SECURITY AND ISSUER This Schedule 13D relates to the Common Stock, $0.10 par value per share (the "Common Stock") of OHM Corporation ("OHM"), an Ohio corporation. The address of the principal executive offices of OHM is 5445 Triangle Parkway, Suite 400, Norcross, Georgia 30092. ITEM 2. IDENTITY AND BACKGROUND This statement is being filed by International Technology Corporation, a Delaware corporation ("IT" or the "Company"). The address of IT's principal executive offices is 2790 Mosside Boulevard, Monroeville, Pennsylvania 15146- 2792. IT provides a wide range of environmental management services and technologies, including the assessment, engineering, and remediation of situations involving hazardous materials and pollution prevention and minimization. IT was incorporated in 1983; the earliest antecedent of the Company commenced operations in California in 1926. During the last five years, IT has not been convicted in any criminal proceeding (excluding traffic violations or similar misdemeanors). During the last five years, IT has not been a party to any civil proceeding of a judicial or administrative body of competent jurisdiction and has not been and is not currently subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATIONS Not applicable. ITEM 4. PURPOSE OF TRANSACTION IT has entered into an Agreement and Plan of Merger, dated January 15, 1998 (the "Merger Agreement"), among IT, OHM and IT-Ohio, Inc. ("Purchaser"). Pursuant to the Merger Agreement, Purchaser, a wholly owned subsidiary of IT, is making a tender offer (the "Offer") to purchase 13,933,000 shares of Common Stock of the OHM (each, a Share and collectively, the Shares) at a price of $11.50 per Share, net to the tendering shareholder in cash, subject to the terms and conditions set forth in the Offer to Purchase, dated January 16, 1998, and the related Letter of Transmittal. The Offer is described in the Tender Offer Statement on Schedule 14D-1 (the "Schedule 14D-1"), as amended, filed by Purchaser and IT with the Securities and Exchange Commission (the "SEC") on January 16, 1998. The Merger Agreement provides that, regardless of whether Shares are accepted for payment or paid for in the Offer, but subject to the satisfaction or waiver of certain conditions precedent (including the approval of the Merger Agreement by holders of a majority of the outstanding Shares), Purchaser will merge with and into OHM (the "Merger"), which will result in OHM becoming a wholly owned subsidiary of IT and the 3 shareholders of OHM receiving consideration consisting primarily of shares of Common Stock of IT ("IT Common Stock"). The Offer and the Merger are more fully described in the Schedule 14D-1. As a prerequisite to the listing on the New York Stock Exchange ("NYSE") of the shares of IT Common Stock to be issued pursuant to the Merger Agreement, the NYSE requires that the issuance of the shares of IT Common Stock pursuant to the Merger Agreement be approved by a majority of the votes cast on the proposal (the "Approval"). Pursuant to the Merger Agreement, the Approval is a condition precedent to the Merger. In connection with the Merger Agreement, IT entered into an Amended and Restated Share Repurchase Agreement, dated as of February 11, 1998 (the "Share Repurchase Agreement"), among IT, Waste Management, Inc., a Delaware corporation ("WMX"), Rust International, Inc., a Delaware corporation ("Rust International"), and Rust Remedial Services Holding Company Inc., a Delaware corporation ("Rust") which, among other things, provides for certain voting arrangements with respect to OHM Common Stock beneficially owned by WMX and Rust. WMX and Rust are the beneficial owners of 10,368,000 shares of Common Stock, including 700,000 currently exercisable warrants held by WMX (the "Warrants"). In addition, in connection with the Merger Agreement, IT entered into a voting agreement, dated as of January 15, 1998 (the "OHM Voting Agreement"), among IT, certain stockholders of OHM (the "OHM Stockholders") and OHM. The OHM Stockholders collectively beneficially own 6,760,513 shares of Common Stock. The Share Repurchase Agreement and OHM Voting Agreement are both described in Item 6. ITEM 5. INTEREST IN SECURITIES OF ISSUER (a) The aggregate number and percentage of Common Stock to which this statement relates is 17,128,513 Shares, representing approximately 57.23% of the Common Stock. (b) Rust, WMX and the OHM Stockholders (collectively, the "Stockholders") have agreed to grant to IT an irrevocable proxy to vote their respective shares of Common Stock in the manner described in the Share Repurchase Agreement and the OHM Voting Agreement (see Item 6). (c) Not applicable. (d) Except as provided in the Share Repurchase Agreement and the OHM Voting Agreement, the Stockholders retain full power to vote and have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, their Common Stock. Below is a list of the Stockholders and the number and percentage of Common Stock they beneficially own. 4
