Sec. 1   RCW 70.79.060 and 1984 c 93 s 1 are each amended to read as follows:
     (1) Except as provided in subsection (2) of this section, no power boiler, low pressure boiler, or unfired pressure vessel which does not conform to the rules and regulations formulated by the board governing new construction and installation shall be installed and operated in this state after twelve months from the date upon which the first rules and regulations under this chapter pertaining to new construction and installation shall have become effective, unless the boiler or unfired pressure vessel is of special design or construction, and is not covered by the rules and regulations, nor is in any way inconsistent with such rules and regulations, in which case ((a special installation and operating permit)) an inspection certificate may at its discretion be granted by the board.
     (2) ((A special permit)) An inspection certificate may also be granted for boilers and pressure vessels manufactured before 1951 which do not comply with the code requirements of the American Society of Mechanical Engineers adopted under this chapter, if the boiler or pressure vessel is operated exclusively for the purposes of public exhibition, and the board finds, upon inspection, that operation of the boiler or pressure vessel for such purposes is not unsafe.

Sec. 2   RCW 70.79.070 and 1995 c 41 s 1 are each amended to read as follows:
     (1) All boilers and unfired pressure vessels which were in use, or installed ready for use in this state prior to the date upon which the first rules and regulations under this chapter pertaining to existing installations became effective, or during the twelve months period immediately thereafter, shall be made to conform to the rules and regulations of the board governing existing installations, and the formulae prescribed therein shall be used in determining the maximum allowable working pressure for such boilers and unfired pressure vessels.
     (2) This chapter shall not be construed as in any way preventing the use or sale of boilers or unfired vessels as referred to in subsection (1) of this section, provided they have been made to conform to the rules and regulations of the board governing existing installations, and provided, further, they have not been found upon inspection to be in an unsafe condition.
     (3) ((A special permit)) An inspection certificate may also be granted for miniature hobby boilers that do not comply with the code requirements of the American society of mechanical engineers adopted under this chapter and do not exceed any of the following limits:
     (a) Sixteen inches inside diameter of the shell;
     (b) Twenty square feet of total heating surface;
     (c) Five cubic feet of gross volume of vessel; and
     (d) One hundred fifty p.s.i.g. maximum allowable working pressure, and if the boiler is to be operated exclusively not for commercial or industrial use and the department of labor and industries finds, upon inspection, that operation of the boiler for such purposes is not unsafe.

Sec. 3   RCW 70.79.080 and 2005 c 22 s 1 are each amended to read as follows:
     This chapter shall not apply to the following boilers, unfired pressure vessels and domestic hot water tanks:
     (1) Boilers and unfired pressure vessels under federal regulation or operated by any railroad subject to the provisions of the interstate commerce act;
     (2) Unfired pressure vessels meeting the requirements of the interstate commerce commission for shipment of liquids or gases under pressure;
     (3) Air tanks located on vehicles operating under the rules of other state authorities and used for carrying passengers, or freight;
     (4) Air tanks installed on the right-of-way of railroads and used directly in the operation of trains;
     (5) Unfired pressure vessels having a volume of five cubic feet or less when not located in places of public assembly;
     (6) Unfired pressure vessels designed for a pressure not exceeding fifteen pounds per square inch gauge;
     (7) Tanks used in connection with heating water for domestic and/or residential purposes;
     (8) Boilers and unfired pressure vessels in cities having ordinances which are enforced and which have requirements equal to or higher than those provided for under this chapter, covering the installation, operation, maintenance and inspection of boilers and unfired pressure vessels;
     (9) Tanks containing water with no air cushion and no direct source of energy that operate at ((a)) ambient temperature ((of one hundred thirty degrees Fahrenheit or less));
     (10) Electric boilers:
     (a) Having a tank volume of not more than one and one-half cubic feet;
     (b) Having a maximum allowable working pressure of one hundred pounds per square inch or less, with a pressure relief system to prevent excess pressure; and
     (c) If constructed after June 10, 1994, constructed to American society of mechanical engineers code, or approved or otherwise certified by a nationally recognized or recognized foreign testing laboratory or construction code, including but not limited to Underwriters Laboratories, Edison Testing Laboratory, or Instituto Superiore Per La Prevenzione E La Sicurezza Del Lavoro;
     (11) Electrical switchgear and control apparatus that have no external source of energy to maintain pressure and are located in restricted access areas under the control of an electric utility;
     (12) Regardless of location, unfired pressure vessels ((and hot water heaters)) less than one and one-half cubic feet (11.25 gallons) in volume ((with a safety valve setting of one hundred fifty pounds per square inch gauge (psig) or less,)) or less than six inches in diameter ((and less than five cubic feet (37.5 gallons) in volume with a safety valve set at any pressure, or less than fifteen psig containing substances other than steam, lethal substances, or liquids with low flash points)) with no limitation on the length of the vessel or pressure;
     (13) Domestic hot water heaters less than one and one-half cubic feet (11.25 gallons) in volume with a safety valve setting of one hundred fifty pounds per square inch gauge or less
.

Sec. 4   RCW 70.79.090 and 2005 c 22 s 2 are each amended to read as follows:
