control of mercury emissions from the EGU than was achieved with the
prior control technique, the owner or operator of the EGU must resume

control technique shows comparable effectiveness, the owner or operator
of the EGU may either continue to use the alternative control technique in
an optimum manner or resume use of the prior control technique. If the
evaluation of the alternative control technique shows more effective
control of mercury emissions, the owner or operator of the EGU must
continue to use the alternative control technique in an optimum manner, if
it continues to operate pursuant to this Section.
