216B.687 MERCURY EMISSIONS REDUCTION IMPLEMENTATION, OPERATION.
    Subdivision 1. Permit conditions for mercury reductions. The agency shall establish the
mercury emissions reduction for each targeted unit included in a plan approved under section
216B.685, or where applicable, for each targeted and supplemental unit included in a plan
approved under section 216B.6851.
    Subd. 2. Enforcement by agency. (a) Except as required by federal regulation, any mercury
reduction incorporated into the permit for a targeted unit as established under a plan approved
under section 216B.685, or where applicable, for each targeted and supplemental unit included
in a plan approved under section 216B.6851, must be a state-only condition of the permit and
will not be enforced by the agency during the start-up period.
(b) After the start-up period ends, the Pollution Control Agency shall incorporate into the
permit the mercury reduction reasonably expected to be achieved at each unit or facility as an
enforceable state-only reduction. For a qualifying facility with multiple units that has one or more
units included in approved plans, the agency may establish the mercury emissions reduction for
the facility covering all targeted and supplemental units at that facility after the start-up periods
for all units have concluded, and the actual mercury emissions for the units have been determined.
In setting the reduction, the agency shall give due consideration to the results of monitoring before
implementation of the plan, the results of monitoring during the start-up period, and any factors
that may impact the performance of the unit for the next five years.
    Subd. 3. Equipment optimization required. The agency shall revise the unit's air permit
every five years to ensure optimal mercury emissions reduction by equipment installed under
an approved plan, in light of technical and operational advances made since the date of plan
approval. In revising the unit's air permit, the agency may recommend, but shall not require,
additional investments in pollution control equipment, or the removal of equipment installed
pursuant to an approved plan. The utility may seek commission review of the costs associated
with a permit requirement or request for equipment optimization proposed by the agency and,
if review is requested, the revision is not effective until approved by the commission. The
commission shall approve the revision unless the utility or other party shows that it will impose
excessive consumer costs.
