52.04 APPLICATION FOR PERMIT FOR SURFACE OR UNDERGROUND MINING ACTIVITIES -- <br />MINIMUM REQUIREMENTS FOR INFORMATION ON ENVIRONMENTAL RESOURCES. <br />• 2.04.10 Vegetation Information. <br />(1) Plant community types affected by surface operations and fa- <br />cilities were originally delineated in CWI's 1977 application, <br />Map 9A-1 in Volume 9A shows the original plant community de- <br />lineations as well as information prepared in 1984 on the re- <br />mainder of the permit area. Refer to to the Vegetation Ap- <br />pendix in Volume 9A for a description of the community types. <br />A detailed vegetation inventory and mapping in the area of the <br />Orchard Valley West Mine was completed by Harner & Associates, <br />Inc. during July, 1986. Refer to the Vegetation Map with this <br />report in the Vegetation Appendix in VolLane 9A for further in- <br />formation. <br />(2) Reference area locations have been previously approved and are <br />shown on Map 9A-1. <br />(3) See Map 4A-1 showing vegetation for the entire permit area and <br />adjacent lands. In the case of underground mining, only the <br />area to be affected by surface operations or facilities is re- <br />quired. For a complete evaluation of resources, the entire <br />permit area is shown. <br />• (4) Baseline vegetation data for the Orchard Valley Mine were ini- <br />tially obtained by Thorne Ecological Institute in 1977 during <br />the construction of existing mine surface facilities. This <br />information provided a brief qualitative description of the <br />vegetation types within the disturbed area and met existing <br />baseline requirements. <br />Colorado Westmoreland Inc. retained Harner-Glhite Ecological <br />Consultants of Littleton, Colorado, to obtain additional vege- <br />tation information during 1981. This study describes the ma- <br />jor plant community types within the original permit area. In <br />addition, a comprehensive species list was generated from this <br />inventory. <br />Reference areas were also established for the vegetation com- <br />munities that were disturbed by the construction of mine fa- <br />cilities. <br />In 1982, Harner-White conducted additional vegetation inven- <br />tories of herbaceous reference areas so that a reclamation <br />success standard could be established. Reclamation seed mixes <br />were also developed from this information. <br />Revised 08/01/84 <br />• Revised 10/12/86 <br />Revised 10/01/87 <br />70 <br />
