This inspection was conducted to verify that the facility is operating in compliance with the conditions and limitations specified in NPDES WW Permit No. NC0057703. The findings and comments noted during this inspection are provided in the enclosed copy of the inspection report entitled "Compliance Inspection Report". The facility was found compliant. However, there are two issues listed in the CIR that require your attention: 1) Preparation and submittal to this office of a narrative/schedule with the plans for the installation and operation of the plant expansion (second phase for flow > 260,000 gpd) by 07/30/2019. 2) Plans for the implementation of repairs in areas of the plant that are showing an advanced stage of corrosion. If you should have any questions, please do not hesitate to contact Morella Sanchez-King with the Water Quality Regional Operations Section in the Wilmington Regional Office at 910-796-7215 or via email at morella.sanchez-king@ncdenr.gov.

The writer appreciates the support offered by AQUA staff during the inspection and for providing information as soon as it is requested. • Operation and Maintenance: The facility appeared well operated and maintained. However, there are areas that require corrosion repairs due to the age of the plant. Electrical panels have been replaced due to hurricane Florence damages. • Solid Handling: Lewis Farms handles the solids in the facility. • Record Review: ORC log book, DMRs, and sampling/chain of custody records were organized and complete on inspection day. • Parameter Exceedances: The facility has a history of enterococci violations and related civil penalty assessments. DMR records show that the last NOV for enterococci violations was issued in April 2018 since then the facility has been in compliance with this parameter. The facility was issued NOV for TSS violations in December 2018. • Future wastewater treatment capacity (80-90 rule): The facility is reaching 85% of the as-built flow of 260,000 gpd. Please provide an engineering narrative and schedule for installation and operation of the plant's next phase. • Effluent Appearance: On inspection day, the effluent was clear and odorless. Remaining comments are located in the questions section of this report.
