| (2) Inspection. During construction, the project may
be visited by a representative of the commission during normal working
hours to establish general compliance with the plans and technical
specifications approved by the commission.
(3) Operation and maintenance manual. Prior to completion
of construction of a new wastewater treatment plant or plant expansion,
an operation and maintenance manual covering the recommended operating
procedures and maintenance practices for the entire facility shall
be furnished to the sewerage system owner by the design engineer.
The design engineer shall submit a letter to the commission certifying
that this action has been performed and shall furnish a copy of the
operation and maintenance manual to the commission upon request.
(4) Sludge management implementation plan. The design
engineer shall prepare an implementation plan for the selected sludge
management method. The plan shall identify regulatory requirements
of state and federal agencies. The plan shall also include requirements
for selected contingency alternatives.
(5) Authorization to discharge. For treatment plant
projects, the owner is required to secure proper authorization from
the commission prior to initiation of construction. No discharge shall
be authorized without a discharge permit. In no case shall bypassing
of partially treated wastewater be authorized during construction
without an order for such discharge from the commission. Also see §317.4(a)(3)
of this title (relating to Wastewater Treatment Facilities).
(f) Variance. A variance from the design criteria herein
may be granted by the commission if the variance would not result
in an unreasonable risk to treatment plant performance, public health,
or the waters in the state. Requests for variances must be submitted
in writing by the design engineer and must, for each affected item,
include a detailed engineering justification.
