Emerald Kalama

We regulate water, hazardous waste, and cleanup activities at the Emerald Kalama Chemical plant.

Solid waste

Waste was found to not contain enough harmful chemicals to be considered hazardous

The comment period on our proposed decision to allow Emerald Kalama Chemical (Emerald) and Fire Mountain Farms (FMF) to change how they manage some of their waste ended Dec. 12, 2019. While state and federal law currently consider the waste to be “listed” as hazardous waste, the companies collected data shows it does not contain enough harmful chemicals to be considered dangerous.


Emerald and FMF submitted petitions to exclude (or “delist”) a one-time amount of up to 20,100 cubic yards of material containing trace amounts of benzene, toluene, and other chemicals from the list of federal hazardous wastes. In the events that led to this petition process, FMF mixed Emerald’s wastewater treatment plant sludge with treatment solids from other facilities and land-applied or stored the mixed material at its facilities.

How do we make this decision?

Step 1: The United States Environmental Protection Agency (EPA) held a comment period on its decision to grant the petitions. Visit https://www.federalregister.gov (Docket # EPA-R10-RCRA-2019-0662) for more infomration on the EPA's decision.

Step 2: We held a comment period on our proposed decision to approve the petitions. 

Read the comment notice for more information.

If approved, these petitions would allow the companies to manage the mixed material that is currently stored at three facilities owned and operated by FMF in Lewis County (Big Hanaford, Burnt Ridge, and Newaukum Prairie) as solid waste instead of hazardous waste.
