Do not proceed with construction until the Authorization-to-Award
package, EEO, and MBE documentation/certification has been reviewed, and
you are in receipt of our approval if Federal Funding is desired for
project construction.
The Permittee shall employ an actively State certified wastewater
treatment plant operator to be in responsible charge of the wastewater
treatment facilities. Such operator must hold a valid State certificate of
the grade at least equivalent to the classification assigned to the wastewater
treatment facilities by the Certification Commission. When a new chief
operator must be obtained to be in responsible charge of the new facilities,
it is required that this be done by the time the construction of the facili-
ties is 50% completed.
This Authorization-to-Construct is issued in accordance with Part III,
Paragraph C of NPDES Permit No. P:00026611 issued August 23, 1982, and shall
be subject to revocation unless the wastewater treatment facilities are con-
structed in accordance with the approved plans, specifications, supporting
documents, and are in compliance with the conditions and limitations speci-
fied in Permit No. NC0026611.
During the construction of the proposed additions/modifications,
the Permittee shall continue to properly maintain and operate the
existing wastewater treatment facilities at all times, and in such
manner, as necessary to comply with the effluent limits specified in the
NPDES Permit.
You are reminded that it is mandatory for project to be constructed in
accordance with the North Carolina Sedimentation Pollution Control Act; and .
when applicable, the North Carolina Dam Safety Act. In addition, the
specifications must clearly state what the contractors responsibilities
shall be in complying with these acts.
The selling or free distribution of wet, dried, composted sludge or
sludge like materials from wastewater facilities without prior review and
approval by this Division is illegal.
One (1) set of final approved plans and specifications is to be
forwarded to you, one (1) set to the Environmental Protection Agency (EPA),
and two (2) sets to the Corps of Engineers.
