Joedavid Hall (ORC — Environmental Inc.) was present and assisted with the inspection. The facility appeared in compliance with Permit NC0068152 at the time of the inspection. The ORC reported that the measures proposed to reduce or eliminate the hydraulic surge which was discussed in the 2018 Technical Assistance Inspection (TA) as the likely cause of the movement of solids into the clarifier and over the weirs were effective in eliminating this problem. These included reducing the blower power and adding diffuser socks to the ends of the pipes where air is injected into the aeration basin. The facility has completed numerous upgrades and repairs following the Compliance Inspection and Technical Assistance reviews with ARO staff in 2018, including: New plate steel and corrosion resistant paint to 3 feet below the hydraulic grade line. Structural steel reinforcement of the basins walls and other components. Rehabilitation of the secondary clarifier. Replacement of the piping and appurtenances associated with the sludge return and waste to digester. New headworks. New walkway grating. Replacement of blower motor. New diffuser heads in the aeration basin. The following items should be addressed to improve operation and safety of the facility: Improve the means of storing and disposing rags removed from the bar screen to avoid creating nuisance conditions. Remove the 2x4 framing that was previously used to suspend tarps during the rehabilitation work.
