Section 173-306-340. Engineering reports, plans and specifications required in permits.

(1) Before constructing or modifying disposal facilities, final engineering reports, plans and specifications must be submitted to and approved by the department according to a compliance schedule specified in the permit. The engineering report for a disposal facility must be sufficiently final so that plans and specifications can be developed from it without substantial changes.

(2) All final engineering reports, plans and specifications should be submitted by the owner or operator consistent with the compliance schedule in the permit and at least thirty days before the time approval is needed. The department will review and comment on and may approve (or conditionally approve) or disapprove the plans and reports within the thirty-day period unless circumstances prevent, in which case the owner or operator will be notified and informed of the reason for the delay.

(3) The final engineering report may be submitted before or concurrently with the final plans and specifications.

(4) The department will review the documents to ascertain that the proposed facility will be:

(a) Designed, constructed, operated, maintained, and closed to meet the requirements of the permit issued under this chapter; and

(b) Consistent with good engineering practices.

(5) Within thirty days after acceptance by the owner or operator of or modification to an ash disposal facility, a professional engineer in responsible charge of inspection of the project shall submit to the department one complete set of record drawings or as-builts, and a declaration stating the facilities were constructed in accordance with the provisions of the construction quality assurance plan and without significant change from the department approved plans and specifications.
