The state liquor commission shall develop and maintain a formal written store plan for its retail liquor stores. This plan shall establish goals and policies related to the number, size, and staffing patterns of state operated retail liquor stores to ensure the efficient and effective operation of the state store system. The plan shall be reviewed and revised as necessary and shall include, but not be limited to, policies related to:
   I. The operational definition of a marginal store, identification of such stores, and specific plans to consolidate or otherwise improve the profitability of such stores.
   II. The optimum size, location, and staffing pattern of stores to maximize their profitability. This shall include a plan to increase use of part-time employees to reduce store personnel costs and a formula for determining appropriate rental payments for leased stores.
   III. Plans for the expansion of the existing store system where such expansion is justified.
