MLSS did not have a smooth roll and was devoid of fine bubbles. Oxygen transfer appeared to be ineffective and wasting energy. Diffusers should be repaired or replaced. Sludge Handling Disposal Hole rusted in bulkhead between aeration basin and waste sludge tank. Aerobic Digester Top of bulkhead between digester and aeration basin has rusted out and bulkhead may collapse if digester is pumped all the way down. The rusted -out hole in bulkhead makes it ineffective to waste and dewater sludge at this facility. In addition, the issues below must also be addressed: Compliance Issue(s): Please be advised that in accordance with NCAC T15A: 02H .0211, Permit Renewals, permit renewal should be submitted at least 180 days prior to expiration.

Page# NPDES yr/mo/day Inspection Type NCO070289 I11 121 18/01/22 117 18 JCJ Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) As of date of this inspection the Division has not received a renewal permit application. Diffusers in aeration basin require repair or replacement. Sludge waste tank requires repair of replacement. Although at the time of inspection the ORC was doing an exceedingly good job of operating the subject wastewater treatment plant (WWTP). The above noted plant deficiencies will hamper plant performance and the ability of operator to effectively and efficiently operate WWTP at peak performance.
