The purpose was to conduct a compliance inspection. The facility has contracted with EMA Resources Inc, Mocksville, NC, to distribute the Class A residuals and provide technical assistance to assure environmental compliance and to assure they meet the requirements related to performance standards, operation and maintenance responsibilities, and monitoring & reporting. Currently, the plant's treatment residuals are pumped to two 1.5 MG Iagoons where the solids settle and the resulting decant is pumped to the Town of Hillsborough Wastewater Treatment Plant. There are two additional lagoons where thickened residuals can be pumped for drying. Residuals were hauled and distributed at the end of August and the beginning of September to the D. Pope property, site Oro2, fields 1 through 5. Fields were inspected and residuals appeared to have been spread on mowed fields in compliance with permit conditions. Residuals were analyzed for metals, pathogens, TCLP, PAN, SAR rates and found to be within permit limits. Hauling records were reviewed and found to be in compliance. �E �;A -yA North Caro,ina Department of Env1ronmefndl Quality I Division of Water Resources `� Raleigh Reyiorial office 1 3800 Barrett Drive I Raleigh, North Carolina 27009 �/� Please -refer -to the attached inspection report.
