Comments (attach additional pages as necessary)
Arrived at Eden VWVTP at 1:00 PM. Ryan Copeland, Synagro was at the facility. Discussed operations at the WWTP. The residuals were
pumped from the aeration basin to a Clean Bee Wastewater Treatment System. After treatment the resdivals are stored in a tank. The
residuals are then pmped up a hill to a tank at the the Synagro filter press. After the resudals are run through the press they are moved to a
residuals stroage area adjacent to the filter press. The area has a concrete floor and walls and is covered with a metal roof. Left VVWTP at
1:40 PM. Arrived at 2:15 PM. Inspected the field. The terrain was slightly hilly with slopes ranging from 3% to 6%. The solids content in the
residuals was 20.5%.
The field was properly flagged. No runoff or ponding of residuals from spreading was observed. One truck (15 cubic yard spreader) was
applying residuals. The O&M plan and the permit were present. The plan was adequate. The truck had an O&M plan and maps. The residual
spreading was good. No additional run off or ponding was observed. Proper buffers were maintained.
Left application field at 3:05 PM.
Is a follow-up inspection necessary? ❑ Yes ® No
