S.F. 118 Section 1. Section 89.3, subsections 7 and 8, Code 2019, are 1 amended to read as follows: 2 7. Internal inspections of steel hot water boilers shall be 3 conducted once every six years. External operating inspections 4 shall be conducted annually in years other than the year in 5 which internal inspections are conducted . 6 8. Inspections of unfired steam pressure vessels operating 7 in excess of fifteen pounds per square inch and low pressure 8 steam boilers shall be conducted at least once each calendar 9 year. The inspections conducted within each two-year period 10 shall include an external inspection conducted while the boiler 11 is operating and an internal inspection, where construction 12 permits. No more than one inspection shall be conducted per 13 six-month period. An internal inspection of an unfired steam 14 pressure vessel or low pressure steam boiler may be required 15 at any time by the commissioner upon the observation by an 16 inspector of conditions, enumerated by the commissioner through 17 rules, warranting an internal inspection. If a low pressure 18 steam boiler is in dry lay-up, an internal inspection shall be 19 conducted in lieu of an external inspection. For purposes of 20 this subsection , “dry lay-up” means a process whereby a boiler 21 is taken out of service for a period of six months or longer, 22 drained, dried, and cleaned, and measures to prevent corrosion 23 are performed on the boiler. 24 Sec. 2.

Water heaters used for potable water if the capacity 27 is less than or equal to one hundred twenty fifty gallons, 28 the burner input is less than or equal to two hundred fifty 29 thousand British thermal units, and the maximum allowable 30 working pressure is less than one hundred sixty pounds per 31 square inch. 32 EXPLANATION 33 The inclusion of this explanation does not constitute agreement with 34 the explanation’s substance by the members of the general assembly. 35 -1- LSB 1747ST (3) 88 je/rn 1/ 2

S.F. 118 This bill relates to boiler and unfired steam pressure 1 vessel inspections conducted pursuant to Code chapter 89. 2 The bill strikes a requirement that external operating 3 inspections of steel hot water heating boilers be conducted in 4 years other than the year in which internal inspections are 5 conducted. The bill also changes the term “steel hot water 6 heating boiler” to “steel hot water boiler”. 7 The bill strikes a requirement that an internal inspection 8 of a low pressure steam boiler be conducted in lieu of an 9 external inspection if the boiler is in dry lay-up. 10 The bill modifies an exemption from Code chapter 89 by 11 providing that the exemption applies to water heaters used 12 for potable water if the capacity is less than or equal to 50 13 gallons and the burner input is less than or equal to 50,000 14 British thermal units, rather than 120 gallons and 200,000 15 British thermal units as provided under current law. 16 -2- LSB 1747ST (3) 88 je/rn 2/ 2
