                         UNPUBLISHED OPINION

BJORKMAN, Judge

       Relators challenge respondent commission’s approval of respondent power

company’s mercury-emissions-reduction plan, arguing that the commission erred by

approving the plan without the required environmental analysis. We affirm.

                                         FACTS

       Under the Mercury Emissions Reduction Act (MERA), Minn. Stat. §§ 216B.68-

.688 (2012), a public utility that owns a large coal-fired power plant in Minnesota must

prepare a plan for reducing the plant’s mercury emissions and submit the plan to

respondent Minnesota Public Utilities Commission (MPUC) for approval. There are six

such existing plants, including respondent Minnesota Power’s Boswell 4 facility.

       On August 31, 2012, Minnesota Power filed a petition under Minn. Stat.

§ 216B.6851, seeking approval of its mercury-emissions-reduction plan for Boswell 4.

Minnesota Power proposed a four-year project to retrofit Boswell 4 with a semi-dry flue-

gas desulfurization system, fabric filter, and powder-activated carbon-injection system,

asserting that these measures would reduce the plant’s mercury emissions by 90%, reduce

the output of multiple other pollutants, and reduce plant wastewater. Minnesota Power

also detailed its process of identifying and evaluating various approaches to reducing

emissions of mercury and other pollutants, from a range of carbon-injection retrofit

options to retiring Boswell 4 in favor of a natural-gas replacement.

       The Minnesota Pollution Control Agency (MPCA) reviewed Minnesota Power’s

retrofit plan. The MPCA determined that the plan presents a technically feasible, cost-

                                             2
effective means of providing multiple environmental and public-health benefits,

including 90% reduction in mercury emissions.           The MPCA also observed that

Minnesota Power described “alternatives to mercury controls that included replacing the

entire unit with natural gas-fired generation,” but it did not evaluate the environmental

effects of a natural-gas replacement. The MPCA recommended that the MPUC approve

the retrofit plan.

       After two rounds of comments on the plan—including joint comments from

relators Minnesota Center for Environmental Advocacy, Izaak Walton League of

America–Midwest Office, Fresh Energy, and Sierra Club—and a public hearing, the

MPUC approved Minnesota Power’s retrofit plan.                  Relators petitioned for

reconsideration, which the MPUC denied. Relators appeal.

                                     DECISION

       The MPUC’s approval of a mercury-emissions-reduction plan is subject to appeal

under the Minnesota Administrative Procedure Act. See Minn. Stat. § 216B.52, subd. 1

(2012); In re N. States Power Co., 775 N.W.2d 652, 655-56 (Minn. App. 2009). Under

the act, we may affirm the MPUC’s decision, remand the case for further proceedings, or

reverse or modify the decision if the petitioner’s substantial rights have been prejudiced

because the findings, inferences, conclusions, or decision are affected by an error of law,

unsupported by substantial evidence, or are arbitrary and capricious. Minn. Stat. § 14.69

(2012).

       Relators argue that the MPUC committed legal error by approving Minnesota

Power’s retrofit plan in the absence of the full environmental assessment MERA requires.

                                            3
This argument presents a question of statutory interpretation. While we defer to an

administrative agency on matters within its field of expertise, we do not defer to an

agency’s statutory interpretation when statutory language “is clear and capable of

understanding.” In re Annandale NPDES/SDS Permit Issuance, 731 N.W.2d 502, 511,

513 (Minn. 2007). Instead, we effectuate the intent of the legislature by interpreting the

text of the statute according to its plain language. Minn. Transitions Charter Sch. v.

Comm’r of Minn. Dep’t of Educ., 844 N.W.2d 223, 227 (Minn. App. 2014), review

denied (Minn. May 28, 2014). This includes consideration of the statute “as a whole,”

accounting for the context of the surrounding words and sentences. In re Minn. Power,

838 N.W.2d 747, 754 (Minn. 2013).

       When a public utility submits a mercury-emissions-reduction plan for approval

under MERA, the MPCA is required to “evaluate” the plan and submit its evaluation to

the MPUC. Minn. Stat. § 216B.684. In doing so, the MPCA must

              (1) assess whether the utility’s plan meets the requirements of
              [Minn. Stat. § 216B.6851], (2) evaluate the environmental
              and public health benefits of each option proposed or
              considered by the utility, including benefits associated with
              reductions in pollutants other than mercury, (3) assess the
              technical feasibility and cost-effectiveness of technologies
              proposed or considered by the utility for achieving mercury
              emissions reduction, and (4) advise the commission of the
              appropriateness of the utility’s plan.

Id. The MPCA may “request additional information from the utility, especially with

regard to alternative technologies or configurations applicable to the specific unit, and the

estimated costs of those alternatives.” Id.

                                              4
      Relators argue that the natural-gas-replacement alternative that Minnesota Power

mentioned in its petition is an “option” that the MPCA was required to evaluate, and that

the MPUC could not approve the retrofit plan without that evaluation. We disagree.

      An “option” is something that is “available as a choice.” American Heritage

Dictionary 1238 (5th ed. 2011). The broader context of MERA defines whether a

particular mercury-emissions-reduction measure is “available as a choice” and therefore

requires MPCA assessment. MERA requires public utilities to reduce mercury emissions

at existing coal-fired power plants. See Minn. Stat. § 216B.68, subd. 8 (defining a

“targeted unit” as a “coal-fired electric generation unit”); see also Minn. Stat.

§§ 216B.682, subd. 1(a) (requiring utility to file a plan “for mercury emissions reduction

at each such unit”), .6851, subd. 3 (requiring plan “to achieve total mercury reduction at

targeted and supplemental units”). It does not mention retiring or repowering those

plants as a means of reducing their emissions of mercury or any other pollutant. 1 Instead,

MERA expressly anticipates that these reductions will be accomplished by installing

pollution-control equipment at those plants.      See Minn. Stat. §§ 216B.68, subd. 7

(referring to “mercury-control equipment” being “installed at a targeted unit”), .686,

subd. 1 (referring to “pollution control equipment” being “installed at facilities in

1
  The only mention in MERA of retiring or repowering coal-fired power plants is in the
narrow provision (undisputedly applicable only to Minnesota Power) that permits a utility
with two wet-scrubbed coal-fired power plants to stagger submission of mercury-
emissions-reduction plans but requires multi-faceted annual reports on the second plant,
including an assessment of whether state or federal pollution controls might warrant
“retiring or repowering” that plant, rather than installing mercury-emissions-reduction
technology. See Minn. Stat. § 216B.6851, subd. 5(b)(2)(iii).

                                            5
Minnesota”).    In short, the plain language of MERA indicates that the legislature

intended to regulate, not replace, coal-fired power plants.2

       Replacing a coal-fired plant with a facility that uses a cleaner fuel source might be

a viable pollution-control measure. But it is an alternative to regulation under MERA,

not an “option” in a mercury-emissions-reduction plan that the MPCA is required to

evaluate. Accordingly, we conclude that the MPCA did not violate its statutory duty

under section 216B.684 by declining to substantively assess the prospect of retiring and

replacing Boswell 4 with a natural-gas facility.

       Moreover, any deficiency occasioned by the MPCA’s failure to evaluate the

environmental effects of a natural-gas replacement is harmless.           Under MERA, the

MPUC’s authority to do anything other than approve a utility’s preferred plan is limited.

The MPUC “shall approve a utility’s mercury emissions-reduction plan that [the MPUC]

reasonably expects will come closest to achieving” the 90 percent goal “in a manner that

provides for increased environmental and public health benefits without imposing

excessive costs on the utility’s customers.” Minn. Stat. § 216B.6851, subd. 6(b). Only if

the MPUC is “unable” to approve the utility’s preferred plan (the “90 percent reduction

plan filed under subdivision 3”) may it order the utility to implement some other plan. Id.

       The MPCA thoroughly evaluated Minnesota Power’s retrofit plan, including its

environmental and public-health benefits, technical feasibility, and cost-effectiveness.

The MPUC considered that evaluation and the substantial evidentiary record and

  Indeed, if a utility were to retire its coal-fired power plant, it would no longer be subject
to MERA.

                                              6
determined that the retrofit plan achieves MERA’s 90% goal, provides for increased

environmental and public-health benefits, and does not impose excessive costs on

Minnesota Power’s customers. Relators do not challenge the sufficiency of the MPCA’s

review of the retrofit plan or any of the MPUC’s findings as to its effectiveness, benefits,

or costs. Under these circumstances, the MPUC was not only permitted but required to

approve the retrofit plan. Accordingly, we conclude that the MPUC did not commit legal

error by approving Minnesota Power’s retrofit plan.
