(1) Section 2-4-315, MCA, authorizes an interested person or member of the Legislature acting on behalf of an interested person when the Legislature is not in session, to petition an agency to adopt, amend, or repeal a rule.

(a) The petition shall be in writing, signed by or on behalf of the petitioner, and shall contain, as illustrated by template 308a (https://sosmt.gov/arm/templates), a detailed statement of:

(i) the name and address of petitioner and of any other person known by petitioner to be interested in the rule sought to be adopted, amended, or repealed;

(ii) sufficient facts to show how petitioner will be affected by adoption, amendment, or repeal of the rule;

(iii) the rule that the petitioner requests the agency adopt, amend, or repeal. Where amendment of an existing rule is sought, the rule shall be set forth in the petition with proposed deletions interlined and proposed additions underlined; and

(iv) facts and propositions of law in sufficient detail to show the reasons for adoption, amendment, or repeal of the rule.

(b) Legislators may petition an agency on behalf of interested parties through an informal letter or memorandum.

Any petition from the Legislature or its members should comply with (1)(a)(iii) and (iv).

(2) The petition shall be considered filed when received by the agency.

(i) issue an order denying the petition; or

(ii) initiate rulemaking proceedings in accordance with MAPA.
