A draft to be submitted for approval 60 days before date of operation of the facility and if manuals found to be inadequate,
the owner is required to make appropriate modifications.
A review of the approved manuals one year after initiation of plant operation and subsequent to the review, the manuals
shall be revised to reflect actual treatment plant experience.
