Today’s Federal Register – DFW TCM Substitution Notice

On December 12, 2019, the NCTCOG Regional Transportation Council adopted a resolution to substitute SIP-approved IH 35E/IH 635 HOV lane TCMs for traffic signalization project TCMs to offset any NOx and VOC emission reduction credits lost by removing these corridors from HOV lane usage and keep equivalent emission reduction controls in place. EPA’s Notice of Administrative Change (NOAC) has been published in today’s Federal Register to complete the TCM substitution process. The substitution is already in effect with issuance of EPA’s February 21, 2020 concurrence letters to NCTCOG & TCEQ, today’s NOAC revises the approved Texas SIP under 40 CFR 52 to reflect the substitution.

The published NOAC can be found at: https://www.govinfo.gov/content/pkg/FR-2020-06-17/pdf/2020-10835.pdf

EPA releases final Policy Assessment for the Ozone Standard Review

EPA has released the Final Policy Assessment for the Ozone National Ambient Air Quality Standards (PA, EPA–452/R–20–001). This document was prepared as part of the current review of the national ambient air quality standards (NAAQS) for photochemical oxidants including ozone (O3). The PA serves to “bridge the gap” between the currently available scientific and technical information and the judgments required of the Administrator in determining whether to retain or revise the existing O3 NAAQS. The primary and secondary O3 NAAQS are set to protect the public health and the public welfare from O3 and other photochemical oxidants in ambient air.

The final PA is available here: https://www.epa.gov/naaqs/ozone-o3-standards-policy-assessments-current-review

Proposals to test AERMOD Source Types RLINE and RLINEXT; DUE July 13, 2020

The purpose of this message is to request your assistance in soliciting proposals from State Departments of Transportation (DOTs), to test two new source types: RLINE and RLINEXT in AERMOD, an air pollution dispersion model, using real or hypothetical project examples and input data, and to create case studies.  Please forward this information to the appropriate staff at your State DOT.

Please see the this linked document for more information regarding this solicitation.

Agencies interested in participating in this effort are asked to submit a proposal to Victoria Martinez ([email protected]) and Cecilia Ho ([email protected]) with FHWA’s Office of Natural Environment and copy their respective FHWA Division Office by July 13, 2020.

An informational webinar for potential applicants will be held on June 2, 2020 at 1:00 ET. To attend, please visit https://connectdot.connectsolutions.com/newsourcetypetesting/.
