Okla. Stat. tit. 82, § 82-105.25: Notice of completion - Inspection

On the date set for the completion of the work, or prior

thereto, upon notice from the owner that the work has been

completed, the Board shall cause the work to be inspected after due

notice to the owner of the permit. Such inspection shall be

thorough and complete, in order to determine the actual capacity of

the works, their safety and efficiency. If not properly and safely

constructed, the Board may require the necessary changes to be made

within a reasonable time and shall not issue a certificate of

completion until such changes are made. Failure to make such

changes within the time required by the Board shall cause the

postponement of the priority under the permit for such time as may

elapse from the date for completing such changes until made to the

satisfaction of the Board and applications subsequent in time shall

have the benefit of such postponement of priority; provided, the

Board may accept the report of inspection by a registered

professional engineer.
