Commission.

SALTER, Justice [¶1.] Crowned Ridge Wind II, LLC (Crowned Ridge) applied to the South Dakota Public Utilities Commission (the PUC) for a permit to construct a large- scale wind energy farm in northeast South Dakota. Several individuals intervened and objected to Crowned Ridge’s application. After conducting an evidentiary hearing, the PUC issued a written decision approving the application. The intervenors appealed to the circuit court, which affirmed the PUC’s decision. Six of the intervenors now appeal to this Court. We affirm.

Facts and Procedural History [¶2.] Crowned Ridge is a wind energy company that sought to construct a wind farm comprised of 132 wind turbines capable of producing 300.6 megawatts of electricity in Codington, Grant, and Deuel Counties (the Project). Under the provisions of SDCL 49-41B-2(13), Crowned Ridge’s Project was statutorily defined as a “wind energy facility” because its size and design contemplated generating “one hundred megawatts or more of electricity.” The Project also satisfied the broader statutory definition of a “facility,” which includes a wide variety of energy facilities. SDCL 49-41B-2(7). Consequently, Crowned Ridge could not begin construction of the Project without obtaining a permit from the PUC. SDCL 49-41B-4. 1 [¶3.] Crowned Ridge submitted its application for a permit on July 9, 2019. The six individuals who are the appellants in this appeal (the Intervenors) timely

1. Crowned Ridge was also required to secure the approval of the respective county zoning authorities before beginning construction on the Project. See Ehlebracht v. Deuel Cnty. Bd. of Adjustment, 2022 S.D. 18, 972 N.W.2d 464.

sought and obtained party status to oppose the issuance of a permit. 2 Each of the Intervenors are residents of Deuel County living near the Project. Their opposition to the permit was primarily based on the wind turbines’ production of ambient noise and a phenomenon known as shadow flicker, which refers to momentary disruptions of natural sunlight caused by the rotation of a wind turbine’s blades. [¶4.] Crowned Ridge did not propose to construct turbines on land owned by the Intervenors and did not enter into lease or easement agreements with them, as it had done with the other area landowners on whose property the Project was directly sited. Members of this latter group are known as participating landowners, while those in the former category, including the Intervenors, are described as non- participating landowners. [¶5.] Where, as here, an application meets with opposition, the PUC conducts a contested case hearing using the procedures set out in South Dakota’s Administrative Procedure Act contained in SDCL chapter 1-26. See SDCL 49-41B- 17.2. For Crowned Ridge’s application, the PUC conducted a hearing on February 4–6, 2020, to consider evidence and argument concerning the potential impact of the Project on the environment and surrounding communities. [¶6.] The evidentiary hearing produced extensive testimony from seventeen witnesses. Many of the witnesses had previously submitted “pre-filed” direct

2. In addition to the applicant, parties to the permit application process also include PUC staff and “[a]ny person residing in the area where the facility is proposed to be sited, or any directly interested person” who asks to intervene and obtains “party status.” SDCL 49-41B-17. The PUC ultimately granted party status as intervenors to nine individuals. Three of those individuals are not parties to this appeal.

testimony and exhibits to the PUC, detailing their views about the Project. See ARSD 20:10:22:39 (stating in part, “[u]pon the filing of an application pursuant to SDCL 49-41B-11, an applicant shall also file all data, exhibits, and related testimony which the applicant intends to submit in support of its application.”). [¶7.] For instance, Crowned Ridge submitted pre-filed direct testimony from Jay Haley, a wind energy consultant who was engaged by Crowned Ridge to conduct studies on the levels of noise and shadow flicker the Project would produce. At the evidentiary hearing itself, Haley testified that, based on the “conservative assumptions” of the sound study, the noise levels produced by the Project would fall within the applicable county guidelines of forty-five decibels measured at non- participating residences. Haley further testified that, based on the light study he conducted, the shadow flicker produced by the Project would fall within the county- imposed limits of no more than thirty hours of affected light per calendar year. 3 [¶8.] Crowned Ridge also submitted pre-filed direct testimony from Christopher Ollson, PhD. Dr. Ollson was engaged by Crowned Ridge to study the potential health implications associated with sound and shadow flicker. At the evidentiary hearing, Dr. Ollson testified that the proposed limits of forty-five decibels of sound at non-participating residences and no more than thirty hours of shadow flicker would pose “no potential health or welfare risk to the county residents.”

3. Zoning ordinances in both Grant and Deuel Counties included limitations on sound generation of forty-five decibels at non-participating residences and a shadow flicker limit of no more than thirty hours per year. The zoning ordinance for Codington County included a sound limit of fifty decibels at all residences but did not regulate shadow flicker.

[¶9.] Darren Kearney, a utility analyst employed by the PUC staff, testified about the process by which the PUC has historically regulated shadow flicker limits. During cross-examination, counsel for the Intervenors questioned Kearney about a lower shadow flicker level (fifteen hours per year) previously imposed as a condition for a different wind energy project, known as Prevailing Wind Park. 4 Kearney explained that the fifteen-hour-per-year condition was not a recommendation from the PUC staff, but was instead adopted by the commissioners after an evidentiary hearing. Kearney further testified that, in working with the permit applicants, the PUC staff commonly deferred to county regulations setting the maximum amount of shadow flicker and incorporated those limits into the permit conditions. He stated the “there are no [PUC] regulations. It’s a case-by- case basis.” [¶10.] The PUC staff also submitted pre-filed direct testimony from acoustical engineer David Hessler who was engaged to review the noise study conducted by Jay Haley. During cross-examination at the evidentiary hearing, Hessler testified that the Project was “aggressively devised” by Crowned Ridge “in the sense of they’re trying to put a lot of turbines into the project area.” Hessler stated that Crowned Ridge had accommodated his requests to move certain turbines to alternate locations in an attempt to mitigate sound emissions. Nevertheless, Crowned Ridge was unable to achieve projected noise levels below forty decibels, which Hessler described as the ideal noise limit. In his view, “annoyance and
