The U.S. Bureau of Land Management (BLM) in Utah is planning to offer 75 oil and gas parcels within 94,000 acres in Duchesne, Uintah and Emery counties in an online December quarterly lease sale. BLM said the leases would contain stipulations and best-management practices aimed at addressing air quality and water resources and ensuring the “safe and environmentally responsible” development. BLM also may modify the stipulations to accommodate site-specific resources. Last year, leasing on BLM lands in Utah contributed $1.7 billion to the economy, supporting 9,700 jobs, according to the federal agency.
