                                PROXY STATEMENT
 
                            ------------------------
 
    This Proxy Statement and the accompanying Notice of Annual Meeting of
Stockholders are being furnished in connection with the solicitation of proxies
by the Board of Directors of Clean Harbors, Inc., a Massachusetts corporation
(the "Company"), for use at the Annual Meeting of Stockholders of the Company to
be held at Swissotel, 1 Avenue de Lafayette, Boston, Massachusetts, on June 17,
1998, commencing at 9:30 a.m., local time, and any adjournment thereof.
 
                               PROXY SOLICITATION
 
    Proxies in the accompanying form, properly executed and received prior to
the meeting and not revoked, will be voted as specified or, if no instructions
are given, will be voted in favor of the proposals described herein. Proxies may
be revoked at any time prior to the meeting by written notice given to the Clerk
of the Company. The cost of this solicitation shall be borne by the Company.
Solicitations of proxies by telephone or in person may be made by the Company's
directors, officers or other employees, but any such solicitation will be
carried on during working hours and for no additional cost, other than the time
expended and telephone charges in making such solicitation. This Proxy Statement
and the accompanying proxy form are scheduled to be mailed to stockholders
beginning on May 5, 1998.
 
                      INFORMATION AS TO VOTING SECURITIES
 
    The holders of the Company's Common Stock and Series B Convertible Preferred
Stock vote as a single class with respect to the election of directors and most
other matters. Each issued and outstanding share of the Company's Common Stock,
$.01 par value per share, and each issued and outstanding share of the Company's
Series B Convertible Preferred Stock, $.01 par value per share, is entitled to
one vote. Only stockholders of record at the close of business on May 1, 1998
will be entitled to vote at the meeting. On April 1, 1998, there were 10,195,016
shares of Common Stock and 112,000 shares of Series B Convertible Preferred
Stock of the Company outstanding and entitled to vote. Votes cast by proxy or in
person at the Annual Meeting will be counted by persons appointed by the Company
to act as election inspectors for the meeting.
 
    The election of the Class III directors requires the affirmative vote of the
holders of a plurality of the shares of both classes of stock represented at the
meeting. Approval of any other matters which may properly come before the
meeting will require the affirmative vote of the holders of a majority of the
shares represented and entitled to vote on such proposals at the meeting. Votes
withheld from any nominee for election as a director, abstentions, and broker
"non-votes" are counted as present or represented for purposes of determining
the presence of a quorum for the meeting. Therefore, votes withheld from any
nominee for director will have the effect of "against" votes. Broker "non-votes"
occur when a nominee holding shares for a beneficial owner votes on one
proposal, but does not vote on another proposal because the nominee does not
have discretionary voting power and has not received instructions from the
beneficial owner. Usually, this would occur when brokers holding stock in
"street name" have not received any instructions from clients, in which case the
brokers (as holders of record) are permitted to vote on "routine" proposals but
not on non-routine matters. The election of directors is considered a routine
matter, and therefore it is anticipated that broker "non-votes" will not occur
with respect to such election. Because such brokers will not be entitled to vote
at the meeting on any non-routine matter, their broker "non-votes" will not have
any effect on the voting on such proposal.

One class of directors is elected each year for a term of three years. There are currently only two Class I directors, with a vacancy created by the resignation of David A. Eckert in January 1998. The Board of Directors is currently considering candidates to fill that vacancy for the remaining term of Class I Director which runs until the 1999 Annual Meeting. The term of the Class III Directors, Christy W. Bell and Daniel J. McCarthy, shall expire at the 1998 Annual Meeting, and the Board of Directors has nominated each of the foregoing to continue to serve as Class III Directors. UNLESS OTHERWISE SPECIFIED THEREIN, SHARES REPRESENTED BY THE ENCLOSED PROXY WILL BE VOTED AT THE ANNUAL MEETING TO ELECT CHRISTY W. BELL AND DANIEL J. MCCARTHY AS DIRECTORS OF THE COMPANY FOR A THREE-YEAR TERM, UNTIL THE 2001 ANNUAL MEETING OF STOCKHOLDERS AND UNTIL THEIR RESPECTIVE SUCCESSORS SHALL BE DULY ELECTED. IN THE EVENT THAT ONE OR MORE OF THE NOMINEES IS UNABLE TO STAND FOR ELECTION (WHICH EVENT IS NOT NOW CONTEMPLATED), THE HOLDERS OF THE ENCLOSED PROXY WILL VOTE FOR THE ELECTION OF A NOMINEE OR NOMINEES ACCEPTABLE TO THE REMAINING MEMBERS OF THE COMPANY'S BOARD OF DIRECTORS. THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE "FOR" THE PROPOSAL TO ELECT MESSRS. BELL AND MCCARTHY AS DIRECTORS. COMPENSATION OF DIRECTORS According to the Company's Equity Incentive Plan approved by stockholders at the 1992 Annual Meeting, each director who is not an employee of the Company receives upon election to the Board a grant of a five-year, non-qualified stock option to purchase that number of shares of the Company's Common Stock determined by multiplying 1,000 by the number of years or fraction thereof for which the director shall be elected, at the market price of the Common Stock on the date of election, vesting immediately as to the first 1,000 shares of any award and as to an additional 1,000 shares on each anniversary of the date of election. Awards to directors appointed to fill a vacancy on the Board for less than one year are prorated. During 1997, upon the election as directors to serve for a term of three years, Messrs. Preston and Waxlax, the only non-employees elected as a director, each received options for 3,000 shares at the market price of $1.6875 per share. Also during 1997, the Board appointed Paul W. Russo to serve as director for a term of two years and nine months for which he received options for 2,750 shares at the market price of $2.00 per share. Mr. Russo resigned as a director in February 1998, shortly after the resignation of Mr. Eckert, and his options will expire in May 1998. The Company's policy is to pay each director who is not an employee an annual retainer fee of $20,000 plus $1,000 for each board meeting attended, $750 for each committee meeting attended and $500 for board meetings conducted by telephone conference call. The Company also pays outside directors who are members of committees of the Board $1,000 for membership on a committee and an additional $1,500 for serving as chairman of a committee. Directors are reimbursed for expenses incurred in connection with service on the Board. Total fees paid to outside directors in 1997 were as follows: Bell $30,500; Kaslow $33,250; McCarthy $35,750; Preston $25,750; Russo $4,333; and Waxlax $30,500. BOARD COMMITTEES AND MEETINGS During 1997, the Board of Directors held six meetings, of which one was held by conference call. The Board of Directors has established an Audit Committee consisting of members of the Board of Directors who are not employed by the Company. During 1997, the Audit Committee consisted of 7 Messrs. Bell, Kaslow and McCarthy. The primary functions of the Audit Committee are to recommend the selection of independent public accountants, to review the scope of and approach to audit work, and to meet with and review the activities of the Company's accountants and the independent public accountants. During 1997, there were four meetings of the Audit Committee, of which one was held by conference call. The Board of Directors has also established a Compensation and Stock Option Committee. During 1997, the Compensation and Stock Option Committee consisted of three non-employee directors: Messrs. Kaslow, McCarthy and Waxlax. During 1997, there were five meetings of the Compensation and Stock Option Committee, of which one was held by conference call. In December 1997, the Board of Directors established a Corporate Governance Committee whose duties include those of a nominating committee. The Corporate Governance Committee consists of three directors: Messrs. Waxlax, McKim and McCarthy. This committee met once during 1997. During 1997, all directors attended at least 75 percent of the meetings of the Board and the committees of which they were members. COMPENSATION COMMITTEE REPORT The Compensation and Stock Option Committee of the Board of Directors (the "Committee"), consists of three outside directors whose responsibilities include the recommendation to the full Board of Directors of a compensation package for the Chief Executive Officer; review and approval of other senior executive officer compensation; review and approval of corporate management compensation policies; and management of the Company's stock option and equity incentive plans. COMPENSATION The fundamental philosophy of the Committee regarding executive compensation is to offer competitive compensation opportunities and to align individual compensation with the goals, values and priorities of the Company. Compensation for executive officers currently consists of three basic elements: base compensation and benefits, salary "at-risk", and awards of long-term equity incentives through non-qualified stock options. Base compensation and benefits for 1997 were determined based upon previous studies of comparable industry groups. Salary at risk payments were made pursuant to the Company's Management Incentive Program ("MIP") approved by the Committee for 1997. Under the 1997 MIP, which covered approximately 100 management positions in the Company, an individual could earn a bonus based upon any one or more of three components: (i) Company-wide success in meeting management's goals, including a threshold achievement of earnings before interest, taxes, depreciation and amortization ("EBITDA"); (ii) business segment net income; and (iii) net income of the individual's business unit. No bonuses were paid under the first component of the MIP because the Company failed to achieve its EBITDA goal. Field Services was the only business segment of the Company within which managers received bonuses for 1997 ranging from a minimum of $1,050 to a maximum of $6,850. The final element of compensation for executive officers is long-term equity incentives through grants of non-qualified stock option awards at the market price of the Company's Common Stock. Awards are designed to align the interests of executive officers with those of stockholders of the Company and to encourage long-term retention of executives through periodic vesting. Awards are made at current market price, and most options vest as to 20% at the end of each successive year of service. Options were awarded in 1997 to 6 employees of the Company. The amount of individual awards ranged from 2,000 to 100,000 shares based upon the individual's position and ability to positively impact Company results, adjusted according to his or her performance rating. In 1997, Mr. Eckert received options for 100,000 shares vesting over five years, which expired on April 24, 1998. The Chief Executive Officer, Alan S. McKim, did not receive any options during 1997. 8 CHIEF EXECUTIVE OFFICER COMPENSATION Base compensation of the Chief Executive Officer, Alan S. McKim, was increased by the Compensation Committee in the Spring of 1993 from $250,000 to $300,000. Mr. McKim, however, voluntarily continued to defer the implementation of such increase until March 1, 1997 when his new base compensation went into effect. Salary at risk payable to Mr. McKim for 1997 was to be based upon the Company's achievement of a base line EBITDA goal and various individual goals established with the Committee. Because the Company failed to achieve its EBITDA threshold, Mr. McKim did not receive any bonus for 1997. COMPLIANCE WITH INTERNAL REVENUE CODE SECTION 162(M) Section 162(m) of the Internal Revenue Code, enacted in 1993, generally disallows a tax deduction to publicly-held companies for compensation paid to certain executive officers, to the extent that compensation exceeds $1 million per officer in any year. The compensation paid to the Company's executive officers during the 1997 fiscal year did not exceed the $1 million limit per officer, and it is not expected that the compensation to be paid to the Company's executive officers in the foreseeable future will exceed that limit. Because of the unlikelihood that compensation payable to any of the Company's executive officers in the foreseeable future will approach the $1 million limit, the Compensation Committee has decided at this time not to take any other action to limit or restructure the elements of compensation payable to the Company's executive officers. The Compensation Committee will reconsider this decision should the individual compensation of any executive officer ever approach the $1 million level. Members of the Committee Daniel J. McCarthy John F. Kaslow Lorne R. Waxlax 9 COMPENSATION OF EXECUTIVE OFFICERS The following table sets forth compensation information for the Chief Executive Officer and the four other most highly compensated executive officers of the Company and its subsidiaries who were serving as executive officers at the end of 1997.

The amounts set forth under "Potential Realizable Value at Assumed Annual Rates of Stock Price Appreciation for Option Term" reflect required disclosures pursuant to regulations of the Securities and Exchange Commission. The actual value to be realized, if any, could be more or less than the assumed values depending upon the performance of the stock. Under the terms of the Company's Stock Option and Equity Incentive Plans, the Compensation and Stock Option Committee retains discretion, subject to plan limits, to modify the terms of outstanding options and to reprice the options. In 1997 no stock options were repriced, and no stock appreciation rights were awarded. OPTION GRANTS IN 1997

TERMINATION OF EMPLOYMENT AND CHANGE OF CONTROL AGREEMENTS Mr. Eckert was employed under an employment agreement through January 24, 1998. Mr. Eckert's employment agreement provided for a minimum base salary of $250,000, which was increased to $300,000 by the Compensation Committee of the Board of Directors effective March 1, 1997. Mr. Eckert was entitled to participate in the Company's management bonus plan, which was based upon the Company's achievement of certain targets of earnings before interest, taxes, depreciation and amortization (EBITDA). Because the Company did not achieve its EBITDA target during 1997, Mr. Eckert did not receive a bonus for 1997. In 1996, under his employment agreement, Mr. Eckert received options for 250,000 shares of the Company's Common Stock at market price ($3.00) upon commencement of his employment, as well as normal employee benefits. In December of 1996, these options were repriced to $2.125 per share. In 1997, the Compensation Committee of the Board of Directors granted Mr. Eckert options on 100,000 additional shares of Common Stock, of which 50,000 were granted with an exercise price of $1.6875 and 50,000 were granted with an exercise price of $2.50. The market value of the options granted to Mr. Eckert in 1997 was $1.5625 on the date of grant. On January 24, 1998, Mr. Eckert resigned from the Company. On March 8, 1998, Mr. Eckert and the Company entered into an agreement which modified the severance provisions of his employment agreement to provide that Mr. Eckert could receive 75% of his base salary of $300,000, or an initial severance of $225,000. He is entitled to receive additional severance of $25,000 per month commencing October 25, 1998 to a maximum of $75,000, if he remains unemployed at that time. Mr. Eckert's vested options terminated on April 24, 1998. The Company provides "change of control" protection under stock option agreements awarded to executive officers. Some of those agreements provide that options will automatically fully vest upon a change of control, while others provide that if an employee is involuntarily terminated or experiences a change of position and a reduction in salary or relocation within twelve months of a change of control, the employee's options become fully vested. 12 PERFORMANCE GRAPH The following graph compares the five-year return from investing $100 on January 1, 1993 in each of Clean Harbors, Inc.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Section 16(a) of the Securities Exchange Act of 1934 requires the Company's executive officers and directors, and persons who beneficially own more than 10% of a registered class of the Company's equity securities, to file reports of ownership and changes of ownership with the Securities and Exchange Commission. Copies of those reports are to be furnished to the Company.
