  • QuadOa and OGI: how EPA regulations are changing the way we look at gas leaks

    Earlier this year, the Environmental Protection Agency (EPA) published Regulation 40 CFR, Part 60, Sub-part OOOOa, commonly known as Quad Oa, and finally brought optical gas imaging (OGI) firmly into the mainstream. This presents a major shift in the way fugitive emissions are regulated, and the technology that can be used.  Detecting and acting on gas leaks is naturally a major ...

  • EPA studies identify techniques for critical leak testing prior to soil-vapor sampling

    Researchers at EPA’s National Risk Management Research Laboratory (NRMRL) in Ada, OK, are developing quality assurance (QA) measures for soil-gas and sub-slab sampling methods that help differentiate contaminant vapors due to vapor intrusion from background sources. Recent research focused on measures to identify leakage of ambient air into conventional vapor probes, which can significantly ...

  • Proper Monitoring Essential to Reducing ‘Fugitive Emissions` Under Leak Detection and Repair Programs

    The Clean Air Act requires refineries to develop and implement a Leak Detection and Repair (LDAR) program to control fugitive emissions. Fugitive emissions occur from valves, pumps, compressors, pressure relief valves, flanges, connectors and other piping components. Comparison monitoring conducted by the U.S. Environmental Protection Agency's (EPA) National Enforcement Investigation Center ...
