Transportation Conformity

Clean Air Act regulations require that federally-funded transportation projects and private development projects needing federal approvals "conform" to mandated emission reductions under State Implementation Plans. This often-overlooked requirement is critical for many projects and has spawned litigation by special-interest and NIMBY groups that oppose highway infrastructure and development projects. Beveridge & Diamond, P.C. has successfully represented companies, trade associations, and governmental entities in difficult cases of first impression that threatened to stop or delay the construction of roads, interchanges and other transportation improvements or development because of alleged failures to satisfy these requirements.
