A. This section applies to the following:
1. Sources in which fuel is burned for the primary purpose of producing power, steam, hot water, hot air or other liquids, gases or solids and in the course of doing so the products of combustion do not come into direct contact with process materials. When any products or by-products of a manufacturing process are burned for the same purpose or in conjunction with any fuel, the same maximum emission limitation shall apply, except for wood waste burners as regulated under Section 17.16.170.
2. All fossil-fuel fired steam generating units or general fuel burning equipment which are greater than or equal to seventy-three megawatts capacity.
B. For purposes of this section, the heat input shall be the aggregate heat content of all fuels whose products of combustion pass through a stack or other outlet. The heat content of solid fuel shall be determined in accordance with Section 17.11.160. Compliance tests shall be conducted during operation at the nominal rated capacity of each unit.
C. No person shall cause, allow or permit the emission of particulate matter in excess of the amounts calculated by one of the following equations:
1. For equipment having a heat input rate of four thousand two hundred million BTU per hour or less, the maximum allowable emissions shall be determined by the following equation:
E = 1.02Q 0.769
where:
E = The maximum allowable particulate emissions rate in pounds-mass per hour.
Q = The heat input in million BTU per hour.
2. For equipment having a heat input rate greater than four thousand two hundred million BTU per hour, the maximum allowable emissions shall be determined by the following equation:
E = 17.0Q 0.432
where "E" and "Q" have the same meaning as in paragraph 1 of this subsection.
D. When low sulfur oil is fired:
1. Existing fuel burning equipment or steam power generating installations which commenced construction or a major alteration prior to May 30, 1972 shall not emit more than 1.0 pound of sulfur dioxide maximum three hour average, per million BTU (four hundred thirty nanograms per joule) heat input.
2. Existing fuel burning equipment or steam power generating installations which commenced construction or a major alteration after May 30, 1972 shall not emit more than 0.80 pounds of sulfur dioxide maximum three hour average per million BTU (three hundred forty nanograms per joule) heat input.
E. When high sulfur oil is fired all existing steam power generating and general fuel burning installations which are subject to the provisions of this section shall not emit more than 2.2 pounds of sulfur dioxide maximum three-hour average per million BTU (nine hundred forty-six nanograms per joule) heat input.
F. When solid fuel is fired:
1. Existing general fuel burning equipment and steam power generating installations which commenced construction or a major alteration prior to May 30, 1972 shall not emit more than 1.0 pound of sulfur dioxide maximum three-hour average, per million BTU (four hundred thirty nanograms per joule) heat input.
2. Existing general fuel burning equipment and steam power generating installations which commenced construction or a major alteration after May 30, 1972 shall not emit more than 0.80 pounds, maximum three-hour average, per million BTU (three hundred forty nanograms per joule) heat input.
G. Any permit issued for the operation of an existing source, or any renewal or modification of such a permit, shall include a condition prohibiting the use of high sulfur oil by the permittee, unless the applicant demonstrates to the satisfaction of the control officer that sufficient quantities of low sulfur oil are not available for use by the source and that it has adequate facilities and contingency plans to insure that the sulfur dioxide ambient air quality standards set forth in Chapter 17.08, Article I will not be violated.
1. The terms of the permit may authorize the use of high sulfur oil under such conditions as are justified.
2. In cases where the permittee is authorized to use high sulfur oil it shall submit to the control officer monthly reports detailing its efforts to obtain low sulfur oil.
3. When the conditions justifying the use of high sulfur oil no longer exist, the permit shall be modified accordingly.
4. Nothing in this section shall be construed as allowing the use of a supplementary control system or other form of dispersion technology.
H. Existing steam power generating installations which commenced construction or a major alteration after May 30, 1972 shall not emit nitrogen oxides in excess of the following amounts:
1. 0.20 pounds of nitrogen oxides, maximum three-hour average, calculated as nitrogen dioxide, per million BTU heat input when gaseous fossil fuel is fired;
2. 0.30 pounds of nitrogen oxides, maximum three-hour average, calculated as nitrogen dioxide, per million BTU heat input when liquid fossil fuel is fired;
3. 0.70 pounds of nitrogen oxides, maximum three-hour average, calculated as nitrogen dioxide, per million BTU heat input when solid fossil fuel is fired.
I. Emission and fuel monitoring systems, where deemed necessary by the control officer for sources subject to the provisions of this section, shall conform to the requirements of Section 17.11.200.
J. The applicable reference methods given in the Appendices to 40 CFR 60 shall be used to determine compliance with the standards as prescribed in subsections C through G and I of this section. All tests shall be run at the heat input calculated under subsection B of this section.
