~ ~ ~ ~ Pursuant to 783.12, applicant should provide t'minq;df soil stripping, backfilling and grading. i " " ~ Pursuant to 783.21, applicant should indicate~ocatiori of soil sampling sites and demonstrate how reclamation limitation of soils were obtained. ~ Applicant should include higher taxonomic orders of soils in table no. 4.4-1, as indicated in Section 4.4.3of the appli- cation, and provide information for the establishment 'of a reference area including a description. ~~I 19. Alternative Water Supply (783.17) Identify water supplies within and outside of lthe permjit area; identify extent to which the proposed mining activities may adversely impact such supplies; if adverse~impactsmay occur, then identify alternative sources for use as replace- ment supplies--in accordance with 783.17. Locate supplies and sources on maps or other illustration--in accordance with 783.25(f) and (g) and with 783.24(8). All alternative water supply informtion must comply with Colorado water law. i i 20. Climatological Information (783.18) More detail is necessary in the precipitation $~~ummaries. As required for the evaluation of the reclamatiion plan; monthly and annual mean, maximum and minimum water equivalent. precipitation totals should be provided. These summaries should be based on at least ten(10) years of data from a station such as Fruita. The data period used should be _ specified. I The Grand Junction wind rose presented in Figur~le 4.6-lneeds clarification. The period of record on which this is based needs to be specified. In addition, the wind direction frequencies in tabular form or in the form of a~lwind rose upon which this extrapolated wind rose vias based should be documented. The adjusted wind rose appears to~lindicate a large percentage of crossvalley flow. The rationale and limitations of this extrapolation should be inq~uded in' the application. Wind rose data are particularly of interest in evaluating air quality impacts. Specific location oaf the monitoring site should be identified on a figure. ~~ Although the initiation of an onsite meteorological monitoring program would not be requested to satisfy the intent of OSM regulations, available onsite meteorological data should be included in the application. Specifically wind speed, wind direction and atmospheric stability data derived from (iif available) should be documented if one or more ~iquarters are available in the data set. ~' 21.
