Synagro is the permittee and West Stanly WWTP the source. Inspection included the facility storage/loading areas, active application at field NC -ST -03-07 and a recent application at field NC -ST -03-01. Y -yes N -no NE -not evaluated NA -not applicable Y Permit on site during application Y Spill plan on site Y Buffers adequate Y Cover crop specified in permit Y Site condition adequate N Documented exceedances of PAN limits N Signs of runoff / ponding Y Rain gauge on site during application Y Signage posted Y Current Analytical data for PVAR, Metals, TCLP Are there any limiting slopes on fields? NA 10 % for surface application NA 18% for subsurface application Odors present: No odors were detected. Vectors present: No vectors were detected. Flying insects present appeared unrelated to the residuals activity. Complete permits (except for maps), Operation and Maintenance and Spill plans were viewed in one of the transport vehicles during loading. Two additional transport vehicles were not examined. 451D_K�QP� North Carolina Department of Environmental Quality I Division of Water Resources Mooresville Regional Office 1 610 East Center Avenue, Suite 301 I Mooresville, North Carolina 28115 704.663.1699 Complete application with maps, O&M & Spill plans were present in the technician's vehicle and the spreader vehicle. Field site NC -ST -03-07 was viewed for active application. Only a portion of the field was to be land applied, as the remaining facility residuals volume was insufficient coverage for the whole field. Flagging was placed for sufficient guidance on the portion of the field receiving application. The equipment appeared well maintained and distributed liquid application evenly with no signs of drift, odors or vectors at the time of inspection. Field site NC -ST -03-01 was also viewed for recent application the previous week. Residuals management at the facility and the field site(s) appeared to meet program requirements at the time of inspection. This inspection does NOT cover additional facilities or sources included in this regional permit. The MRO would like to thank Adam Brigman (Synagro) and Don Zufall (WWTP ORC), for their time during the inspection. Please contact Maria Schutte, by phone (704-235-2184) or email (maria.schutte(a)ncdenr.gov) with questions. Sincerely, DocuSigned by: 11111F I, A14CC681AF27425... W.

This inspection only included the West Stanly WWTP and field sites NC -ST -03-07 (active application) and NC -ST -03-01 (recent application). It does NOT cover facilities or residuals from additional sources included under this regional permit. Field site NC -ST -03-07 was viewed for active application. The liquid application appeared to be distributed evenly with no signs of drift, odors or vectors at the time of inspection. Complete permits (except for maps), O&M and spill plans were viewed in one of the transport vehicles during loading. Two additional transport vehicles were not examined. The complete application with maps, O&M & spill plans were present in the techncian's vehicle and the spreader vehicle, at the time of inspection.

Onlv a portion of the field was to be LA, as the remaining facility residuals volume was insufficient coverage for the whole field. Flagging was placed for sufficient guidance on the field portion applied only. The equipment appeared to distribute liquid application evenly with no signs of drift, odors or vectors at the time of inspection. Soil types and water levels are examined when fields are permitted, but not typically re-examined during a LA event. Field site NC -ST -03-01 was also viewed for recent application the previous week.
