Part II - DESCRIPTINOF PROPOSED TREATMENT WORKS
There are no .xisting wastewater treatment facilities at the Gastonia
later Treatment Pl ;i:rt. Filter backwash water and sludge from the settling
basins are bei Ili? li scharged directly to tie "rface waters without
treatment. The City plans to construct a wastewater collection system
at the water plant and discharge the wastewater to the sewerage system
for treatment at the Long Creek Wastewater Treatment Plant.
The City has proposed a schedule for the construction of the proposed
facilities in order to eliminate the discharge to the surface waters
of the State. However, this Office felt that an excessive amount of
time (two years) to accomplish the proposed construction had been projected
by the City. A meeting was held in this Office on June 12, 1978, with
Mr. Graham Wilson and Mr. John Schuler of the City of Gastonia; Mr. Dick
Moore and Mr. Henry Moore of Moore, Gardner & Associates; and Mr. Rex
Gleason and Ar. K,aitii ilvercash of the Division of Environmental Management
in attendance to discuss the proposed schedule. The City does not feel
that a shorter time schedule would be feasible. It is, therefore,
recommended that a Special Order by Consent be prepared which includes

the proposed time schedule and that a Permit be issued containing the
final effluent limitations assigned to this point of discharge.
