CSOLAR is requesting five modifications to the access roads and vehicle turnarounds along the transmission corridor alignment.
Widen Access Road. This requested modification is to widen the access road within the transmission line corridor from 12 feet wide to 14 feet wide so that larger equipment (e.g., cranes and flat-bed trucks) used during construction and maintenance activities can maneuver along the road. Widening the access road will require additional grading to create the wider road surface but will not result in an increased number of construction or operations trips on this road.
Minor Relocation of the Access Road Alignment. This requested modification is to shift and relocate segments parts of the access road within the transmission line corridor to be adjacent to the permanent operations and maintenance work pad locations. The modified access road alignment would still be within the temporary disturbance areas to reduce disturbance on BLM lands. The minor relocations will require grading along a different alignment than under the approved project but will not result in an increased number of construction or operations trips on this road.
Straighten the Access Road Alignment. This requested modification is to straighten certain segments of the access road to improve the existing turning radii, to allow large construction and maintenance trucks and equipment to safely maneuver along the access road. These modifications to the access road include secondary vehicular construction access so that construction equipment does not have to drive through work zones occupied by other construction vehicles and personnel. Straightening the access road will require grading along a different alignment but will not result in an increased number of construction or operations trips on this road.
Vehicle Turnaround. This requested modification is to provide a vehicle turnaround area near the Imperial Valley Substation for trucks and equipment to safely and efficiently maneuver on site. CSOLAR has coordinated with Campo Verde, IID, and SDG&E for both its interconnection to the Imperial Valley Substation and the requested turnaround area for vehicles. The vehicle turnaround will require a small amount of additional grading compared to the approved project.
Secondary Vehicular Construction Access. This requested modification is for approval of the use of alternate routes for construction traffic so that construction equipment does not have to drive through work zones occupied by other construction equipment and construction workers. CSOLAR is specifically requesting approval of the use of the following existing roads as alternative routes for construction access:
• The unnamed route that connects State Route 98 to the Imperial Valley Substation that was used by SDG&E during construction of the Sunrise Powerlink project
• BLM Routes 358 and 410 for access to/from Interstate 8 to/from the Imperial Valley Substation
• The unnamed road around the east side of the Imperial Valley Substation, which provides access from State Route 98 to the Imperial Valley Substation via its connection to Route 358.
A.2 Modifications to the Transmission Line Design and Structure Locations
CSOLAR is requesting six modifications to the transmission line design and structure locations along the transmission corridor alignment.
Modifications to the Connection to the Imperial Valley Substation. The approved Transmission Interconnection Line was at the western edge of the Imperial Valley Substation. CSOLAR has been assigned a specific electrical bus by SDG&E which is near the middle of the substation. CSOLAR is requesting that BLM to accept this re-assignment location as determined by SDG&E. Structures 1 to 4 on BLM land will need to be moved accommodate this design change and to avoid impacts to the recently constructed Campo Verde facilities.
Future Installation of a Second Circuit. This modification requests the flexibility of installing a second circuit at a later date onto the Transmission Interconnection Line. This modification would reduce and avoid additional impacts on BLM-managed lands by allowing the use of the Transmission Interconnection Line to carry additional circuit capacity in the future. The installation of that second circuit would be conducted similar to the installation of the circuit in the approved project. Temporary pulling stations and work areas, at the locations used for the installation of the first circuit, would be used to install the second circuit. As a result, some of the areas temporarily disturbed for the installation of the first circuit would be disturbed again in the future for the installation of the second circuit. No areas not already temporarily disturbed for the first installation would be disturbed during the second installation.
Reduction in the Number of Tower Structures and Relocation of Some Towers. The approved project included 41 tower structures along the gen-tie line alignment. This request is to reduce in the total number of tower structures from the original 41 structures to 34 structures and to shift the locations of some of those towers. The 34 structures will be spaced within the Transmission Interconnection Line corridor with approximately 300 feet to 1,050 feet between structures, with the structures an average of 850 feet apart. This includes the relocation of Structures 1 to 4 to accommodate the SDG&E assigned electrical bus described above.
Shifts in the Locations of the Construction Work Areas at Structure Footings. This modification requests approval of potential shifts of the defined temporary work areas at up to 25 of the 34 structure footings. The intent is to have the opportunity to locate the 100 foot by 100 foot work areas for tangent structures and the 140 foot by 140 foot work areas for deflection structures within the Transmission Interconnection Line corridor to provide for the most efficient construction staging/activities and use of construction equipment in those work areas. The potential areas considered for shifting work areas range up to over 300 feet in diameter centered on the previously defined construction work areas. The potential alternate work areas were assessed and refined to ensure that those work areas would not overlap ESAs in or adjacent to the 120-foot wide transmission line corridor.
Shifts in the Locations of Permanent Work Areas as the Structure Footings. This modification requests approval of potential shifts in the permanent work areas for operations and maintenance activities. Tangent structures will have a single 50 foot by 75 foot permanent work pad that would mostly overlap with the temporary work pad locations. Larger turning and dead-end structures would contain two approximately 35 foot by 150 foot permanent work pad areas that would also mostly overlap with the temporary work pad locations.
Burial of the Optical Ground Wire for Communications. This modification requests approval of undergrounding the Optical Ground Wire (OGW) for communications as it enters the Imperial Valley Substation from Structure 1. The trenching work for burying the OGW would occur from Structure 1 to the Imperial Valley Substation fence area.||West Imperial County, CA||Nicollee Gaddis|

|DOI-BLM-CA-D070-2014-0051||CX||Lands and Realty||The proponent previously installed and will continue to maintain approximately 400 water stations in the east and west desert of Imperial County to minimize deaths of undocumented immigrants from dehydration. Stations vary between two designs: one style consists of a 2ft x 3ft flag on a 20-30ft flagpole sleeved over a length of rebar driven flush with the ground. Two to four gallons of sealed water bottles will be placed in a cardboard or plastic box at each station. The second style consists of a blue, open-top 55-gallon polyethylene barrel. The barrels have holes in the bottom for drainage. The barrels are secured with bricks, concrete blocks, or other means that does not involve the use of native material, so that they do not blow away. Approximately 10 1-gallon plastic jugs of water are put inside the barrels. These sites also have a flag as described above for visibility.
The water stations will continue to be maintained and replenished every two weeks at a minimum, more frequently if determined necessary, by the proponent and other volunteers. ||East and West Deserts of Imperial County, CA||Veronica Vogan|
