-~ ~C~ 1 ~ ~L-LG~U '1 Y-{ I.S I~ ~C~vti\l-V.^, I <br />was found to be approximately 384,000 CY. This number is very <br />close to the number calculated using the data for Pit 2 from <br />Figure 2A. Although the volume of 384,000 CY is significantly <br />different from the volume of 300,000 CY calculated using the data <br />of Table 2, the difference is not significant enough to affect <br />the elevation of the proposed reclaimed contours of Phases VIII <br />and IX as a whole and indicate that the proposed reclaimed con- <br />tours for Pit 2 as shown on Figure 2A can probably be achieved. <br />Finally, significant problems concerning overburden and coal <br />quantities were noted during the analysis of the volumetrics <br />given on Table 2 of Addendum II. By converting all the volumes <br />given on Table 2 to BCY it should have be possible to calculate <br />the volume of coal to be excavated during a given year. The <br />equation for this calculation is as follows: ' <br />Tons Coal = 1.12 [(Total Volume-Removed Volume to Stockpile <br />(: 1.15) - (Total Volume Backfilled-Volume from Stockpile) <br />1.20: <br />When this equation was applied to Table 2, however, the following <br />yearly coed volumes were obtained: <br />Year Coal Volume <br />1981 438,000 Tons <br />1982 219,000 Tons <br />1983 271,000 Tons <br />1984 297,000 Tons <br />1985 -187,000 Tons <br />Since. these volumes of coal only matched the projected coal pro- <br />duction as given on page 25 of the permit application in 1984, <br />and since it is not possible to have a negative coal producton <br />(see year 1985, above) another method of determining coal produc- <br />-56- <br />
