ZINTER, Justice

[¶1.]         The Board of Minerals and Environment (Board) authorized the

Department of Environment and Natural Resources (DENR) to issue an air quality

permit to Hyperion Refining, LLC (Hyperion). The permit was necessary for

Hyperion to begin construction of a proposed petroleum refinery and power plant.

Three citizens groups appealed to circuit court. Hyperion also appealed a permit

condition limiting the amount of carbon monoxide that could be emitted from the

proposed facility. The circuit court affirmed the Board’s decision in all respects.

The citizens groups now appeal the issuance of the permit, and Hyperion appeals

the permit’s carbon monoxide limit. We affirm.

                            Facts and Procedural History

[¶2.]         This case involves the issuance of a “Prevention of Significant

Deterioration Air Quality” permit (PSD permit) to Hyperion. Hyperion proposed to

construct a large petroleum refinery and power plant in Union County. 1 Federal

and state regulations required Hyperion to obtain a PSD permit before constructing

the facility. Among other things, a PSD permit regulates air quality by limiting the

pollutants a facility may emit into the ambient air.

[¶3.]         In December 2007, Hyperion submitted a PSD permit application

containing 613 pages of materials to DENR. Three citizens groups—Save Union




1.      Hyperion’s proposed facility includes a refinery and a power plant. Hyperion
        proposed to refine Canadian crude from oil sands into ultralow sulfur
        gasoline, heating oil, diesel fuel, and low sulfur jet fuel. The power plant
        would provide most of the electricity needed by the refinery. Additional
        electricity would be purchased commercially.

                                          -1-
#26290, #26293

County, Citizens Opposed to Oil Pollution, and the Sierra Club (collectively,

“Citizens”)—intervened and contested issuance of the permit.

[¶4.]         Citizens also requested that a state environmental impact statement

(EIS) be prepared before the permit was issued. DENR, the state agency in charge

of preparing EISs and considering PSD permits, denied Citizens’ request. On

December 15, 2008, after extensive study and responses to public comments, DENR

recommended approval of a PSD permit with ninety-six pages of conditions.

[¶5.]         DENR’s recommendation was challenged, and in the summer of 2009,

the proposed permit was litigated in ten days of contested case hearings before the

Board. Twice during the hearings, Citizens renewed their request for an EIS. The

requests were denied. 2 On August 20, 2009, the Board authorized DENR to issue

the permit.

[¶6.]         One permit condition imposed a “commence construction” deadline of

eighteen months, which was February 20, 2011. The permit provided that, if

construction of the facility was not commenced by that date, the permit “[became]

invalid.” The permit, however, allowed DENR’s Secretary to grant an extension of

time to commence construction if Hyperion applied for the extension within the

eighteen-month time period and demonstrated that the extension was justified.



2.      Citizens requested the Board to review DENR’s decision to not order an EIS.
        Citizens also requested the Board to order an EIS. In its findings of fact and
        conclusions of law, the Board ruled that “an EIS is not necessary for
        consideration in this matter, and the DENR properly exercised its authority
        and discretion [in] choosing not to perform an EIS.” DENR contends that the
        Board had no authority to review DENR’s decision. We do not address that
        contention because we conclude that neither the Board nor DENR abused its
        discretion in declining to order an EIS.

                                          -2-
#26290, #26293

[¶7.]          Another permit condition required that carbon monoxide emissions

from the proposed facility’s twenty large “process heaters” could not exceed certain

“Best Available Control Technology” (BACT) limits. BACT limits are designed to

require the maximum degree of reduction of pollutant emissions that is achievable.

The permit imposed a carbon monoxide BACT limit of 0.007 lb/mmBtu (pounds per

million British thermal units) for the process heaters.

[¶8.]          Citizens appealed the issuance of the permit to circuit court. Hyperion

filed a separate appeal challenging the carbon monoxide BACT limit. Hyperion

argued that 0.010 lb/mmBtu was the achievable limit.

[¶9.]          On June 23, 2010, while the appeals were pending, the circuit court

granted a Hyperion motion to remand the matter to allow the Board to consider

additional evidence on several issues, including a request to extend the commence

construction deadline. On the same date, Hyperion filed an application with DENR

to extend the commence construction deadline to August 20, 2012.

[¶10.]         DENR then began the process of investigating, soliciting public

comments, and considering new evidence on the new issues and the request to

extend the commence construction deadline. Over the next eight months, DENR

made numerous requests of Hyperion for additional information to address the new

issues and the request for an extension. 3 DENR ultimately proposed a draft

amended permit, which included an extension of the commence construction

deadline. The draft amended permit was made available for public comment on



3.       All requested information was submitted by February 14, 2011.


                                          -3-
#26290, #26293

February 14, 2011, six days before the original commence construction deadline was

to expire. The public comment period ran from February 14, 2011, to April 1, 2011.

[¶11.]         On March 21, 2011, the Board entered a scheduling order. The order

set a July 2011 contested case hearing to consider the proposed amended permit.

On March 31, 2011, Hyperion filed its comments on the draft amended permit. In

its comments, Hyperion requested that the commence construction deadline be

extended to eighteen months after the Board approved the amended permit. 4

[¶12.]         After public comments and DENR’s response to public comments, a

four-day contested case hearing on the amended permit was held in July 2011.

Extensive expert testimony and nearly 4,000 pages of exhibits were presented to the

Board. Hyperion indicated that it had not commenced construction because of the

national economic downturn; the need to address new federal regulations regarding

sulfur dioxide and nitrogen dioxide emissions; the identification of a new emission

source that required correction of the initial permit; and the uncertainty of the

permit’s status as a result of the ongoing litigation.

[¶13.]         On September 16, 2011, the Board entered findings and conclusions

approving DENR’s issuance of the amended permit. The amended permit

incorporated Hyperion’s request to extend the commence construction deadline to

eighteen months after the effective date of the amended permit. The amended

permit retained the carbon monoxide 0.007 lb/mmBtu BACT limit.




4.       Neither DENR nor the Board formally and finally acted on this request for an
         amended commenced construction deadline until the conclusion of the
         contested case proceedings.

                                           -4-
#26290, #26293

[¶14.]       Citizens then appealed the Board’s September 2011 decision. The

circuit court consolidated the 2011 appeal with Hyperion’s and Citizens’ 2009

appeals. In a detailed memorandum decision, the court ultimately affirmed the

decisions not to order an EIS, affirmed the determination that Hyperion presented

satisfactory justification for the extension of the commence construction deadline,

affirmed the issuance of the amended permit, and affirmed the carbon monoxide

0.007 lb/mmBtu BACT limit.

[¶15.]       We consider the following issues raised by Citizens:

             1. Whether an EIS should have been ordered before the issuance of
                the PSD permit.

             2. Whether the initial permit “became invalid” when the Board
                neither ruled on Hyperion’s request to extend the commence
                construction deadline within the original eighteen-month period nor
                adopted the ultimate deadline that was requested within that
                period.

             3. Whether Hyperion presented satisfactory justification for its
                request to extend the commence construction deadline.

We consider the following issue raised by Hyperion:

             4. Whether the Board clearly erred in determining the carbon
                monoxide BACT limit.

                                       Decision

[¶16.]       “We review agency decisions the same as the circuit court . . . .” St.

Pierre v. State ex rel. S.D. Real Estate Comm’n, 2012 S.D. 25, ¶ 14, 813 N.W.2d 151,

156. We “give great weight to the findings made and inferences drawn by an agency

on questions of fact.” SDCL 1-26-36. “[Q]uestions of law are reviewed de novo.”

Brown v. Douglas Sch. Dist., 2002 S.D. 92, ¶ 9, 650 N.W.2d 264, 267. We may

reverse agency decisions when “substantial rights of the appellant have been

                                          -5-
#26290, #26293

prejudiced because the administrative findings, inferences, conclusions, or

decisions” are, among other things, in violation of statutes, affected by an error of

law, are clearly erroneous, or constitute an abuse of discretion. SDCL 1-26-36.

     1. Environmental Impact Statement

[¶17.]         SDCL chapter 34A-9 is South Dakota’s Environmental Policy Act.

SDCL 34A-9-4 provides in relevant part: “All agencies may prepare, or have

prepared by contract, an environmental impact statement on any major action they

propose or approve which may have a significant effect on the environment.” 5

However, the Act is separate from, and involves environmental concerns in addition


5.       The Board and DENR are “agencies.” See SDCL 34A-9-1 (defining an
         “[a]gency” as “the executive and administrative departments, offices, boards,
         commissions, and other units of the state government”). The parties,
         however, disagree whether issuing a PSD permit is an “action” that allows
         both agencies to order an EIS under SDCL chapter 34A-9. Citizens argue
         that SDCL 34A-9-2(3) specifically defines the issuance of a PSD permit as an
         agency “action.” That statute provides: “As used in [chapter 34A-9], the term,
         actions, includes . . . [t]he issuance by one or more public agencies of a lease,
         permit, license, certificate, or other public entitlement to an applicant.”
         SDCL 34A-9-2. The Board and Hyperion argue that issuing a PSD permit is
         not an agency “action.” They rely on SDCL 34A-9-3(5), which provides: “As
         used in [chapter 34A-9], the term, actions, does not include . . . [a]ctions of an
         environmentally protective regulatory nature.” The Board and Hyperion
         contend that PSD permits are environmentally protective regulations.

         Environmentally protective regulations are substantially different than PSD
         permits. A permit (like the PSD permit) is issued to an individual party (like
         Hyperion), authorizing that party to engage in a particular activity. In
         contrast, environmentally protective regulations have broad non-
         individualized application. Regulations apply to the citizenry as a whole.
         Because a PSD permit only authorizes an identified permit holder to engage
         in identified activities, it is not an environmentally protective regulation
         within the meaning of SDCL 34A-9-3(5). We also note that SDCL 34A-9-2(3)
         is the more specific statute. We conclude that PSD permitting is governed by
         SDCL 34A-9-2(3), which specifically makes permitting an agency “action.”
         The Board and DENR were authorized to order an EIS before issuing
         Hyperion’s PSD permit.

                                             -6-
#26290, #26293

to those that are relevant in PSD air quality permitting. Compare South Dakota

Environmental Policy Act’s broad application to any action that may have a

significant impact on the environment with ARSD 74:36:09:02’s provisions only

involving air quality.

[¶18.]       Citizens first argue that the Board erroneously determined it had no

jurisdiction to order an EIS under SDCL chapter 34A-9. Citizens misconstrue the

Board’s determination. The Board did not determine that it had no jurisdiction to

order an EIS. The Board determined that “an EIS is much broader and

encompasses many subject matters over which the Board has no jurisdiction.” We

agree with the Board’s determination.

[¶19.]       Citizens acknowledge that, in addition to an assessment of air quality,

an EIS would assess the proposed project’s other environmental effects, such as

effects on roads, soils, water resources, noise, waste disposal, etc. But the only

“action” proposed to be approved was the issuance of a PSD permit. See SDCL 34A-

9-2, -4. Therefore, the Board’s jurisdiction in this proceeding did not include

regulatory authority over “all the [other environmental] factors which the [Citizens]

deem relevant to the [permit] consideration.” See In re Solid Waste Disposal Permit

Application, 268 N.W.2d 599, 601 (S.D. 1978). The Board’s jurisdiction was limited

to the specific requirements established in the statutes and regulations for issuance

of the air quality permit. See id. at 600-01. Thus, the Board correctly recognized

that its jurisdiction was limited to the PSD permit issues, and the Board had no

jurisdiction to regulate the other environmental effects of the proposed facility in

this PSD proceeding.


                                          -7-
#26290, #26293

[¶20.]       Citizens also argue that the Board and DENR abused their discretion

in determining that an EIS was not necessary. Under SDCL 34A-9-4, “an EIS is

optional, not mandatory.” In re SDDS, Inc., 472 N.W.2d 502, 507 (S.D. 1991). See

also In re S.D. Water Mgmt. Bd. Approving Water Permit No. 1791-2, 351 N.W.2d

119, 124 (S.D. 1984) (concluding that the EIS statute “evidence[s] a legislative

intent not to require an environmental impact statement every time [the] Board

rules on a . . . permit”). “Since the [decision to order an EIS] is one which lies in the

discretion of the agency, we can reverse its decision only if it reflects a clearly

unwarranted exercise of discretion.” In re SDDS, 472 N.W.2d at 507.

[¶21.]       The purpose of an EIS is “to inform the public and other public

agencies as early as possible about proposed actions” and “to solicit comments which

will assist the agency in determining the environmental consequences of the

proposed action.” SDCL 34A-9-6. These purposes were addressed in the Board’s

and DENR’s administrative process. That process included a detailed technical

review of Hyperion’s permit application, publication of the proposed action, DENR’s

solicitation and response to public comments, and consideration of the evidence

presented at the contested case hearings.

[¶22.]       DENR first performed an extensive technical review of Hyperion’s

application. After issuing public notices of the application and DENR’s proposed

action, DENR then received extensive commentary from the public, other agencies,

and environmental groups. Those commenting included the United States

Department of Interior, the United States Environmental Protection Agency (EPA),

and Plains Justice. DENR then considered the comments, issued responses, and


                                           -8-
#26290, #26293

made changes to the proposed permit. In its response to comments, DENR noted

that an EIS was unnecessary because “the procedural and substantive

requirements for obtaining an air quality permit provide the agency [with]

information that is functionally equivalent to the relevant information that would

be provided by an environmental impact statement.” (Emphasis added.)

[¶23.]       A public contested hearing was then held before the Board. The Board

considered the filed comments and DENR’s responses. The Board heard the

extensive evidence for and against the project. The Board considered alternatives

to Hyperion’s proposed equipment. The Board assessed the facility’s proposed

design and operational limits. The Board reviewed Hyperion’s additional impacts

analysis and determined that “no adverse impacts are expected to air quality,

visibility, or soils and vegetation as a result of [Hyperion’s proposed facility] and

associated commercial, residential, and industrial growth.”

[¶24.]       The Board also considered expert testimony on the need for an EIS.

Kyrik Rombough, DENR’s Natural Resources Engineering Director, was the lead

permit writer for the PSD permit program. Since beginning work at DENR, he had

processed and reviewed hundreds of air quality permits. Rombough testified that

DENR’s review of Hyperion’s permit application indicated an EIS was unnecessary.

Colin Campbell, Hyperion’s expert, oversaw air permitting projects and worked

with state agencies in implementing air permitting programs. He testified that,

when he was involved in Arizona’s and Utah’s air permitting processes, neither

state required EISs. He also testified that, based on his experience, EISs were not

typically prepared for similar projects, such as refinery expansions.


                                           -9-
#26290, #26293

[¶25.]         The federal EIS experience is also instructive. Under the National

Environmental Policy Act, EISs are generally mandated. 42 U.S.C.A. § 4332(c)

(West 2012). Nevertheless, federal air quality permits, including PSD permits, are

exempt from the mandate. 15 U.S.C.A. § 793(c)(1) (West 2012); 40 C.F.R. §

124.9(b)(6). See also In re Knauf Fiber Glass, 8 E.A.D. 121, 35 (EAB 1999). We

acknowledge that the federal statutory exemption does not control the discretionary

decision under SDCL 34A-9-4. But the federal law’s exemption does suggest that

Congress determined EISs are generally not required to protect the environment in

determining entitlement to PSD air quality permits.

[¶26.]         Finally, we note the record reflects that other environmental concerns

typically addressed in an EIS will not be overlooked. Although an EIS was not

prepared in the air quality permitting portion of this regulatory proceeding, the

record indicates that other EIS concerns will be addressed in other regulatory

proceedings that are necessary to construct and operate the proposed facility. In

denying the Citizens’ request for an EIS, the Secretary of DENR explained:

               We [ ] disagree with your assertions that other
               environmental concerns, such as water withdrawals, water
               use, groundwater, surface water, water quality, stormwater,
               waste disposal, wastewater, and spill response, will not be
               considered. While these issues are not addressed in the
               draft [PSD permit] that is currently under review, those other
               environmental issues will be fully considered when Hyperion
               complies with a host of other permitting and regulatory
               processes, such as a water right permit, discharge permits,
               waste disposal permit, etc. . . . 6


6.       At oral argument, the Court was informed that Hyperion will most likely be
         required to obtain a federal “404 permit” for the proposed facility’s surface
         water discharges. The Court was further informed that, in most
         circumstances, the United States Army Corp of Engineers must prepare
                                                              (continued . . .)
                                            -10-
#26290, #26293


[¶27.]         In sum, the Board’s and DENR’s decisions to deny the requests for an

EIS were supported by DENR’s technical review of Hyperion’s application and other

agency and public comments; DENR’s response to those agency and public

comments; and the testimony and environmental evidence considered in the

administrative process. 7 We conclude that the Board and DENR did not abuse their

discretion in denying the requests for an EIS.

     2. Validity of the Permit

[¶28.]         Citizens point out that original permit condition 2.1 imposed a

commence construction deadline of February 20, 2011. Citizens argue that the

permit expired because Hyperion did not commence construction or obtain an

extension before that initial deadline. Citizens also argue that because the

amended deadline ultimately adopted was not requested within the initial eighteen-

month period, the Board was without authority to authorize that amended deadline.

Citizens rely on the language of original permit condition 2.1, ARSD 74:36:09:02,

and 40 C.F.R. section 52.21(r)(2).

[¶29.]         The interpretation of a permit is analogous to the interpretation of a

contract or statute. “Contract and statutory interpretation are questions of law we

review de novo.” AFSCME Local 1025 v. Sioux Falls Sch. Dist., 2011 S.D. 76, ¶ 11,

809 N.W.2d 349, 352. “Administrative regulations are subject to the same rules of

         either an EIS or Environmental Assessment when determining whether to
         issue a 404 permit. See 33 C.F.R. § 336.1(b)(6).

7.       On appeal, Citizens have not contended that the Board erred in refusing any
         offered environmental evidence.

construction as are statutes.” WestMed Rehab, Inc. v. Dep’t of Soc. Servs., 2004 S.D.

104, ¶ 8, 687 N.W.2d 516, 518.

[¶30.]         Condition 2.1 imposed a commence construction deadline but allowed

extensions. Condition 2.1 provided:

               In accordance with ARSD 74:36:09:02, as referenced to 40 C.F.R.
               § 52.21(r)(2), the owner or operator shall commence construction
               within 18 months of the effective date of this permit. If
               construction is delayed or interrupted for a period of 18 months
               or more this permit becomes invalid. The owner or operator
               may apply, before the end of the 18-month period, to the
               Secretary [of DENR] for an extension. The Secretary may grant
               an extension after the owner or operator satisfactorily
               demonstrates that an extension is justified.

Condition 2.1 is premised upon ARSD 74:36:09:02, 8 which incorporates 40 C.F.R.

section 52.21(r)(2). 9

[¶31.]         There is no dispute that Hyperion did not commence construction by

February 20, 2011. Citizens’ first argument is that, even though Hyperion’s initial

extension application was filed within the eighteen-month time to commence



8.       ARSD 74:36:09:02 provides, that “the state’s definitions and requirements for
         the prevention of significant deterioration are those in 40 C.F.R. § 52.21 . . . .”

9.       40 C.F.R. section 52.21(r)(2) provides:

               Approval to construct shall become invalid if construction is not
               commenced within 18 months after receipt of such approval, if
               construction is discontinued for a period of 18 months or more,
               or if construction is not completed within a reasonable time.
               The Administrator may extend the 18-month period upon a
               satisfactory showing that an extension is justified. This
               provision does not apply to the time period between construction
               of the approved phases of a phased construction project; each
               phase must commence construction within 18 months of the
               projected and approved commencement date.

construction, the permit became invalid because the Board did not grant the

extension until after the initial eighteen-month period expired. 10 Citizens point out

that condition 2.1 and 40 C.F.R. section 52.21(r)(2) do not explicitly state that the

original permit remains in effect or that the permit’s expiration is stayed while the

Secretary considers a request for an extension. Thus, Citizens contend that when

the Secretary failed to grant an extension before the expiration of the initial

commence construction deadline, the original permit automatically expired,

precluding any amendment. 11 Citizens contend that the original and amended



10.   Hyperion and DENR argue that SDCL 1-26-28 extended the validity of
      Hyperion’s permit while the application for an extension was pending. SDCL
      1-26-28 provides:

             If a licensee has made timely and sufficient application for
             renewal of a license or a new license with reference to any
             activity of a continuing nature, the existing license, or a right to
             continue the activity, does not expire until the application has
             been finally determined by the agency and for ten days following
             receipt, or failure to accept delivery, of notice of such
             determination by the licensee.

      (Emphasis added.) A permit is a “license” for purposes of this statute. See
      SDCL 1-26-1(4). However, SDCL 1-26-28 did not apply to Hyperion’s
      application for the extension. Hyperion requested that condition 2.1 be
      amended to extend the construction deadline. Hyperion did not request a
      “renewal” or a “new” permit. See id.

11.   Citizens rely on Sierra Club v. Franklin County Power of Illinois, LLC, 546
      F.3d 918 (7th Cir. 2008). However, in Franklin County, no extension
      application had been filed. The dispute was whether a permittee had
      “commenced construction” by entering a construction memorandum and
      conducting engineering research and excavation work. Id. at 929-31.
      Franklin County does not support Citizens’ argument that PSD permits
      automatically expire even though a timely extension application is pending.

      Citizens also argue that Hyperion was required to request a temporary
      extension when it appeared that DENR would be unable to act on the
                                                         (continued . . .)
                                       -13-
#26290, #26293

permits cannot be upheld because “it is beyond the role of the courts to supply

omitted language” authorizing PSD permits to remain in effect until the Secretary

rules on extension requests.

[¶32.]       The language of 40 C.F.R. section 52.21(r)(2) and condition 2.1 cannot,

however, be read to require an automatic expiration of the PSD permit if a timely

application for extension is pending and the Secretary is unable to rule on the

application within the original time limit. It must be noted that 40 C.F.R. section

52.21(r)(2) does not impose any time limits for filing extension requests, and

condition 2.1 allowed the extension request to be filed any time before the eighteen-

month period expired. It must also be noted that both the condition and the rule

contemplate that the Secretary must have time to consider additional evidence

before deciding extension requests. Condition 2.1 provides that the Secretary may

grant an extension only “after the owner or operator satisfactorily demonstrates

that an extension is justified.” (Emphasis added.) Similarly, 40 C.F.R. section

52.21(r)(2) authorizes extensions only “upon a satisfactory showing that an

extension is justified.” (Emphasis added.) Thus, the condition and rule allow

extension requests to be filed up to the last day of the eighteen-month period, but

require the extension to be preceded by a satisfactory showing that the extension is

justified. We conclude the rule and condition necessarily contemplated that a final

decision may not necessarily be made within the initial deadline.

(. . . continued)
         requested extension within the initial eighteen-month deadline. We decline
         to consider this argument. Citizens presented no authority allowing DENR
         to grant temporary extensions without determining whether the extension
         was justified.

                                         -14-
#26290, #26293

[¶33.]       Indeed, it may be impossible to obtain a final ruling on an extension

request within the original deadline. As this case demonstrates, extension requests

may be complicated matters that require extensive time to administratively resolve.

Because an extension request seeks to amend a condition of a PSD permit, the

request must be processed under the same administrative procedure as a permit

application, which requires lengthy administrative proceedings. And if the initial

permit is on appeal, the administrative process must be preceded by filing a motion

with the reviewing court to seek the permit’s return to the Board to allow the

consideration of additional evidence. See Jundt v. Fuller, 2007 S.D. 62, ¶ 7, 736

N.W.2d 508, 512. If the reviewing court grants the motion, the permit holder must

then apply for an extension with the Secretary. Next, the Secretary must

recommend an amended permit, publish the proposed permit, and provide time for

a contested case hearing. See ARSD 74:36:09:03. Finally, interested parties may

litigate the matter before the Board. Considering the many months necessary to

complete this administrative process, it would be impossible to obtain a final ruling

on many extension requests within the initial eighteen-month period, even requests

filed early within the initial eighteen-month period.

[¶34.]       In this case, Hyperion submitted its initial extension application on

June 23, 2010. During its review of the application, DENR requested additional

information from Hyperion. DENR’s draft amended permit was not made available

for public comment until February 14, 2011, six days before the initial deadline was

to expire. DENR received over 350 public comments on the draft amended permit,

and DENR responded to those comments when issuing its final proposed amended


                                         -15-
#26290, #26293

permit. A contested case hearing was requested, and on March 21, 2011, the Board

scheduled a contested case proceeding for July 25, 2011, over thirteen months after

the initial extension request. The Board heard closing arguments on September 15,

2011, and issued its findings of fact and conclusions of law on September 16, 2011.

In total, the administrative process took almost fifteen months to complete, not

counting the time necessary to resolve appeals of the Board’s decision in the courts.

[¶35.]       Considering the realities of environmental permitting, Citizens’

interpretation of 40 C.F.R. section 52.21(r)(2) and condition 2.1 leads to an absurd

result. Because of the lengthy time necessary to obtain a final ruling on an

extension request in complicated cases, few, if any, such extension requests could be

considered under Citizens’ interpretation. Citizens’ interpretation of condition 2.1

would abrogate what condition 2.1 and 40 C.F.R. section 52.21(r)(2) expressly

authorize: an opportunity to obtain an extension after a timely application and a

full consideration by the Secretary and the Board of conflicting evidence relating to

the request. We conclude that the permit did not become invalid solely because the

Secretary was procedurally unable to grant a final extension within the original

eighteen-month period. We do not interpret language to reach an absurd result.

State v. Robert, 2012 S.D. 27, ¶ 10, 814 N.W.2d 122, 125.

[¶36.]       Citizens, however, contend that allowing the Secretary an indefinite

timeframe to rule on an extension request thwarts the purposes of the deadline.

According to DENR’s and Hyperion’s experts, there are two reasons for the

eighteen-month deadline. First, the deadline ensures that BACT determinations

are current. See Ky. Mountain Power, LLC v. Energy & Env’t Cabinet, No. DAQ-


                                         -16-
#26290, #26293

29109-039, 2009 WL 6214729, at *38 (Ky. Envtl. & Pub. Protection Cabinet Dec. 1,

2009) (“[D]ecisions about pollution control methods and associated emissions

limitations are made based on the most current information possible.”). Second, the

deadline ensures that permit holders do not, by delay or inaction, obtain longer time

periods than allowed to build new facilities, thereby unnecessarily tying up a state’s

air resources and industrial growth rights.

[¶37.]       The additional time taken by the Secretary did not frustrate these

purposes. When preparing the draft amended permit, DENR reevaluated BACT

limits and reviewed new regulations, which ensured that the BACT determinations

were up to date. DENR also required modeling to ensure the proposed facility

would comply with new emission standards. Finally, there was no evidence that

Hyperion had tied up the State’s air resources or restricted any other competing

industrial growth.

[¶38.]       Citizens also argue that, even if the Board was authorized to grant

Hyperion’s initial extension application after the eighteen-month period had

expired, the finally adopted extension was invalid. Citizens contend that the finally

adopted extension was invalid because Hyperion did not make that particular

extension request before the initial eighteen-month deadline had expired. This

argument overlooks the nature of the finally adopted request in the context of the

required administrative proceedings.

[¶39.]       Hyperion’s initial June 2010 request for an August 20, 2012 extended

deadline was made within the original eighteen-month period. But the Secretary

did not act on Hyperion’s request until he issued a proposed draft amended permit


                                         -17-
#26290, #26293

and notice of opportunity for public comment on February 14, 2011. At that point,

the public notice comment period remained open until April 1, 2011, well after the

initial commence construction deadline would expire. On March 31, 2011, Hyperion

filed its comments to DENR’s draft amended permit. In those comments, Hyperion

requested that the deadline be extended to eighteen months after the amended

permit was ultimately issued. Hyperion indicated that it amended its request for

an extension “in light of the unpredictable timeline associated with the approval of

the amended permit.” Thus, Hyperion made a timely application for an extension;

Hyperion was aware that DENR was recommending that an extension be granted;

but the original deadline was expiring and substantial additional time would be

needed before Hyperion would receive a final determination on the extension

request. Under these circumstances, Hyperion’s amended request for an extension,

made within the proceeding to determine the initial extension request, was an

amendment that did not constitute a new and therefore untimely application. Cf.

Bitterroot River Protective Ass’n v. Siebel, 108 P.3d 518, 522, 524 (Mont. 2005)

(holding that amendments to substantially deficient water appropriation

applications constituted new applications because the “changes were so significant

that the amended applications bear[ed] little resemblance, if any, to the original

applications[,]” and therefore, the amendments did not relate back to the date of the

timely filed deficient applications).

[¶40.]       We conclude that DENR and the Board were not required to render a

final decision on the initial timely extension request within the initial eighteen-

month period. Further, the subsequent amendment to the request was made


                                         -18-
#26290, #26293

during the extension proceedings, and that amendment was not so different as to

constitute a new application. Therefore, Hyperion’s permit did not become invalid.

   3. Justification to Extend the Commence Construction Deadline

[¶41.]       Citizens argue that Hyperion did not sufficiently justify its request for

an extension of the commence construction deadline. Citizens contend that the

Board’s contrary determination was clearly erroneous. “For an agency finding of

fact to be clearly erroneous, a court must be definitely and firmly convinced, after

reviewing all the evidence, that the agency made a mistake.” McKibben v. Horton

Vehicle Components, Inc., 2009 S.D. 47, ¶ 11, 767 N.W.2d 890, 894. “However, we

defer to the agency on the credibility of a witness who testified live because the

agency ‘is in a better position . . . to evaluate the persuasiveness of [witness]

testimony.’” Id. (second alteration in original) (quoting Lends His Horse v. Myrl &

Roy’s Paving, Inc., 2000 S.D. 146, ¶ 15, 619 N.W.2d 516, 520). See also Burke v.

Butte Cnty., 2002 S.D. 17, ¶ 16, 640 N.W.2d 473, 478 (stating that “[the agency] is

entitled to weigh the credibility of the witnesses and is free to choose between

conflicting testimony”).

[¶42.]       In its 2011 findings of fact and conclusions of law, the Board found that

Hyperion presented satisfactory justification for the extension.

             The Board determines that the evidence submitted in support of
             Hyperion’s request for an extension of the commence
             construction deadline is justified given the economic recession,
             which caused delays in development of large capital projects
             such as [Hyperion’s proposed facility], the pending appellate
             process regarding the status of the permit, the recent discovery
             of the additional emission unit for [Hyperion’s proposed facility],




                                          -19-
#26290, #26293

             the coker quench water system, as well as the additional
             National Ambient Air Quality Standards for SO2 and NO2.

The record supports this finding.

[¶43.]       At the 2011 contested hearing, a Hyperion vice-president testified that

the recession affected Hyperion’s ability to begin constructing the facility. He also

indicated that the uncertainty of the permit’s status and the need to address two

new federal emission requirements justified an extension. The vice-president

finally indicated that Hyperion had recently identified a “coker quench” water

system as an additional emission source, and therefore, Hyperion needed an

extension to obtain an amended permit to include that emission source.

[¶44.]       Citizens, however, contend that Hyperion did not specifically identify

how the economic recession and the ongoing litigation affected Hyperion’s ability to

meet the commence construction deadline. Citizens also contend that Hyperion

contributed to the uncertainty of the permit’s status because Hyperion itself

appealed the BACT limit for the process heaters. Further, Citizens contend that

the two new federal emission requirements did not justify an extension because

those new requirements would not have applied if Hyperion had not requested to

amend its permit. Finally, Citizens contend that Hyperion had ample time to

correct the coker quench water system oversight before the initial deadline expired.

[¶45.]       Although Citizens cross-examined Hyperion’s vice-president regarding

the reasons for the extension, the Board was best suited to determine the credibility

of the vice-president and the weight to be given to his testimony. Further, Citizens

provided no contradicting testimony. Therefore, after reviewing the entire record,

we are not definitely and firmly convinced that the Board made a mistake. The

                                         -20-
#26290, #26293

Board did not clearly err in finding satisfactory justification for extension of the

commence construction deadline.

   4. Carbon Monoxide “Best Available Control Technology” Limit

[¶46.]       Large process heaters at Hyperion’s proposed facility will burn refinery

gas to heat equipment used in the refinery process. There is no dispute that a

carbon monoxide BACT limit is required for the heaters. The dispute is the

achievable BACT limit.

[¶47.]       ARSD 74:36:09:02 incorporates 40 C.F.R. section 52.21(b)(12), which

defines the “best available control technology” for limiting regulated pollutant

emissions at the proposed facility:

             Best available control technology means an emissions limitation
             (including a visible emission standard) based on the maximum
             degree of reduction for each pollutant subject to regulation . . .
             which would be emitted from any proposed major stationary
             source or major modification which the Administrator, on a case-
             by-case basis, taking into account energy, environmental, and
             economic impacts and other costs, determines is achievable for
             such source or modification through application of production
             processes or available methods, systems, and techniques,
             including fuel cleaning or treatment or innovative fuel
             combustion techniques for control of such pollutant. . . .

To establish a proper BACT limit for a permit under this rule, the proposed limit

must be shown to be both: 1) the maximum degree of reduction of a pollutant

subject to regulation (considering energy, environmental, and economic impacts and

other costs), and 2) achievable for such source. Id. A BACT limit is achievable if

the facility, when operating, is able to comply with that emission limit.

[¶48.]       DENR proposed the 0.007 lb/mmBtu BACT limit, which the Board

adopted. Hyperion argues that limit is not supported by evidence and is


                                          -21-
#26290, #26293

unachievable for its facility. Hyperion argues that a 0.010 lb/mmBtu limit is

supported by the evidence. Hyperion contends that the Board clearly erred in

adopting DENR’s proposed limit. We “give great weight to the findings of the

agency and reverse only when those findings are clearly erroneous in light of the

entire record.” Williams v. S.D. Dep’t of Agric., 2010 S.D. 19, ¶ 5, 779 N.W.2d 397,

400.

[¶49.]         Because a PSD permit must be issued before construction is initiated,

the achievable BACT limit is based on agency review of estimates and projections of

pollutants that will be emitted by the proposed facility. 12 These estimates and

projections are based on engineering analysis, computer modeling, and regulatory

data from other states and the EPA. DENR supported its proposed 0.007 lb/mmBtu

limit by evidence of other facilities’ emission limits. The Board adopted DENR’s

proposed 0.007 lb/mmBtu limit, finding that DENR’s proposed limit was based on

performance testing and other permits. The Board also found that the 0.007

lb/mmBtu limit was achievable.

[¶50.]         Hyperion argues that the Board clearly erred in relying on DENR’s

evidence. Hyperion contends that the other facilities and their carbon monoxide

emission limits were not comparable to Hyperion’s proposed facility.

[¶51.]         Kyrik Rombough, DENR’s Natural Resources Engineering Director,

testified at the 2009 hearing. He testified that he converted emission limit


12.      After a PSD permit is issued and the facility is constructed, the facility’s
         operator must apply for a “Part 70” (a/k/a “Title V”) operating permit within
         the first year of operation. ARSD 74:36:05:08. It is not until that time that
         actual emissions data from performance tests exist to demonstrate
         compliance with emissions limits. ARSD 74:36:05:06.

                                           -22-
#26290, #26293

measurements used by the reviewed facilities to the “lb/mmBtu” emission limit

measurement imposed in this permit. Rombough indicated that after the

conversion, the other facilities’ emission limits were equivalent to the 0.007

lb/mmBtu limit. Hyperion challenges the comparison of the emission limit

measurements from other facilities.

[¶52.]       Hyperion first challenges DENR’s reliance on the Baytown refinery in

Texas. Hyperion points out that Baytown was an ethylene production facility,

unlike Hyperion’s proposed oil refinery. Hyperion also points out that Baytown’s

carbon monoxide BACT limit was revised and is currently less stringent than

Hyperion’s proposed 0.010 lb/mmBtu limit. However, Rombough testified that the

fuels burned in Baytown’s process heaters were similar to Hyperion’s proposed

fuels. Rombough further testified he had verified with the Texas permitting agency

that Baytown’s achievable limit was equivalent to a 0.007 lb/mmBtu limit.

[¶53.]       Hyperion also challenges DENR’s reliance on the CENCO refinery.

Hyperion contends that this facility never operated, and therefore, its ability to

achieve a limit equivalent to 0.007 lb/mmBtu was not substantiated through

performance tests. Rombough acknowledged that CENCO never operated.

Rombough, however, indicated that CENCO’s limit—a limit that converted to a

0.007 lb/mmBtu limit—was based on two operational facilities (TOSCO and All Air

Products) whose permits required a limit equivalent to 0.007 lb/mmBtu. Rombough

also testified that he had analyzed a TOSCO performance test, which indicated that

TOSCO had complied with an emission limit equivalent to the 0.007 lb/mmBtu

limit. Although Hyperion relies on its expert, who opined that these facilities were


                                         -23-
#26290, #26293

not comparable because of differences in the refinery fuel gases, the Board was best

suited to adopt the expert’s testimony that the Board believed was more persuasive.

[¶54.]         Hyperion finally contends that the Board erred in relying on the Big

West refinery because it was never permitted or built. However, in Big West’s

application for a PSD permit, the applicant itself asserted that a 0.007 lb/mmBtu

limit was achieved by process heaters burning refinery gas in testing conducted by

California. Although Big West never operated, the evidence reflects that the limit

was determined by performance testing. Again, the Board was in the best position

to accept or reject the comparability of the evidence with respect to Big West. 13

[¶55.]         We also note that Hyperion’s permit was reconsidered by the Board in

the 2011 contested case proceedings. DENR had reevaluated Hyperion’s BACT

limit to ensure that it was current. DENR considered updated data, new permits,

and new regulations regarding BACT limits. Both DENR and the Board reaffirmed

the 0.007 lb/mmBtu limit in light of new developments regarding carbon monoxide

BACT limits.

[¶56.]         Hyperion, however, contends that publication of new EPA regulations

before the 2011 hearing substantiated its inability to achieve a 0.007 lb/mmBtu

limit. 14 Hyperion points out that some of the EPA regulations, using a different



13.      In its findings, the Board acknowledged that Big West’s application was
         withdrawn and no performance data existed for that facility. The Board also
         acknowledged that the EPA “cautions against the use of cancelled permits for
         BACT analysis.” The Board, however, did not indicate that the actual
         performance testing used in Big West’s application was suspect.

         emissions data provided in the amended permit proceeding is not reviewable

numerical limit, indicate upper predictive carbon monoxide limits that were higher

than the limit adopted by the Board. Hyperion argues that the DENR’s reliance on

the EPA’s lower limits was misplaced because the lower limits were averages and

an average emission level does not indicate an “achievable” limit over an extended

period of operation.

[¶57.]       DENR, however, explained that when the new EPA background

testing data was converted for comparison purposes, it revealed 423 test results at

new facilities with limits less than the EPA average. Therefore, in DENR’s view,

the new regulations supported a 0.007 lb/mmBtu BACT limit. Further, Rombough

testified that the EPA employed a limits testing method that differed from

Hyperion’s method. The Board adopted DENR’s view, finding that Hyperion’s limit

“contain[ed] both filterable and condensable particulate matters, whereas EPA’s

new regulation only include[d] filterable material.”

[¶58.]       We acknowledge that Hyperion presented testimony supporting its

proposed limit. We also acknowledge that some of DENR’s comparative evidence

was subject to different interpretations. But ultimately, the comparability of other

facilities involved conflicting evidence. As previously noted, under these

         because Hyperion did not specifically raise the issue at the 2011 contested
         hearing. However, the carbon monoxide emission limit remained in issue
         since the 2009 hearing. In fact, Hyperion’s appeal of the imposed limit
         following the 2009 hearing was still pending at the time of the 2011 hearing.
         Further, Hyperion gave notice that it was continuing to contest the 2009
         decision, and Hyperion submitted evidence on this contested issue in its
         September 2010 letter responding to DENR’s request that Hyperion review
         the EPA’s evaluations. Therefore, the issue was raised at the Department
         level and may be reviewed by this Court. See Stuckey v. Sturgis Pizza Ranch,
         2011 S.D. 1, ¶ 19 n.3, 793 N.W.2d 378, 386 n.3.

circumstances, we “defer to the agency on the credibility of a witness who testified

live because the agency ‘is in a better position . . . to evaluate the persuasiveness of

[witness] testimony.’” McKibben, 2009 S.D. 47, ¶ 11, 767 N.W.2d at 894 (second

alteration in original) (quoting Lends His Horse, 2000 S.D. 146, ¶ 15, 619 N.W.2d at

was achievable for Hyperion’s project.
