Proximity Scanner 與 Lineman Guide 使用情況與統計

The Proximity Scanner is intended for use by PG&E employees and contract-staff. The app uses your phone's GPS to verify WDR permit coverage and local environmentally sensitive areas, including contaminated sites, wetlands, and Areas of Special Biological Significance (ASBS). It considers the extent of each Regional Water Quality Control Board (RWQCB) and contaminated sites in the RWQCB and Department of Toxic Substances Control (DTSC) listed sites within PG&E’s service area in California. The Proximity Scanner App is to be used in conjunction with the Vault Dewatering form as part of the vault dewatering procedure and helps PG&E Employees and Contractors determine if clean vault water may be discharged to land in certain locations after land owner approval is received and documented.
