Senate Bill 726 has been introduced into the 83rd Oregon Legislative Assembly which would address municipal solid waste landfills.
The Bill would require the owner or operator of a municipal solid waste landfill to conduct surface emissions monitoring and report data as specified to the Oregon Department of Environmental Quality.
The Oregon Environmental Quality Commission would be required to establish rules for surface emissions monitoring and mitigation of methane gas emissions from municipal solid waste landfills.
By July 1, 2026, an owner or operator of a municipal solid waste landfill would be required to conduct surface emissions monitoring to:
- Use advanced methane detection technology to conduct surface emissions monitoring above all areas of the surface of the landfill.
- Report results, including specific information to the Oregon Department of Environmental Quality.
- Maintain records for at least five years.
- Remonitor after taking corrective action within 10 days of any exceedance; and submit a mitigation plan to the Oregon Department of Environmental Quality for approval if the owner or operator cannot take corrective action because the exceedance is located within the active or working face of the landfill.
