1)         Less than or equal to 50 MMBtu/hr; or

2)         Greater than 50 MMBtu/hr and less than or equal to 100 MMBtu/hr and is equipped with low-NO_x burners designed by the manufacturer to meet a NO_x emission limit of not greater than 0.05 lb/MMBtu;

b)         The boiler primarily burns pipeline natural gas, butane, propane, or refinery fuel gas;
