Current through Reg. 49, No. 28; July 12, 2024
(a) You may test less often if you own or
					 operate a Class II municipal waste combustion unit and if all stack tests for a
					 given pollutant over 3 consecutive years show you comply with the emission
					 limit. In that case, you are not required to conduct a stack test for that
					 pollutant for the next 2 years. However, you must conduct another stack test
					 within 36 months of the anniversary date of the third consecutive stack test
					 that shows you comply with the emission limit. Thereafter, you must perform
					 stack tests every 3rd year but no later than 36 months following the previous
					 stack tests. If a stack test shows noncompliance with an emission limit, you
					 must conduct annual stack tests for that pollutant until all stack tests over 3
					 consecutive years show compliance with the emission limit for that pollutant.
					 The provision applies to all pollutants subject to stack testing requirements:
					 dioxins/furans, cadmium, lead, mercury, particulate matter, opacity, hydrogen
					 chloride, and fugitive ash.
(b) You
					 can test less often for dioxins/furans emissions if you own or operate a
					 municipal waste combustion plant that meets two conditions. First, you have
					 multiple municipal waste combustion units onsite that are subject to this
					 division. Second, all those municipal waste combustion units have demonstrated
					 levels of dioxins/furans emissions less than or equal to 15 nanograms per dry
					 standard cubic meter (total mass) for Class I units, or 30 nanograms per dry
					 standard cubic meter (total mass) for Class II units, for 2 consecutive years.
					 In that case, you may choose to conduct annual stack tests on only one
					 municipal waste combustion unit per year at your plant. The provision only
					 applies to stack testing for dioxins/furans emissions.
(1) Conduct the stack test no more than 13
					 months following a stack test on any municipal waste combustion unit subject to
					 this division at your plant. Each year, test a different municipal waste
					 combustion unit subject to this division and test all municipal waste
					 combustion units subject to this division in a sequence that you determine.
					 Once you determine a testing sequence, it must not be changed without approval
					 by the executive director.
(2) If
					 each annual stack test shows levels of dioxins/furans emissions less than or
					 equal to 15 nanograms per dry standard cubic meter (total mass) for Class I
					 units, or 30 nanograms per dry standard cubic meter (total mass) for Class II
					 units, you may continue stack tests on only one municipal waste combustion unit
					 subject to this division per year.
(3) If any annual stack test indicates levels
					 of dioxins/furans emissions greater than 15 nanograms per dry standard cubic
					 meter (total mass) for Class I units, or 30 nanograms per dry standard cubic
					 meter (total mass) for Class II units, conduct subsequent annual stack tests on
					 all municipal waste combustion units subject to this division at your plant.
					 You may return to testing one municipal waste combustion unit subject to this
					 division per year if you can demonstrate dioxins/furans emissions levels less
					 than or equal to 15 nanograms per dry standard cubic meter (total mass) for
					 Class I units, or 30 nanograms per dry standard cubic meter (total mass) for
					 Class II units, for all municipal waste combustion units at your plant subject
					 to this division for 2 consecutive years.
