Universal Citation: WA Admin Code 173-490-204
Current through Register Vol. 24-06, March 15, 2024
(1) Specific applicability.
(a) This section shall
apply to all packaging rotogravure, publication rotogravure, specialty printing
operations, and flexographic printing facilities that use more than 90
megagrams (100 tons) per year of VOCs as a component of ink, for the thinning
of ink, cleaning of presses, press components and equipment; and are covered by
WAC 173-490-025.
(b) Machines that have both coating units
(apply a uniform layer of material across the entire width of a web) and
printing units (forming words, designs, and pictures) shall be included under
WAC 173-490-204 rather than WAC
173-490-040(6),
Surface coaters.
(2) Provisions for specific processes.
(a) No
owner(s) or operator(s) of a packaging rotogravure, publication rotogravure or
flexographic printing subject to this regulation and employing solvent
containing ink may operate, cause, allow or permit the operation of the
facility unless:
(i) The volatile fraction of
ink, as it is applied to the substrate, contains twenty-five percent by volume
or less of organic solvent and seventy-five percent by volume or more of
water;
(ii) The ink as it is
applied to the substrate, less water, contains sixty percent by volume or more
nonvolatile material; or
(iii) The
owner(s) or operator(s) installs and operates a system that captures at least
ninety percent by weight and;
(A) A carbon
adsorption system which reduces the volatile organic emissions from the capture
system by at least ninety percent by weight;
(B) An incineration system which oxidizes at
least ninety percent of the nonmethane VOCs (VOC measured as total combustible
carbon) to carbon dioxide and water; or
(C) An alternative VOC emission reduction
system demonstrated to have at least a ninety percent reduction efficiency,
measured across the control system, and has been approved by ecology.
(b) A collection system
shall be used with the emission controls of WAC
173-490-204(2)(a)(iii).
The design and operation of the collection system shall be consistent with good
engineering practice, and shall provide an overall reduction in the emission of
VOCs of at least:
(i) Seventy-five percent
where a publication rotogravure process is used; or
(ii) Sixty-five percent where a packaging
rotogravure process is used; or
(iii) Sixty percent where a flexographic
process is used.
(3) Testing and monitoring.
(a) To demonstrate compliance with this
chapter, refer to WAC
173-400-105.
(b) When add-on control equipment is used,
continuous monitors of the following parameters shall be installed,
periodically calibrated, and operated at all times that the associated control
equipment is operating:
(i) Exhaust gas
temperature of all incinerators;
(ii) Temperature rise across a catalytic
incinerator bed;
(iii) Breakthrough
of VOC on a carbon adsorption unit; and
(iv) Any other continuous monitoring or
recording device required by ecology.
(c) The owner or operator of a facility shall
be responsible for all expenses of monitoring required by WAC
173-490-204(3)(b).
