2019 Wetland Delineation Report <br /> Tucson South Sand and Gravel Mine—Brighton, Colorado <br /> (USAGE 1987) and the Regional Supplement to the USACE Wetland Delineation Manual: Great <br /> Plains Region (Version 2.0) (USACE 2010). <br /> Fifteen features were delineated in the Project area (Figure 2) including eight wetlands (Table 3), <br /> six streams (Table 4), and two ponds (Table 5). Tetra Tech recommends consultation with the <br /> Denver Regulatory Office of USACE prior to construction to determine the jurisdictional status of <br /> these features and to identify the permitting requirements, if any, for the development of the <br /> project. The USACE typically issues Nationwide permits (NWPs) from the USACE allow for minor <br /> impacts in wetlands and other WOTUS that are jurisdictional under Section 404 of the CWA. A <br /> minor impact is generally less than 0.5 acre. When impacts to jurisdictional wetlands or other <br /> WOTUS exceed minor impacts, the USACE will generally require an Individual Permit. Should <br /> the project construction design include impacts to jurisdictional WOTUS greater than 0.5 acres, <br /> the project would likely be subject to an Individual Permit. <br /> 6.
