Amends GS 143-215.27 by prohibiting the Department of Environmental Quality (DEQ) from withholding the approval of an application for repair or alteration of a phased compliance eligible dam only because the repair or alteration will not fully meet the requirements of the Dam Safety Law of 1967 (Law) and related implementation rules if the project will not increase the height or impoundment capacity of the dam and it will not increase the risk to human life or property. Amends GS 143-215.25 by defining a phased compliance eligible dam as a dam that (1) is categorized as high hazard by DEQ; (2) was constructed prior to January 1, 1968; and (3) is not owned by a unit of local government, special district, or public authority, as those terms are defined in GS 159-7.
