for extended aeration type except when eventual
conversion to step aeration type is contemplated.

NOTE: Delete reference to access ladder when not
allowed. Delete references and requirements for
access ladder as Contractor's option unless it can
be justified on an economic and technical basis.
Although more expensive, a stairway is preferable in
that it provides safer and easier access to
platforms and walkways.
