(1) Fuel Burning
Installation in Operation Prior to April 3, 1972.
(a) The owner or operator of a fuel burning
installation shall not cause, suffer, allow, or permit the emissions from that
source of sulfur dioxide in excess of that contained in Table 1:

Allowable Sulfur Dioxide Emissions in
lbs.
SO2/106 BTU
X = Heat input from coal
Y = Heat input from No. 5 or No. 6 fuel oil and solid fuels
other than coal
Z = Heat input from all other fuel
(c) For purpose of this rule, the total heat
input (based on maximum rated capacity) from all fuel combustion units at a
plant, premises, or installation shall be used for determining the maximum
allowable emission of sulfur dioxide that passes through a stack or stacks. The
heat value of the fuel that is not released within the fuel burning equipment
shall not be considered as part of the heat input to the fuel burning
installation.
(d) Fuel burning
installations containing units of fuel burning equipment larger than 600
million BTU per hour heat input and which were commenced before April 3, 1972
shall comply with the applicable sulfur dioxide emission limit specified in
Table 1 or Table 2 for fuel burning installations greater than 1 billion BTU
per hour heat input. However, for fuel burning installations containing fuel
burning equipment meeting these requirements, a 24-hour averaging basis shall
be utilized rather than a one hour basis. For units of fuel burning equipment
in a fuel burning installation of less than 600 million BTU per hour heat
input, the allowable sulfur dioxide emission limits shall be those determined
by Table 1 or Table 2 of Rule 1200-14-.02(1)(a) or (1)(b).
(2) Fuel Burning Equipment Constructed After
April 3, 1972.
(a) Fuel burning equipment
with a rated capacity of 250 million BTU per hour or less heat input, shall not
cause, suffer, allow, or permit the emission of sulfur dioxide in excess of 1.6
pounds per million BTU heat input (one hour average) in a Class I county, 2.4
pounds in a Class III county, 4.0 pounds in a Class V county, nor in excess of
5.0 pounds per million BTU heat input (one hour average) in a Class II, VI, or
VII county. Emission limits for Class IV counties shall be those listed in
Table 2.
(b) The owner or operator
of fuel burning equipment with a rated capacity greater than 250 million BTU
per hour heat input shall not cause, suffer, allow, or permit the emissions
from that source of sulfur dioxide in excess of the following:
1. 80 lbs. per million BTU heat input,
maximum 1 hour average, when liquid fossil fuel is burned.
2. 1.2 lbs. per million BTU heat input,
maximum 1 hour average, when solid fossil fuel is burned.
3. Where different fossil fuels are burned
simultaneously in any combustion, the applicable standard shall be determined
by proration. Compliance shall be determined by using the following formula:
Y (0.80) + Z (1.2)
Y + Z
(c) Where:
1. Y is the percent of total heat input
derived from liquid fossil fuel and,
2. Z is the percent of total heat input
derived from solid fossil fuel.
(3) Limiting the Effect of the Definition of
Modification. If an owner or operator of fuel burning equipment is ordered by
the U.S. Department of Energy under the Energy Supply and Environmental
Coordination Act of 1974, or any amendments thereto, or any subsequent
enactment which supersedes such provisions, to switch fuels, required
alterations to existing fuel burning equipment to accommodate these additional
fuels shall not be deemed a modification for purposes of determining the
allowable emissions as established by this rule.
(4) Fuel Burning Equipment relocated after
November 6, 1988.
Irrespective of the maximum allowable emission as determined
in the preceding paragraphs in this rule, the maximum allowable sulfur dioxide
emissions for non-portable fuel burning equipment which is relocated more than
1.0 km from the previous position after November 6, 1988, shall not exceed the
greater of the actual emissions at its previous location or the allowable
emissions for new fuel burning equipment.
