Scope: (1) The objective would be to develop potential regulatory and incentive mechanisms to accelerate deployment of IMO Tier 3 marine vessels to U.S. ports. (2) Key tasks would be…
Scope: Background concentrations representative of a project area are the most critical information needed for transportation projects subject to the new guidance for quantitative hot-spot analyses of particulate matter (PM). The…
Scope: Transitioning to use of cleaner energy in transportation has the potential to address multiple needs including energy security, energy cost certainty, local air quality, and climate. Many of these benefits…
Scope: The AASHTO Air Quality Community of Practice May 2012 draft report “Establishing and Coordinating Motor Vehicle Emissions Budgets State-of-the-Practice” recommended an NCHRP study to: “advance the state-of-the-practice for establishing…
Effective December 20, 2012, a new era in air quality analyses for transportation projects began as federal transportation conformity rule requirements and associated guidance issued by the US EPA for…
Successful research efforts require identifying all of the conditions and unknowns surrounding the area of interest and then defining them. This requires developing a plan for conducting research which identifies…
Background: Construction activities can produce fugitive dust and exhaust emissions of criteria pollutants from heavy duty construction equipment. The AASHTO Air Quality Community of Practice issued State of the Practice…
The proposed study would develop a practical guide for (or compendium of) mitigation measures for air quality for typical highway and transit projects that, ultimately, may serve as the basis…
In 2012, the EPA MOVES model became a requirement for air emissions modeling on transportation projects. In addition to MOVES, EPA regulations require dispersion modeling using one of two allowable…
November 2012 Proposal: Effective December 20, 2012, a new era in air quality analyses for transportation projects begins as regulatory requirements issued by the US Environmental Protection Agency (US EPA)…
