WAC 173-490-207

Surface coating of flatwood paneling.

(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.
