The American Association of Paging Carriers (AAPC), a trade association representing paging signal carrier companies, seeks review of the September 2004 Memorandum Opinion and Order of the Federal Communications Commission (FCC or Commission) in Amendment of Part 90 of the Commission’s Rules and Policies for Applications and Licensing of Low Poiver Operations in the Private Land Mobile Radio 450-470 MHz Band, 19 F.C.C.R. 18501, 2004 WL 2004465 (2004), reprinted at Joint Appendix (JA) 8a (Denial Order). In the Denial Order, the FCC denied AAPC’s petition to reconsider parts of an earlier rulemaking that revised the channeling plan in the 450-475 MHz band of the radio spectrum, designating eight frequencies in the 462 MHz band for low power communications operations. See Report and Order, 18 F.C.C.R. 3948, 2003 WL 1038402 (2003) (Low Power Order). AAPC claims that by allocating for low power use eight frequencies located at an unacceptably close distance of only 12.5 kHz from existing paging-only frequencies •already designated for use by AAPC’s members, the FCC violated the requirement set out in the 1993 Omnibus Budget Reconciliation Act (OBRA), Pub.L. No. 103-66, 107 Stat. 312, mandating that the Commission make “necessary and practical” modifications to ensure that technical requirements applicable to licensees such as AAPC’s members are “comparable” to those applicable to licensees providing “substantially similar” services. OBRA § 6002(d)(3)(B). Specifically, AAPC claims that the Low Power Order failed to carry out the unambiguous congressional intent expressed in OBRA that like communications services be treated alike. Because we find the Denial Order unreviewable, however, we dismiss AAPC’s petition.

A. Regulation of Commercial Paging Signal Licensing

Paging services allow both commercial subscribers and internal (or “private”1) networks of users to receive messages broadcast by radio waves over dedicated frequencies. Historically, the FCC allocated frequencies for paging operations under two parts of its rules. Part 22 covered the traditional common carrier paging services available to the public known as Public Mobile Services (Part 22 systems), see 47 C.F.R. § 22.99, while Part 90 covered the private paging carrier services known as Private Land Mobile Radio Services (Part 90 systems), including point-to-point private radio services tailored to the needs of particular user groups for internal use — and not subject to common carrier regulation- — such as safety operations (e.g., roadside assistance and volunteer fire departments), systems used by school bus drivers or for disaster relief and businesses requiring specialized internal paging services like private ambulance companies. See 47 C.F.R. §§ 90.15, 90.20. With a growing demand for private service, however, the Commission began authorizing licensees to provide “private carrier” service, i.e., service to third-party users on a for-profit basis, under Part 90.2 *226See Inquiry Relative to the Future Use of the Frequency Band 806-960 MHz, Second Report and Order, 46 F.C.C.2d 752, 755 ¶¶ 6-10, 1974 WL 29789 (1974); Implementations of Sections 3(n) and 332 of the Communications Act, Second Report and Order, 9 F.C.C.R. 1411, 1414 ¶4, 1994 WL 76285 (1994). • As private carrier service was offered to third parties, for profit, and as the FCC permitted private land mobile service operators to interconnect with the public telephone network and thereby provide the same service traditionally offered by common carriers only, private carriers became indistinguishable from common carriers. Nevertheless the two remained subject to separate regulatory schemes. See H.R.Rep. No. 103-111, at 259-60 (1993). Common carriers were subject to rate regulation on both state and federal levels, for example, while private carriers were not. Id. at 260.

In August 1993, the Congress enacted the Omnibus Budget Reconciliation Act (OBRA). Pub.L. No. 103-66, 107 Stat. 312 (1993). Seeking to establish a single regulatory framework for all for-profit mobile radio licensees offering services to the public and a different framework for private licensees, OBRA amended section 332 of the Communications Act of 1934. OBRA section 6002(b) modified the regulation of all mobile radio services, including paging services, by creating two statutorily defined categories of mobile services: commercial mobile radio services (CMRS) and private mobile radio services (PMRS). It' defined CMRS as “any mobile service ... that is provided for profit and makes interconnected service available (A) to the public or (B) to such classes of eligible users as to be effectively available to a substantial portion of the public.” See 47 U.S.C. § 332(d)(1). In response to this congressional mandate, the FCC concluded that all existing common carrier mobile radio services operating under Part 22 of its rules, including common carrier paging services, and a number of the then-private radio services operating under Part 90 of its rules, including private carrier paging services provided by AAPC members, would now be subject to the new CMRS classification.3 Implementations of Sections 3(n) and 332 of the Communications Act, Second Report and Order, 9 F.C.C.R. at 1452-53 ¶ 97, 1994 WL 76285. Through OBRA the Congress also sought to ensure that Part 90 licensees receive substantially similar regulatory treatment as the Part 22 licensees with which they now share the CMRS classification by providing that the Commission, “in the regulations that will, after such date of'enactment, apply to a service that was a private land mobile service and that becomes a commercial mobile service (as a consequence of such amendments), shall make such other modifications or terminations as may be necessary and practical to assure that licensees in such service are subjected to technical requirements that are comparable to the *227technical requirements that apply to licensees that are providers of substantially similar common carrier services.” OBRA § 6002(d)(3)(B).

B. Procedural History

AAPC challenges the FCC’s revision of existing policies governing low power operations in the 450-470 MHz land mobile radio frequency bands.4 Regular channels employing high-power transmissions in these bands are normally spaced 25 kHz apart.5 Recognizing the need for low power operations while at the same time encouraging efficient spectrum use,6 however, the FCC in March 2003 made certain “offset channels” — frequencies only 12.5 kHz removed from the 25 kHz frequencies — available for low power operations.7 Amendment of Part 90 of the Commission’s Rules and Policies for Applications and Licensing of Low Power Operations in the Private Land Mobile Radio 450-470 MHz Band, Report and Order, 18 F.C.C.R. 3948, 3949, 2003 WL 1038402 (2003). The new offset channels, referred to as “Group C” channels in the Low Power Order, were intended for small business use, particularly by individuals like plumbers and electricians who move among fixed job locations and need short-term on-site communications capacity on an “itinerant” basis.8 Id. at 3970-71.

After the Low Power Order issued, AAPC petitioned for reconsideration, requesting the FCC to “eliminate the licensing and use” of the offset frequencies that are only 12.5 kHz removed from eight frequencies used by a number of its members to provide mobile paging services in the 462 MHz band. AAPC Petition for Reconsideration, WT Docket No. 01-146, May 21, 2003, at 7-8. In its petition, AAPC noted that it was a “newly organized national trade association” formed after the comment period for the Notice of Proposed Rulemaking that led to the Low Power Order had closed. Id. at 3. AAPC based its petition for reconsideration on two related grounds: (1) relying on Chevron v. Natural Resources Defense Council, 467 U.S. 837, 104 S.Ct. 2778, 81 L.Ed.2d 694 (1984), it claimed that the allocation of the offset frequencies was “fundamentally inconsistent with the statutory requirement” that “Part 90 CMRS licensees be subjected to technical requirements that *228apply to licensees that are providers of substantially similar common carrier services”; and (2) it maintained the offset frequencies would necessarily subject its members to unreasonable interference, degrading the quality of service provided by Part 90 carriers as compared to Part 22 carriers. Id. at 3-4.

The FCC rejected both grounds.9 It first disagreed with AAPC’s claim that it was statutorily required to ensure that Part 90 paging operations now subject to CMRS regulatory treatment meet the same technical requirements as common carrier paging operations subject to Part 22 of the rules. Denial Order, 19 F.C.C.R. at 18505 ¶ 11. The Commission noted that OBRA section 6002(d)(3) required it to “modify its rules, to the extent ‘necessary and practical,’ to ensure that substantially similar services are subject to ‘comparable’ technical requirements” — not identical requirements — and that the statute confers “substantial discretion on the Commission to determine how this objective should be accomplished.” Id. (citing Further Notice of Proposed Rulemaking, Implementations of Sections 3(n) and 332 of the Communications Act, Second Report and Order, 9 F.C.C.R. 2863, 2864-69 ¶¶ 21-24, 1994 WL 412149). The Commission concluded that it was not required by OBRA “to modify existing rules if such modification is unnecessary to achieve regulatory symmetry or is otherwise impractical.” Id. In addition, because Part 90 paging services were licensed in a different manner from Part 22 paging services and operated on channels that were shared rather than exclusive, AAPC had no support for its view that eliminating the use of offset channels was necessary and practical to make the technical treatment of the two services comparable. Id. Regarding AAPC’s interference challenge, the FCC concluded that it rested on a faulty premise; namely, the reduction of buffer protection from 25 kHz to 12.5 kHz caused interference. The offset frequencies had been available for construction and small business use before the Low Power Order and “the lack of interference complaints [due to use of those frequencies] to date [was] significant.” Id. at 18506 ¶ 13. In addition, the nature of the Part 90 channels also precluded a claim to exclusive use or freedom from interference because Part 90 channels “are available only on a shared basis ... [and] entities [operating on those channels] are not entitled to specific interference protection and should expect other operations in the same area.” Id. The FCC stated that it “continue[d] to believe” that the paging and low power operations could compatibly exist in the 450-470 MHz band, id. at 18506 ¶ 14, and denied AAPC’s petition. AAPC now petitions for review of the denial of its petition for reconsideration.

II.

Both the Communications Act, 47 U.S.C. §§ 402 et seq. (the Act), and the Judicial Review Act, 28 U.S.C. §§ 2341 et seq., provide for our jurisdiction to review Commission decisions. Section 402(a) of the Act governs a proceeding “to enjoin, set aside, annul, or suspend any order of the [Federal Communications] Commission under this Act.” 47 U.S.C. § 402(a): Section 2342 of the Judicial Review Act confers on the court of appeals “exclusive jurisdiction to enjoin, set aside, suspend (in whole or in part), or to determine the validity of ... all final orders of the Federal Communications Commission made reviewable by section 402(a) of title 47.” 28 *229U.S.C. § 2342. The FCC argues that we have no jurisdiction to review the Denial Order because an order that merely denies a petition for agency reconsideration is committed to the agency’s discretion, see 5 U.S.C. § 701(a)(2), and is therefore unreviewable. Sendra Corp. v. Magaw, 111 F.3d 162, 166 (D.C.Cir. 1997) (agency’s denial of request for consideration committed by law to agency discretion and therefore generally unreviewable); ICC v. Bhd. of Locomotive Eng’rs, 482 U.S. 270, 279, 107 S.Ct. 2360, 96 L.Ed.2d 222 (1987) (BLE) (agency’s denial of petition for reconsideration not subject to judicial review if petition alleges only material error in agency’s original decision).10

AAPC posits two theories under either of which, it maintains, its petition is excepted from the nonreviewability rule: (1) the FCC “reopened” the proceeding when it addressed 'the merits of AAPC’s OBRA claim in the Denial Order, see, e.g., Sendra, 111 F.3d at 167; or (2) AAPC’s OBRA claim pressed in its reconsideration petition constitutes “new information” that makes the denial of the petition reviewable. See, e.g., Fritsch v. ICC, 59 F.3d 248, 251-52 (D.C.Cir. 1995) (information provided by petitioner not able to participate in earlier proceeding considered “new evidence” permitting review).

It is true that if an agency issues a new order after reconsideration, the new order constitutes final agency action that is subject to judicial review, even if the new order merely reaffirms the previous decision. BLE, 482 U.S. at 278, 107 S.Ct. 2360 (“When the Commission reopens a proceeding for any reason and, after reconsideration, issues a new and final order setting forth the rights and obligations of the parties, that order — even if it merely reaffirms the rights and obligations set forth in the original order — is reviewable on its merits.”). Reopening, however, does not necessarily occur by dint of the agency’s consideration of the merits. In Sendra we held that an agency order that denies reconsideration and does not alter the original decision is “conclusive” and, unless “the agency has clearly stated or otherwise demonstrated that it has reopened the proceeding,” its denial of reconsideration is only that; “[cjourts will not, in other words, look behind the agency’s formal disposition of the reconsideration request to see whether the agency ‘in fact’ reopened its original decision (and thus rendered a new final order).” Sendra, 111 F.3d at 167 (citing BLE, 482 U.S. at 280-81, 107 S.Ct. 2360) (internal quotations omitted); see also BLE, 482 U.S. at 273, 107 S.Ct. 2360 (irrelevant to reviewability that agency order denying reconsideration discussed merits at length).11

AAPC’s second theory is that its non-participation in the proceeding that produced the Low Power Order means that its petition for reconsideration constitutes “new information” that permits us to review the Denial Order. As AAPC correctly argues, we have found in the past that factual developments that occur post-rule-
