CLEAN HARBORS, INC. AND SUBSIDIARIES

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

(1) BASIS OF PRESENTATION

The accompanying consolidated interim financial statements include the accounts of Clean Harbors, Inc. and its subsidiaries (collectively, “Clean Harbors” or the “Company”) and have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) and, in the opinion of management, include all adjustments which, except as described elsewhere herein, are of a normal recurring nature, necessary for a fair presentation of the financial position, results of operations, and cash flows for the periods presented. The results for interim periods are not necessarily indicative of results for the entire year. The financial statements presented herein should be read in connection with the financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2009.

The Company’s operations are managed in four segments: Technical Services, Field Services, Industrial Services and Exploration Services. During the quarter ended March 31, 2010, the Company made changes to the composition of these reportable segments. These changes consisted primarily of re-assigning certain departments from the Field Services segment to the Industrial Services segment to align with management reporting changes. The Company has recast the segment information for the three- and nine-month periods ended September 30, 2009 to conform to the current year presentation. See Note 15, “Segment Reporting.”

In preparing the accompanying unaudited consolidated financial statements, the Company has reviewed, as determined necessary by the Company’s management, events that have occurred after September 30, 2010, until the issuance of the financial statements.

(2) SIGNIFICANT ACCOUNTING POLICIES

Concentration of Credit Risk

As a result of the work performed in responding to both the Gulf and Michigan oil spills, one customer individually accounted for greater than 10% of net revenues for the three months ended September 30, 2010, at 11%. No single customer accounted for greater than 10% of net revenues for the nine months ended September 30, 2010. For the three and nine-month periods ended September 30, 2009, no single customer accounted for greater than 10% of net revenues.

Goodwill and Intangible Assets

The Company assesses goodwill for impairment at least on an annual basis as of December 31st by comparing the fair value of each reporting unit to its carrying value. There were no impairment charges during the years ended December 31, 2009, 2008 and 2007. However, as actual results of the Exploration Segment for the first nine months of 2010 were less than originally forecast, the Company performed an interim impairment test for this segment as of September 30, 2010. The Company’s interim test did not result in an impairment charge for the Exploration Segment.

Recent Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board and are adopted by the Company as of the specified effective dates. Unless otherwise discussed below, management believes that the impact of recently issued accounting pronouncements will not have a material impact on the Company’s financial position, results of operations and cash flows, or do not apply to the Company’s operations.

(3) BUSINESS COMBINATIONS

Eveready

On July 31, 2009, the Company acquired 100% of the outstanding common shares of Eveready Inc. (“Eveready”), an Alberta corporation headquartered in Edmonton, Alberta. Eveready provides industrial maintenance and production, lodging, and exploration services to the oil and gas, chemical, pulp and paper, manufacturing and power generation industries.

Table of Contents

During the three months ended June 30, 2010, the Company finalized the purchase accounting for the acquisition of Eveready. No further adjustments have been made to the assets acquired and liabilities assumed since the end of the measurement period. The following table summarizes the recognized amounts of identifiable assets acquired and liabilities assumed at July 31, 2009 (in thousands).

	July 31, 2009 (As adjusted)
Current assets(i)(ii)	$	120,451
Property, plant and equipment	271,752
Identifiable intangible assets(iii)	43,200
Other assets	1,459
Current liabilities(ii)	(39,407		)
Asset retirement obligations	(70		)
Other liabilities	(6,771		)
Noncontrolling interests(iv)	(5,484		)
Total identifiable net assets	$	385,130
Goodwill(v)	24,561
	$	409,691

(i) The final fair value of the financial assets acquired includes customer receivables with a fair value of $80.0 million. The gross amount due is $88.3 million.

(ii) Includes assets and liabilities held for sale of $12.1 million and $3.0 million, respectively.

(iii) The intangible assets are being amortized over a weighted average useful life of 8.2 years.

(iv) The fair value of the noncontrolling interests approximate the maximum redemption prices on the date of the acquisition.

(v) Goodwill, which is attributable to assembled workforce and expected operating and cross-selling synergies, is not expected to be deductible for tax purposes. Goodwill of $12.2 million, $8.4 million, $1.4 million and $2.6 million has been recorded in the Industrial Services, Exploration Services, Field Services and Technical Services segments, respectively.

Sturgeon

On April 30, 2010, the Company acquired privately-held Sturgeon & Son Transportation, Inc. (“Sturgeon”), a wholly-owned subsidiary of Sturgeon Services International, Inc., for a final purchase price of $14.9 million which included $13.0 million in cash (including $0.5 million of post-closing adjustments), $1.0 million related to the issuance of 16,000 shares of the Company’s common stock and $0.9 million related to the buyout of operating leases. Headquartered in Bakersfield, California, Sturgeon specializes in hazardous waste removal and transportation, as well as on-site refinery industrial services. The Company anticipates that this acquisition will enhance its growing West Coast presence in a number of vertical markets including oilfield and refinery services. In addition, Sturgeon operates an extensive fleet of specialized equipment that has been added to the Company’s existing network of assets in the Western U.S.

During the three months ended September 30, 2010, the Company finalized the purchase accounting for the acquisition of Sturgeon. The Company has recorded $4.8 million of property, plant and equipment, $4.0 million of intangible assets that are being amortized over a weighted average useful life of 9 years and $4.6 million of goodwill to the Technical Services segment, based on final fair value estimates. The goodwill is expected to be deductible for tax purposes. Acquisition-related costs of $0.1 million were included in selling, general, and administrative expenses for the nine-month period ended September 30, 2010. No acquisition-related costs were incurred during the three-month period ended September 30, 2010.

(4) FAIR VALUE MEASUREMENTS

The Company’s financial instruments consist of cash and cash equivalents, marketable securities, receivables, trade payables, auction rate securities and long-term debt. The estimated fair value of cash and cash equivalents, receivables, and trade payables approximate their carrying value due to the short maturity of these instruments. As of September 30, 2010, the Company held certain marketable securities and auction rate securities that are required to be measured at fair value on a recurring basis. The fair value of marketable securities is recorded based on quoted market prices. The auction rate securities are classified as available for sale and the fair value of these securities as of September 30, 2010 was estimated utilizing a discounted cash flow analysis. The discounted cash flow analysis considered, among other items, the collateralization underlying the security investments, the creditworthiness of the

Table of Contents

counterparty, the timing of expected future cash flows, and the expectation of the next time these securities are expected to have a successful auction. The auction rate securities were also compared, when possible, to other observable market data with similar characteristics to the securities held by the Company.

As of September 30, 2010, all of the Company’s auction rate securities continue to have AAA underlying ratings. The underlying assets of the Company’s auction rate securities are student loans, which are substantially insured by the Federal Family Education Loan Program. During the three-month period ended June 30, 2010, the Company liquidated $1.3 million in auction rate securities at par. The Company attributes the $0.3 million decline in the fair value of the remaining securities from the original cost basis to external liquidity issues rather than credit issues. The Company assessed the decline in value to be temporary because the Company does not intend to sell the securities at an amount below the original purchase price value and it is more likely than not that it will not have to sell the securities before their maturity or recovery.

During the nine months ended September 30, 2010, the Company recorded an unrealized pre-tax gain on auction rate securities of $0.2 million. As of September 30, 2010, the Company continued to earn interest on its auction rate securities according to their stated terms with interest rates resetting generally every 28 days.

The Company’s assets measured at fair value on a recurring basis subject to the disclosure requirements at September 30, 2010 and December 31, 2009 were as follows (in thousands):

(7) CLOSURE AND POST-CLOSURE LIABILITIES

The changes to closure and post-closure liabilities (also referred to as “asset retirement obligations”) for the nine months ended September 30, 2010 were as follows (in thousands):

	Landfill Retirement Liability			Non-Landfill Retirement Liability			Total
Balance at January 1, 2010	$	28,070		$	7,740		$	35,810
New asset retirement obligations	1,256			—			1,256

Balance at September 30, 2010	$	27,284		$	8,673		$	35,957

Table of Contents

All of the landfill facilities included in the above were active as of September 30, 2010.

New asset retirement obligations incurred in 2010 are being discounted at the credit-adjusted risk-free rate of 9.74% and inflated at a rate of 1.02%.

(8) REMEDIAL LIABILITIES

The changes to remedial liabilities for the nine months ended September 30, 2010 were as follows (in thousands):

	Remedial Liabilities for Landfill Sites			Remedial Liabilities for Inactive Sites			Remedial Liabilities (Including Superfund) for Non-Landfill Operations			Total
Balance at January 1, 2010	$	5,337		$	86,761		$	53,388		$	145,486
Accretion	194			2,963			1,748			4,905
Changes in estimates recorded to statement of income	(8		)	(4,282		)	(948		)	(5,238		)
Settlement of obligations	(88		)	(2,977		)	(2,100		)	(5,165		)
Currency translation and other	43			9			238			290
Balance at September 30, 2010	$	5,478		$	82,474		$	52,326		$	140,278

The benefit resulting from the changes in estimates for remedial liabilities for inactive sites was based primarily on revisions to certain liability estimates due to new site information and the installation of more efficient processing equipment. The benefit resulting from changes in estimates for non-landfill liabilities was primarily due to (i) the discounting effect of delays in certain remedial projects and (ii) the completion of remedial projects at lower than anticipated cost, offset by (iii) new regulatory compliance obligations.

(9) FINANCING ARRANGEMENTS

The following table is a summary of the Company’s financing arrangements (in thousands):

	September 30, 2010			December 31, 2009

Senior secured notes, at 7.625%, due August 15, 2016	$	270,000		$	300,000
Revolving credit facility, due July 31, 2013	—			—
Less unamortized issue discount	(6,201		)	(7,567		)
Long-term obligations	$	263,799		$	292,433

On September 28, 2010, the Company redeemed $30.0 million (10% of the total of $300.0 million then outstanding) of its 7.625% senior secured notes in accordance with the terms of the notes. The notes permit the Company, at any time prior to August 15, 2012, but not more than once in any twelve-month period, to make an optional redemption of up to $30.0 million at a redemption price of 103% of the principal amount, plus accrued interest through the redemption date. In connection with the partial redemption, the Company recorded an aggregate $2.3 million loss on early extinguishment of debt, which consisted of a $0.9 million premium and non-cash expenses of $0.7 million related to unamortized financing costs and $0.7 million of unamortized discount.

Table of Contents

At September 30, 2010, the revolving credit facility had no outstanding loans, $34.0 million available to borrow and $86.0 million of letters of credit outstanding. The fair value of the Company’s outstanding long-term debt is based on quoted market price and was $280.9 million and $294.9 million at September 30, 2010 and December 31, 2009, respectively. The financing arrangements and principal terms of the senior secured notes and the revolving credit facility are discussed further in the Company’s 2009 Annual Report on Form 10-K. There were no material changes in such terms during the first nine months of 2010. Effective October 1, 2010, the interest rate for borrowings under the revolving credit facility was reduced to either, at the Company’s option, (i) LIBOR plus an applicable margin ranging from 2.25% to 2.75% (as compared to 3.25% to 3.75% previously in effect) per annum based on the then level of the Company’s fixed charge coverage ratio or (ii) Bank of America, N.A.’s base rate plus an applicable margin ranging from 1.25% to 1.75% (as compared to 2.25% to 2.75% previously in effect) per annum based on such fixed charge coverage ratio, and the fee for outstanding letters of credit was reduced to the applicable reduced LIBOR margin described above.

(10) HELD FOR SALE

In connection with the Company’s acquisition of Eveready, the Company agreed with the Canadian Commissioner of Competition to divest the Pembina Area Landfill, located near Drayton Valley, Alberta, due to its proximity to the Company’s existing landfill in the region. At the end of April 2010, the Company completed the sale of the Pembina Area Landfill for $11.7 million. In connection with this sale, the Company recognized a pre-tax gain of $1.3 million which has been recorded in income from discontinued operations on the Company’s consolidated statement of income for the nine months ended September 30, 2010. Prior to the sale, the Pembina Area Landfill met the held for sale criteria and the fair value of its assets and liabilities less estimated costs to sell were classified as held for sale in the Company’s consolidated balance sheet. During the period from January 1, 2010 to April 30, 2010, the Pembina Area Landfill recorded $2.2 million of revenues and $2.5 million of pre-tax income (including the pre-tax gain on sale) which are included in income from discontinued operations.

In April 2010 the Company disposed of its mobile industrial health business for $2.4 million and recognized a pre-tax gain of $1.4 million in relation to this sale. The gain was recorded in income from discontinued operations in the Company’s consolidated statement of income. At March 31, 2010, the mobile industrial health business met the held for sale criteria and the fair value of its assets and liabilities less estimated costs to sell were classified as held for sale in the Company’s consolidated balance sheet. Revenues and pre-tax income related to the mobile industrial health business were not material for the period from January 1, 2010 to April 2010.

(11) INCOME TAXES

The Company’s effective tax rate (including taxes on income from discontinued operations) for the three and nine months ended September 30, 2010 was 38.6 percent and 29.1 percent, respectively, compared to 43.6 percent and 43.8 percent, respectively, for the same periods in 2009. The decrease in the effective tax rate for the nine months ended September 30, 2010 was primarily attributable to the decrease in unrecognized tax benefits recorded as a discrete item in the second quarter of 2010. The higher effective tax rate for the three months ended September 30, 2009 as compared to the same period in 2010 was primarily due to the non-deductible acquisition costs related to the acquisition of Eveready recorded in 2009. In addition, the overall decrease in the effective rate for 2010 as compared to 2009 was the result of increased earnings in Canada which has a lower statutory tax rate as compared to the United States.

Total unrecognized tax benefits, other than adjustments for additional accruals for interest and penalties and foreign currency translation, decreased by approximately $14.0 million. The $14.0 million (which included interest and penalties of $5.9 million) was recorded in earnings and therefore impacted the effective income tax rate. Approximately $13.1 million was due to expiring statute of limitation periods related to a historical Canadian business combination and the remaining $0.9 million was related to the conclusion of examinations with state taxing authorities and the expiration of various state statute of limitation periods.

As of September 30, 2010, the Company’s unrecognized tax benefits were $65.6 million, which included $19.0 million of interest and $6.5 million of penalties. As of December 31, 2009, the Company’s unrecognized tax benefits were $76.2 million, which included $21.9 million of interest and $6.1 million of penalties.

Due to expiring statute of limitation periods, the Company anticipates that total unrecognized tax benefits, other than adjustments for additional accruals for interest and penalties and foreign currency translation, will decrease by approximately $0.7 million within the next twelve months. The $0.7 million (which includes interest and penalties of $0.2 million) is related to various state and local jurisdictional tax laws and will be recorded in earnings and therefore will impact the effective income tax rate.

Table of Contents

September 30, 2010 consisted of $9.2 million of foreign tax credits, $0.9 million of state net operating loss carryforwards and less than $0.1 million of foreign net operating loss carryforwards. The allowance as of December 31, 2009 consisted of $9.2 million of foreign tax credits, $0.9 million of state net operating loss carryforwards and $1.1 million of foreign net operating loss carryforwards. The reduction in the valuation allowance was due to the release of foreign net operating loss carryforwards for a dissolved entity.

(12) EARNINGS PER SHARE

The following table sets forth the calculation of the numerator and denominator used in the computation of basic and diluted net income per common share attributable to the Company’s common stockholders for the three- and nine-month periods ended September 30, 2010 and 2009 (in thousands except for per share amounts):

The dilutive effect of all outstanding stock options and restricted stock is included in the above calculations. For the three- and nine-month periods ended September 30, 2010, the above calculation excluded the dilutive effects of 85 thousand outstanding performance stock awards for which the performance criteria were not attained and 18 thousand stock options that were not then in-the-money. For the three- and nine-month periods ended September 30, 2009, the above calculation excluded the dilutive effects of 142 thousand outstanding performance stock awards as the performance criteria were not attained and 18 thousand options that were not then in-the-money, and 32 thousand unvested shares then held in the employee participation plan trust.

(13) STOCK-BASED COMPENSATION

The following table summarizes the total number and type of awards granted during the three- and nine-month periods ended September 30, 2010, as well as the related weighted-average grant-date fair values:

	Three Months Ended September 30, 2010			Nine Months Ended September 30, 2010
	Shares	Weighted- Average Grant-Date Fair Value		Shares	Weighted- Average Grant-Date Fair Value
Restricted stock awards	19,916	$	61.36	54,075	$	58.94

Common stock awards	1,750	$	65.28	1,750	$	65.28
Total awards	22,181			144,246

Certain performance stock awards granted in 2010 are subject to both achieving predetermined revenue and EBITDA targets for a specified period of time and service conditions. As of September 30, 2010, based on year-to-date results of operations, management continued to believe that it was probable that the performance targets will be achieved by December 31, 2010 and as a

result, $1.0 million and $1.7 million of expense was recognized through sales, general and administrative expenses during the three- and nine-month periods ended September 30, 2010, respectively, related to the 2010 performance stock awards.

In regards to the performance awards granted in 2009, prior to the second quarter of 2010, management believed that it was not probable that the performance targets would be achieved and therefore recorded no compensation expense during fiscal 2009 and during the first quarter of 2010. As of June 30, 2010, based on the year-to-date results of operations, management believed that it was probable that the performance targets for the 2009 performance awards will be achieved and recognized $1.3 million of cumulative expense during the second quarter through sales, general and administrative expenses. As of September 30, 2010, management continued to believe that it was probable the performance targets will be achieved and as a result, $0.2 million and $1.5 million of expense was recognized during the three- and nine-month periods ended September 30, 2010, respectively.

(14) COMMITMENTS AND CONTINGENCIES

Legal and Administrative Proceedings

The Company’s waste management services are regulated by federal, state, provincial and local laws enacted to regulate discharge of materials into the environment, remediation of contaminated soil and groundwater or otherwise protect the environment. This ongoing regulation results in the Company frequently becoming a party to legal or administrative proceedings involving all levels of governmental authorities and other interested parties. The issues involved in such proceedings generally relate to applications for permits and licenses by the Company and conformity with legal requirements, alleged violations of existing permits and licenses, or alleged responsibility arising under federal or state Superfund laws to remediate contamination at properties owned either by the Company or by other parties (“third party sites”) to which either the Company or prior owners of certain of the Company’s facilities shipped wastes.

At September 30, 2010 and December 31, 2009, the Company had recorded reserves of $29.4 million and $28.8 million, respectively, in the Company’s financial statements for actual or potential liabilities related to the legal and administrative proceedings in which the Company was then involved, the principal of which are described below. At September 30, 2010 and December 31, 2009, the Company believed that it was reasonably possible that the amount of these potential liabilities could be as much as $3.6 million more and $4.7 million more, respectively. The Company periodically adjusts the aggregate amount of these reserves when these actual or potential liabilities are paid or otherwise discharged, new claims arise, or additional relevant information about existing or potential claims becomes available.

As of September 30, 2010, the principal legal and administrative proceedings in which the Company was involved, or which had been terminated during 2010, were as follows:

Ville Mercier. In September 2002, the Company acquired the stock of a subsidiary (the “Mercier Subsidiary”) which owns a hazardous waste incinerator in Ville Mercier, Quebec (the “Mercier Facility”). The property adjacent to the Mercier Facility, which is also owned by the Mercier Subsidiary, is now contaminated as a result of actions dating back to 1968, when the Government of Quebec issued to a company unrelated to the Mercier Subsidiary two permits to dump organic liquids into lagoons on the property. By 1972, groundwater contamination had been identified, and the Quebec government provided an alternate water supply to the municipality of Ville Mercier.

In 1999, Ville Mercier and three neighboring municipalities filed separate legal proceedings against the Mercier Subsidiary and the Government of Quebec. The lawsuits assert that the defendants are jointly and severally responsible for the contamination of groundwater in the region, which they claim caused each municipality to incur additional costs to supply drinking water for their citizens since the 1970’s and early 1980’s. The four municipalities claim a total of $1.6 million (CDN) as damages for additional costs to obtain drinking water supplies and seek an injunctive order to obligate the defendants to remediate the groundwater in the region. The Quebec Government also sued the Mercier Subsidiary to recover approximately $17.4 million (CDN) of alleged past costs for constructing and operating a treatment system and providing alternative drinking water supplies.

On September 26, 2007, the Quebec Minister of Sustainable Development, Environment and Parks issued a Notice pursuant to Section 115.1 of the Environment Quality Act, superseding Notices issued in 1992, which are the subject of the pending litigation. The more recent Notice notifies the Mercier Subsidiary that, if the Mercier Subsidiary does not take certain remedial measures at the site, the Minister intends to undertake those measures at the site and claim direct and indirect costs related to such measures. The Mercier Subsidiary continues to assert that it has no responsibility for the groundwater contamination in the region and will contest any action by the Ministry to impose costs for remedial measures on the Mercier Subsidiary. The Company also continues to pursue settlement options. At September 30, 2010 and December 31, 2009, the Company had accrued $12.9 million and $12.8 million, respectively, for remedial liabilities relating to the Ville Mercier legal proceedings.

CH El Dorado. In August 2006, the Company purchased all of the outstanding membership interests in Teris LLC (“Teris”) and changed the name of Teris to Clean Harbors El Dorado, LLC (“CH El Dorado”). At the time of the acquisition, Teris was, and CH

Table of Contents

El Dorado now is, involved in certain legal proceedings arising from a fire on January 2, 2005, at the incineration facility owned and operated by Teris in El Dorado, Arkansas.

CH El Dorado is defending vigorously the claims asserted against Teris in those proceedings, and the Company believes that the resolution of those proceedings will not have a material adverse effect on the Company’s financial position, results of operations or cash flows. In addition to CH El Dorado’s defenses to the lawsuits, the Company will be entitled to rely upon an indemnification from the seller of the membership interests in Teris which is contained in the purchase agreement for those interests. Under that agreement, the seller agreed to indemnify (without any deductible amount) the Company against any damages which the Company might suffer as a result of the lawsuits to the extent that such damages are not fully covered by insurance or the reserves which Teris had established on its books prior to the acquisition. The seller’s parent also guaranteed the indemnification obligation of the seller to the Company.

Deer Trail, Colorado Facility. Since April 5, 2006, the Company has been involved in various legal proceedings which have arisen as a result of the issuance by the Colorado Department of Public Health and Environment (“CDPHE”) of a radioactive materials license (“RAD License”) to a Company subsidiary, Clean Harbors Deer Trail, LLC (“CHDT”) to accept certain low level radioactive materials known as “NORM/TENORM” wastes for disposal. Adams County, the county where the CHDT facility is located, filed two suits against the CDPHE in Colorado effectively seeking to invalidate the license. The two suits filed in 2006 were both dismissed and those dismissals were upheld by the Colorado Court of Appeals. Adams County appealed those rulings to the Colorado Supreme Court which ruled on October 13, 2009 on the procedural issue that the County did have standing to challenge the license in district court and remanded the case back to that court for further proceedings. Adams County filed a third suit directly against CHDT in 2007 again attempting to invalidate the license. That suit was dismissed on November 14, 2008, and Adams County has now appealed that dismissal to the Colorado Court of Appeals. The Company continues to believe that the grounds asserted by the County are factually and legally baseless and has contested the appeal vigorously. The Company has not recorded any liability for this matter on the basis that such liability is currently neither probable nor estimable.

Superfund Proceedings

The Company has been notified that either the Company or the prior owners of certain of the Company’s facilities for which the Company may have certain indemnification obligations have been identified as potentially responsible parties (“PRPs”) or potential PRPs in connection with 62 sites which are subject to or are proposed to become subject to proceedings under federal or state Superfund laws. Of the 62 sites, two involve facilities that are now owned by the Company and 60 involve third party sites to which either the Company or the prior owners shipped wastes. In connection with each site, the Company has estimated the extent, if any, to which it may be subject, either directly or as a result of any such indemnification provisions, for cleanup and remediation costs, related legal and consulting costs associated with PRP investigations, settlements, and related legal and administrative proceedings. The amount of such actual and potential liability is inherently difficult to estimate because of, among other relevant factors, uncertainties as to the legal liability (if any) of the Company or the prior owners of certain of the Company’s facilities to contribute a portion of the cleanup costs, the assumptions that must be made in calculating the estimated cost and timing of remediation, the identification of other PRPs and their respective capability and obligation to contribute to remediation efforts, and the existence and legal standing of indemnification agreements (if any) with prior owners, which may either benefit the Company or subject the Company to potential indemnification obligations.

The Company’s potential liability for cleanup costs at the two facilities now owned by the Company and at 35 (the “Listed Third Party Sites”) of the 60 third party sites arose out of the Company’s 2002 acquisition of substantially all of the assets (the “CSD assets”) of the Chemical Services Division of Safety-Kleen Corp. As part of the purchase price for the CSD assets, the Company became liable as the owner of these two facilities and also agreed to indemnify the prior owners of the CSD assets against their share of certain cleanup costs for the Listed Third Party Sites payable to governmental entities under federal or state Superfund laws. Of the 35 Listed Third Party Sites, 17 are currently requiring expenditures on remediation including one site that the Company is contesting the extent of the prior owner’s liability with the PRP group, ten are now settled, and eight are not currently requiring expenditures on remediation. The status of the two facilities owned by the Company (the Wichita Property and the BR Facility) and two of the Listed Third Party Sites (the Breslube-Penn and Casmalia sites) are further described below. There are also three third party sites at which the Company has been named a PRP as a result of its acquisition of the CSD assets but disputes that it has any cleanup or related liabilities: one such site (the Marine Shale site) is described below. The Company views any liabilities associated with the Marine Shale site and the other two sites as excluded liabilities under the terms of the CSD asset acquisition, but the Company is working with the EPA on a potential settlement. In addition to the CSD related Superfund sites, there are certain of the other third party sites which are not related to the Company’s acquisition of the CSD assets, and certain notifications which the Company has received about other third party sites.

Wichita Property. The Company acquired in 2002 as part of the CSD assets a service center located in Wichita, Kansas (the “Wichita Property”). The Wichita Property is one of several properties located within the boundaries of a 1,400 acre state-designated

Table of Contents

Superfund site in an old industrial section of Wichita known as the North Industrial Corridor Site. Along with numerous other PRPs, the former owner executed a consent decree relating to such site with the EPA, and the Company is continuing its ongoing remediation program for the Wichita Property in accordance with that consent decree. The Company also acquired rights under an indemnification agreement between the former owner and an earlier owner of the Wichita Property, which the Company anticipates but cannot guarantee will be available to reimburse certain such cleanup costs.

BR Facility. The Company acquired in 2002 as part of the CSD assets a former hazardous waste incinerator and landfill in Baton Rouge (the “BR Facility”), for which operations had been previously discontinued by the prior owner. In September 2007, the United States Environmental Protection Agency (the “EPA”) issued a special notice letter to the Company related to the Devil’s Swamp Lake Site (“Devil’s Swamp”) in East Baton Rouge Parish, Louisiana. Devil’s Swamp includes a lake located downstream of an outfall ditch where wastewater and stormwater have been discharged, and Devil’s Swamp is proposed to be included on the National Priorities List due to the presence of Contaminants of Concern (“COC”) cited by the EPA. These COCs include substances of the kind found in wastewater and storm water discharged from the BR Facility in past operations. The EPA originally requested COC generators to submit a good faith offer to conduct a remedial investigation feasibility study directed towards the eventual remediation of the site. The Company is currently performing corrective actions at the BR Facility under an order issued by the Louisiana Department of Environmental Quality (the “LDEQ”), and has begun conducting the remedial investigation and feasibility study under an order issued by the EPA. The Company cannot presently estimate the potential additional liability for the Devil’s Swamp cleanup until a final remedy is selected by the EPA.

Breslube-Penn Site. At one of the 35 Listed Third Party Sites, the Breslube-Penn site, the EPA brought suit in 1997 in the U.S. District Court for the Western District of Pennsylvania against a large number of PRPs for recovery of the EPA’s response costs in connection with that site. The named defendants are alleged to be jointly and severally liable for the remediation of the site and all response costs associated with the site. One of the prior owners, GSX Chemical Services of Ohio (“GSX”), was a named defendant in the original complaint. In 2006, the EPA filed an amended complaint naming the Company as defendant, alleging that the Company was the successor in interest to the liability of GSX. The Company has reached an agreement in principle with the EPA and the PRP group that will be cleaning up the site, and expects to execute the final settlement documents in the next quarter of this year.

Casmalia Site. At one of the 35 Listed Third Party Sites, the Casmalia Resources Hazardous Waste Management Facility (the “Casmalia site”) in Santa Barbara County, California, the Company received from the EPA a request for information in May 2007. In that request, the EPA is seeking information about the extent to which, if at all, the prior owner transported or arranged for disposal of waste at the Casmalia site. The Company has not recorded any liability for this 2007 notice on the basis that such transporter or arranger liability is currently neither probable nor estimable.

Marine Shale Site. Prior to 1996, Marine Shale Processors, Inc. (“Marine Shale”) operated a kiln in Amelia, Louisiana which incinerated waste producing a vitrified aggregate as a by-product. Marine Shale contended that its operation recycled waste into a useful product, i.e., vitrified aggregate, and therefore was exempt from regulation under the RCRA and permitting requirements as a hazardous waste incinerator under applicable federal and state environmental laws. The EPA contended that Marine Shale was a “sham-recycler” subject to the regulation and permitting requirements as a hazardous waste incinerator under RCRA, that its vitrified aggregate by-product was a hazardous waste, and that Marine Shale’s continued operation without required permits was illegal. Litigation between the EPA and Marine Shale began in 1990 and continued until July 1996, when the U.S. Fifth Circuit Court of Appeals ordered Marine Shale to shut down its operations.

On May 11, 2007, the EPA and the LDEQ issued a special notice to the Company and other PRPs, seeking a good faith offer to address site remediation at the former Marine Shale facility. Certain of the former owners of the CSD assets were major customers of Marine Shale, but the Marine Shale site was not included as a Listed Third Party Site in connection with the Company’s acquisition of the CSD assets and the Company was never a customer of Marine Shale. Although the Company believes that it is not liable (either directly or under any indemnification obligation) for cleanup costs at the Marine Shale site, the Company elected to join with other parties which had been notified that are potentially PRPs in connection with Marine Shale site to form a group (the “Site Group”) to retain common counsel and participate in further negotiations with the EPA and the LDEQ directed towards the eventual remediation of the Marine Shale site.

The Site Group made a good faith settlement offer to the EPA on November 29, 2007, and negotiations among the EPA, the LDEQ and the Site Group with respect to the Marine Shale site are ongoing. At September 30, 2010 and December 31, 2009, the amount of the Company’s remaining reserves relating to the Marine Shale site was $3.8 million and $3.7 million, respectively.

Certain Other Third Party Sites. At 14 of the 60 third party sites, the Company has an indemnification agreement with ChemWaste, a former subsidiary of Waste Management, Inc. and the prior owner. The agreement indemnifies the Company with respect to any liability at the 14 sites for waste disposed prior to the Company’s acquisition of the sites. Accordingly, Waste Management is paying all costs of defending those subsidiaries in those 14 cases, including legal fees and settlement costs. However,

there can be no guarantee that the Company’s ultimate liabilities for these sites will not exceed the amount recorded or that indemnities applicable to any of these sites will be available to pay all or a portion of related costs. The Company does not have an indemnity agreement with respect to any of the other remaining 60 third party sites not discussed above. However, the Company believes that its additional potential liability, if any, to contribute to the cleanup of such remaining sites will not, in the aggregate, exceed $100,000.

Other Notifications. Between September 2004 and May 2006, the Company also received notices from certain of the prior owners of the CSD assets seeking indemnification from the Company at five third party sites which are not included in the third party sites described above that have been designated as Superfund sites or potential Superfund sites and for which those prior owners have been identified as PRPs or potential PRPs. The Company has responded to such letters asserting that the Company has no obligation to indemnify those prior owners for any cleanup and related costs (if any) which they may incur in connection with these five sites. The Company intends to assist those prior owners by providing information that is now in the Company’s possession with respect to those five sites and, if appropriate to participate in negotiations with the government agencies and PRP groups involved. The Company has also investigated the sites to determine the existence of potential liabilities independent from the liability of those former owners, and concluded that at this time the Company is not liable for any portion of the potential cleanup of the five sites and therefore has not established a reserve.

Federal and State Enforcement Actions

From time to time, the Company pays fines or penalties in regulatory proceedings relating primarily to waste treatment, storage or disposal facilities. As of September 30, 2010, there were two proceedings for which the Company reasonably believes that the sanctions could equal or exceed $100,000. During the second quarter, the Company settled one matter involving one of its operating subsidiaries with no material impact to the Company’s financial results of operations. The Company does not believe that the fines or other penalties in these or any of the other regulatory proceedings will, individually or in the aggregate, have a material adverse effect on its financial condition or results of operations.

Guarantees

Each Participant in the Eveready Employee Participation Plan (the “Plan”) described in Note 16, “Stock-Based Compensation and Employee Participation Plan,” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2009, had the option to finance the acquisition of Purchased Units either through the employee’s own funds or a Bank of Montreal (“BMO”) loan to the Participant secured by both the Purchased and Matching Units. Because of the decline in the market value of the predecessor’s units and of Eveready shares subsequent to the purchase by the Participants of the Purchased Units, Eveready subsequently provided to BMO a guarantee of the BMO loans in the maximum amount at September 30, 2010 of CDN $4.7 million (plus interest and collection costs). At September 30, 2010, the aggregate amount of such guarantee, after giving effect to the market value on that date of the Company’s shares derived from the Purchased and Matching Units which secure the BMO loans, was CDN $1.0 million. At September 30, 2010, the Company had accrued CDN $0.5 million related to such guarantee. As described in Note 16, “Stock-Based Compensation and Employee Participation Plan,” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2009, the Company has agreed with certain of its employees who were Participants in the Plan to pay on December 31, 2011 to those employees a cash bonus (a “Shortfall Bonus”) under certain circumstances; the maximum amount of the potential Shortfall Bonus as of September 30, 2010 was $3.1 million. To the extent, if any, that the Company becomes obligated to pay on December 31, 2011 a Shortfall Bonus to any employees who then have outstanding balances in their respective BMO loans, the amount of such Shortfall Bonus (net of withholding taxes) shall first be applied against such outstanding BMO loan balances, thereby decreasing the amount, if any, which the Company might be obligated to pay directly to BMO under the guarantee which Eveready provided to BMO on the BMO loans.

The Company has provided a guarantee to a certain financial institution for financing obtained by a contractor to purchase specific service and automotive equipment in supplying services to the Company. As of September 30, 2010, the total balance of all outstanding third party payments guaranteed by the Company was CDN $0.6 million. The financing is collateralized by the specific equipment purchased and is due to mature between 2010 and 2011. The Company would be required to settle the guarantee if the contractor were to default on the obligation and the collateral held by the financial institution was not sufficient to repay the balance due.

(15) SEGMENT REPORTING

The Company has four reportable segments consisting of Technical Services, Field Services, Industrial Services and Exploration Services. Performance of the segments is evaluated on several factors, of which the primary financial measure is “Adjusted EBITDA,” which consists of net income plus accretion of environmental liabilities, depreciation and amortization, net interest expense, and provision for income taxes. Also excluded are other income and income from discontinued operations, net of tax as these amounts are not considered part of usual business operations. Transactions between the segments are accounted for at the

Table of Contents

Company’s estimate of fair value based on similar transactions with outside customers. During the quarter ended March 31, 2010, the Company made changes to the composition of the reportable segments. These changes consisted primarily of re-assigning certain departments from the Field Services segment to the Industrial Services segment to align with management reporting changes. The Company has reflected the impact of the change in its segment reporting in all periods presented to provide financial information that consistently reflects the Company’s current approach to managing the operations.

The operations not managed through the Company’s four operating segments are recorded as “Corporate Items.” Corporate Items revenues consist of two different operations for which the revenues are insignificant. Corporate Items cost of revenues represents certain central services that are not allocated to the four operating segments for internal reporting purposes. Corporate Items selling, general and administrative expenses include typical corporate items such as legal, accounting and other items of a general corporate nature that are not allocated to the Company’s four operating segments.

The following table reconciles third party revenues to direct revenues for the three- and nine-month periods ended September 30, 2010 and 2009 (in thousands). Third party revenue is revenue billed to outside customers by a particular segment. Direct revenue is the revenue allocated to the segment performing the provided service. The Company analyzes results of operations based on direct revenues because the Company believes that these revenues and related expenses best reflect the manner in which operations are managed.

General

We are a leading provider of environmental, energy and industrial services throughout North America. We serve over 50,000 customers, including a majority of Fortune 500 companies, thousands of smaller private entities and numerous federal, state, provincial and local governmental agencies. We have more than 175 locations, including over 50 waste management facilities, throughout North America in 36 U.S. states, seven Canadian provinces, Mexico and Puerto Rico. We also operate international locations in Bulgaria, China, Singapore, Sweden, Thailand and the United Kingdom.

We report the business in four operating segments consisting of:

· Technical Services — provide a broad range of hazardous material management services including the packaging, collection, transportation, treatment and disposal of hazardous and non-hazardous waste at Company owned incineration, landfill, wastewater, and other treatment facilities.

· Field Services — provide a wide variety of environmental cleanup services on customer sites or other locations on a scheduled or emergency response basis including tank cleaning, decontamination, remediation, and spill cleanup.

· Industrial Services — provide industrial and specialty services, such as high-pressure and chemical cleaning, catalyst handling, decoking, material processing and industrial lodging services to refineries, chemical plants, pulp and paper mills, and other industrial facilities.

· Exploration Services — provide exploration and directional boring services to the energy sector serving oil and gas exploration, production, and power generation.

Technical Services and Field Services are included as part of Clean Harbors Environmental Services, and Industrial Services and Exploration Services are included as part of Clean Harbors Energy and Industrial Services.

Overview

During the three months ended September 30, 2010, our revenues increased 60% to $487.7 million, compared with $305.6 million during the three months ended September 30, 2009. This year-over-year revenue growth was primarily due to our acquisition of Eveready Inc. (“Eveready”) in July 2009, our emergency response to the Gulf of Mexico and Michigan oil spills, and performance in our legacy Clean Harbors business. Our revenues were also favorably impacted by $4.8 million due to the strengthening of the Canadian dollar. Our Energy and Industrial Services business, which is primarily made up of the legacy Eveready business, benefited from increased activity in the oil sands region, refinery turnaround work and high utilization rates at our camps in our lodging business during the quarter.

Table of Contents

Our participation in oil spill response efforts in both the Gulf of Mexico and Michigan generated third party revenues for the quarter of $123.8 million accounting for approximately 25% of total revenues. Over the course of the third quarter, our work in the Gulf of Mexico evolved. At the height of the event in the second quarter, we had more than 3,500 response-related personnel working in the region, consisting of our own employees and a temporary workforce that our subcontractors recruited from the affected areas. By the end of the third quarter, the number of response-related personal was closer to 500.

Our oil spill work in Michigan began in late July and consisted of us supplying a broad array of equipment and experienced personnel. During the quarter our spill-related headcount went as high as 450. The bulk of the primary containment and clean-up work has been completed.

In our Technical Services segment, we achieved year-over-year growth of 5%. Incinerator utilization increased to 91% for the three months ended September 30, 2010, compared to 89% in the same three months in 2009. On a geographic basis, this increase in utilization was driven by our Canadian incineration facilities, which achieved 99% utilization in the quarter. The utilization at our U.S. locations was 87% for the quarter primarily due to a lengthy outage for planned maintenance at Deer Park, which is our largest U.S. facility. Landfill volumes increased 23% year-over-year.

Our Field Services revenues accounted for 36% of our total third quarter revenues due primarily to the oil spill response efforts in the Gulf of Mexico and Michigan. Margins in this segment improved due in part to this emergency response work. Excluding the effect of the oil spills, direct revenues for Field Services increased from the third quarter of 2009, driven primarily by a continuation of routine maintenance and remedial work that had been deferred during the economic recession.

Our Industrial Services revenues accounted for 24% of our total third quarter revenues. The year-over-year increase of 61.4% was primarily due to three full months of revenues compared to two months of revenues in the prior year third quarter. Revenues attributable to the Industrial Services segment were recorded for two months during the quarter ended September 30, 2009, as the Eveready acquisition was consummated on July 31, 2009. Additionally, revenues in this segment increased due to increased activity in transport and our downhole business, continued elevation of oil extraction investment in the Oil Sands region, refinery turnaround work and high utilization rates at our camps in our lodging business. Margins for this business benefited from our continued integration efforts.

Our Exploration Services revenues accounted for 2% of our total third quarter revenues. The year-over-year increase of 14.2% was primarily due to three full months of revenues being compared to two months of revenues in the prior year third quarter. Revenues attributable to the Exploration Services segment were recorded for two months during the quarter ended September 30, 2009, as the Eveready acquisition was consummated on July 31, 2009. Given the warmer summer temperatures and the lack of frozen ground needed to reach remote locations, the third quarter is seasonally the weakest operating quarter. The depressed price of natural gas also continues to limit the current performance of this segment.

Our costs of revenues increased from $210.9 million in the third quarter of 2009 to $335.3 million in the third quarter of 2010. This increase in expenses was primarily due to the acquisition of Eveready, expenses associated with the oil spill response efforts in the Gulf of Mexico and Michigan and increased revenues in the legacy Clean Harbors business. The costs were also impacted by our continued initiative to actively manage our costs, our continued achievement of Eveready synergies, and specific cost cutting measures initiated as a response to the current economic environment. Our gross profit margin was 31.2% for the three months ended September 30, 2010, compared to 31.0% for the same period ended September 30, 2009. The year-over-year slight increase in gross margin resulted from the seasonal strength of our environmental business, as well as the value of our emergency response efforts in the Gulf and Michigan, offset partially by significant top-line contribution of our Industrial Services business, which generates a lower gross margin than our legacy Clean Harbors business.

During the third quarter, our net income was also affected by the recording of a $2.3 million loss on the extinguishment of debt for the repayment of $30.0 million of the Company’s $300.0 million then outstanding senior secured notes.

Environmental Liabilities

We have accrued environmental liabilities as of September 30, 2010, of approximately $176.2 million, substantially all of which we assumed as part of our acquisitions of the Chemical Services Division, or “CSD,” of Safety-Kleen Corp. in 2002, Teris LLC in 2006, and one of the two solvent recycling facilities we purchased from Safety-Kleen Systems, Inc. in 2008. We anticipate such liabilities will be payable over many years and that cash flows generated from operations will be sufficient to fund the payment of such liabilities when required. However, events not now anticipated (such as future changes in environmental laws and regulations) could require that such payments be made earlier or in greater amounts than currently anticipated.

Table of Contents

We realized a net benefit in the nine months ended September 30, 2010, of $5.3 million related to changes in our environmental liability estimates. Changes in environmental liability estimates include changes in landfill retirement liability estimates, which are recorded in cost of revenues, and changes in non-landfill retirement and remedial liability estimates, which are recorded in selling, general, and administrative costs. During the nine months ended September 30, 2010, a benefit of approximately $0.1 million was recorded in cost of revenues and a benefit of approximately $5.2 million was recorded in selling, general and administrative expenses. See further detail discussed in Note 7, “Closure and Post-Closure Liabilities,” and Note 8, “Remedial Liabilities,” to our consolidated financial statements included in Item 1 of this report.

Results of Operations

The following table sets forth for the periods indicated certain operating data associated with our results of operations. This table and subsequent discussions should be read in conjunction with Item 6, “Selected Financial Data,” and Item 8, “Financial Statements and Supplementary Data,” of our Annual Report on Form 10-K for the year ended December 31, 2009 and Item 1, “Financial Statements,” in this report.

Earnings before Interest, Taxes, Depreciation and Amortization (“Adjusted EBITDA”)

We define Adjusted EBITDA (a measure not defined under generally accepted accounting principles) as net income plus accretion of environmental liabilities, depreciation and amortization, net interest expense, other income, provision for income taxes, and income from discontinued operations, net of tax. Our management considers Adjusted EBITDA to be a measurement of performance which provides useful information to both management and investors. Adjusted EBITDA should not be considered an alternative to net income or other measurements under generally accepted accounting principles in the United States (“GAAP”). Because Adjusted EBITDA is not calculated identically by all companies, our measurements of Adjusted EBITDA may not be comparable to similarly titled measures reported by other companies.

We use Adjusted EBITDA to enhance our understanding of our core operating performance, which represents our views concerning our performance in the ordinary, ongoing and customary course of our operations. We historically have found it helpful, and believe that investors have found it helpful, to consider an operating measure that excludes expenses such as debt extinguishment and related costs relating to transactions not reflective of our core operations.

The information about our core operating performance provided by this financial measure is used by our management for a variety of purposes. We regularly communicate Adjusted EBITDA results to our board of directors and discuss with the board our interpretation of such results. We also compare our Adjusted EBITDA performance against internal targets as a key factor in determining cash bonus compensation for executives and other employees, largely because we believe that this measure is indicative of how the fundamental business is performing and is being managed.

Table of Contents

We also provide information relating to our Adjusted EBITDA so that analysts, investors and other interested persons have the same data that we use to assess our core operating performance. We believe that Adjusted EBITDA should be viewed only as a supplement to the GAAP financial information. We also believe, however, that providing this information in addition to, and together with, GAAP financial information permits the foregoing persons to obtain a better understanding of our core operating performance and to evaluate the efficacy of the methodology and information used by management to evaluate and measure such performance on a standalone and a comparative basis.

Segment data

Performance of our segments is evaluated on several factors of which the primary financial measure is Adjusted EBITDA. The following tables set forth certain operating data associated with our results of operations and summarizes Adjusted EBITDA contribution by operating segment for the three and nine months ended September 30, 2010 and 2009. We consider the Adjusted EBITDA contribution from each operating segment to include revenue attributable to each segment less operating expenses, which include cost of revenues and selling, general and administrative expenses. Revenue attributable to each segment is generally external or direct revenue from third party customers. Certain income or expenses of a non-recurring or unusual nature are not included in the operating segment Adjusted EBITDA contribution. Amounts presented have been recast to reflect the changes made to our segment presentation in the quarter ended March 31, 2010 as a result of the changes made in the composition of the reportable segments. These changes consisted primarily of re-assigning certain departments from the Field Services segment to the Industrial Services segment to

Revenues

Technical Services revenues increased 5.1%, or $9.0 million, in the three months ended September 30, 2010 from the comparable period in 2009 primarily due to increases in volumes being processed through our landfills, treatment, storage and disposal facilities and waste water treatment plants ($3.8 million), an increase due to the integration of the Eveready business into the Technical Services segment ($1.5 million), and strengthening of the Canadian dollar ($1.7 million). These increases were partially offset by reductions due to changes in product mix and reductions in pricing ($2.2 million) and reductions in volumes being processed through our incinerators and our solvent recycling facilities ($1.8 million). The remaining increase related primarily to growth in our base business.

Field Services revenues increased 257.7%, or $126.8 million, in the three months ended September 30, 2010 from the comparable period in 2009. Field Services performed oil spill project business in both the Gulf of Mexico and Michigan during the three months ended September 30, 2010 which accounted for $123.8 million of our third party revenues. Excluding those oil spill projects, Field Services revenues increased for the three months ended September 30, 2010 from the comparable period in 2009 primarily due to increases in our polychlorinated biphenyls (“PCB”) business ($1.2 million), increases in our oil recycling business due to increased pricing and volumes ($0.8 million), and strengthening of the Canadian dollar ($0.3 million), offset partially by decreases in large remedial project business ($1.3 million). The remaining increase related primarily to growth in our base business.

Industrial Services revenues increased 61.4%, or $45.4 million, in the three months ended September 30, 2010 from the comparable period in 2009 primarily due to three full months of revenues compared to two months of revenues in the prior year third quarter. Revenues attributable to the Industrial Services segment were recorded for two months during the quarter ended September 30, 2009, as the Eveready acquisition was consummated on July 31, 2009. Additionally, revenues in this segment increased due primarily to activity in the oil sands region, refinery turnaround work and high utilization rates at our camps in our lodging business, as well as strengthening of the Canadian dollar ($2.4 million).

Exploration Services revenues increased 14.2%, or $1.2 million, in the three months ended September 30, 2010 from the comparable period in 2009 primarily due to three full months of revenues compared to two months of revenues in the prior year third quarter. Revenues attributable to the Exploration Services segment were recorded for two months during the quarter ended September 30, 2009, as the Eveready acquisition was consummated on July 31, 2009. In addition, revenues in this segment increased due to strengthening of the Canadian dollar ($0.3 million).

There are many factors which have impacted, and continue to impact, our revenues. These factors include, but are not limited to: the level of emergency response projects, the general conditions of the oil and gas industries particularly in the Alberta oil sands and other parts of Western Canada, competitive industry pricing, and the effects of fuel prices on our fuel recovery fees.

Cost of Revenues

Technical Services cost of revenues increased 8.7%, or $9.7 million, in the three months ended September 30, 2010 from the comparable period in 2009 primarily due to increases in salary and labor expenses ($2.6 million), materials and supplies expenses ($1.2 million), fuel expense ($1.0 million), chemicals and consumables expenses ($0.8 million), utilities costs ($0.6 million), outside transportation costs ($0.5 million), equipment rental fees ($0.5 million), year-over-year unfavorable changes in environmental liability estimates ($0.1 million), and strengthening of the Canadian dollar ($0.8 million).

Field Services cost of revenues increased 226.0%, or $82.3 million, in the three months ended September 30, 2010 from the comparable period in 2009 primarily due to increased subcontractor fees, materials and supplies costs, equipment rental costs and travel and other costs associated with the oil spill project business in both the Gulf of Mexico and Michigan of $74.4 million, or 62.7% of total Field Services cost of revenues. Excluding those oil spill projects, Field Services cost of revenues increased $7.9 million, or 21.6%, for the three months ended September 30, 2010 from the comparable period in 2009 primarily due to increases in labor and related expenses ($3.1 million), materials for reclaim or resale ($1.5 million), subcontractor costs ($1.4 million), equipment rental ($0.5 million), materials and supplies costs ($0.5 million) and fuel costs ($0.4 million), and strengthening of the Canadian dollar ($0.2 million).

Industrial Services cost of revenues increased 56.7%, or $32.0 million, in the three months ended September 30, 2010 from the comparable period in 2009 primarily due to three full months cost of revenues compared to two months cost of revenues in the prior year third quarter. Costs in this segment increased in proportion to revenues primarily related to increased catering costs associated with the increased lodging services revenues, higher subcontractor fees, equipment rental costs and travel costs related to the shutdown activity, and strengthening of the Canadian dollar ($1.8 million).

Exploration Services cost of revenues increased 2.7%, or $0.2 million, in the three months ended September 30, 2010 from the comparable period in 2009 primarily due to three full months cost of revenues compared to two months cost of revenues in the prior year third quarter.

We believe that our ability to manage operating costs is important in our ability to remain price competitive. We continue to upgrade the quality and efficiency of our waste treatment services through the development of new technology and continued modifications and upgrades at our facilities, and implementation of strategic sourcing initiatives. We plan to continue to focus on achieving cost savings relating to purchased goods and services through a strategic sourcing initiative. No assurance can be given that our efforts to reduce future operating expenses will be successful.

Revenues

Technical Services revenues increased 4.6%, or $23.0 million, in the nine months ended September 30, 2010 from the comparable period in 2009 primarily due to increases in volumes being processed through all our facilities ($10.0 million), an increase due to the integration of the Eveready business into the Technical Services segment ($5.9 million), and strengthening of the Canadian dollar ($9.6 million). These increases were partially offset by reductions due to changes in product mix and reductions in pricing ($16.9 million). The remaining increase related primarily to growth in our base business.

Field Services revenues increased 186.9%, or $247.5 million, in the nine months ended September 30, 2010 from the comparable period in 2009. Field Services performed oil spill project business in both the Gulf of Mexico and Michigan during the nine months ended September 30, 2010 which accounted for $232.4 million of our third party revenues. Excluding those oil spill projects, Field Services revenues increased for the nine months ended September 30, 2010 from the comparable period in 2009 primarily due to recording nine full months of revenues compared to two months of revenues in the prior year nine months for Field Service business that was formerly Eveready ($5.6 million), increases in our PCB business ($4.3 million), increases in large remedial project business ($3.5 million), increases in our oil recycling business due to increased pricing and volumes ($2.7 million), and strengthening of the Canadian dollar ($1.2 million).

Industrial Services revenues increased 312.8%, or $291.9 million, in the nine months ended September 30, 2010 from the comparable period in 2009 primarily due to nine full months of revenues compared to two months of revenues in the nine months ended September 30, 2009. Additionally, revenues in this segment increased primarily due to activity in the oil sands region, refinery turnaround work and high utilization rates at our camps in our lodging business, as well as strengthening of the Canadian dollar ($2.9 million).

Exploration Services revenues increased 296.1%, or $24.7 million, in the nine months ended September 30, 2010 from the comparable period in 2009 primarily due to nine full months of revenues compared to two months of revenues in the nine months

ended September 30, 2009. Additionally, revenues in this segment increased due to strengthening of the Canadian dollar ($0.4 million).

There are many factors which have impacted, and continue to impact, our revenues. These factors include, but are not limited to: the level of emergency response projects, the effects of unseasonable weather conditions in the first quarter, the general conditions of the oil and gas industries particularly in the Alberta oil sands and other parts of Western Canada, competitive industry pricing, and the effects of fuel prices on our fuel recovery fees.

Cost of Revenues

Technical Services cost of revenues increased 8.0%, or $25.5 million, in the nine months ended September 30, 2010 from the comparable period in 2009 primarily due to increases in salary and labor expenses ($9.1 million), vehicle expenses and equipment repairs ($2.6 million), outside transportation costs ($2.1 million), fuel expense ($1.9 million), materials and supplies expenses ($1.9 million), utilities costs ($1.8 million), materials for reclaim costs ($1.2 million), year-over-year unfavorable changes in environmental liability estimates ($0.7 million), and strengthening of the Canadian dollar ($5.2 million), offset partially by reduced outside disposal and rail fees ($1.3 million).

Field Services cost of revenues increased 158.5%, or $160.6 million, in the nine months ended September 30, 2010 from the comparable period in 2009 primarily due to increased subcontractor fees, materials and supplies costs, equipment rental costs and travel and other costs associated with the oil spill project business in the Gulf of Mexico and Michigan of $139.9 million, or 53.4% of total Field Services cost of revenues. Excluding those oil spill projects, Field Services cost of revenues increased $20.6 million, or 20.3%, for the nine months ended September 30, 2010 from the comparable period in 2009 primarily due to increases in labor and related expenses ($6.0 million), materials for reclaim or resale ($3.8 million), subcontractor costs ($2.6 million), fuel costs ($1.3 million), materials and supplies costs ($1.3 million), equipment rental ($1.1 million) and travel costs ($0.9 million), and strengthening of the Canadian dollar ($1.0 million).

Industrial Services cost of revenues increased 302.9%, or $215.5 million, in the nine months ended September 30, 2010 from the comparable period in 2009 primarily due to nine full months cost of revenues compared to two months cost of revenues in the nine months ended September 30, 2009. Costs in this segment increased in proportion to revenues primarily related to increased catering costs associated with the increased lodging services revenues, higher subcontractor fees, equipment rental costs and travel costs related to the shutdown activity, and strengthening of the Canadian dollar ($2.2 million).

Exploration Services cost of revenues increased 258.9%, or $16.9 million, in the nine months ended September 30, 2010 from the comparable period in 2009 primarily due to nine full months cost of revenues compared to two months of cost of revenues in the nine months ended September 30, 2009. Additionally, costs in this segment increased due to increased fuel prices and travel costs, as well as strengthening of the Canadian dollar (0.3 million).

Corporate Items cost of revenues increased $0.9 million for the nine months ended September 30, 2010, as compared to the same period in 2009 primarily due to increased labor costs ($2.0 million), insurance costs ($0.8 million) and fuel, travel and other costs ($0.4 million), offset by a reduction in health insurance related costs ($2.4 million).

Selling, General and Administrative Expenses

Technical Services selling, general and administrative expenses increased 0.4%, or $0.2 million, in the nine months ended September 30, 2010 from the comparable period in 2009 primarily due to increased salaries, commissions and bonuses offset partially by year-over-year favorable changes in environmental liability estimates.

Field Services selling, general and administrative expenses increased 28.7%, or $4.6 million, in the nine months ended September 30, 2010 from the comparable period in 2009 primarily due to an increase in commissions and bonus expense.

Industrial Services selling, general and administrative expenses increased 125.8%, or $12.0 million, in the nine months ended September 30, 2010 from the comparable period in 2009 primarily due to the impact of nine full months of expenses compared to two months of expenses in the nine months ended September 30, 2009.

Table of Contents

Exploration Services selling, general and administrative expenses decreased 75.3%, or $0.6 million, in the nine months ended September 30, 2010 from the comparable period in 2009 primarily due to the recovery of $2.2 million of pre-acquisition receivables for which an allowance was previously recorded. Offsetting these reductions was the impact of nine full months of expenses compared to two months of expenses in the nine months ended September 30, 2009.

Corporate Items selling, general and administrative expenses increased 25.7%, or $12.1 million, for the nine months ended September 30, 2010, as compared to the same period in 2009 primarily due to increases in salaries and bonuses ($8.8 million), stock-based compensation costs primarily related to the recording of the 2009 and 2010 performance awards expense ($4.9 million), increased employer contribution costs related to U.S. and Canadian retirement savings plans ($2.8 million), marketing and branding costs ($1.8 million), rent, taxes and other costs ($0.6 million), year-over-year severance costs ($0.6 million), computer expenses ($0.5 million) and recruiting costs ($0.5 million), offset by a reduction in professional fees primarily related to incurring acquisition costs in 2009 associated with the Eveready acquisition ($5.7 million), and year-over-year favorable changes in environmental liability estimates ($2.7 million).

Depreciation and Amortization

Landfill and other amortization	13,754		9,621
Total depreciation and amortization	$	67,671	$	42,951

Depreciation and amortization increased 57.6%, or $24.7 million, in the first nine months of 2010 compared to the same period in 2009. Depreciation of fixed assets increased primarily due to the acquisitions of Eveready in July 2009 and Sturgeon in April 2010 and other increased capital expenditures in recent periods. Landfill and other amortization increased primarily due to the increase in other intangible assets resulting from the acquisition of Eveready and an increase in landfill volumes.

Other (Loss) Income

Other (loss) income increased $2.3 million in the nine months ended September 30, 2010 compared to the same period in 2009, primarily due to a $2.4 million gain on sale of certain marketable securities.

Interest Expense, Net

Interest expense	$	22,336		$	10,433
Interest income	(564		)	(888		)
Interest expense, net	$	21,772		$	9,545

Interest expense, net increased $12.2 million in the first nine months of 2010 compared to the same period in 2009. The increase in interest expense was primarily due to the issuance of $300.0 million in senior secured notes in August 2009, borrowed to finance the acquisition of Eveready, and the refinancing of our revolving credit facility. The reduction of interest income in the same period was primarily due to a reduction in the interest rates being earned on our cash balances.

Loss on Early Extinguishment of Debt

During the third quarter of 2010, we recorded a $2.3 million loss on the early extinguishment of debt for the redemption of $30.0 million of our then outstanding $300.0 million senior secured notes. The loss included a $0.9 million premium and non-cash expenses of $0.7 million related to unamortized financing costs and $0.7 million of unamortized discount.

During the third quarter of 2009, we recorded a $4.9 million loss on the early extinguishment of debt for the repayment of the Company’s $30.0 million term loan which was due in 2010, the Company’s $23.7 million outstanding senior secured notes, and the Eveready credit facility assumed in connection with that acquisition. The loss included $0.7 million and $2.2 million in prepayment

penalties on the senior secured notes and Eveready credit facility, respectively, other fees of $0.2 million and non-cash expenses of $1.7 million and $0.1 million for unamortized financing costs and discount, respectively.

Income from Discontinued Operations

In connection with our acquisition of Eveready, we agreed with the Canadian Commissioner of Competition to divest Eveready’s Pembina Area Landfill, located near Drayton Valley, Alberta, due to its proximity to our existing landfill in the region. Prior to its sale in April 2010, the Pembina Area Landfill met the held for sale criteria and therefore the fair value of its assets and liabilities less estimated costs to sell were recorded as held for sale in our consolidated balance sheet. In connection with this sale, we recognized a pre-tax gain of $1.3 million which, along with the net income through April 30, 2010 for the Pembina Area Landfill, has been recorded in income from discontinued operations on our consolidated statement of income for the nine months ended September 30, 2010. From January 1, 2010 to April 30, 2010, the Pembina Area Landfill recorded $2.2 million of revenues which are included in income from discontinued operations.

In addition to the above, we sold the mobile industrial health business in the second quarter of 2010 and recognized a $1.4 million pre-tax gain on sale which was recorded in income from discontinued operations.

Income Taxes

The Company’s effective tax rate (including taxes on income from discontinued operations) for the three and nine months ended September 30, 2010 was 38.6% and 29.1%, compared to 43.6% and 43.8% for the same periods in 2009. The decrease in the effective tax rate for the nine months ended September 30, 2010 was primarily attributable to the decrease in unrecognized tax benefits recorded as a discrete item in the second quarter of 2010. The higher effective tax rate for the three months ended September 30, 2009 as compared to the same period in 2010 was primarily due to the non-deductible acquisition costs related to the acquisition of Eveready recorded in 2009. In addition, the overall decrease in the effective rate for 2010 as compared to 2009 was the result of increased earnings in Canada which has a lower statutory tax rate as compared to the United States.

Income tax expense (including taxes on income from discontinued operations) for the three months ended September 30, 2010 increased $17.3 million to $24.4 million from $7.1 million for the comparable period in 2009. Income tax expense (including taxes on income from discontinued operations) for the nine months ended September 30, 2010 increased $26.3 million to $44.0 million from $17.7 million for the comparable period in 2009. The increased tax expense for the three months ended September 30, 2010 was primarily due to increased revenue and earnings. The increased tax expense for the nine months ended September 30, 2010 was primarily due to increased revenue and earnings offset by a decrease in unrecognized tax benefits of $14.0 million. Approximately $13.1 million of the $14.0 million decrease was due to expiring statute of limitation periods related to a historical Canadian business combination and the remaining $0.9 million was related to the conclusion of examinations with state taxing authorities and the expiration of various state statutes of limitation periods.

A valuation allowance is required to be established when, based on an evaluation of available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. At September 30, 2010 and December 31, 2009, we had a remaining valuation allowance of $10.1 million and $11.2 million, respectively. The allowance as of September 30, 2010 consisted of $9.2 million of foreign tax credits, $0.9 million of state net operating loss carryforwards and less than $0.1 million of foreign net operating loss carryforwards. The allowance as of December 31, 2009 consisted of $9.2 million of foreign tax credits, $0.9 million of state net operating loss carryforwards and $1.1 million of foreign net operating loss carryforwards. The reduction in the valuation allowance was due to the release of foreign net operating loss carryforwards for a dissolved entity.

Management’s policy is to recognize interest and penalties related to income tax matters as a component of income tax expense. The liability for unrecognized tax benefits as of September 30, 2010 and December 31, 2009, included accrued interest and penalties of $25.5 million and $28.0 million, respectively. Tax expense for the three months ended September 30, 2010 and 2009 included interest and penalties of $0.6 million and $1.1 million, respectively. Tax expense for the nine months ended September 30, 2010 and 2009 included interest and penalties of $2.3 million and $2.6 million, respectively.

Liquidity and Capital Resources

Cash and Cash Equivalents

During the nine months ended September 30, 2010, cash and cash equivalents increased $47.4 million primarily due to the following:

Table of Contents

· Collections received from the two oil spill projects in the Gulf and Michigan of $181.0 million offset by vendor payments of approximately $106.9 million;

· Divestitures in April 2010 of the Pembina Area Landfill for $11.7 million and the mobile industrial health business for $2.4 million (discussed further in Note 10, “Held For Sale,” to our financial statements included in Item 1 of this report);

· Sale of certain marketable securities for $2.6 million; offset partially by:

· Redemption on September 28, 2010 of $30.0 million of our then outstanding $300.0 million senior secured notes;

· Purchase of Sturgeon & Son Transportation, Inc. in April 2010 for cash of $13.4 million (discussed further in Note 3, “Business Combinations,” to our financial statements included in Item 1 of this report);

· Timing of interest payments on our senior secured notes; and

· Payment in March 2010 of bonuses and commissions earned throughout 2009.

We intend to use our existing cash and cash equivalents, marketable securities and cash flow from operations to provide for our working capital needs, for potential acquisitions, and to fund capital expenditures. The Company expects to spend approximately $100 million for the year ending December 31, 2010 in capital expenditures. We anticipate that our cash flow provided by operating activities will provide the necessary funds on a short- and long-term basis to meet operating cash requirements.

We had accrued environmental liabilities as of September 30, 2010 of approximately $176.2 million, substantially all of which we assumed in connection with our acquisition of the CSD assets in September 2002, Teris LLC in 2006, and one of the two solvent recycling facilities we purchased from Safety-Kleen Systems, Inc. in 2008. We anticipate our environmental liabilities will be payable over many years and that cash flow from operations will generally be sufficient to fund the payment of such liabilities when required. However, events not anticipated (such as future changes in environmental laws and regulations) could require that such payments be made earlier or in greater amounts than currently anticipated, which could adversely affect our results of operations, cash flow and financial condition.

We assess our liquidity in terms of our ability to generate cash to fund our operating, investing and financing activities. Our primary ongoing cash requirements will be to fund operations, capital expenditures, interest payments and investments in line with our business strategy. We believe our future operating cash flows will be sufficient to meet our future operating and investing cash needs. Furthermore, the existing cash balances and the availability of additional borrowings under our revolving credit facility provide additional potential sources of liquidity should they be required.

Cash Flows for the nine months ended September 30, 2010

Cash from operating activities in the first nine months of 2010 was $153.9 million, an increase of 131.4%, or $87.4 million, compared with cash from operating activities in the first nine months of 2009. The change was primarily related to the activity from the two oil spill projects in the Gulf of Mexico and Michigan which resulted in an increase in income from operations and an increase in accounts payable offset by a net increase in accounts receivable.

Cash used for investing activities in the first nine months of 2010 was $72.1 million, a decrease of 28.8%, or $29.1 million, compared with cash used for investing activities in the first nine months of 2009. The decrease resulted primarily from lower year-over-year costs associated with acquisitions as well as proceeds related to the divestitures of the Pembina Area Landfill and the mobile industrial health business, offset by increased additions to property, plant and equipment

Cash used for financing activities in the first nine months of 2010 was $34.9 million compared with cash from financing activities of $2.2 million in the first nine months of 2009. The change was primarily the result of (i) net proceeds of $292.1 million from the August 2009 issuance of senior secured notes, offset by the payment on debt acquired related to the 2009 acquisitions of EnviroSORT Inc. and Eveready and (ii) the difference between the redemption of debt amounts between years.

Cash Flows for the nine months ended September 30, 2009

Cash from operating activities in the first nine months of 2009 was $66.5 million, a decrease of 9.4%, or $6.9 million, compared with cash from operating activities in the first nine months of 2008. The decrease was primarily the result of a reduction in income from operations.

Cash used for investing activities in the first nine months of 2009 was $101.2 million, an increase of 51.7%, or $34.5 million, compared with cash used for investing activities in the first nine months of 2008. The increase resulted primarily from higher year-over-year costs associated with acquisitions.

Cash used for financing activities in the first nine months of 2009 was $2.2 million, compared to cash from financing activities of $130.3 million in the first nine months of 2008. The change was primarily the result of net proceeds of $173.6 million from the

issuance of 2.875 million shares of common stock in April 2008 and the net proceeds of $292.1 million from the August 2009 issuance of senior secured notes offset by the payment on debt acquired related to the 2009 acquisitions of EnviroSORT and Eveready.

Financing Arrangements

On September 28, 2010, we redeemed $30.0 million (10% of the total of $300.0 million then outstanding) of our 7.625% senior secured notes in accordance with the terms of the notes. The notes permit management, at any time prior to August 15, 2012, but not more than once in any twelve-month period, to make an optional redemption of up to $30.0 million at a redemption price of 103% of the principal amount, plus accrued interest through the redemption date. The financing arrangements and principal terms of the original $300 million principal amount of senior secured notes and the $120 million revolving credit facility are discussed further in Note 10, “Financing Arrangements,” in our Annual Report on Form 10-K for the year ended December 31, 2009.

Effective October 1, 2010, the interest rate for borrowings under the revolving credit facility was reduced to either, at our option, (i) LIBOR plus an applicable margin ranging from 2.25% to 2.75% (as compared to 3.25% to 3.75% previously in effect) per annum based on the then level of our fixed charge coverage ratio or (ii) Bank of America, N.A.’s base rate plus an applicable margin ranging from 1.25% to 1.75% (as compared to 2.25% to 2.75% previously in effect) per annum based on such fixed charge coverage ratio, and the fee for outstanding letters of credit was reduced to the applicable reduced LIBOR margin described above.

As of September 30, 2010, we were in compliance with the covenants of our debt agreements.

Liquidity Impacts of Uncertain Tax Positions

As discussed in Note 11, “Income Taxes,” to our financial statements included in Item 1 of this report, we have recorded $65.6 million of unrecognized tax benefits, including $19.0 million of potential interest and $6.5 million of potential penalties. These liabilities are classified as “unrecognized tax benefits and other long-term liabilities” in our consolidated balance sheets. We are not able to reasonably estimate when we would make any cash payments to settle these liabilities. However, we believe no material cash payments will be required in the next 12 months.

Auction Rate Securities

As of September 30, 2010, our long-term investments included $5.4 million of available for sale auction rate securities. With the liquidity issues experienced in global credit and capital markets, these auction rate securities have experienced multiple failed auctions and as a result are currently not liquid. The auction rate securities are secured by student loans substantially insured by the Federal Family Education Loan Program, maintain the highest credit rating of AAA, and continue to pay interest according to their stated terms with interest rates resetting generally every 28 days.

We believe we have sufficient liquidity to fund operations and do not plan to sell our auction rate securities in the foreseeable future at an amount below the original purchase value. During the three-month period ended June 30, 2010, we liquidated $1.3 million of auction rate securities at par. In the unlikely event that we need to access the funds that are in an illiquid state, we may not be able to do so without a possible loss of principal until a future auction for these investments is successful, another secondary market evolves for these securities, they are redeemed by the issuer, or they mature. If we were unable to sell these securities in the market or they are not redeemed, we could be required to hold them to maturity. These securities are currently reflected at their fair value utilizing a discounted cash flow analysis or significant other observable inputs. As of September 30, 2010, we have recorded an unrealized pre-tax loss of $0.3 million, which we assess as temporary. We will continue to monitor and evaluate these investments on an ongoing basis for other than temporary impairment and record a charge to earnings if and when appropriate.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

In the normal course of business, we are exposed to market risks, including changes in interest rates, certain commodity prices, and certain foreign currency rates, primarily the Canadian dollar. Our philosophy in managing interest rate risk is to borrow at fixed rates for longer time horizons to finance non-current assets and to borrow (to the extent, if any, required) at variable rates for working capital and other short-term needs. We therefore have not entered into derivative or hedging transactions, nor have we entered into transactions to finance off-balance sheet debt. The following table provides information regarding our fixed rate borrowings at September 30, 2010 (in thousands):

Table of Contents

Scheduled Maturity Dates	Three Months Remaining 2010			2011			2012			2013			2014			Thereafter			Total
Senior secured notes	$	—		$	—		$	—		$	—		$	—		$	263,799		$	263,799
Capital lease obligations	3,277			5,995			3,366			1,844			1,444			172			16,098
	$	3,277		$	5,995		$	3,366		$	1,844		$	1,444		$	263,971		$	279,897
Weighted average interest rate on fixed rate borrowings	7.6		%	7.6		%	7.6		%	7.6		%	7.6		%	7.6		%

In addition to the fixed rate borrowings described in the above table, we had at September 30, 2010 variable rate instruments that included a revolving credit facility with maximum borrowings of up to $120.0 million (with a $110.0 million sub-limit for letters of credit).

We view our investment in our foreign subsidiaries as long-term; thus, we have not entered into any hedging transactions between any two foreign currencies or between any of the foreign currencies and the U.S. dollar. During 2010, the Canadian subsidiaries transacted approximately 3.6% of their business in U.S. dollars and at any period end have cash on deposit in U.S. dollars and outstanding U.S. dollar accounts receivable related to these transactions. These cash and receivable accounts are vulnerable to foreign currency translation gains or losses. Exchange rate movements also affect the translation of Canadian generated profits and losses into U.S. dollars. Had the Canadian dollar been 10.0% stronger or weaker against the U.S. dollar, we would have reported increased or decreased net income of $0.8 million and $0.3 million for the three months ended September 30, 2010 and 2009, respectively. Had the Canadian dollar been 10.0% stronger or weaker against the U.S. dollar, we would have reported increased or decreased net income of $3.3 million and $0.1 million for the nine months ended September 30, 2010 and 2009, respectively.

At September 30, 2010, $5.4 million of our noncurrent investments were auction rate securities. While we are uncertain as to when the liquidity issues relating to these investments will improve, we believe these issues will not materially impact our ability to fund our working capital needs, capital expenditures, or other business requirements.

We are subject to minimal market risk arising from purchases of commodities since no significant amount of commodities are used in the treatment of hazardous waste or providing energy and industrial services.
