Dear Mayor VonCanon:
A letter of request for an Authorization to Construct was received June 29, 1990 by the
Division and final plans and specifications for the subject project have been reviewed and found to
be satisfactory. Authorization is hereby granted for the construction of a 330,000 gpd wastewater
treatment plant consisting of a new bar screen, a new grit removal chamber unit, a new 40,000
gallon flow equalization basin with fine bubble diffusers and dual 260 gpm submersible pumps, a
new flow splitter box, retrofit the existing package plant into a 200,000 gallon aeration basin with
fine bubble diffusers and a total blower capacity of 900 cfm, a new secondary clarifier with a
diameter of 34 feet and a sidewater depth of 14 feet, a new sludge pump station with dual 245 gpm
pumps, a new 118,000 gallon aerated sludge digester with two 50 hp blowers, a new ultraviolet
disinfection system, retrofit the existing sludge drying beds and provide a new roof for the drying
beds, a new sludge storage pad approximately 85 ft x 55 ft and all the associated piping, valves,
and appurtenances with discharge of treated wastewater into the Elk River classified C-Trout
waters.
This Authorization to Construct is issued in accordance with Part III paragraph B of
NPDES Permit No. NC0032115 issued October 3, 1988, and shall be subject to revocation unless
the wastewater treatment facilities are constructed in accordance with the conditions and limitations
specified in Permit No. NC0032115.
The sludge generated from these treatment facilities must be disposed of in accordance with
G.S. 143-215.1 and in a manner approved by the North Carolina Division of Environmental
Management.
In the event that the 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 wastewater
treatment or disposal facilities.
