(a) Within 7 days of completion of construction, reconstruction, enlargement, repair, alteration or removal of any dam to which this chapter applies, notice of completion shall be given to the Department. Within 60 days thereafter supplementary drawings or descriptive matter showing or describing the dam as actually constructed in compliance with the approval and the approved plans and specifications shall be filed with the Department in such detail as the Department may require.
(b) Upon completion of the project, the supervising engineers, having inspected the work during construction and upon finding that the work has been done as required and that the dam is safe, shall file with the Department a certificate and as-built plans demonstrating that the work has been completed in accordance with the approved design plans, specifications, and other requirements. After review of the supervising engineer's certificate and as-built plans, unless the Department has reason to believe that the dam is unsafe or is not in compliance with any applicable rule or law, the Department shall grant final approval of the work in accordance with the certificate, subject to such terms as it deems necessary for the protection of life and property.
(c) Pending issuance of the Department's final approval, the dam shall not be filled except on written consent of the Department, subject to conditions it may impose.
