The Pacific Connector pipeline’s Coos Bay Water Route requires the construction right-oto be between 225 and 300 feet in width and TEWAs to be located in the bay. The construction right-of-way and location of the TEWAs have been designed to encompass areas that may be affected by pipeline activities during construction. These activities inctrench excavation, pipe laying from a barge, trench backfilling activities, and temporary scontainment. These workspace requirements are based on bed material/sediment characteristics, the benthic topography, current velocities and other factors that could 

potentially affect the footprint of the project disturbance. The Coos Bay Water Route 

Construction Plan (see Appendix 2J to Resource Report 2 of Pacific Connectors applicawith the FERC) details the rationale/necessity for the construction right-of-way width and TEWAs. The construction plans provide the BMPs that would be used to minimize adveimpacts from in-water activities.

Agricultural Wetland - Disturbed Emergent Pasture: The alignment across the Kentuck Slough floodplain crosses approximately 500 feet of

The crossing of Kentuck Slough is proposed as a bore whirequires TEWAs 6.17-N, 6.23-W, 6.20, 6.29-N, 6.29-W and 6.31 for installation of bore pdewatering areas, storage of topsoil and spoil materials and installation of the pipeline athe floodplain by conventional methods. The construction right-of-way across the floodpalso 95 feet in width and cannot be narrowed. The right-of-way width cannot be narrowed and the TEWAs cannot be eliminated within 

wetland pastures because the trench width may become excessively wide due to the higgroundwater table and the unconsolidated and saturated soils in the wetland. The right-width and TEWAs are necessary because the trench would be wider in the wetland due concrete coating of the pipeline. The pipeline would be coated with several inches of coto compensate for pipeline buoyancy which increases the overall pipe diameter. The pip

in the pasture would have 5 feet of cover compared to the standard 3 feet of cover in no

agricultural uplands. It would be difficult to contain/confine saturated trench spoil materiwithin the wetland because these materials typically lack sufficient strength for staking othese materials.

The construction right-of-way cannot be narrowed because the trench width may become excessively wide within these emergenwetlands/pasture. This is due to the high groundwater table and unconsolidated and sasoils in the wetland.

This increases the overall pipe diameter. The burial depth of the pipelinthe pasture would have 5 feet of cover over the top of the pipe compared to the standard feet of cover in non-agricultural uplands. It may be difficult to contain/confine the saturatrench spoil materials because these materials typically spread out when staked due to insufficient strength.

Based on previous survey work, photo interpretation and review existing data (NWI and soil surveys), an emergent wetland is suspected in this pasture a15.74. TEWAs 15.72-W and 15.72-N were located in the level wetland pasture because critical staging needs in this area. Existing access is available at this location and the piroute is remote and rugged both to the north and south. To minimize impacts to this wepasture, Pacific Connector proposes to use the area primarily in the dry season; topsoil be salvaged from the entire TEWAs; and the area would be scarified (ripped) during restoration, and revegetated according to its ECRP.

These TEWAs are required for the diverted open-cut crossing of the South Umpqua RivAlthough these TEWAs appear extensive, disturbances within these designated work ar

would primarily be confined to the right-of-way centered along the pipeline during trench

operations. The proposed trenching activities would occur in the “dry” by installing temporary/portable diversion structures (dams) to divert flow from one side of the existin

gravel bar to the other through the existing channels on either side of the gravel bar. Th

purpose of the large size of the TEWAs is to provide sufficient areas on either end of the 

existing gravel bar (upstream/downstream) to provide the necessary access to install the 

appropriate temporary diversion structures at the correct location so that trenching activ

can be accomplished in the dry. Because gravel bars typically reconfigure annually withriverine systems during high flows periods, the exact placement of the temporary in-strediversion structures is not currently known. Therefore, a large area is shown primarily focontingency purposes.

Agricultural Wetland – Hayfield/Pastures: The construction right-of-way and TEWA requirements in this hayfield/pasture wetland was designed in consideration of the railrocrossing, the two sharp pipeline bends in the alignment and the required 5 feet of cover the pipeline. The railroad would be bored and because of the length of the wetland the pits could not be placed outside the wetland. The two pipeline bends would require addworkspace to install the radius bend or fitting and to contain the associated additional spmaterials. Because of the location of the bends the TEWAs could not be placed outside wetland. In this area, the trench width may become excessively wide due to the high groundwater table and the unconsolidated and saturated soils in the wetland. Therefore full 95-foot construction right-of-way was maintained through these wetland pastures. Tright-of-way width and TEWAs are necessary because the trench would be wider in the wetland because the pipeline would be weight-coated with several inches of concrete to compensate for pipeline buoyancy which increases the overall pipe diameter. Further, texcavated trench spoil material would be difficult to contain/confine because they are expected to be saturated and would be spread out when stacked.

Pacific Connector’s Project-Wide Requests for Modifications to the FERC’s Wetland and Waterbody Constru

Procedures

Location or Activity Requested Modification and Rationale 

Various Uncleared Storage Areas (UCSA) near Waterbodies and Wetlands 

Pacific Connector requests a modification for the location of the UCSAs to be allowed within 50 feet of wetlands or waterbodies so that large woody debris can be stored on site and in close proximity to where it would be redistributed during restoration. UCSAs would be used to store forest slash, stumps, and dead and downed log materials that would be scattered across the right-of-way after 

construction. Pacific Connector requests this modification because forest and vegetation clearing would not occur in these areas, therefore the potential for sedimentation to a wetland or waterbody is greatly minimized. Other than large woody debris, woody material generally less than 8 inches in 

diameter would not be stored in the UCSAs within 50 feet of a wetland or waterbody. 

Ac

Various ditches and intermittent streams not flowing at the time of construction 

The project crosses numerous road ditches and intermittent streams that are not expected to be flowing at the time of construction. As defined by Section I. B.1. of FERC’s Procedures, these features are not considered waterbodies and are therefore protected under FERC’s Plan. Pacific Connector would comply with this definition, except for intermittent streams on federal lands covered 

under the Northwest Forest Plan. Pacific Connector has generally provided minimum setbacks from 

these types of features and the TEWAs have been located outside these features where practical 

CoPr

Agricultural irrigation canals and ditches, especially in Klamath Basin between MPs 192 - 231 

A significant number of agricultural ditches and canals are traversed by the project in the Klamath Basin within agricultural croplands, pastures, and hayfields. These canals and ditches do not support riparian vegetation and adjacent areas are disturbed emergent and actively cultivated hayfields and pastures. Therefore, consistent with FERC’s Wetland and Waterbody Procedures (Section V. B. 2. a.), the locations of TEWAs have been located immediately adjacent to these waterbodies without a 50-foot setback to facilitate these crossings. 

CoPr

Vehicle and Equipment Refueling/Parking 

Pacific Connector and their contractors would attempt to park all equipment overnight and fuel equipment at least 100 feet from waterbodies or in upland areas at least 100 feet from wetland boundaries. These activities would only occur closer if the Environmental Inspector finds, in advance, 

no reasonable alternative and the contractors have taken appropriate steps (including secondary containment structures) to prevent spills and provide for prompt cleanup in the event of a spill and the 

procedures outlined in Pacific Connector’s SPCC plan is followed. 

AcCoadme

Waterbodies containing coldwater fisheries 

According to Section V.C.1. of FERC’s Procedures, clean gravel or native cobbles for the upper 1 foot of trench backfill is required in all waterbodies that contain coldwater fisheries, regardless of stream substrate materials. Pacific Connector requests a modification for fish bearing streams that do not have gravel, cobble or other existing rock substrates. Many of these streams crossed by the project are remote and steep valley or ravine bottoms therefore hauling rock to these steams would create 

more disturbance and is impractical, especially where these streams do not have these substrate 

characteristics. Pacific Connector would backfill with native stream bed material in these instances.

Pacific Connector’s Requests for Modifications to the FERC Staffs Upland Erosion Control, Revegetation and 

Location or 

Activity Requested Modification and Rationale 

Treatment of Forest Slash 

Treatment of Forest Slash and Modification From Section IV.F.3.e of FERC’s Plan 

Slash from timber clearing would be salvaged on or at the edge of the right-of-way and scattered/redistributed across the right-of-way during final cleanup and reclamation according to BLM and USFS fuel loading specifications to minimize fire hazard risks. This material would be pulled back onto the right-of-way during final cleanup after seeding. If during final redistribution significant disturbance occurs to seeded areas the EIs would ensure that supplemental hand broadcast seeding occurs to ensure adequate seed coverage for erosion control. Where it is not feasible to pull the slash back onto the right-of-way after seeding, seeding in these areas (broadcast or hydro seeding) would occur with specifications to ensure adequate seed coverage. Scattering the slash across the right-of-way would hinder Off Road Vehicle (ORV) traffic on the right-of-way and would act as a natural mulch to minimize erosion. Because more than 1 ton per acre of woody material (logs, slash and chips) may be scattered across the right-of-way during final cleanup in many areas, Pacific Connector requests a modification from Section IV.F.3.e. of FERC’s Plan. Pacific Connector would utilize the fuel loading standards of the BLM and the 

USFS as the limit for the quantity of woody debris that would be distributed across the right-of-way to minimize fire hazard risks for this modification request. Section IV.F.3.e of FERC’s Plan states that if wood chips are used as mulch to not use more than 1 ton per acre of chips and to add an equivalent of 11 lbs of available nitrogen where chips are used as mulch. The purpose of Section IV.F.3.e. of FERC’s Plan is to ensure that revegetation efforts are not hindered due to the decaying process of large amounts of wood chips which can bind-up soil nitrogen and impede revegetation. Pacific Connector requests this modification because it would be impractical and infeasible to remove this material from the right-of-way and it is a typical silvicultural practice in the project area (i.e., forest slash left in logged areas). It is expected that the woody slash material would not deplete soil nitrogen in the short-term, during revegetation establishment, because the size of the woody material that would be scattered on the right-of-way would be large and would not 

readily decay in the short-term. 

Topsoil salvaging on forest lands where requested by landowner 

Along the alignment where topsoil segregation is proposed, Pacific Connector has requested 10 feet of 

temporary extra work area in addition to the 95-foot construction right-of-way to effectively conduct topsoil 

salvaging on level terrain. The purpose of this temporary extra work area is to ensure that the topsoil is 

segregated and kept separate from the trench subsoil. In steep forested landscapes, it is impractical to 

salvage topsoil based on topographic and vegetation conditions (i.e., large trees/stumps that would have to be removed in order to accomplish the task). The USFS has requested that topsoil be salvaged on USFS lands. However, Pacific Connector is requesting a modification from Section IV.B.1 (4) of FERC’s Plan which specifies that topsoil be salvaged according to landowner requests. Pacific Connector requests this modification on all forest lands managed by the USFS, BLM, or private landowners. The purpose of the modification is to prevent the need for additional temporary extra work areas (and associated disturbance) on 

USFS lands to conduct the topsoil segregation. The proposed pipeline mainly traverses forested habitats through USFS lands which are primarily designated as LSR. 
Appendix I –

Modifications to 

I-26

TABLE I-3

Pacific Connector’s Requests for Modifications to the FERC Staffs Upland Erosion Control, Revegetation and 

Location or 

Activity Requested Modification and Rationale 

According to USFS Standards and Guidelines, LSRs are managed with an objective to protect and enhance habitat for late-successional and old-growth related species. Limited silvicultural treatments are permitted in LSRs. It is Pacific Connector’s opinion that widening the proposed 95-foot construction right-of-way to 105 feet, and likely even more on steep terrain, to accommodate topsoil salvaging, would create more long-term impacts in these habitats than is practical or warranted. The construction footprint has been purposefully 

restricted in LSRs to minimize overall project disturbance. This has been accomplished by reducing the total number of temporary extra work areas in LSRs and limiting these work areas to the minimum size necessary. In forested habitats, the temporary extra work area that would be required to segregate the topsoil on NFS lands would be considered a long-term impact because of the time required to reestablish LSR forest stand characteristics. In forested areas, topsoil would be segregated from the trench line and spoil storage areas, 

and this topsoil would be returned to the same area after trench backfilling. This topsoil segregation area would coincide with the 50-foot permanent easement and the 30-foot corridor centered over the pipeline that would be maintained in a shrub or herbaceous state to facilitate corrosion and leak surveys and for aerial surveillance according to DOT regulations (192.705 Transmission lines: Patrolling and 192.706 Transmission lines: Leakage surveys). Creating long-term impacts to LSR habitats by enlarging the construction right-of-way to segregate topsoil does not provide a benefit compared to the habitat lost. This is 

because the topsoil that would be segregated occurs in the area that would become the permanent 

easement. This area would be maintained in a shrub or herbaceous state. Again, Pacific Connector believes that creating long-term impacts from cutting additional forested areas and causing added disturbance in order to segregate topsoil is not reasonable or advantageous. Pacific Connector would comply with Section VI. B. 2. h. of the FERC Procedures that specifies that the 

topsoil would be segregated in wetlands, except in areas where standing water is present or soils are saturated. Pacific Connector would comply with this measure in all wetlands crossed by the project including those in forested areas. Pacific Connector acknowledges and understands the importance of the soil and topsoil resource and would comply with the USFS and BLM’s request to salvage topsoil if practical on forestlands. However, for the reasons stated above, this request is unreasonable. Pacific Connector would apply the measure outlined in its ECRP to minimize adverse impacts to soil resources, minimize erosion and potential sedimentation, and to appropriately revegetate or reforest all disturbed areas. Pacific Connector would only maintain the 30-foot area centered over the pipeline during long-term operations with these activities typically occurring about every 3 to 5 years. Pacific Connector believes that by utilizing the measures outlined in its ECRP that impacts to site productivity would be minimized and the disturbed areas associated with the right-of-way would restored. The 30 foot area centered over the pipeline, would be converted to a non-forested condition through project maintenance activities. This area would coincide with the typical topsoil salvaging area, therefore, any loss of soil productivity in this area from soil mixing should not inhibit the vegetation communities that Pacific Connector would maintain on the right-of-way (i.e., herbaceous and shrub vegetation). Further, as described in the Resource Reports and its ECRP, slash from forest clearing operations including dead and downed logs and other woody material that occur within the right-of-way would

be salvaged on the edge of the construction right-of-way for redistribution during restoration. This material would provide effective ground cover for erosion control, provide important organic matter for nutrient cycling and provide habitat for all forest species including moss, lichen, fungi and mollusks species, among others.
