Document Description
United proposes to modify its mining operations and reclamation plans for its activities at Pits No. 2 and 3 in the City of Irwindale. Untied has applied for a CUP to modify its operations and the duration of mining activities, and has submitted new reclamation plans. The project also includes merging the un-mined western portion of quarry Pit No. 4 that is now located to the east of the newly constructed Buena Vista Street with the existing quarry Pit No. 2 (increasing the boundary of Pit No. 2 by approximately 25 acres and decreasing the boundary of Pit No. 4); extending the permitted quarry depth in Pit No. 2 to between approximately 410 and 450 below ground surface (bgs), and extending the allowable depth in Pit No. 3 to between 490 and 500 bgs, or mining both pits until December 31, 2020.
