The Montana Department of Environmental Quality published Sept. 22 a draft air quality permit and draft environmental assessment for Calumet Specialty Products Partners LP’s renewable diesel conversion project at its refinery in Great Falls, Montana.

According to the state DEQ, analysis of the proposed project shows it would not violate ambient air-quality standards.

The 15-day public comment period closes Oct. 7. To submit comment or to view the draft permit and draft environmental assessment, click here.
