Accounting Policies [Abstract]
Basis of Presentation	1. BASIS OF PRESENTATION Casella Waste Systems, Inc. (“Parent”), and its consolidated subsidiaries (collectively, “we”, “us” or “our”), is a regional, vertically-integrated solid waste services company that provides collection, transfer, disposal, landfill, landfill gas-to-energy, recycling and organics services in the northeastern United States. We market recyclable metals, aluminum, plastics, paper and corrugated cardboard, which have been processed at our recycling facilities, as well as recyclables purchased from third-parties. We manage our solid waste operations on a geographic basis through two regional operating segments, the Eastern and Western regions, each of which provides a full range of solid waste services, and our larger-scale recycling and commodity brokerage operations through our Recycling segment. Organics services, ancillary operations, major account and industrial services, discontinued operations and earnings from equity method investees are included in our Other segment. The accompanying unaudited consolidated financial statements, which include the accounts of the Parent, our wholly-owned subsidiaries and any partially owned entities over which we have a controlling financial interest, have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). All significant intercompany accounts and transactions are eliminated in consolidation. Investments in entities in which we do not have a controlling financial interest are accounted for under either the equity method or the cost method of accounting, as appropriate. Our significant accounting policies are more fully discussed in Item 8 of our Transition Report on Form 10-KT for the transition period ended December 31, 2014, which was filed with the SEC on February 27, 2015. Preparation of our consolidated financial statements in accordance with GAAP requires management to make certain estimates and assumptions. These estimates and assumptions affect the accounting for and recognition and disclosure of assets, liabilities, equity, revenues and expenses. We must make these estimates and assumptions because certain information that we use is dependent on future events, cannot be calculated with a high degree of precision given the available data, or simply cannot be readily calculated. In the opinion of management, these consolidated financial statements include all adjustments, which include normal recurring and nonrecurring adjustments, necessary for a fair presentation of the financial position, results of operations and cash flows for the periods presented. The results for the three and six months ended June 30, 2015 may not be indicative of the results for any other interim period or the entire fiscal year. The consolidated financial statements presented herein should be read in conjunction with our audited consolidated financial statements included in our Transition Report on Form 10-KT for the transition period ended December 31, 2014. Subsequent Events We have evaluated subsequent events or transactions that have occurred after the consolidated balance sheet date of June 30, 2015, but prior to the filing of the consolidated financial statements with the SEC on this Quarterly Report on Form 10-Q. We have determined that there are no subsequent events that require recognition or disclosure in this Quarterly Report on Form 10-Q.

Accounting Changes and Error Corrections [Abstract]
Accounting Pronouncements	2. ACCOUNTING PRONOUNCEMENTS New Accounting Pronouncements Pending Adoption Debt Issuance Costs In April 2015, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update for the presentation of debt issuance costs. The update provides that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability. This guidance is effective on a retrospective basis for annual reporting periods, and interim periods within those reporting periods, beginning after December 15, 2015, with early adoption permitted. We expect that this guidance will have no impact on our consolidated financial position or results of operations, and will only impact the presentation of, and disclosures in, our consolidated financial statements and notes thereto. Consolidation In February 2015, the FASB issued an accounting standards update for the requirements of consolidation. The update provides changes to the analysis that an entity must perform to determine whether it should consolidate certain types of legal entities because in certain situations deconsolidated financial statements are necessary to better analyze the reporting entity’s economic and operational results. This guidance is effective for annual reporting periods, and interim periods within those reporting periods, beginning after December 15, 2015, with early adoption permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. We expect that this guidance will have no impact on our consolidated financial position or results of operations. Extraordinary and Unusual Items In January 2015, the FASB issued an accounting standards update that eliminates the GAAP concept of extraordinary items. The update provides for the elimination of the requirements to consider whether an underlying event or transaction is extraordinary, but retains the presentation and disclosure guidance for items that are unusual in nature or occur infrequently and expands upon it to include items that are both unusual in nature and infrequently occurring. This guidance is effective prospectively or retrospectively for annual reporting periods, and interim periods within those reporting periods, beginning after December 15, 2015, with early adoption permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. We expect that this guidance will have no impact on our consolidated financial position or results of operations. Revenue Recognition In May 2014, the FASB issued an accounting standards update for the recognition of revenue, which supersedes existing revenue recognition requirements and most industry-specific guidance. The update provides that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance is effective for annual reporting periods, and interim reporting periods within those reporting periods, beginning after December 15, 2017 under either full or modified retrospective adoption. Early application is not permitted. We are currently assessing the potential impact this guidance may have on our consolidated financial statements as a result of adopting this standard. Adoption of New Accounting Pronouncements Discontinued Operations In April 2014, the FASB issued an accounting standards update for the requirements of reporting discontinued operations. The update provides that an entity or a group of components of an entity is required to be reported in discontinued operations once the component of an entity meets the held for sale criteria, is disposed of by sale, or is disposed of other than by sale only if the disposal represents a strategic shift that has, or will have, a major effect on an entity’s operations and financial results. The update also requires that additional disclosures about discontinued operations be made. This guidance is effective prospectively for annual reporting periods, and interim reporting periods within those reporting periods, beginning after December 15, 2014. We adopted this guidance effective January 1, 2015.

Accrued Final Capping, Closure and Post Closure	4. ACCRUED FINAL CAPPING, CLOSURE AND POST CLOSURE Accrued final capping, closure and post-closure costs include the current and non-current portion of costs associated with obligations for final capping, closure and post-closure of our landfills. We estimate our future final capping, closure and post-closure costs in order to determine the final capping, closure and post-closure expense per ton of waste placed into each landfill. The anticipated timeframe for paying these costs varies based on the remaining useful life of each landfill, as well as the duration of the post-closure monitoring period. The changes to accrued final capping, closure and post-closure liabilities for the six months ended June 30, 2015 and 2014 are as follows: Six Months Ended June 30, 2015 2014 Beginning balance $ 39,829 $ 46,326 Obligations incurred 1,116 1,640 Revisions in estimates (1) — (3,728 ) Accretion expense 1,665 1,876 Obligations settled (2) (984 ) (705 ) Ending balance $ 41,626 $ 45,409 (1) The revisions in estimates for final capping, closure and post-closure consisted of changes in cost estimates and the timing of final capping and closure events, as well as changes to expansion airspace and tonnage placement assumptions.

The additional 2019 Notes, which are fungible with and issued under the same indenture as the $325,000 2019 Notes previously issued, were issued at a discount of approximately $476 to be accreted over the remaining term of the 2019 Notes. On February 27, 2015, we used the net proceeds from this issuance, together with the initial borrowings under our new senior secured asset-based revolving credit and letter of credit facility (“ABL Facility”), to refinance our senior revolving credit and letter of credit facility that was due March 18, 2016 (“Senior Credit Facility”). Our ABL Facility consists of a revolving credit facility with loans thereunder being available up to an aggregate principal amount of $190,000, subject to availability under a borrowing base formula as defined in the ABL Facility agreement. We have the right to request, at our discretion, an increase in the amount of loans under the ABL Facility by an aggregate amount of $100,000, subject to the terms and conditions set forth in the ABL Facility agreement. Interest accrues at LIBOR plus between 1.75% and 2.50%, subject to the terms of the ABL Facility agreement, and is set at LIBOR plus 2.25% as of June 30, 2015. The ABL Facility matures on February 26, 2020. If we fail to refinance the 2019 Notes on or before November 16, 2018, the maturity date for the ABL Facility shall be November 16, 2018. The ABL Facility is guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries. As of June 30, 2015, our borrowing availability under the ABL Facility was $58,759 and was calculated as a borrowing base of $150,422, less revolver borrowings of $64,700, less outstanding irrevocable letters of credit totaling $26,963, at which date no amount had been drawn. The ABL Facility requires us to maintain a certain minimum consolidated EBITDA measured at the end of each fiscal quarter. Additionally, if borrowing availability does not meet certain thresholds as defined in the ABL Facility agreement, the ABL Facility requires us to meet additional covenants, including, without limitation: • a minimum fixed charge coverage ratio; and • a maximum consolidated first lien funded debt to consolidated EBITDA ratio. An event of default under any of our debt agreements could permit some of our lenders, including the lenders under the ABL Facility, to declare all amounts borrowed from them to be immediately due and payable, together with accrued and unpaid interest, or, in the case of the ABL Facility, terminate the commitment to make further credit extensions thereunder, which could, in turn, trigger cross-defaults under other debt obligations. If we were unable to repay debt to our lenders, or were otherwise in default under any provision governing our outstanding debt obligations, our secured lenders could proceed against us and against the collateral securing that debt. In conjunction with the refinancing of our Senior Credit Facility in February 2015, we were also required to settle an obligation associated with an interest rate derivative agreement held with a creditor to our Senior Credit Facility. In February 2015, we made a cash payment of $830 to settle our obligation associated with this interest rate swap. Loss on Debt Extinguishment As a result of the refinancing of the Senior Credit Facility, in the quarter ended March 31, 2015 we recorded a charge of $521 as a loss on debt extinguishment related to the write-off of deferred financing costs in connection with changes to the borrowing capacity from the Senior Credit Facility to the ABL Facility. The remaining unamortized deferred financing costs of the Senior Credit Facility, along with fees paid to the creditor and third-party costs incurred for the ABL Facility, are to be amortized over the term of the ABL Facility.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	6. COMMITMENTS AND CONTINGENCIES Legal Proceedings In the ordinary course of our business and as a result of the extensive governmental regulation of the solid waste industry, we are subject to various judicial and administrative proceedings involving state and local agencies. In these proceedings, an agency may seek to impose fines or to revoke or deny renewal of an operating permit held by us. From time to time, we may also be subject to actions brought by special interest or other groups, adjacent landowners or residents in connection with the permitting and licensing of landfills and transfer stations, or alleging environmental damage or violations of the permits and licenses pursuant to which we operate. In addition, we have been named defendants in various claims and suits pending for alleged damages to persons and property, alleged violations of certain laws and alleged liabilities arising out of matters occurring during the ordinary operation of a waste management business. In accordance with FASB Accounting Standards Codification (“ASC”) 450-20, we accrue for legal proceedings when losses become probable and reasonably estimable. As of the end of each applicable reporting period, we review each of our legal proceedings to determine whether it is probable, reasonably possible or remote that a liability has been incurred and, if it is at least reasonably possible, whether a range of loss can be reasonably estimated under the provisions of FASB ASC 450-20. In instances where we determine that a loss is probable and we can reasonably estimate a range of loss we may incur with respect to such a matter, we record an accrual for the amount within the range that constitutes our best estimate of the possible loss. If we are able to reasonably estimate a range, but no amount within the range appears to be a better estimate than any other, we record an accrual in the amount that is the low end of such range. When a loss is reasonably possible, but not probable, we will not record an accrual, but we will disclose our estimate of the possible range of loss where such estimate can be made in accordance with FASB ASC 450-20. Greenwood Street Landfill, Worcester, Massachusetts On July 2, 2014, we received a draft Administrative Consent Order with Penalty and Notice of Noncompliance (“Draft Order”) from the Massachusetts Department of Environmental Protection (“MADEP”) alleging that a subsidiary, NEWS of Worcester, LLC, had completed substantive closure of a portion of the Greenwood Street Landfill in Worcester, Massachusetts in 2010, at an elevation exceeding the applicable permit condition. While we neither admitted nor denied the allegations in the Draft Order, a final Administrative Consent Order with Penalty and Notice of Noncompliance was executed on March 20, 2015 (“Final Order”), and we agreed to pay a civil administrative penalty in a total amount of $172. MADEP agreed that $129 of that amount could be paid as a Supplemental Environmental Project for work being done by the Massachusetts Audubon Society at the Broad Meadow Brook Conservation Center & Wildlife Sanctuary in Worcester, Massachusetts, scheduled to be paid in full within a year of execution of the Final Order. Environmental Remediation Liability We are subject to liability for environmental damage, including personal injury and property damage, that our solid waste, recycling and power generation facilities may cause to neighboring property owners, particularly as a result of the contamination of drinking water sources or soil, possibly including damage resulting from conditions that existed before we acquired the facilities. We may also be subject to liability for similar claims arising from off-site environmental contamination caused by pollutants or hazardous substances if we or our predecessors arrange or arranged to transport, treat or dispose of those materials. The following matter represents our outstanding material claim. Potsdam Environmental Remediation Liability On December 20, 2000, the State of New York Department of Environmental Conservation (“DEC”) issued an Order on Consent (“Order”) which named Waste-Stream, Inc. (“WSI”), our subsidiary, General Motors Corporation (“GM”) and Niagara Mohawk Power Corporation (“NiMo”) as Respondents. The Order required that the Respondents undertake certain work on a 25-acre scrap yard and solid waste transfer station owned by WSI in Potsdam, New York, including the preparation of a Remedial Investigation and Feasibility Study (“Study”). A draft of the Study was submitted to the DEC in January 2009 (followed by a final report in May 2009). The Study estimated that the undiscounted costs associated with implementing the preferred remedies would be approximately $10,219. On February 28, 2011, the DEC issued a Proposed Remedial Action Plan for the site and accepted public comments on the proposed remedy through March 29, 2011. We submitted comments to the DEC on this matter. In April 2011, the DEC issued the final Record of Decision (“ROD”) for the site. The ROD was subsequently rescinded by the DEC for failure to respond to all submitted comments. The preliminary ROD, however, estimated that the present cost associated with implementing the preferred remedies would be approximately $12,130. The DEC issued the final ROD in June 2011 with proposed remedies consistent with its earlier ROD. An Order on Consent and Administrative Settlement naming WSI and NiMo as Respondents was executed by the Respondents and DEC with an effective date of October 25, 2013. It is unlikely that any significant expenditures relating to onsite remediation will be incurred until the fiscal year ending December 31, 2016. WSI is jointly and severally liable with the other Respondents for the total cost to remediate. In September 2011, the DEC settled its environmental claim against the estate of the former GM (known as “Motors Liquidation Trust”) for future remediation costs relating to the WSI site for face value of $3,000. In addition, in November 2011 we settled our own claim against the Motors Liquidation Trust for face value of $100. These claims will be paid by GM in warrants to obtain stock of the reorganized GM. GM has issued warrants to us beginning in May 2013 and at this time there is no way to accurately estimate when the remainder of these claims will be paid. We have not assumed that any future proceeds from the sale of securities received in payment of these claims will reduce our exposure. We have recorded an environmental remediation liability associated with the Potsdam site based on incurred costs to date and estimated costs to complete the remediation in other accrued liabilities and other long-term liabilities. Our expenditures could be significantly higher if costs exceed estimates. We inflate the estimated costs in current dollars to the expected time of payment and discount the total cost to present value using a risk free interest rate of 1.7%. The changes to the environmental remediation liability associated with the Potsdam environmental remediation liability for the six months ended June 30, 2015 and 2014 are as follows: Six Months Ended June 30, 2015 2014 Beginning balance $ 5,142 $ 5,421 Revisions in estimates (1) — (118 ) Accretion expense 40 69 Obligations settled — (28 ) Ending balance $ 5,182 $ 5,344 (1) Associated with changes in estimated future costs to complete the remediation, the discount rate and/or the portion of the total remediation costs that we are responsible for.

Equity [Abstract]
Stockholders' Equity	7. STOCKHOLDERS’ EQUITY Stock Based Compensation Shares Available For Issuance In the fiscal year ended April 30, 2007, we adopted the 2006 Stock Incentive Plan (“2006 Plan”). The 2006 Plan was amended in the fiscal year ended April 30, 2010. Under the 2006 Plan, we may grant awards up to an aggregate amount of shares equal to the sum of: (i) 2,475 shares of Class A common stock (subject to adjustment in the event of stock splits and other similar events), plus (ii) such additional number of shares of Class A common stock as are currently subject to options granted under our 1993 Incentive Stock Option Plan, 1994 Non-statutory Stock Option Plan, 1996 Option Plan, and 1997 Stock Option Plan (“Prior Plans”), which are not actually issued under the Prior Plans because such options expire or otherwise result in shares not being issued. As of June 30, 2015, there were 1,110 Class A common stock equivalents available for future grant under the 2006 Plan, inclusive of additional Class A common stock equivalents that were previously issued under our terminated plans and have become available for grant because such awards expired or otherwise resulted in shares not being issued. Stock Options Options under the 2006 Plan are granted at a price equal to the prevailing fair market value of our Class A common stock at the date of grant. Generally, options granted have a term not to exceed ten years and vest over a one to four year period from the date of grant. A summary of stock option activity for the six months ended June 30, 2015 is as follows: Stock Options Weighted Weighted Aggregate Outstanding, December 31, 2014 1,380 $ 7.70 Granted — $ — Exercised — $ — Forfeited (132 ) $ 12.02 Outstanding, June 30, 2015 1,248 $ 7.25 5.3 $ 903 Exercisable, June 30, 2015 726 $ 9.13 3.2 $ 383 Expected to vest, June 30, 2015 1,247 $ 7.25 5.3 $ 902 Stock-based compensation expense for stock options was $160 and $317 during the three and six months ended June 30, 2015, respectively, as compared to $105 and $215 during the three and six months ended June 30, 2014, respectively. As of June 30, 2015, total unrecognized stock-based compensation expense related to outstanding stock options was $772, which will be recognized over a weighted average period of 1.1 years. Other Stock Awards We grant restricted stock awards, restricted stock units and performance stock units under the 2006 Plan at a price equal to the fair market value of our Class A common stock at the date of grant. Restricted stock awards granted to non-employee directors vest incrementally over a three year period beginning on the first anniversary of the date of grant. Restricted stock units vest incrementally over an identified service period beginning on the grant date based on continued employment. Performance stock units vest on the third fiscal year-end following the grant date and are based on our attainment of a targeted average return on net assets as of the vesting date. A summary of restricted stock, restricted stock unit and performance stock unit activity for the six months ended June 30, 2015 is as follows: Restricted Stock, Weighted Weighted Average Aggregate Intrinsic Outstanding, December 31, 2014 1,048 $ 4.79 Granted 562 $ 4.20 Class A Common Stock vested (306 ) $ 4.72 Forfeited (280 ) $ 5.11 Outstanding, June 30, 2015 1,024 $ 4.40 2.2 $ 1,252 Expected to vest, June 30, 2015 844 $ 4.40 2.1 $ 1,029 (1) Performance stock units are included at the 100% attainment level. As of June 30, 2015, no performance stock units remain outstanding. Stock-based compensation expense related to restricted stock and restricted stock units was $594 and $1,080 during the three and six months ended June 30, 2015, respectively, as compared to $410 and $858 during the three and six months ended June 30, 2014, respectively. During the three and six months ended June 30, 2015, the total fair value of other stock awards vested was $1,701 and $1,713, respectively. As of June 30, 2015, total unrecognized compensation expense related to outstanding restricted stock and restricted stock units was $3,256, which will be recognized over a weighted average period of 2.1 years. We also recorded $21 and $38 of stock-based compensation expense related to our Employee Stock Purchase Plan during the three and six months ended June 30, 2015, respectively, as compared to $22 and $40 during the three and six months ended June 30, 2014, respectively. Accumulated Other Comprehensive Income The change in the balance of accumulated other comprehensive income, which is included as a component of our stockholders’ deficit, for the six months ended June 30, 2015 is as follows: Marketable Balance as of December 31, 2014 $ 58 Other comprehensive loss before reclassifications (31 ) Amounts reclassified from accumulated other comprehensive loss — Net current-period other comprehensive loss (31 ) Balance as of June 30, 2015 $ 27 Recent Stockholder Events On April 7, 2015, JCP Investment Partnership, LP notified us of its intention to nominate Brett W. Frazier, James C. Pappas and Joseph B. Swinbank for election as directors at our 2015 Annual Meeting of Stockholders in opposition to the three candidates that will be recommended for election by our Board of Directors. According to the Schedule 13D filed with the SEC by JCP Investment Partnership, LP, JCP Single-Asset Partnership, LP, JCP Investment Partners, LP, JCP Investment Holdings, LLC, JCP Investment Management, LLC and James C. Pappas (collectively, the “JCP Group”) on April 28, 2015, the JCP Group beneficially owns approximately 5.0% of our outstanding Class A common stock. On April 29, 2015, the JCP Group filed with the SEC soliciting material under Rule 14a-12 of the Exchange Act confirming its intention to file a preliminary proxy statement and an accompanying proxy card with the SEC to solicit votes for the election of the JCP Group’s slate of three director nominees to our Board of Directors, at our 2015 Annual Meeting of Stockholders. On May 29, 2015, the JCP Group filed with the SEC soliciting material under Rule 14a-12 of the Exchange Act reconfirming such intention.

Fair Value of Financial Instrum

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	9. FAIR VALUE OF FINANCIAL INSTRUMENTS We use a three-tier fair value hierarchy to classify and disclose all assets and liabilities measured at fair value on a recurring basis, as well as assets and liabilities measured at fair value on a non-recurring basis, in periods subsequent to their initial measurement. These tiers include: Level 1, defined as quoted market prices in active markets for identical assets or liabilities; Level 2, defined as inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; and Level 3, defined as unobservable inputs that are not corroborated by market data. We use valuation techniques that maximize the use of market prices and observable inputs and minimize the use of unobservable inputs. In measuring the fair value of our financial assets and liabilities, we rely on market data or assumptions which we believe market participants would use in pricing an asset or a liability. Assets and Liabilities Accounted for at Fair Value on a Recurring Basis Our financial instruments include cash and cash equivalents, restricted investments held in trust on deposit with various banks as collateral for our obligations relative to our landfill final capping, closure and post-closure costs, restricted cash reserved to finance certain capital projects in the State of New York, trade receivables, interest rate derivatives, trade payables and long-term debt. The carrying values of cash and cash equivalents, trade receivables and trade payables approximate their respective fair values due to their short-term nature. The fair value of restricted investments held in trust and escrow accounts is included as restricted assets in the Level 1 tier below, along with restricted cash reserved for repayment of certain capital projects in the State of New York. The fair value of the interest rate derivative, included in the Level 2 tier below, is calculated based on the three month LIBOR yield curve that is observable at commonly quoted intervals for the full term of the interest rate swap, adjusted by the credit risk of us and our counter-party based on the observable credit default swap rate. As of June 30, 2015 our assets and liabilities measured at fair value on a recurring basis included the following: Fair Value Measurement at June 30, 2015 Using: Quoted Prices in Significant Other Significant Assets: Restricted assets - capital projects $ 142 $ — $ — Restricted assets - landfill closure 826 — — Total $ 968 $ — $ — Liabilities: Interest rate derivative $ — $ 583 $ — As of December 31, 2014 our assets and liabilities measured at fair value on a recurring basis included the following: Fair Value Measurement at December 31, 2014 Using: Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets: Restricted assets - capital projects $ 5,819 $ — $ — Restricted assets - landfill closure 813 — — Total $ 6,632 $ — $ — Liabilities: Interest rate derivatives $ — $ 1,668 $ — Fair Value of Debt As of June 30, 2015, the fair value of our fixed rate debt, including our 2019 Notes, Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2005R-2 (“FAME Bonds 2005R-2”), Vermont Economic Development Authority Solid Waste Disposal Long-Term Revenue Bonds Series 2013 (“Vermont Bonds”), New York State Environmental Facilities Corporation Solid Waste Disposal Revenue Bonds Series 2014 (“New York Bonds”) and Solid Waste Disposal Revenue Bonds Series 2013 issued by the Business Finance Authority of New Hampshire (“New Hampshire Bonds”) was approximately $462,304 and the carrying value was $458,400. The fair value of the 2019 Notes are considered to be Level 1 within the fair value hierarchy as the fair value is based off of a quoted market price in an active market. The fair value of the FAME Bonds 2005R-2, the Vermont Bonds, the New York Bonds and the New Hampshire Bonds is considered to be Level 2 within the fair value hierarchy as the fair value is determined using market approach pricing that utilizes pricing models and pricing systems, mathematical tools and judgment to determine the evaluated price for the security based on the market information of each of the bonds or securities with similar characteristics. Although we have determined the estimated fair value amounts of the FAME Bonds 2005R-2, the Vermont Bonds, the New York Bonds and the New Hampshire Bonds using available market information and commonly accepted valuation methodologies, a change in available market information, and/or the use of different assumptions and/or estimation methodologies could have a material effect on the estimated fair values. These amounts have not been revalued, and current estimates of fair value could differ significantly from the amounts presented. As of June 30, 2015, the fair value of our ABL Facility approximated its carrying value of $64,699 based on current borrowing rates for similar types of borrowing arrangements, or Level 2 inputs. The carrying value of our remaining material variable rate debt, the Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2005R-1, approximates fair value because the interest rate for the debt instrument is based on a market index that approximates current market rates for instruments with similar risk and maturities.

Divestiture Transactions	10. DIVESTITURE TRANSACTIONS Sale of Business In the three months ended June 30, 2015, we divested of a business, which included the sale of certain assets associated with various waste collection routes in the Western region, for total consideration of $872, resulting in a gain of $677 in the three months ended June 30, 2015. Maine Energy In the fiscal year ended April 30, 2013, we executed a purchase and sale agreement with the City of Biddeford, Maine, pursuant to which we agreed to sell the real property of Maine Energy Recovery Company, LP (“Maine Energy”) to the City of Biddeford. We agreed to sell Maine Energy for an undiscounted purchase consideration of $6,650, which is being paid to us in equal installments over twenty-one years. The transaction closed in November 2012. In December 2012, we ceased operations of the Maine Energy facility and initiated the decommissioning, demolition and site remediation process in accordance with the provisions of the agreement. We have completed the demolition process, and have nearly completed site remediation under the auspices and in accordance with work plans approved by the Maine Department of Environmental Protection and the U.S. Environmental Protection Agency. The time for completion of this project has been consensually extended by us and the City of Biddeford, and we expect to complete this project and transfer ownership of the real property to the City of Biddeford during the summer of 2015. In consideration of the fact that the project is substantially complete and based on incurred costs to date and estimates regarding the remaining costs to fulfill our obligation under the agreement, we reversed a reserve of $1,157 of excess costs to complete the divestiture in the quarter ended March 31, 2015. As of June 30, 2015, we have accrued $96 in other accrued liabilities for the estimated remaining costs to fulfill our obligation under the agreement. CARES and Related Transaction Casella-Altela Regional Environmental Services, LLC (“CARES”) is a joint venture that owned and operated a water and leachate treatment facility for the natural gas drilling industry in Pennsylvania. Our joint venture partner in CARES is Altela, Inc. (“Altela”). We hold an ownership interest in CARES of 51% and, in accordance with FASB ASC 810-10-15, we consolidate the assets, liabilities and results of operations of CARES into our consolidated financial statements due to our controlling financial interest in the joint venture. In the fiscal year ended April 30, 2014, we determined that assets of the CARES water treatment facility were no longer operational or were not operating within product performance parameters. As a result, we initiated a plan to abandon and shut down the operations of CARES. It was determined that the carrying value of the assets of CARES was no longer recoverable and, as a result, the carrying value of the asset group was assessed for impairment and impaired in the three months ended June 30, 2014. As a result, we recorded an impairment charge of $7,455 in the three and six months ended June 30, 2014 to the asset group of CARES in the Western region. We executed a purchase and sale agreement on February 9, 2015 pursuant to which we and Altela agreed to sell certain assets of the CARES water treatment facility to an unrelated third-party. We sold these assets of CARES for purchase consideration of $3,500, resulting in a gain of $2,850 in the quarter ended March 31, 2015, 49% of which was attributable to Altela, the noncontrolling interest holder. As of June 30, 2015, we were proceeding with the dissolution of CARES in accordance with the CARES Limited Liability Company Agreement In connection with this transaction, we also sold certain of our equipment and real estate to the same unrelated third-party for total consideration of $1,050, resulting in a gain of $928 in the quarter ended March 31, 2015.

Segment Reporting	11. SEGMENT REPORTING We report selected information about operating segments in a manner consistent with that used for internal management reporting. We classify our solid waste operations on a geographic basis through regional operating segments. Revenues associated with our solid waste operations are derived mainly from solid waste collection and disposal, landfill, landfill gas-to-energy, transfer and recycling services in the northeastern United States. Our revenues in the Recycling segment are derived from municipalities and customers in the form of processing fees, tipping fees and commodity sales. Organics services, ancillary operations, major account and industrial services, discontinued operations, and earnings from equity method investees are included in our Other segment.

Accounting Changes and Error Corrections [Abstract]
New Accounting Policies Adopted and Pending Adoption	New Accounting Pronouncements Pending Adoption Debt Issuance Costs In April 2015, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update for the presentation of debt issuance costs. The update provides that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability. This guidance is effective on a retrospective basis for annual reporting periods, and interim periods within those reporting periods, beginning after December 15, 2015, with early adoption permitted. We expect that this guidance will have no impact on our consolidated financial position or results of operations, and will only impact the presentation of, and disclosures in, our consolidated financial statements and notes thereto. Consolidation In February 2015, the FASB issued an accounting standards update for the requirements of consolidation. The update provides changes to the analysis that an entity must perform to determine whether it should consolidate certain types of legal entities because in certain situations deconsolidated financial statements are necessary to better analyze the reporting entity’s economic and operational results. This guidance is effective for annual reporting periods, and interim periods within those reporting periods, beginning after December 15, 2015, with early adoption permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. We expect that this guidance will have no impact on our consolidated financial position or results of operations. Extraordinary and Unusual Items In January 2015, the FASB issued an accounting standards update that eliminates the GAAP concept of extraordinary items. The update provides for the elimination of the requirements to consider whether an underlying event or transaction is extraordinary, but retains the presentation and disclosure guidance for items that are unusual in nature or occur infrequently and expands upon it to include items that are both unusual in nature and infrequently occurring. This guidance is effective prospectively or retrospectively for annual reporting periods, and interim periods within those reporting periods, beginning after December 15, 2015, with early adoption permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. We expect that this guidance will have no impact on our consolidated financial position or results of operations. Revenue Recognition In May 2014, the FASB issued an accounting standards update for the recognition of revenue, which supersedes existing revenue recognition requirements and most industry-specific guidance. The update provides that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance is effective for annual reporting periods, and interim reporting periods within those reporting periods, beginning after December 15, 2017 under either full or modified retrospective adoption. Early application is not permitted. We are currently assessing the potential impact this guidance may have on our consolidated financial statements as a result of adopting this standard. Adoption of New Accounting Pronouncements Discontinued Operations In April 2014, the FASB issued an accounting standards update for the requirements of reporting discontinued operations. The update provides that an entity or a group of components of an entity is required to be reported in discontinued operations once the component of an entity meets the held for sale criteria, is disposed of by sale, or is disposed of other than by sale only if the disposal represents a strategic shift that has, or will have, a major effect on an entity’s operations and financial results. The update also requires that additional disclosures about discontinued operations be made. This guidance is effective prospectively for annual reporting periods, and interim reporting periods within those reporting periods, beginning after December 15, 2014. We adopted this guidance effective January 1, 2015.
