Dear Mr. Carter.
A letter of request for an Authorization to Construct was received November 3, 1989, by

This Authorization to Construct is issued in accordance with Part III paragraph B of

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.

Upon completion of construction and prior to operation of this permitted facility, a

grade at least equivalent to the classification assigned to the wastewater treatment facilities by the
Certification Commission.
A copy of the approved plans and specifications shall be maintained on file by the Permince
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 143-215.6.
