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 where more information about the project scope and history can be found. If you have any questions or concerns about the project, please call the PSE&G Harrison Project Information Line at (855) 356-2383 or email us at comments@harrisonMGP.com.

NOTES:

  • Demolition of Garage – Demolition of the garage is expected to begin next week, pending Town Permit Approval.

  • A new onsite traffic pattern is in effect. – See Figure 2 below.

Anticipated Work for the Week of May 17 – May 21

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

  • Continue installation of a hydraulic barrier wall around the existing Metering & Regulating (M&R) Station and associated infrastructure. The One-Pass Trencher equipment mixes bentonite into the soil, similar to ISS, to install the barrier into an existing clay layer to depths of between 60-100 feet. 
  • Continue to pre-clear Phase 2 areas for In Situ Stabilization (ISS) work. This work will generate sounds from breaking of concrete and removal of metal piping and other materials.   
  • Continue to backfill and compact clean fill in completed areas with intermittent use of vibratory rollers.
  • Perform soft dig to locate underground utilities and cut and cap unused utilities.
  • Transport excavated soil and concrete from by trucks for disposal or recycling at a licensed facility.
  • Operate temporary wastewater treatment facility to control groundwater and surface water accumulations during work activities. Treated water is discharged in accordance with a permit issued by the Passaic Valley Sewerage Commission. 
  • Maintain soil and sediment erosion controls. 
  • Maintain temporary fencing around active work areas.

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. 
  • 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 fence line. 

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 weld and tool shop, laboratory, and gym buildings. Confirmatory air samples are taken weekly and all results have been below our action levels. 

Demolition

  • Begin abatement of the garage located in Phase 2 area 2B.

Work Completed May 10 – May 14
