This section describes the environmental consequences of the no-action and the action alternatives. First, the methods for assessing environmental consequences are discussed. NEPA requires consideration of context, intensity, and duration of impacts, and cumulative impacts. Next, is an explanation of resource impairment, which must also be assessed by alternative, according to National Park Service policy. Subsequent sections in this chapter are organized by impact topic, first for the no-action alternative, then alternative B, and then alternative C (the National Park Service-preferred alternative).
