Title 173 - Ecology, Department of (See also Titles 197, 317, 372, and 508)
Chapter 173-490 - Emission standards and controls for sources emitting volatile organic compounds (VOC)
Section 173-490-207 - Surface coating of flatwood paneling
Universal Citation: WA Admin Code 173-490-207
Current through Register Vol. 24-06, March 15, 2024
(1) Specific applicability.
(a) This section shall apply to all flatwood
panel manufacturers and surface finishing facilities as qualified in WAC
173-490-207(1)(b) and
(c) and
173-490-025.
(b) These chapters shall apply to all
operations and equipment that is used to apply, convey and dry (including
flashoff areas) a surface pattern or coating on the following products:
(i) Printed interior panels made of hardwood
plywood and thin particleboard;
(ii) Natural finish hardwood plywood panels;
or
(iii) Hardboard paneling with
Class II finishes.
(c)
These chapters do not apply to the manufacture of exterior siding, tileboard,
or particleboard used as a furniture component.
(2) Provisions for specific processes.
(a) The owner(s) or operator(s) of a facility
shall not emit VOCs from a coating application system in excess of:
(i) 2.9 kg per 100 square meters of coated
finished product (6.0 lb/1,000 square feet) from printed interior panels,
regardless of the number of coats applied;
(ii) 5.9 kg per 100 square meters of coated
finished product (12.0 lb/1,000 square feet) from natural finish hardwood
plywood panels, regardless of the number of coats applied; and
(iii) 4.9 kg per 100 square meters of coated
finished product (10.0 lb/1,000 square feet) from Class II finishes on
hardboard panels, regardless of the number of coats applied.
(b) The emission limits in WAC
173-490-207(2)(a)
shall be achieved by:
(i) The application of
low solvent content coating technology; or
(ii) An incineration system which oxidizes at
least ninety percent of the nonmethane VOCs entering the incinerator (VOC
measured as total combustible carbon) to carbon dioxide and water; or
(iii) An equivalent means of VOC removal. The
equivalent means must be certified by the owner(s) or operator(s) and approved
by ecology.
(c) A
capture system shall be used in conjunction with the emission control systems
in WAC 173-490-207(2)(b)(ii) and
(iii). The design and operation of the
capture system must be consistent with good engineering practice and shall be
required to provide for an overall emission reduction sufficient to meet the
emission limitation in WAC
173-490-207(2)(a).
(3) Testing and monitoring.
(a) Ecology may require the owner or operator
of a facility to demonstrate at his/her own expense compliance by the methods
of WAC 173-490-207(3)(c).
(b) The owner(s) or operator(s) of a facility
shall notify ecology at least ten days before a proposed emission certification
test so the director or a representative may observe the test.
(c) To demonstrate compliance with this
chapter, refer to WAC
173-400-105.
(d) Ecology may require monitoring of the
following parameters:
(i) Exhaust gas
temperature of all incinerators;
(ii) Temperature rise across a catalytic
incinerator bed; and
(iii)
Breakthrough of VOC on a carbon adsorption unit.
