Reclamation Reporting The Annual Reclamation Report will be submitted by March 30th of each year and will report those items required by 2.04.13(1). Additionally, the following information will be included: • Annual herbicide applications and weed and pest control measures • Summary report on livestock grazing management, pasture use, estimated AUMs and forage utilization on reclaimed lands • Results of sediment pond surveys (when conducted) Reveutation Chronology Approximately 3.1 acres were seeded in year 2002 and 55.7 acres were seeded in 2003, with remaining 207.9 seeded prior to 2000. See Map 2.05-M2, Revegetation Chronology, for seeding locations by year. 2.05A(2)(e)(vi) Determining Revegetation Success Revegetation success will be determined based on the results of revegetation monitoring in accordance with the applicable Sections of 4.15.7, Determining Revegetation Success - General Requirements and Standards, 4.15.8, Revegetation Success Criteria, and 4.15.11, Revegetation Sampling Methods and Statistical Demonstrations for Revegetation Success. At the time of revegetation success evaluations and periodically during monitoring, quantitative vegetation data will be collected from the mountain brush and sagebrush reference areas established for the Seneca II mine. These reference areas were established to represent the primary native communities in and around the Seneca II Mine. The reference area standard will be determined by weight averaging the cover or production data from the two reference areas based on 83 % of the original extent of mountain brush and 17 % of the original extent of sagebrush on premine lands affected by mining. Revegetation success will comply with Section 4.15.11 and will be evaluated based on the parameters of cover, production, diversity, and woody plant density by comparing statistically adequate quantitative data from the reclaimed area and vegetation reference areas or approved technical standards. The plan presented in Appendix 13-13 "Vegetation Evaluation Procedures for Testing Reclamation Adequacy for Phase III Bond Release" remains in effect, with the exception of certain clarifications presented in this Section 2.05.4(2)(e)(vi) of Volume 14. Sampling and statistical methods and success criteria for vegetation cover for Phase II bond release are consistent with the methods and criteria described for Phase III bond release, with the exception that vegetation cover success for Phase II release requires only a single year. Note that vegetation sampling for bond release success demonstration for the Seneca II permit area will be conducted completely independent of vegetation sampling for bond release success demonstration in the adjacent Sage Creek permit area (which was originally a part of the Seneca II permit area). This means that any Phase II or Phase III bond release applications for the Seneca II permit area will be supported by statistically PR-02 2.05.4-2 11/10
