This inspection was conducted to verify that the facility is operating in compliance with the conditions and limitations specified in NDPES WW Permit No. NC0059200. Based on the on-site visit, the facility was determined to be in compliance. The following additional item was noted during the inspection:  Safety: The ORC currently manually feeds chemical into a tank on top of the facilities control building. This is a potential fall hazard. Recommend finding a more permanent solution to the inoperable CIP pump to remove the potential hazard. Please refer to the enclosed inspection report for additional observations and recommendations. Your assistance and the assistance of Mr. Mike Beck during the inspection was greatly appreciated. If you have any questions, please do not hesitate to contact me at 828-296-4686 or by email at mikal.willmer@ncdenr.gov.

This inspection was conducted to verify the facility is being operated and maintained in compliance with NPDES Permit No. NC0059200. Mike Beck, ORC, and Freddie Boan, POA Manager, were present and assisted in the inspection. The facility was upgraded to an MBR system in January of 2016. Mr. Beck and Mr. Boan report permit limit compliance issues arose recently due to several equipment failures. The ORC discovered a whole in the MBR lines and replaced with more durable piping. Additionally, two of the three blowers installed during the upgrade are currently inoperable. Trillium staff have installed two additional blowers on site in case of any additional equipment failures. Several of the submersible pumps within the basins were pulled and replaced with air lift pumps due to repeated impeller failure. The ORC and Trillium staff maintain a supply of impellers onsite for the submersible pumps that could not be replaced. The CIP feed pump is inoperable. The ORC currently accesses a tank on top of the main building to feed chemical by hand. While this is only done every six months, it still poses a safety hazard for the ORC. Recommend a more permanent solution be explored to remove the potential safety hazard. The ORC believes the repairs and equipment replacements will help improve effluent numbers moving forward. The most recent repair was completed on May 3, 2018. NC0059200 17 (Cont.)
