Re: Malvern TCE Superfund Site Opportunity to Participate in De Minimis Settlement

Dear Sir or Madam:

This letter notifies you that the United States Environmental Protection Agency ("EPA") is now offering certain parties the opportunity to enter into a proposed second round de minimis settlement pursuant to Section 122(g) of CERCLA, 42 U.S.C. § 9622(g) and that you may qualify for this de minimis settlement in connection with the Site. A list of parties eligible to participate in this settlement is enclosed as Attachment "A."

EPA previously sent you (or your corporate predecessor) a Notice Letter with respect to the Site. This correspondence identified you as a potentially responsible party ("PRP") for the Site.

As explained in that previous letter, EPA has conducted and overseen activities at the Site in response to the release and/or threat of release of hazardous substances, pollutants and/or contaminants into the environment. In May 1999, EPA and 169 de minimis parties entered into an Administrative Order on Consent, which became effective September 28, 1999. EPA has recently learned that you intended to join that first round de minimis settlement for this Site; however, EPA's records do not reflect that this occurred. In light of this situation, EPA is providing a new document for you to sign, with most of the same terms as the prior document. However, the payment amount has been revised and updated to reflect increased costs at the Site, and the premium formulation and the reservation of rights by the United States has been revised to take into account EPA's current information regarding Site conditions. For our records, we are designating this as a second round de minimis settlement.

1. Site Background

CERCLA, more commonly known as Superfund, has several key objectives including setting priorities for cleanup of the worst hazardous sites in the country, and, determining the parties potentially responsible for investigating, cleaning up or paying the costs of cleaning up such hazardous sites. These parties are referred to as "potentially responsible parties" or "PRPs."

Customer Service Hotline: 1-800-438-2474 On October 14, 1992, EPA included the Site on the National Priorities List ("NPL"), a list of the most serious uncontrolled or abandoned sites at which releases of hazardous substances have occurred or may occur. For a more detailed discussion of the Site background, please see Enclosure 1.

2. "De Minimis " Settlements

This letter also serves as notice to the parties listed on Attachment "A," of the opportunity to participate in a second round de minimis settlement with EPA in connection with the Site. Based on EPA's review of the records pertaining to the Site, you appear to be responsible for a relatively small amount of hazardous substances at the Site. Therefore, you are being offered this opportunity to settle as a de minimis party.

Pursuant to CERCLA, 42 U.S.C. § 9601, et seg., EPA has conducted and overseen a number of activities at the Site in response to the release and/or threat of release of hazardous substances, pollutants, and/or contaminants into the environment, described above and in Enclosure 1. CERCLA not only authorizes EPA to take actions at sites such as the Malvern TCE Superfund Site to protect public health, welfare, and the environment, it also permits EPA to request and require that parties who are responsible for the waste pay to clean up the Site.

Under Section 122(g) of CERCLA, EPA may offer special settlements to de minimis PRPs. Any party who settles its liability to the United States pursuant to this de minimis settlement will not be required to perform Site cleanup work. Instead, the de minimis settlor will pay an amount calculated by EPA to represent that party's proportionate share of costs already incurred and to be incurred at the Site, plus a premium accounting for, among other things, uncertainties in the costs of work not yet performed. In exchange for this cash payment, EPA will agree not to sue or take other civil action against the de minimis settlor with regard to this Site and will provide the de minimis settlor with contribution protection (see discussion on page 4), subject to the settlor's compliance with the terms of the settlement.

The enclosed Administrative Order by Consent ("Consent Order") (Attachment "B") sets forth the terms for concluding your liability to the United States for response costs incurred or to be incurred under CERCLA. EPA has released this Consent Order for your signature. This opportunity to settle under the terms described herein is being offered for a limited time. EPA will accept your signature on the Consent Order for thirty (30) days from receipt of this offer.

In order to assist you in your review of the specific terms of the Malvern TCE Superfund Site de minimis settlement offer, the following information is provided: A. De Minimis Settlement Eligibility

1. Small Waste Contributors

PRPs may be eligible for de minimis settlements if such parties contributed a minimal amount of hazardous substances, in comparison to other hazardous substances at the Site. In addition, the toxicity or other hazardous effects of the hazardous substances contributed by a PRP to the Site must not be significantly greater than that of other hazardous substances at the Site.

2. Volumetric Ranking Summary

Small waste contributors eligible for de minimis settlement have been identified by EPA by utilizing volumetric ranking summaries prepared for the Site. EPA initially prepared two volumetric ranking summaries, a "Generator VRS" and a "Broker/Transporter VRS," dated November 30, 1998 (collectively referred to as " Summaries"). These Summaries are provided in Attachment "C.M As will be described in greater detail below, a PRP is eligible to participate in this settlement if its volumetric contribution of hazardous substance to the Site is at or less than .75% of the total volume attributed to the Main Plant Area ("MPA") of the Site. EPA also has established a de micromis cutoff at 1.5 drums or less.

The attached Summaries were compiled using comprehensive Site documents, including invoices, bills of lading, shipping orders and manifests, obtained by EPA from Chemclene. The Summaries reflect revisions made by EPA to previous draft summaries as a result of EPA's review of ranking challenges received from PRPs. These Summaries also reflect EPA's research into whether certain PRP companies are still in existence. See Attachment "C," "Malvern TCE Volumetric Ranking Summaries Overview and Methodology" ("VRS Overview and Methodology") and "VRS Explanation Sheet," for additional information as to the methodology utilized and information contained in the Summaries.

There will be no further waste reallocation conducted for the purposes of this de minimis settlement.

The Summaries and the new Volumetric Ranking Summary for the Second Round De Minimis Settlement ("New VRS") provide, for each PRP, waste-in volume and percentage information for both the MPA and the Former Disposal Area ("PDA") at the Site. Since all PRP waste into the Site was received and processed by Chemclene in the MPA, EPA has set the de minimis settlement eligibility cut-off at or less than .75% of the total MPA waste volume. Generator PRPs should refer to the "MPA %" column contained in the Generator VRS in order to determine their MPA %. Broker/transporter PRPs should add their MPA % listed on both the Generator VRS and the Broker/Transporter VRS, in order to determine their total MPA %. See Attachment "C," "VRS Overview and Methodology," for additional information as to the information contained in the Generator VRS and Broker/Transporter VRS. Since the preparation of the Summaries, EPA has incurred additional costs for activities at the Site. Consequently, EPA has prepared a New VRS that includes total volumetric information for both Generators and Broker/Transporters. The New VRS incorporates the new higher costs into its cost allocation for each eligible PRP. The New VRS reflects the total .payment amounts for the de minimis parties eligible for this settlement and is provided as Attachment "D."

B. De Minimis Settlement Terms

1. De Minimis Settlement Payment

In order to participate in this settlement, each de minimis PRP must agree to pay the amount listed next to its company in the "Total Payment" column on the New VRS (Attachment "D").

The total payment amount represents each de minimis PRP's PDA and MPA percentage contribution towards past costs incurred by EPA at the Site and estimated future costs to clean up the Site, plus a premium payment. The premium payment of formulation of 50%, subject to a reopener, for this settlement offer has been determined based upon a variety of factors specific to both the Site and the settlement. In addition, for parties who were offered an opportunity to join in the original de minimis settlement, an additional 10% will be included in the premium.

In order to determine a de minimis PRP's total de minimis settlement payment, EPA has divided costs associated with the FDA and the MPA and calculated total payment amounts for each of these areas.

2. Covenant Not to Sue

EPA will provide each settling de minimis PRP with a covenant not to sue. This provision is a promise that EPA will not bring any future legal actions against you regarding the Site and the specific matters identified by the settlement, provided that EPA's information regarding the volume and toxicity of your wastes is correct.

3. Contribution Protection

EPA will provide each settling de minimis PRP with contribution protection. This provision offers you protection from being sued by other PRPs at the Site. Frequently, major waste contributors will sue small waste contributors to recover clean up costs. A de minimis settlement provides protection from such suits that extends to all issues covered by the settlement. C. information to Assist PRPs

1. Information about the Site

The Malvern TCE Superfund Site ("Site"} is located at and near 258 N. Phoenixville Pike, Malvern, East Whiteland Township, Pennsylvania.

From 1952 until 1992, Chemclene Corporation sold and reclaimed industrial cleaning solvents, including trichloroethene ("TCE"); 1,1,1 -trichloroethane ("1,1,1 -TCA"); perchloroethylene ("PCE," also called tetrachloroethene); and methylene chloride ("MEC"). These solvents were used by local industries for degreasing metal parts and other cleaning purposes. Chemclene used a distillation process to remove impurities from the chlorinated solvents. The distilled solvents were then resold to customers for reuse, or resold to other customers. Chemclene utilized two areas of the Site as part of its operations, the Main Plant Area ("MPA") and the Former Disposal Area ("PDA").

The end products of processing waste solvents are the reclaimed solvents and chlorinated still bottoms. The chlorinated waste solvents are listed hazardous wastes pursuant to the Resource Conservation and Recovery Act ("RCRA") and, therefore, the resulting still bottoms are listed hazardous waste. Prior to 1975, Chemclene reportedly buried drums containing the still bottom sludges from the distillation process in the Former Disposal Area/Mounded Area ("FDA"), approximately 1,900 feet southwest of the main plant. The FDA consists of two unlined earthen pits, each approximately 30 feet by 50 feet by 15 feet deep. This area is currently secured by an 8-foot high chain link fence. The Mounded Area, located on the western edge of the FDA, is approximately 8 feet wide by 150 feet long.

Chemclene's activities at the Site have been linked to the presence of volatile organic contaminants in the ground water and soil at the MPA and the FDA and the groundwater of the adjacent Spring Ridge Property. These contaminants include TCE, PCE, 1,1,1-TCA, MEC, 1,1- DCE, among others, and are listed as hazardous substances under 40 C.F.R. § 302.4.

In the spring of 1980, TCE was detected in groundwater from several wells in the vicinity of the Chemclene facility. At this time, Chemclene Corporation began sampling domestic wells in the immediate vicinity of the property. Private domestic wells and on-Site monitoring wells were sampled by Pennsylvania's Department of Environmental Resources ("PADER"), now known as the Department of Environmental Protection ("PADEP"), and Chemclene in June 1980 and July 1981. Analytical results revealed contamination of the underlying aquifer with chlorinated ethenes and related compounds. TCE was detected in wells at concentrations up to 12,600 micrograms per liter ("ug/D> far exceeding the Maximum Contaminant Level ("MCL") of 5.0 ug/1. The Site was listed on the Superfund National Priorities List ("NPL") in September 1983. The contaminated home wells were located south of the FDA, with several located in the Hillbrook Circle residential development. Chemclene furnished activated carbon filter units to twenty (20) residential wells within the Hillbrook Circle Development and conducted periodic sampling of home wells in accordance with its Domestic Well Management Plan until November 1994. In February 1995, EPA assumed control of maintenance activities of the carbon filter units and periodic sampling of the home wells, after it was determined that Chemclene was not following the procedures outlined in its Domestic Well Management Plan. In August 1995, several of the filter systems were upgraded by EPA in response to analytical results from residential well samples that showed contamination was passing through the existing filters into the homes.

In addition to the installation of carbon filters, Chemclene conducted removal actions following the detection of soil and groundvvater contamination in 1980. Debris and approximately 300 drums were removed from the PDA excavations, in a prolonged removal effort from 1981 to 1984. Soils underlying the PDA were excavated to a depth of 15 feet and transported for disposal at a RCRA permitted disposal facility. Additional drums were removed from the Mounded Area in late 1990; however, contaminated soil was left in place.

Four underground storage tanks ("UST's) were removed from the MPA in 1986. Soil samples collected from below the excavation grade of the tanks exhibited elevated concentrations of TCE, PCE, and 1,1,1-TCA. In addition, elevated levels of volatile organic compounds ("VOCs") were detected in soil gas samples collected outside the distillation building in the MPA. These contaminant levels are believed to be related to Chemclene's past practices of discharging contaminated condensate from the recycling distillation process directly onto the ground surface.

As an operating facility, Chemclene entered into a RCRA Corrective Action Order with EPA in 1987. A RCRA Facilities Investigation ("RFI") Work Plan was approved for the Site in 1989. In July 1992, Chemclene withdrew its RCRA Part B Application as a treatment and storage facility, and to EPA's knowledge stopped accepting waste solvents for reclamation.

Chemclene failed to complete the RFI and implement interim corrective measures. As a result, EPA began considering the Site under the Superfund remedial program in November 1993. All existing data was compiled and a report was developed entitled Data Summary Report, April 1995. Based on EPA's review of the existing information, data gaps were identified and EPA was unable to conduct a Human Health or Ecological Risk Assessment. Accordingly. EPA conducted a Remedial Investigation ("RI") to complete the necessary data gathering at the Site. The RI was completed in January 1997 and the Feasibility Study ("FS") in June 1997. The Proposed Plan for a comprehensive Site clean up was issued in June 1997. In November 1997, EPA issued a Record of Decision ("ROD") selecting a final remedy for cleanup of the Site. Available information indicates that Chemclene ceased operations in the Fall of 1999.

In April 1998, EPA notified approximately 250 generator and transporter potentially responsible parties ("PRPs") of their eligibility for a potential Superfund de minimis settlement offer regarding the Site. Additionally, in May 1998, EPA issued Special Notice Letters to approximately 40 non-tfe minimis potentially responsible parties which notified them of their opportunity to resolve their liability with respect to the Site.

In May 1999, EPA and 169 de minimis parties entered into an Administrative Order on Consent, which became effective September 28, 1999. In December 1999, the U.S. District Court for the Eastern District of Pennsylvania entered a Consent Decree between EPA and 35 non-cfe minimis parties. Among other things, the 35 non-cle minimis parties agreed to implement the Remedial Design and Remedial Activity specified in the November 1997 ROD. Attachment A Attachment A

These summaries are attached as Appendix "C." V. ERA'S STATEMENT OF FACTS

4. The Site is located at and around 258 N. Phoenixville Pike. Malvern, Hast Whiteland Township, Chester County, Pennsylvania. A Transcontinental Gas Pipeline Co. natural gas pipeline right-of-way extends along the southern boundary of the Site, with residential areas and areas with natural tbrestation and vegetation bordering the property to the west, north and east. The approximate area of the Site is identified on the map attached as Appendix "B."

5. The Site includes, but is not limited to, a parcel of approximately 5-acres at which Chemclene Corporation ("Chemclene"), from 1952 until 1992. among other things, sold and reclaimed industrial cleaning solvents including trichloroethene ("TCE"), 1,1,1,-trichloroethane, perchloroethylene, and methylene chloride. These solvents were used by local industries for degreasing metal parts and other cleaning purposes. Chemclene used a distillation process to remove impurities from the chlorinated solvents. The distilled solvents were then returned to customers for reuse. The end products of processing waste solvents are the reclaimed solvents and chlorinated still bottoms. The chlorinated waste solvents are listed hazardous wastes pursuant to the Resource Conservation and Recovery Act ("RCRA"), 42 U.S.C. § 6901 et sea,., and, therefore, the resulting still bottoms are listed hazardous waste. Wastes shipped to Chemclene were stored, processed, disposed, and bulk accumulated at the Site for eventual transfer to other locations, and a small amount was directly transshipped to other locations.

6. Chemclene utilized two areas of the Site, the Main Plant Area ("MPA"} and the Former Disposal Area ("PDA"), as part of its business operations. Chemclene utilized the MPA to receive, accumulate, store, and process wastes, including hazardous substances. Wastes, including hazardous substances, also were released and disposed of at the MPA as a result of Chemclene's operations. Chemclene disposed of wastes, including hazardous substances, at the PDA.

7. In the spring of 1980, TCE was detected in groundwater from several wells in the vicinity of the Chemclene facility. Private domestic wells and on-Site monitoring wells were sampled by Pennsylvania's Department of Environmental Resources and Chemclene in June 1980 and July 1981. Analytical results of this sampling revealed contamination of the underlying aquifer with chlorinated ethenes and related compounds. 7

8. Pursuant to Section 105 of CERCLA. 42 U.S.C. § 9605, EPA proposed the Site for listing on the National Priorities List ("NPL"), set forth at 40 C.F.R. Part 300. Appendix "B," by publication in the Federal Register. Final listing on the NPL as the Malvern TCE Superfund Site was in September 1983.

9. Hazardous substances have been or are threatened to be released at or from the Site, including, but not limited to, at or from the MPA and PDA at the Site.

10. Between 1981 and 1986. Chemclene commenced certain activities, including installation of filters on contaminated home wells located within a residential development south of the Chemclene property, PDA debris and drum removal and limited soil excavation, and removal of underground storage tanks and soil sampling at the MPA, to address EPA concerns of contamination at the Site. In 1987, Chemclene entered into a Corrective Action Order pursuant to RCRA (Docket No. RCRA-III-010-CA) with EPA. Chemclene did not complete a RCRA Facilities Investigation of the Site or implement corrective measures at the Site, as required by the RCRA Order.

11. As a result of the release or threatened release of hazardous substances, EPA has undertaken response actions at or in connection with the Site under Section 104 of CERCLA, 42 U.S.C. § 9604, and will undertake response actions in the future. Among other things, EPA:

a. assumed control of maintenance activities of filter units that had been installed on contaminated residential wells located south of the Site and of periodic sampling of residential wells;

b. upgraded residential well filter systems in response to analytical results from well samples that showed contamination was passing through the existing filters into the homes;

c. conducted and completed in January 1997 a Remedial Investigation of the Site;

d. completed a Feasibility Study of the Site in June 1997; and

e. issued a Record of Decision in November 1997 pursuant to which EPA selected a remedy to be implemented at the Site.

12. In performing these response actions, EPA has incurred and will continue to incur response costs. As of October 3, 2000, EPA had incurred $4,776,948.97 in Past Response Costs. EPA may incur Future Response Costs at the Site. 13. EPA has reviewed records describing the transactions of PRPs. including the De Minimis PRPs, in relation to the Site. These records include information describing the amount and nature of waste contributed to the Site. Based upon that review. EPA has determined that each De Minimis PRP. including each De Minimis Respondent II listed in Appendix "A." arranged for disposal or treatment, or arranged with a transporter for disposal or treatment, of a hazardous substance owned or possessed by such De Minimis Respondent II, at the Site, or accepted a hazardous substance for transport to the Site.

14. Information currently known to EPA indicates that each De Minimis PRP. including each De Minimis Respondent II listed in Appendix "A," contributed between 1.6 drums and 0.75% of the total waste sent to the Site, and that the toxic or other hazardous effects of the hazardous substances contributed by each De Minimis PRP, including each De Minimis Respondent II, to the Site are not significantly more toxic than the other hazardous substances at the Site. The Volumetric Ranking Summaries ("VRS") (Appendix "LC") and New Volumetric Ranking Summary for the Second De Minimis Settlement (''New VRS")( Appendix "D") prepared for the Site list, among other things, the estimated volume of waste contributed to the Site by each De Minimis PRP, including each De Minimis Respondent II, and the percentage of waste contributed to the Site by each Respondent in relation to the total estimated volume of waste sent to the Site during the 1968 to 1992 time period. The volumes and percentage shares presented in the VRS and New VRS represent EPA's best estimates and are based on all information currently in EPA's possession.

15. EPA has estimated that the total response costs incurred and to be incurred at or in connection with the Site by the EPA Hazardous Substance Superfund and by private parties is $20,506,099.97. This amount includes $4,776,948.97 in response costs incurred by EPA through October 3, 2000 , and Future Response Costs in the amount of $ 15,729,151.00 (estimated future Site remedial costs in the amount of $15,529,151.00, and EPA future remedial oversight costs estimated to be $200,000.00). EPA has received certain information that indicates these estimated remedial costs could be revised.

16. The total payment required to be made by each De Minimis Respondent II pursuant to this Consent Order is set forth in the New Volumetric Ranking Summary for the Second De Minimis Settlement, attached as Appendix *'D." The total payment to be made by each De Minimis Respondent II represents a minor portion of this total response costs incurred and to be incurred at or in connection with the Site, as referenced in Paragraph 15 of this Consent Order. 17. ERA has identified PRPs other than De Minimis Respondents II. who owned or operated the Site, or who arranged for disposal or treatment, or arranged with a transporter for disposal or treatment, at the Site, of a hazardous substance owned or possessed by such persons.

VI. DETERMINATIONS

Based upon the Statement of Facts set forth above and on the administrative record for this Site, EPA has determined that:

a. the Site is a "facility" as that term is defined in Section 101(9) of CERCLA. 42 U.S.C. §9601(9).

b. each De Minimis Respondent II is a "person" as that term is defined in Section 101(21) of CERCLA, 42 U.S.C. §9601(21).

c. each De Minimis Respondent II is liable within the meaning of Sections 107(a) and 122(g)(l) of CERCLA. 42 U.S.C. §§ 9607(a) and 9622(g)(l).

d. the materials shipped to the Site by the De Minimis Respondents II include "hazardous substances" within the meaning of Section 101(14) of CERCLA, 42 U.S.C. § 9601(14).

e. the past, present or future migration of hazardous substances from the Site constitutes an actual or threatened "release" as that term is defined in Section 101(22) of CERCLA, 42 U.S.C. § 9601(22).

f. the Past Response Costs incurred and Future Response Costs to be incurred in connection with the Site are removal and remedial response costs within the meaning of Section 107(a) of CERCLA, 42 U.S.C. § 9607(a).

g. prompt settlement with each De Minimis Respondent II is practicable and in the public interest within the meaning of Section 122(g)(l) of CERCLA, 42 U.S.C. § 9622(g)(l).

h. as to each De Minimis Respondent II, this Consent Order involves only a minor portion of the response costs at the Site within the meaning of Section 122(g)(l) of CERCLA, 42 U.S.C. § 9622(g)(l).

i. each De Minimis Respondent II is eligible for a de minimis settlement pursuant to Section 122(g)(l)(A) of CERCLA, 42 U.S.C. § 9622(g)(l)(A), 10

since both the amount and the toxicity or other hazardous effects of the hazardous substances contributed to the Site by each De Minimis Respondent II is minimal in comparison to other hazardous substances at the Site.

VII. ORDER

Based on the foregoing Statement of Facts and Determinations by EPA. in order to reach an expedited de minimis settlement in connection with the Site, in consideration of. and in exchange for, the promises, mutual undertakings, and covenants set forth herein, and intending to be legally bound hereby, EPA and the De Minimis Respondents II agree, and EPA hereby Orders, that the De Minimis Respondents II shall pay their cost share as set forth below: a. Within thirty (30) days of the effective date of this Order, each De Minimis Respondent II shall pay its volumetric share of the cost basis of $20,506,099.97 ($4,776,948.97 in Past Response Costs; and $15,729,151.00 in Future Response Costs, which include EPA future remedial oversight costs in the amount of $200.000.00). The amount to be paid by each settling De Minimis Respondent II is set forth under the Total Payment Column included in the New Volumetric Ranking Summary for the Second De Minimis Settlement, attached as Appendix "D." b. The de minimis settlement payment required of each De Minimis Respondent II, as referred to in Paragraph 19.a. of this Order, also includes a settlement premium. This premium is designed to cover risks and uncertainties associated with this settlement, including but not limited to. the risk that total response costs incurred or to be incurred at or in connection with the Site by the EPA Hazardous Substance Superfund. or by any private party incurring Remedial Costs, will exceed the estimated total response costs, upon which Respondent's payments are based. However, the premium is not designed to cover the risk that Remedial Costs will exceed $25 million, and consequently, the Covenant Not to Sue is subject to the Reservation of Rights in Paragraph 28. c. De Minimis Respondents II, Maida Development Corporation and McHugh Railroad Maintenance Equipment Company, as identified in Appendix "D," were previously offered by EPA an opportunity to participate in AOC I, but did not participate in that settlement. II

d. De Minimis Respondents II, American Electronics Laboratories, Boekel Scientific Industries, Inc.. Elco Corporation. Ervins Crafts. Photofabrication Chemical and Equipment Company, and R & E Martin, previously were offered by EPA an opportunity to participate in AOC I; however, EPA's records do not reflect that this occurred.

VIII. PAYMENT

20. Payments by De Minimis Respondents II shall be made as follows:

a. Within thirty (30) days of the effective date of this Consent Order, each De Minimis Respondent II shall pay the amount listed for the De Minimis Respondent II in the New Volumetric Ranking Summary for the Second De Minimis Settlement, attached as Appendix "D " to this Consent Order and as specified in Section VII (Order), above.

b. Any De Minimis Respondent II may make payment in two equal installments, the first due and payable within thirty (30) days of the effective date of this Consent Order, and the second due and payable within one year of the effective date of the Consent Order.

c. Each payment shall be made by certified or cashier's check made payable to "EPA Hazardous Substance Superfund." Each check shall reference the name and address of the party making payment, the Site name, the EPA Region and Site Spill ID Number 03-91, and the EPA Docket Number for this action, and shall be sent to:

Charlie Root (3HS21) Remedial Project Manager United States Environmental Protection Agency Region III 1650 Arch Street Philadelphia, PA 19103-2029 21. EPA shall deposit any de minimis settlement proceeds received into a Malvern TCE Superfund Site special account within the EPA Hazardous Substance Superfund. The proceeds can be retained and used by EPA. or by a party designated by EPA, to conduct or finance response action at or in connection with the Site and/or, at EPA's discretion, can be transferred to the EPA Hazardous Substance Superfund as reimbursement for response costs incurred at or in connection with the Site by the EPA Hazardous Substance Superfund. Any amounts remaining in a Malvern TCE Superfund Site special account shall be transferred by EPA to the EPA Hazardous Substance Superfund.

22. Any amounts due and owing by a De Minimis Respondent II pursuant to the terms of this Consent Order but not paid in accordance with the terms of this Consent Order shall accrue Interest, as defined in Paragraph 3.j. of this Consent Order, which shall be assessed to such De Minimis Respondent II.

26. If this certification is subsequently determined to be false, such De Minimis Respondent II shall forfeit all payments made pursuant to Section VIII of this Consent Order. Such forfeiture shall not constitute liquidated damages and shall not in any way foreclose the United States' right to pursue any other causes of action arising from such De Minimis Respondent II's false certification. Providing false, fictitious, or fraudulent statements or representations to the United States is punishable as a crime under 18 U.S.C. § 1001.

XI. COVENANT NOT TO SUE BY UNITED STATES

27. In consideration of the payments that will be made by the De Minimis Respondents II under the terms of this Consent Order, and except as specifically provided in Section XII (Reservations of Rights by United States), the United States covenants not to sue or take administrative action against any of the De Minimis Respondents II for civil liability for reimbursement of Response Costs or for injunctive relief pursuant to Sections 106 or 107 of CERCLA, 42 U.S.C. §§ 9606 or 9607, or for injunctive relief pursuant to Section 7003 of the RCRA, 42 U.S.C. § 6973, with regard to the Site. With respect to present and future liability, this covenant not to sue shall take effect for each De Minimis Respondent II upon receipt of that De Minimis Respondent II's payment as required by Section VIII. With respect to each De Minimis Respondent II, individually, these covenants are conditioned upon complete performance by such De Minimis Respondent II of all obligations under this Consent Order, and the veracity and completeness of the information provided to EPA by such De Minimis Respondent II relating to each De Minimis Respondent II's involvement with the Site. These covenants shall be null and void with respect to any individual De Minimis Respondent II that fails to perform all obligations under this Consent Order in a timely and complete manner, or has provided materially false, incomplete, or incorrect information in 14

such De Minimis Respondent II's Certification under Section X of this Consent Order. These covenants extend only to De Minimis Respondents II and do not extend to any other person.

Total 71 432.98 $716,177 Attachment C Malvern TCE Volumetric Ranking Summaries/Overview and Methodology

This document provides a general overview and describes methodology utilized by EPA in the preparation of the Malvem TCE Superfund Site ("Site") Volumetric Ranking Summaries dated November 30, 1998 ("Summaries"). A description of* minimis settlement eligibility and requirements also is provided.

I. VOLUMETRIC RANKING SUMMARIES: OVERVIEW

The volumetric ranking summaries reflect revisions made by EPA to draft Site volumetric ranking summaries prepared by EPA and distributed to potentially responsible parties ("PRPs") for the Site on November 3, 1997 and April 30, 1998. Among other things, the attached Summaries incorporate information obtained by EPA as a result of: a) EPA's review and/or reconsideration of challenges submitted by PRPs to EPA to prior draft Site volumetric ranking summaries; b) review by EPA of Site records; and c) EPA research into the continued existence- and viability of various PRPs identified in connection with the Site.

A. Generator and Transporter Volumetric Ranking Summaries

EPA has prepared two volumetric ranking summaries for the Site: a Generator Volumetric Ranking Summary ("Generator VRS") and a Broker/Transporter Volumetric Ranking Summary ("Broker/Transporter VRS"). As a result of EPA's review of Site records documenting transactions between PRPs and Chemclene, a number of brokers/transporters have been identified. The Summaries are intended to reflect all generator and broker/transporter PRP transactions at the Site and to attribute to each generator and broker/transporter identified at the Site, the full volume of waste into the Site contributed by each, as reflected in Site records. All documented shipments of waste to the Site are reflected in the Generator VRS; transactions involving brokers/transporters also are reflected in the Broker/Transporter VRS. See Section II.D. of this Overview and Methodology for additional details relating to generator and broker/transporter transactions.

B. Information contained in Summaries

In general, the attached Summaries provide the following for each PRP:

1. The volume of waste each PRP contributed to the Site.

This volunv reflects, for each PRP, the total volume of waste, as measured in 55-gallon drum units, each PRP contributed to the Former Disposal Area ("FDA'O and the Main Plant Area ("MPA") of the Site, areas used by Chemclene as part of its operations. These amount are reflected in the "PDA Drums" and the "MPA Drums" columns of the Summaries. See Section II.B.3. of this Overview and Methodology for details regarding EPA's methodology

AR000202 relating to the PDA and MPA.

2. The percentage of waste each PRP contributed to the PDA and MPA.

This percentage reflects each PRP's percentage of waste contributed to the PDA and MPA. relative to the percentage of total waste sent by all PRPs to the PDA and MPA, respectively. These percentages are reflected in the "PDA %" and "MPA %" columns of the Summaries.

3. The revised ercentae of waste each PRP contributed to the PDA and

EPA has determined that some Site PRPs are no longer financially viable corporate entities, and, therefore, are Site "orphans" that will not participate in any de minimis settlement with EPA. These orphan shares have been apportioned on a pro rata basis among non-orphan Site PRPs. This apportionment is reflected in the "Revised PDA %" and "Revised MPA %" columns of the Summaries.

4. be minimis settlement payment required of each settling de minimis PRP.

The Summaries include each eligible de minimis PRP's share of costs such PRP will be required to pay in order to participate in a de minimis settlement with EPA. The total payment required of each de minimis PRP is reflected in the 'Total Payment" column of the Summaries. The total payment required of each PRP includes each PRP's share of costs associated with the PDA and MPA, as set forth in the "PDA Cost" and "MPA Cost" columns of the Summaries. In addition, the total payment required of each PRP includes a premium payment assessed by EPA to take into account remedy and cost risks assumed by EPA in connection with the Site and the de minimis settlement. The premium is not assessed on EPA's ^ past costs, but only on the estimated future costs. Premiums are reflected in the "PDA Premium" and "MPA Premium" columns of the Summaries. See the Explanation Sheets attached to the Summaries for additional details regarding the information contained in the Summaries. II. METHODOLOGY UTILIZED BY EPA WHEN CREATING THE VOLUMETRIC RANKING SUMMARIES • • » A. Documents Used The Summaries prepared for the Site ,«n compiled using Site documents obtained by EPA from Chemclene. These documents, which include invoices, receipts, purchase orders manifests, and a number of other related documents, refer to transactions dattng from 1968 unul 1992 between Chemciene and its customers. These documents memorialize a number of

HR000203 different types of transactions, reflecting the varied nature of Chemclene's business and Chemclene's-changing billing practices. Examples of the transactions reflected in the documents include, but are not limited to:

1. Shipment of solvent and non-solvent waste from waste generators to Chemclene for processing and/or disposal;

2. Transshipments of solvent and non-solvent waste from Chemclene to other treatment, storage and disposal facilities;

3. Transfer of reclaimed solvents from Chemclene back to the original waste generator;

4. Transfer of raw or reclaimed solvent from Chemclene to customers;

5. Return of unused solvents or unused empty drums from customers to Chemclene;

6. Transfer of empty drums from Chemclene to waste generators to be filled up with wastes;

7. Purchases of raw materials by Chemclene;

8. Sale of services (such as waste sampling or transport services) by Chemclene to customers; and

9. Charges by Chemclene for off-Site disposal of still-bottoms resulting from the on-Site process ig of wastes.

B. Interpretation of Documents

1. Waste into the Site

Based upon its understanding of Chemclene's operations, EPA has assumed that any unit of waste snipped to the Site was just as likely to have become a contaminant in the environment as any other unit of waste. In preparing the volumetric ranking, EPA has examined carefully the Site documents to determine which transactions indicate the shipment of waste to Chemclene, and to determine the volume of these shipments. The majority of transactions reflected in the Summaries are documented by a Chemciene invoice. In many instances, however, there are other documents that reveal the

AR00020U details of the transaction more clearly than the invoice. For most transactions, the nature of the transaction is clear regardless of which document is examined. However, in some cases the nature of the transaction becomes clear only by comparing two or more documents. In all instances, EPA looked at all of the documents related to a transaction before determining how to interpret the documents.

2. Time Period Summari2e4

For purposes of preparing the VRS, EPA reviewed and summarized existing Site documents, which refer to the 1968 to 1992 time period. EPA is aware that Chemclene operations at the Site commenced in approximately 1952. However, since EPA does not have information relating to the 1952 to 1968 period of Chemclene operations, EPA has made no assumptions regarding waste transactions during that time period, and has not attempted to summarize waste transactions during that time period. Available information indicates that Chemclene withdrew its Part B Application submitted pursuant to the Resource Conservation and Recovery Act ("RCRA"), 42 U.S.C. § 6901 a sjBft., to operate as a treatment and storage facility, and stopped accepting waste solvent for reclamation in July 1992.

3. Main Plant Area and Former Disposal Area

Information available to EPA indicates that Chemclene utilized both the MPA and FDA as part of Chemclene's operations. At all times during its operation, until approximately July 1992, Chemclene utilized the MPA to receive, accumulate, store, and process wastes, including hazardous substances. All wastes sent to the Site initially went to the MPA. Wastes, including hazardous substances, also were released and disposed of at the MPA as a result of Chemclene's operations. Chemclene also disposed of wastes, including hazardous substances, at the FDA. Chemclene claims that disposal at the FDA ceased when new management took over the business in approximately August 1975, at which point Chemclene discontinued use of the FDA and disposed of waste generated from the reclamation process off-Site. Based upon the foregoing information, when preparing the volumetric ranking summaries for the Site, EPA counted all waste transactions between Chemclene and PRPs during the 1968 to August 1975 time period as waste into both the MPA and the FDA. EPA has counted waste transactions between Chemclene and PRPs after August 1,1975, only as waste into the MPA. The distinction between the MPA and the FDA is meaningful in two ways: a) in the setting of the cut-off delineating which PRPs may be eligible to jfcrticipate in a de minimis settlement; and b) in determining the amount of monies eligible de minima PRPs will be required to pay in order to participate in a de minimis sctti nent with EPA.

Each PRP's eligibility for dt minimis status will be determined using the percentage of the total waste sent to the Site by the PRP. This percentage is set forth in the

ARO'00205 "MPA %" column of the Summaries, since all waste into the Site was received and processed bv Chemclene at the MPA.

The Site remedy selected by EPA in its Record of Decision dated November 26, 1997, has provided for distinct remedies for the MPA and PDA. Even though significant aspects of the cleanup of the MPA and the PDA may be combined, EPA believes that costs of the remedy can be allocated fairly between the two areas. EPA separately has calculated the de ' minimis settlement payments of each eligible de minimis PRPs for the MPA and PDA and has added these amounts to obtain a "Total Payment" required.

4. Transshipments

Based upon EPA's understanding of Chemciene's operations and review of Site records, EPA has determined that some waste received by Chemclene at the Site likely was transhipped off-Site, e.g. shipped off-Site for processing and/or disposal. Information available to EPA indicates that Chemclene often would containerize and store at the Site these wastes for off-Site shipment at some later date, and that releases or threatened releases of these wastes at the Site occurred as a result of Chemciene's practice.

EPA did not count as waste into the Site, transactions that appear to reflect that waste was sent off-Site for processing or disposal only in those instances where EPA could document, typically through its review of waste manifests, that such wastes remained in their original shipping containers and were not bulk-stored or otherwise opened and handled on-Site, prior to off-Site shipment

C. Units of Measurement

To the extent applicable, EPA has prepared the volumetric ranking in accordance with OSWER Directive 9835.16, "Guidance to Preparing and Releasing Waste-In Lists and Volumetric Rankings to PRPs Under CERCLA," dated February 22,1991. The most common unit of shipment was the 55-gallon drum, and therefore all other units found in the documentation were converted to 55-gallon drum units. When units were listed in gallons or other units of volume, simple mathematics was used to convert into drum units. Por those entries with less than 55 gallons, a decimal was used. For example, if the documents indicated ten 30- gallon containers of waste shipped to Chemclene, then the 300 gallons of waste would be divided into 55-gaJlon units yielding 5.45 drums. In a comparatively few instances, shipments of waste were listed in units of weight or other units. In these instances EPA used the following assumptions:

• For those entries listing pounds as the measurement unit, EPA's standard conversion factor of 1 gallon - 8.33 pounds was extrapolated to 55 gallons * 458 pounds.

AR000206 I can * 5 gallons.

1 bottle - 1 gallon.

1 lab pack = 1 gallon.

In addition, a small number of transactions indicated the shipment to Chemclene of "empty" drums or other containers which are listed as "used" or "dirty" or some other language indicating that the container had at one time contained waste. In these instances EPA assumed that the container contained 3% of its capacity in hazardous wastes, based upon the definition of "empty" in the RCRA regulations. See 40 C.F.R. § 261.7.

D. BrokersH'ransporters

As a result of its review of Site documents, EPA has identified a number of PRPs that appear to have acted as brokers and/or transporters of waste to the Site. EPA has included broker/transporter PRPs in the Summaries.

Most Site records that identify brokers/transporters refer to brokers/transporters with whom it appears Chemclene dealt directly. A number of Site records, for example, reflect that Chemclene directly billed and/or credited such brokers/transporters with regard to waste transactions at the Site.

The Site records that refer to broker/transporter PRPs identify two types of transactions: 1) transactions in which a broker/transporter appears to have arranged for the transport or disposal of or transported waste generated by a third-party to the Site, and in which both the broker/transporter and the generator are expressly identified in the corresponding Site record; and 2) transactions between a broker/transporter and Chemclene where no third-party generator has been identified. In the latter instance the documentation is the same as for any other generator, and the party listed on the documentation is thus treated as a generator for those transactions, even if the same party may have acted as a broker/transporter in other instances.

Consistent with OSWER Directive 9835.16, whenever a Site record reflects a transaction in which both a generator PRP and a broker/transporter PRP are expressly identified, EPA has attributed the waste volume referred to in each such transaction to both the generator and the broker/transporter for purposes of compiling waste-in information contained in the Summaries. However, EPA has counted the total waste referred to in these transactions only once for purposes of determining total waste contributed to the Site by all PRPs.

The Generator VRS summarizes waste volume information: l)"w each generator PRP; and 2) for each broker/transporter PRP only with regard to those brokei/transporter transactions with Chemclene for which r*o corresponding third-party generator has been identified. As set forth above, in cases where a third-party generator is riot identified, the party named on the

AR000207 invoice or other documentation has been treated as a generator for that transaction even if the party involved has been identified as a broker/transporter for other transactions.

The total waste contributed to the Site by all PRPs appears at the end of the Generator VRS.

EPA has prepared a separate Broker/Transporter VRS in order to summarize those waste- in transactions in which both a broker/transporter and a generator have been identified. The waste volume reflected in these transactions also has been summarized for each corresponding generator in the Generator VRS. By preparing a separate Broker/Transporter VRS, EPA can attribute to each broker/transporter the waste reflected in these transactions, but avoid double- counting the waste when determining total waste contributed to the Site by all Site PRPs (as reflected in the Generator VRS).

. Broker/transporter PRPs should refer to both the Generator VRS and the Broker/Transporter VRS in order to determine waste volume and percentage information.

For purposes of a die minimis settlement, both the generator and the broker/transporter * will be liable for the full amount of the waste in a transaction involving both a generator and a broker/transporter. In other words, for some shipments two parties both will be fully liable for the share of the cleanup represented by those drums. However, parties can avoid full liability if the broker/transporter and the generator cooperate with each other and agree to an allocation between themselves. In such instances, the broker/transporter and the generator may jointly senle with EPA for the full amount of the wastes in question, and avoid having to each pay for the wastes.

E. Grouped PRPs

Based upon information obtained by EPA, EPA has concluded that some Site PRPs are related or successor entities to other Site PRPs. EPA has grouped related/successor entities in the attached Summaries. For each such grouping, EPA has determined the grouping's total volume and percentage liability at the Site based upon the combined totals of each related/successor entity. Total volume and percentage information for each grouping is set forth in the Generator VRS that is arranged alphabetically by PR?. Total volume and percentage information foe each grouping is set forth under the name of the PRP grouping and appears in bold print Volume and percentage information for each separate related/successor PR? member of the grouping alsorra set forth in the Summaries.

F. Qrphan PRPa

When a PRP is unable to pay all or part of its allocated shar* of a cleanup, EPA may allocate such a share among the viable PRPs in the same ratio aSyOther cleanup costs. Pursuant to EPA's "Orphan Share" policies, EPA, under certain circumstan/es, may pay (from the

AR000208 Superfund) a portion of the shares of PRPs that are completely non-viable. Orphan share funding may be available only to PRPs that agree to implement and ftind remedial actions at a site, and not to de minimis PRPs. De minimis PRPs may be asked to pay on a pro rata basis for any shares for which the orphan PRPs are unable to pay. In addition, the de minimis premium will take into consideration the likelihood that additional such shares will be identified subsequent to the conclusion of the de minimis settlement

When EPA has been able to identify a PRP as an orphan in the attached summaries, EPA has included for each such PRP, total volume and percentage information. EPA does not anticipate that Site orphans will participate in the de minimis settlement or otherwise pay monies towards Site remediation. Therefore, EPA has not included payment information for any Orphan. In addition, EPA has revised each non-Orphan PRP percentage ("Revised PDA %" and "Revised MPA %"), reflecting each non-orphan PRPs pro rata payment share for each Site orphan.

The calculation of the revised percentages has been done on a transaction by transaction basis. If a transaction involves an orphan generator, then the transaction was checked to determine if there was a broker/transporter for the same transaction. A transaction has been divided on a pro rata basis among the remaining PRPs only if there is neither a viable generator nor a viable broker/transporter for the transaction.

III. DE MINIMIS SETTLEMENT

A. De Minimis Cutoff

EPA has established a cut-off for de minimis settlement eligibility using a percentage of the total waste sent to the Site by the PRP. A PRP is eligible to participate in a de minimis settlement if its volumetric contribution of hazardous substances to the Site is at or less than 0.75% of the total volume attributed to the MPA. Pre-August 1975 percentages that have been assigned for the PDA have not been considered by EPA when establishing the de minimis settlement eligibility cutoff. However, such percentages have been considered by EPA when determining the amount of money each de minimis PRP will be asked to pay if it desires to settle.

EPA has also established a de micromis cutoff at 1.5 drums or less. EPA does not foresee a need for settlements with de micromis parties. EPA will, however, pursue settlements with de micromis parties if there is a threat of, or an actual suit by, other PRPs at the Site.

B. DC Minimis Payments *

The attached Summaries contain de minimis settlement payment informatio' for each eligible de minimis settlement EPA has divided the costs of the selected remedy, * set forth in the ROD, between the MPA and PDA, aad has determined each de minimis PRP's required settlement payments for each of these areas of the Site. A PRP's required de minimis payment is

8

AROOQ209 determined based upon its revised percentages for the PDA and the MPA. These revised percentages are then applied to the total costs estimates for the MPA and the PDA.

As of June 17,1997, EPA incurred approximately $2,214,705.00 in response costs ("Past Response Costs**) at or in connection with the Site. Since EPA incurred the Past Response Costs as a result of activities that pertained to both the PDA and MPA, EPA has attributed one-half ($1,107,352.00) of the Past Response Costs to FDA costs and the other one-half ($1,107,352.00) to MPA costs. EPA has estimated future Site costs associated with cleanup and EPA oversight of the Site to be approximately $15,729.151.00 ($15,529,151.00 in remedial costs; $200,000.00 in EPA remedial oversight). Of that amount, approximately $8,155,725.00 has been attributed by EPA to cleanup of the FDA ($8,055,725.00 in remedial costs; $100,000.00 in EPA remedial oversight). Future costs associated with cleanup and EPA oversight of the MPA are approximately $7,573,426.00. ($7,473,426.00 in remedial costs; $100,000.00 in EPA remedial oversight).

EPA has assessed a premium, which each d* minimis PRP must pay in addition to each PRP's percentage of FDA and MPA costs, in order to participate in the de minimis settlement with EPA. The premium is intended to take into account a number of Site factors and risks, . * including additional remedial action and potential response cost overruns, that EPA may encounter when settling with dt minimis PRPs. EPA has established a premium of 50% in this, matter, i.e. a multiplier of .50.

Dear Mr. Minnick, This is to confirm ojcr conversation regarding the Trlchlorethylene from Americat Electronics Laboratories, Inc. The 9 drums (72-1*1) of spent Trichlorethylene are acceptable for reclaimation. The 2 drums (72-1-8),while they were not used, they off color resulting from rust in the drums and will have to be reclaimed to bring them back to specification. In this way, they too are acceptable* Per our agreement, after reclaimation, the residue will be returned to you for proper disposal.

MILACRON • EXCEPTIONAL RANCIDITY CONTROL - no offensive odors; FEATURES long fluid life minimizes concentrate usage and downtime AND spent in recharging a system. • EFFECTIVE LUBRICATION AND COOLING - a combination BENEFITS of chemical lubricants and wetting agents provides good machining and grinding properties; keeps parts and tools cool; extends tool life; allows high speeds and feeds that increase production.

• GOOD SETTLING PROPERTIES — efficiently settles chips and grit; produces a good cake on positive filters which removes recirculating fines and also lowers media usage; parts and machines stay clean.

• STABLE pH — contributes to good rust and rancidity control; lessens the need for additives to maintain performance in dif- ficult systems.

• ORGANIC AND INORGANIC (NONNITRtTE) CORROSION INHIBITORS — protect machines and parts from rust.

• PLEASANT TO USE — no smoke; no slippery film on parts, machines or floors; low misting; mild to the skin when used as recommended; good foam control; no ammonia odors. • NO NITRITE C • STABLE — easy to use; excellent for central systems.

• CIMCOOL FIVE STAR 40 can be recycled for reuse by the CIMCOOL FULL CYCLE1" Module.

Dear Mr. Lagowskt:

This Is in answer to your phone call of several weeks ago when you asked for information regarding the removal of waste Trichtoroethylenefrom K-D Tool by Chemclene.

Our records indicate the following dates of removal arid Quantity removed 11/5/82 20 drums 5/20/83 11 drums 12/13/83 8 drums 6/20/84 10 drums 4/11/85 15 drums As you may know, this material was brought back to our facility in Malvern where H was recycled through distillation. The clean solvent was sold to some of our customers, while the still bottoms were Incinerated.

Please let me know if you need any additional information or have any questions.

Mr. Paul Lagowski Eascol/K-D Tool 3575 Hempland Road Lancaster, PA 17604 Dear Mr. Lagowski :

It was a pleasure meeting you and discussing your waste disposal problems. We have sampled your waste trichlor- ethylene and have taken a long, hard look at your situ- ation. Your problem with this waste stream is that your supplier refuses, or at the very least, is hesitent to provide disposal service. We feel that a distributor of chlorinated solvent should be responsible enough to help thjeir customers on the waste side of their business. We have done this on a regular basis for many companies for over thirty years, regardless of the quality of waste. If Chemclene were to remedy your present situation, our service would really be to your present supplier; our competition. Therefore, we re- spectfully decline to bid on the removal of your waste trichlorethylene and contaminated solids. If you have any questions about our position, please call. As to your future need for disposal of large carbon water filters, we suggest that large carbon water filters, we suggest that your situation is much the same. If your supplier can1t offer disposal as a service, they are only giving you half of what you need. The only alterna- tive we might suggest is Resource Technology Services of Devon, PA. or Eldredge Inc., of West Chester, PA. These are both competent disposal firms. We wish you good luck. Sincerely,

JL/cm PHONE: 1215) 644-29B6

Mr. Park Appler K-D Tools 3575 Hempland Road Lancaster, Pa. 17604 Dear Mr. Appler, We are pleased to present you with the following proposal for your consideration. Chemclene can supply you with virgin trichlorethylene in the following lot sizes with corresponding prices; One to ten 55 gallon drums ~ $.3580 per pound. Eleven or more 55 gallon drums - $.3180 per pound. Chemclene is also capable of delivering solvent in bulk quantities. We cnn supply you with a storage tank at no charge. Delivering virgin trichlorethylene to such a tank would lower the price to $.2860 per pound. As you know, Chemclene is a licensed transporter and treatment storage facility for hazardous waste (EPA ID# PAD01 4353445) . There- fore it always is our desire to serve customers in both waste recovery and disposal and supply. We have recently sampled your waste trichlorethylene. Our analysis shows we can remove and reclaim/ dispose of this material for the cost of $58.00 per 55 gallon drum. When handling waste material, we act with the strictest accordance to the law. Therefore all drums of waste must have proper bungs, normal shape and show no sign of possible leakage. Our driver is the final judge of drum integrity. We will supply labels and manifests for proper documentation. We thank you very much for this opportunity and look forward to be- ing of service to K-D Tool. Sincerely, f]
