NOTE 1. DESCRIPTION OF BUSINESS

US Ecology, Inc. was most recently incorporated as a Delaware corporation in May 1987 as American Ecology Corporation. On February 22, 2010 the Company changed its name from American Ecology Corporation to US Ecology, Inc. US Ecology, Inc., through its subsidiaries, is a leading North American provider of environmental services to commercial and government entities. The Company addresses the complex waste management needs of its customers, offering treatment, disposal and recycling of hazardous and radioactive waste, as well as a wide range of complementary field and industrial services. Headquartered in Boise, Idaho, with operations in the United States, Canada and Mexico, US Ecology, Inc. has been protecting the environment since 1952. Throughout these financial statements words such as "we," "us," "our," "US Ecology" and the "Company" refer to US Ecology, Inc. and its subsidiaries.

On June 17, 2014, the Company acquired 100% of the outstanding shares of EQ Holdings, Inc. and its wholly-owned subsidiaries (collectively "EQ"). The acquisition of EQ significantly expanded the Company's service offerings, specifically in the areas of field and industrial services. As such, we have made changes to the manner in which we manage our business, make operating decisions and assess our performance. Under our new structure, our operations are managed in two reportable segments reflecting our internal reporting structure and nature of services offered: Environmental Services and Field & Industrial Services.

Our Environmental Services segment provides a broad range of hazardous material management services including the transportation, recycling, treatment and disposal of hazardous and non-hazardous waste at Company-owned landfill, wastewater and other treatment facilities.

Our Field & Industrial Services segment provides packaging and collection of hazardous waste and total waste management solutions at customer sites and through our 10-day storage facilities. Services include on-site management, waste characterization, transportation and disposal of non-hazardous and hazardous waste. This segment also provides specialty services such as high-pressure cleaning, tank cleaning, decontamination, remediation, transportation, spill cleanup and emergency response and other services to commercial and industrial facilities and to government entities. On November 1, 2015, we sold our Allstate Power Vac, Inc. ("Allstate") subsidiary, which was previously reported as part of our Field & Industrial Services segment, to a private investor group.
