17-229-103 Me. Code R. § II-7
Recognizing that the activities of MTA under this Subchapter and those of MaineDOT under Subchapter I might sometimes be conducted more advantageously or economically on a joint basis, those agencies may agree that one or more of the activities described in this Subchapter and/or the parallel provisions of Subchapter I may be conducted by one of the agencies on behalf of both, with each agency retaining ultimate authority and responsibility for transportation planning decisions, capital investment decisions and project decisions under its jurisdiction. In discharging its responsibilities under this Subchapter, MTA may rely upon one or more of the evaluations, assessments or decisions reached or developed by MaineDOT under Subchapter I.
MaineDOT may consult with the MTA on any transportation plans submitted to MaineDOT pursuant to Subchapter III if those plans are submitted by a municipality through which the Turnpike runs through, a municipality adjacent to a municipality the Turnpike runs through, or a regional entity whose members include any such community. Any such plans will be submitted to MTA as early in the review process as possible to ensure that MTA's comments on the plans may be thoroughly considered by MaineDOT.
