	c. 	Provisional status. The department may classify a UST system as operating under a provisional status when the department documents a pattern of UST operation and maintenance violations under rules 567—135.3(455B) through 567—135.5(455B) and suspected release and confirmed release response actions under rules 567—135.6(455B) and 567—135.7(455B). The department shall provide the owner or operator with a notice specifying the basis for the proposed classification and a proposed remedial action plan. The objective of the remedial action plan is to provide the owner and operator an opportunity to undertake certain remedial actions sufficient to establish a reasonable likelihood that future regulatory compliance will be achieved.
The remedial action plan may include but is not limited to provisions for owner/operator training, development of a facility-specific compliance manual, more frequent third-party compliance inspections than otherwise required under rule 567—135.20(455B), monthly reporting, and retention of a third-party compliance manager/consultant. If the owner or operator and the department cannot reach agreement on a remedial action plan, the department may initiate enforcement action by issuance of an administrative order pursuant to 567—Chapter 10. This provision does not grant the owner or operator an entitlement to this procedure, and the department reserves all discretion to undertake an enforcement action and assess penalties as provided in Iowa Code sections 455B.476 and 455B.477.
	d. 	Administrative orders. The department may impose a delivery prohibition as a remedy for violations of the operation and maintenance provisions in rules 567—135.3(455B) through 567—135.5(455B) and the suspected and confirmed release response actions in rules 567—135.6(455B) and 567—135.7(455B). This remedy may be in addition to the assessment of penalties as provided in Iowa Code section 455B.476 and other appropriate injunctive relief necessary to correct violations.
	e. 	Due process prior to initiation of a delivery prohibition response action.
	(1)	Prior to imposing a delivery prohibition response action under paragraph 135.3(8)“b” above, the department will provide notice to the owner or operator or, if notice to the owner or operator cannot be confirmed, to a person in charge at the UST facility of the basis for the finding and the intent to initiate a delivery prohibition response action. Notice may be by verbal contact, by facsimile, or by regular or certified mail to the UST facility address or the owner’s or operator’s last-known address. The owner and operator will be given a minimum of one business day to provide documentation that the finding is inaccurate or that reinstatement criteria in subparagraphs 135.3(8)“b”(1) through (5) have been satisfied. Additional days and the opportunity for a telephone or in-person conference may be provided the owner and operator to contest the factual basis for a finding under subparagraphs 135.3(8)“b”(6) through (14). Additional procedural due process may be afforded the owner and operator on a case-by-case basis sufficient to satisfy Constitutional due process standards.
If insufficient information is submitted to change the finding, the department will notify the owner or operator and a person in charge at the UST facility of the final decision to impose the delivery prohibition response action.
	(2)	Provisional status. Upon a finding that an owner or operator under provisional status has failed to comply with the terms of a remedial action plan as provided above, the department may initiate a delivery prohibition response action by giving actual notice to the owner or operator of the basis for the finding of noncompliance and the department’s intent to initiate a delivery prohibition response action. The delivery prohibition response action shall not be imposed without providing the owner or operator the opportunity for an evidentiary hearing consistent with the provisions for suspension and revocation of licenses under 567—Chapter 7.
	f. 	Delivery prohibition procedure. Upon oral or written notice that the delivery prohibition response action has been imposed, the owner or operator and any person in charge of the UST facility shall be notified that they are not authorized to receive any further delivery of regulated substances until conditions for reinstatement of eligibility are satisfied. Owners and operators are required to provide the department with names and contact information for all persons who convey or deposit regulated substances to the USTs. The department will attempt to notify known persons who convey or deposit regulated substances to the USTs that they are not authorized to deliver to the USTs until further notice by the department as provided in paragraph 135.3(3)“j” and subrule 135.3(5).
The department shall visit the site and affix a “red tag” to the fill pipes or fill pipe caps of all affected USTs. It is unlawful for any person to deposit or accept a regulated substance into a UST that has a “red tag” affixed to the fill pipe or fill pipe cap. The department may allow the owner and operator to dispense and sell the remainder of existing fuel unless the department determines there is an immediate risk of a release or other risk to human health, safety or the environment. The department shall confirm in writing the basis for the delivery prohibition response action, contacts made prior to the action, and steps the owner or operator must take to reinstate fuel delivery.
	135.3(9) Secondary containment requirements for UST system installations. All new and replacement underground storage tank systems and appurtenances used for the storage and dispensing of petroleum products shall have secondary containment in accordance with this subrule. The secondary containment provision includes the installation of containment sumps.
	a. 	Tanks and piping installed or replaced after November 28, 2007, must have secondary containment that is designed, installed, and maintained according to the performance standards in subrule 135.3(1) and paragraph 135.5(3)“b.”
	(1)	The secondary containment may be manufactured as an integral part of the primary containment or constructed as a separate containment system.
	(2)	At a minimum, the secondary containment must:
	1.	Contain regulated substances leaked from the UST system until detected and removed.
	2.	Prevent the release of regulated substances into the environment at any time during the operational life of the underground storage tank system.
	3.	Be checked for evidence of a release from the tank at least every 30 days as provided in paragraph 135.5(2)“a.”
	b. 	Testing and inspection. Containment sumps shall be liquid-tight and must be inspected and tested in accordance with the following:
	(1)	Inspections for secondary containment sumps (spill catchment basins, turbine sumps, transition or intermediate sumps, and under-dispenser containment).
	1.	Inspections for secondary containment sumps shall consist of visual inspection by an Iowa-licensed installer or Iowa-certified compliance inspector every two years.
	2.	Containment sumps must be intact (no cracks or perforations) and liquid-tight, including sides and bottom.
	3.	Containment sumps must be maintained and kept free of debris, liquid, and ice at all times.
	4.	Regulated substances leaked or spilled into any containment sumps shall be immediately removed.
	(2)	Secondary containment sumps used for interstitial monitoring of piping shall be tested upon installation and periodically in accordance with subrule 135.4(12).
