The dam owner or his or her representative supervising the work on any dam or other like structure subject to the commissioner‘s jurisdiction pursuant to this chapter shall cause the work to be inspected by a registered professional engineer licensed in the state to the extent necessary to determine whether the structure will be safe and secure. For a high or significant hazard dam, or if the commissioner determines a sensitive ecological condition exists, the commissioner may place a competent inspector on the work, and the compensation for such inspector shall be shared equally by the state and by the owner. When the work has been completed to the satisfaction of the commissioner, the owner shall file with the commissioner plans and descriptions of the work as actually constructed, together with any other pertinent data. Not later than thirty days after the date the work is completed, the dam owner shall submit to the commissioner a sworn statement from the engineer who completed such inspection. Such sworn statement shall (1) attest that such engineer inspected the work and determined the dam or like structure to be safe within the parameters of the design of such dam or like structure, (2) attest that all appurtenances to such dam or like structure were built, repaired, altered or removed in conformance with plans, specifications and drawings approved by the commissioner pursuant to a permit for construction or an order issued pursuant to § 22a-402, and (3) bear the engineer’s professional seal.
