The CWA also allowed the EPA to authorizethe NPDES Permit Program to State governments,enabling States to perform many of the permitting,administrative,and enforcement aspects of the NPDES Program (CWA section 402 Title 40 CFR at Part 123).For the State of Utah,the Utah Department of EnvironmentalQuality (UDEQ)issues the Utah Pollutant Discharge EliminationSystem (UPDES)Storm Water General Permit for ConstructionActivities (General Permit)No.UTR300000.This General Permit, as currently issued by the UDEQ,expires at midnight,June 13,2013 except as described in Part 2.4 of the permit.At that time,coverageunder a new or alternate permit may be required.A copy of General Permit can be found in AppendixA. General requirements of the General Permit includes submission of UPDES Notice of Intent (NOI); permitting fee;development,implementation,and maintenanceof a Stormwater Pollution Prevention Plan (SWPPP);and submission of Notice of Termination (NOT). Submission of the NOI and permitting fee must be made to the UDEQ Division of Water Quality prior to construction.Coveragestarts on the date the NOI is submitted.The fee is determined based on the length of time coverageis required.If a facility has the potential to discharge into a municipal separate storm sewer system (MS4),the MS4 may require a copy of the NOI.A MS4 is an organization of drainage basins,curbs,gutters,ditches,pipes,tunnels,or storm drains that discharges into waters of the United States.Coverageunder the General Permit ends uponsubmittal of the NOT. Once received,a copy of the NOI for the Sigurd to Red Butte 345 kV Transmission Line Project (Project) will be located in Appendix B -Notice of Intent of this SWPPP. A NOT form is located in AppendixC-Notice of Termination.The NOT for the GeneralPermit will not be submitted for the Project until final stabilization are measures,as defined in the General Permit and signed off on by Rocky Mountain Power.

Those sites identified within the Project POD as helicopter assist/low impact vehicle sites will be constructed using alternative construction methods.As such,work areas will be adjustedto meet the minimum work area needed to safely perform the work.After construction is complete,all temporary work sites and access roads will be re-contoured and reclaimed to the greatestextent possible. Structure locations,plannedwork site locations,and access roads are shown on the SWPPP Volume II Map Set l and POD Map Set 2. Post Construction Permanentaccess roads will be requiredfor long-term maintenanceactivities.Permanentaccess roads to be constructed or improved are shown on SWPPP Volume Il Map Set l and POD Map Set 2.These access roads will be constructedto PacifiCorp's Transmission ConstructionStandards to include those through steep terrain.Please referenceAppendixR-PacifiCorp's Transmission ConstructionStandards for more information. Where approved,a permanent work area at the base of each structure will be constructed for long-term O maintenanceactivities.The work area will be level with a slope no greater than 3 percent.Revegetation could occur in this work area and the area would be re-contouredto the greatestextent possible.The dimensions of this work area will vary by structure type but could be as large as the temporary work area used during construction. DrainagePatterns Drainage patterns within the Project area collect in severalarea creeks and follow site topographical patterns.Because of the semi-arid climate,most of the drainagechannels convey little or no stream flow for long periods of time during the year. Drainage along the flanks of the Pahvant Mountains collects in several area creeks,which generallyflow from south to north,and end up in the Sevier River.Along the eastern side of the PahvantMountains, drainagecollects in several area creeks that generallyrun from west to east.In other areas,the natural drainageis primarily overland runoff that generallyflows from west to east.Drainage within this basin region ultimately discharges into Sevier Lake. Vegetation Vegetation within the Project area has been consolidatedinto the following vegetation communities: Conifer/Woodlands(Zone 1),Shrub-lands (Zone 2),Grasslands (Zone 3),Wetlands/Riparianand Playa (Zone 4).Per the POD,the classification of vegetation communities in the Project area was based on geographicinformation system (GIS)data obtained from the Southwest Regional Gap Analysis Project (GAP).O Proprietary and Confidential ©2013 All rights reserved EC Source Services (ECS)SWPPP-19 Rocky ntgig P er ECS Project No.11-051 Exhibit No.3 Contract No.3000091215 Case 7PacifiCorpSigurd-Red Butte Witne IMitpA ail345kVTransmissionLineProject These vegetation communities are shown on SWPPP Volume Il POD Map Set 2 as Reclamation Zones 1 through 4.Please note that select areas of the Project have been impacted by wildfire.Wildfire impacted areas are identified on the SWPPP Volume Il POD Map Set 2 as Reclamation Subzone 1.

"Right-of-wayvegetation clearing:Vegetation clearing was estimated for the full area of the right-of- way and the area of tree clearing outside of the right-of-way associated with temporary and permanent access roads and other temporary and permanent Project facilities where vegetation communities within the right-of-way only.Calculations include vegetation types with the potential to grow 12 feet tall (aspen,mountain shrub,pinyon-juniper,and riparian)occur. 4A 5 percent contingency has been added to the total calculated acreage. The total estimated area of disturbance Project wide is 2,117.2 acres.Of this 1,608.8 acres is estimated to be temporary disturbanceand 508.4 acres is estimated to be permanent disturbance.The areas to be disturbed are described further below. Structure Work Sites A work area at the base of each structure is requiredfor construction activities.In order to providea safe working space,the work area must be level with a slope no greater than 3 percent.The dimensions of this work area will vary by structure type and onsite physical and environmental conditions.Typically, a temporary disturbancearea of approximately 150 feet x 200 feet (0.69 acres)is assumed for each non- O Proprietary and Confidential ©2013 All rights reserved EC Source Services (ECS)SWPPP-24 Rocky ng P er ECS Project No.11-051 Exhibit No.3 Contract No.3000091215 Case -7PacifiCorpSigurd-Red Butte Witne IMs&A ail345kVTransmissionLineProject lattice structure work area,and a temporary disturbancearea of 250 feet x 250 feet (1.43 acres)for each lattice structure work area. Within the vork areas described above,the permanent disturbanceassociated with the tower footings will be up to 40 square feet for H-framestructures,80 square feet for lattice deadendstructures,and 116 square feet for three-pole running angle structures. Wire Stringing Sites Wire string sites will typically be 150 feet x 750 feet for the Project.However,when construction occurs in steep and roughterrain,these sites raay require larger,less symmetrical areas.Disturbancehas been estimated at approximately 2.59 acres per site. Wire Splicing Locations During wire stringingoperations,splicing of the conductor wires will be necessary.This work often occurs mid-span between structures un ess site or environmental conditions warrant the use of implosive sieeves.Where wire splicing activities occur,additional access and worksites may be required. A temporary work area of approximateiy 100 feet x 100 feet (0.23 acres)is estimated for each wire splicing work area. GuardStructure WorkAreas Temporary guard structure work areas will typically be 75 feet x 150 feet in dimension,more when the transmission line meets the obstacle at an angle.Disturbance has oeen approximated at 0.26 acres per work area. Existing Access Roads Existing access roads will be utilized to the greatest extent possible during construction.A percentageof these roads do not require improvement,however,in some cases,repairs and/or improvements may be necessary to provide safe access for vehicles,equipment,and materials.More information on existing roads identified for Project use can be found in SWPPP Volume II Map Set l and POD Map Set 2. New Access Roads (Temporary and Permanent) In some areas,only temporary roads wl be needed.Typically,these temporary roads will be graded to a standard travel-surfacewidth of approximately 14 feet.In areas of steeper terrain,the travel-surface width could be a maximum of 22 feet for curves in the road,dependent on site-specific conditions. Normally,a ditch drainagesystem will not be constructedfor temporary roads.Temporary roads are shown on the SWPPP Volume Il Map Set l and POD Map Set 2 and will be reclaimed after construction. Permanentaccess roads will be constructedwhere needed for construction and/or long-term maintenance,or where landownersor land-managingagencies require road construction.Permanent roads will be graded to a travel-surfacewidth of approximately 14 feet.In areas of steeper terrain,the travel-surfacewidth could be a maximum of 22 feet for curves in the road,dependent on site-specificOProprietaryandConfidential ©2013 All rights reserved EC Source Services (ECS)SWPPP-25 Rocky nt4 P er ECS Project No.11-051 Exhibit No.3 ContractNo.3000091215 Case 7 PacifiCorpSigurd --Red Butte Witne IMe A ail 345kV TransmissionLine Project conditions.These access roads will be constructedto PacifiCorp's Transmission ConstructionStandards. Please referenceAppencúx R-PacifiCorp's Transmission ConstructionStandards for more information.In general,access roads follow the natural grade of area terrain with a typical slope of up to 10 percent. Turnout areas may be required along access roads so that vehicles and equipment may safely pass. Turnouts w I be approxiraately100 feet x 10 feet wide and will be located about every 1,000 feet along the road. Multi-Use Construction Yards /Support Facilities Multi-use construction yards and other support facilities will be located within proximity to the Project. This will include construction yards,helicopter support sites and staging areas.Activities within these areas may Mclude the fo owing:temporary batch plant locations;administrative offices;vehicle and equipment parking;fueling and maintenanceareas;and material storage.These facilities will range in size from aµproximately 5 to 20 acres per site. Additional ConstructionSite Estimates The calculated percentageof imperviousarea before construction is 0.43% The calcula ed runoff coefficient before construction is 0.07 The calculated percentageof imperviousarea after construction is 0.74% The calculated runoff coefficient after construction is 0.19 1.6 Water Resources As described within the POD,only low impacts on water resources will be anticipated in the northern Project area.The mitigadon of any high or moderate impacts can be attributed to spanning riparian areas or avoiding ground-disturbing activities that would remove soil-stabilizing vegetation in riparian areas such as at Dry Creek.Avoiding surface-disturbingactivities on steep slopes like those occurring in the Dry Hoilow area,where the potential for increased erosion following ground disturbance or removal of vegetation exists,also would reduce impacts. In the southern project area,the selected route is located within the Upper Virgin Watershed,which contains a state-listed impaired water (Santa Clara River)that has the potential for being affected by construction and maintenance activities.Ground disturbance related to the construction and maintenanceof the transmission line could potentially increase erosion in disturbed areas and reduce permeability of soils where compacted,potentially contributing to an increased level of total dissolved solids,salinity,chlorides,and selenium being discharged into the Santa Clara River.If not avoided or mitigated,this potentially could exceed effluent limits set by the EPA.However,with implementation of planned mitigation,most effects on state-listed impaired waters,as well as the municipal and agricultural needs of citizens livingdownstream,will be avoided and/or mitigated to acceptable levels.

Springs anc We/Is Six springs and twelve wdis have been identified within 600 feet of the Project ROW.Phillips 9-1Well and Utah State 31-33 Weil are approximately 300 feet from the centerline at Links 349 and 66, respectively.CalEnergy 28-3 Well is approximately 2,500 feet from the centerline at Link 75.Irvine Spring is approximately 13,000 feet from the centerline at Link 260.There are an additional three unnamedwells located at Links 365,386,and 430 and one unnamedspring at Link 444 within the Project ares.Springs and wells are also shown on the SWPPP Volume Il Map Set l and POD Map Set 2. Reservoirs,Lakes,and Ponds Duringthe FEIS process,several reservoirs,lakes,and ponds exist within the Project area.Large reservoirs in the Project area include Rock Ford Reservoir,Piute Reservoir,ThreeCreek Reservoir, Minersville Reservoir,Grass Valley Reservoir,and Newcastle Reservoir.Typically,natural lakes are found at higheresevation,where the cooler climate reduces the amount of water lost to evaporation and O snowmelt is retained in semi-impermeablebasins.Examples of natural lakes in the Project area include Duck Lake,Deep Lake,Hunts Lake,Barney Lake,Puffer Lake,Birch Lake,and Kent's Lake.Other man- mad lakes,ponds,and sroall reservoirsare found in the Project area,and are typically used for agricultural purposes.These include Taylor Pond,Moscow Reservoir,Sand Pond,Mound Pond,and Danish Reservoir. Impaired water bodies As previouslyreferenced,the Santa Clara River,a state-listed impairedwater,is located within the Project area.The Santa Cara River is Iccated approximately 1.7 miles southeast of the Red Butte Substation. Municipal Storm SewerSystems (MS4s) No known municipal Storm Sewer Systems (MS4s)occur along the Project. 1.7 Site Features and SensitiveAreas Uniquefeatures and sensitive areas within the Project will include soil resources,water resources, biological resources,naturalvegetation,wildlife species,and other environmentally sensitiveareas.
