® ROUTINE ❑ FOLLOW-UP ❑ COMPLAINT ❑ PERMITTING ❑ Other:
Comments (attach additional pages as necessary)
On site at 10:35 AM. Met with Brent Collins, EMA. Met at the WWTP. Three tankers/tractor trailers
(7,200-gallon tankers - numbers 125, 140, 142). Observed one tanker loading up residuals from the two
1,000,000-gallon concrete digesters. No spillage. No staining of the asphalt or tracking of sludge out
of the WWTP observed. Discussed operations at the WWTP. Left WWTP and travelled out to the
James Albert property at 11:00 AM.
Arrived at application field (NC-RC-005-1). A rain guage was observed inthe field. Inspected the field.
The terrain was slightly hilly with the slopes ranging from 3% to 6%. The solids content in the residuals
was 0.98%. The field was properly flagged. No runoff or ponding of residuals from previous spreading
was observed. Two 4,200 gallon tractor -pulled spreaders were applying residuals. The O&M plan and
the permit were present. The O&M plan was adequate. Each 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. Observed transfer of residuals from tankers to spreaders. No problems.
Left application field at 12:10 PM.
Is a follow-up inspection necessary? ❑ Yes ® No
