Chapter 103 - FUEL BURNING EQUIPMENT PARTICULATE EMISSION STANDARD
Section 096-103-2 - Emission Standards

(a) Any coal burning source with a heat input capacity of less than 50 million BTU/Hr shall not exceed 0.30 lbs. particulate per million BTU.

(b) Any coal burning source including one presently burning oil but designed to burn coal with a heat input capacity of 50 million BTU/Hr. or greater shall not exceed 0.08 lbs. particulate per million BTU.

(a) Any source designed to burn wood, bark, chips, sawdust, pulp mill sludge or similar forest product (including those with supplementary oil firing capabilities) with a heat input capacity of less than 150 million BTU/Hr. shall not exceed an emission rate defined according to the following equation (even during periods of burning only oil):

log y = 0.034 - 0.256 log x

wherey = allowable emission rate expressed inlbs particulate per million BTU

x = equipment capacity expressed in millions of BTU`s/hour.

(b) Any source designed to burn wood, bark, chips, sawdust, pulp mill sludge or similar forest product (including those with supplementary oil firing capabilities) with a heat input capacity of 150 million BTU/Hr. or greater shall not exceed 0.30 lbs. particulate per million BTU. (even during periods of burning only oil).

(a) Any source burning distillate or residual fuel oil, gas, or other petroleum product with a heat input capacity of less than 50 million BTU/Hr. shall not exceed 0.l2 lbs particulate per million BTU.

(b) Any source burning distillate or residual fuel oil, gas, or other petroleum product with a heat input capacity of 50 million BTU/Hr. or greater but less than 250 million BTU/Hr. shall not exceed 0.08 lbs. particulate per million BTU.

(c) Any source burning distillate or residual fuel oil, gas, or other petroleum product with a heat input capacity of greater than 250 million BTU/Hr. shall not exceed 0.06 lbs. particulate per million BTU.

(a) Any source burning refuse, garbage, trash or any combination of municipal or industrial solid waste with a heat input capacity of less than 50 million BTU/Hr. shall not exceed 0.30 lbs. particulate per million BTU.

(b) Any source burning refuse, garbage, trash or any combination of municipal or industrial solid waste with a heat input capacity of 50 million BTU/Hr. or greater but less than 250 million BTU/Hr. shall not exceed 0.20 lbs. particulate per million BTU.

(c) Any source burning refuse, garbage, trash, or any combination of municipal or industrial solid waste with a heat input capacity of 250 million BTU/Hr. or greater shall not exceed 0.l0 lbs. particulate per million BTU.

(a) Any coal burning source with a heat input capacity of less than 50 million BTU/Hr. shall not exceed 0.30 lbs. particulate per million BTU.

(b) Any coal burning source with a heat input capacity equal to or greater than 50 million BTU/Hr. but less than 250 million BTU/Hr. shall not exceed 0.08 lbs. particulate per million BTU.

(c) Any coal burning source with a heat input capacity of 250 million BTU/Hr. or greater shall not exceed 0.05 lbs. particulate per million BTU.

(a) Any biomass boiler, so called, designed to burn wood, bark, coal, sludge, petroleum product or other such combustible fuel, alone or in combination, with a heat input capacity of less than 50 million BTU/Hr. shall not exceed 0.30 lbs. particulate per million BTU.

(b) Any biomass boiler, so called, designed to burn wood, bark, coal, sludge, petroleum product or other such combustible fuel, alone or in combination, with a heat input capacity of 50 million BTU/Hr. or greater but less than 250 million BTU/Hr. shall not exceed 0.08 lbs. particulate per million BTU when burning the primary fuel or fuel combinations within the range of design rate proportions. When burning a fuel other than the primary design fuel or a combination of fuels outside the range of design rate proportions the particulate emissions shall not exceed 0.l0 lbs. particulate per million BTU provided the particulate matter control equipment is being operated to maximize particulate removal.

(c) Any biomass boiler, so called, designed to burn wood, bark, coal, sludge, petroleum product or other such combustible fuel, alone or in combination, with a heat input capacity of 250 million BTU/Hr. or greater shall not exceed 0.06 lbs. particulate per million BTU when burning the primary fuel, or fuel combinations within the range of design rate proportions. When burning a fuel other than the primary design fuel, or a combination of fuels outside the range of design rate proportions, the particulate emissions shall not exceed 0.l0 lbs. particulate per million BTU, provided the control equipment is being operated and maintained to maximize particulate removal.

(d) Any biomass boiler, so called, designed to burn wood, coal, sludge, petroleum product or other such combustible fuel, alone or in combination, with a heat input capacity of 50 million BTU/Hr. or greater which uses a venturi scrubber providing 75% or greater Sulfur Dioxide removal shall be exempt from the provisions of (b) and (c) and shall not exceed 0.l0 lbs. particulate per million BTU.

NOTE: In adopting the provisions contained in this section, the Board has determined that the limitations represent Best Available Control Technology on December 22, l982 except when more stringent limitations are required under 40 CFR Part 60, New Source Performance Standards.
