U.S. EPA Updates the CALPUFF Modeling System

On December 4, 2013, the U.S. EPA announced the immediate availability of updated versions of CALPUFF and CALMET (version 5.8.4, level 130731). These executables replace CALPUFF and CALMET version 5.8 (level 070623) as the "EPA-Approved" versions. This update does not affect CALPOST.

The updates include numerous bug fixes previously implemented by the model developers but never approved by the EPA. More information including a detailed report summarizing each bug fix can be found on the Support Center for Regulatory Atmospheric Modeling website.

Lakes Environmental is working on a new version of CALPUFF View that will incorporate these changes.

CALPUFF View users can refer to this month’s Modeling Tip for instructions on using the new executables in their existing software.

Modeling Tip

How to Change Executables in CALPUFF View

The CALPUFF modeling system executables are distributed by the model developer, TRC. Lakes Environmental’s CALPUFF View software is designed to allow users to easily install these executables. However, there may be situations where users want to use different executables. For example:

  • A custom recompiled version may be required to support large projects by expanding parameter limits (e.g., number of sources, larger computational grids, etc.).
  • A specific version of CALPUFF may be stipulated in a modeling plan or permit application.
  • Users may want to make their own changes to the model code for testing purposes.
  • As mentioned earlier in the newsletter, new versions of CALPUFF and CALMET were recently approved by the U.S. EPA. Users can insert the new executables into CALPUFF View in the interim while our developers work on a new release of CALPUFF View.

Users will find it easy to run CALPUFF View using new or customized model executables. Simply complete the following steps to change the executable being used:

  1. Open the File menu and select Preferences. Many different program settings can be set here.
  2. The various models available in CALPUFF View are listed under the EPA Models/Limits section. Select CALPUFF.

  3. Select the User-Specified radio button and use the Specify File button to search your computer for the desired executable.

  4. Specify the Parameters File for the user-specified model executable.

The below screenshot shows the new CALPUFF version 5.8.4 incorporated into CALPUFF View using the User-Specified executable. Changing other model executables follows the same process; simply select the desired model (e.g., CALMET, CALPOST) from the same Preferences menu.

Ending Coal for Cleaner Air in Ontario

November 25, 2013 - Ontario is introducing legislation today that, if passed, would eliminate coal-fired generation as a source of electricity.

The proposed Ending Coal for Cleaner Air Act would ensure that once coal facilities stop operating by the end of 2014, coal burning generation on the electricity grid will never happen again. This would help ensure the public health and climate change benefits of ending coal-fired electricity are protected.

EPA Proposes 2014 Renewable Fuel Standards

November 15, 2013 - WASHINGTON - The U.S. Environmental Protection Agency (EPA) today proposed for public comment the levels of renewable fuels to be blended into gasoline and diesel as required by Congress under the Energy Independence and Security Act of 2007. Developed with input from the U.S. Department of Energy and U.S. Department of Agriculture, the proposal seeks public input on annual volume requirements for renewable fuels in all motor vehicle gasoline and diesel produced or imported by the United States in 2014. The proposal seeks to put the Renewable Fuel Standard (RFS) program on a steady path forward – ensuring the continued long-term growth of the renewable fuel industry – while seeking input on different approaches to address the “E10 blend wall.”
