The Federal Transit Administration (FTA) is seeking public feedback on updated CIG Policy Guidance for transit grant projects. The agency has requested feedback on these new standards to continue the process of updating CIG Policy Guidance, which provides direction to project sponsors pursuing CIG construction grants. Following feedback from transit industry partners, FTA is proposing to remove the social cost of carbon calculation from the Environmental Benefits section of the CIG Policy Guidance. FTA published a proposed interim guidance update for public comment. Federal law requires FTA to update CIG Policy Guidance at least every two years.
