Alexander: EPA boiler rule can’t be fixed without Congress

Alexander also questioned whether EPA has the legal authority to make needed changes to a key portion of the rule, and whether the agency has the time to fix the rule, which was long delayed and promulgated under a court order.

Alexander is seen as a centrist on several Clean Air Act issues, but for months has expressed major concerns about constraints facing EPA on the rule.

A number of industry groups and House Republicans are also targeting the rule, one of several they argue should be softened, delayed or scuttled.
