The Environmental Protection Agency reproposed a rule February 24 that would treat requests from oil and gas companies to extend their use of alternate emissions reporting methods as confidential business information. At the same time, more than 60 other characteristics of the equipment would not be classified as confidential and could be disclosed. The agency is reproposing the confidential business information determinations for the companies because of significant changes to certain data elements since its last proposal. The rule would also defer until 2015 the requirement for oil and gas companies to report some of the inputs used for emissions calculations.
