Plaintiffs-Appellees, National Resources Defense Council (NRDC) and Waterkeep *1238 er Alliance Inc. (collectively, NRDC), sued Defendants-Appellants, the United States Environmental Protection Agency and its administrator (collectively, EPA), under the Clean Water Act (CWA) and the Administrative Procedure Act (APA), seeking to compel the EPA to promulgate effluent limitation guidelines (ELGs) and new source performance standards (NSPSs) for storm water pollution discharges caused by the construction and development industry (construction industry). The States of Connecticut and New York, and the New York State Department of Environmental Conservation (collectively, state-in-tervenors) intervened on behalf of NRDC; the National Association of Home Builders and Associated General Contractors of America (collectively, industry-intervenors) intervened on behalf of the EPA.
The district court exercised its jurisdiction under the Clean Water Act’s citizen-suit provision, CWA § 505(a)(2), 33 U.S.C. § 1365(a)(2), 1 denied Defendants’ motion to dismiss, granted Plaintiffs partial summary judgment on their claim that the CWA requires the EPA to issue ELGs and NSPSs for the construction industry, and issued a permanent injunction compelling the EPA to do so. 2 We have jurisdiction to review these decisions under 28 U.S.C. §§ 1291 and 1292(a), and we affirm.
BACKGROUND
A. Statutory Background
Congress enacted the CWA “to restore and maintain the chemical, physical, and biological integrity of the Nation’s waters.” 33 U.S.C. § 1251(a). In furtherance of the CWA’s objective of eliminating the “discharge of pollutants into the navigable waters,” id., the Act prohibits the “discharge of any pollutant.” CWA § 301(a), 33 U.S.C. § 1311(a). The CWA defines the “discharge of a pollutant” as “any addition of any pollutant to navigable waters from any point source.” CWA § 502(12), 33 U.S.C. § 1362(12). A “point source” is “any discernable, confined and discrete conveyance, including but not limited to[,] any pipe, ditch, channel ... from which pollutants are or may be discharged.” CWA § 502(14).
Despite § 301(a)’s general prohibition on the discharge of pollutants, the CWA also establishes a permit system that authorizes the discharge of some pollutants — the National Pollutant Discharge Elimination System (NPDES).
See
CWA § 402, 33 U.S.C. § 1342. Under the NPDES, the EPA and approved states may issue permits for the discharge of pollutants that meet certain requirements outlined in § 402. Taken together, §§ 301(a) and 402 “ ‘prohibit[ ] the discharge of any pollutant from a point source into navigable waters of the United States without an NPDES permit.’ ”

NPDES permits “place limits on the type and quantity of pollutants that can be released into the Nation’s waters,”

*1239
Indians,
The specific effluent limitations in an NPDES permit are determined according to the more general ELGs and NSPSs, guidelines that are separately promulgated by the EPA. CWA § 304(b), 33 U.S.C. § 1314(b); CWA § 306(b), 33 U.S.C. § 1316(b);
E.I. duPont de Nemours & Co. v. Train,
Section 304(m) provides that, every two years, the EPA “shall publish in the Federal Register a plan which shall ... identify categories of sources discharging toxic or nonconventional pollutants” for which ELGs and NSPSs have not yet been published, and “establish a schedule for promulgation of effluent guidelines for categories identified.” Under this schedule, the “promulgation of [these] guidelines shall be no later than ... 3 years after the publication of the plan.” Id. ELGs and NSPSs are relevant to this appeal because the Plaintiffs claim that the EPA violated a non-discretionary duty to promulgate ELGs and NSPSs for the construction industry after it was listed as a point-source category in a plan developed under § 304(m).
B. Administrative Proceedings
In March 1999, the EPA announced that it was undertaking rulemaking to address pollution from storm water discharge associated with construction activities, “specifically for new development, as well as to those associated with redevelopment activities.” 64 Fed.Reg. 15,158, 15,158 (March 30, 1999). In its public notice, the EPA stated that it “chose to begin development of [ELGs] for the construction and development industry[, in relevant part,] to support applicable state and local requirements for erosion and sediment controls and storm water best management practices,” because “[s]tate and local requirements vary widely [and][s]ediment loadings from construction site discharges can be orders of magnitude higher than those associated with discharges from undisturbed areas,” and also because “construction site runoff can contribute high loadings of nutrients and metals to receiving streams.” Id. In 2000, the EPA published its final notice of an effluent guidelines plan, which listed construction activities as a point-source category requiring guidelines under § 304(m). 65 Fed.Reg. 53,008, 53,011 (Aug. 31, 2000).
*1240 On June 24, 2002, the EPA issued a proposed rule to address storm water discharge from construction sites. 67 Fed. Reg. 42,644, 42,644 (June 24, 2002). The EPA did not set forth a single proposed rule, but described three “options” it was considering. “Option 1” was to establish “minimum requirements for conducting site inspections and providing certification as to design and completion of controls required by” the authority issuing NPDES permits. Id. at 42,646. “Option 2” would establish ELGs as well as the minimum requirements comprising Option 1. Id. “Option 3” would establish “no new requirements,” and “[b]oth the control requirements and the certification requirements would be left to the best professional judgment of the permitting authority.” Id.
On April 26, 2004, the EPA published its final action under the caption “Proposed Rule: Withdrawal.” 69 Fed.Reg. 22,472, 22,472 (April 26, 2004). The EPA stated: “[t]his action withdraws the proposed [ELGs and NSPSs] that EPA proposed for the construction and development industry” on June 24, 2002. Id. at 22,473. It further stated, “[w]e have decided not to promulgate [ELGs] and standards for the construction and development industry and instead have selected the option [Option 3] that relies on the range of existing programs, regulations, and initiatives at the Federal, State, and local level for the control of storm water runoff from construction sites.” Id. at 22,477.
The EPA explained its decision “not to promulgate[ELGs] and standards” by stating that it believed that construction site storm water discharges were already “being adequately addressed” because the “existing NPDES” regulations require permits for the vast majority of construction sites nationwide, and that the cost was “simply too high and ... disproportionately large” given the reductions that would be attributable to the proposed ELGs. Id. The EPA had determined that the annual cost of the proposed ELGs would be more than half a billion dollars and would result in the displacement of a number of jobs while the existing permit programs were capable of controlling 80-90% of sediment runoff from construction sites and the proposed rule would only remove an additional 1% more. Id. The EPA also “decided not to promulgate NSPS[s] because ... discharges associated with construction activity generally are not appropriately characterized as ‘new sources,’ ” and the EPA believed that the definition of “new source” should be read to exclude construction sites. Id. at 22,480 (“To include construction activity itself within the definition of a ‘new source’ would be to view construction sites as things that are themselves constructed.”).
In subsequent years, the EPA removed the construction industry from plans it published under § 304(m). See 69 Fed. Reg. 53,705 (Sept. 2, 2004); 71 Fed.Reg. 76,644 (Dec. 21, 2006). In its 2004 plan, the EPA stated:
[T]he analysis under CWA section 304(m)(l)(B) applies only to industrial categories of sources that are discharging non-trivial amounts of toxic or non-conventional pollutants to waters of the United States. EPA did not consider, under this analysis, industrial activities where conventional pollutants, rather than toxic or non-conventional pollutants, are the pollutants of concern. For example, although EPA had identified stormwater discharges from [the construction industry] as a new category in its 2000 and 2002 effluent guidelines *1241 program plans, EPA is not identifying [the construction industry] in this 2004 plan based on new information that discharges from this activity consist predominately of conventional pollutants under CWA § 304(a)(4), in this case total suspended solids.
69 Fed.Reg. at 53,718. In its 2006 plan, EPA similarly stated that it “did not identify ... the construction industry because its discharges consist almost entirely of conventional pollutants,” and that the “EPA mistakenly identified this industry under section 304(m)(1)(B) in the 2002 plan, not realizing that its discharge” was so composed. 71 Fed.Reg. at 76,664-65. According to the EPA, it corrected its mistake by removing the industry from its 2004 plan. Id.
C. District Court Proceedings
NRDC and the state-intervenors brought this suit to challenge the EPA’s decision not to issue ELGs and NSPSs for the construction industry after it had listed the industry in a plan it issued under § 304(m). The EPA and the industry-intervenors moved to dismiss, claiming that this court, not the district court, had original jurisdiction pursuant to § 509(b)(1)(E), 33 U.S.C. § 1369(b)(1)(E), that the Plaintiffs lacked standing to sue, and that certain claims were precluded. 3 The district court denied the motion to dismiss.
The district court granted the Plaintiffs’ motion for partial summary judgment on the basis that the EPA failed to comply with the CWA by not performing its non-discretionary duty to promulgate ELGs and NSPSs for the construction industry. The district court issued a permanent injunction requiring the EPA to issue ELGs and NSPSs for the construction industry no later than December 1, 2009. Defendants now appeal these rulings.
DISCUSSION
A. District Court’s Original Jurisdiction
1. Standard of Review
We review a district court’s assumption of jurisdiction de novo.
United States v. Bennett,
2. Analysis
CWA § 505(a)(2) grants the district court jurisdiction over suits “against the Administrator where there is alleged a failure of the Administrator to perform any act or duty under this chapter which is not discretionary with the Administrator.” Section 505(a)(2) is an exclusive grant of original jurisdiction to the district courts.
Trustees for Alaska v. EPA
Defendants argue that the district court erred in exercising jurisdiction under § 505(a)(2), and that this court has exclusive original jurisdiction over Plaintiffs’ claim that the EPA violated its non-discretionary duty to promulgate ELGs and NSPSs under § 509(b)(1)(E). 4 Plaintiffs argue that the district court properly exercised its jurisdiction. We agree with Plaintiffs, and we hold that where a plaintiff alleges that the EPA has failed to perform a non-discretionary duty under the CWA and the plaintiff does not challenge the substance of any existing regulations, the district courts have exclusive jurisdiction under § 505(a)(2).
In
Trustees for Alaska,
the NRDC alleged a failure by the EPA “to comply with a nondiscretionary duty to promulgate industry-wide rules.”
We acknowledge that the underlying facts in Trustees for Alaska differ slightly from the facts of this case. Though the EPA did not promulgate ELGs for the relevant industry in either case, in Trustees for Alaska, the agency had not undertaken a rulemaking or any other procedural step towards promulgating ELGs. In contrast, here, the EPA gave notice and provided comment periods and proposed three “options” before choosing not to promulgate ELGs and NSPSs related to storm water runoff from construction sites. And, as a result of its rulemaking, the EPA made an affirmative choice to “rel[y] on the range of existing programs, regulations, and initiatives at the Federal, State, and local level for the control of storm water runoff from construction sites.” 69 Fed.Reg. at 22,477.
This distinction does not affect our jurisdictional analysis, however, because Plaintiffs do not challenge the substance of any of these existing programs or regulations. Plaintiffs do not discuss the substance of any existing regulations or express any opinion concerning the existing regulations. Thus, just like the plaintiffs in
Trustees for Alaska,
Plaintiffs here are concerned exclusively with the EPA’s
failure
to promulgate certain guidelines. Such an action falls squarely within the district court’s jurisdiction.
Trustees for Alaska,
Indeed, the fact that Plaintiffs do not challenge the substance of any existing regulations is precisely why § 509(b)(1)(E) is inapplicable. Section 509(b)(1)(E) grants the court of appeals jurisdiction to “[rjeview ... the Administrator’s action ... in approving or promulgating any effluent limitation or other limitation under section 1311, 1312, 1316, or 1345 of this title.” Even if, as Defendants argue, we could construe the EPA’s decision to rely on existing regulations as an “approval” of an “other limitation” under one of the enumerated sections, this is insufficient to bring Plaintiffs’ claim within § 509(b)(1)(E). This is so because Plaintiffs do not seek a review of the existing regulations that the Administrator is alleged to have “approved.”
To the extent any doubt remains about whether the district court had original jurisdiction over Plaintiffs’ claim, it is easily resolved by our recent decision in
Our Children’s Earth Foundation.
In
OCEF,
environmental groups contended that the EPA “failed to fulfill its mandate to review effluent guidelines and limitations in a timely manner and in accord with technology-based standards.”
This case differs from the Tenth’s Circuit’s decision in
Maier
precisely because Plaintiffs are not requesting a review of existing regulations. In
Maier,
the court held that it had jurisdiction under § 509(b)(1)(E) to hear a challenge to the EPA’s denial of a petition requesting that the EPA initiate a rulemaking on certain CWA regulations.
Pennsylvania Department of Environmental Resources v. EPA
Significantly, the Third Circuit noted that in cases where the courts of appeal have jurisdiction to review a failure to act under § 509, the review focuses on the substance or effect of promulgated regulations and not “a petitioner’s request that the EPA be ordered to promulgate new or different regulations.” Id. at 996. We agree with the Third Circuit that “an allegation of inadequacy of a set of regulations is quite different from” what Plaintiffs’ allege here — “that a needed regulation was nonexistent.” Id. We therefore hold that the district court properly exercised its jurisdiction over Plaintiffs’ claim that the EPA had violated its non-discretionary duty to promulgate ELGs and NSPSs for the construction industry under § 505(a)(2).
B. Standing
1. Standard of Review
We review a district court’s determination of standing de novo.
Buono v. Norton,
2. Analysis
a. Environmental-Group Plaintiffs
Organizations have standing to sue on behalf of their members when: “(a) [the] members would otherwise have standing to sue in their own right; (b) the interests [the organization] seeks to protect are germane to the organization’s purposes; and (c) neither the claim asserted nor the relief requested requires the participation of individual members in the lawsuit.”
Ecological Rights Found, v. Pac. Lumber Co.,
To meet Article Ill’s standing requirements, the party invoking federal jurisdiction bears the burden to show that it has: (1) “suffered an injury in fact — an invasion of a legally protected interest which is (a) concrete and particularized ... and (b) actual or imminent, not conjectural or hypothetical”; (2) that the injury is “fairly trace[able] to the challenged action of the defendant”; and (3) that it is “likely, as opposed to merely speculative, that the injury will be redressed by a favorable decision.”
Lujan v. Defenders of Wildlife,
We turn first to whether the members of the environmental-group Plaintiffs have suffered an injury in fact. “The ‘injury in fact’ requirement in environmental cases is satisfied if an individual adequately shows that she has an aesthetic or recreational interest in a particular place, or animal, or plant species and that that interest is impaired by a defendant’s conduct.”
Id.; see also Ocean Advocates v. U.S. Army Corps of Eng’rs,
Members of the NRDC and Water-keeper Alliance have submitted several declarations averring that they have suffered an injury in fact. These declarations state that the members have, for years, used particular waterways for aesthetic and recreational purposes. They also state that the individuals’ use and enjoyment of those waterways has been diminished due to storm water discharge from construction sites, and many declarations describe having observed storm water discharge flowing directly from construction sites into the waterways the members use. The Supreme Court found similar evidence sufficient to establish injury in fact in
Friends of the Earth.
In that case, the Court concluded that the environmental group members established injury in fact where their “reasonable concerns about the effects of [Laidlaw’s discharges], directly affected [their] recreational, aesthetic, and economic interests.”
Friends of the Earth,
Industry-intervenors also argue that the members of the environmental-group Plaintiffs cannot show that their injury is “fairly trace[able] to the challenged action of the defendant” or “redressable” by the relief they request — i.e., the EPA’s promulgation of ELGs and NSPSs.
Lujan,
At the outset of this analysis, we observe that Plaintiffs’ showing on these two factors — whether their injuries are “traceable” to the EPA’s failure to promulgate
*1246
ELGs and NSPSs and would be “redressed” by the EPA’s promulgation of ELGs and NSPSs — cannot be entirely precise absent knowledge of the substance of the regulations that the EPA would promulgate if required to do so.
6
As the district court noted, to require a precise showing “would mean that
no
plaintiff would have standing to bring such a suit, as one cannot demonstrate the efficacy of regulations that have yet to be issued.” Thus, Plaintiffs can satisfy the “traceability” and “redressability” factors by showing that the type of storm water discharge causing their injury is that which ELGs and NSPSs aim to address, and that ELGs and NSPSs are likely to reduce the risk of the pollution causing their injury.
See Ecological Rights Found.,
First, the members’ declarations support that the pollution they complain of is that which ELGs and NSPSs aim to address. The members’ declarations support that storm water discharge flows from active construction sites into the bodies of water they use and enjoy, and that the storm water runoff they complain of is polluting and diminishing the quality of the bodies of water they use. See, e.g., Anna E. Slawsky Deck ¶ 8 (“I have personally seen sediment run off from a 2-acre construction site and a 33-aere construction site (Puppy Creek runs brown from this site) in Lowell during rains and the erosion along Route 74 mentioned above.”); Michael Mullen Deck ¶ 17 (“[Beginning in 2000 until the present day, I have conducted inspections of the Prospect Ridge Subdivision Extension in Troy, Alabama.... A number of my inspections at Prospect Ridge were made during or just following rain events. During my inspections I witnessed runoff with very high turbidity and excessive amounts of sediment entering streets and subsequently storm drains or unnamed tributaries to Big Creek.”); Don McEnhill Deck ¶ 15 (“I have personally witnessed construction activities causing major discharges of pollutants, including sediment, and documented well over two-dozen construction sites releasing pollutants into the Russian River watershed.”); id. ¶ 24 (“During the rain season of 2003-2004, I conducted several site visits at the Vintage Greens subdivision development in Windsor, California. I was interested in [this] development because it was a large *1247 development and stormwater discharged ... would flow into the Windsor Creek and then to the Russian River. During my visits I witnessed constant stormwater flows containing sediment from the construction site ... brown in color and very turbid.”); Constance Powell Deck ¶¶ 6-7 (“Construction and development is continuing ... I have personally seen sediment run off from construction sites flow directly to Lake Johnson.”). In one declaration, Michael Mullen, the Choctawhat-chee Riverkeeper and the Director of the Center for Environmental Research and Service at Troy University, described how he sampled the turbidity of two tributaries and concluded that, as a result of construction runoff, the turbidity downstream from the construction site was higher than the turbidity upstream in both tributaries. Michael Mullen Deck ¶ 23.
Industry-intervenors contend that the environmental-group Plaintiffs’ causation evidence is nevertheless insufficient because they have not definitively established that the pollution they complain of is composed of the toxic and non-conventional pollutants that ELGs and NSPSs address. We disagree. By including the construction industry in plans issued pursuant to § 304(m), the EPA necessarily identified the construction industry as a source of toxic and nonconventional pollutants. See CWA § 304(m)(l)(B) (requiring the EPA to publish a plan identifying “categories of sources discharging toxic or nonconventional pollutants for which guidelines ... have not previously been published”) (emphasis added). In fact, the EPA has explicitly stated that storm water runoff from construction sites includes toxic and nonconventional pollutants. 7
American Petroleum Institute v. EPA,
Second, by requiring effluent limitations, which are developed according to ELGs and NSPSs, as a part of a strategy to eliminate the discharge of pollutants and restore and maintain the integrity of the Nation’s waters, 33 U.S.C. § 1251(a), Congress has expressed its view that developing ELGs and NSPSs reduces the risk of the pollution causing the members’ injury. Where Congress has expressed the need for specific regulations relating to the environment, that expression supports an inference that there is a causal connection between the lack of those regulations and adverse environmental effects.
See Nat’l Wildlife Fed’n,
Together, the members’ declarations establishing that storm water discharge from the construction industry is polluting the waterways they use, the EPA’s findings that such discharge may consist of toxic and non-conventional pollutants, and Congress’ determination that ELGs and NSPSs reduce the risk of such pollution, are sufficient to establish “traceability” and “redressability.” Based on the foregoing, we conclude that the environmental-group Plaintiffs have standing.
b. State-intervenors
Only one of the Plaintiffs must have standing to permit our review. Thus, we consider the state-intervenors’ standing, a matter that industry-intervenors challenge, only very briefly.
See Massachusetts v. EPA
State-intervenors claim an injury to their proprietary interest in protecting their waterways.
8
See City of Sausalito v.
*1249
O’Neill,
The state-intervenors have also submitted declarations to establish that the pollution they complain of is connected to a lack of national standards. Patricia Primi, an Environmental Scientist in the Environmental Protection Bureau of the New York State Office of the Attorney General, submitted a declaration attesting that storm water runoff from construction sites in Vermont, New Hampshire, and Massachusetts is contributing pollutants to the Long Island Sound, and that storm water runoff from Vermont is contributing pollutants to the Lake Champlain Basin. Patricia Primi Decl. ¶¶ 18-19, 23-24. Angus Eaton, the Chief of the General Permits Section in the Division of Water for the New York State Department of Environmental Conservation, submitted a declaration supporting that the upstream states to which Primi referred have different discharge standards enabling a discharge downstream of excessive amounts of “pollutants found in stormwater runoff’ from construction sites. Angus K. Eaton Decl. ¶ 16. And, as stated above, we take into account Congress’ view that the promulgation of ELGs and NSPSs will reduce the likelihood of the pollution of which the state-intervenors complain. See supra Section B.2.a. We therefore conclude that the state-intervenors also have standing.
C. The EPA’s Duty to Promulgate ELGs and NSPSs
1. Standard of Review
We review a district court’s grant of summary judgment de novo.
Buono,
2. Analysis
We must decide whether the EPA had discretion to determine whether to promul *1250 gate ELGs and NSPSs for storm water runoff from the construction industry once it listed the construction industry as a point source category in a plan published pursuant to § 304(m). We hold that once the EPA listed the construction industry as a point-source category, it was required to promulgate ELGs and NSPSs. We therefore affirm the district court’s grant of summary judgment and the permanent injunction.
When reviewing the EPA’s construction of a statute that it administers, we follow the two-step approach set forth in
Chevron U.S.A. v. Natural Res. Def. Council,
We conclude that the language of the CWA, when viewed in its entirety, is clear that the EPA must promulgate ELGs and NSPSs for the point-source categories it lists in any plan it publishes under § 304(m). Our analysis begins with § 304(m)(l), which requires the EPA, every two years after February 4, 1987, to “publish in the Federal Register a plan that shall”
(A) establish a schedule for the annual review and revision of promulgated effluent guidelines ...; (B) identify categories of sources discharging toxic or nonconventional pollutants for which guidelines under subsection (b)(2) ... and section 1316 ... have not previously been published; and (C) establish a schedule for promulgation of effluent guidelines for categories identified in subparagraph (B), under which promulgation of such guidelines shall be no later than ... 3 years after the publication of the plan for categories identified in later published plans [i.e. plans not published within 12 months after February 4,1987].
By requiring the EPA to “establish a schedule” under which the guidelines — the ELGs and NSPSs — are promulgated “no later than ... 3 years after the publication of the plan,” Congress’ intent to require the EPA to promulgate guidelines is clear.
9
Indeed, Congress used unequivocal language, stating, in relevant part: “[the]
*1251
promulgation of such guidelines
shall be no later than
... 3 years after the publication of the plan.” CWA § 304(m) (emphasis added.);
see Alabama v. Bozeman,
Other provisions in the CWA likewise support that Congress intended the promulgation of ELGs and NSPSs to be mandatory once a point-source category was listed in a plan under § 304(m).
See Nat’l Ass’n of Home Builders v. Defenders of Wildlife,
— U.S. -,
Section 402(a)(1) also supports our interpretation. That section governs the NPDES and states the EPA may issue NPDES permits if the discharge will meet: (A) “all applicable requirements under [various other sections] of this title,” including the section governing effluent limitations, which are designed according to ELGs and NSPSs; or (B) if “prior to the taking of necessary implementing actions relating to all such requirements, such conditions as the Administrator determines necessary to carry out the provisions of this chapter.” CWA § 402(a)(1). Subsection (B) is explicit that it applies only “prior to the taking of necessary implementing actions” relating to the requirements in subsection (A). (Emphasis added). Thus, § 402(a)(1)(B) sets forth a system for assessing NPDES permits only until the EPA promulgates the requirements referenced in § 402(a)(1)(A) and does not contemplate that the EPA might never promulgate the requirements referenced in § 402(a)(1)(A). Rather, § 402(a)(1) supports that Congress assumed that “requirements,” including effluent limitations, which are guided by ELGs and NSPSs, would be in place after an interim period.
While we conclude that the CWA is unambiguous that the EPA must promulgate ELGs and NSPSs for point-source categories listed in a plan pursuant to § 304(m), were we to find the statute ambiguous and consider whether the EPA’s interpretation was based on a “permissible construction,” we would reach the same conclusion.
The addition of § 304(m) to the CWA stemmed from Congress’ frustration with “the slow pace in which these regulations [were] promulgated.” S.Rep. No. 99-50, at 3 (1985) (“Although the EPA continues to move forward with developing guidelines for the installation of cleanup technology for ... dischargers, the slow pace in which these regulations are promulgated continues to be frustrating. Of the 29 industrial categories established in 1977 for which guidelines were required to be *1252 promulgated 5 still remain to be completed.”)- Congress’s desire to speed up the promulgation of ELGs and NSPSs would be completely frustrated if § 304 were viewed merely as a planning mechanism and did not require the actual promulgation of ELGs and NSPSs. The Senate Report quoted confirms that Congress did not view § 304 as a planning mechanism. It states that “[g]uidelines are required for any category of sources discharging significant amounts of toxic pollutants. In this use, ‘significant amounts’ does not require the [EPA] to make any determination of environmental harm; any non-trivial discharges from sources in a category must lead to effluent guidelines.” Id. at 24-25 (emphasis added).
Our recent opinion in
OCEF
does not contradict our interpretation. In
OCEF,
we held that the EPA’s decisions on “whether to revise the effluent guidelines and whether to incorporate technology-based criteria in its periodic review of the guidelines” were discretionary duties.
Despite our conclusion that the EPA had a non-discretionary duty to promulgate ELGs and NSPSs in this case, we also must consider whether the EPA properly avoided this duty when it removed the construction industry from its plans published pursuant to § 304(m). Nothing in the CWA expressly
grants
the EPA the authority to remove a point-source category from a § 304(m) plan.
Cf.
42 U.S.C. § 7412(c)(9) (Clean Air Act provision expressly granting the EPA the authority to delist source categories). Moreover, we do not find the EPA’s view, that it is allowed under the statute to unilaterally delist a point-source category already identified in a § 304(m) plan with no process, to be a permissible construction of the statute.
See Chevron,
First, § 304(m)(1)(c) is clear that once a category is identified under subsection B, *1253 the promulgation of guidelines “shall be no later than ... 3 years after the publication of the plan.” This timeline effectuates Congress’ stated desire to force the EPA to more rapidly promulgate ELGs and NSPSs. If the EPA had the authority to delist point-source categories at its whim, however, this deadline would be rendered meaningless as the EPA could delist any point-source category to avoid the deadline set forth in § 304(m)(l)(c).
Second, § 304(m)(2) provides that “[t]he Administrator shall provide for public review and comment on the plan prior to final publication.” Thus, Congress determined that by the time a point-source category is listed in a § 304(m) plan, the EPA must have already engaged in a review process to consider whether the category should be listed. It follows logically that the three-year delay provided for in § 304(m)(1)(e) is not to decide whether to list a point-source category, but to allow the EPA to consider what the substance of the ELGs and NSPSs should be.
CONCLUSION
For these reasons, we AFFIRM the district court.

EPA,
. As used throughout this opinion, the term "Defendants” refers to the EPA and industry-intervenors. The term "Plaintiffs” refers to NRDC and state-intervenors.
. The Defendants have abandoned their claim preclusion argument on appeal.
. For analytical purposes in determining whether the district court or the court of appeals has original jurisdiction, we assume, as Plaintiffs claim, that the EPA’s duty to promulgate ELGs and NSPSs is not discretionary. We reach the merits of whether the EPA’s duty is discretionary in Section C, infra.
. The EPA has not argued that any Plaintiff lacks standing on appeal.
. Though Plaintiffs do not claim that the EPA denied them any procedure to which they were entitled, their suit is nevertheless similar to suits where the plaintiff claims such a procedural injury. The Supreme Court has noted that suits to force an agency to engage in a procedure do not require the same certainty that the result of that procedure will have the desired effect.
See Massachusetts v. EPA,
. For example, the EPA stated in 1999 that storm water runoff "may contain or mobilize high levels of contaminants,” including "toxic pollutants [and] toxins,” and that the highest concentrations of such contaminants occurs "during the first major storm after an extended dry period.” 64 Fed.Reg. 68,722, 68,724 (Dec. 8, 1999). The EPA went on to state “[(Individually and combined, these pollutants impair water quality, threatening designated beneficial uses and causing habitat alteration or destruction.” Id. The EPA further concluded that intensive construction activity may severely impact watersheds "because of high pollutant loads, primarily sediments.” Id. at 68,728. Though the EPA later suggested that discharge from the construction industry was "predominately” or "almost entirely” composed of conventional pollutants and that the EPA lacked data to indicate that toxic and non-conventional pollutants are found in construction site runoff nationwide, these statements do not squarely reject the EPA’s earlier statements and still allow that the discharge at issue is composed of at least some toxic or non-conventional pollutants or toxins. See 69 Fed.Reg. at 53,718 (Sept. 2, 2004); 71 Fed.Reg. at 76,664 (Dec. 21, 2006); 69 Fed.Reg. 22,472, 22,480 (April 26, 2004).

Massachusetts v. EPA,
the Supreme Court recognized that Massachusetts (among other states) was entitled to challenge the EPA’s rejection of its rulemaking petition regarding motor-vehicle emissions under the CWA.
. Defendants contend that our analysis of whether the EPA has a non-discretionary duty to promulgate NSPSs is controlled by § 306, the provision specifically addressing NSPSs. We disagree. First, because § 304(m)(1) expressly references § 306 and applies to both ELGs and NSPSs, our interpretation of that provision and the duty it creates applies equally to ELGs and NSPSs identified in a plan under § 304(m)(1).
Second, the district court, based on information provided by the EPA, found that "since [§ 304(m) ] was enacted, the EPA has promulgated NSPSs for categories included in [§ 304(m)] plans, but has added no new categories to [the list of categories in § 306]. Hence [§ 304(m) ] seems currently to be the only vehicle by which the EPA identifies new source categories for the purpose of developing NSPSs.” The Defendants have not disputed this finding. We therefore conclude *1251 that because § 304(m) — in its text and in the EPA’s application — grants the EPA the authority to promulgate both ELGs and NSPSs, our analysis here applies equally to both. In light of the above, we need not address industry-intervenors’ suggestion that the Plaintiffs failed to plead a claim for breach of a non-discretionary duty under § 306.
. We need not reach the question of whether the EPA could avoid promulgating ELGs and NSPSs for a point-source category that had, at one time, been included in a § 304(m) plan if the EPA formally amended the § 304(m) plan that triggered the duty to promulgate or undertook some other formal process to delist the point-source category. Here, the EPA has not established that it engaged in any such process but has submitted its statements in its 2004 and 2006 § 304(m) plans that it was "not identifying” the construction industry, which had previously been identified in earlier plans, as a point-source category.
