  • Proposed boiler MACT sets aggressive emission limits

    On June 4, 2010, U.S. EPA proposed National Emission Standards for Hazardous Air Pollutants (NESHAP) for industrial, commercial, and institutional boilers and process heaters at both major and area sources of hazardous air pollutants (HAP) emissions.  EPA proposed separate rules for units at major sources of HAP emissions (greater than 10 tons per year [tpy] of any single HAP and/or greater ...

  • Simplified mass balance method: An accurate way to track refrigerant emissions

    With the simplified mass balance method, current levels of harmful refrigerant gases or other chemicals that harm the environment, such as hydrofluorocarbons (HFCs) and chlorofluorocarbons (CHCs), can be calculated and work to better predict of future levels of accumulated emissions formulated. This emissions information enables environmental scientists and government regulators to better ...

  • General Air Sampling Guidelines (PDF)

    This Standard Operating Procedure (SOP) provides guidance in developing and implementing sampling plans to assess the impact of hazardous waste sites on ambient air. It presents the United States Environmental Protection Agency/Environmental Response Team's (U.S. EPA/ERT's) approach to air sampling and monitoring and identifies equipment requirements. It is not within the scope of this SOP to ...

  • Black Carbon – the elephant in the room!

    Traditionally, ambient particulates have been measured gravimetrically according to their size. However, in this article Jim Mills, Managing Director of Air Monitors, will demonstrate that the time has come to change or at least augment the way ambient particulates are monitored and regulated. Air Monitors has supplied most of the UK's ambient monitoring network, but Jim will explain why the ...

  • Is it better to burn or bury waste for clean electricity generation?

    The use of municipal solid waste (MSW) to generate electricity through landfill-gas-to-energy (LFGTE) and waste-to-energy (WTE)projectsrepresentsroughly14%ofU.S.nonhydrorenewable electricity generation. Although various aspects of LFGTE and WTE have been analyzed in the literature, this paper is the first to present a comprehensive set of life-cycle emission factors per unit of electricity ...

  • GHG regulation under the clean air act – recent developments

    EPA’s GHG Tailoring Rule and Senate Action On October 27, 2009, EPA published the Prevention of Significant Deterioration (PSD) and Title V Greenhouse Gas (GHG) Tailoring Rule in the Federal Register, followed by a 60-day public comment period that ended on December 28, 2009. The proposed rule represents EPA’s effort to decrease the number of sources subject to major source ...

  • Water Quality Models

    ' In order to determine the impacts of a particular discharge on ambient water quality, it is usually necessary to model the diffusion and dispersion of the discharge in the relevant water body. The approach applies both to new discharges and to upgrading of existing sources. This note provides guidance on models that may be applicable in the context of typical Bank projects.' Introduction ...

  • Independent verification demonstrates high value in the energy industry

    The current UK energy climate is one of movement and action. The latest high-impact report regarding climate change comes from Sir Nicholas Stern, former chief economist at the World Bank, who has produced the first in-depth paper on the economics of global warming. His predictions that unabated climate change could shrink the global economy by 20% have made industry sit up like nothing before. ...

  • NOW is the time for energy savings!

    NOW Is The Time for Energy Savings! You’ve been reading on-line, in journals, perhaps even in Environmental News for You and seen the arguments of why a climate change program is beneficial for your company: • proven reduction in operational costs;• opportunity to generate carbon credits for potential additional revenue;• create new, attractive products and re-package old ones;• use as ...


  • Common Treatment Technologies for Nonhalogenated VOCs

    Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated VOC-contaminated soil. Because a presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site, the presumptive remedy approach will accelerate site-specific ...

  • Pushing the Limits of Reengineering

    Cutting-edge turbine technology enables more efficient and cleaner power generation. However, the service of advanced gas turbines is challenging—especially when parts need to be replaced. The example of a blade replacement project shows how Sulzer establishes innovative reengineering processes and contributes to a secure energy supply that causes less carbon emission. A Sulzer ...

  • Questions and answers on the Commission Communication `Towards a Circular Economy` and the Waste Targets Review

    What is a circular economy? A circular economy preserves the value added in products for as long as possible and virtually eliminates waste. It retains the resources within the economy when a product has reached the end of its life, so that they remain in productive use and create further value. It may involve: Increasing the time products deliver their service before ...

  • Non-Ionising Radiation

    Pressures on the environment may occur through chemical, physical and biological agents. The subject of this study is physical agents, where physical fields are examined. Physical fields are part of the natural environment. Depending upon their properties and the surrounding conditions, physical fields are transmitted through the spaces in which we live, potentially affecting human health and ...

  • Implementing Cleaner Production

    ' Cleaner production (CP) should be an essential part of any comprehensive pollution management system, at an enterprise or national level. Significant reductions in pollution loads can often be obtained at little cost, and efficient use of resources and reduction in wastage in industrial production are clearly preferable to reliance on end-of-pipe treatment (EoP). Some firms -- the 'dynamic' ...


  • The New Environmental Insurance Products: When Does it Make Sense to Buy Them?

     Part One Introduction Real estate transactions with environmental problems often founder on attempts to shift the liabilities from one party to the other. In transactions with other types of problems, insurance is a popular risk transfer mechanism,  and is regularly used for that purpose, but it is used far less often when there are environmental risks. This so-called ...
