35 Ill. Adm. Code 205.330
Emissions Determination Methods
Section 205
Section 205.330 Emissions
Determination Methods
The owner or operator of a
participating source or new participating source shall determine VOM emissions
from the source during the seasonal allotment period using methods as necessary
to demonstrate compliance with this Part. Such methods shall be, at a minimum,
as stringent as those required by any applicable requirement and any permit
condition. The Agency shall establish the emissions determination methods
applicable to each such source in the source's CAAPP permit or FESOP. The
following methods, in conjunction with relevant source-specific throughput and
operating data, are acceptable methods a source may use to determine seasonal
emissions, depending on the type of emission unit:
a) Material balance calculation, based on the VOM content of raw
materials and recovered materials, as is typically used for degreasers, coating
lines, and printing lines equipped with a carbon adsorption system
(recovery-type control device) or without any control device;
b) A standard engineering formula for estimation of emissions, as
is typically used for storage and transfer of volatile organic liquids;
c) A source-specific emission factor(s), based on representative
testing and sampling data and appropriate analysis, as typically used for
petroleum refining processes;
d) A published USEPA emission factor(s), as is typically used for
component leaks;
e) A source-specific emission rate or VOM control efficiency,
based on representative testing, as is typically used for chemical processes
and afterburners (destruction-type control device), respectively;
f) A method not listed above that is sufficient to demonstrate
compliance with this Section; or
g) An appropriate combination of the above methods, as typically
used for a coating or printing line equipped with a control device, where the
available emissions are determined by material balance and the control
efficiency is determined by representative testing.
