The purpose of the evaluation was to verify that the facility is operating in compliance with the conditions and limitations specified in Permit WQ0000795. Zack Butler, ORC, was present during the inspection. The Town operates a 1.5 MG Sequencing Batch Reactor treatment system and irrigates on fields 1-16 at the Sarge Martin site at the plant location and fields A-H at the Juniper Swamp site, approximately seven miles west on Hwy 50. Flow is limited by a disposal of 1,100,000 gallons monthly average and 767,800 gallons annual average. There have been some irrigation exceedances on the Juniper Swamp fields in the past year. The Town has been working with the Wilmington Regional Office and continues to evaluate the expansion of more disposal options. A review of files from the last two years shows no effluent parameter exceedances and the parameters tested are well below the effluent limits. The modifications listed in the current permit are under construction. Some beams and grating at the headworks has been replaced. Piping to connect the new disc filter and a 12 inch valve between the post EQ and the disc filters were completed recently. All of the modifications are expected to be completed in approximately one year. The facility is compliant with Non -Discharge Permit WQ0000795. Please review the comment sections of the inspection report for more details.
