105 CMR, § 100.425
Unless otherwise deemed allowable by the Commissioner, no amendment shall be accepted that, in the opinion of the Commissioner, substantially alters the Proposed Project in nature, scope, costs, or financing, or in any way substantially alters or affects the Department's evaluation of the Proposed Project. 105 CMR 100.425 does not preclude the Department from requesting additional information, or making reasonable accommodations for any necessary technical corrections by the Applicant, or other changes based on updated information related to the Proposed Project. Any proposed amendments which are deemed impermissible by the Commissioner, and which result in the Applicant's inability to proceed with its filing, shall automatically result in a dismissal and the need for the Applicant to file a new Application.
