Acquisition Financing of Occidental's Wyoming Trona Assets

Winston & Strawn LLP represented a group of institutional investors purchasing privately placed notes issued by a subsidiary of Orion Resource Partners (“Orion”) in connection with Orion’s acquisition of certain producing trona mineral interests located in Sweetwater County, Wyoming from Occidental Petroleum Corp. (“Oxy,” NYSE: OXY). The transaction, which is expected to close in the fourth quarter of 2020, has a footprint of approximately 275,000 net trona mineral acres located across the world’s largest known trona mineral deposit. Trona is a mineral that is actively mined and used to make soda ash, the principal ingredient in baking soda, global glass manufacturing, pollution control systems, as well as other critical chemical applications. The acquisition financing served to support Orion’s broader acquisition of Oxy’s land grant assets located across Wyoming, Colorado, and Utah, that includes 4.5M mineral acres (including coal and oil and gas mineral interests) and 1M surface fee acres, making it one of the largest single land purchases in the United States in the past 70 years....Read more

EPA Shifts Regulatory Strategy on Power Plants

The EPA announced on June 11 its intention to repeal three rules under the Clean Air Act that regulate emissions from power plants. This move comes as part of the Trump Administration’s broad energy and regulatory policy shift aimed at expanding domestic energy production, reducing regulatory burdens, and ensuring affordable, reliable energy, as outlined in Executive Order 14154— “Unleashing American Energy” and Executive Order 14156— “Declaring a National Energy Emergency” issued in January 2025. Critics of the Administration’s strategy fear that adverse impacts may result to the energy industry, public health, and the climate.
