rehabilitation/replacement and operation of approximately 1,823 linear feet of 8-inch

MH 31, and between MH 25, MH 31, MH 27, MH 27A, and MH 28, at varying slopes
between 0.22%- 0.31%, as well as approximately 232 linear feet of 15-inch gravity

Regardless of the variance approval, in the event that the wastewater collection facilities fail to
perform satisfactorily, including the creation of nuisance conditions, the Permittee shall take
immediate corrective action, including those as may be required by this Division, such as the
construction of additional or replacement facilities.
