Colorado’s haze lawsuit tests coal plant closure | Analysis

Colorado is challenging the Environmental Protection Agency's refusal to approve its plan to reduce air pollution that hazes national parks and wilderness areas. The crux of the legal battle hinges on whether the federal government can mandate the closure of a coal-fired power plant using air quality regulations. This case could set a significant precedent for environmental regulation and the balance of state versus federal authority in environmental protection. If successful, Colorado could lead to stricter national standards for air quality affecting power plants.
