Opinion

MEMORANDUM OPINION

JAMES E. BOASBERG, United States District Judge

Dental amalgam is a metallic compound that dentists use to fill cavities and repair structural deformities in teeth. One of its constituent parts is mercury. The Plaintiffs in this suit, which include a number of individuals and several not-for-profit organizations, fear that mercury renders the compound physically harmful, both for the individuals obtaining fillings and for the déntists responsible for installing and removing them. They áre also concerned that the removal of such 'fillings (also known as silver fillings) may cause "environmental harm, as they assert that dental-amalgam particulate travels from patients’ mouths to sinks and then to sewers, ultimately contaminating the nation’s water supply.

Hoping to take a large bite out of the prevalence of dental amalgam, some of the Plaintiffs asked the Food and Drug Administration to either ban it outright' or classify it as high risk, thereby triggering a greater degree of regulatory scrutiny. The FDA rejected these various entreaties. Plaintiffs then brought suit here, asking this Court to compel the FDA to take a considerably stronger regulatory position, including conducting an evaluation of amalgam’s environmental impact. Before getting to the root of Plaintiffs’ claim, however, the Court must determine whether they have standing to sue. Concluding that they do not, the Court will grant Defendants’ Motion to Dismiss.

I. Background

As the FDA’s duties play an important role in this suit, the Court will first summarize the agency’s responsibility for regulating dental devices and set out the regulatory history of dental amalgam. It'will then recount the various efforts taken by *249 some of the Plaintiffs to seek recourse directly from -the FDA and end -with a summary of the case’s procedural history, including events that transpired subsequent to the filing of the Complaint.

A. Statutory Framework

Ever since passage of the 1976 Medical Device Amendments (MDA) to the Food, Drug and Cosmetic Act (FDCA), see Pub.L. No. 94-295, 90 Stat. 539 (1976), the FDA has had authority to regulate devices that, among other things, are “intended to affect the structure or any function of the body of man.” 21 U.S.C. § 321(h)(3). Under the statute, any device may be categorized into one of three classes: I, II, or III. “A device’s classification is determined based on ‘the degree of regulation thought necessary to provide reasonable assurance of each device’s “safety and effectiveness.” ’ ” Ivy Sports Med., LLC v. Burwell, 767 F.3d 81, 83 (D.C.Cir.2014) (quoting Contact Lens Manufacturers Association v. FDA, 766 F.2d 592, 594 (D.C.Cir.1985), itself quoting 21 U.S.C. § 360c). Pursuant to the MDA, the FDA has classified a variety of tools and materials used in dentistry as “devices.” See generally 21 C.F.R. Part 872 (1988).

The minutiae of the classification regime are immaterial for present purposes, and it is sufficient to explain that “Class I and II devices are considered to pose fewer risks,” Ivy Sports Med., 767 F.3d at 83, meaning they demand fewer and less taxing regulatory controls. “The devices receiving the most federal oversight,” in contrast, “are-those in Class III,” which consist of “devices that present great risks [but] nonetheless offer great benefits in light of available alternatives.” Riegel v. Medtronic, Inc., 552 U.S. 312, 317, 318, 128 S.Ct. 999, 169 L.Ed.2d 892 (2008).

Class I devices are regulated by the imposition of “ ‘general controls,’ such as labeling requirements.” Id. at 316, 128 S.Ct. 999. Class II devices are, in addition to “general controls,” subject to “ ‘special controls’ such as performance standards and postmarket surveillance measures.” Id. at 316-17, 128 S.Ct. 999. Finally, Class III devices require rigorous pre-market evaluations and assessments to determine the product’s safety, see id. at 317, 128 S.Ct. 999, and to ensure that the device “be made with almost no deviations from the specifications [furnished in the device’s] approval application, for the reason that the FDA has determined that the approved form provides a reasonable assurance of safety and effectiveness.” Id. at 323,128 S.Ct. 999.

B. Dental Amalgam

“Dental amalgam” is a single device, but it is made up of two component parts, both of which are FDA-regulated devices in their own right: (a) elemental or “dental” mercury, and (b) amalgam alloy, which is mostly composed of silver, tin, and copper. See Dental Devices: Classification of Dental Amalgam, Reclassification of Dental Mercury, Designation of Special Controls for Dental Amalgam, Mercury, and Amalgam Alloy, 74 Fed. Reg. 38686, 38696 (Aug. 4, 2009). Manufacturers of dental amalgam prepare and sell pre-dosed capsules containing those two components, which allows a dentist to mix them together in her office when installing a filling. See id. at 38696. The FDA formerly referred to this composite device as “encapsulated amalgam alloy and dental mercury,” 67 Fed Reg. 7620, 7621 (Feb. 20, 2002), but it is now known more pithily as “dental amalgam.” 74 Fed. Reg. at 38686.

Shortly after Congress enacted the MDA in the late 1970s, the FDA began the process of classifying the two sub-components of dental amalgam separately. See Classification of Dental Devices; Development of General Provisions, 45 Fed Reg. *250 85962 (Dec. 30, 1980) (Proposed Rule). In 1987, the agency promulgated a final rule classifying elemental mercury—then known as “dental mercury”—as a Class I device, and amalgam alloy as a Class II device. See Dental Devices; General Provisions and Classifications of 110 Devices, 52 Fed. Reg. 30082, 30084-85 (Aug. 12, 1987).

Unfortunately, “[d]ue to an inadvertent error,” the FDA neglected to propose classification of the combined form, dental amalgam, in the 1980s rulemaking process. See 67 Fed. Reg. at 7621. It nevertheless decided at that time to treat dental amal-gám as a Class II device, since one of its components, amalgam alloy, was regulated as Class II, even though the remaining components were regulated as Class I. See id.; 52 Fed. Reg. at 3099, 30102; see also Moms Against Mercury v, FDA, 483 F.3d 824, 825 (D.C.Cir.2007) (recounting history of dental amalgam); Comm. of Dental Amalgam Mfrs. & Distributors v. Stratton, 92 F.3d 807, 811 (9th Cir.1996) (recognizing and approving FDA’s treatment of dental amalgam as a regulated device even though it had not been classified separately from its “component parts” dental mercury and amalgam alloy).

C. Plaintiffs’ Citizen Petitions

Plaintiffs comprise a hodgepodge of individuals and organizations, all of whom in some way oppose the use of mercury in dental fillings. The Court will not provide extensive details on these various entities and individuals until later in this Opinion, as the briefing has clarified that only a subset of the full list of Plaintiffs possesses a colorable argument that they have standing to sue.
