* 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.
