The Commission's Rules of Practice and Procedure require that an order instituting rulemaking preliminarily determine the category of the proceeding and the need for hearing.58 As a preliminary matter, we determine that this proceeding is quasi-legislative. As provided in Rule 6(c) (2), any person who objects to the preliminary categorization of this rulemaking as "quasi-legislative" or to the preliminary hearing determination, shall file and serve its objections with its opening comments.
