Special Update August 28, 2020

The Harrison MGP Remediation contractor Sevenson is today constructing a truck scale near the utility air bridge. The resulting traffic pattern is shown below. Sevenson has established stop signs (one in each direction), traffic cones and cone bars to clearly indicate the traffic pattern and high visibility traffic cones and high visibility cone bars to indicate the DGA roadway. 

This will be in place for approximately one year, through July 2021.  Please share this information with others on your team, and let me know if you have any questions or concerns.

Later this week or early next week, the remediation contractor Sevenson will install an air bridge over the gas lines to enable safe access to the western portion of the site by equipment needed for site remediation. This section will be reinforced with approved DGA, graded & compacted to expand the area necessary for vehicles to safely make turns in both directions. As a result of this work, there will be an adjusted traffic pattern in that area (Please see the figure below). The air bridge and adjusted traffic pattern will be in place for approximately one year.

  • Traffic control measures will include stop signs in each direction, as well as traffic cones and cone bars to clearly indicate the traffic pattern.
  • The green line on the figure below indicates a gate constructed with temporary fence panels to allow only trucks supporting the project to use the ramp.

On or about Monday, July 13th, a contractor working for the Harrison remediation group will be conducting soil sampling through installation of soil borings at 6-7 locations between the materials storage building and the trailers that sit immediately adjacent to it, to the north. 

The work is expected to take up to three days and is weather dependent. Work hours will be 7 a.m. – 2:30 p.m. Air monitoring will be conducted during all soil disturbance activity.  

In preparation for the work, on Friday, July 10th, a crew marked underground utilities in the work area through the use of ground penetrating radar equipment. A utilities one-call mark out was already performed. 

We thank you for your cooperation.

Jul 06

Update July 6, 2020 – Revised

Due to unforeseen logistics, representatives from the environmental consultant PS&S will be onsite to begin baseline air monitoring Wednesday, July 8, 2020. The air monitoring will be completed by Tuesday, July 14, 2020 to allow for five full days of air monitoring and sampling. The baseline air monitoring was originally supposed to begin today, Monday, July 6, 2020. The purpose is to document existing background air quality conditions. The project perimeter air monitoring will not begin until remedial soil disturbance activities commence.

Jun 26

Update June 26, 2020

  1. In preparation for the start of the next phase of the Harrison Manufactured Gas Plant (MGP) Remediation, currently anticipated to begin later this summer, representatives from the environmental consultant PS&S will be on site from Wednesday, July 1 through Friday, July 3 to receive and set up air monitoring equipment at the locations generally identified as green circles (not to scale) on the map below. Following the July 4th holiday,  air monitoring will be performed, starting Monday, July 6 and continuing through Friday, July 10.  The purpose is to document existing background air quality conditions.  The project perimeter air monitoring itself will not begin until remedial soil disturbance activities commence.
  1. Unrelated to the Harrison Manufactured Gas Plant (MGP) Remediation, the remediation group also soon will be establishing a temporary area for staging approximately 20-26 drums on site, while the soils within are being characterized and waiting for disposal. An earthen berm will be built around the area approximately 12 ft x12 ft in size identified in blue (not to scale) on the map below, as a second containment system. Once all drums are disposed, the berms and staging area will be dismantled and the area restored to its previous condition.
