Dear Mr. Scott:
The Division of Environmental Management has completed a review of the "as -built"
plans submitted July 24, 1989, and finds that a permit amendment is not necessary.
The following items were reviewed and found to be acceptable minor changes to the
approved plans for the subject permit.
1. The top elevation and the ground level elevation of the pump station wet well are
now both shown six inches higher.
2. The top rim of the effluent manhole is shown three feet lower, making this manhole
three feet shorter. This should not effect the effluent discharge.
3. The influent box is slightly redesigned and relocated to the other side of the cat
walk, a few feet from where it was. The redesign should not effect the original
function or capacity.
4. The foundation for the tertiary filter is two feet longer, and should provide better
support.
5. The WWTP six inch drain line is now shown running counter clockwise around the
plant to reach the pump station wet well; where before the six inch line was shown
clockwise around the plant to reach the wet well.
