This action amends the Final Mandatory Reporting of Greenhouse Gases Rule to require reporters subject to the rule to provide: The name, address, and percentage ownership of their U.S. parent company(s); their primary North American Industry Classification System code(s) as well as all additional applicable North American Industry Classification System code(s); and an indication of whether or not any of their reported emissions are from a cogeneration unit. This final action also corrects an editorial error in revisions made to the General Provisions published earlier this year.
