The <br /> same question is applicable for this page in King II Section 2.03.8. <br /> 2) In King I Mine Section 2.03.8, it appears that the change in disturbed area may be incorrect. <br /> It was increased 2.15 acres, but the stated increase on page 3A in Section 2.05.3 is 2.51 acres. <br /> On Page 6 in Section 2.05.3 (last paragraph), please check the value of 2.15 acres. In one or <br /> the other places the numbers may have been transposed. Please clarify that the proposed <br /> disturbed acreage remain consistent. <br /> 3) Regarding King II Mine Section 2.04.6 page 8, is the page number correct? Does GCC <br /> Energy intend to delete the section Refuse Pile Chemistry in the existing PAP, which is <br /> currently on page 8? <br /> 4) On page 3A in Section 2.05.3, please provide more detail to describe where the new spoil <br /> material will be stored. Please show the location on a map. <br /> 5) Page 3A in Section 2.05.3,please state if the pond size did or did not change with the <br /> increased disturbed area. <br /> 6) On Page 5 in Section 2.05.3, text regarding sampling runoff from SAES has been removed. <br /> Please explain. Also on this page, please explain if the two 24" culverts are C22. <br /> Q <br /> 1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 http://mining.state.co.us * *� <br /> Jared S.
