Following the implementation of these mitigation measures, there should be no residual impacts
to vegetation.
Implementation of the proposed action would increase the potential for human caused fires
during construction and operation of the proposed Project. Accidental discharge during
transportation and storage of flammable materials or chemicals (such as pentane or fuel) could
accelerate the ignition of fires along the County Road or at the power plant site. Impacts from
these fires would vary based on fire size and could result in the destruction of structures,
livestock forage, and wildlife habitat.
