Hazardous Substance Storage Reporting

A hazardous substance is any substance required by Oregon OSHA to have a safety data sheet (SDS), or any substance for which a hazard is identified on any available SDS. It includes radioactive material or any waste substance that presents a physical or health hazard to emergency response personnel or the public under normal conditions of use or during an emergency situation. If the maximum amount of a hazardous substance stored at the site meets or exceeds the reportable quantity at any one time for more than 24 hours, it must be reported. 

Oregon is a one-stop shop for hazardous substance reporting. By submitting an annual hazardous substance inventory report, to CHS Manager, the facility has fulfilled the obligation to report. The Local Emergency Planning Commission (LEPC), fire department, and EPA has access to the information in the report. We worked diligently to streamline the process for facilities to report their hazardous substance storage and distribute the information to agencies privy to the information. 

The Oregon State Fire Marshal (OSFM) works directly and indirectly with the local fire department and responding hazmat team to ensure first responders are informed and prepared to respond to a hazardous substance incident. We work with the Oregon State Emergency Response Commission (SERC) and the LEPC in the planning for emergency responses. These collaborations benefit all of Oregon with better planning and preparedness for a quick and efficient response in an emergency.

CHS Manager - File a Hazardous Substance Inventory Report

The Community Right to Know Hazardous Substance Manager (CHS Manager) is the online portal for Oregon facilities to submit an annual hazardous substance inventory reports. Any facility that stores a hazardous substance at a reportable quantity is required to submit an annual report for the substances stored during the previous calendar year. Any facility that introduces a new hazardous substance, in a reportable quantity, at any location must file a report within 30 days.

Safety Data Sheets (SDS)

To ensure emergency planners, first responders, and the public have the most up-to-date and accurate information available, facilities are required to upload the current SDS to the CHS Manager for each reported hazardous substance.
