  • Air emissions impact measurements at a perchloroethene remediation site

    As part of an U.S. EPA time critical removal action, an air monitoring system was established to measure real-time impacts of perchloroethene (PCE) on the surrounding areas. The soils and groundwater beneath the site (located in West Fargo, North Dakota) were treated using in situ heating of soil and groundwater, with the produced vapors collected using conventional vapor extraction. In order ...

  • Clearing the Air: Reducing upstream Greenhouse Gas Emissions from U.S. Natural Gas Systems

    Key findings: 1) Fugitive methane emissions from natural gas systems represent a significant source of global warming pollution in the U.S. Reductions in methane emissions are urgently needed as part of the broader effort to slow the rate of global temperature rise. 2) Cutting methane leakage rates from natural gas systems to less than 1 percent of total production would ensure that the climate ...

  • Panelboard emission control: An historical perspective

    Sometimes the best view of the future can be seen from the past. That's why we've written this paper. We believe that an understanding of the history of emission controls in the panelboard industry will help everyone understand how this industry got to where it is and what the future holds. This account focuses on the evolution of technology devoted to the control of air pollution emissions from ...

  • Modeling emissions from offshore drilling

    To regulate drilling activities proposed by oil and gas companies in the oil-rich Gulf of Mexico (GOM), governing agencies require the submittal and approval of certain plan documents before drilling activities can be initiated. For drilling activities in the Western GOM, these plans typically consist of one of the following: EP, or Exploration Plan – required to conduct ...

  • Case study - Flexographic printer: efficient emissions

    Problem Control of air emissions has become an important issue that flexible packaging converters must consider when changing or upgrading equipment. Robbie Manufacturing of Lenexa, KS, a producer of printed shrink films, bags and pouches for a diverse range of applications, addressed its emissions in 1991 and 1996 by investing in two catalytic oxidizers to control the EPA-regulated air ...

  • Turning back the tide - Remaking the EPA

    Stressing the importance of scientific integrity and transparency, EPA Administrator Lisa P. Jackson last month called for key changes to the process for reviewing National Ambient Air Quality Standards (NAAQS) to protect human health and the environment. 'It’s essential that the best science and the greatest transparency inform air quality standards that prevent illness and save lives,' said ...

  • EPA isues GHG BACT guidance

    Beginning in 2011, major sources of greenhouse gas (GHG) emissions that trigger Prevention of Significant Deterioration (PSD) permitting must implement Best Available Control Technology (BACT) for GHG emissions from new and modified sources. EPA has issued a variety of guidance in an attempt to clarify the BACT determination process for GHG emissions from common stationary sources:1 EPA’s ...

  • Technology: clean air’s unsung hero

    Last year, we celebrated the 40th anniversary of the U.S. Clean Air Act (CAA) and the 20th anniversary of the 1990 Amendments to the CAA. The CAA has been a huge success. From 1990 to 2008, emissions of six common pollutants were down 41%, while gross domestic product grew 64%. Emissions of volatile organic compounds dropped 31%, carbon monoxide dropped 46%, and sulfur dioxide dropped 51%. Lead ...

  • EPA shifts PM2.5 PSD permitting policies

    On August 12, 2009, EPA created a significant stir in the regulated community when it issued an order that signals a significant shift in how the agency intends particulate matter with a diameter less than 2.5 micrometers (PM2.5) emissions to be regulated under the Prevention of Significant Deterioration (PSD) program. The order specifically applied to petitions filed by environmental groups ...

  • Vapor-Phase Biofilters Show Promise for Treating High VOC Emissions.

    Evaluating the Feasibility of Natural AttenuationUsing natural attenuation to remediate organic compounds in groundwater has gained popularity. In some cases, this process can reduce contaminant levels to below risk-based corrective action criteria or regulatory standards without implementing additional remedial action alternatives. However, it is often difficult to prove that natural ...


  • 5 Reasons why it’s (still) important to reduce fugitive methane emissions

    The U.S. Environmental Protection Agency (EPA) recently released its annual greenhouse gas (GHG) inventory report. Using new data and information, the EPA lowered its estimate of fugitive methane emissions from natural gas ...
