United States Gypsum Company (USG) Expansion/Modernization Project (DEIR)
NOP - Notice of Preparation of a Draft EIR
Generally the proposed project consists of construction of new buildings, a doubling in wallboard production by removing one operation production wallboard line and installing a new, state-of-the-art high speed line and increased mining of gypsum from 1.1 million tons per year (mty) to approximately 1.9 mty on land reserves owned and mined by USG. The Proposed Project also consists of expanding existing and planned quarry areas and creating a new overburden storage site. To accommodate the expanded operations water usage will increase. The project will also include modernizing the existing warehouses, storage structures, rail loading facility and upgrading electrical transmission lines, maintaining the 26-mile narrow gauge rail line which runs between the Plaster City plant and the quarry, replacing the 26-mile existing pipeline that runs between Ocotillo and the plant relocating a short portion of the interstate rail that runs through the Plaster City Plant. Accumulated off-specification materials are intended to be recycled.
