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.

PLEASE TAKE NOTE:  

Hyatt Line Gas Main:  Work to install the new Hyatt Line Gas Main, which is not related to the MGP remediation, continues at the PSE&G Harrison Site. 

  • Work is expected to take place on Saturday, September 26th.
  • 10 hour days, 6 days per week are anticipated during the maximum 14-day-long gas outage, which is ongoing  through October 3rd.  All monitoring and mitigation measures will be maintained, including dust and odor controls. 

Anticipated Work for the Week of September 28 – October 2

Remediation Activities – (See Figure 1 below and on the website)

  • Continue pre-excavation and clearing of subsurface obstructions and debris within ISS areas. 
  • Continue ISS pilot in northwestern area of the work site.  
  • Initiate ISS pilot in eastern portion of the site.  
  • Transport excavated soil from the site by trucks for disposal or reuse at a New Jersey licensed facility.
  • Operate temporary wastewater treatment facility to control groundwater and surface water accumulations during work activities. Treated water will be discharged in accordance with a permit issued by the Passaic Valley Sewerage Commission. 
  • Continue pre-trenching and subsurface demolition to cut and cap underground utilities and remove old infrastructure.  This work will generate sounds from breaking of concrete and removal of metal piping and other materials. 

Continue Monitoring & Mitigation Measures

  • Apply dust suppression and odor controls, as needed, during remediation activities. 
  • Continue vibration monitoring between remedial work and the nearest onsite buildings.
  • Continue to perform perimeter air monitoring when soil disturbance work is in progress. The majority of air monitors are located each day based on location(s) or work being performed. There are two stationary air monitors – one by the Laboratory Air Intake and the other by the garage. 
  • 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.

Special Update September 2, 2020

All, 

Starting tomorrow, September 3, 2020, the Harrison manufactured gas plant (MGP) remediation contractor will begin soil removal activities within the area marked “Pilot Study Area” in the figure below. Excavation of a second area in the northeast section of the remediation project, also marked, is expected to begin on or about Tuesday, September 8, 2020.

In both areas, the work will seek to remove approximately the top 7 feet of soil below ground surface in preparation for In Situ Solidification and Stabilization (ISS) treatment of deeper impacted soils. ISS involves mixing impacted soils in place, below ground, with stabilizing agents such as Portland cement and blast furnace slag.  This work within the Pilot Study Area is anticipated to begin September 9, 2020.

Excavated soil will be removed from the site by trucks for disposal or reuse at a New Jersey licensed facility.

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. While the project team is committed to minimizing them, odors similar to fresh asphalt will at times persist. Control measures (such as water mist, foams and vapor suppressants, plastic sheeting and sand cover) will be used as needed to control potential dust and odors during excavation and non-work periods, including evenings and weekends. 

The Perimeter Air Monitoring Plan designed specifically for this site’s conditions is being implemented. For more information, you can visit the project website: www.HarrisonMGP.com.

Please feel free to share this information with others and let me know if you have any questions or concerns. The regular Weekly Update will be issued this week on Friday, ahead of the Labor Day holiday. In observance of the holiday, no work will be performed on Monday, September 7, 2020.
