In addition to the general applicability of chapters 173-400
and 173-490 WAC to all emission sources; no incinerator facility shall cause or
permit air contaminant emissions in excess of the limits listed below. Specific
emission standards listed in this chapter will take precedence over the general
emission standards of chapter 173-400 WAC.
(1) Particulate.
(a) For incinerator facilities that are
capable of burning two hundred fifty or more tons of solid waste per day,
emissions from each stack shall not exceed 0.046 grams of particulate per dry
cubic meter at standards conditions (0.020 grains/dscf) corrected to seven
percent oxygen for an hourly average.
(b) For incinerator facilities that have a
maximum capability of burning less than two hundred fifty tons of solid waste
per day, emissions from each stack shall not exceed 0.069 grams of particulate
per dry cubic meter at standards conditions (0.030 grains/dscf) corrected to
seven percent oxygen for an hourly average.
(2) Hydrogen chloride. The hydrogen chloride
emissions from each stack shall not exceed fifty ppm on a volumetric dry basis
corrected to seven percent oxygen for an hourly average, except if the owner or
operator demonstrates that uncontrolled emissions of hydrogen chloride are
reduced by at least eighty percent and a procedure acceptable to ecology or the
authority for monitoring is developed.
(3) Sulfur dioxide. The sulfur dioxide
emissions from each stack shall not exceed fifty ppm on a volumetric dry basis
corrected to seven percent oxygen for an hourly average, except if the owner or
operator demonstrates that the uncontrolled emissions of sulfur dioxide are
reduced by at least eighty percent and a procedure acceptable to ecology or the
authority for monitoring is developed.
(4) Opacity.
(a) The opacity as measured visually from any
incinerator stack shall not exceed an average of five percent opacity for more
than six consecutive minutes in any sixty minute period.
(b) The opacity as measured by a
transmissometer shall not exceed an average of ten percent opacity for more
than six consecutive minutes in any sixty minute period.
(c) The opacity as measured visually shall
not exceed an average of zero percent from any emissions unit except
incinerator stacks for more than six consecutive minutes in any sixty minute
period.
(5) Fugitive
emissions. Each operator or owner shall take reasonable precautions to prevent
fugitive emissions which includes the paving of all normally traveled roadways
within the plant boundary and enclosing or hooding material transfer
points.
(6) Source testing. To
demonstrate compliance with this chapter, refer to WAC
173-400-105.
