For Immediate Release:
State Regulators Reject Mendocino Railway's Mill Site Cleanup Proposal as Written
DTSC demands data and engineering support for the remaining Mill Site cleanup alternatives, along with effective fencing at Pond 8. Many of its concerns echo the Noyo Headlands Working Group's comments
FORT BRAGG, Calif. — The California Department of Toxic Substances Control (DTSC) has rejected, as written, Mendocino Railway's draft Feasibility Study Addendum for the contaminated ponds on the former Georgia-Pacific mill site, issuing fifty comments and requiring a revised document and a written response to every comment within 90 days of receipt of its letter.
In an August 19, 2026 letter to the railroad's consultant, DTSC found that the railroad's proposal for the contaminated sediments in the Operable Unit E ponds, Pond 6, Pond 7, Pond 8 and the North Pond, rests on unsupported assumptions and on risk figures more than a decade old.
For the North Pond and Pond 6, the railroad assumed how deep the contamination goes; DTSC said those depths must be supported by sampling data from the ponds themselves. DTSC also directed the railroad to evaluate, in the Addendum itself and not in a later design phase, how well each cleanup alternative would hold up against sea level rise and climate change over the long term.
Citing photographs provided by members of the public, the agency directed the railroad to withdraw its description of Pond 8 as effectively fenced off until the fence is replaced.
Many of the problems DTSC identified were also raised in a ten-page comment letter, with supporting appendices, that the GrassRoots Institute's Noyo Headlands Working Group submitted to the agency in October 2025.
The Working Group applauds DTSC for doing exactly what a regulator is supposed to do: reading the document closely, asking for evidence, and requiring the railroad to support its conclusions. The letter calls for site data, a demonstration that the recommended remedies protect human health, engineering analysis, and a cleanup that takes the community's vision for the site seriously. That is what the Working Group asked for, and it is what Fort Bragg deserves.
