Ariz. Admin. Code § R18-2-703 - Standards of Performance for Existing Fossil-fuel Fired Steam Generators and General Fuel-burning Equipment
A. This Section applies to the following:
1. Installations 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
R18-2-704.
2. All fossil-fuel fired steam generating
units or general fuel burning equipment which are greater than or equal to 73
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
R18-2-311 . 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
4200 million Btu per hour or less, the maximum allowable emissions shall be
determined by the following equation:
E = 1.02Q0.769
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 4200 million Btu per hour, the maximum allowable emissions shall
be determined by the following equation:
E = 17.0Q0.432
where "E" and "Q" have the same meaning as in subsection (C)(1).
D. Actual values shall be
calculated from the applicable equations and rounded off to two decimal
places.
E. When low sulfur oil is
fired:
1. Existing fuel-burning equipment or
steam-power generating installations which commenced construction or a major
modification prior to May 30, 1972, shall not emit more than 1.0 pounds sulfur
dioxide maximum three-hour average, per million Btu (430 nanograms per joule)
heat input.
2. Existing
fuel-burning equipment or steam-power generating installations which commenced
construction or a major modification after May 30, 1972, shall not emit more
than 0.80 pounds of sulfur dioxide maximum three-hour average per million Btu
(340 nanograms per joule) heat input.
F. 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 (946
nanograms per joule) heat input.
G.
When solid fuel is fired:
1. Existing general
fuel-burning equipment and steam-power generating installations which commenced
construction or a major modification prior to May 30, 1972, shall not emit more
than 1.0 pounds of sulfur dioxide maximum three-hour average, per million Btu
(430 nanograms per joule) heat input.
2. Existing general fuel-burning equipment
and steam-power generating installations which commenced construction or a
major modification after May 30, 1972, shall not emit more than 0.80 pounds of
sulfur dioxide, maximum three-hour average, per million Btu (340 nanograms per
joule) heat input.
H.
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 Director 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 ensure that the sulfur dioxide ambient air quality
standards set forth in
R18-2-202 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 Department monthly reports
detailing its efforts to obtain low sulfur oil.
3. When the conditions justifying the use of
high sulfur oil no longer exists, 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.
I. Existing steam-power generating
installations which commenced construction or a major modification 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.
J. Emission and fuel monitoring systems,
where deemed necessary by the Director for sources subject to the provisions of
this Section shall, conform to the requirements of
R18-2-313.
K. 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). All tests shall
be run at the heat input calculated under subsection (B).
