distillate fuel oil used by the process emission source must not exceed 15 ppm;
and
3) The owner or operator must:

fuel oil used by the process emission source complies with the requirements in
subsections (a)(1) and (a)(2), such as records from the fuel supplier
indicating the sulfur content of the fuel oil;

intended for sale outside of Illinois. This exemption is limited to a combined
total of 150,000 gallons of distillate fuel oil per calendar year. The sulfur
content of the fuel oil must not exceed 500 ppm. The owner or operator of the
process emission sources described in this subsection must also comply with the
following:
1) Maintain records indicating the
amount of distillate fuel oil used by the process emission sources each
calendar year for purposes of research and development or testing of equipment
for sale outside of Illinois, as well as records demonstrating that the fuel
oil complies with the requirements in this subsection (b), such as records from
the fuel supplier indicating the sulfur content of the fuel oil;
2) 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

demonstrating that the distillate fuel oil purchased on and after January 1,
2016, for use by the process emission sources, complies with the requirements
in subsection (c)(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 process emission sources, complies with the
requirements in subsection (c)(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 (c) for at least 5 years, and provide copies of the records to the

the deviations, any corrective actions taken, and any preventative measures
taken.
d) The
sulfur content limitation for distillate fuel oil in subsection (a)(2) does not
apply to existing electric generating units at Midwest Generation's Fisk

operator of these 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 these 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 these 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 these 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 (d)(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 (d)(2),
