documents, and approvals shall be submitted to the Division of Environmental
Management's Winston-Salem Regional Office.
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 a manner, as
necessary to comply with the effluent limits specified in the NPDES Permit.
You are reminded that it is mandatory for the 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 contractor's responsibilities
shall be in complying with these Acts.
The disposing, 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 under separate cover. A copy of the approved plans and
specifications shall be maintained on file by the Owner for the life of the
project.
