Opinion for the court filed by Circuit Judge Sentelle.

Sentelle, Circuit Judge: These petitions seek review of a
Federal Communications Commission decision permitting lo-
cal telephone companies (known as "local exchange carriers"
or "LECs") to assess End User Common Line ("EUCL")
charges on an independent payphone provider. Petitioners--
the independent payphone provider and a trade association of
independent payphone providers--argue that the Commission
misinterpreted its rules to arrive at its decision. We agree,
and grant the petitions for review.

I. Background

A.

When a telephone customer places a call, a "loop" links the
telephone to the central office of a local exchange carrier,
where switching equipment routes the call to a local or long-
distance telecommunications network. Most of the LECs'

costs in operating their facilities do not vary depending on
how often the facilities are used; such costs are known as
"nontraffic sensitive" ("NTS") costs. The cost of installing
the loop is an NTS cost, for example, because that cost
remains the same whether a customer uses the loop to make
one call or one hundred calls. See National Ass'n of Regula-
tory Util. Comm'rs v. F.C.C., 737 F.2d 1095, 1104 (D.C. Cir.
1984). In contrast, the cost of the switching equipment tends
to increase with use, and is considered to be traffic-sensitive.
Id.

In 1983, the Commission released rules governing the
charges through which LECs would be compensated for
providing long-distance carriers (known as "interexchange
carriers" or "IXCs") with access to their local exchange
facilities. In re MTS and WATS Market Structure, Third
Report and Order, 93 F.C.C.2d 241, 242-43 (1983) ("Access
Charge Order"), modified on recon., 97 F.C.C.2d 682 (1983)
("Access Charge Reconsideration"), modified on further re-
con., 97 F.C.C.2d 834 (1984), aff'd and remanded in part sub
nom. National Ass'n of Regulatory Util. Comm'rs v. F.C.C.,
737 F.2d 1095 (D.C. Cir. 1984). The Commission decided
that, as a general matter, "end users" placing interstate calls
should bear the cost of the access charges. Therefore, the
Commission's rules provided that most subscribers were as-
sessed a monthly, flat-rate charge for the "end user common
line" element, permitting LECs to recover a significant
amount of the NTS costs associated with the subscribers'
loops.

In crafting its rules, the Commission faced a dilemma: how
to permit LECs to recover their investment in the public
payphones (and payphone lines) that they owned and operat-
ed. Payphones required special treatment, reasoned the
Commission, because the end users of payphones consisted of
the "transient general public," rather than the subscribers, as
in the case of private business or residential telephones. See
In re C.F. Communications Corp. v. Century Telephone of
Wisconsin, Inc., 8 F.C.C.R. 7334, 7335 p 10 (Com. Car. Bur.
1993) ("Bureau Order"). At first, the Commission deter-
mined that LECs would recover their payphone investments

solely through coin calls placed by end users. Access Charge
Order at 280. Under this solution, however, LECs were not
able to recover their investment from the many end users
who used payphones to make non-coin calls, such as collect,
credit card or third-party calls, causing either an inadequate
recovery for the LECs or a disproportionate burden on end
users paying by coin. Access Charge Reconsideration at 705.

On reconsideration, the Commission decided not to assess
any charge on end users of public payphones. Rather, the
Commission decided that LECs would recover the NTS costs
of operating their payphones and payphone lines from a
carrier common line element, which in turn was recovered
from the switched access charges imposed on IXCs and
interstate calls in general. Id. In other words, the Commis-
sion decided that public payphone users would no longer pay
for the NTS costs of operating public payphones, but that
those costs would in effect be subsidized by all interstate
callers.

The Commission, however, did not exempt all payphones
from EUCL charges. Although it excused "public" pay-
phones from the charge, it determined that "semi-public"
payphones would be subject to the charge. When it original-
ly announced the public/semi-public distinction, the Commis-
sion explained that "[a] pay telephone is used to provide
semipublic telephone service when there is a combination of
general public and specific customer need for the service,
such as at a gasoline station or pizza parlor. [Local telephone
companies] provide directory listing with this service." Id. at
704 n.40. By contrast, "[a] pay telephone is used to provide
public telephone service when a public need exists, such as at
an airport lobby, at the option of the telephone company and
with the agreement of the owner of the property on which the
phone is placed." Id. at 704 n.41. The Commission deter-
mined that NTS costs associated with semi-public payphones
should be "recovered from subscribers to that service in the
same manner that costs associated with an ordinary business
subscriber line are recovered" because "[t]hose fixed costs
can be recovered from an identifiable business end user
through flat charges." Id. at 706.

At the time the Commission developed this scheme for
payphone access charges, the only existing payphones were
owned by LECs. LEC-owned payphones are connected by
special "coin lines" to an LEC central office. A processor
located at the central office then does most of the work:
determining the cost of the call, timing the call, telling the
user how much money to deposit, and performing additional
tasks. Because they are not capable of processing and
supervising calls on their own, LEC-owned payphones are
considered to be "dumb."

In 1984, the Commission permitted payphones not owned
by LECs to enter the market. Unlike LEC-owned pay-
phones, the new independent payphones were "smart," ca-
pable of processing and supervising calls by means of a
microprocessor located inside the phone. These "smart"
payphones were attached to ordinary telephone lines; be-
cause they were self-sufficient, there was no need for spe-
cial "coin lines" to link them to an LEC central office.
Callers encounter independent payphones in the same
places where they would find LEC-owned payphones, such
as street corners, airports, shopping malls, and rural "mom
and pop" stores. Since callers are not able to tell whether
a given payphone is "smart" or "dumb," from a caller's
point of view, independent payphones are indistinguishable
from those owned and operated by LECs.

B.

Petitioner C.F. Communications Corporation ("CFC") oper-
ates independent payphones in Wisconsin, Michigan, Minne-
sota and Iowa. On May 10, 1989, CFC filed a complaint with
the Commission challenging several LECs' imposition of
EUCL charges on CFC's independent payphones. Petitioner
American Public Communications Council, Inc., a trade asso-
ciation of the independent payphone industry, intervened in
and participated in the complaint proceeding on CFC's behalf.

In its complaint, CFC argued that it should be excused
from EUCL charges because it did not qualify as an "end
user" under the Commission's rules. CFC also argued that

its payphones should be classified as "public"--and therefore
exempt from EUCL charges--because they were located in
public places and accessible to all members of the public.
Accordingly, CFC sought damages from the LECs in the
amount of the EUCL payments it had made to them.

The FCC's Common Carrier Bureau rejected CFC's argu-
ments, and held that the LECs had properly assessed EUCL
charges on CFC's independent payphones. See Bureau Or-
der. In the Order challenged in this case, the Commission
affirmed the Bureau's decision. See In re C.F. Communica-
tions Corp. v. Century Telephone of Wisconsin, Inc., 10
F.C.C.R. 9775 (1995) ("Order"). The Commission found that
CFC was an "end user" under its rules, and thus subject to
EUCL charges. Specifically, the Commission found that
CFC met the regulatory definition of "end user" because it
"offers telecommunications services exclusively as a reseller"
and that all such resale transactions "originate on [CFC's]
premises." See 47 C.F.R. s 69.2(m).

The Commission further concluded that CFC's independent
payphones did not qualify for the "public telephone" exemp-
tion from the EUCL charges. Relying on an FCC rule
defining "public telephone" as being "provided by a telephone
company," 47 C.F.R. s 69.2(ee), the Commission reasoned
that CFC's payphones were not "public" because CFC is not
a "telephone company" under the applicable rules. See 47
C.F.R. s 69.2(hh). In addition, the Commission deemed
CFC's payphones to be "semi-public" because--regardless of
how they were actually used--they were capable of private
use. Order at 9780, p 21.

C.

The Telecommunications Act of 1996 became law on Febru-
ary 8, 1996. Pursuant to the Act, the Commission initiated a
rulemaking proceeding to revise its rules governing pay-
phones. On September 20, 1996, and in several subsequent
orders on reconsideration, the Commission required the pro-
spective application of EUCL charges to both independent
payphones and to LEC-owned payphones. The Commission's

decision had no effect on the challenged EUCL charges that
CFC incurred prior to the effective date of the new rules.

II. Discussion

As a liminal matter, we note that we accord great deference
to an agency's interpretation of its own rules. Our deference
under these circumstances has sometimes been described as
even greater than our deference to an agency's interpretation
of ambiguous statutory terms. See Capital Network System,
Inc. v. F.C.C., 28 F.3d 201, 206 (D.C. Cir. 1994) (citing Udall
v. Tallman, 380 U.S. 1, 16 (1965)). An agency's interpreta-
tion of its own rule " 'becomes of controlling weight unless it
is plainly erroneous or inconsistent with the regulation.' " Id.
(quoting United States v. Larionoff, 431 U.S. 864, 872 (1977)).

Here, the Commission interpreted its rules to find that (1)
CFC is an "end user" subject to EUCL charges; and (2)
CFC's payphones are not "public telephones" and therefore
do not qualify for the "public telephone" exemption from
EUCL charges. Keeping in mind our great deference to the
Commission's interpretation of its rules, we review the Com-
mission's interpretations below.

A.

As its name implies, the End User Common Line charge is
assessed on an "end user." 47 C.F.R. s 69.5(a) ("End user
charges shall be computed and assessed upon end
users...."). Under the Commission's access charge rules, an
"end user" is defined as:

[A]ny customer of an interstate or foreign telecommuni-
cations service that is not a carrier except that a carrier
other than a telephone company shall be deemed to be an
"end user" when such carrier uses a telecommunications
service for administrative purposes and a person or
entity that offers telecommunications services exclusively
as a reseller shall be deemed to be an "end user" if all

resale transmissions offered by such reseller originate on
the premises of such reseller.

47 C.F.R. s 69.2(m).

It is not disputed that CFC, a reseller of LEC services,
qualifies as a "carrier" under this rule. Bureau Order at
7336, p 12; Order at 9777, p 10. As a "carrier," CFC is
deemed to be an "end user" if it meets one of the two
conditions listed above. According to the Commission, CFC
is an "end user" because it meets the second condition: it
"offers telecommunications services exclusively as a reseller,"
and "all resale transmissions offered by such reseller origi-
nate on the premises of such reseller." 47 C.F.R. s 69.2(m).

To determine if all of CFC's transmissions originate "on
the premises of [CFC]," the Commission analyzed the word
"premises," which is not defined in the Commission's rules.
Observing that the word "does not have a single fixed mean-
ing" and is "defined according to its context," Order at 9778,
p 13, the Commission found that in the context of Section
69.2(m), "premises" means "the place where, in most cases,
the equipment of the reseller is located and where the use of
the resold telecommunications services must originate." Id.
at 9779, p 17. Under this reading, every location where CFC
contracts to place a payphone would be considered CFC's
"premises."

While the Commission is correct that the word "premises"
"does not have a single fixed meaning," accord Gibbons v.
Brandt, 170 F.2d 385, 387 (7th Cir. 1948); O'Connor v. Great
Lakes Pipe Line Co., 63 F.2d 523, 525-26 (8th Cir. 1933), this
fact does not convert the word into a sort of Rorschach test,
permitting the Commission to read into the word anything it
pleases. We find that the Commission's interpretation of the
word "premises" is so far removed from any established
definition of that word that we must reject its interpretation
as plainly erroneous.

CFC's payphones are the personal property of CFC. An
agreement between CFC and the Central Wisconsin Airport
of the City of Mosinee, which is "typical" of CFC's agree-

ments with other location owners, Skrypczak Affidavit p 5,
explicitly states that CFC owns the payphones, and that the
"[t]elephones, booths and equipment are ... personal proper-
ty."

The term "premises," as used in this context, traditionally
refers to real property and its appurtenances. Black's Law
Dictionary 1062-63 (5th ed. 1979). Black's Law Dictionary
defines the term as "[a] distinct and definite locality, and may
mean a room, shop, building, or other definite area, or a
distinct portion of real estate." No matter how flexible the
meaning of "premises" may be, an item of personal property
may not sensibly be construed to be a "locality," a "definite
area," or a "distinct portion of real estate." Assuming a
payphone could be considered "premises" as appurtenant to
land, that would not make CFC's payphones the premises of
the company as CFC neither owns nor controls the land or
buildings on which its payphones are sited. The Commission
has provided no definition under which personal property
located on real property owned by another is considered to be
"premises," and we are aware of none.

The Commission, alternatively, suggests that "premises"
means the land or buildings on which CFC's payphones are
located. Order at 9778, pp 14-15. Recognizing that others
actually own the land or buildings on which the payphones
are located, the Commission found it significant that CFC had
what it termed "limited legal control" over the land or
buildings on which its payphones were located. The Commis-
sion did not explain the nature or source of this limited
control, but found that its existence justified treating the land
or buildings as CFC's "premises," even if CFC did not own
the land. Id. In other words, the Commission decided to
treat land owned by someone else as the "premises" of CFC
on the theory that CFC acquired an interest in the property
by contracting to place its payphone there. In so doing, the
Commission has not only distorted the plain meaning of
"premises" beyond any reasonable interpretation of the word,
but has rendered the phrase "originate on the premises of the
reseller" virtually meaningless. If any location in which a
"reseller" has the capacity to originate a call becomes its

premises, that requirement of the rule excludes nothing. The
Commission's interpretation, then, violates the familiar princi-
ple of statutory interpretation which requires construction "so
that no provision is rendered inoperative or superfluous, void
or insignificant." Mail Order Ass'n of America v. United
States Postal Service, 986 F.2d 509, 515 (D.C. Cir. 1993)
(internal quotations and citations omitted).

We do not suggest that the Commission could not amend
its rules to render "premises" a term of art encompassing
telephone equipment or land owned and controlled by a third
party on which telephone equipment is located. But to do so,
it must use the notice and comment procedure of the Admin-
istrative Procedure Act. It may not bypass this procedure by
rewriting its rules under the rubric of "interpretation." See
Indiana Michigan Power Co. v. Dept. of Energy, 88 F.3d
1272, 1276 (D.C. Cir. 1996) ("The [agency's] treatment of this
statute is not an interpretation but a rewrite."). In this case,
the Commission's interpretation of Section 69.2(m) does not
comport with the plain meaning of the term "premises" and
must be rejected.1

B.

In addition to our conclusion that the Commission erred in
determining that CFC was an "end user," we also hold that
petitioners are entitled to the relief sought for the alternate
reason that the Commission improperly discriminated be-
tween similarly situated phone services without a rational
basis. As we noted earlier, public telephones are not subject
to EUCL charges under the Commission's Access Charge
Reconsideration decision. In determining that CFC's pay-
phones were not subject to the "public telephone" exclusion,
the Commission relied on the following definition of "public
telephone": a "telephone provided by a telephone company
through which an end user may originate interstate or foreign

__________
1 Having determined that the Commission's interpretation of
"premises" fails to pass muster, we need not address its conclusion
that CFC "offers telecommunications services exclusively as a re-
seller" under Section 69.2(m). Order at 9779, p 18.

telecommunications for which he pays with coins or by credit
card, collect or third number billing procedures." 47 C.F.R.
s 69.2(ee) (emphasis added). Finding that CFC is not a
"telephone company," the Commission determined that CFC's
payphones did not qualify for the EUCL fee exemption.
Order at 9779-80, pp 19-20.

CFC concedes that it is not a "telephone company" under
Section 69.2(ee), but argues that the Commission improperly
applied that definition in this context. It observes that
Section 69.2(ee) was promulgated without explanation several
years after the Commission adapted its access charge rules,
and further observes--and the Commission does not dis-
pute--that the Commission drafted this definition with anoth-
er purpose in mind: clarifying the rules on allocation of
LECs' own investments in payphone equipment to particular
access charge elements.

We agree that the Commission's reliance on the definition
of "public telephone" in Section 69.2(ee) does not provide
sufficient justification for its distinction between CFC's pay-
phones and those operated by LECs. See Corporate Telecom
Services, Inc. v. F.C.C., 55 F.3d 672, 677 (D.C. Cir. 1995)
(rejecting the FCC's citation of "rules [which] appear to have
been designed with completely different purposes in mind").
When considered in its intended context, Section 69.2(ee)
makes sense: the Commission defined "public telephone" to
exclude independent payphones to clarify that, under the
rules governing LECs' recovery of their investment in pay-
phone equipment, LECs were not entitled to recover indepen-
dent payphone costs. In other words, Section 69.2(ee) makes
it plain that LECs may recover only their investment in
"public telephones" which they own and control, not in inde-
pendent telephones which are owned by others. However,
the Commission has shown no rational connection between
Section 69.2(ee) and the public/semi-public telephone distinc-
tion in its Access Charge Reconsideration decision. As ex-
plained earlier, the Commission exempted public payphones
from EUCL charges because it recognized that there was no
practical way to ensure that NTS costs were being shared
equally by all interstate end users of those payphones. In

light of the Commission's reasons for introducing the
public/semi-public distinction, we find that it has not shown
any legally significant difference between "public" payphones
owned by an LEC and those of the independent payphone
providers.

The Commission simply--and, we think, unreasonably--
ignored context and stated that "we must apply our rules as
they are now codified." Order at 9780, p 20. The Commis-
sion put on blinders after it found that CFC did not meet its
definition of "public telephone," not acknowledging that the
definition had been adopted in a different context; that the
"public telephone" exemption to the EUCL charges was
introduced in a Commission order, not in its rules; and that
the Section 69.2(ee) definition of "public telephone" was incon-
sistent with the original rationale for introducing the exemp-
tion in the Access Charge Reconsideration decision. We find
that the Commission's interpretation is not "reasoned," see
Corporate Telecom Services, 55 F.3d at 675 (rejecting FCC's
rule interpretation as inconsistent with the "values the provi-
sion is supposed to embody"), and therefore reject its conclu-
sion that CFC's payphones are not "public telephones" for
purposes of the exclusion from EUCL charges.

C.

Having found that CFC's payphones did not qualify for the
exclusion because they were not "public telephones," the
Commission declared that CFC's payphones were ineligible
because they were "semi-public." Order at 9780, p 21. Re-
jecting petitioners' request that it should decide if the pay-
phones were public or semi-public by examining how the
payphones were used, the Commission found it "more rele-
vant to examine how [CFC's] payphone lines can be used."
Id. (emphasis in original). The Commission then found that
CFC's payphones were capable of private use because, like
conventional telephones, they were connected to regular sub-
scriber business lines. This technical point--that CFC's pay-
phones were connected to regular subscriber business lines as

opposed to the coin lines attached to LEC-owned pay-
phones--was the Commission's sole reason for finding that
CFC's payphones were semi-public and not qualified for the
EUCL charge exemption. Bureau Order at 7336, p 13; Or-
der at 9780, p 21. The Commission attempts to justify its
distinction by arguing that under the Access Charge Recon-
sideration decision the existence of an "identifiable subscrib-
er" was the most important factor in determining that pay-
phones were public rather than semi-public.

The Commission has not adequately justified the distinction
it has drawn between CFC's payphones and LEC-owned
payphones. First, the Commission improperly relies on the
Access Charge Reconsideration decision. In that decision,
the Commission rejected its earlier approach of assessing a
per-call charge on payphone callers to recover the interstate
NTS costs of the payphone line, observing that it would be
inequitable for those who used coins to make payphone calls,
representing "only a fraction of those using pay telephones,"
to bear the cost of the EUCL charges. Access Charge
Reconsideration at 704. Recognizing that the "ideal solution"
of recovering NTS costs of public payphones from "end users
who rely upon pay phones to originate their interstate calls"
was not technologically feasible, the Commission decided
instead to eliminate the per-call charge on public payphone
users entirely. Id. at 705. The Commission, then, created an
exemption for public payphones because, due to the transient
nature of payphone users, there was no ultimate end user
from whom the charge could be recovered equitably. Thus,
notwithstanding the Commission's argument to the contrary,
the existence of an identifiable subscriber was not the control-
ling factor in its decision to exempt public payphones from
the EUCL charge, as the caller, not the subscriber, is the
ultimate end user in any event.

More importantly, even if the Commission had originally
justified its distinction between public and semi-public pay-
phones on the ground that semi-public payphones are subject
to EUCL charges because of the existence of an identifiable
subscriber, such an approach does not adequately explain why
the Commission exempted LEC-owned payphones from the

EUCL charge, but treated CFC's payphones as subject to the
charge. After all, the Commission's express reason for ex-
empting public payphones from EUCL charges applies to
CFC's payphones as well as to LEC-owned payphones. Fur-
thermore, the record reflects that CFC's payphones are
indistinguishable from LEC's payphones from a consumer's
point of view; at oral argument, counsel for the Commission
conceded that a consumer making a call from a bank of
payphones would have no idea whether that phone was inde-
pendently owned or owned by an LEC. And the Commission
does not dispute that CFC's payphones are indeed held out
for use by the general public. See Order at 9780, p 21 ("[W]e
recognize that it is not CFC's intent to provide private service
via its payphones.").

We also hold that the Commission erred when it focused on
how CFC's payphones could be used, as opposed to how they
were used. As we explained above, this test led the Commis-
sion to conclude that CFC's payphones were "semi-public"
because they were connected to ordinary business subscriber
lines, as opposed to special coin lines. The Access Charge
Reconsideration decision, which introduced the distinction
between "public" and "semi-public" for purposes of the
EUCL charge, does not mention this "capability of use"
distinction, and further suggests that the key distinction was
meant to be actual use. See Access Charge Reconsideration
at 704 n.40 ("[A] pay telephone is used to provide semipublic
telephone service when there is a combination of general
public and specific customer need for the service, such as at a
gasoline station or pizza parlor.") (emphasis added). Further,
since the record does not indicate that the loop costs of LEC-
owned payphones are significantly different from those of
CFC's payphones--and indeed, under the current regime,
both types of payphones are subject to the EUCL charge--
the technical distinction drawn by the Commission here has
no apparent relevance to the access charge at issue.

D.

We note that the Communications Act provides that "[i]t
shall be unlawful for any common carrier to make any unjust

or unreasonable discrimination in charges ... for ... like
communication service." 47 U.S.C. s 202(a). To determine if
a carrier is discriminating in violation of this provision, the
Commission asks: (1) whether the services are "like"; (2) if
they are, whether there is a price difference between them;
and (3) if there is, whether that difference is reasonable.
Competitive Telecommunications Ass'n v. F.C.C., 998 F.2d
1058, 1061 (D.C. Cir. 1993). To determine if services are
"like" under this provision, the Commission must "look to the
nature of the services offered and ascertain whether custom-
ers view them as performing the same functions." Id. (inter-
nal quotations and citation omitted).

Here, the Commission never explicitly considered whether
CFC's payphones and LEC-owned payphones provided "like"
services. Rather, it found that the LECs which had assessed
EUCL charges against CFC had not discriminated in viola-
tion of Section 202(a) because the LECs had followed FCC
rules when assessing these charges. Order at 9780, p 23.
Given our conclusion that the Commission misinterpreted its
rules, it appears that the Commission's Order may have
compelled LECs to discriminate in violation of Section 202(a):
consumers view CFC's payphones and LEC-owned pay-
phones as performing the same functions, and only LEC-
owned payphones are exempted from the EUCL charges.
Because we vacate the Commission's Order and remand for
further proceedings, however, we need not resolve whether
the Commission's interpretation compelled LECs to discrimi-
nate under Section 202(a), or the precise consequences if it
did.

Joined by Intervenor LECs Century Telephone of Wiscon-
sin, North-West Telephone Company and GTE North Incor-
porated, the Commission argues that CFC may not recover
the EUCL charges it has already paid because the LECs
which collected those charges did so in compliance with
Commission rules. Although we recognize the importance of
this issue, we need not resolve it here in light of our holding
that the Commission misinterpreted its own rules.

III. Conclusion

The Commission has articulated a difference between
CFC's payphones and LEC-owned payphones: CFC's
"smart" payphones are connected to ordinary business sub-
scriber lines and LEC-owned "dumb" payphones are connect-
ed to special coin lines. It has not, however, sufficiently
explained why this difference justifies its decision to assess
EUCL charges on the "smart" payphones but not the "dumb"
payphones. For this reason, and because the Commission's
interpretation of its rules was clearly erroneous, we vacate
the Commission's Order and remand for further proceedings
consistent with this opinion.
