Solid Waste

We continue to seek methods to minimize the generation of hazardous wastes in our operations. The Resource Conservation and Recovery Act (“RCRA”) establishes standards for the management of solid and hazardous wastes. Besides affecting waste disposal practices, RCRA also addresses the environmental effects of certain past waste disposal operations, the recycling of wastes and the regulation of underground storage tanks (“USTs”) containing regulated substances. We have ongoing RCRA treatment and disposal operations at one of our RM&T facilities and primarily utilize offsite third-party treatment and disposal facilities. In 2011, Canada will implement a ban on the land application of certain wastes, and we are developing options to treat or dispose of these wastes consistent with these new restrictions. Ongoing waste handling and disposal-related costs, however, are not expected to be material.

In addition, Canada will be implementing a ban on the land application of certain wastes and we are reviewing options to treat or dispose of these wastes consistent with these new restrictions.

Besides affecting waste disposal practices, RCRA also addresses the environmental effects of certain past waste disposal operations, the recycling of wastes and the regulation of underground storage tanks ("USTs") containing regulated substances. Since the EPA has not yet promulgated implementing regulations for all provisions of RCRA and has not yet made clear the practical application of all the implementing regulations it has promulgated, the ultimate cost of compliance with this statute cannot be accurately estimated. In addition, new laws are being enacted and regulations are being adopted by various regulatory agencies on a continuing basis, and the costs of compliance with these new rules can only be broadly appraised until their implementation becomes more accurately defined.
