Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 215 - ORGANIC MATERIAL EMISSION STANDARDS AND LIMITATIONS › Subpart F - COATING OPERATIONS › Section 215.207 - Compliance by Aggregation of Emission Units

Current through Register Vol. 48, No. 28, July 12, 2024
a) Owners or operators of coating lines
				subject to Section
				215.204
				may comply with this Section rather than with Section 215.204. The methods or
				procedures used to determine emissions of volatile organic material under this
				Section shall be approved by the Agency in accordance with 35 Ill. Adm. 201.
				Emissions of volatile organic material form sources subject to Section
				215.204
				are allowable, notwithstanding the limitations in Section 215.204, if the
				combined actual emissions from selected coating lines at the coating plant, but
				not including coating lines or other emission sources constructed or modified
				after July 1, 1979, is less than or equal to the combined allowable emissions
				as determined by the following equations:

c)
				As used in subsection (a) and (b), symbols mean the following:
EALL
=
the allowable volatile organic material emissions
							 from the coating plant in kg/day (lb/day).
Ai
=
the allowable emission limit for a coating pursuant
							 to Section
							 215.204
							 expressed in kg/1 (lbs/gal) of coating solids.
Bi
=
the volume of coating solids in 1/day (gal/day) in a
							 coating as delivered to the coating line.
m
=
the number of coating lines included in the combined
							 emission rate.
n
=
the number of different coatings delivered to a
							 coating line.
EACT
=
the actual volatile organic material emissions from
							 the coating plant in kg/day (lbs/day).
Ci
=
the weight of volatile organic material per volume of
							 solids in kg/1 (lb/gal) for a coating.
Di
=
the control efficiency by which emissions of volatile
							 organic material from a coating are reduced through the use of control
							 equipment.
Ri
=
the applicable organic material emission limit
							 pursuant to Section 215.204, for a coating in kg/1 (lb/gal).
Si
=
the density of the volatile organic material in a
							 coating in kg/l (lb/gal).
d)
				The owner or operator of the coating plant shall maintain records of the
				density of the volatile organic material in each coating, the quantity and
				volatile organic material and solids content of each coating applied and the
				line to which coating is applied, in such a manner so as to demonstrate
				continuing compliance with the combined allowable emissions.
e) Except for emission units subject to
				Section
				215.301
				or
				215.302,
				credits from emission units at the coating plant that are subject to this Part,
				other than coating lines, may be given to the extent that emissions are reduced
				from the allowable emission limits for such emission units contained in either
				this Part or any existing operating permit, whichever limit is less.
