Sec. 60.1795  May I conduct stack testing less often?

    (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 subpart. 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 subpart at 
your plant. Each year, test a different municipal waste combustion unit 
subject to this subpart and test all municipal waste combustion units 
subject to this subpart in a sequence that you determine. Once you 
determine a testing sequence, it must not be changed without approval by 
the Administrator.
    (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 
subpart 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 subpart at your 
plant. You may return to testing one municipal waste combustion unit 
subject to this subpart 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 subpart for 2 
consecutive years.
