' C. PROPOSED MINING OPERATION <br /> 1 . General Operating Methods: The operation proposed for the site is an open <br /> ' pit gravel operatiqn utilizing normal construction equipment, including <br /> ' loaders and scrapers. This equipment will operate in a manner normally <br /> used in both dry gravel mining methods and construction excavations. No <br /> ' blasting will be required. During the time the actual mining operation <br /> occurs, farming will continue on the portions of the site where farming <br /> ' is now conducted and which are not actually disturbed at that time by <br /> ' the mining operation. As will be described below, it is the intention of <br /> the mining and reclamation process to return the land to a productive, <br /> ' farmable condition as soon after mining has taken place as possible. As <br /> a result , the mining operation has been designed to disturb as little <br /> ' farm land at any given time as possible, and to allow continued irrigation <br /> ' of the land as long as possible. <br /> The mining operation described in more detail below has been designed to <br /> minimize the area disturbed at any one point in time as well as to <br /> ' minimize double handling of materials , specifically overburden. The <br /> block-cut method of mining is proposed for extraction operations at the <br /> ' site. Conceptually, as the overburden is removed from a given area it <br /> will be placed directly in the area which has been previously mined. <br /> After the overburden is removed from an area, the gravel will be removed <br /> ' from that area until the water table is encountered. (At that time, either <br /> well points will be installed, or a de-watering trench will be excavated <br /> ' around as much of that area as is required to de-water that particular <br /> i <br /> ' area. Essentially, the water table will be lowered by pumping only in <br /> -10- <br />
