GENERAL
GENERAL	NOTE 1. GENERAL Basis of Presentation The accompanying unaudited consolidated financial statements include the results of operations, financial position and cash flows of US Ecology, Inc. and its wholly-owned subsidiaries. All significant intercompany balances have been eliminated. Throughout these financial statements words such as “we,” “us,” “our,” “US Ecology” and the “Company” refer to US Ecology, Inc. and its subsidiaries. In the opinion of management, the accompanying unaudited consolidated financial statements include all adjustments necessary to present fairly, in all material respects, the results of the Company for the periods presented. These consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) have been omitted pursuant to the rules and regulations of the SEC. These consolidated financial statements should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014. The results for the three and six months ended June 30, 2015 are not necessarily indicative of results to be expected for the entire fiscal year. In these consolidated financial statements, certain amounts in prior periods’ consolidated financial statements have been reclassified to conform with the current period presentation. The Company’s Consolidated Balance Sheet as of December 31, 2014 has been derived from the Company’s audited Consolidated Balance Sheet as of that date and has been revised for purchase price measurement period adjustments related to the acquisition of EQ as disclosed in Note 2. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from the estimates and assumptions that we use in the preparation of our financial statements. As it relates to estimates and assumptions in amortization rates and environmental obligations, significant engineering, operations and accounting judgments are required. We review these estimates and assumptions no less than annually. In many circumstances, the ultimate outcome of these estimates and assumptions will not be known for decades into the future. Actual results could differ materially from these estimates and assumptions due to changes in applicable regulations, changes in future operational plans and inherent imprecision associated with estimating environmental impacts far into the future. Recently Issued Accounting Pronouncements In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-03 Simplifying the Presentation of Debt Issuance Costs . This ASU requires an entity to present debt issuance costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. The guidance is effective for annual and interim reporting periods beginning after December 15, 2015. We do not believe the adoption of this update will have a material effect on our financial position and results of operations. In May 2014, the FASB issued ASU No. 2014-09 Revenue from Contracts with Customers , which provides guidance for revenue recognition. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The standard permits the use of either the retrospective or cumulative effect transition method. The ASU also requires enhanced disclosures regarding the nature, amount, timing, and uncertainty of revenues and cash flows from contracts with customers. On July 9, 2015, the FASB agreed to delay the effective date of ASU 2014-09 by one year. The new guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early adoption is permitted but not before annual periods beginning after December 15, 2016. We are currently assessing the impact the adoption of ASU 2014-09 may have on our consolidated financial statements.

BUSINESS COMBINATION
BUSINESS COMBINATION	NOTE 2. BUSINESS COMBINATION On June 17, 2014, the Company acquired 100% of the outstanding shares of EQ Holdings, Inc. and its wholly-owned subsidiaries (collectively “EQ”). EQ is a fully integrated environmental services company providing waste treatment and disposal, wastewater treatment, remediation, recycling, industrial cleaning and maintenance, transportation, total waste management, technical services, and emergency response services to a variety of industries and customers in North America. The total purchase price was $460.9 million, net of cash acquired, and was funded through a combination of cash on hand and borrowings under a new $415.0 million term loan. As of June 30, 2015, the Company finalized the purchase accounting for the acquisition of EQ. The following table summarizes the consideration paid for EQ and the fair value estimates of assets acquired and liabilities assumed recognized at the acquisition date, with purchase price allocation adjustments since the preliminary purchase price allocation as previously disclosed as of December 31, 2014: Purchase Price Allocation $s in thousands As Reported in Form 10-K Adjustments As Retrospectively Adjusted Current assets $ $ $ Property and equipment — Identifiable intangible assets — Current liabilities ) ) ) Other liabilities ) ) Total identifiable net assets ) Goodwill Total purchase price $ $ — $ Purchase price allocation adjustments related primarily to the receipt of additional information regarding the fair values of income taxes payable and receivable, deferred income taxes and residual goodwill. Goodwill of $197.6 million arising from the acquisition is the result of several factors. EQ has an assembled workforce that serves the U.S. industrial market utilizing state-of-the-art technology to treat a wide range of industrial and hazardous waste. The acquisition of EQ increases our geographic base providing a coast-to-coast presence and an expanded service platform to better serve key North American hazardous waste markets. In addition, the acquisition of EQ provides us with an opportunity to compete for additional waste clean-up project work; expand penetration with national accounts; improve and enhance transportation, logistics, and service offerings with existing customers and attract new customers. $132.4 million of the goodwill recognized was allocated to reporting units in our Environmental Services segment and $65.2 million of the goodwill recognized was allocated to reporting units in our Field & Industrial Services segment. None of the goodwill recognized is expected to be deductible for income tax purposes. The fair value estimate of identifiable intangible assets by major intangible asset class and related weighted average amortization period are as follows: $s in thousands Fair Value Weighted Average Amortization Period (Years) Customer relationships $ 15 Permits and licenses 45 Permits and licenses, nonamortizing — Tradename 3 Customer backlog 10 Developed software 9 Non-compete agreements 1 Internet domain and website 19 Database 15 Total identifiable intangible assets $ The following unaudited pro forma financial information presents the combined results of operations as if EQ had been combined with us at the beginning of each of the periods presented. The pro forma financial information includes the accounting effects of the business combination, including the amortization of intangible assets, depreciation of property, plant and equipment, and interest expense. The unaudited pro forma financial information is presented for informational purposes only and is not indicative of the results of operations that would have been achieved if the acquisition had taken place at the beginning of the periods presented, nor should it be taken as indication of our future consolidated results of operations.

Changes in fair value of the swap recognized in AOCI are reclassified to interest expense when hedged interest payments on the underlying debt are made. Amounts in AOCI expected to be recognized in interest expense over the next 12 months total approximately $3.5 million ($2.3 million after tax).

FAIR VALUE MEASUREMENTS
FAIR VALUE MEASUREMENTS	NOTE 6. FAIR VALUE MEASUREMENTS Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities recorded at fair value are categorized using defined hierarchical levels directly related to the amount of subjectivity associated with the inputs to fair value measurements, as follows: Level 1 - Quoted prices in active markets for identical assets or liabilities; Level 2 - Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable; Level 3 - Unobservable inputs in which little or no market activity exists, requiring an entity to develop its own assumptions that market participants would use to value the asset or liability. The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, restricted cash and investments, accounts payable, accrued liabilities, debt and interest rate swap agreements. The estimated fair value of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their carrying value due to the short-term nature of these instruments. The Company estimates the fair value of its variable-rate debt using Level 2 inputs, such as interest rates, related terms and maturities of similar obligations. The fair value of the Company’s debt approximated its carrying amount as of June 30, 2015. The Company’s assets and liabilities measured at fair value on a recurring basis consisted of the following: June 30, 2015 Quoted Prices in Active Markets Other Observable Inputs Unobservable Inputs $s in thousands (Level 1) (Level 2) (Level 3) Total Assets: Fixed-income securities (1) $ $ $ — $ Money market funds (2) — — Total $ $ $ — $ Liabilities: Interest rate swap agreement (3) $ — $ $ — $ Total $ — $ $ — $ December 31, 2014 Quoted Prices in Active Markets Other Observable Inputs Unobservable Inputs $s in thousands (Level 1) (Level 2) (Level 3) Total Assets: Fixed-income securities (1) $ $ $ — $ Money market funds (2) — — Total $ $ $ — $ Liabilities: Interest rate swap agreement (3) $ — $ $ — $ Total $ — $ $ — $ (1) We invest a portion of our Restricted cash and investments in fixed-income securities, including U.S. Treasury and U.S. agency securities. We measure the fair value of U.S. Treasury securities using quoted prices for identical assets in active markets. We measure the fair value of U.S. agency securities using observable market activity for similar assets. The fair value of our fixed-income securities approximates our cost basis in the investments. (2) We invest a portion of our Restricted cash and investments in money market funds. We measure the fair value of these money market fund investments using quoted prices for identical assets in active markets. (3) In order to manage interest rate exposure, we entered into an interest rate swap agreement in October 2014 that effectively converts a portion of our variable-rate debt to a fixed interest rate. The swap is designated as a cash flow hedge, with gains and losses deferred in other comprehensive income to be recognized as an adjustment to interest expense in the same period that the hedged interest payments affect earnings. The interest rate swap has an effective date of December 31, 2014 in an initial notional amount of $250.0 million. The fair value of the interest rate swap agreement represents the difference in the present value of cash flows calculated (i) at the contracted interest rates and (ii) at current market interest rates at the end of the period. We calculate the fair value of interest rate swap agreements quarterly based on the quoted market price for the same or similar financial instruments. The fair value of the interest rate swap agreement is included in Other long-term liabilities in the Company’s consolidated balance sheet.

(“Allstate”) subsidiary to a private investor group for approximately $58.0 million cash, subject to adjustments for working capital and capital expenditures. Allstate represents the majority of the industrial services business we acquired with the acquisition of EQ. As a result of this agreement and management’s strategic review, we evaluated the recoverability of the assets associated with our industrial services business. Based on this analysis, we recorded a non-cash goodwill impairment charge of $6.7 million, or $0.31 per diluted share, in the second quarter of 2015.

Upon entering into the Credit Agreement, the Company terminated its existing credit agreement with Wells Fargo, dated October, 29, 2010, as amended (the “Former Agreement”). Immediately prior to the termination of the Former Agreement, there were no outstanding borrowings under the Former Agreement. No early termination penalties were incurred as a result of the termination of the Former Agreement. Term Loan The Term Loan provides an initial commitment amount of $415.0 million, the proceeds of which were used to acquire 100% of the outstanding shares of EQ and pay related transaction fees and expenses. The Term Loan bears interest at a base rate (as defined in the Credit Agreement) plus 2.00% or LIBOR plus 3.00%, at the Company’s option. The Term Loan is subject to amortization in equal quarterly installments in an aggregate annual amount equal to 1.00% of the original principal amount of the Term Loan. At June 30, 2015, the effective interest rate on the Term Loan, including the impact of our interest rate swap, was 4.66%. Interest only payments are due either monthly or on the last day of any interest period, as applicable. As set forth in the Credit Agreement, the Company is required to enter into one or more interest rate hedge agreements in amounts sufficient to fix the interest rate on at least 50% of the principal amount of the $415.0 million Term Loan. In October 2014, the Company entered into an interest rate swap agreement with Wells Fargo, effectively fixing the interest rate on $245.0 million, or 68%, of the Term Loan principal outstanding as of June 30, 2015. Revolving Credit Facility The Revolving Credit Facility provides up to $125.0 million of revolving credit loans or letters of credit with the use of proceeds restricted solely for working capital and other general corporate purposes. Under the Revolving Credit Facility, revolving loans are available based on a base rate (as defined in the Credit Agreement) or LIBOR, at the Company’s option, plus an applicable margin which is determined according to a pricing grid under which the interest rate decreases or increases based on our ratio of funded debt to earnings before interest, taxes, depreciation and amortization (“EBITDA”). The Company is required to pay a commitment fee of 0.50% per annum on the unused portion of the Revolving Credit Facility, with such commitment fee to be reduced based upon the Company’s total leverage ratio as defined in the Credit Agreement. The maximum letter of credit capacity under the new revolving credit facility is $50.0 million and the Credit Agreement provides for a letter of credit fee equal to the applicable margin for LIBOR loans under the Revolving Credit Facility. Interest only payments are due either monthly or on the last day of any interest period, as applicable. At June 30, 2015, there were no borrowings outstanding on the Revolving Credit Facility. The availability under the Revolving Credit Facility was $119.5 million with $5.5 million of the Revolving Credit Facility issued in the form of standby letters of credit utilized as collateral for closure and post-closure financial assurance and other assurance obligations. Except as set forth below, the Company may prepay the Term Loan or permanently reduce the Revolving Credit Facility commitment under the Credit Agreement at any time without premium or penalty (other than customary “breakage” costs with respect to the early termination of LIBOR loans). On or prior to six months after the closing of the Credit Agreement, if we prepay the initial term loans or amend the pricing terms of the initial term loans, in each case in connection with a reduction of the effective yield, we are required to pay a 1% prepayment premium (unless in connection with a change of control, sale or permitted acquisition). Subject to certain exceptions, the Credit Agreement provides for mandatory prepayment upon certain asset dispositions, casualty events and issuances of indebtedness. The Credit Agreement is also subject to mandatory annual prepayments commencing in December 2015 if our total leverage (defined as the ratio of our consolidated funded debt as of the last day of the applicable fiscal year to our adjusted EBITDA for such period) exceeds certain ratios as follows: 50% of our adjusted excess cash flow (as defined in the Credit Agreement and which takes into account certain adjustments) if our total leverage ratio is greater than 2.50 to 1.00, with step-downs to 0% if our total leverage ratio is equal to or less than 2.50 to 1.00. Pursuant to (i) an unconditional guarantee agreement (the “Guarantee”) and (ii) a collateral agreement (the “Collateral Agreement”), each entered into by the Company and its domestic subsidiaries on June 17, 2014, the Company’s obligations under the Credit Agreement are jointly and severally and fully and unconditionally guaranteed on a senior basis by all of the Company’s existing and certain future domestic subsidiaries and the Credit Agreement is secured by substantially all of the Company’s and its domestic subsidiaries’ assets except the Company’s and its domestic subsidiaries’ real property. The Credit Agreement contains customary restrictive covenants, subject to certain permitted amounts and exceptions, including covenants limiting the ability of the Company to incur additional indebtedness, pay dividends and make other restricted payments, repurchase shares of our outstanding stock and create certain liens. We may only declare quarterly or annual dividends if on the date of declaration, no event of default has occurred and no other event or condition has occurred that would constitute default due to the payment of the dividend. The Credit Agreement also contains a financial maintenance covenant, which is a maximum Consolidated Senior Secured Leverage Ratio, as defined in the Credit Agreement, and is only applicable to the Revolving Credit Facility. Our Consolidated Senior Secured Leverage Ratio as of the last day of any fiscal quarter, commencing with June 30, 2014, may not exceed the ratios indicated below: Fiscal Quarters Ending Maximum Ratio June 30, 2014 through September 30, 2015 4.00 to 1.00 December 31, 2015 through September 30, 2016 3.75 to 1.00 December 31, 2016 through September 30, 2017 3.50 to 1.00 December 31, 2017 through September 30, 2018 3.25 to 1.00 December 31, 2018 and thereafter 3.00 to 1.00 At June 30, 2015, we were in compliance with all of the financial covenants in the Credit Agreement.

EQUITY
EQUITY	NOTE 13. EQUITY Omnibus Incentive Plan On May 27, 2015, our stockholders approved the Omnibus Incentive Plan (“Omnibus Plan”), which was approved by our Board of Directors on April 7, 2015. The Omnibus Plan provides, among other things, the ability for the Company to grant restricted stock, performance stock, options, stock appreciation rights (“SARs”), restricted stock units (“RSUs”), performance stock units (“PSUs”) and other stock-based awards or cash awards to officers, employees, consultants and non-employee directors. We will cease to grant equity awards under our 2008 Stock Option Incentive Plan and our 2006 Restricted Stock Plan (“Previous Plans”), and the Previous Plans will remain in effect solely for the settlement of awards granted under the Previous Plans. No shares that are reserved but unissued under the Previous Plans or that are outstanding under the Previous Plans and reacquired by the Company for any reason will be available for issuance under the Omnibus Plan. The Omnibus Plan expires on April 7, 2025 and authorizes 1.5 million shares of common stock for grant over the life of the Omnibus Plan. Performance Stock Units On May 27, 2015, the Company granted 6,929 PSUs to the Company’s named executive officers. Each PSU represents the right to receive, on the settlement date, one share of the Company’s common stock. The total number of PSUs each participant is eligible to earn ranges from 0% to 200% of the target number of PSUs granted. The actual number of PSUs that will vest and be settled in shares is determined at the end of a three-year performance period beginning January 1, 2015, based on total stockholder return relative to a set of peer companies. The fair value of the PSUs estimated on the grant date using a Monte Carlo simulation was $65.78 per unit. Compensation expense is recorded over the awards’ vesting period. The following table presents the range of assumptions used in the Monte Carlo simulation to calculate the fair value of the PSUs granted on May 27, 2015: Expected volatility % Stock price on grant date $ Risk-free interest rate % Expected term (years) Expected dividend yield % Stock Options and Restricted Stock During the six months ended June 30, 2015, option holders exercised 43,009 options with a weighted-average exercise price of $24.94 per option. Option holders exercised 1,042 of these options via net share settlement. During the six months ended June 30, 2015, the Company issued 5,811 shares of restricted stock from our treasury stock at an average cost of $46.82 per share.

OPERATING SEGMENTS
OPERATING SEGMENTS	NOTE 15. NOTE 15. OPERATING SEGMENTS Financial Information by Segment Our operations are managed in two reportable segments reflecting our internal reporting structure and nature of services offered as follows: Environmental Services - This segment includes all of the legacy US Ecology operations and the legacy EQ treatment and disposal facilities. It provides a broad range of hazardous material management services including transportation, recycling, treatment and disposal of hazardous and non-hazardous waste at Company-owned landfill, wastewater and other treatment facilities. Field & Industrial Services - This segment includes all of the field and industrial service business of the legacy EQ operation. It provides packaging and collection of hazardous waste and total waste management solutions at customer sites and through our 10-day transfer facilities. Services include on-site management, waste characterization, transportation and disposal of non-hazardous and hazardous waste. This segment also provides specialty services such as high-pressure and chemical cleaning, centrifuge and materials processing, tank cleaning, decontamination, remediation, transportation, spill cleanup and emergency response and other services to commercial and industrial facilities and to government entities. The operations not managed through our two reportable segments are recorded as “Corporate.” Corporate selling, general and administrative expenses include typical corporate items such as legal, accounting and other items of a general corporate nature. Income taxes are assigned to Corporate, but all other items are included in the segment where they originated. Inter-company transactions have been eliminated from the segment information and are not significant between segments. Summarized financial information of our reportable segments is as follows: Three Months Ended June 30, 2015 $s in thousands Environmental Services Field & Industrial Services Corporate Total Treatment & Disposal Revenue $ $ — $ — $ Services Revenue: Transportation and Logistics (1) — Industrial Cleaning (2) — — Technical Services (3) — — Remediation (4) — — Other (5) — — Total Revenue $ $ $ — $ Depreciation, amortization and accretion $ $ $ $ Capital expenditures $ $ $ $ Total assets $ $ $ $ Three Months Ended June 30, 2014 $s in thousands Environmental Services Field & Industrial Services Corporate Total Treatment & Disposal Revenue $ $ — $ — $ Services Revenue: Transportation and Logistics (1) — Industrial Cleaning (2) — — Technical Services (3) — — Remediation (4) — — Other (5) — — Total Revenue $ $ $ — $ Depreciation, amortization and accretion $ $ $ $ Capital expenditures $ $ $ $ Total assets $ $ $ $ Six Months Ended June 30, 2015 $s in thousands Environmental Services Field & Industrial Services Corporate Total Treatment & Disposal Revenue $ $ — $ — $ Services Revenue: Transportation and Logistics (1) — Industrial Cleaning (2) — — Technical Services (3) — — Remediation (4) — — Other (5) — — Total Revenue $ $ $ — $ Depreciation, amortization and accretion $ $ $ $ Capital expenditures $ $ $ $ Total assets $ $ $ $ Six Months Ended June 30, 2014 $s in thousands Environmental Services Field & Industrial Services Corporate Total Treatment & Disposal Revenue $ $ — $ — $ Services Revenue: Transportation and Logistics (1) — Industrial Cleaning (2) — — Technical Services (3) — — Remediation (4) — — Other (5) — — Total Revenue $ $ $ — $ Depreciation, amortization and accretion $ $ $ $ Capital expenditures $ $ $ $ Total assets $ $ $ $ (1) Includes such services as collection, transportation and disposal of non-hazardous and hazardous waste.

(3) Includes such services as Total Waste Management (“TWM”) programs, retail services, laboratory packing, less-than-truck-load (LTL) service and Household Hazardous Waste (“HHW”) collection. (4) Includes such services as site assessment, onsite treatment, project management and remedial action planning and execution. (5) Includes such services as emergency response and marine. Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization (“Adjusted EBITDA”) The primary financial measure used by management to assess segment performance is Adjusted EBITDA. Adjusted EBITDA is defined as net income before net interest expense, income tax expense, depreciation, amortization, stock based compensation, accretion of closure and post-closure liabilities, foreign currency gain/loss, non-cash impairment charges and other income/expense, which are not considered part of usual business operations. Adjusted EBITDA is a complement to results provided in accordance with accounting principles generally accepted in the United States (“GAAP”) and we believe that such information provides additional useful information to analysts, stockholders and other users to understand the Company’s operating performance. Since Adjusted EBITDA is not a measurement determined in accordance with GAAP and is thus susceptible to varying calculations, Adjusted EBITDA as presented may not be comparable to other similarly titled measures of other companies. Items excluded from Adjusted EBITDA are significant components in understanding and assessing our financial performance. Adjusted EBITDA should not be considered in isolation or as an alternative to, or substitute for, net income, cash flows generated by operations, investing or financing activities, or other financial statement data presented in the consolidated financial statements as indicators of financial performance or liquidity. Adjusted EBITDA has limitations as an analytical tool and should not be considered in isolation or a substitute for analyzing our results as reported under GAAP. Some of the limitations are:  Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs;  Adjusted EBITDA does not reflect our interest expense, or the requirements necessary to service interest or principal payments on our debt;  Adjusted EBITDA does not reflect our income tax expenses or the cash requirements to pay our taxes;  Adjusted EBITDA does not reflect our cash expenditures or future requirements for capital expenditures or contractual commitments; and  Although depreciation and amortization charges are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and Adjusted EBITDA does not reflect any cash requirements for such replacements. A reconciliation of Adjusted EBITDA to Net Income is as follows: Three Months Ended June 30, Six Months Ended June 30, $s in thousands 2015 2014 2015 2014 Adjusted EBITDA: Environmental Services $ $ $ $ Field & Industrial Services Corporate ) ) ) ) Total Reconciliation to Net income: Income tax expense ) ) ) ) Interest expense ) ) ) ) Interest income Foreign currency gain (loss) ) ) Other income Impairment charges ) — ) — Depreciation and amortization of plant and equipment ) ) ) ) Amortization of intangibles ) ) ) ) Stock-based compensation ) ) ) ) Accretion and non-cash adjustment of closure & post-closure liabilities ) ) ) ) Net income $ $ $ $ Revenue, Property and Equipment and Intangible Assets Outside of the United States We provide services in the United States and Canada.

The dividend was paid using cash on hand on July 28, 2015 in an aggregate amount of $3.9 million. Definitive Agreement On August 4, 2015, we entered into a definitive agreement to sell our Allstate Power Vac., Inc. (“Allstate”) subsidiary to a private investor group for approximately $58.0 million cash, subject to adjustments for working capital and capital expenditures. The transaction is subject to customary closing conditions and is expected to close in the fourth quarter of 2015, with the cash proceeds from the transaction expected to be used to repay indebtedness. Allstate represents the majority of the industrial services business we acquired with the acquisition of EQ. As a result of this agreement and management’s strategic review, we evaluated the recoverability of the assets associated with our industrial services business. Based on this analysis, we recorded a non-cash goodwill impairment charge of $6.7 million, or $0.31 per diluted share, in the second quarter of 2015.

Basis of presentation	Basis of Presentation The accompanying unaudited consolidated financial statements include the results of operations, financial position and cash flows of US Ecology, Inc. and its wholly-owned subsidiaries. All significant intercompany balances have been eliminated. Throughout these financial statements words such as “we,” “us,” “our,” “US Ecology” and the “Company” refer to US Ecology, Inc. and its subsidiaries. In the opinion of management, the accompanying unaudited consolidated financial statements include all adjustments necessary to present fairly, in all material respects, the results of the Company for the periods presented. These consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) have been omitted pursuant to the rules and regulations of the SEC. These consolidated financial statements should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014. The results for the three and six months ended June 30, 2015 are not necessarily indicative of results to be expected for the entire fiscal year. In these consolidated financial statements, certain amounts in prior periods’ consolidated financial statements have been reclassified to conform with the current period presentation. The Company’s Consolidated Balance Sheet as of December 31, 2014 has been derived from the Company’s audited Consolidated Balance Sheet as of that date and has been revised for purchase price measurement period adjustments related to the acquisition of EQ as disclosed in Note 2.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from the estimates and assumptions that we use in the preparation of our financial statements. As it relates to estimates and assumptions in amortization rates and environmental obligations, significant engineering, operations and accounting judgments are required. We review these estimates and assumptions no less than annually. In many circumstances, the ultimate outcome of these estimates and assumptions will not be known for decades into the future. Actual results could differ materially from these estimates and assumptions due to changes in applicable regulations, changes in future operational plans and inherent imprecision associated with estimating environmental impacts far into the future.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-03 Simplifying the Presentation of Debt Issuance Costs . This ASU requires an entity to present debt issuance costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. The guidance is effective for annual and interim reporting periods beginning after December 15, 2015. We do not believe the adoption of this update will have a material effect on our financial position and results of operations. In May 2014, the FASB issued ASU No. 2014-09 Revenue from Contracts with Customers , which provides guidance for revenue recognition. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The standard permits the use of either the retrospective or cumulative effect transition method. The ASU also requires enhanced disclosures regarding the nature, amount, timing, and uncertainty of revenues and cash flows from contracts with customers. On July 9, 2015, the FASB agreed to delay the effective date of ASU 2014-09 by one year. The new guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early adoption is permitted but not before annual periods beginning after December 15, 2016. We are currently assessing the impact the adoption of ASU 2014-09 may have on our consolidated financial statements.

(2) We invest a portion of our Restricted cash and investments in money market funds. We measure the fair value of these money market fund investments using quoted prices for identical assets in active markets. (3) In order to manage interest rate exposure, we entered into an interest rate swap agreement in October 2014 that effectively converts a portion of our variable-rate debt to a fixed interest rate. The swap is designated as a cash flow hedge, with gains and losses deferred in other comprehensive income to be recognized as an adjustment to interest expense in the same period that the hedged interest payments affect earnings. The interest rate swap has an effective date of December 31, 2014 in an initial notional amount of $250.0 million. The fair value of the interest rate swap agreement represents the difference in the present value of cash flows calculated (i) at the contracted interest rates and (ii) at current market interest rates at the end of the period. We calculate the fair value of interest rate swap agreements quarterly based on the quoted market price for the same or similar financial instruments. The fair value of the interest rate swap agreement is included in Other long-term liabilities in the Company’s consolidated balance sheet.
