Administrative Rules of Montana › Department 17 - ENVIRONMENTAL QUALITY › Chapter 17.8 - AIR QUALITY › Subchapter 17.8.3 - Emission Standards › Rule 17.8.320 - WOOD-WASTE BURNERS

Current through Register Vol. 13, July 5, 2024
(1) It is hereby
				declared to be the policy of the department to encourage the complete
				utilization of wood-waste residues and to restrict, wherever reasonably
				practical, the disposal of wood-waste residues by combustion in wood-waste
				burners. Recent technological and economic developments have enhanced the
				degree to which wood-waste residues currently being disposed of in wood-waste
				burners may be utilized or otherwise disposed of in ways not damaging the
				environment. While recognizing that complete utilization of wood-waste is not
				presently possible in all instances, this policy applies to the extent
				practical and consistent with economic and geographical conditions in
				Montana.
(2) Construction,
				reconstruction, or substantial alteration of wood-waste burners is prohibited
				unless the requirements of subchapter 7 of this chapter have been
				met.
(3) No person shall cause or
				authorize to be discharged into the outdoor atmosphere from any wood-waste
				burner any emissions which exhibit an opacity of 20% or greater averaged over
				six consecutive minutes. The provisions of this section may be exceeded for not
				more than 60 minutes in eight consecutive hours for building of fires in
				wood-waste burners.
(4) A
				thermocouple and a recording pyrometer or other temperature measurement and
				recording device approved by the department shall be installed and maintained
				on each wood-waste burner. The thermocouple shall be installed at a location
				near the center of the opening for the exit gases, or at another location
				approved by the department.
(5)
				Except as provided in (6), a minimum temperature of 700ºF shall be
				maintained during normal operation of all wood-waste burners. A normal start-up
				period of one hour is allowed during which the 700ºF minimum temperature
				does not apply. The burner shall maintain 700ºF operating temperature
				until the fuel feed is stopped for the day.
(6) Wood-waste burners in existence on
				February 10, 1989, do not have to comply with the requirements of (5) if they
				are located outside of PM nonattainment areas.
(7) The owner or operator of a wood-waste
				burner must maintain a daily written log of the wood-waste burner's operation
				to determine optimum patterns of operations for various fuel and atmospheric
				conditions. The log shall include, but not be limited to, the time of day,
				draft settings, exit gas temperature, type of fuel, and atmospheric conditions.
				The log or a copy of it must be submitted to the department within ten days
				after it is requested.
(8) No
				person shall use a wood-waste burner for the burning of other than production
				process wood-waste transported to the burner by continuous flow conveying
				methods.
(9) Rubber products,
				asphaltic materials, or other prohibited materials specified in ARM
				17.8.604(1) (b) through (d), (f) through (r), (t),
				(u), (w) and (y) may not be burned or
				disposed of in wood-waste burners.
