* Excludes lands of the Navajo Nation, where the Albuquerque District is the lead district for implementation of the NWP Program. ** Based on the nature of activities covered by these NWPs it is the opinion of the Corps they cannot reasonably be expected to result in a discharge to waters of the U.S. and should not require WQC. Nevertheless, the need for WQC for a given activity is ultimately up to the appropriate certifying authority to determine.
