V. ADDITIONAL REGIONAL STAFF REVIEW ITEMS
This staff report was prepared for the permit renewal of the Town of Faison WWTF, Permit W00003661. Since the
last staff report in 2017, there have been no effluent or spray application violations. Groundwater monitoring in the 5
monitoring wells show compliance except for some low pH values.
The Town has requested to eliminate Field 8 because of the concern for run-off due to steep slopes of the perimeter.
The field was observed to be over grown duringtpection in July because of lack of use over many years. WIRO
does not have any concerns with eliminating this field, because the facility has not had any issues with over irrigation
and the current flow averages approximately 50% of the permitted flow.
The Town has also requested to take down the fence surrounding Lagoon #3. The lagoon is within the fence of
WWTF locked site. WIRO concurs that maintenance around the lagoon is difficult due to the close proximity of the
fence to the lagoon.
Section II.4 of the permit is recommended to be removed since the Town of Faison has an individual collection
system permit, WQCS00172.
