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.

Colonial Pipeline Update

Over the past year, Colonial Pipeline Company has made considerable progress in recovering free product from the subsurface and remains accountable and committed to staying onsite for as long as it takes to safely remediate the area.  The safety of human health and the environment has been and will continue to be the foundation of our recovery and remediation efforts.

Recovery Efforts

As part of our product recovery and remediation process, Colonial has deployed a network of recovery and monitoring wells that aid in product recovery efforts and provide data guiding our operations. Our product recovery efforts are ongoing, and as of July 20, 2021, Colonial has installed 274 wells to support environmental remediation, including 69 recovery wells and 109 monitoring wells at and around the release location.

As of July 27, 2021, Colonial has recovered approximately 29,173 barrels of product and we continue to utilize a series of monitoring wells at different depths located around the perimeter of the site to assess groundwater quality.  Information collected from those wells indicates that product remaining is contained to the general vicinity of the release location, and there is no evidence of free product in the perimeter wells.

To supplement our recovery and remediation efforts, Colonial will be drilling additional monitoring wells into deep bedrock at the site this week.  This work, which is being performed by Colonial under the guidance of the North Carolina Department of Environmental Quality, will provide valuable additional information about the site, which will help further refine ongoing remediation plans. We anticipate that this work will take approximately three weeks to complete.

While this work is in progress, there may be additional workers and equipment at the site, as well as a difference in the type of sounds coming from the site. To minimize impacts on our neighbors, we will limit operational hours for these activities to between 8 a.m. and 5 p.m., Monday through Saturday.

Environmental Update

In addition to product recovery efforts, Colonial continues to sample water supply wells on a weekly basis within the 1,500-foot monitoring radius established by NCDEQ, along with biannual testing of wells located between 1,500 and 2,000 feet from the release point. These tests are performed by a third party, submitted under chain of custody to NCDEQ certified labs, and shared with the homeowner and state regulators.

No petroleum constituents have been detected in water supply well samples. Colonial has also conducted regular environmental monitoring, such as surface water sampling and noise monitoring, and will continue to do so as long as we are onsite.

Colonial is immensely grateful for the efforts of all our local, state, and federal regulators who have been involved in the response to-date. We continue to work closely with the appropriate regulators and always aim to communicate openly with key stakeholders to provide updates on progress as we continue the response effort.

Our Commitment

We understand and regret any inconvenience this event has caused, and we are committed to being here for as long as it takes to safely remediate the area and also remain committed to earning back the trust of the community that has been our neighbors for more than 50 years.

Colonial Pipeline Update

As Colonial Pipeline Company continues our remediation and recovery efforts at the site of a release event outside of 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

Data collection from a growing network of monitoring and recovery wells, and other measurements, continues to inform our ongoing recovery and remediation efforts. To date, Colonial has installed 177 wells to support environmental remediation, including 108 monitoring and 69 recovery wells at and around the release location.  The well network includes a series of wells at different depths located around the perimeter of the site. Information collected from those wells continues to indicate that product remains contained to the general vicinity of the release location, and there is no evidence of free product in the perimeter wells.

As shared in the June monthly report to the North Carolina Department of Environmental Quality (NCDEQ), as of June 16, 2021, Colonial has recovered approximately 28,078 barrels of product. We expect to have recovered more than our previous release estimate of 28,571 barrels within a week. We continue to evaluate alternative methods to estimate the total volume released.  Those methods are complex and require multiple data points and assumptions, and the calculations from those models must be validated and reviewed.

Completion of site models, assessments, remedial design or ongoing remediation efforts are not dependent on, nor affected by, an updated estimated release volume. Our priority remains continuing to safely recover product and to restoring the area and surrounding environment.

Environmental Update

We have continued to conduct weekly tests of water supply wells for homes within the 1,500-foot monitoring radius established by NCDEQ and we have committed to biannual testing of wells located between 1,500 and 2,000 feet from the release point. These tests are performed by third-party consultants and submitted under chain of custody to NCDEQ certified third-party labs. The results are also shared with the NCDEQ.

No petroleum constituents have been detected in water supply well samples. Environmental monitoring, including air quality and noise, continues.

Colonial remains committed to protecting human health and the environment and we will be here for as long as it takes to recover product and safely remediate this area.

Colonial Pipeline Update

Colonial Pipeline Company continues to make progress recovering product at the site of the August 2020 release, with data collection from a growing network of monitoring and recovery wells, and other measurements, informing our ongoing recovery and remediation efforts.

A network of 168 wells has been installed over the past nine months, which includes a series of wells at different depths located around the perimeter of the site. Information collected from those wells indicates that product remains contained to the general vicinity of the release location, and there is no evidence at this time of free product in the perimeter wells.

As previously noted, we have reported that additional data, including the results of a geological analysis completed last month, show there are areas where product is located deeper than originally modeled. We anticipate product can be recovered with the existing remediation technology utilized at the site, and we have made adjustments to our plan as needed.

The additional data also brings more clarity to where the product is located and therefore assists in safely recovering product and remediating the site, which remains our top priority. This data also shows our recovery plan is working as designed; however, it does not indicate the volume of product located deeper in the soil.

Previous environmental modeling estimated that a total of 28,571 barrels of product were released from the pipeline in August. As of May 25, 2021, we have collected 27,217 barrels.  Based on continued recovery rates, we have notified the North Carolina Department of Environmental Quality (NCDEQ) that the previous volume estimate will likely be exceeded.  Each volume estimate that Colonial has provided since discovering the release has been based on the best available data at that time, and we will continue to follow the science and communicate what we find with the public and our regulators.   We will also continue to provide NCDEQ updates of volume recovered on a regular basis.

Conducting an updated environmental assessment of the total volume released would require halting product recovery for a period of time, possibly several weeks.  We believe that doing so would not be in the best interest of protecting human health and the environment and would impair the goal of completing product recovery as quickly and safely as possible to minimize the risk of migration.

Colonial continues to evaluate alternative methods to estimate the total volume released.  Those methods are complex and require multiple data points and assumptions, and the calculations from those models must be validated and reviewed. Because of those complexities, and the potential adverse impact of halting recovery efforts, we have notified NCDEQ that we are unable to provide an updated volume estimate at this time as we continue to focus on safely recovering product.

An updated estimated release volume is not needed to complete the conceptual site model or the Comprehensive Site Assessment, and has no impact on remedial design and ongoing remediation efforts.  Colonial has collected more than 600 surface and water supply well samples since last August.  No petroleum constituents have been detected in those water supply well samples.  In addition, none of the surface water samples have exceeded applicable state standards.  Environmental monitoring, including air quality and noise, continues.

Colonial remains committed to protecting human health and the environment and is taking full accountability for remediation of this location.  We will be here for as long as it takes to safely remediate this area.

Colonial Pipeline Update

As part of our nation’s critical energy infrastructure, the 5,500-mile Colonial Pipeline system safely delivers more than 100 million gallons of refined petroleum products such as gasoline, diesel, jet fuel, home heating oil, and fuel for the U.S. military each day.

Through our Safety Management System (SMS), we have a systematic approach to safety that is integrated throughout the company.  This SMS framework drives continuous improvement and excellence, allowing us to learn from operational events such as the August 2020 release from our pipeline outside of Huntersville, North Carolina.

Regulatory Update

Colonial has received and is reviewing a notice issued in connection with this release by the U.S. Department of Transportation’s Pipeline & Hazardous Materials Safety Administration (PHMSA).  We will respond to the Notice of Proposed Safety Order (NOPSO) within 30 days as requested by the agency.

In accordance with our SMS practices, Colonial began seeking to implement learnings from the Huntersville incident almost immediately after it occurred.  This included identifying sections of pipe with potentially similar conditions and excavating, evaluating and in some cases enhancing those pipe segments.  Colonial also has leak detection systems in place on each of its pipelines that meet, and in some cases exceed, current regulatory requirements and continues to invest in improvements to leak detection technology.

Additionally, in November 2020, Colonial removed and replaced the impacted section of pipe from the release area to allow for additional analysis, even though this removal was not required.  Colonial sent the section to a third-party laboratory for metallurgical analysis to better understand what happened, and to apply findings to make improvements going forward. This analysis is complete and confirms the preliminary findings that a through-wall crack in the pipe wall was the source of this release.

We will continue to learn from this event and apply those lessons learned to our overall operations.

Environmental Update

From our initial response on Day One, Colonial continues environmental remediation and product recovery activities at the release site in close coordination with the North Carolina Department of Environmental Quality (NCDEQ) and Mecklenburg County.

To date, Colonial has installed 158 wells to support the environmental remediation, including 96 monitoring and 62 recovery wells.  Additionally, Colonial has collected approximately 600 samples from water supply wells and surface waters. Petroleum constituents have not been detected in any of these samples.

Colonial and NCDEQ have also collected samples to monitor for and ensure that per- and polyfluoroalkyl substances (PFAS), which can be found in a variety of substances including some fire-suppression agents, was not used at the location.

As previously stated, the response team at the Huntersville release site used a fire suppression product containing F-500 encapsulate agent, which, according to the manufacturer, does not contain PFAS. The Safety Data Sheet (SDS) for the F-500 encapsulate used onsite can be viewed here. We continue to collaborate with NCDEQ in ongoing reviews of data collected during environmental testing.

Colonial is committed to protecting public safety, restoring the natural environment, and meeting or exceeding all regulatory requirements. We also remain committed to regaining the trust of our neighbors who have been affected by this event.
