Subsequent Events [Abstract]
SUBSEQUENT EVENT	SUBSEQUENT EVENT On November 2, 2011, the Company announced that it expects to temporarily idle the hazardous waste incinerator in Ville Mercier, Quebec, for approximately eighteen months from the beginning of the first quarter of 2012. Factors influencing the decision include uncertainties over the local economic environment and the Company's ability to transfer waste streams to its other facilities. The Company has performed an analysis of the long-lived assets and concluded that there was no impairment from the temporary idling of the incinerator. The Company will continue to monitor for impairment as necessary. The Company expects to recognize idling costs and severance costs in the fourth quarter of 2011 which in the aggregate are not material.
