Current through Register Vol. 48, No. 38, September 20, 2024
a)
Prior to January 1, 2017, no person shall cause or allow the emission of sulfur
dioxide into the atmosphere in any one hour period from any existing fuel
combustion emission source, burning liquid fuel exclusively, to exceed the
following:
1)
1.55
kg of sulfur dioxide per MW-hr of actual heat input when residual fuel oil is
burned (1.0 lbs/mmBtu); and
2)0.46
kg of sulfur dioxide per MW-hr of actual heat input when distillate fuel oil is
burned (0.3 lbs/mmBtu).
b) Except as provided in subsections (c) and
(d), on and after January 1, 2017, the owner or operator of an existing fuel
combustion emission source, burning liquid fuel exclusively, must comply with
the following:
1) The sulfur content of all
residual fuel oil used by the fuel combustion emission source must not exceed
1000 ppm;
2) The sulfur content of
all distillate fuel oil used by the fuel combustion emission source must not
exceed 15 ppm; and
3) The owner or
operator must:
A) Maintain records
demonstrating that the fuel oil used by the fuel combustion emission source
complies with the requirements in subsections (b)(1) and (b)(2), such as
records from the fuel supplier indicating the sulfur content of the fuel
oil;
B) Retain the records for at
least 5 years, and provide copies of the records to the Agency within 30 days
after receipt of a request by the Agency; and
C) Notify the Agency within 30 days after
discovery of deviations from any of the requirements in this subsection (b). At
minimum, and in addition to any permitting obligations, the notification must
include a description of the deviations, a discussion of the possible cause of
the deviations, any corrective actions taken, and any preventative measures
taken.
c) The
sulfur content limitation for distillate fuel oil in subsection (b)(2) does not
apply to existing electric generating units at Midwest Generation's Joliet
station (located at or near 1800 Channahon Road, Joliet IL), Powerton station
(located at or near 13082 E. Manito Road, Pekin IL), Waukegan station (located
at or near 401 E. Greenwood Avenue, Waukegan IL), and Will County station
(located at or near 529 E. 135th, Romeoville IL).
The owner or operator of such electric generating units must instead comply
with the following:
1) From January 1, 2016
through December 31, 2018, the sulfur content of all distillate fuel oil
purchased for use by such electric generating units must not exceed 15
ppm;
2) From January 1, 2017
through December 31, 2018, the sulfur content of all distillate fuel oil used
by such electric generating units must not exceed 500 ppm;
3) On and after January 1, 2019, the sulfur
content of all distillate fuel oil used by such electric generating units must
not exceed 15 ppm;
4) The owner or
operator must:
A) Maintain records
demonstrating that the distillate fuel oil purchased from January 1, 2016
through December 31, 2018 for use by the electric generating units complies
with the requirements in subsection (c)(1), such as records from the fuel
supplier indicating the sulfur content of the fuel oil, and maintain records
indicating the date of purchase of the fuel oil;
B) Maintain records demonstrating that the
distillate fuel oil used from January 1, 2017 through December 31, 2018, by the
electric generating units, complies with the requirements in subsection (c)(2),
such as records from the fuel supplier indicating the sulfur content of the
fuel oil;
C) On and after January
1, 2019, maintain records demonstrating that the distillate fuel oil used by
the electric generating units complies with the requirements in subsection
(c)(3), such as records from the fuel supplier indicating the sulfur content of
the fuel oil;
D) Retain all records
required by this subsection (c) for at least 5 years, and provide copies of the
records to the Agency within 30 days after receipt of a request by the Agency;
and
E) Notify the Agency within 30
days after discovery of deviations from any of the requirements in this
subsection (c). At minimum, and in addition to any permitting obligations, the
notification must include a description of the deviations, a discussion of the
possible cause of the deviations, any corrective actions taken, and any
preventative measures taken.
d) The sulfur content limitation for
distillate fuel oil in subsection (b)(2) does not apply to existing fuel
combustion emission sources at Caterpillar's Montgomery facility (located at or
near 325 South Route 31, Montgomery IL). The owner or operator of the fuel
combustion emission sources must instead comply with the following:
1) On and after January 1, 2016:
A) The sulfur content of all distillate fuel
oil purchased for use by the fuel combustion emission sources must not exceed
15 ppm; and
B) The sulfur content
of all distillate fuel oil used by the fuel combustion emission sources must
not exceed 500 ppm;
2)
The owner or operator must:
A) Maintain
records demonstrating that the distillate fuel oil purchased on and after
January 1, 2016 for use by the fuel combustion emission sources complies with
the requirements in subsection (d)(1)(A), such as records from the fuel
supplier indicating the sulfur content of the fuel oil, and maintain records
indicating the date of purchase of the fuel oil;
B) Maintain records demonstrating that the
distillate fuel oil used on and after January 1, 2016 by the fuel combustion
emission sources complies with the requirements in subsection (d)(1)(B), such
as records from the fuel supplier indicating the sulfur content of the fuel
oil;
C) Retain all records required
by this subsection (d) for at least 5 years, and provide copies of the records
to the Agency within 30 days after receipt of a request by the Agency;
and
D) Notify the Agency within 30
days after discovery of deviations from any of the requirements in this
