• It is the Divisions understanding that the proposed interlocking sheet piles between the
equalization basin and aeration basin number 2 and between aeration basin number 1

curtains will be installed in place of the interlocking sheet piles. This authorization to
construct is being issued with the understanding that as -built plans, for the installation
of floating curtains, will be submitted for Division review upon completion.
