MCFADDEN, Judge.
These appeals and cross-appeals arise from a petition for administrative hearing Georgia River Network and American Rivers (the “River Groups”) filed to challenge a buffer variance the Director of the Environmental Protection Division (“EPD”) of the Georgia Department of Natural Resources (“DNR”) (the “Director”) issued to the Grady County Board of Commissioners (the “County”) under Georgia’s Erosion and Sedimentation Act in connection with the County’s plans to construct a 960-acre fishing lake. The buffer variance permits the County to encroach upon the 25-foot vegetative buffer the Erosion and Sedimentation Act requires adjacent to streams on the site. The Administrative Law Judge (“ALJ”), after rejecting two challenges to her jurisdiction, reversed the variance, concluding that it failed to account for buffers required for wetlands on the site. In parallel proceedings for judicial review, the Superior Court of Fulton County (the “Fulton Court”) and the Superior Court of Grady County (the “Grady Court”) (collectively, the “Superior Courts”) issued orders reversing the ALJ’s decision.
In Case Nos. A14A0215 and A14A0272, the River Groups appeal from the Fulton Court and Grady Court orders, respectively, arguing that the Superior Courts erred in finding that the ALJ lacked jurisdiction and in concluding as to the merits that the Erosion and Sedimentation Act requires a 25-foot buffer only along the banks of state waters with vegetation wrested by normal stream flow or wave action. In Case Nos. A14A0273 and A14A0274, the Director and County, respectively, cross-appeal the Grady Court order. Although they do not contest the reversal of the ALJ decision, they argue that the Grady Court erred by finding “no obvious error” in the ALJ’s standing determination.
We conclude that the River Groups challenged an “order or action” of the Director; that the River Groups had standing; and that the Superior Courts erred in determining that the buffer requirement applies only to state waters with wrested vegetation. We therefore reverse the superior courts’ judgments.
[382]*3821. Statutory background and procedural history.
This court conducts a de novo review of claimed errors of law in a superior court’s appellate review of an ALJ’s decision. Upper Chattahoochee Riverkeeper v. Forsyth County, 318 Ga. App. 499, 501-502 (734 SE2d 242) (2012).
We begin with an overview of the statutory background and a discussion of the procedural history in these cases. The purpose of the Erosion and Sedimentation Act is set out as follows:
It is found that soil erosion and sediment deposition onto lands and into waters within the watersheds of this state are occurring as a result of widespread failure to apply proper soil erosion and sedimentation control practices in land clearing, soil movement, and construction activities and that such erosion and sediment deposition result in pollution of state waters and damage to domestic, agricultural, recreational, fish and wildlife, and other resource uses. It is therefore declared to be the policy of this state and the intent of this chapter to strengthen and extend the present erosion and sediment control activities and programs of this state and to provide for the establishment and implementation of a state-wide comprehensive soil erosion and sediment control program to conserve and protect the land, water, air, and other resources of this state.
OCGA § 12-7-2. The Erosion and Sedimentation Act provides that land-disturbing activities must conform with “best management practices.” OCGA § 12-7-6 (b). One of these practices is set forth in OCGA § 12-7-6 (b) (15), which states that “[t]here is established a 25[-]foot buffer along the banks of all state waters, as measured horizontally from the point where vegetation has been wrested by normal stream flow or wave action” unless one of six exceptions applies, including “[w]here the director determines to allow a variance that is at least as protective of natural resources and the environment.” No land-disturbing activities may be conducted within a buffer “except as otherwise provided by this paragraph.” OCGA § 12-7-6 (b) (15) (B). “State waters” include
any and all rivers, streams, creeks, branches, lakes, reservoirs, ponds, drainage systems, springs, wells, and other bodies of surface or subsurface water, natural or artificial, lying within or forming a part of the boundaries of the state, which are not entirely confined and retained completely [383]*383upon the property of a single individual, partnership, or corporation.
OCGA § 12-7-3 (16).
On May 28, 2010, the United States Army Corps of Engineers issued a permit to the County pursuant to Section 404 of the Federal Clean Water Act, authorizing construction of a 960-acre fishing lake. The permit allows the County to impound Tired Creek, a tributary of the Upper Ochlockonee River, by constructing a 3,000-foot long, 65-foot tall, and 450-foot wide dam. The construction of the dam and lake will destroy at least 129 acres of wetlands and over nine miles of streams.
The County also needed a buffer variance to proceed with its project. On April 30, 2012, the County submitted a revised application to the EPD for a buffer variance to permit the disturbance and loss of stream buffers at the site. In comments to the EPD, the River Groups maintained that the County’s application was deficient because it did not address impacts to buffers along wetlands on the site. The River Groups asserted that wetlands are “state waters” protected by buffers and that impacts to wetlands on the site would require a buffer variance and appropriate mitigation. On July 6, 2012, the Director granted the County’s application for a variance. The EPD’s Nonpoint Source Program Manager thereafter sent a letter to the River Groups in which he agreed that wetlands are state waters but asserted that “[w]etlands are features that usually do not require a buffer due to the lack of ‘wrested vegetation.’ Therefore, those impacts are not included in the buffer variance request.”
The River Groups then filed a petition for hearing in the Office of State Administrative Hearings against the Director seeking to invalidate the County’s buffer variance on the ground that it failed to account for and authorize impacts to wetlands. The County was permitted to intervene. The Director filed a motion to dismiss, later adopted by the County, asserting that the River Groups failed to identify an “order or action” they were challenging within the meaning of OCGA § 12-2-2 (c) (2) (A). The County filed a motion to dismiss, asserting that River Groups lacked standing under OCGA § 12-2-2 (c) (2) (A) because they were not aggrieved or adversely affected by the variance. The River Groups and the County filed cross-motions for summary determination. In his response to the River Groups’ motion for summary determination, the Director argued that the River Groups were not aggrieved or adversely affected by the variance.
The ALJ entered an order denying the motions to dismiss; granting the River Groups’ motion for summary determination; and reversing the buffer variance. The ALJ concluded that “applying the [384]*384plain and unambiguous meaning of the statute, a buffer is required for all state waters, including wetlands.” The Director filed a petition for judicial review in the Fulton Court, and the County filed a petition for judicial review in the Grady Court. The County was permitted to intervene in the Fulton Court, and the Director was permitted to submit briefs in the Grady Court.
The Fulton Court reversed the ALJ’s decision, concluding that the River Groups failed to challenge an “order or action” of the Director; the River Groups lacked standing; and the Director’s application of the Erosion and Sedimentation Act was consistent with its plain terms. The Grady Court subsequently entered an order reaching the same conclusions and reversing the ALJ’s decision, except that it found “no obvious error” in the ALJ’s conclusion as to standing. We granted the River Groups’ applications for discretionary appeal from the Superior Courts’ orders, and these appeals and cross-appeals followed.
2. Jurisdiction.
We first address the River Groups’ enumerations of error pertaining to the ALJ’s subject matter jurisdiction because if subject matter jurisdiction was lacking, neither the ALJ nor the Superior Courts were authorized to enter a judgment on the merits. See First Christ Holiness Church v. Owens Temple First Christ Holiness Church, 282 Ga. 883, 885 (655 SE2d 605) (2008).
(a) “Order or action.”
The River Groups contend that the Superior Courts erred in concluding that the ALJ lacked jurisdiction over their petition because the petition challenged the Director’s alleged failure to act, not an “order or action” of the Director. We conclude that the Superior Courts erred in reversing the ALJ on this issue.
The Erosion and Sedimentation Act provides that “[a] 11 hearings on and review of contested matters, orders, or permits issued by or filed against the director . . . shall be provided and conducted in accordance with subsection (c) of Code Section 12-2-2.” OCGA § 12-7-16. In turn, OCGA § 12-2-2 (c) (2) (A) provides in relevant part:
Any person who is aggrieved or adversely affected by any order or action of the director shall, upon petition to the director within 30 days after the issuance of such order or the taking of such action, have a right to a hearing before an administrative law judge. . . .
As the ALJ concluded, the River Groups’ petition challenged a specific action, the Director’s issuance of a variance. The petition asserts that the variance is invalid and in violation of the Erosion and [385]*385Sedimentation Act because the Director allowed the County to submit an application that failed to address alleged wetland buffers at the site and subsequently issued a variance failing to account for those buffers. At bottom, the River Groups are challenging the validity of the variance on the theory that both the application and the Director’s consideration of it were incomplete. The River Groups’ challenge to the variance is akin to the permit challenges in other environmental cases we have entertained that were likewise based in whole or in part on the regulating authority’s alleged incomplete consideration or regulation of a proposed project. See Longleaf Energy Assoc., LLC v. Friends of the Chattahoochee, 298 Ga. App. 753, 756-760 (2) (681 SE2d 203) (2009) (considering and rejecting claim that EPD permit for construction of coal-fired electric plant was invalid because it failed to limit carbon dioxide gas emissions); Coastal Marshlands Protection Committee v. Center for a Sustainable Coast, 286 Ga. App. 518, 521-529 (2) (649 SE2d 619) (2007), aff’d, Center for a Sustainable Coast v. Coastal Marshlands Protection Committee, 284 Ga. 736 (670 SE2d 429) (2008) (considering and rejecting petitioners’ claim that permit authorizing construction of marina and dock facilities over coastal marshlands was invalid because it failed to regulate permit-tee’s adjoining upland development).
The Superior Courts reasoned that the River Groups were challenging the Director’s inaction because the Director had no duty under the Erosion and Sedimentation Act to consider impacts to buffers at the site of the project if the application did not request permission to encroach on them or to require the County to address additional buffers in its application. The River Groups’ petition cited to and relied upon the regulation setting forth the buffer variance process, which, in fact, contemplates that a variance application will address all of the buffer impacts associated with a proposed project.1 Further, the County conceded before the ALJ that during the buffer variance application process, the Director required it to revise its application to increase the number of linear feet of streams and associated buffers that would be impacted by the project. While the parties may dispute whether the buffer provision in the Erosion and Sedimentation Act and the variance regulation apply to wetlands, [386]*386those issues relate to the merits of the River Groups’ petition. Meritorious or not, the petition invoked the ALJ’s jurisdiction to review the “orders or actions” of the Director.
(b) Standing.
The River Groups argue that the Fulton Court erred in concluding that the River Groups lacked standing because their members are notaggrievedoradverselyaffectedwithinthemeaningofOCGA § 12-2-2 (c) (2) (A). Conversely, the Director and the County argue that the Grady Court erred in failing to reverse the ALJ’s conclusion that the River Groups had standing.
OCGA § 12-2-2 (c) (3) (A) explains that
[p] ersons are “aggrieved or adversely affected,” [for purposes of OCGA § 12-2-2 (c) (2) (A)]... where the challenged action has caused or will cause them injury in fact and where the injury is to an interest within the zone of interests to be protected or regulated by the statutes that the director is empowered to administer and enforce.
We look to United States Supreme Court precedent concerning Article III standing for guidance in analyzing the River Groups’ standing under OCGA § 12-2-2 (c) (2) (A) and (c) (3) (A). See Center for a Sustainable Coast v. Turner, 324 Ga. App. 762, 764 (751 SE2d 555) (2013). The United States Supreme Court has explained that
to satisfy Article Ill’s standing requirements, a plaintiff must show (1) it has suffered an injury in fact that is (a) concrete and particularized and (b) actual or imminent, not conjectural or hypothetical; (2) the injury is fairly traceable to the challenged action of the defendant; and (3) it is likely, as opposed to merely speculative, that the injury will be redressed by a favorable decision. An association has standing to bring suit on behalf of its members when its members would otherwise have standing to sue in their own right, the interests at stake are germane to the organization’s purpose, and neither the claim asserted nor the relief requested requires the participation of individual members in the lawsuit.
(Citations and punctuation omitted.) Friends of the Earth v. Laidlaw Environmental Svcs. (TOC), 528 U. S. 167, 180-181 (II) (A) (120 SCt 693, 145 LE2d 610) (2000). “Environmental plaintiffs adequately allege injury in fact when they aver that they use the affected area and are persons for whom the aesthetic and recreational values of the area will be lessened by the challenged activity.” (Citation and punctuation omitted.) Turner, supra, 324 Ga. App. at 765. The issues [387]*387in dispute here are whether the River Groups can show that their members’ alleged injuries are fairly traceable to the buffer variance and redressable in this action.
In his response to the River Groups’ motion for summary determination, the Director requested that the ALJ make a determination on the issue of standing in accordance with OCGA § 12-2-2 (c) (3) (A), which states in part:
... In the event the director asserts in response to the petition before the administrative law judge that the petitioner is not aggrieved or adversely affected, the administrative law judge shall take evidence and hear arguments on this issue and thereafter make a ruling on this issue before continuing with the hearing. The burden of going forward with evidence on this issue shall rest with the petitioner.
The statute contemplates an evidentiary hearing on the issue of standing. See Smart Growth — Forsyth County v. Couch, Docket No. OSAH-BNR-ES-0707202-60-Howells, Order on Standing, March 2, 2007,2007 WL 828306, at *2 (ALJ conducted hearing on standing and heard testimony from petitioners’ witnesses).2 During oral argument on the parties’ motions, the Director’s counsel, rather than requesting that an evidentiary hearing take place, stated that because the Director had invoked OCGA § 12-2-2 (c) (3) (A), the River Groups were required to come forward with evidence to establish causation in support of their motion for summary determination. The Director’s counsel argued that the River Groups failed to do so. The River Groups, however, already had presented evidence relevant to standing, as they attached several affidavits to their petition, including affidavits from two individuals who are members of both organizations and live in close proximity to the proposed lake. Neither the Director nor the County disputed the veracity of these affidavits. Thus, the issue before the ALJ was whether those affidavits are legally sufficient to establish the individuals’ standing.3 We conclude that they are.
[388]*388One of the affiants stated that she has enjoyed walking along Tired Creek and its tributaries, has canoed on the Ochlockonee River downstream from the proposed lake, and hopes to continue these activities. She believes that as a result of the buffer variance, the waters downstream will be less desirable for viewing, recreation, and other uses. The other affiant stated that she enjoys walking along the waters downstream from the site and is afraid that the destruction of the buffers will negatively impact the water quality downstream. She is also concerned the variance will negatively impact migratory birds and destroy trails animals use when seeking food and water. The affiants stated that their use and enjoyment of waters on the site and downstream has been and will continue to be significantly and negatively affected by the variance.
To establish standing, the River Groups must show that the injuries described by the members are “fairly traceable to the challenged action of the defendant, and not the result of the independent action of some third party not before the court.” (Citation omitted.) Bennett v. Spear, 520 U. S. 154, 167 (III) (A) (117 SCt 1154, 137 LE2d 281) (1997). Here, it is undisputed that the buffers required by the Erosion and Sedimentation Act at the site could not be disturbed and the lake project could not go forward without both the Section 404 permit and the buffer variance. As such, even if the Section 404 permit is also a cause of the damage to and loss of alleged wetland buffers, the loss is nonetheless fairly traceable to the buffer variance. See Mattaponi Indian Tribe v. Commonwealth, Dept. of Environmental Quality, 261 Va. 366, 375-378 (541 SE2d 920) (2001) (petitioners had standing to challenge state permit authorizing reservoir for public water supply although project also would require federal Section 404 permit; state permit protected separate interests and could cause injury). In concluding that the River Groups failed to establish that the buffer variance, rather than the Section 404 permit, caused their members’ injuries, the Fulton Court relied on OCGA § 12-7-6 (b) (15) (C) (i), which requires that the Board of Natural Resources adopt rules with specific criteria for the grant or denial of a variance and states that the
rules shall provide, at a minimum, that the director shall consider granting a variance in the following circumstances: (i) Where a proposed land-disturbing activity within the buffer would require the landowner to acquire a [Section 404] permit,.. . and the Corps of Engineers has approved a mitigation plan to be implemented as a condition of such a permit.
[389]*389The applicable regulation allows a variance in this circumstance. Ga. Comp. R. & Regs. r. 391-3-7-.05 (2) (h). While the statute and regulation establish that a variance may be available when a Section 404 permit has been issued and is subject to a mitigation plan, a variance is not a foregone conclusion. Rather, a detailed application is still required, and the Director must consider various factors in deciding whether to grant it. See Ga. Comp. R. & Regs. r. 391-3-7-.05 (3)-(5).
We also disagree with the Fulton Court’s conclusion that the permanent loss of wetland buffers due to flooding would be inconsequential since the wetlands they protect will be destroyed by flooding. It is undisputed that the County was required to apply for a buffer variance in connection with the inundation and permanent loss of streams and their buffers at the lake site. That the County was required to do so is evidence that permanent buffer loss in connection with a project like the County’s implicates the interests protected by the Erosion and Sedimentation Act.
Finally, we reject the County’s argument that the River Groups cannot establish redressability. The County’s reliance on our decision in Turner, supra, is unavailing. In that case, an environmental group challenged a consent order the Director entered into with a property owner after discovering that the property owner had constructed a bulkhead in a salt water marsh area without first requesting a buffer variance. 324 Ga. App. at 762-763. We held that the environmental group could not establish that the relief requested would redress its injuries. Id. at 768. We reasoned that if the ALJ issued an order invalidating the consent order, the bulkhead would remain in place. Id. We also concluded that the ALJ could not require the Director to order removal of the bulkhead because such a requirement would amount to improper interference with an agency’s exercise of its discretionary enforcement authority. Id. The relief requested here, reversal or invalidation of the variance, does not implicate the Director’s enforcement authority. Further, an ALJ possesses authority to reverse the Director’s decision on a variance application if the decision does not comport with the requirements of the Erosion and Sedimentation Act and the variance regulation. See The Sembler Company v. Environmental Protection Div., Dept. of Natural Resources, Docket No. OSAH-DNR-ES-02-04135-60-SEP, Final Decision, March 18, 2002, 2002 WL 34125519 (reversing denial of buffer variance application).
For these reasons, we reject the Director’s and County’s arguments that the Grady Court erred by failing to reject the ALJ’s determination that the River Groups had standing.
[390]*3903. Buffer requirement.
Finally, the River Groups contend that the Superior Courts erred in concluding that under the plain statutory language, buffers exist only along the banks of state waters4 where vegetation has been wrested by normal stream flow or wave action. We agree.
As this case involves a matter of statutory construction, we must “look diligently for the intention of the General Assembly and . . . follow the literal language of the statute unless it produces contradiction, absurdity, or such an inconvenience as to insure that the legislature meant something else.” Judicial Council of Ga. v. Brown & Gallo, 288 Ga. 294, 296-297 (702 SE2d 894) (2010) (citation and punctuation omitted). See also OCGA § 1-3-1 (a). With these principles in mind, we conclude that the Superior Courts erred by determining that the 25-foot buffer requirement of the Erosion and Sedimentation Act does not apply unless the state waters at issue have banks with wrested vegetation.
As detailed above, OCGA § 12-7-6 (b) (15) (A)5 establishes “a 25[-]foot buffer along the banks of all state waters.” “State waters” is [391]*391a defined term, and the definition is broad. “State waters” includes
any and all rivers, streams, creeks, branches, lakes, reservoirs, ponds, drainage systems, springs, wells, and other bodies of surface or subsurface water, natural or artificial, lying within or forming a part of the boundaries of the state, which are not entirely confined and retained completely upon the property of a single individual, partnership, or corporation.
OCGA § 12-7-3 (16). That broad definition of “state waters” is narrowed, for purposes of the applicability of the 25-foot buffer requirement in OCGA § 12-7-6 (b) (15) (A), by six statutory exceptions not applicable here; the requirement otherwise applies to “all state waters.” One of these exceptions is for a category of waters to which the General Assembly deemed a buffer inappropriate (ephemeral streams). OCGA § 12-7-6 (b) (15) (A) (v). Two others give the Director limited discretion to grant variances. OCGA § 12-7-6 (b) (15) (A) (ii), (iii). In a subordinate clause, the statute goes on to direct that the buffer is to be “measured horizontally from the point where vegetation has been wrested by normal stream flow or wave action.” The question before us is whether that direction entails a seventh exception.
We hold that it does not. It merely specifies the location of the buffer — alongside the “bank” or the “margin of the watercourse,” Webster’s New International Dictionary (1954) — and a method for measuring it. To treat that language as a seventh exception, as the Superior Courts did, would be to hold that no buffer is required along the banks of streams, rivers, and lakes that have rocky or sandy shores where lines of wrested vegetation cannot be found. This interpretation would hold that buffer protection is afforded in fits and starts, should the line of wrested vegetation not be continuous, an absurdity not intended by the legislature. See Judicial Council of Ga., supra, 288 Ga. at 296-297.
The wrested vegetation measurement language was added to the statute in 1994. Formerly, the statute had provided that the buffer was “measured from the stream banks.” In 1994, the General Assembly amended that language to provide that the buffer was measured “from the point where vegetation has been wrested.” The 1994 version of the statute listed three exceptions to the buffer requirement. Had the General Assembly intended to except state waters without wrested vegetation from the buffer requirement, it would have said so expressly in the list of exceptions, not by implication in a subordinate clause that addresses measurements.
[392]*392The statute is internally inconsistent. As the dissent says, it does not set out an alternative to its provision that buffers are to be measured from wrested vegetation. On the other hand it sets out explicitly the six exceptions to the rule establishing a buffer along the banks of all state waters — each narrower than the purported exception for state waters without wrested vegetation. It is our duty to resolve that inconsistency so as to give effect to the intent of the General Assembly and to avoid absurd results.
Here the General Assembly stated its intent: “to strengthen and extend the present erosion and sediment control activities and programs of this state” and “[to] protect the land, water, air, and other resources of this state.” OCGA § 12-7-2. See also MarkMcCarty et al., Peach Sheets: Conservation and Natural Resources, 12 Ga. St. U. L. Rev. 39, 47 (1995) (reporting on another change made to the Erosion and Sedimentation Act the year after the “wrested vegetation” language was adopted: “The Senate committee substitute made a blanket change of terms from ‘streams’ to ‘waters,’ and this change was ultimately adopted in the Act. Environmental lobbyists and the EPD encouraged this change to broaden the scope of regulation to waters that do not flow, such as lakes and marshlands.”) (footnotes omitted). The Superior Courts erred in construing the statute in a manner contrary to the General Assembly’s stated intent.
Judgments reversed.
