6.	CONTINGENCIES

(a)	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 the waste management business.

In accordance with 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 ASC 450-20-25-2. In instances where we determine that a loss is probable and we can reasonably estimate a range of losses 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 ASC 450-20-25-3. As of January 31, 2013, there were no accruals established related to our outstanding legal proceedings.

We offer no prediction of the outcome of any of the proceedings or negotiations described below. We are vigorously defending each of the unresolved lawsuits and claims described below. However, litigation is subject to inherent uncertainty and there can be no guarantee we will prevail or that any judgments against us, if sustained on appeal, will not have a material adverse effect on our business, financial condition, results of operations or cash flows.

Penobscot Energy Recovery Company Matter

On May 31, 2011, we received formal written notice from the Penobscot Energy Recovery Company (“PERC”) submitting to arbitration what it alleges is a disputed invoice in the amount of approximately $3,195 dated March 2, 2011. PERC contended that Pine Tree Waste, Inc., our subsidiary, failed since 2001 to honor a “put-or-pay” waste disposal arrangement. Arbitration of this matter was initiated, but in January 2012 a global settlement was reached in principle and memorialized in a letter of intent dated February 1, 2012, which documented the final terms of the settlement and dismissal of the arbitration action. The final global settlement documents were executed effective October 1, 2012. Pursuant to the terms of the settlement, we will not be required to make a cash payout. We anticipate that there may be nonmaterial incremental operational expenses that arise from implementing the terms of the settlement with regard to waste deliveries.

New York State Tax Litigation Matter

On January 18, 2011, certain of our subsidiaries doing business in New York State received a Notice of Deficiency (the “Notices”) from the New York State Department of Taxation and Finance asserting liability for corporation franchise tax for one or more of the tax years ended April 30, 2004 through April 30, 2006. The Notices, in the aggregate, assert liability of $3,852, comprising $2,220 of tax and $1,632 of penalties and interest. New York State has alleged that we are not permitted to file a single combined corporation franchise tax return with our subsidiaries for each of the years audited.

We filed Petitions for Redetermination (“Petitions”) with the State of New York Division of Tax Appeals on April 13-14, 2011, and an administrative hearing before a single tax tribunal administrative law judge on all Petitions that was scheduled for December 12, 2012 has been rescheduled to April 17-19, 2013. We expect to aggressively defend against this claim through the administrative adjudication and appeals process and the courts, if necessary. Under ASC 740, we believe our position will more likely than not be successful in contesting the deficiencies and consequently, we have not established any reserve for this matter.

(b)	Environmental 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 existing 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.

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, including the preparation of a Remedial Investigation and Feasibility Study (the “Study”). A draft of the Study was submitted to 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 will be approximately $10,219 and it is unlikely that any costs relating to onsite remediation will be incurred until fiscal year 2014. On February 28, 2011, the DEC issued a Proposal 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. A new Order on Consent and Administrative Settlement naming WSI and NiMo as Respondents was received by us on November 13, 2012, requiring that we enter into a Consent Order with DEC within 60 days and mandating implementation of the ROD. The deadline for execution of the Consent Order has recently been extended until March 27, 2013.

WSI is jointly and severally liable for the total cost to remediate and we initially expected to be responsible for approximately 30% upon implementation of a cost-sharing agreement with NiMo and GM. Based on these estimates, we recorded an environmental remediation charge of $2,823 in the third quarter of fiscal year 2009. In the fourth quarter of fiscal year 2009, we recognized an additional charge of $1,532, representing an additional 15% of the estimated costs, in recognition of the deteriorating financial condition and eventual bankruptcy filing of GM. In the fourth quarter of fiscal year 2010, we recognized an additional charge of $335 based on changes in the expected timing of cash outflows. Based on the estimated costs in the ROD, and changes in the estimated timing of cash flows, we recorded an environmental remediation charge of $549 in the fourth quarter of fiscal year 2011. Such charges could be significantly higher if costs exceed estimates. We inflate these estimated costs in current dollars until the expected time of payment and discount the cost to present value using a risk free interest rate (2.70%). At January 31, 2013 and April 30, 2012, we have recorded liabilities of $5,313 and $5,210, respectively, including the recognition of $34, $34, $103, and $103 of accretion expense in the three and nine months ended January 31, 2013 and 2012, respectively.

In September 2011, the DEC settled its environmental claim against the estate of the former GM (known as the “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. We expect the warrants to be issued in fiscal year 2013. We have not assumed that the payment of these claims will reduce our exposure.
