Pem-dts & Engineering Comments:
This is a permit renewal for a discharge of 0.006MCD of domestic wastewater. Within the past
eighteen months this facility had violations of Bod5, Tss, ammonia, fecal,total phosphorus and total
nitrogen. Downstream fecal values seem quite high. The Gates County Schools is currently constructing
an artificial wetland system for Buckland Elementary. The permittee must submit as built plans for
this new facility. Permits and Engineering will recommend existing tertiary limitations with
monitoring reflecting current regulations for a class 11 facility. No renewal application received at this
time. Region needs to advise the permitte6 concerning permit renewal.
