Can you provide an update on air monitoring that has occurred since April 2018 and what will happen during the rebuild process?
In addition to monitoring conducted by the Environmental Protection Agency, the Refinery collected more than 208 million air quality readings in the community and at the refinery from April 26 through November 16, 2018. All community monitoring indicated concentrations below health-based thresholds.
Additional site and/or community monitoring will be re-initiated during the rebuild as determined by activities on site and in accordance with state and federal regulations.
Community feedback on the rebuild, including options for community safety improvements outside the refinery fenceline can be sent to email@example.com.
Are there any changes to the wastewater treatment program specifically for PFAS?
First responders used firefighting foam while fighting the fire and some of the foam contained Per- and Polyfluoroalkyl Substances (collectively known as PFAS). To treat the PFAS, the Refinery installed an additional onsite treatment system downstream of the existing wastewater treatment plant. This treatment has proven to be effective in removing PFAS in the water prior to discharge.
Can you comment on the PFAS contamination of Newton Creek?
Water samples collected from Newton Creek post-incident are comparable to baseline samples collected prior to the incident under normal operating conditions where there are trace amounts of PFAS.
Will the refinery be sending its wastewater to the City of Superior's publicly owned treatment works and stop discharging to Newton Creek? If so, when will that occur?
The Refinery is committed to sending its wastewater to the City's water treatment facility following its on-site treatment at the refinery's wastewater treatment plant. The date of this process change has not been determined.
What are you doing to protect wildlife in the vicinity of the refinery?
Protections and deterrents for wildlife, including fencing, flagging, canine patrols and laser stations are currently in place or immediately available. Wildlife continues to be monitored on-site to ensure current systems are effective at protecting wildlife. Enhancements will be made if deemed appropriate.
