The Peace River/Manasota Regional Water Supply Authority (the Authority), joined by three counties and the Sierra Club, appeals the final order issued by the Department of Environmental Protection (DEP) that granted various permits to IMC Phosphates Company (IMC) to operate a new phosphate mine. The Authority raises three grounds for review: (1) that the Administrative Law Judge (ALJ) erred when he determined that the Authority lacked standing to challenge IMC’s permit application; (2) that the ALJ erred by refusing to consider evidence of the cumulative impact of IMC’s proposed mining activities on the Peace River itself and
*1081
the Peace River basin as a whole; and (B) that various procedural irregularities occurred that rendered portions of the proceedings fundamentally unfair. As to ground one, we hold that the Authority did have standing to challenge IMC’s permit application and to prosecute this appeal, and we write to explain our reasoning. As to ground two, we affirm and write to explain why, given the plain language of the statutory provision at issue and the facts as found by the ALJ, such a conclusion is required. Finally, as to ground three, we affirm for the reasons explained in our companion opinion in
Charlotte County v. IMC Phosphates Co.,
No. 2D06-3848,
Background
The events culminating in this appeal began in 2000 when IMC filed a Consolidated Development Application with DEP seeking an environmental resource permit that was required before it could begin construction of a new phosphate mine on a 20,675-acre tract of land. At the same time, IMC sought approval of a conceptual reclamation plan, which would govern IMC’s obligations to reclaim the wetlands after mining. After DEP issued a notice of intent to issue the permits in January 2003, the Authority, Charlotte County, Lee County, Alan Behrens, and DeSoto Citizens Against Pollution, Inc., filed petitions for formal administrative proceedings to challenge the issuance of the permits. 1 All of the petitions were subsequently consolidated.
In 2004, in response to certain DEP rulings concerning other pending permit applications, IMC filed an amended application that reduced the size of the proposed mining project to 4197 acres. After DEP issued revised notices of intent to issue the permits, Sarasota County filed a petition in opposition to the revised project. All of the administrative proceedings relating to this project were subsequently consolidated and set for hearing.
Prior to the hearing, IMC filed what was essentially a motion in limine seeking to exclude any evidence of the cumulative impacts of this project and others on the Peace River and the Peace River basin based on the provisions of section 373.414(8)(b), Florida Statutes (2004). The ALJ granted this motion, thus precluding the Authority from presenting evidence concerning the cumulative impacts of all of the previous and pending unrelated mining activity in the Peace River basin and the potential “big picture” incremental impact of IMC’s proposed project. In light of this ruling, the Authority proffered its cumulative impacts evidence during the hearing.
Also prior to the hearing, IMC filed a “Motion to Challenge Standing of All Petitioners,” alleging as to the Authority that it did not have standing to challenge the issuance of the permit because its substantial interests would not be affected if the permit issued. The parties then stipulated to the ALJ considering the standing issue during the administrative hearing on the merits. 2
After eight weeks of testimony, the ALJ issued his recommended order. In that *1082 order, the ALJ found that the Authority did not have standing because its substantial interests were not affected by the order; however, the ALJ noted that the issue was moot because the Authority had fully participated in all the proceedings. The ALJ also reaffirmed his ruling that IMC was not required to address the cumulative impacts of the project under the plain language of section 373.414(8)(b). In addition, the ALJ recommended that DEP grant IMC’s permit application but only after implementing a series of additional permit conditions that would strengthen the environmental protections. After further proceedings not relevant to the issues discussed in this opinion, DEP adopted the majority of the recommended order, including the ALJ’s rulings on standing and the admissibility of the evidence concerning cumulative impacts. Based on the ALJ’s findings of fact and conclusions of law and DEP’s own analysis of the law, DEP granted the permits sought by IMC but with the additional conditions recommended by the ALJ. The Authority then brought this appeal of DEP’s ruling.
Standard of Review
In an appeal from final administrative action, this court reviews the findings of fact made by the ALJ and adopted by the administrative agency to determine whether they are supported by competent, substantial evidence. § 120.68(7)(b), Fla. Stat. (2004);
see also Pauline v. Lee,
The Authority’s claims concerning both standing and the cumulative impacts evidence are claims concerning statutory interpretation and the application of the statutes to the facts of the case. Thus we review the interpretation of the statutory language de novo, but we must defer to the ALJ’s factual findings that are supported by competent, substantial evidence when applying the statute to the facts.
Standing in the Proceedings Below
The Authority first contends that the ALJ and DEP erred by determining that the Authority did not have standing in the administrative proceedings. While this argument is technically moot since the ALJ allowed the Authority to fully participate below, we address the issue because it is raised by IMC in every permitting case and because the ALJ’s and DEP’s conclusions on this issue are incorrect.
As a general proposition, “[sjtanding is a legal concept that requires
*1083
a would-be litigant to demonstrate that he or she reasonably expects to be affected by the outcome of the proceedings, either directly or indirectly.”
Hayes v. Guardianship of Thompson,
As all of the parties admit, chapter 120 does not actually employ the word “standing,” but the statutory test used is substantially its equivalent. Under the statutory language, a hearing is provided pursuant to section 120.569(1) “in all proceedings in which the substantial interests of a party are determined by an agency.” Thus the concept of “standing” in an administrative proceeding depends on whether the particular entity at issue qualifies as a “party.” Section 120.52(12)(b) defines a “party” as “[a]ny other person who, as a matter of constitutional right, provision of statute, or provision of agency regulation, is entitled to participate in whole or in part in the proceeding, or whose substantial interests will be affected by proposed agency action. ...”
Here, the undisputed record evidence shows that the Authority is a regional water supply authority that supplies potable water to the residents of four counties. The Peace River is the Authority’s sole source of water. Horse Creek is a tributary of the Peace River, and Horse Creek supplies approximately fifteen percent of the fresh water to the portion of the Peace River from which the Authority withdraws water. The Authority has a water use permit (WUP) from the Southwest Florida Water Management District that both gives the Authority the right to withdraw water from the Peace River and sets conditions on those withdrawals. Thus, as an entity possessed of a legal right to withdraw water from the Peace River, the Authority inarguably has a substantial interest in the river’s environmental integrity, and this interest could be injured by changes in the flow of Horse Creek into the Peace River.
See Royal Palm Square Ass’n v. Sevco Land Corp.,
Further, the potential injury asserted by the Authority is of a type or nature that the administrative proceeding at issue is designed to protect. Chapter 373 deals *1084 with the protection and conservation of the water resources of this State. The purpose and scope of the administrative proceeding at issue were to ensure that IMC’s proposed activities would not adversely affect the existing water resources or that any adverse effects would be sufficiently mitigated. Thus the interests asserted by the Authority fall squarely within the scope and purpose of the interests that chapter 373 is designed to protect. Accordingly, the Authority was properly a “party” under section 120.52(10) and therefore had “standing” in this proceeding, and the ALJ and DEP erred in ultimately finding otherwise.
In this appeal, IMC argues that while the Authority properly alleged standing, it “failed in its proof.” IMC contends that because the ALJ and DEP found that there would be no adverse impacts to Horse Creek from the mining activities, the Authority failed to establish that its substantial interests would be affected. However, IMC misunderstands the issue to which the proof is directed.
IMC is correct that if standing is challenged during an administrative hearing, the petitioner must offer evidence to prove that its substantial rights could be affected by the agency’s action.
See Agrico,
IMC also argues that the Authority lacked standing because it could not show that its substantial interests might reasonably be affected by IMC’s activities along Horse Creek because the measuring gauge that determines the Authority’s right to draw water from the Peace River is upstream from the confluence of Horse Creek and the Peace River. However, this argument ignores the fact that the Authority actually withdraws water from the Peace River downstream from Horse Creek. Thus, while the Authority’s right to draw water may not depend on the health of Horse Creek, the Authority presented unrebutted evidence that its ability to draw water may well depend on that. 3 In addition, the Authority presented unre-butted evidence that the terms of its WUP require it to monitor the health of the Peace River downstream from its confluence with Horse Creek and that changes *1085 in the Peace River’s downstream health could affect the Authority’s right to withdraw water under its WUP. In light of this unrebutted evidence, IMC’s argument about the location of the measuring station has no merit.
The cases cited by IMC in support of its position that the Authority has no standing are easily distinguishable. In
Florida Chapter of the Sierra Club v. Suwannee American Cement Co.,
Here, unlike in those cases, the Authority has alleged specific injuries to its own rights, and those injuries are exactly the type of injuries intended to be addressed in the administrative proceeding at issue. Thus the Authority properly established standing before the ALJ, and the ALJ’s finding to the contrary, which was adopted by DEP, is erroneous. This error is not moot because the standing issue is raised by IMC in every administrative proceeding; however, no remand is necessary in this case because the ALJ permitted the Authority to fully participate in the proceedings below.
Standing on Appeal
In addition to challenging the Authority’s standing at the administrative hearing, IMC also challenges the Authority’s standing to prosecute this appeal, arguing that the Authority has no standing to appeal because it was not “advei'sely affected” by DEP’s actions. IMC correctly points out that section 120.68(1) permits judicial review only to “[a] party who is adversely affected by final agency action.” However, IMC’s argument that the Authority was not “adversely affected” is incorrect.
As a regional water authority, the Authority has the statutory responsibility “to meet the water needs of rapidly urbanizing areas in a manner which will supply adequate and dependable supplies of water where needed without resulting in adverse effects upon the areas from whence such water is withdrawn.” § 373.196(1). In keeping with this statutory responsibility, the Authority’s WUP imposes obligations on the Authority to monitor the environmental health of the Peace River downstream of its confluence with Horse Creek and the WUP conditions the Authority’s continued rights to withdraw water on the continuing adequate environmental health of the river. Because the permits issued by DEP allow IMC to alter the flow of Horse Creek, which may in turn alter the health of the Peace River, if those permits were improperly issued, the Authority will be adversely affected. Therefore, the Authority has standing to prosecute this appeal.
See Osceola County v. St. Johns River Water Mgmt. Dist.,
*1086 In the alternative, IMC argues that the Authority cannot bring this appeal because the ALJ and DEP concluded that IMC’s mining activities would not have any adverse effects on the Peace River. Thus, according to IMC, the Authority was not “adversely affected” by the agency action. However, interpreting section 120.68(1) in this manner would result in a situation in which a party who unsuccessfully challenged a permit application under section 373.414 could never appeal a final order issued by DEP because the permit cannot issue if there are adverse effects that are not mitigated. Because the Authority presented evidence that supported its position that it would be adversely affected if the permit was issued, the determination of whether those permits were properly issued necessarily includes appellate review. Thus, on these facts, the Authority has standing to appeal the ALJ’s and DEP’s rejections of its evidence, and its standing continues until the appellate process is tapped out.
Cumulative Impacts Evidence
Turning to the substantive issue, the Authority contends that the ALJ and DEP erred by refusing to consider its proffered evidence concerning the cumulative impacts of phosphate mining on Horse Creek and the Peace River. The Authority contends that the ALJ was required to consider this evidence pursuant to section 373.414(8)(a). DEP contends that the ALJ was not required to consider such evidence because the project fell within the “exception” to section 373.414(8)(a) found in section 373.414(8)(b). Given the factual findings of the ALJ in this case, we are constrained to agree with DEP.
Section 373.414(8)(a) requires DEP to consider the cumulative impact of regulated activities that will occur in wetlands when determining whether to issue a permit for mining activities. However, section 373.414(8)(b) limits the circumstances under which section 373.414(8)(a) applies. Section 373.414(8)(b) provides:
If an applicant proposes mitigation within the same drainage basin as the adverse impacts to be mitigated, and if the mitigation offsets these adverse impacts, the governing board and department shall consider the regulated activity to meet the cumulative impact requirements of paragraph (a).
(Emphasis added.) Under the plain language of section 373.414(8)(b), DEP must consider evidence of cumulative impacts either when the proposed mitigation is not in the same drainage basin as the adverse impacts or when the proposed mitigation does not offset the adverse impacts. If the proposed mitigation is in the same drainage basin and if the proposed mitigation offsets the adverse impacts, the cumulative impacts test is deemed satisfied as a matter of law and DEP need not consider any evidence of cumulative impacts.
Here, the parties do not dispute that IMC’s proposed mitigation is in the same drainage basin as the regulated activity. The only question is whether the proposed mitigation offsets the adverse impacts of IMC’s activities. The ALJ specifically found based on the testimony of IMC’s experts that IMC’s activities would not result in any adverse impacts postmitigation, and DEP adopted this finding. To the extent that this finding constitutes a factual finding that no adverse impacts will remain postmitigation, it is supported by competent, substantial evidence in the record. To the extent that DEP has found IMC’s mitigation efforts sufficient to support the issuance of the permit based on the factual finding that no adverse impacts will remain postmitigation, DEP has properly exercised its statutory discretion under section 373.414(l)(b) to determine whether the proposed mitigation is suffi-

See 1800 Atl. Developers v. Dep’t of Envtl. Regulation, 552
So.2d 946, 955 (Fla. 1st DCA 1989) (analyzing the statutory predecessor to section 373.414(l)(b) and holding that “[i]t is the responsibility of DER ... to establish mitigative measures acceptable to it under the statute” and “to define mitigative measures that would be sufficient to offset the perceived adverse effects of the dredging and filling contemplated by the project”);
see also Save Anna Maria, Inc. v. Dep’t of Transp.,
In this appeal, the Authority argues that section 373.414(8)(b) should be interpreted to mean that the mitigation must “fully offset” the adverse impacts created by IMC’s mining activities and that IMC did not establish that its proposed mitigation would fully offset the adverse impacts. This argument fails for two reasons.
First, this court is not permitted to add words to a statute that were not placed there by the legislature.
See Hayes v. State,
Second, even if we were to interpret the statute as suggested by the Authority, we would nevertheless be compelled to affirm. Section 373.414 does not require a permit applicant to mitigate every potential impact to waters, wetlands, and wildlife — it must only mitigate adverse impacts. Moreover, the focus of wetlands reclamation activities after phosphate mining must be on whether those activities “maintain or improve the water quality and the function of the biological systems present at the site prior to the commencement of mining activities.” § 373.414(6)(b). Here, the ALJ found, based on competent, substantial evidence, that there would be no postmitigation adverse impacts from IMC’s activities on either water quality or the function of the biological systems at issue, and DEP adopted this finding. Thus DEP implicitly ruled that IMC’s proposed mitigation “fully” offset the adverse impacts of its pro *1088 posed activities. Therefore, even under the Authority’s rewritten version of the statute, IMC was not required to present evidence of cumulative impacts.
It appears that the Authority’s real argument on this issue is that the ALJ’s finding of no adverse impacts was not supported by the evidence presented by IMC. The Authority points to testimony and evidence that established that the streamflow in Horse Creek would be reduced both during mining and after reclamation. However, there was also clear testimony that these reduced streamflows would be so small that they would not be adverse to the waters, wetlands, and wildlife at issue. The ALJ credited this testimony rather than the contrary evidence presented by the Authority, and this testimony supported the ALJ’s finding that the “function of the biological systems” would be fully restored. We have meticulously examined the voluminous record on appeal, and we have determined that there is ample evidence and counter-evidence on this issue that could have supported a ruling either way. Because it is solely the province of the ALJ to make credibility determinations and resolve issues of fact based on those determinations, we must defer to this factual finding.
Also, contrary to the Authority’s arguments in this appeal, this result does not create a “de minimis” exception to the cumulative impact rule in contravention of
Florida Power Corp. v. State, Department of Environmental Regulation,
In the absence of a finding that IMC’s activities would result in some unmitigated adverse impacts, IMC was not required to put forth, nor was DEP required to consider, evidence of cumulative impacts under section 373.414(8)(b). As a result, the ALJ did not err in excluding the Authority’s proffered evidence of cumulative impacts, nor did DEP err in refusing to consider the Peace River Cumulative Impacts Study.
That said, however, we agree with the Authority and the Fifth District in
Sierra Club v. St. Johns River Water Management District,
In addition, we recognize that protecting the environment is always a laudable goal, and had we been sitting as the trier of fact, our findings of fact might have been different from those ultimately made by the ALJ and adopted by DEP. However, the legislature has stated that “[t]he extraction of phosphate is important to the continued economic well-being of the state and to the needs of society.” § 378.202(1), Fla. Stat. (2004). In an effort to balance the competing interests of the mining industry and the environment, the legislature has encouraged DEP to work with phosphate companies to develop viable plans to mine the phosphate and then reclaim those lands postmining. It is not within our province to challenge the priorities set by the legislature or to judicially amend the statutes adopted by it in furtherance of those priorities. Therefore, given the plain language of section 373.414(8)(b) and the findings of fact made by the ALJ and adopted by DEP, we are compelled to affirm on this issue.
Conclusion
In conclusion, we hold that the Authority had standing to challenge IMC’s permit application before the ALJ and DEP and that it had standing to appeal the final order that granted that application. However, because the Authority was allowed to fully participate in all the proceedings, we need not reverse on that basis. On the substantive grounds raised by the Authority, we affirm.
Affirmed.
Notes
. Hardee County also initially challenged the issuance of the permits; however, it dropped its opposition before the administrative hearing.
. Ordinarily, standing is a threshold issue that should be disposed of before addressing the merits of the case. However, we can appreci-ale that in this instance the facts related to the merits needed to be developed to a certain degree before standing could be adequately addressed. Thus it appears that judicial economy was served by this procedure in this case.
. For example, the Authority presented evidence that there are days when the flow of the Peace River at the measuring station is sufficient to give the Authority the right to withdraw water from the river but the flow at the Authority’s intake structure is insufficient to prevent brackish water from the Charlotte Harbor estuary from backing up into the river. When that occurs, the Authority does not have the ability to withdraw water, even though it may have the right to do so, because the Authority does not have the facilities necessary to treat brackish water. The Authority posited that if the flow of Horse Creek into the Peace River was reduced, the number of days when brackish water would prevent the Authority from withdrawing water would increase.
