Lots 1 (Parcel Number 2100490030200, 105.2 acres) and Lot 2 (Parcel Number 2629330320175, 97.11 acres) will be consolidated to allow for the plant to be placed into the preferred location, minimizing environmental impacts. Lot 3 (Parcel Number 2629280120001, 160 acres) will require some improvements to the 1.1-mile private road access extending from McManamon Road. See site maps for location.
