Inspection Summary:
A routine compliance inspection of the Queens Grant WWTF was conducted on June 27, 2023. The purpose of the
evaluation was to verify that the facility is operating in compliance with the conditions and limitations specified in Permit
WQ0028785. Darrell Covington, ORC, was present during the inspection.
This 35,400 GPD wastewater treatment plant is a subsurface system consisting of 3 septic tanks and 4 Envirofilter tanks,
along with a NxClear unit for denitrification and suspended solids removal. Disposal includes a 20,160 GPD high -rate
infiltration system and a 15,240 GPD subsurface disposal system, Permit 487039, issued and monitored by the Pender
County Health Department. The facility is currently using both disposal options.
The installation of the Siemens Simatic HMI controller system has allowed effective operations and monitoring of the plant
on -site as well as remotely. The facility has a consultant for the system that works with the operator when needed. Lewis
Farms is contracted to remove the top scum layer of the septic tanks yearly and the solids every other year.
The facility operator designations need to be updated for both wastewater and spray irrigation certfication types, as well as
owner affiliation. Please use the Change of Name/Ownership form and the Operator Designation form found on
www.deq.nc.gov under Water Resources Division. The facility needs a field lab certification for pH reporting. To apply for
certification, please use the same website information above for instructions.
The facility is compliant with the Non -Discharge Permit WQ0028785. Please review the comment sections of the inspection
report for more details.

Comment: The facility has a NxClear unit consisting of 2 sand filter cells for denitrification and suspended
solids removal. 25% Methanol is infected based on flow, and every 2 hours the cell is "bumped"
to release nitrogen gas. The cells are air scoured and backwashed once a day to the mudwell
which is pumped back to the influent pump station. During the summer months, when flows are
higher, both cells are in operation and in the winter months the cells are alternated. The
composite sample is taken at the NxClear effluent, before UV treatment. The sampler was in
good condition with clean tubing.
