PART IV - EVALUATION AND RECOMMENDATIONS
On January 25, Mitch Hayes of the Division of Water Office conducted a site visit at the
Roxboro Water Treatment Plant. The wastewater treatment system consists of one holding
lagoon which is used as a holding pond for alum sludge, one drying bed, one concrete
filtration tank with discharge pipe. There are also one holding pond and one drying bed
that are not in use. There were no indications of any overflows from the holding ponds. All
banks were solid with no signs of animal holes or erosion. The valve controlling the
effluent discharge is kept slightly opened. Effluent consists of filter backwash water that is
chlorinated before being discharged into a UT to Marlowe Creek. The effluent was clear
and had no noticeable negative impact upon the stream. The Water Treatment is currently
meeting all permit requirements. The pH requirement for the discharge to be between pH
6 and pH 9 was left off the last issued permit and should be reinstated. The Raleigh
Regional Office recommends that the permit NCO003042 be renewed in accordance with
the Roanoke River Basin Wide Plan.
