MacDonald, M., E. Thoma, R. Duvall, AND I. George. Next Generation Emission Measurements (NGEM) Advancements. "ORISE Meets the World” presentation series, RTP, NC, July 07, 2022.
Impact/Purpose:
On July 7, 2022, Megan MacDonald delivered a presentation titled “Next Generation Emissions Measurements (NGEM) Advancements” to EPA ORD’s “ORISE Meets the World” presentation series. This monthly seminar features presentations from EPA members of Oak Ridge Institute for Science & Education (ORISE) and an invited speaker from industry or academia, with a Q&A session after each speaker. In this talk Megan reviewed NGEM concepts and technical advancements through brief descriptions of several research efforts she has participated in as part of her ORISE experience. The discussion focused on EPA SPod fenceline sensor technologies, emerging commercial SPods, and a variation of the approach developed for leak detection inside of industrial facilities.
Description:
Abstract: Industrial facilities can emit hazardous air pollutants from fugitive leaks and process upsets that can go undetected for extended periods. A key to improved understanding and management of these sources lies in the development of Next Generation Emissions Measurements (NGEM) approaches that can detect emissions and enable efficacious mitigation strategies. This presentation reviews recent advancements in NGEM technologies through presentation of real-world field data acquired using EPA prototype and newly available commercial fenceline sensors. Advancements in near-source data analysis approaches using R-Shiny app are described. Use of these emerging NGEM tools to reduce near-source community exposures is discussed.
