The Peoria City County Landfill Committee met their usual third Wednesday, May 16, at 3 pm, in Room 404 at Peoria City Hall.
Public comment included a request for explanation of some of the chemicals showing up in groundwater monitoring and how some are determined not to be not site related and others have continued testing.
Committee Chair Steve Morris asked that Foth engineering address the questions during their Groundwater Update report. Some test wells are affected by migrating landfill gasses. Other things that happen are contaminants that are from the coal mining done at the site before it became a landfill or testing at the lab. If a level of concern is detected, there is a time-frame for follow-up testing, which often shows no further action is needed. If levels remain of concern, the next step is a determination of the source and assessment monitoring is done. The testing looks for a statistically significant change as they want to know if the landfill is affecting groundwater.
The annual Landfill Gases report showed 98,000 metric tons of CO2 equivalent releases for 2017 which is mostly in the form of methane. This is approximately a 16% increase over 2016 and is due in most part to fugitive emissions from areas where garbage is placed that do not yet have a landfill gas collection system.
Scott Reese, City of Peoria Public Works, stated that due to an agreement related to the recently approved City waste hauling contract, PDC would be paying $450,000 up front ahead of schedule as it was originally part of the new Landfill #3 contract with PDC, who will build and operate the next landfill.
The contract for engineering services with Foth was renewed for 3 years based on their excellent work in meeting all performance requirements and staying in budget. The next meeting will be June 20th.
