V. ADDITIONAL REGIONAL STAFF REVIEW ITEMS
Reconnaissance inspection performed by Helen Perez and Jordan Cocanower as part of the staff report for a requested
ownership name change. Lee Buck,the current ORC of the facility,was onsite to assist with the inspection.Also
present was Ashley Sheets,representing the new ownership of the facility.
Overall,the facility seems to be running as intended. Mr. Buck noted that the facility is receiving flows well
under its permitted allotment which coincided with Ms. Sheets statement that the current occupancy of the trailer park
is at just above 50%.
The area surrounding the lagoons had been recently mowed and no odors were present, indicating aerobic
treatment activity within the lagoon. The primary lagoon is experiencing localized berm erosion,with an obvious low
spot in the berm at the northeast corner of the lagoon. The freeboard was found to be adequate at the time of the visit.
The spray irrigation fields were in good shape,with adequate cover found throughout most of the field. The fields
were dry at the time of the visit.No evidence of prior channelization or standing water was visible in the fields
visited.Mr. Buck estimated he has been irrigating twice weekly. Mr. Buck stated that he has not had trouble keeping
the lagoons at a reasonable level,though he believes the lagoons to be very shallow in part due to the settled solids
that have accumulated.
The recent response to the NOV issued August 29th,2023,was revisited during the visit. It was confirmed that
the water level gauge was resurveyed,the flow meter was calibrated, and maintenance logs had been utilized. The
facility is actively searching for a BORC as the predetermined BORC has failed to gain the necessary credentials for
operating the plant.
Discussions were had with Ms. Sheets regarding her parry's obligations as it relates to the non-discharge permit.
Ms. Sheets indicated a desire for facility upgrades and a future maintenance plan that included berm stabilization,
additional signage, and a backup pump as well as finding a backup operator for the facility.Also discussed was the
necessity to provide the department with the renewal application,which has not been received at this time. Ms. Sheets
stated that after the name change is approved and she receives signature authority, a renewal application will be sent.
Overall,the aquisition of the Village Oaks Trailer Park by Ms. Sheets parry seems to be beneficial for the treatment
facility as a whole and will help to ensure future compliance through increased funding and a desire to maintain
existing infrastructure.
