U.S. EPA 11th Conference on Air Quality Modeling

On August 12th and 13th, the U.S. Environmental Protection Agency hosted the 11th Conference on Air Quality Modeling at its campus in Research Triangle Park, North Carolina. The conference served as the public hearing for proposed revisions to the Guideline on Air Quality Models (40 CFR Part 51 Appendix W). EPA staff presented an overview of the revisions and the public was afforded opportunity to give their own comments.

Audio recordings of conference proceedings, full transcripts, and copies of the presentations have been made available on the U.S. EPA’s SCRAM website. The EPA will accept comments on the proposed rulemaking through October 27, 2015. Formal comments can be submitted through the Proposed Rule Docket.

Modeling Tip

Reporting Individual Annual Averages from a Multi-Year Run in AERMOD

We previously discussed how AERMOD calculates long-term averages. In order to find the maximum annual average over a certain number of years, AERMOD had to be run separately for each year. That is no longer the case with the U.S. EPA’s recent update to AERMOD (version 15181). In the new version, modelers will find individual year annual average results in the Post-Processing Output File.

To enable this option in AERMOD View, follow the steps below:

Step 1. Open the Control Pathway window

Step 2. Select the Pollutant/Averaging options

Step 3. Enable the Annual averaging period

Step 4. Enable the Report Maximum Annual Average for Each Met Year option

Step 5. Go to the Meteorology Pathway window

Step 6. Add your multi-year surface (*.SFC) and profile (*.PFL) files.

Step 7. Finish setting up your project and run the model

The Report Maximum Annual Average for Each Met Year option automatically generates an annual average Post-Processing file for your model run.

** Maximum Annual Average POST file for Each Met Year

Upon successful model completion, the file will be displayed in the Plots Tree View under the Max Annual Average for Each Met Year heading. Use the Layer drop-down menu to choose which year you want contoured in the main display.

Layer Selection for the Post-Processing File

The file can also be opened in the Plot File Grid View to view the data in table format. The same Layer control allows the user to select which year is displayed.

From the Expat Blog, Decoding the Air Quality Index in Beijing

September 7, 2015- PWhen I moved to China in 2011, I was a pollution innocent. Sure, I had heard about China’s air pollution. I had even tasted it, - literally, in the late 1990s, when the air was full of black coal particles.

During my first few weeks living there, Beijing was going through a clean-air snap. I joked to my wife, Deb, who was then back in Washington, D.C., that the sky looked like Vermont’s. My apartment was so overheated that I left the window open to let in cool air.

EU Car Pollution Laws Have Improved UK's Air Quality, Say Carmakers

September 4, 2015 - Meeting strict new EU pollution standards has added £1,500 to the cost of every new vehicle, say carmakers who claim that because of European legislation to cut tailpipe pollution, Britain’s air quality is better now than it has been for centuries.

“New European emission limits, which apply to all new cars sold from this week, have the potential to all but eliminate exhaust pollutants that impact air quality,” said Mike Hawes, chief executive of the Society of Motor Manufacturers and Traders (SMMT).

Tests in Alberta Industrial Heartland Reveal Air Quality Concerns

August 30, 2015 - EDMONTON - New air-quality tests in one of Canada's largest petrochemical processing regions have revealed more evidence of short-lived but concentrated plumes of toxic chemicals.

The tests by a Nobel-prize-winning lab at University of California Irvine echo previous results scientists have recorded for known carcinogens in the area northeast of Edmonton.

MIT Analysis Improves Estimates of Global Mercury Pollution

August 21, 2015 - Once mercury is emitted into the atmosphere from the smokestacks of power plants, the pollutant has a complicated trajectory; even after it settles onto land and sinks into oceans, mercury can be re-emitted back into the atmosphere repeatedly. This so-called “grasshopper effect” keeps the highly toxic substance circulating as “legacy emissions” that, combined with new smokestack emissions, can extend the environmental effects of mercury for decades.

EPA Proposes New Measures to Cut Methane Emissions from the Oil and Gas Sector

August 18, 2015 - WASHINGTON - Continuing the Obama Administration’s commitment to take action on climate change and protect public health, the U.S. Environmental Protection Agency (EPA) is announcing commonsense proposed standards today that would reduce emissions of greenhouse gases (GHG) and volatile organic compounds (VOC) from the oil and natural gas industry. The proposal is a part of the Administration’s strategy under President Obama’s Climate Action Plan to cut methane emissions from the oil and gas sector by 40 to 45 percent from 2012 levels by 2025.

Methane, the key constituent of natural gas, is a potent GHG with a global warming potential more than 25 times greater than that of carbon dioxide. Methane is the second most prevalent greenhouse gas emitted in the United States from human activities, and nearly 30 percent of those emissions come from oil production and the production, transmission and distribution of natural gas.
