Indian Valley Wood Utilization Campus

Removal Action Workplan documents at the end of this page.


To further respond to declining forest health, high risk of catastrophic wildfire, and poor socioeconomic conditions in a community that has historically had a strong presence of the timber industry, the Sierra Institute is working to redevelop an old sawmill site to a wood products campus in Crescent Mills. This campus will consist of a variety of businesses that generate value-added products out of small-diameter trees and other woody biomass.

Potential businesses include a small-scale bioenergy facility, processed wood chips for use in biomass boilers, mass timber production, packaged and dried firewood, soil amendments, and more.

This campus will provide direct benefits to communities and forests of Plumas County as it will develop a market for small-diameter trees and forest restoration byproducts. Sufficient processing infrastructure and a strengthened market for forest biomass will allow for increased pace and scale of forest restoration activities in Plumas County and the Upper Feather River Watershed. At full build-out, this campus could generate between 15-30 industry jobs for local residents.

Following several years of negotiating planning and liability challenges, cleanup efforts are well underway at the Sierra Institute's Crescent Mills site. Over the past three years, Sierra Institute has made significant progress in cleaning up the historic lumber mill and has been advancing work necessary to redevelop this Brownfield site into a wood products campus. Remediated portions of the site are already being utilized to support businesses targeting biomass utilization and expedite Dixie Fire recovery efforts.
Sierra Institute is applying for an EPA Brownfield Cleanup Grant to fund additional cleanup and redevelopment work at the former Louisiana Pacific mill site in Crescent Mills, Ca. Prior to submitting the application, Sierra Institute is seeking public comment on the proposed action.
The following documents are available for review and comment either online:
or at the Sierra Institute’s office in Taylorsville, Ca at 4438 Main Street.
There will also be a public meeting held on Tuesday November 30th, 2021 from 5:00 pm - 6:00 pm at the Crescent Mills Fire Hall located at 36 Carter Street, Crescent Mills CA 95934 to discuss the cleanup proposal as well as ongoing cleanup and redevelopment work at the wood products campus.
Please direct any questions or comments to Danielle Berry at or by phone at (530) 284-1022.

Project Spotlight

The 2019/2020 winter season marked the beginning of a wood chip operation at the Indian Valley Wood Products Campus. Roughly 3,000 cubic yards of chips were obtained from a variety of sources including post-fire recovery efforts within the 2018 Camp Fire footprint and a wildland urban interface (WUI) hazardous fuels reduction project in Butterfly Valley.

Approximately half of these chips were used to fuel the biomass boiler at the Plumas County Human Health and Services Center, the remaining chips will be dried and stored for use in next year's operations. A special thanks to our collaborators; local contractor J&C Trucking, Plumas Fire Safe Council, and the USFS for supporting the advancement of biomass utilization in Plumas County.

As part of our efforts to advance the development of the Indian Valley  Wood Products Campus in Crescent Mills, the Sierra Institute has been navigating the pre-development hurdles associated with brownfield redevelopment and liability for the past five/six years. A number of site assessments have performed, demonstrating that there is some contamination soil–a typical scenario of any abandoned sawmill site. 

In September 2019 Sierra Institute initiated Phase I remediation ("cleanup") efforts focusing on three, 2-3 acre units located on the western portion of the site. Work completed to date includes excavation and on-site relocation of approximately 14,000 cubic yards (cy) of stockpiled wood waste, excavation of 2,000 cy of clean on-site fill from areas beneath the former stockpiles and placement over contaminated areas. The site was stabilized for the 2019/2020 winter season using hydro mulch, an environmentally friendly erosion control temporary ground cover. Additional clean fill material has been identified on-site and is scheduled to be placed during the summer of 2020.

The Sierra Institute is working closely with the U.S. Environmental Protection Agency and Plumas County to advance cleanup efforts and ensure the site is safe prior to redevelopment.
