This guidance document provides technical considerations for two options that grant recipients can use to identify or develop GWP threshold values in accordance with the EPA Interim Determination. It also details FHWA’s engagement with industry to identify industry average information.

On Wednesday, December 11, 2024 from 12:30 to 2:30 pm ET, FHWA will host a webinar that will provide an overview of the asphalt and concrete GWP threshold values and include presentations from asphalt and concrete industry representatives discussing data provided to inform the thresholds.
