Lansing Area Environmental Updates
April 20, 2021
RACER Conducting Additional PFAS Assessments in Response to Updated Cleanup Criteria
RACER Trust will soon begin to assess the potential presence of PFAS in groundwater north and east of the property boundary for the former GM Lansing Plant 6 property. This assessment is in response to the Michigan Department of Environment, Great Lakes, and Energy’s (EGLE) December 2020 update of groundwater cleanup criteria.
There remains no known exposure pathways for area residents associated with the site contaminants.
After coordination with EGLE, which oversees RACER’s environmental work at the former GM properties in Lansing, Lansing Township and Delta Township, approximately 18 commercial and residential property owners in the assessment area will be receiving a letter from RACER with information regarding how groundwater containing PFAS relates to their property. There is no indication that any property owner is using groundwater; drinking water is supplied by the Lansing Board of Water & Light.
Characterization of PFAS is ongoing to the north, east, and south of Plant 6. Interim actions for PFAS include storm sewer modifications on Plants 2, 3, and 6 to eliminate groundwater containing PFAS from infiltrating into and then discharging off-site through the storm sewers. RACER will also continue to monitor potential soil vapor intrusion (VI) to indoor air in the northeast portion of Plant 6 and the adjacent off-site area.
Finally, results of routine sampling show that the biosparge systems installed at the former Plant 2 and Plant 3 properties are achieving the short-term objective of reducing 1,4-dioxane concentrations along the core of the weathered bedrock plume.
More details are available in the quarterly report RACER submitted to EGLE, which can be viewed and downloaded by clicking the link below.

Monitoring Wells Being Installed to Evaluate PFAS Beyond Plant 6 Site
RACER Trust will install monitoring wells in the Michigan Avenue right-of-way, south of the former GM Plant 6 property, to gather additional data on the potential presence of PFAS beyond the Plant 6 property line. The work is being completed under the oversight of the Michigan Department of Environment, Great Lakes, and Energy.
The work along Michigan Avenue is expected to begin on, or about, March 10 and take two or three days to complete. Every effort will be made to ensure the public’s safety during the work and to minimize disturbance to traffic and landscaping.
If PFAS are found in shallow groundwater south of the Plant 6 boundary, additional investigation in those areas will likely be necessary later this year. However, it is emphasized that PFAS will not impact area residents since concentrations are expected to be low and shallow groundwater is not a source for drinking water. Drinking water is provided by the Lansing Board of Water and Light. Furthermore, it is highly unlikely that the presence of PFAS would impact activities at Sexton High School.

RACER Updates the Community on Environmental Activities at Lansing-area Properties
RACER Trust has prepared a comprehensive quarterly overview of ongoing and planned environmental activities at its former GM properties in the Lansing area.
The overview, which summarizes work conducted between July and September, is available at the link below.
RACER’s environmental activities are carried out under the oversight of the Michigan Department of Environment, Great Lakes and Energy, which also received a copy of the quarterly overview.
There are no known impacts to any drinking water source or public exposure to any contaminants associated with the former GM operations. We’re continuing to address 1,4-dioxane impacts to ground water 60 to 75 feet below the surface, and have made storm sewer modifications on the property to eliminate PFAS discharges.
In addition, we have assessed soil and groundwater conditions near the property and found no evidence to suggest gasses in the soil are causing any indoor impacts. Additional assessment and monitoring will continue to verify conditions do not change over time.
More details about these and other activities can be found in the quarterly overview.

RACER conducting off-site sampling in Lansing; Q2 summary of activities available
Please click the link below for a summary report of RACER’s second-quarter 2020 environmental activities in Lansing.
RACER Trust has begun collecting soil and groundwater samples in the area of Stanley Street and Osborn Road, just east of the former GM Lansing Plant 6 property, to determine if volatile organic compounds (VOCs) found at the property are present and creating the potential for vapor intrusion. We expect to complete these activities this week.
This work, and all environmental activities at the former GM Lansing properties, is being conducted under the oversight of the Michigan Department of Environment, Great Lakes and Energy (EGLE). RACER will complete a thorough evaluation of the data, including potential risks associated with any VOCs detected in groundwater east of the former Plant 6, and provide that evaluation to EGLE for review. We also will summarize the information and share it publicly on the RACER website.
There are no known exposures to VOCs east of the Plant 6 property. The concentrations are expected to be low and the shallow groundwater is not used as a source of drinking water. Water is supplied to the businesses and residences in the area by the Lansing Board of Water and Light.

RACER Trust Submits First Quarterly Report of 2020 On Environmental Activities at Lansing-Area Properties
RACER Trust has submitted its First Quarter 2020 Quarterly Progress Report for environmental activities at its former GM Lansing-area properties to the Michigan Department of Environment, Great Lakes and Energy. A link to the report can be found below.
Highlights of the report include:
- There remains no known exposure pathways for area residents associated with contaminants at the properties (former GM Lansing plants 2, 3 and 6).
- The biosparge treatment system to address 1,4-dioxane impacts at the Plant 3 property is working as designed. Sampling data indicate a 97% reduction in 1,4-dioxane concentrations within the system’s radius of influence.
- A biosparge system for the Plant 2 property, also designed to address 1,4-dioxane impacts, is scheduled to come online in July or August.
- Modifications to storm sewers at Plant 2 resulted in a 75% reduction in PFOS concentrations at the Plant 2 outfall.
- No samples exceeded surface-water standards for PFOS at Plant 6, a result of modifications to storm sewers that were completed in the fourth quarter of 2019.
The report includes a schedule of upcoming activities. Please note the timing of several activities is likely to be impacted by the current Stay-Home/Stay-In executive order.
RACER Trust is continuing to carry out its environmental obligations — including preparation of remedial action plans, maintenance and operation of remediation equipment, and timely collection and reporting of data to federal and state regulatory agencies — during the COVID-19 emergency. RACER personnel and contractors are taking all appropriate precautions to protect themselves and our communities from the further spread of COVID-19 while carrying out environmental obligations.

Summary of Quarterly Environmental Activities, April-June 2019
A recap of environmental activities for the April-June quarter at the former GM Lansing Plants 2, 3 and 6 has been submitted to the Michigan Department of Environment, Great Lakes and Energy (EGLE) and can be viewed by clicking the link below.
RACER is proceeding with implementation of an EGLE-approved plan to address 1,4-dioxane impacts to groundwater using a biosparge treatment method. RACER’s goal is to have the biosparge system fully operational in 2020. Biosparge works by stimulating the growth of organisms that feed on and degrade the chemical in the groundwater.
RACER continues to investigate PFAS discovered in groundwater at the former GM Lansing properties and east of the properties. There is no exposure to or known use of the impacted groundwater.
RACER also is investigating PFAS discovered in storm sewers that are present on the former GM properties and working with EGLE to implement remedial plans at the properties.
RACER to Investigate PFAS Near Lansing Plant 6 Property
RACER Trust will conduct further off-site sampling of shallow groundwater at two location east of the former Lansing Plant 6 property during the first week of May. The purpose of the work is to evaluate if PFAS impacts have migrated off-site in groundwater east of Plant 6. Please click below to view and download a fact sheet about the upcoming work.

Results of Sampling, Former Lansing Plants 2 and 6
RACER Trust’s environmental consultant collected storm water samples from manholes at two locations where storm water leaves the former Lansing Plant 2 Property and at five off-site storm sewer manholes in Osborne and Verlinden Streets near where storm water leaves the former Lansing Plant 6 Property. These samples were collected after initial sampling indicated the presence of per- and polyfluoroalkyl substances (PFAS) in on-site groundwater in excess of the State of Michigan surface water quality standard for PFOS. The results have been submitted to the Michigan Department of Environment, Great Lakes, and Energy (EGLE, formerly the Michigan Department Environmental Quality), which is overseeing RACER’s work at its Lansing-area properties. PFOS was detected above the state standard at one of the two storm water sampling locations at Plant 2. Additional sampling of the Plant 2 storm sewer system was completed on January 26, 2019, to obtain additional data to better isolate potential contributions of PFOS in storm water. This data will be used to help identify and evaluate possible options to mitigate discharge of PFOS to the Ingham County and City of Lansing sewers located north of Plant 2.
Additional work at Plant 6 included installation and sampling of temporary monitoring wells and soil borings as well as collection of samples from adjacent rights-of-way. PFOS and PFOA exceed drinking water criteria at several locations along the eastern property boundary of Plant 6, as well as in the southwest portion of the Site, near a former rinse water cistern. Additional sampling is proposed to complete delineation near the property boundaries.
RACER Trust also has submitted to MDEQ a work plan to facilitate biodegradation in the lower 1,4-dioxane plume that extends from the Plant 3 “coliseum” area to the south-central portion of Plant 2.
The details provided in the work plan are subject to updates as MDEQ completes its review and the design work progresses.
Proposed 1,4-dioxane Remedial Approach
After extensive sampling of Site conditions, testing the approach at the Site and reviews with the Michigan Department of Environmental Quality, RACER Trust is proposing to remediate the lower 1,4-dioxane plume at the former Lansing Plants 2 & 3 using a technology called biosparging, a technique that involves bubbling air through the groundwater to stimulate biological activity. In this case, RACER Trust is recommending the safe, controlled injection of an air/propane mixture and nutrients into the subsurface to stimulate the activity of microorganisms, which will biodegrade 1,4-dioxane. 1,4-dioxane degrades to non-toxic carbon dioxide and water. The activity, if approved, will be comprehensively monitored to track progress. The technology would be implemented in 2019 and 2020 and is expected to operate 10 or more years.
RACER to Conduct Additional Activities in Lansing
RACER Trust will install monitoring wells, complete additional soil borings and collect water samples from storm sewers, among other activities, in November and December near its properties in Lansing. A detailed fact sheet can be viewed and downloaded from the link below.
