  • Clean air research multi-year plan 2008-2012

    The Office of Research and Development’s (ORD) Multi-Year Plans (MYPs) describe what research ORD proposes to accomplish over the next 5-10 years in a variety of areas. The MYPs serve three principal purposes: to describe where the research programs are going, to present the significant outputs of the research, and to communicate the research plans within ORD and with stakeholders and clients. ...

  • Case Study - 95%+ solvent recovery to maintain clean air

    As environmental responsibility increases, more testing is being required. However, more testing means more extraction using organic solvents. To keep extraction solvents from adding to the complexity of keeping air clean, recovering the extraction solvent has become more common. BUCHI has stepped up to the challenge and met the concerns with the Syncore® Analyst. In addition to solvent ...

  • Return of the clean air interstate rule—The court does CAIR

    In summer 2008, the U.S. Court of Appeals for the D.C. Circuit issued a dramatic decision to vacate the Clean Air Interstate Rule (CAIR) in its entirety (North Carolina v. EPA, No. 05-1244, D.C. Cir., July 11, 2008). Following a petition for rehearing, it seems the previous vacatur was just a temporary detour, as the Court reinstated CAIR on December 22, 2008. The reinstatement appears to turn ...

  • Case study - Wind turbine manufacturer implements clean air initiative

    Overview When you think about generating electricity from wind, clean energy comes to mind. However, the wind turbine production process can be a major source of air pollution without the proper controls in place. Manufacturing and painting the blades, towers and nacelles requires composite construction material and solvent based coatings. The potential to emit Volatile Organic Compounds ...

  • Regulation of greenhouse gases under section 115 of The Clean Air Act

    Section 115 of the Clean Air Act, among the various options under the current act, may offer EPA the most effective, flexible, economically reasonable, and legally supportable means by which to regulate greenhouse gas emissions. The authors argue that Section 115, the section explicitly crafted to address international air pollution, has the potential to provide an appropriately flexible path ...

  • Bottom line on regulating greenhouse gases under the clean air act

    How can the EPA regulate GHGs? Doesn’t the Clean Air Act only apply to air pollutants? An April 2007 Supreme Court decision (Massachusetts v. EPA) ruled that GHGs are air pollutants under the Clean Air Act. The court instructed the EPA to decide whether GHG emissions endanger public health and/or welfare, or if current science is too uncertain to make a reasonable judgment. In response to the ...

  • Estimating the benefits of clean air contingent valuation and hedonic price methods

    This study deals with the estimation of willingness to pay for a 50% reduction of air pollution caused by road traffic in Rabat-Sale (Morocco) using contingent valuation and hedonic price methods. In the CVM, two techniques are employed. These are iterative bidding and dichotomous choice. Both empirical analyses are based on the same set of individuals. This strategy enables us to compare the ...

  • Radioactive Clean-up

    Radioactive, nuclear, or radiation clean-up is considered the most dangerous, difficult, and costly remediation activity after a nuclear disaster or accident.  The contamination may be found in the air, water, and soil, as wells as equipment and buildings (USEPA, 2010).Radioactive material, unlike most matter, is inherently unstable. Over time, the nuclei of radioactive atoms emit what's ...

  • Are Probiotics The Future Of Cleaning?

    Given the choice between a cleaner that reduces germs by 86% and one that all but eliminates them at 99.9%, which one would you choose? If you’re like most people, the answer appears simple – get rid of as many germs as possible. But those nearly 100% effective cleaners aren’t necessarily the best choice. Why? Because they kill all germs, good and bad. Probiotics are ...
