PSE&G Former Harrison MGP Site: Weekly Project Update – Week of 11/9/20

The PSE&G site remediation group and its environmental contractor, Sevenson Environmental Services, Inc., are conducting activities to remediate soils at the Harrison former MGP site. Work began in July 2020 and is expected to end by December 2022. Work is being performed in two phases.

The sitewide remediation project includes removing approximately the top 7 feet of soil below ground surface in preparation for treatment of deeper impacted soils through In Situ Solidification and Stabilization (ISS). ISS involves mixing impacted soils in place, below ground, with stabilizing agents such as Portland cement and blast furnace slag. Impacted soils in the vicinity of the active Meter and Regulating (M&R) Station and its infrastructure will remain in place but contained through installation of below ground slurry walls. 

These updates are being issued weekly throughout the duration of the project to provide a review of key activities performed at the site over the past week as well as a look ahead to the next week’s anticipated activities. They are also posted to the project website: www.HarrisonMGP.com.  If you have any questions or concerns about the project, please: visit our website at www.harrisonmgp.com; call the PSE&G Harrison Project Information Line at (855) 356-2383; or email us at comments@harrisonMGP.com.

  • Maintain site security 24 hours a day, 7 days a week.

NOTE:  Odors associated with some constituents can often be detected at levels that are well below what would be considered a health concern and often below what can be detected by an air monitoring instrument. The MGP project continues to:

  • Apply vapor mitigation sprays in the excavation area.
  • Apply odor suppressing foams in the excavation area and in the trucks while being loaded.
  • Use odor suppressing foams more frequently and in greater amounts.
  • Cover project soil piles with plastic when work is completed.
  • Perform daily odor assessment walks around the MGP remediation work areas to determine if and at what levels odors may be detected beyond the work area fenceline. 

Other control measures, including water mist and sand, will be used as needed to control potential dust and odors during excavation and non-work periods, including evenings and weekends. The MGP project performs continuous air monitoring during working hours around the site, including monitoring stations by the welding shop, laboratory, and gym buildings. Confirmatory air samples are taken weekly and all results have been below our action levels. 

Work Completed November 2 – November 6

Remediation Activities

  • Excavated soil to remove approximately the top 7 feet of soil below ground surface in preparation for ISS.
  • Performed ISS in area 1A.
  • Continued pre-trenching and subsurface demolition to cut and cap underground utilities and remove old infrastructure.

PSE&G Former Harrison MGP Site: Weekly Project Update – Week of 9/28/20

The PSE&G site remediation group and its environmental contractor, Sevenson Environmental Services, Inc., are conducting activities to remediate soils at the Harrison former MGP site. Work began in July 2020 and is expected to end by December 2022. Work is being performed in two phases.

The sitewide remediation project includes removing approximately the top 7 feet of soil below ground surface in preparation for treatment of deeper impacted soils through In Situ Solidification and Stabilization (ISS). ISS involves mixing impacted soils in place, below ground, with stabilizing agents such as Portland cement and blast furnace slag. Impacted soils in the vicinity of the active Meter and Regulating (M&R) Station and its infrastructure will remain in place but contained through installation of below ground slurry walls. 

These updates are being issued weekly throughout the duration of the project to provide a review of key activities performed at the site over the past week as well as a look ahead to the next week’s anticipated activities. They are also posted to the project website: www.HarrisonMGP.com.  If you have any questions or concerns about the project, please: visit our website at www.harrisonmgp.com; call the PSE&G Harrison Project Information Line at (855) 356-2383; or email us at comments@harrisonMGP.com.
