Dear Mr. Hudson:
A letter of request for an Authorization to Construct was received August 19, 1994 by the Division
and final plans and specifications for the subject project have been reviewed and found to be satisfactory.
Authorization is hereby granted for the removal of the residuals and existing clay liners in the aerobic
digester and aeration basin No. 1; construction of concrete basins for the aerobic digester and aeration
basin No. 1 and all the associated valves, piping, and appurtenances. The concrete basins for"the digester
and aeration basin No. 1 shall be constructed to maintain the current volume of both units (APPROVED
AMENDED PLANS ATTACHED). Disposal of soils, decant, and residuals shall comply with all
applicable laws and permits.
Any groundwater monitoring, as deemed necessary by the Division, shall be provided.
This Authorization to Construct is issued in accordance with Part III, Paragraph A of NPDES
Permit No. NCO020591 issued July 29, 1994, and shall be subject to revocation unless the wastewater
treatment facilities are constructed in accordance with the conditions and limitations spc. ified in Permit No.
NCO0205 91.
Any subsequent plant design plans must indicate that the existing line from manhole "G" to
manhole "#5" has been plugged and no bypass will occur pursuant to 15A NCAC 2H .02190)(1). The
letter dated November 9, 1994 from you stating that the bypass is sealed is adequate for this Authorization
to Construct.
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.
