The Environmental Protection Agency agreed last week to respond by January 15 to a petition asking the agency to object to a Clean Air Act permit issued by Texas regulators to a Luminant Generation coal-fired power plant. The agency agreed to the deadline in a proposed consent decree reached in a lawsuit filed by the Environmental Integrity Project, the Sierra Club, and the Texas Campaign for the Environment. The plaintiffs asked the agency to object to the permit because it incorporated by reference a Texas Control Standard Permit, and asked the agency to object to or reopen the permit on the grounds that it did not include maximum achievable control technology limits for hazardous air pollutant emissions from the power plant as required by the Clean Air Act.
