7 APPENDIX A2 TRAFFIC AND TRANSPORTATION MANAGEMENT PLAN A2.1 Introduction This Traffic and Transportation Management Plan addresses regulatory compliance, traffic management practices, levels of right-of-way access, and mitigation measures to help reduce impacts related to transportation and the construction of temporary and long-term access for the Energy Gateway South Transmission Project (Project). A2.1.1 Plan Updates This plan will support the draft Plan of Development (POD) to a sufficient level to be able to execute the Bureau of Land Management (BLM) and U.S. Forest Service (USFS) Records of Decision. This plan will be updated and refined through the development of the POD to meet any stipulations of the Records of Decision, BLM right-of-way grant, USFS special-use authorization, and Bureau of Indian Affairs (BIA) encroachment permit and grant of easement before the issuance of the Notice(s) to Proceed and commencement of construction. The Company/Construction Contractor(s) will be responsible for any POD updates and refinements as well as implementation of the POD. A2.2 Purpose The purpose of this plan is to provide the BLM, the USFS, the BIA, other public agencies, the Compliance Inspection Contractor (CIC), and the Company/Construction Contractor(s) with a description of the type of access associated with the construction, operation, and maintenance of the Project. The goal of this plan is to mitigate traffic and transportation-related impacts from construction of the Project and associated access through mitigation measures and stipulations described throughout this plan. These mitigation measures and stipulations are intended to mitigate the effects of Project-related traffic and transportation on environmental resources, roads, travel, and road safety. A2.3 Regulatory A number of agencies have jurisdiction over the traffic and transportation-related components of the Project. At the federal level, these agencies include the BLM, USFS, Federal Highway Administration, Federal Railroad Administration, Federal Transit Administration, and the Federal Aviation Administration. At the state level, these agencies include the Wyoming, Colorado, and Utah Departments of Transportation; Wyoming Highway Patrol; Colorado State Patrol; and Utah Highway Patrol. At the local level, law enforcement and road departments are located in the cities/towns of Rawlins (Wyoming), Dinosaur (Colorado), and Nephi (Utah), and the counties of Carbon (Wyoming), Sweetwater (Wyoming), Moffat (Colorado), Rio Blanco (Colorado), Uintah (Utah), Duchesne (Utah), Wasatch (Utah), Utah (Utah), Sanpete (Utah), and Juab (Utah). All appropriate traffic and transportation permitting related to the construction of the Project is required to be identified and obtained by the Company/Construction Contractor(s) before the commencement of Project construction. In addition, the Company/ Construction Contractor(s) will coordinate relevant construction activities with applicable agencies and entities. Energy Gateway South Transmission Project A2-1 Plan of Development

8 A2.4 Traffic Management Practices Ground travel will be the primary means of transport in support of Project construction as well as Project operation and maintenance. All Project-related vehicles will obey jurisdictional traffic speed regulations and the posted speed limit. On roads where speed limits are not posted, the speed limit will be 15 miles per hour, unless otherwise directed by the CIC. Helicopter-assisted construction, as described in Section A3.6.2 Helicopter Use, could be used as deemed necessary and approved by the respective federal landmanagement agencies Authorized Officers or their designated representatives and in coordination with PacifiCorp (Company). Before construction, authorized access routes will be clearly marked in the field with signs or flagging (refer to Appendix A1 Flagging, Fencing, and Signage Plan). The Company/Construction Contractor(s) will review the location of proposed access and will be responsible for ensuring construction travel is limited to designated areas that clearly identify the limits of disturbance. Flagging will be maintained until final cleanup and/or reclamation is completed, after which they will be removed (refer to Appendix A1 Flagging, Fencing, and Signage Plan). All field personnel will attend an environmental training program (refer to Appendix A4 Environmental and Safety Training). Through this program, field personnel will be instructed to use only approved access roads, drive within the delineated road limits, and obey jurisdictional and posted speed limits to minimize potential impacts on environmental resources. The Construction Contractor(s), the CIC, and all environmental monitors will maintain a communications network that consists of one or both of the following devices: two-way radios or cellular phones. This will allow for coordination of equipment traffic along existing access roads so public safety, traffic impacts, and resource impacts are minimized. In general, the number of construction vehicles needed for the Project is not expected to substantially increase traffic volumes. Similarly, road and lane closures are anticipated to be minimal and most likely will occur during conductor stringing activities or during blasting. If road and lane closures are needed, the appropriate regulatory agencies, affected parties, and emergency service providers will be notified in advance by the Company/Construction Contractor(s). Project adjacent landowners will be notified of the construction schedule via hard copy letter sent by PacifiCorp, prior to the commencement of construction, although construction traffic is not expected to disrupt access to residences along the Project right-of-way. Signs will be posted in the Project area to notify landowners and others of the construction activity. Construction crews will park only in designated areas and will be shuttled to the appropriate work sites if necessary. A2.5 Types of Right-of-Way Access The Project right-of-way and other areas needed for construction will require access for Project construction, operation, and maintenance activities. Listed below are five types of access categories that will be used for the Project. The five types of access categories identified below are a sub-set that has been derived from the access levels in the Environmental Impact Statement (Levels 1 through 6) and provided in Table A3-2 Ground Disturbance/Access Levels (Appendix A3 Project Construction). The Table A3-2 access levels are derived primarily from slope conditions and proximity to existing access in the Project area. Refer to Table A3-2 for a correlation of each access level to the five access types described below. Energy Gateway South Transmission Project A2-2 Plan of Development

9 A2.5.1 Type 1: Existing Roads No Improvement This access road type includes paved or all-weather surfaced roads, including well traversed and established dirt roads that meet the Company s construction road standards. The Company s constructionroad standards include the use of a minimum travel surface width of 14 feet and require a travel-surface width of up to 22 feet depending on the radius of curves. The term No-Improvement is intended to signify that no new disturbance would be created outside of an established disturbed area. As such, the Existing Roads No Improvement access-road type could include regular maintenance to make the road passable for construction. Regular maintenance could include minor blading activities, repair of washed out areas, wash-boarded areas, depressions requiring graveling, approach installation, and other minor improvements. A2.5.2 Type 2: Existing Roads Improvements Required This access road type includes existing roads that require improvements to meet the Company s construction-road standards. The Existing Roads Improvements Required access-road type includes existing roads that may require widening to a minimum 14-foot travel-surface width to meet the Company s construction road standards. In areas of steep terrain, the road travel-surface width could be a maximum of 22 feet to meet the Company s construction-road standards, depending on the radius of curves and the slope of the terrain. As a result, total disturbance has the potential to exceed 22 feet, depending on the slope of the terrain. Disturbed areas, as a result of cut-and-fill slopes, would exceed the travel-surface width in areas of steep terrain. The area for tree clearing is not included in the maximum disturbance width. Improvements to this access-road type could include blading to create a road to meet the Company s construction-road standards, cut-and-fill activities, re-establishing drainage features, tree removal, boulder and rock removal, bridge and culvert construction, installation of wash crossings, and other improvements to provide an adequate surface to support construction and maintenance vehicles. Improvements to this access-road type may require reclamation to preconstruction conditions as determined by the land-management agency requirements or landowner requirements. A2.5.3 Type 3: New Roads Bladed This access-road type includes the construction of new permanent access roads where existing roads do not exist with the purpose of allowing for access to the Project right-of-way. New bladed access roads would be constructed to meet the Company s construction road standards. The Company s roadconstruction standards include constructing a minimum travel-surface width of 14 feet. In areas of steep terrain, the road travel-surface width could be a maximum of 22 feet to meet the Company s constructionroad standards, depending on radius of curves and the slope of the terrain. As a result, total disturbance has the potential to exceed 22 feet, depending on the slope of terrain. Disturbed areas, as a result of cutand-full slopes, would exceed the travel-surface width in areas of steep terrain. The area for tree clearing is not included in the maximum disturbance width. Stabilized construction entrances would be used to transition from paved surfaces to other access types. A2.5.4 Type 4: New Roads Overland Travel This access-road type includes new permanent access routes that would use overland travel with the purpose of allowing access to the Project right-of-way. It is intended that overland travel access is used in areas where access can be attained without construction of roads according to the Company s access road Energy Gateway South Transmission Project A2-3 Plan of Development

10 standards. As such, overland travel would be used in areas of relatively flat topography. The result would be an access route that would eventually become a two-track trail or naturally revegetate completely but still allow the Company s access without grading after construction. Overland travel comprises the following two different methods: Type 4a: Drive and Crush, is vehicular travel to access a site without significantly modifying the terrain. This access type would have a minimum 14-foot travel surface and disturbance width. Vegetation is crushed but not cropped; soil is compacted but no surface soil is removed. Even though vegetation may be damaged or destroyed, this creates vertical mulch on the surface soil and leaves the seed bank in place. Crushed vegetation would likely resprout after temporary use is stopped. A dozer, grader, or other type of equipment may be used to move boulders or other obstructions that prevent overland travel. Additionally, minor areas where the planned access crosses a side slope that exceeds the allowable slope for access by construction or maintenance vehicles may be graded to provide safe passage. The disturbed area would be blended, to the extent practicable, into the existing grades and revegetated according to the prescribed mitigations. Type 4b: Clear and Cut, is considered as above-grade removal of vegetation to improve or provide suitable access for equipment. This access type would have a minimum 14-foot travel surface and disturbance width. All vegetation is removed using above grade cutting methods that leave the root crown intact. The vegetation root ball would be left in place wherever practical to facilitate reestablishment. Soils are compacted, but no surface soil is removed. A dozer, grader, or other type of equipment may be used to move boulders or other obstructions that prevent overland travel. Additionally, minor areas where the planned access crosses a slide slope that exceeds the allowable slope for access by construction or maintenance vehicles may be graded to provide safe passage. The disturbed area would be blended, to the extent practicable, into the existing grades and revegetated according to the prescribed mitigations. The area for tree clearing outside of the travel surface is not included in the maximum disturbance width. A2.5.5 Type 5: Temporary Roads This access road type can include the temporary construction of new access roads, the use of existing trails/two track roads, or overland travel access to support the construction of the Project and access the Project right-of-way. This access road type does not require construction to meet the Company s roadconstruction standards. However, this access road type would be constructed to provide a safe travel way and, as such, temporary disturbance could result. Temporary disturbance would be dictated by the underlying ground conditions, but disturbance could range from significant, such as blading/cut and fill activities, to minor, such as overland travel. Unless otherwise noted by the land-management agency or landowner, this access-road type requires reclamation, to the extent practicable, to preconstruction conditions. Reclamation activities will be consistent with the requirements identified in Appendix C1 Reclamation, Revegetation, and Monitoring Plan Framework. A2.6 Mitigation Measures This section describes practices intended to mitigate potential environmental, traffic, and traffic safety-related impacts associated with access to and from the Project. The protection measures described below include design features of the Project for environmental protection (Section A2.6.1 Design Features of the Project for Environmental Protection) and selective mitigation measures (Section A2.6.2 Selective Mitigation Measures). Energy Gateway South Transmission Project A2-4 Plan of Development

11 A2.6.1 Design Features of the Project for Environmental Protection Following are design features for environmental protection to reduce potential impacts resulting from the transportation network for the project and the potential for increased levels of public access associated with the construction and operation of the Project. Design features for environmental protection are to be applied to all affected Project areas to help reduce potential access related impacts. Listed below are transportation-related design features for environmental protection to be implemented by the Company/Construction Contractor(s) during construction of the Project facilities: Design Feature 2. In construction areas where there is ground disturbance or where recontouring is required, surface reclamation will occur as required by the landowner or land-management agency. The method of reclamation normally will consist of, but not be limited to, returning disturbed areas to their natural contour, reseeding, installing cross drains for erosion control, placing water bars in the road, and filling ditches. All areas on lands administered by federal agencies disturbed as a part of the construction and/or maintenance of the Project will be seeded with a seed mixture appropriate for those areas. The federal land-management agency will approve a seed mixture that fits each range type. Seeding methods typically will include drill seeding, where practicable; however, the federal landmanagement agency may recommend broadcast seeding as an alternative method in some cases. A Reclamation, Revegetation, and Monitoring Plan Framework identifying reclamation stipulations will be developed and incorporated into the POD, which will be approved by the affected federal land-management agency prior to the issuance of a right-of-way grant (BLM), special-use authorization (USFS), encroachment permit and grant of easement (BIA), etc. Design Feature 3. Special-status species, threatened and endangered species, or other species of particular concern will be considered in accordance with management policies set forth by appropriate land-management or wildlife-management agencies. This will entail conducting surveys for plant and wildlife species of concern along the Project as agreed on by the agencies. Survey protocols must be accepted or recommended by the affected federal land-management agency, FWS, and state wildlife agencies, as appropriate. In cases for which such species are identified, appropriate action will be taken to avoid adverse impacts on the species and its habitat, which may include altering the placement of roads or towers, where practicable, as approved by the landowner and CIC, as well as monitoring activities. Design Feature 9. Based on preconstruction surveys and results of Section 7 consultation, state and federally designated sensitive plants, habitat, wetlands, riparian areas, springs, wells, water courses, or rare/slow regenerating vegetation communities will be flagged and structures will be placed to allow spanning of these features, where feasible, within the limits of standard structure design. Design Feature 10. In consultation with appropriate land-management agencies and the State Historic Preservation Officers and in accordance with the Programmatic Agreement (to comply with Section 106 of the National Historic Preservation Act) entered into among the BLM; the USFS; the BIA; the states of Wyoming, Colorado, and Utah; consulting parties; and tribes, specific mitigation measures for cultural resources will be developed and implemented to mitigate any identified adverse impacts. These may include Project modifications to avoid adverse impacts, cultural resources, monitoring of construction activities, and data recovery studies. Energy Gateway South Transmission Project A2-5 Plan of Development

12 Design Feature 14. A Fire Protection Plan will be developed and incorporated into the POD, which will be approved by the BLM, USFS, and BIA prior to the issuance of a right-of-way grant (BLM), special-use authorization (USFS), or encroachment permit and grant of easement (BIA). All internal and external combustion engines on federally managed lands will be operated per 36 Code of Federal Regulations , which requires all such engines to be equipped with a qualified spark arrester that is maintained and not modified. Design Feature 18. Grading will be minimized by driving overland in areas approved in advance by the land-management agency in predesignated work areas whenever possible. Design Feature 22. Fences, gates, and walls will be replaced, repaired, or reclaimed to their original condition or to current specifications as required by the landowner or the landmanagement agency in the event they are removed, damaged, or destroyed by construction activities. Fences will be braced before cutting. Temporary gates or enclosures will be installed only with the permission of the landowner or the land-management agency and will be removed/reclaimed following construction. Cattle guards or permanent access gates will be installed where new permanent access roads cut through fences on land administered by an affected federal agency or other grazing lands. Temporary gates across breached fences may be required when livestock are actively grazing an area in which the breached fence is located when construction activities have halted for a time. Should construction activities prevent use of a facility, such as a corral when that corral is needed to facilitate movement of livestock, then the Company will provide a temporary corral to facilitate movement of livestock. This temporary gate will prevent livestock on one side of the fence from going to the other side through the breach. Calving, lambing, and trailing areas will be avoided in the Project right-of-way and ancillary facilities. Calving season generally occurs between December and February but may vary from region to region. Lambing season generally occurs between March and June. Trailing areas (areas where livestock producers move livestock across lands to facilitate proper grazing management) can occur throughout the Project area and timing may vary throughout the year. Prior to construction, the Company will coordinate with the applicable land-management agency or private landowner to avoid areas used for calving, lambing, and trailing during construction. Design Feature 26. All vehicle movement outside the right-of-way will be restricted to predesignated access, contractor-acquired access, public roads, or overland travel approved in advance by the applicable land-management agency, unless authorized by the CIC (during construction). Design Feature 27. The spatial limits of construction activities, including vehicle movement, will be predetermined with activity restricted to and confined within those limits. No paint or permanent discoloring agents indicating survey or construction limits will be applied to rocks, vegetation, structures, fences, etc. Design Feature 32. If they are damaged or destroyed by construction and/or maintenance activities, watering facilities (tanks, natural springs and/or developed springs, water lines, wells, etc.) will be repaired or replaced to their predisturbed condition as required by the landowner or land-management agency. Should construction and/or maintenance activities prevent use of a watering facility while livestock are grazing in that area, then the Company will provide alternative sources of water and/or alternative sources of forage where water is available. Design Feature 36. Crossings of dry washes will be made during dry conditions, when possible. Repeated crossings will be limited to the extent possible but made at the same locations, if possible. Energy Gateway South Transmission Project A2-6 Plan of Development

13 Design Feature 37. If a riparian crossing were required during wet periods with saturated soil conditions, vehicles will not be allowed to travel when soils are moist enough for deep rutting (4 or more inches deep or a more stringent requirement as identified in individual resource management plans) to occur unless prefabricated equipment pads were installed over the saturated areas or other measures were implemented to prevent rutting. Equipment with lowground-pressure tires, wide tracks, or balloon tires will be used when possible. Design Feature 38. Canal and/or ditch crossings will require placement of temporary bridges or improvement of existing crossings. Design Feature 39. To minimize vehicle collisions with wildlife, a speed limit of 15 miles per hour will be employed on overland access routes. A2.6.2 Selective Mitigation Measures Selectively recommended mitigation measures to be applied on a site-specific basis to reduce access and transportation-related impacts include the following to be implemented by the Company/Construction Contractor(s) (refer to Volume II POD Map Sets): Selective Mitigation Measure 1 (Minimize/Avoid Disturbance to Sensitive Soils and Vegetation). In areas where soils and vegetation are particularly sensitive to disturbance, existing roads/two-tracks to be used for construction and maintenance will not be widened or otherwise upgraded to the extent practicable. To allow construction equipment access to work areas where the equipment will extend beyond the width of the existing roads, the construction equipment will straddle the road traveling on the road s shoulder only where terrain and soil conditions will allow for safe operation/transport of the equipment (cranes, cement trucks, etc.). Landmanagement agencies will work with the Company to determine the extent these existing roads can be modified versus fully upgraded to ensure the roads/two-tracks are passable and safe for the equipment and construction and maintenance personnel. Selective Mitigation Measure 2 (Sensitive Resources Avoidance). No blading of new access roads will occur in proximity to certain sensitive resources during Project construction or maintenance. Existing crossings and/ or overland access routes will be used for construction and maintenance in these areas. Methods such as matting can be used to stabilize access to work areas in these sensitive areas. To minimize ground disturbance, overland routes must be flagged with easily seen markers, and the route must be approved in advance. Selective Mitigation Measure 3 (Minimize Slope Cut and Fill). The alignment of any new access roads or cross-country routes in designated areas will follow the landform contours where practicable to minimize ground disturbance and/or reduce scarring (visual contrast) of the landscape, providing that such alignment does not impact other resource values. In addition to reducing ground disturbance associated with the construction of new access roads, modification to the size and/or configuration of the structure work areas facilitated by minor structure design adjustments will allow cut and fill slopes to be minimized and contoured to blend with existing topography to the extent practicable. Selective Mitigation Measure 5 (Minimize New or Improved Accessibility). To limit new or improved access into the Project area, as well as earthwork associated with the construction of tower pads in extremely steep terrain, all new or improved access and structure work areas not required for maintenance will be closed or rehabilitated using the most effective and least environmentally damaging methods appropriate to that area and developed through consultation with the landowner or land-management agency. Methods for road closure or management include installing and locking gates, obstructing the path, revegetating and mulching the surface of the roadbed to make it less apparent, restoring the road to its natural contour and vegetation, or Energy Gateway South Transmission Project A2-7 Plan of Development

14 constructing waterbars to ensure proper drainage. Tower pads will be contoured to blend with existing grade and revegetated to the extent practicable to reduce their visual dominance in steep terrain. Selective Mitigation Measure 10 (Helicopter-assisted Construction). Helicopter-assisted placement of towers during construction and helicopter patrol and maintenance may be used where practicable to reduce surface impacts in environmental constraint areas or steep terrain locations. Selective Mitigation Measure 12 (Seasonal and Spatial Plant and Wildlife Restrictions). To minimize disturbance to identified plant and wildlife species during sensitive periods, construction and maintenance activities will be restricted in designated areas unless exceptions are granted by the federal land-management agencies Authorized Officer or their designated representatives and other applicable regulatory agencies. A list of seasonal wildlife restrictions are presented in Appendix J, Table J-12, of the EIS. Selective Mitigation Measure 13 (Overland Access). The Construction Contractor will use overland access to the greatest extent possible in areas where no grading will be needed to access work areas. Overland access will consist of drive-and-crush and/or clear-and-cut travel (removal of all vegetation while leaving the root crown intact to improve or provide suitable access for equipment). Prior to commencement of work activities, overland access routes will be staked to a minimum width of 14 feet. Routes will be specified in the POD. Use of overland access routes will be restricted based on dry or frozen soil conditions, seasonal weather conditions, and relatively flat terrain. Selective Mitigation Measure 15 (Limit Accessibility in Sensitive Habitats). Where feasible, access roads that traverse sensitive habitats will be gated or otherwise blocked in cooperation with the appropriate land-management agencies to limit public access. Selective Mitigation Measure 16 (Blend Road Cuts or Grading). Soil amendments, mineral emulsions, or asphalt emulsions will be applied, or grading techniques such as slope rounding and slope scarification will be used, to blend road and structure work area cuts into the landscape in areas of steep terrain where grading is necessary, in rocky areas, or where soil color would create strong landscape contrasts. A2.6.3 TR 1 TR 2 Other Specific Stipulations and Methods A Traffic and Transportation Management Plan will be developed and implemented by the Company/Construction Contractor(s) to provide site-specific details showing how the Project will comply with the other specific stipulations and methods listed in this appendix. This plan will be submitted to and approved by the appropriate federal, state, and local agencies with authority to regulate use of public roads and approved prior to the issuance of a Notice to Proceed with construction. Dust suppression techniques will be applied, such as watering at least twice daily in all disturbed areas undergoing active construction or disturbance and watering all unpaved roads at least twice daily in areas of active use. Dust suppressants, if warranted, will be applied to unpaved roads and other disturbed areas. Speeds on unpaved roads will be limited to 15 miles per hour. Tracked-out dirt where unpaved roads or disturbed areas meet paved roads will be swept every 14 days, using PM 10 efficient street sweepers, in areas of active construction or use. These actions will help to prevent powdering of soils on roads, maintain firm working surfaces, limit fugitive dust, protect topsoil for reclamation, and prevent safety Energy Gateway South Transmission Project A2-8 Plan of Development

15 TR 3 TR 4 TR 5 TR 6 TR 7 TR 8 TR 9 TR 10 TR 11 TR 12 TR 13 TR 14 TR 15 hazards or nuisances on access roads and in construction zones near residential and commercial areas and along major highways and interstates. If the Project proposes to obtain water to suppress dust, the required water will be procured from municipal sources and/or from landowners or other previously allocated sources. Water shall not be procured from streams or lakes or other natural waterways. All procured water will require written approval, which will include how much water will be used as well as a map and shapefile showing the location of the procurement site. This written approval must be provided to the CIC and the Company prior to procuring the water. No new water rights will be required. If a construction method requires the closure of a state- or county-maintained road for more than 1 hour, a plan will be developed to accommodate traffic as required by a county or state permit. On county- and state-maintained roads, caution signs will be posted on roads, where appropriate, to alert motorists of construction and warn them of slow traffic. Traffic control measures, such as traffic control personnel, warning signs, lights, and barriers, will be used during construction to ensure safety and to minimize traffic congestion. To reduce traffic congestion and roadside parking hazards, an equipment yard will be provided for primary parking for employee personal vehicles. Unauthorized vehicles will not be allowed in the construction right-of-way or along roadsides near the right-of-way. Construction vehicles will follow a speed limit of 15 miles per hour on unposted Project roads. All temporary culverts and associated fill material will be removed from stream crossings after construction. Landowners will be notified at least 48 hours prior to the start of construction within 0.25 mile of a residence. Emergency vehicle access to private property will be maintained. Roads in residential areas will be reclaimed as soon as possible, and construction areas near residences will be fenced off at the end of the construction day. Existing roads will be returned to preconstruction condition. The Construction Contractor(s) will be responsible to document preconstruction conditions prior to the commencement of existing road use. Roads identified as temporary will be reclaimed as specified in the Reclamation, Revegetation, and Monitoring Plan Framework (Appendix C1). Signs will be posted by the Construction Contractor(s) on all temporary roads and overland access routes identifying them as reclamation areas. Signs will state Restoration in Progress No Vehicle Traffic Allowed. Existing roads in the right-of-way corridor will be used to the maximum extent possible for construction, operation, and maintenance activities. Energy Gateway South Transmission Project A2-9 Plan of Development

16 TR 16 Crane mats, geotextiles with gravel, and/or rock would be used to access wet or wetland areas. Mats would be placed directly on vegetation. Within 30 days of the completion of the construction and/or maintenance activity, the mats, geotextile with gravel, and/or rock would be removed, allowing the vegetation to naturally reestablish.
