(i) | Clear coatings | 0.52 kg/liter | (4.3 lb/gallon) |
(ii) | Extreme performance coatings | 0.42 kg/liter | (3.5 lb/gallon) |
(iii) | Air dried coatings | 0.42 kg/liter | (3.5 lb/gallon) |
(iv) | All others | 0.36 kg/liter | (3.0 lb/gallon) |
(v) | Powder coatings | 0.05 kg/liter | (0.4 lb/gallon) |
(b) When more than one emission limitation listed in WAC 173-490-205 (2)(a) applies to a specific coating, the least stringent will apply.
(c) All VOC emissions from solvent washings shall be considered in the emission limitations in WAC 173-490-205 (2)(a), unless the solvent is directed into containers that prevent evaporation into the atmosphere.
(d) The emission limits set forth in WAC 173-490-205 (2)(a) shall be achieved by:
(i) The application of low solvent coating technology; or
(ii) An incineration system that oxidizes at least ninety percent of the VOCs (VOC measured as total combustible carbon) to carbon dioxide and water; or
(iii) An equivalent means of VOC reduction certified by the owner(s) or operator(s) and approved by ecology.
(e) A collection system shall be used together with the incinerator of WAC 173-490-205 (2)(d)(ii). The design and operation of the collection system shall be consistent with good engineering practice and provide for an overall VOC emission reduction necessary to comply with the emission limits of WAC 173-490-205 (2)(a). The required VOC emission reduction shall be calculated on a unit volume of uncured solids basis.
(3) Testing and monitoring.
(a) Ecology may require the owner(s) or operator(s) of a source to demonstrate at his/her own expense, compliance by the methods of WAC 173-490-205 (3)(c).
(b) The owner(s) or operator(s) of a source 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.
