There is currently no monitoring required for this permitted discharge. The effluent limits for the discharge have been developed such that the waste treatment system should protect the water quality. Although this is a permit reissuance, the facility has not yet been constructed. Following construction, twelve grab samples shall be collected within 180 days and analyzed for Biochemical Oxygen Demand (5-Day). The results shall be submitted in a written report to this office within 28 days after the twelfth sample is taken. The results will be reviewed by the Permit Board, and the permit may be reopened and modified accordingly. This permit is also subject to modification if future evidence, monitoring results, or nuisance conditions indicate a higher degree of treatment is required to maintain water quality in the receiving stream.
