35 Ill. Adm. Code 291.102
Purpose
Section 291
Section 291.102 Purpose
a) These rules were developed by the Agency to provide guidance
to sources that choose to show compliance with Section 9(a) of the Act or Rule
102 of the Pollution Control Board Rules and Regulations, Chapter 2: Air
Pollution (codified as 35 Ill. Adm. Code 201.141), by performing comprehensive
air quality impact evaluations.
b) These rules were formulated in response to the remand by the
Illinois Supreme Court to the Pollution Control Board (Board) of the adoption
of Rules 203(g)(1), 204(a)(1) and 204(c)(1)(A) (codified as 35 Ill. Adm. Code
212.201 through 212.205, 214.121(a) and 214.141), which established particulate
and sulfur dioxide emission standards for new and existing fuel combustion
sources. Commonwealth Edison v. Pollution Control Board, 62 Ill. 2d 494
(1976). The Court's decision, however, did not eliminate the requirement of
construction or operating permits for solid fuel emission sources; it also did
not eliminate the prohibition of air pollution contained in Section 9(a) and
Rule 102 nor the prohibition of ambient air quality violations contained in
Rule 102.
c) Thus, for any period that Rules 203(g)(1), 204(a)(1) or
204(c)(1)(A) are not effective, construction and operating permit applications
for solid fuel combustion sources will be evaluated on the basis of
comprehensive air quality impact evaluations performed by the applicant and
designed to enable the Agency to determine the status of compliance with
respect to the air quality provisions of Section 9(a) and Rule 102.
d) In lieu of performing comprehensive air quality impact
evaluations in accordance with these rules, the applicant may elect to show
compliance with the emission limitations contained in Rules 203(g)(1),
204(a)(1) and 204(c)(1)(A), even if those rules are not currently effective.
Compliance with these emissions limitations will usually be deemed by the
Agency to be sufficient to assure compliance with the air quality provisions of
Section 9(a) of the Act and Rule 102. Of course, for any period of time in
which Rules 203(g)(1), 204(a)(1) or 204(c)(1)(A) are in effect, the permit
applicant must show compliance with these rules, without regard to
comprehensive air quality analysis done pursuant to these rules. Compliance
with these rules may only be used to support permit applications when Rules
204(g)(1), 204(a)(1) or 204(c)(1)(A) are not effective.
