  (2)  Keep available for examination by the director accurate records showing the date and actual time the object is out of service and the reason it is out of service.
  (3)  Keep available for examination by the director chemical physical laboratory analyses of samples of the object water taken at regular intervals of not more than forty-eight hours of operation as will adequately show the condition of the water and any elements or characteristics of the water which are capable of producing corrosion or other deterioration of the object or its parts.
  5.  a.  An object that meets all of the following criteria shall be inspected at least once each year externally while under pressure and at least once every four years internally while not under pressure, unless the director determines an earlier inspection is warranted:
  (1)  The object is a boiler with one hundred thousand pounds per hour or more capacity, or the object is an unfired steam pressure vessel or a regulated appurtenance that is part of the same system as a boiler with one hundred thousand pounds per hour or more capacity.
  (2)  The object contains only water subject to internal continuous water treatment under the direct supervision of a graduate engineer or chemist, or one having equivalent experience in the treatment of boiler water.
  (3)  The water treatment is for the purpose of controlling and limiting serious corrosion and other deteriorating factors.

29 C.F.R. §1910.119
 and the owner demonstrates such compliance to a special inspector or the director. The unfired steam pressure vessel must also be included as process safety management process equipment in the owner of the unfired steam pressure vessel’s process safety management program.
  b.  The owner or user of an object that meets the criteria in paragraph “a” shall do the following:
  (1)  At any time the director, a special inspector, or the supervisor of the water treatment deems a hydrostatic test necessary to determine the safety of an object, conduct the test under the supervision of the director.
  (2)  Keep available for examination by the director accurate records showing the date and actual time the object is out of service and the reason it is out of service.
  (3)  Arrange for an internal inspection of the object during each planned outage by a special inspector or the director.
  (4)  Keep for examination by the director accurate records showing the chemical physical laboratory analyses of samples of the object’s water taken at regular intervals of not more than forty-eight hours of operation adequate to show the condition of the water and any elements or characteristics of the water that are capable of producing corrosion or other deterioration of the object or its parts.
  6.  a.  The owner of an object that meets all of the criteria in subsection 4, paragraph “a”, may request from the director an internal inspection time period of longer than two years, but not to exceed seven years, if the object is an integral part of a continuous operation of a process that is covered by and compliant with the occupational safety and health administration process safety management standard contained in 
29 C.F.R. §1910.119
 and has a planned outage schedule that is longer than two years.
  b.  The director may grant the longer inspection interval if the owner is able to demonstrate to the director that the object is in compliance with the process safety management standard contained in 
29 C.F.R. §1910.119

Upon request by the director, the owner shall provide the director with the findings of any previous inspections of the object under this chapter.
  c.  If the director intends to deny the request, the director shall contact the owner prior to the denial and provide an opportunity for the owner to address the reasons for the intended denial. If the board has not adopted rules pursuant to section 89.14, subsection 11, the lack of adoption shall not be grounds for the director not to consider a request for a longer inspection interval pursuant to this subsection.

The inspections conducted within each two-year period shall include an external inspection conducted while the boiler is operating and an internal inspection, where construction permits. No more than one inspection shall be conducted per six-month period. An internal inspection of an unfired steam pressure vessel or low pressure steam boiler may be required at any time by the director upon the observation by an inspector of conditions, enumerated by the director through rules, warranting an internal inspection. If a low pressure steam boiler is in dry lay-up, an internal inspection shall be conducted in lieu of an external inspection. For purposes of this subsection, “dry lay-up” means a process whereby a boiler is taken out of service for a period of six months or longer, drained, dried, and cleaned, and measures to prevent corrosion are performed on the boiler. 
  10.  An internal inspection shall not be required on an unfired steam pressure vessel that was manufactured without an inspection opening.
  11.  An exhibition boiler does not require an annual inspection certificate but special inspections may be requested by the owner or an event’s management to be performed by the director. Upon the completion of an exhibition boiler inspection, a written condition report shall be prepared by the director regarding the condition of the exhibition boiler’s boiler or pressure vessel. This report will be issued to the owner and the management of all events at which the exhibition boiler is to be operated. The event’s management is responsible for the decision on whether the exhibition boiler should be operated and shall inform the department of the event’s management’s decision. The event’s management is responsible for any injuries which result from the operation of any exhibition boiler approved for use at the event by the event’s management. A repair symbol, known as the “R” stamp, is not required for repairs made to exhibition boilers pursuant to the rules regarding inspections and repair of exhibition boilers as adopted by the director, pursuant to chapter 17A.
  12.  An inspection report created pursuant to this chapter that requires modification, alteration, or change shall be in writing and shall cite the state law or rule or the ASME code section allegedly violated.
