EPA Revises Policy on Development/Adoption of Interpollutant Trading Provisions for PM2.5


New guidance from the U.S. EPA resulted in changes to the policy set forth in the 2008 PM2.5 New Source Review Implementations Rule.

In specific, ratios provided in the preamble to the 2008 final rule are no longer supported for adoption in state implementation plans containing nonattainment NSR programs for PM2.5. In its place, states must provide technical demonstration that shows the net air quality benefits for any ratio involving PM2.5 precursors.

The memo provides detailed background on the issue and general guidance for developing PM2.5 precursor offset ratios.

Visit the US EPA website to read the full Memorandum.

Modeling Tip

Create Project Backup with Lakes Software Products

Performing an air dispersion modeling analysis often results in the creation of many files on your computer. Besides input and output files, projects can contain numerous meteorological data, terrain data, digital basemaps, and external data files. Whether you are modeling a simple scenario with AERMOD or a complex regional study with CALPUFF, there will be many different file types to account for and manage.

While working on your project, it is often desirable to back up your work for a variety of reasons. Creating a single Backup project file provides the following benefits:

  • Simplifies the transfer of files between computers or across the network
  • Simplifies the transfer of electronic files to the client or regulatory agency
  • Provides peace of mind knowing you have a complete project backup if restoration is ever needed
  • Provides an efficient means of storing and managing projects
  • Provides an alternate means for managing complex projects and archiving iterative runs to document inputs and results

To make this process easy, Lakes Environmental Software products include a convenient Backup option to gather your project files into a single archive. See detailed steps below:

Step 1: To backup the files from any Lakes Environmental software product, select the menu option File | Backup | Save to ZIP. You will be prompted to specify the location where the backup file (*.zip) should be saved. The zip file can be saved locally or on a network drive.

Step 2: After assigning a name to the backup file, the Backup Options dialog will appear. This dialog allows you to specify which files will be included in the archive. It is best to include as many files as possible, but you may wish to exclude large files such as terrain maps.

Step 3: You can also add additional files to your backup by pressing the Add Files or Add Folder buttons.

Step 4: Click OK when done.

Sending Project Files to Technical Support:

The Backup option is also extremely useful for sharing a project with our technical support team. Projects are often requested to help when troubleshooting support issues. Emailing the backup file to technical support when you first contact the team ( will save time and result in an even quicker turnaround time on support requests.

Submit Your Modeling Tip Today!

We are currently accepting submissions for the Monthly Modeling Tip section that appears in our newsletters. If you have a modeling tip that may benefit our readers, please send it to us at Your name and the name of your organization will appear below the tip providing you with an opportunity for increased exposure.

Canada's Environment Minister Announces Integrated Plan for Oil Sands Monitoring

July 21, 2011 - Canada's Environment Minister, the Honourable Peter Kent, released an integrated, world-class monitoring plan for the oil sands region today. The Government of Canada will be working with the Province of Alberta on implementing the plan.

"The oil sands represent a significant, long-term economic advantage for the people of Alberta, and all Canadians," said Minister Kent. "We must ensure that this resource is developed in a way that protects our air, our water and biodiversity for generations to come."

The Government of Canada coordinated the development of the monitoring plan in collaboration with provincial, territorial and academic scientists. This final plan includes components for monitoring air quality, biodiversity, and the next phase of water quality monitoring in the oil sands region.

EPA Opens Public Comment on Secondary Air Standards for Nitrogen and Sulfur Oxides/ Agency Announces Pilot Field Study on Environmental Impacts

WASHINGTON - July 13, 2011 - After a careful review of the best available science, the U.S. Environmental Protection Agency (EPA) is proposing secondary air quality standards to protect the environment from nitrogen oxides (NOx) and sulfur oxides (SOx). Today’s proposal builds on EPA efforts already underway to reduce NOx and SOx emissions.

EPA has made significant progress in developing a multi-pollutant standard that would protect vulnerable ecosystems, including streams and lakes. To ensure any updated standard is effective, EPA is planning to conduct a field pilot program to collect and analyze additional data and information.

Commission Proposes to Cut Sulphur Dioxide Emissions from Shipping by 90%

BRUSSELS - July 15, 2011 - Better air quality is on the way, thanks to proposals from the European Commission to lower the sulphur content of shipping fuels. The proposals should reduce sulphur dioxide emissions by up to 90 %, and fine particle emissions by up to 80 %. The benefits for public health will be between EUR 15 and 34 billion, far exceeding the expected costs, which are in the range of EUR 2.6 to 11 billion. With nearly half of Europe's population living in areas where EU air quality objectives are still not met, air pollution is one of the main environmental worries facing citizens.

“Environment Commissioner Janez Potocnik said: "Air pollution does not stop at borders. Land sources have been subject to the attentions of regulators for some time, and the time has now come for the maritime sector to deliver its fair share, all the more so as the impacts on air quality are felt far beyond coastal areas. This proposal is an important step forward in reducing air emissions from the fast-growing maritime transport sector. It will help resolve the persistent air quality problems that continue to affect millions of Europeans. It is part of a transformational agenda that will prepare the sector for the challenges of tomorrow."

Canada Working to Address Emissions from Heavy-duty Vehicles

August 9, 2011 - Today, the Honorable Peter Kent, Canada's Environment Minister, released a consultation paper on the development of proposed regulations to limit greenhouse gas emissions from new on-road heavy-duty vehicles. Canada and the United States are taking a common North American approach and Canada intends to implement regulations with the 2014 model year in alignment with the United States.

"We are moving forward with our sector by sector approach to reduce greenhouse gas emissions in coordination with the United States," said Minister Kent. "Building on our successful collaboration with the United States on the development of common North American standards for light-duty vehicles, we are also working together to do the same for heavy-duty vehicles."

This consultation paper is intended to provide another opportunity for interested parties to submit early comments prior to publishing proposed regulations in Canada Gazette Part I. Proposed regulations are targeted for publication in Canada Gazette Part I early in 2012 for a 60-day comment period.

EPA Proposes Criteria to Waive Federal Requirements for Capturing Gasoline Vapors When Refueling Vehicles/Part of Obama Administration’s Initiative to Remove Burdensome Regulations

WASHINGTON - July 11, 2011 - The U.S. Environmental Protection Agency (EPA) is issuing a proposal under the Clean Air Act that would waive requirements for systems used at gas station pumps to capture potentially harmful gasoline vapors while refueling cars. The proposal is part of the Obama Administration’s initiative to review outdated and redundant rules and ensure that regulations are beneficial without being unnecessarily burdensome to American businesses.

Beginning in 2013, states that meet the new criteria would have the option to do away with vapor recovery systems at the pump since an estimated 70 percent of all vehicles will be equipped by then with on-board systems that capture these vapors. The result of the proposal would be the continued protection of air quality and public health while potentially saving affected gas stations more than $3,000 annually.
