                       October 23, 2001
          BOUDIN,     Chief        Judge.         The     Federal     Aviation

Administration     ("FAA")    authorized      Shuttle      America    Airlines

("Shuttle America") to provide scheduled passenger service to

New York's LaGuardia Airport ("LaGuardia") from Hanscom Field

("Hanscom"), a general aviation airport that lies 15 miles

northwest of Boston abutting the towns of Bedford, Concord,

Lexington, and Lincoln.           The petitioners--two preservationist

organizations,     three     of    the     four   towns    (Bedford    is    an

intervenor), and stewards of several nearby historic sites--seek

review of the FAA decision on the ground that the agency did not

adequately consider the adverse effect of the additional Shuttle

America flights on historic and natural resources near Hanscom.

          Hanscom has been a major aviation facility since 1940,

when the Commonwealth of Massachusetts first acquired the site

to   accommodate    the    U.S.     Army    Air   Corps.      In     1973   the

Massachusetts Port Authority ("MassPort") converted a portion of

the site into a general aviation facility serving corporate

aviation, flight schools, air charter operations, light cargo,

and private business and recreational flights.                (The U.S. Air

Force uses the remainder as Hanscom Air Force Base.)                  In 1995,

there were about 95,000 general aviation and military flights

(defined as a departure and an arrival) at Hanscom.




                                     -3-
           In recent years, MassPort and the FAA have expanded

commercial    passenger     service    at    Hanscom,    seeking    to    lessen

congestion at Boston's Logan International Airport.                These steps

have concerned community groups who fear that the increased

noise, air pollution, and surface traffic from the additional

flights    will    harm   the   natural     and   historic   resources      near

Hanscom.    These sites include Minute Man National Historic Park,

Walden Pond, and the homes of eminent American authors such as

Ralph Waldo Emerson and Louisa May Alcott.              The main access road

to Hanscom is a part of Route 2A, which runs through the heart

of Minute Man National Park.

           In July 1999, MassPort backed a plan to let Shuttle

America--a    commuter     airline    then    operating      out   of    several

airports on the East Coast--provide scheduled passenger service

at Hanscom.       To this end, Shuttle America asked the FAA to add

Hanscom to the list of airport destinations in its operating

specifications.       MassPort asked the FAA to upgrade Hanscom's

operating certificate to a "full Part 139 certificate," which

allows use of planes with greater than 30 seats.               See generally

14 C.F.R. Part 139 (2000).

           The FAA granted both requests in September 1999, and

Shuttle America immediately commenced passenger service out of

Hanscom, with four daily round-trip flights.             The FAA determined


                                      -4-
that it did not need to perform an environmental analysis for

the two approvals because they were categorically excluded from

review under the National Environmental Policy Act of 1969

("NEPA"), 42 U.S.C. § 4321 et seq. (1994).         It also concluded

that the categorical exclusion under NEPA obviated the need for

consultation   under   Section   106   of    the   National   Historic

Preservation Act of 1966 ("NHPA"), 16 U.S.C. § 470f (1994).

         The Advisory Council on Historic Preservation, which

is authorized to enforce NHPA, see 16 U.S.C. § 470s, questioned

the FAA's reading of NHPA, and petitioner Save Our Heritage

unsuccessfully sought reconsideration and rehearing of both the

Part 139 certification and the addition of Hanscom to Shuttle

America's operating specifications.         However, no party sought

timely judicial review of either of the FAA's decisions; such

review is now time-barred.   49 U.S.C. § 46110(a) (1994).1

         In May 2000, Shuttle America applied for the operating

specifications amendment at issue in this case--an amendment to

add LaGuardia to its list of approved airport destinations.         It

proposed to make seven round-trip flights between Hanscom and

LaGuardia, with the possibility of eventually expanding the

service to ten flights a day.            The FAA expressed doubt that NHPA

consultation    was    required,         but     in    light   of   the   Advisory

Council's earlier concerns, it decided it would be "prudent" to

consult     provisionally         with     the        Massachusetts     Historical

Commission, which the Commonwealth had designated as its NHPA

consulting agency.         After conducting an environmental analysis,

the   FAA   proposed   a    finding      that    the     additional   flights     to

LaGuardia would have no potential adverse effect on historic

properties.

            Petitioners Save Our Heritage and the Hanscom-area

towns sent the FAA detailed criticisms of its proposed finding,

and the Massachusetts Historical Commission also refused to

concur.       After    providing         additional       documentation     in    an

unsuccessful    effort       to    persuade       the     Commission,     the    FAA

terminated the consultation and, on October 27, 2000, issued the

amendment ("the LaGuardia amendment").                    Shuttle America began

commercial service from Hanscom to LaGuardia with five round-

trip flights per day, later reaching a peak of seven daily

round-trip flights in January 2001.2




      2
     Since that time, Shuttle America has entered into Chapter
11 reorganization proceedings, but it continues to maintain one
LaGuardia flight daily and has stated that it hopes eventually
to reinstate its previous level of service.

                                         -6-
             On direct review, 49 U.S.C. § 46110(a), petitioners now

ask us to set aside and enjoin the LaGuardia amendment on the

grounds the FAA decision violated NEPA, NHPA, and Section 4(f)

of the Department of Transportation Act of 1966, 49 U.S.C. §

303(c)    (1994)   (originally   codified   at    49   U.S.C.   §   1653(f)

(1970)).     The statutory requirements are described below.            The

gist of the FAA's position is that its "effects" determination--

that the addition of seven to ten flights a day would have no

significant environmental impact--exempted the amendment from or

otherwise satisfied these requirements.

             At the threshold, the FAA and supporting intervenors

raise two objections to our consideration of the case.                  The

first is that the petitioners lack Article III standing, and the

second is that the petitions are effectively out-of-time attacks

on   prior    agency   orders.    Because   the    first   challenge     is

constitutional, we start with it.

             The basic requirements for Article III standing are

that the petitioner is someone who has suffered or is threatened

by injury in fact to a cognizable interest, that the injury is

causally connected to the defendant's action, and that it can be

abated by a remedy the court is competent to give. 3                   What

constitutes a "cognizable interest" can present vexing problems,

see Chemerinsky, Federal Jurisdiction § 2.3, at 68-74 (3d ed.

1999), but here the FAA and supporting intervenors concede that

aesthetic and environmental injury are cognizable, see Sierra

Club v. Morton, 405 U.S. 727, 734 (1972).

           Rather, the objections to standing are threefold.                The

first, and least persuasive, is the suggestion that even if some

individuals    or   organizations     are   adversely     affected     by   the

increased flights, none of the petitioners or identified members

of petitioner organizations have shown that they are among those

injured.      Admittedly,   a   specified     petitioner    or   identified

member must be within the affected group.               See Friends of the

Earth, Inc. v. Laidlaw Envt'l Servs., Inc., 528 U.S. 167, 181-84

(2000).

           Here, the petitioners comprise nonprofit environmental

or preservationist associations such as Save Our Heritage; the

towns located near Hanscom; and at least two petitioners that

own nearby historic sites:      the Walden Woods Project, which owns

part of the Walden Woods site and operates a Thoreau research

and   educational   facility    on   it;    and   the   Louisa   May   Alcott

Memorial Association, which manages the writer's home.                  It is

sufficient for the case to proceed if at least one petitioner

                                     -8-
has standing, Wash. Legal Found. v. Mass. Bar Found., 993 F.2d

962, 971-72 (1st Cir. 1993).

          There is little reason to doubt that the two nonprofit

landowners (Walden Woods Project and the Alcott Association)

would be affected by both noise and air pollution, given their

function and proximity to Hanscom; and it is likely, although

unnecessary to decide, that the three towns themselves would

have a direct interest, e.g., in traffic congestion.4             We need

not resolve whether the petitioner associations have established

standing based on the rather sparse allegations of injury to the

interests of their individual members.        See Int'l Union, United

Auto., Aero. & Agric. Implement Workers of Am. v. Brock, 477

U.S. 274, 281-82 (1986).

          Next,   the    FAA   says   that   there   is    no   actual   or

threatened adverse effect on any petitioner because, according

to the FAA's findings, the small number of additional flights

will have no significant environmental impact.            At first blush,

this appears to be a question of the merits rather than one of

standing; the petitioners certainly allege substantial effects

and   challenge   both   the    FAA's   contrary     findings    and     the

procedures used to reach them.


      4
     Lujan v. Defenders of Wildlife, 504 U.S. 555, 572 n.7
(1992); Douglas County v. Babbitt, 48 F.3d 1495, 1501 (9th Cir.
1995), cert. denied, 516 U.S. 1042 (1996).

                                  -9-
         We need not rule out the possibility of cases where the

claim of impact is so specious or patently implausible that a

threshold standing objection might be appropriate.     See, e.g.,

Town of Norwood, 202 F.3d at 406; Florida Audubon Soc'y v.

Bentsen, 94 F.3d 658, 669 (D.C. Cir. 1996).    But beyond that, we

think that the likelihood and extent of impact are properly

addressed in connection with the merits and issues of harmless

error.   Breyer & Stewart,   Administrative Law and Regulatory

Policy 1107 (2d ed. 1985); cf. Bell v. Hood, 327 U.S. 678, 681-

84 (1946).    A reasonable claim of minimal impact is enough for

standing even though it may not trigger agency obligations.

         Third, the FAA points out that the order here under

review did not increase the number of flights that Shuttle

America is authorized to operate at Hanscom.   Given prior orders

that are now beyond review, Shuttle America was and is entitled

to fly an unlimited number of flights to its other, already-

approved airports regardless of the outcome of this case.   Thus,

says the FAA, the order permitting flights to LaGuardia cannot

be the cause of the alleged injury to petitioners, because it

could fly the same number of flights even if the order were

overturned.

         If the same number of flights carrying the same number

of passengers would be flown regardless of the present order,


                               -10-
the order would hardly be the but-for cause of any impact due to

more flights or ground traffic.             But as a matter of common

sense, Shuttle America likely sought authorization for LaGuardia

because it would generate some additional traffic over and above

its existing demand.      Shuttle America has not shown or offered

to show that the number of flights and the amount of car traffic

would be identical even without the authorization.            Petitioners

asserting standing are not required to negate every possibility

that   the    outcome   might   be   the    same   under   highly   unusual

circumstances.

             The FAA makes a separate and quite different threshold

objection.      It says that petitioners are making out-of-time

attacks on prior orders.        It points out that the statute imposes

a 60-day limit on direct review, 49 U.S.C. § 46110(a), and, no

petition for review having been filed within that time, it

argues that it is not open to petitioners now to challenge the

orders entered in September 1999 allowing Shuttle America to

operate from Hanscom and Hanscom to handle commercial flights

using larger planes.

             No doubt much of the impact on nearby natural and

historic sites, assuming the allegations are true, stems from

these earlier orders and not from the authorization to add a

limited number of flights to LaGuardia.                Nevertheless, the


                                     -11-
petitioners are entitled to claim that an additional impact will

be felt from the now-authorized LaGuardia flights, over and

above the effects of the prior orders.                    Whether or not the

plausible    added      effects    are     so   slight    as    to     justify      the

shortcuts    taken      by   the   FAA    is    a   merits     issue    yet    to   be

addressed; but it does not make an attack on this alleged

incremental impact an attack on the wrong order.

            Only   to    the   extent     that      petitioners      are   actually

seeking redress from the effects of the present orders are their

petitions timely, and this limitation must be borne in mind in

considering the arguments.           Admittedly, there is some language

in the briefs that appears to attack the earlier orders because

of alleged infirmities in its findings or procedures.                         But the

possibility that some of the petitioners' arguments are time-

barred does not defeat those actually directed to the more

recent order.

            This brings us to the merits.             Although the claims can

be segmented in several ways, the underlying issues basically

reduce themselves to two: whether the FAA erred substantively in

concluding that the additional flights--up to ten new round

trips a day--would have a de minimis environmental impact and

whether, regardless of impact, the FAA erred procedurally in

failing to consult further with governmental agencies concerned


                                         -12-
with historic preservation.             We begin with the "substantive"

issue which arises, in slightly different frameworks, under

three different statutes.

            The most familiar is NEPA, which requires agencies to

develop a detailed environmental impact statement (an "EIS")

before     undertaking      "major      Federal    actions       significantly

affecting the quality of the human environment."                  42 U.S.C. §

4332(2)(C).      The NEPA regulations permit agencies to conduct a

less demanding "environmental assessment" to determine whether

an   EIS   is   required;    if   not,    the   agency    must    explain   its

determination in a "finding of no significant impact."                      40

C.F.R. §§ 1501.4 (2000).

            In a regulation whose validity is not in dispute, the

FAA effectively concedes that the LaGuardia amendment qualifies

as a major federal action.              Dep't of Transp., Fed. Aviation

Admin. Order 1050.1D, "Policies and Procedures for Considering

Environmental Impacts," App. 4, ¶ 3(e).5            However, a categorical

exclusion excuses the FAA from preparing either an EIS or an

environmental     assessment      for    "operating      specifications     and

amendments      thereto   which    do    not    significantly      change   the


      5
      FAA Order 1050.1D, which was in effect at the time of the
LaGuardia amendment, is the FAA's formal rule for implementing
all three statutes implicated in this case. 49 Fed. Reg. 28,501
(July 12, 1984).    A proposed revision to the order is not
relevant here. See 64 Fed. Reg. 55,526 (Oct. 19, 1999).

                                     -13-
operating environment of the airport."              FAA 1050.1D, App. 4, ¶

4(h).

              This exclusion is itself qualified by an "extraordinary

circumstances"          provision      which     requires     at        least   an

environmental assessment for an otherwise excluded action if the

action is, inter alia, "likely to have an effect that is not

minimal on properties protected under Section 106 of [NHPA] or

Section 4(f) [of the Transportation Act of 1966]," or "likely to

be highly controversial on environmental grounds."                      FAA Order

1050.1D, ¶ 32.        Petitioners rely on both of these exceptions and

argue that the additional flights have more than minimal effects

and were highly controversial.

              NHPA and Section 4(f) impose different requirements

than NEPA, in the service of somewhat more focused interests;

but     the    requirements      of    concern   here--with       one    possible

qualification regarding an obligation to consult--both turn (as

with    NEPA)    on   whether    the   agency    action   poses    a    plausible

environmental threat.           A brief description of the two statutes

makes this clear.

              NHPA, heavily relied on by petitioners, is designed to

protect       certain    "historic     properties,"       which    indisputably

include sites near Hanscom.            Section 106 of the statute requires

that prior to a proposed federal "undertaking," the agency must


                                        -14-
"take into account the effect" on such properties and allow the

Advisory    Council     on     Historic        Preservation            a     "reasonable

opportunity to comment."                16 U.S.C. § 470f.                  The act thus

imposes    both   a   substantive        obligation          to    weigh     effects     in

deciding    whether     to     authorize        the        federal     action     and     a

procedural obligation to consult.               See generally 36 C.F.R. Part

800 (2000).

            The   grant      of     a    permit       such        as   the     LaGuardia

authorization can certainly qualify as an undertaking.                                   16

U.S.C. § 470w(7)(C); 36 C.F.R. § 800.16(y) (2000);                             see also

Sugarloaf Citizens Ass'n v. Fed. Energy Reg. Comm'n, 959 F.2d

508, 515 (4th Cir. 1992).               But even if the approval of the

LaGuardia     flights     is      assumed      to     be    an     undertaking,         the

substantive obligation to "take into account the effect" of the

flights on historic properties is beside the point if there is

no   potential    adverse      effect.      See       36    C.F.R.     §     800.3(a)(1)

(2000).    To that extent, the question under NEPA and under NHPA

is the same: whether the FAA erred in finding that any impact of

the newly authorized flights on the surrounding area was                                 de

minimis.

            The last of the three statutes--Section 4(f) of the

Department of Transportation Act--is even more stringent where

it applies.       It protects certain public parks and historic


                                        -15-
sites, again indisputably including some near Hanscom, from any

"transportation program or project" requiring the "use" of such

park or land, unless certain quite restrictive tests have been

met.     To proceed in the teeth of such a "use," the agency must

find that there is no feasible alternative to using that land

and that the program or project includes all possible planning

to minimize harm.       49 U.S.C. § 303(c).

            At first blush, one might think that Section 4(f) could

have    nothing    to   do   with    authorizing      new    flights      from   an

existing, physically unaltered airport; but the statute has been

read to apply not only to a physical use or occupancy of

protected parks or land but also to activities that will have a

serious indirect impact on the protected park or land--a so-

called    "constructive      use."     23    C.F.R.    §    771.135(p)(1)(iii)

(2000); Morongo Band of Mission Indians v. Fed. Aviation Admin.,

161 F.3d 569, 583 (9th Cir. 1998).                 Once again, the FAA's

finding that the LaGuardia flights would have only a de minimis

effect would avoid the statute if the finding were to be upheld.

Adler v. Lewis, 675 F.2d 1085, 1092 (9th Cir. 1982).

            What, then, underpins the FAA's finding of de minimis

impact in this case?         The starting point is that independent of

the    LaGuardia   flights,     Hanscom      handled       just   under   100,000

flights in 1999, and the disputed LaGuardia flights would add,


                                      -16-
at a maximum, ten more flights per day.              The more realistic

estimate of seven flights, according to the FAA, would produce

an annual increase in Hanscom flights of about 2.5 percent--a

number that absent special circumstances would approach the

trivial.

           This figure might at first appear to understate the

potential environmental effect because most existing Hanscom

flights are private aircraft, which are somewhat smaller and

carry   fewer   passengers    than    even   the   modest      50   passenger

turboprop planes used by Shuttle America.            On the other hand,

some of the resulting ground traffic occurs in non-peak periods

where   existing   levels    are   light,    and   the   new    flights   use

turboprop aircraft considerably quieter than the corporate jets

and other civilian aircraft currently using the airport.                Thus,

certain effects of the additional flights may be less than the

already small percentage increase in the number of flights.

           But we need not rely on such inferences because here

the FAA directly studied the three types of potential effects

from the additional flights: noise, fuel emissions, and surface

traffic from passenger travel to and from the airport.                     As

background for considering the effects, the FAA extrapolated

from MassPort's 1995 Generic Environmental Impact Report ("the

GEIR"),    actually   completed      in   1997,    which    projected     and


                                   -17-
extensively assessed the noise, emissions, and traffic effects

of future Hanscom operations under zero, modest, and robust

growth scenarios for commercial aviation.                    It also relied on a

surface traffic study performed in 2000 for the adjacent Hanscom

Air Force Base.

              The FAA summarized its findings in two letters (on

September 15, 2000 and October 6, 2000) to the Massachusetts

Historical Commission.            The FAA first compared the actual number

of flights in 1999 (prior to the LaGuardia authorization) with

the GEIR's 1999 projections under the modest growth scenario,

and    found       that    the     GEIR's     forecast       was     nearly    exact

(approximately          99,000    flights).         This    both    confirmed    the

accuracy      of    the    GEIR    and,     since    the     GEIR    indicated    no

significant        environmental      concerns      under    the    modest    growth

scenario, showed that pre-amendment baseline conditions were

acceptable.

              The FAA then conducted its own studies, which found

that    the   additional        LaGuardia    flights       would    not   exacerbate

environmental conditions.            As to noise, the FAA found that the

additional flights would have a 1 percent or less increase in

the    65   DNL    dB   noise    contour,    which    indicates       noise   levels

compatible with all land uses, see 14 C.F.R. Part 150, App. A,

Tbl. 1 (2001), under a test in which a 17 percent increase is


                                          -18-
deemed significant.     It also found that the 65 DNL dB noise

contour would continue to remain "almost completely on airport

property" and that most of Minute Man National Park and Walden

Woods would fall outside the 55 DNL dB line.6     It thus concluded

that the area around Hanscom "should not experience appreciable

increases in aircraft noise or overflights" as a result of the

added air traffic.

          For air quality effects, the FAA used a model that took

account of emissions both from aircraft (accounting for factors

such as equipment type and including take-off, taxi, and idling

time) and surface vehicles (both passenger traffic and ground

support   equipment).   The   FAA   concluded   that   the   potential

emissions associated with the LaGuardia flights were "below de

minimis levels" as to both of the two critical ozone-producing

pollutants and that the new flights would not undercut the

state's implementation plan for air quality.

          As for surface traffic, the FAA found that none of the

flights would affect peak morning traffic and only one would

affect peak evening traffic.    Estimating that each flight would

generate 70 additional vehicle trips, it concluded that, at



    6These noise contour lines demarcate the land area enclosed
within a particular level of noise, measured in "day-night
average sound level" ("DNL") units, which represent the average
decibel level at a particular location over a 24-hour period.

                               -19-
worst, the peak evening flight would increase traffic at several

intersections on Route 2A by only about 2.65 percent, which the

FAA deemed minimal and within the GEIR projection already found

to be tolerable.        As for noise increase, it found that the

increased traffic volume would raise the peak level by less than

0.3 dB, "which is not a perceptible increase."            See 23 C.F.R. §

771.135(p)(5)(iii) (2001).

            Remarkably, in their lengthy submissions, petitioners

make no direct attack on the aircraft noise or air pollution

conclusions.      Petitioners say only that any reliance on the GEIR

was "inappropriate" because it was prepared for "unrelated"

operations and is out of date.          But in fact, the FAA verified

the GEIR's accuracy by finding that the actual growth at Hanscom

as   of   1999    coincided   almost   exactly   with   the   GEIR    "modest

growth" scenario whose environmental effects had already been

considered.

            The FAA's surface traffic analysis gets more attention,

but even here their discussion is limited to a few pages and is

confined to three brands of criticism: highly general claims

that the agency's analysis is inadequate (e.g., that the FAA

should     have     discussed    non-peak   hour    traffic      or    other

intersections); criticisms of the agency's factual assumptions

(e.g., that the FAA underestimated the number of vehicle trips


                                   -20-
that each passenger would take); or abstract statements of

disagreement by other entities (e.g., claims by the National

Park   Service        that   increased     traffic       would   have   "serious

detrimental impacts").

            Under settled doctrine, the FAA's factual findings are

conclusive if supported by substantial evidence, 49 U.S.C. §

46110(c), and its reasoning is tested for reasonableness under

an arbitrary and capricious standard.                    5 U.S.C. § 706(2)(A);

Penobscot Air Servs., Ltd. v. Fed. Aviation Admin., 164 F.3d

713, 718-20 (1st Cir. 1999).              Further, it is up to those who

assail its findings or reasoning to identify the defects in

evidence and the faults in reasoning.               Lomak Petroleum, Inc. v.

Fed. Energy Reg. Comm'n, 206 F.3d 1193, 1198 (D.C. Cir. 2000).



            Where the agency is dealing with a very complicated and

technical subject, this takes a lot of work by lawyers in

culling   the    record      and   organizing      the    information    for   the

reviewing court, but it can be done.                     Here, the FAA's final

assessment--that a tiny percentage increase in flights would

have a    de minimis effect--is presumptively inviting but, in

principle,      can    be    overcome    by    a   sustained     and    organized

rebuttal.       Nothing offered by petitioners approaches such an

effort.   Gauzy generalizations and pin-prick criticisms, in the


                                        -21-
face of specific findings and a plausible result, are not even

a start at a serious assault.

            There is one obvious concern, and it is not about the

impact of    this extremely modest increase in Shuttle America

flights.    Conceivably, Shuttle America or another airline could

appear with a succession of new-destination proposals, each

modest in size and in impact; and yet the cumulative effect of

the FAA approvals could be major even though no one approval was

significant in itself.        Either a clear plan for such successive

steps or proof that such a succession was foreseeable could

conceivably    require   an   overall     prospective   assessment.   40

C.F.R. §§ 1508.4, 1508.27(b)(7) (2000).

            But we are not faced with any such developed claim in

this case, nor do the known facts suggest any such thing.             At

the time of Shuttle America's application, commercial service at

Hanscom had been a repeated failure, and there was no reason to

believe, at that point, that demand would dramatically increase.

Now, Shuttle America has reduced its operations and is under the

protection of the bankruptcy court.         If Shuttle America or other

airlines undertake a series of proposed expansions, it will be

time enough to consider whether new and projected activities

need to be considered together.




                                   -22-
             Petitioners         say    that     even   if    the    minimal      effects

finding stands, the FAA's own regulations still required at

least   an    environmental            assessment       under    NEPA       because     the

proposed     action       was    "highly    controversial           on     environmental

grounds."         FAA Order 1050.1D ¶ 32(b).              The FAA's regulations,

read literally, indicate that this test is met if the "action"

in question is "opposed on environmental grounds by a Federal,

State, or local government agency or by a substantial number of

the persons affected."             FAA Order 1050.1D, ¶ 17.                 Although the

federal and state agencies did not formally oppose the LaGuardia

flights    (instead        simply       asking    for    more    study),         the   four

adjoining towns flatly opposed the new flights.

             Citing a number of cases, the FAA argues that whether

a project is environmentally controversial does not depend on

whether      vocal       opponents      exist     but    on     whether       reasonable

disagreement         exists      over     the     project's         risk    of    causing

environmental harm.             See, e.g., Found. for N. Am. Wild Sheep v.

U.S. Dep't of Agric., 681 F.2d 1172, 1182 (9th Cir. 1982).

Otherwise, says the FAA, projects could be bogged down by a

"heckler's veto" despite the lack of a genuine environmental

threat.      The FAA says that its own assessment here that the

project      is    not    objectively          controversial         is    entitled      to

deference.


                                           -23-
            The FAA's approach certainly makes sense on policy

grounds, but it is in some tension with the wording of its own

regulation, which seems to make official opposition to the

proposed "action" the trigger.            By contrast, the decisions on

which the FAA relies interpret "controversial" as used in other

regulations, where the term modifies "effects"--phrasing more

helpful to the FAA's reading.            See, e.g., id. (interpreting 40

C.F.R. § 1508.27(b)(4)).

            We need not decide whether the latitude allowed to the

agency in interpreting its own regulations, see Thomas Jefferson

Univ. v.      Shalala, 512 U.S. 504, 512 (1994), stretches to a

reading that may make policy sense but appears at odds with the

language.      (Certainly the FAA might wish expressly to clarify

its language for future cases.)           Rather, we think that even if

the "controversial" action regulation is read in petitioners'

favor,   it    makes   no   sense   to    remand   for   an   environmental

assessment where, as here, the FAA has already made a reasoned

finding that the environmental effects are de minimis.                In a

nutshell, the failure to make a more formal assessment was

harmless error.

            The doctrine of harmless error is as much a part of

judicial review of administrative action as of appellate review

of trial court judgments.       Indeed, the Administrative Procedure


                                    -24-
Act, 5 U.S.C. § 706, says that in reviewing agency action, the

court "shall" take due account of "the rule of prejudicial

error," i.e., whether the error caused actual prejudice.                             And

while     many    of   the      decisions     involve        harmless    substantive

mistakes, no less an authority than Judge Friendly has applied

the harmless error rule to procedural error, as has the circuit

that most often reviews agency action.7

            Obviously, a court must be cautious in assuming that

the   result     would     be    the   same     if    an   error,     procedural     or

substantive, had not occurred, and there may be some errors too

fundamental to disregard.              But even in criminal cases involving

constitutional error, courts may ordinarily conclude that an

admitted    and    fully     preserved        error    was    "harmless    beyond      a

reasonable       doubt."     Chapman     v.   California,       386     U.S.   18,   24

(1967).     Agency missteps too may be disregarded where it is

clear that a remand "would accomplish nothing beyond further

expense and delay."          Kerner, 340 F.2d at 740.

          We will assume that an environmental assessment and

finding of no significant impact might look somewhat different

in form and follow somewhat more complicated procedures than the

study and findings by the FAA in this case.                 See generally 40

C.F.R. §§ 1501.4, 1508.9, 1508.13 (2000).             But this case does

not   involve     a     simple   refusal   to     study      environmentally

problematic consequences.          On the contrary, even though only

seven to ten flights a day are realistically at issue, the FAA

examined each of the three principal possible negative effects

and found each to be de minimis, and petitioners have provided

no basis for serious doubt about those findings.

          Under         these    circumstances,       the     presence    of

"controversy" is beside the point.         Ultimately, the entire NEPA

process is designed to make certain that significant negative

effects are taken into account.        See Robertson v. Methow Valley

Citizens Council, 490 U.S. 332, 348-50 (1989).               Remanding for a

differently     named    assessment,   where    the   project's     negative

consequences have already been analyzed and found to be absent

and the findings have been disclosed to interested parties, is

a waste of time.           If there was error in denominating the

assessment, it was patently harmless.

          The same is true of petitioners' argument that the FAA

committed a procedural error by failing to consult adequately


                                    -26-
with the Massachusetts Historical Commission.          As already noted,

NHPA imposes an obligation not only to take account of adverse

effects of an "undertaking" on historic properties but also to

permit the federal Advisory Council a "reasonable opportunity to

comment."      This     might   sound    like   an    obligation   easily

discharged, but that is far from the case.

            On the contrary, the Advisory Council's regulations,

once they are triggered, impose a complex consultative process.

See generally 36 C.F.R Part 800 (2000).              Although the choice

whether to approve the undertaking ultimately remains with the

agency, it must consult with the state historic preservation

officer--here,    the    Massachusetts    Historical     Commission--and

other "consulting parties" about adverse effects on historic

properties, document any no- effect finding, and submit the

effects issue to binding review by the Advisory Council if the

state officer and the federal agency disagree.             36 C.F.R. §§

800.4, 800.5 (2000).      If adverse effects are established, even

more complex steps are entailed.8


    8Assuming an adverse effect is found, the agency must
consult with the state officer and other consulting parties to
develop and evaluate mitigation measures.   36 C.F.R. § 800.6
(2000). The process is then completed either by a "memorandum
of agreement" between the agency and the consulting parties,
which then governs the federal undertaking, 16 U.S.C. § 470h-
2(l), or by termination of the consultation by the agency
followed by the issuance of formal comments by the Advisory
Council, 36 C.F.R. § 800.7 (2000).

                                  -27-
             Understandably, agencies are loath to submit to this

cumbersome process, and the NHPA regulation in effect at the

time the FAA acted contained a categorical exemption from the

consultation process where "the undertaking does not have the

potential to cause effects on historic properties."                       36 C.F.R.

§ 800.3(a)(1) (2000).             No consultation was required for this

decision.     64 Fed. Reg. 27,063 (1999).                 The FAA found that the

LaGuardia     flights       had    no    such    potential       and,   after    some

consultation with the state officer, discontinued the process,

relying on the regulation's exemption.

             As already explained, petitioners make nothing close

to a colorable attack on the FAA's finding that the ten or fewer

LaGuardia flights in question would not adversely affect nearby

historic     sites     in     any       substantial       way.      Nevertheless,

petitioners        argue    that    under       section     800.3(a)(1)     of     the

regulations, it is enough to trigger the consultation process

that   the   FAA    action    is    a    "type    of   activity"--a       change    in

operating specifications--that in some other case could have a

potential adverse affect.

             The    main    support      for    this   reading    comes   from     the

language in the overarching paragraph (section 800.3(a)) and the

Advisory Council's amendment of section 800.3(a)(1) following

the FAA decision in this case, 65 Fed. Reg. 77,698, 77,726 (Dec.


                                         -28-
12, 2000), both of which employ the "type of activity" language.9

The Advisory Council claims that the amendment reflects what the

regulation always meant.        Although it is not the most natural

reading of the original regulation, a definitive judgment as to

meaning   would   have   to   allow   some   deference   to   an   agency's

clarification.    See Thomas Jefferson Univ. 512 U.S. at 512.

           At the same time, the current regulation could make the

exemption useless to the FAA--at least, if the FAA continues to

view "operating specifications" as the category to which "type"

refers.   One could easily think of          some change in operating

specifications--as to equipment, frequency or other variables--

that could have a significant environmental effect.            Of course,

the current regulation does not define the notion of a "type";

conceivably, the FAA could still distinguish among "types" of



     9
     Prior to the amendment, 36 C.F.R. § 800.3(a) (2000) read as
follows:
         (a) The Agency Official shall determine
         whether the proposed Federal action is an
         undertaking . . . and, if so, whether it is
         a type of activity that has the potential to
         cause effects on historic properties. . . .
         (1) If the undertaking does not have the
         potential to cause effects on historic
         properties, the Agency Official has no
         further obligations under section 106.

The amendment changed section 800.3(a)(1) to read "If the
undertaking is a type of activity that does not have the
potential to cause effects on historic properties. . . ." 65
Fed. Reg. 77,698, 77,728 (Dec. 12, 2000).

                                  -29-
amendments so as to preserve some role for the categorical

exception.

          We need not resolve any of these questions.                   The

consultative process under NHPA, like the process of creating an

EIS or environmental assessment under NEPA, is intended in the

end to identify and measure the adverse effects of a proposed

action on a protected interest (historic properties for NHPA,

the   environment   for   NEPA)   so     that   those   effects   can    be

considered by the responsible agency.

          Here, the FAA did make specific findings that the

effects on the environment and on historic properties from ten

or so daily flights, against the backdrop of nearly 100,000

flights a year, would be de minimis.            If the question were at

all close and if plausible doubts had been raised, requiring a

more elaborate assessment with more extensive consultation might

serve some useful purpose.        But neither is the case and, in

these circumstances, the error (if there was one) is harmless.



          The petition for review is denied.
