A. Issuance. Upon approval of the proposed design by the area engineer, including any submitted plans and specifications, if required, the director will issue a CTC to the owner within 15 days of such approval to construct or modify his sewerage systems or treatment works in accordance with the approved design and submitted plans and specifications.

B. Revisions. Any deviations from the approved design or the submitted plans and specifications significantly (25% or more variation from original for sewerage systems or treatment works and 20% or more for biosolids use facilities) affecting hydraulic conditions (flow profile), unit operations capacity, the functioning of the sewage treatment process, or the quality of treated effluent discharged, must be approved by the area engineer before any such changes are made. Revised plans and specifications shall be submitted in time to allow 30 days for the review, evaluation and approval of such plans or specifications before any construction work that will be affected by such changes is begun, unless the owner has received approval to proceed from the department prior to either a formal submittal of revisions, or the department approval of submitted revisions.

C. Completion of construction. A statement shall be submitted by the owner assuring completion of construction and an inspection of the constructed system works will be scheduled in accordance with the provisions of this chapter.

Upon completion of the construction or modification of the sewerage systems or treatment works, the owner shall submit to the area engineer a statement signed by a licensed professional engineer stating that the construction work was completed in accordance with the approved plans and specifications, or revised only in accordance with the provisions of subsection B of this section. This statement is called a Statement of Completion of Construction and shall be based upon inspections of the sewerage systems or treatment works during and after construction or modifications that are adequate to ensure the truth of the statement.

Within 30 days after placing a new or modified sewerage systems or treatment works into operation, the effluent produced should be sampled and tested in a manner sufficient to demonstrate compliance with approved specifications and permit requirements. The area engineer shall be notified of the time and place of the tests and the results of the tests shall be sent to the area engineer for evaluation as part of the final CTO.
