Proposed Urban Area Criteria for 2020 Census

On Friday, February 19, 2021, the proposal for the 2020 Urban Area Criteria was published in the Federal Register, https://www.govinfo.gov/content/pkg/FR-2021-02-19/pdf/2021-03412.pdf. Comments on the proposal are due on May 20, 2021. These urban area criteria will be important for determining, among other things:

  • Establishing boundaries for Metropolitan Statistical Areas (MSAs) and Micropolitan Statistical Areas (µSAs)
  • Transit funding amounts for the state and local communities
  • Areas that are or are not eligible for 5307 Urbanized Area funding and 5311 Rural Transit Funding

MOVES3 Now the Official Model; New Installer Resolves Problems with MOVES2014b

EPA posted MOVES3 on EPA’s website in mid-November.  With the publication of the MOVES3 Federal Register notice on January 7, MOVES3 is now the official version of MOVES.  MOVES3 has been updated and improved from the previous version in many ways.  The Federal Register notice begins the two-year conformity grace period which ends January 9, 2023.  Please see the notice and EPA’s MOVES3 Policy Guidance for more information on the use of MOVES3 and MOVES2014b for regulatory purposes.

Unrelated to the Federal Register notice, EPA is also posting a new MOVES2014b installer.  The new installer replaces MySQL with MariaDB as the database server for MOVES2014b. (MariaDB is already the database server for MOVES3). MariaDB continues to support features that MOVES relies on, whereas the latest versions of MySQL removed these features, which is causing issues for MOVES2014b. Using MariaDB resolves various problems that users have found with recent installations of MOVES2014b, including an error where some particulate matter (PM) emissions may be dropped with no error message, sometimes leading to low PM output from MOVES installed with MySQL 5.7.26 or later.  For these reasons, it is critical to reinstall MOVES2014b to eliminate this potential error when using this version of MOVES.

Modelers who installed MOVES3 had an option to reconfigure MOVES2014b to use MariaDB when they installed MOVES3.  Modelers who selected that (default) option during the installation do not need to do anything more; MOVES2014b will use MariaDB and will produce correct PM results.  However, MOVES2014b modelers who have not installed MOVES3, or who chose not to reconfigure MOVES2014b to use MariaDB when they installed MOVES3, should now use this new installer to update their MOVES2014b configuration.

The new MOVES2014b installer is available at https://www.epa.gov/moves/moves-versions-limited-current-use.  Simply download and double-click the installer executable and follow the on-screen instructions.

For other information on MOVES, please review the materials at https://www.epa.gov/moves.
