Modeling Tip

AERMOD View: Counting Exceedances with Flagpole Heights

AERMOD modelers have long been able to determine where a threshold is being exceeded by using the MAXIFILE output file. AERMOD View users will recognize this option as the Threshold Violation File in the Output Pathway. When a Threshold Violation File is added to a project in AERMOD View, the program automatically creates a plot file which counts the number of exceedances at each receptor.

With Version 7.6.1, you can see separate exceedance calculations for flagpole receptors that fall on top of ground-level receptors (i.e., receptors with the same [X,Y] coordinates but measure concentration at different heights).

To add flagpole heights to receptors:

  1. Open the Receptor Pathway options

  2. In the Receptor Summary, select Yes for the Flagpole Receptors option. You can also specify a Default Height above ground for all receptors.

  3. To add a flagpole height to a specific discrete receptor, enter the desired height in the Flagpole Heights [m] (Optional) column of the Discrete Cartesian receptor options. Any receptors that do not contain a flagpole height will use the Default Height from the Receptor Summary.

Once the Threshold Violation File has been specified, you can run the model. In the Plots tab of the Tree View, you’ll find a folder named Exceedance. Select the exceedance file and click on the View as Grid button to view the exceedances. The table is sorted in descending order of number of exceedances, but you can click on the heading of any column to sort by a different parameter.

Each flagpole height receptor is treated as a unique location, so you can differentiate between exceedances at two different measurement heights.

Canada-Alberta Oil Sands Monitoring Program Well Underway

FORT MCMURRAY, Alberta – July 16, 2012 - Today, Canada’s Environment Minister Peter Kent, and Alberta’s Environment and Sustainable Resource Development Minister Diana McQueen toured several of the new oil sands monitoring stations now in place in the early stages of implementation of the Joint Canada-Alberta Implementation Plan for Oil Sands Monitoring.

The Joint Canada-Alberta Implementation Plan for Oil Sands Monitoring, announced by Minister Kent and Minister McQueen in February, commits to a scientifically rigorous, comprehensive, integrated, and transparent environmental monitoring program for the region. It outlines the path forward to enhance the monitoring of water, air, land and biodiversity in the oil sands by demonstrating how we will sample more sites for more substances more frequently. The program is designed to provide an improved understanding of the long-term cumulative effects of oil sands development.

EPA Greenhouse Gas Permitting Requirements Maintain Focus on Largest Emitters

Washington - July 3, 2012 - The U.S. Environmental Protection Agency (EPA) today announced that it will not revise greenhouse gas (GHG) permitting thresholds under the Clean Air Act. Today’s final rule is part of EPA’s common-sense, phased-in approach to GHG permitting under the Clean Air Act, announced in 2010 and recently upheld by the U.S. Court of Appeals for the D.C. Circuit. The final rule maintains a focus on the nation’s largest emitters that account for nearly 70 percent of the total GHG pollution from stationary sources, while shielding smaller emitters from permitting requirements. EPA is also finalizing a provision that allows companies to set plant-wide emissions limits for GHGs, streamlining the permitting process, increasing flexibilities and reducing permitting burdens on state and local authorities and large industrial emitters.

South Africa Establishes National Ambient Air Quality Standard for Particulate Matter with Aerodynamic Diameter Less Than 2.5 Micron Meters

June 29, 2012 - The Minister of Water and Environmental Affairs, Ms Edna Molewa today, 29 June 2012 published under the National Environmental: Air Quality Act, 2004 (Act No. 39 of 2004), the National Ambient Air Quality Standard for particulate matter with aerodynamic diameter less than 2.5 micron meters in Gazette No. 35463.

Particulate air pollutants comprise material in solid or liquid phase suspended in the atmosphere. Such particles can be either primary (i.e naturally occurring) or secondary (human activities-related) and cover a wide range of sizes. Naturally occurring particulate matter originates from dust storms, forest fires and sea spray. Human activities, such as the combustion of fossil fuels, motor vehicles' tailpipes and various industrial and non-industrial processes, generate significant amounts of particulate matter.

EPA Proposes Clean Air Standards for Harmful Soot Pollution

WASHINGTON - June 15, 2012 - In response to a court order, the U.S. Environmental Protection Agency (EPA) today proposed updates to its national air quality standards for harmful fine particle pollution, including soot (known as PM2.5). These microscopic particles can penetrate deep into the lungs and have been linked to a wide range of serious health effects, including premature death, heart attacks, and strokes, as well as acute bronchitis and aggravated asthma among children. A federal court ruling required EPA to update the standard based on best available science. Today’s proposal, which meets that requirement, builds on smart steps already taken by the EPA to slash dangerous pollution in communities across the country. Thanks to these steps, 99 percent of U.S. counties are projected to meet the proposed standard without any additional action.
