This Programmatic Agreement (PA) between the Virginia Department of Transportation (VDOT) and the Virginia Division of the Federal Highway Administration (FHWA Virginia Division) specifies terms for screening highway projects for potential carbon monoxide (CO) impacts that are currently undergoing environmental studies to meet requirements of the National Environmental Policy Act (NEPA). This PA establishes the types of projects and project conditions that will not require project-specific modeling or a quantitative air quality analysis to document that they do not cause a violation of the National Ambient Air Quality Standards (NAAQS) for CO. Rather, these project types and conditions will require only a general qualitative statement to meet project-level air quality requirements that references this agreement and the associated technical support document (TSD), which presents worst-case modeling results for CO that would cover the specific project type and condition.
