Chadbury Place Development

The City of Troy has been working with Mondrian Properties (developer), Pamar Enterprises (contractor), Testing Engineers & Consultants (TEC) and the Michigan Department of Environment, Great Lakes and Energy (EGLE) to investigate and provide solutions to the “slime” observed on the site of the Chadbury Place development on the south side of E Long Lake Rd between John R Rd and Dequindre Rd. 

Soil samples were collected from the site on Thursday, August 20, 2020.  The affected soil was treated with lime on Friday, August 21, 2020 to help dry the soil and reduce the odor.  The City received the Data Summary and Laboratory Report on Monday, August 24, 2020. 

Two compounds were detected: creosol and toluene.
Creosol is a naturally occurring compound and there are no cleanup criteria in state law. The concentration of toluene was not significant and does not appear to pose a risk to the neighboring homes (approximately 45 feet to south). However, the concentration of toluene exceeds Michigan EGLE residential cleanup criteria for new homes to be constructed on the site. Accordingly, the affected soil will be removed from the site.

The affected soil will be treated with lime again on Wednesday, August 26, 2020 so it can be dried and removed within the next two (2) weeks. City staff will be on site to observe the work and coordinate with EGLE as necessary.

September 4, 2020 Update
 
 
The City of Troy has been working with Mondrian Properties (developer), Pamar Enterprises (contractor), Testing Engineers & Consultants (TEC), Brighton Analytical (BA), and the Michigan Department of Environment, Great Lakes and Energy (EGLE) to investigate and provide solutions to the “slime” observed on the site of the Chadbury Place development on the south side of E Long Lake Rd between John R Rd and Dequindre Rd.
 
Pamar Enterprises and Mondrian Properties retained Brighton Analytical to sample the material on the Chadbury Place site on August 26, 2020.  Typical test procedures take 5 business day. Brighton Analytical provided the attached test results to Pamar Enterprises on September 2, 2020. The results of the test indicate that there were no apparent contaminants above a detectable level.
 
Pamar Enterprises treated the area with lime, after the test results were received, on September 2, 2020 to reduce the odor that some residents had noted. Based on the test results, the material can be transported off-site to a regular landfill. Pamar Enterprises was on site to begin removal operations on September 3, 2020.  Lime is on site to stabilize wet material as necessary so that it can be removed.
 
Work will be stopped around 3PM September 4, 2020, due to the Labor Day Holiday weekend. Pamar expects to be back on site on Tuesday, September 8, 2020 and Wednesday, September 9, 2020, to complete the removal operations. Clean fill is being placed in the area where pond soils have been removed to cap the area for the weekend. The City of Troy has inspection on the site to verify that the material is removed.
