Re: NPDES Permit NCO084212
Sparks Road WTP
Davie County, NC
Dear Mrs. Stephens:
On behalf of the Davie County Water System, we hereby request renewal of the
above referenced permit (see authorization attached). Also attached is NPDES
Permit Application — Short Form C for the above referenced facility.
The Spark Road Water Treatment Plant is currently permitted to discharge
process wastewater resulting from the purification of raw river water during
production of potable water for the Davie County water system. The water plant's
rated capacity is 3.0 mgd. The only process change occurring since the last
renewal is that Ferric Sulfate began to be used as a coagulant instead of an
alum/polymer blend in October of 2003.
Please call with any questions.
Very truly yours,
Grey Engineering, Inc.
John C. Grey, Jr. PE
President

Sludge Disposal at the Sparks Road Water Treatment Plant
Water treatment process wastewater flows from the treatment facility into two
parallel treatment lagoons. Sludge from the lagoons has not yet been disposed of
since the plant was constructed. However, it is anticipated that the lagoons will
be cleaned out and the contents land applied within the next twelve months.
