Inspection Summary:
Mikal Willmer and Tim Heim, with the Asheville Regional Office, conducted a compliance evaluation of the City of Lenoir’s
DCAR program in conjunction with the City’s NPDES inspections on February 8, 2022. This inspection was conducted to
assess the status of the new solids processing equipment, sampling areas and current hauling records for the facility. The
analytical data will be reviewed in depth when the 2021 Annual Residuals Report is received.
Approximately 30 loads were distributed in 2021. The City will provide bulk distribution in addition to allowing customers to
haul their own residuals. The %TS is >90% and facility staff report local farmers like the granularity of the product for
spreading on their fields. Staff indicate they can process approximately 4 dry tons of solids a day with the thermal belt dyer
on the current operating schedule. If needed, the dryer could be run more than one shift and/or more than three times a
week. Overall staff are happy with the dryer; however, the auger design reduces the volume that can be fed at one time.
There is currently a hopper immediately downstream of the belt-press. The hopper’s capacity to convey cake from the belt
press is restricted by the size of the auger feeding the belt dryer.
City staff showed inspectors an exterior residuals hopper that could theoretically receive pressed residuals from other
sources. Staff indicated the conveyance system does not work and they currently have no plans of utilizing the exterior
hopper. As a reminder, should the City wish to accept additional residuals at this location a modification of the DCAR
permit would be required to add a new residuals source.
Sampling: Temperature is measured as residuals exit the dryer using the thermal belt dryers built in thermometer. It is
recommended staff verify the accuracy of this thermometer at least annually. %TS is collected and composited from the
end of the thermal belt dryer once a shift.
The treated residuals are kept underroof in a new three-sided storage shed. Any residual runoff from hauling and
transporting solids from the shed drains to the head of the plant.
