Central Ferry-Lower Monumental 500-kilovolt Transmission Line Project

Proposed Action

BPA is proposing to construct, operate, and maintain a 38- to 40-mile-long 500-kilovolt (kV) transmission line in Garfield, Columbia, and Walla Walla counties, Washington. The proposed line would extend west from BPA’s planned Central Ferry Substation in Garfield County to BPA’s Lower Monumental Substation located in Walla Walla County. BPA is considering four routing alternatives for the proposed Central Ferry-Lower Monumental transmission line; portions of all four routes would parallel existing BPA lines in the area. Two of the routing alternatives for the transmission line are about 38 miles long, and the other two are about 40 miles long.

Conditions of Approval

BPA is responsible for implementation of mitigation measures during development of the project. A Mitigation Action Plan (MAP) was prepared as part of the Finding of No Significant Impact (FONSI). All the mitigation measures described in the Draft EIS and updated in the Final EIS have been adopted. The MAP is available for download at: http://efw.bpa.gov/environmental_services/Document_Library/Central_Ferry-Lower_Monumental/CentralFerry-LowerMonumental_ROD.pdf

Close• Prior to construction, conduct a detailed geologic hazard assessment for the selected action alternative. This assessment will include a review of geologic maps and aerial photomaps combined with surface condition assessments at each proposed tower location and surrounding terrain. In addition, subsurface information will be obtained from water well logs, material exposed in existing road and stream-cut slopes, and construction/design information from the existing transmission lines in the project area. Particular attention will be given to on-site evaluation of the slope stability of each proposed tower location. Tower or road locations found to be within previously unidentified active slides, bedrock hollows, or other geologic hazard areas will be relocated outside the limits of these areas.

• Prepare and implement a Stormwater Pollution Prevention Plan (SWPPP) to lessen soil erosion and improve water quality of stormwater run-off. SWPPPs are developed to prevent movement of sediment off-site to adjacent water bodies during short term or temporary soil disturbance at construction sites. The SWPPP for this project will address stabilization practices, structural practices, and stormwater management. Design access roads to control runoff and prevent erosion by using low grades, outsloping, intercepting dips, water bars, or ditch-outs, or a combination of these methods.

• Minimize construction equipment use within 150 feet of a water body (stream or river).

• Surface all permanent access roads with rock to help prevent erosion and rutting of road surfaces and to support vehicle traffic.

• Minimize construction on steep, unstable slopes, if possible.

• Save topsoil removed for structure and new access road construction for onsite restoration activities to promote regrowth from the native seed bank in the topsoil. If contaminated, follow-up weed control will be needed.

• Cover exposed piles of soil with plastic or similar material to reduce erosion potential from rain or wind.

• Cut or crush vegetation, rather than blade, in areas that will remain vegetated in order to maximize the ability of plant roots to keep soil intact and prevent sediment movement offsite. • Revegetate or reseed all disturbed areas with a native plant/grass seed mixture, suited to the site and landowner, to promote vegetation that will hold soil in place.

• Till or scarify compacted soils before reseeding where necessary.

• Monitor erosion control Best Management Practices (BMPs) to ensure proper function and nominal erosion levels.

• Monitor revegetation and site restoration work for adequate growth; implement contingency measures as necessary.

• Mark construction limits within agricultural fields or grasslands to minimize disturbance. • Inspect and maintain project facilities, including the access roads.

• Inspect and maintain tanks and equipment containing oil, fuel, or chemicals for drips or leaks and to prevent spills onto the ground or into state waters.

• Maintain and repair all equipment and vehicles on impervious surfaces away from all sources of surface water.

• Refuel and maintain equipment at least 25 feet from any natural or manmade drainage conveyance including streams, wetlands, ditches, catch basins, ponds, and pipes, and provide spill containment and cleanup. Utilize pumps, funnels, and absorbent pads for all equipment fueling and maintenance operations.

• Provide spill prevention kits at designated locations on the project site and at the hazardous material storage areas.

• Minimize the number of road stream crossings.

• Stabilize cut and fill slopes.

• Use a seed mix approved by the local Farm Service Agency to re-vegetate areas of Conservation Reserve Program land that are disturbed during construction activities.

• Noxious Weeds

  o  Comply with all federal noxious weed control regulations and guidelines, and comply with     state and county noxious weed control regulations and guidelines to the extent practicable.
  o  Wash all equipment using pressure or steam before entering the project area and when leaving discrete patches of noxious weeds.
  o  Map and flag noxious weed populations for construction crews so these populations can be avoided when possible. Clean vehicles after leaving these areas to avoid the spread of noxious weeds.

o Cooperate with private, county, state, and federal landowners to treat noxious weeds along access roads that will be used to bring construction equipment into the project area to reduce the introduction and spread of noxious weeds and noxious weed seeds.
Close• Implement the Memorandum of Agreement (MOA) with WDNR that reduces noxious, invasive and undesirable species including tall growing woody plants and works towards compatible and native low growing species vegetation on WDNR lands. The MOA also will provide coordination between WDNR and BPA for the use of herbicides on lands where WDNR uses herbicides and minimizes the use of herbicides on lands where WDNR does not use herbicides.

• For any noxious weed management plans prepared for proposed weed control and other vegetation maintenance on WDNR managed trust lands as part of future line maintenance activities, coordinate preparation of these management plans with WDNR staff.

• Commit to coordinating with WDNR regarding the 1989 DNR Agricultural and Grazing Lands Policy Plan, Agriculture Business Plan, Strategic Plan, and related Resource Management Plans for affected WDNR parcels during construction and maintenance of the line and access roads over WDNR trust lands. Provide WDNR with notice of potential impacts to affected lands enrolled in the Conservation Reserve Program. Request permission to disturb ground cover as needed to complete the project and agree to restore impacted lands outside of lands developed to tower pads and access roads to the same type of cover at no expense to any applicable WDNR lessee or to WDNR as landowner.

The agreement could address various provisions related to unauthorized access, such as additional measures to be taken to discourage unauthorized use of the project corridor and associated access roads, periodic inspection for unauthorized access and any resulting damage, and repair of any damage from unauthorized access.

• Install marker balls on the conductor and lights on towers at the Tucannon River crossing if required by the FAA.
