CLEAN HARBORS, INC. AND SUBSIDIARIES

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

(1) BASIS OF PRESENTATION

The accompanying consolidated interim financial statements are unaudited and 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 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 or any other interim periods. 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, 2012.
    
During the first quarter of 2013, the Company adjusted its operating segments to integrate the business activities of Safety-Kleen, Inc. and its subsidiaries (collectively, “Safety-Kleen”) acquired in December 2012, and to incorporate other changes made in 2013 to the manner in which the Company manages its business, makes operating decisions and assesses its performance. Under the new structure, the Company's operations are managed in five reportable segments: Technical Services, Oil Re-refining and Recycling, SK Environmental Services, Industrial and Field Services and Oil and Gas Field Services. The prior year segment information has been recast to conform to the current year presentation. See Note 17, “Segment Reporting.”
(2) SIGNIFICANT ACCOUNTING POLICIES
The Company's significant accounting policies are described in Note 2, "Significant Accounting Policies," in the Company's Annual Report on Form 10-K for the year ended December 31, 2012. On December 28, 2012, the Company acquired 100% of the outstanding common shares of Safety-Kleen. See Note 3, “Business Combinations.” No revenue, expense, income or loss of Safety-Kleen was included in the Company's consolidated statements of income for the year ended December 31, 2012 due to the immateriality of the operating results subsequent to December 28, 2012.
Safety-Kleen's operating results are included in the Company's unaudited consolidated statements of income for the three and six months ended June 30, 2013, and reflect the application of certain significant accounting policies as described below:
Revenue Recognition and Deferred Revenue
S-K Environmental Services revenue is generated from providing parts cleaning services, containerized waste services, oil collection services and other complementary products and services.
Parts cleaning services generally consist of placing a specially designed parts washer at a customer's premises and then, on a recurring basis, delivering clean solvent or aqueous-based washing fluid, cleaning and servicing the parts washer and removing the used solvent or aqueous fluid. The Company also services customer-owned parts washers. Revenue from parts cleaning services is recognized over the service interval. Service intervals represent the actual amount of time between service visits to a particular parts cleaning customer. Average service intervals vary from seven to fourteen weeks depending on several factors, such as customer accommodation, types of machines serviced and frequency of use.
Containerized waste services consist of profiling, collecting, transporting and recycling or disposing of a wide variety of hazardous and non-hazardous wastes. Revenue is recognized upon disposal. The Company tracks the amount of time it takes from collection of the customer's waste to delivery to the disposal outlet, which represents a deferral period of approximately two and one-half weeks.
Oil collection services consist of collecting used oil which is transferred to the Oil Re-refining and Recycling segment. Revenue is recognized when services are performed.
Other complementary products and services include vacuum services, allied products and other environmental services. Revenue is recognized when products are delivered and services are performed.
Oil Re-refining and Recycling revenue is generated from re-refining used oil to produce high quality base and blended lubricating oils, and recycling used oil collected in excess of the Company's re-refining capacity into recycled fuel oil. The high quality base and blended lubricating oils are sold to third-party distributors, retailers, government agencies, fleets, railroads and industrial customers. The recycled fuel oil is sold to asphalt plants, industrial plants, blenders, pulp and paper companies, vacuum gas

oil producers and marine diesel oil producers. Revenue is recognized upon delivery.
Deferred Costs Relating to Deferred Revenue
Commissions and other incremental direct costs, primarily costs of materials and transportation expenses, relating to deferred revenue from the Company’s parts cleaning services, containerized waste services and vacuum services are capitalized and deferred. The deferred costs are included in current assets in the consolidated balance sheet and expensed when the related revenues are recognized.
Recent Accounting Pronouncements
In July 2013, the Financial Accounting Standards Board (“FASB”) issued ASU 2013-11 Income Taxes (Topic 740) - Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. This standard provides guidance regarding when an unrecognized tax benefit should be classified as a reduction to a deferred tax asset or when it should be classified as a liability in the consolidated balance sheet. The guidance is effective for the Company on January 1, 2014. Management does not expect the adoption of this standard to have a significant impact on the Company's consolidated balance sheet.
In February 2013, the FASB issued ASU 2013-02 Comprehensive Income (Topic 220) - Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. The new guidance requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income (“AOCI”) by component. Entities are required to present, either on the face of the income statement where net income is presented or in the notes, significant amounts reclassified out of AOCI by respective line items of net income if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required to be reclassified in their entirety to net income, entities are required to cross-reference the disclosures required under U.S. GAAP that provide additional detail about those amounts. This guidance is effective prospectively for annual and interim reporting periods beginning after December 31, 2012. The Company adopted the standard on January 1, 2013. The amounts required to be disclosed under this guidance are disclosed in Note 14, “Accumulated Other Comprehensive (Loss) Income.”
Reclassifications
The Company's revenues and cost of revenues in the consolidated statements of income for the three and six months ended June 30, 2012 and the changes in assets and liabilities, net of acquisitions in the consolidated statements of cash flows for the six months ended June 30, 2012 have been reclassified to conform to the current year presentation.
(3) BUSINESS COMBINATIONS
Safety-Kleen, Inc.
On December 28, 2012, the Company acquired 100% of the outstanding common shares of Safety-Kleen for approximately $1.3 billion. The purchase price consisted of an all-cash purchase price of $1.25 billion, plus a $7.3 million adjustment for the amount by which the estimated net working capital (excluding cash) of Safety-Kleen on the closing date exceeded $50.0 million. The purchase price is subject to adjustment upon finalization of Safety-Kleen's net working capital balance (excluding cash) as of the closing date. The Company incurred acquisition-related costs of approximately $0.1 million and $1.3 million in connection with the transaction which are included in selling, general and administrative expenses in the consolidated statements of income for the three and six months ended June 30, 2013, respectively. The Company financed the purchase through a combination of approximately $300.0 million of existing cash, $369.3 million in net proceeds from the Company's public offering of 6.9 million shares of Clean Harbors common stock, and approximately $589.0 million in net proceeds from the Company's private debt offering of $600.0 million of 5.125% senior unsecured notes due 2021. Safety-Kleen, headquartered in Richardson, Texas, is the largest re-refiner and recycler of used oil in North America and a leading provider of parts cleaning and environmental services to commercial, industrial and automotive customers. In conjunction with the transaction, Safety-Kleen, Inc. and its subsidiaries became wholly-owned subsidiaries of Clean Harbors.
The fair value of all the acquired identifiable assets and liabilities summarized below is provisional pending finalization of the Company's acquisition accounting. Measurement period adjustments reflect new information obtained about facts and circumstances that existed as of the acquisition date. The Company believes that such preliminary allocations provide a reasonable basis for estimating the fair values of assets acquired and liabilities assumed but the Company is waiting for additional information necessary to finalize fair value. The Company expects to finalize the valuation and complete the purchase price allocation as soon as practicable but no later than one year from the acquisition date. Final determination of the fair value may result in further adjustments

The fair value of the assets acquired includes customer receivables with a preliminary aggregate fair value of $133.9 million. Combined gross amounts due were $143.9 million.
(ii)
Goodwill represents the excess of the fair value of the net assets acquired over the purchase price. Goodwill of $210.1 million, $144.6 million, $68.7 million, and $2.1 million has been recorded on a preliminary basis in the Oil Re-refining and Recycling, SK Environmental Services, Industrial and Field Services and Technical Services segments, respectively. None of the goodwill related to this acquisition will be deductible for tax purposes.
The Company has determined that the separate disclosure of Safety-Kleen's revenues and earnings is impracticable for the three and six months ended June 30, 2013 due to the integration of Safety-Kleen operations into the Company upon acquisition.
The following unaudited pro forma combined summary financial information presented below gives effect to the following transactions as if they had occurred as of January 1, 2011, and assumes that there were no material, non-recurring pro forma adjustments directly attributable to: (i) the acquisition of Safety-Kleen, (ii) the sale of 6.9 million shares of the Company's common stock, (iii) the issuance of $600.0 million aggregate principal amount of 5.125% senior unsecured notes due 2021, and (iv) the payment of related fees and expenses (in thousands).

providing catalyst loading and unloading services in the United States and Canada. The combined purchase price for these acquisitions was approximately $108.1 million, including the assumption and payment of debt of $7.7 million and post-closing adjustments of $1.3 million based upon the assumed target amounts of working capital. Management has determined the preliminary purchase price allocations based on estimates of the fair values of all tangible and intangible assets acquired and liabilities assumed. Such amounts are subject to adjustment based on the additional information necessary to determine fair values. The Company believes that such information provides a reasonable basis for estimating the fair values of assets acquired and liabilities assumed, but the Company is waiting for additional information necessary to finalize fair value.
As of June 30, 2013, the Company had finalized the acquisition accounting of the identified acquired assets and liabilities for the acquisitions completed in the third quarter of 2012 and the second quarter of 2012. The Company has not finalized the acquisition accounting for the acquisition completed in the fourth quarter of 2012. The Company expects to finalize the remaining valuation and complete the purchase price allocation as soon as practicable but no later than one year from the acquisition dates. Final determination of the fair value may result in further adjustments to the values presented below (in thousands).

(4) FAIR VALUE MEASUREMENTS
The Company’s financial instruments consist of cash and cash equivalents, marketable securities, receivables, trade payables, auction rate securities, derivative financial instruments and long-term debt. The estimated fair value of cash equivalents, receivables, and trade payables approximate their carrying value due to the short maturity of these instruments and are deemed to be Level 2 in the fair value hierarchy. The fair value of the Company’s unsecured senior notes (due 2020 and 2021) at June 30, 2013

________________________________________________
(i)
The auction rate securities are classified as available-for-sale and the fair value of these securities was estimated utilizing a probability discounted cash flow analysis. As of June 30, 2013, all of the Company's auction rate securities continue to have AAA underlying ratings. The Company attributes the $0.3 million decline in the fair value of the 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 it does not intend to sell and it is more likely than not that the Company will not have to sell the securities before their maturity. During the six months ended June 30, 2013 and 2012, the Company recorded an unrealized pre-tax loss of less than $0.1 million and a pre-tax gain of $0.1 million, respectively, on its auction rate securities. 
(ii)
The fair value of derivatives is recorded based on the present value of cash flows using a crude oil forward rate curve.
(iii)
The fair value of marketable securities is recorded based on quoted market prices and changes in fair value were included in other comprehensive income.

Derivative Financial Instruments
The Company acquired several commodity derivatives with the Safety-Kleen acquisition on December 28, 2012. The Company uses commodity derivatives to manage against significant fluctuations in oil and oil derivative commodity prices and indices, specifically the ICIS-LOR rate and 6-oil index. All commodity derivatives are comprised of cashless collar contracts related to crude oil prices, pursuant to which the Company sells a call to a bank and then purchases a put from the same bank. The derivative instruments are not designated as hedges and expire in 2013 and 2014.

The goodwill related to the 2012 acquisitions includes estimates that are subject to change based upon final fair value determinations.     
The Company assesses goodwill for impairment at least on an annual basis as of December 31, or when events or changes in the business environment indicate that the carrying value of the reporting unit may exceed its fair value, by comparing the fair value of each reporting unit to its carrying value, including goodwill. As previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2012, the Company continues to assess the performance of its Oil and Gas Field Services reporting unit. The lower than anticipated results in the second quarter of 2013 were primarily due to historic flooding conditions in Western Canada. The Company performed an interim sensitivity analysis of the impact of the lower than anticipated results on the reporting unit's fair value in the second quarter, and concluded the fair value of the reporting unit more likely than not exceeds its carrying value at June 30, 2013. The financial performance of this reporting unit is affected by weather conditions and fluctuations in oil and

gas prices. The Company has been closely monitoring its performance, and will continue to assess this reporting unit's performance. There can be no assurance that future events will not result in an impairment of goodwill.

On January 17, 2013, the Company increased its revolving credit facility to provide for maximum borrowings of up to $400.0 million (with a $325.0 million sub-limit for letters of credit). At June 30, 2013, the revolving credit facility had no outstanding loans, $262.5 million available to borrow and $137.5 million of letters of credit outstanding.
The financing arrangements and principal terms of the Company's $800.0 million principal amount of 5.25% senior unsecured notes due 2020 ("2020 Notes") and $600.0 million principal amount of 5.125% senior unsecured notes due 2021 ("2021 Notes") which were outstanding at June 30, 2013, and the Company's amended $400.0 million revolving credit facility, are discussed further in Note 11, “Financing Arrangements,” in the Company's Annual Report on Form 10-K for the year ended December 31, 2012.
(12) INCOME TAXES 
The Company’s effective tax rate for the three and six months ended June 30, 2013 was 35.1% and 34.2%, respectively, compared to 35.8% and 36.0% for the same periods in 2012.
As of June 30, 2013, the Company had recorded $3.9 million of liabilities for unrecognized tax benefits and $1.5 million of interest. As of December 31, 2012, the Company had recorded $3.5 million of liabilities for unrecognized tax benefits and $1.4 million of interest. 
Due to expiring statute of limitation periods, the Company believes that total unrecognized tax benefits will decrease by approximately $3.7 million within the next twelve months. The $3.7 million (which includes interest of $1.2 million) is related to various foreign and state tax laws and, if realized, will be recorded in earnings and therefore will impact the effective income tax rate.

(16) 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 June 30, 2013 and December 31, 2012, the Company had recorded reserves of $42.2 million and $38.6 million, respectively, in the Company's financial statements for actual or probable liabilities related to the legal and administrative proceedings in which the Company was then involved, the principal of which are described below. At June 30, 2013 and December 31, 2012, the Company also believed that it was reasonably possible that the amount of these potential liabilities could be as much as $3.5 million more, respectively. The Company periodically adjusts the aggregate amount of these reserves when these actual or probable liabilities are paid or otherwise discharged, new claims arise, or additional relevant information about existing or probable claims becomes available. As of June 30, 2013, the $42.2 million of reserves consisted of (i) $34.4 million related to pending legal or administrative proceedings, including Superfund liabilities, which were included in remedial liabilities on the consolidated balance sheets and (ii) $7.8 million primarily related to federal and state enforcement actions, which were included in accrued expenses on the consolidated balance sheets.
As of June 30, 2013, the principal legal and administrative proceedings in which the Company was involved, or which had been terminated during 2013, 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

17

Table of Contents

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 Canadian dollar ("CDN") total of $1.6 million 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 June 30, 2013 and December 31, 2012, the Company had accrued $13.4 million and $14.2 million, respectively, for remedial liabilities relating to the Ville Mercier legal proceedings.
Safety-Kleen Legal Proceedings. On December 28, 2012, the Company acquired Safety-Kleen and thereby became subject to the legal proceedings in which Safety-Kleen was a party on that date. In addition to certain Superfund proceedings in which Safety-Keen has been named as a potentially responsible party as described below under “Superfund Proceedings,” the principal such legal proceedings involving Safety-Kleen which were outstanding as of June 30, 2013 are as follows:
Product Liability Cases - Safety-Kleen is named as a defendant in various lawsuits that are currently pending in various courts and jurisdictions throughout the United States, including approximately 64 proceedings (excluding cases which have been settled but not formally dismissed) as of June 30, 2013, wherein persons claim personal injury resulting from the use of Safety-Kleen's parts cleaning equipment or cleaning products. These proceedings typically involve allegations that the solvent used in Safety-Kleen's parts cleaning equipment contains contaminants and/or that Safety-Kleen's recycling process does not effectively remove the contaminants that become entrained in the solvent during their use. In addition, certain claimants assert that Safety-Kleen failed to warn adequately the product user of potential risks, including a historic failure to warn that solvent contains trace amounts of toxic or hazardous substances such as benzene. Safety-Kleen maintains insurance that it believes will provide coverage for these claims (over amounts accrued for self-insured retentions and deductibles in certain limited cases), except for punitive damages to the extent not insurable under state law or excluded from insurance coverage. Safety-Kleen believes that these claims lack merit and has historically vigorously defended, and intends to continue to vigorously defend, itself and the safety of its products against all of these claims. Such matters are subject to many uncertainties and outcomes are not predictable with assurance. Consequently, Safety-Kleen is unable to ascertain the ultimate aggregate amount of monetary liability or financial impact with respect to these matters as of June 30, 2013. From December 31, 2012 to June 30, 2013, 19 product liability claims were settled or dismissed. Due to the nature of these claims and the related insurance, Safety-Kleen did not incur any expense as Safety-Kleen's insurance provided coverage in full for all such claims. Safety-Kleen may be named in similar, additional lawsuits in the future, including claims for which insurance coverage may not be available.    
Fee Class Action Claims. In October 2010, two customers filed a complaint, individually and on behalf of all similarly situated customers in the State of Alabama, in state court in Alabama alleging that Safety-Kleen improperly assessed fuel surcharges and extended area service fees. Safety-Kleen disputes the basis of the claims on numerous grounds, including that Safety-Kleen has contracts with numerous customers authorizing the assessment of such fees and that in cases where no contract exists Safety-Kleen provides customers with a document at the time of service reflecting the assessment of the fee, followed by an invoice itemizing the fee. It is Safety-Kleen's position that it had the right to assess fuel surcharges, that the customers consented to the charges and that the surcharges were voluntarily paid by the customers when presented with an invoice. The lawsuit is still in its initial stages of discovery, with the focus being whether a class will be certified. The class certification-related fact discovery cutoff is September 4, 2013, and a hearing on class certification will be held in early to mid-2014. In late June 2012, a nearly identical lawsuit was filed by the same law firm on behalf of a California-based customer. The lawsuit contends, under various state law theories, that Safety-Kleen impermissibly assessed fuel surcharges and late payment fees, and seeks certification of a class of California customers only. Safety-Kleen will assert the same defenses as in the Alabama litigation. In December 2012, a similar suit was filed by the same law firm on behalf of a Missouri-based customer which contends under various state law theories that Safety-Kleen impermissibly assessed fuel surcharges and seeks certification of a class of Missouri customers only. Safety-Kleen will assert the same defenses as in the Alabama and California cases. The Company is unable to

18

Table of Contents

ascertain the ultimate aggregate amount of monetary liability or financial impact with respect to these matters as of June 30, 2013, and no reserve has been recorded.
Superfund Proceedings
The Company has been notified that either the Company (which, since December 28, 2012, includes Safety-Kleen) 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 121 sites which are subject to or are proposed to become subject to proceedings under federal or state Superfund laws. Of the 121 sites, two involve facilities that are now owned by the Company and 119 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 119 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, six are currently requiring expenditures on remediation, 13 are now settled, and 16 are not currently requiring expenditures on remediation. The status of the two facilities owned by the Company (the Wichita Property and the BR Facility) are further described below.
The 119 Superfund sites described above include 69 sites for which the Company had been notified it is a PRP or potential PRP prior to the Company's acquisition of Safety-Kleen on December 28, 2012, and an additional 50 sites at which Safety-Kleen had been notified it is a PRP or potential PRP prior to such acquisition. The total number of Superfund sites at which the Company had at June 30, 2013 potential liability and the total dollar amount of such estimated liability relating to those sites as described above have been increased to reflect the additional potential Superfund liabilities to which the Company became subject as a result of the Safety-Kleen acquisition. One of the third party sites (the Marine Shale site) is further described below.
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 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 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.
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

19

Table of Contents

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.
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 Clean Harbors was never a customer of Marine Shale. A Safety-Kleen subsidiary was, however, a Marine Shale customer and has been named a PRP. 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. The Company has joined with other parties 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 June 30, 2013 and December 31, 2012, the amount of the Company's reserves relating to the Marine Shale site were $4.6 million and $4.4 million, respectively.
Certain Other Third Party Sites.    At 11 of the 119 third party sites, Clean Harbors has an indemnification agreement with ChemWaste, a former subsidiary of Waste Management, Inc., and at five additional of those third party sites, Safety-Kleen has a similar indemnification agreement with McKesson Corporation. These agreements indemnify the Company (which now includes Safety-Kleen) with respect to any liability at the 16 sites for waste disposed prior to the Company's (or Safety-Kleen's) acquisition of the former subsidiaries of Waste Management or McKesson which had shipped wastes to those sites. Accordingly, Waste Management or McKesson are paying all costs of defending those subsidiaries in those 16 cases, including legal fees and settlement costs. However, there can be no guarantee that the Company's ultimate liabilities for those 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. Except for the indemnification agreement which the Company holds from ChemWaste and McKesson, the Company does not have an indemnity agreement with respect to any of the 119 third party sites discussed above. In addition to Wichita, the BR Facility, and Marine Shale, Clean Harbors has 12 sites at which it believes its potential liability could exceed $100,000.

From time to time, the Company pays fines or penalties in regulatory proceedings relating primarily to waste treatment, storage or disposal facilities. As of June 30, 2013 and December 31, 2012, there were five proceedings for which the Company reasonably believed that the sanctions could equal or exceed $100,000. The Company believes that the fines or other penalties in these or any of the other regulatory proceedings will, individually or in the aggregate, not have a material effect on its financial condition, results of operations or cash flows.
(17) SEGMENT REPORTING 
During the first quarter of 2013, the Company adjusted its operating segments to integrate the business activities of Safety-Kleen, acquired in December 2012, and to incorporate other changes made in 2013 to the manner in which the Company manages its business, makes operating decisions and assesses its performance. The Company's operations are now managed in five reportable segments: Technical Services, Oil Re-refining and Recycling, SK Environmental Services, Industrial and Field Services and Oil and Gas Field Services. The prior year segment information has been recast to conform to the current year presentation.
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, provision for income taxes and pre-tax, non-cash acquisition accounting adjustments. Also excluded are loss on early extinguishment of debt, other income (expense) 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 Company’s estimate of fair value based on similar transactions with outside customers. 
The operations not managed through the Company’s five reportable 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 five 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 five reportable segments. Corporate Items revenues for the six months ended June 30, 2013 includes a one-time, non-cash reduction of approximately $10.2 million due to the impact of acquisition accounting adjustments on Safety-Kleen's historical deferred revenue balance at December 28, 2012. The revenue

Table of Contents

amounts of the five reportable segments for the six months ended June 30, 2013 exclude such adjustments to maintain comparability with future operating results and reflect how the Company manages the business.
The following table reconciles third party revenues to direct revenues for the three and six months ended June 30, 2013 and 2012 (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. Intersegment revenues represent the sharing of third party revenues among the segments based on products and services provided by each segment as if the products and services were sold directly to the third party. The intersegment revenues are shown net. The negative intersegment revenues are due to more transfers out of customer revenues to other segments than transfers in of customer revenues from other segments.

ITEM 2.                         MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS 
Forward-Looking Statements 
In addition to historical information, this Quarterly Report on 10-Q contains forward-looking statements, which are generally identifiable by use of the words “believes,” “expects,” “intends,” “anticipates,” “plans to,” “estimates,” “projects,” or similar expressions. These forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from those reflected in these forward-looking statements. Factors that might cause such a difference include, but are not limited to, those discussed under Item 1A, “Risk Factors,” in our Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 6, 2013, under Item 1A, “Risk Factors,” included in Part II—Other Information in this report, and in other documents we file from time to time with the Securities and Exchange Commission.  Readers are cautioned not to place undue reliance on these forward-looking statements, which reflect management’s opinions only as of the date hereof. We undertake no obligation to revise or publicly release the results of any revision to these forward-looking statements. 
General 
We are a leading provider of environmental, energy and industrial services throughout North America. 
Following our acquisition of Safety-Kleen in December 2012, we made changes in 2013 to the manner in which we manage our business, make operating decisions and assess our performance. The amounts presented for all periods herein have been recast to reflect the impact of such changes. Under the new structure, we report the business in five reportable segments, including: 
Technical Services — provides 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.
Oil Re-refining and Recycling — processes used oil into high quality base and blended lubricating oils, which are then sold to third party customers and provide recycling of oil in excess of Safety-Kleen's current re-refining capacity into recycled fuel oil which is then sold to third parties. Processing into base and blended lubricating oils takes place in the Company's two owned and operated re-refineries and recycling of oil into recycled fuel oil takes place in one of the Company's used oil terminals.
SK Environmental Services — provides a broad range of environmental services, such as parts cleaning, containerized waste services, oil collection, and other complementary products and services, including vacuum services, allied products and other environmental services.
Industrial and Field Services — provides industrial and specialty services, such as high-pressure and chemical cleaning, catalyst handling, decoking, material processing, and industrial lodging services to refineries, chemical plants, oil sands facilities, pulp and paper mills, and other industrial facilities. Also provides 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.
Oil & Gas Field Services — provides fluid handling, fluid hauling, production servicing, surface rentals, seismic services, and directional boring services to the energy sector serving oil and gas exploration, production, and power generation. 
Acquisition of Safety-Kleen
On December 28, 2012, we acquired 100% of the outstanding common shares of Safety-Kleen for approximately $1.3 billion. The purchase price consisted of an all-cash purchase price of $1.25 billion, plus a $7.3 million adjustment for the amount by which the estimated net working capital (excluding cash) of Safety-Kleen on the closing date exceeded $50.0 million. The purchase price is subject to adjustment upon finalization of Safety-Kleen's net working capital balance (excluding cash) as of the closing date. We financed the purchase through a combination of approximately $300.0 million of existing cash, $369.3 million in net proceeds from our public offering of 6.9 million shares of our common stock, and approximately $589.0 million in net proceeds from our private debt offering of $600.0 million of 5.125% senior unsecured notes due 2021.
Safety-Kleen, headquartered in Richardson, Texas, is the largest re-refiner and recycler of used oil in North America and a leading provider of parts cleaning and environmental services to commercial, industrial and automotive customers. In conjunction with the transaction, Safety-Kleen, Inc. and its subsidiaries became wholly-owned subsidiaries of Clean Harbors.

Summary of Operations
 During the three months ended June 30, 2013, our revenues were $860.5 million, compared with $523.1 million during the three months ended June 30, 2012. The 64% increase in revenue was primarily driven by our acquisition of Safety-Kleen in December 2012.
Our Technical Services revenues accounted for 33% of our total revenues for the three months ended June 30, 2013.  The year-over-year increase in revenues of 12% resulted partially from our acquisition of Safety-Kleen contributing to volume into our incineration facilities. The utilization rate at our incinerators was 92.3% for the three months ended June 30, 2013, compared with 90.3% in the comparable period of 2012 despite a three week unplanned shutdown at our Deer Park facility, and our landfill volumes increased by approximately 17% year-over-year as a result of large-scale project work.
Our Oil Re-refining and Recycling revenues accounted for 9% of our total revenues for the three months ended June 30, 2013. During the second quarter, the pricing environment in Group 2 base oil was stable as posted industry prices were unchanged from April 1 to June 30. Revenue were down from the first quarter as a result of lower volumes of blended lubricant sales.
Our SK Environmental Services revenues accounted for 23% of our total revenues for the three months ended June 30, 2013. Revenue increased from the first quarter and we continued to see steady volumes from our small quantity generator business, parts washers and waste oil collection during the second quarter. 
Our Industrial and Field Services revenues accounted for 27% of our total revenues for the three months ended June 30, 2013. The year-over-year increase in revenue of 22% was primarily due to growth in the Oil sands region of Canada, increases in our field services business, high occupancy in our fixed lodges and positive contributions from several acquisitions.  
Our Oil and Gas Field Services revenues accounted for 8% of our total revenues for the three months ended June 30, 2013. The year-over-year decrease of 10% was primarily due to the lower rig count in Western Canada. We also experienced an early and extended spring break-up period and historic flooding in Western Canada during the second quarter of 2013 which resulted in certain project delays.  
Our cost of revenues increased from $367.6 million during the three months ended June 30, 2012 to $614.3 million during the three months ended June 30, 2013.  Our cost of revenues increased primarily due to our acquisition of Safety-Kleen in December 2012.  Our gross profit margin was 28.6% for the three months ended June 30, 2013, compared to 29.7% in the same period last year. The year-over-year decrease in gross margin percentage was primarily due to the acquisition of Safety-Kleen, which carries a lower margin, and the decreased margin in our Oil and Gas Field Services as a result of lower revenue.
During the three months ended June 30, 2013, our effective tax rate was 35.1%, compared with 35.8% for the same period last year. The decrease in the effective tax rate for the three months ended June 30, 2013 was primarily attributable to lower accrued interest and penalties related to unrecognized tax benefits in 2013 as compared to the same period for 2012.
Environmental Liabilities 
The net reductions in our estimated environmental liabilities during the three months ended June 30, 2013 were due primarily to expenditures. The benefits over the past few years were primarily due to changes in environmental liability estimates as a result of the successful introduction of new technology for remedial activities, favorable results from environmental studies of the on-going remediation, including favorable regulatory approvals, and lower project costs realized by utilizing internal labor and equipment. During the three and six months ended June 30, 2013, there were no significant charges (benefits) resulting from changes in environmental liability estimates.
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, 2012, 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, provision for income taxes and pre-tax, non-cash acquisition accounting adjustments. Also excluded are loss on early extinguishment of debt, other income (expense) and income from discontinued operations, net of tax as these amounts are not considered part of usual business operations.  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.
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 summarize Adjusted EBITDA contribution by reportable segment for the three and six months ended June 30, 2013 and 2012 (in thousands). We consider the Adjusted EBITDA contribution from each 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 segment Adjusted EBITDA contribution. Prior year amounts presented have been recast to reflect the changes made to our segment presentation in the first quarter of 2013 as described in Note 17, "Segment Reporting." This table and subsequent discussions should be read in conjunction with Item 6, "Selected Financial Data" and Item 8, "Financial Statements and Supplementary Data" and in particular Note 18, "Segment Reporting," included in our Annual Report on Form 10-K for the year ended December 31, 2012 and Item 1, "Unaudited Financial Statements" and in particular Note 17, "Segment Reporting," in this report.

Revenues 
Technical Services revenues increased 12.4%, or $31.2 million, in the three months ended June 30, 2013 from the comparable period in 2012 primarily due to strong contributions from our projects business, growth in our TSDF network due to higher drum volumes, an increase in our wastewater treatment volumes and an increase due to the integration of a portion of the Safety-Kleen business into our Technical Services segment. The utilization rate at our incinerators was higher at 92.3% for the three months ended June 30, 2013, compared with 90.3% in the comparable period of 2012, and our landfill volumes increased by approximately 17% year-over-year.
The increases in Oil Re-refining and Recycling and SK Environmental Services revenues for the three months ended June 30, 2013 were due to our acquisition of Safety-Kleen in December 2012.
Industrial and Field Services revenues increased 21.6%, or $41.4 million, in the three months ended June 30, 2013 from the comparable period in 2012 primarily due to growth in the Oil sands region of Canada, increases in our field services business, high occupancy in our fixed lodges and positive contributions from several acquisitions.
Oil and Gas Field Services revenues decreased 10.0%, or $8.0 million, in the three months ended June 30, 2013 from the comparable period in 2012 primarily due to the lower rig count in Western Canada. We also experienced an early and extended spring break-up period and historic flooding in Western Canada during the second quarter of 2013 which resulted in certain project delays.
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, competitive industry pricing, and the effects of fuel prices on our fuel recovery fees. 
Cost of Revenues 
Technical Services cost of revenues increased 17.3%, or $28.4 million, in the three months ended June 30, 2013 from the comparable period in 2012 primarily due to increases in salary and labor expenses ($9.7 million), materials and supplies ($9.5 million), outside transportation ($6.7 million) and vehicle expense and equipment repair costs ($3.3 million), offset partially by a reduction in materials for reclaim ($9.2 million).  These increases relate partially to the integration of a portion of the Safety-Kleen business into the Technical Services segment.
The increases in Oil Re-refining and Recycling and SK Environmental Services cost of revenues for the three months ended June 30, 2013 were due to our acquisition of Safety-Kleen in December 2012.
Industrial and Field Services cost of revenues increased 19.8%, or $27.0 million, in the three months ended June 30, 2013 from the comparable period in 2012 primarily due to increased salary and labor expenses associated with acquisitions during 2012.  
Oil and Gas Field Services cost of revenues decreased 4.7%, or $3.1 million, in the three months ended June 30, 2013 from the comparable period in 2012 primarily due to costs related to a reduction in surface rentals activity and decreased seismic activities.
Corporate Items cost of revenues decreased $1.3 million, in the three months ended June 30, 2013 from the comparable period in 2012 primarily due to a reduction in health insurance costs offset partially by increased general insurance costs.
 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, 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. 
Selling, General and Administrative Expenses 
Technical Services selling, general and administrative expenses increased 9.9%, or $2.0 million, in the three months ended June 30, 2013 from the comparable period in 2012 primarily due to changes in environmental liabilities estimates.
The increases in Oil Re-refining and Recycling and SK Environmental Services selling, general and administrative expenses for the three months ended June 30, 2013 were due to our acquisition of Safety-Kleen in December 2012.
Industrial and Field Services selling, general and administrative expenses increased 5.7%, or $0.8 million, in the three months ended June 30, 2013 from the comparable period in 2012 primarily due to increased salaries and bonuses.

Table of Contents

Oil and Gas Field Services selling, general and administrative expenses decreased 12.7%, or $0.9 million, for the three months ended June 30, 2013, from the comparable period in 2012. The decrease was primarily due to decreased salaries and bonuses. 
Corporate Items selling, general and administrative expenses increased 93.0%, or $23.1 million, for the three months ended June 30, 2013, as compared to the same period in 2012 primarily due to our acquisition of Safety-Kleen in December 2012 resulting in increases in compensation costs, computer expenses, travel costs, professional fees and rent expense. We also incurred a year-over-year increase in severance costs of $1.4 million, and an increase in professional fees related to acquisitions of $3.2 million.

Interest expense, net increased $8.6 million in the second quarter of 2013 compared to the same period in 2012. The increase in interest expense was primarily due to the issuance of $800.0 million of 5.25% senior unsecured notes in July 2012 and $600.0 million of 5.125% senior unsecured notes in December 2012, which was partially offset by our redemption and repurchase during the third quarter of 2012 of $520.0 million of previously outstanding 7.625% senior secured notes. The transactions resulted in an additional principal amount of notes outstanding during 2012 than for the comparable prior period, but at a more favorable interest rate.

Table of Contents

(1)                     Corporate Items revenues and costs of revenues for the six months ended June 30, 2013 include one-time, non-cash reductions and increases of approximately $10.2 million and $3.4 million, respectively, due to the impact of fair value acquisition accounting adjustments on Safety-Kleen's historical deferred revenue, inventory and deferred cost balances at December 28, 2012.
(2)                     Items shown separately consist of (i) accretion of environmental liabilities and (ii) depreciation and amortization.
Revenues 
Technical Services revenues increased 12.3%, or $59.2 million, in the six months ended June 30, 2013 from the comparable period in 2012 primarily due to strong contributions from our projects business, growth in our TSDF network due to higher drum volumes, an increase in our wastewater treatment volumes and an increase due to the integration of a portion of the Safety-Kleen business into our Technical Services segment. The utilization rate at our incinerators was 90.6% for the six months ended June 30, 2013, compared with 90.0% in the comparable period of 2012, and our landfill volumes increased by approximately 5% year-over-year.
The increases in Oil Re-refining and Recycling and SK Environmental Services revenues for the six months ended June 30, 2013 were due to our acquisition of Safety-Kleen in December 2012.
Industrial and Field Services revenues increased 15.2%, or $58.1 million, in the six months ended June 30, 2013 from the comparable period in 2012 primarily due to growth in the Oil sands region of Canada, increases in our field services business, high occupancy in our fixed lodges and positive contributions from several acquisitions.
Oil and Gas Field Services revenues decreased 15.8%, or $36.2 million, in the six months ended June 30, 2013 from the comparable period in 2012 primarily due to the lower rig count in Western Canada that resulted in a reduction in surface rental activity, decreased seismic activities and a decline in the energy services business. We also experienced an early and extended spring break-up period and historic flooding in Western Canada during the second quarter of 2013 which resulted in certain project delays.
Corporate Items revenues decreased $11.8 million, in the six months ended June 30, 2013 from the comparable period in 2012 primarily due to inclusion of the impact of the fair value acquisition accounting adjustment on Safety-Kleen's historical deferred revenue balance at December 28, 2012 ($10.2 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, competitive industry pricing, and the effects of fuel prices on our fuel recovery fees. 
Cost of Revenues 
Technical Services cost of revenues increased 15.8%, or $50.6 million, in the six months ended June 30, 2013 from the comparable period in 2012 primarily due to increases in salary and labor expenses ($19.4 million), materials and supplies ($16.7 million), outside transportation ($10.7 million), outside disposal and rail costs ($5.8 million), subcontractor and temporary fees ($3.8 million), vehicle expenses and equipment repair costs ($4.0 million), and utilities costs ($3.2 million), offset partially by a reduction in materials for reclaim ($19.2 million).  These increases relate partially to the integration of a portion of the Safety-Kleen business into the Technical Services segment.
The increases in Oil Re-refining and Recycling and SK Environmental Services cost of revenues for the six months ended June 30, 2013 were due to our acquisition of Safety-Kleen in December 2012.
Industrial and Field Services cost of revenues increased 14.4%, or $40.2 million, in the six months ended June 30, 2013 from the comparable period in 2012 primarily due to increased salary and labor expenses associated with acquisitions during 2012.  
Oil and Gas Field Services cost of revenues decreased 10.9%, or $17.8 million, in the six months ended June 30, 2013 from the comparable period in 2012 primarily due to costs related to a reduction in surface rentals activity, decreased seismic activities and a reduction in the energy services business.
Corporate Items cost of revenues increased $6.1 million, in the six months ended June 30, 2013 from the comparable period in 2012 primarily due to the impact of the acquisition accounting adjustments on Safety-Kleen's historical inventory and deferred cost balances at December 28, 2012 ($3.4 million) as well as increases in compensation costs and general insurance costs offset partially by a reduction in health insurance costs.
 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,

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. 
Selling, General and Administrative Expenses 
Technical Services selling, general and administrative expenses decreased 1.0%, or $0.4 million, in the six months ended June 30, 2013 from the comparable period in 2012 primarily due to decreased incentive compensation.
The increases in Oil Re-refining and Recycling and SK Environmental Services selling, general and administrative expenses for the six months ended June 30, 2013 were due to our acquisition of Safety-Kleen in December 2012.
Industrial and Field Services selling, general and administrative expenses increased 6.6%, or $1.9 million, in the six months ended June 30, 2013 from the comparable period in 2012 primarily due to increased salaries and bonuses. 
Oil and Gas Field Services selling, general and administrative expenses decreased 10.5%, or $1.7 million, for the six months ended June 30, 2013, from the comparable period in 2012. The decrease was primarily due to decreases in salaries and bonuses. 
Corporate Items selling, general and administrative expenses increased 98.2%, or $47.9 million, for the six months ended June 30, 2013, as compared to the same period in 2012 primarily due to our acquisition of Safety-Kleen in December 2012 resulting in increases in compensation costs, computer expenses, travel costs, professional fees and rent expense. We also incurred a year-over-year increase in severance costs of $3.9 million and an increase in professional fees related to acquisitions of $5.3 million.

Depreciation and amortization increased 68.9%, or $52.0 million, in the first six months of 2013 compared to the same period in 2012. Depreciation of fixed assets increased primarily due to acquisitions and other increased capital expenditures in recent periods. Landfill and other amortization increased primarily due to the increase in other intangibles resulting from recent acquisitions.

Interest expense, net increased $17.2 million in the first six months of 2013 compared to the same period in 2012. The increase in interest expense was primarily due to the issuance of $800.0 million of 5.25% senior unsecured notes in July 2012 and $600.0 million of 5.125% senior unsecured notes in December 2012, which was partially offset by our redemption and repurchase during the third quarter of 2012 of $520.0 million of previously outstanding 7.625% senior secured notes. The transactions resulted in an additional principal amount of notes outstanding during 2012 than for the comparable prior period, but at a more favorable interest rate.
Income Taxes 
Our effective tax rate for the three and six months ended June 30, 2013 was 35.1% and 34.2%, respectively, compared to 35.8% and 36.0% for the same periods in 2012. The decrease in the effective tax rate for the three and six months ended June 30, 2013 was primarily attributable to lower accrued interest and penalties related to unrecognized tax benefits in 2013 as compared to the same period for 2012.

41

Table of Contents

Income tax expense for the three months ended June 30, 2013 decreased $0.7 million to $12.4 million from $13.1 million for the comparable period in 2012. Income tax expense for the six months ended June 30, 2013 decreased $13.8 million to $17.4 million from $31.2 million for the comparable period in 2012. The decreased tax expense for the three and six months ended June 30, 2013 was primarily attributable to lower income before taxes.
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 June 30, 2013 and December 31, 2012, we had a remaining valuation allowance of $25.6 million. The allowance as of June 30, 2013 and December 31, 2012 consisted of $17.6 million of foreign tax credits, $1.4 million of state net operating loss carryforwards and $6.6 million of foreign net operating loss carryforwards.  
Our accounting 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 and related reserves as of June 30, 2013 and December 31, 2012, included accrued interest of $1.5 million and $1.4 million, respectively.  Tax expense for each of the three and six months ended June 30, 2013 included interest of $0.1 million. Tax expense for each of the three and six months ended June 30, 2012 included interest of $0.7 million and $1.4 million, respectively.
Liquidity and Capital Resources 
Cash and Cash Equivalents 
During the six months ended June 30, 2013, cash and cash equivalents increased $33.6 million.
We intend to use our existing cash and cash equivalents, marketable securities and cash flow from operations to provide for our working capital needs, to fund capital expenditures and for potential acquisitions. 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.  
At June 30, 2013, cash and cash equivalents totaled $263.5 million, compared to $229.8 million at December 31, 2012. At June 30, 2013, cash and cash equivalents held by foreign subsidiaries totaled $48.0 million and were readily convertible into other foreign currencies including U.S. dollars. At June 30, 2013, the cash and cash equivalent balances for our U.S. operations were $215.4 million. Our U.S. operations had net operating cash from operations of $47.8 million for the six months ended June 30, 2013. Additionally, we have available a $400.0 million revolving credit facility of which $262.5 million was available to borrow at June 30, 2013. Based on the above and on our current plans, we believe that our U.S. operations have adequate financial resources to satisfy their liquidity needs without being required to repatriate earnings from foreign subsidiaries. Accordingly, although repatriation to the U.S. of foreign earnings would generally be subject to U.S. income taxation, net of any available foreign tax credits, we have not recorded any deferred tax liability related to such repatriation since we intend to permanently reinvest foreign earnings outside the U.S.
We had accrued environmental liabilities as of June 30, 2013 of approximately $218.3 million, substantially all of which we assumed in connection with our acquisition of the CSD assets in September 2002, Teris LLC in 2006, one of the two solvent recycling facilities we purchased from Safety-Kleen Systems, Inc. in 2008, and the remaining Safety-Kleen facilities acquired as part of our acquisition of Safety-Kleen in 2012. 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 six months ended June 30, 2013  
Cash from operating activities in the first six months of 2013 was $137.6 million, a decrease of 21.7%, or $38.2 million, compared with cash from operating activities in the first six months of 2012. The change was primarily the result of a higher investment in net working capital offset partially by and increase in depreciation expense.

Table of Contents

Cash used for investing activities in the first six months of 2013 was $141.4 million, an increase of 10.1%, or $13.0 million, compared with cash used for investing activities in the first six months of 2012.  The change was due primarily from an increase in capital expenditures of $58.5 million.  
Cash from financing activities in the first six months of 2013 was $40.0 million, compared with cash used for financing activities of $10.3 million in the first six months of 2012. The improvement was primarily the result of an increase in uncashed checks.  
Cash Flows for the six months ended June 30, 2012
     Cash from operating activities in the first six months of 2012 was $175.8 million, an increase of 132.4%, or $100.1 million, compared with cash from operating activities in the first six months of 2011. The change was primarily the result of a net decrease in working capital items. 
Cash used for investing activities in the first six months of 2012 was $128.5 million, a decrease of 51.9% or $138.7 million, compared with cash used for investing activities in the first six months of 2011.  The change was due primarily from lower year-over-year costs associated with acquisitions offset partially by increases in additions to property, plant and equipment. 
Cash used for financing activities in the first six months of 2012 was $10.3 million, compared with cash from financing activities of $265.5 million in the first six months of 2011. The change was primarily the result of the issuance of $250.0 million aggregate principal amount of 7.625% senior secured notes on March 24, 2011.
Financing Arrangements 
The financing arrangements and principal terms of our $800.0 million principal amount of 5.25% senior unsecured notes due 2020 and $600.0 million principal amount of 5.125% senior unsecured notes due 2021 which were outstanding at June 30, 2013, and our amended $400.0 million revolving credit facility, are discussed further in Note 11, “Financing Arrangements,” in our Annual Report on Form 10-K for the year ended December 31, 2012.
 As of June 30, 2013, we were in compliance with the covenants of our debt agreements, and we believe it is reasonably likely that we will continue to meet such covenants. 
Liquidity Impacts of Uncertain Tax Positions 
As discussed in Note 12, “Income Taxes,” to our financial statements included in Item 1 of this report, we have recorded as of June 30, 2013, $3.9 million of unrecognized tax benefits and related reserves and $1.5 million of potential interest. These liabilities are classified as “deferred taxes, 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 June 30, 2013, our long-term investments included $4.4 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.  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 June 30, 2013, 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 an adjustment 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 June 30, 2013 (in thousands):

In addition to the fixed rate borrowings described in the above table, we had at June 30, 2013 variable rate instruments that included a revolving credit facility (as amended and restated on January 17, 2013) with maximum borrowings of up to $400.0 million (with a $325.0 million sub-limit for letters of credit). Commencing in 2013, we began remitting interest payments in the amount of $21.0 million each related to the $800.0 million senior unsecured notes payable semi-annually on February 1 and August 1 of each year, and began remitting interest payments in the amount of $15.4 million each related to the $600.0 million senior unsecured notes payable semi-annually on June 1 and December 1 of each year. 
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 2013, the Canadian subsidiaries transacted approximately 6.8% 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 $1.2 million and $0.3 million for the three months ended June 30, 2013 and 2012, 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 $0.1 million and $1.3 million for the six months ended June 30, 2013 and 2012, respectively. 
At June 30, 2013, $4.4 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. 
In connection with the operations of our Technical Services, SK Environmental Services, Industrial and Field Services and Oil and Gas Field Services segments, 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. In connection with the operations of our Oil Re-refining and Recycling segment, which we acquired in December 2012 as part of our acquisition of Safety-Kleen, we are exposed to market risk from changes in certain oil and oil derivative commodity prices and indices, specifically the ICIS-LOR rate and 6-oil index. Safety-Kleen entered into several commodity derivatives during 2012 and 2013 which are comprised of cashless collar contracts related to crude oil prices. Pursuant to each such contract, Safety-Kleen sold a call option to a bank and then purchased a put option from the same bank in order to manage against significant fluctuations in crude oil prices, which are closely correlated with the ICIS-LOR rate and the 6-oil index. These commodity derivatives are designed to mitigate, although not eliminate, our exposure to declines in these oil indices below a price floor, but they also will limit our potential upside related to increases in these oil indices above a price cap. We do not believe that our exposure will be material. These commodity derivatives are not classified as hedges and expire at various intervals in 2013 and 2014. For additional information, see Note 4, "Fair Value Measurements" in this report and Note 2, “Significant Accounting Policies - Derivative Financial Instruments,” to our consolidated financial statements included in Item 8, “Financial Statements and Supplementary Data,” in our Annual Report on Form 10-K for the year ended December 31, 2012.

ITEM 4.                             CONTROLS AND PROCEDURES
 
Evaluation of Disclosure Controls and Procedures
 
Based on an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, as of the end of the period covered by this Quarterly Report on 10-Q, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) were effective as of June 30, 2013 to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms and is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.
 
Changes in Internal Control over Financial Reporting
     
On December 28, 2012, the Company acquired Safety-Kleen (see Note 3, "Business Combinations,” to the financial statements included in Item 1 of this report). The Company has extended its Section 404 compliance program under the Sarbanes-Oxley Act of 2002 and the applicable rules and regulations under such Act to include Safety-Kleen. The Company will report on its assessment of the effectiveness of internal control over financial reporting for the combined operations at December 31, 2013.
Other than as described above, there were no changes in the Company’s internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Exchange Act Rules 13a-15 or 15d-15 that was conducted during the quarter ending June 30, 2013 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
