US EPA AERMOD Beta Released to US EPA Regional Offices

In December 2010, the US EPA released a beta version of the AERMOD model to US EPA Regional Offices for review. This release fully supports the new 1-hr NO2 and 24-hr PM2.5 NAAQS (National Ambient Air Quality Standards) as well as bug fixes within the Plume Volume Molar Ratio Method.

Modeling Tip

Compatibility of Some US EPA Models with 64-Bit Operating Systems

With the introduction of 64-bit processors and operating systems, some official US EPA model executables are no longer compatible with newer versions of Windows. These incompatibilities are present if the executable was originally compiled as a 16-bit application instead of a 32-bit application.

The table below lists some of the US EPA air dispersion models and their compatibility with 64-bit operating systems:



US EPA Executable Type

Description and Remarks




The original US EPA executable (ISCST3.EXE) is not compatible with 64-bit operating systems (O.S.).

Users of AERMOD View have access to the 32-bit recompiled executable (compatible with 64-bit O.S.) from the Preferences dialog (ISCST3_Lakes_32bit_02035.exe).

Info about the ISCST3 model:




This executable is compatible with 64-bit O.S.

The ISC-PRIME model is available under the AERMOD View interface.

Info about the ISC-PRIME model:




Although the original US EPA executable (AERMOD.EXE) is a 32-bit executable, this executable is not able to run in some Windows 7, 64-bit O.S.

Users of AERMOD View can select, from the Preferences dialog, a recompiled alternative version that will run in all Windows 7, 64-Bit O.S. (AERMOD_EPA_Win7_Comp.exe).

Info about the AERMOD model:

B.C., Washington State Sign Climate Action Partnerships

WASHINGTON - February 2, 2011 - A pair of climate action agreements between B.C. and Washington state will strengthen cross-border efforts to reduce carbon pollution while advancing the low- carbon economy.

B.C. Minister of State for Climate Action John Yap and Washington Department of Ecology Director Ted Sturdevant signed agreements on limiting carbon emissions from government operations and promoting awareness of the impacts of sea level rise on coastal areas.

EPA Proposes to Retain National Air Quality Standards for Carbon Monoxide / Air Monitoring Revisions Would Ensure People are Protected

WASHINGTON - January 31, 2011 - After a careful review of the best available science, the U.S. Environmental Protection Agency (EPA) is proposing to keep the current national air quality standards for carbon monoxide (CO), while taking steps to gather additional data through more focused monitoring. The science shows that the current standards will protect people, especially those susceptible to health problems associated with breathing CO from the outdoor air. CO can cause harmful health effects by reducing oxygen delivery to the body’s organs (like the heart and brain) and tissues. At extremely high levels, CO can cause death.

Experts Selected to Lead Oil Sands Monitoring

EDMONTON - January 27, 2011 - Twelve independent experts from across North America have been chosen to help create a world-class environmental monitoring system for Alberta’s oil sands.

“I am committed to ensuring we have a robust, credible, and transparent environmental monitoring, evaluation and reporting system in the province, beginning with the oil sands region,” said Rob Renner, Minister of Environment. “This extremely accomplished group of individuals, who have significant experience and wide-ranging expertise, will deliver on this important initiative.”

Leading the panel as co-chairs are Hal Kvisle and Howard Tennant. Both have extensive leadership experience. Kvisle is the former president and CEO of TransCanada Corporation, and Tennant is the former president and vice-chancellor of the University of Lethbridge. The remaining panel members represent a broad range of expertise from the scientific, academic, public administration, regulatory, and health fields.

Governments Work Together to Address Climate Change

January 7, 2011 - The governments of Canada and Ontario are addressing climate change together through the announcement of joint funding for the Ontario Regional Adaptation Collaborative (Ontario RAC), a series of projects to help communities adapt to climate change. The three-year initiative is aimed at helping decision-makers in Ontario better prepare for extreme weather impacts.

The Honourable Christian Paradis, Minister of Natural Resources stated that Natural Resources Canada provided $3.3 million of the $6.8 million in funding for the Ontario RAC. One goal of the collaborative is to help municipalities apply climate change considerations to decisions about water supplies or infrastructure, for example, in building code standards and water engineering practices.
