From the text...'Federal agencies are subject to certain laws and requirements that are not necessarily applicable to states or private entities in the same manner or at all. Federal agencies are required to do long-range planning for management of the lands they manage through numerous agency-specific planning mandates. The National Environmental Policy Act (NEPA) requires Federal agencies to examine and disclose potential impacts of their actions on the environment. The General Conformity regulations require federal agencies to examine the effect of their actions on the ability of a state to reach air quality goals and modify their actions if air quality targets would be delayed. Federal agencies also manage wilderness areas and the Wilderness Act contains language with implications for air quality protection.'
