Opinion for the Court filed by Circuit Judge Silberman. Silberman, Circuit Judge: Petitioners, the large long- distance telecommunications carriers, seek review of an FCC order prohibiting them from filing tariffs with the Commis- sion. We reject their petition. I. Commission efforts to move to a nontariff environment for interexchange carriers--insofar as those carriers do not exer- cise market power--have not had an easy time with this court and the Supreme Court. For over six decades a tariff regime was mandated by the Communications Act of 1934, which requires the FCC to review telecommunications carriers' tariffs to ensure their reasonableness. See 47 U.S.C. ss 201- 202. The Act requires carriers to file their tariffs with the FCC, see 47 U.S.C. s 203(a), and they are prohibited from charging consumers except as provided in the tariffs. See 47 U.S.C. s 203(c) (establishing what is popularly known as the "filed-rate doctrine"). Starting in the early 1980s, the Com- mission tried to prohibit tariff-filing by nondominant carri- ers--in essence, those other than AT&T--but that effort was successfully challenged in this court in MCI Telecommunica- tions Corp. v. FCC, 765 F.2d 1186 (D.C. Cir. 1985), where we struck down "mandatory detariffing" as inconsistent with the 1934 Act. There remained some confusion as to whether the FCC's surviving "permissive detariffing" policy for nondominant car- riers--allowing those carriers to choose whether to file tar- iffs--was premised on an agency nonenforcement position, subject to only very limited judicial review, or whether it constituted a substantive regulatory framework. AT&T, by filing a complaint against MCI with the Commission over MCI's non-filing (as it had a right to do under section 208 of the Communications Act, 47 U.S.C. s 208(a)), put the cat among the canaries and forced the Commission, by defending MCI, to embrace the substantive position which we had rejected. The result was more Commission reversals, see American Tel. & Tel. Co. v. FCC, 978 F.2d 727 (D.C. Cir. 1992); American Tel. & Tel. Co. v. FCC, 1993 WL 260778 (D.C. Cir. 1993), this time affirmed by the Supreme Court. See MCI Telecommunications Corp. v. American Tel. & Tel. Co., 512 U.S. 218 (1994). The upshot of all of this was that the Commission simply could not suspend (permissively or mandatorily) the tariff-filing obligations for interexchange carriers, whether they had market power or not. The landscape changed, however, when Congress passed the Telecommunications Act of 1996, which requires the FCC to forbear from applying any regulation or any provision of this chapter to a telecommunications carrier or telecom- munications service, or class of telecommunications carri- ers or telecommunications services, in any or some of its or their geographic markets, if the Commission deter- mines that-- (1) enforcement of such regulation or provision is not necessary to ensure that the charges, practices, classifi- cations, or regulations by, for, or in connection with that telecommunications carrier or telecommunications ser- vice are just and reasonable and are not unjustly or unreasonably discriminatory; (2) enforcement of such regulation or provision is not necessary for the protection of consumers; and (3) forbearance from applying such provision or regula- tion is consistent with the public interest. 47 U.S.C. s 160(a).1 Armed with this new statutory authority, the FCC moved once more to detariff the interstate, domestic, interexchange services of nondominant carriers--now all of the interex- change companies. In a Notice of Proposed Rulemaking, 11 F.C.C. R. 7141 (1996), the Commission tentatively concluded that the 1996 Act required it to "forbear from applying" the tariffing requirement to nondominant carriers, and that per- mitting carriers to file tariffs at all would not be in the public interest. It thus announced its intention to implement man- datory detariffing by "forbearing from applying" s 203(a) of the 1934 Act. Following a comment period the FCC con- firmed that enforcement of the tariffing provision is neither necessary to ensure just and reasonable, nondiscriminatory rates, nor necessary for the protection of consumers, and ordered mandatory detariffing. See Second Report and Or- der, 11 F.C.C.R. 20730, 20742-47, 20750-53 (1996). In their comments, petitioners did not dispute the Commis- sion's tentative conclusion that tariffing was no longer neces- __________ 1 The 1996 Act was passed in the expectation that telecommunica- tions carriers would actively seek detariffing. See 47 U.S.C. s 160(c) ("Any telecommunications carrier, or class of telecommuni- cations carrier, may submit a petition to the Commission requesting that the Commission exercise the authority granted under this section with respect to that carrier or those carriers...."). sary, but argued that the Commission's intention to order mandatory detariffing--rather than permissive detariffing-- both exceeded the Commission's statutory authority and was unreasonable. They claimed that under the 1996 Act the FCC may forbear from enforcing s 203, but cannot actually forbid the filing of tariffs. Petitioners also complained that detariffing would lead to their customer relationships being governed by state contract laws, which, in some cases, might require the execution of a new contract whenever the carrier would want to change its rates. According to petitioners, the necessity of mailing new contracts to customers would in- crease their transaction costs resulting in higher prices for consumers, make casual-calling options more difficult, and hinder their ability to respond quickly to competitors' price changes. See id. at 20755-56.2 If tariffs were permitted, petitioners claimed, they could still negotiate individual con- tracts with large customers, but also file tariffs for millions of mass-market consumers, the optimal result for both groups. In response to objections by consumer groups that carriers might negotiate contracts with individual customers and then rely on the filed-rate doctrine to collect higher tariff rates, petitioners argued that courts would not apply the doctrine because permissive detariffing would gut its rationale: the filed rate would no longer be the only lawful rate. See id. at 20757. The Commission rejected petitioners' statutory and prac- tical arguments. The FCC concluded that outside the filing requirement of s 203(a) there was no provision granting carriers a right to file tariffs, so its forbearance authority under the 1999 Act inherently contemplated mandatory detar- iffing. It found petitioners' proposed distinction between large and small customers immaterial, because the competi- tive benefits of detariffing would be felt by both. The Commission was also concerned that courts might not inter- pret the interplay of permissive detariffing and the filed-rate doctrine quite as petitioners suggested, and that carriers __________ 2 Casual calling refers to collect calls, credit-card calls, or dial- around calling. would use the continued existence of the filed-rate doctrine to refuse to negotiate individualized contracts with customers. The risk that tariffs might serve to facilitate price fixing was also a factor cited by the Commission in its order, but in response to two petitions for reconsideration the Commission abandoned this rationale. See id. at 20760, 20765-67, 20772; Order on Reconsideration, In re Policy and Rules Concern- ing the Interstate, Interexchange Marketplace, 12 F.C.C.R. 15014 (1997); Second Order on Reconsideration and Erra- tum, In re Policy and Rules Concerning the Interstate, Interexchange Marketplace, 14 F.C.C.R. 6004 (1999). Petitioners challenge both the order and the reconsidera- tion orders, and raise before us the same concerns presented to the Commission. They argue that the mandatory detariff- ing order is ultra vires because the FCC lacks statutory authority to forbid the filing of tariffs. Petitioners claim alternatively that the order is arbitrary and capricious be- cause the Commission's preference for mandatory detariffing over permissive detariffing is not supported by facts or logic, the Commission failed to respond to a third alternative ad- vanced by AT&T, and the Commission based its decision in part on a misunderstanding of the filed-rate doctrine. II. We begin with petitioners' argument that the 1996 Act does not give the FCC authority to implement mandatory detariff- ing--it cannot forbid the filing of tariffs. The Act states that the FCC "shall forbear from applying any regulation or any provision of this chapter ... if the Commission determines that (1) enforcement ... is not necessary [to ensure rates are just, reasonable, and nondiscriminatory], (2) enforcement ... is not necessary for the protection of consumers, and (3) forbearance from applying such provision or regulation is consistent with the public interest." 47 U.S.C. s 160(a) (em- phasis added). Petitioners urge that under the plain lan- guage of the statute the Commission is empowered merely to exercise its discretion not to enforce a provision under such circumstances. In other words, to forbear is to "refrain from action," see Pet. Br. at 17 (citing, e.g., Black's Law Dictionary 329 (5th ed. 1983)); nonenforcement is therefore forbearance, but barring the doors of the FCC to lawyers bearing tariff filings and throwing out extant tariffs, both affirmative acts, are not. Petitioners offer in support of their interpretation our opinion in American Telephone & Telegraph, where we stated that the FCC "went beyond mere forbearance ... by making detariffing mandatory and by telling non-dominant carriers that it would no longer even accept their rate filings...." 978 F.2d at 729-30. But we ourselves have used the word forbear in two different ways. In MCI Telecommunications, we said "forbearance was made mandatory" and the Commis- sion "changed the permissive forbearance arrangement into a mandatory one." 765 F.2d at 1191 n.4, 1189. So it is hardly open to us to deny the ambiguity which accompanies the statutory use of that term--particularly when Congress acted against a backdrop of our decisions. Moreover, the crucial phrase in the statute is not "forbear from enforcing" but rather "forbear from applying," which suggests a broader authority. As the Commission correctly points out no provi- sion of the Communications Act except s 203(a) requires tariffing, and no provision gives a carrier a positive right to file a tariff, so if it forbears from applying s 203(a) the Commission's staff is not obliged to accept filings. We there- fore think that the Commission's interpretation of the Act is entitled to Chevron deference. See Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc., 467 U.S. 837 (1984).3 Petitioners alternatively claim that the Commission's order is arbitrary and capricious, and, to use the Act's terminology, against the "public interest" because its stated objectives easily can be met by adopting a permissive-detariffing re- gime, and therefore the extra transaction costs imposed on the carriers--and passed through to consumers--are unnec- __________ 3 Petitioners seem to argue that the delegation of the authority to "forbear" implicitly precludes authority to forbid but that is even more of a stretch. essary. The major thrust of petitioners' arguments is that the Commission inadequately responded to their comments, and therefore the case should be remanded to the FCC so as to require the agency to do so. (It is worth noting that we have stayed the Commission's order so the status quo favors the petitioners for so long as they can maintain it.) The Commission, as we have mentioned, wishes to disen- tangle the interexchange carriers' prices from the filed-rate doctrine. The Commission has long been concerned that the necessity of filing tariffs hinders competitive responsiveness. And, according to consumer representatives' comments pre- sented to the FCC, the filed-rate doctrine has been used by the carriers as a shield to avoid individual contract negotia- tions with large and small users, thereby reducing competi- tion among carriers. Petitioners argue that streamlined tar- iff procedures already adopted by the FCC, see Tariff Filings Requirements for Nondominant Common Carriers, 8 F.C.C.R. 6752 (1993), and carriers' ability to file tariffs for individual consumers have obviated those concerns. But the Commission reasonably disagreed, in part relying on the consumers' reported experience under those procedures, and in part because it was wary that the filed-rate doctrine might be interpreted by state and federal courts to interfere with free-market behavior. See Second Report and Order, 11 F.C.C.R. at 20760-61; 20766-67. Perhaps the most interesting argument in the case relates to an AT&T ex parte letter (suitably filed) sent after the comment period ended. In a rather downplayed alternative argument AT&T suggested in a single paragraph that if the Commission's interpretation of forbearance was legitimate (which of course AT&T denied) the Commission could elimi- nate certain problems with tariffs--and thereby move to only permissive detariffing--if it would forbear from enforcing--or even forbid the application of--the filed-rate doctrine, 47 U.S.C. s 203(c). The Commission did not respond to this rather subtle suggestion and petitioners contend that that failure alone requires a remand. The FCC argues that AT&T's comment was only a throwaway, inconsistent with petitioners' primary argument that mandatory forbearance is ultra vires, and not even part of its formal comment, so we should not regard the issue as properly presented to the Commission under 47 U.S.C. s 405(a). If that were so, we would not have jurisdiction to consider the point. We do not think that is quite correct, although it is a close question. Petitioners note that the Commission's order refers to several ex parte filings received after the filing in issue here. See Second Report and Order, 11 F.C.C.R. at 20781-82 nn. 253 & 254. AT&T's filing was not long, and the relevant paragraph concluded a discussion on one of the key issues of the proceeding: whether the filed-rate doctrine would be an impediment to permissive detariffing. The paragraph--even though presented as an alternative argument--does suggest that forbearance from s 203(c) would eliminate the possibility of carriers' invoking the filed-rate doctrine. Therefore, we think the argument was presented--if barely--to the Com- mission. Still, it is one thing to preserve a point for judicial review and quite another to raise the issue with sufficient force to require an agency to formally respond. An agency is not obliged to respond to every comment, only those that can be thought to challenge a fundamental premise. See Grand Canyon Air Tour Coalition v. FAA, 154 F.3d 455, 468 (D.C. Cir. 1998) ("An agency must ... demonstrate the rationality of its decisionmaking process by responding to those com- ments that are relevant and significant.") (emphasis added). In this case, AT&T's late ex parte alternative comment does not seem to us to be forceful enough to have obliged the Commission to squarely confront it. Certainly the Commis- sion made clear its concern that if tariffs were permitted it could not foresee how the judiciary (in this case, probably state courts) would treat the filed-rate doctrine. It seems obvious to us that the Commission would not have wished to risk the doctrine's continued employment even had AT&T's device been tried.4 __________ 4 Since the filed-rate doctrine is applied by courts, even if it has its genesis in the 1934 Act, the Commission's concern about the Moreover, as we read the Commission's decision the es- sence of its reasoning was a desire to put the interexchange carriers under the same market conditions as apply to any other nonregulated provider of services in our economy. The Commission concluded that "a regime without nondominant interexchange carrier tariffs for interstate, domestic, interex- change service is the most pro-competitive, deregulatory sys- tem." Second Report and Order, 11 F.C.C.R. at 20760. It thought the public interest would best be served by "estab- lishing market conditions that more closely resemble an unregulated environment." See id. It noted that the "par- ties that oppose complete detariffing have not shown that the business of providing interstate, domestic, interexchange ser- vices offered by nondominant interexchange carriers should be subject to a regulatory regime that is not available to firms that compete in any other market in this country." Id. at 20763. And, importantly, the Commission found that permitting carriers to file tariffs on a voluntary basis would undermine the competition-enhancing effect of detariffing. See id. at 20760.5 Under such circumstances, remand is not necessary for the agency to consider the proposed alternative. See Center for Science in the Public Interest v. Department of the Treasury, 797 F.2d 995, 1004 (D.C. Cir. 1986). Tariff filing, in other words, in the Commission's view is an undesirable deviation from the market--at least where there are no market imperfections. Petitioners contend that the Commission could not foreclose a permissive detariffing with- out more justification than simply a desire to embrace the free market. We think, however, the Commission was enti- tled to value the free market, the benefits of which are rather well established. Indeed, the 1996 Act provides that "[i]f the Commission determines that ... forbearance will promote __________ filed-rate doctrine is not unreasonable and is certainly not, as petitioners claim, legally erroneous. 5 The agency rejected an alternative similar to AT&T's without even referring to the danger of judicial mishandling of the filed-rate doctrine; the focus was squarely on competition. See id. at 20766- 67. competition ... that determination may be the basis for a ... finding that forbearance is in the public interest." 47 U.S.C. s 160(b). It was certainly reasonable to move regulation in that direction even if it ostensibly raises transaction costs for the carriers.6 * * * * The petition for review is denied. So ordered. __________ 6 The Commission did not, as petitioners contend, ignore the probability of increased transaction costs. It simply found them insignificant compared to the competitive benefits of detariffing. See Second Report and Order, 11 F.C.C.R. at 20764.
