Cite as Mich. Admin. Code R 336.2505
Rule 1505. (1) The default baseline coal and fuel analysis for input mercury levels shall
be based on the data collected for the 1999 information collection request (ICR) as required
by and submitted to the United States environmental protection agency.
(2) The owner or operator of an affected EGU complying with this part may submit a coal
and other fuel sampling plan to determine alternative input mercury baseline levels for the
fuels burned on an annual basis. The coal and other fuel sampling plan shall include
sampling for a minimum of 12 months of operation and may include a determination for a
mercury pretreatment credit. Both of the following apply:
(a) The coal and other fuel sampling plan is subject to the review and approval of the
department. If the department determines the plan does not contain adequate sampling
methodologies, then the department may disapprove the plan, state its reasons for
disapproval, and require the affected EGU to revert to the baseline as determined under
subrule (1) of this rule.
(b) Within 180 days after the department approves a coal and other fuel sampling plan,
the owner or operator of the EGU shall implement the plan.
(3) If subrule (2) of this rule is utilized for new EGUs, the owner or operator may sample
to determine the baseline during the first 12 months after commencement of operation
provided a coal and other fuel sampling plan is submitted to the department and is
acceptable.
