MMEX Resources Corp. received on February 18, 2022, the approval of the Texas Commission on Environmental Quality to build its Pecos County, West Texas UltraClean Refinery project. As noted in MMEX's July 29, 2021 announcement, the company was able to expand the ultraclean fuels product flexibility with the facility being slated to produce finished transportation grade ultra-low sulfur diesel; 87 Regular, 87 Clear, and 93 Premium grades of gasoline, readily available to market on Interstate 10, the "transcontinental" highway traveling thru eight states from coast to coast.

Rail capacity is expected to allow to reach Texas Gulf Coast and western U.S. markets to take advantage of clean fuels mandates and price advantages.
