REMEDIAL LIABILITIES

The changes to remedial liabilities from January 1, 2013 through December 31, 2014 were as follows (in thousands):



	Remedial Liabilities for Landfill Sites			Remedial Liabilities for Inactive Sites			Remedial Liabilities (Including Superfund) for Non-Landfill Operations			Total
Balance at January 1, 2013	$	5,829		$	81,564		$	95,953		$	183,346
Liabilities assumed in Evergreen acquisition	—			—			2,384			2,384
Accretion	281			3,302			3,212			6,795
Changes in estimates recorded to statement of income	(190		)	(2,813		)	(317		)	(3,320		)
Expenditures	(93		)	(7,599		)	(7,202		)	(14,894		)
Currency translation and other	(203		)	(192		)	(1,418		)	(1,813		)
Balance at December 31, 2013	5,624			74,262			92,612			172,498
Adjustments during the measurement period related to Evergreen	—			—			(536		)	(536		)
Accretion	266			2,975			2,913			6,154
Changes in estimates recorded to statement of (loss) income	(113		)	(2,645		)	40			(2,718		)
Expenditures	(109		)	(5,940		)	(12,070		)	(18,119		)
Currency translation and other	(248		)	(124		)	(1,786		)	(2,158		)
Balance at December 31, 2014	$	5,420		$	68,528		$	81,173		$	155,121

In 2014, the reduction in changes in estimates recorded to the statement of (loss) income was primarily related to estimated cost adjustments for remediation across various sites.

In 2013, the benefit resulting from changes in remedial liability estimates was primarily due to two sites. One site received site closure approval, which resulted in re-evaluating and removing certain compensation costs, and at the other site the Company received a favorable notification from the PRPs group which indicated that the Interim Remedial Measure work has been completed and was fully funded by a trust held by the regulatory agency and from funds collected from settling PRPs.

(9) REMEDIAL LIABILITIES (Continued)

Anticipated payments at December 31, 2014 (based on current estimated costs and anticipated timing of necessary regulatory approvals to commence work on remedial activities) for each of the next five years and thereafter are as follows (in thousands):



Year ending December 31,
2015	$	17,519
2016	19,623
2017	12,593
2018	11,377
2019	13,911
Thereafter	112,491
Undiscounted remedial liabilities	187,514
Less: Discount	(32,393		)
Total remedial liabilities	$	155,121

Based on currently available facts and legal interpretations, existing technology, and presently enacted laws and regulations, the Company estimates that its aggregate liabilities as of December 31, 2014 for future remediation relating to all of its owned or leased facilities and the Superfund sites for which the Company has current or potential future liability is approximately $155.1 million. The Company also estimates that it is reasonably possible that the amount of such total liabilities could be as much as $25.8 million more. Future changes in either available technology or applicable laws or regulations could affect such estimates of remedial liabilities. Since the Company's satisfaction of the liabilities will occur over many years, the Company cannot now reasonably predict the nature or extent of future changes in either available technology or applicable laws or regulations and the impact that those changes, if any, might have on the current estimates of remedial liabilities.

The following tables show, respectively, (i) the amounts of such estimated liabilities associated with the types of facilities and sites involved and (ii) the amounts of such estimated liabilities associated with each facility or site which represents at least 5% of the total and with all other facilities and sites as a group and as of December 31, 2014.

Estimates Based on Type of Facility or Site (in thousands):



Type of Facility or Site	Remedial Liability		% of Total		Reasonably Possible Additional Liabilities(1)
Facilities now used in active conduct of the Company's business (49 facilities)	$	72,565	46.8	%	$	13,358
Inactive facilities not now used in active conduct of the Company's business but most of which were acquired because the assumption of remedial liabilities for such facilities was part of the purchase price for the CSD assets (42 facilities)	68,527		44.2		11,023
Superfund sites owned by third parties (23 sites)	14,029		9.0		1,403
Total	$	155,121	100.0	%	$	25,784

(2)	$27.7 million of the $155.1 million remedial liabilities and $2.9 million of the $25.8 million reasonably possible additional liabilities include estimates of remediation liabilities related to the legal and administrative proceedings discussed in Note 16, "Commitments and Contingencies," as well as other such estimated remedial liabilities.

Revisions to remediation reserve requirements may result in upward or downward adjustments to income from operations in any given period. The Company believes that its extensive experience in the environmental services business, as well as its involvement with a large number of sites, provides a reasonable basis for estimating its aggregate liability. It is possible, however, that technological, regulatory or enforcement developments, the results of environmental studies, or other factors could necessitate the recording of additional liabilities or the revision of currently recorded liabilities that could be material. The impact of such future events cannot be estimated at the current time.
