SUPREME COURT OF OHIO

(Nos. 2022-0053 and 2022-0054—Submitted April 18, 2023—Decided October
18, 2023.)
APPEALS from the Power Siting Board, Nos. 18-1578-EL-BGN and
18-1579-EL-BGN.
____________________
DEWINE, J.
{¶ 1} This matter concerns two large solar farms proposed to be built in
Preble County. The General Assembly has authorized commercial solar farms in
Ohio but has made their construction conditional on approval by the Ohio Power
Siting Board. Before a large solar farm may be built, the board must determine that
the solar farm complies with certain statutory criteria.
{¶ 2} The board ultimately approved the two solar farms at issue. It did so
after its staff agreed to stipulations with the two solar farms, various local
governments, and the Ohio Farm Bureau. The stipulations impose a number of
conditions on the construction and operation of the facilities. In this appeal, a
citizens group and some nearby residents challenge the board’s orders approving
the facilities. The legislature has instructed that we may reverse a board order only
if we find it to be unlawful or unreasonable. Because neither has been established,
we affirm the orders of the Power Siting Board.
I. BACKGROUND
{¶ 3} In this opinion, we deal with two separate appeals. In the first case,
the board granted Alamo Solar I’s application for a certificate to build a solar-
powered electric-generation facility in Gasper and Washington Townships in
Preble County. In the second case, the board granted Angelina Solar I’s application
for a certificate to build a solar-powered electric-generation facility in Israel and
Dixon Townships in Preble County.
{¶ 4} A group called Concerned Citizens of Preble County, L.L.C., has
appealed the board’s order in each case. Certain individual members of the group

2
January Term, 2023

are also appellants in the respective cases. (This opinion will refer to all of the
appellants as “the citizens.”) In both appeals, the citizens present nearly identical
propositions of law and arguments. We consolidated the cases for oral argument,
and we now do so for purposes of this decision.
{¶ 5} Alamo and Angelina filed applications in late 2018 seeking the
board’s approval to construct their respective facilities. Each solar farm will
contain large arrays of ground-mounted solar panels, as well as support facilities
such as access roads, meteorological stations, buried electricity-collection lines,
inverter pads, and a substation. Because the solar farms will have the capacity to
generate more than 50 megawatts of electricity, they must obtain board approval
prior to construction. R.C. 4906.01(B)(1)(a) and 4906.04.
{¶ 6} In 2019, joint stipulations and recommendations were filed in each
case. The stipulations were intended to resolve all matters relevant to certification
and construction of the facilities. In each case, the stipulations were agreed to by
the applicant, board staff, the Preble County Commissioners, the Preble County
Engineer, the Preble County Planning Commission, the Preble County Soil and
Water Conservation District, and the Ohio Farm Bureau. The trustees of the
townships in which the facilities are to be located (Gasper and Washington for
Alamo, and Israel and Dixon for Angelina) also joined the respective stipulations.
The citizens did not join either stipulation.
{¶ 7} After the board conducted evidentiary hearings on both stipulations,
the parties filed amended and restated stipulations and recommendations with the
board.1 The board then held supplemental hearings in each case to consider
testimony supporting and opposing the amended stipulations.
{¶ 8} In June 2021, the board issued an opinion and order in each case
approving the amended stipulations, subject to certain conditions, and granting

1. All parties signed the amended joint stipulations except for Israel Township.

SUPREME COURT OF OHIO

certificates for the construction of the facilities. After unsuccessfully seeking
rehearing, the citizens filed an appeal in each case. Alamo and Angelina have
intervened in their respective cases and urge us to affirm the board’s orders.
II. ANALYSIS
{¶ 9} The General Assembly has established standards for the construction
of major utility facilities in Ohio and delegated to the Power Siting Board the
authority to implement those standards. Before the board may issue a certificate
for the construction of a major utility facility, it must make eight substantive
determinations. R.C. 4906.10(A). Two of the determinations are at issue in this
appeal. Specifically, “[t]he board shall not grant a certificate * * * unless it finds
and determines”:

(2) [t]he nature of the probable environmental impact;
(3) [t]hat the facility represents the minimum adverse
environmental impact, considering the state of available technology
and the nature and economics of the various alternatives, and other
pertinent considerations.

Central to the citizens’ arguments is a claim that the board misinterpreted and
misapplied its own rules by not requiring Alamo and Angelina to submit all the
information required by those rules. They contend that as a result, the board did
not have the information it needed to determine the nature of the probable
environmental impact of the proposed facilities and whether the proposed facilities
represent the minimum adverse impact.
{¶ 10} Our standard of review is prescribed by statute. We may reverse,
modify, or vacate an order of the board only when, upon consideration of the record,
we conclude that the order is “unlawful or unreasonable.” R.C. 4903.13 and
4906.12. The citizens bear the burden of establishing that the orders are unlawful

4
January Term, 2023

or unreasonable. See In re Complaint of Reynoldsburg, 134 Ohio St.3d 29, 2012-
Ohio-5270, 979 N.E.2d 1229, ¶ 18; Monongahela Power Co. v. Pub. Util. Comm.,
104 Ohio St.3d 571, 2004-Ohio-6896, 820 N.E.2d 921, ¶ 29.
{¶ 11} The term “unlawful” in the standard refers to our review of legal
questions. In re Application of Firelands Wind, L.L.C., __ Ohio St.3d __, 2023-
Ohio-2555, __ N.E.3d __, ¶ 12. The question whether the board followed its own
regulations is a legal question. Id. Our review of questions of law is de novo. In
re Application of Duke Energy Ohio, Inc., 166 Ohio St.3d 438, 2021-Ohio-3301,
187 N.E.3d 472, ¶ 11.
{¶ 12} The board and the solar farms maintain that we should defer to the
board’s interpretation of the statutory scheme.2 But we recently rejected the notion
that a court must defer to an agency’s interpretation of a statute that it is tasked with
implementing. TWISM Ents., L.L.C. v. State Bd. of Registration for Professional
Engineers & Surveyors, ___ Ohio St.3d ___, 2022-Ohio-4677, ___ N.E.3d ___,

2. The opinion concurring in part states that “[n]o party in this case has requested that this court
afford deference to the board in its interpretation of any law or regulation.” Concurring opinion,
¶ 75. That is incorrect. See, e.g., Power Siting Board Brief at 7 (case No. 2022-0053), quoting In
re Fuel Adjustment Clauses for Columbus S. Power Co. & Ohio Power Co., 140 Ohio St.3d 352,
2014-Ohio-3764, 18 N.E.3d 1157, ¶ 23, quoting Office of Consumers’ Counsel v. Pub. Util. Comm.,
58 Ohio St.2d 108, 110, 388 N.E.2d 1370 (1979) (“The Court has customarily relied on the expertise
of a state agency in interpreting a law where ‘ “highly specialized issues” ’ are involved and
‘ “where agency expertise would, therefore, be of assistance in discerning the presumed intent of
our General Assembly” ’ ”); id. at 11 (quoting In re Columbus S. Power Co., 134 Ohio St.3d 392,
2012-Ohio-5690, 983 N.E.2d 276, ¶ 36, quoting Office of Consumers’ Counsel at 110, for the
proposition that this court “ ‘will defer to the commission’s interpretation of a statute “where there
exists disparate competence between the respecting tribunals in dealing with highly specialized
issues” ’ ”); Alamo Brief at 12 (case No. 2022-0053) and Angelina Brief at 11 (case No. 2022-
0054), quoting Office of Consumers’ Counsel at 110 (“[T]his Court relies on the expertise of a state
agency in interpreting a law when ‘highly specialized issues’ are involved and ‘where agency
expertise would, therefore, be of assistance in discerning the presumed intent of our General
Assembly’ ”).
Moreover, the citizens repeatedly challenge the board’s determinations about whether
Alamo and Angelina complied with the board’s regulations. These arguments contest both the
board’s interpretation of its regulations and the board’s factual determinations. Thus, it is helpful
to clarify our standard for reviewing the board’s legal and factual determinations at the outset.

5
SUPREME COURT OF OHIO

¶ 3 (“the judicial branch is never required to defer to an agency’s interpretation of
the law” [emphasis in original]).
{¶ 13} This case also presents a related issue: whether a court must give
deference to an agency’s interpretation of its own regulations. The citizens
repeatedly argue that the board incorrectly interpreted its own regulations.3 Under
federal doctrine, a federal court must defer to an agency’s interpretation of an
ambiguous regulation that the agency has promulgated. See Auer v. Robbins, 519
U.S. 452, 461, 137 L.Ed.2d 79, 117 S.Ct. 905 (1997). But the same separation-of-
powers principles that led us to reject Chevron-style deference in TWISM also apply
to deference of the Auer variety. Compare TWISM at ¶ 3, 29 with Chevron, U.S.A.,
Inc. v. Natural Resources Defense Council, Inc., 467 U.S. 837, 865, 81 L.Ed.2d
694, 104 S.Ct. 2778 (1984).
{¶ 14} When a court defers to an agency’s interpretation of its own
regulation, it allows the agency to assume the legislative power (the rule drafter),
the judicial power (the rule interpreter), and the executive power (the rule enforcer).
Doing so violates the fundamental precept that the power of lawmaking and law
exposition should not be concentrated in the same hands. See generally Manning,
Constitutional Structure and Judicial Deference to Agency Interpretations of
Agency Rules, 96 Colum.L.Rev. 612; see also id. at 645, quoting Montesquieu, The
Spirit of the Laws bk. XI, ch. 6, at 157 (Anne Cohler et al. eds. & trans., 1989)
(1768) (“ ‘when legislative power is united with executive power * * * in a single
body * * * there is no liberty’ ”). Thus, we will independently interpret the
regulations at issue in these cases. If the text of a regulation is clear, then we apply
it as written and stop right there. But if we determine that the text is ambiguous,

3. See, e.g., Citizens’ Brief at 22 (case No. 2022-0053) (“The board acted unreasonably and
unlawfully by approving the Project without requiring Alamo to accurately model the noise levels
* * *, in violation of the requirement in Ohio Admin.Code 4906-4-08(A)(3)(b)”); Citizens’ Brief at
27 (case No. 2022-0054) (“The board’s failure to require Angelina to provide [this noise data]
violates Ohio Admin.Code 4906-4-08(D)(4)(e)”).

6
January Term, 2023

we may consider the board’s interpretation only for its persuasive power. See
TWISM at ¶ 44-45.
{¶ 15} The “unreasonable” part of the standard of review comes into play
when we examine the board’s determinations of “[t]he nature of the probable
environmental impact” of each facility and its determinations that each facility
“represents the minimum adverse environmental impact, considering the state of
available technology and the nature and economics of the various alternatives, and
other pertinent considerations,” R.C. 4906.10(A)(2) and (3). The statute dictates
that the board must make these determinations, not this court.
{¶ 16} Here, our review is not of a legal question but of the board’s exercise
of its implementation authority that it was granted by the legislature. We review
the board’s exercise of its implementation authority in making these determinations
for reasonableness. Firelands Wind, __ Ohio St.3d __, 2023-Ohio-2555, __ N.E.3d
__, at ¶ 15. We examine the reasonableness of an agency’s decision about such
things as whether a facility represents the “minimum adverse environmental
impact,” R.C. 4906.10(A)(3), by looking to whether the agency’s decision falls
within a zone of permissible statutory construction. Firelands Wind at ¶ 15. We
also may find an agency’s decision unreasonable when the evidence clearly does
not support it, or when an agency’s decision is internally inconsistent. Id.
{¶ 17} Finally, in adjudicating whether an agency’s determination is
unreasonable, we do “not * * * reweigh the evidence or second-guess [the agency]
on questions of fact.” Lycourt-Donovan v. Columbia Gas of Ohio, Inc., 152 Ohio
St.3d 73, 2017-Ohio-7566, 93 N.E.3d 902, ¶ 35. We will not disturb the board’s
factual determinations “when the record contains sufficient probative evidence to
show that the board’s decision was not manifestly against the weight of the
evidence and was not so clearly unsupported by the record as to show
misapprehension, mistake or willful disregard of duty.” In re Application of

7
SUPREME COURT OF OHIO

Champaign Wind, L.L.C., 146 Ohio St.3d 489, 2016-Ohio-1513, 58 N.E.3d 1142,
¶ 7.
{¶ 18} Applying these standards, we conclude that the citizens’ arguments
lack merit. We find nothing unlawful about the board’s adherence to the
information requirements of its regulations. As we will explain, in some instances,
the board’s rules do not require that Alamo or Angelina provide the information
that the citizens allege. In other instances, Alamo’s and Angelina’s applications
contain the information that the citizens claim is missing. Similarly, we find
nothing unreasonable about the board’s determination of the “nature of the probable
environmental impact” or its determination that each facility “represents the
minimum adverse environmental impact,” R.C. 4906.10(A)(2) and (3).
A. Waiver of Right to Object to Completeness of the Applications
{¶ 19} Before we get to the merits of the citizens’ objections, we need to
deal with a preliminary matter. The solar farms maintain that the citizens waived
their right to challenge the technical completeness of their applications by failing
to object during the proceedings before the board.
{¶ 20} Ohio Adm.Code 4906-3-06(A)(1) and (2) provide that within 60
days of receiving an application, the board chair shall either accept it as complete
or reject it as incomplete with a statement explaining the basis of the rejection.
Alamo and Angelina argue that the citizens waived their argument that the
applications were incomplete by not objecting when the board determined that the
applications were complete.
{¶ 21} In their reply briefs, however, the citizens have clarified that they are
not challenging the technical completeness of the applications. (“Although all
applications must contain the information mandated by rule, the Citizens do not
rely on that position on appeal. * * * [The Citizens] did raise this issue below, but
they are not pursuing it on appeal.”) Instead, they represent that their challenge is
based “on the lack of evidence in the entire record” to support the board’s

8
January Term, 2023

determinations. With that understanding, we proceed to consider the citizens’
propositions of law.
B. Proposition of Law No. 1: Noise
{¶ 22} In their first proposition of law, the citizens assert that the board
erred by issuing certificates without receiving sufficient information about noise
levels of the proposed solar farms and without requiring noise-reduction controls.
{¶ 23} The citizens focus on the anticipated noise from inverters. An
inverter takes the direct-current power generated from solar panels and converts it
to alternating current, which can be transmitted to the grid. Alamo and Angelina
anticipate that the projects will use central inverters, which are typically located in
the center of solar arrays and are able to convert electricity from multiple rows of
solar panels. But they have not ruled out using string inverters instead, which are
smaller and convert power only from a single row (or string) of solar panels.
1. Noise modeling under Ohio Adm.Code 4906-4-08(A)(3)
{¶ 24} As part of their argument, the citizens contend that the board erred
in its determination that the solar farms complied with Ohio Adm.Code 4906-4-
08(A)(3)’s noise-modeling requirements. That provision says:

(3) Noise. The applicant shall provide information on noise
from the construction and operation of the facility.
***
(b) Describe the operational noise levels expected at the
nearest property boundary. The description shall address:
(i) Operational noise from generation equipment. In
addition, for a wind farm, cumulative operational noise levels at the
property boundary for each property adjacent to or within the project
area, under both day and nighttime operations. The applicant shall
use generally accepted computer modeling software (developed for

9
SUPREME COURT OF OHIO

wind turbine noise measurement) or similar wind turbine noise
methodology, including consideration of broadband, tonal, and low-
frequency noise levels.

Ohio Adm.Code 4906-4-08(A).
{¶ 25} Both Alamo and Angelina introduced technical reports on the
background sound and the expected noise impact of the facilities. The reports were
prepared by David Hessler, an engineer with nearly 30 years of acoustic-design
experience. Hessler testified that the noise impact on neighbors would be minimal
or nonexistent. In addition, at their respective supplemental hearings, Alamo and
Angelina submitted noise-modeling data for central inverters. The citizens
contend, however, that the submissions were inadequate because they failed to
include modeling for “the operational noise level at each habitable residence,
school, church, and other noise-sensitive receptors,” Ohio Adm.Code 4906-4-
08(A)(3)(c). They also contend that the board misinterpreted the rule’s
requirements by not mandating that the solar farms submit computer modeling of
the expected sound level if either applicant were to use string inverters rather than
central inverters.
{¶ 26} The flaw in the citizens’ argument is that the administrative-code
provision they cite requires modeling at those locations for wind farms—not solar
farms. See Ohio Adm.Code 4906-4-08(A)(3)(b). Thus, the board did not act
unlawfully by not requiring additional computer modeling.
2. Central-inverter modeling data
{¶ 27} The citizens contend that the modeling data showed that central
inverters will increase background noise at or above 7 dBA4 at some neighboring
property boundaries. They assert that board staff had determined that any increase

4. A-weighted decibel—or dBA—is a scale that measures the loudness of sound as perceived by the
human ear. See Champaign Wind, 146 Ohio St.3d 489, 2016-Ohio-1513, 58 N.E.3d 1142, at ¶ 35.

10
January Term, 2023

in background noise that exceeds 5 dBA threshold “produces noise objectionable
to the community.”
{¶ 28} The citizens claim that the 5 dBA threshold was established in the
board staff’s reports that were filed in each proceeding. The report says: “No non-
participating receptors were modeled to receive noise impacts greater than the
daytime ambient noise level plus 5 dBA. Therefore, the project would be expected
to have minimal adverse noise impacts on the adjacent community.” We do not
read this language as establishing a 5 dBA upper limit. And in any event, a staff
report isn’t an order of the board. It’s just the findings of board staff after their
investigation, and those findings aren’t binding on the board. See R.C. 4906.07(C);
Akron v. Pub. Util. Comm., 55 Ohio St.2d 155, 157, 378 N.E.2d 480 (1978).
{¶ 29} The record contains substantial evidence supporting the board’s
conclusion in each case that sound emissions from the facility “should not have any
negative impact in the surrounding community,” In re Application of Alamo Solar
I, L.L.C., for a Certificate of Environmental Compatibility and Public Need, Power
Siting Board No. 18-1578-EL-BGN, ¶ 237 (June 24, 2021); In re Application of
Angelina Solar I, L.L.C., for a Certificate of Environmental Compatibility and
Public Need, Power Siting Board, No. 18-1579-EL-BGN, ¶ 227 (June 24, 2021).
We reject the citizens’ contention that the central-inverter modeling data
established otherwise.
3. Additional noise-control measures
{¶ 30} The citizens claim that the board erred by failing to require Alamo
and Angelina “to equip the inverters with noise controls, such as cabinet damping
or ventilation silencers, even though these devices are effective and available.”
Based on the evidence submitted, however, the board determined that such noise
controls were unnecessary. Moreover, the record demonstrates that the inverters
can easily be retrofitted with equipment to reduce noise if necessary. Alamo and

11
SUPREME COURT OF OHIO

Angelina both committed in the amended stipulations to promptly make such
retrofits if the need should arise.
{¶ 31} Based on the foregoing, we find nothing unlawful in the board’s
compliance with its own regulations. And we find nothing unreasonable in the
board’s determinations about the solar farms’ expected environmental impact. We
reject the citizens’ first proposition of law.
C. Proposition of Law No. 2: Visual Impact
{¶ 32} Ohio Adm.Code 4906-4-08(D)(4) requires applications to include
information regarding the facility’s expected visual impact. As part of their
applications, Alamo and Angelina submitted visual-resource assessments prepared
by Matthew Robinson, a landscape architect, and his firm. The Alamo assessment
concluded that the project will “not have an undue adverse effect on aesthetic
resources or a significant number of viewers within the study area.” Similarly, the
Angelina assessment concluded that the solar farm “will be screened from view in
approximately 83.2% of the visual study area.” In their second proposition of law,
the citizens make various claims that the visual-impact evidence submitted by the
solar farms was insufficient.
1. Photographic simulations: Ohio Adm.Code 4906-4-08(D)(4)(e)
{¶ 33} To start, the citizens contend that the board failed to ensure
compliance with Ohio Adm.Code 4906-4-08(D)(4)(e), which requires that an
applicant:

[p]rovide photographic simulations or an artist’s pictorial sketches
of the proposed facility from public vantage points that cover the
range of landscapes, viewer groups, and types of scenic resources
found within the study area.

12
January Term, 2023

Robinson’s reports included photographic simulations of the proposed facilities
from public vantage points. The citizens raise two objections to these simulations.
{¶ 34} First, the citizens complain that only eight-foot solar panels were
depicted even though the solar farms could install panels up to 14 feet high. But
Robinson testified that the simulations depicted eight-foot solar panels rather than
14-foot panels because eight feet was the most likely height of the panels. Further,
Robinson testified that if he were to conduct the visual simulations with a panel
height of 14 feet, it would not change his conclusions.
{¶ 35} Second, the citizens claim that because the board allowed
simulations that did not convey how the projects will appear to the closest, most
impacted neighbors, it misread the mandate in Ohio Adm.Code 4906-4-
08(D)(4)(e), which requires such simulations to “cover the range of landscapes
[and] viewer groups.” The third condition in the amended stipulations filed in each
case requires that perimeter fences be set back at least 25 feet from neighbors’
property lines and 150 feet from houses. The citizens complain that the simulations
filed with the applications did not depict views from these distances but instead
depicted views from 300 to 900 feet away. But the setbacks in the amended
stipulations were not agreed to until July 2020, more than 18 months after Alamo
and Angelina filed their applications. Thus, the solar farms could not have
accounted for the revised setback distances in their applications. Moreover, Ohio
Adm.Code 4906-4-08(D)(4)(e) requires only photographic simulations from
“public vantage points.” The regulation does not require Alamo and Angelina to
provide photographic simulations from the vantage point of private property.
2. Mitigation of adverse visual impacts
{¶ 36} The citizens also argue that Alamo and Angelina failed to comply
with Ohio Adm.Code 4906-4-08(D)(4)(f). That provision requires the applicant to
“[d]escribe measures that will be taken to minimize any adverse visual impacts
created by the facility, including, but not limited to, project area location, lighting,

13
SUPREME COURT OF OHIO

* * *, visual screening, and facility coloration.” Id. The citizens claim that the
solar farms violated this provision because their applications contained only
references to certain mitigating measures they were “considering,” rather than firm
commitments to implement any mitigating measures.
{¶ 37} Contrary to the citizens’ assertion, Alamo’s and Angelina’s
applications described specific mitigation measures that will be incorporated into
their project designs, as well as other measures that are being considered for the
projects. Definite measures include installing electricity-collection lines
underground, constructing solar arrays on existing grades that follow the existing
topography of the project area, and planting native grasses in the solar field and
under arrays. Alamo and Angelina are also considering planting native shrubs and
trees along fence lines adjacent to residences to soften the overall visual effect of
the projects and integrate the projects into the surrounding landscape.
{¶ 38} Notwithstanding these measures, the citizens fault the solar farms
for failing to include a binding landscape plan in their applications so that neighbors
could adjudicate the details and adequacy of the vegetative screening chosen for
the project. But the administrative-code provision at issue doesn’t require that the
applicant commit to any specific type of visual screening; nor does it require the
applicant to include a landscape plan with the application, let alone a binding one.
{¶ 39} The citizens also argue that the board misinterpreted the rule
requiring a description of steps to mitigate visual impacts, Ohio Admin.Code 4906-
4-08(D)(4)(f), by permitting Alamo and Angelina to file a post certification
landscape plan. The stipulations require the plans to be developed in consultation
with a licensed landscape architect and include mitigation measures such as
fencing, vegetative screening, and good-neighbor agreements. The citizens
contend that by granting certification before binding landscape plans are filed, the
board improperly delegated authority to board staff and deprived the public of a fair
opportunity to have the adequacy of the screening plans adjudicated. They further

14
January Term, 2023

maintain that these conditions provide ambiguous parameters and lack enforceable
standards.
{¶ 40} Contrary to the citizens’ assertion, they were not deprived of an
opportunity to be heard on the mitigation measures required by the stipulations.
During the hearings on the amended stipulations, Alamo and Angelina introduced
a preliminary visual-impact mitigation plan that showed how setbacks and
vegetative screening will be incorporated into the projects. The citizens were able
to cross-examine Alamo’s and Angelina’s witnesses on the preliminary plan.
Moreover, the stipulated conditions expressly require that if the solar companies
and neighboring property owners are unable to agree to alternative screening
measures, the landscape plans must provide vegetative screening that will “enhance
the view from the residence and be in harmony with the existing vegetation and
viewshed.” In addition, the conditions require that the vegetative screenings be
maintained for the life of the solar farms and that failed plantings be replaced.
{¶ 41} We find nothing unlawful in the board’s actions. R.C. 4906.10(A)
empowers the board to grant a siting certificate “upon such terms, condition, or
modifications of the construction, operation, or maintenance” of the facility as the
board deems appropriate. Thus, we have upheld the board’s authority to impose
conditions that are subject to monitoring for compliance by board staff. See In re
Application of Buckeye Wind, L.L.C., 131 Ohio St.3d 449, 2012-Ohio-878, 966
N.E.2d 869, ¶ 13-18 (plurality opinion); In re Application of Icebreaker
Windpower, Inc., 169 Ohio St.3d 617, 2022-Ohio-2742, 207 N.E.3d 651, ¶ 39-40.
Alamo and Angelina must construct their solar facilities in accordance with the
conditions established by the board. So even though the board’s orders allow
Alamo and Angelina to flesh out the details in the final versions of their landscape
plans as the construction process evolves, the board did not act unlawfully in
approving the facilities subject to these conditions. See Buckeye Wind at ¶ 18
(plurality opinion).

SUPREME COURT OF OHIO

3. Setbacks
{¶ 42} The citizens claim that the stipulated 25-foot setback between the
facilities’ fences and neighboring property lines is insufficient for vegetative
screening. The solar farms presented evidence that a 25-foot setback is sufficient
to effectively screen and mitigate each project’s visual impact by (1) reducing the
perceived scale of the project and (2) providing increased space to allow for more
vegetative screening. The citizens, in contrast, failed to cite any evidence that the
25-foot setback is insufficient to mitigate adverse visual impacts. This failure to
support a factual argument with record evidence is grounds for rejection. See In re
Application of Columbus S. Power Co., 147 Ohio St.3d 439, 2016-Ohio-1608, 67
N.E.3d 734, ¶ 51 (lead opinion); see also Champaign Wind, 146 Ohio St.3d 489,
2016-Ohio-1513, 58 N.E.3d 1142, at ¶ 30 (whether setbacks are sufficient to protect
the public is an evidentiary issue, and we will not substitute our judgment for the
board on evidentiary matters).
{¶ 43} The citizens also contend that the board should have required Alamo
and Angelina to completely screen the neighbors’ homes from intrusive views of
solar panels and fences. But they do not point to any legal authority that requires
solar farms to be completely screened off from neighboring properties. R.C.
4906.10(A)(3) requires the board to certify “[t]hat the facility represents the
minimum adverse environmental impact, considering the state of available
technology and the nature and economics of the various alternatives, and other
pertinent considerations.” It does not require the elimination of all adverse impacts.
{¶ 44} Based on the foregoing, we reject the citizens’ second proposition of
law.
D. Proposition of Law No. 3: Wildlife and Plants
{¶ 45} In their third proposition of law, the citizens assert that the board
acted unlawfully and unreasonably by approving the facilities without receiving
sufficient information about the projects’ probable impact on animals and plants.

16
January Term, 2023

{¶ 46} The citizens’ arguments center on Ohio Adm.Code 4906-4-08(B)(1),
which requires an applicant to “provide information regarding ecological resources
in the project area.” Under that regulation, the applicant must

[p]rovide the results of a literature survey of the plant and
animal life within at least one-fourth mile of the project area
boundary. The literature survey shall include aquatic and terrestrial
plant and animal species that are of commercial or recreational
value, or species designated as endangered or threatened.

Ohio Adm.Code 4906-4-08(B)(1)(c).
{¶ 47} And the applicant must “[c]onduct and provide the results of field
surveys of the plant and animal species identified in the literature survey.” Ohio
Adm.Code 4906-4-08(B)(1)(d). The citizens contend that the board misinterpreted
this regulation when it required that Alamo and Angelina conduct a literature search
only for species of commercial and recreational value. We disagree.
{¶ 48} Alamo and Angelina retained the same environmental consulting
firm, Cardno, to conduct literature and field surveys of plant and animal life within
one-quarter mile of the project areas. The Cardno team reviewed literature
compiled by several state and federal agencies, including the Ohio Department of
Natural Resources and the United States Fish and Wildlife Service. Contrary to the
citizens’ claim, Cardno’s literature surveys include specific discussions of all sorts
of birds (including raptors such as bald eagles), bats, and aquatic life in and near
the project areas. Likewise, the literature surveys extensively discuss the various
plant species in and near the project areas. In short, Alamo’s and Angelina’s
literature surveys satisfy Ohio Adm.Code 4906-4-08(B)(1)(c).
{¶ 49} The Cardno team also conducted three separate field surveys for
each of the project sites and the areas within one-quarter mile of the project area

17
SUPREME COURT OF OHIO

boundaries. Cardno’s field surveys were focused on observing habitats for
evidence of nesting, roosting, and foraging to determine whether the project sites
and surrounding areas were conducive to wildlife before and after construction. In
conducting habitat assessments of the project sites and surrounding areas, the
Cardno team searched for activity of certain species of bats and birds (including
bald eagles and other raptors), as well as endangered and threatened species. The
Cardno team also surveyed wetlands to observe wildlife and to determine their
ecological viability for animal and aquatic life.
{¶ 50} The citizens claim that Cardno’s field surveys were inadequate
because all the Cardno team did was “casually note” the rare, threatened, and
endangered species that it observed during its surveys of wetlands and streams in
the project areas. They maintain that even if the Cardno team happened to observe
wildlife during these visits, the team was not searching for wildlife when it
surveyed the wetlands and streams.
{¶ 51} We are not persuaded. As an initial matter, the citizens’ challenge
is to the methodology employed by the Cardno team in conducting field surveys of
the animals found in and around the project areas. But nothing in Ohio Adm.Code
4906-4-08(B)(1)(d) prescribes a specific methodology for how field surveys are to
be conducted.
{¶ 52} Further, the record does not establish that the Cardno team’s
methods were unreasonable or its work inadequate. The Cardno team reported that
few wildlife species use the areas that were surveyed because each project is to be
built mostly on land that has already been cleared and is disturbed annually by
agricultural activity. The Cardno team recorded the results of its wildlife field
surveys of the project areas, and the results were generally consistent with its
conclusion that the project areas provide suitable habitats for only a limited number
of wildlife species.

18
January Term, 2023

{¶ 53} In the end, the citizens have not shown that Alamo or Angelina failed
to comply with Ohio Adm.Code 4906-4-08(B)(1)(c) or (d). As a result, they have
failed to demonstrate that the record lacks sufficient evidence to support the board’s
determinations pertaining to the probable impact of the solar farms on plant and
animal life in the project areas. Therefore, we reject their third proposition of law.
E. Proposition of Law No. 4: Flooding and Stormwater Runoff
{¶ 54} In their fourth proposition of law, the citizens contend that the board
misinterpreted the rule governing water quality information, Ohio Admin.Code
4906-4-07(C), to allow it to approve the facilities without obtaining sufficient
information about the potential for flooding as a result of stormwater runoff from
the facilities.
{¶ 55} Alamo and Angelina presented testimony from Noah Waterhouse, a
licensed professional engineer with extensive experience evaluating water issues at
solar projects. He testified that the project “should not have an impact on drainage,
nor should it result in an increase in runoff.” He further opined that the drainage
and runoff conditions “should not be dissimilar from a farmed field” containing
crops and should be superior to a fallow field.
{¶ 56} The board approved conditions that require the solar farms to follow
Ohio EPA programs for the management of stormwater, to implement a
stormwater-pollution-prevention plan, and to incorporate the Ohio EPA’s
“Guidance on Post-Construction Storm Water Controls for Solar Panel Arrays.”
Matt Marquis, a civil engineer with expertise in stormwater management,
confirmed that the conditions “adequately provide for management of any post-
construction stormwater flows.”
{¶ 57} The citizens contend that the board erred by approving the projects
without obtaining information about stormwater runoff and potential flooding,
which they assert the board is required to obtain under Ohio Adm.Code 4906-4-
07(C). That provision, however, is not directed at flooding and stormwater issues

19
SUPREME COURT OF OHIO

but at ensuring that projects will comply with federal, state, and local regulations
for water pollution. See Ohio Adm.Code 4906-4-07(A) (“[t]he information
requested in this rule shall be used to determine whether the facility will comply
with regulations for air and water pollution, solid and hazardous wastes, and
aviation”). Even subsection (C) of the rule, which the citizens cite, calls for the
applicant to “provide information on compliance with water quality regulations.”
(Emphasis added.) Ohio Adm.Code 4906-4-07(C).
{¶ 58} Flooding is addressed by a different rule, namely Ohio Adm.Code
4906-4-08(A)(4)(e). Under this rule, the applicant is required to “[p]rovide an
analysis of the prospects of floods for the area, including the probability of
occurrences and likely consequences of various flood stages, and describe plans to
mitigate any likely adverse consequences.” Id. The citizens do not argue that
Alamo and Angelina failed to address flooding impacts under this rule.
{¶ 59} Based on the foregoing, we reject the citizens’ fourth proposition of
law.
F. Proposition of Law No. 5: Pollution Impacts and Mitigation Measures
{¶ 60} In their fifth proposition of law, the citizens contend that the solar
farms’ applications failed to provide adequate information about the quality of
surface water flowing from the project areas and failed to provide measures to
mitigate potential contaminants discharged into surface waters from the
construction of the solar farms.
1. Pollution impacts
{¶ 61} There are two rules at issue that deal with water quality—one relates
to water quality before construction and the other to water quality during
construction. Ohio Adm.Code 4906-4-07(C)(1) requires the applicant to “provide
information regarding preconstruction water quality and permits.” Under
subsection (C)(1)(d), the applicant must “[d]escribe the existing water quality of
the receiving stream based on at least one-year of monitoring data, using

20
January Term, 2023

appropriate Ohio environmental protection agency reporting requirements.” Ohio
Adm.Code 4906-4-07(C)(1)(d). And Ohio Adm.Code 4906-4-07(C)(2) requires
the applicant to “provide information regarding water quality during construction.”
Under subsection (C)(2)(b), the applicant must provide an “estimate of the quality
and quantity of aquatic discharges from the site clearing and construction
operations.” Ohio Adm.Code 4906-4-07(C)(2)(b).
{¶ 62} Regarding the preconstruction rule, the citizens argue that Alamo
and Angelina failed to sample and analyze the water quality in streams receiving
runoff from the project areas. As for the during-construction rule, the citizens
contend that the solar farms failed to provide “data” estimating the quality of
aquatic discharges from construction.
{¶ 63} But the preconstruction rule requires water samples to be collected
“only in bodies of water likely to be affected by the proposed facility.” Ohio
Adm.Code 4906-4-07(C)(1)(b). Alamo and Angelina averred that water-quality
monitoring for preconstruction surveys was not necessary, because the projects will
not create any water-related discharges or wastewater and there will be no streams
receiving runoff.
{¶ 64} Similarly, the rule dealing with water quality during construction
requires only an “estimate” of the “quality * * * of aquatic discharges from the site
clearing and construction operations.” Ohio Adm.Code 4906-4-07(C)(2)(b).
Alamo and Angelina have provided such an estimate. They averred that
construction “will not cause any aquatic discharges” and “will involve only limited
activities requiring the management of storm-water related pollutants” and that no
effluents are expected to be discharged into bodies of water or receiving streams
during site clearing and construction.
2. Mitigation measures
{¶ 65} The citizens maintain that Alamo and Angelina failed to comply
with Ohio Adm.Code 4906-4-07(C)(2)(c), which requires an applicant to

21
SUPREME COURT OF OHIO

“[d]escribe any plans to mitigate the above effects”—referring to the estimated
aquatic discharges from site clearing and construction under subsection (C)(2)(d)—
“in accordance with current federal and Ohio regulations.” The citizens also assert
a violation of Ohio Adm.Code 4906-4-07(C)(2)(e), which requires an applicant to
“[d]escribe the equipment proposed for control of effluents discharged into bodies
of water and receiving streams.”
{¶ 66} The citizens concede that the solar farms’ applications generally
describe equipment and measures that would be employed to protect surface waters
from soil erosion and sedimentation. The citizens also acknowledge that both
applicants further agreed to mitigate any contamination of surface waters caused
by the projects through specific conditions in their amended stipulations. The
citizens accuse the board of having “overlooked” data requirements in its own rules,
and they fault it for simply accepting that these mitigation measures will be
implemented when Alamo and Angelina apply for stormwater permits under the
conditions set forth in the amended stipulations.
{¶ 67} But again, R.C. 4906.10(A) empowers the board to grant a siting
certificate “upon such terms, conditions, or modifications of the construction,
operation, or maintenance” of the facility as the board deems appropriate. The
conditions are binding on Alamo and Angelina and are subject to monitoring for
compliance by board staff. See Buckeye Wind, 131 Ohio St.3d 449, 2012-Ohio-
878, 966 N.E.2d 869, at ¶ 17 and ¶ 32 (plurality opinion).
{¶ 68} Accordingly, we reject the citizens’ fifth proposition of law.
G. Proposition of Law No. 6: Setbacks
{¶ 69} In their final proposition of law, the citizens argue that the board
violated the requirement that it determine that the facilities represent the minimum
adverse environmental impact by accepting unreasonably narrow setbacks between
the solar farms and neighboring land and homes.

22
January Term, 2023

{¶ 70} We have already rejected the citizens’ argument that the setbacks
were insufficient for visual screening as part of our discussion addressing the
second proposition of law. The citizens also argue that the setbacks approved by
the board fall short of protecting neighbors from inverter noise. But whether
setbacks are sufficient to protect the public from adverse environmental impacts is
an evidentiary issue. Champaign Wind, 146 Ohio St.3d 489, 2016-Ohio-1513, 58
N.E.3d 1142, at ¶ 30. The citizens failed to present any evidence that the setbacks
approved in these cases are insufficient to mitigate noise impacts. Therefore, they
have not met their burden to demonstrate that the board acted unreasonably in its
determination under R.C. 4906.10(A)(3) that the proposed facilities represent the
minimum adverse environmental impact. We reject the citizens’ sixth proposition
of law.
III. CONCLUSION
{¶ 71} The citizens have failed to establish that the board acted unlawfully
by not complying with its own regulations. And they have failed to establish that
the board acted unreasonably in making the determinations required by R.C.
4906.10(A). Therefore, we affirm the board’s orders granting the certificates.
Orders affirmed.
FISCHER, DONNELLY, and DETERS, JJ., concur.
KENNEDY, C.J., concurs in judgment only.
BRUNNER, J., concurs in part and concurs in the judgment, with an opinion
joined by STEWART, J.
_________________
BRUNNER, J., concurring in part and concurring in judgment.
{¶ 72} I concur in the judgment of the court, and I concur in the analysis set
forth in part II, sections A through G of the majority opinion. I write separately
because the majority opinion improperly and unnecessarily discusses our holding
in TWISM Ents., L.L.C. v. State Bd. of Registration for Professional Engineers &

23
SUPREME COURT OF OHIO

Surveyors, ___ Ohio St.3d ___, 2022-Ohio-4677, ___ N.E.3d ___, regarding the
activities of appellee, the Ohio Power Siting Board, when that case is not relevant
or applicable to reviewing the issues raised by the parties. Appellants, Concerned
Citizens of Preble County, L.L.C., and certain individual members of that group
(collectively, “the citizens”), challenge whether appellee, the board, had before it
the right kind or amount of evidence necessary to make the required determinations
before granting the applications of intervening appellees, Alamo Solar I and
Angelina Solar I (collectively, “the solar-energy companies”). These are issues of
fact.5
{¶ 73} Therefore, our task is straightforward: we must determine whether
the board’s decisions were manifestly against the weight of the evidence and were
so clearly unsupported by the record as to show misapprehension, mistake, or
willful disregard of duty, Monongahela Power Co. v. Pub. Util. Comm., 104 Ohio
St.3d 571, 2004-Ohio-6896, 820 N.E.2d 921, ¶ 29. The majority performs this task
and affirms the orders of the board.
{¶ 74} This is quite different from what we were tasked with in TWISM,
which was to determine what the terms in a statute mean. TWISM at ¶ 1-2. In
TWISM, a majority of this court decided to revisit our approach to agency
deference. Id. at ¶ 20. The majority opinion in that case concluded that when the
meaning of a law is in dispute, it is the task of the judiciary, not an administrative
agency, to ultimately determine what the law means. Id. at ¶ 3. Therefore, a court
may consider but need not defer to an agency’s interpretation of a statute that the
agency is charged by law with administering. Id. First, I do not argue with the
principle of law announced in TWISM. But the danger of mentioning it in this

5. The majority attempts to reframe the citizens’ arguments as asserting that the board
“misinterpreted” its regulations. Majority opinion, ¶ 9, 25, 39, 47, 54. However, the terms
“misinterpret,” “misinterpreted,” or “misinterpretation” do not appear anywhere in the citizens’
merit or reply briefs.

24
January Term, 2023

context is that the next step will be that it has application in this context when, here,
it simply does not apply. Nor do the facts or assertions of the parties support its
use.
{¶ 75} The majority opinion hypothesizes the existence of claims by the
board and the solar-energy companies that this court “should defer to the board’s
interpretation of the statutory scheme.” Majority opinion at ¶ 12. But this
“statutory scheme” deference is not argued by the parties in their briefs. And no
party in this case has requested that this court afford deference to the board in its
interpretation of any law or regulation.6
{¶ 76} The board did ask this court for deference in its determination of the
facts. And the solar-energy companies argued that the board’s decisions, which
involved assessing the weight and credibility of the evidence, “should be afforded
deference.” Giving deference to the board in its factual determination of the
evidence is consistent with established caselaw. In re Application of Duke Energy
Ohio, Inc., 166 Ohio St.3d 438, 2021-Ohio-3301, 187 N.E.3d 472, ¶ 39 (“[The Ohio
Power Siting B]oard’s evaluation of the evidence merits deference, and we will not
disturb it”), citing Cleveland Elec. Illum. Co. v. Pub. Util. Comm., 76 Ohio St.3d
163, 165, 666 N.E.2d 1372 (1996).
{¶ 77} Moreover, the majority opinion does not actually interpret any
statute or regulation as part of its review. Thus, there is no need to explain, let alone
extend, the holding in TWISM, ___ Ohio St.3d ___, 2022-Ohio-4677, ___ N.E.3d
___, when there is no call for its application. In fact, in applying R.C.
4906.10(A)(2) and (3)7 in this case, the majority explicitly finds that we must defer

6. The parties did reference cases in their briefs that support the idea that courts should give
deference to an agency’s interpretation of a statute, but we have since clarified our position on that
issue through our decision in TWISM, ___ Ohio St.3d ___, 2022-Ohio-4677, ___ N.E.3d ___.
Furthermore, referencing those cases does not bring the issue of agency deference involving
regulations or administrative rules squarely before us.
7. R.C. 4906.10(A) provides:

25
SUPREME COURT OF OHIO

to the board’s determinations of the probable environmental impacts. Majority
opinion at ¶ 15 (“The statute dictates that the board must make these
determinations, not this court”). Thus, the majority’s discussion of TWISM here is
inapposite. No party asks us to employ or denounce agency-interpretation
deference regarding a statute or regulation. Because the discussion related to
TWISM in the majority opinion does not apply to the facts and legal arguments
made here, it does not create legal precedent.
{¶ 78} Further, to the extent that the majority opinion insinuates that the
holding in TWISM—that a court may consider but need not defer to an agency’s
interpretation of a statute—applies equally to an agency’s interpretation of its own
regulations, see majority opinion at ¶ 13, it is wrong. State agencies promulgate
administrative rules when they are empowered by statute to do so. Here, the board
is empowered by R.C. 4906.03(C) to promulgate “rules establishing criteria for
evaluating the effects on environmental values of proposed and alternative sites.”
It is the board that would know what it intended to say in its own regulations, and
it is the board that would know how it intended the regulations to be applied. See
R.C. 119.01(A)(1) (“ ‘Agency’ means, except as limited by this division, any
official, board, or commission having authority to promulgate rules”); R.C.
119.01(C) (“ ‘Rule’ means any rule, regulation, or standard, having a general and
uniform operation, adopted, promulgated, and enforced by any agency under the
authority of the laws governing such agency”); R.C. 119.02 (“Every agency
authorized by law to adopt, amend, or rescind rules shall comply with the procedure

The board shall not grant a certificate for the construction, operation, and
maintenance of a major utility facility, either as proposed or as modified by the
board, unless it finds and determines all of the following:
***
(2) The nature of the probable environmental impact;
(3) That the facility represents the minimum adverse environmental
impact, considering the state of available technology and the nature and
economics of the various alternatives, and other pertinent considerations.

26
January Term, 2023

prescribed in sections 119.01 to 119.13, inclusive, of the Revised Code”); R.C.
119.03(G)(3) (“The general assembly, by adopting a concurrent resolution, and in
accordance with section 107.43 of the Revised Code, may do either of the
following: (a) Invalidate, in whole or in part, an emergency rule adopted or
amended by an agency in response to a state of emergency, as defined under section
107.42 of the Revised Code, under division (G)(1) of [R.C. 119.03]; (b) Authorize
an agency to readopt, in whole or in part, a rule that was rescinded in response to a
state of emergency under division (G)(1) of [R.C. 119.03]” [emphasis added]).
{¶ 79} Importantly, the parties here did not present the agency-deference
issue addressed in TWISM to this court. Nor has that issue been briefed or argued;
it plays no part in our resolution of this case, and the majority’s discussion of
TWISM is a distraction that is beyond the scope of what we were tasked with
deciding.
{¶ 80} For these reasons, I respectfully concur in part and concur in the
judgment.
STEWART, J., concurs in the foregoing opinion.
