Army Corps of <br /> Engineers regulates the discharge of dredged or till material.and any excavation associated with a <br /> dredged or till project,either temporary or permanent in waters of the United States(WOUS). WOUS <br /> may include ephemeral, intermittent and perennial streams.wetlands, lakes. ponds,drainage ditches and <br /> irrigation ditches. <br /> in order to determine if a discharge of till material would occur in a WOUS. we recommend a wetland <br /> delineations be conducted in the field by a qualified environmental consultant that identifies any aquatic <br /> resource boundaries. A wetlands delineation identities the aquatic resources and its boundaries on a <br /> project site and must be conducted using the methods outlined in the Corps 0/Engineers Wetlands <br /> Delineation Manual(Environmental I.aboratory 1987)and Regional Supplement to the Corps al <br /> Engineers Weilarul Delineation Manual: (using applicable Regional Supplement). Once the aquatic <br /> resources and its boundaries have been identified. the wetland delineation is not official unless verified <br /> by the Corps. Please note that the discharge of dredged or till material into upland areas or non- <br /> jurisdictional aquatic resources does not require authorization from this office. <br /> Nationwide Permits(NWP)authorize common types of till activities in WOt;S that will result in a <br /> minimal adverse effect to the environment. Descriptions of the 54 is pcs of nationwide permit activities <br /> and their general conditions can be found on our website: https: s,ss't.neo.usace.armv.milNissionsl <br /> Res;ulatory-Program'Colorado/.

An alternative analysis must be provided with this permit action. "I he alternative analysis <br /> must contain an evaluation of environmental impacts for a range of alternatives. Other action <br /> alternatives should include other practicable alternatives(with regards to cost, logistics. and technology) <br /> that meet the overall project purpose. The alternatives could include offsite alternatives and alternative <br /> designs. When evaluating individual permit applications,the Corps can only issue a permit for the least <br /> environmentally damaging practicable alternative 11.EDPA't.
