  • Inhalation Health Risk Assessment of Air Toxic Emissions from Large Combustion Turbine Power Projects

    Power generation from combustion turbine projects continues to grow throughout the world. With natural gas as the most common primary fuel, and low-sulfur #2 oil as the backup fuel, combustion turbines are among the cleanest forms of fossil power generation. This paper discusses the results of a preliminary inhalation health risk assessment of air toxic emissions from four power plant ...

  • U.S. EPA Promulgates Final Air Toxics Standards for Compression Ignition Reciprocating Internal Combustion Engines (RICE)

    On March 3, 2010, U.S. EPA promulgated final National Emissions Standards for Hazardous Air Pollutants (NESHAP) for existing compression ignition (CI) stationary Reciprocating Internal Combustion Engines (RICE) that were not previously regulated by the existing, so called, RICE MACT (i.e., 40 CFR Part 63, Subpart ZZZZ).  The RICE MACT rule was originally promulgated in 2004.  The March ...

  • 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 ...

  • Criteria and Air-Toxic Emissions from In-Use Automobiles in the National Low-Emission Vehicle Program

    The U.S. Environmental Protection Agency (EPA) implemented a program to identify tailpipe emissions of criteria and air-toxic contaminants from in-use, lightduty low-emission vehicles (LEVs). EPA recruited 25 LEVs in 2002 and measured emissions on a chassis dynamometer using the cold-start urban dynamometer driving schedule of the Federal Test Procedure. The emissions measured included regulated ...

  • The Wait Is Over; The New Boiler MACT Is Here

    The Wait Is Over; The New Boiler MACT Is Here    April 29, 2010 was a busy day for U.S. EPA and marked the culmination of months and years of background effort and planning related to air toxic emissions from boilers.  U.S. EPA has released pre-publication versions of four (4) proposed rules on their website that, when finalized, will impact thousands of ...

  • Estimation of HAP Emissions from Oil and Gas E&P Operation Wastes

    Wastes generated from oil and gas Exploration and Production (E&P) operations contain chemicals that are considered as toxic air pollutants for the purpose of toxic release inventories (TRI) reports or hazardous air pollutants (HAP) under Title III of the 1990 Clean Air Act Amendments. A study was conducted to estimate HAP emissions from E&P waste management operations on a per-event basis. The ...

  • Fact sheet: EPA mercury rules and power reliability

    New rules from the U.S. Environmental Protection Agency to reduce mercury and other toxic air emissions will affect dozens of antiquated power plants currently operating without pollution controls. These rules have stirred debate in some circles as to whether retrofitting or retiring outdated plants will cause shortfalls in electricity capacity. How will EPA mercury rules influence the ...

  • Air Rule for Cement Kilns Requires 92 Percent Cut in Mercury Emissions

    Portland cement kilns will be required to reduce emissions of mercury by 92 percent as part of an Environmental Protection Agency final rule announced Aug. 9 that imposes controls for several toxic pollutants. Although most of the emissions standards in the final rule are less stringent than what the agency had proposed in 2009, the cement industry said the cost to operate the required controls ...
