Pursuant to a legislative requirement, GAO reviewed the Environmental Protection Agency's (EPA) new rule on regional haze regulations. GAO noted that: (1) the rule calls for states to establish goals and emission reduction strategies for improving visibility in all 156 mandatory Class I national parks and wilderness areas; (2) specific provisions are included in the rule allowing nine western states to implement the recommendations of the Grand Canyon Visibility Transport Commission within the framework of the national regional haze program; and (3) EPA complied with applicable requirements in promulgating the rule.
