Update on Cleanup Work – Excavation Continues at Former Tannery

Wolverine is currently conducting cleanup work at the site of its former tannery in Rockford. First, we cleared vegetation, constructed temporary access roads, detoured the White Pine Trail, and staged equipment and supplies. Then, we began installing silt curtains and cofferdams in the Rogue River, before starting to excavate. This work is described in more detail in posts here and here.

Included at the end of this post and at this link are updated maps showing the excavation areas in orange and turquoise. The areas located south of Rum Creek are labeled S1 through S7, and those located north of Rum Creek are labeled N1 and N2.

To help track the work, here is a chart showing the material we anticipate excavating from each area, and the current status of our activities:

Area Material Status
S1 Soil Excavation in progress
S2 Soil Excavation in progress
S3 Soil Excavation in progress
S4 Soil Excavation in progress
S5 Sediment Cofferdam installed; excavation in progress
S6 Sediment Excavation complete and backfilled; cofferdam removed
S7 Soil Cofferdam installed; excavation in progress
N1 Soil, Leather Scraps, Hides Cofferdam installation in progress; excavation anticipated to start next week
N2 Soil, Leather Scraps, Hides Cofferdam being installed this week; excavation anticipated to start in mid-November

Removed material is being taken to licensed landfills in Ohio and Canada as described here, and truck traffic is using this designated route. Some photos of the work performed this week are included at the end of this post.

We will continue keeping the community informed through regular updates on this blog, www.WeAreWolverine.com, and through information posted at kiosks and in other locations accessible to the public.  As always, residents with questions are encouraged to contact Wolverine directly at HouseStreet@wwwinc.com or (616) 866-5627.

Update on Cleanup Work – Excavation Continues at Former Tannery

Wolverine is currently conducting cleanup work at the site of its former tannery in Rockford. Earlier this month we cleared vegetation, constructed temporary access roads, and staged equipment and supplies. We then installed silt curtains and cofferdams in the Rogue River, and began dewatering excavation areas. This work is described in more detail in blog posts here and here.

Last week, we began excavating, and this work is expected to include the removal of soil, sediment, leather scraps, and/or hides in the areas shown on this map and described below:

  • Excavation of sediments from two areas along the Rogue River, south of Rum Creek
  • Excavation of soils from four locations south of Rum Creek
  • Excavation of soils, leather scraps, and hides from two areas north of Rum Creek
  • Backfilling excavation areas

So far, we have completed excavating and backfilling one of the two areas of sediments south of Rum Creek. We have also completed excavating two of the four areas of soils south of Rum Creek, and started excavating a third area. Removed material is being taken to licensed landfills in Ohio and Canada as described here, and truck traffic is using this designated route.

Photos of the silt curtains, cofferdams, and excavation areas are included at the end of this post.

Update on Cleanup Work at Former Tannery – Excavation Starting Today

Wolverine is currently conducting cleanup work at the site of its former tannery, as further described here and here. Over the past two weeks our contractor completed preliminary work that includes clearing vegetation, constructing temporary access roads, and staging supplies and equipment. We spent the past two days installing turbidity curtains and cofferdams in the Rogue River and starting to dewater the dammed areas, as described here and shown in the photos at the end of this post.

Today, we will complete dewatering the dammed areas and begin excavating. This process will start with areas of soil and sediment being removed along the Rogue River, south of Rum Creek, as shown on this map. This material will be placed into lined containment cells located on the site, where any water in the soil and sediment will be allowed to drain into that lined cell.

This drained water will be taken to a facility in eastern Michigan for treatment and disposal. After reviewing several disposal options for the soil and sediment, we proposed taking this material to licensed landfills in Ohio and Canada, and the EPA has approved using these locations. We expect truck traffic to increase starting on Monday, October 21, and we have established this dedicated route to minimize the impact on neighboring residents, surrounding businesses, and the broader community.

Update on Cleanup Work at Former Tannery – Excavation Expected to Begin This Week

Wolverine is currently conducting cleanup work at the site of its former tannery, as further outlined here and here. Over the past two weeks our contractor has completed the following tasks, and photos of the work conducted to-date are included at the end of this post:

  • Brought trailers, construction equipment, and supplies to the site;
  • Fully fenced the work areas;
  • Conducted air quality monitoring;
  • Constructed temporary access roads;
  • Installed erosion and sediment controls
  • Temporarily re-routed the White Pine Trail as shown on this map; and
  • Cleared vegetation along the Rogue River

With these preliminary tasks either complete or nearing completion, we expect to commence excavation activities as early as Friday, October 17. This next phase of the work will start with the areas of sediment and soil being removed along the Rogue River, south of Rum Creek, as shown on this map. The process for this work will include:

  • Installing Turbidity Curtains in the Rogue River – turbidity curtains, also known as silt curtains, are designed to prevent the migration of sediment or other material from the site into the river, and they will remain in place during all riverbank construction and excavation work

 

  • Installing Water-Filled Cofferdams in the Rogue River – cofferdams are temporary, water-filled enclosures designed to help create a dry environment along the riverbank in which to conduct excavation activities. Examples of the dams we will be using can be seen at damitdams.com.

 

  • Dewatering Excavation Areas – once the cofferdams are in place, water within the dammed areas will be pumped out to create a dry work-space for the excavation. This water will pass through silt bags to prevent sediments from migrating into the river.

 

The EPA has approved this upcoming phase of the work, and will be on-site alongside Wolverine’s contractors. Any hazardous waste from these excavation activities will be sent to a landfill licensed to accept those wastes. All other material will also be transported offsite in accordance with applicable laws and regulations, and we are working to finalize specific locations.

As excavation begins, truck traffic to and from the site will increase. To limit the impact of this work on neighboring residents, surrounding businesses, and the broader community, we have established a designated truck route as shown on this map.

We will continue keeping the community informed through regular updates on this blog, www.WeAreWolverine.com, and through information posted at kiosks and in other locations accessible to the public.  As always, residents with questions are encouraged to contact Wolverine directly at HouseStreet@wwwinc.com or (616) 866-5627.
