Closure plan approved
We approved the final closure plan for Emerald Kalama Chemical (Emerald) and Fire Mountain Farms (FMF) to remove delisted hazardous waste from three facilities owned and operated by FMF in Lewis County. This plan outlines how the companies will remove and properly dispose of any wastewater, solids, and contaminated soil during cleaning of the three storage facilities.

Waste material
Waste was found to not contain enough harmful chemicals to be considered hazardous
In the spring of 2020, we approved petitions filed by Emerald and FMF in 2018 to change how they manage waste being stored at three locations in Lewis County. The final decision occurred following a public review and comment period that ended Dec. 12. 2019. While state and federal law currently consider the waste to be “listed” as hazardous waste, the companies collected data that shows it does not contain enough harmful chemicals to be considered dangerous.
If the petitions are granted, the mixed material will be moved out of Lewis County to a permitted municipal solid waste landfill. There are no landfills currently operating in Lewis County.
The mixed material currently located at the three locations in Lewis County is categorized as hazardous waste. However, tests show that the trace levels of benzene, toluene, and other chemicals are beneath human health and environmental threshold levels. This is why the material is eligible to be delisted as a hazardous waste. The material will be tested again to reconfirm these findings before it can be reclassified as a solid waste and moved to a solid waste landfill.
No, the mixed material is not biosolids. It is defined as a hazardous waste and ceased being biosolids as soon as it was mixed with industrial sludge.
Facility information
Emerald Kalama began operating an organic chemical plant in 1962 and currently has about 215 employees at it's Kalama plant. It processes toluene into chemicals for food, flavor, fragrance, and pharmaceutical industries.
- It produces about 194,000 tons of chemicals each year.
- Wastewater from the chemical-making process is treated and sent to the Columbia River. This makes up approximately 2 percent of all the wastewater from this facility.
