They met with Bobby Poarch, the ORC for the WRF. The ORC was able to provide all records requested and explain how the system is supposed to operate under normal conditions. Facility is not operating under normal conditions as many of the diffuser heads are broken and are scheduled to be fixed in the middle of October. After reviewing the records and the system, it was determined that this facility is out of compliance as their permit expired on July 31, 2022, and no renewal application has been received at this time. Please contact the Wilmington Regional Office with your plans to renew the permit or rescend the permit.
