After certification of the Final EIR for the Pine Tree Wind Project, Aspen prepared detailed air pollutant emission calculations for the Los Angeles Department of Water and Power (LADWP) to quantify impacts associated with changes in earth movement quantities. These changes resulted from the development of more detailed engineering plans for the wind energy development, primarily associated with road construction. Aspen also consulted with LADWP on necessary documentation for CEQA compliance for this project change.
