216B.682 MERCURY EMISSIONS-REDUCTION PLANS.
    Subdivision 1. Dry scrubbed units. (a) By December 31, 2007, a public utility that owns
a dry scrubbed unit at a qualifying facility shall develop and submit to the agency and the
commission a plan for mercury emissions reduction at each such unit. At each dry scrubbed unit
owned and operated by the utility, the plan must propose to employ the available technology for
mercury removal that is most likely to result in the removal of at least 90 percent of the mercury
emitted from the unit.
(b) A plan submitted under this subdivision must provide for mercury emissions reduction at
each dry scrubbed unit to be implemented by December 31, 2010. A public utility that owns two
dry scrubbed targeted units must submit a plan that provides for implementation at one unit by
December 31, 2009, and at the other unit by December 31, 2010.
    Subd. 2. Wet scrubbed units. (a) By December 31, 2009, a public utility that owns a wet
scrubbed unit at a qualifying facility shall develop and submit to the agency and the commission a
plan for mercury emissions reduction at each such unit. At each wet scrubbed unit owned by the
utility, the plan must propose to employ the available technology for mercury removal that is most
likely to result in the removal of at least 90 percent of the mercury emitted from the unit.
(b) A plan submitted under this subdivision must provide for mercury emissions reduction at
each wet scrubbed unit to be implemented by December 31, 2014.
    Subd. 3. Mercury emissions plans generally. (a) In each plan submitted under this section,
a utility shall present information assessing that plan's ability to optimize human health benefits
and achieve cost efficiencies. Each plan must provide the cost, technical feasibility, and mercury
emissions reduction expected for the utility's preferred technology option and each alternative
considered. The utility shall demonstrate that it has considered achieving the mercury emissions
reduction required under this section through multiple pollutant control technology.
(b) A plan submitted under this section may also:
(1) provide measures to reduce the cost and maximize the flexibility of each option proposed
or considered; and
(2) specify permit targets or conditions proposed by the public utility for each mercury
emission-control option proposed or considered, including, but not limited to, numeric emission
targets, percent removal expectations, emission control technology installation and operation
requirements or work practice standards, and potential changes in the performance of the mercury
emissions-reduction technology over time.
(c) The utility may submit an emissions rate rider to the commission under section 216B.683
to recover the costs associated with plans filed under this section.
