The California Energy Commission has adopted a set of voluntary guidelines for wind power projects in the state, as reported by The Birding Community E-Bulletin. The document’s abstract:
These voluntary guidelines provide information to help reduce impacts to birds and bats
from new development or repowering of wind energy projects in California. They
include recommendations on preliminary screening of proposed wind energy project
sites; pre-permitting study design and methods; assessing direct, indirect, and
cumulative impacts to birds and bats in accordance with state and federal laws;
developing avoidance and minimization measures; establishing appropriate
compensatory mitigation; and post-construction operations monitoring, analysis, and
reporting methods.
The guidelines were developed in conjunction with the California Department of Fish and Game.
