Updated: September 11, 2019

Background

MAP Escanaba This site is located on the Little Bay de Noc shoreline and was a bulk fuel storage facility that supplied jet fuel to the former K.I. Sawyer Air Force Base in Gwinn via pipeline. The PFAS contamination at the site first came to the Michigan Department of Environment, Great Lakes, and Energy (EGLE)'s attention in April 2014.

Recent Accomplishments

  • EGLE has received the Air Force’s May 17, 2019, Draft Final, Second Five-Year Review Report. In the report, the Air Force stated that they will not consider Michigan criteria for PFOA and PFOS as part of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Five-Year Review process protectiveness analysis.

Next Steps

  • EGLE is evaluating next steps, however, the United States Air Force is without funds for this site.
  • Land use control inspection is scheduled for October 17, 2019.
