ENVIRONMENTAL PROTECTION AGENCY

[FRL-5926-5]

Notice of Availability of and Initiation of a 30 Day Public 
Comment Period for Two Administrative Orders on Consent for de minimis 
Waste Contributors and One Administrative Order on Consent for a de 
micromis Waste Contributor Pursuant to the Comprehensive Environmental 
Response Compensation and Liability Act (CERCLA)

    Notice is hereby given that on October 15, 1997, 3 administrative 
orders on consent (``Orders'') between the United States Environmental 
Protection Agency, Region VIII and various parties potentially 
responsible for costs incurred by the United States for cleaning up the 
Summitville Mine Superfund Site (collectively, ``the Settling 
Parties'') were approved by the Assistant Attorney General of the 
Department of Justice, Environment and Natural Resources Division, on 
behalf of the Attorney General of the United States.
    Because of the minimal nature, by volume and toxicity, of the 
hazardous substances allegedly contributed by the Settling Parties to 
the Site, EPA determined that the Settling Parties are eligible for 
either a de minimis or de micromis settlement in accordance with 
Section 122(g) of CERCLA.
    The first settlement is a de micromis Order with Newmont 
Exploration Limited, Newmont Mining Corporation, and Newmont Gold 
Company (collectively, ``Newmont''). It settles Newmont's potential 
liabilities under CERCLA Sections 106 and 107 and RCRA Section 7003 for 
extremely limited historic exploration activities Newmont undertook at 
the Site. Because of the minuscule nature of Newmont's contribution of 
waste at the Site, and in accordance with EPA guidance, EPA is entering 
into this without requiring the payment of a settlement amount.
    EPA is also entering into 2 de minimis Orders--one with ASARCO, 
Inc. and one with ARCO Environmental Remediation, L.L.C. These Orders 
settle ARCO and ASARCO's potential liabilities under CERCLA Sections 
106 and 107 and RCRA Section 7003 for the limited historic exploration 
activities they undertook at the Site. ASARCO and ARCO are paying the 
United States settlement amounts of $86,052.73 and $95,000, 
respectively. All 3 Orders are based on the respective applicable EPA 
model Orders.
    EPA Region VIII will receive comments relating to the proposed

[[Page 62596]]

Orders for a period of thirty days from the date of publication of this 
notice. Comments should be addressed to Nancy Mangone, Enforcement 
Attorney (8ENF-L), U.S. EPA Region VIII, 999 18th Street, Denver, 
Colorado 80202 and should refer to the Summitville Mine Superfund Site, 
EPA Docket Nos. CERCLA-VIII-98-02, CERCLA-VIII-98-03, and CERCLA-VIII-
98-04. In accordance with Section 7003(d) of RCRA, 42 U.S.C. 6973(d), 
commenters may request a public meeting in the affected areas.
    The proposed Orders may be examined in person at the Superfund 
Records Center, EPA Region VIII, 999 18th Street, Suite 500, Denver, 
Colorado 80202, (303) 312-6489. A copy of each Order may also be 
obtained by mail from the EPA Region VIII Superfund Records Center 
(8EPR-PS) at the address listed above. In requesting a copy, please 
refer to the referenced case and number. There is no cost for 
requesting this document.

the Parties are:
    a. to reach a final de micromis settlement between the Parties with 
respect to the Site pursuant to Section 122(g) of CERCLA, 42 U.S.C. 
9622(g), which resolves Respondents potential civil liability under 
Sections 106 and 107 of CERCLA, 42 U.S.C. 9606 and 9607 and Section 
7003 of the Resource Conservation and Recovery Act, as amended, 42 
U.S.C. 6973, for injunctive relief with regard to the Site, and for 
response costs incurred and to be incurred at or in connection with the 
Site, thereby reducing litigation relating to the Site;
    b. to simplify any remaining administrative and judicial 
enforcement activities concerning the Site by eliminating the 
potentially responsible parties covered by this Order from further 
involvement at the Site; and
    c. to protect Respondents, and to the extent provided herein, their 
affliates, successors and assigns, from any lawsuit a potentially 
responsible party could bring against them for response costs incurred 
and to be incurred at or in connection with the Site and to provide 
full and complete contribution protection for Respondents, and to the 
extent provided herein, their affliates, successors and assigns, with 
regard to the Site pursuant to Sections 122(f)(2) and 122(g)(5) of 
CERCLA, 42 U.S.C. 9622(f)(2) and 9622(g)(5).

III. Definitions

Reservoir-The area below the Terrace Reservoir which has been impacted 
by contamination transported by the Alamosa River and irrigation 
canals.
    United States shall mean the United States of America, including 
its departments, agencies and instrumentalities.

IV. Statement of Facts

    4. The United States Environmental Protection Agency (EPA) 
initiated removal response actions at the Site on December 18, 1992 to 
address releases or threatened releases of hazardous substances into 
the Alamosa River and surrounding environment pursuant to the 
President's authority under Sections 104 and 106 of the Comprehensive 
Environmental Response, Compensation, and Liability Act of 1980, as 
amended by the Superfund Amendments and Reauthorization Act of 1986, 
Pub. L. 99-499, 42 U.S.C. 9604 and 9606 (CERCLA).
    5. On May 31, 1994, EPA listed the Site on the National Priorities 
List as a result of releases or threatened releases of hazardous 
substances at or from the Site.
    6. On December 15, 1994, EPA issued four Interim Records of 
Decision selecting the interim remedial actions to be implemented for 
the following activities and/or areas at the Summitville Mine Site: 
Water Treatment (WT IROD), Reclamation, the Heap Leach Pad (HLP IROD) 
and the Cropsy Waste Pile, Beaver Mud Dump/Summitville Dam Impoundment, 
and Mine Pits (CWP IROD).
    7. As of March 31, 1997, the United States incurred approximately 
$109 million in response costs responding to the release or threatened 
release of hazardous substances at or in connection with the Site. The 
United States continues to incur response costs in responding to the 
release or threat of release of hazardous substances at or in 
connection with the Site.
    8. Newmont Exploration Limited (NEL) conducted extremely limited 
exploration activities at the Site. NEL was previously a wholly owned 
subsidiary of Newmont Mining Corporation and is currently a wholly 
owned subsidiary of Newmont Gold Company.
    9. Newmont Exploration Limited leased some property within the Site 
for approximately seven months from June 1953 to January 1954. Pursuant 
to the lease, limited exploratory activities were conducted, including 
conducting nonintrusive geophysical surveys of the area, collecting 
small surface soil and rock samples for assaying, drilling 
approximately nine small diameter exploratory holes and conducting 
limited reconnaissance examinations of portions of the underground mine 
workings. Exploratory drilling activities such as those conducted at 
the Site are designed to collect core samples to evaluate the geology 
of the area. Respondents assert that such exploratory activities did 
not generate mine wastes.
    10. The total volume of waste rock, tailings and other mine waste 
(including the Heap Leach Pad) requiring remediation at the Site is 
approximately 11 million cubic yards. According to the WT IROD, 
approximately 321,000 pounds of copper per year, if left untreated, 
would contaminate the receiving waters surrounding the Site, including 
the Wightman Fork and Alamosa River. EPA has determined parties are 
eligible for a de minimis settlement if their contribution of mine 
waste and metals loading is equal to or less than 3% of the total 
volume of hazardous substances contributed to each of these media. The 
Respondents' contribution of hazardous substances to these media is 
below the 3% de minimis cut-off established by EPA for the Site. De 
micromis parties are parties that have generated less than .0001% of 
the hazardous substances found at the Site. Respondents' alleged 
contribution is less than .0001% of the hazardous substances found at 
the Site.
    11. Based on information currently known to the United States, EPA 
has calculated the Respondents' de micromis eligibility as follows: 
Respondents assert that the activities of NEL did not contribute any 
mine wastes to the Site. Even assuming a worst case scenario where all 
of the materials generated by NEL's exploration activity were deposited 
at the Site, EPA has estimated that the amount of hazardous substances 
allegedly contributed to the Site by Respondents constitutes 
substantially less than .0001% of the total volume of waste rock, 
tailings or mine waste requiring remediation at the Site. EPA has also 
determined that the Respondents' activities have not contributed any 
copper loading to the waters at or emanating from the Site.
    12. The material allegedly generated and disposed of by the 
Respondents therefore involves only a minuscule portion of the total 
hazardous substances generated or disposed of at the Site. EPA has also 
concluded that the hazardous substances allegedly contributed to the 
Site by Respondents are not significantly more toxic or of 
significantly greater hazardous effect than other hazardous substances 
at the Site.
    13. EPA estimates that the total response costs incurred and to be 
incurred at or in connection with the Site by the EPA Hazardous 
Substance Superfund will be $152 million. EPA has determined that the 
amount of waste which may have been contributed to the Site by the 
Respondents is so minor that it would be inequitable to require them to 
help finance or perform cleanup at the Site.

V. Determination

    14. Based upon the Statement of Facts set forth above and on the 
information currently known to the United States, EPA has determined 
that:
    (1) The Site is a ``facility'' as that term is defined in Section 
101(9) of CERCLA, 42 U.S.C. 9601(9).
    (2) Each of the Respondents is a ``person'' as that term is defined 
in Section 101(21) of CERCLA, 42 U.S.C. 9601(21).
    (3) Each of the Respondents may be a ``potentially responsible 
party'' within the meaning of Section 122(g)(1) of CERCLA, 42 U.S.C. 
9622(g)(1).
    (4) There has been an actual or threatened ``release'' of a 
``hazardous substance'' from the Site as those terms are defined in 
Sections 101 (22) and (14) of CERCLA, 42 U.S.C. 9601 (22) and (14).
    (5) The amount of hazardous substances contributed to the Site by 
the Respondents and the toxic or other hazardous effects of the 
hazardous substances contributed to the Site by the Respondents are 
minuscule in comparison to other hazardous substances at the Site 
within the meaning of Section 122(g)(1)(A) of CERCLA, 42 U.S.C. 
9622(g)(1)(A).
    (6) Respondents are eligible for a de micromis settlement because 
they have contributed no more than a minuscule amount of hazardous 
substance, if any, to the Site.
    (7) The terms of this Consent Order are consistent with EPA policy 
and guidance for settlements with de micromis waste contributors, 
including but not limited to, ``Revised Guidance on CERCLA Settlements 
with De Micromis Waste Contribution,'' OSWER Directive #9834.17 (June 
3, 1996).
    (8) Prompt final settlement with the Respondents is practicable and 
in the public interest within the meaning of Section 122(g)(1) of 
CERCLA, 42 U.S.C. 9622(g)(1).
    (9) The settlement of this case without litigation and without the 
admission or adjudication of any issue of fact or law is the most 
appropriate means of resolving any liability that the Respondents may 
have for response actions and response costs with respect

[[Page 62598]]

to all releases or threatened releases at or in connection with the 
Site.

VI. Order

    15. Based upon the Information currently known to the United States 
and the Statement of Facts and Determinations set forth above, and in 
consideration of the promises and covenants set forth herein, the 
following is hereby Agreed to and Ordered;

VII. Parties Bound

    16. This Consent Order shall apply to and be binding upon EPA and 
upon Respondents and their successors and assigns. Any change in

    b. The United States' covenant not to sue extends to Respondents 
and to their affiliates, successors and assigns, but only to the extent 
that the liability of such affiliates, successors and assigns is 
derivative of Respondents' liability for those acts set forth in 
Paragraph 9, Section IV of this Order. The United States' covenant not 
to sue does not extend to any other person.

X. Reservation of Rights

    19. The covenant not to sue by the United States set forth in 
Paragraph 18 of this Order does not pertain to any matters other than 
those expressly specified in Paragraph 18. The United States reserves, 
and this Order is without prejudice to, all rights against the 
Respondents with respect to all other matters, including but not 
limited to the following:

(a) criminal liability;
(b) any liability against Respondents that results from their future 
disposal activities at the Site; or
(c) liability for damages for injury to, destruction of, or loss of 
natural resources, including any cost of assessing the injury to, 
destruction of, or loss of such natural resources.

    20. Notwithstanding any other provision in this Consent Order, the 
United States reserves, and this Consent Order is without prejudice to, 
the right to institute judicial or administrative proceedings against 
the Respondents seeking to compel Respondents to perform response 
actions at the Site and/or to reimburse the United States for response 
costs if New Information is discovered that the Respondents no longer 
qualify for a de micromis settlement under the criteria stated in 
Paragraphs 10-12 of this Order.
    21. For purposes of Paragraph 20, ``New Information'' shall not 
include any recalculation of the total volume of waste rock, tailings 
or mine waste containing hazardous substances requiring remediation at 
the Site based solely on Information currently known to the United 
States.

XI. Covenant Not To Sue By Respondents

    22. The Respondents covenant not to sue and agree not to assert any 
claims or causes of action against the United States, or its 
contractors or employees with respect to the Site or this Order, 
including, but not limited to:

IV. Statement of Facts

EPA's Response Actions and Costs

    4. The United States Environmental Protection Agency (EPA) 
initiated removal response actions at the Site on December 18, 1992 to 
address releases or threatened releases of hazardous substances into 
the Alamosa River and surrounding environment pursuant to the 
President's authority under Sections 104 and 106 of the Comprehensive 
Environmental Response, Compensation, and Liability Act of 1980, as 
amended by the Superfund Amendments and Reauthorization Act of 1986, 
Pub. L. 99-499, 42 U.S.C. 9604 and 9606(a) (CERCLA).
    5. On May 31, 1994, EPA listed the Site on the National Priorities 
List as a result of releases or threatened releases of hazardous 
substances at or from the Site.
    6. On December 15, 1994, EPA issued 4 Interim Records of Decision 
selecting the interim remedial actions to be implemented for the 
following activities and/or areas at the Summitville Mine Site: Water 
Treatment (WT IROD), Reclamation, the Heap Leach Pad (HLP IROD) and the 
Cropsy Waste Pile, Beaver Mud Dump/Summitville Dam Impoundment, and 
Mine Pits (CWP IROD).
    7. As of March 31, 1997, the United States had incurred 
approximately $109 million in response costs responding to the release 
or threatened release of hazardous substances at or in connection with 
the Site. The United States continues to incur response costs in 
responding to the release or threat of release of hazardous substances 
at or in connection with the Site.

Respondent's Activities and Potential Liability

    8. EPA alleges that the Respondent is liable for reimbursement of 
the United States' response costs pursuant to Section 107 of CERCLA, 42 
U.S.C. 9607.
    9. From mid-1979 until the latter part of 1983, Respondent's 
predecessor-in-interest, Anaconda Minerals Company (Anaconda), 
conducted exploration and related activities at the Site. Due to Site 
access limitations, severe weather and other adverse Site conditions, 
Anaconda's actual on-Site exploration activities were conducted for an 
aggregate period of approximately 17 months, with this period generally 
coinciding with the summer season of each of the years of 1979 through 
1983.
    10. Anaconda's exploration and related activities at the Site, as 
referred to in Paragraph 9 above, consisted of: (1) a core drilling 
program, consisting of the development of 380 drill holes. In 
accordance with the Colorado Mined Land Reclamation Division 
regulations applicable at the time, these surface drill holes were 
properly plugged with cement and abandoned; (2) limited access to and 
exploration of certain underground mine workings, including the Science 
Mine, Copper Hill Mine, Dexter Mine, Esmond Mine and Chandler Mine, for 
the purpose of mapping and sampling these workings only; (3) related 
on-Site activities such as access road maintenance and road 
construction; and (4) implementation of a hazard elimination program at 
the Site, including tailings dam stabilization work.
    11. Based on Anaconda's findings from these limited exploration and 
related activities, Anaconda determined it would not be profitable to 
initiate mining operations at the Site. Accordingly, Anaconda 
terminated or assigned its leasehold interest in the Site in early 
1984, without conducting any ore extraction or physical mine 
development activities.
    12. Anaconda's surface drilling activities resulted in the 
generation of, at most, 363 cubic yards of waste rock, which may have 
remained on-Site. Waste rock extracted at the Site was mixed with 
cement and used to properly plug and close the drill holes, accordance 
with the Colorado Mined Land Reclamation Division regulations 
applicable at the time. Summitville Consolidated Mining Company Inc. 
subsequently mined, milled, processed or otherwise disturbed this same 
waste rock as a result of its unrelated mining operations.

De Minimis Eligibility

    13. The total volume of waste rock, tailings and other mine waste 
(including the Heap Leach Pad) requiring remediation at the Site is 
approximately 11 million yds.\3\ Four million, five hundred thousand 
cubic yards of this material is being remediated pursuant to the CWP 
IROD; 6.5 million cubic yards are being remediated pursuant to the HLP 
IROD.
    14. According to the WT IROD, approximately 321,000 pounds of 
copper per year, if left untreated, would contaminate the receiving 
waters surrounding the Site, including the Wightman Fork and Alamosa 
River.
    15. EPA has determined parties are eligible for a de minimis 
settlement if their contribution of mine waste and metals loading is 
equal to or less than 3% of the total volume of hazardous substances 
contributed to each of these media.
    16. EPA has determined that the Respondent's contribution of 
hazardous substances to each of these media is below the 3% de minimis 
cut-off established by EPA for the Site.
    17. Based on Information currently known to the United States, EPA 
has calculated the Respondent's de minimis eligibility as follows: (1) 
assuming all waste rock, approximately 363 cubic yards, generated by 
Anaconda during its drilling program remained on-Site, EPA has 
estimated that the amount of hazardous substances allegedly contributed 
to the Site by Respondent

[[Page 62601]]

constitutes approximately .0033% of the total volume of waste rock, 
tailings or mine waste requiring remediation at the Site; and (2) 
because Anaconda's drill holes were properly plugged and it did not 
rehabilitate or otherwise undertake mining operations in adits, tunnels 
or mine workings hydraulically connected to the Reynolds Adit, the 
Respondent's activities have not contributed any copper loading to the 
waters at or emanating from the Site.
    18. As required by Section 122(g)(1) of CERCLA, 42 U.S.C. 
9622(g)(1), EPA has therefore determined that: (A) the amount of 
material allegedly contributed by the Respondent is minimal in 
comparison to the total hazardous substances generated or disposed of 
at the Site; and (B) the toxic or hazardous effect of the hazardous 
substances allegedly contributed to the Site by Respondent are minimal 
in comparison to the other hazardous substances at the Site.
    19. Section 122(g)(1) of CERCLA, 42 U.S.C. 9622(g)(1), further 
authorizes EPA to enter into expedited settlements under Sections 106 
and 107 of CERCLA if such settlements involve only a minor portion of 
the response costs at the facility concerned. EPA estimates that the 
total response costs incurred and to be incurred at or in connection 
with the Site by the EPA Hazardous Substance Superfund will be $152 
million. EPA calculated the settlement amount to be paid by Respondent 
as follows: EPA and Respondent agree that the material generated and 
disposed of by Respondent came to be located in the areas to be 
remediated pursuant to CWP and HLP IRODs. EPA and Respondent estimated 
that of the 363 cubic yards of material generated and disposed of by 
Respondent on the Site, 123 cubic yards came to be located in the area 
to be remediated by the CWP and 240 cubic yards came to be located in 
the HLP. EPA then calculated the appropriate settlement amount by: (a) 
taking the amount it cost to remediate Respondent's volumetric share of 
the CWP; (b) calculating the cost EPA will incur to remediate 
Respondent's volumetric share of the HLP; (c) adding a percentage for 
Respondent's share of Sitewide costs; (d) estimating the enforcement 
costs associated with negotiating and finalizing this AOC; and (e) 
applying a 100% ``premium'' payment to Respondent's share of those 
estimated costs not yet incurred by EPA. In accordance with applicable 
EPA guidance, this 100% ``premium'' payment on estimated costs to be 
incurred provides consideration for EPA's granting the Respondent a 
covenant not to sue without the normal remedy cost overrun reopener.
    20. Based on the factors identified in Paragraph 19 above, EPA 
determined that the appropriate amount to settle Respondent's potential 
CERCLA Section 106 and 107 and RCRA Section 7003 liabilities is 
$95,000. The settlement amount required to be paid by the Respondent 
pursuant to this Order therefore represents only a minor portion of the 
response costs to be recovered for the cleanup of the Site.

V. Determinations

    21. Based upon the Statement of Facts set forth above and on the 
Information currently known to the United States, EPA has determined 
that:
    (1) The Site is a ``facility'' as that term is defined in Section 
101(9) of CERCLA, 42 U.S.C. 9601(9).
    (2) The Respondent is a ``person'' as that term is defined in 
Section 101(21) of CERCLA, 42 U.S.C. 9601(21).
    (3) The Respondent is a ``potentially responsible party'' within 
the meaning of Section 122(g)(1) of CERCLA, 42 U.S.C. 9622(g)(1).
    (4) There has been an actual or threatened ``release'' of a 
``hazardous substance'' from the Site as those terms are defined in 
Sections 101 (22) and (14) of CERCLA, 42 U.S.C. 9601 (22) and (14).
    (5) The amount of hazardous substances contributed to the Site by 
the Respondent and the toxic or other hazardous effects of the 
hazardous substances contributed to the Site by the Respondent are 
minimal in comparison to other hazardous substances at the Site within 
the meaning of Section 122(g)(1)(A) of CERCLA, 42 U.S.C. 9622(g)(1)(A).
    (6) As to the Respondent, this Consent Order involves only a minor 
portion of the response costs at the Site within the meaning of Section 
122(g)(1) of CERCLA, 42 U.S.C. 9622(g)(1).
    (7) The terms of this Consent Order are consistent with EPA policy 
and guidance for settlements with de minimis waste contributors, 
including but not limited to, ``Standardizing the De Minimis Premium,'' 
(July 7, 1995), ``Streamlined Approach for Settling with De Minimis 
Waste Contributors under CERCLA Section 122(g)(1)(A),'' OSWER Directive 
No. 9834.7-1D (July 30, 1993), and ``Methodology for Early De Minimis 
Waste Contributor Settlements under CERCLA Section 122(g)(1)(A),'' 
OSWER Directive No. 9834.7-1C (June 2, 1992).
    (8) Prompt settlement with the Respondent is practicable and in the 
public interest within the meaning of Section 122(g)(1) of CERCLA, 42 
U.S.C. 9622(g)(1).
    (9) The settlement of this case without litigation and without the 
admission or adjudication of any issue of fact or law is the most 
appropriate means of resolving any liability that the Respondent may 
have for response actions and response costs with respect to all 
releases or threatened releases at or in connection with the Site.

VI. Order

    22. Based upon the Information currently known to the United States 
and the Statement of Facts and Determinations set forth above, and in 
consideration of the promises and covenants set forth herein, the 
following is hereby Agreed to and Ordered:

VII. Parties Bound

    23. This Consent Order shall apply to and be binding upon EPA and 
upon Respondent and its successors and assigns. Any change in ownership 
or corporate or other legal status of the Respondent including, but not 
limited to, any transfer of assets or real or personal property, shall 
in no way alter such Respondent's responsibilities under this Consent 
Order. Each signatory to this Consent Order certifies that he or she is 
authorized to enter into the terms and conditions of this Consent Order 
and to execute and bind legally the party represented by him or her.

VIII. Payment

    24. Within 10 days of the effective date of this Order, Respondents 
shall pay a total of $95,000 to the Hazardous Substance Superfund as 
provided below.
    25. Payment shall be made by cashier's check made payable to ``EPA 
Hazardous Substance Superfund.'' The check shall reference the Site 
name, the name and address of the Respondent, EPA CERCLA Number 08-Y3 
and DOJ Case No. 90-11-3-1133A and shall be sent to: Mellon Bank, EPA 
Region VIII, Attn: Superfund Accounting, P.O. Box 360859M, Pittsburgh, 
PA 15251.
    26. If the Respondent fails to make full payment within the time 
required by Paragraph 25, Respondent shall pay Interest on the unpaid 
balance. In addition, if Respondent fails to make full payment as 
required by Paragraph 25, the United States may, in addition to any 
other available remedies or sanctions, bring an action against the 
Respondent seeking injunctive relief to compel payment and/or seeking 
civil penalties under Section 122(l) of CERCLA, 42 U.S.C. 9622(l), for 
failure to make timely payment.

[[Page 62602]]

    27. The Respondents' payment includes an amount representing the 
Respondent's fair share of: (a) past response costs incurred at or in 
connection with the Site; (b) projected future response costs to be 
incurred at or in connection with the Site; and (c) a significant 
premium to cover the risks 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, will exceed the estimated 
total response costs upon which Respondent's payment is based.
    28. Payments made under this Section may be placed in a site-

IV. Statement of Facts

    4. The United States Environmental Protection Agency (EPA) 
initiated removal response actions at the Site on December 18, 1992 to 
address releases or threatened releases of hazardous substances into 
the Alamosa River and surrounding environment pursuant to the 
President's authority under Sections 104 and 106 of the Comprehensive 
Environmental Response, Compensation and Liability Act of 1980, as 
amended by the Superfund Amendments and Reauthorization Act of 1986, 
Pub. L. 99-499, 42 U.S.C. 9604 and 9606(a) (CERCLA).
    5. On May 31, 1994, EPA listed the Site on the National Priorities 
List as a result of releases or threatened releases of hazardous 
substances at or from the Site.
    6. On December 15, 1994, EPA issued 4 Interim Records of Decision 
selecting the interim remedial actions to be implemented for the 
following activities and/or areas at the Summitville Mine Site: Water 
Treatment (WT IROD), Reclamation, the Heap Leach Pad (HLP IROD) and the 
Cropsy Waste Pile, Beaver Mud Dump/Summitville Dam Impoundment, and 
Mine Pits (CWP IROD).
    7. As of March 31, 1997, the United States incurred approximately 
$109 million in response costs responding to the release or threatened 
release of hazardous substances at or in connection with the Site. The 
United States continues to incur response costs in responding to the 
release or threat of release of hazardous substances at or in 
connection with the Site.
    8. EPA alleges that the Respondent is liable for reimbursement of 
the United States' response costs pursuant to Section 107 of CERCLA, 42 
U.S.C. 9607.
    9. Respondent conducted sporadic exploration and related activities 
from 1974 through 1980 under a lease that expired in 1981. ASARCO's 
exploration program consisted of a systematic program of percussion and 
diamond core drilling, aimed at determining the ore reserves and the 
viability of conducting mining operations at the Site. First, ASARCO 
drilled 2 deep holes, to depths of 3,000 and 4,700 feet, respectively, 
to test its theory that a large porphyry-type copper deposit was 
present at the Site. In 1975, ASARCO drilled 396 shallow holes and 14 
deep holes as part of this drilling program. ASARCO also conducted 
backhoe trenching as part of its exploration program to generally 
define the boundaries of outcrops and underground mineral deposits. It 
is estimated that approximately 31 tons of material was generated from 
ASARCO's drilling program, some or all of which is believed to have 
been removed from the Site for sampling and analysis.
    10. ASARCO dug 49 trenches amounting to 15,213 linear feet, with an 
average depth of 6 feet. The procedure for sampling these trenches was 
to collect approximately \1/2\ pound per linear foot of trench. This 
sampling effort would have amounted in 2.9 tons of waste material 
disturbed by ASARCO remaining on-site. The trenches were backfilled and 
revegetated in accordance with contemporary mining practices and 
Colorado Mined Land Reclamation Board requirements.

[[Page 62605]]

    11. ASARCO also evaluated several adits, including the Copper Hill, 
Del Norte, Upper Highland Mary, Esmond, Science, Narrow Gauge, Aztec, 
Old Pickens, Chandler, Iowa and French adits. A total of 3,915 feet was 
cleared of ice and mapped and 2,110 feet of these adits was sampled and 
assayed by ASARCO. The adit rehabilitation program was abandoned, 
without ASARCO either retimbering or otherwise conducting any 
rehabilitation activities.
    12. As of August 1976, ASARCO also abandoned its plan to dewater 
and rehabilitate the Missionary Shaft or its underworkings. ASARCO did 
not conduct any rehabilitation or mining activities at the Missionary 
Shaft or its associated underworkings.
    13. Based on the data available to the Parties, EPA and Respondent 
estimate that the amount of material generated as a result of ASARCO's 
limited exploration activities amounts to approximately 31 tons or 25 
yds.\3\ EPA and ASARCO also agree that its limited diamond drilling 
program may have disturbed approximately 0.14 acre of the surface of 
the Site. EPA and ASARCO also agree that the actual amount of time 
ASARCO conducted its exploration activities lasted a total of 
approximately 16 months.
    14. On July 1, 1987, Hydrometrics, Inc. became a wholly-owned 
subsidiary of ASARCO. As documented in ASARCO's CERCLA Section 104(e) 
information request response, Hydrometrics, Inc. performed certain 
testing, sampling and data compilation functions as a contractor or 
consultant to Galactic Resources, Ltd. or its wholly-owned 
subsidiaries, including Galactic Resources, Inc., Galactic Services, 
Inc. or Summitville Consolidated Mining Company, Inc. There is no 
indication, however, that any of Hydrometrics' activities resulted in 
the generation or disposal of any waste materials on-site.
    15. The total volume of waste rock, tailings and other mine waste 
(including the Heap Leach Pad) requiring remediation at the Site is 
approximately 11 million yds.\3\ According to the WT IROD, 
approximately 321,000 pounds of copper per year, if left untreated, 
would contaminate the receiving waters surrounding the Site, including 
the Wightman Fork and Alamosa River. EPA has determined parties are 
eligible for a de minimis settlement if their contribution of mine 
waste and metals loading is equal to or less than 3% of the total 
volume of hazardous substances contributed to each of these media. The 
Respondent's contribution of hazardous substances to these media are 
below the 3% de minimis cut-off established by EPA for the Site.
    16. Based on Information currently known to the United States, EPA 
has calculated the Respondent's de minimis eligibility as follows: EPA 
has estimated that the amount of hazardous substances allegedly 
contributed to the Site by Respondents constitutes substantially less 
than 1% of the total volume of waste rock, tailings or mine waste 
requiring remediation at the Site. EPA has also determined that the 
Respondent's activities have not contributed any copper loading to the 
waters at or emanating from the Site.
    17. The material allegedly generated and disposed of by the 
Respondent therefore involves only a minor portion of the total 
hazardous substances generated or disposed of at the Site. EPA has also 
concluded that the hazardous substances allegedly contributed to the 
Site by Respondent are not significantly more toxic or of significantly 
greater hazardous effect than other hazardous substances at the Site.
    18. EPA estimates that the total response costs incurred and to be 
incurred at or in connection with the Site by the EPA Hazardous 
Substance Superfund will be $152 million. The payment required to be 
made by the Respondent pursuant to this Order represents only a minor 
portion of the response costs to be recovered for the cleanup of the 
Site.

V. Determinations

    19. Based upon the Statement of Facts set forth above and on the 
Information currently known to the United States, EPA has determined 
that:
    (1) The Site is a ``facility'' as that term is defined in Section 
101(9) of CERCLA, 42 U.S.C. 9601(9).
    (2) The Respondent is a ``person'' as that term is defined in 
Section 101(21) of CERCLA, 42 U.S.C. 9601(21).
    (3) The Respondent is a ``potentially responsible party'' within 
the meaning of Section 122(g)(1) of CERCLA, 42 U.S.C. 9622(g)(1).
    (4) There has been an actual or threatened ``release'' of a 
``hazardous substance'' from the Site as those terms are defined in 
Sections 101 (22) and (14) of CERCLA, 42 U.S.C. 9601 (22) and (14).
    (5) The amount of hazardous substances contributed to the Site by 
the Respondent and the toxic or other hazardous effects of the 
hazardous substances contributed to the Site by the Respondent are 
minimal in comparison to other hazardous substances at the Site within 
the meaning of Section 122(g)(1)(A) of CERCLA, 42 U.S.C. 9622(g)(1)(A).
    (6) As to the Respondent, this Consent Order involves only a minor 
portion of the response costs at the Site within the meaning of Section 
122(g)(1) of CERCLA, 42 U.S.C. 9622(g)(1).
    (7) The terms of this Consent Order are consistent with EPA policy 
and guidance for settlements with de minimis waste contributors, 
including but not limited to, ``Standardizing the De Minimis Premium,'' 
(July 7, 1995), ``Streamlined Approach for Settling with De Minimis 
Waste Contributors under CERCLA Section 122(g)(1)(A),'' OSWER Directive 
No. 9834.7-1D (July 30, 1993), and ``Methodology for Early De Minimis 
Waste Contributor Settlements under CERCLA Section 122(g)(1)(A),'' 
OSWER Directive No. 9834.7-1C (June 2, 1992).
    (8) Prompt settlement with the Respondent is practicable and in the 
public interest within the meaning of Section 122(g)(1) of CERCLA, 42 
U.S.C. 9622(g)(1).
    (9) The settlement of this case without litigation and without the 
admission or adjudication of any issue of fact or law is the most 
appropriate means of resolving any liability that the Respondent may 
have for response actions and response costs with respect to all 
releases or threatened releases at or in connection with the Site.

VI. Order

    20. Based upon the Information currently known to the United States 
and the Statement of Facts and Determinations set forth above, and in 
consideration of the promises and covenants set forth herein, the 
following is hereby Agreed to and ordered:

VII. Parties Bound

    21. This Consent Order shall apply to and be binding upon EPA and 
upon Respondent and its successors and assigns. Any change in ownership 
or corporate or other legal status of the Respondent including, but not 
limited to, any transfer of assets or real or personal property, shall 
in no way alter such Respondent's responsibilities under this Consent 
Order. Each signatory to this Consent Order certifies that he or she is 
authorized to enter into the terms and conditions of this Consent Order 
and to execute and bind legally the party represented by him or her.

VIII. Payment

    22. Within 10 days of the effective date of this Order, Respondents 
shall pay a total of $86,052.73 to the Hazardous Substance Superfund as

[[Page 62606]]

Hazardous Substance Superfund.'' The check shall reference the Site 
name, the name and address of the Respondent, EPA CERCLA Number 08-Y3 
and DOJ Case No. 90-11-3-1133A and shall be sent to: Mellon Bank, PA 
Region VIII, Attn: Superfund Accounting, P.O. Box 360859M, Pittsburgh, 
PA 15251.
    24. If the Respondent fails to make full payment within the time 
required by Paragraph 22, Respondent shall pay Interest on the unpaid 
balance. In addition, if Respondent fails to make full payment as 
required by Paragraph 22, the United States may, in addition to any 
other available remedies or sanctions, bring an action against the 
Respondent seeking injunctive relief to compel payment and/or seeking 
civil penalties under Section 122(l) of CERCLA, 42 U.S.C. 9622(l), for 
failure to make timely payment.
    25. The Respondent's payment includes an amount representing the 
Respondent's fair share of: (a) past response costs incurred at or in 
connection with the Site; (b) projected future response costs to be 
incurred at or in connection with the Site; and (c) a premium to cover 
the risks associated with this settlement, including but not limited 
to, the risk that total response costs incurred or to be incurred at or

upon which Respondent's payment is based.
    26. Payments made under this Section may be placed in a site-
specific ``special'' or ``reimbursable'' account by EPA. This site-
specific reimbursable account within the EPA Hazardous Substance 
Superfund shall be known as the Summitville Mine Superfund Site Special 
Account and shall be retained and used by EPA to conduct or finance the 
response actions at or in connection with the Site. Upon completion of 
the final remedial action for the Site, any balance remaining in the 
Summitville Mine Superfund Site Special Account shall be transferred by 
EPA to the general EPA Hazardous Substance Superfund.

    30. Notwithstanding any other provision in this Consent Order, the 
United States reserves, and this Consent Order is without prejudice to, 
the right to institute judicial or administrative proceedings against 
the Respondent seeking to compel Respondent to perform response actions 
at the Site and/or to reimburse the United States for additional costs 
of response if New Information is discovered that the Respondent 
contributed: (a) hazardous substances in an amount greater than 1% of 
the total volume of waste rock, tailings or mine waste containing 
hazardous substances requiring remediation at the Site; or (b) 
hazardous substances that contributed to the total copper loading to 
the waters at or emanating from the Site; or (c) hazardous substances 
at the Site which are significantly more toxic or are of significantly 
greater hazardous effect that other hazardous substances at the Site.
    31. For purposes of Paragraph 30, ``New Information'' shall not 
include any recalculation of the total volume of waste rock, tailings 
or mine waste containing hazardous substances requiring remediation at 
the Site based solely on Information currently known to the United 
States.
    32. In the event the United States institutes judicial or 
administrative proceedings against the Respondent pursuant to Paragraph

legal or factual matters set forth in this Order. Further, neither this 
Order, Respondent's consent to this Order, nor Respondent's actions in 
accordance with this Order shall be admissible in evidence against 
Respondent without its consent, except in a proceeding to enforce this 
Order. Respondent does not admit, and retains the right to controvert 
in any subsequent proceedings other than proceedings to implement or
