  • Confronting allegations of air quality non-compliance

    A facility with an air quality permit must comply with all the conditions of that permit and demonstrate its compliance on an on-going basis. Unfortunately, no matter how diligently the facility and corporate staff strives to assure continuous compliance, unexpected compliance challenges can occur. For example, new equipment fails the emissions guarantees provided by equipment vendors; new staff ...

  • An operational model for vehicular pollution from a road network

    We present a brief review of the mathematical model CAR-FMI (contaminants in the Air from a Road, by the Finnish Meteorological Institute). The model has been developed for regulatory purposes, for predicting dispersion of pollution from a road network. It consists of an emission module, treatment of the meteorological time-series, an atmospheric dispersion module, and statistical analysis of the ...

  • A Neural Model for SPM Concentration Prediction in Coal Mines

    ABSTRACT Coal mines are the major sources of suspended particulate matter. To implement any control techniques or to install any control equipment around the coal mines, ambient concentration of suspended particulate matter should be known. In this paper a model is developed to find the concentration of suspended particulate matter at various locations away from the source. The model is ...

  • Controlling Railroad Smoke: An Historical Perspective on Regulatory, Educational, and Technological Options

    Control of pollutants from mobile sources has been a persistent problem for well over 100 years. While today’s focus is primarily on emissions from the internal combustion engine, before 1960, clean air crusaders considered the coal-burning steam locomotive the mobile source most affecting urban air quality.  The problem of controlling railroad smoke ...

  • Kuwait oil company streamlines emissions data management for corporate social responsibility and efficiency gains

    The Kuwait Oil Company (KOC) has long been a leader in addressing environmental sustainability issues. In the early 1990s, Kuwait faced the worst environmental catastrophe in recent history as a result of the bygone Iraqi regime's invasion of the country. Oil wells and gathering centers were ablaze and uncontrolled oil flow was filling hundreds of vast oil lakes and fouling mile after mile of ...

  • Asbestos Awareness: Preventing a Hazardous Workplace

    Many on-the-job hazards are obvious... leaking machinery... dangerous chemicals... slippery floors. However, other hazards aren't so obvious. There may be no visible signals that they are present at all. That's why Asbestos is often known as 'the silent killer.' While you often can't see, taste or smell it..., prolonged periods of exposure to Asbestos can cause lung disease, cancer... even death. ...


  • Combustible Dust: It Doesn’t Take Much

    A dust accumulation of 1/32 of an inch deep—about the thickness of a dime—covering just five percent of a room’s surface area doesn’t sound like much, but it’s enough to cause a catastrophic explosion, according to the National Fire Protection Association (NFPA). Although good engineering and safety practices to prevent dust explosions have existed for decades, there ...

  • Gas analysers support management of Swindon fire

    The capability to convene a multi-agency Air Quality Cell (AQC) was established in England in 2009 following the Buncefield Oil Storage Depot incident. A review of this event identified the need to rapidly co-ordinate the acquisition, analysis and interpretation of air quality data in major incidents. Arrangements have been made in England to bring together experts from the Environment Agency ...

  • Beware of Birds - Bill Read looks at the dangers and consequences of birdstrikes and the steps that airports and airside safety providers are taking to reduce the risk

    At 9.15 am on 29 April 2007, a Thomson Fly Boeing 757-200 with 221 passengers on board took off from Manchester airport on a flight to Arrecife, Lanzarote. Seconds after the aircraft had left the ground, two birds were sucked into the aircraft's right engine causing a flameout and black smoke to issue from the Rolls-Royce RB211-535E4 power plant. The pilot continued the takeoff on one engine and ...

  • Smart Series-Odor Management

    Tackling odors at composting facilities is a manageable task made simpler by inventorying and treating all sources and tapping into technology advances. Perhaps one of the most difficult realities that had to be faced 15 to 20 years ago by the composting universe is that the phrase, “odor-free” - at least when it comes to composting - is probably an oxymoron. Feedstocks that biodegrade within the ...
