  • Qmax Ozone Presentation

    Ozone (O3) is an allotrope of oxygen, the molecule consisting of three oxygen atoms instead of the more stable diatomic O2 Ozone is a pale blue gas at standard temperature and pressure. It forms a dark blue liquid below -112 ºC and a dark blue solid below -193 ºC. Ozone is a powerful oxidizing agent. It is also unstable, decaying to ordinary oxygen through the reaction: ...


  • States propose attainment designations for the new 1-hour So2 NAAQS

    The U.S. EPA revised the primary National Ambient Air Quality Standard (NAAQS) for sulfur dioxide (SO2) on June 2, 2010 by implementing a new 1-hour standard of 75 parts per billion (ppb) (calculated as the three-year average of the 99th percentile of the annual distribution of daily maximum 1-hour average concentrations). Based on an evaluation of the risks posed by acute exposure to SO2, EPA ...

  • EPA clamping down on Ozone standards

    The U.S. Environmental Protection Agency (EPA) is preparing to again lower its ozone standard. This action reduces the amount of ozone that is allowed in the air we breathe and thus forces more industrial sources to further reduce their air pollution emissions. In this white paper we look at: What will happen when the new ozone standard is finalized; and Ways to deal ...

  • U.S. EPA Propses Revisions to Ozone NAAQS

    In May 2008, states, environmental groups, and industry groups filed petitions with the D.C. Circuit Court of Appeals (Court) for review of the 2008 ozone standards.  In March 2009, the Court granted a U.S. EPA request to stay the litigation so that the Obama administration could review the standards and determine whether they should be reconsidered. On September 16, 2009, U.S. EPA announced ...

  • Rethinking the California Air Resources Board`s ozone standards

    The California Air Resources Board (CARB), California’s state air-pollution regulatory agency, recently adopted the most stringent ozone air-pollution standard in the United States. Attempting to attain the new standard will impose great hardship on Californians in exchange for small and imperceptible health benefits.By CARB’s own estimates, the incremental benefits of attaining its new ...

  • `Challenges Facing Facilities in 8-Hour Ozone and/or PM2.5 Nonattainment Areas,` presented at the 2005 TAPPI Environmental conference

    Abstract In 2004, U.S. EPA finalized designations under the 8-hour ozone standard and the fine particulate matter :'PM:...) standard. With respect to the 3-hour ozone standard, 474 counties or partial counties were designated as nonattainment, while 30 areas volunteered to enter Early Action Compacts (EAC). U.S. EPA designated 40 areas comprised of 210 counties and the District of Columbia ...

  • A Different Way of Looking at Ozone

    Ozone, a tri-oxygenated molecule, is known to act as a shield to protect us from the sun’s harmful rays.  As this innocent molecule plummets to the lower elevations on its journey to our hometowns, it meets hydrocarbon vapors and oxides of nitrogen (bad company), is exposed to sunlight and temperature (bad influence), and becomes a culprit and villain named photochemical smog or bad ozone. ...


  • Ozone Depleting Substances

    Abstract In Europe the increase in ultra-violet radiation (UV) is estimated to be larger over the western parts because of large depletion in the total ozone column. UV global trends are estimated to increase by 3-4% per decade in northern hemisphere midlatitudes and 3-9% in southern hemisphere midlatitudes. The ozone layer can start recovering, but full recovery will take another 50 years if ...
