A letter of request for an Authorization to Construct was received on April 11, 1995 by the

(3) Installation of a new six inch Parshall flume,
(4) Conversion of the existing 0.3 MGD aeration basin into a 0.3 MGD sludge digester, and

The final system shall consist of flow equalization, pH adjustment, oil skimming, dual aeration basins,
clarifier, effluent flow measurement, sludge pump station, dual aerobic digesters, aerated sludge holding

This Authorization to Construct is issued in accordance with Part III, Paragraph A of NPDES

classification assigned to the wastewater treatment facilities by the Certification Commission. The
Permittee must also employ a certified back-up operator of the appropriate type and grade to comply with

submit a letter to the Certification Commission which designates the operator in responsible charge within
thirty days after the wastewater treatment facilities are 50% complete.
A copy of the approved plans and specifications shall be maintained on file by the Permittee for the
life of the facility.
Failure to abide by the requirements contained in this Authorization to Construct may subject the
Permittee to an enforcement action by the Division of Environmental Management in accordance with
North Carolina General Statute 143-215.6A to 143-215.6C.
