Dear Mr. Williams:
A letter of request for an Authorization to Construct was received May 22, 1990 by the

be satisfactory. Authorization is hereby granted for the cleaning and rehabilitation of an existing 45
foot diameter by 22 foot side wall depth sludge digester and replacement of the roof on the digester
floating cover.
This Authorization to Construct is issued in accordance with Part III paragraph C of
NPDES Permit No. NCO020559 issued August 31, 1989, and shall be subject to revocation unless
the wastewater treatment facilities are constructed in accordance with the conditions and limitations
specified in Permit No. NC0020559.
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. The City of Henderson is fully responsible for the proper disposal of all sludge and
solids removed as part of the rehabilitation process.
In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Pernuttee 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.
The Raleigh Regional Office, phone no. [phone], shall be notified at least forty-
eight (48) hours in advance of operation of the installed facilities so that an in -place inspection can
be made. Such notification to the regional supervisor shall be made during the normal office hours
from 8:00 a.m. until 5.00 p.m. on Monday through Friday, excluding State Holidays.
