Based upon comments received, staff proposes two minor changes to the proposed amendments contained in the public notice package. Due to a clerical error, an older draft for 2-1-128 was included. The description in the staff report discusses the correct staff proposal. The second change incorporates clarifying language into 2-1-233 suggested by an industry commentor that does not affect the intent of the section. Staff requests that the language included on the errata sheet be incorporated into its proposed amendments.
