UNITED STATES of America, Plaintiff-Appellee,

v.

Ralph L. LOWE, et al., Defendants,

Dow Chemical Company USA; Merichem Company; Monsanto Company;

Mobil Chemical Company; Arco Chemical Company; Petro-Tex Chemical

Corporation; Rohm & Haas Company, Defendants-Appellants.

July 31, 1997.

Appeal f rom the United States District Court for the Southern

District of Texas.

Before DAVIS, STEWART and PARKER, Circuit Judges.

PARKER, Circuit Judge:

The appellants present to this court the issue of whether the

government may recover costs e xpended in overseeing a hazardous

waste cleanup that was conducted by private parties. The district

court granted the gover nment summary judgment on this issue,

finding that such costs are recoverable by the government. For the

following reasons, we affirm.

FACTS AND PROCEEDINGS BELOW

This case arose in conjunction with the Dixie Oil Processors

Superfund site located near Friendswood in Harris County, Texas.

Pursuant to an order issued by the Environmental Protection Agency

("EPA") under § 106 of CERCLA, 42 U.S.C. § 9606, the appellants

conducted a cleanup of the site that was certified as complete by

the EPA in April 1993.

In 1991 the government filed a cost recovery action to recover1 The appellants do not appeal the government's oversight costs

related to a Remedial Investigation/Feasibility Study ("RI/FS")

which is a study condu cted in the initial phases of a Superfund

site cleanup to determine the nature and extent of contamination,

evaluate the risk to the public and the environment, and identify

p otential methods to clean up or adequately manage the

contamination.

2 its response costs purs uant to CERCLA § 107(a), including its

oversight costs, and for a de claratory judgment of liability for

future response costs. The complaint requested all costs incurred

by the government that were related to removal or remedial action.

The government moved for summary judgment in February 1994. The

defendant-appellants responded that CERCLA di d not authorize the

government to recover costs for oversight of their performance of

clean-up work. The district court granted summary judgment to the

government. U

nited States v. Lowe, 864 F.Supp. 628 (S.D.Tex.1994).

The appellants now appeal to this court the district court's

judgment relating to EPA oversight costs. 1

DISCUSSION

This appeal is taken from the district court's order granting

summary judgment on the basis of its interpretation of a federal

statute. We review such d e novo. Estate of Bonner v. United

States, 84 F.3d 196, 197 (5th Cir.1996). The appellants contend

that the district court erred in ruling that the government was

entitled to reimbursement of its costs incurred in oversight of the

private party clean-up of the site. They argue that the oversight

costs are not costs for which they can be held liable under §

107(a) of CERCLA. We disagree.

A.2 Rohm and Haas, and its reliance on National Cable,

represented a signific ant departure from prior case law. For

example, when addressing government oversight o f a private party

3 The appellants urge that we follow the Third Circuit's

reliance on the "clear statem ent" doctrine expounded in National

Cable Television Ass'n, Inc. v. United States, 415 U.S. 336, 94

S.Ct. 1146, 39 L.Ed.2d 370 (1974), when that circuit addressed the

very same issue and held that the government could not recover

oversight costs for a private party clean-up. S ee United States v.

Rohm and Haas Co., 2 F.3d 1265 (3rd Cir.1993). Under N ational

Cable, Congress must "clearly state" its intent to impose

particular fees on regulated industries in connection with

lic ensing or permitting in order to exact such fees

constitutionally within its taxing authority. The appellants

contend that National Cable 's "clear statement" requirement should

be applied to CERCLA because the administration of hazardous waste

clean-up benefits the general public, and the assessment of fees on

specific parties for the payment for benefits to the general public

endows that fee with the characte r of a tax assessment. The

appellants go on to argue that as a d e facto tax payment,

re imbursement of government oversight costs for a private party

clean-up is impermissible under National Cable absent language in

the statute indicating a clear intent that the EPA have the

authority to recover such oversight costs.

We agree with the government and find the interjection of the

National Cable doctrine inappropriate to our consideration of this

issue of reimbursement of oversight costs. 2 National Cable and itscleanup, th e Second Circuit had held that the state government's

costs in assessing the conditions of a site and in supervising

removal of the waste by a private party "squarely fall within

CERCLA's definition of response costs, even though the State is not

undertaking to do t he removal." N ew York v. Shore Realty Corp.,

759 F.2d 1032, 1043 (2d Cir.1985). A number of courts had

previously held that under CERCLA § 107, the EPA can recover

administrative and indirect costs a ssociated with a government

cleanup. S ee, e.g., United States v. Ottati & Goss, Inc., 900 F.2d

429, 444 (1st Cir.1990); U nited States v. R.W. Meyer, Inc., 889

F.2d 1497, 1504 (6th Cir.1989); K elley v. Thomas Solvent Co., 790

F.Supp. 719, 729 (W.D.Mich.1990); U nited States v. Hardage, 733

F.Supp. 1424, 1438-39 (W.D.Okla.1989), aff'd. in part and rev'd in

part on other grounds, 982 F.2d 1436 (10th Cir.1992).

In rejecting Rohm and Haas, we are in good company. See

Atlantic Richfield Co. v. Am. Airlines, Inc., 98 F.3d 564

(10th Cir.1996); P neumo Abex Corp. v. Bessemer and Lake Erie

R.R. Co., Inc., 936 F.Supp. 1250, 1262-63 (E.D.Va.1996); T own

of New Windsor v. Tesa Tuck, Inc., 935 F.Supp. 317, 324-27

(S.D.N.Y.1996); C alifornia v. Celtor Chem. Corp., 901 F.Supp.

1481, 1489-90 (N.D.Cal.1995); United States v. Ekotek, Inc.,

1995 WL 580079, at *4-*5 (D.Utah 1995); Cal. Dep't of Toxic

Substances Control v. SnyderGeneral Corp., 876 F.Supp. 222,

225 (E.D.Cal.1994).

3 In National Cable, the Supreme Court held that a federal

executive agency assessment which recoups the costs of overseeing

a regulated industry constitutes a federal tax to the extent that

it exceeds the value of the benefit of regulation to the regulated

group, and that under the separation of pow ers doctrine, the

federal government cannot collect such a tax unless Congr ess's

intent to delegate to t he executive branch the discretionary

authority to recover such a tax is clearly exp ressed. 415 U.S.

336, 94 S.Ct. 1146, 39 L.Ed.2d 370.

4 progeny concern the imposition of user fees on regulated entities

seeking authorization to do business. 3 S ee Miss. Power & Light Co.

v. U.S. Nuclear Regulatory Comm'n, 601 F.2d 223, 227 (5th

Cir.1979). CERCLA does not assess user charges on a regulated

industry; rather, it is a remedial statute, see United States v.

R.W. Meyer, 889 F.2d 1497, 1504 (6th Cir.1989). CERCLA response

costs are neither fees nor taxes, but rather, payments by liable

parties in the nature of restitution for the costs of cleaning up5

a contamination or a threatened contamination for which t hey are

responsible. Atlantic Richfield Co. v. Am. Airlines, 98 F.3d 564,

568 (10th Cir.1996); U nited States v. Monsanto Co., 858 F.2d 160,

174-75 (4th Cir.1988); C ontinental Ins. Cos. v. Northeastern

Pharm. & Chem. Co., Inc., 842 F.2d 977 (8th Cir.1988); M d. Cas.

Co. v. Armco, Inc., 822 F.2d 1348, 1352 (4th Cir.1987); United

States v. Northeastern Pharm. & Chem. Co., Inc., 810 F.2d 726, 749

(8th Cir.1986 ); Town of New Windsor v. Tesa Tuck, Inc., 935

F.Supp. 317, 326 (S.D.N.Y.1996). As the Ninth Circuit explained,

the Supreme Court did not announce universal definitions of a "tax"

or "fee" in National Cable, but merely determined the meaning of

the terms of the statute at issue. U nion Pacific R.R. Co. v.

Public Utility Comm'n, 899 F.2d 854, 859-61 (9th Cir.1990).

B.

Under CERCLA, the government may eithe r conduct clean-ups

itself or permit or require responsible parties to do so. CERCLA

§§ 104(a) and 106, 42 U.S.C. §§ 9604(a) and 9606. Liability for

costs incurred by the government or a private party in cleaning up

a site is imposed by CERCLA § 107(a)(4), 42 U.S.C. § 9607(a)(4),

which provides that responsible parties are liable for "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 cont ingency plan" and "any other necessary costs of

response incurred by any other person consistent with the national

contingency plan." In other words, if the government's actions are

response actions in harmony with the national contingency plan,6

then costs incurred pursuant to those actions are recoverable from

liable parties. U nited States v. Hardage, 982 F.2d 1436, 1441

(10th Ci r.1992). The question presented is whether the

government's oversight costs in a res ponsible party clean-up are

response costs under CERCLA.

CERCLA § 101 defines the terms "response," "remova l," and

"remedial action." Responses consist of removals and remedial

actions an d "enforcement activities related thereto." CERCLA §

101(25), 42 U.S.C. § 9601(25). A "removal" is generally understood

to be a short-term response and a "remedial action" is generally

considered a long-term response or permanent solution. See CERCLA

§ 101(23) & (24), 42 U.S.C. § 9601(23) & (24); Daigle v. Shell Oil

Co., 972 F.2d 1527, 1533-34 (10th Cir.1992). Removal is defined

broadly, as follows.

[T]he cleanup or removal of released hazardous substances from

the environment, such actions as may be necessary taken in the

event of a threat of release of hazardous substances into the

environment, such actions as may be necessary to moni tor,

assess, and evaluate the releas e 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 t he environment, which may otherwise result from a

release or threat of release.

CERCLA § 101(23), 42 U.S.C. § 9601(23) (emphasis added). "Remedial

action" is also defined broadly and includes

those actions consistent with permanent remedy taken instead

of or in addition to removal actions in the event of a release

of threatened 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 and associated and7

associated contaminated materials, recycling or reuse,

diversion, destruction, segregation of reactive wastes,

degrading or excavations, repair or replacement of leaking

containers, collections of leachate and runoff, onsite

treatment or incineration, provision of alternative water

supplies, and any monitoring reasonably require d to assure

that such actions pro tect the public health and welfare and

the environment.

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

C.

"Monitoring" is a term used in the definitions of both

removal and remedial action. It is not defined in CERCLA. A term

not defined in a statute must be construed in accordance with its

ordinary and natural meaning, United States v. Alvarez-Sanchez, 511

U.S. 350, 357, 114 S.Ct. 1599, 1603, 128 L.Ed .2d 319 (1994), as

well as the overall policies and objectives of the statute, Brown

v. Gardner, 513 U.S. 115, 117-19, 115 S.Ct. 552, 555, 130 L.Ed.2d

462 (1994). I n re Locklin, 101 F.3d 435, 439 (5th Cir.1996).

Unless an application of the tradit ional principles of statutory

construction reveals the plain language to be ambiguous, i .e.,

susceptible to more than one reasonable interpretation, our inquiry

ends as we must give effect to Congress's unambiguously expressed

intent. R eich v. Arcadian Corp., 110 F.3d 1192, 1195 (5th

Cir.1997). As suggested above, the plain meaning of a word cannot

be determined in isolation, but must be drawn from the context in

which it is used. Id. a t 1195-96. Given such a rule of statutory

construction, a term is not considered ambiguous even though it may

be susceptible to different interpretations when the context

eliminates all but one of the meanings. Id. at 1196.

The verb "monitor" is generally synonymous with audit, check,8

control, inspect, investigate, observe, oversee, regulate, review,

scrutinize, study, survey, test and watch. S ee William C. Burton,

Legal Thesaurus 337 cited in Atlantic Richfield Co., 98 F.3d at

569; Webster's Third Internat'l Dictionary 1460 (Philip B. Gove,

ed.1993) cited in Atlantic Richfield Co., 98 F.3d at 569; s ee also

Am. Heritage Dictionary 848 (William Morris, ed.1970) ("to

scrutinize or check systematicall y with a view to collecting

certain specified categories of data" and "to keep watch over;

supervise").

The term removal is aimed at containing and cleaning up

hazardous substance releases. S e e United States v. Hardage, 982

F.2d 1436, 1448 (10th Cir.1992). Under a plain language statutory

reading with an eye to context, the monitoring provided for under

the "removal" definition relates to an evaluation of the extent of

a "release or thr eat of a release of hazardous substances." 42

U.S.C. § 9601(23); D aigle, 972 F.2d at 1535. "Removal" action

also includes those activities that are deemed necessary to prevent

hazardous releases from adversely affecting the public health. See

Hanford Downwinders Coalition, Inc. v. Dowdle, 71 F.3d 1469, 1477

(9th Cir.1995). It is unquestioned that EPA oversight is a

necessary part of the removal process and ensuring compliance with

standards aimed at the public health. Thus, the term removal

action includes the monitoring conducted by the EPA via its

oversight activities.

The "remedial action" definition expressly focuses on actions

n ecessary to "prevent or minimize the release of hazardous9

substances so that they do not migrate to cause substantial danger

to present or future public health or welfare or the environment,"

42 U.S.C. § 9601(24); P rice v. U.S. Navy, 39 F.3d 10 11 (9th

Cir.1994), and so we read the term's inclusion of "such actions as

may be necessary to monitor, assess, and evaluate the release or

threat of release of hazardous substances," with such in mind. EPA

oversight, or monitoring, is certainly part and parcel of

preventing and minimizing the r elease of hazardous substances.

Government oversight of private party remedial actions ensures that

remedial actions will be effective in preventing or minimizing past

or threatened releases, the essence of the definition of remedial

action. See CERCLA § 101(24); Atlantic Richfield Co., 98 F.3d at

569 ; cf. Daigle v. Shell Oil Co., 972 F.2d 1527, 1535 (10th

Cir.1992) (ho lding that CERCLA § 101(24)'s "monitoring" does not

include medical monitoring of persons exposed to hazardous

substances because th at monitoring did not prevent or minimize a

release or threatened release per CERCLA's definition of "remedial

action").

In addition, response actions, which include both remedial and

response actions, are defined to incl ude "enforcement activities

related thereto." CERCLA § 101(25), 42 U.S.C. § 9601(25). EPA

oversight of removal and remedial actions that are conducted by

responsible parties easily falls within this definition of

response. As the district court explained, the EPA must evaluate

all stag es of the cleanup process, from the preliminary

investigation through the final disposition of hazardous substances10

at a site. L owe, 864 F.Supp. at 631. Government monitoring or

oversight is an inherent and necessary enforcement element of

private party respons e action. CERCLA § 111(c)(8) clearly

contemplates that the government must monitor pr ivate party

remedial actions and CERCLA § 122(f)(3) and (5) require government

monitoring of private party remedial actions. In the same vein,

CERCLA § 122(a), 42 U.S.C. 9622(a), authorizes the EPA to settle

with liable parties to perform response actions "if [EPA]

determines that such action will be done properly." To meet those

obligations, § 106(a) orders and consent decrees typically require

that responsible parties meet performance standards, that the EPA

conduct periodic reviews to determine that work meets the

sta n dards, that the EPA determine whether additional response

actions are necessary, and that the EPA certify that a clean-up has

been performed as required. S ee 42 U.S.C. § 9621; 40 C.F.R. §

1.47. Thus, government monitoring or oversight reasonably required

to assure that private party actions protect the public health and

we lfare and the environment also qualifies as response activity

under the "enforcement activities " component of the response

definition. A tlantic Richfield Co., 98 F.3d at 570 ("determin[ing]

whether the action complies with a consent decree and the

provisions of CERCLA is enforcement activity related to a remedial

action, and therefore, is a response under § 101(25)"); s ee also,

e.g., 56 Fed.Reg. 30,996, 30,998 (July 8, 1991) (model consent

decree for § 122 settlements requiring settling defendants to pay

all response costs incurred by government including "reviewing or4 Costs involved in the oversight of a private party clean-up

are most assuredly not general administrative costs incurred by an

administrative agency, as the appellant s attempt to characterize

them, but costs incurred in relation to the oversight of remedial

or removal action at a specific site. "EPA oversight costs are not

... to pay the EPA's general administrative costs, but part of the

damages caused or contributed to by specific pe rsons." A tlantic

11 developing plans, reports and other items" and "verifying the work,

or otherwise implementing, ov erseeing, or enforcing this consent

decree").

Finally, we note that any other reading of the statutory terms

under discussion would produce a result that conflicts with

CERCLA's goal of compelling private parties to perform clean-up

operations. S ee Ekotek, 1995 WL 580 079, at *8. In addition, an

absurd incongruity would result if we were to permit the government

to recover its costs for oversight of its own contractors, but not

recover the costs of oversight of private party contractors. There

is no basis in the statute for ma king such a distinction. Under

CERCLA, response actions may be taken either by private parties or

the government, neither § 101(24) nor § 101(23) distinguishes

between private party and government actions, and the EPA has the

authority under C ERCLA § 104(a) to conduct removal and remedial

actions if it determi nes that responsible parties have failed to

complete necessary steps.

The enforcement activities of § 101(25)'s definition of

response actio ns, the monitoring referred to in § 101(24)'s

definition of removal action and the monitoring and necessary

actions of § 101(23)'s remedial action all clearly include

gov ernment oversight. 4 EPA oversight is an integral and criticalRichfield Co., 98 F.3d at 568.

5 While the Rohm & Haas court analyzed only the definition of

removal and did not specifically discuss the definition of remedial

action, and the Atlantic Richfield court focused its analysis on

remedial action in deciding that oversight costs are response

costs, there is no meaningful distinction between remedia l and

removal actions in the context of the issue of reimbursement of EPA

oversight costs for private party clean-ups. Accordingly, our

holding encompasses both scenarios.

12 part of removal and remedial actions and of enforcing the terms of

a governing order or consent decree. We join the Tenth Circuit and

f ind that CERCLA's plain language and liability scheme authorize

the EPA's cost recovery for the oversight of private party response

actions. 5 See Atlantic Richfield Co., 98 F.3d 564.

CONCLUSION

We conclude that government monitoring or oversight of a

private party remedial or removal action is a response under CERCLA

§ 101(25). Consequently, under CERCLA § 107(a)(4)(A), the

responsible parties are liable for the costs of EPA oversight. For

the foregoing reasons, we AFFIRM the district court.
