Utilities Commission (CPUC).3 The VFD has compared VMUS' WMP against existing practices and any comparable actions planned by the IOUs.
Physical Inspections: Because of the VFDs role in the City of Victorville along with great collaboration with Mission Fire Rescue, the VFD has access to and regularly inspects the City of Victorville's facilities, including electrical infrastructure. Therefore, the VFD has access to prior data on the fire mitigation decisions and performance of VMUS. The VFDs evaluation of VMUS' WMP draws upon this data and experience.
D. METRICS
VMUS' WMP proposes the following metrics to measure performance of its wildfire mitigation measures: (1) number of fire ignitions,4 and (2) wires down events.5 . The VFD will evaluate the metrics selected in Phase 2 of the CPUC's current Wildfire Mitigation Plan rulemaking for the IOUs (R.18-10-007) and determine if any additional metrics should be incorporated into future VMUS' WMPs.
3 IOU WMPs are available at: https://www.cpuc.ca.gov/SB901/.
4 For purposes of this metric, a fire ignition is defined as follows: (i) VMUS facility was associated with the fire; (ii) the fire was self-propagating and of a material other than electrical and/or communication facilities; (iii) the resulting fire traveled greater than one linear meter from the ignition point; and (iv) VMUS has knowledge that the fire occurred.
5 For purposes of this metric, a wires down event includes any instance where an electric transmission or primary distribution conductor falls to the ground or on to a foreign object.
