This appendix includes information on surface disturbance and reasonable foreseeable actions within the Planning Area. Table T-1 provides projected acres of surface disturbance by resource. Table T-2 provides foreseeable development project assumptions by resource; the projected surface disturbances in Table T-1 are based on the project assumptions in Table T-2.

| 1Based on the Reasonable Foreseeable Development for Geothermal (BLM 2009a), development is unlikely and would only occur on previously disturbed areas. 2Acres disturbed by mechanical fuels treatment and prescribed fire will naturally be reclaimed within 5 years. 3Includes range enhancements and other wildlife habitat restoration actions. 4Assumes 10 percent of the BLM actions acreages. 5Surface disturbance activities resulting from invasive species projects will be naturally reclaimed within 5 years. Therefore long-term disturbance from BLM actions will be zero. 6Based upon 58 percent BLM-administered surface; 42 percent private and state trust lands. 7Actions would likely be mostly oil and gas related, including CO2 and energy pipelines. 8Approximately 50 percent of roads would be oil and gas related (based on the Reasonable Foreseeable Development Scenario for Oil and Gas [BLM 2009b]), with the rest coming from local demand. 920 sites at 0.5 acre each. 10Actions would likely be mostly oil and gas related.

| Assumptions | All BLM-administered mineral estate except in areas specifically withdrawn or closed to mineral entry would remain open for mining claim location, and exploration and development of locatable minerals. | Large acreages in ACECs and other special management areas are proposed for withdrawal from mineral entry under the Mining Laws. However, this would not significantly limit opportunities to explore for and develop locatable minerals, as many areas in the Planning Area where locatable minerals occur would remain open to locatable mineral entry. | Same as assumption under Alternative A, except less acreage would be proposed for withdrawal from mineral entry under the Mining Laws. | Same as assumption under Alternative A, except less acreage would be proposed for withdrawal from mineral entry under the Mining Laws. |

| Assumptions | Assumes 700 acres/year new mining disturbance in the CYFO for bentonite and gypsum and 300 acres/year new mining disturbance in the WFO for bentonite. New closures or withdrawals would not take place in areas where there are active bentonite, gypsum, or uranium mining claims. Assumes no new surface disturbance for uranium development. | |||
