Public Health and Safety

PH-1a Environmental Training and Monitoring Program. An environmental training program will be established to communicate environmental concerns and appropriate work practices, including spill prevention, emergency response measures, and proper Best Management Practice (BMP) implementation, to all construction and maintenance personnel. The training program will emphasize site-specific physical conditions to improve hazard prevention (e.g., identification of potentially hazardous substances) and will include a review of all site-specific plans, including but not limited to, the Project's SWPPP, Erosion Control and Sediment Transport Plan, Waste Characterization and Management Plan, and Hazardous Substances Control and Emergency Response Plan. Properly trained construction and maintenance staff are expected to prevent accidental hazardous materials spills and in the event of a spill will be able to quickly ascertain the best way to stop and mitigate the spill, thus limiting potential soil contamination.

A monitoring program will also be implemented to ensure that the plans are followed throughout the period of construction. Best Management Practices, as identified in the Project SWPPP and Erosion Control and Sediment Transport Plan, will also be implemented during the construction of the Project to minimize the risk of an accidental release and provide the necessary information for emergency response.

PH-1b Hazardous Substance Control and Emergency Response Plan. SCE will prepare a Hazardous Substance Control and Emergency Response Plan, which will include preparations for quick and safe cleanup of accidental spills. This plan will be submitted with the grading permit applications to the appropriate oversight agency based on grading location. It will prescribe hazardous-materials handling procedures for reducing the potential for a spill during construction, and will include an emergency response program to ensure quick and safe cleanup of accidental spills. The plan will identify areas where refueling and vehicle maintenance activities and storage of hazardous materials, if any, will be permitted. These directions and requirements will also be reiterated in the Project SWPPP. SCE shall document compliance with this measure prior to the start of construction by submitting the plan to the CPUC and Forest Service for review.

PH-1c Proper Disposal of Construction Waste. All construction and demolition waste, determined to be potentially hazardous, including trash and litter, garbage, other solid waste, petroleum products and other potentially hazardous materials, will be removed to a hazardous waste facility permitted or otherwise authorized to treat, store, or dispose of such materials. Waste materials shall be removed from the project staging areas in a manner consistent with California Integrated Waste Management Board standards for transportation and disposal of hazardous materials, based on Title 27, Environmental Protection Division 2, Solid Waste.

PH-1d Emergency Spill Supplies and Equipment. Hazardous material spill kits will be maintained on-site for small spills. This shall include oil-absorbent material, tarps, and storage drums to be used to contain and control any minor releases. Emergency-spill supplies and equipment will be kept adjacent to all areas of work and in staging areas, and will be clearly marked. Detailed information for responding to accidental spills and for handling any resulting hazardous materials will be provided in the Project's Hazardous Substances Control and Emergency Response Plan.

PH-2 Conduct Phase II Investigation. A Phase II investigation shall be conducted for any sites revealed to be potentially contaminated by the Phase I ESAs prior to commencement of construction activities. The Phase II investigation shall include a review of current status from agency files of known contaminated sites, including identification of the concentration and limits of contamination, type of release, and media affected; and collection of samples for laboratory analysis and quantification of contaminant levels within the proposed excavation and surface disturbance areas in areas of known and potential contamination. The scope of the field investigation shall be developed in accordance with the standard of practice for assessment of appropriate worker protection and material handling and disposal procedures. Soil sampling and laboratory testing shall be conducted at locations along the Project route where known contaminated sites are within 0.25 miles of the tower locations and substations or are determined to pose a threat to the Project based on the results of agency file review. The Phase II shall be conducted and recommendations completed prior to the start of construction.

Subsurface investigation shall determine appropriate worker protection and hazardous material handling and disposal procedures appropriate for the subject area. Areas with contaminated soil and/or groundwater determined to be hazardous waste shall be removed by personnel who have been trained through the OSHA recommended 40-hour safety program (29CFR1910.120) with an approved plan for groundwater extractions, soil excavation, control of contaminant releases to the air, and off-site transport or on-site treatment. Results of the agency file review and Phase II investigations shall be reviewed and approved by the County of Los Angeles Fire Department, Health Hazardous Materials Division and/or DTSC prior to construction. A copy of the DTSC or Health Hazardous Materials Division approval letter must be provided to the CPUC prior to start of construction.

PH-3 Observe Exposed Soil. During grading, or excavation work for the Project, the contractor shall observe the exposed soil for visual evidence of contamination. If visual contamination indicators are observed during construction, the contractor shall stop work until the material is properly characterized and appropriate measures are taken to protect human health and the environment. The contractor shall comply with all local, State, and federal requirements for sampling and testing, and subsequent removal, transport, and disposal of hazardous materials. In the event that evidence of contamination is observed, the contractor shall document the exact location of the contamination and shall immediately notify the CPUC's Environmental Monitor and propose actions for addressing the contamination. A weekly report listing encounters with contaminated soils and describing actions taken shall be submitted to the CPUC.

PH-4a Documentation of Compliance. SCE shall document compliance with updating and preparing the SPCC Plan for this project by (a) submitting to the CPUC for review and approval an outline of the proposed Environmental Training and Monitoring Program, (b) providing a list of names of all operations personnel who have completed the training program, and (c) providing a copy of the SPCC plans to the CPUC for review and approval at least 60 days before the start of operation.

PH-4b Emergency Spill Supplies and Equipment. Hazardous material spill kits will be maintained in maintenance vehicles for small spills. This shall include oil-absorbent material, and spill kits to be used to contain and control any minor releases. During significant maintenance operations, emergency-spill supplies and equipment will be kept adjacent to all areas of work and in staging areas, and will be clearly marked. Detailed information for responding to accidental spills and for handling any resulting hazardous materials will be provided in the Project's Hazardous Substances Control and Emergency Response Plan.

PH-5a Limit the Conductor Surface Electric Gradient. As part of the design and construction process for the Project, the Applicant shall limit the conductor surface electric gradient in accordance with the IEEE Radio Noise Design Guide.

PH-5b Document and Resolve Electronic Interference Complaints. After energizing the transmission line, SCE shall respond to and document all radio/television/equipment interference complaints received and the responsive action taken. These records shall be made available to the CPUC for review upon request. All unresolved disputes shall be referred by SCE to the CPUC for resolution.

PH-6 Determine Proper Grounding Measures. As part of the siting and construction process for the Project, SCE shall identify objects (such as fences, metal buildings, and pipelines) that have the potential for induced voltages and work with the affected parties to determine proper grounding procedures (CPUC G095 and the NESC do not have specific requirements for grounding). SCE shall install all necessary grounding measures prior to energizing the line. Thirty days prior to energizing the line, SCE shall notify in writing, subject to the review and approval of the CPUC, all property owners within and adjacent to the Project ROW of the date the line is to be energized. The written notice shall provide a contact person and telephone number for answering questions regarding the line and guidelines on what activities should be limited or restricted within the ROW. SCE shall respond to and document all complaints received and the responsive action taken. These records shall be made available to the CPUC for review upon request. All unresolved disputes shall be deferred by SCE to the CPUC for resolution.

The written notice shall describe the nature and operation of the line, and the Applicant's responsibilities with respect to grounding all conducting objects. In addition, the notice shall describe the property owner's responsibilities with respect to notification for any new objects, which may require grounding and guidelines for maintaining the safety of the ROW.
