Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
Tim Heim of the Asheville Regional Office performed a Compliance Evaluation Inspection on June 4,
2018. Wes Royal (ORC) was present at the time of the inspection. The facility appeared to be well
maintained and operated and in compliance with Permit NC0052043.
The discharge pipe in the receiving stream was not accessed during the inspection due to very steep
and vegetated terrain, however effluent observed leaving the dechlor chamber was clear and free of
solids.
All dischargers to the collection system have septic tanks, so the system receives very low solids.
The ORC noted that he was currently having trouble finding a pumper truck to access the site to
remove solids from the digester and clarifier due to extremely steep terrain. He will notify ARO if he is
not able to resolve this. Several potential solutions to this problem were discussed.
It was noted that the permittee may want to upgrade to a 25-50 Kgallon system at some point in the
future. This will require a major modification and several options and ideas were discussed.
