Other: The design capacity is 0.012 MGD PART IV - EVALUATION AND RECOMMENDATIONS Jerry Whittum of the WSRO inspected this plant on May 26, 1989. The recommendations made by Jerry were in place at this school. The aeration chamber was cleaned out on September 15, 1989. As a result, the sludge was very young and the aeration chamber was dark grey in color. Charles Jefferies, Assistant Superintendent of Physical Affairs, said that the area is growing and the population at this school is expected to increase substantially in the next few years. Since the flow is between 0.004 - 0.005 MGD, it is recommended that the permit be re -issued with the design capacity of 0.012 MGD. The treatment plant has been operating within the limits. 6�IZ9 - &�� ignature of report preparer Water Quality Superv' or
