NBPL Miramar Fuel Pipeline and Relocation Project

U.S. Navy Preparing

Environmental Assessment for Encroachments 

Along Miramar Pipeline (Clairemont Mesa Area)

The U.S. Navy is proposing to relocate two segments of the Navy’s Miramar fuel pipeline from the current alignment in Clairemont Mesa to an adjacent City of San Diego right-of-way. The purpose of the proposed action is to maintain the pipeline between Naval Base Point Loma and Marine Corps Air Station Miramar in safe operational condition. The proposed action is needed to provide unencumbered access to the pipeline for regular inspection, routine maintenance, and emergency response. Non-Navy development has encroached upon the Navy easement. These encroachments diminish the Navy's ability to access the pipeline for maintenance and meet operational and mission requirements. In accordance with the National Environmental Policy Act (NEPA), the Navy is preparing an Environmental Assessment (EA) to evaluate the potential environmental impacts of the proposed action and is encouraging public participation in the environmental review process.

For more detailed project information, please see the Encroachments EA Fact Sheet prepared for the public scoping period.


Environmental Review Process

From March 1, 2019, through April 1, 2019, the Navy held a public scoping period to receive public input that would help the Navy identify environmental issues and potential alignment alternatives for analysis in the Draft EA. During the public scoping period, the Navy received comments on the proposed alternatives, as well as suggestions for other alternatives to consider. The Navy has been reviewing the alternatives suggested by the public to determine whether they are viable alternatives to be studied in the EA.

The Navy had expected the Draft EA to be available for public review and comment in summer 2019, but more time is needed to allow for thorough consideration of the alternatives suggested by the public during the scoping period.


Public Commenting Opportunity

The next public comment period will be when the Draft EA is available, which is expected in summer 2021.



The Miramar Pipeline is a Navy-owned and operated fuel pipeline extending approximately 17 miles between Naval Base Point Loma and Marine Corps Air Station Miramar. The pipeline was built in 1954 and provides fuel for ships and aircraft. The Miramar Pipeline is critical for supporting the Navy’s and Marine Corps’ fueling needs and operational mission.




The Navy is studying a range of reasonable alternatives for accomplishing the proposed action, as well as a “no action alternative.” The alternative pipeline routes  for the encroachments at High Tech High Mesa and Cannington Drive that were identified prior to the public scoping period are shown below. The Navy has been reviewing alternatives suggested by the public during the scoping period to determine whether they are viable alternatives to be studied in the EA.
