President Biden's EPA is expected to draft interim auto emissions standards based on an agreement last year between California and five car companies, according to sources following the matter. EPA is poised to unveil the interim standards and notify the auto industry by April 1. \"I'm convinced that they're going to adopt the California standards,\" said Margo Oge, the former head of EPA's transportation office under the Obama and Clinton administrations. That's less stringent than the clean car standards established by former President Obama, which mandated a 5% annual increase. If EPA says the California deal will become national in scope, the agency likely would do so before April 1, sources said.
