In recognition of the fact that attachment agreements are the result of arms-length negotiations conducted within regulatorily-established perimeters and subject to administrative review, all such agreements filed with the Commission shall be presumed to comply with the standards set out in §7 of these regulations.
Any proceeding under this section shall be conducted in accordance with the Delaware Administrative Procedures Act, the Commission's "Rules of Practice" and these Regulations [to the extent each may be applicable. However, to the extent the matters at issue involve the Commission's legislative ratemaking authority, the Commission may proceed accordingly, and the utility shall have the burden of proof to establish that its proposed terms, conditions, and rates for the proposed attachment are just and reasonable.]
