This arca is mapped as a movement corridor for black beats between sumller and fall coltcetltraliotr <br />ureas and (lie project site is within mapped fall concentration areas. Black bears concentrate in this area <br />during (lie fall, when they enter the physiological state of lyl)eg)hugim "Artificial food sources" or <br />foods made readily available by people such as garbage and food coolers, etc. attract black beats and <br />increase the potential for conflicts between bears and people. The CDOW encourages the project <br />developer to consult with the local wildlife manager to help address preventable conflicts and manage <br />onsite garbage storage. This area is also located in a natural corridor for mountain lions. <br />The La Plata River runs directly through portions of the project area and serves as suitable habitat for a <br />variety of fisli species strep as brook, brown, and rainbow trout and native mottled sculpin. Although no <br />threatened or endangered fish species arc present at the proposed project site, populations of rouluitail <br />chub, a State species of concerts, exist approximately 18 miles downstream of the site. The La Plata <br />River is also managed under a multi -State and multi -agency range -wide agreement for the conservation <br />of rotusdtail chub, bluellead and flannelmouth sucker. The La Plata River is a critical source of <br />Cr unaltered bluellead and flamsehnouth sticker. Critical habitat for Federally Endangered <br />Colorado pikeminnow and razorback sucker occurs at the La Plata -San Juan river confluence. These <br />populations of fish, both local and distant, may be affected by any changes in water duality as a result of <br />alining activity on the site. Compliance with existing state regulations regarding water quality standards, <br />sediment ranoff, bank stabilization, and chemical or waste water storage should be strictly enforced to <br />MUM existing fish populations are adequately protected. <br />The La Plata River on site and directly below the site sustains relatively low water flow during dry <br />summer months or during periods of drought. This increases fish species sensitivity to sedimentation <br />and contaminated runoff. Fxisting road maintenance and new road construction including temporary <br />stream crossings will likely be a primary sediment source. The CROW recommends tliat the applicant <br />design the project to minimize the total number of stream crossings. When it is necessary to cross <br />riparian areas and streams: <br />o Cotlstruct all stream and associated wetland crossings at tight angles to mininlize disturbance <br />o Control erosion and sedimentation front spoils and repair incised channels where excessive <br />erosion and sedimentation in occurring. <br />o Do not remove native riparian canopy or stream bank vegetation where possible; <br />a Avoid temporary ford crossings and utilize bridge crossings; <br />o Disinfect heavy equipment, hand tools, boots, and any other equipment that was previously used in a <br />river, stream, lake, pond, or wetland prior to moving equipment to another water body to avoid spreading <br />aquatic nuisance species or other tatdesirable biota (fish pathogens or parasites). <br />Thank you for the opportunity to cOnllllent 011 this proposal. ff you have any question or require <br />additional information, please contact District Wildlife tManager Trevor Balzer at (970) 375-6756. <br />Sincerely,, <br />Patt Dorsey <br />Area Wildlife ivlanager, Durango <br />xc: Geld Operations, Spezze, Area File, DWNI <br />
