Accounting Policies [Abstract]
Basis of Presentation	BASIS OF PRESENTATION Republic Services, Inc., a Delaware corporation, and its consolidated subsidiaries (also referred to collectively as "Republic", "the Company", "we", "us", or "our"), is the second largest provider of non-hazardous solid waste collection, transfer, recycling, disposal and energy services in the United States, as measured by revenue. We manage and evaluate our operations through two field groups, Group 1 and Group 2, which we have identified as our reportable segments. The unaudited consolidated financial statements include the accounts of Republic and its wholly owned and majority owned subsidiaries in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). We account for investments in entities in which we do not have a controlling financial interest under either the equity method or cost method of accounting, as appropriate. All material intercompany accounts and transactions have been eliminated in consolidation. We have prepared these unaudited consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information related to our organization, significant accounting policies and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP has been condensed or omitted. In the opinion of management, these financial statements include all adjustments that, unless otherwise disclosed, are of a normal recurring nature and necessary for a fair presentation of the financial position, results of operations and cash flows for the periods presented. Operating results for interim periods are not necessarily indicative of the results you can expect for a full year. You should read these financial statements in conjunction with our audited consolidated financial statements and notes thereto appearing in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 . For comparative purposes, certain prior year amounts have been reclassified to conform to the current year presentation. All dollar amounts in tabular presentations are in millions, except per share amounts and unless otherwise noted. Management’s Estimates and Assumptions In preparing our financial statements, we make numerous estimates and assumptions that affect the amounts reported in these financial statements and accompanying notes. We must make these estimates and assumptions because certain information we use is dependent on future events, cannot be calculated with a high degree of precision from data available or simply cannot be readily calculated based on generally accepted methodologies. In preparing our financial statements, the more critical and subjective areas that deal with the greatest amount of uncertainty relate to our accounting for our long-lived assets, including recoverability, development costs, and final capping, closure and post-closure costs; our valuation allowances for accounts receivable and deferred tax assets; our liabilities for potential litigation, claims and assessments; our liabilities for environmental remediation, multiemployer pension funds, employee benefit plans, deferred taxes, uncertain tax positions, and insurance reserves; and our estimates of the fair values of assets acquired and liabilities assumed in any acquisition. Each of these items is discussed in more detail in our description of our significant accounting policies in Note 2, Summary of Significant Accounting Policies , of the Notes to Consolidated Financial Statements in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 . Our actual results may differ significantly from our estimates. New Accounting Pronouncements Accounting Standards Adopted During 2018, we adopted the following accounting standard updates ("ASUs") as issued by the Financial Accounting Standard Board ("FASB"): ASU Effective Date ASU 2014-09 Revenue from Contracts with Customers (Topic 606) and Other Assets and Deferred Costs-Contracts with Customers (Subtopic 340-40) January 1, 2018 ASU 2016-15 Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments January 1, 2018 ASU 2016-18 Statement of Cash Flows (Topic 230) - Restricted Cash January 1, 2018 ASU 2017-01 Business Combinations (Topic 805) - Clarifying the Definition of Business January 1, 2018 ASU 2017-07 Compensation - Retirement Benefits (Topic 715) - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost January 1, 2018 ASU 2017-09 Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting January 1, 2018 Revenue Recognition Effective January 1, 2018, we adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606) and Other Assets and Deferred Costs-Contracts with Customers (Subtopic 340-40) ("ASU 2014-09" or the "new revenue recognition standard") using the modified retrospective approach. We recognized the cumulative effect of adopting the new revenue recognition standard as an adjustment to the beginning balance of Retained Earnings as of the date of adoption. The comparative periods have not been restated and continue to be reported under the accounting standards in effect for those periods. The timing and pattern of revenue recognition has not significantly changed under the new revenue recognition standard, nor has there been a material change to our operating or net income. Under ASU 2014-09, we record revenue when control is transferred to the customer, generally at the time we provide a service. While the timing and pattern of revenue recognition remains unchanged, we identified certain consideration payable to our customers that is now recorded as a reduction of revenue in accordance with the new revenue recognition standard. These costs were historically recorded as a component of cost of operations and include: • payments issued to our municipal customers in accordance with our residential collection contracts, • payments issued to our municipal customers in accordance with certain landfill operating agreements, and • commodity rebates in our collection and recycling lines of business. Historically, we also recognized certain upfront payments to acquire customer contracts as other assets in our consolidated balance sheet and amortized the asset as a component of depreciation, amortization and depletion over the respective contract life. In accordance with the new revenue recognition standard, we now amortize the asset as a reduction of revenue. The timing and pattern of recognizing these payments to our customers have not significantly changed under the new revenue recognition standard. In addition, we historically recognized sales commissions as a component of selling, general and administrative expenses as they were incurred. In accordance with the new revenue recognition standard, we identified certain sales commissions that represent an incremental cost of the contract and should be capitalized and amortized to selling, general and administrative expense over the average life of the customer relationship. The cumulative effect of the changes made to our consolidated balance sheet for the adoption of ASU 2014-09 were as follows: Balance at December 31, 2017 Adjustments due to our adoption of ASU 2014-09 Balance at January 1, 2018 Balance Sheet Assets Other assets $ 335.2 $ 43.8 $ 379.0 Liabilities Deferred income taxes and other long-term tax liabilities, net $ 796.4 $ 10.4 $ 806.8 Equity Retained earnings $ 4,152.5 $ 33.4 $ 4,185.9 The impact of our adoption of the new revenue recognition standard on our consolidated income statement for the three and six months ended June 30, 2018 was as follows: For the three months ended June 30, 2018 For the six months ended June 30, 2018 As Reported Effect of Change As Computed Excluding the Adoption of ASU 2014-09 As Reported Effect of Change As Computed Excluding the Adoption of ASU 2014-09 Income Statement Revenue $ 2,517.8 $ 82.9 $ 2,600.7 $ 4,945.2 $ 169.6 $ 5,114.8 Expenses: Cost of operations $ 1,577.2 $ 81.5 $ 1,658.7 $ 3,047.0 $ 166.8 $ 3,213.8 Depreciation, amortization and depletion $ 255.5 $ 1.4 $ 256.9 $ 518.6 $ 2.8 $ 521.4 Selling, general and administrative $ 252.9 $ (0.1 ) $ 252.8 $ 514.0 $ 0.4 $ 514.4 Operating income $ 408.2 $ 0.1 $ 408.3 $ 812.4 $ (0.4 ) $ 812.0 Statement of Cash flows Effective January 1, 2018 we adopted ASU 2016-15, Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments ("ASU 2016-15") using a retrospective approach to each period presented. In accordance with the standard, we recognize contingent consideration and holdbacks paid within three months of an acquisition's consummation date as cash outflows from investing activities in the statement of cash flows. Payments made thereafter are recognized as cash outflows from financing activities in the statement of cash flows. As the requirements of the standard do not significantly differ from our previous accounting policy, our adoption of this guidance did not have a material impact on our consolidated financial statements. Effective January 1, 2018 we adopted ASU 2016-18, Statement of Cash Flows (Topic 230) - Restricted Cash ("ASU 2016-18") using a retrospective approach to each period presented. As a result of our adoption of the standard, restricted cash and restricted cash equivalents are included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. Consequently, we reclassified the $3.0 million change in restricted cash and restricted cash equivalents from cash used in investing activities for the six months ended June 30, 2017 . Beginning-of-period and end-of-period cash, cash equivalents, restricted cash and restricted cash equivalents as presented in the statement of cash flows is reconciled as follows: June 30, 2018 December 31, 2017 June 30, 2017 December 31, 2016 Cash and cash equivalents $ 61.3 $ 83.3 $ 36.0 $ 67.8 Restricted cash and marketable securities 116.2 141.1 93.3 90.5 Less: restricted marketable securities (44.8 ) (45.3 ) (45.1 ) (45.3 ) Cash, cash equivalents, restricted cash and restricted cash equivalents $ 132.7 $ 179.1 $ 84.2 $ 113.0 Business Combinations Effective January 1, 2018 we adopted ASU 2017-01, Business Combinations (Topic 805) - Clarifying the Definition of Business ("ASU 2017-01"), which assists entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. ASU 2017-01 provides a screen that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. If the screen is not met, the entity then evaluates whether the set meets the requirement that a business include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs. The guidance prescribed by ASU 2017-01 will be applied prospectively to relevant transactions on or after the adoption date and did not have a material impact on the acquisitions accounted for as a business combination during the six months ended June 30, 2018 . Retirement Benefits Effective January 1, 2018 we adopted ASU 2017-07, Compensation - Retirement Benefits (Topic 715) - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost ("ASU 2017-07") using a retrospective approach to each period presented. The standard requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. As our pension plan is frozen, we do not have service costs that qualify for the treatment prescribed by ASU 2017-07. Subsequent to the adoption of ASU 2017-07, net benefit costs (income) are reported in other income. Our adoption of ASU 2017-07 did not have a material impact on our consolidated financial statements for the six months ended June 30, 2018 and 2017 . Stock Compensation Effective January 1, 2018, we adopted ASU 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting ("ASU 2017-09"), which provides clarification on when modification accounting should be used for changes to the terms or conditions of a share-based payment award. ASU 2017-09 does not change the accounting for modifications but clarifies that modification accounting guidance should only be applied if there is a change to the value, vesting conditions, or award classification and would not be required if the changes are considered non-substantive. The adoption of ASU 2017-09 did not have a material impact on our consolidated financial statements for the six months ended June 30, 2018 . Accounting Standards Issued but not yet Adopted Leases In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) ("ASU 2016-02"), which increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. ASU 2016-02 requires lessees to recognize lease assets and liabilities for most leases classified as operating leases under previous U.S. GAAP. The standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. As such, Republic will adopt the standard beginning January 1, 2019. As we progress to adopt the standard, we continually monitor clarifying interpretations. In January 2018, the FASB issued Proposed Accounting Standards Update, Leases (Topic 842) : Targeted Improvements , which proposed amending the guidance to add a method of adoption whereby the issuer may elect to recognize a cumulative-effect adjustment at the beginning of the period of adoption. We currently plan to adopt the standard under this proposed method in the event it is approved by the FASB. The comment deadline for the Exposure Draft was February 5, 2018, and a final decision is pending. Under ASU 2016-02, we will recognize a right-of-use asset and a right-of-use liability for leases classified as operating leases in our consolidated balance sheet. We continue to assess the overall impact to our consolidated financial statements, however, we currently plan to apply the package of practical expedients to leases that commenced before the effective date whereby we will elect to not reassess the following: (i) whether any expired or existing contracts contain leases; (ii) the lease classification for any expired or existing leases; and (iii) initial direct costs for any existing leases. We are assessing the disclosure requirements under ASU 2016-02, and we anticipate disclosing additional information, as necessary, to comply with the standard. To assist in quantifying the impact on our consolidated financial statements and supplementing our existing disclosures, we are in the process of implementing a software solution to manage and account for our leases. Derivatives and Hedging In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities ("ASU 2017-12"). ASU 2017-12 intends to address concerns through changes to hedge accounting guidance which will accomplish the following: a) Expand hedge accounting for nonfinancial and financial risk components and amend measurement methodologies to more closely align hedge accounting with a company's risk management activities; b) Decrease the complexity of preparing and understanding hedge results through eliminating the separate measurement and reporting of hedge ineffectiveness; c) Enhance transparency, comparability and understandability of hedge results through enhanced disclosures and changing the presentation of hedge results to align the effects of the hedging instrument and the hedged item; and d) Reduce the cost and complexity of applying hedge accounting by simplifying the manner in which assessments of hedge effectiveness may be performed. ASU 2017-12 is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted in any interim period following the issuance date. We are currently assessing the effect this guidance may have on our consolidated financial statements. Reclassifications of Certain Tax Effects from Accumulated Other Comprehensive Income In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income ("ASU 2018-02"). ASU 2018-02 allows the reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act (the "Tax Act"). Consequently, the amendments eliminate the stranded tax effects resulting from the Tax Act and will improve the usefulness of information reported to financial statement users. However, because the amendments only relate to the reclassification of the income tax effects of the Tax Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected. ASU 2018-02 is effective for all entities for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. We are currently assessing the effect this guidance may have on our consolidated financial statements. Income Taxes In March 2018, the FASB issued ASU 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 (SEC Update) which provides guidance on accounting for the tax effects of the Tax Act. See Note 8, Income Taxes for discussion on our adoption plans. Improvements to Nonemployee Share-Based Payment Accounting In June 2018, the FASB issued ASU 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting ("ASU 2018-07"). ASU 2018-07 simplifies several aspects of the accounting for nonemployee share-based payment transactions resulting from expanding the scope of Topic 718, Compensation—Stock Compensation, to include share-based payment transactions for acquiring goods and services from nonemployees. ASU 2018-07 is effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. We are currently assessing the effect this guidance may have on our consolidated financial statements.

Business Acquisitions and Restructuring Charges	BUSINESS ACQUISITIONS AND RESTRUCTURING CHARGES Acquisitions We acquired various waste businesses during the six months ended June 30, 2018 and 2017 . The purchase price for these acquisitions and the allocations of the purchase price follow: 2018 2017 Purchase price: Cash used in acquisitions, net of cash acquired $ 63.6 $ 81.7 Holdbacks 8.4 3.8 Fair value of operations surrendered — 2.1 Total 72.0 87.6 Allocated as follows: Accounts receivable 1.5 1.7 Landfill airspace 22.2 — Property and equipment 12.1 30.7 Other assets 0.1 — Inventory 0.2 0.4 Accounts payable (0.3 ) — Environmental remediation liabilities — (0.1 ) Closure and post-closure liabilities (1.7 ) — Other liabilities (3.9 ) (1.8 ) Fair value of tangible assets acquired and liabilities assumed 30.2 30.9 Excess purchase price to be allocated $ 41.8 $ 56.7 Excess purchase price allocated as follows: Other intangible assets $ 10.5 $ 8.6 Goodwill 31.3 48.1 Total allocated $ 41.8 $ 56.7 The purchase price allocations are preliminary and are based on information existing at the acquisition dates. Accordingly, the purchase price allocations are subject to change. Substantially all of the goodwill and intangible assets recorded for these acquisitions are deductible for tax purposes. These acquisitions are not material to the Company's results of operations, individually or in the aggregate. As a result, no pro forma financial information is provided. Restructuring Charges In January 2016, we realigned our field support functions by combining our three regions into two field groups, consolidating our areas and streamlining select operational support roles at our Phoenix headquarters. Additionally, in the second quarter of 2016, we began the redesign of our back-office functions as well as the consolidation of over 100 customer service locations into three Customer Resource Centers. During the three and six months ended June 30, 2017 , we incurred restructuring charges of $ 4.1 million and $8.5 million , respectively, that consisted of severance and other employee termination benefits, transition costs, relocation benefits, and the closure of offices with lease agreements with non-cancelable terms. The savings realized from these restructuring efforts have been reinvested in our customer-focused programs and initiatives. In January 2018, we eliminated certain positions following the consolidation of select back-office functions, including but not limited to the integration of our National Accounts support functions into our existing corporate support functions. These changes include a reduction in administrative staffing and closing of certain office locations. During the three and six months ended June 30, 2018 , we incurred restructuring charges of $3.8 million and $13.3 million , respectively, that primarily consisted of severance and other employee termination benefits and the closure of offices with lease agreements with non-cancelable terms. We paid $4.2 million and $12.6 million during the three and six months ended June 30, 2018 , respectively, related to these restructuring efforts. We expect to incur additional charges of between approximately $5 million to $10 million during the remainder of 2018 , primarily related to employee severance costs, lease exit and contract termination costs and the relocation of certain employees. Substantially all of these restructuring charges will be recorded in our corporate segment.

While the ultimate amount of claims incurred depends on future developments, we believe the recorded reserves are adequate to cover the future payment of claims; however, it is possible that these recorded reserves may not be adequate to cover the future payment of claims. Adjustments, if any, to estimates recorded resulting from ultimate claim payments will be reflected in our consolidated statements of income in the periods in which such adjustments are known.

Environmental Remediation Obligations [Abstract]
Landfill and Environmental Costs	LANDFILL AND ENVIRONMENTAL COSTS As of June 30, 2018 , we owned or operated 194 active landfills with total available disposal capacity of approximately 5.1 billion in-place cubic yards. We also have post-closure responsibility for 126 closed landfills. Accrued Landfill and Environmental Costs A summary of accrued landfill and environmental liabilities as of June 30, 2018 and December 31, 2017 follows: 2018 2017 Landfill final capping, closure and post-closure liabilities $ 1,282.3 $ 1,257.7 Environmental remediation liabilities 555.4 564.0 Total accrued landfill and environmental costs 1,837.7 1,821.7 Less: current portion (150.5 ) (135.2 ) Long-term portion $ 1,687.2 $ 1,686.5 Final Capping, Closure and Post-Closure Costs The following table summarizes the activity in our asset retirement obligation liabilities, which include liabilities for landfill final capping, closure and post-closure, for the six months ended June 30, 2018 and 2017 : 2018 2017 Asset retirement obligation liabilities, beginning of year $ 1,257.7 $ 1,224.6 Non-cash additions 21.8 22.3 Acquisitions, net of divestitures and other adjustments 1.9 (25.1 ) Asset retirement obligation adjustments (17.6 ) 0.1 Payments (22.1 ) (28.3 ) Accretion expense 40.6 39.9 Asset retirement obligation liabilities, end of period 1,282.3 1,233.5 Less: current portion (81.0 ) (71.7 ) Long-term portion $ 1,201.3 $ 1,161.8 We review annually, in the fourth quarter, and update as necessary, our estimates of asset retirement obligation liabilities. However, if there are significant changes in the facts and circumstances related to a site during the year, we will update our assumptions prospectively in the period that we know all the relevant facts and circumstances and make adjustments as appropriate. During the six months ended June 30, 2017 , we transferred our ownership of the landfill gas collection and control system and the remaining post-closure and environmental liabilities of $24.8 million and $6.3 million , respectively, associated with one of our divested landfills. The fair value of assets that are legally restricted for purposes of settling final capping, closure and post-closure liabilities was $29.0 million and $28.6 million as of June 30, 2018 and December 31, 2017 , respectively, and is included in restricted cash and marketable securities in our consolidated balance sheets. Landfill Operating Expenses In the normal course of business, we incur various operating costs associated with environmental compliance. These costs include, among other things, leachate treatment and disposal, methane gas and groundwater monitoring, systems maintenance, interim cap maintenance, costs associated with the application of daily cover materials, and the legal and administrative costs of ongoing environmental compliance. These costs are expensed as cost of operations in the periods in which they are incurred. Environmental Remediation Liabilities We accrue for remediation costs when they become probable and can be reasonably estimated. There can sometimes be a range of reasonable estimates of the costs associated with remediation of a site. In these cases, we use the amount within the range that constitutes our best estimate. If no amount within the range appears to be a better estimate than any other, we use the amount that is at the low end of the range. It is reasonably possible that we will need to adjust the liabilities recorded for remediation to reflect the effects of new or additional information, to the extent such information impacts the costs, timing or duration of the required actions. If we used the reasonably possible high ends of our ranges, our aggregate potential remediation liability as of June 30, 2018 would be approximately $466 million higher than the amount recorded. Future changes in our estimates of the cost, timing or duration of the required actions could have a material adverse effect on our consolidated financial position, results of operations and cash flows. The following table summarizes the activity in our environmental remediation liabilities for the six months ended June 30, 2018 and 2017 : 2018 2017 Environmental remediation liabilities, beginning of year $ 564.0 $ 602.9 Net additions charged to expense 2.5 — Payments (21.2 ) (23.8 ) Accretion expense (non-cash interest expense) 10.1 10.6 Acquisitions, net of divestitures and other adjustments — (6.1 ) Environmental remediation liabilities, end of period 555.4 583.6 Less: current portion (69.5 ) (74.3 ) Long-term portion $ 485.9 $ 509.3 Bridgeton Landfill. During the six months ended June 30, 2018 , we paid $7.7 million related to management and monitoring of the remediation area for our closed Bridgeton Landfill in Missouri. We continue to work with state and federal regulatory agencies on our remediation efforts. From time to time, this may require us to modify our future operating timeline and procedures, which could result in changes to our expected remediation liability. As of June 30, 2018 , the remediation liability recorded for this site was $169.6 million , of which approximately $13 million is expected to be paid during the remainder of 2018. We believe the remaining reasonably possible high end of our range would be approximately $177 million higher than the amount recorded as of June 30, 2018 . West Lake Landfill Superfund Site . Our subsidiary Bridgeton Landfill, LLC is one of several currently designated Potentially Responsible Parties for the West Lake Landfill Superfund site ("West Lake") in Missouri. On February 6, 2018, the U.S. Environmental Protection Agency ("EPA") issued a Proposed Record of Decision Amendment for West Lake that includes a total cost estimate of $236 million over a five -year remediation timeline. A 75 day public comment period followed the announcement. At this time we are neither able to predict the final remedy that EPA may eventually select in its Record of Decision ("ROD") following the comment period, nor estimate how much of the future response costs of the site our subsidiary may agree or be required to pay. During any subsequent administrative proceedings or litigation, our subsidiary will vigorously contest liability for the costs of remediating radiologically-impacted materials generated on behalf of the federal government during the Manhattan Project and delivered to the site by an Atomic Energy Commission licensee and its subcontractor. Currently, we believe we are adequately reserved for the ROD that was issued in 2008. However, issuance of the final ROD and subsequent events related to remedy divisibility or allocation may require us to modify our expected remediation liability.

The Credit Facility is unsecured and matures in June 2023. We may request two one -year extensions of the maturity date but none of the lenders are committed to participate in such extension. The Credit Facility also includes a feature that allows us to increase availability, at our option, by an aggregate amount of up to $1.0 billion through increased commitments from existing lenders or the addition of new lenders. At our option, borrowings under the Credit Facility bear interest at a Base Rate, or a Eurodollar Rate, plus an applicable margin based on our Debt Ratings (all as defined in the Credit Facility agreement). The Credit Facility is subject to facility fees based on applicable rates defined in the Credit Facility agreement and the aggregate commitment, regardless of usage. Availability under our Credit Facility totaled $1,745.3 million as of June 30, 2018 and under the Replaced Credit Facilities totaled $1,639.1 million as of December 31, 2017 . The Credit Facility can be used for working capital, capital expenditures, acquisitions, letters of credit and other general corporate purposes. The Credit Facility agreement requires us to comply with financial and other covenants. We may pay dividends and repurchase common stock if we are in compliance with these covenants. As of June 30, 2018 , we had $80.0 million of borrowings under our Credit Facility and $130.0 million of borrowings under the Replaced Credit Facilities as of December 31, 2017 . We had $406.5 million of letters of credit outstanding under our Credit Facility as of June 30, 2018 and $462.7 million of letters of credit outstanding under our Replaced Credit Facilities as of December 31, 2017 . Our Uncommitted Credit Facility bears interest at LIBOR, plus an applicable margin and is subject to facility fees defined in the agreement, regardless of usage. We can use borrowings under the Uncommitted Credit Facility for working capital and other general corporate purposes. The agreement governing our Uncommitted Credit Facility requires us to comply with certain covenants. The Uncommitted Credit Facility may be terminated by either party at any time. We had $44.7 million of borrowings and no borrowings outstanding under our Uncommitted Credit Facility as of June 30, 2018 and December 31, 2017 , respectively. Senior Notes and Debentures In May 2018, we issued $800.0 million of 3.950% senior notes due 2028 (the " 3.950% Notes"). We used the net proceeds from the 3.950% Notes to repay $700.0 million of 3.800% senior notes that matured in May 2018, and any remaining proceeds were used for general corporate purposes. In connection with this offering we terminated interest rate lock agreements with a notional value of $600.0 million resulting in net proceeds of $31.1 million . There was no ineffectiveness recognized in the termination of these cash flow hedges. Our senior notes and debentures are general unsecured obligations. Interest is payable semi-annually. The senior notes have a make-whole provision that is exercisable at any time three months prior to their respective maturity dates at a stated redemption price. Tax-Exempt Financings As of June 30, 2018 and December 31, 2017 , we had $1,036.6 million and $1,036.0 million , respectively, of fixed and variable rate tax-exempt financings outstanding with maturities ranging from 2019 to 2044 . Approximately 100% of our tax-exempt financings are remarketed quarterly by remarketing agents to effectively maintain a variable yield. The holders of the bonds can put them back to the remarketing agents at the end of each interest period. To date, the remarketing agents have been able to remarket our variable rate unsecured tax-exempt bonds. These bonds have been classified as long-term because of our ability and intent to refinance them using availability under our Credit Facility, if necessary. Capital Leases We had capital lease liabilities of $106.4 million and $108.4 million as of June 30, 2018 and December 31, 2017 , respectively, with maturities ranging from 2018 to 2046 . Interest Rate Swap and Lock Agreements Our ability to obtain financing through the capital markets is a key component of our financial strategy. Historically, we have managed risk associated with executing this strategy, particularly as it relates to fluctuations in interest rates, by using a combination of fixed and floating rate debt. From time to time, we have also entered into interest rate swap and lock agreements to manage risk associated with interest rates, either to effectively convert specific fixed rate debt to a floating rate (fair value hedges), or to lock interest rates in anticipation of future debt issuances (cash flow hedges). Fair Value Hedges During the second half of 2013, we entered into various interest rate swap agreements relative to our 4.750% fixed rate senior notes due in May 2023. The goal was to reduce overall borrowing costs and rebalance our debt portfolio's ratio of fixed to floating interest rates. As of June 30, 2018 , these swap agreements had a total notional value of $300.0 million and mature in May 2023, which is identical to the maturity of the hedged senior notes. We pay interest at floating rates based on changes in LIBOR and receive interest at a fixed rate of 4.750% . These transactions were designated as fair value hedges because the swaps hedge against the changes in fair value of the fixed rate senior notes resulting from changes in interest rates. As of June 30, 2018 and December 31, 2017 , the interest rate swap agreements are reflected at their fair value of $(1.5) million and $8.0 million , respectively, and are included in other long-term liabilities and other assets. To the extent they are effective, these interest rate swap agreements are included as an adjustment to long-term debt in our consolidated balance sheets. We recognized net interest income of $0.5 million and $1.4 million during the three and six months ended June 30, 2018 , respectively, and $1.3 million and $2.6 million during the three and six months ended June 30, 2017 , respectively, related to net swap settlements for these interest rate swap agreements, which is included as an offset to interest expense in our unaudited consolidated statements of income. For the three months ended June 30, 2018 and 2017 , we recognized gains (losses) of $2.5 million and $(1.4) million , respectively, on the change in fair value of the hedged senior notes attributable to changes in the benchmark interest rate, and (losses) gains of $(2.7) million and $1.6 million , respectively, on the related interest rate swaps. For the six months ended June 30, 2018 and 2017 , we recognized gains of $9.2 million and $ 0.2 million , respectively, on the change in fair value of the hedged senior notes attributable to changes in the benchmark interest rate, and (losses) gains of $(9.5) million and $ 0.2 million , respectively, on the related interest rate swaps. The net amount of these fair value changes represents hedge ineffectiveness, which is recorded directly in earnings as other income, net. Cash Flow Hedges Our interest rate lock agreements had an aggregate notional amount of $450.0 million as of June 30, 2018 with fixed interest rates ranging from 1.900% to 2.950% . Upon the expected issuance of senior notes, we will terminate the interest rate locks and settle with our counterparties. These transactions were accounted for as cash flow hedges. The fair value of our interest rate locks as of June 30, 2018 was determined using standard valuation models with assumptions about interest rates being based on those observed in underlying markets (Level 2 in the fair value hierarchy). The aggregate fair values of the outstanding interest rate locks as of June 30, 2018 and December 31, 2017 were $23.9 million and $19.1 million , respectively, and were recorded in other long term assets in our consolidated balance sheet. No amounts were recognized in other income, net in our consolidated statements of income for the ineffective portion of the changes of fair values during the three and six months ended June 30, 2018 and 2017 , respectively. Total loss recognized in other comprehensive income, net of tax, was $(12.2) million and $(3.4) million for the three months ended June 30, 2018 and 2017 . As of June 30, 2018 and December 31, 2017 , the effective portion of our previously terminated interest rate locks, recorded as a component of accumulated other comprehensive income, net of tax , was income of $(11.6) million and loss of $11.8 million , respectively. The effective portion of the interest rate locks is amortized as an adjustment to interest expense over the life of the issued debt using the effective interest method. We expect to amortize approximately $(0.6) million of net interest expense (income) over the next twelve months as a yield adjustment of our senior notes. The effective portion of the interest rate locks amortized as a net increase to interest expense was $0.3 million and $0.7 million during the three months ended June 30, 2018 and 2017 , respectively, and $0.8 million and $1.3 million during the six months ended June 30, 2018 and 2017 , respectively.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES Our effective tax rate, exclusive of noncontrolling interests, for the three and six months ended June 30, 2018 was 24.7% and 24.1% , respectively. Our effective tax rate, exclusive of noncontrolling interests, for the three and six months ended June 30, 2017 , was 39.1% and 37.9% , respectively. Our effective tax rate, exclusive of noncontrolling interests, for the three and six months ended June 30, 2018 was favorably affected by the Tax Act and resolution of certain tax matters as compared to the same periods in 2017 . Cash paid for income taxes (net of refunds) was $30.0 million and $170.0 million for the six months ended June 30, 2018 and 2017 , respectively. The Tax Act was enacted on December 22, 2017. The Tax Act reduces the U.S. federal corporate tax rate from 35% to 21%, limits deductions for, among other things, interest expense, executive compensation and meals and entertainment, while enhancing deductions for equipment and other fixed assets. The Tax Act also requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred and creates new taxes on certain foreign sourced earnings. The SEC staff issued Staff Accounting Bulletin No. 118 ("SAB 118"), which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides up to a one year measurement period from the Tax Acts's enactment date for companies to complete their accounting under ASC 740. In accordance with SAB 118, for the year ended December 31, 2017 , we recorded provisional amounts based on our estimates of the Tax Act's effect to our deferred taxes, uncertain tax positions and the one-time transition tax. As of June 30, 2018 , we have not finalized our accounting nor have we changed our previous estimates of the tax effects of the enactment of the Tax Act. We anticipate that the completion of our 2017 income tax returns, future guidance and additional information and interpretations with respect to the Tax Act will cause us to further adjust the provisional amounts recorded as of December 31, 2017. In accordance with SAB 118, we will record such adjustments in the period that relevant guidance and/or additional information becomes available and our analysis is completed. We are subject to income tax in the United States and Puerto Rico, as well as in multiple state jurisdictions. Our compliance with income tax rules and regulations is periodically audited by taxing authorities. These authorities may challenge the positions taken in our tax filings. We are currently under examination or administrative review by state and local taxing authorities for various tax years. We recognize interest and penalties as incurred within the provision for income taxes in the consolidated statements of income. As of June 30, 2018 , we accrued a liability for penalties of $0.5 million and a liability for interest (including interest on penalties) of $11.3 million related to our uncertain tax positions. We believe that our recorded liabilities for uncertain tax positions are adequate. However, a significant assessment against us in excess of the liabilities recorded could have a material adverse effect on our consolidated financial position, results of operations and cash flows. During the next twelve months, it is reasonably possible that the amount of unrecognized tax benefits will increase or decrease. Gross unrecognized benefits we expect to settle in the next twelve months are in the range of zero to $10 million . We have deferred tax assets related to state net operating loss carryforwards. We provide a partial valuation allowance due to uncertainty surrounding the future utilization of these carryforwards in the taxing jurisdictions where the loss carryforwards exist. When determining the need for a valuation allowance, we consider all positive and negative evidence, including recent financial results, scheduled reversals of deferred tax liabilities, projected future taxable income and tax planning strategies. The weight given to the positive and negative evidence is commensurate with the extent such evidence can be objectively verified. As a result of the recent changes in U.S. tax law, as well as our ongoing efforts to streamline and maximize the efficiency of our tax footprint, we could further adjust our valuation allowance in a future period if there is sufficient evidence to support a conclusion that it is more certain than not that certain of the state net operating loss carryforwards, on which we currently provide a valuation allowance, would be realized. The realization of our deferred tax asset for state loss carryforwards ultimately depends upon the existence of sufficient taxable income in the appropriate state taxing jurisdictions in future periods. We continue to regularly monitor both positive and negative evidence in determining the ongoing need for a valuation allowance. As of June 30, 2018 , the valuation allowance associated with our state loss carryforwards was approximately $72 million .

Additionally, as of June 30, 2018 and 2017 , $10.3 million and $6.6 million of share repurchases were unpaid and included within other accrued liabilities, respectively. In October 2017, our board of directors added $2.0 billion to our existing share repurchase authorization that now extends through December 31, 2020. Before this, $98.4 million remained under a prior authorization. Share repurchases under the program may be made through open market purchases or privately negotiated transactions in accordance with applicable federal securities laws. While the board of directors has approved the share purchase program, the timing of any purchases, the prices and the number of shares of common stock to be purchased will be determined by our management, and will depend upon market conditions and other factors. The program may be extended, suspended or discontinued at any time. As of June 30, 2018 , the remaining authorized purchase capacity under our October 2017 repurchase program was $1.4 billion . Dividends In April 2018, our board of directors approved a quarterly dividend of $0.345 per share. Cash dividends declared were $225.7 million for the six months ended June 30, 2018 . As of June 30, 2018 , we recorded a quarterly dividend payable of $112.3 million to shareholders of record at the close of business on July 2, 2018. Earnings per Share Basic earnings per share is computed by dividing net income attributable to Republic Services, Inc. by the weighted average number of common shares (including vested but unissued RSUs) outstanding during the period. Diluted earnings per share is based on the combined weighted average number of common shares and common share equivalents outstanding, which include, where appropriate, the assumed exercise of employee stock options, unvested RSUs and unvested PSUs at the expected attainment levels. We use the treasury stock method in computing diluted earnings per share. Earnings per share for the three and six months ended June 30, 2018 and 2017 are calculated as follows (in thousands, except per share amounts): Three Months Ended June 30, Six Months Ended June 30, 2018 2017 2018 2017 Basic earnings per share: Net income attributable to Republic Services, Inc. $ 234,900 $ 202,900 $ 472,600 $ 390,700 Weighted average common shares outstanding 327,365 338,057 329,003 338,962 Basic earnings per share $ 0.72 $ 0.60 $ 1.44 $ 1.15 Diluted earnings per share: Net income attributable to Republic Services, Inc. $ 234,900 $ 202,900 $ 472,600 $ 390,700 Weighted average common shares outstanding 327,365 338,057 329,003 338,962 Effect of dilutive securities: Options to purchase common stock 810 1,269 858 1,340 Unvested RSU awards 202 333 231 343 Unvested PSU awards 453 313 421 282 Weighted average common and common equivalent shares outstanding 328,830 339,972 330,513 340,927 Diluted earnings per share $ 0.71 $ 0.60 $ 1.43 $ 1.15 There were no antidilutive securities during the three and six months ended June 30, 2018 and 2017 .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments	FINANCIAL INSTRUMENTS Fuel Hedges We have entered into multiple swap agreements designated as cash flow hedges to mitigate some of our exposure related to changes in diesel fuel prices. These swaps qualified for, and were designated as, effective hedges of changes in the prices of forecasted diesel fuel purchases (fuel hedges). The following table summarizes our outstanding fuel hedges as of June 30, 2018 : Year Gallons Hedged Weighted Average Contract Price per Gallon 2018 3,750,000 $2.59 If the national U.S. on-highway average price for a gallon of diesel fuel as published by the Department of Energy exceeds the contract price per gallon, we receive the difference between the average price and the contract price (multiplied by the notional gallons) from the counterparty. If the average price is less than the contract price per gallon, we pay the difference to the counterparty. The fair values of our fuel hedges are determined using standard option valuation models with assumptions about commodity prices based on those observed in underlying markets (Level 2 in the fair value hierarchy). The aggregate fair values of our outstanding fuel hedges as of June 30, 2018 were current assets of $2.6 million , which have been recorded in other current assets in our consolidated balance sheets. As of December 31, 2017 , the aggregate fair values of our outstanding fuel hedges were current assets of $3.0 million , which are included in other current assets in our consolidated balance sheets. No amounts were recognized in other income, net in our unaudited consolidated statements of income for the ineffectiveness portion of the changes in fair values for each of the three or six months ended June 30, 2018 and 2017 . For the three and six months ended June 30, 2018 , a gain of $0.1 million was recognized in other comprehensive income , net of tax, for fuel hedges (the effective portion), and no gain (loss) was recognized in other comprehensive income, net of tax, for fuel hedges (the effective portion) for the three and six months ended June 30, 2017 . We classify cash inflows and outflows from our fuel hedges within operating activities in the unaudited consolidated statements of cash flows. Recyclable Commodity Hedges Revenue from the sale of recycled commodities is primarily from sales of old corrugated containers ("OCC") and old newsprint. From time to time we use derivative instruments such as swaps and costless collars designated as cash flow hedges to manage our exposure to changes in prices of these commodities. During 2017 , we entered into multiple agreements related to the forecasted OCC sales. The agreements qualified for, and were designated as, effective hedges of changes in the prices of certain forecasted recyclable commodity sales (commodity hedges). We entered into costless collar agreements on forecasted sales of OCC. The agreements involve combining a purchased put option giving us the right to sell OCC at an established floor strike price with a written call option obligating us to deliver OCC at an established cap strike price. The puts and calls have the same settlement dates, are net settled in cash on such dates and have the same terms to expiration. The contemporaneous combination of options resulted in no net premium for us and represents costless collars. Under these agreements, we will neither make or receive payments as long as the settlement price is between the floor price and cap price; however, if the settlement price is above the cap, we will pay the counterparty an amount equal to the excess of the settlement price over the cap times the monthly volumes hedged. If the settlement price is below the floor, the counterparty will pay us the deficit of the settlement price below the floor times the monthly volumes hedged. The objective of these agreements is to reduce variability of cash flows for forecasted sales of OCC between two designated strike prices. As of June 30, 2018 , we had outstanding costless collar hedges for OCC totaling 60,000 tons with a weighted average floor strike price of $81.50 per ton and a weighted average cap strike price of $120.00 per ton, all of which will be settled in 2018. Costless collar hedges are recorded in our consolidated balance sheets at fair value. Fair values of costless collars are determined using standard option valuation models with assumptions about commodity prices based upon forward commodity price curves in underlying markets (Level 2 in the fair value hierarchy). The aggregate fair values of the outstanding recyclable commodity hedges as of June 30, 2018 were current assets of $0.8 million , which are included in prepaid expenses and other current assets in our consolidated balance sheets. As of December 31, 2017 , the aggregate fair values of the outstanding recyclable commodity hedges were current liabilities of $0.2 million , which are included in other accrued liabilities in our consolidated balance sheets. No amounts were recognized in other income, net in our unaudited consolidated statements of income for the ineffectiveness portion of the changes in fair values during the three and six months ended June 30, 2018 and 2017 . Total gains (losses) recognized in other comprehensive income for recyclable commodity hedges (the effective portion) was $0.3 million and $0.7 million , net of tax, for the three and six months ended June 30, 2018 , respectively, and $(0.6) million and $(1.2) million , net of tax, for the same periods in 2017 , respectively. Fair Value Measurements In measuring the fair values of assets and liabilities, we use valuation techniques that maximize the use of observable inputs (Level 1) and minimize the use of unobservable inputs (Level 3). We also use market data or assumptions that we believe market participants would use in pricing an asset or liability, including assumptions about risk when appropriate. The carrying value for certain of our financial instruments, including cash, accounts receivable, accounts payable and certain other accrued liabilities, approximates fair value because of their short-term nature. As of June 30, 2018 and December 31, 2017 , our assets and liabilities that are measured at fair value on a recurring basis include the following: Fair Value Measurements Using Carrying Amount Total as of June 30, 2018 Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets: Money market mutual funds $ 42.8 $ 42.8 $ 42.8 $ — $ — Bonds - restricted cash and marketable securities and other assets 53.0 53.0 — 53.0 — Fuel hedges - other current assets 2.6 2.6 — 2.6 — Commodity hedges - other current assets 0.8 0.8 — 0.8 — Interest rate locks - other assets 23.9 23.9 — 23.9 — Total assets $ 123.1 $ 123.1 $ 42.8 $ 80.3 $ — Liabilities: Interest rate swaps - other long-term liabilities $ 1.5 $ 1.5 $ — $ 1.5 $ — Contingent consideration - other long-term liabilities 72.7 72.7 — — 72.7 Total liabilities $ 74.2 $ 74.2 $ — $ 1.5 $ 72.7 Fair Value Measurements Using Carrying Amount Total as of December 31, 2017 Quoted Significant Significant Assets: Money market mutual funds $ 30.3 $ 30.3 $ 30.3 $ — $ — Bonds - restricted cash and marketable securities and other assets 92.1 92.1 — 92.1 — Fuel hedges - other current assets 3.0 3.0 — 3.0 — Interest rate swaps - other assets 8.0 8.0 — 8.0 — Interest rate locks - other assets 19.1 19.1 — 19.1 — Total assets $ 152.5 $ 152.5 $ 30.3 $ 122.2 $ — Liabilities: Commodity hedges - other accrued liabilities $ 0.2 $ 0.2 $ — $ 0.2 $ — Contingent consideration- other long-term liabilities 73.3 73.3 — — 73.3 Total liabilities $ 73.5 $ 73.5 $ — $ 0.2 $ 73.3 Total Debt As of June 30, 2018 and December 31, 2017 , the carrying value of our total debt was $8.3 billion and $8.2 billion , respectively, and the fair value of our total debt was $8.6 billion and $8.8 billion , respectively. The estimated fair value of our fixed rate senior notes and debentures is based on quoted market prices. The fair value of our remaining notes payable, tax-exempt financings and borrowings under our credit facilities approximates the carrying value because the interest rates are variable. The fair value estimates are based on Level 2 inputs of the fair value hierarchy as of June 30, 2018 and December 31, 2017 , respectively. See Note 7, Debt , for further information related to our debt. Contingent Consideration In April 2015, we entered into a waste management contract with Sonoma County, California to operate the county's waste management facilities. As of June 30, 2018 , we recognized $67.6 million of contingent consideration which represents the fair value of amounts payable to Sonoma County based on the achievement of future annual tonnage targets through the expected remaining capacity of the landfill. We estimate the remaining life of the landfill to be approximately 30 years . The potential undiscounted amount of all future contingent payments that we could be required to make under the waste management contract is estimated to be between approximately $82 million and $171 million . The fair value of the contingent consideration was determined using probability assessments of the expected future payments over the remaining useful life of the landfill, and applying a discount rate of 4.0% . The future payments are based on significant inputs that are not observable in the market. Key assumptions include annual volume of tons disposed at the landfill, the price paid per ton and the discount rate that represent the best estimates of management, which are subject to remeasurement at each reporting date. In 2017, we recognized additional contingent consideration associated with the acquisition of a landfill. As of June 30, 2018 , the contingent consideration of $5.1 million represents the fair value of amounts payable to the seller based on annual volume of tons disposed at the landfill. The fair value of the contingent consideration was determined using probability assessments of the expected future payments over the remaining useful life of the landfill, and applying a discount rate of 4.3% . The future payments are based on significant inputs that are not observable in the market. Key assumptions include annual volume of tons disposed at the landfill, which are subject to remeasurement at each reporting date. The contingent consideration liabilities are classified within Level 3 of the fair value hierarchy.

Similar fees were presented as a cost of operations for the three and six months ended June 30, 2017 . (2) In accordance with our adoption of the new revenue recognition standard, rebates paid to customers associated with recycled commodities were presented as a reduction to revenue for the three and six months ended June 30, 2018 . Similar costs were presented as a cost of operations for the three and six months ended June 30, 2017 . Other non-core revenue consists primarily of revenue from National Accounts, which represents the portion of revenue generated from nationwide or regional contracts in markets outside our operating areas where the associated waste handling services are subcontracted to local operators. Consequently, substantially all of this revenue is offset with related subcontract costs, which are recorded in cost of operations. The factors that impact the timing and amount of revenue recognized for each service line may vary based on the nature of the service performed. Generally, we recognize revenue at the time we perform a service. In the event that we bill for services in advance of performance, we recognized deferred revenue for the amount billed and subsequently recognize revenue at the time the service is provided. Depending upon the nature of the contract, we may also generate revenue through the collection of fuel recovery fees and environmental fees which are designed to recover our internal costs of providing services to our customers. See Note 13, Segment Reporting , for additional information regarding revenue by reportable segment. Revenue by Service Line Collection Services Our collection business involves the collection of waste for transport to transfer stations, or directly to landfills or recycling centers. Our solid waste collection services business includes both recurring and temporary customer relationships. Our standard contract duration is three years, although some of our exclusive franchises are for significantly longer periods. The fees received for collection services are based primarily on the market, collection frequency, type of service, type and volume or weight of the waste collected, the distance to the disposal facility and the cost of disposal. In general, small-container and residential collection fees are billed monthly or quarterly in advance. Substantially all of the deferred revenue recognized as of December 31, 2017 was recognized as revenue during the six months ended June 30, 2018 when the service was performed. Our large-container customers are typically billed on a monthly basis based on the nature of the services provided during the period. Revenue recognized under these agreements is variable in nature based on the number of residential homes or businesses serviced during the period, the frequency of collection and the volume of waste collected. In addition, certain of our contracts have annual price escalation clauses that are tied to changes in an underlying base index such as a consumer price index which are unknown at contract inception. Transfer Services Revenue at our transfer stations is primarily generated by charging tipping or disposal fees. The fees received for transfer services are based primarily on the market, type and volume or weight of the waste accepted, the distance to the disposal facility and the cost of disposal. In general, fees are billed and revenue is recognized at the time the service is performed. Revenue recognized under these agreements is variable in nature based on the volume of waste accepted at the transfer station. Landfill Services Revenue at our landfills is primarily generated by charging tipping fees to third parties based on the volume disposed and the nature of the waste. In general, fees are variable in nature and revenue is recognized at the time the waste is disposed at the facility. Energy Services Energy Services revenue is primarily generated through waste managed from vertical and horizontal drilling, hydraulic fracturing, production and clean-up activity, as well as other services including closed loop collection systems and the sale of recovered products. Energy services activity varies across market areas that are tied to the natural resource basins in which the drilling activity occurs and reflects the regulatory environment, pricing and disposal alternatives available in any given market. Revenue recognized under these agreements is variable in nature based on the volume of waste accepted or processed during the period. Sale of Recycled Commodities Our recycling centers generate revenue through the processing and sale of OCC, old newsprint ("ONP"), aluminum, glass and other materials at market prices. In certain instances, we issue recycling rebates to our municipal or large-container customers, which can be based on the price we receive upon the final sale of recycled commodities, a fixed contractual rate or other measures. We also receive rebates when we dispose of recycled commodities at third-party facilities. The fees received are based primarily on the market, type and volume or weight of the materials sold. In general, fees are billed and revenue is recognized at the time title is transferred. Revenue recognized under these agreements is variable in nature based on the volume and type of materials sold. In addition, the amount of revenue recognized is based on commodity prices at the time of sale, which are unknown at contract inception. Revenue Recognition Our service obligations of a long-term nature, e.g., solid waste collection service contracts, are satisfied over time, and we recognize revenue based on the value provided to the customer during the period. The amount billed to the customer is based on variable elements such as the number of residential homes or businesses for which collection services are provided, the volume of waste collected, transported and disposed, and the nature of the waste accepted. We do not disclose the value of unsatisfied performance obligations for these contracts as our right to consideration corresponds directly to the value provided to the customer for services completed to date and all future variable consideration is allocated to wholly unsatisfied performance obligations. Additionally, certain elements of our long-term customer contracts are unknown upon entering into the contract, including the amount that will be billed in accordance with annual price escalation clauses, our fuel recovery fee program and commodity prices. The amount to be billed is often tied to changes in an underlying base index such as a consumer price index or a fuel or commodity index, and revenue can be recognized once the index is established for the period. Deferred Contract Costs We incur certain upfront payments to acquire customer contracts which are recognized as other assets in our consolidated balance sheet, and we amortize the asset over the respective contract life. In addition, we recognize sales commissions that represent an incremental cost of the contract as other assets in our consolidated balance sheet, and we amortize the asset over the average life of the customer relationship. As of June 30, 2018 , we recognized $91.5 million of deferred contract costs and capitalized sales commissions. During the three and six months ended June 30, 2018 , we amortized $2.9 million and $5.5 million , respectively, of capitalized sales commissions to selling, general and administrative expenses and $1.4 million and $2.8 million of other deferred contract costs as a reduction of revenue for the same respective periods.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Legal Proceedings We are subject to extensive and evolving laws and regulations and have implemented safeguards to respond to regulatory requirements. In the normal course of our business, we become involved in legal proceedings. Some may result in fines, penalties or judgments against us, or settlements, which may impact earnings and cash flows for a particular period. Although we cannot predict the ultimate outcome of any legal matter with certainty, we do not believe the outcome of any of our pending legal proceedings will have a material adverse impact on our consolidated financial position, results of operations or cash flows. As used herein, the term legal proceedings refers to litigation and similar claims against us and our subsidiaries, excluding: (1) ordinary course accidents, general commercial liability and workers' compensation claims, which are covered by insurance programs, subject to customary deductibles, and which, together with insured employee health care costs, are discussed in Note 5, Other Liabilities; and (2) environmental remediation liabilities, which are discussed in Note 6, Landfill and Environmental Costs. We accrue for legal proceedings when losses become probable and reasonably estimable. We have recorded an aggregate accrual of approximately $48 million relating to our outstanding legal proceedings as of June 30, 2018 . As of the end of each applicable reporting period, we review each of our legal proceedings and, where it is probable that a liability has been incurred, we accrue for all probable and reasonably estimable losses. Where we can reasonably estimate a range of losses we may incur regarding such a matter, we record an accrual for the amount within the range that constitutes our best estimate. If we can reasonably estimate a range but no amount within the range appears to be a better estimate than any other, we use the amount that is the low end of such range. If we had used the high ends of such ranges, our aggregate potential liability would be approximately $51 million higher than the amount recorded as of June 30, 2018 . Multiemployer Pension Plans We contribute to 25 multiemployer pension plans under collective bargaining agreements covering union-represented employees. These plans generally provide retirement benefits to participants based on their service to contributing employers. We do not administer these plans. Under current law regarding multiemployer pension plans, a plan’s termination, and any termination of an employer’s obligation to make contributions, including our voluntary withdrawal (which we consider from time to time) or the mass withdrawal of all contributing employers from any under-funded multiemployer pension plan (each, a Withdrawal Event) would require us to make payments to the plan for our proportionate share of the plan’s unfunded vested liabilities. During the course of operating our business, we incur Withdrawal Events regarding certain of our multiemployer pension plans. We accrue for such events when losses become probable and reasonably estimable. Restricted Cash and Marketable Securities Our restricted cash and marketable securities include, among other things, restricted cash and marketable securities held for capital expenditures under certain debt facilities, restricted cash and marketable securities pledged to regulatory agencies and governmental entities as financial guarantees of our performance related to our final capping, closure and post-closure obligations at our landfills, and restricted cash and marketable securities related to our insurance obligations. The following table summarizes our restricted cash and marketable securities as of June 30, 2018 and December 31, 2017 : 2018 2017 Financing proceeds $ 12.4 $ 38.6 Capping, closure and post-closure obligations 29.0 28.6 Insurance 74.8 71.4 Other — 2.5 Total restricted cash and marketable securities $ 116.2 $ 141.1 Off-Balance Sheet Arrangements We have no off-balance sheet debt or similar obligations, other than operating leases and financial assurances, which are not classified as debt. We have no transactions or obligations with related parties that are not disclosed, consolidated into or reflected in our reported financial position or results of operations. We have not guaranteed any third-party debt.

Accounting Policies [Abstract]
Management's Estimates and Assumptions	Management’s Estimates and Assumptions In preparing our financial statements, we make numerous estimates and assumptions that affect the amounts reported in these financial statements and accompanying notes. We must make these estimates and assumptions because certain information we use is dependent on future events, cannot be calculated with a high degree of precision from data available or simply cannot be readily calculated based on generally accepted methodologies. In preparing our financial statements, the more critical and subjective areas that deal with the greatest amount of uncertainty relate to our accounting for our long-lived assets, including recoverability, development costs, and final capping, closure and post-closure costs; our valuation allowances for accounts receivable and deferred tax assets; our liabilities for potential litigation, claims and assessments; our liabilities for environmental remediation, multiemployer pension funds, employee benefit plans, deferred taxes, uncertain tax positions, and insurance reserves; and our estimates of the fair values of assets acquired and liabilities assumed in any acquisition. Each of these items is discussed in more detail in our description of our significant accounting policies in Note 2, Summary of Significant Accounting Policies , of the Notes to Consolidated Financial Statements in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 . Our actual results may differ significantly from our estimates.
New Accounting Pronouncements	New Accounting Pronouncements Accounting Standards Adopted During 2018, we adopted the following accounting standard updates ("ASUs") as issued by the Financial Accounting Standard Board ("FASB"): ASU Effective Date ASU 2014-09 Revenue from Contracts with Customers (Topic 606) and Other Assets and Deferred Costs-Contracts with Customers (Subtopic 340-40) January 1, 2018 ASU 2016-15 Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments January 1, 2018 ASU 2016-18 Statement of Cash Flows (Topic 230) - Restricted Cash January 1, 2018 ASU 2017-01 Business Combinations (Topic 805) - Clarifying the Definition of Business January 1, 2018 ASU 2017-07 Compensation - Retirement Benefits (Topic 715) - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost January 1, 2018 ASU 2017-09 Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting January 1, 2018 Revenue Recognition Effective January 1, 2018, we adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606) and Other Assets and Deferred Costs-Contracts with Customers (Subtopic 340-40) ("ASU 2014-09" or the "new revenue recognition standard") using the modified retrospective approach. We recognized the cumulative effect of adopting the new revenue recognition standard as an adjustment to the beginning balance of Retained Earnings as of the date of adoption. The comparative periods have not been restated and continue to be reported under the accounting standards in effect for those periods. The timing and pattern of revenue recognition has not significantly changed under the new revenue recognition standard, nor has there been a material change to our operating or net income. Under ASU 2014-09, we record revenue when control is transferred to the customer, generally at the time we provide a service. While the timing and pattern of revenue recognition remains unchanged, we identified certain consideration payable to our customers that is now recorded as a reduction of revenue in accordance with the new revenue recognition standard. These costs were historically recorded as a component of cost of operations and include: • payments issued to our municipal customers in accordance with our residential collection contracts, • payments issued to our municipal customers in accordance with certain landfill operating agreements, and • commodity rebates in our collection and recycling lines of business. Historically, we also recognized certain upfront payments to acquire customer contracts as other assets in our consolidated balance sheet and amortized the asset as a component of depreciation, amortization and depletion over the respective contract life. In accordance with the new revenue recognition standard, we now amortize the asset as a reduction of revenue. The timing and pattern of recognizing these payments to our customers have not significantly changed under the new revenue recognition standard. In addition, we historically recognized sales commissions as a component of selling, general and administrative expenses as they were incurred. In accordance with the new revenue recognition standard, we identified certain sales commissions that represent an incremental cost of the contract and should be capitalized and amortized to selling, general and administrative expense over the average life of the customer relationship. The cumulative effect of the changes made to our consolidated balance sheet for the adoption of ASU 2014-09 were as follows: Balance at December 31, 2017 Adjustments due to our adoption of ASU 2014-09 Balance at January 1, 2018 Balance Sheet Assets Other assets $ 335.2 $ 43.8 $ 379.0 Liabilities Deferred income taxes and other long-term tax liabilities, net $ 796.4 $ 10.4 $ 806.8 Equity Retained earnings $ 4,152.5 $ 33.4 $ 4,185.9 The impact of our adoption of the new revenue recognition standard on our consolidated income statement for the three and six months ended June 30, 2018 was as follows: For the three months ended June 30, 2018 For the six months ended June 30, 2018 As Reported Effect of Change As Computed Excluding the Adoption of ASU 2014-09 As Reported Effect of Change As Computed Excluding the Adoption of ASU 2014-09 Income Statement Revenue $ 2,517.8 $ 82.9 $ 2,600.7 $ 4,945.2 $ 169.6 $ 5,114.8 Expenses: Cost of operations $ 1,577.2 $ 81.5 $ 1,658.7 $ 3,047.0 $ 166.8 $ 3,213.8 Depreciation, amortization and depletion $ 255.5 $ 1.4 $ 256.9 $ 518.6 $ 2.8 $ 521.4 Selling, general and administrative $ 252.9 $ (0.1 ) $ 252.8 $ 514.0 $ 0.4 $ 514.4 Operating income $ 408.2 $ 0.1 $ 408.3 $ 812.4 $ (0.4 ) $ 812.0 Statement of Cash flows Effective January 1, 2018 we adopted ASU 2016-15, Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments ("ASU 2016-15") using a retrospective approach to each period presented. In accordance with the standard, we recognize contingent consideration and holdbacks paid within three months of an acquisition's consummation date as cash outflows from investing activities in the statement of cash flows. Payments made thereafter are recognized as cash outflows from financing activities in the statement of cash flows. As the requirements of the standard do not significantly differ from our previous accounting policy, our adoption of this guidance did not have a material impact on our consolidated financial statements. Effective January 1, 2018 we adopted ASU 2016-18, Statement of Cash Flows (Topic 230) - Restricted Cash ("ASU 2016-18") using a retrospective approach to each period presented. As a result of our adoption of the standard, restricted cash and restricted cash equivalents are included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. Consequently, we reclassified the $3.0 million change in restricted cash and restricted cash equivalents from cash used in investing activities for the six months ended June 30, 2017 . Beginning-of-period and end-of-period cash, cash equivalents, restricted cash and restricted cash equivalents as presented in the statement of cash flows is reconciled as follows: June 30, 2018 December 31, 2017 June 30, 2017 December 31, 2016 Cash and cash equivalents $ 61.3 $ 83.3 $ 36.0 $ 67.8 Restricted cash and marketable securities 116.2 141.1 93.3 90.5 Less: restricted marketable securities (44.8 ) (45.3 ) (45.1 ) (45.3 ) Cash, cash equivalents, restricted cash and restricted cash equivalents $ 132.7 $ 179.1 $ 84.2 $ 113.0 Business Combinations Effective January 1, 2018 we adopted ASU 2017-01, Business Combinations (Topic 805) - Clarifying the Definition of Business ("ASU 2017-01"), which assists entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. ASU 2017-01 provides a screen that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. If the screen is not met, the entity then evaluates whether the set meets the requirement that a business include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs. The guidance prescribed by ASU 2017-01 will be applied prospectively to relevant transactions on or after the adoption date and did not have a material impact on the acquisitions accounted for as a business combination during the six months ended June 30, 2018 . Retirement Benefits Effective January 1, 2018 we adopted ASU 2017-07, Compensation - Retirement Benefits (Topic 715) - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost ("ASU 2017-07") using a retrospective approach to each period presented. The standard requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. As our pension plan is frozen, we do not have service costs that qualify for the treatment prescribed by ASU 2017-07. Subsequent to the adoption of ASU 2017-07, net benefit costs (income) are reported in other income. Our adoption of ASU 2017-07 did not have a material impact on our consolidated financial statements for the six months ended June 30, 2018 and 2017 . Stock Compensation Effective January 1, 2018, we adopted ASU 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting ("ASU 2017-09"), which provides clarification on when modification accounting should be used for changes to the terms or conditions of a share-based payment award. ASU 2017-09 does not change the accounting for modifications but clarifies that modification accounting guidance should only be applied if there is a change to the value, vesting conditions, or award classification and would not be required if the changes are considered non-substantive. The adoption of ASU 2017-09 did not have a material impact on our consolidated financial statements for the six months ended June 30, 2018 . Accounting Standards Issued but not yet Adopted Leases In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) ("ASU 2016-02"), which increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. ASU 2016-02 requires lessees to recognize lease assets and liabilities for most leases classified as operating leases under previous U.S. GAAP. The standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. As such, Republic will adopt the standard beginning January 1, 2019. As we progress to adopt the standard, we continually monitor clarifying interpretations. In January 2018, the FASB issued Proposed Accounting Standards Update, Leases (Topic 842) : Targeted Improvements , which proposed amending the guidance to add a method of adoption whereby the issuer may elect to recognize a cumulative-effect adjustment at the beginning of the period of adoption. We currently plan to adopt the standard under this proposed method in the event it is approved by the FASB. The comment deadline for the Exposure Draft was February 5, 2018, and a final decision is pending. Under ASU 2016-02, we will recognize a right-of-use asset and a right-of-use liability for leases classified as operating leases in our consolidated balance sheet. We continue to assess the overall impact to our consolidated financial statements, however, we currently plan to apply the package of practical expedients to leases that commenced before the effective date whereby we will elect to not reassess the following: (i) whether any expired or existing contracts contain leases; (ii) the lease classification for any expired or existing leases; and (iii) initial direct costs for any existing leases. We are assessing the disclosure requirements under ASU 2016-02, and we anticipate disclosing additional information, as necessary, to comply with the standard. To assist in quantifying the impact on our consolidated financial statements and supplementing our existing disclosures, we are in the process of implementing a software solution to manage and account for our leases. Derivatives and Hedging In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities ("ASU 2017-12"). ASU 2017-12 intends to address concerns through changes to hedge accounting guidance which will accomplish the following: a) Expand hedge accounting for nonfinancial and financial risk components and amend measurement methodologies to more closely align hedge accounting with a company's risk management activities; b) Decrease the complexity of preparing and understanding hedge results through eliminating the separate measurement and reporting of hedge ineffectiveness; c) Enhance transparency, comparability and understandability of hedge results through enhanced disclosures and changing the presentation of hedge results to align the effects of the hedging instrument and the hedged item; and d) Reduce the cost and complexity of applying hedge accounting by simplifying the manner in which assessments of hedge effectiveness may be performed. ASU 2017-12 is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted in any interim period following the issuance date. We are currently assessing the effect this guidance may have on our consolidated financial statements. Reclassifications of Certain Tax Effects from Accumulated Other Comprehensive Income In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income ("ASU 2018-02"). ASU 2018-02 allows the reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act (the "Tax Act"). Consequently, the amendments eliminate the stranded tax effects resulting from the Tax Act and will improve the usefulness of information reported to financial statement users. However, because the amendments only relate to the reclassification of the income tax effects of the Tax Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected. ASU 2018-02 is effective for all entities for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. We are currently assessing the effect this guidance may have on our consolidated financial statements. Income Taxes In March 2018, the FASB issued ASU 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 (SEC Update) which provides guidance on accounting for the tax effects of the Tax Act. See Note 8, Income Taxes for discussion on our adoption plans. Improvements to Nonemployee Share-Based Payment Accounting In June 2018, the FASB issued ASU 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting ("ASU 2018-07"). ASU 2018-07 simplifies several aspects of the accounting for nonemployee share-based payment transactions resulting from expanding the scope of Topic 718, Compensation—Stock Compensation, to include share-based payment transactions for acquiring goods and services from nonemployees. ASU 2018-07 is effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. We are currently assessing the effect this guidance may have on our consolidated financial statements.
