Removal of the discharge will be required if a more environmentally sound alternative is available. An engineering report evaluating alternatives to discharge is due 180 days prior to permit expiration along with the permit renewal application. As part of the report, the cost of constructing a treatment facility to meet limits of 5 mg/1 BOD5, 2 mg/1 NH3-N, 6 mg/1 DO, and 17 µg/1 chlorine must also be included if there are no alternatives to a surface discharge. Upon review of the results of the engineering report, the Division may reopen and modify this NPDES permit to require removal of the discharge, modified treatment designs, and/or revised effluent limitations within a specified time specified time schedule. The facility has had no toxicity failures and no violations within the past year. There are no other dischargers within the immediate area. Instream data indicate that DO's have been less than 5 mg/1 both up and downstream. There are no SIU's to Macclesfield WWTP.
