(a) Subsection 102.8, Referenced Codes and Standards, is modified by adding the following: "Any reference to a separate specialty building regulation, by title, either in this subsection or elsewhere in this code, shall be considered deleted and replaced with the title of the model code adopted by the department and in effect at the time.

(b) The permit fees for the fuel gas code are calculated the same way as provided in ARM 24.301.172, and substituting the fuel gas system for the mechanical system. The inspection fees for the fuel gas code are the same as provided in ARM 24.301.172.

(c) Section 108 of the International Fuel Gas Code will be left as is for use by certified cities, counties, and towns. The department will use 50-60-109 and 50-60-110, MCA, in cases requiring prosecution, in lieu of Section 108. When a person fails to submit required plans, obtain a permit, correct plans, or comply with an order of the department, the department will, as authorized by 50-60-109, MCA, seek injunctive relief.

(d) Section 109 of the IFGC will be left as is for use by certified cities, counties, or towns, who by 50-60-303, MCA, must provide an appeal procedure. Cities, counties, and towns may use the board of appeals created in accordance with Section 113 of the International Building Code to serve as the board of appeals. The department and state of Montana, however, will use the applicable provisions of the Montana Administrative Procedure Act in all cases of appeal, in lieu of Section 109.

(e) Subsection 307.6, Condensate pumps, is modified by adding the following exception at the end: "Exception: A water sensor with audio alarm may be substituted for an appliance/equipment disconnect to allow for continued operation of the appliance/equipment."

Cities, counties, and towns that have made the state building regulations applicable to buildings exempt from state enforcement, except for mines and buildings on mine property regulated under Title 82, chapter 4, MCA, may enforce within their jurisdictional areas the International Fuel Gas Code as adopted by those units of government.

(3) As specified in 76-2-412, MCA, fuel gas codes which are not applicable to residential occupancies may not be applied to a community residential facility serving eight or fewer persons or to a day care home serving 12 or fewer children.
