Project facilities are operated pursuant to Federal rights -of -way and annual operating plans (AOP) approved by the United States Forest Service (USFS). Homestake Reservoir on Homestake Creek in the White River National Forest (bordered by the Holy Cross Wilderness Area) stores water collected by Homestake primarily for trans - mountain use by the Cities of Aurora and Colorado Springs (the "Homestake Partners ") via the Homestake Tunnel. The northern portion of Homestake Reservoir, including Homestake Dam and outlet works, is located in Eagle County. The southern part of the Homestake Reservoir and the inlet to the Homestake Tunnel is located in Pitkin County. The general location of Homestake is shown on Figure 1. The Homestake Partners are undertaking the Homestake Dam and Reservoir Maintenance and Repair Project (Project) to comply with dam safety requirements of the Office of the State Engineer of Colorado. The existing upstream asphalt concrete facing of the dam has deteriorated as a result of ultraviolet light exposure, freeze -thaw damage, and severe surface erosion. The dam crest, the outlet works, and the Homestake Tunnel intake gate also require repairs. The maintenance required on the dam and outlet works will be conducted in Eagle County. The work associated with the Homestake Tunnel intake will occur in Pitkin County and is the focus of this submittal. This Project constitutes normal maintenance activities related to the safe operations of the dam and reservoir. The maintenance activities will not alter the operation of the existing dam and reservoir, and they will neither extend or enlarge the capacities of Homestake Reservoir or its related diversion facilities, nor change the amount or timing of water diversions. This report was prepared to provide information for the Location and Extent Review and Land Use Code Development Standards Review that Pitkin County has asserted are required for this Project. This report and the associated attachments provide supporting information to describe the proposed maintenance at the intake gate. This report is organized per the directions provided in the Pre - Application Conference Summary Sheet (Appendix I) Item 1. Additionally, Pitkin County requested that Homestake provide various items related to the Project for review, as summarized in the table below.

Homestake Reservoir and its tributaries do not flow into the Fryingpan River, or Ruedi Dam or 1-12--s" l-2 000JO8 SECTIONONE Location and Extent Review and Land Use Code Development Standards Review their watersheds. Furthermore, Homestake Reservoir is not listed or described in the Plan. As a result, it appears that Homestake Reservoir may not be covered under this Plan. However, at the request of the County, we have reviewed the compatibility of the planned repairs to the Homestake Tunnel gate to the Master Plan. Based upon this review, we have determined that the repair of the tunnel gate is consistent with the goals and objectives outlined in the Master Plan and in the Comprehensive Plan. The gate repair is consistent with the unifying concept in the Comprehensive Plan to "Preserve, Conserve and Protect the existing rural character of Pitkin County ". The gate repair is also consistent with the Master Plan as outlined below. Residential Growth. The repair is consistent with the goals of the Plan, in that it will not facilitate residential development within the upper Fryingpan River watershed, nor will it affect residential growth within the Eagle River watershed. Commercial Growth. The gate repair will not affect commercial development in the Fryingpan River watershed, nor in the Eagle River watershed. The gate repair will not affect agricultural lands, nor are any zoning changes applicable. Land Use and Environmental Considerations. The gate repair will preserve agricultural and recreation use. It will not affect water supplies in either the Fryingpan River watershed or the Eagle River watershed. The gate repair will not affect wildlife habitat, riparian and wetland areas, and other environmentally sensitive lands. The gate repair will not affect campgrounds, recreational sites or trail usage. Roads. The gate repair will not affect any county roads in Pitkin County, nor will any county roads in Pitkin County be utilized. Community Services. The gate repair will not affect law enforcement, emergency services, school buses, or noxious weeds and trash control. Historical and Cultural. The gate repair activates will not interfere with the preservation and protection of historical sites in the Fryingpan Valley, and will not affect historical sites in the Eagle River watershed. In summary, the proposed gate repair is associated with routine maintenance to promote human health and safety, and the operational reliability of the facility. Neither the operation of the tunnel, nor the existing reservoir footprint, will change with the gate repair. The gate repair is consistent with the Comprehensive Plan and the Fryingpan Master Plan. tm.P,aWg 241 H—I.a Pte,.

The current Homestake facilities were completed and began operations in the 1960s and all of the areas that would be affected by the maintenance Project have been previously disturbed and are currently occupied by the dam, reservoir, and ancillary facilities. Homestake Reservoir receives water from three sources: l) the main stem of Homestake Creek upstream of the reservoir; 2) Missouri, Fancy, French and Sopris Creeks via the Missouri Tunnel, which discharges into Homestake Reservoir at the left abutment of Homestake Dam; and 3) the East Fork of Homestake Creek delivered via a 60 -inch diameter welded steel inverted siphon pipeline terminating near the right abutment of Homestake Dam. Water diverted into Homestake Reservoir is delivered to the Homestake Partners via the Homestake Tunnel, which discharges to Lake Fork Creek leading to Turquoise Lake, Twin Lakes and to the Otero Pump Station and ultimately to the Partners' distribution systems. Water is released through the Homestake Dam outlet works, into Homestake Creek, a tributary to the Eagle River, at the toe of the dam. The Project involves maintenance repairs of several facilities including the dam, the outlet works, and the Homestake Tunnel intake gate. The rehabilitation of the Homestake Tunnel intake gate is the only activity that will occur in Pitkin County. The Homestake Tunnel, which delivers water to Turquoise Reservoir, is located approximately 4,000 upstream feet from the dam about half way up the reservoir on the south side. Water enters the tunnel through a reinforced concrete intake structure. During normal operations, the intake gate is held in the fully opened position with all releases controlled by valves located at the downstream end of the tunnel. The Project will remove and replace the existing cast iron guard gate and operating cylinder at the upstream end of the Homestake Tunnel. The existing gate opening in the intake structure will be partially excavated internally to accept a new gate thimble, and the new thimble will be grouted in place. A steel structure will be installed on top of the existing intake structure around the new operating cylinder to protect it from falling debris. In addition, new gate control equipment will be installed on a new concrete slab on the reservoir rim in the same location as the existing hydraulic controls. The new slab and controls will be enclosed in a new, lockable chain link fence. No changes to the Homestake Tunnel or the downstream discharge structure are included as part of this Project.

Project activities will be covered under the AOP administered by the USFS (Appendix H). Additionally, Homestake is responsible for consulting with federal, state, and county agencies for appropriate permits related to wetland impacts, sensitive species, cultural resources, and dam safety and operations. The contractor is responsible for permits related to stormwater management, air quality, earthmoving activities, and fuel storage. A summary of owner and contractor identified permits is summarized in Table 3.0 -1. The construction and future operation of the Project will be carried out in compliance with all applicable laws and regulations related to water resources, adjacent land uses, and wildlife. Biological field surveys were conducted to gather baseline environmental data in the Project area. Field work was performed under the guidance of the USFS, Colorado Parks and Wildlife (CPW) (formerly Colorado Division of Wildlife), and the U.S. Fish and Wildlife Service (USFWS) in the summer of 2010. Information obtained from the biological surveys was used as the basis for coordination with various agencies to verify permitting requirements. Biological, cultural, and wetlands surveys were conducted in July 2010 by URS and ERO to identify sensitive resources, and to obtain data for preparation of permits. In conjunction with the field surveys, URS reviewed available databases and publications and conducted informal consultation with biologists at White River National Forest, the USFWS, and the CPW to identify data requirements and procedures for compliance with Section 7 of the Endangered Species Act (ESA), the Migratory Bird Treaty Act, USFS sensitive species protection, State of Colorado coordination requirements, and fish salvage. Consultation was also conducted with the Corps of Engineers (USACE) for Section 404 permitting.

This work includes the following: improvement of existing access roads within the reservoir basin, construction of a low -head cofferdam, removal of the existing slide gate, installation of a new slide gate, installation of new gate controls and gate control lines, miscellaneous painting of components, and removal of the cofferdam. Construction is planned to occur between May and August of 2012. Due to the tight work area in the vicinity of the intake, staging of most equipment and storage of materials will occur outside of Pitkin County. Vehicles will access the Homestake Tunnel intake for task related work and will likely exit the area at the end of the day. Hours of work will likely be between lam and 7pm Monday through Saturday. 4.2 SEC. 7- 20 -10: SITE PREPARATION AND GRADING Site preparation and grading will consist of improvements to existing roads to access the Intake and the preparation and installation of a low -head cofferdam conveyance feature. All planned features are temporary and will be removed upon completion of the intake improvements. Please refer to Appendix A for detailed engineering drawings and specifications. 4.3 SEC. 7- 20 -20: STEEP AND POTENTIALLY UNSTABLE SLOPES The Homestake Tunnel intake is located at the toe of the reservoir rim slope. The existing controls are located on the reservoir bank directly above the intake. The slopes between the intake and the controls consist primarily of bedrock outcrops and shallow colluvial deposits. These slopes have been accessed during previous construction activities and no significant excavation activities are planned as part of this work. The Project Team does not expect to encounter unstable slopes in this area. 4.4 SEC. 7- 20 -30: WATER COURSES AND DRAINAGE Homestake Reservoir is located within the Eagle watershed (Hydrologic Unit Code 14010003), off of Homestake Road and is located within both Eagle and Pitkin Counties. The reservoir has a surface area of 335 acres and stores about 42,881 acre -feet of water at the spillway crest elevation of 10,266.5 feet. The original construction was completed in 1967. Homestake Reservoir receives water primarily from three sources: the main stem of Homestake Creek upstream of the reservoir, Missouri, Fancy, French, and Sopris Creeks via the Missouri Tunnel, and the East Fork of the Homestake Creek via the East Fork pipeline. Diversions occur primarily from the beginning of May through mid - August. The mean annual diversion rate for the Missouri Tunnel is 14.7 cubic feet per second (cfs), and for the East Fork pipeline is 5.5 cfs. Flows in Homestake Creek vary widely from year to year, with a peak mean daily flow of 135 cfs, and daily inflow in excess of 300 to 400 cfs for only a few days in the last 36 years. Inflow is generally below 50 cfs after August 1. UMN \Pqg t42 415%_HOmeAake_PMa Mub W120_Wad Pr \Pe MlnQPIbn Co \LO *n6en1_Reie PftW -Dwrwpew_For PnmmgW M912012259PM 4-1 ODUM9 SECTIONFOUR Compliance With Pitkin County Codes Water deliveries are generally made through the Homestake Tunnel, which leads to Turquoise Lake. Homestake Tunnel is 11.5 feet in diameter. Flow in the tunnel is controlled by a valve structure located at the downstream end of the tunnel. Releases from the reservoir are also made through the Homestake Dam outlet works at the toe of the dam, to Middle Fork of Homestake Creek. The daily outflow from the outlet works is generally less than 20 cfs, and there have been only 7 days in the last 36 years when the daily outflow exceeded 100 cfs. The Homestake Partners will not divert water through the Missouri Tunnel (Missouri, Sopris, Fancy and French Creeks) in 2012. Diversions from the East Fork will be limited to flows needed for construction only. Therefore, reservoir inflows will be limited to flows in the mainstem of Homestake Creek and areas directly adjacent to the reservoir. Water will be released from the reservoir through the Homestake Tunnel and through the dam outlet works. In 2013, reservoir storage from Homestake Creek, and diversions from the East Fork and the Missouri Tunnel will resume, although reservoir storage will be within a reduced elevation well below the crest of the dam. The overall volume of streamflow in Homestake Creek downstream of the Project will likely increase in 2012, as the only water diverted to Turquoise Reservoir will be natural inflow to the reservoir. During construction, the magnitude of peak stream flow in Homestake Creek will not likely exceed the peak stream flow that have historically occurred since the System has been in operation. This is because historical peak flows (recorded after construction of the System) have been similar to peak native stream flow that would have occurred if the Project had not been diverting water. In anticipation of the 2012 construction activities, Homestake Reservoir has been drained. Two cofferdams are planned to be constructed to control inflows to the reservoir, which are anticipated to peak around mid -June. The main cofferdam will be located in Eagle County about 200 feet upstream of the toe of the dam, at the location of a partially breached cofferdam previously used during the original dam construction. The cofferdam is anticipated to be constructed using fill material borrowed from the reservoir bottom and imported from offsite. A smaller low -head cofferdam will be located in Pitkin County at the Homestake Tunnel intake and will extend about 50 feet into the existing reservoir. The two cofferdams will serve to isolate the upstream face of the dam and the Homestake Tunnel intake from reservoir inflows. Inflows will be directed either through the Homestake Dam outlet works, or the Homestake Tunnel intake, as needed depending on reservoir inflows and schedule of work to facilitate construction activities. At the end of the 2012 construction season, the cofferdams will be breached and any imported materials will be removed and disposed offsite. Conceptual design for the coffer dams is provided in Appendix C. The construction should have no adverse effects to water quality. The contractor is required to implement water quality control measures during construction and has prepared a water quality control plan and stormwater management plan and obtained stormwater and water quality permits. The plan includes use of settling basins, filtration systems as needed, and regular monitoring. The primary containment will be effected by the cofferdam above the outlet works intake. Water contained between this cofferdam and the main dam will be controlled, monitored, treated and discharged into the active pool behind the cofferdam, and secondarily into the outlet works and from there to Homestake Creek.

Stockpile, laydown and disturbed areas will be silt fenced. Hay bale barriers and wattles will be used in highly erodible areas if they are identified. 4.5 SEC. 7- 20 -50: GEOLOGIC HAZARDS Homestake Dam is located on the Middle Fork of Homestake Creek, about 0.4 mile above the confluence with the East Fork of Homestake Creek. The dam and reservoir are in existence, and the footprint of the Project will be entirely within areas occupied by current facilities and areas disturbed during original construction of the original dam. Construction activities will not alter ecological units or landforms in the Project area. The Project is not anticipated to affect geology or geologic hazards, including avalanche, landslide, flood, settlement or siltation. Since construction will not occur in the winter, no avalanche control measures will be implemented. A summary of the regional site geology is provided below. The Project area is located in the glaciated valley of Middle Homestake Creek, surrounded by the Holy Cross Wilderness Area. Bedrock consists of Laramide intrusive rocks about 40-72 million years old, and Precambrian metamorphic rocks felsic and homblendic gneisses 1.7 -1.8 million years old, which are exposed on the ice - scoured walls of the valley and in some areas on the valley floor (Tweto 1979). Limited portions of the valley are occupied by glacial drift of the Pinedale and Bull Lake glaciations along with some modern alluvium. Elevations in the Project area range from about 10,000 to 10,300 feet, while the ridges above the valley reach 11,200 to 12,500 feet. Information on soils was obtained from the Holy Cross Area Soil Survey (USFS 1999). The predominant soils in the Project area are mapped as Man -Made Lands and Water. The dam, staging and laydown areas and portions of the access roads are mapped as Map Unit ML (man- made land). All of the construction areas within the reservoir including the coffer dams and water quality control features are in Map Unit W (Water). A portion of the access roads is in Map Unit 223B (Leighcan Family — Rock Outcrop — Cryoquolls complex, 0 to 40 % slopes). This map unit is about 40% Leighcan and similar soils, 30% rock outcrop, and 20 % cryoquolls and similar soils. Leighcan soils are occupied by lodgepole pine and spruce -fir forests, consist of very cobbly and stony coarse sand and sandy loam, and are somewhat excessively drained soils with an effective rooting depth of 20 to 40 inches. Cryoquolls are occupied by willow and sedge wetlands, consist of silt loams in the upper 15 inches, are very poorly drained, and have a seasonal water table within one foot of the surface and a depth greater than 60 inches. There are several avalanche chutes around the reservoir, including one at the left dam abutment. Trees and rocks deposited on the ice - covered reservoir in the winter are sometimes rafted to the dam and have to be removed. Homestake does not currently conduct any avalanche control activities either at the dam and reservoir or along the Homestake Road. There are no landslide areas in or near the Project area.

In addition, seasonal range for Bighorn sheep (Olds canadensis), mountain goat (Oreamnos americanus) and ptarmigan (Lagopus muta) is found on the ridge east of the reservoir, but not within the Project area. Relict beaver (Castor canadensis) dams were observed below the reservoir. Because all construction would occur in previously disturbed areas or in areas currently occupied by the dam, reservoir and roads, there will be no loss of forest habitat. The primary impacts to terrestrial wildlife may be temporary disturbance and displacement during construction as noise and human activity associated with construction may disturb or displace sensitive wildlife from forested and wetland habitats adjacent to the Project area. There is already regular human use of the Project area by recreationists that may result in some level of displacement or habituation. The existing dam and reservoir are a barrier to wildlife movement up the valley, and wildlife movement patterns will not change during construction. Although the area near the dam and access roads is used as habitat by several big game species, it is not considered sensitive for them. The dam is currently accessed during the winter by Homestake personnel using snowmobiles or snowcats on Homestake Road. This vehicle use, along with recreational snowmobiling, results in a packed surface that is used by wildlife for travel during the winter. During construction, Homestake Road will be plowed starting in March 2012 and April 2013. Wildlife are likely to continue to use the plowed road, but may be more vulnerable to harassment if plowing creates a canyon effect in some areas of deep snow that impairs escape off the road. CPW has expressed a concern that the plowed road might encourage early season use by members of the general public, and subsequent wildlife harassment or poaching. However, the USFS has approved the installation of a gate on FR 703 (also known as Homestake Road) to the east of Homestake Creek near Highway 24. The gate is expected to be installed in March 2012. Fish and aquatic habitat in the reservoir will be temporarily affected by drawdown of the reservoir and by changes in stream flows below the reservoir during construction. The reservoir has been drawn down beginning in late 2011 and will reach a minimum level in April 2012. A residual pool will be maintained because the reservoir basin (bottom) is deeper than the elevation of the outlet works and Homestake Tunnel. The reservoir will begin to be refilled November 2012, but will not reach normal levels until construction is completed in 2013. Preliminary discussions have been held with CPW regarding the potential for fish salvage from the reservoir. There are no formal requirements for fish salvage, and no permitting or plans needed, other than assistance to CPW in accessing the area during construction. CPW stopped stocking Homestake Reservoir in 2008 in anticipation of the maintenance work and drawdown. Since public access will not be allowed when the reservoir is drawn down, there will be no public salvage (suspension of normal bag limits), and any salvage will be performed by CPW.

In the unlikely event that clearing of riparian shrubs or cutting of trees is required for the Project, surveys or other mitigation will be required by USFS prior to construction activity. Potential methods include clearing of the construction area in advance of the breeding season to make the area unsuitable for nesting, timing of construction to avoid the breeding season, or use of pre - construction surveys to identify bird nests, combined with delays in construction for individual nests until the young birds have fledged and left the nest.

More information about this species is provided in the Biological Assessment/Biological Evaluation report (Appendix E). There is suitable habitat for greenback cutthroat trout in the Project area, but the Project area is outside of its known or suspected range. Four endangered fish species are found downstream of the Project area in the major tributaries of the Colorado River system, including bonytail, Colorado pikeminnow, humpback chub, or razorback sucker. Under the ESA, impacts to these four species need to be considered for projects that could result in new depletions (changes in amount or timing) to the Colorado River system. Because the Project does not new involve depletions, there will be no MN\Prgec 22415 Homa ake PM II\Sub_=12o_WO P= \Pei nng\Pabn COLOC n FiW ReieMPakrw De+ ew_For PnnLngOw NIW2012259PM 4-6 uuu'j24 SECTIONFOUR Compliance With Pitkin County Codes effect on these species. No federally listed, proposed, or candidate plant species have habitat in the Project area. The Project is anticipated to involve minor temporary impacts to lynx as construction activities may temporarily displace Canada lynx from the vicinity of the construction areas. There will be no permanent loss of habitat, and use and maintenance of the existing access roads will have no adverse effects. The Project would be in compliance with the objectives and guidelines of USFS management of lynx in the Southern Rockies. A Biological Assessment has been prepared for the Project and is provided in Appendix D. Other federally listed animal species, including greenback cutthroat trout, Mexican spotted owl, Uncompahgre fritillary butterfly, and yellow - billed cuckoo will not be affected by the Project. Colorado River fish living downstream of Homestake Reservoir will not be affected because the maintenance Project will not create new depletions. USFS Sensitive Animal Species The Project area includes sensitive habitat for a total of eight Region 2 sensitive animal species, including boreal toad (Anaxyrus boreas), northern goshawk (Accipiter gentilis), boreal owl (Aegolius funereus), olive -sided flycatcher (Contopus cooperi), Colorado River cutthroat trout (Oncorhynchus clarki pleuritucus), American marten (Martes ainericana), and pygmy shrew (Sorex hoyi). More information about these species is provided in the Biological Assessment/ Biological Evaluation report (Appendix E). One additional species, American three -toed woodpecker (Picoides dorsalis), was previously listed as a sensitive species and was on the list of species provided to URS by the Holy Cross Ranger District in 2010, but was removed from the 2011 sensitive species list (USFS 2011). Impacts to USFS sensitive species are addressed in the Biological Assessment/Biological Evaluation (Appendix E). The Project is expected to have no impact on boreal owl, wolverine, or American marten. The Project may cause minor short-term impacts to northern goshawk, olive -sided flycatcher, Colorado River cutthroat trout, boreal toad, and pygmy shrew. It is not likely to result in a loss of viability on the planning area for any of these species, or to cause a trend to federal listing or a loss of species viability range wide. USFS Sensitive Plant Species Special status species surveys were conducted in July 2010 using a list of species provided by Rick McNeill of the White River National Forest. Several of the target species were moonworts, and therefore all USFS sensitive moonworts that may occur in the central Rocky Mountains were surveyed (USFS 2011). Six species of moonworts were found, two of which, trianglelobe moonwort (Botrychium ascendens), and narrowleaf grapefern (Botrychhun lineari) are USFS sensitive species. No other sensitive plant species were found. A copy of the survey report is provided as Appendix C of the Biological Assessment/Biological Evaluation (Appendix E). The Project is expected to have no impact on triangleleaf moonwort and narrowleaf grapefern. The moonworts are located adjacent to the access roads and not within proposed construction areas. Impacts are being avoided by fencing the edges of the sites to prevent access or accidental impact during construction. MN\Prgec1a222415 H..Wake PM.

Homestake disclosed potential impacts to wetlands and waters of the U.S. in the Pre - Construction Notification (PCN) report contained in Appendix F. No wetlands in Pitkin County will be impacted. Wetlands surveys and delineations of the dam improvement footprint were conducted in July 2010. Sixteen wetlands totaling 1.4 acres were identified, most of which are located along the access roads (see Figure 2 in PCN, Appendix F). In addition, the Middle and East Forks of Homestake Creek (0.18 acre) were also delineated as other waters of the U.S. A maximum of 0.0005 acres (234 square feet), in seven wetlands (in Eagle County) may be permanently impacted by road improvements within the 16 -foot road corridor of each access road. The impact is minimal because the roads will not be widened. Construction activities will also affect about 15 acres within the basin of the existing reservoir, in areas that are normally inundated by water or that may be used as borrow areas. All of the impacts within the reservoir basin will be temporary. Additional information regarding impacts to wetlands and other waters can be found in the Clean Water Act Section 404 PCN (Appendix F). During construction, sediment fencing will be placed along the edges of wetlands and surface water bodies that are adjacent to the access roads and other construction areas to prevent degradation of water quality and to restrict vehicle movement into those areas. The primary pollutant that will be controlled will be sediment load and suspended solids. It is assumed that no chemical treatment will be required beyond clarifying and settling out suspended solids. � '.
