-capable incinerator facilities, including the new incinerator in Kimball, Nebraska and we operate one active hazardous waste liquid injection incinerator in Canada. 

Commercial and Non-Commercial Landfills.    In the United States and Canada, we operate seven commercial landfills with approximately 26.4 million cubic yards of remaining highly probable airspace. Six of our commercial landfills are designed and permitted for the disposal of hazardous waste and one landfill is operated for non-hazardous industrial waste disposal and, to a lesser extent, municipal solid waste. In addition to our commercial landfills, we also own and operate one non-commercial landfill that only accepts waste from our on-site incinerator. See “Landfill Accounting” within Note 2, “Significant Accounting Policies,” to our consolidated financial statements included in Item 8 of this report for additional information on our commercial and non-commercial landfills.

Wastewater Treatment Facilities.    We operate a total of eleven facilities, of which nine are owned and two are leased, that offer a range of wastewater treatment technologies and services. Wastewater treatment consists primarily of three types of services: hazardous wastewater treatment, sludge dewatering or drying and non-hazardous wastewater treatment.

Treatment, Storage and Disposal Facilities.    We operate 33 TSDFs in the United States and Canada, of which 30 are owned and three are leased. Our TSDFs facilitate the treatment and movement of materials among our network of service centers and treatment and disposal facilities. Transportation may be accomplished by truck, rail, barge or a combination of modes, with our own assets or in conjunction with third-party transporters. Specially designed containment systems, vehicles and other equipment permitted for waste transport, together with drivers trained in transportation and waste handling procedures, provide for the movement of customer waste streams.

Other Hazardous Waste Management Properties.    We also operate eight facilities specializing in solvent recovery, seven owned and one leased, and we own and operate two autoclave facilities specifically designed to treat medical waste.
