Grants Funds (municipals only)?
2. Special monitoring requests:
3. Additional effluent limits requests:
4. 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.
