83 In the Order, the Commission decided to forbear from numerous provisions of the Communications Act. 2015 Open Internet Order, 30 FCC Rcd. at 5616 ¶ 51. Full Service Network raises both procedural and substantive challenges to the Commission’s forbearance decision. None succeeds. A. Full Service Network first argues that the Commission should have followed its regulatory requirements governing forbearance petitions even though it forbore of its own accord. In the Order, the Commission rejected this contention, stating that “[b]ecause the Commission is forbearing on its own motion, it is not governed by its procedural rules insofar as they apply, by their terms, to section 10(c) petitions for forbearance.” Id. at 5806 ¶ 438. “[W]e review an agency’s interpretation of its own regulations with ‘substantial deference.’” In re Sealed Case, 237 F.3d 657, 667 (D.C. Cir. 2001) (quoting Thomas Jefferson University v. Shalala, 512 U.S. 504, 512 (1994)). The agency’s interpretation “will prevail unless it is ‘plainly erroneous or inconsistent’ with the plain terms of the disputed regulation.” Everett v. United States, 158 F.3d 1364, 1367 (D.C. Cir. 1998) (quoting Auer v. Robbins, 519 U.S. 452, 461 (1997)). The Commission’s interpretation of its regulations easily satisfies this standard. By their own terms, the regulations apply to “petitions for forbearance,” and nowhere say anything about what happens when, as here, the Commission decides to forbear without receiving a petition. See 47 C.F.R. § 1.54. To the extent this silence renders the regulations ambiguous in the circumstance before us, the Commission’s interpretation is hardly “plainly erroneous.” Everett, 158 F.3d at 1367 (internal quotation marks omitted).
