35 Ill. Adm. Code 212.705
Alternative Implementation
Section 212
Section 212.705 Alternative
Implementation
Should the Agency determine that
more than one source is a contributing source pursuant to Section 212.702 of
this Subpart, the Agency may accept controls from fewer than all of the sources
identified as culpable where greater than the required levels of control for
all culpable sources are achieved at some of the culpable sources.
a) For the purposes of this Section, an "identified
source" is a source determined to be culpable for an exceedence of the
24-hour ambient air quality standard.
b) For the purposes of this Section, a "participating
source" is another source that is also identified as culpable by the
Agency for the monitored exceedence.
c) For the purposes of this Section, "equivalent air quality
benefits" shall be determined by conducting one or more dispersion
analyses in accordance with the "Guideline on Air Quality Models
(revised)," incorporated by reference in Section 212.113 of this Part.
d) An identified source may elect to achieve compliance with the
provisions of this Subpart by obtaining equivalent air quality benefits from
PM-10 emissions reductions by a participating source as would be achieved at
the identified source, provided, however, that the PM-10 emissions reductions
to be achieved by the participating source under this Section are in addition
to any other obligation it may have under this Subpart to reduce PM-10
emissions.
e) If an identified source elects to rely on this Section to
demonstrate compliance with this Subpart, the identified source must:
1) Demonstrate to the Agency that it will achieve equivalent air
quality benefits from PM-10 emission reductions at the participating source as
would be achieved from the identified source subject to this Subpart;
2) The PM-10 emissions reductions from the participating source
that the identified source is relying upon to demonstrate compliance with this
Subpart must be reflected as federally enforceable permit conditions of the
participating source's permit;
3) The participating source implements any emissions reductions
for fugitive emissions of PM-10 within ninety (90) days after the identified
source would have been required to implement Level I or Level II measures
pursuant to this Subpart; and
4) The participating source submits a reasonable schedule for
implementation of any PM-10 emission reductions from controls on process
emission units, fuel combustion emission units, or other fugitive emissions of
PM-10 at the participating source not subject to control under Sections
212.304, 212.305, 212.306, 212.308, 212.316(a) through (e), 212.424 or 212.464,
not to exceed two (2) years from the date of notification to the identified
source that Level I or Level II measures, as appropriate, are required.
