The Interior Department sent a revised version of a proposed rule for fracking regulations on federal land to the White House Office of Management and Budget for interagency review January 22. The rule would require companies to disclose fracking chemicals and address issues of well-bore integrity and flowback water. The revised rule replaces a version released last year that was widely criticized by the oil and gas industry and some state regulators as expensive and impractical. The rule will be finalized by July.
