Environmental Restoration

The Environmental Restoration Program (ERP) manages the environmental cleanup of all Air Force bases. Past industrial activities have resulted in contamination of the soil and water at Travis AFB.  The ERP is committed to restoring the soil and water to a condition that is protective of human health and the environment as quickly as possible.  The links located in the sidebar to the right provide access to information on our progress as well as connections to the primary environmental regulatory agencies that provide oversight of the Travis AFB ERP.

The Travis ERP staff, with input from three federal and state of California regulatory agencies and the local community, manages the cleanup effort.  Prior to 2013, the ERP staff was attached to Travis AFB and was assigned to the 60th Civil Engineer Squadron.  As part of the Air Force transformation, the restoration efforts at all Air Force installations were centralized, and the Travis ERP staff is now a part of the Travis Installation Support Section (ISS) and attached to the Air Force Civil Engineer Center (AFCEC) in San Antonio, Texas.  Even though the Travis ISS is a tenant organization on Travis AFB, it coordinates all restoration activities with base leadership and various offices to promote soil and groundwater cleanup and support the base mission.

Public Participation

The public is encouraged to participate in the Travis AFB Environmental Restoration Program (ERP); this display of the steps of the Superfund cleanup process shows the opportunities to review restoration documents and provide comments to Air Force officials.  Current information on the program can be found by navigating throughout this website. You can learn more about public participation in the Travis ERP via the Travis AFB Community Relations Program Update, which explains how interested community members can access information about environmental cleanup activities at Travis AFB, can express community concerns to base representatives, and can get involved in the decision-making process.

To receive up-to-date information on progress of the ERP, you can get on our mailing list for The Guardian; the Travis AFB Environmental Restoration newsletter that is mailed each quarter to interested community members.  We also send out an electronic version of the newsletter (the E-Guardian) for those with Internet access who want to save paper and get the newsletter sooner. Tell us you want to be added to the mailing list of either the paper or electronic version by emailing us

One of the best ways to participate is to attend the April Restoration Advisory Board (RAB) meetings and make your opinions known. Below are several important links which will give you more information on the RAB and how to contact the RAB members, as well as a calendar of when public meetings are held.

Your participation in the Travis AFB environmental cleanup program is welcomed!  The following links provide additional information to assist interested community members in understanding how they can participate in the Travis AFB ERP.

Fuel Leak Investigation

In February 2009, a petroleum leak was discovered along a pipeline that provides jet fuel to Travis AFB. Officials identified the source of the leak, shut down the pipeline temporarily, and began fuel recovery operations. The first fact sheet describes the initial response in more detail.

In March 2010, Travis AFB began collecting and analyzing soil and groundwater samples to determine the nature and extent of the petroleum contamination.  This site investigation showed more data is needed to identify the most appropriate cleanup technologies. The second fact sheet describes the site investigation in more detail, and the third fact sheet discusses the remedy selection process.

In October 2010, Travis AFB conducted an excavation of the fuel-contaminated soil along the pipeline.  Once complete, the excavation void was10 feet wide by 60 feet long by 12 feet deep.  All contaminated soil was transported by truck to an appropriate landfill, and the void was backfilled with clean soil.  The objective of this excavation project was to remove as much of the petroleum contamination as possible.

In 2013, a Dual-Phase Extraction (DPE) system was installed to extract as much fuel from the subsurface as possible.  After a few months, it had removed over 3500 pounds of petroleum in the form of vapors and 350 pounds of petroleum liquid.  The DPE system was shut down to verify that most of the liquid had been removed.  In 2014, the DPE system was run one last time to extract any residual liquid, followed by the introduction of a chemical oxidant.  The oxidant stimulates the growth of naturally-occurring microbes that break down the remaining fuel into harmless compounds.  The fourth fact sheet describes these technologies in more detail.

By January 2016, it appeared that the oxidant had broken down the residual fuel.  However, the Solano County Department of Resource Management, which oversees this cleanup project, requested additional data to verify that the cleanup is complete.  The Air Force agreed to install two additional monitoring wells and analyze water samples from each well for four quarters (a total of one year). 

In addition, multiple soil samples from different depths will be collected and analyzed for fuel constituents.  After this data is collected and Solano County is satisfied with the results, the Air Force plans to remove all wells and return all impacted property to its original condition by the middle of 2017.  The fifth fact sheet describes the final cleanup efforts in more detail, and the sixth fact sheet describes the closure of this site.

For more information, please contact Ms. Merrie Schilter-Lowe., 60th Air Mobility Wing Public Affairs Office at (707) 424-0135; or Ms. Courtney White, Solano County Department of Resource Management at (707) 784-6765.


Travis Air Force Base hosts a rich eco-system within Solano County. There is an ongoing environmental cleanup program here to reduce the risk of chemical exposure, and protect human health and the environment. This program is called the Environmental Restoration Program (ERP).

Restoration Schedule

Next Restoration Advisory Board Meeting: The next meeting is scheduled for April 19, 2018 at 7 o'clock PM at the Office of the Northern Solano County Association of Realtors at 3690 Hilborn Road, Fairfield CA.   If you would like more information or need special accommodations for the RAB meeting, please contact Mr. Lonnie Duke at (707) 424-7520.
