Air pollution: oxides of nitrogen: furnaces and water heaters.

Existing law regulates the emission of air contaminants, including the oxides of nitrogen, into the atmosphere. Existing law generally vests regulatory jurisdiction over stationary sources of air pollution to the air pollution control districts and air quality management districts and regulatory jurisdiction over mobile sources of air pollution to the State Air Resources Board.

This bill would specify that regulations adopted by districts or the state board prohibiting or restricting the sale or use of a gas-fired appliance, as defined, based on the emission limitations for oxides of nitrogen does not apply to the sale or use of that appliance if the appliance is to be installed with a propane conversion kit for propane firing only.
