• CDPH&E - 2 - February 9, 1996 <br />Blasting in preparation of the site will include 2 blasts per <br />day, 120 blasts per year, and 60 days per year. <br />Coal and rock will be removed from the mine at 2,000,000 tons per <br />year and 20,000 tons per day (maximum) by the portal conveyor <br />with a capacity of 1200 tons per hour. Within an enclosed <br />transfer tower building, the coal or rock drops from the conveyor <br />through a flop gate. Waste rock is taken by the gob belt to a <br />temporary gob pile. A maximum of 1500 tons will be stored at any <br />one time in the temporary gob pile and remain undisturbed for one <br />week at a time. Material is loaded out of this gob pile by <br />front-end loader and trucks and taken to the permanent gob pile <br />4.6 miles away. Coal is transported from the flop gate by the <br />stockpile conveyor, and passes through the stacking tube into an <br />open stockpile The coal stockpile includes the reject pile <br />from the rotary breaker and will have a maximum of 60,000 tone of <br />coal stored at any one time. Coal is loaded out from this <br />stockpile by enclosed feeders to the reclaim conveyor and then to <br />the first screen. <br />Material smaller than six inches (1,475,000 tons/year) passes <br />through the screen and bypasses the rotary breaker by the <br />transfer conveyor to a second screen. Larger material is fed <br />• through the rotary breaker (475,000 tons/year). Coal from the <br />rotary breaker (450,000 tons/year) passes to the transfer <br />conveyor and on to the second screen, while 25x000 tons/year of <br />oversize material from the rotary breaker is transported by the <br />rock conveyor to a reject stockpile (included with the open coal <br />stockpile as mentioned in the previous paragraph). <br />From the second screen, smaller material (962,500 tons/year) <br />bypasses the double roll crusher to the downhill conveyor and <br />962,500 tons/year feeds through the double roll crusher and then <br />to the downhill conveyor. The coal drops from the downhill <br />conveyor through a flop gate with 1,725,000 tons per year going <br />directly to the loadout silo (finished product stockpile in the <br />application) and 200,000 tons/year passing through a third <br />screen. From this screen 100,000 tons of coal per year goes to <br />the loadout silo, and 100,000 tons/year is taken by the stoker <br />transfer conveyor to a stoker bin, and by the stoker loadout <br />conveyor to the truck loadout bin below the loadout silo. The <br />maximum stored at one time in the silo is 6100 tons. Coal is <br />loaded out of the silo by truck. The haul road distance (one <br />way) is 0.14 miles. <br />Employee vehicles, and service and delivery vehicles will use the <br />road from State Highway 133 to the employee parking lot, a <br />• distance of 1.9 miles, one way. <br />The fugitive emissions were calculated according to the <br />following. All emission factors, methods for estimating emission <br />
