❑ Are there pH records for alkaline stabilization? ❑ ❑ ❑ Are there pH records for the land application site? ❑ ❑ ❑ Are nutrient/crop removal practices in place? ❑ ❑ ❑ Do lab sheets support data reported on Residual Analysis Summary? ❑ ❑ ❑ Are hauling records available? ❑ ❑ ❑ Are hauling records maintained and up-to-date? ❑ ❑ ❑ # Has permittee been free of public complaints in last 12 months? ❑ ❑ ❑ Has application occurred during Seasonal Restriction window? ❑ 0 ❑ ❑ Comment: Monitoring wells are not installed on the individual fields. The TCLP was determined to have been performed based on a review of the metals analysis data presented. Soils analytical data was performed for each field where residuals were applied. It was verfied via email the Carol Price (CP-1) field will need to have a lime ammendment performed to raise the pH level of the soils on this particular field. Pathogen and Vector Attraction Yes No NA NE a.
