Update #30: Colonial Pipeline – SR2448 Response, September 03, 2021 – 3:30 PM EST

Colonial Pipeline Update

As Colonial Pipeline Company continues our remediation and recovery efforts at the site of an August 2020 release near Huntersville, North Carolina, safety remains a central focus and is embedded in every aspect of our response.  We continue to work closely with local, state and federal regulators and communicate with key stakeholders to keep them informed of our activities and update them on our progress.

Recovery Efforts

Our extensive network of monitoring and recovery wells continues to inform our ongoing recovery and remediation efforts.  As of August 23, 2021, we have installed 284 wells to support environmental remediation, including 109 monitoring and 79 recovery wells.  Data from these wells continues to show that product remains contained in the general vicinity of the release location.

As Colonial reported earlier this week to the North Carolina Department of Environmental Quality (NCDEQ) as of August 23, 2021, Colonial had recovered approximately 29,833 barrels of product.

Our priorities remain safely recovering product and restoring the area and surrounding environment.

Environmental Update

Earlier this year, Colonial worked with NCDEQ’s Department of Air Quality and Mecklenburg County Air Quality to install an ambient air sampler at the site.  Any compound concentrations contained in samples collected between April 4 and July 27, 2021 were below the CDC’s Agency for Toxic Substances and Disease Registry (ATDSR) and National Institute of Occupational Safety and Health (NIOSH) guidelines. The information on Air Quality Monitoring is available on the NCDEQ website.  Colonial was also honored to receive a Mecklenburg County ACE Award for ongoing Air Compliance Excellence at our Charlotte Delivery Facility.  This marks the eighth year in a row that Colonial has received this award.

We remain diligent in our water monitoring efforts and continue to conduct weekly tests of water supply wells of homes within the 1,500-foot monitoring radius established by NCDEQ and biannual testing of water supply wells located between 1,500 and 2,000 feet from the release point. No petroleum constituents have been detected in any of the water supply well samples that have been analyzed since the release occurred.

We remain steadfast in our commitment to human and environmental health and safety. These priorities continue to guide our day-to-day operations as a company and our response in Huntersville and Mecklenburg County.
