NE Park Update: Parcel D TPH Cleanup is Complete

30 Jun

During May-June 2014, a remediation crew from V3 Companies performed dig/haul of petroleum-impacted soil on Parcel D within the NE Park site .  The objective of the work was to remove soil impacted with levels of total petroleum hydrocarbons (TPH) that exceed site-specific Illinois EPA cleanup standards. Summary of findings of fieldwork below and can also be accessed online.

Excavation in Action!

Soil Remediation Activities

The cleanup work was performed in accordance with the IEPA-approved Remedial Action Plan (RAP) consisted of the excavation and haul-off of approximately 300 tons of TPH-impacted soils, and landfill disposal of these soils as a non-hazardous certified special waste.

After the impacted soils were removed, V3 collected soil verification samples from the excavation sidewalls and bottom. Soil analytical results for the verification samples were well below the site-specific soil TPH cleanup objective. No further soil remediation is required to address the issue.

Exploration for the Suspected Storm Sewer

While the cleanup excavation was open, V3 also explored the area where an suspected concrete storm sewer was previously observed in a soil boring. The excavator encountered concrete debris and a concrete floor slab at a depth of approximately 10 feet below grade, where water was observed flowing from beneath the slab. Remnants of the original soil boring were also encountered in this area. After further digging, no actual storm drain or sewer was found. It is evident that the concrete slab and groundwater found in the excavation were the features observed in the previous soil boring.  Thus, there is no evidence of a storm sewer in this area. The materials were actually a piece of the former building foundation from when the site was a brickyard long ago. No further work is required to address this matter.

Excavation Backfill

The remediation excavation was subsequently backfilled with the stockpiled overburden soils and clean soil that was imported to the site.  The area was rough-graded smooth to match the surrounding ground surface.

GW Monitoring Well Installation

One permanent groundwater monitoring well was installed down-gradient from the TPH cleanup area.  No obvious evidence of TPH impacts was observed in the well boring soil samples, and no visual evidence of petroleum product or impacts was observed in the groundwater samples.   Soil samples were collected for laboratory analysis of BTEX, PAHs and TPH.  Groundwater samples were analyzed for BTEX and PAHs.Post Remediation Activities

Soil analytical results were reported to be non-detect for BTEX and well below the site-specific TPH soil cleanup objective.  Groundwater analytical results were reported to be non-detect for BTEX and PAHs. No further action is required with respect to groundwater down-gradient from the cleanup area.

The cleanup activities and results will be documented in the forthcoming Interim Remedial Action Completion Report (RACR), which will be submitted to the Illinois EPA Site Remediation Program for review in the 1st week of July.

Parcel D TPH Cleanup Schedule Update

10 Apr

The Blue Island Brownfields Initiative would like to announce that our website is now updated with the following information related to the Parcel D TPH Cleanup:

As of April 10, the following is a tentative schedule of field activities:

  • Week of April 7: V3’s crew will begin to mobilize and prepare site for excavation.
  • April 15: Waste characterization sample for lab analysis taken
  • Week of April 21: Remediation excavation work to begin, pending weather and ground conditions.
  • Week of April 21 – April 25: V3’s crew to perform video camera survey of sewer line; cap sewer line; install 1 groundwater monitoring well down-gradient from the cleanup area.

Please note that there is little to no Public Health Risk associated with this cleanup process. City’s environmental consultant, V3 Co. will follow proper cleanup procedures prescribed by the USEPA and as outlined in the Health & Safety Plan.

Thank you for your ongoing interest in this project. The Blue Island Brownfields Initiative will continue to keep you informed with updates as they occur.

NE Park Cleanup & Redevelopment: Feb 2014 Updates

3 Mar

February was another busy month for the NE Park project team planning for the cleanup and redevelopment of the former landfill property on 119th & Vincennes. Check out of a few of the activities below and feel free to contact us at brownfields@cityofblueisland.org if you have any questions or would like additional information.

Parcel D TPH-Cleanupbibi_Feb5thCleanupMeeting_V3(2)
  • 02/05/2014, public meeting for comment on draft ABCA was held at Blue Island Public Library. The meeting was well attended. The community asked lots of questions related to the cleanup and overall site redevelopment. It was really nice to see increased community interest in the project and its impact. A Public Meeting Summary is available online.
  • 30-Day Public Comment Period ended on 02/28/2014. All officially submitted public comments will be forwarded to the City’s environmental consultant for response and inclusion in the Decision Document & Response to Public Comment. Additionally, the draft ABCA will be updated, where appropriate, based on submitted comments.
  • The Decision Document & Response to Public Comment to be completed in March 2014. The Decision Document & Response to Public Comment will document the alternative selected for site remediation and summarize public comment and response to public comment.
  • Review the Upcoming Activities & Schedule to know what is next on Parcel D TPH Cleanup.
Sitewide Cleanup Planning
  • Our environmental consultants at Weaver Boos are putting together a work plan for another round of Supplemental Investigations to address any/all data gaps identified by IEPA during their review of ROR/RAP and in response to IEPA comment letter received on 11/18/13. This site-wide workplan will include cleanup plans for both the East and West Parcels. We anticipate that the document will be submitted to IEPA before the end of March.
Master Infrastructure Planning
  • Project team completed conceptual development plan to include green stormwater management system for the entire NE Park site.
  • Redevelopment plans include a retail development on the north portion of the site, community green space towards the center and light industry to the south. The green space will serve as neighborhood recreational space and also the master stormwater management system for the district. The site plan also includes a wetland restoration.
  • Model traffic data necessary to justify any changes, if needed, to adjacent IDOT roadways will likely be completed before end-March 2014.
