                                 PROXY STATEMENT
                         ANNUAL MEETING OF STOCKHOLDERS
                                 --------------

This proxy statement is furnished in connection with the solicitation of proxies
by the Board of Directors (the "Board") of Oregon Steel Mills, Inc. (the
"Corporation") to be voted at the Annual Meeting of Stockholders to be held in
the Cambridge/Oxford Room at the Benson Hotel, 309 SW Broadway, Portland,
Oregon, on Thursday, April 29, 2004, at 8:00 a.m. Pacific Time, and any
adjournments thereof.

Only stockholders of record at the close of business on March 8, 2004, are
entitled to notice of, and to vote at, the meeting. At the close of business on
that date, the Corporation had 26,495,172 shares of Common Stock, $0.01 par
value per share ("Common Stock"), outstanding. Holders of Common Stock are
entitled to one vote for each share of Common Stock held. There are no
cumulative voting rights.

When a proxy in the form accompanying this proxy statement is properly executed
and returned, the shares represented will be voted at the meeting in accordance
with the instructions specified in the proxy. If no instructions are specified,
the shares will be voted FOR Proposal 1 and AGAINST Proposal 2 in the
accompanying Notice of Annual Meeting of Stockholders, and such votes will be
counted toward determining a quorum. Shares held of record by the Trustees of
the Corporation's Employee Stock Ownership Plan Trust (the "ESOP") will be voted
by the Trustees in accordance with instructions received from ESOP participants
or, if no such instructions are received, the Trustees shall vote or take other
action as they deem appropriate. Any person giving a proxy in the form
accompanying this proxy statement has the power to revoke it at any time before
its exercise. A stockholder may revoke a proxy by (i) written notice of such
revocation to the Secretary of the Corporation at the above address; (ii) a
later-dated proxy received by the Corporation; or (iii) attending the meeting
and voting in person. Attendance at the meeting will not by itself revoke a
proxy.

Each share of Common Stock outstanding on the record date is entitled to one
vote per share at the Annual Meeting of Stockholders. Shares of Common Stock
represented in person or by proxy at the Annual Meeting (including abstentions
and broker non-votes) will be tabulated by the inspector of election appointed
for the meeting and will be counted in determining that a quorum is present. For
Proposal 1, (i) the nominees receiving a plurality of the votes cast at the
Annual Meeting are elected as directors; (ii) withholding authority to vote for
a director will be treated as a vote cast against the nominee; and (iii) a
broker non-vote will not be treated as a vote cast.

For Proposal 2, an abstention will have the effect as a vote against Proposal 2
and a broker non-vote will have no effect in determining whether the stockholder
proposal was approved.

The approximate date on which this proxy statement and the accompanying proxy
card are being mailed to the Corporation's stockholders is March 29, 2004.
Solicitation material will be furnished to brokerage houses, fiduciaries, and
custodians holding shares in their names that are beneficially owned by others
to forward to such beneficial owners. Original solicitation of proxies by mail
may be supplemented by one or more telephone, telegram or personal solicitations
by directors, officers, or employees of the Corporation. No additional
compensation will be paid for any such services. Except as described above, the
Corporation does not intend to solicit proxies other than by mail. Costs of
solicitation will be borne by the Corporation.







            PROPOSAL 1: NOMINATION AND ELECTION OF CLASS A DIRECTORS
--------------------------------------------------------------------------------
NOMINEES

The Corporation has a classified Board consisting of two Class A directors,
Messrs. Parkinson, and Sproul; three Class B directors, Messrs. Demorest,
Reynolds, and Swindells; and three Class C directors, Messrs. Declusin, Neun,
and Walker. Class B and C directors serve until the Annual Meetings of
Stockholders to be held in 2005 and 2006, respectively, and until their
successors are elected and qualified. At each Annual Meeting of Stockholders,
directors are elected for a term of three years to succeed those directors whose
terms expire at that annual meeting.

The nominees for election as Class A directors are William Kinnune, David
Parkinson, and Brett Wilcox. Mr. Parkinson is a member of the present Board.
Messrs. Kinnune and Wilcox are new nominees and were recommended to the
Nominating/Corporate Governance and Compensation Committee for nomination by
non-management directors. Each of the nominees has consented to serve if
elected. The Corporation does not pay a fee to any third party to identify or
evaluate or assist in identifying or evaluating potential nominees. The Class A
directors to be elected at the 2004 Annual Meeting will serve until the Annual
Meeting of Stockholders in 2007 and until their successors are elected and
qualified.

Mr. Sproul who has served as a director since 1989 will retire from the Board
effective as of the Annual Meeting. The Board has adopted a resolution,
effective as of the Annual Meeting, to increase the size of the Board to nine
members and the number of Class A directors to three.

Unless authority to vote for a director is withheld, the accompanying proxy, if
properly executed and returned, will be voted for the election of the Class A
nominees named below. If authority to vote for the nominees is withheld, the
withheld votes will not be cast for any other nominee. If any nominee is unable
or unwilling to serve as a director, proxies may be voted for such substitute
nominee as may be designated by the Board. The Board has no reason to believe
that any nominee will be unable or unwilling to serve as a director if elected.

The following table sets forth information with respect to the persons nominated
for election as Class A directors and each other director, including their names
and ages as of February 27, 2004, business experience during the past five
years, and directorships in other corporations.

                    THE BOARD OF DIRECTORS AND ITS COMMITTEES
--------------------------------------------------------------------------------
The Board has standing Executive, Audit, and Nominating/Corporate Governance and
Compensation Committees.

EXECUTIVE COMMITTEE.

The Executive Committee may exercise all the authority of the Board, subject to
the actions of the full Board and except as otherwise provided by the
Corporation's restated certificate of incorporation, the Corporation's bylaws or
applicable law. The members of the Executive Committee during January 2003
through July 2003 were Messrs. Corvin, Demorest and Reynolds and during August
2003 through December 2003 were Messrs. Declusin, Demorest and Reynolds. Mr.
Swindells as Chairman of the Board is an ex officio member of each Committee.

AUDIT COMMITTEE.

The Audit Committee's purpose is to assist Board oversight of: (i) the integrity
of the Corporation's financial statements, (ii) the Corporation's compliance
with legal and regulatory requirements, (iii) the independence and qualification
of the outside auditors and (iv) the performance of the Corporation's internal
audit function and outside auditor. The members of the Audit Committee during
2003 were Messrs. Demorest, Neun, Parkinson, and Sproul.

NOMINATING/CORPORATE GOVERNANCE AND COMPENSATION COMMITTEE.

In 2002, the functions of the Nominating Committee and Compensation Committee
were combined into the Nominating/Corporate Governance and Compensation
("Nominating/Compensation") Committee. The members of the
Nominating/Compensation Committee during January 2003 through July 2003 were
Messrs. Reynolds, Declusin and Walker, from August 2003 through December 2003
were Messrs. Reynolds, Swindells and Walker. The Board has determined that each
member of the Nominating/Compensation Committee is independent, as independence
is defined in the New York Stock Exchange listing standards. In 2004, the
Corporation adopted a Nominating and Compensation Committee charter, which is
attached as Appendix A and is also available on the Corporation's website at
www.osm.com.
-----------

[BULLET] NOMINATING/CORPORATE GOVERNANCE.
         The purposes of this Committee in the areas of Nominating/Corporate
         Governance are to (i) identify individuals qualified to become Board
         members, consistent with criteria approved by the Board, and to select
         or to recommend that the Board select, the director nominees for the
         next annual meeting of stockholders, (ii) develop and recommend to the
         Board a set of corporate governance principles applicable to the
         Corporation and (iii) oversee the evaluation of the Board and
         Corporation management.

         The Nominating/Compensation Committee will, with direct input from the
         Chairman and CEO, identify qualified individuals to become directors,
         and make recommendations to the full Board for approval. It is expected
         that all directors will be alert to potential board candidates with
         appropriate skills and characteristics and communicate such information
         to the Committee. The Committee will consider stockholder suggestions
         as to nominees for directors, such suggestions should be addressed to
         the Secretary of the Corporation at its principal executive offices and
         contain the information required by Section 1.2 of the Corporation's
         bylaws. The information required includes the name, age, business
         address and residence address of the proposed nominee, the principal
         occupation or employment of the proposed nominee, the number of shares
         of the Corporation held by the proposed nominee, any other information
         required by the SEC rules to be disclosed in a proxy statement and a
         written consent of the proposed nominee to being named as a nominee and
         to serve as a director if elected. In addition, the proposing
         stockholder must provide such stockholder's name and address, the
         number of shares of the Corporation held by the stockholder, a
         description of any arrangement between the proposed nominee and the
         stockholder, confirm that the stockholder will appear at the meeting to
         nominate the proposed nominee and any other information required by the
         SEC rules to be disclosed in a proxy statement. In 2004, the
         Corporation adopted Corporate Governance Guidelines that specify that
         the Board seeks directors from diverse professional backgrounds who
         combine a broad spectrum of experience and expertise with a reputation
         of integrity and are selected based upon contributions such nominees
         can make to the Board and management. In addition, any nominee should
         have experience in positions with a high degree of responsibility, be a
         leader in the organization with which the nominee is affiliated,
         understand the Corporation's business environment and be free from
         relationships or conflicts of interest that could interfere with the
         director's duties to the Corporation and its stockholders. The nominee
         must be willing to devote sufficient time to carrying out the
         director's duties and responsibilities effectively and should be
         committed to serve on the board for an extended period of time. The
         Committee may also develop and recommend to the Board additional
         criteria for selecting new directors, including background, skills,
         experience, age, diversity, time availability (including the number of
         other boards the person sits on), needs of the Board and current and
         further business directions of the Corporation. Although the Committee
         has not adopted specific criteria, any proposed

                                      -4-



         nominees must meet the qualifications set forth in the Corporate
         Governance Guidelines and additional criteria, when adopted. Assuming
         compliance with the procedures, there would be no differences in the
         evaluation of a proposed nominee if the proposed nominee is recommend
         by a stockholder. The Corporation received no notice of a director
         candidate recommended by a stockholder or group with 120 days before
         the anniversary of the prior year's release of the proxy statement.

         In order to be considered for the 2005 Annual Meeting of Stockholders,
         such suggestions should be received by no later than November 30, 2004.

[BULLET] COMPENSATION.
         The purposes of the Committee in the areas of compensation are to have
         direct responsibility to (i) review and approve corporate goals and
         objectives relevant to CEO compensation, evaluate the CEO's performance
         in light of those goals and objectives, and either as a committee or
         together with the other independent directors (as directed by the
         Board), determine and approve the CEO's compensation based on this
         examination; (ii) make recommendations to the Board with respect to
         non-CEO compensation, incentive compensation plans and equity-based
         plans; and (iii) produce an annual report on executive compensation as
         required by the SEC for inclusion in the proxy statement or Form 10-K.

MEETINGS.

During 2003, the Board held 6 meetings, the Audit Committee held 5 meetings, and
the Nominating/Compensation Committee held 5 meetings. Each incumbent director
attended at least 75% of the aggregate number of Board meetings and meetings of
committees of which he is a member which were held during the period for which
he was a director.

EXECUTIVE SESSIONS.

The Board meets in executive session without management at the conclusion of
each regular Board meeting. Mr. Swindells as chairman of the Board was selected
to preside at the executive sessions of non-management directors.

COMMUNICATIONS WITH NON-MANAGEMENT DIRECTORS.

Anyone who has a concern about the Corporation's conduct, accounting, internal
accounting controls or auditing matters may communicate that concern directly to
the non-management directors, or to the Audit Committee. Concerns may be
submitted confidentially or anonymously. Submissions may be emailed, submitted
in writing, or reported by phone to a toll-free phone number - 1-800-826-6762.
This contact information is published on the Corporation's website, www.osm.com.
Submissions for non-management directors will be reviewed by the presiding
director of the non-management directors, Mr. Swindells and submissions for the
Audit Committee will be reviewed by the chair of the Audit Committee, Mr.
Demorest.

GOVERNANCE DOCUMENTS AND DIRECTORS' POLICIES.

The Corporation has adopted Corporate Governance Guidelines, a Code of Business
Conduct and Ethics, Codes of Ethics for the Chief Executive Officer and Senior
Financial Professionals, Audit Committee Charter and Nominating/Compensation
Committee Charter. Each of these documents is available on the Corporation's
website, www.osm.com, and the information is available in print to any
stockholder who requests it. In addition to these guidelines, codes and
charters, and the Corporation's bylaws and certificate of incorporation, the
Board's policy is that all directors should attend the Annual Meeting and in
2003, all directors attended the Annual Meeting.

OTHER RELATIONSHIPS

Oregon Feralloy Partners is a joint venture between Feralloy Corporation
("Feralloy") and the Corporation that processes plate from hot roll coil product
produced by the Corporation. Feralloy is the operating partner and owns 40% and
the Corporation owns 60% and leases certain real property in Portland, Oregon.
During 2003, plate processing transactions amounted to approximately $5.4
million. Mr. Walker is the President and Chief Executive Officer of Feralloy.

INDEPENDENCE

In January 2004, the Board affirmatively determined that each of the current
directors, except Mr. Declusin, is "independent" as required by the New York
Stock Exchange listing standards. In making that determination, the Board
concluded that except for Messrs. Walker and Declusin, the other directors had
no relationships with the Corporation (either directly or indirectly as a
partner, stockholder or officer of an organization that has a relationship with
the Corporation) except as a director. With respect to Mr. Walker, the Board
separately determined that Mr. Walker was independent finding that Mr. Walker's
and Feralloy's relationship with the Corporation was not material. The bases of
that determination were (i) the relationship did not fall within any of the
disqualification provisions specified by the New York Stock Exchange listing
standards; (ii) the relationship between the Corporation and Ferralloy is not
material in the Board's opinion in that it represents less than 1% of the
Cor-

                                      -5-



poration's business and less than 2% of Ferralloy's business; and (iii)
except for the Oregon Feralloy Partners ~relationship, there were no other
material relationships between Mr. Walker and the Corporation, including
commercial, industrial, banking, consulting, legal, accounting, charitable, and
familial.



                            COMPENSATION OF DIRECTORS
--------------------------------------------------------------------------------
Directors who are not full-time employees of the Corporation receive an annual
fee of $21,000, plus $1,200 for each Board and committee meeting attended and
reimbursement of expenses. Directors who are full-time employees of the
Corporation do not receive fees for serving on the Board or on committees.

The Board established, effective April 26, 2002, the Non-Employee Directors'
Stock Option Plan (the "Directors' Stock Option Plan"). The Directors' Stock
Option Plan provides for outside directors to receive initial grants of options
to purchase 4,000 shares of common stock on the effective date and annual grants
of options to purchase 1,500 shares of the common stock on the day of the annual
meeting, at an exercise price equal to the closing price on the grant date, and
vesting over three years. New directors receive an initial grant of options to
purchase 2,000 shares on the day after their appointment. On May 1, 2003, each
non-employee director received annual grants of options to purchase 1,500
shares.

The Board terminated the Oregon Steel Mills, Inc. Directors' Retirement Plan
(the "Retirement Plan") as of December 31, 2001. Under the Retirement Plan, in
effect since January 1, 1998, retiring directors who had completed five years of
service as an outside director were paid $20,000 annually until the number of
payments equals the number of full years of service as an outside director. The
payment terms were convertible to a lump-sum present value payment if so elected
by the retiring director and approved by the Compensation Committee.

In terminating the Retirement Plan, terms of payment of vested benefits were
arranged for the two current outside directors with more than five years of
service on the Board. Beginning in January 2002, Mr. John A. Sproul, who began
as an outside director in 1989, will receive six annual payments of $34,505, and
Mr. William Swindells, an outside director since 1994, will receive six annual
payments of $22,752.

                        OPTION GRANTS DURING FISCAL 2003

In April 2000, the stockholders approved the Corporation's 2000 Long-Term
Incentive Nonqualified Stock Option Plan ("Option Plan"). The Option Plan is
administered by the Compensation Committee of the Board of Directors and
provides for grants to officers and employees of options to acquire up to one
million shares of the Common Stock, subject to the limitations set forth in the
Option Plan. Pursuant to the Option Plan, the granting of options is at the
discretion of the Board of Directors, and it has the authority to set the terms
and conditions of the options granted. No options were granted under the plan in
2003. As of February 16, 2004, options to purchase 451,116 shares of the Common
Stock were outstanding under the Option Plan.

                        DEFINED BENEFIT RETIREMENT PLANS

The Corporation's pension plans are defined benefit plans qualified under
section 401(a) of the Internal Revenue Code (the "Code"). Executive officers and
most other domestic employees of the Corporation are eligible to participate in
the Oregon Steel Mills, Inc. Pension Plan (the "Plan") or similar plans. Normal
retirement is at age 65.

The amount of an employee's pension benefit and the resulting monthly payments
an employee receives upon retirement are based upon the level of the employee's
prior annual compensation, the employee's number of years of benefit service,
and other factors. The employee's annual pension benefit is equal to the sum of:

      (i) for each full or partial year of benefit service prior to January 1,
        1994, 1% of the first $22,800 of Past Service Compensation, plus 1.6% of
        Past Service Compensation in excess of $22,800. ("Past Service
        Compensation" is the employee's average compensation for the years 1991,
        1992, and 1993); plus

      (ii)for each full or partial year of benefit service beginning on or
        after January 1, 1994, 1.2% of the employee's compensation during such
        year up to the employee's "Covered Compensation" amount for the year,
        plus 1.7% of the employee's compensation in excess of such "Covered
        Compensation" amount. ("Covered Compensation" for each year is
        determined by the employee's age and is taken from a Social Security
        Covered Compensation Table published annually in accordance with IRS
        regulations. For any given age, the "Covered Compensation" amount in the
        Table represents the average of the Social Security taxable wage bases
        over the 35-year period ending in the year someone that age will reach
        Social Security normal retirement age.)

In addition to the Plan, the Corporation initiated effective May 1, 1994, a
Supplemental Retirement Plan (the "SERP") to supplement the Plan and ESOP and
make up for benefits which were lost because of the dollar limits imposed by
sections 401(a)(17) and 415 of the Code on benefits and contributions under
those plans. The SERP results in highly compensated employees receiving
retirement benefits calculated on the same basis as other employees. Employees
become eligible for benefits under the SERP whenever: (a) the employee has
service after the effective date; (b) the employee becomes eligible for benefits
under the Plan or an allocation under the ESOP; and (c) the employee's benefit
or allocation is limited by section 401(a)(17) of the Code or by the dollar
amount under section 415 of the Code, or both. The benefit paid under the SERP
is the difference between the Plan benefit calculated as described above and the
amount that would have been paid under the Plan in the absence of the dollar
limits in sections 401(a)(17) and 415 of the Code; plus the difference between
the amount of ESOP benefit allocated to the participant under the ESOP after
1988 and the amount that would have been allocated in the absence of the dollar
limits in sections 401(a)(17) and 415 of the Code, plus dividends that would
have been paid on such shares after May 1994. Such benefit payments are made at
the time that the benefits under the Plan or

                                      -11-



ESOP, as applicable, are paid, or earlier upon an adverse IRS ruling. The
Compensation Committee of the Board of Directors may amend or terminate the SERP
at any time so long as rights already accrued at the time of such amendment or
termination are preserved. The following Pension Plan Table shows the estimated
annual benefits payable upon retirement at age 65 (including benefits under the
SERP) in the specified compensation and years of service classifications.

      (FN1) Represents at least 125% of the maximum compensation for the year
            ended December 31, 2004.

      (FN2) Estimates assume all service is after January 1, 1994, and Social
            Security Covered Compensation as defined above is $60,000 for all
            years. The estimates do not include the ESOP benefit pursuant to the
            SERP, which is not determined by years of service and final
            compensation.


The portion of an employee's benefit attributable to years of benefit service in
excess of 35 years is limited to 1.0% of his Past Service Compensation for
purposes of (i), above; and to 1.2% of his annual compensation for purposes of
(ii), above. Notwithstanding the foregoing, an employee's compensation taken
into account for any Plan year after 1993 shall not exceed $150,000 (or such
other amount as may be prescribed for the relevant plan year by the Secretary of
the Treasury pursuant to section 401(a)(17) of the Code). As previously
described, the SERP will pay benefits on the additional compensation above that
amount. The plan benefits are not subject to deduction for Social Security or
other offset amounts. For each named executive officer listed on the Summary
Compensation Table, pension benefits are reported in the following table.

               EMPLOYMENT CONTRACTS AND TERMINATION OF EMPLOYMENT
                       AND CHANGE IN CONTROL ARRANGEMENTS

EMPLOYMENT AGREEMENT.

Mr. Declusin entered into an employment agreement with the Corporation dated
August 1, 2003, to serve as President and Chief Executive Officer. The agreement
expires on December 31, 2005. The compensation provisions of the employment
agreement are described in the accompanying report of the Compensation Committee
of the Board of Directors. The other provisions covered in the employment
agreement are vacation, benefit plans expenses, fringe benefits and termination.
As part of the agreement, Mr. Declusin has agreed not to compete with the
Corporation for a one-year period following any voluntary termination without
"good reason" (as defined in the agreement). Except as described below, no other
named executive has an agreement related to employment with the Corporation.

SEVERANCE AGREEMENT.

Mr. Corvin entered into a separation agreement and general release with the
Corporation effective July 31, 2003, and resigned as an officer and director of
the Corporation and each of its subsidiaries. Under the agreement, Mr. Corvin is
on paid administrative leave through the earlier of April 6, 2006, or until he
becomes employed on a full-time basis with another employer. During the period,
the Corporation will pay Mr. Corvin $550,000 annually, provide outplacement
services and allow Mr. Corvin to participate in certain of the Corporation's
health and welfare benefit programs; however, Mr. Corvin will not be eligible to
participate in any bonus, vacation, stock options, ESOP contributions and other
similar programs. Mr. Corvin also agreed not to compete with the Corporation.

CHANGE IN CONTROL AGREEMENTS.

The Corporation entered into change-in-control agreements ("Agreements") with
Messrs. Declusin, Adams, Lawrence, Rowan, Simon and certain other key employees
("Employees"). Change in Control is defined to include, among other things, the
transfer of 25% or more of the Corporation's voting securities to any person or
entity other than the ESOP or the election of a majority of directors who were
not nominated by the then current Board. The Agreements provide, among other
things, for severance compensation in the event that an Employee's employment is
terminated by the employer without cause or by the Employee with good reason,
all as defined in the Agreements, during the three-year period following a
Change in Control. Severance compensation is to be calculated as the sum of (i)
three times the Employee's annual base salary as of the date of termination or
immediately prior to the Change in Control, whichever is greater; (ii) an amount
equal to the lump sum present actuarial value of the excess, if any, of the
normal retirement allowance to which the Employee would have been entitled under
the Pension Plan, assuming that the Employee continued as an active participant
under such plan, without change in his or her rate of annual pay, until the
earlier of his or her 65th birthday or the tenth anniversary of the date of the
Change in Control, over the normal retirement allowance to which the Employee is
actually entitled under such plan as of the date of termination; and (iii) group
health benefits substantially similar to what the Employee was receiving
immediately prior to the date of termination. In addition, the Corporation will
pay an additional amount to the Employee to compensate for excise taxes the
Employee is required to pay on "excess parachute payments."

INDEMNIFICATION AGREEMENTS.

The Corporation has entered into Indemnification Agreements with each director
and certain executive officers (an "Indemnified Person"). Each agreement
provides that the Corporation shall indemnify the Indemnified Person to the
fullest extent permitted by applicable law or the Corporation's Restated
Certificate of Incorporation, including if and when the Indemnified Person is or
was a party or is threatened to be made a party to any action, suit,
arbitration, investigation, administrative hearing, or any other proceeding (a
"Proceeding") because of the Indemnified Person's status or former status as a
director, officer, or other agent of the Corporation or because of anything done
or not done by the Indemnified Person in such capacity, against all expenses and
liabilities actually and reasonably incurred by the Indemnified Person or on the
Indemnified Person's behalf in connection with the investigation, defense,
settlement, or appeal of such Proceeding. The Corporation will advance to the
Indemnified Person all reasonable defense expenses incurred in defense of any
Proceeding. Further, each agreement provides that upon the acquisition of 30% or
more of the outstanding shares of Common Stock, other than by the Corporation or
the ESOP, without approval by a majority of the Corporation's Board prior to
such acquisition, the Corporation will obtain and maintain over the term of the
agreement an irrevocable standby letter of credit on terms satisfactory to the
Indemnified Person in an appropriate amount (but not less than $500,000) naming
the Indemnified Person as the beneficiary in order to secure the Corporation's
obligation under the agreement. Finally, each agreement provides that the
Corporation will purchase and maintain director and officer insurance with
coverage at least comparable to its then current insurance for the Indemnified
Person for the term of the agreement. The Corporation may elect to not purchase
the required insurance if the insurance is not reasonably available or if, in
the reasonable business

                                      -13-



judgment of the directors of the Corporation, either the premium cost for such
insurance is disproportionate to the amount of coverage or the coverage provided
by such insurance is so limited that there is insufficient benefit from such
insurance.

           COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

During 2003 the Compensation Committee members were Stephen P. Reynolds,
Chairman, and Frank M. Walker. William Swindells was an ex officio member until
August 2003, when he became a member of the Committee. James E. Declusin was a
member of the Committee until his appointment as President and CEO on August 1,
2003.


                       BOARD COMPENSATION COMMITTEE REPORT
                            ON EXECUTIVE COMPENSATION
--------------------------------------------------------------------------------
During 2003, subject to approval of the Board, the Compensation Committee (the
"Committee") of the Board established the general compensation policies of the
Corporation and the compensation plans and specific compensation levels for
executive officers and established guidelines for the compensation of other
personnel. The 2003 Committee was composed of independent, non-employee
directors. In January 2004, the Committee adopted a new charter, which expanded
and clarified its purposes, duties and responsibilities in light of the New York
Stock Exchange listing standards.

COMPENSATION PRINCIPLES

The Corporation believes that the compensation program should be designed to
attract, retain, and motivate talented employees to contribute to the
Corporation's long-term success. To ensure that compensation is competitive, the
Corporation periodically collects and analyzes compensation practices of
companies and competitors in its location and industry and uses that information
as the basis to determine whether the Corporation's compensation program is in a
competitive range.

The Corporation maintains the philosophy that compensation of all employees
should be directly and materially linked to operating and financial performance
of the Corporation, and that incentive compensation should be a greater part of
total compensation for more senior positions. To achieve this linkage, incentive
compensation programs are provided based upon performance measures relevant to
the employee or executive participants, for example quality production, cost
reduction, net income, operating income, or return on assets.

These principles align all employee compensation with the Corporation's
objectives, operating strategy, management initiatives, and financial
performance. Within this overall philosophy, the Corporation's objectives are
to:

[BULLET] Offer a total compensation program that takes into consideration the
         compensation practices of comparable companies with whom the
         Corporation competes for executive talent.

[BULLET] Support a performance-oriented environment in which everyone is working
         together in pursuit of the Corporation's short-term and long-term
         goals.

[BULLET] Maximize the Corporation's long-term growth and profitability and the
         enhancement of stockholder value.

COMPARATIVE EVALUATION

The Corporation seeks to align total compensation for its employees and
executive officers with that of comparable executive positions in other
manufacturing and steel companies. In 2001, the Corporation retained an
independent consulting firm to review and benchmark executive and employee
compensation. Overall, employee compensation was found to be at or slightly
above market. The consultant's report to the committee on executive compensation
compared the base salary, incentive compensation, and other benefits of the
Corporation to other durable goods manufacturing companies (the "Report"). The
Report focused on total compensation for the eight most senior executive
positions. In preparing the Report, the consulting firm reviewed the executive
position descriptions and competitive practices and pay levels for numerous
durable goods manufacturing companies (including steel companies). The Report
concluded that while executive base salaries were competitive, the Corporation's
incentive compensation for executives was below market for comparable positions.
As a result, the Corporation planned to gradually increase the opportunity for
incentive compensation.

In 2003, the Corporation performed an internal review and benchmark of executive
and employee compensation using the Report as guidance. Based on the
information, the Committee found that executive base salaries were competitive,
but that incentive compensation for executives was still below market for
comparable positions. For 2004, the Annual Incentive Plan target bonus levels
were increased.

                                      -14-


EXECUTIVE COMPENSATION ELEMENTS

There are four elements in the Corporation's executive officer compensation
program, all determined by position, individual performance, and corporate
performance and profitability.

      BASE SALARY

      The Committee sets base salary levels for all officers at levels that are
      competitive with similar positions at other comparable companies, and that
      reflect the responsibilities and performance of the individuals.

      INCENTIVE COMPENSATION

      Executive officers participate in the Annual Incentive Plan ("AIP") and
      are excluded from the employee profit participation and gainsharing
      incentive plans. The AIP is designed to reward participants with an annual
      bonus if the results of certain pre-determined financial measurements meet
      or exceed the benchmarks set by the Board of Directors.  From 2000 to
      2003, the annual incentive compensation was determined based upon the
      Division's and Corporation's actual return on assets for the year, and
      calculated for each participant at a predetermined percentage of base
      salary. For 2004, AIP is based on the Corporation's Net Income.

      LONG-TERM INCENTIVE (STOCK OPTION) PLAN

      In April 2000, stockholders approved a long-term incentive plan which is a
      non-qualified stock option plan. No options were granted during 2003. See
      section entitled "Option Grants During Fiscal 2003" on page 11.

      EMPLOYEE STOCK OWNERSHIP PLAN (ESOP)

      The Corporation has an ESOP for qualified employees of Oregon Steel Mills,
      Inc. Annual contributions to the ESOP, which are at the discretion of the
      Board, are based upon the financial performance of the Corporation. The
      annual contribution may be in cash or Common Stock but historically has
      been in Common Stock. No contributions have been made to the ESOP since
      1997. The Corporation also has a SERP (as discussed previously under the
      heading "Defined Benefit Retirement Plans") whereby the SERP supplements
      pension and ESOP benefits, making up for benefits which were lost because
      of the dollar limits imposed by sections 401(a)(17) and 415 of the Code.

CHIEF EXECUTIVE OFFICER ("CEO") COMPENSATION

The Committee used these compensation principles with respect to the
compensation of Mr. Declusin, who became President and CEO of the Corporation on
August 1, 2003. Mr. Declusin and the Corporation entered into an employment
agreement which expires on December 31, 2005. Under the agreement, Mr.
Declusin's base salary is $500,000 and he receives 40,000 restricted shares of
the Corporation's stock, 20,000 of which vested on August 1, 2003, and 20,000
will vest on August 1, 2004, subject to forfeiture. In addition, Mr. Declusin is
eligible to participate in the Annual Incentive Plan (at an initial target bonus
of 37% for 2003) and other incentive programs, including stock options. Stock
options to purchase 1,500 shares of the Corporation's stock were issued to Mr.
Declusin in April 2003 under the non-management director plan and no stock
options were granted to Mr. Declusin in 2003 as CEO. For the 2003 period, Mr.
Declusin will not receive any additional compensation under the AIP or ESOP
plans.

The Corporation does not have any "Excessive Employee Remuneration" as defined
in section 162(m) of the Code.

                AUDIT COMMITTEE REPORT OF THE BOARD OF DIRECTORS
--------------------------------------------------------------------------------
The Board of Directors has a separately designated audit committee established
in accordance with Section 3(a)(58) of the Securities Exchange Act. The Audit
Committee members in 2003 were Mr. Demorest, Chair, Messrs. Neun, Parkinson and
Sproul as members and Mr. Swindells as ex officio member. As determined by the
Board, each Audit Committee member is "independent" as defined by the New York
Stock Exchange listing standards. The Board also determined that Mr. Demorest is
an "audit committee financial expert" and he is independent. Furthermore, the
Board determined that Mr. Neun's simultaneous service on the audit committees of
more than two other public companies would not impair his ability to effectively
serve on the Corporation's Audit Committee. The Board of Directors and the Audit
Committee believe that the Audit Committee's current member composition
satisfies the New York Stock Exchange listing standards.

The Audit Committee oversees the accounting and financial reporting processes of
the Corporation and audits of the financial statements of the Corporation.
Management has the primary responsibility for the financial statements and the
reporting process, including the systems of internal controls. In fulfilling its
oversight responsibilities, the Audit Committee reviewed the audited financial
statements in the Annual Report with management including a discussion of the
quality, not just the acceptability, of the accounting principles, the
reasonableness of significant judgments, and the clarity of disclosures in the
financial statements. The Corporation has adopted an amended and restated
written charter of the Audit Committee, a copy of which was attached as Appendix
B to this 2004 Proxy Statement.

The Audit Committee reviewed with the independent auditors, who are responsible
for expressing an opinion on the conformity of the Corporation's audited
financial statements to generally accepted accounting principles, their
judgments as to the quality, not just the acceptability, of the Corporation's
accounting principles and such other matters as are required to be discussed
with the Committee under generally accepted auditing standards, including
Statement on Auditing Standards No. 61, Communication with Audit Committees. In
addition, the Audit Committee received from the independent auditors the written
disclosures and letter required by Independence Standards Board No. 1
(Independence Discussions with Audit Committees) and discussed with them their
independence from the Corporation and its management. The Audit Committee has
considered whether the independent auditor's provision of non-audit services to
the Corporation is compatible with maintaining the auditor's independence, and
determined that it is.

The Audit Committee's pre-approval policies and procedures require pre-approval
of all non-prohibited audit and non-audit services provided by the independent
auditors to the Corporation and require specific written pre-approval relating
to any type of non-prohibited services where fees in the aggregate are expected
to exceed $10,000 ("Material Services"). The Audit Committee may delegate the
authority to grant pre-approval of Material Services to a designated member of
the Audit Committee and Mr. Demorest was named the designated member. The
Corporation has determined that certain non-audit services are prohibited. At
each Audit Committee meeting, the Audit Committee reviews a report summarizing
the services provided by the independent auditors and a list of services to be
pre-approved since its last regularly scheduled meeting.

The function of the Audit Committee members is not intended to duplicate or to
certify the activities of management and the independent auditor, nor can the
Committee certify that the independent auditor is "independent" under applicable
rules. The Committee serves a board-level oversight role, in which it provides
advice, counsel, and direction to management and the auditors on the basis of
the information it receives, discussions with management and the auditors, and
the experience of the Committee's members in business, financial and accounting
matters.

In reliance on the reviews and discussions referred to above, the Audit
Committee recommended to the Board of Directors, and the Board has approved,
that the audited financial statements be included in the Corporation's Annual
Report on SEC Form 10-K for the year ended December 31, 2003, for filing with
the Securities and Exchange Commission.


                    RELATIONSHIP WITH INDEPENDENT ACCOUNTANTS

On July 7, 2003, PricewaterhouseCoopers LLP ("PricewaterhouseCoopers") was
dismissed as certifying accountants by the Audit Committee. The audit reports of
PricewaterhouseCoopers on the Corporation's financial statements for the years
ended December 31, 2002 and 2001, did not contain any adverse opinion or
disclaimer of opinion and were not qualified or modified as to uncertainty,
audit scope or accounting principles. During the Corporation's two most recent
fiscal years and through July 7, 2003, there were no disagreements with
PricewaterhouseCoopers on any matter of accounting principles or practices,
financial statement disclosure or auditing scope or procedure, which
disagreements, if not resolved to the satisfaction of PricewaterhouseCoopers,
would have caused PricewaterhouseCoopers to make reference thereto in connection
with its reports on the finan-

                                      -16-


cial statements for such years. During the two most recent fiscal years and
through July 7, 2003, there have been no reportable events (as defined in
Regulation S-K Item 304(a)(1)(v)). The Corporation delivered a draft copy of its
Form 8-K report to PricewaterhouseCoopers on July 7, 2003. Concurrently with
that delivery, the Corporation requested that PricewaterhouseCoopers furnish it
with a letter addressed to the Securities and Exchange Commission (the "SEC")
stating whether PricewaterhouseCoopers agrees with the above statements and, if
not, stating the respects in which PricewaterhouseCoopers does not agree. The
letter of PricewaterhouseCoopers to the SEC dated July 7, 2003, indicating that
they agree with the statements concerning PricewaterhouseCoopers in such Form
8-K was attached as Exhibit 16.1 to the Form 8-K filed on July 10, 2003.

On July 7, 2003, KPMG LLP ("KPMG") was engaged as new independent accountant by
the Audit Committee. During the Corporation's two most recent fiscal years and
through July 7, 2003, the Corporation did not consult with KPMG regarding either
(1) the application of accounting principles to a specified transaction, either
completed or proposed; or the type of audit opinion that might be rendered on
the Corporation's financial statements, and neither a written report was
provided to the Corporation or oral advice was provided that KPMG concluded was
an important factor considered by the Corporation in reaching a decision as to
the accounting, auditing, or financial reporting issue; or (2) any matter that
was either the subject of a disagreement, as defined in Item 304(a)(1)(iv) of
Regulation S-K, or a reportable event pursuant to Item 304(a)(1)(v) of
Regulation S-K.

In addition to performing the audit of the Corporation's consolidated financial
statements, PricewaterhouseCoopers LLP and/or KPMG LLP provided various other
services during the last two years. The aggregate fees billed for the last two
years for each of the following categories of services are set forth below:

            2003        Audit Fees(FN1)                           $472,000

                        PROPOSAL 2: STOCKHOLDER PROPOSAL
--------------------------------------------------------------------------------
Mr. Mark Latham, 177 Telegraph Road, #302, Bellingham, WA 98226, owner of 2,000
shares of the Corporation, has proposed the adoption of the following resolution
and has furnished the following statement in support of his proposal:

                             PROXY ADVISORY PROPOSAL

      WHEREAS, many shareowners lack the time and expertise to make the best
      voting decisions, yet prefer not to always follow directors'
      recommendations, because of possible conflicts of interest;

      WHEREAS, shareowners have a common interest in obtaining sound independent
      advice, but often insufficient private interest to justify paying for it
      individually (the "free-rider" problem);

      THEREFORE, BE IT RESOLVED that Oregon Steel Mills, Inc. shareowners
      request the Board of Directors to hire a proxy advisory firm for one year,
      to be chosen by shareowner vote. Shareowners request the Board to take all
      necessary steps to enact this resolution in time to hold the vote at
      year-2005 shareowner meeting, with the following features:

      To insulate advisor selection from influence by the Corporation's
      management, any proxy advisory firm could put itself on the ballot by
      paying an entry fee, declaring the price (no more than $8,000) for
      advisory services for the coming year, and providing the address of a
      website describing their proposed services and qualifications.

      The winning candidate would be paid its declared price by the Corporation,
      and make advice freely available to all Corporation shareowners for the
      subsequent year, on all matters put to shareowner vote except director
      elections. (Advice on director elections is excluded to satisfy SEC rule
      14a-8(i)(8).)

      Performance of the advisory firm would not be policed by the Corporation's
      management, but rather by gain or loss of the advisor's reputation and
      future business.

      Brief summary advice could be included in the Corporation proxy, with
      references to a website and/or a toll-free phone number for more detail.
      The decision of whether to hire proxy advisory firms in later years would
      be left open.

      SUPPORTING STATEMENT:
      ---------------------
      The proxy advisor would be paid with Corporation funds to give
      shareowners an independent professional opinion. Independence would be
      further enhanced by having shareowners choose the proxy advisor. This
      could also increase competition in the proxy advisory business, because
      new entrants could earn fees on a company-by-company basis, without
      covering thousands of companies.

      Left to Give Advice?":

      Services... A monopoly of shareholder advice doesn't sit well with some."

      for corporate management nominees is also mixed with majorities of
      shareholders having WITHHELD SUPPORT from a management nominee."

      The conflicts of interest among managers, directors and shareowners are
      described in Robert Monks and Nell Minow's 1996 book Watching the
      Watchers, along with shareowners "free rider" and "rational ignorance"
      problems.

                 CORPORATION'S RESPONSE TO STOCKHOLDER PROPOSAL

The Board of Directors recommends a vote AGAINST approval of the Stockholder
Proposal as the implementation of the proposal described above would not be in
the best interests of the Corporation or you, our stockholders. In the opinion
of the Board of Directors:

[BULLET] The Board consists of eight Directors, seven of whom are "independent
         directors" and one is a member of management. The directors are
         experienced individuals who are familiar with the Corporation's
         business and the markets in which the Corporation operates. The Board
         of Directors believes it is sufficiently independent of management to
         avoid conflicts of interest. Adding the advice of an outside firm (at
         the Corporation's expense) would not assist the Board or stockholders
         in furthering the Corporation's objectives or otherwise be in the
         stockholder's best interests.

[BULLET] The Board of Directors is committed to providing Corporation
         stockholders with useful voting recommendations and information on
         which to make voting decisions. The Board bases its recommendations on
         its knowledge of the Corporation, its strategic plans for the business
         and input from management and outside advisers. We do not believe
         adding the advice of an unsupervised firm at our expense would be in
         the interests of our stockholders.

[BULLET] This proposal calls for the Corporation to hire a proxy advisory firm
         without screening, input or review by the Board or management of the
         quality of the firm or its work product. Even our independent auditors
         are selected and reviewed by the Audit Committee. The Board of
         Directors does not believe it is in the best interests of our
         stockholders to spend funds to hire a proxy advisory firm without first
         evaluating the need for such advice and the quality of the firm's
         work, its recommendations and the process by which such recommendations
         are made.

[BULLET] The proposal calls for the firm to be paid without regard to the
         reasonableness of this compensation for the work performed. While the
         proposal purports to cap the fees paid to the elected proxy advisory
         firms, we believe the actual costs of the proposal will be greater. We
         do not believe it is a good idea for us to abdicate our
         responsibilities to evaluate the engagement, services and compensation
         of outside advisers, and do not believe we should provide an open forum
         in our proxy materials for an unknown and unsupervised firm.

[BULLET] The Stockholder Proposal involves additional cost to the proxy process.

[BULLET] There is a significant volume of published research and other
         literature regarding the Corporation and issues of importance to the
         Corporation's stockholders (made even more accessible by the Internet),
         and a proxy advisory firm would offer little marginal benefit in
         communicating with stockholders.

THEREFORE, FOR ALL OF THE REASONS STATED ABOVE, THE BOARD OF DIRECTORS URGES
STOCKHOLDERS TO VOTE "AGAINST" THIS PROPOSAL 2.



                                  REQUIRED VOTE

The affirmative vote of the majority of the shares present in person or
represented by proxy at the meeting and entitled to vote on the stockholder
proposal is required to approve the stockholder proposal, which is framed as a
"recommendation" to the Board. An abstention is treated as being present and
entitled to vote on the matter and, therefore, has the effect of a vote against
the stockholder proposal. A broker "non-vote" is treated as not being entitled
to vote on the matter and, therefore, is not counted for purposes of determining
whether the stockholder proposal has been approved.

                                      -19-





                                  OTHER MATTERS

The Board knows of no other matters to be brought before the Annual Meeting.
However, if any other business properly comes before the meeting, the persons
named in the accompanying form of proxy will vote or refrain from voting thereon
in accordance with their judgment pursuant to the discretionary authority given
them in the proxy.

                  STOCKHOLDER PROPOSALS FOR 2005 ANNUAL MEETING

Stockholder proposals submitted for inclusion in the 2005 proxy materials and
consideration at the 2005 Annual Meeting of Stockholders must be received by the
Corporation no later than November 30, 2004, and no earlier than October 31,
2004. Any such proposal should comply with the rules promulgated by the
Securities and Exchange Commission governing stockholder proposals submitted for
inclusion in proxy materials.

In order to be considered at the 2005 Annual Meeting of Stockholders, written
notice of a non-Rule 14a-8 stockholder proposal or director nomination must
contain the information required by the Corporation's bylaws and must be
received by the Corporation no later than November 30, 2004 and no earlier than
October 31, 2004.

--------------------------------------------------------------------------------
The Nominating/Corporate Governance and Compensation Committee ("Committee") is
a committee of the Board of Directors ("Board") of Oregon Steel Mills, Inc.

PURPOSES

applicable to the Company; and (c) oversee the evaluation of the Board and
Company management.

The purposes of the Committee in the areas of Compensation are to have a direct
responsibility to (a) review and approve corporate goals and objectives relevant
to CEO compensation, evaluate the CEO's performance in light of those goals and
objectives, and either as a committee or together with the other independent
directors (as directed by the Board), determine and approve the CEO's
compensation based on this examination; (b) make recommendations to the Board
with respect to non-CEO compensation, incentive compensation plans and
equity-based plans; and (c) produce an annual report on executive compensation
as required by the SEC for inclusion in the proxy statement or Form 10-K.

COMMITTEE MEMBERSHIP

meet the "independence" requirements set forth in the Company's Corporate
Governance Guidelines and all other legal and exchange requirements.

         by the Board to the stockholders in the annual proxy statement or any
         director nominees to be elected by the Board to fill interim director
         vacancies consistent with criteria approved by the Board. It is

         with appropriate skills and characteristics and communicate such

               criteria and process for evaluating the effectiveness of the

         Chair of the Board and/or Lead Director.

COMPENSATION

   1. CEO AND EXECUTIVE COMPENSATION

      (a) Review and approve corporate goals and objectives relevant to CEO
          compensation, evaluate the CEO's performance in light of those goals

          approve the CEO's compensation level based on this evaluation. In
          determining the long-term incentive component of CEO compensation, the
          Committee should consider, among other factors, the Company's
          performance and relative stockholder return, the value of similar
          incentive awards to CEOs at comparable companies, and the awards given
          to the Company's CEO in past years. To avoid confusion, the Committee
          is not precluded from approving awards (with or without ratification
          of the Board) as may be required to comply with applicable tax laws
          (i.e., Rule 162(m)).

                             AUDIT COMMITTEE CHARTER
--------------------------------------------------------------------------------
The Audit Committee is a committee of the Board of Directors. The Audit
Committee's purpose is to assist Board oversight of: (a) the integrity of the
Company's financial statements, (b) the Company's compliance with legal and
regulatory requirements, (c) the independence and qualifications of the outside
auditor, and (d) the performance of the Company's internal audit function and
outside auditor.

The Audit Committee shall have the power to conduct or authorize investigations
into any matters within the Committee's scope of responsibilities. The Committee
shall be empowered to retain independent counsel, accountants, and other
advisers, as it determines necessary to carry out its duties. The Committee will
perform such other functions as assigned by law, the Company's charter or
bylaws, or the Board of Directors.

The Company must provide for appropriate funding, as determined by the Audit
Committee, in its capacity as a committee of the Board of Directors, for payment
of: (a) compensation to any registered public accounting firm engaged for the
purpose of preparing or issuing an audit report or performing other audit,
review or attest services for the Company; (b) compensation to any advisers
employed by the Audit Committee; and (c) ordinary administrative expenses of the
Audit Committee that are necessary or appropriate in carrying out the Audit
Committee's duties.

MEMBERSHIP

The membership of the Audit Committee shall consist of three or more independent
members of the Board of Directors who shall be appointed by the Board of
Directors. Independence shall be as determined in accordance with New York Stock
Exchange standards and the Securities and Exchange Commission rules. Each member
must be financially literate, as such qualification is interpreted by the Board
of Directors in its business judgment. At least one member must have accounting
or related financial management expertise as the Board of Directors interprets
such qualification in its business judgment and if such person meets the
definition of a financial expert set out in the rules and regulations of the
Securities and Exchange Commission, it will be presumed that such person has
accounting or related financial management expertise. Committee members will not
serve simultaneously on the audit committees of more than two other public
companies, unless the board determines that such simultaneous service would not
impair the ability of such member to effectively serve on the Company's Audit
Committee.

MEETINGS

The Committee shall meet at least two times per year or more frequently as it
deems necessary to fulfill its responsibilities. The Committee may request
members of management or others to attend the meeting and provide pertinent
information as necessary. The Audit Committee shall meet separately,
periodically, with the outside auditor, the manager of internal audit, and
management.
