Acquisitions [Abstract]
Acquisitions	5.ACQUISITIONS During the six months ended June 30, 2014, the Company acquired Screwbean Landfill, LLC (“Screwbean”), which owns land and permits to construct and operate an E&P waste facility, and S.A. Dunn & Company, LLC (“Dunn”), which owns land and permits to construct and operate an MSW landfill, for aggregate total cash consideration of $27,020 and contingent consideration of $2,923. The Company also acquired one individually immaterial non-hazardous solid waste collection business during the six months ended June 30, 2014. The Company acquired three individually immaterial non-hazardous solid waste collection businesses during the six months ended June 30, 2013. Contingent consideration represents the fair value of up to $3,000 of amounts payable to the former Dunn owners based on the successful modification of site construction permits that would enable increased capacity at the landfill. The fair value of the contingent consideration was determined using probability assessments of the expected future cash flows over the two-year period in which the obligations are expected to be settled, and applying discount rates ranging from 2.4% to 2.7%. Cash consideration for the acquisition of the business of R360 Environmental Solutions, Inc. (“R360”) in October 2012 included payment for the estimated net working capital of $18,906, as defined in the acquisition agreement, which was subject to final adjustment subsequent to the close of the acquisition. In March 2013, Waste Connections received $18,000 from the former owners of R360 due to the final adjustment to the net working capital that was estimated at the closing date. During the six months ended June 30, 2014 and 2013, the Company incurred $648 and $806, respectively, of acquisition-related costs. These expenses are included in Selling, general and administrative expenses in the Company’s Condensed Consolidated Statements of Net Income.
