Dear Mayor McMillian:
The final plans and specifications for the subject project have been
reviewed and found to be satisfactory.
Authorization is hereby granted for the upgrading of the existing 0.8
MGD extended aeration facility to consist of dividing the existing aeration
basin with a dike to form a 0.3 MG aerobic sludge storage basin and a 1.107
MG aeration basin, relocation of the existing polymer feed equipment, new
aeration basin outlet weir box, associated yard pipe, site work, electrical
work, and appurtenances.
Do not proceed with construction until the Authorization-to-Award
package, EEO, and MBE documentation/certification have 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 facilities is 50% complete.
Any groundwater, quality monitoring, as deemed necessary by the
Department, shall be provided.
