1 <br /> <br />f <br />1 <br />BULL SEEP -CAMAS WEIl-AND DELMEATION REPORT <br />APPENDIX <br />JURISDICTIONAL REQUIREMENTS <br />Section 404 of the Clean Water Act of 1977, revised 1992, states that a permit may be needed for the discharge of dredged or fill material into <br />Waters of the US, including wctlands. <br />WcUand dclincation sNdies are required by the Act in order to detcnnine potential cftecrs o(drcdge or fill activities in navigable waters, waters <br />of the United Stares or wetlands. Dredge material is maz which is expvated or dredged from wazcr and wetlands. Fill material is that which is <br />used for Ne primary purpose of replacing an area of a water body with dry land or for changing the bonom elevation of a water body. <br />Thc result of this Act concerning Waters of the US is that at any time mareriaz is to be put into or taken from a stream or adjacent wetlands; <br />compliance with the Ac[ must be achieved. The principal responsibility for rcgulazing the Clean Water Act Ties with the US Army Corps of <br />Engineers. Other agencies with which penni[Ung must be coordinazed include the US Environmental Protettion Agency, the US Fish and <br />Wildlife Service, and state agencies including agencies conamed with wildlife and water quality. , <br />METHODOLOGY <br />A. Inventory, Mapping and Sampling <br />Potential wetland areas m be sNdied were determined from a comprehensive level survey of wetlands bated on vegetation and soil sampling. All <br />potential arcaz were cxamincd using the thee-parameter approach for hydric chamctcristics described below. Wetlands previously delineazcd <br />were verified during the field investigations. Maps oCweUands occurring 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 chamc[erized using the guidelines <br />described in: Department of the Army, Waterways Experiment Station, Corps ofEngineers - Corps of Engineers Wetlands Dclineazion Manual <br />(Depernncnt of Ute Army, 1987). These guidclincs are used to determine wetlands on the basis of interrelated analyses of vege[aion, soils, and <br />hydrology described below. A given area must contain evidence of each of the three indicators to be considered ajutisdictional wetland. <br />Diagnostic characteristics used in identifying wetlands that oc~vr in the project area foreach of the three factors in the mul ti-parameter analysis <br />arc as follows: <br />1. Ve¢eta[ion: The predominance of plant species that arc typically adapted to life within habitats that have permanent or alternating dry and <br />inundated and/or saturated soil conditions. The following classificazions of plants as indicators of wetland ornon-wetland conditions apply to <br />this criterion (Reed, 1988): <br />• upland specie are almost always found in uplands (>99°/ probability) <br />• facultative upland species arc commonly found in uplands, but may occur in wetlands (1- 33%pmbability) <br />• facultative species may or may not occur in wetlands (34-66% probability) <br />• facultative wetland specie are wmmonly found in wetlands (67-99°,e probability) <br />• obligate species are always found in wetlands under natural conditions, but may persist innon-wetlands if planted or if wetlands have been <br />transformed (>99%pmbability) <br />Sections 16, 17, and 9 of "Cownship 2 South, Range 67 West. <br />39° 53' 15" Latirude and 104° 53'50" Longitude, UTM (30830ni E.
