On November 9 and 10, 2020, Eastern Research Group, on behalf of EPA, hosted a virtual Optical Gas Imaging Stakeholder Workshop to gather information from stakeholders prior to promulgating procedures for the use of optical gas imaging OGI for leak detection with a focus on leak detection in the refinery sector. Below are links to the agenda and slides for presentations given during the workshop.
