400 CMR, § 2.12
In municipalities where the Cape Cod Commission or Martha's Vineyard Commission have the authority to review permit applications, the municipality shall consult with the Cape Cod Commission or Martha's Vineyard Commission before commencing with a project on a PDS. The Commission and the municipality shall work together to consider any areas of potential concern or conflict prior to issuing applications for that project, and make every reasonable effort to expedite the processing of such applications. In municipalities that fall within the jurisdiction of either Commission, the ISO-day review period will be tolled on the day the referral is made to the Cape Cod Commission and the Martha's Vineyard Commission and will resume when those bodies complete their review.
