   FINDINGS OF FACT AND CONCLUSIONS OF LAW FOR REMEDY SELECTION PHASE

PHILLIPS, District Judge.

I. INTRODUCTION

This Order arises from the trial of a bifurcated portion of a CERCLA case. The trial involved the selection of a remedy for the cleanup of toxic wastes at the Hard-age Superfund Site (“Hardage Site”), a closed industrial waste disposal site located near the town of Criner, Oklahoma. The parties have presented the Court with competing remedies.

The plaintiff United States of America advances an “excavation” remedy that seeks to remove a substantial portion of the wastes and hazardous substances from the site. A second major component of the government’s remedy involves “soil vapor extraction,” a technology developed to remove highly toxic and mobile compounds from the subsurface.

The defendants, on the other hand, advance a “containment” remedy, which is designed to pump large quantities of waste from the site, while at the same time leaving substantial volumes of hazardous substances in the subsurface. The defense theory relies on a combination of natural bedrock features and man-made hydraulic barriers to create a “bathtub” effect, which, according to the Hardage Steering Committee (“HSC”) defendants, will contain the wastes and hazardous substances that are not pumped out.

The United States estimates that its remedy will cost approximately $70 million. However, the defendants contend that the costs of the government’s proposed remedy, including major repair contingencies, operation, and maintenance, will be $150 million. On the other hand, the defendants estimate their remedy will cost approximately $54 million. The government generally agrees with this estimate. The defendants further argue that the site could have been cleaned up under a plan proposed in 1982 by the Oklahoma State Department of Health (“OSDH”) at a cost, in 1989 dollars, of $17.75 million.

The government characterizes the defense proposal as “peace in our time.” The government argues that all containment remedies fail with the only question being when. The defendants, on the other hand, portray the government’s remedy as unscientific, costly, and a product of “slavish adherence” to unsound litigation strategy. The defendants also allege that the government’s proposed remedy was a “moving target” that changed substantially as the remedy trial drew closer.

As discussed more fully below, the Court divided the entire Hardage Site litigation into four major phases: (1) a remedy selection phase; (2) a liability phase; (3) a third-party claims phase; and (4) a cost allocation phase. Because of the critical nature of the remedy disputes in the case, the Court and the parties elected to proceed first with the Remedy Phase. Although the parties’ estimates of the time necessary for trial of the Remedy Phase ranged from 52 days to several months, the Court allocated only 20 days. However, the trial was concluded in just 11 days, in part because of the streamlined procedures the Court adopted, and, in part because of the extremely high caliber of legal representation on both sides of the lawsuit.

The streamlined nonjury trial procedure involved the submission of witness affidavits in lieu of direct examination on most points. The parties were given an opportunity to present both supplemental direct examination and full cross-examination of the witnesses during trial. As ordered by the Court, the parties submitted comprehensive stipulations on undisputed matters.

The Court has reviewed and considered the testimony of all of the 45 trial witnesses. In addition, the Court has examined more than 8,000 pages of affidavits and deposition transcripts, 250 pages of stipulations, and more than 470 exhibits introduced by the parties at trial, totaling more than 150,000 pages of record.

As a result of the trial, the Court is convinced that the United States has not carried its burden of proof and has not convinced the Court of the propriety of its proposed remedy. Moreover, the Court is convinced that the HSC defendants’ proposed containment remedy is markedly superior to the government’s proposed remedy. The findings of fact and conclusions of law set forth below resolve the remedy issue in favor of the HSC defendants. In addition, this Order sets forth the Court’s rulings on the other claims and matters that were at issue in the remedy trial, including: the Consent Decree, the United States’ supplemental response cost claim, the HSC defendants’ response cost claim, and other equitable defenses asserted against the United States.

II. PARTIES AND APPEARANCES

The plaintiff was represented by the following counsel for the Remedy Phase:

John R. Barker, trial attorney Department of Justice
Anna Wolgast, trial attorney Department of Justice
Kurt Weissmuller Department of Justice
Steven Novick Department of Justice
Gary S. Guzy Department of Justice
Bruce Buckheit Department of Justice
Kalyn C. Free Department of Justice
William Merrill Department of Justice
Jon Lipshultz Department of Justice
Dianne M. Shawley Department of Justice
Jerry Schwartz Department of Justice
Charles de Saillan Environmental Protection Agency
Steven Mullins United States Attorney’s Office, Western District of Oklahoma
Thomas Curtis United States Air Force

Several groups of defendants, as well as individual defendants, participated in the Remedy Phase. The HSC defendants made an appearance to oppose the imposition of the United States’ proposed remedy, to oppose approval of the Consent Decree, and to offer their own proposed containment remedy for implementation at the Hardage Site. Earlier, the HSC defendants had stipulated to liability.

The HSC defendants include: Advance Chemical Co.; Allied-Signal, Inc.; AT & T Technologies, Inc.; Ashland Oil, Inc.; Atlantic Richfield Co.; Borg-Warner Corp.; BULL HN Information Systems, Inc. (formerly Honeywell Bull, Inc.); Exxon Corp.; Bridgestone/Firestone, Inc.; GenCorp, Inc.; Magnetic Peripherals, Inc.; Mare-mont Corp.; McDonnell Douglas Corp.; Mobil Chemical Co.; Nalco Chemical Co.; Oklahoma Gas & Electric Co.; Oklahoma Publishing Co.; Rockwell International Corp.; Texaco Refining and Marketing, Inc.; Texas Instruments, Incorporated; Uniroyal, Inc.; UOP, Inc.; Westinghouse Electric Corp.; Weyerhaeuser Co.; and Powell Sanitation Service, Inc.

Common counsel provided primary representation for the HSC in the remedy trial. Kenneth N. McKinney, Robert D. Tomlin-son, Mark Coldiron, and Dawn Northup served in this capacity. Certain other attorneys provided separate representation for individual HSC generator defendants and participated in various aspects of the trial. These corporations and their attorneys included:

Jerome T. Wolf AT & T Technologies
Carl Helmstetter AT & T Technologies
Allan Gates Oklahoma Publishing Co.
Jeffrey N. Martin Oklahoma Gas & Electric Co.
James C. Morriss Bridgestone/Firestone, Inc.
Stephen Fink Bridgestone/Firestone Tire & Rubber Company
Walter J. Hryszko Exxon Corporation
Michael D. Graves Honeywell, Magnetic Peripherals, and McDonnell Douglas Corp.
Howard Seitzman Borg Warner Corp., Texas Instruments, Incorporated
Charles W. Shipley Atlantic Richfield Co., Ashland Chemical Co., and Maremount Co.
Amanda G. Birrell Nalco Chemical Co.

Other defendants and third-party defendants appeared through the following counsel:

Steve McKinney Oklahoma National Stock Yards Co.
Gavin Mclnnis Ralph L. Lowe
John D. White JOC Oil Exploration Co., Inc.
Ross Plourde Double-Eagle Refining Co.

As reflected by the trial record, participation at trial by counsel for the other defendants and the third-party defendants was minimal. Virtually all of the examination was conducted by common counsel for the HSC defendants.

Another group of defendants who participated in the Remedy Phase consisted of the consent decree defendants. These are the defendants who, on the eve of trial, entered into a Consent Decree with the United States. Under the provisions of the Consent Decree filed on November 21, 1989, the consent decree defendants agreed to pay for, and to perform, certain elements of the United States’ desired remedy for the Hardage Site. The consent decree defendants who made appearances to support the government’s proposed remedy and to advocate the approval of the Consent Decree, and their counsel, included:

Andy Coats Cato Oil and Grease Co., Kerr-McGee Refining Corp.
Leanne Burnett Kerr-McGee
Jeanie McLemore L & S Bearing Co.
Joseph F. Guida L & S Bearing Co., and Rotex Corp.
Steve LeSatz United States Pollution Control, Inc.
Irwin Steinhorn United States Pollution Control, Inc.

All counsel are to be complimented on their professionalism throughout the trial as well as during the other aspects of this case. With minor exceptions, each attorney’s in-court appearances and written submissions exhibited an exceptionally high level of preparation, a good grasp of the legal issues, submission of the most current legal and statutory authority, and respect for of the Court and fellow attorneys. Just as the Court inherited this litigation from another judge of this district, a number of the attorneys who participated in the trial inherited the case from others. As a result of the professionalism and spirit of cooperation, the case was tried quickly and thoroughly.

V. ADDITIONAL PROCEDURAL HISTORY AND BACKGROUND

A. Site Location and Operating History

Defendant Royal N. Hardage owned and operated a waste disposal site located in rural McClain County, Oklahoma, approximately 15 miles southwest of Norman and one-half of a mile west of Criner. The Oklahoma State Department of Health (“OSDH”) permitted the Hardage/Criner site as an Industrial Hazardous Waste Land Disposal Facility in September 1972. The site began operating in September 1972 and closed in November 1980.

Over the eight-year period of operation, in excess of 20 million gallons of waste were transported to the Hardage Site for storage and/or disposal. Supplemental Joint Statement of Uncontested Facts para. 48 (Nov. 21, 1989) (filing No. 2212). Originally, liquids and sludges from drums and tank trucks were discharged directly into unlined pits. As disposal areas filled, wastes were transferred to other areas. Later, drums were no longer emptied, but piled into what became the drum or barrel mound. Ultimately, the site consisted of chemical impoundments including the large unlined, unsealed “main pit,” a series of small temporary pits, and two large mounds (“barrel” and “sludge” mounds). The types of waste generally accepted at the site included: oil recycling wastes, acids, caustics, lead, cyanide, arsenic, pesticides, PCBs, and other substances. The Record of Decision (“ROD”) describes in detail other types of wastes accepted at the site, along with the hazardous contaminants present at the site. Id. at 3.2.

B. Enforcement History

In 1978, the State of Oklahoma filed complaints against the facility for suspected lead poisoning of the air around the site. In September 1979, the OSDH began proceedings to revoke the facility permit as a result of Mr. Hardage’s use of unpermitted pits, his failure to seal permeable lenses in the pits, his improper closure of pits, his failure to retain runoff, and his improper storage of wastes at the site.

During 1979, preliminary Environmental Protection Agency (“EPA”) investigations and inspections of the site indicated poor waste management practices posing threats to public health and welfare and the environment. In September 1980, the United States Department of Justice (“DOJ”) filed suit in United States v. Hardage on behalf of the EPA against Mr. Hardage, the site owner. The complaint alleged violations of section 7003 of the Resource Conservation and Recovery Act (“RCRA”), 42 U.S.C. § 6973, and sought injunctive relief for proper cleanup and closure of the site. Following the passage of CERCLA, the United States amended its complaint in June 1982 to add claims for injunctive relief under section 106 of CERCLA, 42 U.S.C. § 9606, and for cost recovery under section 107, 42 U.S.C. § 9607.

The Court bifurcated the trial in Hard-age I to consider Mr. Hardage’s liability first, and then to determine the proper remedy and costs incurred or to be incurred in any cleanup. On December 13, 1982, United States District Judge Lee R. West entered his findings of fact and conclusions of law in Hardage I. The Court found contamination of soil and groundwater as well as releases of contaminants into the air. The Court concluded that the Hardage Site was dangerous and found Mr. Hardage individually liable under section 7003 of RCRA and section 106 of CERCLA. However, because the remedial phase of the trial remained, the Court entered no judgment on the injunctive claims. United States v. Hardage, 18 Env’t Rep. Cas. (BNA) 1687, 1696 (W.D.Okla.1982). On August 19, 1983, the Court entered a partial judgment under section 107 of CERCLA against Mr. Hardage for $211,-795, which represented the United States’ response costs incurred through December 1982. The United States thereafter sought to identify Mr. Hardage’s assets and to obtain payment under the partial judgment. However, Mr. Hardage filed for bankruptcy on January 28, 1985, in the Bankruptcy Court for the Western District of Oklahoma, and received a discharge in bankruptcy on June 24, 1985.

After the Court’s liability ruling in Hard-age /, the EPA continued to study the Hardage Site through investigations and administrative review. The EPA prepared a feasibility study to evaluate alternative remedial actions to clean up the Hardage Site from technical, environmental, and cost-effective perspectives. The EPA conducted studies of the Hardage Site in 1982, 1983, and 1984. The studies concluded that substantial work would be necessary to clean up the Hardage Site. In addition, the United States sought to identify other parties responsible for the contamination, in light of Mr. Hardage’s financial difficulties.

As the EPA compiled available records from site operations, numerous Potentially Responsible Parties (“PRPs”) were identified. In December 1984 the EPA notified numerous companies, pursuant to section 104 of CERCLA, 42 U.S.C. § 9604, of their status ás PRPs pursuant to section 107 of CERCLA, 42 U.S.C. § 9607.

Following Mr. Hardage’s discharge in bankruptcy, the United States requested, and the Court on July 18, 1985, issued, an order administratively terminating Hard-age I. The administrative closing was ordered without prejudice to the rights of the parties to reopen the proceedings by April 1, 1986, “for good cause shown, for entry of any stipulation or order, or for any other purpose required to obtain a final determination of the litigation.” On March 27, 1986, the United States moved to reopen the proceedings and to amend its complaint in Hardage I. The United States sought to add as party defendants various generators and transporters of the hazardous substances located at the Hardage Site. The Court denied the United States’ motion and dismissed the case on April 1, 1986. The dismissal was without prejudice to the United States’ rights to collect the earlier judgment against Mr. Hardage, or to join Mr. Hardage in any subsequent action, other than a money judgment, deemed “necessary to allow EPA or its designees to remediate or respond to conditions at the Site or take actions necessary to protect the public health, welfare or the environment.”

On June 25, 1986, the United States filed the instant action, United States v. Hard-age, against 32 generators and three transporters, each of whom allegedly shipped between 100,000 and 1.7 million gallons of hazardous wastes to the site. The United States also sued Mr. Hardage for the limited purposes specified in the Court’s earlier dismissal. As in Hardage I, the complaint in Hardage II sought injunc-tive relief under section 7003 of RCRA and section 106(a) of CERCLA to require the defendants to clean up the site, and to recover costs incurred by the United States under section 107 of CERCLA.

Most of the original defendants in Hard-age II organized themselves as the HSC defendants. The HSC’s answer in Hard-age II asserted numerous affirmative defenses and counterclaims against the United States. The HSC defendants in turn brought a third-party complaint against approximately 180 additional third parties for contribution, and to obtain reimbursement of the HSC’s costs expended in taking response and remedial actions at the Hard-age Site.

C. Bifurcation of Case

In a Case Management Order issued on March 26, 1987, the Court bifurcated the case into two phases, with the Liability Phase to be tried prior to the Remedy Phase. Case Management Order at 7. The allocation of the ultimate cost of any court-ordered cleanup would follow later. Most of the defendants, however, stipulated to liability under sections 106 and 107 of CERCLA. As a result, the Court, in entering judgment as to the HSC defendants’ liability on November 10, 1988, amended its Case Management Order to provide for the Remedy Phase to be tried as Phase I. Judgment and Order (Nov. 10, 1988) (filing No. 1553). The Court’s judgment also delineated the scope of the Phase I trial. The trial was to include “issues of appropriate response-remedial measures” for the Hardage Site, “the entitlement to and amount of response costs, if any, and the extent, if any, of [the United States’] liability” pursuant to the defendants’ counterclaims and affirmative defenses. Id. at 3. The Court indicated that Phase II of the trial would determine whether defendants, other than the HSC, were liable under sections 106 and 107 of CERCLA, 42 U.S.C. §§ 9606 and 9607. The judgment also indicated that any trial of cross-claims or third-party claims for contribution would be separate from the United States’ action and would not commence until Phases I and II were completed.

D. Alternate CERCLA Cleanup Provisions

The CERCLA provides the United States with three alternate methods of providing for the cleanup of hazardous waste sites. Section 104(a) permits the government to use Superfund monies to clean up sites, and then to seek recovery of the response costs from responsible parties under section 107(a). Section 106 provides two other methods for site cleanups when the EPA determines that the site conditions “may [pose] an imminent and substantial endangerment to the public health or welfare or the environment.” 42 U.S.C. § 9606(a) (1982). Section 106(a) permits the EPA either (1) to require the Attorney General “to secure such relief as-may be necessary to abate such danger or threat” by filing a civil action in federal district court seeking an injunction to compel responsible parties to perform such relief, or (2) to issue administrative orders “as may be necessary to protect public health and welfare and the environment.” Id.

The EPA studied and investigated the Hardage Site and incurred response costs in the process. However, the EPA did not clean up the site itself under section 104(a) of CERCLA. Instead, the United States pursued injunctive relief, in Hardage I against Mr. Hardage and in this case against the generators and transporters of hazardous substances, to require the defendants to clean up the Hardage Site. 42 U.S.C. § 9606 (1982 & Supp. V 1987). This distinction is significant, because the scope of the remedy trial conducted in December 1989 was determined directly by the EPA’s pursuit of injunctive relief and by earlier rulings of this Court concerning the scope of review of the EPA’s selection of response actions.

E. Scope of Review of the EPA’s Remedy Selection

Throughout this proceeding, the United States has advocated that the scope of judicial review of the EPA’s remedy selection for the Hardage Site should be restricted to review of the administrative record on an arbitrary and capricious standard. However, on three separate occasions, the Court ruled that the scope of review would be de novo review of any remedy suggested by the EPA.

The record review issue first arose in the context of the United States’ November 17, 1986, motion for protective order, which sought to limit the scope of deposition discovery by defendants of two contractors employed by the EPA to aid in developing a remedy. Judge West, on December 11, 1986, denied the motion for protective order. United States v. Hardage, 25 Env’t Rep.Cas. (BNA) 1343, 1986 WL 647 (W.D. Okla.1986). The Court emphasized that the administrative record had not yet been filed. Id. at 1344. The Court found that the SARA record review provisions were not applicable to the United States’ claim for injunctive relief under section 7003 of RCRA. Id. at 1344-45. In addition, the Court held that restrictions on judicial review did not apply to injunctive actions generally. Id. at 1345. The Court also concluded that the provisions of the Administrative Procedure Act were inapplicable. Id. Judge West ruled that section 106 injunctive claims “must be resolved in traditional trials by federal district courts after full discovery.” Id. The Court further concluded that the “defendants are entitled to de novo review of any suggested remedy by EPA at the Hardage site.” Id.

On April 9, 1987, the Court denied the United States’ motion for reconsideration. United States v. Hardage, 663 F.Supp. 1280, 26 Env’t Rep.Cas. (BNA) 1053 (W.D. Okla.1987). The Court ruled, in addition to its prior-stated rationale, that SARA record review provisions could not be applied retroactively to actions filed before the passage of SARA, and that a restricted judicial review of the EPA’s remedial decision raised due process concerns. Id. 663 F.Supp. 1280, 26 Env’t Rep.Cas. (BNA) at 1055, 1059-61. The Court also distinguished injunctive actions brought in federal district court pursuant to section 106 of CERCLA from those brought administratively under section 106 for injunctive relief, and from actions for cost recovery under section 107 in instances in which the EPA funds site cleanups. Id. 663 F.Supp. 1280, 26 Env’t Rep.Cas. (BNA) at 1056.

Once it was compiled, the United States certified to this Court on March 15, 1988, the administrative record supporting the EPA’s November 14, 1986, ROD. The United States then moved for the Court to restrict judicial review of the EPA’s remedial decision to the administrative record. On March 15, 1988, the United States also moved to dismiss its count based on section 7003 of RCRA.

On July 14, 1988, this Court granted dismissal of the RCRA count. However, in a minute order dated September 9, 1988, the Court denied the United States’ motion for record review, citing the Court’s prior decisions on the motion for a protective order, dated December 11, 1986, and April 9, 1987. The Court also found as a matter of law that section 106 claims “must be resolved in traditional trials by federal district courts after full discovery, and that retroactive application of Section 113(j) of SARA is improper.” Minute Order (Sept. 9, 1988) (filing No. 1435). On September 9, 1988, the Court issued an accompanying memorandum decision stating that reversal of the Court’s earlier rulings concerning the scope of review was not warranted by the United States’ withdrawal of the claim based on section 7003 of RCRA or by the United States’ filing of the administrative record in March of 1988. Order on Motion to Restrict Review (Sept. 9, 1988) (filing No. 1434).

Accordingly, the Remedy Phase proceeded to trial with this Court conducting a de novo review of the United States’ proposed remedy for the Hardage Site. However, under any standard of review, the Court’s decision on the remedy would have been the same.

F. Special Master

Early in this litigation, the Court recognized that the complexity of the issues, the number of parties, and the need to expedite matters to ensure protection of the public welfare might require the appointment of a special master under the provisions of Rule 53 of the Federal Rules of Civil Procedure. Toward that end, at a status conference on September 3, 1986, the Court directed the parties to submit a list of the names of 10 persons they believed would be qualified to serve as a special master. On October 1, 1986, the parties filed their lists of suggested candidates for special master. In addition, the United States supplemented its submission with the policy of the Attorney General of the United States on the use of special masters. The United States opposed the use of a special master as a technical advisor to the Court, but agreed a master might help resolve discovery disputes and could assist with the settlement process.

After interviewing candidates for the position of special master, on February 25, 1987, the Court issued an order citing the following reasons for appointing a special master:

(1) The case would require urgent resolution due to a threat to the public welfare.

(2) Analysis of technical and scientific data would be required to determine complex issues of liability and apportionment.

(3) Issues would be complicated by the number of parties and the commingling of the waste.

(4) The vast amount of evidence necessary to litigate this case would result in extensive discovery which would require almost constant supervision.

In the order, the Court appointed Alexander H. Danzberger as a special master for the Hardage case. The order delineated the master’s duties and authority. Order of Reference to Special Master at 12-13. In addition, the Court established a Master’s Reimbursement Fund of $70,000 to meet the expenses of the master during his term of service to the Court.

During his three years as special master, Mr. Danzberger:

(1) Conducted formal hearings on the record at the Court’s direction concerning the proposed Case Management Order and assisted in a hearing on a temporary restraining order on drilling at the site.

(2) Served as hearing officer on pretrial matters.

(3) Provided negotiation assistance to facilitate agreement on the Consent Decree for HSC’s performance of the Second Operable Unit Remedial Investigation/Feasibility Study — Management of Migration.

(4) Recommended settlement strategies in magistrate’s hearings.

(5) Facilitated discussion between the parties on site characterization issues, on interpretation of scientific data, and on the extensiveness of remedy requirements.

(6) Provided periodic reports to the Court regarding litigation progress.

The Court publicly expresses its appreciation of Mr. Danzberger’s service as special master. His efforts have facilitated open discussion between the parties, have aided in narrowing technical issues, and have streamlined the efficiency of this litigation. Because of the scope of review of the Remedy Phase, Mr. Danzberger played no role in that trial or in the preparation of this Order.

VII. FLAWS IN THE GOVERNMENT’S PROPOSED REMEDY

A. Overview

1. The primary basis for the Court’s rejection of the government’s proposed remedy and its selection of the HSC remedy is fairly straightforward. The heart and soul of the government’s proposed remedy is excavation. While the Court was impressed with a number of the government’s soil vapor extraction witnesses, the Court was not persuaded at all by the few witnesses called by the government and the Consent Decree parties who testified in support of the appropriateness, feasibility, and safety of excavation. Other reasons for the Court’s remedy preference include the State of Oklahoma’s opposition to the government’s excavation proposal, the lack of due consideration given to the views of state authorities, the ambiguity of the excavation proposals presented in the government’s case, the unreliability of the government’s estimates concerning the number of intact drums in the main pit and barrel mound areas, the vacillating nature of the government’s proposed remedy, and the observations found in government documents concerning excavation and containment remedies at the Hardage Site. There are also other flaws in the government’s remedy that are discussed more fully below.

2. The Court believes the public health, safety, and welfare and the environment are best served by the modified HSC remedy that will be ordered by the Court. The Court thus finds that the government has failed to establish the excavation aspect of its proposed remedy by a preponderance of the evidence. The Court also finds that excavation is similarly inappropriate for purposes of the Consent Decree.

3. While the Court considered studying the possibility of utilizing soil vapor extraction in connection with the HSC remedy, a review of all of counsels’ closing arguments and final comments to the Court, as well as certain evidentiary factors identified by Dr. Richard Brown on December 7, 1989, and testimony by other witnesses cited below, persuaded the Court that it should not attempt a hybrid remedy or include soil vapor extraction as part of the remedy ordered for the Hardage Site. Accordingly, there will be no soil vapor extraction component in the remedy ordered by the Court.

B. Vacillating Nature of the Government’s Remedy

1. The government’s proposed remedy changed so many times during the course of this litigation, and in such drastic measures, that the Court lost confidence in the deliberative process underlying the government’s final proposal. The government’s final proposed remedy came so late in the litigation that the Court has difficulty believing that it was carefully considered.

2. Despite years of preparation, partial excavation combined with soil vapor extraction was not announced as a part of the EPA’s trial remedy until October 1989. GE 2 sec. 3.2.4, at 3-36.

3. The EPA’s ROD that contained the government’s selected remedy was not filed until November 22, 1989. This was the Wednesday before the Thanksgiving holiday. The trial of this case began on November 24,1989, at 7:30 a.m., the Friday after the Thanksgiving holiday. Allyn Davis, the EPA’s director of hazardous waste management for Region VI, signed the EPA’s ROD two hours after giving his deposition on November 24. It was not provided to defense counsel until the eve of the trial. The ROD contains boxes and boxes of materials. V at 1160-63.

4. The vacillating nature of the government’s proposed excavation remedy is demonstrated by comparing the deposition testimony of the EPA hazardous waste director, Mr. Davis, on November 22, 1989, with his trial testimony on November 30, 1989. V at 1162-67; VI at 1191-96. Also, the earlier EPA proposals involved excavating more than the barrel mound and main pit. V at 1125, 1130, 1134. The earlier EPA proposals advanced a “pin cushion” theory, under which the source areas would be lanced and drained. This proposal was abandoned prior to trial. IV at 873-74; V at 1135-36. Unfortunately, it is extremely difficult for the Court to evaluate a proposed excavation plan until the government has decided on an excavation proposal. V at 1117. Various government witnesses advanced more than three excavation proposals. V at 1103-04.

5. The government’s risk assessment was based on an approach, suggested in the government’s remedy design report, involving the extraction of liquids through wells prior to excavation; but that method was not advanced as part of the government’s trial remedy. GE 2 sec. 3.2.4, at 3-36; III at 450.

6. On the morning of December 1, 1989, upon questioning by the Court, defense counsel pointed out the different inconsistencies between Mr. Davis’ testimony, the EPA’s ROD, and the government’s proposed remedy. Government counsel acknowledged that there was an “error in the draftsmanship” of the ROD in that the ROD suggested vertical extraction wells in all three source areas, as well as pooled liquids in all three source areas, concepts clearly inconsistent with the government’s trial remedy. VI at 1191-96; V at 1162-67.

7.The government’s changing remedies also adversely affected its evidentiary presentation at trial. One conceptual difficulty with a government expert’s soil vapor excavation feasibility model was that the model was prepared when the EPA’s lancing remedy was under consideration. This soil vapor extraction model, which was based upon a lancing theory, was not changed after the EPA’s excavation remedy displaced the lancing remedy. IV at 873-74; XII at 2359-60. See IV at 801.

C. The Excavation Component of the Government’s Remedy

1. In addition to the remedy components suggested by the HSC, the remedy for the Hardage Site proposed by the EPA includes partial excavation of materials from the barrel mound and main pit, and soil vapor excavation in the barrel mound, main pit, and sludge mound. GE 2 at 2-1 to -4.

2. Excavation to remove buried hazardous wastes has been successfully implemented as a remedial measure at various hazardous waste sites around the country.

3. Excavation of buried hazardous wastes, including drums, is a recognized method of remediating hazardous waste sites. R. Davis R.Aff. at 3; V at 1098.

4. It is estimated that approximately 18,000 drums are buried in the barrel mound and the main pit. Supplemental Joint Statement of Uncontested Facts para. 81.

5. At the outset of the trial, the Court was logically and conceptually attracted to the government’s excavation remedy. Although countered by defense experts, three impressive government witnesses (Dr. Kirk W. Brown, Thomas Prickett, and John Robertson) testified that the contamination was spreading at the Hardage Site and that excavation would remove the bulk of the waste from the source areas before the contamination could spread further. None of these three witnesses, however, were presented to the Court as excavation experts. Indeed, had the government followed up these conceptual presentations with credible evidence concerning the feasibility, safety, and appropriateness of excavation at the Hardage Site, a different result might have occurred. It was in the practical aspects of excavation at the Hard-age Site that the government’s case fell apart.

6. The government called two witnesses to testify to the practical aspects of excavating the Hardage Site, Robert Davis and John Brack. Also, a Consent Decree party, United States Pollution Control, Inc. (“USPCI”), called Steve Beck to testify on the same point. By agreement of all parties, Mr. Beck’s testimony was to be considered by the Court for trial purposes as well as for the Consent Decree. The testimony of these witnesses totally failed to convince the Court that excavation was an appropriate remedy for the Hardage Site. In fact, this testimony convinced the Court of precisely the opposite — that the government’s proposed excavation plan was totally inappropriate for the Hardage Site.

7. The three government witnesses who testified about the planned excavation at the Hardage Site each described a different approach. V at 1103-04; IV at 745-50; III at 541-46.

8. The failure of the government to present a detailed, consistent proposal for drum excavation, an ultrahazardous activity, raises serious questions about the ability of the EPA to implement excavation safely at the Hardage Site. V at 1117.

9. Photographs of site operations indicate that intact drums were disposed of in the barrel mound and in the main pit in a haphazard fashion. DE 30 tab D. A recent test excavation in the main pit indicates that some intact drums remain buried. DE 168.

10. The barrel mound and the west side of the main pit were constructed haphazardly, resulting in drums lying in disarray within voids and channels within and around them. Schmittle Decl. at D-21 to -22; DE 30 tab D.

11. Excavation is not an appropriate remedy for the Hardage Site because of the way the drums were deposited and dumped. DE 30 tab D. At other hazardous waste sites, drums or barrels are placed in specific locations in a specific array. The placement of drums at the Hardage Site, however, was random. Id. IV at 752-829. The OSDH opposes the EPA remedy primarily because of the proposed excavation. Coleman Decl. at B-5; III at 588-620.

12. The OSDH is the agency of the State of Oklahoma, which is responsible for regulating the management and disposal of its hazardous waste, that should ensure the protection of the public health and welfare and the environment. The OSDH is the designated Superfund agency within the state. See Okla.Stat. tit. 63, §§ 1-2001 to -2021 (1981 & Supp.1987).

13. Before its trial remedy report was issued, the EPA had no discussions directed toward obtaining the OSDH’s views on the proposed excavation remedy. Ill at 610-11.

14. The EPA had not sought the OSDH’s views prior to selecting the excavation and vault remedy announced in the EPA’s 1986 ROD. Coleman Decl. at B-3.

15. The OSDH vigorously opposed excavation of the barrel mound and main pit, believing that harmful vapors could be released from the site and that fires or explosions could occur. Coleman Decl. at B-5; III at 588, 590, 620.

16. Excavation is not an appropriate remedy because of the inaccurate nature of the government’s estimates of the number of drums in the main pit and the barrel mound, and the speculative nature of the assumptions regarding the number of drums deposited at the Hardage Site that have ruptured and leaked. IV at 752-833; III at 565-66; VI at 1246-49; V at 1162-70.

17. Excavation experience at other sites suggests that only a small portion, less than 10%, of the drums remain intact and full of liquid. Ill at 560-62. The government’s assumption that more than 12,000 of the estimated 18,000 barrels at the site are full to the brim is fatally flawed. IV at 755-56, 739-833; III at 565-66.

18. Given the manner in which drums were thrown into the Hardage Site, many drums cannot be removed mechanically and placed into overpack drums without workers physically handling the drums. Ill at 522-53, 583; V at 1124-25. This poses serious risks to the handlers.

19. Although many buried drums can be detected as excavation proceeds using subsurface instrumentation, this instrumentation does not describe the nature of a buried drum, the extent to which it has collapsed, and the extent to which the workers may be exposed to contaminants as it is recovered.

20. Certain estimates provided during the testimony of government witness Robert Davis on November 29, 1989, suggesting that there are 660,000 gallons of drummed liquids, are substantially inflated. The evidence, to the contrary, suggests that most of the liquids are in the “known pooled liquids” category. IV at 739-833.

. 21. A critical issue in this case is the number of buried drums at the Hardage Site that remain intact and that have not leaked or ruptured. Given the fact that the evidence strongly suggests that most such drums have ruptured or leaked in some fashion, the marginal utility of excavation as a remedy declines. The evidence suggests that most of the leaked materials can be recovered through the pumping of known pooled liquids. Both the government and the HSC remedies call for such pumping. The legitimate safety concerns with respect to excavation at the Hardage Site, coupled with the marginal utility of excavation given the evidence regarding the number of ruptured drums, persuades the Court that excavation is not appropriate.

22. Contrary to what the EPA representatives told two citizen witnesses, excavation and soil vapor extraction will not remove 90% to 99% of the hazardous waste within 10 to 20 years. IV at 708-32. Groundwater and soil contamination problems will remain at the site forever. DE 175 at 3. Moreover, the Hardage Site can never be returned to its prewaste disposal condition under any remedy. V at 1174. The EPA simply supplied these citizens with copies of its experts’ affidavits and persuaded them that the EPA remedy was the best remedy for the citizens living near the Hardage Site. Critical information was not supplied to these citizen witnesses. As a result the Court has placed little, if any, weight on this testimony offered in support of the government’s excavation remedy.

23. It is likely that very few of the drums remaining at the Hardage Site contain liquids. Schmittle Deck at D-21 to -22; DE 44 at 1, 7, table 1; DE 21 at 3-26, 4-1 to 4-2; DE 30 tab D. In another excavation effort, less than 500 drums were found intact in a 15,000 drum removal effort at a hazardous waste site. Ill at 560-62.

24. The review team leader for the EPA contractor responsible for preparing the 1986 Feasibility Study questioned the propriety of spending millions of dollars to remove the “source” of waste at the Hard-age Site, when the groundwater and soil contamination problems could never be eliminated. DE 175 at 3.

25. This review team leader of the EPA’s draft feasibility study, Steven Hahn, a geotechnical engineer who worked on hazardous waste sites, felt that a “fatal flaw” in the feasibility study was that it did “not carry at least one containment alternative through detailed evaluation.” DE 175 at 3. Mr. Hahn believed a viable containment alternative existed. He further noted that all of the excavation alternatives were “terribly expensive” and questioned the justification “for spending so much money on source removal, considering that extensive groundwater/soil contamination problems will remain at the site forever.” Id. at 1, 3. This document was offered into evidence by the HSC, and was received without objection. IV at 818-34.

26. Mr. Hahn also pointed out the following with respect to the 18,000 drums “assumed” to be at the Hardage Site:

I strongly suspect that most of these are empty now, or will be punctured and/or crushed in the process of excavating the landfill. That was our experience at Berlin and Farro.

DE 175 at 4.

27. Mr. Hannesschlager, a senior EPA enforcement official, in 1985 made a statement to the effect that the Hardage Site was not an imminent threat to the public. DE 174 at 3. In Mr. Davis’ opinion, he was qualified to render such a view. Mr. Davis is the hazardous waste director for the EPA’s Region VI. V at 1174-79.

28. Materials including DNAPL already have escaped from barrels outside the areas to be excavated, thus further reducing the viability of excavation. GE 19; IV at 830; V at 1163-64.

29. The Lyons Landfill site, upon which the government relied as an example of a successful drum excavation, involved fundamentally different conditions than those at the Hardage Site. Hecox R. Decl. at 3-4; III at 685-87.

30. The government’s excavation expert, Mr. Bruck, acknowledged that the government had not yet completed detailed plans for excavation. Excavation, according to Mr. Bruck would fall into one of three approaches. He could not tell the Court which approach should be used. V at 1094-1140.

31. Soil removed from the excavation site would have to be moved, perhaps more than once. R. Davis Rebuttal Aff. at 3-4; V at 1104-05.

32. Construction of the EPA remedy would require workers to spend significantly more person-hours in Level A and Level B protective equipment. Because this equipment severely restricts a worker’s mobility and leads to the buildup of heat within the equipment, implementation of the EPA remedy would increase the risk to workers of heat stress and heat stroke, particularly in the hot summer months. Harris Deck at C-18 to -23; III at 641-43; DE 141; V at 1112-14.

33. Excavating and handling buried drums containing unknown and potentially ignitable, flammable, or reactive chemicals is an ultrahazardous activity. Harris Supp. R.Decl. at 2-3.

34. The testing of intact drums containing unknown substances is an ultrahazardous activity that threatens workers with risks of fire, explosion, and chemical reactions as drums are opened to sample their contents. Harris Supp.R.Decl. at 3.

35. Workers cannot be completely protected from the risk of injury or death if an explosion occurs during excavation. V at 1138; VI at 1236.

36. Although government witnesses assured the Court that measures would be taken to avoid subjecting workers to heat stress during the excavation, including training and scheduling work during cooler periods of the day or of the year, one excavation proposal envisioned workers in protective gear working in summer afternoons. GE 2 at 3-38; III at 523; Bruck Aff. at 4; V at 1105, 1107.

37. The government’s excavation witness, Mr. Bruck, acknowledged that he had little on-site experience. His work as a program manager involved minimal on-site experience. He testified that two excavation shifts could be utilized, one in the early morning and one in the afternoon. The workers would wear level B protection. Level B protection is high-level protection, involving suits, gloves, boots, respirators, etc. Level B protection poses heat stress problems for workers that can be alleviated by multiple work shifts. The notion, however, that workers could perform such work in Oklahoma in summer afternoon temperatures is at odds with the reality of the state’s summer weather. Excavation difficulties would be compounded because Mr. Bruck expected to uncover the type of drum arrays depicted in Defense Exhibit No. 30, tab D. V at 1105-40.

38. During the summer and winter months it may not be practicable, or even possible, to work in Level B protection on many days or for extended periods of time. Harris Deck at C-23; V at 1104, 1112.

39. In order to remove the drums during excavation, workers would necessarily have to handle drums physically and would work in close proximity to waste liquids and excavated drums. II at 206-07; V at 1129-30; DE 30 tab D; DE 44.

40. Because of the way the barrels were left at the Hardage Site (DE 30 tab D), the excavation would require some hand digging. The EPA proposes to use mechanized excavation to the maximum extent possible. V at 1093-1140.

41. Level A protection involves a fully contained, rubberized suit with a pressurized breathing apparatus. Level A gear provides more protection for the worker. The EPA’s proposed remedy would require that more than 50% of the excavation work be performed in Level A gear. The government’s excavation witness, Mr. Bruck, was not aware that the remedy report of the EPA and the Consent Decree require 50% of the excavation work to be performed in Level A gear. V at 1122.

42. The government’s excavation plans are more properly characterized as being at a general philosophical stage rather than at a specific stage. V at 1136; III at 567. The workers performing the excavation, however, realistically would be exposed to a serious risk. Y at 1106-41. This Court is not prepared to risk the safety and lives of Oklahoma workers on such tenuous plans and proposals.

43. The government’s remedy design document does not adequately describe the manner or method of excavation, or the actual procedures contemplated to address the risks of excavation. GE 2 sec. 3.2.4., at 3-36; V at 1106-41.

44. The drum excavation proposed by the EPA envisioned that the drums would be removed intact in order to avoid the release of liquids to the subsurface. II at 264. This plan is not supported by the likely condition of the remaining drums.

45. Drums encountered in the barrel mound would be in a deteriorated condition. Excavation could further crush or puncture the drums, causing substances in them to leak and react with potentially incompatible chemicals present at the site. Schmittle Deck at D-21 to -22; DE 30 tab D; DE 44; DE 179; Hecox III at 690; III at 588-89.

46. There were substantial discrepancies among the government witnesses regarding the amount of exposed surface area for the excavation working face, the plan of excavation, the disposition of soil, and the number of times soil would be moved, all of which adversely affected the Court’s ability to estimate the risks associated with excavation. GE 2 at 3-36 to -39; III at 544, 545, 442-46, 644-68; IV at 778-83.

47. Emission control measures would have to be implemented to prevent dust and vapor emissions during the excavation. These measures would include vapor suppressant foams, and might also include wetting agents, plastic sheeting, visqueen, clean soil, and other materials. R. Davis R.Aff. at 3-4; Bruck Aff. 7; GE 2 at 3-38; III at 543; V at 1101. The government’s nebulous plans regarding this critical and dangerous aspect of excavation do not justify inclusion of excavation as a remedy component for the Hardage Site.

48. Because wind gusts are likely during any excavation of the Hardage Site, the proposed use of a plastic covering to control vapor emissions from stored materials is unlikely to succeed. Bruck Memo (Oct. 5, 1988) (attached to Administrative Record, GE 234).

49. Excavation-based remedies selected by the EPA at various other sites, including the Petro Processors and Rocky Mountain Arsenal sites, have been delayed or reconsidered because of unacceptable vapor emissions. Harris Deck at C-7 to -8.

50. Excavation poses significant risks due to emissions. The dangerous short-term risk to workers is not outweighed by the alleged long-term benefits associated with excavation. The HSC risk expert, Mr. Harris, provided persuasive testimony to the Court regarding the dangers of excavation. Ill at 636-66. The Court found this testimony more persuasive than the testimony provided by the government’s risk assessment expert. II at 409.

51. The EPA remedy includes certain remedy components — excavation of the barrel mound, removal of liquids by vacuum truck, transportation of excavated wastes to a staging area, and construction, operation, and maintenance of the soil vapor excavation system — that create significant implementation risks in addition to the risks created by the remedy components common to the EPA and HSC remedies. Harris Deck at C-10 to -23; DE 140; III at 640, 643-44, 690-91.

52. Implementation of the government’s excavation plan will result in significant risks to local residents. Off-site cancer risks associated with the EPA remedy are understated; estimates of the off-site cancer risks associated with the HSC remedy are likely overstated.

53. Excavation will present a risk of fire, explosion, and physical injury from direct contact with hazardous wastes if incompatible wastes mix during the work. Harris Deck at C-10 to -15; DE 140; III at 640, 643-44, 690-91; VI at 1231, 1233.23.

54. Excavation of the barrel mound/main pit to remove drums and drummed wastes will cause off-site releases of exceedingly toxic substances, such as asbestos, that can contaminate soil and surface water near the site. Those substances can persist long after the remedy is constructed. Harris Deck at C-26, D-4.

55. The EPA failed to evaluate adequately the costs and risks associated with the handling, testing, storage, transportation, and incineration of drums, liquids, sludge, and other materials. Harris Supp. R.Decl. at 3.

56. The EPA’s remedy would place workers in closer proximity to hazardous wastes than the HSC remedy. The EPA remedy thus carries with it a greater risk of workers coming into direct physical contact with hazardous wastes and of being involved in construction-related accidents. Harris Deck at C-18 to -23; DE 141; III at 641-43; V at 1112-14.

57. Excavation of the barrel mound and main pit and soil vapor excavation in the source areas would result in more contaminants being released through vapor and dust emissions than will be released during construction of the HSC remedy. Harris Deck at C-10 to -23; DE 140; III at 640, 643-44, 690-91.

58. Even after excavation, pumping, and soil vapor extraction 500,000 gallons of waste would remain at the Hardage Site under the EPA remedy. IV at 860.

59. Dr. Eugene Meyer assumed, as did other witnesses for the government, that all of the barrels of chemicals deposited at the Hardage Site were full to the brim based on the fact that Mr. Hardage charged his customers on a per barrel basis. The Court cannot accept this assumption. There is no way of determining from the logs the accuracy of the information as to what was delivered to the site, as the Hardage log simply reflects what the Hard-age employees were told when a load arrived. VI at 1245-49. Moreover, the assumption that these barrels remain intact and full today is without factual support.

60. Although drum removal and soil vapor extraction would reduce the volume of waste available for groundwater contamination, the site would not be cleaner as a result of soil vapor extraction and excavation in any time frame that can be envisioned. The site will always be contaminated. XI at 2092-2135.

61. The Court is not convinced by the testimony of the government witnesses that excavation of the barrel mound and portions of the main pit to remove buried drums and free-phase liquids can be implemented safely, minimizing or eliminating risks of injury to workers. Although Dr. Meyer is an exceptionally qualified and impressive witness in many areas, he has little expertise in any aspect of excavation, much less its practical aspects, and the Court has placed little weight on the government’s effort to have him testify in this area.

62. Excavation of the barrel mound and certain portions of the main pit to remove buried drums and free-phase liquids is not a feasible remedial action for the Hardage Site. The government witnesses’ primary point is that a workers’ health and safety plan can be devised for the EPA’s proposed remedy. Ill at 521-22; V at 1099. The Court, however, cannot order an excavation undertaking such as that proposed by the government (in any form) to proceed on the state of this record. The Remedy Phase was designated as the phase of this litigation in which the Court was to order a remedy for the site based on the evidentia-ry presentations of the parties. This Court has no intention of deferring a remedy decision to future excavation studies or plans that perhaps could be developed on any one of several excavation proposals. Cleanup at this site has been delayed long enough. If excavation is an appropriate remedy for the Hardage Site, the government has had more than ample opportunity to prove it. This was not done during the Remedy Phase.

63. Section 106 of CERCLA, 42 U.S.C. § 9606, expressly provides the standard that a court must follow when awarding injunctive relief. That section states a court has “jurisdiction to grant such relief as the public interest and the equities of the case may require” in order to abate what may be “an imminent and substantial endangerment to the public health or welfare or the environment because of an actual or threatened release of a hazardous substance from a facility_” 42 U.S.C. § 9606(a) (1982).

64. Insofar as the cleanup standards contained in section 121 of CERCLA and in the national contingency plan regulations are binding upon the Court, and insofar as these standards may be considered by the Court, they require rejection of remedies that do not meet the threshold standard of protecting the public health and welfare and the environment. See, e.g., CERCLA § 121(b), (d)(1); 40 C.P.R. § 300.68(a), (g)(3), (i)(l) (1989).

65. Excavation was developed and proposed as a remedy component without adequate consideration of site characteristics, and was based on incomplete information and incorrect assumptions about: (i) feasibility, effectiveness, benefits, and cost; (ii) the risk to workers and to the public from implementation; (iii) technical and practical compatibility with other remedy components; and (iv) the views of the State of Oklahoma. Bost Deck at D-30 to -32.

66. The excavation remedy proposed by the EPA presents unacceptable risks to workers, to nearby residents, and to the environment and relies on unspecified approaches that are not cost-effective and that are otherwise inappropriate for conditions of the Hardage Site.

67. The EPA excavation remedy does not satisfy the threshold requirements of sections 106 and 121 of CERCLA and NCP standards for remedies that must protect the public health and welfare and the environment.

68. The CERCLA provides that states shall have the opportunity to review and comment on proposed remedial actions. It does not provide that states shall have a concurrent role in the selection of remedial actions. 42 U.S.C. § 9621(f)(1)(E) (Supp. V 1987).

69. The EPA has not provided the State of Oklahoma with an adequate opportunity to review and comment on the EPA’s proposed remedy for the Hardage Site. Ill at 586-629; GE 234; V at 1149-89.

70. Failure of the EPA to consult adequately with the OSDH on selection of an appropriate remedy for the Hardage Site is inconsistent with the state consultation requirement contained in section 121(f) of CERCLA. Coleman Deck at B-3 to -4.

71. A remedial action for the Hardage Site that is protective of human health and the environment and that is consistent with cleanup standards established by 42 U.S.C. § 9621 does not include excavation of the barrel mound and portions of the main pit to remove pooled liquids and liquids in drums.

72. Excavation and soil vapor extraction are not appropriate components of a remedy for the Hardage Site. Bost Deck at D-7 to -11; Cherry Deck at D-22; Harris Deck at C-40; IX at 1737.

73. The unique nature of the Hardage Site renders excavation a poor remedy based on the evidence presented.

D. The Soil Vapor Extraction Component of the Government’s Remedy

1. Soil vapor extraction is a remedial technology that has been developed to remove volatile organic compounds from unsaturated soils and transfer them to the airstream; the treatment is both effective and well-demonstrated. Walter Aff. at 4; Danko Aff. at 6; IV at 843.

2. By creating subsurface air flow zones, soil vapor extraction can, under appropriate site conditions, increase the rate at which volatile contaminants will be removed from the source areas. Walter Aff. at 6; Walter R. Aff. at 6-7; Bentley Aff. at 4; IV at 898.

3. Soil vapor extraction can, under appropriate site conditions, reduce or eliminate the production of certain degradation compounds that are highly toxic and mobile in the subsurface environment. Walter Aff. at 3, 10.

4. Having rejected excavation, there is little need for further discussion of the soil vapor extraction component of the government’s remedy. Both a defense expert, Dr. Richard Brown, and government counsel have advised the Court against the idea of attempting to combine this feature of the government’s remedy with the HSC remedy. IX at 1730-49; XII at 2344. Moreover, the rejection of excavation has not made soil vapor extraction more attractive for the Hardage Site.

5. The Court has little doubt that soil vapor extraction can be an effective and important remedial technology for a number of hazardous waste sites. Indeed, the OSDH, while opposing the EPA remedy, supports the concept of soil vapor extraction. The use of soil vapor extraction at the Hardage Site, however, does have several shortcomings and potential pitfalls, including the following:

(a) Even when viewed in its best light, soil vapor extraction would remove less than 165,000 gallons of residual liquids from the Hardage Site, representing less than 10% of the 1.8 million gallons at the site. IV at 853; GE 54(a)-(b); GE 56.
(b) Even if the Court adopted the government’s remedy, some of the most mobile and most carcinogenic of the compounds found at the Hardage Site would be likely to volatilize (change from the liquid phase to the air phase) during excavation, thus undercutting the effectiveness of soil vapor extraction and posing a danger as well. IV at 861-62.
(c) Even after excavation, pumping, and soil vapor extraction, there will be approximately 500,000 gallons of waste left at the Hardage Site under the EPA remedy. IV at 860.
(d) The same results that could be achieved through soil vapor extraction will be obtained through natural diffusion processes. Soil vapor extraction, however, holds out the possibility of achieving these results in five years, as opposed to the thousands of years necessary for the natural process to take place. Unfortunately, no similar soil vapor extraction process has been in operation long enough to confirm such predictions for the Hardage Site.
(e) Sufficient data does not exist at this time to accurately predict the success of soil vapor extraction at the Hard-age Site. IV at 902. Gary R. Walter, an impressive government expert, testified that he knew of no site like the Hardage Site where soil vapor extraction has been successfully implemented. IV at 902. The model for the government’s remedy has not been validated at a similar site. IV at 903.
(f) Soil vapor extraction will not remove a significant number of semi-volatile compounds. IV at 906.
(g) Significantly, the soil vapor extraction proposed by the government would take place only after the government conducted tests to see if it was feasible. Thus, the soil vapor extraction component of the government’s proposed remedy is actually a pilot research program that may ultimately be rejected even if pursued initially. The total cost of the soil vapor extraction system that would be borne by the soil vapor extraction group under the Consent Decree is $12,-168,000. None of the soil vapor extraction witnesses for the government could affirmatively recommend soil vapor extraction as an appropriate remedial action at the Hardage Site. V at 1138; GE 395; II at 305-50, 382-86; IV at 865, 900-08.
(h) Site conditions often determine the effectiveness of soil vapor extraction. Given the problems the Court has found with excavation of the Hardage Site, which one witness has credibly testified would exacerbate any soil vapor extraction effort, the Court is not inclined to order this promising technology for the Hardage Site. IX at 1730-49.
(i) The EPA-proposed remedy requires more operation and maintenance activity than the HSC remedy because of the soil vapor extraction component. DE 16 tables 7.2 & 7.3, at 3; R. Davis R. Aff. table 1, at p. 12 of 12.

6. In short, while the experts on both sides of the soil vapor extraction issue were persuasive, the soil vapor extraction issue cannot be viewed in isolation. The government experts have convinced the Court that soil vapor extraction is an attractive, effective, and promising remedial technology for certain hazardous waste sites. While the Court discounts much of the criticism leveled at this component of the government’s proposed remedy, including that of HSC expert Dr. Hoag, the Court is not convinced, in light of the failure of proof on the government’s excavation component, as well as the other issues outlined above, that soil vapor extraction is appropriate for the Hardage Site.

7. Similarly, under the range of plausible site conditions, based on industry experience at other hazardous waste sites, the Court is not convinced by a preponderance of the evidence that soil vapor extraction technology is a feasible and effective technology for the removal of volatile organic compounds from the source areas at the Hardage Site.

VIII. REMEDIAL ACTION TO BE TAKEN IN THIS CASE — ADOPTION OF THE PRIMARY FEATURES OF THE HSC REMEDY

1. From a remedy selection standpoint, the Court finds in favor of the HSC’s containment remedy as opposed to the government’s excavation/soil vapor extraction remedy. The Court specifically finds that the defense has proved the appropriateness, safety, and feasibility of this remedy by a preponderance of the evidence. Aside from the conceptional and technical flaws associated with the government’s proposed remedy, which are discussed above, the additional reasoning for this remedy preference is set forth below. The Court will, however, order certain modifications to the HSC’s proposed remedy. As set forth below, the remedy ordered by the Court generally adopts the HSC’s proposal concerning recovery wells in the barrel mound, a V-shaped interceptor trench, a southwest line of interceptor wells, surface water monitoring, a water treatment system for groundwater, and institutional controls. The Court, however, also will order liquid recovery wells to be placed in the main pit in light of (1) the clear evidence presented at trial of barrel deposits in the main pit area, and (2) the failure of the HSC remedy to provide for such wells. A cap that was proposed by the HSC will be utilized at the site.

2. In general, the remedy for the Hard-age Site proposed by the HSC consists of a composite cap over the source areas, liquid recovery wells in the barrel mound (and possibly part of main pit), a V-shaped interceptor trench, interceptor wells in the southwest corner of the site, a water treatment system for groundwater collected from the trench and wells, institutional controls, natural attenuation of the alluvial groundwater, and groundwater and surface water monitoring. DE 16 at 1-4. The Court adopts this remedy with the addition of liquid recovery wells being mandated for the main pit, and any other changes noted below. Except as modified in this Order, the remedy ordered in this case shall be in accordance with the HSC remedy design documentation.

3. The HSC remedy was designed to address in a comprehensive way management of the wastes present at the Hardage Site. DE 16 at 1-1.

4. Few if any hazardous waste sites have been studied as thoroughly and as comprehensively by both the government and defendants as the Hardage Site. V at 987-88; Schmittle Decl. at D-2 to -8, D-20 to -29; Cherry Decl. at D-8.

5. EPA Director of Hazardous Waste for Region VI Allyn Davis believes there are liquids that can be pumped at all three source areas at the Hardage Site. V at 1163-64. In the Court’s view, this testimony corroborates the effectiveness of the HSC’s proposed pumping, as well as the Court’s decision to order pumping from the main pit area.

6. Mr. Davis outlined the four means through which the agency planned to achieve its goal of protecting public health at the site: to restrict public exposure to contaminants through surface water, groundwater, the atmosphere, and direct contact. V at 1186. The HSC remedy meets these goals. IX at 1797-98.

7. Four routes for constituent migration from the Hardage Site can be identified: (1) surface or overland flow during site operations; (2) surface or overland flow currently exiting the southwest corner of the site; (3) groundwater flow through fractures in Strata I, II, and III; and (4) groundwater flow through pore spaces of the rock in Strata I, II, and III. DE 111; VII at 1420.

8. The primary route by which constituents have migrated from the source areas to the alluvium of NCC is overland flow or surface runoff. Schmittle Decl. at D-18 to -20; DE 30 tabs B & C; DE 36.

9. Humans potentially may be exposed to hazardous substances released at or from the Hardage Site through four potential pathways for exposure: groundwater migration, surface water migration, air emissions, and direct contact. DE 15 at 4-la; Bost Decl. at D-3 to -4, D-9; DE 111; DE 177; III at 672; V at 1186; IX at 1797.

10. Despite the migration that has occurred, the Oklahoma water quality standards for the waters of NCC have never been exceeded. II at 202, 226; V at 1010, 1179; VIII at 1602.

11. Neither the HSC nor the EPA proposed a remedy that would remove all contaminants from the Hardage Site. Moreover, neither proposed remedy would make the site suitable for use by animals or humans in the foreseeable future. DE 179; II at 201; IV at 805; V at 1174-75.

12. A remedy for the Hardage Site that controls the surface water pathway, precludes site access and direct contact with waste, controls air emissions from the source areas, precludes the use of affected groundwater, and provides for a contingent response to ensure continued maintenance of the quality of NCC goes a long way toward the protection of public health and welfare and the environment. Bost Decl. at D-3 to -7, D-10 to -11; DE 112; III at 672-76.

13. A remedy consisting of the following components would arguably would be effective to address the remedial objectives identified in Finding No. 12: a cap, surface water monitoring, groundwater monitoring, institutional controls, and contingency plans. Bost Decl. at D-6 to -11; Cherry Decl. at D-23 to -25; XI at 2107.

14. The HSC remedy with the modifications ordered by the Court: achieves the remedial objectives identified in Finding No. 12 necessary to protect the public health and welfare and the environment; affords a further measure of protection to the NCC alluvium and NCC by cutting off migration of constituents from the site; accomplishes a further reduction in the already low potential risks to the public health and welfare and the environment posed by the Hardage Site; and captures and removes contaminated groundwater and non-aqueous phase liquids for treatment. Hecox Decl. at D-2 to -3; DE 26; Cherry Decl. at D-25 to -26; Bost Decl. at D-ll; DE 112; XI at 2108.

15. The HSC remedy as modified eliminates all four potential pathways for exposure to substances at the Hardage Site. IV at 1797; V at 1186-87.

16. The HSC remedy, consisting of the following primary components, other components described in the HSC Preliminary Design Report (DE 16), and certain modifications as indicated below, is protective of the public health and welfare and the environment and should be implemented at the Hardage Site:

(a) V-shaped, gravel-filled interceptor trench constructed at the top of Stratum IV to provide hydraulic control of the source areas by capture and removal of affected groundwater and non-aqueous phase liquids for subsequent treatment. Hecox Decl. at D-4 to -5; DE 60 & 88; II at 221; VIII at 1589; IX at 1788.

(b) Composite cap over source areas to prevent direct contact with wastes, to control surface water flow in source areas, to limit erosion of affected soils, to reduce infiltration of precipitation, and to provide passive gas collection and treatment. He-cox Decl. at D-4; DE 93 & 94; VIII at 1697-99.

(c) Permanent vertical liquid recovery wells in the barrel mound and the main pit to extract pumpable liquids for off-site treatment by incineration and disposal in order to protect the stability of the barrel mound and main pit and to reduce the volume of free liquids. Hecox Decl. at D-4; DE 92; Finding No. 26 infra; IX at 1789-1818. In the event off-site disposal of pumpable liquids is unavailable, the Hard-age defendants shall submit an alternative plan to the United States and to the Court for incineration and disposal of such wastes.

(d) Southwest interceptor wells to prevent migration of affected groundwater into the NCC alluvium (in conjunction with the V-shaped interceptor trench). Hecox Decl. at D-4; DE 60 & 88; II at 223.

(e) Water treatment system to treat groundwater collected from the trench and wells to standards applicable for discharge into NCC. Hecox Decl. at D-4; DE 95; IX at 1796. The water treatment system will be operated in such a way as to avoid commingling of liquids from different remedy components without EPA approval. This limitation on commingling does not preclude the commingling of liquids from the V-shaped interceptor trench, vertical liquid recovery wells in the barrel mound and main pit, and the underdrains beneath the cap as shown on Figure No. 18 of the HSC Preliminary Design Report (DE 16) with each other.

(f) Natural attenuation and, if necessary, control of migration of constituents presently found in the alluvial groundwater to effect cleanup of the alluvial groundwater and to prevent significant expansion of the area of affected groundwater. Hecox Decl. at D-4; VIII at 1595.

(g) Institutional controls to limit public access to affected areas, to prohibit future withdrawal of affected groundwater, and to continue the public water supply to area residents. Hecox Decl. at D-2, D-4; DE 97.

(h) A groundwater and surface water monitoring system to monitor groundwater and surface water for continued effectiveness of the remedy. Hecox Decl. at D-4; DE 97.

17. Strata IV, V, and VI, which -will constitute the “bottom” of either the HSC or the EPA remedy, are characterized by the following four natural features:

(a) Low permeability (Strata IV and V);
(b) No material hydraulically conductive fractures;
(c) Saline water; and
(d) Sluggish flow in Strata VI, which will preclude migration of constituents to any usable water supply for millions of years. XI at 2103, 2129.

18. Constituents, including any DNAPL, which have left or will leave the source areas, generally will migrate laterally through Stratum I, II, and III toward the HSC’s proposed V-shaped interceptor trench and southwest interceptor wells. Here they will be captured, removed, and treated. Larson Decl. at D-8 to -10; DE 58, 60 & 88; II at 221-23; V at 1026; V at 1182; V at 1069; VIII at 1590-94.

19. The area of affected groundwater at the Hardage Site extends to the east from the source areas toward the east farm ponds and to the west and southwest into the NCC alluvium. Schmittle Decl. at D — 16—17; DE 33, 34 & 35.

20. Groundwater flow currently discharging into the east farm ponds will be reversed by the V-shape trench and will instead discharge into the trench. Larson Decl. at D-9 to -10; Hecox Decl. at D-6; DE 60; II at 220.

21. Given the nature of the subsurface geology in the southwest corner of the site, the use of interceptor wells there instead of a trench will present less construction uncertainty and less risk to workers during installation. Hecox Decl. at D-7; VIII at 1706-07.

22. The southwest interceptor well system can be constructed and operated to prevent migration of affected upgradient groundwater into the alluvium of NCC and will be as effective in providing hydraulic control of groundwater flow as would a trench. Hecox Decl. at D-6 to -7; Larson Decl. at D-6 to -10; II at 223-24; VIII at 1706-08; V at 1024.

23. By utilizing a southwest well system instead of the trench proposed by the government, the wells will have overlapping spheres of influence, and will be easier to extend than a trench. VIII at 1706-07. The government concedes that there is no significant difference between the trench system and the well system, or significant advantage of one over the other.

24. Aqueous and non-aqueous phase liquids are present at the base of the barrel mound and have been successfully pumped. This indicates that their removal by pumping is feasible during remediation. Schmit-tle Decl. at D-23.

25. Defense Exhibit No. 26 shows the proposed HSC remedy with vertical liquid extraction wells, trenches, etc. Defense Exhibit No. 108 shows the barrel mound with vertical extraction wells under the HSC remedy. With the exception of the modifications discussed in this order, these exhibits provide an accurate overview of the remedy ordered for the Hardage Site.

26. An HSC witness, Mr. Hecox, testified that there are no vertical extraction wells in the main pit under the HSC proposal “because that is an area where Mr. Hardage apparently did not dispose of any drums.” IX at 1789. In response to the Court’s questioning, Mr. Hecox modified this testimony, stating instead that there were no “significant quantities” of drums in the main pit area. Id. The magnetometer tests, however, show that there are barrels there. GE 2 fig. 3-8; DE 30 tab D. Considering also the cross-examination on this issue by government counsel, the Court finds that Mr. Hecox was impeached on this point. IX at 1801-18. There is in fact a considerable concentration of drums on the west side of the main pit.

27. The vertical liquid extraction wells can be constructed and operated effectively to remove existing pumpable liquids in the barrel mound and the main pit, and to remove any liquids that later drain into these source areas. Hecox Decl. at D-7; IX at 1792, 1821-22..

28. Vertical liquid extraction wells at the spacing proposed by the HSC “can effectively remove pumpable waste liquids and contaminated water” from the barrel mound and main pit. Robertson Aff. at 10-11; IX at 1791-92.

29. Vertical liquid extraction wells, given the conditions at the Hardage Site, are a substantially safer method for removing liquids from the barrel mound and the main pit than excavation. IX at 1791. If drums corrode or collapse, the liquid will be picked up by the vertical extraction wells. IX at 1792. There is to be no termination of the vertical extraction wells absent a court order because of the possibility of continuing corrosion and collapse of drums.

30. The primary function of the cap is to prevent direct access of people and animals to potentially contaminated materials at the site. Differential settlement could occur after the cap is installed, attributable to collapsing or disintegrating drums. There are, however, similar problems with the government’s proposed cap as well. VIII at 1698-1726. Mr. Allen described the defendants’ proposed landfill cap. It has vegetation on the top of it. It is intended to be a permanent cap. It includes a passive vapor control system. VIII at 1697.

31. The Court is unable to see any significant advantages in choosing either the government’s proposed cap over the defendants’ proposed cap, or vice versa. Consistent with the suggestion of the government’s counsel in closing arguments, the Court, having now selected the HSC remedy, will adopt the HSC’s cap proposal rather than the government’s. XII at 2344. However, as noted in Finding No. 63 below, certain modifications will be ordered to the cap.

32. A preload constructed over the barrel mound and over a portion of the main pit will minimize long-term total and differential settlements, thereby minimizing the long-term maintenance costs of the cap. Allen Decl. at D-5; VIII at 1697-98.

33. A multilayer cap system consisting of a vegetative cover, topsoil, a clean select fill and drain layer, a recompacted fine-grain layer, and a gravel gas collection layer can be constructed at the Hardage Site and will limit infiltration, will control surface runoff, will control gas emissions from the source areas, will prevent physical exposure to waste material, will control seepage from the sides of the mounds, and will satisfy applicable regulatory requirements. Allen Deck at D-6 to -7; Hecox Deck at D-8 to -9; VIII at 1697-1700. The modifications set forth below as suggested by the OSDH shall also be incorporated.

34. The remedy proposed by the HSC provides for long-term monitoring and maintenance of the cap. VIII at 1727. If problems with the cap develop, they are to be promptly brought to the attention of the Court.

35. Toe drains installed at the base of the cap along the west, south, and north sides of the source areas will collect any lateral seepage. Hecox Deck at D-9; VIII at 1697.

36. The groundwater treatment system proposed by the HSC will be effective in reducing the volume, toxicity, and mobility of any constituents present in the construction phase storm water runoff and in the groundwater recovered from the V-shaped interceptor trench and southwest interceptor wells. Hecox Deck at D-9 to -10; II at 222; V at 1173.

37. Institutional controls, including the acquisition of interests in adjacent property, an alternative water supply, and site security are necessary at the Hardage Site under either the HSC remedy or the EPA remedy in order to eliminate unauthorized withdrawal and use of affected groundwater from the original Hardage Site and the NCC alluvium. Hecox Deck at D-2, D-10 to -11; V at 1180.

38. The HSC’s proposed monitoring program will produce the data necessary to assess the operation of the following remedial components: hydraulic control of the V-shaped interceptor trench and southwest interceptor wells, liquid levels in the vertical liquid extraction wells, flushing of the NCC alluvium, and movement of constituents in the alluvium. Hecox Deck at D-ll to -12.

39. It is a common practice among scientists and engineers addressing hydrogeo-logic issues to base conclusions about subsurface conditions on information derived from boreholes that sample only a small portion of the whole site area. XI at 2103-04.

40. The subsurface geology of the Hardage Site to a depth of about 300 feet consists of six distinctive bedrock strata (Strata I-VI) with separate hydraulic properties. These major lithologic units are unbroken by faults or major offsets of any kind, are laterally continuous across the site and for several miles, and are flat lying (or nearly so). Schmittle Deck at D-8 to -11, D-13 to -14; Mitchell Deck at D-3 to -4; Keys Deck at D-5 to -7; Papadopu-los Deck at D-4 to -5; DE 27, 28, 29, 30 tab A, 53, 54 & 57; VI at 1343-44.

41. Based on the geophysical logging at the site, it is possible to correlate stratigraphic units under the site and to identify a predominance of mudstone. DE 53, 54-57; VII at 1473-75.

42. Hydrogeologically, the site is characterized by a “fresh water zone in the shallow bedrock (Strata I, II, and III) that flows toward and discharges to the alluvium” of NCC, plus a “saline zone (Stratum VI) that underlies the fresh water zone and is hydraulically separated from it” by the low hydraulic conductivity mudstones and silty mudstones of Strata IV and V. Schmittle Deck at D-13. See DE 27, 28 & 29.

43. The lower part of Stratum IV (below elevation 1,020 mean sea level (m.s.l.)) and Stratum V have extremely low permea-bilities or hydraulic conductivities. Taking into account the results of packer tests, laboratory tests, pressure pulse tests, water level recovery tests, and regional modeling, the horizontal hydraulic conductivities of these strata are indicated to be on the order of 10 ~8 centimeters per second (cm/s) and the effective metrical hydraulic conductivities are in the range of 10 _1° to 10 ~12 cm/s. Papadopulos Deck at D-4 to -16.

44. The extremely low permeabilities result in the vertical flow of water downward through Strata IV and V being very slow, requiring approximately 40,000 years for water to travel one foot into the mudstone. Papadopulos Deck at D-19; DE 67; VII at 1520.

45. The presence of saline water at a depth beneath the site indicates that the material above the saline water is of very low permeability, as it has not permitted a downward recharge of fresh water from the surface. VII at 1475.

46. The geochemical evidence from the chloride leach tests supports the hydraulic evidence that groundwater flow in Strata IV and V is extremely slow. Cherry Deck at D-ll to -13; XI at 2099-2103.

47. In the light of chloride profiles for Stratum IV, lateral groundwater movement below the upper 20 feet of Stratum IV, as depicted in Government Exhibit No. 95, is highly unlikely. XI at 2100.

48. No credible evidence of interconnected, hydraulically conductive fractures in Stratum IV and V of the site has been found. Cherry Deck at D-13 to -18; Keys Deck at D-8 to -9; II at 173-74; VII at 1476-78, 1499, 1504; VII at 1519, 1522; XI at 2100-02.

49. Any fractures that might be present within the lower portion of Stratum IV (below 1,020 feet m.s.l.) and V do not constitute significant pathways for constituent movement; any movement of contaminants that might occur would be to Stratum VI, which is characterized by saline water and extremely sluggish flow, and thus such movement, if it should occur, would not constitute a threat to the public health and welfare or the environment. Cherry Deck at D-13 to -19; XI at 2101-03.

50. The Stratum IV mudstone is very stable geologically and will not shrink or crack when exposed to deionized water, saline water, waste-containing water from the Hardage Site, or DNAPLs. Mitchell Deck at D-3 to -4, D-6 to -7; DE 30 tab F; VI at 1345, 1349-56.

51. Strata IV and V form an effective, regionally extensive, and continuous hydraulic barrier to vertical migration of constituents. Cherry Deck at D-20; VII at 1522.

52. The water beneath Stratum III has no foreseeable value as a water resource for either human consumption or agricultural purposes. Cherry Decl. at D-10; VII at 1473; XI at 2098, 2103, 2130.

53. Stratum VI is a zone of lateral groundwater flow in which the flow rate is negligible, even when considered over thousands of years. Cherry Decl. at D-19; VII at 1521; VIII at 1647-48; XI at 2103, 2129-30.

54. The travel time of any contaminants through the lower portion of Stratum IV and through Stratum V to the saline water in Stratum VI, and eventually to the Wa-shita River, would be on the order of millions of years. VII at 1421; VIII at 1647-48.

55. For the implementation of the HSC remedy, the maximum individual lifetime cancer risk is “considerably less than that considered acceptable under the EPA’s published guidelines.” Harris Decl. at C-24. See Harris Decl. at C — 33; III at 648-50.

56. The cancer risk associated with implementing the HSC remedy is substantially less than that of implementing the new EPA excavation and soil vapor extraction remedy. Harris Decl. at C-24; DE 139; III at 648-50.

57. Implementation of the HSC remedy “will not result in either significant short-term or long-term public health risks to off-site residents.” Harris Decl. at C-24; see id. at C-33.

58. The estimated cost of the HSC remedy, including major capital replacement contingencies, operation, and maintenance, in 1989 dollars, is $53,952,000. DE 16 tables 7.1 & 7.2; DE 98(a), (b).

59. Section 106 of CERCLA, 42 U.S.C. § 9606, expressly provides the standard that a court must follow when awarding injunctive relief. Section 106 provides that a court has “jurisdiction to grant such relief as the public interest and the equities of the ease may require” in order to abate what may be “an imminent and substantial endangerment to the public health or welfare or the environment because of an actual or threatened release of a hazardous substance from a facility_” 42 U.S.C. § 9606(a) (1982).

60. The HSC’s remedy as modified by the Court protects human health and the environment and complies with ARARs, provides long-term effectiveness and permanence, reduces the toxicity, mobility, and volume of the wastes, provides short-term effectiveness, is easily implemented, and is cost effective. Bost Decl. at D-15 to -17; Hecox Decl. at D-13 to -14; Coleman Decl. at B-4; IX at 1797-99.

61. The HSC has kept the OSDH informed about site investigations and the remedy selection process since the HSC first became involved at the site. Coleman Decl. at B-4; III at 612.

62. The OSDH supports a remedy consisting of the components of the HSC remedy, but with a cap having a thicker clay layer than that currently proposed by the HSC, and with a system for removing vapors that gather in the gas collection layer under the cap. Coleman Decl. at B-4-5; IX at 1799.

63. The HSC remedy shall be modified to meet the OSDH’s preferences about the thickness of the clay cap and about an active gas removal system under the cap. IX at 1799.

64. The HSC remedy is fully developed and can be readily implemented to address conditions at the Hardage Site. The HSC’s proposed remedy as reflected in the HSC remedy design documentation contains sufficient detail and specificity so that it may be ordered in a mandatory injunction under section 106 of CERCLA subject to the modifications herein.

65. There are approximately 1.8 million gallons of liquid waste at the Hardage Site. IV at 853, 860. Under the HSC remedy a significant amount of liquid will remain in the source areas, particularly the barrel mound. This is also true, however, of the government’s proposed remedy, which would leave at least 500,000 gallons in the source areas even after the proposed excavation and soil vapor extraction. IV at 860.

66. Insofar as the section 121 cleanup standards are applicable or may be considered by the Court, the HSC’s proposed remedy best satisfies those standards.

(a) The HSC’s proposed remedy complies more fully with the provisions in CERCLA that require that remedies address the “persistence, toxicity, mobility, and propensity to bioaccumulate of ... hazardous substances and their constituents.” CERCLA § 121(b)(1)(C), 42 U.S.C. § 9621(b)(1)(C) (Supp. V 1987). The HSC remedy will not release as much dust and vapor into water, soils, and vegetation surrounding the site, and therefore is less likely to introduce chemicals into the food chain that may bioaccumulate and cause cancer and other adverse health effects.
(b) The EPA’s proposed remedy, in contrast to the HSC’s remedy, presents a significant “short- and long-term potential for adverse health effects from human exposure.” CERCLA § 121(b)(1)(D), 42 U.S.C. § 9621(b)(1)(D) (Supp. V 1987).

67. The HSC defendants have proven by a preponderance of the evidence, and also by the clear weight of the evidence, that the HSC remedy, as modified herein, best:

(a) satisfies the section 106(a) standards for health and welfare and the environment;
(b) satisfies, and is most consistent with, all applicable or relevant section 121 cleanup standards; and
(c) satisfies, and is most consistent with, all applicable or relevant NCP standards.

IX. CONSENT DECREE FOR IMPLEMENTATION OF PARTIAL REMEDIAL ACTION

A. Introduction

On the eve of trial, three days before the scheduled opening statements in the trial of the Remedy Phase, the United States on November 21, 1989, lodged with this Court a Consent Decree for the Implementation of Partial Remedial Action: Source Excavation and Soil Vapor Extraction (“Consent Decree”). By the provisions of the Consent Decree, eight defendants and six federal entities agreed to pay for and perform certain elements of the United States’ desired remedy for the Hardage Site. Based on the Consent Decree, and the fact other defendants allegedly agreed to implement the remainder of the United States’ remedy proposal, the government argued that no Remedy Phase trial should be held. United States’ Pretrial Brief at 2. However, the HSC defendants strongly opposed the proposed settlement and its approval in a brief submitted on November 22, 1989, and demanded that the Court reject the decree out of hand. HSC Brief in Opposition to Proposed Carve-Out Settlement at 3. Alternatively, the HSC requested that the Court defer consideration of the Consent Decree until after the Remedy Phase trial. Id. at 34.

After hearing arguments on November 24, 1989, and considering the procedures for lodging and standards of review for consent decrees, the Court rearranged the trial schedule to take testimony concerning the Consent Decree. I at 62-66. Eight expert witnesses testified on behalf of the United States and the settling defendants concerning the hazardous wastes at the Hardage Site, technical aspects of the remedy elements of the Consent Decree, and their implementation. Four HSC experts disagreed with the appropriateness of excavation and soil vapor extraction for the Hardage Site. In addition, the HSC presented excerpts of the deposition of an EPA official.

At the close of the presentation, the Court found the record on the Consent Decree to be inadequate. Ill at 705. Questions concerning the wisdom of soil vapor extraction and excavation at the Hardage Site remained, together with concerns about the contribution provisions of the decree. Id. In addition, the Court desired to ensure that the remedy “imposed in connection with the Hardage site is in the public interest.” Ill at 706. Accordingly, the Court took the Consent Decree under advisement and directed the rest of the Remedy Phase trial to proceed. Id.

Earlier sections of this Order discuss the Court’s findings of fact and conclusions of law concerning the flaws in the United States’ proposed remedy and the remedial action to be implemented at the Hardage Site. See supra Sections VII & VIII. The Court now considers the Consent Decree.

On January 25, 1990, the United States filed a motion to enter the Consent Decree as an order of this Court. The motion reflected that Mark S. Coleman of the OSDH had filed comments on December 20, 1989, expressing concerns about the risks created by excavation of the Hardage Site. The United States responded to each of Mr. Coleman’s comments in its motion. The HSC defendants responded on February 8, 1990, in opposition to the entry of the Consent Decree. For the reasons set forth below, the United States’ motion for entry of the Consent Decree is DENIED.

B. Legal Discussion

1. Statutory Authority

The CERCLA authorizes agreements concerning response and remedial actions. Under section 122, the President may enter agreements with potentially responsible persons to perform any response action if:

the President determines that such action will be done properly by such person. Whenever practicable and in the public interest, as determined by the President, the President shall act to facilitate agreements under this section that are in the public interest and consistent with the National Contingency Plan in order to expedite effective remedial actions and minimize litigation.

42 U.S.C. § 9622(a) (Supp. V 1987). The CERCLA mandates the filing of such agreements in the appropriate United States District Court as consent decrees at least 30 days prior to entry of a final judgment. 42 U.S.C. §§ 9622(d)(1)(A), (d)(2)(A) (Supp. V 1987). The act requires a comment period for persons not named as parties to the action. 42 U.S.C. § 9622(d)(2)(B) (Supp. V 1987).

In this instance, the United States filed the Consent Decree on November 21, 1989. Therefore, the 30-day comment period expired on December 21, 1989.

2. Standard of Review

When this Court approved the $11 million Consent Decree for De Minimis Settlement and entered it as a judgment of this Court on September 22, 1989, the Court applied the articulated standard of review: whether the settlement is fair, reasonable, and consistent with the purposes of CERCLA. See Transcript of Sept. 22, 1989, Hearing at 59 (Oct. 2, 1989); City of New York v. Exxon Corp., 697 F.Supp. 677, 692 (S.D.N.Y.1988). In reaching this determination, a court considers “the strength of the plaintiff’s case, the good faith efforts of the negotiators, the opinion of counsel, and the possible risks involved in litigation if the settlement is not approved.” Id. (citing United States v. Hooker Chems. & Plastics Corp., 540 F.Supp. 1067, 1075 (W.D.N.Y.1982)). The Court makes these inquiries to “determine whether the decree adequately protects the public interest.” Id. (citing United States v. Conservation Chem. Co., 628 F.Supp. 391, 400 (W.D.Mo.1985)).

In enacting the 1986 amendments of CERCLA, Congress sought to “expedite effective remedial actions and minimize litigation.” 42 U.S.C. § 9622(a) (Supp. V 1987). Settlements achieved through extensive arms-length negotiations, and approved by all counsel and the agency charged with implementation of environmental statutes enjoy a strong presumption of validity. Hooker Chems. & Plastics, 540 F.Supp. at 1080. During settlement proceedings, a court should ensure “that the settlement protects public health and the environment to the greatest extent feasible under currently existing technology.” Id. at 1073.

Where a consent decree involves remedial action, a court assesses reasonableness by considering:

1) the nature and extent of the potential hazards at the site; 2) the availability and likelihood of alternatives to the Consent Decree which would result in cleanup of the surface of the site; 3) the adequacy of the technical proposal of the work which will be undertaken; 4) the extent to which the Consent Decree furthers the goals of the statutes which form the basis for this litigation; 5) the extent to which the Court’s approval of the Consent Decree is in the public interest.

United States v. Seymour Recycling Corp., 554 F.Supp. 1334, 1339 (S.D.Ind.1982).

Finally, a court attempts to strike a balance between policies favoring settlement and the need to safeguard the public interest in environmental cases. In United States v. Carrols Development Corp., 454 F.Supp. 1215 (N.D.N.Y.1978), the court summarized the test:

It is not the Court’s function to determine whether this is the best possible settlement that could have been obtained, but rather the Court’s duty is to determine “whether the settlement achieved is within the reaches of the public interest.”

454 F.Supp. 1215, 1222 (N.D.N.Y.1978) (quoting United States v. Gillette Co., 406 F.Supp. 713, 716 (D.Mass.1975)).

C.Witnesses

Eight primary witnesses appeared on behalf of the United States and the settling defendants in support of the approval of the Consent Decree. The witnesses and the topics of their testimony were: Dr. Kirk W. Brown, source area strength and volumes; Marc A. Jewett, hydrogeological considerations; Joseph P. Danko and Dr. Harold W. Bentley, soil vapor extraction feasibility; Dr. Annette M. Shipp, risk assessment of excavation and soil vapor extraction; and Murdock John Cullinane, Jr., comparative costs of the competing remedy proposals. Two USPCI employees, Mary Ann Heaney and Steven A. Beck, testified concerning the safety of excavation. Portions of other witnesses’ testimony were also offered by the parties on the Consent Decree issue.

Four primary HSC witnesses testified in opposition to the Consent Decree and the technical aspects of the remedy elements. These witnesses and the topics of their testimony were: Mark S. Coleman, the Oklahoma State Department of Health’s evaluation of the competing remedy proposals; Dr. Robert H. Harris, comparative risk assessment; Richard C. Bost, endangerment assessment following implementation of the competing remedies and cost comparison; and Gary R. Hecox, containment hydrogeology, ground water remediation methods, and the United States’ proposed excavation system. At the suggestion of the Court and by agreement of the parties, the HSC presented, by designated deposition, the testimony of Dr. Allyn M. Davis, hazardous waste management director, Region VII, concerning the United States’ remedy, and tasks left to HSC by the Consent Decree.

D. Exhibits

The Court received the following United States exhibits in support of the Consent Decree: United States’ Consent Decree Exhibit Numbers 2, 19, 71, 73, 75, 81, 84, 87, 159, 160, 176, 186, 187, 326, 356, 369, 395, and 397. The Court also received the following HSC exhibits: 6-17, 21, 30D, 32, 47, 84-99, 106, 109-134, 137-145, 165, 167, 168A, and 169.

E. Contentions of the Parties

The United States urges the Court to approve the Consent Decree. The government advocates that the decree is lawful and fully consistent with Congress’ intent to expedite effective remedial actions through settlement, and therefore is in the public interest. The United States argues the contribution provisions of the Consent Decree are appropriate and that the agreement encompassing resolution of liability of the federal agency waste generators is permitted. The United States contends that the Consent Decree meets the three-pronged test of City of New York v. Exxon Corp., 697 F.Supp. 677 (S.D.N.Y.1988).

Because the Consent Decree contemplates performance of remedial actions, the HSC requests a higher level of scrutiny by the Court than is called for under the Exxon test. However, applying even the less-stringent Exxon test, the HSC contends that the Court must reject the decree as neither fair and reasonable nor consistent with CERCLA. The HSC argues that the United States’ self-settlement gives favorable treatment to the federal agencies. The HSC further contends that the settlement would unfairly shift excessive risks and costs to HSC. The HSC urges rejection because the settlement would contain unlawful terms (contribution provisions that would attempt to extinguish the HSC’s claim for already-incurred response costs), and because the record is inadequate for approval.

2. The United States failed to prove that excavation under the Consent Decree protects public health and the environment. Hooker Chems. & Plastics, 540 F.Supp. at 1073.

3. Should the case law be interpreted to impose on the HSC defendants the burden of demonstrating that entry of the Consent Decree is improper, the HSC defendants have met that burden. United States v. Akzo Coatings of America, Inc., 719 F.Supp. 571 (E.D.Mich.1989).

4. The Consent Decree is not reasonable when viewed under the factors in Seymour Recycling.

5. The CERCLA provides the United States with no authority to settle private party response costs. 42 U.S.C. § 9607(a)(4)(B) (Supp. V 1987).

6. Approval of the Consent Decree is not in the public interest. Exxon, 697 F.Supp. at 692.

7. The Court finds the Consent Decree should not be approved and the United States’ Motion for Entry of the Consent Decree should be DENIED.

X. GOVERNMENT RESPONSE COSTS

A. Introduction

On September 11, 1989, the United States filed a motion seeking partial summary judgment against the defendants. The motion sought a determination of the defendants’ liability under section 107(a)(4)(A) of CERCLA, 42 U.S.C. § 9607(a)(4)(A) (Supp. V 1987), for response costs incurred by the United States in conjunction with the Hardage Site. The United States requested $6,292,065.25 in response costs. In addition, the United States requested a declaration of liability for future response costs. In order to allow for final trial preparation, the Court notified the parties on November 15, 1989, of its preliminary ruling on the United States’ motion for partial summary judgment on response costs. On December 8, 1989, this Court granted the United States’ motion for partial summary judgment as to $5,441,201.25 in response costs, but denied on summary judgment the request for DOJ indirect costs in the amount of $850,864. Order Granting Plaintiffs Motion for Partial Summary Judgment on Response Cost Issues (Dec. 8, 1989) (filing No. 2286). In addition, the Court granted the United States’ motion for declaratory judgment for liability for future response costs, except DOJ indirect costs. Id. at 32.

At the trial of this matter the United States requested: additional DOJ direct labor costs for fiscal 1989 of $93,934; other DOJ direct costs for fiscal 1989 of $831,-750; DOJ indirect costs of $1,042,489; EPA indirect costs of $473,756.50; and prejudgment interest in the amount of $737,-723.41.

B.Stipulations

On November 21, 1989, the parties provided the Court with a written stipulation in this matter. The Court adopts as part of its findings and conclusions the following portions of the stipulation relating to the United States’ response costs. The United States’ response cost portion of the stipulation reads:

114. The Government’s DOJ and EPA cost summaries submitted in support of the motion for partial summary judgment on response cost issue identify invoices which are described on their faces as invoices for Hardage site work. The Government has paid these invoices. The summaries also identify additional invoices which are not described on their faces as specific to the Hardage site. The Government also has paid these invoices.
115. The Government has paid various of its employees the amounts shown on the summaries submitted in support of the motion for partial summary judgment on response cost issue for hours which employees charged on their time sheets to the Hardage case.
116. The Defendants do not dispute that the Government has paid various of its employees the amounts shown on the EPA cost summary attached to the declaration of Nellie Boone and the DOJ cost summary attached to the declaration of Patrick A. McGeehin submitted in support of the motion for partial summary judgment on response costs issues.
117. The indirect cost rates computed by EPA for EPA Region VI were $66 per hour in fiscal year 1983, $60 per hour in fiscal year 1984, $54 per hour in fiscal year 1985, $53 per hour in fiscal year 1986, $52 per hour in fiscal year 1987. The provisional rates for fiscal years 1988 and 1989 are: $52 per hour in fiscal year 1988, and $52 per hour in fiscal year 1989.
118. The number of site-specific hours billed to the Hardage site by EPA Region VI personnel in program divisions in the years 1983 through December 31, 1989 were: 1983, 587; 1984, 409; 1985, 1,105.5; 1986, 1,727.5; 1987, 1,817; 1988, 2468; 1989, 700.

Supplemental Joint Statement of Uncontested Facts at 36-37.

C. Witnesses

Six witnesses appeared on behalf of the United States, by affidavit and through testimony, concerning the United States’ response cost issues. The witnesses and their topics included: William Cooke and Joseph Menchaca, EPA indirect costs; Patrick A. McGeehin, DOJ direct and indirect costs and prejudgment interest; Thaddeus L. Juszczak, Jr., EPA Office of Solid Waste and Emergency Response (“OSWER”); Benjamin Burrell, DOJ rent charges; and Manfred van der Walde, the General Services Administration (“GSA”) Rent System through which federal agencies are charged for space costs and related services. Thomas A. Matunas appeared on behalf of the HSC defendants.

D. Exhibits

The following exhibits were received into evidence at the trial relating to the United States’ response cost issues: Government Exhibit Numbers 239-44, 246-49, 251-52, 253-57; HSC Exhibit Numbers 115,146-53.

E. Contentions of the Parties

The United States contends that it is entitled to recover its response costs expended in conjunction with the Hardage Site and this case under section 107(a)(4)(A) of CERCLA, over and above the costs awarded by the Court in its December 8, 1989, Order Granting Plaintiffs Motion for Partial Summary Judgment on Response Cost Issues, except DOJ Indirect Costs. The costs the United States seeks include DOJ direct costs for payroll and other direct costs of litigation support, court reporter fees, and expert witness fees. In addition, the United States argues that it is entitled to recover both EPA and DOJ indirect costs for activities necessary to support response efforts at the Hardage Site, under methodologies that are fair and reasonable. Finally, the United States requests an award of prejudgment interest.

The HSC responds that the United States is not entitled to recover its indirect costs because of flaws in the United States’ cost accounting system and methodology. The HSC’s arguments include: (1) indirect costs are not response costs as defined by CERC-LA; (2) the United States failed to satisfy the requirements of section 104(c)(1) of CERCLA in order to spend more than $2 million from the Superfund; (3) the United States’ proposed remedies were inconsistent with the National Contingency Plan (“NCP”), therefore costs associated therewith are ineligible for reimbursement; and (4) the allocated indirect costs are inconsistent with the NCP and are not in accordance with generally accepted accounting principles. The HSC contends the inconsistent costs include: on-going costs of government, rent charges, indirect costs incurred when no field work was performed, lack of full capacity, and costs limited by inter-agency agreements. In addition, the HSC argues that the United States’ expenditures are unreasonable, unjustified, excessive, unnecessary, and thus not recoverable under CERCLA, and also that they are unconstitutional. Finally, the HSC contends the United States is improperly seeking an award of prejudgment interest.

F. Legal Discussion — United States’ Response Costs

1. Authority for Awarding Response Costs ■

Section 107(a) of CERCLA imposes liability on four categories of persons — including owners and operators of vessels or facilities, owners and operators of disposal sites, generators, and transporters — for costs including:

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....

CERCLA § 107(a)(4)(A); 42 U.S.C. § 9607(a)(4)(A) (Supp. V 1987). This section authorizes “the government to recover all costs of its removal or remedial [response] actions.” United States v. R.W. Meyer, Inc., 889 F.2d 1497, 1504 (6th Cir.1989) (emphasis in original) (footnote omitted).

Crucial terms within this cost provision have been broadly defined elsewhere in CERCLA. The terms “remove” or “removal” are defined as follows:

The terms “remove” or “removal” means [sic] the cleanup or removal of released hazardous substances from the environment, such actions as may be necessary [sic] 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 damages 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 ... action taken under section 9604(b) of this title....

42 U.S.C. § 9601(23) (Supp. V 1987) (footnote omitted). The section 9604(b)-autho-rized action, referenced in the above-listed definition of “remove,” includes:

such planning, legal, fiscal, economic, engineering, architectural, and other studies or investigations as [the President] may deem necessary or appropriate to plan and direct response actions, to recover the costs thereof, and to enforce the provisions of this chapter.

42 U.S.C. § 9604(b)(1) (Supp. V 1987).

The CERCLA goes on to define “remedy” or “remedial action”, in pertinent part, as follows:

The terms “remedy” or “remedial action” means [sic] 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 a hazardous substance into the environment. ... The term includes, but is not limited to, such actions at the location of the release ... any monitoring reasonably required to assure that such actions protect the public health and welfare and the environment.

42 U.S.C. § 9601(24) (Supp. V 1987) (footnote omitted).

Finally, as currently defined by CERC-LA, “respond” or “response” means “remove, removal, remedy, and remedial action, all such terms (including the terms ‘removal’ and ‘remedial action’) include enforcement activities related thereto.” 42 U.S.C. § 9601(25).

In United States v. Northeastern Pharmaceutical & Chem. Co., 579 F.Supp. 823 (W.D.Mo.1984), aff'd in part and rev’d in part on other grounds, 810 F.2d 726 (8th Cir.1986), cert. denied, 484 U.S. 848, 108 S.Ct. 146, 98 L.Ed.2d 102 (1987), the district court interpreted the government’s response costs to include:

(a) Investigations, monitoring and testing to identify the extent of danger to the public health or welfare or the environment.
(b) Investigations, monitoring and testing to identify the extent of the release or threatened release of hazardous substances.
(c) Planning and implementation of a response action.
(d) Recovery of the costs associated with the above actions, and to enforce the provisions of CERCLA, including the costs incurred for the staffs of the EPA and the Department of Justice.

Id. at 850.

Federal courts have held that the United States is entitled to recover its investigative costs from parties liable under section 107(a). See New York v. General Elec. Co., 592 F.Supp. 291, 298 (N.D.N.Y.1984) (“initial response costs ... are clearly authorized as costs of response under section 101(23), 42 U.S.C. § 9601(23).”); United States v. Wade, 577 F.Supp. 1326, 1333 n. 4 (E.D.Pa.1983) (cost of “investigating, monitoring, testing, and evaluating the situation at the Wade site ... is recoverable as a cost of removal.”); United States v. Conservation Chem. Co., 619 F.Supp. 162, 186 (W.D.Mo.1985) (government response costs include investigations, monitoring, and testing).

Courts have also held that section 104(b) entitles the United States to recover its litigation costs from liable parties. Northeastern Pharmaceutical & Chem. Co., 579 F.Supp. at 851 (“the Court finds that under CERCLA, the defendants are jointly and severally liable for, and the plaintiff is entitled to recover, all litigation costs, including attorney fees, incurred by plaintiff.”); United States v. South Carolina Recycling & Disposal, Inc., 653 F.Supp. 984, 1009 (D.S.C.1984) (holding the United States can recover litigation expenses), aff'd in part and vacated in part in United States v. Monsanto Co., 858 F.2d 160 (4th Cir.1988), cert. denied, — U.S. -, 109 S.Ct. 3156, 104 L.Ed.2d 1019; Conservation Chem. Co., 619 F.Supp. at 186 (following Northeastern Pharmaceutical & Chem. Co.).

Courts have emphasized that liability extends to all response costs. United States v. R.W. Meyer, Inc., 889 F.2d 1497 (6th Cir.1989). These costs also include enforcement costs and administrative expenses. South Carolina Recycling & Disposal, 653 F.Supp. at 1009. In addition, the United States has also been awarded indirect costs. R.W. Meyer, 889 F.2d at 1504. To the extent response or remedial actions are necessary, section 107(a)(4)(A):

contemplates that those responsible for hazardous waste at each site must bear the full cost of cleanup actions and that those costs necessarily include both direct costs and a proportionate share of indirect costs attributable to each site. In essence then, the allocation of the indirect costs to specific cleanup sites effectively renders those costs direct costs attributable to a particular site.

Id. at 1504 (emphasis in original).

Section 107(a)(4)(A) refers to “all costs of removal or remedial action” without specifying the source of the expenditures of the United States. 42 U.S.C. § 9607(a)(4)(A) (Supp. V 1987).

2. Burden of Proof on Response Costs

As stated above, pursuant to section 107(a)(4)(A) of CERCLA, defendants found liable must pay “all costs of removal or remedial actions incurred by the United States Government ... not inconsistent with the national contingency plan.” 42 U.S.C. § 9607(a)(4)(A) (emphasis added). The NCP, 40 C.F.R. § 300-300.71, was promulgated pursuant to section 105 of CERCLA, 42 U.S.C. § 9605. The NCP is the EPA regulation that establishes procedures for selection of response actions. “As long as the actions taken by the government were in harmony with the [NCP], the costs incurred pursuant to those actions are presumed to be reasonable and therefore recoverable.” Northeastern Pharmaceutical & Chem. Co., 579 F.Supp. at 851.

Once the United States has proven that it incurred response costs, the defendants bear the burden of proving that the response costs sought by the United States are inconsistent with the NCP. Northeastern Pharmaceutical & Chem. Co., 810 F.2d at 747.

3. Prejudgment Interest

Prejudgment interest was recoverable even before the 1986 amendments to CERCLA, the Superfund Amendments and Reauthorization Act of 1986 (“SARA”) (signed into law on October 17, 1986). Northeastern Pharmaceutical & Chem. Co., 579 F.Supp. at 852. The SARA amendments to section 107(a) of CERCLA provide that “[t]he amounts recoverable in an action under this section shall include interest on the amounts recoverable.... Such interest 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) (Supp. V 1987). Interest rates are the rates of interest on investments of the Hazardous Substance Superfund. Id.

Prejudgment interest is awarded on amounts incurred prior to SARA. United States v. Northernaire Plating Co., 685 F.Supp. 1410, 1421, aff'd sub. nom. United States v. R.W. Meyer, Inc., 889 F.2d 1497 (6th Cir.1989).

G. General Findings of Fact on United States’ Response Costs

1. In responding to the release or threatened release of hazardous substances in and around the Hardage Site, the EPA and the Department of Justice Land and Natural Resources Division (“LNRD”) incurred both direct and indirect costs. GE 247 at 3; McGeehin Aff. at 3.

2. The direct costs of the EPA included salary expenses of EPA regional and headquarters employees who worked on Hard-age Site response actions, travel, and costs for other services provided by private vendors associated with the work at the Hard-age Site. GE 247. In addition, various EPA contractors provided a variety of investigative, enforcement, and remedial activities at the Hardage Site including site sampling, hydrogeologic studies, aerial photography, and others. GE 247.

3. The LNRD also incurred direct costs in the prosecution of the Hardage case. These costs included “salary expenses for time charged to the Hardage case by LNRD attorneys and paralegals” and “other costs charged directly to the Hardage case,” such as “travel expenses, court reporter fees, and litigation support” expenses. McGeehin Aff. at 3.

4. In addition, both the EPA and the DOJ incurred indirect costs in conjunction with the work performed at the Hardage Site. Indirect costs are costs that are necessary to support response efforts at specific sites, but which cannot be directly identified with a specific site. Menchaca Aff. at 2. The DOJ indirect costs are the type of costs necessary “to support the functioning of LNRD attorneys and paralegals in their performance on individual cases, but which are not charged directly to individual cases.” McGeehin Aff. at 5.

5. These indirect DOJ costs “include, but are not limited to, indirect labor (e.g., attorney and paralegal administrative time, secretarial support, accounting support, record keeping and time keeping), compensated absences, (e.g., vacation, holiday, and sick time), fringe benefits, office space and utilities, supplies, and training.” McGeehin Aff. at 5.

6. The EPA also incurred similar indirect costs, including agency “personnel and program overhead costs such as employee supervision and fringe benefits, program management, administrative support, rent, utilities, telephone, and other indirect costs.” GE 247 at 3.

7. The purpose of an indirect cost determination is to determine the total cost for the work performed by the EPA and the DOJ at a Superfund site, in this case the Hardage Site. VII at 1385; Menchaca Aff. at 3.

8. Methodologies developed by the EPA and the LNRD are used to allocate these indirect costs to specific sites, based on criteria detailed in the affidavits and testimony of William Cooke, Joseph Menchaca, and Patrick A. McGeehin.

H. Additional Findings of Fact — DOJ Direct Costs

1. The LNRD incurred costs in prosecuting eases under CERCLA. McGeehin Aff. at 1-2. These costs included salary expenses, other direct costs, such as travel expenses, court reporter fees, and litigation support. Id. at 3.

2. The LNRD attorneys and paralegals identify their time spent on case and non-case activities. McGeehin Aff. at 2.

3. Under a contract with the DOJ, the accounting firm of Rubino & McGeehin accumulated the costs incurred by the LNRD identified with specific cases. McGeehin Aff. at 1-2.

4. Rubino & McGeehin prepared a summary of the costs incurred by the LNRD in the prosecution of the Hardage case for fiscal years 1987 and 1988 and the first two quarters of fiscal year 1989. McGeehin Aff. at 3 & Attachments 1-4.

5. The summary reflects that DOJ direct labor costs incurred at the Hardage Site during the first two quarters of 1989 totaled $93,934. McGeehin Aff. Attachment 1.

6. The summary also includes other direct costs incurred by the LNRD in private vendor costs for the first two quarters of 1989 in the amount of $831,750. McGeehin Aff. Attachment 4. These costs included expert witness fees, court reporter fees, litigation support, microfilming, and travel. Id.

7. The HSC objected to the summary because it had not had an opportunity to review this documentation.

8. However, the Court's Order Granting Plaintiffs Motion for Partial Summary Judgment on Response Cost Issues (Dec. 8, 1989) (docket sheet No. 2286), granted the United States a declaratory judgment for all future response costs. Therefore, if the United States presents proof that these costs were incurred, it is entitled to recover these costs.

9. The United States incurred costs of at least $93,934 in DOJ payroll expenses in the prosecution of the Hardage case during the first two quarters of fiscal year 1989. McGeehin Aff. Attachment 1.

10. In addition, the United States incurred other direct costs of at least $831,-750 in the prosecution of the Hardage case during the first two quarters of fiscal year 1989. McGeehin Aff. Attachment 4.

I. Conclusions of Law — DOJ Direct Costs

1. The United States met its burden of proving that it incurred DOJ direct payroll costs in the prosecution of the Hardage case during the first two quarters of fiscal year 1989.

2. The DOJ direct payroll costs in the amount of $93,934 are response costs that the United States is entitled to recover from the defendants herein.

3. The United States also met its burden of proving that it incurred other direct costs of the DOJ in the prosecution of the Hardage case during the first two quarters of fiscal year 1989.

4. The DOJ’s other direct costs in the amount of $831,750 are response costs that the United States is entitled to recover from the defendants herein.

5. These direct costs are response costs that the United States is entitled to recover from the defendants. 42 U.S.C. § 9607(a)(4)(A).

J. Additional Findings of Fact — DOJ Indirect Costs

1. The purpose of the LNRD is to prosecute and defend cases. McGeehin Aff. at 5.

2. The indirect costs of the LNRD are “incurred to support the functioning of LNRD attorneys and paralegals in their performance on individual cases, but which are not charged directly to individual cases.” McGeehin Aff. at 5.

3. A list of the types of costs included in DOJ indirect costs is found in Finding of Fact No. 5 in Section X(G) of this Order.

4. The accounting firm of Rubino & McGeehin contracted to compute the indirect costs of Superfund cases for the LNRD from fiscal year 1987 to the present, under a system designed by Rubino & McGeehin. McGeehin Aff. at 5; VI at 1320.

5. The LNRD “system of allocating indirect costs treats all non-case specific costs [of the LNRD] as indirect costs allo-cable to cases.” McGeehin Aff. at 5.

6. The LNRD indirect cost allocation system allocates indirect costs to specific cases through use of indirect cost rates for specific fiscal years. McGeehin Aff. at 5.

7. The LNRD indirect cost rates are calculated by dividing total LNRD indirect costs for a fiscal year (total payments less direct case specific costs) by total LNRD direct labor costs for that fiscal year (i.e., attorney and paralegal direct labor costs) to produce an indirect cost rate for that year. McGeehin Aff. at 5; VI at 1320.

8. Rubino & McGeehin “removed from the indirect cost rate certain costs relating solely to non-Superfund activities, such as costs for which the DOJ is reimbursed by agencies other than EPA.” McGeehin Reb. Decl. at 3.

9. Through the application of the indirect cost rate, only a fraction of LNRD indirect costs is allocated to CERCLA cases. For fiscal year 1987, 73.37% of the total indirect cost was allocated to non-CERCLA cases. Similarly, in fiscal year 1988, 70.92% of the total LNRD indirect cost was allocated to non-CERCLA cases. McGeehin Aff. at 6.

10. “[Ijnteragency agreements between EPA and DOJ dated March 5, 1987 and August 20, 1987 ... provide for reimbursement of indirect costs allocable to Superfund cases, including the Hardage case.” McGeehin R.Decl. at 6.

11. The HSC argued the ratio of indirect to direct costs for DOJ was too high when compared to the private sector. Ma-tunas Decl. at D-ll.

12. However, the direct labor hourly rate for LNRD attorneys for fiscal years 1987 and 1988 for the Hardage case was $19.38. McGeehin Aff. Attachment 5. Were LNRD attorneys to receive higher salaries, the ratio of indirect to direct costs would fall. VI at 1328.

13. The “fully loaded” rates for DOJ attorneys and paralegals working on the Hardage case (“direct labor plus all indirect costs allocated to the case”) of $59.99 for attorneys and $41.98 for paralegals are reasonable in comparison to the private sector. McGeehin R.Decl. at 2.

14. Matunas’ recalculated DOJ indirect cost in Opinion No. 3 of his affidavit did not include office space, postage for correspondence related to the Hardage Site, telephone charges made by DOJ attorneys prosecuting the case, and equipment rental utilized by DOJ attorneys prosecuting the case. McGeehin R.Decl. at 3.

15. General government expenses as defined by OMB Cir. A-87 are excluded from DOJ indirect costs allocated to Superfund cases, including Hardage. McGeehin R.Decl. at 4.

16. Fixed costs as well as variable costs can be allocated as indirect costs. McGeeh-in R.Decl. at 4.

17. The DOJ audit reports “took no exception to the indirect cost rate methodology” developed by Rubino & McGeehin. McGeehin R.Decl. at 5.

18. The LNRD indirect cost allocation system is based on generally accepted accounting principles. McGeehin R.Decl. at 5.

19. The methodology used to calculate DOJ indirect costs is fair and equitable.

20. The DOJ indirect costs claimed for the Hardage case, as reflected in the cost summary included in Attachments 1 through 5 to McGeehin’s Affidavit, were computed through application of the indirect cost rates for fiscal years 1987, 1988, and 1989. McGeehin Aff. at 3.

21. Thus, the total LNRD indirect costs incurred in the Hardage case through fiscal year 1989 are $1,042,489. McGeehin Aff. Attachment 1.

K. Conclusions of Law — DOJ Indirect Costs

1. The United States met its burden of proving that it incurred the DOJ indirect costs in conjunction with the Hardage case. The HSC defendants failed to prove that these DOJ indirect costs are inconsistent with the National Contingency Plan.

2. The indirect costs incurred by the United States in prosecuting the Hardage case, as identified in paragraph 21 above in the amount of $1,042,489, are response costs that the United States is entitled to recover from the defendants herein. 42 U.S.C. § 9607(a)(4)(A) (Supp. V 1987); R.W. Meyer, 889 F.2d at 1504.

L. Additional Findings of Fact — EPA Indirect Costs

1. In 1983, the certified public accounting firm of Ernst & Whinney contracted with the EPA to, among other things, develop a “methodology for calculating the indirect cost of work performed by the EPA under the Superfund program.” Menchaca Aff. at 1.

2. In preparing the indirect cost methodology, Ernst & Whinney considered certain Office of Management and Budget Circulars including A-87, “Cost Principles for State and Local Governments”, and A-21, “Cost Principles for Educational Institutions”. Menchaca Aff. at 2; GE 240. In addition, the methodology was designed to comply with standards issued by the Cost Accounting Standards Board. Menchaca Aff. at 2.

3. The indirect cost methodology developed by Ernst & Whinney for the EPA was described in a report prepared and transmitted to the EPA by letter dated August 26, 1983. GE 241; Menchaca Aff. at 1.

4. The Ernst & Whinney Superfund cost allocation process involved:

(a) Identifying the final cost objective— in this case, work performed by the EPA at a Superfund site. Menchaca Aff. at 3.

(b) Identifying direct costs associated with remedial and response activities at a Superfund site, such as labor costs of EPA personnel working directly on the site. Id.

(c) Identifying “other organizational units that support the people or the process” of remedial or response activities at the site.. An example is the EPA payroll department, which processes information to pay personnel working on the site. Id.

(d) Identifying costs associated with these support services and determining an appropriate basis on which to equitably allocate these costs to the people and processes they support. Id.

(e) Determining a way to allocate these costs to the various Superfund sites on which the personnel worked. Id. at 4.

5. The EPA implemented the methodology developed by Ernst & Whinney to calculate and allocate the indirect costs of work performed by the EPA at Superfund sites. Cooke Aff. at 2.

6. In implementing the Ernst & Whin-ney indirect cost methodology, the EPA identified each organization within the EPA that provided support to the Superfund program. Cooke Aff. at 8.

7. One such organization was the Office of Solid Waste and Emergency Response in the EPA headquarters office, which provides technical assistance, administrative support, and policy guidance. Juszczak Decl. at 1-8.

8. The EPA then gathered financial information from the EPA’s Financial Management System concerning each support organization. Cooke Aff. at 9.

9. The EPA used an allocation statistic to distribute the indirect costs of each organizational unit to Superfund and non-Superfund activities. Generally, this statistic was based on the number of persons employed in each “benefitted” office. Cooke at 9.

10. In allocating indirect costs, the EPA followed a three-step process:

(a) In stage one, the EPA determined, for each fiscal year, the total amount of EPA administrative support costs for EPA headquarters and the 10 regional EPA offices that support CERCLA response actions. The EPA allocated part of the headquarters administrative support costs to each of its 10 regional offices. Cooke Aff. at 11. These costs were then added to each regional office’s administrative costs that support such action.

(b) In stage two, the EPA distributed regional administrative costs to the regional program offices and also distributed stage one costs to regional program offices. Cooke Aff. at 11-12.

(c) In stage three, EPA determined all of the costs of the Superfund program. The EPA then distributed these costs to the site and nonsite activities of the regional Superfund program personnel. Id. at 12.

11. The EPA then calculated an indirect cost rate for each region for each fiscal year by dividing the region’s total site costs as determined by the process described above, by the total number of hours billed by the regional Superfund personnel in a given fiscal year. Cooke Aff. at 13. The indirect cost rates were expressed as dollar amounts to facilitate application of these rates.

12. Because the purpose of the Superfund is to clean up the nation’s hazardous waste sites, generally accepted accounting principles would have permitted the United States to allocate all of the costs of the Superfund program to sites. Cooke Aff. at 13; VI at 1306.

13. The EPA’s indirect cost allocation is conservative because many costs that could have been allocated to sites have been excluded. For instance, capital equipment usage is not allocated to sites, the EPA excludes costs for the EPA Office of Research and Development’s (“ORD”) work on Superfund issues, the EPA excludes non-site-specific costs associated with contractors’ site work, and the EPA’s allocation transfer payments to other federal agencies for Superfund response efforts are excluded. Cooke Aff. at 15-16.

14. OMB Circular A-87 permits the allocation of grantee departmental indirect costs. Menchaca R.Aff. at 2. By analogy, the inclusion of the cost of the Office of the Administrator of the EPA as an allocable indirect cost is consistent with OMB Circular A-87. Id. This inclusion does not represent “ ‘general costs of government’ within the meaning of OMB Circular A-87." Id. at 2-3.

15. Fixed costs as well as variable costs can be allocated as indirect costs. Mencha-ea R.Aff. at 4.

16. The methodology employed to calculate EPA indirect costs allocates to specific sites less than 35% of the indirect costs of the Superfund program. Cooke Aff. at 17.

17. The EPA indirect cost allocation system is based on generally accepted accounting principles. Menchaca Aff. at 2.

18. The methodology used to calculate EPA indirect costs is fair and equitable. Menchaca Aff. at 2; Cooke Aff. at 6,14-15.

19. The indirect cost rates computed by the EPA for EPA Region VI were $66 per hour in fiscal year 1983, $60 per hour in fiscal year 1984, $54 per hour in fiscal year 1985, $53 per hour in fiscal year 1986, and $52 per hour in fiscal year 1987. The provisional rates for fiscal years 1988 and 1989 were $52 per hour in fiscal year 1988, and $52 per hour in fiscal year 1989. Supplemental Joint Statement of Uncontested Facts para. 117, at 37.

20. The number of site-specific hours billed to the Hardage Site by EPA Region VI personnel in program divisions in the fiscal years 1983 through 1988 were: 1983 —587; 1984 — 409; 1985 — 1,105.5; 1986— 1,727.5; 1987 — 1,817; 1988 — 2,468; 1989— 700. Supplemental Joint Statement of Uncontested Facts para. 118, at 37.

21. The EPA’s indirect costs are calculated by multiplying the number of site-specific hours billed by EPA Region VI personnel in program divisions for that year (Fact No. 20) by the indirect cost rate for that year (Fact No. 19).

22. Thus, the total of EPA indirect costs incurred on the Hardage Site through fiscal year 1988 was $473,756.50.

M. Conclusions of Law — EPA Indirect Costs

1. The United States met its burden of proving that it incurred these EPA indirect costs. The HSC defendants failed to prove these EPA indirect costs are inconsistent with the National Contingency Plan.

2. The indirect costs incurred by the United States in performing removal and remedial actions at the Hardage Site, as identified at paragraph 22 above in the amount of $473,756.50, are response costs that the United States is entitled to recover from the defendants herein. See 42 U.S.C. § 9607(a)(4)(A) (Supp. V 1987); R.W. Meyer, 889 F.2d at 1504.

N. Additional Findings of Fact — Rent Charges (“SLUC”)

1. The General Services Administration (“GSA”) administers the real property activities of the United States government through its Management Division of the Public Buildings Service. Van der Walde Aff. at 2. The real property is either owned or leased by the United States.

2. The GSA funds its real property management activities through user charges to “customer” federal agencies, including the DOJ and the EPA, which occupy GSA-controlled space. Van der Walde Aff. at 3.

3. Congress authorized the GSA to collect user charges through the Public Buildings Amendments of 1972 (Public Law 92-313). Van der Walde Aff. at 3.

4. Until 1987, the system used to fix these user charges was called Standard Level User Charges (“SLUC”). With the beginning of fiscal year 1987, the Rent System replaced SLUC. Van der Walde Aff. at 3.

5. Rent System rates are based on five-year cycles. Prior to each cycle, the GSA establishes a base rate for each type of space available in GSA buildings. Van der Walde Aff. at 3. Rates based upon appraisals by professional real estate appraisers are developed for each building. Appraisers compare a GSA building to similar buildings nearby to determine the price “a private landlord would charge a private tenant for GSA space.” Id.

6. The GSA provides its tenants with services including janitorial services, utilities, maintenance, and security. The cost of these services is included in the Rent System. Van der Walde Aff. at 3-4.

7. The GSA rent rates also vary according to the specific finish of the space (e.g., office space, automated data processing space, storage space). Burrell Decl. at 3.

8. The GSA adjusts the rent rates annually to reflect inflation at the building location, as measured by the Consumer Price Index (“CPI”), and changes in operating costs. Van der Walde Aff. at 4.

9. Before implementation, proposed rent rates are subject to review and approval by the Office of Management and Budget. Van der Walde Aff. at 4.

10. All federal agencies are charged rent for all buildings pursuant to the Rent System. Van der Walde Aff. at 6.

11. Rent paid to the GSA by customer federal agencies pays the capital and operating expenses of the GSA’s real property management activities. Van der Walde Aff. at 3.

12. Rent charged to agencies for buildings owned or leased by the United States is established under the above-described appraisal system and represents actual costs to the agencies, including EPA and DOJ. Van der Walde Aff. at 6; Burrell Decl. at 4.

13. For facilities within the DOJ that are located outside the National Capital Region (“NCR”), the actual rent charged by the GSA is passed on through the Justice Management Division directly to the DOJ division that occupies the space. Bur-rell Decl. at 3.

14. The Justice Management Division establishes a DOJ rate for each type of space occupied by a DOJ division such as the LNRD. The DOJ base average rate is determined by totaling the GSA rent charge for each type of space occupied in the NCR and dividing that number by the total number of square feet of the type of space occupied. Burrell Decl. at 3.

15. The final DOJ rate is calculated by adding to the average office space rent charge certain projected DOJ facilities costs, which DOJ is responsible for paying, such as overtime heating, ventilation and air conditioning, overtime guard service, parking, and building maintenance; these are charges that exceed the GSA standard rent charges. Burrell Decl. at 3.

16. Rent and utility costs for space occupied by the EPA and the DOJ personnel who worked on the Hardage Site are “indirect costs.”

17. The space occupied by the DOJ and the EPA was necessary for all of the work these employees did concerning the Hard-age Site.

18. These space costs attributable to the work performed by EPA and DOJ employees concerning the Hardage Site have been allocated through EPA and DOJ indirect cost methodologies. Burrell Decl. at

4.

0. Conclusions of Law — Rent Charges (“SLUC”)

1.The rent component of DOJ and EPA indirect costs is a recoverable cost under section 107(a)(4)(A). 42 U.S.C. § 9607(a)(4)(A) (Supp. V 1987); R.W. Meyer, 889 F.2d at 1504. These indirect costs are attributable to response efforts, because they represent a portion of overhead expenses needed to support EPA and DOJ direct response activities at the Hardage Site. R.W. Meyer, 889 F.2d at 1504.

P. Additional Findings of Fact — Prejudgment Interest

1. The United States filed the Complaint in this action on June 25, 1986. The Complaint requested payment of a specified amount and stated that the United States had incurred, as of the date of the Complaint, “in excess of $1.4 million” in response costs. Id. para. 2, at 2.

2. Since the date of the filing of the Complaint, prejudgment interest has accrued on the costs incurred by the United States in taking removal and remedial actions in response to conditions at the Hard-age Site.

3. Rubino & McGeehin, a certified public accounting firm, calculated prejudgment interest based on the following procedures, bases, and assumptions. For EPA costs:

1. Costs were summarized by the month and fiscal year in which they were incurred based on information provided in the EPA cost summary, dated May 5, 1989 and which is an exhibit to the accompanying Affidavit of Nellie Boone.
2. Costs identified in the EPA summary as incurred in a particular month were assumed to be incurred on the fifteenth (15th) of the month and as a result fifteen (15) days of interest were accrued on those costs for that month, except for those incurred prior to and during June 1986 which accrued five (5) days of interest for June 1986.
3. Interest has been compounded on an annual basis.
4. For purposes of the computation, the cumulative balance is treated as accruing 30 days of interest in each month.
5. The interest rates used are the rates earned by the Hazardous Substance Trust Fund as provided to us by EPA.
6. Interest has been computed from June 25, 1986 through May 31, 1989.

McGeehin S.Decl. at 2-3.

Certain costs listed in the EPA summary were not included in the prejudgment interest calculation as listed in McGeehin’s Supplemental Declaration at page 3. The total of the costs excluded from the EPA prejudgment interest calculation were $793,-976.48. McGeehin S.Decl. at 3. Additional costs totaling $317,672.64 were excluded per the government’s July 3,1990, and July 25, 1990, filings.

For DOJ costs:

1. Costs were summarized by quarter for fiscal years 1987, 1988 and 1989.
2. For fiscal years 1987, 1988 and 1989 costs were assumed to be incurred at the midpoint of the quarter for which they were summarized.
3. Interest has been compounded on an annual basis.
4. Costs identified or assumed as incurred in a particular month were assumed to be incurred on the fifteenth (15th) of the month and as a result fifteen (15) days of interest was accrued on those costs for that month.
5. For purposes of the computation, the cumulative balance is treated as accruing 30 days of interest in each month.
6. The interest rates used are the rates earned by the Hazardous Substance Trust Fund as discussed in the preceding paragraphs.
7. Interest has been computed from the date the costs were incurred through May 31, 1989.

4. The total accrued interest, according to the revised schedule of prejudgment interest for EPA costs, is $469,825.23. McGeehin S.Decl. at 3 (as revised by July 3, 1990, and July 25, 1990, filings).

5. The total accrued interest, according to the revised schedule of prejudgment interest for DOJ costs, is $267,898.18. McGeehin S.Decl. at 4.

6. The prejudgment interest that has accrued on the costs incurred by the United States for response activities at the Hard-age Site, calculated in accordance with the methodology described in the Supplemental Affidavit of Patrick A. McGeehin, is at least $737,723.41. The Court approves this methodology.

Q. Conclusions of Law — Prejudgment Interest

1. The United States has met its burden of proving that it is entitled to prejudgment interest.

2. The United States is entitled to recover prejudgment interest accruing from June 25, 1986, the date of the Complaint, in the amounts of $469,825.23 on EPA costs, and $267,898.18 on DOJ costs, for a total of at least $737,723.41. 42 U.S.C. § 9607(a) (Supp. V 1987).

R. Conclusion

For the reasons set forth above, the United States is awarded its response costs incurred in conjunction with the Hardage Site and this case in the following amounts: the DOJ direct costs for the first two quarters of fiscal year 1989 of $93,934; other direct costs of DOJ for the first two quarters of fiscal year 1989 of $831,750; DOJ indirect costs of $1,042,489; EPA indirect costs of $473,756.50 through the first quarter of fiscal year 1989; and prejudgment interest in the amount of $737,723.41 through May, 1989. The total award of response costs and prejudgment interest is $3,179,652.91.

XI. HSC RESPONSE COSTS AND COUNTERCLAIMS

A. Introduction

When the HSC defendants answered the Complaint in this action on September 8, 1986, they asserted certain counterclaims against the United States. First, the HSC contended that the United States is a liable person under the provisions of 42 U.S.C. § 9607(b)(3) — (4) and requested declaratory judgment concerning the United States’ liability. Next, the HSC counterclaimed for response costs that the HSC defendants incurred in investigating the nature and extent of the contamination at the Hardage Site. Answer and Counterclaims at para. 34 (Sept. 8, 1986) (filing No. 78). The HSC argued that the United States is liable for “all response costs that have been incurred and will be incurred, in a manner consistent with the National Contingency Plan.” Id. In addition, the HSC filed counterclaims for contribution, indemnity, and setoff or re-coupment.

In the Supplemental Joint Statement of Uncontested Pacts, the United States agreed as follows:

Various departments, agencies and in-strumentalities of the United States arranged for disposal or treatment by contract agreement or otherwise of approximately 920,000 gallons of hazardous substances at the Hardage site.

Supplemental Joint Statement of Uncontested Pacts at para. 49. By this statement, the United States stipulated to liability under section 107(a)(3) of CERCLA, 42 U.S.C. § 9607(a)(3).

At trial the HSC asserted inconsistent positions concerning the extent of the United States’ liability in this matter. On the one hand under the HSC’s recoupment counterclaim, the HSC argued the United States must pay 50% of the cleanup costs of Hardage, because an adequate containment remedy could have been implemented years before had the United States not taken over responsibility for the Hardage site from the OSDH. On the other hand, the HSC contends the United States must pay $9.5 million in HSC response costs because all of the HSC’s response activities were necessary to adequately understand the character of the site, to evaluate the release or threat of release from the site, to fill the gaps in the EPA’s data, and to analyze the appropriate alternative containment remedy. In addition, the HSC requests that the Court consider the equities of the case in fashioning relief under section 106(a) of CERCLA. 42 U.S.C. § 9606(a) (1982).

For the reasons set forth below, based on the claims and evidence presented during this phase of the litigation, the Court finds that the HSC should be awarded only $3,716,695.23 in response costs under 42 U.S.C. § 9607(a)(4)(B). In addition, the Court finds the United States should pay its fair share of the HSC’s response costs, the response costs incurred by the United States EPA, and the cost of the remedy ordered based on the amount of waste disposed at the Hardage Site by the departments of the federal government, or 8.36%.

B. Stipulations Regarding HSC’s Counterclaim For Cost Recovery

On November 21, 1989, the parties provided the Court with a written stipulation in this matter. The Court adopts this stipulation as part of its findings and conclusions. Those portions of the stipulation that relate to the HSC counterclaim for cost recovery read:

119. The HSC’s costs for which it seeks recovery have been summarized and recorded under an accrual basis of accounting.
120. The HSC installed and has maintained a chain link fence and warning signs around the Hardage site in accordance with the Stipulation Regarding Installation and Maintenance of a Pence at the Hardage site between the United States and the HSC Defendants filed with the United States District Court for the Western District of Oklahoma on April 29, 1987 (“Fence Stipulation”).
121. Installation of a fence to limit access to and provide security at a Superfund site constitutes a response action under CERCLA.
122. By letter dated January 28, 1988, the completed work pursuant to the fence stipulation has been approved by the United States. [Letter from Mary Ellen McClary to Steven M. Morgan, January 28, 1988].
123. The work performed by HSC Defendants pursuant to the Fence Stipulation is consistent with the National Contingency Plan.
124. The HSC constructed a water line to provide an alternative water supply to residents living near the Hardage site and has provided an alternative water supply to them.
125. Providing an alternative water supply constitutes a response action under CERCLA.
126. The HSC performed certain interim repairs of the soil cover over the Barrel Mound pursuant to the stipulation Regarding Interim Repair and Maintenance of Hardage Site Source Area, which was filed with the Court on February 2, 1988 (“Repair Stipulation”).
127. The HSC performed work at the site in accordance with the Work Plan attached to the Repair Stipulation.
128. The HSC’s work pursuant to the Repair Stipulation constitutes a response action under CERCLA.
129. The HSC’s work pursuant to the Repair Stipulation is consistent with the National Contingency Plan.
130. The HSC performed a Remedial Investigation/Feasibility Study (“RI/FS”) for the second operable unit at the Hardage site to determine the existence and extent of contamination at the site, to determine the existence and extent of any thre'at to public health or welfare or the environment posed by the migration of any contamination at the site, and to determine and evaluate alternatives for any appropriate remedial response actions necessary to address the second operable unit at the Hardage site.
131. The conduct of a remedial investigation/feasibility study is a response action under CERCLA.
132. The United States and the HSC Defendants entered into a Partial Consent Decree governing the performance of the Remedial Investigation/Feasibility Study for the second operable unit, which was entered by the Court.
133.The HSC has conducted a number of site investigations, studies, tests, and data-gathering efforts at the Hardage site.

Supplemental Joint Statement at 37-38.

C. Witnesses

Three principal HSC witnesses supported its request for private party response costs under section 107(a)(4)(B). The witnesses and their topics included: Richard Bost and Benjamin Costello, the necessity of investigative activities performed by the HSC to design an appropriate remedy for Hardage and the remedial measures taken to protect the public health; and Thomas Matunas and Benjamin Costello, the costs of the HSC’s response activities and the internal controls over the HSC’s costs.

Two principal United States witnesses testified concerning the necessity and reasonableness of the costs claimed by the HSC, Dr. Kirk W. Brown and John B. Robertson. Marc A. Jewett’s testimony addressed the accuracy and quality of certain HSC field studies and investigations. Finally, Patrick A. McGeehin offered opinions regarding the inclusion of litigation costs in the HSC’s response cost claim and the sufficiency of the HSC’s cost documentation.

To attempt to support the HSC’s recoupment counterclaim and equity argument, the HSC presented several witnesses, including Mark S. Coleman, John A. Cherry, J. Mark Schmittle, Richard Bost, and Benjamin Costello.

D. Exhibits

The exhibits offered by the HSC to support its response cost claim included: DE 6-9, 11-14, 19-22, 49, 109, 111-36, and 146-53. The United States introduced the following exhibits on this issue: GE 281a-p, 283-87.

Exhibits offered by the HSC to support its recoupment counterclaim and equity argument included: DE 1-52, 142-45.

E. Contentions of the Parties

As to its response cost claim, the HSC contends the United States, as a person liable under section 107(a) of CERCLA, must pay all of the $9.5 million in HSC response costs at the Hardage Site. The HSC argues the costs in question are those the HSC incurred in investigating and remediating the site. The HSC urges that the studies and investigations were necessary to accurately characterize the Hard-age Site and to design the appropriate remedy for Hardage, and therefore, the costs of such activities are “necessary” and “consistent with the national contingency plan.” 42 U.S.C. § 9607(a)(4)(B) (Supp. V 1987). Costs of other interim remedial measures were necessary to protect the public health, argues the HSC. Finally, the HSC stresses that it maintained a system of internal controls that assured that the costs are accurate and reasonable.

As to its recoupment counterclaim and equity argument, the HSC contends the Court should limit the relief awarded against the HSC and apportion a substantial share of the Hardage Site cleanup obligations to the United States. Finally, the HSC argues the fault for much of the site’s condition and the need for much of the expense lies with the United States for preventing remediation of the site in 1982, for failing to take steps to protect human health and the environment, and for failing to adequately investigate the site.

In response to the HSC’s cost claim, the United States contends the tests conducted by the HSC were designed to support the HSC’s litigation position concerning HSC’s containment remedy proposal. The United States asserts that the EPA’s approval was necessary for all response actions taken after the date of the enactment of the SARA amendments, and that only four activities of the HSC were not precluded by this approval requirement. As to all other costs, the United States argues that the HSC will be unable to demonstrate it received EPA approval. Finally, the United States contends the HSC’s response activities were neither necessary nor consistent with the NCP, and that the HSC failed to meet the detailed NCP public comment requirements of 40 C.F.R. § 300.71.

In response to the HSC’s recoupment counterclaim, the United States responds that the HSC failed to show a nexus between the relief sought by the United States and the transaction or occurrences that the HSC’s recoupment counterclaim asserts. Finally, the United States argues it should pay only its fair share of the HSC’s response costs.

F. Legal Discussion

1. Private Party Response Costs

As discussed in Section X of this Order, CERCLA provides for the recovery from liable persons of “all costs of removal or remedial action incurred by the United States ... not inconsistent with the national contingency plan.” 42 U.S.C. § 9607(a)(4)(A) (Supp. V 1987). The CERC-LA also contemplates the recovery of private party response costs from liable persons as follows: “any other necessary costs of response incurred by any other person consistent with the national contingency plan.” 42 U.S.C. § 9607(a)(4)(B) (Supp. V 1987).

The CERCLA does not define “necessary costs of response.” T & E Indus., Inc. v. Safety Light Corp., 680 F.Supp. 696, 705 (D.N.J.1988). However, “response” under CERCLA means “remove, removal, remedy, and remedial action, all such terms (including the terms ‘removal’ and ‘remedial action’).” 42 U.S.C. § 9601(25) (Supp. V 1987) (footnote omitted). For CERCLA purposes, “remove” and “removal” mean: 42 U.S.C. § 9601(23) (Supp. V 1987). Included in the definition are specific removal actions such as security fencing or other measures to limit access, and the provision of alternative water supplies. Id.

[T]he 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 activities 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 CERCLA defines “remedy” or “remedial action” as:

[T]hose actions consistent with permanent remedy taken instead of or in addition to removal actions in the event of a release or threatened release of a 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 to 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 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. The term includes the costs of permanent relocation of residents and businesses and community facilities where the President determines that, alone or in combination with other measures, such relocation is more cost-effective than and environmentally preferable to the transportation, storage, treatment, destruction, or secure disposition offsite of hazardous substances, or may otherwise be necessary to protect the public health or welfare; the term includes off-site transport and offsite storage, treatment, destruction, or secure disposition of hazardous substances and associated contaminated materials.

42 U.S.C. § 9601(24) (Supp. V 1987).

Removal actions are primarily those intended for short-term or interim responses, and remedial actions are generally considered long-term or permanent remedies. City of New York v. Exxon Corp., 633 F.Supp. 609, 614 (S.D.N.Y.1986).

The act authorizes organizations of private parties to assist or conduct site response activities by:

(1) Organizing responsible parties;
(2) Initiating negotiation or other cooperative efforts;
(3) Apportioning costs among liable parties;
(4) Recommending appropriate settlements to the lead agency;
(5) Conducting the RI/FS in accordance with this Plan;
(6) Evaluating and recommending appropriate remedies to the lead agency;
(7) Implementing and overseeing response actions;
(8) Obtaining assurances for continued site maintenance from responsible parties; and/or
(9) Recommending sites for deletion after completion of all appropriate response action.

40 CFR § 300.71(b) (1989).

For purposes of cost recovery under section 107 of CERCLA, a response action is consistent with the NCP if the person taking the response action:

(i) Where the action is a removal action, acts in circumstances warranting removal and implements removal action consistent with § 300.65.
(ii) Where the action is a remedial action:
(A) Provides for appropriate site investigation and analysis of remedial alternatives as required under § 300.68;
(B) Complies with the provisions of paragraphs (e) through (i) of § 300.68;
(C) Selects a cost-effective response; and
(D) Provides an opportunity for appropriate public comment concerning the selection of a remedial action....

40 CFR § 300.71(a)(2)(i) & (ii) (1989).

By the provisions of section 104 of CERCLA, the President may allow a potentially responsible party to carry out a remedial action, conduct the remedial investigation, or conduct a feasibility study, if the President decides the job can be done properly by the PRP. Allied Corp. v. Acme Solvents Reclaiming, Inc., 691 F.Supp. 1100, 1109 (N.D.Ill.1988). However, where the President or a delegate has “initiated a remedial investigation and feasibility study for a particular facility under [CERCLA], no potentially responsible party may undertake any remedial action at the facility unless such remedial action has been authorized by the President.” 42 U.S.C. § 9622(e)(6) (Supp. V 1987).

If, notwithstanding the EPA’s involvement with a site, “a PRP undertakes a remedial action, its action will be deemed inconsistent with the NCP.” Acme Solvents Reclaiming, 691 F.Supp. at 1109. “However, if the EPA ‘authorizes’ the remedial action, the action will not (if otherwise consistent) be inconsistent with the NCP.” Id. “Passive acquiescence” by the EPA does not constitute sufficient authorization. Id. “Surely Congress did not intend under Section 122(e)(6) that, once the EPA initiates a remedial investigation and feasibility study, PRP’s are free to undertake their own chosen form of remedy and then recover costs in federal court....” Id. at 1110.

Attorneys fees and costs of litigation are not recoverable by a private litigant under CERCLA. T & E Indus., 680 F.Supp. 696, 707 (D.N.J.1988). Whereas section 104(b) of CERCLA provides for the recovery of attorney fees and litigation costs by the United States, no analogous portion of the statute entitles a private party to recover for legal action taken. Id. at 708; Northeastern Pharmaceutical & Chem. Co., 579 F.Supp. at 851. While private parties “may bring an action for recovery of response costs, they may not bring an action to enforce CERCLA’s clean-up provisions against another private entity. Thus, private parties do not incur ‘enforcement costs’ as contemplated by CERCLA.” T & E Indus., 680 F.Supp. at 708 n. 13.

If tasks are performed to assist counsel in their defense of the litigation, “the Court is not aware of any authority which would enable those parties to recover such costs as response costs.” United States v. Conservation Chem. Co., 628 F.Supp. 391, 406 (W.D.Mo.1985).

2. Recoupment

The doctrine of recoupment “permit[s] a transaction which is made the subject of [a] suit by a plaintiff to be examined in all its aspects, and [a] judgment to be rendered that does justice in view of the one transaction as a whole.” Rothensies v. Elec. Storage Battery Co., 329 U.S. 296, 299, 67 S.Ct. 271, 272, 91 L.Ed. 296 (1946). The three criteria for a recoupment counterclaim are: (1) it must arise out of the same transaction or occurrence that is the subject of the government’s suit; (2) it must seek relief of the same kind or nature as that sought by the government; and (3) it must be purely defensive, i.e., it must seek only to defeat the government’s claim and not seek an affirmative recovery of damages. Frederick v. United States, 386 F.2d 481, 488 (5th Cir.1967); United States v. Yonkers Bd. of Educ., 594 F.Supp. 466, 469 (S.D.N.Y.1984). See generally 6 C. Wright, A. Miller & M. Kane, Federal Practice and Procedure § 1427 (2d ed. 1990). According to the standards applied in the Tenth Circuit, the elements of a claim for recoupment are:

[W]hen the sovereign sues it waives immunity as to claims of the defendant which assert matters in recoupment— arising out of the same transaction or occurrence which is the subject matter of the government’s suit, and to the extent of defeating the government’s claim but not to the extent of a judgment against the government which is affirmative ... but the sovereign does not waive immunity as to claims which do not meet the “same transaction or occurrence test” nor to claims of a different form or nature than that sought by it as plaintiff nor to claims exceeding in amount that sought by it as plaintiff.

Frederick, 386 F.2d at 488 (footnotes omitted); cited in Jicarilla Apache Tribe v. Andrus, 687 F.2d 1324, 1344 (10th Cir.1982).

3.Equity Under CERCLA

Section 106(a) of CERCLA provides the Court with jurisdiction to “grant such relief as the public interest and the equities of the case may require.” 42 U.S.C. § 9606(a) (1982). In fashioning the remedy and apportioning responsibility among the parties in this case, the Court is guided by the “equities of the case.” United States v. A & F Materials Co., 578 F.Supp. 1249, 1259 (S.D.Ill.1984). The HSC urges the Court to consider all of the facts concerning the Hardage Site in arriving at a fair, just, and lawful outcome of this case.

G. Findings of Fact — HSC Response Costs

1. During the years the Hardage Site was operated as a toxic waste disposal site, from 1972 to 1980, the OSDH and the Oklahoma City-County Health Department inspected the Hardage Site on at least 24 separate occasions. Supplemental Joint Statement para. 57, at 14-30.

2. These inspectors reported widely varying conditions, with problems initially centered around pits filled to capacity and the potential for overflow. DE 10 at 3.1.

3. In 1974, with funding from the National Science Foundation, students from the University of Oklahoma made a site investigation of contaminated soils and water within the Hardage permit area. Results from their investigations indicated chrome contamination of the soils north of the main pit area at the Hardage Site. GE 216 at 1-4.

4. In 1976, the OSDH requested that Mr. Hardage install groundwater monitoring wells in the southwest drainage. The wells were originally four inches in diameter. Eventually, the operator installed 13 wells. DE 10 at 3.1; GE 216 at 1-5.

5. Following the installation of the groundwater monitoring wells, the OSDH sampled these wells on 12 different occasions between August 13, 1976, and August 16, 1982. Supplemental Joint Statement para. 57, at 14-22.

6. In addition, the OSDH also collected surface water samples on seven occasions, took soil and sediment samples seven different times, tested water wells around the Hardage Site on 11 occasions, and tested tap water from farms in the vicinity on 10 occasions. In addition, the OSDH collected raw milk samples from an adjacent dairy on one occasion. Supplemental Joint Statement para. 57.

7. In February of 1980, Tim Baker, a groundwater geologist, and Kenneth Burns, an environmental program specialist, both of the OSDH Industrial and Solid Waste Service, issued their preliminary report into the contamination of the water supplies in the Criner Area, concluding:

3. Soil samples taken have shown contaminated material is being transported from the disposal site by runoff which is not adequately contained on the site.
4. The contaminated material is being deposited in the Alluvium of North Cri-ner Creek which does create potentially hazardous conditions for water supplies in this area.

DE 121 at 1.

8. Investigations of the Hardage Site by the EPA began in 1979 and included the following samplings and inspections:

(a) February and March 1979. “EPA sampled milk, fish, tap water, surface water, and liquids at the site.” Supplemental Joint Statement para. 57.32, at 17.

(b) June 27, 1979. Ralph Harkins of EPA Region VI, accompanied by Donald A. Hensch, director, Industrial Waste Division, H.A. Caves, chief of industrial and solid waste service, Jim Rolin, fish and wildlife ranger, Jerry Miller, county sanitarian, and a television news crew from KWTV, Channel 9 in Oklahoma City, inspected the asbestos disposal at the Hard-age Site. Supplemental Joint Statement para. 57.36, at 17; DE 10 app. A.

(c) August 15, 1979. EPA and Oklahoma State Department of Health personnel obtained nine soil, water, and waste samples and inspected the site. The samples were analyzed for metals and organics, and photos were taken. DE 10 app. A; Supplemental Joint Statement para. 57.40, at 18.

A water sample from the interceptor trench was analyzed and several organic pollutants were identified,, including .009 mg/1 of 1,1,1 — tri-chloroethane. GE 217 vol. I, at 3-3.

(d) August lb, 1980. Thomas Smith of Ecology & Environment performed off-site sampling for the EPA. Three samples were taken from off-site drainage pathways, which were analyzed for metals and organics. DE 10 app. A; Supplemental Joint Statement para. 57.59. Phenols, chlorinated pesticides, and PCB’s were detected in these samples. GE 217 vol. I, at 3-3.

(e) October 1, 1980. Thirteen off-site samples were taken from off-site drainage and domestic water wells and analyzed for metals and organics, and photos were taken. DE 10 app. A; Supplemental Joint Statement para. 57.62, at 20.

Three sediment samples indicated total phenols of <0.3 mg/kg and lead ranging from 6.3 to 25.2 mg/kg. GE 217 vol. I, at 3-3.

(f) June 1981. A draft interim report concerning the Hardage Site was submitted to EPA by Dames & Moore. This report summarized the site activities and conditions. This report indicated sediment contamination from the ponds on the southwest part of the site and from the borrow ditch on the southern boundary of the property. GE 217 vol. 1, at 3-4.

(g) March 23 — April 18, 1982. Imre Sekelyhide and other FIT employees conducted detailed on- and off-site sampling of the Hardage Site. Twenty-nine samples were collected between March 23-24, 1982; six domestic wells were sampled from March 23-24, 1982. Ten monitoring wells were drilled by Sheperd Testing and Engineering Co. of Norman under the direction of Jerry Thornhill, a hydrogeologist at the EPA’s Ada branch, between March 30 and April 2, 1982. Soil borings and monitoring well samples were collected from each new monitoring well. DE 10 app. A; Supplemental Joint Statement para. 57.78, at 21.

Variable concentrations of phenols, 1,1,1 —trichloroethane, methylene chloride, and benzene were observed in all of the EPA monitoring wells. Extensive testing of Corley’s domestic well occurred in 1982. Reported concentrations of 1,1,1 — trichloro-ethane ranged from .0001 to .0127 mg/1, and benzene concentration ranged from less than .0002 to .0021 mg/1. GE 217 vol. I, at 3-10.

(h)August 16, 1982. Ecology & Environment (FIT) performed a second sampling of 10 groundwater samples for the wells drilled by FIT in March 1982. DE 10 app. A.

9. In 1979, EPA inspections of the Hardage Site indicated poor waste management practices posing potential threats to the public health and welfare and the environment. DE 10 at 11.1.

10. On September 8, 1980, the DOJ filed suit in Hardage I, on behalf of the EPA against the Hardage Site owner pursuant to section 7003 of the Resource Conservation and Recovery Act (“RCRA”), 42 U.S.C. § 6973. DE 10 at 11.1. In June 1982, the EPA and the DOJ amended the complaint to include allegations of violations and requests for relief under sections 106 and 107 of CERCLA, 42 U.S.C. §§ 9606 & 9607.

11. On December 13, 1982, Judge West of this district entered findings of fact and conclusions of law in Hardage I. The Court found contamination of soil and groundwater at the Hardage Site as well as releases of contaminants into the air. The Court’s Order concluded the Hardage Site was dangerous and found Mr. Hardage individually liable for remedial action. Id.

12. The EPA continued to study the Hardage Site. During 1983 and 1984 the EPA conducted the following studies:

(a) A site investigation conducted for the EPA by Douglas Kent in 1983, which included an electrical resistivity survey of the North Criner Creek alluvium, construction of outcrop stratigraphic sections, fracture measurements, and a laboratory hydraulic conductivity test. Supplemental Joint Statement para. 57.92, at 22.

(b) A site investigation conducted by CH2M Hill for the EPA in 1984 which included: drilling 20 borings and completing 19 as pvc-cased monitoring wells; sampling surface water, ground water, source areas, and test pits; conducting a magnetometer survey and boring study of source areas in the main pit and sludge mound; and conducting bedrock packer and geo-technical tests. Supplemental Joint Statement para. 57.104, at 23.

13. Subsequent to the site closure, several organic chemicals disposed of on-site were found in local drinking water supplies downgradient from the site. These chemicals included: 1,1 dichloroethylene, 1,1,2 trichloroethane, tri-chloroethylene, tetrachloroethylene, and is (2-chlorethyl) ether, which are suspected carcinogens, and 1,2 dichloroethylene and 1,1 dichlorethane, which are EPA Hazardous Wastes and Priority Toxic Pollutants. GE 217 vol. I, at 1-9 to 1-10.

14. In addition, the EPA compiled available records from the site operations including daily and monthly site logs of wastes received, waste manifests, and disposal plans and records filed with the State of Oklahoma by generators and transporters of waste to the site. DE 10 at 11.2.

15. As a result of the compilation of these records, numerous PRPs were identified. DE 10 at 11.2.

16. These records revealed that in all, between 18 million and 20 million gallons of waste were disposed of at the Hardage Site. DE 10 at 2.0.

17. The records also revealed that the general types of waste accepted at the Hardage Site included: oil recycling wastes, acids, caustics, lead, chromium, cyanide, arsenic, pesticides, and PCBs. DE 10 at 3.2.

18. The EPA determined the contaminants that posed an immediate threat through the groundwater were chlorinated solvents, including: 1,2-dichloroethane, 1,1,2-trichloroethane, 1,1-dichloroethene, tetrachloroethene, and trichloroethene. The EPA also determined that other compounds such as lead, chromium, PCBs, and toxaphene were present on the site and would pose long-term or permanent hazards due to their persistence in the environment. DE 10 at 3.2.

19. On January 3, 1983, CH2M Hill, the EPA’s contractor at the Hardage Site, released its Draft Feasibility Study Work Plan. Supplemental Joint Statement para. 57.97, at 23.

20. On January 26, 1983, Joan K. Leav-itt of the OSDH “requested assistance from the EPA to conduct remedial response action at the Hardage Site.” Supplemental Joint Statement para. 57.98, at 23.

21. On July 18, 1983, CH2M Hill completed a draft work plan and statement of work for a feasibility study for the Hard-age Site. Supplemental Joint Statement para. 57.100, at 23.

22. Pursuant to the CH2M Hill Feasibility Study Work Plan, CH2M Hill conducted additional testing of the Hardage Site and accumulated the results of all of the above listed tests and inspections that had been conducted by the OSDH, the EPA, and others. The results of the data accumulation and testing summaries are found in CH2M Hill’s Field Investigation and Data Summary Report. GE 217.

23. CH2M Hill issued its Field Investigation and Data Summary Report on the Royal Hardage Industrial Hazardous Waste Site in May 1985. GE 217.

24. The NCP directs the EPA to perform a “remedial investigation/feasibility study” (“RI/FS”), as appropriate. 40 CFR § 300.68(d) (1989), DE 10 app. C, at C-19.

25. Based upon the already extensive data compiled on the site, the EPA determined that a discrete remedial investigation of the Hardage Site was not appropriate. DE 10 app. C, at C-19. The EPA believed the aggregate of prior studies and data on the Hardage Site, when combined with the CH2M Hill Field Investigation and Data Summary Report, would in fact constitute a record of substantial equivalence to a discrete Remedial Investigation. Therefore, the EPA decided to move directly to the Feasibility Study requirement of CERCLA. DE 10 app. C, at C-20; 40 CFR 300.68 (1989).

26. At the time the Feasibility Study was committed by the EPA for the Hard-age Site, the EPA enforcement policy documents, which recommend participation of PRPs in the RI/FS where appropriate, had not been promulgated by the EPA. In addition, the EPA had not yet completed the search for PRPs. For this reason, PRPs were not involved in the Feasibility Study from the outset. DE 10 app. C, at C-38.

27. On or about December 12, 1984, the EPA notified numerous companies, pursuant to section 104 of CERCLA, 42 U.S.C. § 9604, of their status as PRPs pursuant to section 107 of CERCLA, 42 U.S.C. § 9607. Supplemental Joint Statement para. 64, at 31.

28. The EPA also decided to divide the feasibility study process into two phases, or operable units — “source control” and “groundwater/offsite.” DE 8 para. 2. The division was made based on technical information about the site and the criteria present in the NCP. As noted in the Feasibility Study, the EPA believed at the time the division was made, and continued to believe, that a substantial quantity of wastes remained in or near the original location and were not contained by adequate barriers, and that a remedy for source control would be cost-effective and consistent with a permanent remedy at the site. DE 10 at C-16.

29. Beginning in September of 1985, the HSC began to try to convince the EPA that the HSC should assume control of a full RI/FS for the Hardage Site. DE 1. This offer was renewed by the HSC in October and December 1985, January 1986, and finally in March 1986. DE 2, 3 & 4.

30. These offers came when the EPA had already conducted its own investigations and was about to issue its own Feasibility Study on the Source Control Phase. GE 216.

31. The EPA saw no reason to revisit “that substantial part of [the] investigation and feasibility study already performed,” and rejected the HSC’s offer to perform a comprehensive RI/FS on the entire Hard-age Site. DE 8.

32. On February 20, 1986, the EPA issued CH2M Hill’s Feasibility Study Source Control on the Royal Hardage Industrial Hazardous Waste Site. GE 217.

33. The Court finds that given the volume of data that the EPA had accumulated as reported in its Field Investigation and Data Summary Report issued in May 1985, together with the fact that this Court had already determined in 1982 that the Hard-age Site was dangerous and contaminated, the EPA’s decision to proceed to a feasibility study and to reject the HSC’s request to do a comprehensive RI/FS for the Hardage Site was reasonable.

34. When the HSC was unsuccessful in convincing the EPA that the HSC should conduct a full RI/FS, it contracted with ERM-Southwest on March 27, 1986, to critique the feasibility study done by the EPA. GE 281-C at 2-2. Five working days later, a draft report was transmitted to the HSC. On April 11, 1986, just 15 days after being hired, ERM-Southwest issued its Review and Critique — Source Control Feasibility Study. DE 122.

35. Early on, the HSC seized on the remedy theory and litigation strategy it was going to pursue. On May 15, 1986, ERM-Southwest issued its “Proposal for Studies to Determine the Feasibility of an In-Place Closure”. GE 281-C. The intent of the study was to address only the feasibility of the in-place closure. Id. at 3-1. ERM concluded that legal action with the EPA might be necessary to overturn a non-technically based decision on EPA’s part to choose incineration or some other inappropriate remedy. This report was attorney work product as shown in Government Exhibit No. 281-C.

36. Since the inception of this action, a substantial difference of opinion has existed between the EPA and the HSC as to what constitutes “adequate data.” DE 10 app. C. In addition, a substantial difference of opinion has existed between the parties as to the amount of testing necessary to assess the dangers and conditions at the site.

37. The HSC presents a cost claim for HSC response costs in the amount of $9,530,984.72. DE-153 at p. 60 of 80. Included in HSC’s claim are costs of performing interim remedial measures at the Hard-age Site, together with the costs of site investigations, studies, tests, and data-gathering efforts at the Hardage Site. Id.

38. Subject to the reserved objections based upon the effect of the Consent Decree, the United States agrees the costs for the following HSC response activities are acceptable: (a) security fence, (b) mound slope and site repairs, (c) alternative water supply, (d) well plugging, (e) access agreements, and (f) site maintenance. Comments of U.S. on HSC Defendants’ Summary of Claimed Response Costs (Dec. 13, 1988) (filing No. 2308).

39.The HSC performed the following response actions at the Hardage Site under CERCLA to protect the health and welfare of the nearby residents and the environment, consistent with the NCP:

(a) Constructed and maintained a security fence around the Hardage Site in accordance with the Stipulation Regarding Installation of a Fence at the Hardage Site, dated April 29, 1987. Schmittle Decl. at D-38; Costello Decl. at D-5; X at 1908; Supplemental Joint Statement paras. 120, 121 & 123.

(b) Performed interim repairs of the soil cover over the barrel mound, pursuant to the Stipulation Regarding Interim Repair and Maintenance of the Hardage Site Source Area, dated February 2, 1988 (“Repair Stipulation”). Supplemental Joint Statement paras. 126, 128 & 129.

(c) Constructed a water line and provided an alternative water supply to nearby residents. Supplemental Joint Statement paras. 124 & 125.

(d) Plugged several damaged EPA wells and several large open boreholes to prevent actual or potential movement of affected groundwater to lower, unaffected areas. The EPA approved these activities. Costello Decl. at D-5; X at 1908-9; Schmittle Decl. at D-39.

(e) Entered into access agreements with local landowners in order to undertake interim remedial measures and to investigate conditions at the Hardage Site. Costello Decl. at D-6; X at 1909.

(f) Performed maintenance as necessary to ensure the safety of personnel working at the site and to control erosion. Costello Decl. at D-6; X at 1909.

40.The HSC defendants incurred the following necessary costs of response that are consistent with the NCP:

(a) Interim remedial measures:
(1) Security fence $104,385.52
(2) Barrel mound repair 107,985.76
(3) Alternative water supply 122,190.30
(4) Plugging of wells 126,835.05
(b) Access agreements 14,600.00
(c) Site maintenance 20,698.63

41. In addition, the HSC conducted extensive site investigations, studies, tests, and data gathering efforts at the Hardage Site. Supplemental Joint Statement para. 133, at 38.

42. The bedrock studies and expert panel field investigations identified in the HSC cost claim were performed solely to support the HSC’s litigation position, i.e., that a relatively inexpensive in-place containment remedy for the Hardage Site would be appropriate. X at 1942-45, 1973-80; Jewett R.Aff. at 6-7; Robertson R.Aff. at 2; GE 281-C at 1-1, 2-6; DE 122. The HSC’s expert opinion on the necessity of such studies was limited to that which was necessary to support the HSC’s preferred remedy. X at 1941-42. The expert panel field investigations were necessary only because the final confirmatory bedrock study failed to establish conclusively that the HSC’s preferred in-place containment remedy would work. X at 1944.

43.The bedrock studies and expert panel field work were performed entirely at the direction of the HSC’s litigation counsel. X at 1980-90, 1993-97. The evidence also showed:

(a) Litigation counsel was closely involved in the day-to-day design and implementation of the bedrock studies. X at 1980.

(b) During the bedrock studies, HSC’s contractor ERM-Southwest worked “for the lawyers such that any work we did was the result of instructions from litigation counsel.” X at 1981.

(c) Litigation counsel was heavily involved in technical decisions on testing such as: (1) directing the number and orientation of borings, (2) the decision not to complete a monitoring well or perform packer tests at boring B-13, and (3) the decision not to perform packer tests at DH-1. X at 1984-89, 2026.

(d) The timing of the final confirmatory bedrock study was motivated by the HSC’s desire to present its first remedy to the Court. X at 1942.

(e) The HSC’s counsel admitted the expert panel field work by ERM-Southwest was “strictly litigation-oriented.” X at 1994.

(f) ERM-Southwest described the expert panel field work as litigation support. X at 1997; GE 281-G.

44. The HSC presented no authority authorizing costs of “EPA oversight” as private party response costs. Activities involving EPA oversight were designed to enhance the HSC’s litigation efforts by casting doubt on the efficiency of the EPA’s efforts. See Costello Deck at D-10; X at 1910. The defendants’ EPA oversight expenses are duplicative, unnecessary, and not consistent with the NCP.

45. The barrel mound characterization studies were conducted contemporaneously with the expert panel field work, and like that work, were deemed “strictly litigation-oriented” by HSC counsel. X at 1994; Jewett R.Aff. at 6-7; Robertson R.Aff. at 2. An HSC witness, Mr. Bost, acknowledged the barrel mound studies were performed at least in part at the request of litigation counsel and in preparation for trial, yet the HSC presented no evidence demonstrating it had attempted to separate litigation related activities from nonlitigation activities.

46. The HSC presented no evidence to show whether the drummed sampling waste disposed of was collected during the HSC, EPA, or other sampling activities. Accordingly, the HSC failed to meet its burden of proof that the costs of “drum disposal” were “necessary” recoverable response costs within the meaning of section 107 of CERCLA.

47. The design of the HSC’s proposed “remedial design” constituted a litigation-related activity because:

(a) IT Corp., the principal contractor for the remedy design work, described its work for the HSC as “[t]rial remedy basis design.” X at 1938-40; GE 281-L & 286.

(b) IT Corp.’s contract was with HSC’s litigation counsel. X at 1938-40; GE 286.

(c) IT Corp.’s contract with HSC’s litigation counsel required IT to submit all reports in draft form to litigation counsel for review and approval. GE 286.

(d) This contract called for IT to develop a “trial remedy design.” GE 286.

48. The HSC presented insufficient evidence to prove that the costs of its hydrological/hydrogeological studies are recoverable response costs because they, too, were designed to seek support for the HSC’s preferred in-place containment remedy. X at 1942-43.

49. The HSC performed a Remedial Investigation/Feasibility Study (RI/FS) for the second operable unit pursuant to a Partial Consent Decree entered by the Court. The RI/FS evaluated alternatives for any appropriate actions necessary to address the second operable unit, management of migration. Supplemental Joint Statement paras. 130, 131 & 132. The total cost requested by the HSC in connection with the RI/FS was $4,184,142.08.

50. Certain portions of the cost of the second operable unit RI/FS are excluded because:

(a) ERM invoices in the amount of $200,-000 that appear in the HSC’s cost claim are not recorded in ERM’s internal summary of the second operable unit RI/FS costs. X at 1921-22; GE 281-P.

(b) The second draft RI/FS activities submitted by the HSC to the EPA were not requested by the EPA. X at 1919; DE 14.

(c) Meta-Trace invoices in the amount of $200,282.68 involved work for the first operable unit RI/FS. X at 1923.

(d) Invoices totaling $50,000 involve chain of custody litigation support. GE 281-P.

(e) Costs for other work performed for litigation activities included $69,127.93 for monthly progress reports and project coordination, and $40,137.07 for HSC RI/FS review meetings. GE 281-P.

51. An HSC witness, Mr. Bost, conceded that the second operable unit work included litigation-oriented activities. X at 1998-99; GE 281-H.

52. On the basis of the unproved costs, the HSC cost claim for second operable unit RI/FS should be reduced to $3,220,-000. United States’ Comments on HSC Summary of Claimed Response costs.

53. ERM-related claims represent more than $7 million of the $9.5 million response cost claim of the HSC. X at 1969. ERM’s representative, Mr. Bost, twice described ERM’s client as the law firm of McKinney, Stringer & Webster and not the HSC. The contract between the HSC and ERM provides that the work performed will be utilized “for Counsel’s preparation for existing litigation” and that all such work shall be deemed “confidential and privileged.” GE 285 at 2.

54. Mr. Costello’s general opinion that direct litigation costs were removed from the HSC cost claim (X at 1925-27) is contradicted by:

(a) The inclusion in the cost claim of numerous invoices for services, including those from Mr. Costello’s company, which contain charges for services such as “litigation” or “depositions.” X at 1931-35; GE 281-K, 281 — Q; McGeehin R.Decl. at 5.

(b) The inclusion in the cost claim of entire categories of expenses that were designed solely to bolster the HSC’s litigation position, as set out in the above findings.

(c) Mr. Costello’s and Mr. Matunas’ testimony that the decisions regarding what costs to include and exclude in the cost claim — including what costs were litigation-related — were made by the HSC’s litigation counsel. X at 1871-76, 1915.

55.The opinions of Mr. Costello and Mr. Bost that the costs claimed by the HSC in its cost summary are reasonable and necessary in order to protect the public health and welfare and to monitor, assess, and evaluate conditions at the site (Costello Decl. at B-l; Bost Deck at D-4) were disproved by:

(a) Mr. Costello’s refusal to testify as to what types of costs might be “necessary,” as that term is defined in CERCLA. X at 1941.

(b) the fact that Mr. Costello reviewed and passed judgment on his own company’s cost figures as well as those of others. X at 1926-28, 1930-33.

(c) Mr. Costello’s concession that expenses, including a dinner, that do not meet the criteria set out in CERCLA are included in the cost claim. X at 1949-53; GE 281-M, 281-N, 281-0. Mr. Costello also included in the HSC response cost request a dinner he had with HSC lawyer Coldiron. GE 281-M. Mr. Costello also included a dinner in Chicago for the expert panel members that cost $1,000. GE 281-0. Mr. Costello claimed this expense actually represented the charge for a meeting room in addition to a meal. X at 1959. However, the charge receipt for the dinner contains a straight 15% tip on the entire amount, as would most meals (GE 281-0), and the invoice has other charges explicitly listed as “meeting charges.” GE 281-N at 3.

(d) Mr. Costello’s clarification that, in rendering his opinion that the HSC’s costs were necessary costs of response, he ignored the statutory standard and included all costs incurred as “normal costs of business.” X at 1950.

(e) The rebuttal testimony of Dr. Brown, Mr. Jewett, and Mr. Robertson that many of the claimed costs were in fact unnecessary or otherwise improper. Brown R.Aff. at 3, 8-9; Jewett R.Aff. at 6-7; Robertson R.Aff. at 2-4.

(f) The findings set out above indicating that the cost claim contains a substantial amount of costs related solely to litigation.

(g) Other examples of improper costs for such extravagant meals appear in other invoices introduced into evidence. GE 281-Q at 2.

56. The volume of site investigations, tests, studies, and samples performed by the HSC was necessary only to support the HSC’s litigation position concerning an in-place containment remedy.

H.Conclusions of Law — HSC Response Costs

1. The HSC costs of a security fence, mound slope and site repairs, alternative water supply, well plugging, access agreements, and site maintenance are “necessary costs of response ... consistent with the national contingency plan.” 42 U.S.C. § 9607(a)(4)(B) (Supp. V 1987).

2. The HSC failed to meet its burden of demonstrating that its claim for the cost of bedrock studies, expert panel field investigation, oversight of EPA work, mound characterization studies, drum disposal, remedial design, and hydrological/hydrogeo-logical studies are “necessary costs of response ... consistent with the national contingency plan.” 42 U.S.C. § 9607(a)(4)(B) (Supp. V 1987).

3. Only $3,220,000 of the HSC’s costs of the second operable unit RI/FS are “necessary costs of response ... consistent with the national contingency plan.” 42 U.S.C. § 9607(a)(4)(B) (Supp. V 1987).

4. Costs borne primarily to support the HSC’s litigation position are not “necessary costs of response ... consistent with the national contingency plan.” 42 U.S.C. 9607(a)(4)(B) (Supp. V 1987); United States v. Conservation Chem. Co., 628 F.Supp. 391, 406 (W.D.Mo.1985).

5. Approval by the EPA is necessary for remedial actions only. 42 U.S.C. § 9622(e)(6) (Supp. V. 1987); Versatile Metals, Inc. v. Union Corp., 693 F.Supp. 1563, 1575-76.

6. The necessary costs of response incurred by the HSC totaled $3,716,695.23.

7. The United States is liable for only 8.36% of the awarded HSC response costs. 42 U.S.C. § 9607(a)(4)(B) (Supp. V 1987).

8. The United States is not liable for prejudgment interest on any HSC response costs.

9. The United States is liable for 8.36% of the future response costs, if any, incurred by the HSC defendants that are approved by the Court pursuant to section 107(a)(4)(B) of CERCLA, 42 U.S.C. § 9607(a)(4)(B).

10. The United States is liable for 8.36% of the EPA response costs, past and future, incurred by the United States.

I. Findings of Fact — Recoupment Counterclaim

1. The HSC failed to demonstrate that the conditions at the Hardage Site would have been mitigated if the OSDH remedy had been implemented. The OSDH remedy was not a permanent remedy. An HSC witness, Dr. Cherry, conceded that groundwater, as well as surface flow, serves as a pathway of containment migration from the source areas. XI at 2121, 2128; VIII at 1612.

2. The United States’ action arises primarily out of the disposal and subsequent release of hazardous substances from the Hardage Site from 1972 through 1980. Complaint para. 6, at 3.

3. The HSC’s counterclaim for recoupment purports to be based on alleged negligence by the EPA in connection with its remediation of the site after 1980.

4. The EPA’s alleged negligence did not arise from the same transaction as the disposal of waste at the Hardage Site.

5. The HSC’s claim arises from different conduct, was committed by different parties, and arose over different periods of time than those involved in the United States’ case-in-chief.

J. Conclusions of Law — Recoupment Counterclaim

1. The United States has “no affirmative duty to consult with [the] parties before undertaking [CERCLA] response actions.” United States v. Mottolo, 695 F.Supp. 615, 628 (D.N.H.1988).

2. The HSC failed to show a nexus between the relief sought by the United States and the transactions or occurrences the HSC’s recoupment counterclaim asserts. United States v. 2,116 Boxes of Boned Beef, 726 F.2d 1481, 1490-91 (10th Cir.1984). Specifically, the HSC failed to demonstrate that it is entitled to any re-coupment because of the EPA’s cleanup activities at the Hardage Site.

K. Findings of Fact — Equities of the Case

1. Of the 20 million gallons disposed of at the Hardage Site, the United States and its various agencies arranged for disposal or treatment of approximately 920,000 gallons or 4.6% of the waste at the Hardage Site. Supplemental Joint Statement para. 49, at 13.

2. The HSC has presented no evidentia-ry basis for assessing the United States for 50% of the costs of the remedy at the Hardage Site.

3. The federal share of liability at the Hardage Site should be allocated on the basis of the United States’ contribution to the site.

4. The federal share of liability at the Hardage Site is 8.36%. This figure is determined by taking 920,000 of the total 11 million gallons generated by the remaining financially viable parties (thus excluding “orphan shares” from the total waste). Supplemental Joint Statement paras. 48-51.

5. The United States is liable for 8.36% of the costs of the remedy ordered at this site.

L. Conclusions of Law

1. The United States’ portion of the remedy at the Hardage Site is 8.36% of the costs of the remedy ordered at this site. 42 U.S.C. § 9606(a).

2. This resolves the United States’ liability in this lawsuit.

M. Conclusion

For the reasons set forth above, the HSC is awarded a total of $3,716,695.23 in response costs. The United States is liable for only 8.36% of the HSC response costs. The United States is liable for only 8.36% of the remedy ordered for this site. This Order resolves all of the United States’ liability in this lawsuit.

XII. ADDITIONAL FINDINGS OF FACT AND CONCLUSIONS OF LAW

1. Under the circumstances in this case the remedy is ordered pursuant to section 106(a) of CERCLA, 42 U.S.C. § 9606(a). The Court has held a trial de novo to determine the remedy that best protects the public health and welfare and the environment. See Order on Motion to Restrict Review (filed Sept. 9, 1988) (filing No. 1434), and attached rulings.

2. The administrative record offered by the EPA to support its proposed remedy is inadequate because:

(a) The remedy issues in this action cannot be resolved on the basis of an administrative record. See id.
(b) The Record of Decision dated November 22, 1989, supports a remedy that the government acknowledges is different than the remedy proposed in the Partial Consent Decree and different than the trial remedy described by the government’s witnesses. Limiting review to the administrative record therefore would require rejection of the remedy proposed, and advocated at trial, by the United States.

3. The remedy proposed by the EPA, as described in its Remedy Report of October 13, 1989, and by the government’s trial witnesses, would require significant, further design work before it could be implemented. The further design work could result in material changes to the remedy advocated at trial or could reveal that major components of the proposed remedy are infeasible or not cost effective. Indeed, the government’s remedy has already undergone dramatic changes during the course of this litigation. The United States failed to prove by a preponderance of the evidence, and failed to persuade the Court on the trial record as a whole, that the EPA’s preferred remedy is appropriate for the Hardage Site.

4. Had the Court limited its review of remedy selection issues to the EPA’s administrative record, the Court would find that the EPA’s selected remedy is arbitrary, capricious, and an abuse of discretion.

5. There would be no demonstrable benefit either to public health and welfare or to the environment from implementing the added components proposed as part of the EPA’s remedy. The benefits claimed for those components are offset by the substantial risks associated with their implementation. Bost Deck D-7 to -11; Cherry Deck at D-22; Harris Deck at C-40.

6. To the extent the NCP standards are applicable or may be considered by the Court, the HSC’s proposed remedy best satisfies those standards.

7. The HSC’s proposed remedy is based upon adequate data and analysis. See 40 C.F.R. § 300.68(i) (1989).

8. The HSC’s proposed remedy is more cost-effective than the EPA’s proposed remedy. See 40 C.F.R. §§ 300.68(g)(1), 300.68(i) (1989).

9. The HSC’s proposed remedy as modified is “feasible for the location and conditions of the release,” and presents “a reliable means of addressing the problem.” 40 C.F.R. § 300.68(g)(2) (1989).

10. The HSC’s proposed remedy as modified would not cause “significant adverse effects,” while the EPA’s remedy presents serious risks to workers, residents, passersby, and has limited environmental benefits. 40 C.F.R. § 300.68(g)(3) (1989).

11. The HSC’s proposed remedy as modified will generate fewer vapor and dust emissions that will migrate off site, and therefore the HSC’s proposed remedy will minimize the risks of future exposures remaining after implementation of the remedy. See 40 C.F.R. § 300.68(h)(2)(iv) (1989).

12. The HSC’s proposed remedy as modified is the more cost-effective remedy that best “mitigates and minimizes threats to and provides adequate protection of public health and welfare and the environment.” 40 C.F.R. § 300.68(i)(l) (1989).

13. The HSC’s proposed remedy as modified “attains or exceeds applicable or relevant and appropriate Federal public health and environmental requirements that have been identified” for the site. 40 C.F.R. § 300.68(i)(l) (1989).

14. The EPA excavation remedy could lead to uncontrolled vapor emissions, or present such serious risks to workers that it would have to be halted. The HSC remedy components, which largely duplicate the portions of the EPA remedy other than excavation and soil vapor extraction, do not present similar risks of failure. The EPA remedy therefore carries with it a greater “potential for future remedial action costs if the alternative remedial action in question were to fail.” CERCLA § 121(b)(1)(F), 42 U.S.C. § 9621(b)(1)(F) (Supp. V 1987).

15. The EPA’s excavation remedy could lead to greater “potential threat[s] to human health and the environment associated with excavation, transportation, and redis-posal, or containment” of wastes, toxic vapor emissions, and fugitive dust emissions than the HSC’s proposed remedy. CERC-LA § 121(b)(1)(G), 42 U.S.C. § 9621(b)(1)(G) (Supp. V 1987).

16. The State of Oklahoma opposes the EPA’s proposed excavation remedy. The OSDH’s support of the HSC’s proposed remedy is a factor that weighs in favor of the HSC’s remedy. See CERCLA § 121(f), 42 U.S.C. § 9621(f) (Supp. V 1987).

17. The HSC’s proposed remedy as modified is more “cost effective” than the EPA’s proposed remedy. It will achieve greater reduction of any risks that the site may present to the public health and welfare and the environment and will cost substantially less. See CERCLA § 121(a), (b)(1), 42 U.S.C. § 9621(a), (b)(1) (Supp. V 1987).

18. The HSC’s proposed remedy as modified is more “relevant and appropriate under the circumstances presented” at the Hardage Site. CERCLA § 121(d)(1), 42 U.S.C. § 9621(d)(1) (Supp. V 1987). The EPA remedy, on the other hand, involves potentially dangerous excavation and waste handling activities and also involves the use of soil vapor extraction technology at a site that may not be well suited for that technology.

19. The closure plan proposed by the State of Oklahoma in 1982 was an “interim solution.” In the Court’s view, it would only “mitigate the problem ... on the short-run.” Ill at 597-99. The closure plan would not have been an adequate remedial action for the Hardage Site. V at 1155-56.

20. Both the EPA’s proposed remedy and the HSC remedy as modified and adopted by the Court must be monitored in perpetuity. V at 1027.

21. The V-trench and southwest interceptor systems, as proposed by the EPA and the HSC, must be maintained and operated indefinitely. VIII at 1594-95.

22. Both the EPA remedy and the HSC remedy would require institutional controls to restrict access to affected ground water in the alluvium. V at 1180; III at 681.

23. Pursuant to: the Court’s Judgment and Order of November 10, 1988; the Court’s orders of May 23, 1990, and June 11, 1990, respectively, adjudging defendants CATO Oil and Grease Co., Dal-Worth Industries, Inc., Double Eagle Refining Co., J.O.C. Oil Exploration Co., Inc., Oklahoma National Stockyards Co., and Rockwell International Corp., jointly and severally liable for United States response costs; this Court’s Order of May 28, 1990, finding Kerr-McGee Corp. and Kerr-McGee Refining Corp., jointly and severally liable for United States response costs; this Court’s Judgment of June 16, 1989, entering L & S Bearing Company’s stipulation of liability for United States response costs; and this Court’s Order adjudging defendant U.S. Pollution Control, Inc., jointly and severally liable for United States response costs, the following parties have been found to be jointly and severally liable for any injunctive relief ordered under section 106 of CERCLA, 42 U.S.C. § 9606, with respect to the Hardage Site, and for any judicial determination of the United States’ costs ordered pursuant to section 107 of CERCLA, 42 U.S.C. § 9607, remaining after a determination of the extent of liability of the plaintiff under sections 106 and 107 of CERCLA:

AT & T Technologies, Inc.
Advance Chemical Distribution, Inc.
Allied-Signal, Inc.
Ashland Oil, Inc.
Atlantic Richfield Co.
Sam L. Bishkin, individually and d/b/a Eltex Chemical and Supply Co.
Borg-Warner Corp.

CATO Oil and Grease Co.

Dai-Worth Industries, Inc.
Double Eagle Refining Co.

Texaco Refining and Marketing, Inc.
Texas Instruments, Incorporated
UOP, Inc.
The Uniroyal Goodrich Tire Co.
United States Pollution Control, Inc.

24. The implementation of the remedy ordered for the Hardage Site will require access to and use of the Hardage Site and certain tracts of land near the Hardage Site. GE 2 at 3-109; III at 680-81; Bost Deck at D-7; R. Davis R. Aff. sec. 3.34, at 15.

25. The defendants adjudged liable shall commence negotiations with the owners of nearby properties to acquire the easement interests and property tracts needed for the remedial action and institutional controls ordered to implement, operate, and maintain the Hardage Site remedy. If the property tracts or necessary easement interests cannot be acquired through negotiated agreement within 90 days from the date of this Order, the defendants shall apply to the Court for such relief as is necessary. The defendants are not required to acquire any property owned by Mr. Hardage.

26. The Hardage Site and the acquired easement and other property interests shall be dedicated solely to the remedial activities ordered by the Court, and as necessary shall be restricted for other purposes. Use restrictions on the Hardage Site and other acquired property interests shall be recorded with the Recorder of Deeds of McClain County, Oklahoma, and shall run with the land, binding all successors in interest to these properties.

27. The Court began the preparation of this Order without utilizing transcripts from the trial of the case. As trial transcripts were examined by the Court following the trial of this matter, the Court found it helpful to include certain transcript citations in its findings. The citations to the record contained in this Order are intended only to be representative of the evidence in support of the finding. In preparing its findings, the Court relied on the record as a whole (including but not limited to the evi-dentiary citations contained in this Order), the Court's own notes and draft findings prepared during trial, and the parties’ various proposed findings. In some instances the Court has included no evidentiary citations, reflecting the Court’s recollection of the record as a whole.

28. Any finding of fact contained in this Order that should more properly be considered a conclusion of law shall be deemed a conclusion of law for purposes of this Order. Any conclusion of law contained in this Order that should more properly be considered a finding of fact shall be deemed a finding of fact for purposes of this Order.

XIII. CONCLUSION

For the reasons set forth above, the Court rejects the United States’ proposed remedy for the Hardage Site and accepts the HSC defendants’ proposed remedy, with the indicated modifications. A judgment consistent with this Order, approved as to form only by all counsel, is attached.

EXHIBIT A

ORDER

Filed Jan. 20, 1989

A. INTRODUCTION

On January 9, 1989, the Court conducted a hearing on defendants’ motion to reconsider the Court’s November 23, 1988 order permitting interlocutory appeal. For the reasons set forth on the record at the hearing, the Court withdrew its previous certification order, dated November 23, 1988, and entered a new order denying the government’s September 14, 1988 motion to permit interlocutory appeal pursuant to 28 U.S.C. § 1292(b). See Minute Order issued January 11, 1989.

This case has had a lengthy history of litigation resulting in extensive discovery and numerous motions and other pleadings. When faced with a lengthy, complex trial such as this one, the Court has found it to be beneficial to require the parties to do some additional preparation for trial. Certain procedures used by the Court serve to streamline the issues and delete unnecessary presentation of evidence. Accordingly, no continuances or departures from the following schedule will be permitted.

B. FINAL WITNESS AND EXHIBIT LISTS

In addition to the witness and exhibit lists called for by this Court’s previously issued scheduling order, plaintiff is to submit to defendants by 6:00 p.m. Monday, August 21, 1989 its final witness and exhibit list in this matter, setting forth those witnesses it actually intends to call in its case-in-chief in the actual order of anticipated appearance. The listing shall be filed with the Court on the same day. The listing shall be in conformance with the sample attached to this Order. This format also requires plaintiff to identify the specific exhibits to be introduced or discussed in connection with each witness, whether the witness has been deposed, and a time estimate for the direct examination of each witness.

The exhibits referenced in the list shall have been previously marked, identified, and made available to opposing counsel so that the exhibit number on the chart will sufficiently identify the exhibit for opposing counsel.

Any witnesses or exhibits which surface at the time of trial but which have not been identified or made available for deposition or inspection by opposing counsel during the discovery period shall not be permitted at trial.

By September 4, 1989, defendants are to file and submit to plaintiff a similar witness and exhibit list for their case-in-chief.

Hostile witnesses called by either side in the cases-in-chief are partially exempted from this rule in that affidavits, as well as the complete listing of exhibits to be used in connection with such witnesses, are not required. The hostile witnesses must, however, be identified as hostile witnesses on the chart filed with the Court along with their anticipated order of appearance and time estimate of their examination, as well as the other items called for on the attached chart.

C.STIPULATION OF UNCONTESTED FACTS

The parties shall enter into a comprehensive written stipulation of all uncontested facts in such form that it can be introduced as the first evidence at the trial. The comprehensive stipulation should include all facts intended to be proved by either side which the other side is not going to dispute either by a controverting witness or by cross-examination. It should include preliminary or background facts, as well as ultimate facts if they are not disputed. It is suggested that counsel for plaintiff list all facts intended to be proved at trial including those assumed to be in dispute. Defense counsel can then delete those facts to be controverted and add any additional facts they intend to prove. Counsel for plaintiff can then delete any additional facts which will be controverted. This technique should result in a stipulation of all uncontested facts, as well as a list of all contested facts. The parties may utilize their contentions and their drafts of the final pretrial order as a starting point for this stipulation. The stipulation must, of course, be organized in some logical order so that it will be intelligible when read by the Court as the first trial evidence. If the admissibility of some uncontested fact is challenged, the objecting parties, and the grounds for objection, must be stated. This stipulation will be filed with the Court by August 11, 1989.

D. DEPOSITION PROCEDURE

As to all depositions which the parties expect to offer at the time of trial the following procedure is adopted. The parties will designate all depositions to be read into evidence and attempt to agree as to those portions to be read. It is suggested that a four-color system of designation be used. Plaintiff can use one color, e.g., green, to designate portions it desires to read. Defendants can use a second color, e.g., red, to indicate those portions designated by plaintiff to which defendants object, stating the grounds for the objections. A third color, e.g., blue, can be used by defendants to designate any additional portions they desire to read, and plaintiff can use a fourth color, e.g., brown, to indicate portions designated by defendants to which plaintiff objects, stating the grounds for the objections. The Court will rule in advance of their use at trial. The depositions will be filed with the Court by November 24, 1989.

E. EXPERT WITNESSES

On October 2, 1989, plaintiff and defendants will file affidavits of each of their respective expert witnesses, if any. The affidavits shall contain the following: (a) an identification and description of the spe-cifie areas or fields in which the witness will be tendered as an expert; (b) an identification and description of each exhibit which will be introduced or discussed in connection with the expert’s testimony with respect to each such exhibit, with an appropriate evidentiary foundation supporting the introduction and/or discussion of each such exhibit; (c) a separate listing and summary of every opinion to be rendered by the expert during his or her testimony; (d) a separate listing of the basis for each opinion set forth in (c) above. The expert’s curriculum vitae should be attached to the affidavit of the expert witness as an exhibit, and shall be in written form suitable for introduction into evidence. This vitae shall cover every item supporting the qualifications of the expert witness’ testimony.

Because this is a non-jury trial, the expert witness affidavits and their attachments, subject to any proper objections, will be received in evidence as the direct examination of the experts at trial. The attorney sponsoring any expert witness will be given no more than thirty (SO) minutes to highlight or emphasize any portions of the expert’s testimony (though no new matters outside the affidavit may be raised absent a showing of just cause and compelling circumstances). The expert witness will then be tendered for cross examination.

Objections to any matters contained in the affidavits shall be filed by November 3, 1989. Affidavits of rebuttal witnesses, if any, shall be filed by November 10, 1989. Objections to rebuttal affidavits shall be filed by November 20, 1989.

F.NON-EXPERT WITNESSES

On October 2, 1989, plaintiff and defendants will file affidavits of all their remaining witnesses to be called in their cases-in-chief, with the exception of hostile witnesses.

The affidavits shall be prepared in accordance with the requirements set forth in Section E above with respect to any exhibits to be introduced and/or discussed in connection with each witness, and shall set forth the entire proposed direct examination of the witness.

Subject to objections, the affidavits will be received in evidence as the direct examination of the witnesses at trial. The attorney sponsoring any non-expert witness on direct examination will be given no more than fifteen (15) minutes to highlight or emphasize any portion of the witness’ testimony under the procedure set forth in Section E above. The witness will then be tendered for cross examination.

Objections to any matters contained in the affidavits shall be filed November 3, 1989. Affidavits of rebuttal witnesses, if any, shall be filed by November 10, 1989. Objections to rebuttal affidavits shall be filed by November 20, 1989.

G. DISCOVERY CUTOFF

Discovery cutoff as to liability issues is May 15, 1989. As to other issues the discovery cutoff is August 1, 1989. The parties may conduct any additional discovery by agreement after those dates provided that any such discovery conducted after those dates will not be offered or submitted to the Court in connection with any disposi-tive motions filed.

All other deadlines established by this Court’s previous scheduling order remain intact unless altered below.

H. DISPOSITIVE MOTIONS — PLAINTIFF AND DEFENDANTS

(1) Liability Issues

Dispositive motions shall be filed by June I. 1989. Responses thereto shall be filed by June 30, 1989. Replies, if any, shall be filed by July 14, 1989.

(2) Other Issues

Dispositive motions shall be filed by September 1,1989. Responses thereto shall be filed by September 29, 1989. Replies, if any, shall be filed by October 13, 1989.

Although the Court has permitted the parties to extend the previous discovery cutoff dates, this Court will not allow any agreed upon extensions of discovery to adversely impact the dispositive motion schedule set forth above. Had the Court not permitted the parties to extend discovery, the dispositive motion schedule set forth above would have been well after the termination of discovery. Accordingly, no extension of the dispositive motion schedule will be permitted based upon a claim that discovery is still ongoing. Similarly, the Court will not permit any dispositive motions to be supplemented by discovery conducted after the filing of dispositive motions and/or the responses.

I.DISPOSITIVE MOTIONS — THIRD-PARTY DEFENDANTS

The third-party defendants previously filed an application for an order permitting them to conduct limited discovery and to file dispositive motions prior to the trial of phase I and phase II issues. That application was denied by a short written order issued July 14, 1988. See docket sheet entry no. 1297.

The Court, however, has reconsidered the position of the third-party defendants and hereby modifies the July 14,1988 order to permit limited discovery and the filing of dispositive motions prior to the November 27, 1989 remedy trial, for any third-party defendants who desire to do so. This is entirely optional.

Those third-party defendants who desire to file dispositive motions prior to the remedy trial will adhere to the following schedule:

(1) From March 22 through April 28, 1989 the third-party defendants may conduct discovery relative to the dispositive motions.

(2) The dispositive motions shall be filed by May 19, 1989.

(3) From May 22 through June 29, 1989, third-party plaintiffs may conduct discovery relative to any dispositive motions which are filed.

(4) The responses to the dispositive motions shall be filed by July 14, 1989.

(5) Replies, if any, shall be filed by July 21, 1989.,

(6) A hearing on any dispositive motions filed by Third-parties in accordance with this schedule will be held August 25, 1989 at 8:00 a.m.

J. SITE VISIT

The parties shall make appropriate arrangements for the Court and the Special Master to visit the Hardage disposal site on Monday, March 27, 1989.

K. SETTLEMENT CONFERENCE

A two-day settlement conference will be conducted April 26-27, 1989.

L. FINAL PRETRIAL ORDER, PRETRIAL STATUS CONFERENCE, OPENING STATEMENTS AND TRIAL

The trial is set on the Court’s November 27, 1989 trial docket. The Final Pretrial Order shall be approved by all parties and submitted to the Court by November 17, 1989. A final pretrial conference will be held November 24, 1989 at 8:00 a.m. All proposed findings of fact, conclusions of law and trial briefs shall be filed by November 24, 1989. The parties may, if they desire, make opening statements on November 24, 1989. Given the submission of trial briefs and proposed findings, opening statements will be limited to thirty (30) minutes per side.

M. TOTAL AMOUNT OF TIME TO BE DEVOTED TO TRIAL

This case had been the subject of various and shifting trial estimates by the parties. On February 1, 1988, in the status report signed by counsel for all parties, and submitted to the Court, the parties made the following representation to the Court:

VII. ESTIMATED TRIAL TIME:

Phase II Remedy: 30 trial days Status Report filed February 1, 1988.

In the briefs submitted to the Court of Appeals on the now-aborted petition for interlocutory appeal the defendants stated:

The Government agreed in principle with the Defendants in late November of [1988] to propose a scheduling order that included a 52-day trial for the entire “remedy phase” of the case.

Opposition of Generator and Transporter Defendants-Respondents to Application of the United States to Permit Interlocutory Appeal at 14, filed December 11, 1988, in US.A. v. Hardage, No. 88-8090 in the Tenth Circuit. See also Affidavit of Robert D. Tomlinson, attached as Exhibit A to the Memorandum in Support of Motion of Hardage Steering Committee Defendants for Reconsideration of Order Allowing Interlocutory Appeal, filed December 1, 1988 in this Court.

The government did not dispute that such an agreement had been reached. Moreover, at the hearing on January 9, 1989, counsel for the government indicated that adoption of the procedures set forth in this order would cut the actual trial time by approximately one-half, and endorsed the affidavit, deposition and stipulation procedures outlined above. The parties’ previous trial estimates assumed six (6) hours of trial every trial day, an estimate this Court exceeds on a regular basis.

The Court believes that it should be entitled to rely on the trial estimates the parties provided to the Court, and further believes that from the statements of the parties concerning the nature of their cases, that much of the proffered evidence in this ease is overlapping and duplicative. Accordingly, based on the previous representations of counsel, the Court has determined that it will allocate no more than thirty days to hear the total trial of this case. No departures from this total time period will be entertained or granted. This is the amount of time the parties previously told this Court it would take to try this case, and more time than necessary to try the case under the 52-day estimate provided to the Court of Appeals, when reduced by the procedures endorsed by the parties in this case.

The Court will, at a later date, issue further time restraints within the 30-day time period, to be determined after reviewing the submissions of the parties called for by this Order. For purposes of trial preparation at this time, however, counsel should assume that the government will be permitted 14-days to present its case-in-chief, the defense will be given 14-days to present its case-in-chief, the government will be given one day of rebuttal and the defense one day of sur-rebuttal. These limitations, of course, are subject to the Court’s authority to curtail any evidentiary presentation upon proper objection.

Moreover, if it appears to the Court that any of the parties have taken unreasonable positions with respect to requiring proof of matters not in dispute, refusing to sign stipulations which eliminate unnecessary proof, or challenging the evidentiary foundation of exhibits or testimony without adequate basis, the Court reserves the right to add to or subtract from any party’s allocated evidentiary presentation, with the understanding that the total trial time of 30 days will remain unchanged. Given the fact that the government bears the burden of proof in this matter, the Court will not hesitate to reduce the defendants’ eviden-tiary presentation if dilatory tactics are employed.

A typical trial day will begin at 8:45 a.m. and end at 5:15 p.m. There will be one hour and fifteen minutes for both lunch and the accommodation of other docket matters, as well as two twenty (20) minute breaks, one in the morning session and one in the afternoon session. Consistent with the parties’ previous trial estimates, the parties are assured that there will be at least six (6) hours of trial on each of the thirty (30) trial days.

The time taken to argue all objections made by a party which are overruled by the Court shall be deducted from the objecting party’s time. Time for objections which are sustained will be deducted from the time of the proponent of the evidence. Otherwise, the time spent in non-evidentia-ry presentations will be charged to the requesting party.

The total time devoted to cross examination of any witness will be limited to the time which would be necessary to present the witness’ relevant and necessary direct examination in the absence of the affidavit procedure adopted by this Court. This determination will be made by the Court. If unusual circumstances require cross examination to exceed the time which would have been devoted to the relevant and necessary direct examination, as determined by the Court, the excess time will be charged to the cross examining party.

The parties are directed to confer each evening prior to the next day of trial and to jointly review the exhibits to be offered during the direct examination of the upcoming witnesses in an effort to eliminate, wherever possible, objections to the anticipated exhibits. The presentation of each witness should begin with an announcement of the exhibits which may be received in evidence without objection.

Fed.R.Evid. 403 recognizes the power and duty of the Court to exclude cumulative evidence or evidence which consumes more time than its probative value justifies. See United States v. Algie, 503 F.Supp. 783, 793 (E.D.Ky.1980), rev’d on other grounds, 667 F.2d 569 (6th Cir.1982). Rule 611 directs the Court to “exercise reasonable control over the mode and order of interrogating witnesses and presenting evidence, so as to (1) make the interrogation and presentation effective for the ascertainment of the truth, [and] (2) avoid needless consumption of time.” In short, it is fundamental that a court has the power and duty to manage its docket and the individual cases before it to “secure fairness in administration, [and] elimination of unjustifiable expense and delay.” Fed.R. Evid. 102. As stated by the Court in United States v. Reaves, 636 F.Supp. 1575, 1578 (E.D.Ky.1986):

There is an unnamed party in every lawsuit — the public The public’s right to a “just, speedy, and inexpensive determination of every action” is infringed, if a court allows a case, civil or criminal, to preempt more than its reasonable share of the court’s time.

The courts have discretion to place reasonable time limits on the presentation of evidence to prevent undue delay, waste of time, or needless presentation of cumulative evidence. See Johnson v. Ashby, 808 F.2d 676 (8th Cir.1987); MCI Communications v. American Tel. & Tel. Co., 708 F.2d 1081, 1171 (7th Cir.1983). As stated by the court in Flaminio v. Honda Motor Co., Ltd., 733 F.2d 463, 473 (7th Cir.1984): “[I]n this era of crowded district court dockets federal district court judges not only may but must exercise control over the length of trial....” See also United States v. Reaves, 636 F.Supp. 1575 (E.D.Ky.1986); SCM Corp. v. Xerox Corp., 77 F.R.D. 10, 13-15 (D.Conn.1977). As stated by one commentator: “All jury trials should have time limits less than the time now required.” Kirst, Finding a Role for the Civil Jury in Modern Litigation, 64 Judicature 333, 337 (1986).

Under the circumstances of this case, the Court has no hesitation in placing a thirty day time limitation on the total length of this trial. Indeed, the Court believes that if this matter is diligently pursued by all counsel, it either will not be tried at all or will be tried in less than thirty days, due to the streamlining measures initiated by stipulations and this Order. The Court regrets, however, having to schedule this trial during the 1989 holiday season. Unfortunately, the month of December is traditionally the only time the Court could conduct a continuous thirty-day trial without seriously affecting the Court’s regular docket.

N. CONCLUSION

The Court will utilize the parties’ submissions as a basis for resolving many of the disputed evidentiary issues in this case prior to trial. This Order is entered without prejudice to the Court entering sanctions pursuant to Rule 16(f) or other provisions of the Federal Rules of Civil Procedure for failure to comply with pretrial scheduling orders. See Roy v. American Professional Marketing, Inc., 117 F.R.D. 687 (W.D.Okla.1987); Roberts v. McCrory, 693 F.Supp. 998 (W.D.Okla.1987); Lindsey v. United States, 693 F.Supp. 1012 (W.D.Okla.1988).

As stated previously, no continuances or departures from the schedule set forth in this Order will be permitted.

IT IS SO ORDERED THIS 20th DAY OF JANUARY, 1989.

EXHIBIT B

SUPPLEMENTAL JOINT STATEMENT OF UNCONTESTED FACTS

Filed Nov. 21, 1989

COME NOW the plaintiff and the defendants, pursuant to the court’s pretrial scheduling order of January 20, 1989, as modified on July 27, 1989, and file this supplemental joint statement of uncontested facts. The following changes are reflected in this document:

a) Paragraphs 92 through 97 in the original Statement were deleted as they were duplicative of the current paragraphs 81 through 87.
b) The number 63 was changed to 57 in Paragraphs 55 and 56.
e) The word “conductivity” in Paragraph 113 was replaced with the word “transmissivity”.
d) Paragraph 108 has remained the same. It should be deleted from HSC’s Contested Facts.
e) The Volumes category on page 38 reflects recent agreement by the parties.
f) Stipulation Number 53 has been added.

GENERAL

1. The Royal N. Hardage industrial waste site (“the site”) is located in McClain County, Oklahoma, approximately 15 miles southwest of Norman, Oklahoma and lh mile west of the community of Criner, Oklahoma.

2. The site is located on the 160 acre quarter section in the southwest corner of Section 24, T6N, R4W.

3. The site is bounded on the south by State Highway 22, a gravel road on the west, on the east by three small farm ponds, and on the north by the northwest quarter of Section 24, and it was within this general area that hazardous waste operations were conducted by Royal N. Hard-age between 1972 and 1980.

4. The site constitutes a “facility” within the meaning of 42 U.S.C. § 9601(9).

SITE HISTORY-PERMITTING

5. On September 12, 1972, Royal N. Hardage applied to the Oklahoma State Department of Health (OSDH) for a permit to construct, operate, and maintain an Industrial Hazardous Waste Land Disposal facility on a portion of his property near Criner, McClain County, Oklahoma.

6. With his permit application of September 12, 1972, Hardage included a letter which outlined a general plan for managing the site which included the following proposals:

(a) Compartmentalized trenches dug in clay of “very low” permeability so that different chemicals and wastes could be separated at the time of disposal;
(b) Covering of filled trenches with soil to a minimum depth of two feet above the waste, then having the soil resod-ded with Bermuda grass;
(c) Ten feet of fill clay on each side of the trenches to prevent drainage into them;
(d) The possible consideration of placing extremely hazardous chemicals into separate containers or compartments;
(e) A gravel road into the site and a hog-wire type fence around the landfill;
(f) The maintenance of a complete log showing the type and the amount of waste and transport information on all deliveries made to the site; and
(g) Monthly reporting to the Oklahoma State Department of Health.

7. In connection with Royal Hardage’s permit application, soil core samples had been collected at the proposed site by Standard Testing and Engineering Company of Enid, Oklahoma on August 30 and 31,1972.

8. Laboratory testing consisted of moisture and density determinations and permeability tests on remolded samples using a Soiltest Model K-620 permeameter.

9. The company reported that the natural dry density of the clay-rich shale at a depth of approximately 29 feet ranged from 129.8 lb/ft at 11.3% moisture in hole 5 to 125.8 lb/ft at 11.5% moisture in hole 6, and that the average density was 127.8 lb/ft at 11.4% moisture.

10. Remolded permeability samples were compacted to 121.1 lb/ft at 13.5% moisture in hole 4, 126.3 lb/ft at 11.4% moisture in hole 6, and 125.5 lb/ft at 12.0% moisture in hole 7.

11. The company reported that the K values of the permeability tests ranged from 5.793 X 10~8 cm/sec in hole 4 to 1.906 in 10 _8 cm/sec in hole 6 to 4.646 X 10 ~8 cm/sec in hole 7, and noted that according to Soil Testing for Engineers by T. William Lambe of Massachusetts Institute of Technology (1951), any soil with a K value of less than 10-7 cm/sec is considered “practically impermeable.”

12. Since no established test standards existed for the application, the company warranted only that the test results were based on full compliance with the specified laboratory methods and procedures.

13. On September 15, 1972, based upon Hardage’s application, Loyd F. Pummill, State Sanitary Engineer and R. Leroy Carpenter, M.D., State Commissioner of Health, Oklahoma State Department of Health granted Royal N. Hardage a permit to construct, operate and maintain an Industrial Waste Disposal facility located approximately three quarters of a mile west of Criner, Oklahoma in SWV4, SW'A, and SV2, NWV4, SWV4, Section 24, T6N, R4W, McClain County, Oklahoma under Permit No. 3544005.

14. The permit conditions were:

(a) In the event that a permeable lens or fissure was encountered during construction of a pit, a blanket of clay was to be used to develop a buffer against the lateral movement of waste material.
(b) The site was to be operated in a manner consistent with requirements of the Oklahoma State Department of Health, and disposal techniques were to be employed that would provide maximum protection to the environment, employees, and persons hauling wastes to the site.
(c) If the Oklahoma State Department of Health requested, the operator of the site would provide monitoring wells, as necessary, to monitor the possible escape of waste or dangerous derivatives from the site.
(d) When an active portion of the site was filled with waste, or when the site in its entirety was no longer capable of accepting waste for disposal, the portion of the site, or the site in its entirety, would be closed in a manner consistent with Section 4.3 of the Rules and Regulations of the Oklahoma Solid Waste Management Act.

15. On approximately October 2, 1972, shortly after receiving this operational permit, Royal Hardage opened his hazardous waste disposal site and began receiving waste.

16. On August 13, 1976, in order to comply with the Oklahoma Industrial Waste Act, House Bill 1811, Royal Hard-age proposed the following amendments to his disposal and operational plan:

(a) Establish three escrow accounts, in lieu of liability insurance, underground insurance, and performance bonds, respectively;
(b) Hire a qualified chemist or chemical engineer as site supervisor;
(c) Provide for the construction of fences and wells and the posting of signs;
(d) Formulate a plan to provide for soil farming of specific materials which are biodegradable;
(e) Construct a drying chamber for sludge and liquid wastes;
(f) Cover the main pit to exclude rainwater, to avoid seepage and spills and to eliminate odors created in wet conditions;
(g) Provide a trailer house for the site supervisor; and
(h) Provide a water tower and water system for latrine facilities and safety showers.
On August 30, 1976, the OSDH approved these amendments.

17. In September 1979, the Oklahoma State Department of Health initiated administrative procedures to revoke Hard-age’s permit based upon violations of the Oklahoma Controlled Industrial Waste Disposal Act and the Solid Waste Management Act and alleged violations of the conditions of Permit No. 3544005.

SITE HISTORY-OPERATIONS

18. Prior to the use of the Hardage site as a waste treatment, storage, and disposal facility, the property was most likely used in an agricultural fashion, as is evidenced by examining an aerial, agricultural historical photograph dated December 12, 1969.

19. The site was open for the receipt of waste from October, 1972 through November, 1980 except for a period from February through August, 1976. Until June, 1979, the Hardage site was the only permitted industrial waste landfill in the State of Oklahoma.

20. Mr. Hardage received and accepted waste at the site from at least 385 known customers. Mr. Hardage determined the manner by which these solid wastes, hazardous wastes, and hazardous substances were treated, stored, and/or disposed of at the Hardage site.

21. Beginning in 1972, Mr. Hardage maintained a ledger showing the generator, transporter, description, volume, and after 1976, the ticket number for most wastes disposed of at the site. Beginning in 1976, shipping manifests were used to record the shipment of waste to the Hardage site.

22. Certain of Mr. Hardage’s operational techniques were consistent with those practices conducted by owners and operators of other hazardous waste sites. At the Hardage site the general operations and site activities increased the ability of precipitation events to carry sediment from the source areas via surface pathways.

23. No job-related employee injuries occurred at the Hardage site during the years in which it was operative.

24. Waste materials were treated, stored, and/or disposed of in a limited number of areas that are referred to as the source areas. Based upon Mr. Hardage’s knowledge, the disposal of waste never occurred at the Hardage site outside these source areas. Contaminated liquid from the “Main Pit” was sometimes used to irrigate grass at the site, and pond surfaces were agitated to increase evaporation. Some of Hardage’s operations also resulted in removing vegetation. Generally, when vegetation has been removed, surface water runoff increases.

25. Most wastes received at the Hard-age site were treated, stored, and/or disposed of in unlined pits after mixture with soil. Generally, wastes were not separated, and different types of wastes were commingled in the same pits. During a site visit on August 27, 1979, it was noted that the pits were unlined. It was also noted in the August 27, 1989 memorandum that there was no sampling program and no testing facilities were employed.

26. Many wastes received at the Hard-age site were treated, stored, and/or disposed of within the Main Pit. The Main Pit was located on top of a ridge situated approximately at the center of the site. The depth was not uniform, due to a trench that had been dug along the west side of the pit floor at the time of its construction, and also due to the downward slope of the floor of the pit from south to north. Construction of the Main Pit included excavation of the site surficial soils and bedrock. The clay material recovered in excavating the Main Pit was used to construct a berm on the west side of the pit to compensate for the slope of the ground.

27. Both bulked and drummed wastes were disposed of in the Main Pit. Drummed wastes were sometimes permitted to roll down the bank of the Main Pit/Barrel Mound to its bottom during which the drum’s ring and lid were occasionally loosened and separated from the rest of the drum.

28. In 1972, Mr. Hardage made an effort to segregate caustic and acidic wastes within the' Main Pit. He dumped caustic waste into the south compartment of the trench and acidic waste into the north compartment in the Main Pit. This effort was later abandoned when the accumulation of rainwater caused the compartments to overflow and the contents to mix within the Main Pit. Water siphoned from the Main Pit was collected in a series of small ponds, 2 to 3 feet deep, which Hardage excavated in the drainageway located to the west of the Main Pit.

29. In December, 1974, Lawrence Ka-putska, a graduate student at Oklahoma State University reported that Royal N. Hardage had begun the practice of draining liquid waste from the Main Pit into small ponds west of the Main Pit. In March, 1978, an Oklahoma State Department of Health inspection revealed that Mr. Hardage was pumping rainwater from the Main Pit into three smaller pits east of the Main Pit (the “East Pond area”). This liquid was sometimes sprayed into the Main Pit or onto its sides in order to enhance evaporation.

30. Waste materials were mixed with soil and redeposited in a landfill or stockpile area south of the Main Pit. Asphaltic sludge from the Main Pit and other bulk wastes were deposited in layers in one of the mixing pits, alternating the waste with layers of soil. The mixing pit that received alternate layers of soil, asphaltic sludge, and other bulk wastes eventually formed a mound, which then was covered with a final layer of fresh soil. The resultant mound area came to be known as the Sludge Mound. In addition to the waste/soil mixture, drums of cyanide waste and cyanide pots were buried within the Sludge Mound. Hardened cyanide had been received at the site in pots measuring 4 to 5 feet tall and 2 to 3 feet in diameter. Layers of dirt were placed between layers of waste.

31. By September, 1979, the Sludge Mound had been covered completely with 1 to 2 feet of dirt. Later, however, Mr. Hardage repeated the process of mixing soil and dirt with wastes and liquid that had been pumped or drained from the Main Pit. By April 28, 1981, this mixed material had been placed into the Main Pit and covered with soil. The mixing occurred in areas north, west, and east of the Main Pit.

32. When the wastes and contaminated soils had filled the Sludge Mound area to approximately the height of the original ground surface, the sludge and contaminated soils were thereafter placed in alternating thin lifts. This practice resulted in elevating the Sludge Mound to a final height of 10 to 15 feet.

In 1976, a second pit was constructed north of the Main Pit (the “North Pit”). This new pit became the primary receptacle for bulk liquids and solid wastes. During this time, the Main Pit was emptied and deepened. The sludges from the Main Pit were taken to the mixing area of the Sludge Mound where they were dried. The sludges were deposited in approximately 5 inch layers within the Sludge Mound. Upon reopening the site in 1976, liquids from both the North and the Main Pits were periodically released into the West Pond area where they were mixed with soils. This mixture was then placed in the Main Pit.

33. In August or September, 1977, Mr. Hardage constructed a second dike west of the Main Pit. The main dike in the pit was then cut, and a portion of the liquids was drained into this secondary area that was approximately 40 to 50 feet wide and 150 feet long. The purpose of this activity was to provide more room in which to mix dirt with the liquids and thereby “dry up” the waste materials. Another mixing location was in the North Pit area where bulk wastes were mixed with soil in three long ponds.

34. In early 1979, Mr. Hardage began drying out the Main Pit by mixing liquids and sludges with dirt from the site. The Main Pit was emptied because he had a problem with accumulation of rainwater, which was a constant problem for Mr. Hardage. He intended to resolve the problem by constructing a roof over the Main Pit supported by telephone poles. However, the roof structure was never fully completed and the telephone poles were cut off at their base in 1980.

35. The majority of the wastes received at the Hardage site in 55-gallon drums were disposed of in its northern section, later called the Barrel Mound. The practice of placing empty, and later full, barrels of waste in the pit of the Barrel Mound probably began in the fall of 1974. When Mr. Hardage buried barrels in the Barrel Mound, he placed contaminated soil around and on top of the barrels. Drummed wastes that were disposed of in the Barrel Mound were not separated by chemical type, but they were segregated from drummed waste disposed of on the west side of the Main Pit. Some drums were buried intact, but others were ruptured or punctured at the time they were disposed of in the Barrel Mound.

36. Drums were sometimes dumped onto the Barrel Mound by trucks tilting their beds which allowed the drums to roll into the Barrel Mound. The drums dumped in this manner often remained where they landed in the Barrel Mound. Small trucks sometimes drove on top of the Barrel Mound to deposit barrels or drums. A bulldozer was sometimes used to place soil on top of the barrels. Some drums in the Barrel Mound were observed leaking.

37. After the first few years of operation, arsenic and cyanide drums were placed along the eastern side of the Barrel Mound. Bags of asbestos insulation were also disposed of in this mound. These bags were placed among barrels on the face of the Barrel Mound and covered with earth. During this period, contaminated soils used to cover the barrels were excavated from the East Pond and West Pond area.

38. Construction of the Barrel Mound, which is contiguous with the Main Pit, began in the fall of 1974. The Main Pit and Barrel Mound are approximately 800 feet by 250 feet in plan dimension. The Sludge Mound is approximately 500 feet by 200 feet. The base of the Sludge Mound generally occurs at a depth of 22 feet, the base of the Main Pit ranges from about 14 feet at the southern end up to about 24 feet at the northern part, and the depth to the base of the Barrel Mound is generally between 26 to 28 feet. The Barrel Mound was constructed by excavating in Stratum I to approximately 30 feet above the Stratum I/II contact. The Main Pit and Barrel Mound have a combined volume of approximately 117,200 cubic yards and the volume of the Sludge Mound is approximately 76,-000 cubic yards.

39. As many as four hundred black, plastic-lined metal drums were stored unopened in a stack northwest of the Barrel Mound for approximately two years. Some of the drums had corroded.

40. Certain aspects of the operational history of the Hardage site may be determined by evaluating existing photographs. This evaluation provides the following information:

(a) A continuous north-south berm existed on the western side of the Hardage site. This berm diverted surface water runoff from the west side of the berm toward the south to just below the South Pond.
(b) The road going into the Hardage site, shown on an October 4, 1975, aerial photograph, is the road to the east of the Sludge Mound, Main Pit, and Barrel Mound areas. This road could have acted as a barrier to surface runoff going east from these areas, because it generally follows the ridge line between the two drainages.
(c) A November 2, 1978 photograph shows that surface water runoff from the Barrel Mound, Main pit, and the Sludge Mound is toward the southwest. Runoff from the southwest corner of the Sludge Mound would reach the South Pond area.
(d) The November 2, 1978 photograph does not show any change in the road structures of the Main Pit, Barrel Mound, and Sludge Mound that would indicate that surface water runoff from those areas could go east.
(e) The November 2, 1978 photograph shows that surface water runoff form the East Pit area would flow southeast toward the east drainage ditch.
(f) The September 9, 1979 photograph shows that the drainage from the North Pit area goes south, traveling between the main drainage channel and the Main Pit and then is diverted around a berm across a small access road and ends up in the South Pond.
(g) The September 9, 1979 photograph shows that surface drainage from the Main Pit, Barrel Mound, and Sludge Mound is generally toward the South Pond.
(h) In comparison to the October 4, 1975, aerial photograph of the Hardage site, the November 2, 1978, aerial photograph of the Hardage site shows that the west pits were no longer present and the west pit area appeared to be graded and fairly uniform; the sludge pit had been transformed into a mound and was completely covered over; the Main Pit contained a large amount of earth material with a small area of standing liquid; the Barrel Mound was larger; there was an east pit area consisting of four pits which did not contain liquid; the north pit area had a number of small diked pits all containing liquid; an interceptor trench had been dug just north of the south pond and contained liquid; some horizontal tanks were present near the Barrel Mound; and there was a berm between the drainage and the west pit area.
(i) The November 2, 1978 photograph does not indicate that any waste material was present in the east pit area.
(j) In comparison with a November 2, 1978, aerial photograph of the Hard-age site, the 1979 aerial photograph shows that the interceptor trench was still present and it contained liquid; all the ponds in the west drainage were empty, and the west pit area appeared to be active; the Main Pit had “a lot of” liquid in it; there were drums in the Main Pit, and they extended into the Barrel Mound; the north pit area was no longer present, except for a small waste pit containing liquid; the building that had been under construction in 1978 had been completed, and there were drums around it; and the east pit area was no longer a pit area and had been revegetated.
(k) The September 2, 1979, photo of the site shows that the entire drainage ditch to the west of the Sludge Mound had been cleared of vegetation.
(l) The 1975 and 1978 photographs show that Royal Hardage built dikes, put berms around the mounds, dug pits to contain the waste, attempted to re-vegetate the west pit area and replant the two mound areas.
(m) A September 9, 1979, aerial photograph of the Hardage site shows that a berm had been constructed around the lower east farm pond in an attempt to keep runoff from entering the pond.

41. Hardage arranged with contractors to have a number of open boreholes installed at the site during its years of operation. In 1976, Standard Testing and Engineering drilled six uncased monitoring wells at the Hardage site, each of whose diameter was 6 to 10 inches. These wells, later called “HW-Series” wells, varied in depth from approximately 25 feet to 89 feet. Since these uncased boreholes did not yield very much water, each was enlarged by Fred’s Rat Hole Service sometime between 1976 and 1980 to a diameter of approximately 36 inches to 48 inches. By approximately 1980, at least five of these six uncased monitoring wells (Nos. 2 through 6) had been covered with concrete pads.

42. Two additional open boreholes were installed by Fred’s Rat Hole Service on November 12 and 13, 1979. These wells were drilled to a depth of 31 feet and had diameters of 48 inches. Four other test holes were installed by Meyer Pump Service on March 1, 1982. These wells were drilled to a depth of 30 feet. On March 20, 1982, these wells were sampled by the Oklahoma State Department of Health, but, by March 24, 1982, one of them had been damaged by the use of heavy equipment at the Hardage site. Four additional boreholes were installed at the Hardage site by Fred’s Rat Hole Service on March 26 and 29, 1982. Each of these holes were drilled at a depth of 30 feet and had a diameter of 48 inches.

43. Thereafter, additional open boreholes were either installed at the Hardage site or existing boreholes were enlarged. It is difficult to precisely distinguish between these two events from the existing documentary record. Three existing holes were either enlarged or three new boreholes were installed by Fred’s Rat Hole Service on March 31, 1982. At this time, the final depth and diameter of these boreholes were 14 feet and 90 inches, 14 feet and 84 inches, 5 feet and 38 inches, respectively. Two final holes were either installed or enlarged by Fred’s Rat Hole Service on April 6, 1982. At this time, these holes were drilled to a depth of 30 feet and a diameter of 48 inches. Consequently, in all, no less than 16 and no more than 21 boreholes were installed at the site by March, 1982.

44. As of 1979, there was no evidence that there was vertical movement of liquid downward into the ground water. There was evidence of surface seepage through the west wall of the Main Pit. In 1979, surface seepage was also observed from the excavated portion of the Main Pit’s western dike. Materials were applied to the Main Pit and grass cover was provided over the site to decrease the rate of seepage and erosion. By August 25, 1980, there was evidence of erosion along the Main Pit dike and the west pits, while the southern half of the Main Pit was dried out and covered. By 1983-1984, some erosion of the Sludge and Barrel Mounds was evident and stains were observed on top of the Main Pit.

45. Mr. Hardage took a number of measures during his operations to prevent contaminated stormwater from leaving the site. These measures included the construction of trenches, ponds, and a drying shed to dry waste prior to placement, as well as installation of wells. However, these measures were not completely effective at localizing the waste constituents to the site. On at least one occasion following a rainstorm, surface water runoff was observed leaving the site from the mounds and flowing toward the southwest toward North Criner Creek.

46. On July 30, 1980, Diana Dutton, Director, Enforcement Division, United States Environmental Protection Agency, sent a letter to Royal N. Hardage requesting him to:

(a) Cease accepting any and all wastes;
(b) Cease removing liquids from the Main Pit and mixing them with soil in the small temporary pits;
(c) Cease any and all earthmoving or remedial actions at the site, except for containment of leachate, until approval had been received for such actions from the EPA;
(d) Erect a fence around the disposal site to secure it on all sides (specifically the north side);
(e) Contain all leachate from the mounds, pits, and dikes on-site;
(f) Provide the EPA with a written plan for determining the extent of groundwater contamination, said plan to include the drilling of soil borings and monitoring wells at different points to locate the depth and extent of groundwater contamination and to determine the direction and rate of flow of the ground water. In addition, provide the EPA with a timetable for implementation of the plan once it is approved by the EPA;
(g) Provide the EPA with a map showing the location, nature, and quantities of all wastes, and other chemicals disposed of on-site;
(h) Provide the EPA with information identifying the extent of soil contamination on the site. If this information is not immediately obtainable, provide the EPA with a plan, timetable and procedure for obtaining the information;
(i) Provide the EPA with a plan for the cleanup of the site, i.e., the containment and proper disposal of wastes including those contained in the Barrel and Sludge Mounds;
(j) Provide the EPA with a plan for final disposal of on-site contaminated soils, and in addition, a timetable for implementation of the plan once it is approved by the EPA;
(k) Provide the EPA with a plan for determining the extent of the off-site contamination and a timetable for implementing the plan; and
(il) Provide the EPA with a plan for cleaning up off-site contamination, if any, and a timetable for implementation of the plan once it is approved by the EPA. [HCA008 2089-2090.]

47.The Hardage site closed for receipt of hazardous and industrial waste on November 18,1980, prior to the November 19, 1980 effective date of regulations published pursuant to the Resource Conversation and Recovery Act, and has remained closed to the present. From 1980 through early 1981, Mr. Hardage conducted a number of closure activities including pumping liquid from the Main Pit into shallow pits, mixing the liquid with soil, then transporting the liquid back into the Main Pit; drilling two new interceptor wells to the southwest of the existing monitoring wells; and emptying waste from the sludge drying building. Additional site closure activities included covering the Main Pit and the Barrel Mound with approximately 3 feet of site soil; covering one of the two mixing areas with soil and grass about 4 to 6 inches deep; scraping the North Pit and South Pond and depositing the material from this area on the Sludge Mound; and covering the Sludge Mound with approximately three feet of soil.

48. Approximately 20 million gallons of hazardous substances were transported to, treated at, stored at and/or disposed of at the Hardage site.

49. Various departments, agencies and instrumentalities of the United States arranged for disposal or treatment by contract agreement or otherwise of approximately 920,000 gallons of hazardous substances at the Hardage site.

50. The remaining Defendants arranged for disposal or treatment by contract agreement or otherwise of approximately 8.2 million gallons of hazardous substances at the Hardage site.

51. Various “orphans,” or parties potentially financially unable to pay their reasonable allocation of response or remedial costs associated with the Hardage site, arranged for disposal or treatment by contract agreement or otherwise of approximately 9.0 million gallons of hazardous substances at the Hardage site.

52. The Hardage Steering Committee Defendants arranged for disposal or treatment by contract agreement or otherwise of approximately 6.9 million gallons of hazardous substances at the Hardage site.

53. Because of the generation of hazardous substances by various agencies or instrumentalities of the United States, the United States is a person liable for relief in connection with the Hardage site pursuant to CERCLA § 106 42 U.S.C. § 9606, and 107, 42 U.S.C. § 9607. The United States reserves its rights to argue that the activities of the United States Environmental Protection Agency should not be considered among the equitable factors in any contribution claim under CERCLA § 113 and that such activities do not give rise to any liability, and further that the liability arising from the generation of hazardous substances may be satisfied other than by contribution to the HSC.

54. The United States and the Hardage Steering Committee Defendants do not agree about the significance of the “orphan share.” Both the United States and the Hardage Steering Committee expressly reserve their rights to assert the liability of any and all persons for the orphan share or any part thereof, including but not limited to, the liability of parent for subsidiary, of master for servant or of transporter for generator.

55. The parties stipulate that the observations and sampling results listed in stipulation 57 have been reported in one or more documents. The parties reserve the right to contest at trial the accuracy of the observations and sampling results.

56. The parties raise no issues pertaining to the admissibility of reports of investigations and studies except that the parties reserve the right to contest at trial the use of and weight to be accorded particular data, observations and conclusions contained in documents listed under stipulation 57.

57. Relevant regulatory inspections and visits and site investigations and studies (including sampling and analysis) conducted by state and federal regulatory agencies, or their agents, and by regulated individuals or entities, or their agents and by the Hardage Steering Committee and its agents, include, but are not limited to:

LITIGATION HISTORY

58. On or about September 8, 1980, the Government filed a Complaint against Royal N. Hardage, the owner and operator of the Hardage site, under § 7003 of RCRA, 42 U.S.C. § 6973.

59. Following the passage of CERCLA, this complaint was amended and supplemented in June 1982, to include claims for injunctive relief under § 106 of CERCLA, 42 U.S.C. § 9606, and for cost recovery under § 107 of CERCLA, 42 U.S.C. § 9607.

60. The Court held Mr. Hardage liable on December 13, 1982.

61. The court bifurcated the liability from the remedy aspects of the case, and after a hearing on liability, the court ruled on December 31, 1982, that Mr. Hardage was a liable party.

62. The Honorable Lee R. West entered an Order on July 18, 1983, directing Royal N. Hardage to allow the U.S. Environmental Protection Agency to enter and inspect the Hardage site.

63. The United States received a judgment against Mr. Hardage in the amount of $211,795.05; on August 25, 1983, Royal N. Hardage commenced bankruptcy proceedings in the United States Bankruptcy Court for the Western District of Oklahoma and all claims against Mr. Hardage by the United States were subsequently discharged.

64. EPA notified the Defendants that they were potentially responsible parties (“PRPs”) for the Hardage site in December, 1984.

65. On January 24, 1985, the EPA held a public briefing in Dallas, Texas calling for organization of the PRPs, and at that time, EPA was notified that the Hardage Steering Committee (“HSC”) had been established by the PRPs.

66. On July 18, 1985, the case styled United States of America v. Hardage, Case No. CIV-80-1301W was administratively closed.

67. On September 6, 1985, EPA advised the HSC of its intent to divide the study and remediation of the site into two operable units: the first being source control and the second being management of migration.

68. In February 1986, EPA affirmed its decision to separate the issue of source control and migration for purposes of the study and remediation of the site.

END AN GERMENT/RISK

69. There may be an “imminent and substantial endangerment to the public health or welfare or the environment because of an actual or threatened release of a hazardous substance from the Hardage site”, within the meaning of Section 106(a) of CERCLA, that is legally sufficient to require a remedy for the Hardage site.

70. Releases of hazardous substances have occurred at the Hardage site.

71. An assessment of risks to human health and the environment at a Superfund site may include the following: (a) identification of hazardous substances on-site; (b) evaluation of the toxicity of those substances; (c) estimation of human exposure; (d) estimation of human intake or dose; and (e) risk characterization.

72. An assessment of the relative risks associated with alternative remedies for a Superfund site may include an evaluation of the risk to workers and other persons involved in implementing the remedy.

73. An assessment of the relative risks associated with alternative remedies may include an evaluation of the risks to off-site residents and off-site ecologic resources.

74. An assessment of the relative risks associated with alternative remedies for a Superfund site may consider local meteorological data to estimate off-site emission concentrations of hazardous substances.

75. Both quantitative and qualitative differences in short-term (implementation-related) and long-term (post-implementation) health and environmental risks may be considered when comparing the relative risks of two alternative remedies for a Superfund site.

76. An assessment of the relative risks associated with alternative remedies for a Superfund site may include an estimate of the concentrations of contaminants and dusts and vapors that may be released into the ambient air surrounding the site during implementation of a remedy.

77. An assessment of the relative risks associated with alternative remedies for a Superfund site may include an estimate of the concentrations of hazardous substances that may, as a result of releases of substances during implementation of a remedy, accumulate in foods grown or produced off-site.

78. A comparative evaluation of the risks presented by the remedies proposed by EPA and the HSC for the Hardage site using methods and models employed by EPA would, inter alia, evaluate the same hazardous substances, the same exposure pathways, and employ the same quantitative methods of assessing off-site human exposures and health risks.

79. Implementation of a remedy at a Superfund site may pose health and occupational risks to workers and other persons involved in the response work.

80. The waste material in the Hardage site source areas contains heterogeneously mixed organic and inorganic compounds.

81. The total number of drums of waste in the barrel mound and the main pit at the Hardage site is estimated at 18,000 drums.

82. Substantial erosion of the Hardage site has occurred in the past, requiring interim remedial measures.

83. Erosion of the Hardage site enhances the likelihood of hazardous substances migrating off-site, as they are exposed to surface water run-off and wind.

84. Hazardous substances from the Hardage site may migrate off-site through several means, including groundwater, surface water run-off, and wind-blown vapors and dust.

85. Humans may be exposed to hazardous substances released at or from the Hardage site through several pathways, including dermal absorption, inhalation of vapors, inhalation of contaminated particles, ingestion of contaminated groundwater or surface water, and ingestion of contaminated fish, animals, cows’ milk, or otherwise through the food chain.

86. Many of the hazardous substances detected at the Hardage site, and in the vicinity of the site, are known or suspected human carcinogens.

87. Approximately 114 persons in 30 dwellings reside within three miles of the Hardage site.

88. Substances disposed of at the Hard-age site include ignitables, corrosives, toxic materials, and possibly reactive materials.

89. An assessment of the relative risks to workers and other persons involved in constructing alternative remedies for a Superfund site may consider the nature of specific response tasks and the number of man-hours required to complete each task.

90. Workers at a Superfund site who use protective clothing and equipment may be exposed to hazardous substances if seals between the face and the respirator are loose, if hazardous substances penetrate the protective clothing, if the protective clothing is not sealed properly, if the protective clothing tears from contact with sharp objects, or if the safety gear is improperly used or removed during contact with hazardous substances.

REMEDIAL ACTION-ARARS

91. The applicable or relevant and appropriate requirements pertinent to surface water quality criteria are:

(a) N. Criner Creek”:
[Except where noted below the following Oklahoma Water Quality Standards apply]. Dissolved oxygen concentration, § 7.3[a]; oil and grease, § 7.3[d]; toxicity to aquatic organisms, § 7.3[i]; agriculture, § 7.4; nutrients, § 7.10[b]; solids, § 7.10[c]; and taste (organoleptic compounds) and odor § 7.10[d].
** The following Oklahoma Water Quality Standards apply when the flow of North Criner Creek immediately upstream of the discharge point is one (1) cfs or greater; Fish and Wildlife Propagation/Secondary Warm Water Fishing (7.3), Agriculture (7.4), Industrial and Municipal Process and Cooling Water (7.6), Secondary Body Contact Recreation (7.8), and Aesthetics (7.10).
(b) Criner Creek:
Public and Private Water Supply, § 7.1; Fish and Wildlife Propagation/Primary, Warm Water Fisheries, § 7.3; Agriculture, § 7.4; Industrial and Municipal Process and Cooling Water, § 7.6; Primary Body Contact Recreation, § 7.7; and Aesthetics, § 7.10.

92. The remedial alternatives, as described in the United States’ Remedy Report filed October 13, 1989, any Record of Decision issued by EPA concerning the new proposed remedy, and the Hardage Steering Committee Defendants’ Remedy Report filed October 13, 1989 in this action, do not violate the Resource Conservation and Recovery Act, 42 U.S.C. Sections 6901 et seq., restrictions on the land disposal of hazardous wastes.

GEOLOGY/HYDROGEOLOGY

93. The Hardage site is immediately underlain entirely by Permian-aged sedimentary rocks in the Central Redbed Plains of Oklahoma; younger soils overlie the Permian rocks over much of the site, and alluvial sedimentary deposits are found along North Criner Creek and in the southwest corner of the site.

94. Quaternary alluvium deposits are exposed at the south and southwest areas of the site adjacent to North Criner Creek, and attain a measured thickness of 50 to 60 feet at existing well locations.

95. The geological bedrock formations encountered at the Hardage site consist of sandstones, siltstones, and mudstones and combinations thereof.

96. Stratum I, the uppermost stratum group, is composed mainly of sandstone and siltstone with some interbedded mud-stone. Because the beds are relatively flat lying, Stratum I thins as surface elevation decreases and is completely absent from some boring samples in southern portions of the site.

97. Stratum I occurs at the site generally above an elevation of 1,090 feet (MSL); the thickness of Stratum I at the site ranges from 0 to about 40 feet.

98. Outcrops at the Hardage site to the west and southwest of the sludge drying building are Stratum I and consist of several cross-bedded, lenticular shaped sandstone bodies in horizontal and vertical contact with siltstone and very silty mudstone beds.

99. Stratum II is composed predominantly of mudstone and silty mudstone with occasional interbedded sandstone and siltstone layers.

100. Stratum II occurs at the site generally between the elevations of 1,090 feet (MSL) and 1,074 feet (MSL); the thickness of Stratum II ranges from about 16 to 29 feet.

101. Stratum III is composed predominantly of sandstone, with varying amounts of interbedded siltstone and mudstone.

102. Stratum III occurs at the site generally between the elevations of 1,074 feet (MSL) and 1,040 feet (MSL); Stratum III ranges in thickness from about 35 to 42 feet.

103. Stratum IV is composed predominantly of mudstone and silty mudstone, with silty mudstone and siltstone layers present in the upper 20 feet.

104. Stratum IV occurs at the site generally between the elevations of 1,040 feet (MSL) and 960 feet (MSL); it has a thickness of between 76 and 84 feet.

105. Stratum V underlies Stratum IV between the elevations of about 960 feet (MSL) to 860 feet (MSL) and consists predominantly of interbedded mudstone and siltstone with lesser amounts of sandstone.

106. Stratum VI is found below an approximate elevation of 860 feet (MSL) and contains a relatively continuous zone of sandstone interbedded with lesser amounts of siltstone within the upper 50 feet.

107. Stratum VI contains saline ground water with concentrations of total dissolved solids in the 15,000 to 20,000 mg/1 range.

108. Most surface runoff originating from the barrel mound, main pit, and sludge mound at the Hardage site flows to the southwest and enters the west farm pond, south pond, or the bar ditch southwest of the south pond, or North Criner Creek. A smaller portion flows eastward, discharging into the east farm ponds.

109. The surface runoff from the central portion of the Hardage site area is split into westerly and easterly flow components by the north-southridge line that runs through the center of the original site. Surface water runoff to the east flows toward the three east farm ponds while surface water runoff west of the ridge eventually flows into or around the south pond area in the southwest corner of the site toward North Criner Creek.

110. The ultimate destination of surface runoff and seepage water at the Hardage site is North Criner Creek.

111. Some of the surface runoff and seepage water infiltrates the sandstone near the surface in the southern portion of the site and seeps to the bar ditch or into the alluvium southwest of the site.

112. The alluvium within the southwest portion of the site consists of unconsolidated, laterally discontinuous, sand beds, and is underlain predominantly by stratum IV mudstone.

113. The horizontal hydraulic transmis-sivity of the alluvium ranges from approximately 10 gpd/ft to 4,050 gpd/ft.

GOVERNMENT RESPONSE COSTS

114. The Government’s DOJ and EPA cost summaries submitted in support of the motion for partial summary judgment on response cost issue identify invoices which are described on their faces as invoices for Hardage site work. The Government has paid these invoices. The summaries also identify additional invoices which are not described on their faces as specific to the Hardage site. The Government also has paid these invoices.

115. The Government has paid various of its employees the amounts shown on the summaries submitted in support of the motion for partial summary judgment on response cost issue for hours which employees charged on their time sheets to the Hardage case.

116. The Defendants do not dispute that the Government has paid various of its employees the amounts shown on the EPA cost summary attached to the declaration of Nellie Boone and the DOJ cost summary attached to the declaration of Patrick A. McGeehin submitted in support of the motion for partial summary judgment on response cost issues.

117. The indirect cost rates computed by EPA for EPA Region VI were $66 per hour in fiscal year 1983, $60 per hour in fiscal year 1984, $54 per hour in fiscal year 1985, $53 per hour in fiscal year 19S6, $52 per hour in fiscal year 1987. The provisional rates for fiscal years 1988 and 1989 are: $52 per hour in fiscal year 1988, and $52 per hour in fiscal year 1989.

118. The number of site-specific hours billed to the Hardage site by EPA Region VI personnel in program divisions in the years 1983 through December 31, 1989 were: 1983, 587; 1984, 409; 1985, 1,105.5; 1986, 1,727.5; 1987, 1,817; 1988, 2468; 1989, 700.

HSC’s COUNTERCLAIM FOR COST RECOVERY

119. The HSC’s costs for which it seeks recovery have been summarized and recorded under an accrual basis of accounting.

120. The HSC installed and has maintained a chain link fence and warning signs around the Hardage site in accordance with the Stipulation Regarding Installation and Maintenance of a Fence at the Hardage site between the United States and the HSC Defendants filed with the United States District Court for the Western District of Oklahoma on April 29, 1987 (“Fence Stipulation”).

121. Installation of a fence to limit access to and provide security at a Superfund site constitutes a response action under CERCLA.

122. By letter dated January 28, 1988, the completed work pursuant to the fence stipulation has been approved by the United States. [Letter from Mary Ellen McClary to Steven M. Morgan, January 28, 1988].

123. The work performed by HSC Defendants pursuant to the Fence Stipulation is consistent with the National Contingency Plan.

124. The HSC constructed a water line to provide an alternative water supply to residents living near the Hardage site and has provided an alternative water supply to them.

125. Providing an alternative water supply constitutes a response action under CERCLA.

126. The HSC performed certain interim repairs of the soil cover over the Barrel Mound, pursuant to the stipulation Regarding Interim Repair and Maintenance of Hardage Site Source Area, which was filed with the Court on February 2, 1988 (“Repair Stipulation”).

127. The HSC performed work at the site in accordance with the Work Plan attached to the Repair Stipulation.

128. The HSC’s work pursuant to the Repair Stipulation constitutes a response action under CERCLA.

129. The HSC’S work pursuant to the Repair Stipulation is consistent with the National Contingency Plan.

130. The HSC performed a Remedial Investigation/Feasibility Study (“RI/FS”) for the second operable unit at the Hardage site to determine the existence and extent of contamination at the site, to determine the existence and extent of any threat to public health or welfare or the environment posed by the migration of any contamination at the site, and to determine and evaluate alternatives for any appropriate remedial response actions necessary to address the second operable unit at the Hardage site.

131. The conduct of a remedial investigation/feasibility study is a response action under CERCLA.

132. The United States and the HSC Defendants entered into a Partial Consent Decree governing the performance of the Remedial Investigation/Feasibility Study for the second operable unit, which was entered by the Court.

133. The HSC has conducted a number of site investigations, studies, tests, and data-gathering efforts at the Hardage site.

Filed Nov. 22, 1989

COME NOW the plaintiff and the defendants, pursuant to the court’s pretrial scheduling order of January 20, 1989, as modified on July 27, 1989, and file the following stipulation:

The United States and the Hardage Steering Committee Defendants stipulate that neither will offer for admission into evidence, nor discuss or refer to in Phase I of the trial, information concerning the nature of the wastes sent to the Hardage Site by either of them for any reason other than as relevant to risk or choice of remedy. The United States and the Hardage Steering Committee Defendants agree that neither the nature of the wastes, nor the waste handling or generation practices of either of them are factors relevant to determining the appropriate contribution share of the United States because of the generation of hazardous materials by the federal facilities. “Nature of the wastes” for purposes of this stipulation includes, without being limited to, the following matters: chemical composition, toxicity, mobility, flammability, reactivity, or any other physical or chemical characteristic of the substance. Nothing in this stipulation shall prejudice the Hardage Steering Committee Defendants’ right to offer evidence or make any arguments it deems appropriate concerning any other aspect of the United States’ conduct, including but not limited to, EPA’s conduct, to determine the share of responsibility, if any, that ought to be assigned to the United States for any and all costs and liabilities incurred in connection with the Hardage Site.

EXHIBIT D

STIPULATION REGARDING ANALYTICAL DATA: SAMPLES ON WHICH THE PARTIES AGREE

Filed Nov. 17, 1989

The Plaintiff in this action, the United States of America , on behalf of the administrator of the United States Environmental Protection Agency (“EPA”), and the Defendants stipulate to the following:

1. There have been approximately 1,480 samples taken by the parties from the Hardage site and analyzed by various laboratories. A substantial amount of the data associated with these samples has been reviewed and validated. Both sides have designated experts who have conducted a quality assurance/quality control (“QA/QC”) review of the date generated from samples taken at the Hardage site.

2. Samples taken by the Oklahoma State Department of Health are not covered by or included in this Stipulation.

3. The Plaintiff and Defendants have developed a “universe list” containing all of the samples obtained from the site sampling activities of the parties. The universe list is broken down into five categories: First Operable Unit Organic Data (“Attachment A”), First Operable Unit Inorganic Data (“Attachment B”), First Operable Unit Geochemistry Data (“Attachment C”), Second Operable Unit Data (“Attachment D”) and First Operable Unit Field Data (“Attachment E”).

4. The results of the QA/QC review of the laboratory performance in analyzing the samples contained in the universe list are accurately reported in Attachments “A”, “B”, “C” and “D”, respectively. The results of a QA/QC review of the field procedures and associated methods in collecting, handling and shipping the samples contained on the universe list are reported in Attachment “E” for the First Operable Unit Data and in Attachment “D” for the Second Operable Unit Data. These results are classified by the experts as either quantitative (“QN”), qualitative (“QL”) or not usable (“NU”).

5. The parties agree that no evidentiary objections pertaining to proper foundation will be made with respect to the samples listed in Attachments “A”, “B”, “C”, “D” and “E” and that the issues associated with “chain of custody” will not be contested at trial with respect to the samples identified in Attachments “A”, “B”, “C”, “D” and “E”.

6. As used in Attachments “A”, “B” and “C” and the Laboratory Quality Section of “D” of this Stipulation, “quantitative” means the reported results accurately reflect the absence or presence and concentration of the specific chemical compounds analyzed for in the sample as received at the laboratory.

As used in Attachments “A”, “B” and “C” and the Laboratory Quality Section of “D” of this Stipulation, “qualitative” means, except as stated below, that the reported positive analytical results reflect the presence of the specific chemical compounds analyzed for in the sample as received at the laboratory; however, the concentration of the specific chemical compounds cannot accurately be determined. Also, specific chemical compounds reported as absent may actually have been present in the sample as collected. Additional professional judgment is required of the user of the reported analytical results in assessing whether a common laboratory contaminant reported at a concentration of less than 10 times the detection limit may actually be present in the matrix at the time and location from which the sample was collected.

7. As used in Attachment “E” and in the Field Quality Section of Attachment “D” of this Stipulation, “quantitative” means that the documentation, well construction (where applicable) and field procedures followed in collecting and shipping to the laboratory a sample from a particular location and time were adequate for the sample as received at the laboratory to accurately reflect the absence or presence and concentration of the specific compounds in the matrix at the time and location from which the sample was collected.

As used in Attachment “E” and the Field Quality Section of Attachment “D” of this Stipulation, “qualitative” means that the documentation, well construction (where applicable) and field procedures followed in collecting, handling and shipping to the laboratory a sample from a particular location and time were adequate for the sample as received at the laboratory to reflect the presence of specific compounds in the matrix at the time and location from which the sample was collected; however, the concentration of the specific compounds cannot accurately be determined. Also, specific chemical compounds reported as absent may actually be present. Additional professional judgment is required of the user of the reported analytical results in assessing whether a field contaminant(s) may actually be present in the matrix at the time the sample was received at the laboratory.

8. With respect to sample results which are identified in Attachments “A” through “E” as “qualitative”, the parties reserve the right to assert that the actual concentration of a compound reported as present in the matrix from which the sample was taken is equal to, greater than, or less than the result reported for that compound.

9. As used above, and in Attachments “A”, “B”, “C”, “D” and “E” of this Stipulation, “not usable” means that the field documents and/or field procedures and/or the laboratory analysis are not reliable for technical or analytical purposes.

10. The parties agree that this Stipulation is also offered for the purpose of satisfying Task 1 of the Second Operable Unit Management of Migration Remedial Investigation/Feasibility Study Work Plan, dated May 8, 1987, pursuant to the Partial Consent Decree (Section XV, paragraph 2, Milestone B): Performance of a Remedial Investigation/Feasibility Study entered February 20, 1989 by Order Nunc Pro Tunc.

11. The Plaintiff and Defendants reserve the right to supplement the Attachments to this Stipulation with additional data which have been reviewed and agreed upon with respect to the classifications.

12. The HSC Defendants’ experts have reviewed additional data that EPA has chose not to have its experts review. This data is identified in documents called, Inorganic Analyses 9/5/89 Review/Validation, “HSC Opinion Only List” and Organic Analysis, 10/29/89, Data Review/Validation, “HSC Opinions Only”. The EPA has agreed not to render opinions by and through its witnesses about the quality or reliability of data on these lists. These lists are attached to this Stipulation as Attachments “F” and “G”.

STIPULATION REGARDING ANALYTICAL DATA: SAMPLES ON WHICH THE PARTIES DISAGREE

Filed Nov. 17, 1989

The Plaintiff in this action, the United States of America, on behalf of the administrator of the United States Environmental Protection Agency (“EPA”), and the Defendants stipulate to the following:

1. There have been approximately 1,480 samples taken by the parties from the Hardage site and analyzed by various laboratories. A substantial amount of the data associated with these samples has been reviewed and validated. Both sides have designated experts who have conducted a quality assurance/quality control (“QA/QC”) review of the data generated from samples taken at the Hardage site. Both sides have also conducted independent reviews of the field procedures and/or methods used to take the samples as well as the construction of the wells from which the samples were taken.

2. The parties have entered into a separate stipulation, STIPULATION REGARDING ANALYTICAL DATA: SAMPLES ON WHICH THE PARTIES AGREE, setting forth the samples taken from the Hardage site on which they agree as to the laboratory and/or field quality of the samples.

3. The purpose of this Stipulation is to identify the samples taken from the Hard-age site on which the parties disagree as to the reliability and usability of the samples and for which trial testimony may be offered. Attachment “A” sets forth the samples taken from the Hardage site on which the parties disagree as to the reliability and usability of the laboratory analysis. Attachment “B” sets forth the samples taken from the Hardage site on which the parties disagree as to the reliability and usability of the field procedures and/or methods, including but not limited to, field sampling, well construction, and other field data gathering issues. Attachment “B” includes both First Operable Unit Samples and Second Operable Unit Samples.

4. The parties may raise any issues with respect to the samples listed in Attachments “A” and “B” of this Stipulation, except for issues relating to “chain of custody”.

5. With respect to samples listed in Attachment “B” of this Stipulation, the parties intend to enter into negotiations to reach agreement on the quality of the field procedures and/or methods used to take the samples and the construction of the wells from which the samples were taken. If such negotiations are successful, the parties anticipate including these samples on Attachment “D” or “E” to the Stipulation Regarding Analytical Data: Samples On Which The Parties Agree.

      . Comprehensive Environmental Response, Compensation, and Liability Act of 1980, 42 U.S.C. §§ 9601-75 (1982 & Supp. V 1987), as amended by the Superfund Amendments and Reauthorization Act of 1986, Pub.L. No. 99-499, 100 Stat. 1613 (1986) [hereinafter "CERCLA" and "SARA”].
     
      
      . The trial defendants included the defendants named in the United States’ Amended Complaint. The majority of the defendants organized themselves as the Hardage Steering Committee ("HSC”) defendants. Section II of this Order contains a list of the HSC defendants.
      Other defendants for trial included the Consent Decree defendants. On the eve of trial, the United States filed the Consent Decree for the Implementation of a Partial Remedial Action: Source Excavation and Soil Vapor Extraction, United States v. Hardage, No. CIV-86-1401-P (W.D.Okla. Nov. 21, 1989) (filing No. 2218). Under the provisions of the Consent Decree certain settling defendants agreed to pay for and to perform components of the United States’ preferred remedy at the Hardage Site. Section VII of this Order describes and identifies the Consent Decree defendants. These defendants supported the United States’ recommended remedy.
     
      
      . Reporter’s Transcript of Proceedings at 95 11.-6-7 (Nov. 24, 1989). The government attorney’s line during opening statements was reminiscent of the late British Prime Minister Neville Chamberlain’s famous remark. Upon his return to London from Munich on September 30, 1938, Chamberlain proclaimed a peace pact with Hitler. Chamberlain told a throng of admirers: “I believe it is peace for our time.” J. Bartlett, Bartlett’s Familiar Quotations 727 (15th ed. 1980) (footnotes omitted).
     
      
      . See, e.g., Order at 11 (Jan. 20, 1989) (filing No. 1601) [hereinafter Jan. 20, 1989, Scheduling Order], attached hereto as Exhibit A.
     
      
      . See Order Allocating Twenty (20) Days for Remedy Trial (Nov. 6, 1989) (filing No. 2086).
     
      
      . See Jan. 20, 1989, Scheduling Order at 3-6.
     
      
      . Id. at 3.
     
      
      . Review of the witnesses’ direct examination was facilitated by the affidavit procedure described above. The Court carefully considered the cross-examination of the witnesses by means of a daily transcript service.
     
      
      . Section IX of this Order discusses the Consent Decree.
     
      
      . Section X of this Order details the United States’ response cost claim.

      . Many of the original 37 defendants organized and formed the HSC defendants. At the direction of this Court in the Case Management Order issued on March 26, 1987, all defendants were represented administratively by liaison counsel. Case Management Order (Mar. 26, 1987) (filing No. 189).
     
      
      . Section IX of this Order discusses the Consent Decree in detail.
     
      
      . Because portions of these stipulations will be helpful to an understanding of this Opinion, the above stipulations, absent the supporting data, are attached to this Order as Exhibits B, C, D, and E. The complete stipulations and supporting data accompany the original filings, which remain in the custody of the Clerk of the United States District Court for the Western District of Oklahoma.

      . The liability trial (Phase II) of this matter was conducted from April 23-25, 1990.
     
      
      . The Superfund, formerly known as the Hazardous Substance Response Trust Fund established by section 221, 42 U.S.C. § 9631, continued as the "Hazardous Substances Superfund" under section 517 of SARA, 100 Stat. 1613, 1772, which added section 9507 to the Internal Revenue Code of 1986.
     
      
      . The United States requested amendment of the Court’s September 9, 1988, order to allow certification of the record review question for interlocutory appeal pursuant to 28 U.S.C. § 1292(b). This Court initially allowed an interlocutory appeal on November 23, 1988, based upon trial estimates of from 6 to 10 months. Order Allowing Interlocutory Appeal (Nov. 23, 1988) (filing No. 1559). However, upon reconsideration, the Court withdrew its interlocutory appeal certification when trial estimates agreed upon by the parties reflected 52 days or less for trial.

      . Order of Reference to Special Master at 9 (Feb. 25, 1987) (filing No. 166).
     
      
      . Some of the descriptions in this category do not do justice to the witnesses' qualifications. Many witnesses who testified had expertise in several fields. This summary is for overview purposes only.
     
      
      . See, e.g., XII at 2344.
     
      
      . IX at 1730-49.
     
      
      . In reaching this ruling, the Court realizes there are several remedial elements common to both the government’s proposed remedy and the defendants’ proposed remedy.
     
      
      . The HSC filed a second brief opposing approval of the Consent Decree on November 19, 1989. The Vapor Extraction Group (defined in Section F, paragraphs six and seven of this Section) supported approval of the Consent Decree on December 6, 1989. The United States replied to the HSC's Opposition Briefs on December 8, 1989.
     
      
      . Factors considered in measuring settlement fairness and reasonableness include: the strength of the plaintiff’s case; the good faith efforts of the negotiators; the complexity, length, expense, and risk of litigation; the amount of opposition to the settlement; the opinions of competent counsel; and the stage of the proceeding. See In re Acushnet River & New Bedford Harbor: Proceedings re Alleged PCB Pollution, 712 F.Supp. 1019 (D.Mass.1989); Exxon, 697 F.Supp. at 692; Hooker Chems. & Plastics, 540 F.Supp. at 1072.
     
      
      . Because certain United States’ trial cost exhibits overlapped with, costs awarded by the Court in its Order Granting United States’ Motion for Partial Summary Judgment on Response Cost Issues, on May 31, 1990, the Court directed the United States to file a supplemental report summarizing the specific costs requested at trial. Order Directing Supplemental Filing (May 31, 1990) (filing No. 2895). As directed, the United States filed its response cost supplement on June 11, 1989. United States’ Supplemental Report on Claim for Response Costs (June 11, 1990) (filing No. 2932). With this Court’s permission, the United States filed revised prejudgment interest calculations on July 3, 1990. United States’ Supplemental Report on Revised Prejudgment Interest Calculation on Response Costs (July 3, 1990) (filing No. 3150), and on July 25, 1990. United States’ Second Supplemental Report on Revised Prejudgment Interest Calculation on Response Costs (July 25, 1990) (filing No. 3325).
     
      
      . On November 22, 1989, this Court dismissed the HSC’s counterclaim for indemnity and portions of the HSC’s counterclaim for contribution. Order Granting Government’s Motion to Dismiss Third, and Fourth Counterclaims for Contribution and Indemnity (Nov. 22, 1989) (filing No. 2224). That same day, the Court denied the United States' motion to dismiss the HSC’s recoupment counterclaim. Order Denying Government’s Motion to Dismiss Fifth Counterclaim for Recoupment (Nov. 22, 1989) (filing No. 2223). Therefore, only the HSC’s recoupment counterclaim and the remaining portion of the contribution counterclaim proceeded to trial.
     
      
      . The Court expresses no opinion at this time, one way or the other, as to whether this Order precludes recovery of the HSC response costs from private parties pursuant to 42 U.S.C. § 9607(a)(4)(B).
     
      
      . This time estimate should be the estimated time it would take for the direct examination of each witness in the absence of the affidavit procedure set forth in paragraphs E and F below.
     
      
      . If any unnoticed witnesses or exhibits are identified on this list, counsel shall file an affidavit setting forth: (a) the reasons why the witness and/or exhibit was not previously noticed in accordance with the Scheduling Order; (b) the reasons why the evidence should be permitted at trial; and (c) the reasons why preclusionary and/or monetary sanctions should not be imposed.
     
      
      . Any third-party defendants who do not desire to file dispositive motions prior to the November 27, 1989 remedy trial will be given an opportunity to conduct discovery and file disposi-tive motions after the remedy trial.
     
      
      . See U.S. Memorandum in Response to Motion to Reconsider at 2, attached to U.S. Application to file Memorandum in Response, filed December 12, 1988. The government on January 9, 1989, however, attached certain caveats to the 52 day trial "agreement” it reached with defendants. These caveats, however, were not disclosed to the Court by counsel for any party when the parties estimated in February, 1988 that the entire remedy trial would take 30 trial days, nor were these caveats disclosed to the Court of Appeals in connection with the 52 day trial estimate.
     
      
      . For example, both parties estimate that approximately two-thirds of their respective cases will be taken up by experts.
