MPCA seeks comments on proposed projects at Flint Hills’ Rosemount facility

Contact: Mary Connor, 651-757-2629

Flint Hills Resources Pine Bend LLC, in Rosemount, a crude-oil processing plant, is proposing a collection of projects designed to increase the facility’s energy efficiency, reduce its air emissions, and improve its processing capabilities. The projects include:

  • Replacing two pieces of equipment known as coking process units with a single modern unit and a gas-recovery unit. Replacing the two existing cokers with a new one will decrease the facility’s nitrogen oxide emissions by more than 350 tons per year.  
  • Installing new and improving existing equipment to produce more ultra-low sulfur diesel fuel.
  • Modifying equipment to allow the facility to increase its production of gasoline, diesel fuel, and other products.

The Minnesota Pollution Control Agency has prepared an environmental assessment worksheet on the proposed facility changes to describe the project and outline its potential impact on the environment. The EAW details the site location, nearby bodies of water and groundwater, soil types, air and odor emissions, noise concerns, and more. The EAW is available on the MPCA's EAW webpage.

Comments on the environmental assessment worksheet must be submitted in writing by 4:30 p.m. on Oct. 26, 2016 to Charles Peterson (651-757-2856) at the Minnesota Pollution Control Agency, 520 Lafayette Road N., St. Paul, MN 55155-4194.
