5.1.b.6.A. The owner or operator shall ensure that any changes to the regulated AST system noted in the monthly inspection that could negatively affect AST system integrity are further assessed by a qualified Professional Engineer, API or STI certified inspector, or by a person holding certification under another program approved by the Secretary as soon as is practical, but in no case more than thirty (30) days from the inspection.

5.1.b.6.B. The owner or operator shall ensure that malfunctioning equipment and appurtenances are repaired, replaced, or removed from service, immediately as possible, but in no case more than thirty (30) days from discovery that the equipment is malfunctioning, in order to prevent releases. The Secretary may specify another reasonable time period for completion of repairs.

5.1.b.6.C. The owner or operator shall ensure weakening equipment and appurtenances that pose an imminent threat of failure that could result in a release are repaired and/or replaced in a timely manner, but no longer than thirty (30) days, after discovering, or being notified by the Secretary, that the equipment is at risk for failure.

5.3.b.2. Subsequent internal inspections required under paragraph 5.3.b.1 shall be performed, at a minimum, every twenty (20) years for tanks without a Release Prevention Barrier or thirty (30) years with a Release Prevention Barrier, unless findings from an inspection reveal that corrosion, deterioration or other specific conditions necessitate a more frequent internal inspection.

5.3.c. As an alternative to the aforementioned intervals for internal inspections, an owner or operator may choose to establish an initial or subsequent internal inspection schedule using the Risk Based Inspection (RBI) assessment methodology in API 653 and API RP 580.

5.3.c.1 The RBI assessment shall be performed by a person or persons who have inspection and engineering expertise and are knowledgeable in the proper application of API RP 580 principles, tank design, construction, and modes of deterioration.

5.3.c.2. An RBI assessment must be tank specific.

5.3.c.3. A person or persons having inspection and engineering expertise must determine the appropriateness of RBI assessments for the tank based upon the level of tank information available. The RBI assessment methodology may not be appropriate if a number of the "likelihood factors" and "consequence factors" described in API 653 and API RP 580 are unknown.

5.3.d. When an internal inspection is due for a regulated AST, it should be scheduled by the tank owner or operator to coincide with the annual inspection required by subsection 5.2 of this Rule in order to collect the maximum amount of data for determining fitness for service of the AST.

5.3.d.1. An internal inspection must be certified by a Professional Engineer, an API certified inspector, a STI certified inspector or by a person holding certification under another program approved by the secretary.

5.3.e. For an existing AST, if an internal inspection of the regulated AST has been conducted in accordance with the schedule recommended by its manufacturer or the American Petroleum Institute or Steel Tank Institute before the effective date of this rule, the internal inspection is acceptable, provided that:

5.3.e.1. The inspection, at a minimum, addresses the required items for assessment from subdivision 5.3.a; and

5.3.e.2. The last internal inspection was performed within the last thirty (30) years of the effective date of this Rule or an alternative time period that was previously determined through a RBI performed in accordance with API 653 and API 580.

5.3.e.3. The internal inspection is reviewed, approved, and certified by a Professional Engineer, an API certified inspector, a STI certified inspector or by a person holding certification under another program approved by the secretary.

5.3.f. If an existing regulated AST has not had an internal inspection, an internal inspection must be performed within:

5.3.f.1. One (1) year of the effective date of the Rule for tanks that are greater than seventy-five (75) years old;

5.3.g.1. Immediately remove the AST from active service;

5.3.g.2. Empty the AST;

5.3.g.3. Upgrade the AST to meet or exceed the minimum requirements for AST system integrity and provide a certification that the AST has been made Fit for Service signed by a Professional Engineer, an API certified inspector, a STI certified inspector or by a person holding certification under another program approved by the secretary; or

5.3.g.4. Permanently properly close the AST.

5.4. Damaged Tanks.

5.4.a. An owner or operator shall ensure that a regulated AST system subjected to damage is evaluated by a Professional Engineer, an API certified inspector or a STI certified inspector to determine if the AST system is Fit for Service. Damage conditions include, but are not limited to the following;
