Assets Held for Sale [Abstract]
ACQUISITIONS AND DISPOSITIONS	ACQUISITIONS AND DISPOSITIONS The acquisitions in the section below are not material to our condensed consolidated financial statements individually or in the aggregate and therefore, disclosures of pro forma financial information have not been presented. The results of operations reflect the period of ownership of the acquired businesses, business development projects and dispositions. Environmental Services Acquisitions During the six months ended June 30, 2017, we acquired three environmental services businesses (one of which was accounted for as an asset purchase), in separate transactions, for approximately $17 million. These acquisitions expand our Covanta Environmental Solutions capabilities and client service offerings, and allow us to direct additional non-hazardous profiled waste volumes into our EfW facilities, and therefore are highly synergistic with our existing business. China Investments Prior to 2016, our interests in China included an 85% ownership of an EfW facility located in Jiangsu Province ("Taixing"), a 49% equity interest in an EfW facility located in Sichuan Province and a 40% equity interest in Chongqing Sanfeng Covanta Environmental Industry Co., a company located in the Chongqing Municipality that is engaged in the business of providing design and engineering, procurement, construction services and equipment sales for EfW facilities in China, as well as operating services for EfW facilities. During 2016, we completed the exchange of our ownership interests in China for a 15% ownership interest in Chongqing Sanfeng Covanta Environmental Industrial Group, Co., Ltd ("Sanfeng Environment") and subsequently sold approximately 90% of the aforementioned ownership interest in Sanfeng Environment to a third-party, a subsidiary of CITIC Limited ("CITIC"), a leading Chinese industrial conglomerate and investment company, pursuant to agreements entered into in July 2015. As a result, during the year ended December 31, 2016, we recorded a pre-tax gain of $41 million. We received pre-tax proceeds of $105 million. The gain resulted from the excess of pre-tax proceeds over the cost-method book value of $70 million, plus $5 million of realized gains on the related cumulative foreign currency translation adjustment, that were reclassified out of other comprehensive income. Subsequent to completing the exchange, Sanfeng Environment has made certain claims for indemnification under the agreement related to the condition of the facility in Taixing. During the three and six months ended June 30, 2017, we recorded a $2 million and $6 million charge, respectively, related to these claims, which is included in loss on asset sales on our condensed consolidated statement of operations. In 2016, in connection with these transactions, we entered into foreign currency exchange collars and forwards to hedge against rate fluctuations that impacted the cash proceeds in U.S. dollar terms. For more information, see Note 11. Derivative Instruments. As of June 30, 2017 and December 31, 2016, our remaining cost-method investment in Sanfeng Environment totaled $6 million and was included in our condensed consolidated balance sheet as a component of "Other assets." There were no impairment indicators related to our cost-method investment during the six months ended June 30, 2017.
