Mr. Key and David Key, US Biosolids, were present during the review of the application fields. Application was not occurring during the time of inspection. This review reflected compliance with the subject permit. An email was sent on September 22, 2022, requesting the following information by October 3rd: • YVSA TCLP • YVSA 30 day bench test • Field inspection forms for the application event This information was received on October 3, 2022.

Other observations: • Residuals were being hauled from the Yadkin Valle Sewer Authority WWTP. • Influent ❑ Bar Screen ❑ Grit Chamber ❑ Oxidation Ditch (has an anoxic zone) ❑ Clarifiers (2) ❑ CCC OR Sludge Thickening Basin ❑ Sludge Holding Tanks • Two 200,000 gallon storage tanks store residuals. The tanks are open to the atmosphere and have aeration. The tanks have 3-4 months of storage. • A composite grab is used for all sample parameters. • Nutrient and metals were sampled on 3/15/2022. • Fecal samples were collected on 3/3/2022. • PAN was calculated to be 28.186 Ibs PAN/dry ton. • The trucks are top loaded on a paved parking lot. • 28 loads have been hauled so far.
