Section 1200-03-06-.05 - WOOD-FIRED FUEL BURNING EQUIPMENT(1) Any wood fired-fuel burning equipment commenced before March 1, 1978, must comply with the following emission standards shown below: (a) 0.330 grains of particulate matter per standard dry cubic foot of exhaust gasses, corrected to 12% carbon dioxide, for fuel burning equipment up to and including 50 million Btu per hour heat input.(b) 0.300 grains of particulate matter per standard dry cubic foot of exhaust gasses, corrected to 12% carbon dioxide, for fuel burning equipment of 100 million Btu per hour heat input or in excess thereof.(c) The allowable emissions for wood-fired fuel burning equipment between 50 million and 100 million Btu per hour heat input is that determined by linear interpolation between the values in subparagraphs (a) and (b).(d) 0.56 grains of particulate matter per dry standard cubic foot of exhaust gases, corrected to 12% carbon dioxide, for fuel burning equipment up to and including 50 million Btu per hour heat input for counties identified in paragraph (8)(d) of this rule.(e) The allowable for wood-fired fuel burning equipment between 50 million and 100 million Btu per hour heat input is that determined by linear interpolation between the values in subparagraph (d) and (b) for counties identified in paragraph (8)(d) of this rule.(2) Any wood-fired fuel burning equipment commenced on or after March 1, 1978, must comply with the emission standards shown below:(a) 0.330 grains of particulate matter per standard dry cubic foot of exhaust gasses, corrected to 12% carbon dioxide, for fuel burning equipment up to, and including, 25 million Btu per hour heat input.(b) 0.200 grains of particulate matter per standard dry cubic foot of exhaust gasses, corrected to 12% carbon dioxide, for fuel burning equipment of 100 million Btu per hour heat input or in excess thereof.(c) The allowable emissions for wood-fired fuel burning equipment between 25 million and 100 million Btu per hour heat input is that determined by linear interpolation between the values in subparagraphs (a) and (b).(3) Wood as used in this rule means: (b) Sawdust or other woody plant tissues (lignified xylem) mechanically reduced in size, but not chemically changed.(c) Any combination of the materials in (a) and (b).(4) Any fuel burning installation with wood-fired burning equipment such that said wood-fired fuel burning equipment has 100 million Btu heat input per hour or in excess thereof, shall install, calibrate, maintain, and operate a photoelectric or any other type opacity monitor and recorder that has been approved by the Technical Secretary and is of the type referred to in Rule 1200-3-5-.05. This paragraph does not apply where the moisture content of the exhaust is so high that condensation occurs in the stack.(5) This rule only applies to that fuel burning designed to burn wood and when the burning of wood provides at least 30% of the heat input of the unit. At other times the unit will revert to being regulated by Rule 1200-03-06-.02. This rule 1200-03-06-.05 does not apply to units burning coal or liquid fuels other than fuel oils.(6) Where fuel burning equipment units are the same fuel burning installation are subject to this rule and are regulated by two different grain loading limits, an average weighted directly on the flow rates will determine the allowable emission limit.(7) When a wood-fired fuel burning equipment is on a common stack with other air contaminant sources, then the wood-fired units shall be considered independent of the other air contaminant sources.(8) The applicability of this rule shall be as follows: (a) Paragraph (2) of this rule shall apply to all wood-fired fuel burning equipment commenced on or after March 1, 1978, except for those units in Davidson, Hamilton, Knox, and Shelby counties.(b) Subparagraphs (1)(a) and (1)(c) of this rule shall apply to all wood-fired fuel burning equipment commenced before March 1, 1978 in Madison, Bedford, Hamblen, and Coffee counties.(c) Subparagraph (1)(b) of this rule shall apply to wood fired-fuel burning equipment commenced before March 1, 1978 except for units in Davidson, Hamilton, Knox, and Shelby counties.(d) Subparagraphs (1)(d) and (1)(e) of this rule shall apply to all wood fired fuel burning equipment commenced before March 1, 1978 in Bradley, Claiborne, Cocke, Cumberland, Dickson, Fentress, Franklin, Gibson, Giles, Grainger, Greene, Henry, Jefferson, Lawrence, Loudon, Macon, Marion, Marshall, McMinn, Montgomery, Polk, Putnam, Rhea, Rutherford, Scott, Sevier, Sumner, Warren, Wayne, Weakley, White, Williamson, and Wilson counties whose emissions have been strategy tested and included in the State Implementation Plan. Any wood fired fuel burning equipment which except for not having had its emissions strategy tested and included in the State Implementation Plan would be wood fired fuel burning equipment designated by the preceding sentence of this subparagraph shall be regulated by subparagraph (1)(a), (b), or (c) of this rule.(9) Except as mentioned in paragraph (8) of this rule, all existing wood-fired fuel burning equipment of 50 million Btu per hour heat input or less shall be regulated by Rule 1200-03-06-.02.Tenn.
