C-2 Evaluate the NRHP Eligibility of P19-186857 and Perform Historical Documentation if Eligible. Prior to construction, the NRHP eligibility of the PS 74 transmission line shall be evaluated by carrying out historical research and determining whether the transmission line facilities retain integrity of workmanship, design, and materials. If the Forest Service and the SHPO determine the transmission line is eligible (and therefore also a CEQA Historical Resource), the adverse effect will be mitigated by formulating and implementing a mitigation plan. The mitigation plan will require historical documentation to standards set by the SHPO. The documentation will preserve information on all of the characteristics that made the resource eligible. Documentation will be achieved through historical research and high resolution photography of an example tower that meets standards set by the SHPO with the results provided in a report to be filed with the California Historic Resources Information System (CHRIS), the California Public Utilities Commission (CPUC), the Forest Service, and the California Office of Historic Preservation (OHP). The CPUC and U.S. Forest Service will ensure that the documentation is completed and filed.

C-7a Avoid CA-LAN-3478. CA-LAN-3478 shall be avoided by all Project construction activities. Avoidance and protection may be achieved by implementing measures for avoidance, such as moving tower locations or using non-destructive construction methods, contained in the PA between the USDA Forest Service and the California State Historic Preservation Officer. The site will be fenced off as an environmentally sensitive area during construction.

C-7b Evaluate the NRHP Eligibility of CA-LAN-3478 and Perform Historical Documentation and/or Archaeological Data Recovery if Eligible. Prior to construction, the NRHP eligibility of CA-LAN-3478 shall be evaluated by carrying out historical research and an archaeological test program to determine whether subsurface archaeological material is present that has the potential to yield information important in prehistory. If the Forest Service and the SHPO determine the site is eligible under Criterion D (and therefore also a CEQA Historical Resource), an archaeological data recovery program, consisting of hand excavated units, identification and cataloging of recovered material, and a report, will be completed for the portion of the site that will be impacted as a result of Project construction activities. The CPUC and. Forest Service will ensure that the data recovery report is completed and filed with the California Historic Resources Information System (CHRIS), the California Public Utilities Commission (CPUC), the Forest Service, and the California Office of Historic Preservation (OHP). If the site is determined eligible under Criteria A or B (and therefore also a CEQA Historical Resource), the adverse effect will be mitigated by formulating and implementing a mitigation plan. The mitigation plan will require historical documentation to standards set by the SHPO. The documentation will preserve information on all of the characteristics that made the resource eligible. Documentation will be achieved through historical research and high resolution photography that meets standards set by the SHPO with the results provided in a report to be filed with the California Historic Resources Information System (CHRIS), the California Public Utilities Commission (CPUC), the Forest Service, and the California Office of Historic Preservation (OHP). The CPUC and Forest Service will ensure that the documentation is completed and filed.

C-8a Avoid CA-LAN-1334/H. CA-LAN-1334/H and the Cochem Ranch buildings shall be avoided by all Project construction activities by moving the location for proposed new tower T-104 off-site and removing existing tower 23-2 without disturbing the ground, in accord with the avoidance and protection measures in the PA between the USDA Forest Service and the California State Historic Preservation Officer. The site will be fenced off as an environmentally sensitive area during construction.

C-8b Evaluate the NRHP eligibility of CA-LAN-1334 and Cochem Ranch and Perform Historical Documentation and/or Archaeological Data Recovery if Eligible. Prior to initiating any construction activities in the vicinity of CA-LAN-1334/H, an archaeological test program will be completed in order to provide information necessary to evaluate the prehistoric component of CA-LAN-1334/H for eligibility for the NRHP. If the Forest Service and SHPO determine that the site is eligible under Criterion D (and therefore also a CEQA Historical Resource), an archaeological data recovery program, consisting of hand excavated units, identification and cataloging of recovered material, and a report, will be completed for the portion of the site that will be impacted by removal of existing tower 23-2 and for the portion of the site that will be impacted for installation of proposed new tower T-104, if this proposed tower location cannot be moved off the archaeological site. The CPUC and Forest Service will ensure that the data recovery report is completed and filed with the California Historic Resources Information System (CHRIS), the California Public Utilities Commission (CPUC), the Forest Service, and the California Office of Historic Preservation (OHP). The complex of buildings and structures known as the Cochem Ranch will be evaluated for NRHP eligibility by an architectural historian prior to construction. If the Forest Service and SHPO determine that the Cochem Ranch is eligible under Criteria A, B, or C (and therefore also a CEQA Historical Resource), the adverse effect will be mitigated by formulating and implementing a mitigation plan. The mitigation plan will require historical documentation to standards set by the SHPO. The documentation will preserve information on all of the characteristics that made the resource eligible. Documentation will be achieved through historical research and high resolution photography that meets standards set by the SHPO with the results provided in a report to be filed with the California Historic Resources Information System (CHRIS), the California Public Utilities Commission (CPUC), the Forest Service, and the California Office of Historic Preservation (OHP). The CPUC and Forest Service will ensure that the documentation is completed and filed.

C-10a Avoid CA-LAN-3479. CA-LAN-3479 shall be avoided by all Project construction activities by moving the location of proposed new tower T-107 away from the site, one of the measures for avoidance in the PA between the USDA Forest Service and the California State Historic Preservation Officer. The site will be fenced off as an environmentally sensitive area during construction.

C-10b Evaluate the NRHP Eligibility of CA-LAN-3479 and Perform Archaeological Data Recovery if Eligible. If site CA-LAN-3479 cannot be avoided, prior to initiating any construction activities in the vicinity of CA-LAN-3479, an archaeological test program will be completed in order to provide information necessary to evaluate the CA-LAN-3479 for eligibility for the NRHP. If the Forest Service and SHPO determine that the site is eligible (and therefore also a CEQA Historical Resource), an archaeological data recovery program, consisting of hand excavated units, identification and cataloging of recovered material, and a report, will be completed for the portion of the site that will be impacted as a result of Project construction activities. The CPUC and Forest Service will ensure that the data recovery report is completed and filed with the California Historic Resources Information System (CHRIS), the California Public Utilities Commission (CPUC), the Forest Service, and the California Office of Historic Preservation (OHP).

C-12 Evaluate the NRHP Eligibility of CA-LAN-3477 and Perform Historical Documentation if Eligible. Prior to construction, the NRHP eligibility of CA-LAN-3477 shall be evaluated by carrying out historical research. If the Forest Service and the SHPO determine that CA-LAN-3477 is eligible (and therefore also a CEQA Historical Resource), effects will be assessed and a mitigation plan will be formulated and implemented if effects will be adverse. The mitigation plan will require historical documentation to standards set by the SHPO. The documentation will preserve information on all of the characteristics that made the resource eligible. Documentation will be achieved through historical research and high resolution photography with the results provided in a report to be filed with the California Historic Resources Information System (CHRIS), the California Public Utilities Commission (CPUC), the Forest Service, and the California Office of Historic Preservation (OHP). The CPUC and U.S. Forest Service will ensure that the documentation is completed and filed.

C-13a Avoid P19-120077. P19-120077 shall be avoided by all Project construction activities. Avoidance and protection may be achieved by implementing measures for avoidance, such as moving tower locations or using non-destructive construction methods, contained in the PA between the USDA Forest Service and the California State Historic Preservation Officer. The site will be fenced off as an environmentally sensitive area during construction.

C-13b Evaluate the NRHP Eligibility of P19-120077 and Perform Archaeological Data Recovery if Eligible. If site P19-120077 cannot be avoided, prior to initiating any construction activities in the vicinity of P19-120077, an archaeological test program will be completed in order to provide information necessary to evaluate P19-120077 for eligibility for the NRHP. If the Forest Service and SHPO determine that the site is eligible (and therefore also a CEQA Historical Resource), an archaeological data recovery program, consisting of hand excavated units, identification and cataloging of recovered material, and a report, will be completed for the portion of the site that will be impacted as a result of Project construction activities. The CPUC and Forest Service will ensure that the data recovery report is completed and filed with the California Historic Resources Information System (CHRIS), the California Public Utilities Commission (CPUC), the Forest Service, and the California Office of Historic Preservation (OHP).

C-14 Conduct Construction Monitoring in Sensitive Areas in the Project Area, Evaluate the Eligibility of Previously Undiscovered Resources, and Perform Archaeological Data Recovery if Eligible. All Project-related ground-disturbing activities in sensitive areas, defined as on ridge tops and in canyon bottoms and within 500 feet of identified resources, shall be monitored by an archaeologist. If an archaeological site is discovered during monitoring, all work within 500 feet of the find shall be halted and the Forest Service District Ranger or Forest Supervisor shall be notified. The Forest Service will evaluate the NRHP eligibility of the find if it cannot be avoided. If the Forest Service and SHPO determine that the site is eligible (and therefore also a CEQA Historical Resource), an archaeological data recovery program, consisting of hand excavated units, identification and cataloging of recovered material, and a report, will be completed for the portion of the site that will be impacted as a result of Project construction activities. The CPUC and Forest Service will ensure that the data recovery report is completed and filed with the California Historic Resources Information System (CHRIS), the California Public Utilities Commission (CPUC), the Forest Service, and the California Office of Historic Preservation (OHP). Construction work that was halted within 500 feet of the find cannot proceed until authorized by the District Ranger or Forest Supervisor.
