Montana Title 75. Environmental Protection § 75-20-213. Supplemental material--amendments

(1) Except as provided in 75-20-228, an application for an amendment of an application or a certificate must be in the form and contain the information that the department by rule or by order prescribes. Notice of an application must be given as set forth in 75-20-211(3) and (4).

(2) An application may be amended by an applicant any time prior to the department's recommendation. If the proposed amendment is such that it prevents the department or the agencies listed in 75-20-216(6) from carrying out their duties and responsibilities under this chapter, the department may require additional filing fees and additional amendment application review time. The total review time may not exceed 9 months from the date the department accepts a completed application for amendment.

(3) The applicant shall submit supplemental material in a timely manner as requested by the department or as offered by the applicant to explain, support, or provide the detail with respect to an item described in the original application, without filing an application for an amendment. The department's determination as to whether information is supplemental or whether an application for amendment is required is conclusive.
