The purpose and effect of this proposed rule is to amend rules identified in the Department's 2022-2023 Regulatory Plan as needing to be amended by adopting federal regulations by reference which incorporate conforming changes to Canada-specific hazardous waste import-export recovery and disposal operation codes as required to maintain the program’s equivalency with the Federal program under 40 CFR 271.10(e). The federal rule makes conforming changes to regulations related to twelve hazardous waste import-export recovery and disposal operations used in hazardous waste export and import notices submitted to EPA by U.S. exporters and importers, and in movement documents that accompany export and import shipments. The changes to regulations related to these twelve recovery and disposal operations are needed to reflect changes to regulations related to Canadian import-export recovery and disposal operations that Canada promulgated in the Canada Gazette Part II on March 17, 2021, and that become effective in Canada on October 31, 2021. Additionally, as the changes are being made solely to conform to Canada’s regulatory changes to Canada-specific operation codes and descriptions.
