Recovery Wells on Glenwood Drive
Work at the three newly installed recovery wells on Glenwood Drive is actively underway and is anticipated to continue over the next few weeks. Development of each recovery well, which was a one-time activity, was completed on June 4-5. Over the next several weeks, the primary activity at each of these recovery wells will be daily gauging for presence of jet fuel. This work will involve a two-person crew with a pickup truck and related traffic control (i.e., cones and flags) in the roadway.
Last week, Energy Transfer/SPLP also began active product recovery, which will continue on an as-needed basis based on the observed presence of product in the recovery wells. When active product recovery occurs, half of the roadway on Glenwood Drive will be temporarily closed, with traffic controls in place. SPLP is also implementing passive recovery of jet fuel, utilizing absorbent socks that are placed in the recovery wells when active recovery is not underway. All recovered jet fuel product and any other waste materials will be safely removed for offsite disposal.
Additional Upcoming Site Activities
Week of June 9
During the week of June 9, SPLP’s contractors have performed borehole geophysical logging and imaging of each of the three recovery wells on Glenwood Drive. This work involves using a wireline winch mounted in a standard pickup truck with a cap. The wireline runs about 20 feet from the back of the truck to a pulley on a tripod over the well. Various cylindrical tools and sensors are sequentially attached to the wireline and lowered into the borehole. The tools are staged on a set of sawhorses next to the truck. The winch is powered by a standard (camping-sized) generator; this is the only noise associated with this work, and the pickup truck will be turned off and not idling. The truck, sawhorses and pulley tripod will be situated on the public roadway (Glenwood Drive) and will only block one lane of traffic. Traffic control will be provided to ensure safe passage of vehicles travelling the street.
SPLP’s contractors are also beginning to perform seismic refraction surveys in the Mt. Eyre neighborhood. Seismic refraction surveys will be used to further refine geological considerations for site investigation and remediation efforts, including determining the depth to, and nature of, the soil-to-bedrock interface within the neighborhood. The first seismic refraction survey will be performed on June 12 in the township’s open space area located at the western edge of the Mt. Eyre neighborhood. SPLP is also in the process of obtaining permission from landowners to perform seismic refraction surveys in locations throughout the Mt. Eyre neighborhood.
Week of June 23
SPLP’s contractors are also planning to perform packer testing of the three recovery wells on Glenwood Drive during the week of June 23. The packer testing will assist to provide further details on site geological considerations, fracture zones, and groundwater flow direction. The packer testing will require temporary daytime closure of Glenwood Drive in the area of the recovery wells, i.e., between Walker Road and Spencer Road. Road signage and traffic control (i.e., flaggers) will be deployed in a similar manner to the traffic control that occurred during the installation/drilling of the recovery wells a few weeks ago.
Inline Inspection Tool Runs
Over the past several months, SPLP has employed vendors to perform a number of inline inspection runs along the entire pipeline. All of these runs have been successfully completed and the vendors have confirmed successful data capture. The vendors are now reviewing the data to generate reports, which will take months to complete. The completed analysis will be provided to SPLP.
