Map(s)/Figure(s) are attached to the AJD provided to the requestor. 2 If the navigable water is not subject to the ebb and flow of the tide or included on the District's list of Rivers and Harbors Act Section 10 navigable waters list, do NOT use this document to make the determination. The District must continue to follow the procedure outlined in 33 CFR part 329.14 to make a Rivers and Harbors Act Section 10 navigability determination. 3 A stand-alone TNW determination is completed independently of a request for an AJD. A stand-alone TNW determination is conducted for a specific segment of river or stream or other type of waterbody, such as a lake, where independent upstream or downstream limits or lake borders are established. A stand-alone TNW determination should be completed following applicable guidance and should NOT be documented on the AJD form. 4 Some excluded waters, such as (b)(2) and (b)(4), may not be specifically identified on the AJD form unless a requestor specifically asks a Corps district to do so. Corps Districts may, in case -by -case instances, choose to identify some or all of these waters within the review area. 5 Because of the broad nature of the (b)(1) exclusion and in an effort to collect data on specific types of waters that would be covered by the (b)(1) exclusion, four sub -categories of (b)(1) exclusions were administratively created for the purposes of the AJD Form. These four sub -categories are not new exclusions, but are simply administrative distinctions and remain (b)(1) exclusions as defined by the NWPR. Page 2 of 3 Form Version 29 July 2020—updated
