The California State Lands Commission (the Commission) administers leases related to oil and gas operations located in and adjacent to the state’s waterways, beaches, and coastline. When four oil and gas platforms (“4H Platforms”) were decommissioned and removed from the Santa Barbara Channel in the mid-1990s, each left behind a mound of byproducts from drilling operations which over time became covered with sediment and shells. The Commission is in the process of determining whether Chevron, the lease holder, has met the lease obligations, which include a proposal to keep the 4H shell mounds in place in their current configuration, unless otherwise specified. To inform its decision, the Commission has produced a report summarizing impacts to public trust resources that could occur if the mounds are left in place. The Commission is partnering with Ocean Science Trust to lead a peer review process assessing the scientific merits of the report with the goal of ensuring that the decision is guided by sound science.
We are conducting a peer review process to ensure that seafloor mounds generated from now-decommissioned oil and gas platforms are managed responsibly.

Leading a Rigorous Scientific Review Process
To meet the Commission’s needs, we are implementing a scientific review process that promotes objectivity, transparency, candor, efficiency and scientific rigor. A multidisciplinary four-member review committee has been assembled that represents diverse expertise in oceanography, marine toxicology, ecology and seismic activity. Reviewers will remain anonymous until completion of the review to encourage candid feedback.
The final summary report will be delivered to the Commission in early 2023 and will be publicly available on this webpage shortly after.
