Town of Valdese
Routine
Inspection Summary:
Melanie Kemp, with the Asheville Regional Office, conducted a review of the Town of Valdese’ s 2022 DCAR Annual Report
on May 15, 2023. This review was conducted to determine whether the facility processed and monitored all residuals in
compliance with Permit No. WQ0001990.
The Town distributed approximately 700 dry tons of Class A Compost to customers in 2022. Please resume submitting the
dry tons calculation worksheet and/ or include the conversion on the customer distribution sheet.
Pathogen Reduction (PR) is met via fecal coliform density reduction below 1,000 MPN/g and through PFRP Option E:
composting. The static aerated piles appeared to exceed 55°C for at least three consecutive days. The Town is currently
collecting one fecal sample and a duplicate every quarter. All reported results are less than 1,000 MPN/g. It is
recommended multiple fecal samples are collected over a two-week period to obtain a better representation of the residual
quality.
Vector Attraction Reduction (VAR): VAR is met via the 14-day aerobic process (Option 5). All constructed piles appeared to
exceed 40°C for at least 14 consecutive days and had an average temperature that exceeded 45°C.
Metals, Nutrients & Pollutants of Concern: Values were below the monthly and ceiling concentration limits for Class A
products. All metals and nutrient parameters were analyzed per section IV.3 of the permit. PAN & SAR balances are being
calculated and maintained quarterly. SAR values for 2022 were below 10. Metals and Nutrients under section IV.3 will be
required on the source residuals before the end of the permit cycle.
Non-Hazardous Waste Characterization: Please note that the non- hazardous waste characterization was removed from the
permit as of 10/14/2022.
The following issues were noted with the report:
-Total volume (dry tons) distributed to recipients is missing from form DMSDF.
-All supplemental lab reports are missing.
-On form RSSF, please include the MQL value (i.e. <0.05 vs *) for results that are below lab limits.
-The fecal coliform results provided on form PVRF 02T do not match the bench sheets. Minimum is 6, geometric mean is 42,
and maximum is 185.
