Air Quality Conformity

HRBT Tunnel CongestionIn accordance with Federal regulation 23 CFR 450.326, “in nonattainment and maintenance areas subject to transportation conformity requirements, the FHWA and the FTA, as well as the MPO, must make a conformity determination on any updated or amended TIP, in accordance with the Clean Air Act requirements and the EPA’s transportation conformity regulations (40 CFR part 93, subpart A).”

The Hampton Roads MPA has been designated an attainment area for all current National Ambient Air Quality Standards. Therefore, the air quality conformity requirements do not currently apply to the HRTPO TIP.
