The purpose of the evaluation was to verify that the facility is operating in compliance with the conditions and limitations specified in Non -Discharge Permit WQ0013027. Dan Fortin and Robert Howard of Fortin Contract Service were present during the inspection. This facility is a 40,000 GPD extended aeration plant with two rotary distributor, high -rate infiltration disposal fields. During 2021, flows peaked to a little over 4,000 GPD in the summer and had very low flows during the winter months. Due to mostly seasonal residential occupancy and the flow from a Septic Tank Effluent Pumping (STEP) collection system, the plant treats an influent high in TKN. This issue has caused many effluent exceedances in Total Nitrogen during this permit cycle. After a review of GW-59 monitoring reports, there appears to be no evidence of groundwater quality standard violations for Nitrogen in the three monitoring wells on site. Since requesting technical assistance from Tom Tharrington of the Wilmington Regional Office (WIRO) in 2019, operators have raised the level and increased aeration and mixing time in the EQ tank as recommended, which improved treatment. In 2021, Mag meters in the EQ tank and common tank disabled flow control and Total Nitrogen was exceeded for many months. Covid related issues with suppplies delayed repairs. Since Jauary 2022, all repairs have been made and TKN has been trending down. The current permit expired on March 31, 2022. The new property management company, Chalk and Gibbs, has been in contact with the WIRO for guidance on the renewal process. The renewal application was uploaded on April 13, 2022. Please note for future reference that the permit requires the submittal of a renewal application no later than six months prior to expiration. The facility is compliant with Non -Discharge Permit WQ0013027. Please review the comment sections of the inspection report for more details.
