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.
1. 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.
2. The owner shall contact the area engineer
					 and request that a final inspection of the completed construction be made so
					 that either a conditional, or a final, CTO can be issued. 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.
3. A closure plan
					 should be submitted with or prior to the statement of completion of
