Before JOLLY and DUHÉ, Circuit Judges, and PARKER*, District Judge.

      *
       Chief Judge of the Eastern District of Texas, sitting by
designation.
E. GRADY JOLLY, Circuit Judge:

     The Environmental Protection Agency (EPA) seeks to recover its

response costs under the Comprehensive Environmental Response,

Compensation and Liability Act (CERCLA) because of a discharge of

chromium waste that contaminated a local water supply.                  Sequa

Corporation appeals from the imposition of joint and several

liability, challenges the EPA's decision to provide an alternate

water supply system to the area in which the groundwater was

contaminated   by    the   chromium       discharge,   and   contests     the

calculation of prejudgment interest and the application of the

proceeds of the EPA's settlement with its co-defendants.                   We

REVERSE the portion of the judgment imposing joint and several

liability, and REMAND for further proceedings.            Our review of the

administrative record has convinced us that the EPA's decision to

provide an alternate water supply was arbitrary and capricious;

accordingly,   we   REVERSE   the   portion    of   the   district   court's

judgment allowing the EPA to recover the costs of designing and

constructing that system, and REMAND for deletion of those amounts

and recalculating prejudgment interest.1

                                      I

     In 1978, a citizen in the Odessa, Texas area complained about

discolored drinking water. The Texas Water Commission conducted an

investigation. It ultimately focused on a chrome-plating shop that

     1
      Sequa also appealed an award of sanctions against it, but
advised us after oral argument that the matter had been resolved.




                                    -2-
was operated successively from 1971 through 1977 by John Leigh,

Western Pollution Control Corporation (hereinafter referred to as

Bell), and Woolley Tool Division of Chromalloy American Corporation

(which later merged with Sequa), at 4318 Brazos Street, just

outside the city limits of Odessa.       The investigation showed that

during the chrome-plating process, finished parts were rinsed, and

the rinse water was pumped out of the building onto the ground.

     In 1984, the EPA designated a 24-block area north of the

Brazos Street facility as a Superfund site--"Odessa Chromium I."

It authorized a response action pursuant to its authority under

CERCLA § 104, 42 U.S.C. § 9604, and entered into a cooperative

agreement with the State of Texas.         The State was to perform a

remedial investigation, feasibility study, and remedial design work

for the site, with the EPA reimbursing the State for ninety percent

of the costs. The remedial investigation revealed that the Trinity

Aquifer, the only source of groundwater in the area, contained

elevated concentrations of chromium.2

     A "focused" feasibility study (FFS) was undertaken to evaluate

the need to provide an alternative water supply pending completion

of   the     remaining   portion   of    the   feasibility   study   and

implementation of final remedial action.3       The FFS concluded that

     2
     Chromium is a "hazardous substance" as defined in CERCLA.        42
U.S.C. § 9601(14).
         3
      The EPA estimated that a final remedy would be in place in
10-15 years.     A "remaining portion" feasibility study was
conducted, and the EPA selected a final remedial action in March




                                   -3-
the City of Odessa's water system should be extended to provide

service in the Odessa Chromium I area.        On September 8, 1986, the

EPA Regional Administrator issued a Record of Decision (ROD),

finding that city water service should be extended to the site.

Pursuant to the cooperative agreement, the State, through its

contractor,    designed   and   constructed    the   system,   which   was

completed in 1988.

                                   II

     In December 1988, the EPA filed a CERCLA cost-recovery action

against Bell, Sequa, and John Leigh, which was consolidated with an

adversary proceeding the EPA had filed against Bell in Bell's

bankruptcy case.     The EPA sought to recover direct and indirect

costs it incurred in studying, designing, and constructing the

alternate water supply system.

     In July 1989, the district court entered a case management

order providing that the case would be decided in three phases:

Phase I--liability, Phase II--recoverability of the EPA's response

costs, and Phase III--"responsibility."         In September 1989, the

district court granted in part, and denied in part, the EPA's

motion for summary judgment as to liability.          In its memorandum

opinion, it stated that the relative culpability of the parties and

the "divisibility of liability" issues would be decided during

Phase III.    Although the district court ruled that CERCLA did not



1988.   Those activities are not at issue in this appeal.




                                   -4-
require the EPA to prove causation, it held an evidentiary hearing

and made alternative findings and conclusions addressing causation,

holding that "Leigh, Bell and Sequa caused the contamination."4           In

March 1990,   the   district   court    granted   the   EPA's   motion   for

clarification of the September 1989 summary judgment, holding that

its previous opinion had provided that the defendants were jointly

and severally liable. It also entered a declaratory judgment as to

the defendants' liability for future response costs.

     The Phase II proceeding on recoverability of response costs

was handled through cross-motions for summary judgment.                  The

district court held that the defendants had not met their burden of

proving that the EPA's decision to implement an alternate water

supply was arbitrary and capricious, and held that they were liable


     4
       Approximately a month after the district court entered its
findings of fact and conclusions of law on causation, our court
decided Amoco Oil Co. v. Borden, Inc., 889 F.2d 664 (5th Cir.
1989).    In Amoco, we noted that, "in cases involving multiple
sources of contamination, a plaintiff need not prove a specific
causal link between costs incurred and an individual generator's
waste." Id. at 670 n.8. Other courts have likewise concluded that
proof of causation is not required in CERCLA cases. E.g., United
States v. Alcan Aluminum Corp. (Alcan-PAS), 990 F.2d 711, 721 (2d
Cir. 1993) (the government is not required to "show that a specific
defendant's waste caused incurrence of clean-up costs"); United
States v. Alcan Aluminum Corp. (Alcan-Butler), 964 F.2d 252, 266
(3d Cir. 1992) ("the Government must simply prove that the
defendant's hazardous substances were deposited at the site from
which there was a release and that the release caused the
incurrence of response costs"); United States v. Monsanto Co., 858
F.2d 160, 170 (4th Cir. 1988) (liability is subject only to the
causation-based affirmative defenses set forth in CERCLA § 107(b);
"Congress has, therefore, allocated the burden of disproving
causation to the defendant who profited from the generation and
inexpensive disposal of hazardous waste.").




                                  -5-
for the EPA's direct and indirect response costs, plus prejudgment

interest from the date such costs were incurred.

     On March 2, 1990, the EPA sought approval of a proposed

consent decree, in which it settled its claims against Bell for all

costs, past and future, for $1,000,000.      Sequa objected to the

settlement, contending that Bell was not being required to pay its

fair share.      The district court granted Sequa's request for a

hearing on the fairness of the proposed consent decree, and entered

an order providing that a Phase III hearing regarding apportionment

of liability was to be conducted before it ruled on the motion for

entry of the consent decree.    In response to the EPA's motion for

clarification of the scope of the hearing, the court ruled that the

hearing would be limited to determining the relative contributions

of Bell, Sequa, and Leigh to the contamination.    After the Phase

III hearing in June 1990, Sequa filed a motion for reconsideration

on the issue of joint and several liability.       On July 24, the

district court denied that motion, and approved the consent decree.

It held that the evidence at the Phase I and Phase III hearings

demonstrated that there was no method of dividing the liability

among the defendants which would rise to any level above mere

speculation, because each of the proposed apportionment methods

involved a significant assumption factor, inasmuch as records had

been lost, and because each of the apportionment methods differed

significantly.     In the alternative, it concluded that, based on




                                 -6-
equitable factors, responsibility should be divided as follows:

Bell--35%; Sequa--35%; and Leigh--30%.

     In   December   1990,    the   district   court   entered   an   order

approving another consent decree, pursuant to which the EPA settled

its claims against Leigh for past and future costs--for $100,000.

     In sum, the district court held that Sequa is jointly and

severally   liable   for     $1,866,904.19,    including   the   costs   of

studying, designing, and constructing the alternate water supply

system. In addition, Sequa is jointly and severally liable for all

future costs incurred by the EPA in studying, designing, and

implementing a permanent remedy.5

                                    III

                           Statutory Background

     CERCLA was enacted in 1980, and amended in 1986 by the

Superfund Amendments and Reauthorization Act (SARA).         Its purpose

is to facilitate the prompt clean-up of hazardous waste sites.

See, e.g., United States v. R. W. Meyer, Inc., 889 F.2d 1497, 1500

(6th Cir. 1989).     CERCLA § 104, 42 U.S.C. § 9604, authorizes the

President (who has delegated most of his authority under CERCLA to

the EPA) to use Superfund money to respond to any threatened or

actual release of any hazardous substance that may pose an imminent

and substantial public health threat.          CERCLA § 107, 42 U.S.C. §


    5
     Although the costs of final remedial action are not at issue
in this appeal, we note that the settlements with Bell and Leigh
encompassed those costs.




                                    -7-
9607, provides for the recovery of response costs from all persons

responsible for the release of a hazardous substance.                   Response

actions include both "remedial" and "removal" actions.                   Removal

actions generally are immediate or interim responses, and remedial

actions    generally    are    permanent        responses.     See      Voluntary

Purchasing, Inc. v. Reilly, 889 F.2d 1380, 1382 n.4 (5th Cir.

1989).

     The National Contingency Plan ("NCP"), 40 C.F.R. Part 300,

promulgated by the EPA as mandated by CERCLA § 105, 42 U.S.C. §

9605, guides federal and state response activities.                      The NCP

identifies methods for investigating the environmental and health

problems   resulting    from    a    release     or   threatened   release   and

criteria   for    determining       the    appropriate   extent    of   response

activities.      See Daigle v. Shell Oil Co., 972 F.2d 1527, 1533 n.4

(10th Cir. 1992); United States v. R. W. Meyer, Inc., 889 F.2d at

1500.

                                          IV

                       Joint and Several Liability

     Since CERCLA's enactment, the federal courts have struggled to

resolve the complicated, often confusing, questions posed by the

concept of joint and several liability, and its application under

a statute whose provisions are silent with respect to the scope of

liability, but whose legislative history is clear that common law




                                          -8-
principles of joint and several liability may affect liability.6

The issue is one of first impression in this Circuit.

                                    A

                Common Law:   The Restatement of Torts

      Although joint and several liability is commonly imposed in

CERCLA cases,7 it is not mandatory in all such cases.             United

States v. Monsanto Co., 858 F.2d at 171.             Instead, Congress

intended that the federal courts determine the scope of liability

in   CERCLA   cases   under   traditional   and   evolving   common   law


      6
       For a discussion of the legislative history regarding the
deletion of joint and several liability provisions from the statute
prior to its enactment, see United States v. Chem-Dyne Corp., 572
F. Supp. 802 (S.D. Ohio 1983); United States v. A & F Materials
Co., Inc., 578 F. Supp. 1249 (S.D. Ill. 1984); and Colorado v.
Asarco, Inc., 608 F. Supp. 1484 (D. Col. 1985).
      7
      Many of the cases in which joint and several liability has
been imposed involve hazardous waste sites at which numerous
substances have been commingled.     See, e.g., United States v.
Stringfellow, 661 F. Supp. 1053, 10609 (C.D. Cal. 1987); United
States v. South Carolina Recycling & Disposal, Inc., 653 F. Supp.
984, 994 (D.S.C. 1986), aff'd in part & vacated in part, United
States v. Monsanto Co., 858 F.2d 160 (4th Cir. 1988); United States
v. Ottati & Goss, Inc., 630 F. Supp. 1361, 1396 (D.N.H. 1985). In
such cases, determining the contribution of each cause to a single
harm will often require a very complex assessment of the relative
toxicity, migratory potential, and synergistic capacity of the
hazardous wastes at issue. See Monsanto, 858 F.2d at 172 & n.26.
Under such circumstances, it is hardly surprising that defendants
have had difficulty in meeting their burden of proving that
apportionment is feasible. See O'Neil v. Picillo, 883 F.2d 176,
178-79 (1st Cir. 1989) ("The practical effect of placing the burden
on defendants has been that responsible parties rarely escape joint
and several liability, courts regularly finding that where wastes
of varying (and unknown) degrees of toxicity and migratory
potential commingle, it simply is impossible to determine the
amount of environmental harm caused by each party."), cert. denied,
493 U.S. 1071 (1990).

principles, guided by the Restatement (Second) of Torts.      Alcan-

Butler, 964 F.2d at 268; O'Neil v. Picillo, 883 F.2d at 178; Allied

Corp. v. Acme Solvents Reclaiming, Inc., 691 F. Supp. 1100, 1116

(N.D. Ill. 1988); Chem-Dyne, 572 F. Supp. at 810.

     Section 433 of the Restatement provides that:

               (1) Damages for harm are to be apportioned
          among two or more causes where

                    (a) there are distinct harms, or

                    (b) there is a reasonable basis for
               determining the contribution of each cause to
               a single harm.

               (2) Damages for any other harm        cannot   be
          apportioned among two or more causes.

Restatement (Second) of Torts, § 433A.

     The nature of the harm is the key factor in determining

whether apportionment is appropriate.    Distinct harms--e.g., where

two defendants independently shoot the plaintiff at the same time,

one wounding him in the arm and the other wounding him in the

leg--are regarded as separate injuries.       Although some of the

elements of damages (such as lost wages or pain and suffering) may

be difficult to apportion, "it is still possible, as a logical,

reasonable, and practical matter, ... to make a rough estimate

which will fairly apportion such subsidiary elements of damages."

Id., comment b on subsection (1).

     The Restatement also discusses "successive" harms, such as

when "two defendants, independently operating the same plant,

pollute a stream over successive periods of time."    Id., comment c




                               -10-
on subsection (1).        Apportionment is appropriate, because "it is

clear that each has caused a separate amount of harm, limited in

time, and that neither has any responsibility for the harm caused

by the other."     Id.

     The final situation discussed by the Restatement in which

apportionment     is     available    involves    a   single    harm       that   is

"divisible"--perhaps        the   most    difficult     type     of    harm       to

conceptualize.      Such harm, "while not so clearly marked out as

severable into distinct parts, [is] still capable of division upon

a reasonable and rational basis, and of fair apportionment among

the causes responsible....           Where such apportionment can be made

without injustice to any of the parties, the court may require it

to be made."     Id., comment d on subsection (1).             Two examples of

such harm are described in the comment.            The first is where cattle

owned by two or more persons trespass upon the plaintiff's land and

destroy   his   crops.       Although    "the    aggregate   harm     is    a   lost

crop, ... it may nevertheless be apportioned among the owners of

the cattle, on the basis of the number owned by each, and the

reasonable      assumption     that     the     respective     harm    done       is

proportionate to that number."           Id.    The second example involves

pollution of a stream by two or more factories.                     There, "the

interference with the plaintiff's use of the water may be treated

as divisible in terms of degree, and may be apportioned among the




                                       -11-
owners of the factories, on the basis of evidence of the respective

quantities of pollution discharged into the stream."       Id.8

       Apportionment is inappropriate for other kinds of harm, which,

"by their very nature, are normally incapable of any logical,

reasonable, or practical division."       Id., comment on subsection

(2).     Examples of such harm are death, a single wound, the

destruction of a house by fire, or the sinking of a barge.        "Where

two or more causes combine to produce such a single result,

incapable of division on any logical or reasonable basis, and each

is a substantial factor in bringing about the harm, the courts have

refused to make an arbitrary apportionment for its own sake, and

each of the causes is charged with responsibility for the entire

harm."    Id.

       Apportionment is also inappropriate in what the Restatement

describes as "exceptional" cases, "in which injustice to the

plaintiff may result."     Id., comment h on subsection (1).        For

example, "one of two tortfeasors [may be] so hopelessly insolvent

that the plaintiff will never be able to collect from him the share

of the damages allocated to him."       Id.   Where the court deems it

unjust to require the innocent plaintiff to bear the risk of one of



         8
        The Restatement points out that apportionment also is
appropriate where part of the harm is the result of an innocent
cause, id., comment e on subsection (1), or where the plaintiff is
responsible for a portion of the harm.         Id., comment f on
subsection (1).




                                 -12-
the tortfeasors' insolvency, it may refuse to apportion damages in

such a case.    Id.

     In sum, the nature of the harm is the determining factor with

respect to whether apportionment is appropriate.               Ultimately, the

decision whether to impose joint and several liability turns on

whether there is a reasonable and just method for determining the

amount of harm that was caused by each defendant (or, in some

cases, by an innocent cause or by the fault of the plaintiff).                The

question    whether     the     harm   to   the    plaintiff   is   capable    of

apportionment among two or more causes is a question of law.

Restatement (Second) of Torts, § 434(1)(b).                  Once it has been

determined that the harm is capable of being apportioned among the

various causes of it, the actual apportionment of damages is a

question of fact.       Id., § 434(2)(b) & comment d.

     Section 433B of the Restatement sets forth the burdens of

proof.     As a general rule, the plaintiff must prove that the

defendant's tortious conduct caused the harm.               Id., § 433B(1).    As

we have already noted, however, this rule does not apply in CERCLA

cases. See note 4, supra.         Nevertheless, subsection (2) of § 433B,

which    sets   forth     the     burdens     of    proof    with   respect    to

apportionment, does apply and provides as follows:

            Where the tortious conduct of two or more actors
            has combined to bring about harm to the plaintiff,
            and one or more of the actors seeks to limit his
            liability on the ground that the harm is capable of
            apportionment among them, the burden of proof as to
            the apportionment is upon each such actor.




                                       -13-
As explained in the comment, this rule applies only to "a proved

wrongdoer who has in fact caused harm to the plaintiff."              Id.,

comment d on subsection (2).        Thus, the rule stated in subsection

(2) will not permit a defendant to escape liability altogether, but

only to limit its liability, if it can meet its burden of proving

the amount of the harm that it caused.          If it is unable to do so,

it is liable for the full amount of the harm.            According to the

Restatement, the typical case to which this rule applies "is the

pollution of a stream by a number of factories which discharge

impurities into it."       Id., comment c on subsection (2).

     Comment e notes that there is a possibility that the rule

stated   in   subsection    (2)   may   cause   disproportionate   harm   to

defendants where each of a large number of them contributes a

relatively small and insignificant part to the total harm.                For

example, "if a hundred factories each contribute a small, but still

uncertain, amount of pollution to a stream, to hold each of them

liable for the entire damage because he cannot show the amount of

his contribution may perhaps be unjust."              Id., comment e on

subsection (2). The comment, however, expresses no conclusion with

respect to the applicability of this illustration, noting that such

a case had not arisen.

     CERCLA is a strict liability statute, one of the purposes of

which is to shift the cost of cleaning up environmental harm from

the taxpayers to the parties who benefited from the disposal of the

wastes that caused the harm.       See, e.g., Chem-Dyne, 572 F. Supp. at




                                    -14-
805-06.    "The improper disposal or release of hazardous substances

is an enormous and complex problem of national magnitude involving

uniquely federal interests."        Id. at 808.    Often, liability is

imposed upon entities for conduct predating the enactment of

CERCLA, and even for conduct that was not illegal, unethical, or

immoral at the time it occurred.         We recognize the importance of

keeping these facts in mind when attempting to develop a uniform

federal common law for CERCLA cases.        We also recognize, however,

that CERCLA, as a strict liability statute that will not listen to

pleas of "no fault," can be terribly unfair in certain instances in

which parties may be required to pay huge amounts for damages to

which their acts did not contribute.          Congress recognized such

possibilities and left it to the courts to fashion some rules that

will,     in   appropriate   instances,    ameliorate    this   harshness.

Accordingly, Congress has suggested, and we agree, that common-law

principles of tort liability set forth in the Restatement provide

sound guidance.     In applying those principles to this CERCLA case,

we think that it will be helpful to examine briefly some of the

relevant CERCLA jurisprudence.

                                     B

                             The Jurisprudence

     The first published case to address the scope of liability

under CERCLA is United States v. Chem-Dyne Corp., 572 F. Supp. 802

(S.D. Ohio 1983), which was cited approvingly in the legislative

history of the SARA amendments to CERCLA.               In that case, 24




                                   -15-
defendants,   who   allegedly   generated   or    transported   hazardous

substances located at Chem-Dyne's treatment facility, sought "an

early determination" that they were not jointly and severally

liable for the EPA's response costs.     Id. at 804.    After examining

the statute and its legislative history, the court concluded that

provisions for joint and several liability were deleted from CERCLA

"in order to avoid its universal application to inappropriate

circumstances."     Id. at 810.    It relied on the Restatement for

guidance in applying federal common law.         Id.

     The court described the nature of the "fairly complex factual

determination" involved in deciding whether the defendants were

jointly and severally liable as follows:

          The Chem-Dyne facility contains a variety of
          hazardous   waste    from    289   generators    or
          transporters, consisting of about 608,000 pounds of
          material. Some of the wastes have commingled but
          the identities of the sources of these wastes
          remain unascertained. The fact of the mixing of
          the wastes raises an issue as to the divisibility
          of the harm. Further, a dispute exists over which
          of the wastes have contaminated the ground water,
          the degree of their migration and concomitant
          health hazard. Finally, the volume of waste of a
          particular generator is not an accurate predictor
          of the risk associated with the waste because the
          toxicity or migratory potential of a particular
          hazardous substance generally varies independently
          with the volume of the waste.

Id. at 811.   The court concluded that the defendants had not met

their burden of demonstrating the divisibility of the harm and the

degree to which each was responsible, and denied their motion for

summary judgment.    Id.




                                  -16-
     United States v. Ottati & Goss, Inc., 630 F. Supp. 1361

(D.N.H. 1988), was a cost recovery action against operators and

former   operators    of   drum   reconditioning   businesses,   property

owners, and generators of wastes contained in the drums that were

sent to the site for reconditioning.            The evidence showed that

chemical substances leaked or spilled from drums and were mixed

together.    Although the generators satisfied their burden of

proving approximately how many drums each brought to the site, the

court nevertheless imposed joint and several liability, because

"the exact amount or quantity of deleterious chemicals or other

noxious matter [could not] be pinpointed for as to each defendant[,

and] [t]he resulting proportionate harm to surface and groundwater

[could not] be proportioned with any degree of accuracy as to each

individual defendant."      Id. at 1396.

     A similar situation existed in O'Neil v. Picillo, 883 F.2d 176

(1st Cir. 1989).     The site at issue there was a Rhode Island pig

farm that had been used as a waste disposal site.           The site was

described as having "massive trenches and pits `filled with free-

flowing, multi-colored, pungent liquid wastes' and thousands of

`dented and corroded drums containing a veritable potpourri of

toxic fluids.'"      Id. at 177.     The defendants argued that it was

possible to apportion the removal costs, because there was evidence

of the total number of barrels excavated during each phase of the

clean-up, the number of barrels in each phase attributable to them,

and the cost of each phase.       Id. at 181.   There was testimony that,




                                    -17-
of the approximately 10,000 barrels excavated, only 300-400 could

be attributable to a particular defendant.               Id. at 182.   The court

concluded that because most of the waste could not be identified,

and   the    defendants   had     the     burden    of    accounting   for    the

uncertainty, the imposition of joint and several liability was

appropriate.9

      On the other hand, the Third Circuit reversed a summary

judgment in favor of the EPA, and remanded the case for further

factual development on the scope of liability, in United States v.

Alcan Aluminum Corp. (Alcan-Butler), 964 F.2d 252, 255 (3d Cir.

1992).      This case involved the Butler Tunnel Site, a network of

approximately five square miles of underground mines, tunnels,

caverns, pools, and waterways, drained by the Butler Tunnel into

the Susquehanna River in Pennsylvania.             During the 1970s, millions

of gallons of liquid wastes containing hazardous substances were

disposed of through a borehole that led directly into the mine

workings.      In 1985, 100,000 gallons of contaminated water were

released from the site into the river.

      The    government   filed    a    cost-recovery      action   against   20

defendants; all but Alcan settled.             The district court granted


      9
     The court noted that, even if there had been evidence of the
number of barrels attributable to each defendant, more would be
required to demonstrate that the removal costs were capable of
apportionment, because the cost of removing barrels varied
depending upon their contents. Furthermore, the costs of removing
contaminated soil, in which the wastes had commingled, "would
necessarily be arbitrary." Id. at 183 n.11.




                                        -18-
summary judgment for the government, holding that Alcan was jointly

and severally liable for the response costs.           The Third Circuit

held that the "intensely factual nature of the `divisibility'

issue" highlighted the district court's error in granting summary

judgment without conducting a hearing.        Id. at 269.    It remanded

the case in order to give Alcan the opportunity to limit or avoid

liability by attempting to prove its personal contribution to the

harm to the Susquehanna River.       Thus, under the Third Circuit's

approach, Alcan could escape liability altogether if it could prove

that its "emulsion did not or could not, when mixed with other

hazardous wastes, contribute to the release and the resultant

response costs."    Id. at 270.

     The   Third   Circuit   noted   that   the   analysis   involved   in

apportioning several liability is similar to that involved in

apportioning damages among jointly and severally liable defendants

in an action for contribution, because both focus on what harm was

caused by the defendant.     Id. at 270 n.29.     However, it stated that

the issue of joint and several liability should be resolved at the

initial liability stage, rather than at the contribution stage.10

It noted that drastic consequences could result from delaying that

determination, because "a defendant could easily be strong-armed


      10
       Because contribution is only available among jointly and
severally liable tortfeasors, the imposition of several liability
for all defendants would obviate the necessity for a contribution
phase. See, e.g., Environmental Transportation Systems, Inc. v.
Ensco, Inc., 969 F.2d 503, 508 (7th Cir. 1992).




                                  -19-
into settling where other defendants have settled in order to avoid

being held liable for the remainder of the response costs."              Id.

It    also noted   that   contribution   would   not   be   available   from

settling defendants, pursuant to CERCLA § 113(f)(2).11          Id.

       The Second Circuit essentially adopted the Third Circuit's

approach to joint and several liability in another case involving

Alcan, United States v. Alcan Aluminum Corp. (Alcan-PAS), 990 F.2d

711 (2d Cir. 1993).        That case involved a waste disposal and

treatment center operated during the 1970s by Pollution Abatement

Services (PAS).     Alcan used PAS for the disposal or treatment of

4.6 million gallons of oil emulsion.         The government brought a

cost-recovery action against 83 defendants.            As in Alcan-Butler,

all of the defendants except Alcan settled.            The Second Circuit

reversed a summary judgment in favor of the government, stating

that "Alcan should have the opportunity to show that the harm

caused at PAS was capable of reasonable apportionment."               Id. at

722. It held that Alcan was entitled to "present evidence relevant

to establishing divisibility of harm, such as, proof disclosing the

relative toxicity, migratory potential, degree of migration, and

synergistic capacities of the hazardous substances at the site."

Id.


       11
      That section provides that "[a] person who has resolved its
liability to the United States in an administrative or judicially
approved settlement shall not be liable for claims for contribution
regarding matters addressed in the settlement."        42 U.S.C. §
9613(f)(2).




                                  -20-
       The court stated that Alcan could escape liability if it could

prove that its oil emulsion, when mixed with other hazardous

wastes, did not contribute to the release and resulting clean-up

costs.    It acknowledged that "causation is being brought back into

the case--through the backdoor, after being denied entry at the

frontdoor--at the apportionment stage."               Id.   However, it pointed

out that causation was "reintroduced only to permit a defendant to

escape payment where its pollutants did not contribute more than

background contamination and also cannot concentrate."                 Id.

       With respect to the timing of the joint and several liability

inquiry, the Second Circuit stated that it preferred the Third

Circuit's "common sense approach."             Id.    It ultimately concluded,

however, that "the choice as to when to address divisibility and

apportionment are questions best left to the sound discretion of

the trial court in the handling of an individual case."                     Id. at

723.

       A "moderate" approach to joint and several liability was

adopted in United States v. A & F Materials Co., Inc., 578 F. Supp.

1249 (S.D. Ill. 1984).      That case involved a disposal site at which

over    7,000,000   gallons       of   waste   were    deposited.     The    court

concluded that a rigid application of the Restatement approach to

joint    and   several   liability       was    inappropriate.        Under    the

Restatement     approach,     a    defendant     who    could   not   prove    its

contribution to the harm would be jointly and severally liable.

The court thought that such a result would be inconsistent with




                                        -21-
congressional intent, because Congress was "concerned about the

issue of fairness, and joint and several liability is extremely

harsh and unfair if it is imposed on a defendant who contributed

only a small amount of waste to a site."         Id. at 1256.

      The   court   concluded   that   six    factors   delineated   in   an

unsuccessful amendment to CERCLA proposed by Representative (now

Vice President) Gore could be used to "soften" the modern common

law   approach   to   joint   and   several   liability   in   appropriate

circumstances.      Under this "moderate" approach, a court has the

power to impose joint and several liability upon a defendant who

cannot prove its contribution to an injury, but it also has the

discretion to apportion damages in such a situation according to

the "Gore factors":

                 (i) the ability of the parties to demonstrate
            that their contribution to a discharge[,] release
            or   disposal   of  a  hazardous   waste  can   be
            distinguished;
                 (ii) the amount of the hazardous waste
            involved;
                 (iii) the degree of toxicity of the hazardous
            waste involved;
                 (iv) the degree of involvement by the parties
            in the generation, transportation, treatment,
            storage, or disposal of the hazardous waste;
                 (v) the degree of care exercised by the
            parties with respect to the hazardous waste
            concerned, taking into account the characteristics
            of such hazardous waste; and
                 (vi) the degree of cooperation by the parties
            with Federal, State, or local officials to prevent
            any harm to the public health or the environment.

Id. at 1256.     The court stated that its moderate approach would

promote fairness by allowing courts to be sensitive to the inherent




                                    -22-
unfairness    of    imposing      joint    and   several   liability       on    minor

contributors, and to make rational distinctions based on such

factors as the amount and toxicity of a particular defendant's

contribution to a waste site.             Id. at 1257.

     In Allied Corp. v. Acme Solvents Reclaiming, Inc., 691 F.

Supp. 1100 (N.D. Ill. 1988), a private cost recovery action in

which the government was not a party, the court adopted the A & F

moderate approach to joint and several liability.                        However, it

expressed no opinion on the propriety of that approach in cost

recovery actions involving the government as plaintiff.                         Id. at

1118 & n.12.

     The A & F moderate approach, to the extent it is inconsistent

with the Chem-Dyne approach to joint and several liability, was

rejected in United States v. South Carolina Recycling and Disposal,

Inc., 653 F. Supp. 984 (D.S.C. 1986), aff'd in part and vacated in

part, United States v. Monsanto Co., 858 F.2d 160 (4th Cir. 1988).

That case involved a site at which there were "thousands of

corroded, leaking drums ... not segregated by source or waste type.

Unknown, incompatible materials commingled to cause fires, fumes,

and explosions."          653 F. Supp. at 994.             The district court

concluded    that   the    harm    was    indivisible,     because       all    of   the

substances at the site contributed synergistically, and it was

impossible to ascertain the degree or relative contribution of each

substance.     Id.        The   court     rejected   volume   as     a    basis      for

apportionment, finding that it "is not an accurate predictor of the




                                          -23-
risk associated with the waste because the toxicity or migratory

potential of a particular hazardous substance generally varies

independently of the volume."          Id. at 995 (quoting Chem-Dyne, 572

F. Supp. at 811).      The court concluded that "[s]uch arbitrary or

theoretical   means    of    cost    apportionment    do   not   diminish   the

indivisibility    of   the    underlying     harm,   and   are   matters    more

appropriately considered in an action for contribution between

responsible parties after plaintiff has been made whole."                Id.

     On appeal, the Fourth Circuit affirmed the imposition of joint

and several liability.          858 F.2d at 173.           It noted that the

generator defendants had presented no evidence of a relationship

between the volume of waste, the release of hazardous substances,

and the harm at the site.        Because the substances had commingled,

apportionment was impossible "without some evidence disclosing the

individual and interactive qualities of the substances deposited

there."    Id. at 172.        Because "[c]ommon sense counsels that a

million gallons of certain substances could be mixed together

without significant consequences, whereas a few pints of others

improperly mixed could result in disastrous consequences," the

court concluded that evidence of the relative toxicity, migratory

potential, and synergistic capacity of the various substances was

both relevant and necessary.         Id. at 172 & n.26.      The court noted,

however,   that   under      other   circumstances,    volume    could     be   a

reasonable basis for apportioning liability, in a situation in




                                      -24-
which independent factors had no substantial effect on the harm to

the environment.     Id. at 172 & n.27.

      The Fourth Circuit apparently agreed with the district court's

rejection of the A & F moderate approach, stating that, while

equitable factors are relevant in an action for contribution,

"[t]hey are not pertinent to the question of joint and several

liability, which focuses principally on the divisibility among

responsible parties of the harm to the environment."            858 F.2d at

171 n.22.     Other courts have similarly concluded that equitable

factors, such as those listed in the Gore amendment, have no place

in   making   the   decision   whether    to   impose   joint   and   several

liability, but are appropriate in an action for contribution among

jointly and severally liable defendants.           See Alcan-Butler, 964

F.2d at 270 n.29 ("the contribution proceeding is an equitable one

in which a court is permitted to allocate response costs based on

factors it deems appropriate, whereas the court is not vested with

such discretion in the divisibility determination"); United States

v. Western Processing Co., Inc., 734 F. Supp. 930, 938 (W.D. Wash.

1990) ("defendants may ... bring contribution actions for ultimate

allocation of damages among the responsible parties where it is

entirely appropriate to utilize the Gore Factors to determine the

burden each party must bear"); United States v. Stringfellow, 661

F. Supp. at 1060 ("the Court's discretion in apportioning damages




                                   -25-
among        the   defendants   during   the    contribution   phase    does   not

[a]ffect the defendants' liability").12

     To summarize, our review of the jurisprudence leads us to

conclude that there are three distinct, although closely-related,

approaches to the issue of joint and several liability.                 The first

is the "Chem-Dyne approach," which relies almost exclusively on the

principles of the Restatement (Second) of Torts.                       Under that

approach, a defendant who seeks to avoid the imposition of joint

and several liability is required to prove the amount of harm it

caused.

     The second approach, the "Alcan approach," is adopted by the

Second and Third Circuits.          Although that approach also relies on

the Restatement, it recognizes that, under the unique statutory

liability scheme of CERCLA, the plaintiff's common law burden of

proving causation has been eliminated.             Under the Restatement, the

plaintiff must first prove that the defendant's conduct was a

substantial factor in causing the harm; the defendant may limit its

liability by proving its contribution to the harm.                In contrast,

the Alcan approach suggests that a defendant may escape liability

altogether if it can prove that its waste, even when mixed with



        12
      Our court has also held that the Gore factors are relevant
in apportioning damages in an action for contribution. Amoco v.
Borden, Inc., 889 F.2d at 672-73.        See also Environmental
Transportation Systems, Inc. v. Ensco, Inc., 969 F.2d at 507-09;
United States v. R. W. Meyer, Inc., 932 F.2d 568, 571 (6th Cir.
1991); O'Neil v. Picillo, 883 F.2d at 179.




                                         -26-
other wastes at the site, did not cause the incurrence of response

costs.

     The third approach is the "moderate" approach taken in A & F.

Under that approach, the court applies the principles of the

Restatement in determining whether there is a reasonable basis for

apportionment.    If there is not, the court may impose joint and

several liability; the court, however, retains the discretion to

refuse to impose joint and several liability where such a result

would be inequitable.

     Although these approaches are not entirely uniform, certain

basic principles emerge. First, joint and several liability is not

mandated under CERCLA; Congress intended that the federal courts

impose joint and several liability only in appropriate cases,

applying common-law principles.       Second, all of the cases rely on

the Restatement in resolving the issues of joint and several

liability.     The major differences among the cases concern the

timing of the resolution of the divisibility question, whether

equitable factors should be considered, and whether a defendant can

avoid liability for all, or only some portion, of the damages.

Third, even where commingled wastes of unknown toxicity, migratory

potential, and synergistic effect are present, defendants are

allowed   an   opportunity   to   attempt   to   prove   that   there   is   a

reasonable basis for apportionment (although they rarely succeed);

where such factors are not present, volume may be a reasonable

means of apportioning liability.




                                   -27-
     With respect to the timing of the "divisibility" inquiry, we

believe that an early resolution is preferable.   We agree with the

Second Circuit, however, that this is a matter best left to the

sound discretion of the district court.    We also agree with the

majority view that equitable factors, such as those listed in the

Gore amendment, are more appropriately considered in actions for

contribution among jointly and severally liable parties, than in

making the initial determination of whether to impose joint and

several liability.13   We therefore conclude that the Chem-Dyne

    13
      In adopting the majority view, we do not intend to imply that
concerns for fairness and avoiding injustice should never be
considered in deciding whether joint and several liability is
appropriate. In this respect, we note that the legislative history
of the SARA amendments to CERCLA, which created an express
statutory right of contribution, cites the A & F decision for the
proposition that the Gore factors may be considered in determining
whether to grant apportionment in an action for contribution; see
H.R. Rep. No. 253, 98th Cong., 2d Sess., pt. 3, at 19 (1985), 1986
U.S.C.C.A.N. 2835; the legislative history also cites Chem-Dyne for
the proposition that the party seeking apportionment has the burden
of establishing that it should be granted.          Both of those
decisions, however, deal with apportionment in terms of whether
joint and several liability should be imposed, rather than in terms
of contribution among jointly and severally liable parties.
Considering CERCLA's "well-deserved notoriety for vaguely-drafted
provisions and an indefinite, if not contradictory, legislative
history," we do not view these citations as a basis for courts to
determine joint and several liability based on those factors. See
Amoco, 889 F.2d at 667.
     As discussed in the Restatement comments, there may be
exceptional cases in which it would be unjust to impose several
liability, such as when one of the defendants is so hopelessly
insolvent that the plaintiff will be unable to recover any damages
from it. We believe, however, that consideration of such factors
will rarely be appropriate or necessary in CERCLA cases, especially
when the plaintiff is the government.       Under CERCLA's strict
liability scheme, the deck of legal cards is heavily stacked in
favor of the government.      The legislative history shows that
because Congress was concerned about the potential harshness or




                               -28-
approach is an appropriate framework for resolving issues of joint

and several liability in CERCLA cases.     Although we express no

opinion with respect to the Alcan approach, because it is not

necessary with respect to the issues we are faced with in this

case, we nevertheless recognize that the Restatement principles

must be adapted, where necessary, to implement congressional intent

with respect to liability under the unique statutory scheme of

CERCLA.14




unfairness to defendants, it refused to adopt mandatory joint and
several liability in order to give courts the ability to ameliorate
such results in appropriate cases.        We do not consider the
financial condition of Leigh or Bell to be relevant to the decision
in this case.   The EPA entered into its settlements with those
defendants with full awareness of Sequa's opposition to the
settlements, as well as to the imposition of joint and several
liability.

    14
      The dissent's proposal for an "equitable divisibility" phase
is indeed creative. Notwithstanding our respect for so fertile a
mind, we do not believe that the plain language of CERCLA will
support the application of such equitable factors in determining
liability. Under CERCLA, a defendant has contribution rights only
against other defendants who have not resolved their liability in
an administrative or judicially approved settlement.      CERCLA §
113(f), 42 U.S.C. § 9613(f).     No provision of CERCLA grants a
defendant a right to hold the EPA liable for eliminating its
contribution rights by entering into consent decrees with other
jointly and severally liable defendants. In sum, CERCLA simply
does not contemplate a proceeding in which a jointly and severally
liable, non-settling defendant can force the EPA to bear the costs
resulting from settlements that, although judicially approved, are
later thought, for equitable reasons, to be unfair or otherwise
inadequate. Because the EPA settled with Bell and Leigh (pursuant
to judicially-approved consent decrees which are not before us on
appeal), there can be no action for contribution. We cannot agree
that the EPA "bargained" for the risk that its consent decrees with
Bell and Leigh would be undermined in such a manner.

                 Application of Joint & Several Liability

       We now turn to consider the application of these traditional

and evolving common law principles of joint and several liability

to the facts of this case.

       First,    we   conclude        that       the   district     court   erred     in

determining that there is no reasonable basis for apportionment.

We reject the EPA's assertion that the clearly erroneous standard

of    review    applies    to   these    findings        of   the   district     court.

According to the Restatement, "the question whether the harm to the

plaintiff is capable of apportionment among two or more causes is

a question of law."         Restatement (Second) of Torts, § 434.

       In the district court, the EPA contended that there was no

reasonable basis for apportionment, because the harm to the Trinity

Aquifer was a single harm, and a that single harm is the equivalent

of an indivisible harm, thus mandating the imposition of joint and

several liability.        Apparently now recognizing the lack of support

for    that     position,15     the    EPA       on    appeal     acknowledges      that

apportionment is available, at least theoretically, when there is

a reasonable basis for determining the contribution of each cause

to a single harm.         It asserts, however, that Sequa failed to meet

its burden of proof on that issue.                      Sequa responds that the

      15
     The Second and Third Circuits have rejected similar arguments
by the EPA. See, e.g., Alcan-PAS, 990 F.2d at 722 (rejecting the
EPA's contention that "commingled" waste is synonymous with
"indivisible" harm); Alcan-Butler, 964 F.2d at 270 n.29 (same).




                                         -30-
district court was misled by the EPA's incorrect view of the law,

and erroneously required it to prove a certain--as opposed to

reasonable--basis for apportionment.

     Essentially, the question whether there is a reasonable basis

for apportionment depends on whether there is sufficient evidence

from which the court can determine the amount of harm caused by

each defendant.      If    the   expert     testimony    and   other   evidence

establishes a factual basis for making a reasonable estimate that

will fairly apportion liability, joint and several liability should

not be imposed in the absence of exceptional circumstances.                 The

fact that apportionment may be difficult, because each defendant's

exact contribution to the harm cannot be proved to an absolute

certainty, or the fact that it will require weighing the evidence

and making credibility determinations, are inadequate grounds upon

which to impose joint and several liability.16

     Our review of the record convinces us that Sequa met its

burden of proving that, as a matter of law, there is a reasonable

basis for apportionment.         This case is closely analogous to the

Restatement's illustrations in which apportionment of liability is

appropriate.     For example, where cattle owned by two or more

defendants     destroy    the    plaintiff's    crops,     the   damages   are


    16
      Of course, making such apportionment decisions should not be
difficult for any factfinder that has been called on to apportion
fault under comparative negligence statutes. Such decisions are
rarely, if ever, made on the basis of evidence showing to a
certainty the proportion of each party's fault.




                                     -31-
apportioned     according        to   the    number       of    cattle    owned       by    each

defendant, based on the reasonable assumption that the respective

harm done is proportionate to that number.                      Thus, the Restatement

suggests that apportionment is appropriate even though the evidence

does not establish with certainty the specific amount of harm

caused by each defendant's cattle, and even though there is a

possibility that only one of the defendant's cattle caused all of

the harm,     while   the    other      defendant's            cattle    idly    stood      by.

Likewise, pollution of a stream by two or more factories may be

treated as divisible in terms of degree, and apportioned among the

defendants on the basis of evidence of the respective quantities of

pollution discharged by each.

     As    is    evident         from   our        previous       discussion          of    the

jurisprudence, most CERCLA cost-recovery actions involve numerous,

commingled      hazardous    substances         with       synergistic      effects         and

unknown toxicity.           In    contrast,        this    case    involves          only   one

hazardous substance--chromium--and no synergistic effects.                                  The

chromium    entered    the       groundwater         as    the     result       of    similar

operations by three parties who operated at mutually exclusive

times.    Here, it is reasonable to assume that the respective harm

done by each of the defendants is proportionate to the volume of

chromium-contaminated water each discharged into the environment.

     Even though it is not possible to determine with absolute

certainty the exact amount of chromium each defendant introduced

into the groundwater, there is sufficient evidence from which a




                                            -32-
reasonable         and    rational   approximation     of   each   defendant's

individual contribution to the contamination can be made.                  The

evidence demonstrates that Leigh owned the real property at the

site        from   1967   through    1981,    and   conducted   chrome-plating

activities there in 1971 and 1972.              In 1972, Bell purchased the

assets of the shop and leased the property from Leigh.                      It

continued to conduct similar, but more extensive, chrome-plating

activities there until mid-1976.             In August 1976, Sequa purchased

the assets from Bell, leased the property from Leigh, and conducted

similar chrome-plating activities at the site until late 1977.              In

response to the EPA's motion for summary judgment, Sequa introduced

evidence regarding chrome flake purchases during each operator's

tenure.       It also introduced evidence with respect to the value of

the chrome-plating done by each, as well as summaries of sales.

Given the number of years that had passed since the activities were

conducted, the records of these activities were not complete.17

However, there was testimony from various witnesses regarding the

rinsing and wastewater disposal practices of each defendant, and

the amount of chrome-plating activity conducted by each.18




       17
      Sequa's records prior to 1977 had been destroyed pursuant to
its records-retention policy.
       18
      The evidence is conflicting on some points, such as the date
Sequa installed a wastewater tank and how many times that tank
overflowed.    Of course, such credibility determinations and
resolution of conflicts in the evidence are for the district court.




                                       -33-
     During   the    Phase   III     hearing,     Sequa    introduced   expert

testimony regarding a volumetric approach to apportionment.                 The

first expert, Henderson, calculated the total amount of chromium

that had been introduced into the environment by Leigh, Bell, and

Sequa, collectively and individually.            The second expert, Mooney,

calculated the amount of chromium that would have been introduced

into the environment by each operator on the basis of electrical

usage records.

     In addition to rejecting apportionment because of competing

theories, the district court also rejected volume as a basis for

apportionment,    because    there    was   no    method    of   dividing   the

liability among the defendants which would rise to any level of

fairness above mere speculation.            It stated that each of the

proposed apportionment methods involved significant assumption

factors, because records had been lost, and because the theories

differed significantly.

     The existence of competing theories of apportionment is an

insufficient reason to reject all of those theories.               It is true,

as the district court noted, that the records of chrome-plating

activity   were     incomplete.       However,      under    the   facts    and

circumstances of this case, and in the light of the other evidence

that is available, that factor may be taken into account in

apportioning Sequa's share of the liability.                Finally, the fact

that Sequa's experts relied on certain assumptions in forming their

opinions is not fatal to Sequa's ability to prove that there is a




                                     -34-
reasonable basis for apportionment.    Expert opinions frequently

include assumptions.   If those assumptions are well-founded and

reasonable, and not inconsistent with the facts as established by

other competent evidence, they may be sufficiently reliable to

support a conclusion that a reasonable basis for apportionment

exists.19

     In sum, we conclude that the district court erred in imposing

joint and several liability, because Sequa met its burden of

proving that there is a reasonable basis for apportioning liability

among the defendants on a volumetric basis.    We therefore remand

the case to the district court for apportionment.




     19
      The dissent's assertion that we are advocating a standard of
proof of less than a preponderance of the evidence is incorrect.
Sequa is, of course, required to prove its contribution to the harm
by a preponderance of the evidence. Our point is that such proof
need not rise to the level of certainty; evidence sufficient to
permit a rough approximation is all that is required under the
Restatement. Although the dissent acknowledges that certainty is
not required, the evidence it would require Sequa to adduce in
order to escape joint and several liability rises far above the
level necessary to satisfy the preponderance of the evidence
standard. We seriously doubt that any CERCLA defendant would ever
be able to satisfy the dissent's rigorous proof requirements--which
would be the equivalent of a mandate of joint and several liability
in all CERCLA cases. Congress clearly had no such intention. In
any event, the district court, apparently misled by the EPA's
erroneous argument that a single harm cannot be apportioned, never
had an opportunity to apply the appropriate legal principles to the
factual questions of apportionment. As we have noted, the district
court had already decided that the defendants were jointly and
severally liable long before the Phase III hearing, at which the
bulk of the evidence regarding divisibility was introduced.

                     Alternate Water Supply System

     Sequa    also   challenges   the   EPA's   decision    to   provide   an

alternate water supply (AWS) as an interim measure pending the

completion of final remedial action.        The scope of our review of

the EPA's selection of the AWS is governed by the 1986 amendments

to CERCLA, which provide that such review is "limited to the

administrative record."     42 U.S.C. § 9613(j)(1).        We are to uphold

the EPA's decision "unless the objecting party can demonstrate, on

the administrative record, that the decision was arbitrary and

capricious or otherwise not in accordance with law."             42 U.S.C. §

9613(j)(2).

             The scope of review under the "arbitrary and
             capricious" standard is narrow and a court is not
             to substitute its judgment for that of the agency.
             Nevertheless, the agency must examine the relevant
             data and articulate a satisfactory explanation for
             its action including a rational connection between
             the facts found and the choice made....         In
             reviewing that explanation, we must consider
             whether the decision was based on a consideration
             of the relevant factors and whether there has been
             a clear error of judgment.

Motor Vehicle Manufacturers Ass'n v. State Farm Mutual Automobile

Ins. Co., 463 U.S. 29, 43 (1983) (citations and internal quotation

marks omitted).

     Sequa challenges the EPA's decision to provide the AWS on a

number of grounds, including that:        (1) the administrative record

demonstrates that the EPA failed to recognize that "substantial

danger to public health or the environment," as specified in the




                                   -36-
National Contingency Plan, is the standard against which the

decision to implement an alternative water supply system must be

measured; (2) there is no analysis of why the EPA believed the

public health was at risk and required protection at the subject

site; (3) the Safe Drinking Water Act's maximum contaminant level

for chromium is based on a lifetime (70-year) exposure, but the

alternate water supply system was merely a short-term (10-15 year)

response; further, the administrative record contains no discussion

of whether chromium presents a danger to humans on the basis of

short-term   exposure;     and   (4)    the   EPA   failed    to    analyze   the

likelihood that the contaminated water would be ingested.

     The EPA's defense of its decision to implement the alternate

water supply system is, we think, singularly weak.                      The EPA

contends primarily that we should defer to its technical expertise.

It argues that the existence of chromium at levels exceeding the

maximum contaminant level allowed under the SDWA presumptively

establishes that its response was appropriate.               We cannot agree.

     Although the arbitrary and capricious standard of review is

very lenient on the agency, and we will not substitute our judgment

for that of the agency, "[j]udicial review `must be based on

something    more   than   trust   and    faith     in   EPA's     experience.'"

American Petroleum Institute v. E.P.A., 661 F.2d 340, 349 (5th Cir.

1981) (quoting Appalachian Power Co. v. Train, 545 F.2d 1351, 1365

(4th Cir. 1976)).      Our determination of whether the EPA's decision

was arbitrary and capricious must be made on the basis of the




                                       -37-
rationale relied on by the EPA as contained in the administrative

record.     We will not accept the EPA's post-hoc rationalizations in

justification of its decision, nor will we attempt to supply a

basis for its decision that is not supported by the administrative

record.      See State Farm, 463 U.S. at 50.20

       After   thoroughly    reviewing   the   administrative     record,    we

conclude that the EPA's decision to furnish the AWS was arbitrary

and capricious.       In vain we have searched the over 5,000 pages of

administrative record, and found not one shred of evidence that

anyone in the area was actually drinking chromium-contaminated

water.      Amazingly, the EPA made no attempt to learn whether anyone

was drinking the water, or whether anyone intended to utilize the

AWS, until after it had made its decision to construct the AWS.

One would think that surely such information was essential in order

to reach an informed, rational decision as to whether an AWS was

necessary, and whether it would reduce any significant threat to

public      health.    The   administrative    record   reveals    that     the

chromium-contaminated wells in the area all served commercial

establishments, which the EPA prohibited from connecting to the

AWS.   Moreover, the EPA did not require residents to connect to the

       20
       For this reason, the dissent's reliance on the EPA's 1986
decision. The same is true with respect to the August 19, 1987,
Record of Communication quoted by the dissent in footnote 6 is
inappropriate, post-hoc rationalization.     The only information
relevant to our determination of whether the EPA's decision was
arbitrary and capricious is the information that the EPA relied on
in making that decision.     Events occurring subsequent to the
decision cannot be relied upon to support it.

system, and did not prohibit them from using contaminated water

from their wells. Thus, on the basis of the administrative record,

it appears that the AWS did not even reduce, much less eliminate,

any public health threat.   No technical expertise is necessary to

discern that the EPA's implementation of the AWS was arbitrary and

capricious, as well as a waste of money.21

                            All Costs?

     Having determined that the EPA's decision to implement the AWS

was arbitrary and capricious, we must now decide whether the EPA

nevertheless is entitled to recover its costs for designing and

constructing the AWS.

     CERCLA § 107 provides for the recovery of the following costs:

               (A) all costs of removal or remedial action
          incurred by the United States Government or a State
          or an Indian tribe not inconsistent with the
          national contingency plan;

                (B) any other necessary costs incurred by any
          other    person   consistent  with   the   national
          contingency plan;

               (C) damages for injury to, destruction of, or
          loss of natural resources, including the reasonable

     21
      The dissent criticizes our performance of what we perceive
to be our proper role of judicial review, because we have not
meekly deferred to EPA's scientific expertise regarding the need
for an alternate water supply system.        But even the dissent
recognizes that CERCLA requires the EPA to take measures that will
minimize threats to public health and the environment. The dissent
has not explained how any potential threats to the public health
were minimized by the alternate water supply system, when the EPA
did not require residents to connect to the new system and did not
prohibit them from using contaminated water from their wells.




                               -39-
          costs of assessing such injury, destruction, or
          loss resulting from such a release; and

               (D) the costs of any health assessment or
          health effects study carried out under section
          9604(i) of this title.

42 U.S.C. § 9607(a)(4) (emphasis added).

     Sequa contends that the EPA is authorized to recover only

reasonable and necessary costs, relying on the statutory language

as well as federal procurement laws and regulations. The EPA takes

the position that it is entitled to recover all costs--even if

unreasonable or unnecessary22--unless Sequa proves that such costs

are inconsistent with the National Contingency Plan.23 The district

    22
     Other courts apparently have agreed with EPA's interpretation
of CERCLA § 107(a)(4)(A).      In United States v. Northeastern
Pharmaceutical & Chemical Co., Inc., 810 F.2d 726 (8th Cir. 1986),
the court noted that § 107(a)(4)(A) does not refer to "all
reasonable costs" but simply to "all costs," and concluded that
"`all costs' incurred by the government that are not inconsistent
with the NCP are conclusively presumed to be reasonable." Id. In
United States v. Hardage, 982 F.2d 1436 (10th Cir. 1992), the court
likewise stated that, "[a]s long as the government's choice of
response action is not inconsistent with the NCP, its costs are
presumed to be reasonable and therefore recoverable." Id. at 1443.
Cf. United States v. R. W. Meyer, Inc., 889 F.2d at 1504 (emphasis
added) ("to the extent cleanup actions are necessary, ... the
statute contemplates that those responsible for hazardous waste at
each site must bear the full cost of cleanup actions").
     23
       A majority of courts have held that, under § 107(a)(4)(A),
the defendant has the burden of proving that the government's costs
are inconsistent with the NCP. E.g., Hardage, 982 F.2d at 1442;
Northeastern, 810 F.2d at 747; Ottati & Goss, 630 F. Supp. at 1395;
United States v. Conservation Chemical Co., 619 F. Supp. 162, 186
(W.D. Mo. 1985); United States v. Ward, 618 F. Supp. 884, 899
(E.D.N.C.   1985).      In   contrast,    under   §   107(a)(4)(B),
nongovernmental entities are required to prove that their response
costs are necessary and consistent with the NCP.        County Line
Investment Co. v. Tinney, 933 F.2d 1508, 1512 & n.8 (10th Cir.
1991); Northeastern, 810 F.2d at 726. In Alcan-PAS, 990 F.2d at




                               -40-
court held that the EPA could recover all of its response costs, so

long as they were not the product of "gross misconduct" by the

agency.

     Although we approve of the district court's attempt to impose

some restraints on the EPA's ability to recover costs from private

parties, we find no statutory basis for its "gross misconduct"

limitation.   Nevertheless, we are troubled by the implications of

the EPA's position on this issue.             Sequa contends that, under the

EPA's interpretation, defendants will be liable even if the EPA

allows a    contractor    to   pay     its    officers   and   other    employees

unjustified millions and allows each of them a Rolls-Royce for

transportation.   Interestingly, the EPA did not attempt to refute

Sequa's assertion,       either   in    its    appellate   brief   or    at   oral

argument.   Instead, the EPA asserts a policy reason to support its

interpretation:

            By refusing to permit defendants to defend against
            cost recovery actions by engaging in detailed
            attacks on the "reasonableness" of individual
            government cost items, Congress provided an
            incentive to those defendants to conduct the
            necessary response actions themselves.       Where
            defendants refuse to conduct the appropriate
            response actions, CERCLA allows the Government to
            undertake the response actions it deems necessary
            and appropriate without being constrained by the
            possibility that each line item of the costs of
            these actions will be challenged in cost recovery.


719-20, the Second Circuit stated that the government must
establish that the costs it incurred conform to the NCP; however,
in support of that proposition, it cited B. F. Goodrich Co. v.
Murtha, 958 F.2d 1192, 1198 (2d Cir. 1992), a private cost-recovery
action under § 107(a)(4)(B).




                                       -41-
In addition, the EPA asks us to take comfort in the fact that,

through internal agency audits and other forms of self-policing,

costs will be controlled.

     Acceptance of the EPA's position would effectively prohibit

judicial review of the EPA's expenditures. In short, we would give

the EPA       a    blank    check   in   conducting     response     actions.24    We

seriously         doubt    that   Congress   intended    to   give    the   EPA   such

unrestrained         spending     discretion.25       Moreover,      such   unbridled

discretion removes any restraint upon the conduct of the EPA in

exercising its awesome powers; if the EPA knows there are no


         24
        We note that CERCLA requires that remedial (permanent)
actions be cost-effective; however, there is no corresponding
requirement with respect to removal (interim) actions. 42 U.S.C.
§ 9621(b).    The NCP implements this statutory directive by
requiring the EPA to consider cost with respect to remedial
alternatives, and to select a cost-effective remedial measure. See
Hardage, 982 F.2d at 1443.     The Tenth Circuit has held that a
contention that an individual cost is excessive or unreasonable
does not demonstrate inconsistency with the NCP; instead, a
defendant "must show that the government acted arbitrarily and
capriciously in failing to consider cost, or in selecting a
remedial alternative that is not cost-effective." Id.
    25
      Because challenges to EPA's response actions are not subject
to judicial review outside the context of a cost-recovery or
administrative enforcement action, the EPA has control over the
timing of judicial review.    See 42 U.S.C. § 9613(h); Voluntary
Purchasing Groups, Inc. v. Reilly, 889 F.2d 1380 (5th Cir. 1989).
Thus, the EPA may complete a response action, and wait to seek
recovery of its costs after they have already been incurred. If
EPA's decision to incur costs is later determined by a court to be
arbitrary and capricious, or inconsistent with the NCP, the
Superfund will not be reimbursed for EPA's expenditures. Even if
Congress contemplated that all of EPA's decisions would be upheld,
we would be reluctant to conclude that it gave the EPA the
authority to waste Superfund money simply because such funds could
later be recovered from the pockets of private parties.

economic consequences to it, its decisions and conduct are likely

to be less responsible.

        We do not have to decide the question in this case, however,

because        the    only    costs    Sequa   challenges   as   unreasonable    and

unnecessary           are    those    associated   with   implementation    of   the

alternate water supply system, a decision that we have already

concluded was arbitrary and capricious. The Tenth Circuit recently

held that, "[t]o show that the government's response action is

inconsistent with the NCP, a defendant must demonstrate that the

EPA acted arbitrarily and capriciously in choosing a particular

response action to respond to a hazardous waste site."                     Hardage,

982 F.2d at 1442.             We find this reasoning persuasive, as well as

adequate for resolving the issue before us, and therefore adopt

it.26        Because the decision to implement an AWS was arbitrary and

capricious, it is inconsistent with the NCP.                Accordingly, the EPA

is not entitled to recover the costs of designing and constructing

the AWS.

        We realize that, as a result of our decision disallowing the

EPA's costs for the AWS, those costs will have to be borne by the

Superfund.           Although regrettable, this is the inevitable result of

arbitrary and capricious EPA decisionmaking.                 Without knowing, or

even attempting to learn, whether the AWS would serve to protect

the safety and health of anyone, the EPA officiously ignored the

        26
      We express no opinion on whether § 107(a)(4)(A) permits the
EPA to recover unreasonable, unnecessary, or excessive costs.

comments of Bell and Sequa, and the results of its own remedial

investigation, and stubbornly proceeded to spend over $300,000 to

furnish a water supply system that was not needed, was not allowed

to be used by the commercial establishments whose wells (according

to the administrative record) were the only ones with chromium

contamination   in   excess      of   the    SDWA    standards,    and   did   very

little--indeed, if anything--to reduce any perceived public health

threat posed by the chromium-contaminated groundwater. We can only

assume that the EPA was not concerned about the cost of the AWS,

because it believed that it could recover whatever was spent from

Sequa.    Although the EPA's powers under CERCLA are indeed broad,

Congress has not provided that private parties must pay for the

consequences of arbitrary and capricious agency action.

                               Settlement Credit

     CERCLA § 113(f)(2), 42 U.S.C. § 9612(f)(2), provides that a

settlement by one defendant "reduces the potential liability to the

others by the amount of the settlement."                   Bell and Leigh settled

with the EPA for a combined total of $1.1 million.                 Sequa contends

that the district court (1) improperly refused to credit that

amount against the total recovery obtained by the government; and

(2) erred in allocating the Bell settlement proceeds, $1,000,000,

first to amounts for which Bell was severally liable (litigation

costs    incurred   by   the    EPA   in    the     Bell    bankruptcy   adversary




                                      -44-
proceeding before suit was filed against Sequa), and then toward

costs for which Bell and Sequa were jointly and severally liable.

      Because § 113(f)(2) logically can be applied only to reduce a

defendant's joint and several liability, which we have decided is

inappropriate in this case, we need not address this issue.

                                          VIII

                                 Prejudgment Interest

      CERCLA § 107(a)(4) provides for the recovery of prejudgment

interest, which "shall accrue from the later of (i) the date

payment of a specified amount is demanded in writing, or (ii) the

date of the expenditure concerned."                42 U.S.C. § 9607(a)(4).        The

district court awarded prejudgment interest calculated from the

date of expenditures.

      Sequa contends that the statute requires a written demand for

a   specified     amount      of    response     costs   before    any   prejudgment

interest    may      be    awarded.      The   EPA   does    not    contest   Sequa's

assertion that a written demand is required, but contends that the

notices sent to Sequa, advising it generally that the United States

considered      it    to    be     potentially    liable    for    response   costs,

satisfied that requirement. The EPA further contends that the 1986

ROD to install the alternate water supply system put Sequa on

notice of the potential cost of that decision.                     Finally, the EPA

asserts    that      the    complaint    constitutes       the    necessary   written

demand.




                                          -45-
     The statute plainly requires a written demand for specified

response costs             as   a   prerequisite      to     an   award   of    prejudgment

interest.       Neither the notices informing Sequa that generally the

EPA would look to it for potential reimbursement "at some future

time,"    nor     the      ROD      satisfy    that    requirement.        Although        the

complaint does not specify an exact amount, we conclude that it

constitutes a sufficient written demand for payment.                           We therefore

hold that, with respect to costs incurred before the complaint was

filed, prejudgment interest should be assessed from the date the

complaint was filed. With respect to costs, if any, incurred after

the complaint was filed, prejudgment interest should be assessed on

those costs from the date of the expenditures.

     The judgment of the district court is REVERSED insofar as it

imposes joint and several liability and allows recovery of the

costs of designing and constructing the AWS; the portion of the

judgment awarding prejudgment interest is VACATED; and the case is

REMANDED for further proceedings consistent with this opinion.

prejudgment interest issue. However, I must dissent in substantial

part from the majority opinion, for the following reasons.

                        Joint and Several Liability

     I cannot agree with the majority's holding on the joint and

several liability/quantitative apportionment issue in this case.

I do agree that the determination of whether the type harm involved

in this case is capable of quantitative apportionment is a question

of law.    And the majority is correct that the single chromium harm

suffered by the Trinity Aquifer is the sort theoretically capable

of apportionment.       However, while Sequa met its legal burden of

establishing     that    the   type    harm   involved   is   capable   of

apportionment, it failed to meet its factual burden relative to

apportionment.     If proof exists by which the fact-finder could

determine, on a reasonable basis, the extent of environmental

injury attributable to a party, then certainly that party is

entitled to escape the heavy hand of joint and several liability

and to have its liability restricted to its actual, quantitative

contribution to the single harm. The majority correctly places the

burden of proof on the party seeking such a finding, to produce

credible evidence to meet its burden.         But the majority confuses

the distinction between the legal burden that the single harm at

issue caused is of a type capable of apportionment, and the factual

burden of proving the amount of harm attributable to a particular




                                      -47-
                                       47
party.    See majority opinion at ____ ("Our review of the record

convinces us that Sequa met its burden of proving that, as a matter

of law, there is a reasonable basis for apportionment."              This case

is closely analogous to the Restatement's illustrations in which

apportionment of liability is appropriate.").

      The gist of the majority opinion is this legal fallacy:

because the evidence is clear that Sequa did not cause 100% of the

harm to the aquifer, Sequa must be entitled to a finding by the

district court apportioning the amount of harm attributable to it

under the Restatement (Second) of Torts, § 433.            We are not to

approach our analytical task from that end.         The majority's "rule

of thumb" miscasts the role of the district court and eviscerates

the very concept of joint and several liability.

      I agree with the majority that certainty is not required.

What is required is proof by a preponderance of the evidence.             The

majority properly embraces the applicability of the Restatement

(Second) of Torts to this case, but then seeks to divorce itself

from the applicable preponderance of the evidence standard of proof

so   as   to   mandate   that   the   district   court   "pick   a    number"

apportioning liability.

                                       48
     Civil cases are decided by a preponderance of the evidence

because such proof affords a reasonable basis for decision.         In

other words, while certainty of proof is not required in civil

cases, probability is.   Evidence by "fifty-one percent," or to the

extent of "more likely than not," is deemed sufficiently reliable

for resolution of civil disputes.       But proof by less than this

amount    is   unacceptably   speculative;   and   amounts   to   mere

possibility, not probability. Dean William Prosser said it well in

his influential treatise:

        On the issue of the fact of causation, . . . [the one
     bearing the burden of proof by a preponderance of the
     evidence] must introduce evidence which affords a
     reasonable basis for the conclusion that it is more
     likely than not that [the causation exists].      A mere
     possibility of such causation is not enough;[ ] and when
     the matter remains one of pure speculation or
     conjecture,[ ] or the probabilities are at best evenly
     balanced,[ ] it becomes the duty of the court to direct
     a verdict for the defendant. Where the conclusion is not
     one within the common knowledge of laymen, expert
     testimony may provide a sufficient basis for it, [ ] but
     in the absence of such testimony it may not be drawn.1

If proof by a preponderance of the evidence is to be abandoned in

CERCLA apportionment cases, the district court is at least entitled

to guidance regarding the level of possibilities that is

acceptable.   Will 10% do?   20%?   30%?2

     The majority quotes the Restatement's § 433:

     (1) Damages for harm are to be apportioned among two or
     more causes where

         (a) there are distinct harms, or

        (b) there is a reasonable basis for determining the
     contribution of each cause to a single harm.

     (2) Damages for any other harm cannot be apportioned
     among two or more causes.

The majority proceeds to quote comment d on subsection (1) of this

Section, to the effect that a single harm that is conceptually

divisible, "while not so clearly marked out as severable into

distinct parts, [is] still capable of division upon a reasonable

and rational basis, and of fair apportionment among the causes

responsible . . . .   Where such apportionment can be made without

injustice to any of the parties, the court may require it to be

made."   The majority discusses two examples of such harm given in

this comment:   the first being where cattle owned by two or more

persons trespass upon another's land and destroy the other's crops;

and the second involving the pollution of a stream by two or more

       The majority, in a footnoted dissent to my dissent, asserts
that it has adhered to the preponderance of the evidence standard.
To the contrary, the majority has not done so.        Also in its
"majority dissent," the majority calls the standard I have
articulated a "rigorous" one, "far above the level necessary to
satisfy the preponderance of the evidence standard." The second
part of this "majority dissent" assertion is also just not so. The
first part of it (about it being "rigorous") is so only to the
extent the majority finds the fundamental civil case standard of
preponderance of the evidence too "rigorous" to be applied in this
case.

factories.    But in both of these examples, as the Restatement's

comment explains, a reasonable, factual basis for division must

exist   in   order    for   the   court    to       actually   draw     the       possible

apportionment.       In the cattle example, the comment explains that,

although "the    aggregate        harm    is    a    lost   crop,   .   .     .    it   may

nevertheless be apportioned among the owners of the cattle, on the

basis of the number owned by each, and the reasonable assumption

that the respective harm done is proportionate to that number."                          In

the stream pollution example, the comment makes it plain that "the

interference with the plaintiff's use of the water may be treated

as divisible in terms of degree, and may be apportioned among the

owners of the factories, on the basis of evidence of the respective

quantities of pollution discharged into the stream."                               If the

Restatement (Second) of Tort's term, "reasonable basis," as used in

the majority opinion, means something other than preponderance of

the evidence, the majority should at least say so, and why.

     "As other courts have noted, apportionment itself is an

intensely factual determination."              United States v. Alcan Aluminum

Corp., 990 F.2d 711, 722 (2nd Cir. 1993) (citing e.g., United

States v. Chem-Dyne Corp., 572 F. Supp. 802, 811 (S.D. Ohio 1983)).

The example used by the majority is a good one.                 If cows belonging

to Farmers A and B damage another's crop, that is the type harm

that as a matter of law is capable of apportionment.                     However, to

evade joint and several liability, Farmer A or B must meet the

burden of proving that apportionment is reasonable on some basis,




                                         -51-
                                          51
such as the number of cows in the field belonging to each farmer or

the amount of time each farmer's cows were in the field.             Proof

that each farmer had some unknown number of cows in the field, or

that an established number of cows belonging to each farmer were in

the field for some unknown period of time, is not enough -- because

under such circumstances the fact-finder is left to speculate on

the question of the amount of harm reasonably attributable to each

farmer's cows.

     In this case an experienced and careful district judge heard

and reviewed the quantitative apportionment testimony and exhibits

in this case, and it possessed opportunities to assess their

convincingness far superior to those of this (appellate) court.

The district court found Sequa failed to meet its quantitative

apportionment burden of proof by a preponderance of the credible

evidence.     That finding is reviewable at the Court of Appeals only

on the basis of whether it was clearly erroneous.            The district

court's finding was not clearly erroneous.

     The district court afforded Sequa its full apportionment due

-- the opportunity to avoid joint and several liability by meeting

its burden of proof through the presentation of credible evidence

persuading the district court that the amount of harm caused by

Sequa   can   be   apportioned   to   a   level   of   knowledge   that   is

sufficiently reliable (i.e., by a preponderance of the evidence).

Sequa simply failed to meet its burden.            The majority opinion

notwithstanding, there is no reason to believe Sequa's appellate




                                  -52-
                                   52
claim that the district court applied the wrong standard for

apportionment (i.e., a standard of certainty, as opposed to the

appropriate standard, of a reasonable basis). Rather, the district

court's analysis, in the record, demonstrates that court's clear

understanding of and application of the appropriate reasonable

basis standard for apportionment questions like the one it faced.

See e.g., District Court Order of May 9, 1990 (emphasis added here)

("this Court is of the opinion the chromium contamination found in

the ground waters below the Odessa I Site is not divisible.           The

evidence at both the Phase I and Phase III hearings clearly

demonstrated there is no method of dividing the liability among the

Defendants which would rise to any level of fairness above mere

speculation.   * * *    Having heard the evidence adduced at trial of

Phase III, this Court is of the opinion none of the [defendants'

proffered   methods    of   actual   quantitative   apportionment]   offer

viable methods for dividing liability among John Leigh, Bell or

Sequa.").

     The majority remands the case to the district court for a

finding apportioning liability on a volumetric basis.          Such was,

however, precisely the purpose of Phase III of the trial.       In Phase

III of the trial, the district court heard approximately 400 pages

of testimony from 19 witnesses, 3 of whom were experts.               The

district court reviewed over 150 exhibits:          80 new exhibits were

admitted during Phase III of the trial; and the district court




                                     -53-
                                      53
allowed for the more than 70 exhibits from Phase I to also be used

during Phase III.

      A review of the record reveals that Sequa attempted to climb

the preponderance hill by focusing on several potential methods of

achieving a reasonable basis for quantitative apportionment of

liability on a volumetric basis.

      Under one proffered method of such apportionment by a Sequa

expert, the expert assumed that Sequa's electrical usage for

plating operations was 30% of its total electrical usage, while, in

contrast, he attributed to both Bell and Leigh a plating percentage

of 50% of their respective total electrical usages.         But the bases

for   this     expert's   electrical      percentage    assumptions        were

effectively refuted by other evidence in the case.

      Sales records served as the springboard for another proffered

method of apportionment.         The sales record approach suffered

fatally from Sequa's ability to produce only scattered invoices.

      An attempt was then made to compare the defendants' expense

records.     However, the only expense records for Sequa demonstrated

that it purchased 3,500 pounds of chromic acid flake within a three

month period in 1977.     Sequa's other records were destroyed.            Any

attempt to extrapolate from the three month period in 1977 would

have been at best speculative.

      A Sequa expert also assumed that Sequa had no waste disposal

after the installation of a catch tank.         The credibility of this

assumption     was   fatally   eroded   by   contrary    evidence     --    of




                                   -54-
                                    54
substantial overflows, spills of plating solution, leaks in the

plating tanks, and plating solution dumped by Sequa.

     Indeed, the only evidence the district court could view with

any comfort was evidence of relative times of facility ownership

and the periods of plating activity by the defendants.    Yet, the

apportionment import of even this evidence was reduced to mere

speculation when attempts were made to prove the actual level, or

quantity, of plating activity conducted during the known periods of

time.    In the language of the majority's cited example of cows in

the field:    the defendants evidenced what periods of time each

farmer had cows in the field, but failed to demonstrate to any

degree above speculation how many cows each farmer had in the

field.

     This case is a simple one by CERCLA standards.      But it is

nonetheless quite typical of CERCLA-apportionment cases:     years

after the pollution at issue, it is very difficult for a defendant

to prove by a preponderance of the evidence even its rough share of

responsibility for the single harm caused by pollution.    This is

why the equitable (contribution) phase of CERCLA response cost

proceedings is so important -- as Congress expressly recognized in

the 1986 amendments to CERCLA (SARA). See H.R. No. 99-253(I), 99th

Cong., 2d Sess. 79, reprinted in 1986 U.S.C.C.A.N. 2835, 2861 (SARA

"confirms" federal right of contribution under CERCLA); see also

United States v. Alcan Aluminum Corp., 990 F.2d 711, 724 (2nd Cir.

1993) ("In [SARA] courts are granted implicit authority, using




                                -55-
                                 55
appropriate equitable factors, to 'allocate response costs among

liable parties.'") (emphasis added) (quoting O'Neil v. Picillo, 883

F.2d 176, 179 (1st Cir. 1989)).       Sequa's evidence will not improve

upon remand.    There is no more apportionment evidence available.

Unless the district court's view of the evidence on remand is

somehow "enlightened" by the majority's view of the evidence, the

district court will have to apply a standard of proof of less than

a preponderance of the evidence in order to reach a decision in

conformity with the apportionment result mandated by the majority.

      Actually, the district court did attempt to "apportion" the

defendants' liability on a basis other than a reasonable,               amount

of contribution basis -- by making alternative findings on a purely

equitable basis taking into account the facts that:            Bell occupied

the site for the longest period of time; Sequa gained access to the

measures to correct the contamination were necessary; and Leigh

accrued the least financial gain from the chrome plating venture,

but cooperated with the government in the government's efforts to

discover the sources of the contamination.               The district court

apportioned the defendants' equitable responsibility for costs at

35% each to Bell and Sequa, and 30% to Leigh.            See District Court

Order of May 9, 1990 ("this Court is of the opinion the liability

attacked by Sequa on quantitative apportionment and equitable cost

allocation      grounds],    this   Court       is     of     the   opinion      the

responsibility for costs should be divided roughly equally among

the parties with Bell and Sequa shouldering 35% of the burden each

and john [sic] Leigh shouldering 30%.                      The reasons for such

division are purely equitable, as Bell occupied the Site for the

longest period of time and Sequa gained access to the Site with

knowledge that chromium contamination was a problem and measures to

correct the contamination were necessary."                 John Leigh accrued the

least financial gain from his chromium-plating venture and has

cooperated      at   every   juncture    with        the     Government    in    the

government's efforts to discover the sources behind the chrome

contamination.").

       The adoption of the Chem-Dyne approach in Part IV (B) of the

majority opinion precludes such equitable apportionment except as

part   of   a   contribution   claim    proceeding.           I   agree   with   the

majority's embrace of the Chem-Dyne approach.                     But I think we

should address the impact of the Leigh and Bell consent decrees

upon Sequa's SARA-bestowed contribution rights -- in light of the

alternative, equitable divisibility determinations already rendered

by the district court after its "Phase III" hearing on the issue of

the "relative contributions of Bell, Sequa and John Leigh to the




                                    -57-
                                     57
contamination at the . . . Site."3        In my opinion, the following is

the appropriate appellate court approach to this case.

      First, we should hold that the district court was not clearly

erroneous in its finding that Sequa failed to meet its burden of

proof on the factual, quantitative apportionment issue -- of

Sequa's proportionate responsibility for the single chromium harm

suffered by the aquifer.         Then, we should reject the district

court's conclusion that, in this case, it did not need to consider

the fairness of the proposed consent decrees relative to Sequa's

SARA-bestowed, equitable cost allocation rights.          See 42 U.S.C. §

9613 (f)(1).      I think we must address the impact of the consent

decrees on the defendants' statutory equitable cost allocation

rights -- in light of the alternative, equitable "apportionment"

finding reasonably rendered by the district court.            This approach

is   consistent    with   the   caselaw    on   appropriate    contribution

analyses.4    And my approach certainly offers a much better prospect

than does a remand to the district court for more (essentially

redundant) proceedings.

                        Equity and 42 U.S.C. § 9613

       As the majority has noted, after concluding that Sequa had

failed to meet its burden of demonstrating a reasonable fact basis

for    apportionment     of    the        relative     responsibilities      of    the

defendants, the district court rendered an alternative, purely

equitable       "apportionment"       determination.            In   reaching      its

alternative conclusion, the district court considered the following

equitable facts:        that Bell occupied the site for the longest

period of time; that Sequa gained access to the site with knowledge

that chromium contamination was a problem and measures to correct

the contamination were necessary; and that Leigh accrued the least

financial gain from the chrome plating venture, but cooperated with

the government in the government's efforts to discover the sources

of    the   contamination.          The    district    court    "apportioned"      the

defendants' equitable responsibility for costs at 35% each to Bell

and    Sequa,    and   30%    to    Leigh.       While    the   district     court's

alternative       equitable        findings      are    not    articulated    as    a

"contribution claim" adjudication, I would hold that they satisfy



     including the price paid and discounts granted, should be
     weighed in allocating response costs.[ ].

the essential requirements of CERCLA § 9613 (f)(1), and that they

are consistent with this Circuit's decision in Amoco Oil Co. v.

Borden, 889 F.2d 664 (5th Cir. 1989) -- and thus, that they are

sufficient to constitute contribution findings based in equity.

     In light of the procedural posture of this case and, in

particular, in light of the district court's reasonably based, 35%

- 35% - 30%, "purely equitable" "apportionment" findings, the

parameters of Sequa's equity rights are plainly such that it would

be inequitable and violative of the contribution claims provision

of SARA, 42 U.S.C. § 9613 (f)(1), for those rights to be destroyed

by the Leigh and Bell consent decrees.

     Consistent with CERCLA § 9613 (f)(1) and § 9613 (f)(2), I

would hold that when, in a case such as this one, the EPA finds it

advantageous to enter into a settlement with jointly and severally

liable defendants, thereby shielding the settling defendants from

contribution liability (by operation of CERCLA § 113(f)(2)), the

EPA must bear the risk of its bargain being proved less than

satisfying   upon   district   court   resolution   of   a    non-settling

defendant's, consent decree-attacking, § 9613 (f)(1) equitable cost

allocation claim.    Under the facts of this case, the EPA cannot

have it both ways.      It cannot enjoy the benefits of joint and

several liability and at the same time enter into consent decrees

with the otherwise jointly and severally liable defendants to

destroy a non-settling defendant's statutory right to an equitable

allocation of costs under 42 U.S.C. § 9613 (f)(1).           The majority's




                                  -60-
                                   60
sanctioning of such enjoyment by the government improperly allows

the government to smelt what is plainly intended by Congress to be

a   defendant's     rights   provision     (42   U.S.C.     §    9613)    into   a

governmental sword against defendants.

      Under   the    facts   of   this   case,    Sequa's       equitable    cost

allocation rights are not limited to 42 U.S.C. § 9613 (f)(2), which

provision focuses on providing for offset contribution.                  In short,

because Sequa raised its claims for an equitable, proportionate

cost allocation ruling in what amounts to a contribution claims

proceeding -- before the district court embraced the consent

decrees shielding Bell and Leigh, under 42 U.S.C. § 9613 (f)(2),

from contribution liability -- Sequa is entitled to invoke the

broader equitable response cost allocation remedy contained in 42

U.S.C. § 9613 (f)(1).        Compare 42 U.S.C. § 9613 (f)(1) (emphasis

added here) ("Any person may seek contribution from any person who




                                    -61-

is liable or potentially liable under section 9607 (a) . . . .    In

resolving contribution claims, the court may allocate response

costs among liable parties using such equitable factors as the

court determines are appropriate."), with 42 U.S.C. § 9613 (f)(2)

(emphasis added here) ("A person who has resolved its liability to

the United States or a State in an administrative or judicially

approved settlement shall not be liable for claims for contribution

regarding matters addressed in the settlement.       Such settlement

does not discharge any of the other potentially liable persons

unless its terms so provide, but it reduces the potential liability

of the others by the amount of the settlement.").5

                                II

                   Alternate Water Supply System

     I further disagree with the majority's treatment of Sequa's

challenge to the EPA's decision to provide an alternate water

supply system (AWS) to the chromium-affected area as an interim

measure pending the completion of final remedial action.      We are

supposed to uphold the EPA's decision "unless the objecting party

can demonstrate, on the administrative record, that the decision

was arbitrary and capricious or otherwise not in accordance with

law."   CERCLA, § 113 (f)(2), 42 U.S.C. § 9613 (f)(2).    I think it

        5
          Of course, at the time of a hearing considering the
appropriateness or inappropriateness of a consent decree, the
would-be settling defendant is still "potentially liable" under 42
U.S.C. § 9607(a). See also Amoco Oil Co. v. Borden, 889 F.2d 664,
672 (5th Cir. 1989) ("a court has considerable latitude in
determining each party's equitable share.").

is clear that Sequa has again failed to meet its burden of proof.

     In 1983, the Supreme Court held:

     The scope of review under the "arbitrary and capricious"
     standard is narrow and a court is not to substitute its
     judgment for that of the agency.      Nevertheless, the
     agency must examine the relevant data and articulate a
     satisfactory explanation for its action including a
     rational connection between the facts found and the
     choice made . . . . In reviewing that explanation, we
     must consider whether the decision was based on a
     consideration of the relevant factors and whether there
     has been a clear error of judgment.

Motor Vehicle Manufacturers Ass'n v. State Farm Mutual Automobile

Ins. Co., 463 U.S. 29, 43 (1983) (citations omitted; internal

quotation marks omitted).     A year later, in Chevron U.S.A. v.

Natural Resources Defense Council, Inc., 467 U.S. 837 (1984), the

Supreme Court further clarified that when a court has determined

the intent of Congress is statutorily vague or ambiguous with

respect to the specific issue before the court, the court must

defer to the "reasonable policy choice" of the agency charged with

administering the statute.    467 U.S. at 843-845.

     State Farm and Chevron make it plain that the courts are not

to second-guess the scientific judgments of the EPA.           The EPA

Administrator may apply his or her expertise to draw conclusions

from suspected, but not completely substantiated, relationships

between   facts,   from   trends    among   facts,   from   theoretical

projections from imperfect data, from probative preliminary data

not yet certifiable as "fact," and the like.         See Ethyl Corp. v.

require us to abdicate our judicial duty to carefully review the

record in order to ensure that the agency has made a reasoned

decision based on reasonable extrapolations from some reliable

evidence, the agency's decision need only be reasonable in light of

the facts reflected in the administrative record and under the

applicable statute(s) and regulations; it need not be the "best" or

"most reasonable" decision.            See generally Chevron, supra.         The

majority opinion notwithstanding:             in this case, the agency's AWS

decision   was    both    a   permissible,      reasonable    reading   of   the

operative CERCLA provisions -- and the NCP -- under Chevron, and

not otherwise arbitrary or capricious under State Farm.

                              The Statutory Regime

     It will most often be true that the general aims and policies

of a controlling statute will be evident from its text.                 United

States v. Gaubert, -- U.S. --, --, 111 S.Ct. 1267, 1274 (1991).               It

is evident from CERCLA's text that CERCLA's purpose is to enable

the executive branch (i.e., the EPA) to target and clean up

hazardous waste sites in an efficient manner; and the Superfund

amendments   of    1986       [SARA]    have    undoubtedly    clarified     and

strengthened the executive's CERCLA responsibilities and authority.

See J. V. Peters & Co., Inc. v. Administrator, EPA, 767 F.2d 263,

264 (6th Cir. 1985).          In order to effectuate CERCLA's purposes,

Congress delegated very broad powers to the EPA -- for the agency

to reasonably interpret the CERCLA statutory scheme and respond to

hazardous   substance   scenarios    in   accordance   with   such

interpretation.

                               65
     In particular, the EPA is under the broad statutory obligation

to expeditiously react to any release or threatened release of

hazardous substances that may pose harm to the public health,

welfare or to the environment.     CERCLA, § 101 (23), 42 U.S.C. §

9601(23)   (emphasis   added).    There   are   two   types    of   CERCLA

reactions, or responses, envisioned by the statute:           (1) removal

actions, or interim measures like the AWS at issue in this case;

and (2) remedial, or permanent measures.        "Removal actions" are

defined as actions designed to effect an interim solution to a

contamination problem, but very vaguely:

     "remove" or "removal" means the cleanup or removal of
     released hazardous substances from the environment, such
     actions as may be necessary taken in the event of the
     threat of release of hazardous substances into the
     environment, such actions as may be necessary to monitor,
     assess, and evaluate the release or threat of release of
     hazardous substances, the disposal of removed material,
     or the taking of such other actions as may be necessary
     to prevent, minimize, or mitigate damage to the public
     health or welfare or to the environment, which may
     otherwise result from a release or threat of release.
     The term includes, in addition, without being limited to,
     security fencing or other measures to limit access,
     provision of alternate water supplies, temporary
     evacuation and housing of threatened individuals not
     otherwise provided for, action taken under section
     9604(b) of this title, and any emergency assistance which
     may be provided under the Disaster Relief and Assistance
     Act.

National Contingency Plan, 40 C.F.R. § 300.6 (Definitions) (1986).

"Remedial actions" are defined as actions designed to effect a

permanent solution to the contamination problem, but they are

defined just as vaguely:

      "remedy" or "remedial action" means those actions
      consistent with permanent remedy taken instead of or in
      addition to removal actions in the event of a release or
      threatened release of hazardous substance into the
      environment, to prevent or minimize the release of
      hazardous substances so that they do not migrate to cause
      substantial danger to present or future public health or
      welfare or the environment. The term includes, but is
      not limited to, such actions at the location of the
      release as storage, confinement, perimeter protection
      using   dikes,   trenches,   or  ditches,   clay   cover,
      neutralization, cleanup of released hazardous substances
      or contaminated materials, recycling or reuse, diversion,
      destruction, segregation of reactive wastes, dredging or
      excavations, repair or replacement of leaking containers,
      collection of leachate and runoff, onsite treatment or
      incineration, provision of alternative water supplies,
      and any monitoring reasonably required to assure that
      such actions protect the public health and welfare and
      the environment.

CERCLA, § 101(24), 42 U.S.C. § 9601(24) (emphasis added).          See also

National Contingency Plan, 40 C.F.R. § 300.6 (Definitions) (1986).

      CERCLA provides some much more specific requirements for the

EPA's response actions, as well. For example, where groundwater is

contaminated by chromium, the maximum contaminant levels allowed by

the Safe Drinking Water Act (SDWA), 42 U.S.C. 300f, are "applicable

or relevant and appropriate standards," for agency decisionmaking

if the groundwater is a potential drinking water supply. 42 U.S.C.

§   9621(d)(2)(A).   Chromium   is   one   element   for   which   maximum

concentration limits ("MCLs") were set under the SDWA.              CERCLA

nonetheless defines a "potential drinking water supply" quite

broadly -- as "any raw or finished water source that is or may be

used by a public water system * * * or as drinking water by one or




                                -68-

more individuals.   42 U.S.C. § 9601(7) (emphasis added).6      Clearly,

the agency's determination that the sole source, Trinity Aquifer

falls within the statute's drinking water supply definition was not

arbitrary or capricious, and reflects a reasonable construction and

implementation of the EPA's broad CERCLA enforcement license.

                                    B

                    The National Contingency Plan

     As the majority has stated, the National Contingency Plan

(NCP) guides federal and state response activities by specifically

identifying methods for investigating the environmental and health

problems   resulting   from   a   release   or   threatened   release   of

hazardous substances, and establishing criteria for determining the

appropriate extent of response activities.         The 1986 NCP was the

operative one in this case.




    6
      It is also illuminating that CERCLA § 118, 42 U.S.C. § 9618
-- part of the 1986, SARA amendments to CERCLA -- made explicit
that the executive branch is to give high priority to contaminated
drinking water supplies. Section 118 provides:
        For purposes of taking action under section 9604 or
     9606 of this title and listing facilities on the National
     Priorities List, the President shall give a high priority
     to facilities where the release of hazardous substances
     or pollutants or contaminants has resulted in the closing
     of drinking water wells or has contaminated a principal
     drinking water supply.

     It provides for:

NCP, 40 C.F.R. § 300.3 (1986) (emphasis added).    In this case, the

EPA worked with the Texas Water Commission (TWC), and a private

environmental research, or investigatory firm -- IT Corporation.

     Consistent with CERCLA, the 1986 NCP required that drinking

water supplies meet the Safe Drinking Water Act (SDWA) standards

for chromium -- a statutorily defined, "hazardous substance."     40

C.F.R. 300.68 (i), Appendix V (2).    And the NCP defined a "drinking

water supply" as "any raw or finished water source that is or may




                               -70-
                                70
be used by a public water system (as defined by the Safe Drinking

Act) or as drinking water by one or more individuals."               NCP, 40

C.F.R. § 300.6 (Definitions) (1986) (emphasis added). The 1986 NCP

also listed, as an appropriate response "to the threat of direct

contact with hazardous substances or pollutants or contaminants,"

the provision of an alternate water supply "where it will reduce

the likelihood of exposure of humans or animals to contaminated

water."        40 C.F.R. 300.65(c)(8) (emphasis added).            In short,

contrary to the majority opinion, the EPA has not been statutorily

or administratively handicapped to act only in an "all or nothing"

manner relative to threats of hazardous substance exposure; quite

the contrary.

     The majority's contentions notwithstanding, the Administrative

Record    in    fact    contains   substantial   evidence   that   the   EPA's

provision of an alternate water supply system was not arbitrary or

capricious at the time the EPA made its AWS decision.

     In accordance with the NCP's fair, established procedures, a

study was conducted to examine the alternatives available to

accomplish the task of providing safe water to those in the

affected area.         Based on this study, a determination was made that

the best option was to extend the public water supply operated by

the adjacent city of Odessa, Texas to the site.                Indeed, the

determination to provide this alternate water supply to those in




                                      -71-
                                       71
the affected area was based on an extensive Administrative Record,

including in particular a two-volume Remedial Investigation report

and a Record of Decision (which incorporates by reference, among

other documents, the Remedial Investigation) -- outlining the EPA's

reasons for selecting the AWS approach to the threats posed by the

chromium-contaminated, sole drinking water source, Trinity Aquifer.

     The chromium posed a threat to present and future human life

in the area.   As already stated, in making its assessments of the

situation, the government was compelled by the NCP in effect at the

time to follow the standards set in the Safe Drinking Water Act

(the "SDWA"), 42 U.S.C. § 300f et seq.          Chromium is one element for

which maximum concentration limits ("MCLs") were set under the

SDWA.   The government found twelve of the fifteen sample wells

tested had chromium levels at or above the MCL for chromium.

Further,   nine    of   these   twelve    met    or   exceeded   the   higher

recommended MCLs for chromium proposed by the EPA in the Federal

Register of November 13, 1985.     Administrative Record at 3146.         And

the Remedial Investigation "determined that about thirty (30)

people were presently being served by seven (7) wells that produce

the groundwater with chromium concentrations above the drinking

water standard."    Administrative Record at 4015.

     The Administrative Record reflects a decision "to provide the

residents and businesses in the Superfund Impacted Service Area

with an alternate water supply from the City of Odessa (City)."

("Concurrently [with the Remedial Investigation and the Feasibility

Study    for   the   site],     a    Focused         Feasibility        Study    (FFS)    was

alternate      methods   were       available        to   supply    these       people   and

surrounding potentially affected areas with a safe drinking water

source.").

      Sequa     complains       that       businesses        using        the    chromium-

contaminated wells ultimately were not "allowed" to participate in

the     alternate    water      supply         system,     and     argues       that     this

demonstrates that the decision to implement the AWS was arbitrary

and capricious. However, as already noted, and contrary to Sequa's

contention, the Administrative Record reveals that businesses were

indeed a focus of the AWS decision.                       The Administrative Record

further reflects that businesses could be incorporated into the

design and construction of the system if they bore their own

administrative costs and burdens.7         Moreover, CERCLA requires the

EPA to take measures to minimize threats to public health and the

environment,   not    to   ensure   elimination   of   all   such   threats.

Accordingly, the 1986 NCP listed, as an appropriate response "to

the   threat   of    direct   contact   with   hazardous     substances   or




       7
         The following record of communication is found in the
Administrative Record:
     It was further decided that only those who responded
     "yes" on the survey [for those interested in water at
     Odessa I and II -- of which there were 2 (owning 8 lots)
     out of ten, and 56 out of 56 residents contacted,
     respectively)] would be given the opportunity to sign a
     contract for water.    * * *   Businesses and those who
     responded "no" on the questionnaire are not being
     considered for contact again. These residents can be
     incorporated into the design and construction of the
     system if they do their own platwork -- obtaining plat
     information and get their contracts notarized [sic]. The
     businesses must do their own negotiations with the city,
     and they incur all expenses for construction.
Administrative Record at 4068 (Record of Communication to the EPA
from the Texas Water Commission, regarding a discussion of the
Record of Decision for Phase 2 of the Odessa AWS design; dated
8/19/87).
     In its footnoted "majority dissent," the majority has
misconstrued my citation of the 1987 Record of Communication as an
attempt to rely upon an "event" occurring subsequent to the EPA's
initial AWS decision to support that decision. Actually, I have
cited the 1987 Record of Communication simply to refute the
majority's misguided, post hoc assertion on Sequa's behalf that the
AWS decision must be "arbitrary and capricious" because businesses
in the area were not "allowed" to participate in the AWS. The 1987
Record of Communication in fact reflects that the official decision
to impose an entitlement regime upon area businesses regarding
their ability to participate in the AWS -- i.e., only if the
businesses do their own platwork and do their own negotiations with
the city and incur their own expenses for construction -- was made
after the initial decision to provide the AWS to the area
generally.

humans or animals to contaminated water."          40 C.F.R. 300.65(c)(8)

(1986) (emphasis added).      It is obvious that the AWS provided to

the area (an area otherwise dependent upon a chromium-contaminated

aquifer for its sole source of drinking water) (at least) minimized

the likelihood, present and future, of exposure of humans and

animals to the contaminated water.8

      In sum:   the majority has erred in substituting its own, post

hoc vision of wise response action judgment for that of the agency.

The   EPA's   determination   to   install   the   AWS   is   the   type   of

technically expert decision to which this Court properly accords

"great deference."     The agency's interpretations of its broad

CERCLA directives were reasonable.           The Administrative Record

supports the agency's particular AWS determination. And the agency

determination is not inconsistent with the NCP.          We should uphold

the district court's decision to grant summary judgment to the

agency on the questions associated with the executive agency

decision to provide an alternate water supply to the individuals

residing in the chromium-affected area.       To so uphold the agency's

      8
       In light of the fact that the statutory and administrative
regime does not handicap the EPA to act in response to health and
environmental threats merely in an "all or nothing" manner, I am
unable to fathom the majority's dissenting point in its footnote 21
-- to the effect that I have "not explained how any potential
threats to the public health were minimized by the alternate water
supply system, when the EPA did not require residents to connect to
the new system and did not prohibit them from using contaminated
water from their wells." The bemoaning of the fact that an agency
did not use more of its enforcement and regulatory power strikes me
as a strange argument to be made in the course of criticizing the
very use of agency enforcement and regulatory power.

decisionmaking and action does not amount to "meek deference" to

the EPA's scientific expertise, as the majority has asserted.

However, the scrutiny to which the majority subjects the agency's

AWS decision certainly amounts to much more than the appropriate

deferential review of the agency's action called for under the

Supreme Court's caselaw concerning agency implementation of federal

statutes.    See e.g., Chevron, U.S.A., Inc. v. Natural Resources

Defense, 467 U.S. 837 (1984).

                          All Costs?   Yes.

     I think we should decide whether the EPA is entitled to

recover all of its costs for designing and constructing the AWS.

We should decide that it is.

     As the majority has stated, CERCLA § 107 provides for the

recovery of the following costs:

                  (A)   all costs of removal or remedial
            action    incurred  by   the  United  States
            Government or a State or an Indian tribe not
            inconsistent with the national contingency
            plan;

                 (B) any other necessary costs incurred
            by any other person consistent with the
            national contingency plan;

                 (C) damages for injury to, destruction
            of, or loss of natural resources, including
            the reasonable costs of assessing such injury,
            destruction, or loss resulting from such a
            release; and

                 (D) the costs of any health assessment
            or health effects study carried out under
            section 9604(i) of this title.

                                 77
42 U.S.C. § 9607(a)(4) (emphasis added).                 I share the majority's

serious doubt that Congress intended to give the EPA completely

unrestrained        spending     discretion.       But   we      are    bound    to   pay

attention      to   the   fact    that,   while    CERCLA's       §    6307   (a)(4)(A)

provides that the United States is entitled to recover "all costs

of   removal    or    remedial     action   incurred       by    the    United   States

Government or a State or an Indian tribe not inconsistent with the

national contingency plan," other provisions of the statute --

dealing with recovery of costs by private parties under CERCLA --

state that these private parties are entitled to recover only

"reasonable costs" of certain activities.                   See 42 U.S.C. § 9607

(a)(4)(B).

      We must presume that when Congress wants to make cost a factor

of statutory analysis it knows how to do so.                     See e.g., Union of

Concerned      Scientists        v.   United      States        Nuclear       Regulatory

Commission, 824 F.2d 108, 115 (D.C. Cir. 1987), and cases cited

therein.9    Were we to ascribe no meaning to the distinctions drawn

in CERCLA's § 9607, we would be derelict in our duty to pay close

heed to both what Congress has said and what Congress has not said



      9
       An example is close at hand. CERCLA requires that remedial
(permanent) actions be cost-effective; however, there is no
corresponding requirement with respect to removal (interim)
actions. 42 U.S.C. § 9621(b). (The NCP implements the remedial
action, cost-effectiveness statutory directive by requiring the EPA
to consider cost with respect to any remedial alternative, and to
select only a cost-effective remedial measure. See Hardage, 982
F.2d at 1443.)

in the statute under review.        We would be derelict in our duty to

interpret the law as plainly written by Congress.

     I   note   also   that   the   congressional   intent   reflected   in

CERCLA's § 9607's "all costs" language reasonably reflects a

fundamental purpose of CERCLA -- to ensure that there be rapid

recovery of response costs from polluters, which in turn ensures

that the Superfund will be made whole quickly and that the funds

recovered can be applied to still other hazardous sites.          As the

Second Circuit explained recently:

       In passing CERCLA Congress faced the unenviable choice
     of enacting a legislative scheme that would be somewhat
     unfair to generators of hazardous substances or one that
     would unfairly burden the taxpaying public.          The
     financial burdens of toxic clean-up had been vastly
     underestimated -- in 1980 when CERCLA was enacted $1.8
     billion was thought to be enough.      In 1986 when the
     Superfund Amendments and Reauthorization Act of 1986
     (SARA), Pub. L. No. 99-499, 100 Stat. 1613 (1986), was
     passed, $100 billion was held to be needed. It may well
     be more today. It is of course the public-at-large that
     is already bearing the economic brunt of this enormous
     national problem.

United States v. Alcan Aluminum Corp., 990 F.2d 711, 716-717 (2nd

Cir. 1993).

     Sequa has failed to show that the EPA's AWS action in this

case was inconsistent with the NCP guiding EPA responses at the

time of the agency's AWS decision and action.         Thus, in this case

at least, Sequa's "reasonable cost" argument must fail. See United

States v. Northeastern Pharmaceutical, 810 F.2d 726, 747-748 (8th

Cir. 1986) (noting that CERCLA's § 9607(a)(4)(A) does not refer to

all reasonable costs, but simply to all costs, and concluding




                                    -79-
                                     79
therefore that all costs incurred by the government that are not

inconsistent      with   the   NCP   are       conclusively   presumed    to   be

reasonable), cert. denied, 484 U.S. 848 (1987); United States v.

Hardage, 982 F.2d 1436, 1443 (10th Cir. 1992) ("[a]s long as the

government's choice of response action is not inconsistent with the

NCP,    its    costs   are   presumed    to    be   reasonable   and   therefore

recoverable.").

       Finally, I cannot join in the majority's commensuration with

Sequa over the imagined "horrible" of unbounded liability for

response costs assertedly effectuated by the district court's

ruling.       As the Second Circuit discussed in Alcan Aluminum Corp.,

Congress and the courts have constructed a framework of fairness to

avoid the majority's feared "lack of limits" to the scope of CERCLA

liability.       See United States v. Alcan Aluminum Corp., 990 F.2d

711, 721-722 (2nd Cir. 1993).10               The majority nonetheless finds

particularly frightening Sequa's hypothetical in which the EPA

enters into an independent contract with someone to investigate and

respond to hazardous waste possibilities, and then collects from

the defendant polluters, as among the costs of this response, a

Rolls Royce to be provided to the independent contractor as a perk

for the latter's good labors. Yet, the majority's fears are simply




       10
       The defendant's opportunity to demonstrate that reasonable
apportionment is possible is part of this framework. So is the
statutory availability of equitable contribution.




                                        -80-
                                         80
unfounded.   The legal reality is that this sort of grossly-

attenuated "horrible" cannot come to pass.    As the United States

Supreme Court put it, in a similar context:




                              -81-
                               81
     There are obviously discretionary acts performed by a
     Government agent that are within the scope of his
     employment but not within the discretionary function
     exception [to the Federal Tort Claims Act] because these
     acts cannot be said to be based on the purposes that the
     regulatory regime seeks to accomplish. If one of the
     officials involved in this case drove an automobile on a
     mission   connected  with   his   official  duties   and
     negligently collided with another car, the exception
     would not apply. Although driving requires the constant
     exercise of discretion, the official's decisions in
     exercising that discretion can hardly be said to be
     grounded in regulatory policy.

United States v. Gaubert, -- U.S. --, --, 111 S.Ct. 1267, 1275 n.7

(1991)   (emphasis   added).   Thus,   there   exist   well-established

standards whereby the majority's imagined Rolls Royce "horrible"

would surely be adjudged arbitrary and capricious.            In stark

contrast to the Rolls Royce "horrible" constructed by Sequa and the

majority, the EPA response action at issue in this case -- as

reflected in the Administrative Record -- is well grounded in

CERCLA regulatory policy, not to mention the plain language of the

statute, and is not arbitrary and capricious.

                                 IV

                          Settlement Credit

     Finally, I do not think the district court erred in crediting

the consent decree proceeds toward reimbursing the government for

the costs incurred in pursuing Bell through bankruptcy proceedings,

before allowing the leftover proceeds from the Bell settlement to

be credited toward the sum Sequa was left owing the government.




                                -82-
                                 82
Sequa's interpretation of 42 U.S.C. § 9613 (f)(2) is unduly narrow

and unreasonably strained.11

     First, reimbursable "response costs" made the subject of the

Bell consent decree are specifically defined in the consent decree,

as including enforcement expenses -- including in particular,

attorneys' fees. And such expenses are recoverable under CERCLA --

at least in response cost recovery cases brought by the government.

See e.g., United States v. Northernaire Plating Co., 685 F. Supp.

1410, 1418 (W.D. Mich. 1988) (recoverable costs include "attorney

fees and litigation expenses incurred by the staffs of the EPA and

the Department of Justice"), aff'd sub nom. United States v. R. W.

Meyer Inc., 889 F.2d 1497 (6th Cir.), cert. denied, 494 U.S. 1057

(1990); United States v. Northeastern Pharmaceutical, 579 F. Supp.

823, 851-852 (W.D.Mo. 1984) (to the same effect), aff'd in part,

rev'd in part on other grounds, 810 F.2d 726 (8th Cir. 1986), cert.

    11
       42 U.S.C. § 9613, as amended by the 1986, SARA amendments,
provides:
     (f) Contribution
        (2) Settlement
              A person who has resolved its liability to
          the    United  States   or   a   State  in   an
          administrative     or    judicially    approved
          settlement shall not be liable for claims for
          contribution regarding matters addressed in
          the settlement.     Such settlement does not
          discharge any of the other potentially liable
          persons unless its terms so provide, but it
          reduces the potential liability of the others
          by the amount of the settlement.




                               -83-

Lohrey Enterprises, 984 F.2d 1015 (9th Cir. 1993) (holding that

private parties are not entitled to recover attorneys' fees and

expenses as costs incurred in bringing CERCLA cleanup cost recovery

action), with General Electric Co. v. Litton Industrial Automation

Systems, Inc., 920 F.2d 1415 (8th Cir. 1990) (holding that private

parties are entitled to recover attorneys' fees and expenses

incurred in bringing CERCLA cleanup cost recovery action), cert.

denied, -- U.S. --, 111 S.Ct. 1390 (1991).

      Moreover, the purpose of the CERCLA § 113(f)(2) settlement

offset provision is to prevent the government from obtaining

"double recoveries" in cases in which joint and several liability

has   been     imposed.         See     United    States      v.        Northeastern

Pharmaceutical, 810 F.2d 726, 748-749 (8th Cir. 1986) ("Appellants

argue that unless the judgment is offset by the amount of the

Syntex settlement, the government will improperly receive a double

recovery of that amount from Syntax and the appellants."), cert.

denied, 484 U.S. 848 (1987).          The district court's treatment of the

consent decree proceeds is fully consistent with this anti-double

recovery purpose.        The district court's ruling, that the initial

crediting of the Bell settlement funds must go toward making the

government whole with respect to the enforcement expenses it

incurred     in    connection    with     pursuing     Bell        in    bankruptcy

proceedings,      does   not   provide    the    government    with       a   "double

recovery."     Indeed, an adoption of Sequa's view of the crediting

provision would provide Sequa with a "windfall" at the expense of




                                       -84-
                                        84
the Superfund. In short, the result advocated by Sequa is contrary

to the most fundamental purposes of CERCLA.

     In my opinion, Sequa should be provided its statutory right of

equitable response cost allocation under 42 U.S.C. § 9613 (f)(1).

My approach approves the district court's alternate, equitable

"appropriation"   as   a    §   9613    (f)(1),   equitable   response   cost

allocation.   Under my approach, Sequa would be responsible for its

35% share of cost responsibility, and no more -- notwithstanding

the settlement the government has negotiated with Bell.             If that

amount would, absent a crediting from the settlement proceeds,

result in the government reaping a "double recovery," then the

crediting provision should be applied to prevent that result.              In

such circumstances, the money remaining from the Bell settlement

after the application of some of it toward the reimbursement of the

government for its enforcement expenses incurred against Bell in

bankruptcy proceedings may be credited to the joint and several

liability of Sequa.        If, on the other hand, the combination of

Sequa's equitable allocation of response costs payment plus the

leftover settlement (crediting) proceeds still fails to make the

Superfund whole, it is my opinion that such is simply the proper

consequence of the bargain the government struck in this case; the

government must live with its bargain.

     While I concur with much of the majority opinion, I must also

dissent from much of it.          Contrary to congressional intent and

traditional judicial doctrines -- not to mention the bedrock

principle of a prudent separation of federal governmental powers --

the majority has become much more than an appellate court in order

to   reach   its   rulings   in    this    case   regarding   quantitative

apportionment and the executive branch decision to provide the

chromium-affected area with an alternate water supply system.          The

majority has usurped for itself the special powers of the executive

agency and the trial court as well.
