                               EXPLANATORY NOTE

This Amendment No. 1 (the  "Amendment") to the Annual Report on Form 40-F filed
on March 26, 2007 (the  "Original  Form  40-F") of Teck  Cominco  Limited  (the
"Company")  for the fiscal  year ended  December  31,  2006,  is being filed to
reflect  additional  disclosure on the remedial  investigation  and feasability
study of  contamination  in Lake  Roosevelt  in  Washington  State that we have
disclosed  in  Management's  Discussion  and  Analysis--Legal  Proceedings  and
Consolidated   Financial   Statements--Notes   to  Financial   Statements--Note
22--Commitments and Contingencies--Legal Proceedings and Contingencies in light
of  comments  from the  Staff of the  Securities  and  Exchange  Commission  in
connection with its review of the Original Form 40-F.

UPPER COLUMBIA RIVER

Prior to our  acquisition  in 2000 of a majority  interest in Cominco Ltd. (now
Teck Cominco Metals Ltd.)  ("TCML"),  TCML's Trail smelter  discharged  smelter
slag  into the  Columbia  River.  These  discharges  commenced  prior to TCML's
acquisition  of the Trail  smelter in 1906 and continued  until 1996.  Slag was
discharged  pursuant to permits  issued in British  Columbia  subsequent to the
enactment  of  relevant  environmental  legislation  in 1967.  Slag  and  other
non-slag  materials  released from the Trail  smelter in British  Columbia have
travelled  down  river and mixed  with  substances  discharged  from many other
smelting  and  industrial  facilities  located  along  the  length of the Upper
Columbia River system in Canada and the U.S.

Slag is a glass-like compound consisting primarily of silica, calcium and iron,
which  contains  small  amounts of base metals such as zinc,  lead,  copper and
cadmium.  It is sufficiently  inert that it is not characterized as a hazardous
waste  under  applicable  Canadian  or U.S.  regulations.  While  slag has been
deposited  into the river,  further study is required to assess what effect the
presence  of slag in the river has had, and  whether  it poses an  unacceptable
risk to human health or the  environment.  A large number of studies  regarding
slag  deposition  and its effects have been  conducted by various  governmental
agencies on both sides of the border.  The  historical  studies of which we are
aware have not  identified  unacceptable  risks  resulting from the presence of
slag in the river.

On June 2, 2006,  TCML and its affiliate,  Teck Cominco  American  Incorporated
("TCAI"),  entered into a Settlement  Agreement (the "Agreement") with the U.S.
Environmental  Protection Agency ("EPA") and the United States under which TCAI
is paying for and conducting a remedial  investigation  and  feasibility  study
("RI/FS") of  contamination  in the Upper Columbia River (the "Studies")  under
the  oversight  of  the  EPA.  The  RI/FS  is  being  prepared  by  independent
consultants  approved  by the EPA and  retained by TCAI.  TCAI is paying  EPA's
oversight  costs  and  providing   funding  for  the   participation  of  other
governmental  parties,  the State of  Washington  and two  native  tribes,  the
Confederated  Tribes of the  Colville  Nation (the  "Colville  Tribes") and the
Spokane Tribe.  TCML has guaranteed TCAI's  performance of the Agreement.  TCAI
has  also  placed  US$20  million  in  escrow  as  financial  assurance  of its
obligations  under the  Agreement and we have accrued our estimate of the costs
of the Studies.  Contemporaneously with the execution of the Agreement, the EPA
withdrew a unilateral administrative order ("UAO") purporting to compel TCML to
conduct the Studies.




The RI/FS  process  requires  TCAI to submit a work plan for the  assessment of
site conditions to the EPA which,  when approved,  will lead to the development
of a set of  sampling  and other plans and actual  field work.  Data from field
work will be used to  determine  whether  further  studies are  required.  When
sufficient data have been compiled to adequately  assess risk, a baseline human
health and  environmental  risk assessment  ("RA") will be produced to identify
risks, if any, that may exist to humans and to various environmental receptors.
The RA will form the basis  for the  RI/FS.  The  remedial  investigation  will
identify  potential  remedial  options  available to mitigate any  unacceptable
risks;  the  feasibility  study  will  consider  engineering,   procedural  and
practical  constraints to these remedial  options.  Based on the RI/FS, the EPA
will determine  whether and what remedial actions are appropriate in accordance
with  criteria  that  take  into  account,   among  other  factors,   technical
feasibility, effectiveness, cost, effects on the environment resulting from the
remedial  action,  and  acceptability  of the relevant  remedial  option to the
community.  Each  work  product  and plan in this  process  is  subject  to EPA
approval.  Internal consultation processes of the EPA will include consultation
with state and other federal  agencies and the two Indian Tribes  bordering the
site, the Coville Tribe and the Spokane Tribe.

While the UAO was outstanding,  two citizens of Washington State and members of
the Colville Tribe commenced an enforcement  proceeding under Section 310(a)(i)
of the  Comprehensive  Environmental  Response,  Compensation and Liability Act
("CERCLA") to enforce the UAO and to seek fines and penalties  against TCML for
non-compliance.  TCML sought to have all claims dismissed on the basis that the
court lacked jurisdiction because the CERCLA statute was not intended to govern
the  discharges  of a  facility  occurring  in another  country.  That case has
proceeded  through U.S. Federal District Court and the Federal Court of Appeals
for the 9th  Circuit.  The 9th Circuit  affirmed the  District  Court  decision
denying TCML's motion to dismiss the case on  jurisdictional  grounds and found
that CERCLA could be applied to TCML's disposal  practices in British  Columbia
because they may have had an effect in  Washington  State.  The 9th Circuit has
issued a stay of its decision  pending the  resolution  of a further  appeal by
TCML to the U.S. Supreme Court.

On February  27, 2007,  TCML filed a petition for review and reversal  with the
U.S.  Supreme  Court.  TCML's  petition was supported by amicus briefs filed by
Canada, the Province of British Columbia, the Mining Association of Canada, the
U.S. National Mining Association,  the U.S.  Association of Manufacturers,  the
Canadian  and  U.S.   Chambers  of  Commerce   and  the  Consumer   Electronics
Association.

On June 4, 2007, the U.S.  Supreme Court requested the Solicitor  General opine
on the  petition  for review on behalf of the  Administration.  There can be no
assurance  that the U.S.  Supreme  Court  will agree to hear  TCML's  appeal or
reverse the decision or that the  withdrawal  of the UAO and the  settlement of
the  Agreement  will be  sufficient  to resolve  the matter or that TCML or its
affiliates will not be faced with further liability in relation to this matter.
Until the  studies  contemplated  by the  Agreement  are  completed,  it is not
possible to estimate the extent and cost, if any, of remediation or restoration
that may be required.  The studies may  conclude,  on the basis of risk,  cost,
technical   feasibility  or  other  grounds,  that  no  remediation  should  be
undertaken.  If  remediation  is  required,  the  cost  of  remediation  may be
material.
