Document Type
NOP - Notice of Preperation
Present Land Use
A-1 (Limited Agriculture), M-3 (Heavy Industrial), E-20 (Estate 20 acres), and R-1 (Low Density Residential)

Document Description
The proposed project includes increasing the maximum footprint of the open pit mine area; increasing the overburden stockpile area and height; expansion of the gangue material storage area; construction of new boric acid ponds and an expansion of the Boric Acid Plant. An area between the designed crest of the highwall, and the designed toe of the overburden stockpiles is being provided as a contingency area. This area is being provided in the event that the pit crest or the overburden toe needs to extend beyond the limits indicated. It may also be used for miscellaneous needs such as access roads, storage of equipment, supplies, etc. The proposed project has been designed for the impacts evaluated based upon a foreseeable remaining mine life of 40 years. The proposed project will increase the maximum footprint of the pit from the approximate 1,731 acres currently permitted to a range of 2,615 acres to a maximum of 3,254 acres (if the pit is required to utilize the entirety of the contingency area described above).
