(a) Mandated wildfire mitigation is the PacifiCorp investment reason for all
wildfire mitigation capital projects. Generally, these projects are considered
mandated to comply with a filed wildfire mitigation plan (WMP) in the state
where the investment takes place. Given that this is the name of the

vehicles are unable to travel in order to comply with Company policies and /
or federal, state or local permit requirements for suppression and risk
mitigation.

Backhoes (and trailers): Provide clearing capability of wildland vegetation
(brush, trees, etc.) in fire high consequence areas (FHCA ) to create work
platform to protect vehicles from igniting dry vegetation while working in
order to comply with Company policies and / or federal, state or local permit
requirements for suppression and risk mitigation.

(5) “Span Fk-Santaquin 46kV Rbld for Wildfire”:

(a) The Spanish Fork to Santaquin 46 kV transmission line is located in the
Fire High Consequence Area (FHCA) for a distance of about 3.82 miles
near Salem, Utah. As part of the wildfire Mitigation plan (WMP), all
transmission lines were reviewed that were inside the determined FHCA
that was modeled by Reax Engineering. All wood constructed
transmission lines inside the FHCA that will be over the age of 40 by the
end of the seven-year WMP were determined in need of being replaced
with all new materials built to our current transmission standards. The
average age of wood poles on this line is already over this 40-year
threshold; therefore this line is being rebuilt to mitigate the risk of igniting
a fire in the Salem area. This rebuild will include all new fire wrapped
wood poles and Hendrix Spacer Cable Conductor System.

Scope of work:
