~... <br /> <br />Pa ge 6 <br />Colorado Westmoreland, Inc. <br />MLRD/OSM Joint Review <br />December 2, 1980 <br />detail. .What materials arc to be deposited here? The sources and physical <br />properties of these matrrial:: must be identiCicd. f>n any of these materials <br />fit Che dc•finitiou of coal processing waste? What arc the foundation and <br />slope characteristics of the prOpOSCd d1SPOSa.1 area? llow is the site to be <br />prepared prior to dr_positiun of waste materials. Is an undcrdrain system <br />needed? Proposed construction plans, the actual construction, and final <br />stability require certification. A plan view of the completed construction <br />must be provided with appropriate contour interval or alternate surface <br />.runoff indicators to illustrate proposed drainage pattern; cross-sections <br />of the pile should also be provided. <br />to tion and Land Use In fo rrr~tion <br />A discussion of veyctation information would be more useful during the <br />technical analysis if CWI would calculate the acreages and percentages <br />of each veyctation type within the total disturbcrl area. Common understory <br />species should be mentioned Cor the riparian area type and comrnun forbs <br />should be mentioned for the barren area type. Presently, only the pinyon- <br />juniper type has a complete species list in Appendix I (Vol. 77). A <br />complete species List should be included for each type already disturbed or <br />proposcrl to be disturbed. <br />The applicant's plan For vegetation data collection should include a discussion <br />of the demonstration to be made that the reference areas (or other reveyetation <br />standards) are truly representative of the respective vegetation unit. Also, <br />the referenced areas should be at least 3 acres in size, not 2 acres as <br />submitted in supplemental information on October 16, 1980. <br />The application does not include a description of the existing land use <br />classif.ica[ion under local law for the permit area and adjacent areas. No <br />adequate statement of conditions, capability, and productivity of the <br />land affected by surface operations and facilities is made. Productivity <br />information for non-agricultural vegetation types will be obtained From <br />forthcoming baseline data. Productivity information for the orchard area <br />should be available from grower's records. It would be cost effective if <br />the range condition con be determined at the time of baseline data cullrctiua. <br />CWI should check wil:h [heir contractor to see if he/she is qualified to do <br />range condition analyser.. <br />The reveyetation plan roust Prescvrt a more complete schedule of reveyetation. <br />The general rec•lamaLion plan in 784.13(bl(1) is not specific enough to be <br />a schedule of reveyetation. The schedule of revegetation should list the <br />appropriate times for seeding and transplanting and tie in with other mining <br />activities and the best sc,asons for maximwn planting success. <br />t <br />d ~ _ir t ~L~ ~ i <br />
