hayland production, are included in Attachment 2.05.4(2)(E)-A, of the permit application. Irrigated hayland production success will be demonstrated when the production mean based on sampling is not less than 90% of 1.84 tons per acre, with 90% statistical confidence. Alternatively, success will be demonstrated when production based on total harvest (1~` cutting) is not less than 90% of 1.84 tons per acre. The success standazd for irrigated pasture areas is a technical standard based on the same combination of landowner estimates, production records, and NRCS evaluation as described for irrigated hayland. The standard for irrigated pasture is 1.5 tons per acre/year, for 1s` cutting production. Irrigated production success will be demonstrated when the production mean based on sampling is not less than 90% of 1.5 tons/acre/yeaz, with 90% statistical confidence. Alternatively, success will be demonstrated when production based on total harvest (1 ~` cutting) is not less than 90% of 1.5 tons per acre. The success standazd for dryland pasture areas in the New Horizon Mine 2 area will be based on comparison to herbaceous production in the dryland pasture reference area, which was approved in 2000, in conjunction with PR-O5. Success will be demonstrated when production based on random sampling within the bond release parcel is not Less than 90% of the dryland pasture reference azea mean, with 90% statistical confidence. The success standazd requirements for species diversity, seasonal vaziety, and woody plant density on all three proposed end land use types will be waived since post-mining land uses will be pasture and hayland. The Division proposes to approve these standards. F. The Division has already approved of the reference azea used for the New Horizon 1 area which the applicant has selected based on the requirements of Rule 4.15.7(3). A new reference azea, established and initially sampled in 1999, is approved for determination of revegetation success for New Horizon 2 dryland pasture reclaimed areas, in association with PR-O5. G. The reference aeeas will be utilized to determine revegetation success in a manner which the Division finds acceptable 4.15.7(4)(a). VIII. Post-mining Land Use A. The land use within the New Horizon Mine 1 area is predominantly wildlife habitat. The remaining azea has been designated as rangeland and dryland pasture. is
