PUBLISHER'S NOTE: The secretary of state has
				  determined that the publication of the entire text of the material which is
				  incorporated by reference as a portion of this rule would be unduly cumbersome
				  or expensive. This material as incorporated by reference in this rule shall be
				  maintained by the agency at its headquarters and shall be made available to the
				  public for inspection and copying at no more than the actual cost of
				  reproduction. This note applies only to the reference material. The entire text
				  of the rule is printed here.
(1) Owners and operators must notify the
				department in writing, on forms provided by the department, at least thirty
				(30) days before beginning either permanent closure or a change in service of
				an underground storage tank (UST), unless this action is in response to
				corrective action or the department approves a shorter time period. The
				required assessment of the excavation zone under
				10 CSR
				26-2.062 must be performed after notifying the
				department but before completion of the permanent closure or a change in
				service. The closure notice is valid for one hundred eighty (180) days. If
				permanent closure or change in service does not commence within one hundred
				eighty (180) days of the date the notice is received by the department, a new
				closure notice must be submitted prior to commencing closure
				activities.
(2) To permanently
				close a tank, owners and operators must empty and clean it by removing all
				liquids and accumulated sludges. Liquids and sludges shall be managed in
				accordance with state and federal regulations. All tanks taken out of service
				permanently must also be either removed from the ground or filled with an inert
				solid material.
(3) Continued use
				of a UST system to store a nonregulated substance is a change in service.
				Before a change in service, owners and operators must empty and clean the tank
				by removing all liquid and accumulated sludge and conduct a site assessment in
				accordance with
				10 CSR
				26-2.062.
(4) Lining a steel tank with a material that
				is approved as a stand-alone underground storage tank under Underwriters'
				Laboratories Standard 1316, revised 2006, is a change in service. This document
