The Port of Long Beach released a draft study Friday examining a proposal by Tesoro Refining and Marketing Co. LLC to demolish the Tesoro Calciner facility located at 2450 Pier B St., Long Beach, 90813.

There is currently no new proposed development, no new proposed operations or proposed new land uses for the site following the proposed demolition of the facility.

The study being released by the Port is called an Initial Study (IS), which concluded that there would be less than significant impacts to the environment with the incorporation of mitigation measures; therefore, a Mitigated Negative Declaration (MND) has been prepared. The public can comment on the draft IS/MND through 4 p.m. Monday, July 8. It is available at

The Calciner facility was originally constructed in 1982 by Martin-Marietta Corp. as a joint venture with Champlin Petroleum Co. Tesoro began operating the Calciner facility in 2013 and ceased operations in June 2022. Prior to termination of their lease with the Port, Tesoro is required to remove from the premises all improvements and property belonging to it and restore the site to a condition equivalent to or superior to its condition prior to the commencement of the lease.
