Next month, on February 11 and 12, there will be a public meeting (via telephone) of the Clean Air Scientific Advisory Committee (CASAC). The purpose of the meeting is to discuss the Draft CASAC Report on EPA’s Integrated Science Assessment for Ozone and Related Photochemical Oxidants (External Review Draft – September 2019) and the Draft CASAC Report on EPA’s Policy Assessment for the Review of the Ozone National Ambient Air Quality Standards (External Review Draft).

On January 6, 2020, the EPA Administrator signed an Advance Notice of Proposed Rule (ANPR) soliciting pre-proposal comments on a rulemaking effort known as the Cleaner Trucks Initiative (CTI).
This ANPR describes EPA’s plans for a new rulemaking that would establish new emission standards for oxides of nitrogen (NOx) and other pollutants for highway heavy-duty engines. It also describes opportunities to streamline and improve certification procedures to reduce costs for engine manufacturers.
EPA is seeking input on this effort from the public, including all interested stakeholders. More information can be found at:
The U.S. Environmental Protection Agency has opened its fiscal 2020 round of funding for grants and rebates through its Diesel Emission Reduction Program (DERA). The Request for Applications, schedule for Information Session webinars, and other information can be found online at:
The purpose of this message is to inform you that the latest issue of the FHWA Air Quality and Sustainable Transport Highlights is now available.
The Highlights provide the latest news and information on transportation related air quality and sustainability activities, including information on transportation conformity, resiliency, and other related activities.
Items of interest in this issue include:
- FHWA Publishes the Mid-Point Applicability Determination for the CMAQ Traffic Congestion and CMAQ On-Road Mobile Source Emissions Measures
- FHWA Issues Implementation Guide on Nature-Based Solutions for Coastal Resilience
Past issues of the Air Quality and Conformity Highlights are available at: http://www.fhwa.dot.gov/environment/air_quality/conformity/highlights/
Past issues of the Sustainable Transport Newsletter are available at: https://www.fhwa.dot.gov/environment/sustainability/newsletter/index.cfm
The EPA has released the draft Policy Assessment (PA) regarding their review of the Ozone national ambient air quality standards (NAAQS). This draft document was prepared as part of the current review of the NAAQS for photochemical oxidants including ozone. The PA, when final, 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.
Availability of the draft PA was announced in the November 1, 2019 Federal Register (FR): https://www.govinfo.gov/content/pkg/FR-2019-11-01/pdf/2019-23888.pdf. The FR includes instructions on how to submit your comments regarding the draft PA. Comments regarding the draft PA should be received on or before December 16, 2019.
