EPA. etc. This discharge is located on the Neuse River mainstem. An analysis on the river indicated that more stringent controls on BOD loading are needed. Therefore, an engineering report evaluating the cost feasibility of meeting advanced tertiary limits (i.e., 5 mg/I BOD5 and 2 mg/1 NH3-N) is due on April 1, 1997. If the facility cannot technologically meet these limits, the engineering report should include an evalutaion of alternatives to discharge. The facility is operating well under the permitted flow of 0.5 MGD. An ATC was issued in 1985 for a total capacity of 0.125 MGD. The facility has built to 0.125 MGD. The permit will be reissued with at a wasteflow of 0.125 MGD at existing limits. At any wasteflow greater than 0.125 MGD, the effluent limits will be BOD5=5 mg/I and NH3-N = 2 mg/l.
