04/13/2022 Annual Report Review
Town of Valdese
Routine
Inspection Summary:
Mikal Willmer, with the Asheville Regional Office, conducted a review of the Town of Valdese’s 2021 DCAR Annual Report on
April 13, 2022. This review was conducted to determine whether the facility processed and monitored all residuals in
compliance with Permit No. WQ0001990.
The Town distributed approximately 678 dry tons of Class A Compost to customers in 2021. Please resume submitting the
dry tons calculation worksheet and/or include the conversion on the customer distribution sheet.
Pathogen Reduction (PR): 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’s
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 2021 are 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: The non-hazardous waste characterization is required once per permit cycle for the
source residuals and compost. Corrosivity, ignitibility and reactivity were analyzed quarterly for the compost. As a reminder,
TCLP, corrosivity, ignitibility and reactivity are required for the source residuals before the end of the permit cycle in 2024.
