:: Mr. Steve Self -2- March 8, 1984 7~ A copy of the BLM spring and seep survey and a map delineating all springs and seeps within one mile of the permit area must be provided. A year's baseline collection is required on the flows and water quality of O/L springs within the permit and adjacent areas to establish seasonal fluctuations. b/ 8. ~he loc~ o~f ~heCte~ e~rigated with water from Grass Valley BBL Reservoir/Harvey Gap Oralnage and the Farmer's Irrigation Company Ditch must be depicted. 9. Rule 2.04.9(1)(b) requires soils analysis of each soil horizon for each ~ ~~( soil type to be affected. At a minimum, Eastslde should obtain samples by horizon from at least one soli pit in each area to be disturbed (i.e.: refuse ~+-~ area and facilities area). For previously disturbed areas where surface soils 0~~ have been altered, information should be collected by 6" Increments to bedrock or a total depth of 60". Analyses should include texture, EC, SAR, pH, and O.M. 10. The application must include a soils map at a scale of at least 1:6000 ~„~~ which depicts sample location and stripping depths, as required by Rule ~„g 2.04.9(1)(c). ~('Ni'~,_R 11. The areas to be disturbed at Eastslde have been previously disturbed by pre-law mining, and as such, the revegetation success criteria of Rule 4.15.10 apply. Rule 4.15.10 requires that ground cover be not less than the cover that existed before redlsturbance, not be less than can be supported by soil material 1n the reaffected area, and be adequate to control erosion. The applicant's baseline vegetation inventory, which will be used to develop the revegetation succ~andard 1s deficient in the following regards: Sc`'o'1 s~~~~ No data or descrip~ regarding existing vegetation cover 1s provided for the proposed waste pile area or the proposed facilities area near the ,)unction of the county road and the existing Eastslde access road. Information is provided fora "Proposed mine west of Harvey Gap", but that proposed mine is not discussed 1n other portions of the application. b. Only 1 cover transect per vegetation type was taken in undisturbed areas. As a result, no statistical confidence can be associated with the estimates. In order to complete the vegetation portion of the application, the following information will need to be submitted. a. A narrative description and ocular estimation of vegetation cover 1n UCH areas to be affected by the proposed waste pile and the proposed facilities area. / b. A plan for collecting statistically adequate vegetation cover data ~ (L for use 1n revegetation success comparisons.
