Inspection Summary:
On 10/24/2019, MRO staff observed a Land Application Event for permit WQ0006906, Taylorsville WWTP.
The fields where sludge was applied had proper signage present.
The WWTP was inspected. During the WWTP inspection,the operator log book, lime stabilization records and the digestor
were reviewed.
The camera system installed during the upgrade allows the operator to view the digestor operations and the residuals
hauling from the plant office. A knife valve has been added at the request of the LA contractor to reduce the burden on the
truck drivers. The system can be operated by one person rather than by two people.
The loading area was clean. No sludge was observed on the ground at the loading area. There is a drain at the loading area
to capture any overflow that may occur. The drain returns the sludge to the head of the plant.
The LA site was inspected and residuals applied was viewed at the Phillip Henderson Farm. The buffers were properly
marked -out and the field was in good condition.The transfer area at the application field was in good condition. No sludge
was present on the ground at the transfer area. The field was well maintained by Southern Soil Builders.
Residuals were applied to fields:
NC-AL-08-04 Shannon 13.1 acres
NC-AL-CH-01&02 Clyde Henderson 32.7 acres
NC-AL-CP-01 Carol Price 7.0 acres
NC-AL-PH-01 Phillip Hoover 14.7 acres
Both the WWTP and the LA event were in compliance with the permit.

Comment: The permit was on -site and able to be reviewed. Lime stabilization occurred on 9/26/2019.
At
the time of the lime stabilization, the pH was above 12. On the application date was pH still
above12. The ability to maintain a high pH indicates lime stabilization was effective for pathogen
reduction.
Monitoring wells are not required for this site.

Comment: Three trucks were used to haul sludge to the application fields. All of the trucks had spill plans

Comment: The application field was dry and there was good separation between the surface and the top of
groundwater. A rain gauge was present onsite.
No ponding of the residuals was observed and the fields were buffered within the requirements
of the permit.
Terracing on the site made the LA event more laborious as the application truck had to make
multiple maneuvers to apply the sludge onto the field.
The only WSW near the application field was buffered at greater than 100 feet from the well.
