Title 35 - ENVIRONMENTAL PROTECTION
Part 218 - ORGANIC MATERIAL EMISSION STANDARDS AND LIMITATIONS FOR THE CHICAGO AREA
Subpart DD - AEROSOL CAN FILLING
Section 218.686 - Control Requirements
Universal Citation: 35 IL Admin Code ยง 218.686
Current through Register Vol. 48, No. 38, September 20, 2024
a) Every owner or operator of an aerosol can filling line that is filling cans with a propellant which contains propane, butane or other VOM subject to this Subpart shall comply with the following requirements:
1) Emission capture and control techniques
which achieve an overall reduction in uncontrolled VOM emission of at least 81%
from the propellant filling area, also known as the gas house, on each line;
or
2) As an alternative to
compliance with subsection (a)(1) of this Subpart, the owner or operator of an
aerosol can filling line shall comply with the following requirements:
A) Fill all cans, other than trial runs of
cans to verify product quality, using through-the-valve fill or enhanced
under-the-cup fill to minimize loss of VOM propellant; or use a reclamation
system to recover surplus VOM propellant; or use another system approved in a
federally enforceable permit which achieves at least 75% reduction of the
emissions of under-the-cup fill;
B)
Fill on a monthly basis at least 90% of cans filled on such aerosol can filling
lines that are capable of being filled by the through-the-valve method with
through-the-valve fill. All cans shall be considered capable of being filled by
the through-the-valve method unless, as demonstrated by the records required by
Section
218.692(b)(2)
of this Part, the valve assembly is not adaptable to the through-the-valve
fill; through-the-valve fill cannot be accomplished with at least 85% of the
under-the-cup operating rate in cans per minute of filling; or performance,
that is the discharge of the can's contents to accomplish its intended
function, is negatively affected by through-the-valve fill considering factors
such as propellant solubility in the can's contents and the amount of
turbulence which the contents may experience during propellant filling;
and
C) Verify proper filling of
cans with a VOM monitoring system in the gas house. This system may monitor VOM
concentration as a percentage of the lower explosive limit.
b) Every owner or operator of a propellant booster pump associated with an aerosol can filling line subject to this Subpart shall comply with one of the following requirements:
1) Emission capture and control
techniques which achieve an overall reduction in uncontrolled VOM emission of
at least 81% from each pump. If the pumps are located in the gas house of a
filling line, compliance with this reduction may be achieved by the combination
of the pumps located in the gas house and the propellant filling area;
or
2) Work practices to prevent
leaks from a pump, meaning a loss of VOM from the pump above background levels.
Work practices shall include changing seals every four (4) weeks and plungers
every 16 weeks unless a pump monitoring procedure approved in a federally
enforceable permit establishes otherwise.
