To Whom It May Concern, NC-X( 0160}
The City of Morganton is(re)applying for a NPDES Permit(NC006194).This Permit is active through 02/28/25.The
permit is active but there is no discharge flow from the outfall(001).The outfall allows for discharge from the
facility's dewatering and backwashing procedures.The outfall has not discharged flow in numerous permitting
periods.The outfall was previously used to release flow from the facility's decant tanks and belt press building.
The Catawba River WTP is a conventional Class A Surface Water Treatment Facility.The Catawba River is the
facility's source water.The water is pumped from the river to the facility's rapid mixer where the treatment
chemicals;Sodium Hypochlorite,Sodium Bicarbonate and Poly-aluminum chloride are added in the initial steps of
the treatment process. From the rapid mixer via trough the water is transferred into flocculation/sedimentation
basins and flows across weir walls into filtration basins.Once the water has peculated through the filter media the
second dosing of treatment chemicals occur.These chemicals are Sodium Hypochlorite,Zinc orthophosphate,
fluoride(HFS)and Calcium Hydroxide(lime slurry). From this stage the water is collected in clear wells which
allows for contact time with the disinfectant and onsite storage.The water is then either pumped into the
distribution system or used as backwash for the filters.The facility uses roughly 2%of its finished potable product
to backwash filters.
The facility's waste water is produced during the flocc/sed basin cleaning and/or filter backwash process. During
these events the waste water is transferred into one of either two decant tanks.The flocc/sed waste is collected in
a large decant tank that holds the sludge and allows dewatering to take place.The waste water is released into
municipal sanitary sewer system from this tank.The sludge is then transferred to the belt press for further
dewatering.Again the waste water is released into the sanitary sewer and the resulting sludge cake is transported
via truck to a landfill. During the backwash process potable water is pumped from the clear wells and forced back
through the filter media reversely.This waste water is transferred to a smaller decant tank that slow releases into
the sanitary sewer as to not inundate the sewer system.
It is the expressed interest of the City of Morganton/Catawba River Water Treatment Plant to keep NDPES Permit
NC006194 active but continue to not discharge flow form the outfall. It is the facility's intent to not discharge flow
but to have the contingency if needed in an unforeseen future event.Thank you for your time and assistance in
this matter.
