If interest arises, the BLM may allow coal exploration subject to the regulations at 43 CFR 3410 and subject to Appendix H guidance to mitigate surface-disturbing activities. Closing large areas to mineral leasing or applying NSO restrictions on large areas may adversely affect potential coal leasing in the Planning Area if demand were to arise. Major and moderate constraints on mineral leasing, geophysical exploration, and minerals development also would adversely impact potential future coal leasing.
