Questions for the City of Peoria

The city of Peoria held a town hall on February 27th, 2025, but didn't allow the attendees to ask questions of substance. The forum allowed you 2 minutes to type questions of up to 200 characters Into a poorly designed app. I am posting my questions In hopes that our council representative, Matt Bullock, will answer these questions to help the residents of Peoria, AZ, better understand the upsides and risks of this project. On the surface, there are no benefits to the residents of Peoria and plenty of risks for pollution, noise, and water supply contamination with forever chemicals known as PFAS.  

1. What are the expected expenses, tax revenue, and ROI of the Amkor project for the City of Peoria, AZ, over the next 10 years beginning in 2025? Exclusive of Job creation.

2. According to the media, the city has agreed to split the costs of treating Amkor’s wastewater. What is the estimated total cost to the citizens?

3. The city is requiring Amkor to return 80% of the water used back into the system. Will Amkor’s effluent water be cleaned of all PFAS and other chemicals before being sent to the Jomax treatment facility? (this was not addressed explicitly during their town hall on January 8th, 2025. They just mentioned organic and inorganic solids.)

   • Who will monitor this?

   • It shouldn’t just be Amkor monitoring itself; there should be external continuous monitoring by the city or state. Not just Amkor. What are the plans?

   • Amkor should pay for real-time, 24/7 wastewater monitoring systems installed after their pre-treatment system to ensure no PFAS are being passed into city wastewater. Is this being considered?

   • If any detectable PFAS or other harmful chemicals are released, Amkor should cease operations until the issue is resolved. What will be the protocol?

4. Where/how will the solid waste by-products, including PFAS and other chemicals that are a result of cleaning the water, be disposed of?

   • At this time, the EPA does not have any regulatory requirements for the treatment, destruction, and disposal of water treatment residuals that contain only PFAS. They do have interim guidance that recommends “safe destruction and disposal and/or using a hazardous waste landfill. What techniques will Amkor deploy to ensure safe destruction and disposal?

   • Are they planning on incinerating PFAS contaminated materials on-site?

   • If they are going to dispose of PFAS in a Hazardous waste landfill, where is this landfill located?

5. Amkor will have an atmospheric management system to clean the air in and discharge it from the facility.

   • Will there be continuous monitoring of this system by external parties?, and will they cease operations if these systems malfunction or detectable PFAS or other contaminants are released? What will be the protocol?
