BULL SEEP -CAMAS WETLAND~.MEATION REPORT • <br />APPENDIX <br />JURISDICTIONAL REQUIREMENTS <br />Section 404 of dte Clean Water Act of 1977, revised 1992, slates that a pertni[ may be needed for the discharge ofdredged or fill material into <br />Waters of the US, including wetlands. <br />Wedand delineation studies are required by We Act in order [o determine potential eRec¢ of dredge or fill activities in navigable waters, waters <br />of the United States or wetlands. Dredge material is that which is excavated or dredged from water and wetlands. Fill material is that which is <br />used for the primary purpose of replacing an arcs of a water body with dry land or for changing the bottom elevation of a water body. <br />The result of this Act wnceming Waters of the US is that at any time material is to be put into or taken from a stream or adjacent wctlands; <br />compliance with the Act must be achieved. The principal responsibility for regulating the Clean Water Act lies with the US Army Corps of <br />Engineers. Other agencies with which permitting must be coordinated include the US Environmental Protection Agency, the US Fish and <br />Wildlife Service, and state agencies including agencies concerned with wildlife and water quality. <br />METHODOLOGY <br />A. Inventory, Mapping and Sampling <br />Potential wetland areas to be studied were determined from a comprehensive level survey of wctlands hazed on vegetation and soil sampling. All <br />potential areas were examined using the three-parameter approach for hydric characteristics described below. Wetlands previously delineated <br />were verified during the field investigations. Maps of wetlands occurzing in the project site have been prepared a[ a scale of I "=300' from <br />existing topographic maps and aerial photography. Maps were field checked and potential wetlands were characterized using the guidelines <br />described in: Department of the Army, Waterways E<perimen[ Station, Corps of Engineers - Corps oFEnginecrs Wetlands Delineation Manuaf <br />(Department of the Artny, 1987). These guidelines are used to deternine wctlands on the bazis of intcrtelated analyses of vegetation, soils, and <br />hydrology described below A given area must contain evidence of each o(the three indicators to be considered ajurisdicti°nal wetland. <br />Diagnostic characterrstics used in identifying wctlands Thal occur in the project area for each of the three factors in the multi-parameter analysis <br />arc az follows: <br />t. Vegetation: The predominance of plant species that are typically adapted to life witliin habitats that have pernanen[ or altema[ing dry and <br />inundated and/or saturated soil conditions. The following clazsiGcations of plans az indicators of wetland ornon-wetland conditions apply to <br />this cntcrion (Reed, 1988): <br />• upland species are almost always found in uplands (>99°e probability) <br />• facultative upland species are commonly found in uplands, but may occur in wetlands (1- 33 % probability) <br />• facultative species may or may not occur in wetlands (34-66%probabiliry) <br />• facultative wetland species are wmmonly found in wetlands (67-99%probability) <br />• obligate species are alwavs found in wetlands under natural conditions, but may persist in non-wetlands iC planted or i(wetlands have been <br />transformed (>99%probabiliry) <br />Sections 16, 17, and 9 of Township 2 South, Range 67 West. <br />i9° 53' I ~" Latitude and 104° ~3'S0" Longitude, UTM (308i70ni~E. °a 1480pi'~N.). <br />
