Cherry Capital Airport’s Environmental Commitment: PFAS

Cherry Capital Airport’s Environmental Commitment: PFAS

Cherry Capital Airport is committed to working with all partners involved to ensure the health and safety of our community continues to be a top priority. At the airport, we have taken steps to reduce the use of firefighting foam, while embarking on a long-term testing process of the airport’s property. We will continue to work side by side with the Michigan Department of Transportation (MDOT) and the Michigan Department of Environment, Great Lakes, and Energy (EGLE) throughout this testing process, and are dedicated to working with all other parties involved.

What is PFAS and why does it occur?

PFAS, or Per- and polyfluoroalkyl substance, are a group of man-made chemicals used in many industries across the globe and have been in use in the United States since the 1940s, though most widely used in industrial processes and firefighting foams by the military, airports and fire and rescue agencies.

After many decades of broad use, PFAS can be found in food, household items, workplaces, drinking water, wildlife, and in blood and tissue samples from people. PFAS’ unique properties slow its chemical breakdown, resulting in PFAS accumulating over time in soil and groundwater.

At airports, PFAS are often found in aqueous film-forming foam (AFFF), which airports deploy to quell and suppress petroleum-based fires. Because PFAS in AFFF effectively suppresses fires, the chemical has been used consistently over the years to battle fires at airports across the country as well as during testing and training at airports.

Testing and Community Protection

In January of 2018, groundwater criteria for PFOA and PFOS, two types of PFAS substances prevalent in aqueous film-forming foam (AFFF), were established by EGLE under Part 201 of the Natural Resources and Environmental Protection Act (NREPA) consistent with the United States Environmental Protection Agency health advisory criterion levels not to exceed at 70 ppt (parts per trillion) for the combined concentrations of PFOA and PFOS. In August of 2020, the State of Michigan developed more stringent standards in requiring that groundwater concentrations not exceed 8 ppt for PFOA and 16 ppt for PFOS. In conjunction with the establishment of these stricter criteria, a concerted effort has been made by EGLE to identify any locations where the use of AFFF has been employed, including airports like Cherry Capital.

To the north of the airport is the Pine Grove neighborhood, where a number of residents were still utilizing wells for their everyday drinking water needs. Due to the proximity of these wells to the airport, EGLE reached out to Cherry Capital Airport to request information regarding its use of firefighting foam. Cherry Capital Airport is committed to working side by side with EGLE and MDOT during this process to ensure that further testing is completed to support the initiative of keeping our community safe and healthy.

Why does Cherry Capital Airport care about PFAS?

Why TVC Cares about PFASSince the 1970s, aqueous film-forming foam (AFFF), which contains PFAS, has been stored and used at the Cherry Capital Airport in firefighting foam in compliance with Federal Aviation Administration (FAA) mandates. AFFF has been considered the most effective method of fighting jet fuel-based fires since its development by the U.S. Navy in the 1960s. The FAA has long required annual firefighting equipment testing, which has resulted in discharges of AFFF onto the tarmac and immediately adjacent areas on airport property.

Although AFFF containing PFAS substances are still being utilized by airports across the country until a more environmentally friendly solution is found, the FAA does allow for an exemption to not dispense AFFF during airport testing of firefighting equipment. To help support this effort, in March of 2019, the Michigan Aeronautics Commission (MAC) approved a grant program that provided each commercial service airport in Michigan with nearly $25,000 to acquire environmentally conscious firefighting foam testing devices. These types of devices connect to existing firefighting trucks to ensure proper foam proportioning without the need to dispense any firefighting foam concentrate, eliminating a potential pathway for PFAS to enter the environment while ensuring the readiness of airport firefighting equipment. In September of 2019, Cherry Capital Airport took delivery of one of these units.

A concerted effort has also been put forth at Cherry Capital Airport related to the review of its standard operating procedures related to AFFF, to ensure there are safe and environmentally effective handling, storage, and disposal procedures in place.

The FAA Reauthorization Act of 2018 directed the Federal Aviation Administration to eliminate the requirement for the use of AFFF at airports, providing a 3-year timeline to research alternatives that would be deemed just as effective. Approved alternatives were originally expected to be released by the end of 2021. However, the FAA has encountered delays in conducting its research due to the impacts of COVID-19 and as a result, completion of this project could potentially extend into 2022.

Cherry Capital Airport PFAS Response Next Steps

The NRAA has been awarded a second grant by EGLE to undertake another phase of an investigation program. Vertical aquifer profile testing on and off-airport is anticipated during 2023.

Collaborative Efforts:

Cherry Capital Airport is dedicated to assisting EGLE with any necessary PFAS remediation efforts and is committed to being a supportive and transparent partner in order to protect the area we call home. To support this endeavor, Cherry Capital Airport has taken proactive steps in communicating with various agencies and local representatives in an effort to aid with obtaining funds to cover the cost of connecting new water lines to those residents whose wells were impacted by PFAS.

These included:

  • East Bay Township – Cherry Capital Airport offered to assist the township in applying for Consolidation and Contamination Risk Reduction (C2R2) grant funding, made available through the State of Michigan for drinking water system remediation efforts.
  • USDA Rural Development – Worked with its director, Jason Allen, on potential funding options through the USDA that may apply. Information provided to EGLE in November of 2020.
  • U.S. Senator Gary Peters’ Office – Inquiry regarding the availability of any additional funding options through the federal government that could assist with covering the cost of the project.
  • State Senator Wayne Schmidt – Inquiry regarding the availability of any additional funding options through the State of Michigan that could assist with covering the cost of the project.
  • Federal Aviation Administration (FAA) – Inquiry as to the availability of any federal funds/grants.

As additional testing is completed and results are determined, we will continue to partner with federal, state and local authorities to ensure a long-term solution is reached. These organizations include:

  • East Bay Township
  • Grand Traverse County Commission
  • Grand Traverse Health Department
  • Michigan Department of Environment, Great Lakes and Energy (EGLE)
  • Michigan Department of Health and Human Services (MDHHS)
  • Michigan PFAS Action Response Team (MPART)
  • Federal Aviation Administration (FAA)
  • Michigan Department of Transportation (MDOT)
  • USDA Rural Development – Michigan
  • American Association of Airport Executives (AAAE)
  • Environmental Protection Agency (EPA)
