Universal Citation: 35 IL Admin Code ยง 218.183
Current through Register Vol. 48, No. 38, September 20, 2024
a) Operating Requirements: No person shall operate an open top vapor degreaser unless:
1) The cover of the degreaser is
closed when workloads are not being processed through the degreaser;
2) Solvent carry out emissions are minimized
by:
A) Racking parts to allow complete
drainage;
B) Moving parts in and
out of the degreaser at less than 3.3 m/min (11 ft/min);
C) Holding the parts in the vapor zone until
condensation ceases;
D) Tipping out
any pools of solvent on the cleaned parts before removal from the vapor zone;
and
E) Allowing parts to dry within
the degreaser until visually dry;
3) Porous or absorbent materials, such as
cloth, leather, wood or rope, are not degreased;
4) Less than half of the degreaser's open top
area is occupied with a workload;
5) The degreaser is not loaded to the point
where the vapor level would drop more than 10 cm (4 in) when the workload is
removed from the vapor zone;
6)
Spraying is done below the vapor level only;
7) Solvent leaks are repaired
immediately;
8) Waste solvent is
stored in covered containers only and not disposed of in such a manner that
more than 20% of the waste solvent (by weight) is allowed to evaporate into the
atmosphere;
9) Water is not
visually detectable in solvent exiting from the water separator; and
10) Exhaust ventilation exceeding 20 cubic
meters per minute per square meter (65 cubic feet per minute per square foot)
of degreaser open area is not used, unless necessary to meet the requirements
of the Occupational Safety and Health Act ( 29 U.S.C. Section 651 et
seq.).
b) Equipment Requirements: No person shall operate an open top vapor degreaser unless:
1) The degreaser is equipped with a cover
designed to open and close easily without disturbing the vapor zone;
2) The degreaser is equipped with the
following switches:
A) One which shuts off
the sump heat if the amount of condenser coolant is not sufficient to maintain
the designed vapor level; and
B)
One which shuts off the spray pump if the vapor level drops more than 10 cm (4
in) below the bottom condenser coil; and
C) One which shuts off the sump heat source
when the vapor level exceeds the design level;
3) A permanent conspicuous label summarizing
the operating procedure is affixed to the degreaser;
4) The degreaser is equipped with one of the
following devices:
A) A freeboard height of
3/4 of the inside width of the degreaser tank or 91 cm (36 in), whichever is
less; and if the degreaser opening is greater than 1 square meter (10.8 square
feet), a powered or mechanically assisted cover; or
B) Any other equipment or system of
equivalent emission control as approved by the Agency and further processed
consistent with Section
218.108
of this Part. Such equipment or system may include a refrigerated chiller, an
enclosed design or a carbon adsorption system.
