§ 93.116 Criteria and procedures: Localized CO, PM10, and PM2.5 violations (hot-spots).

(a) This paragraph applies at all times. The FHWA/FTA project must not cause or contribute to any new localized CO, PM₁₀, and/or PM_2.5 violations, increase the frequency or severity of any existing CO, PM₁₀, and/or PM_2.5 violations, or delay timely attainment of any NAAQS or any required interim emission reductions or other milestones in CO, PM₁₀, and PM_2.5 nonattainment and maintenance areas. This criterion is satisfied without a hot-spot analysis in PM₁₀ and PM_2.5 nonattainment and maintenance areas for FHWA/FTA projects that are not identified in § 93.123(b)(1). This criterion is satisfied for all other FHWA/FTA projects in CO, PM₁₀ and PM_2.5 nonattainment and maintenance areas if it is demonstrated that during the time frame of the transportation plan no new local violations will be created and the severity or number of existing violations will not be increased as a result of the project, and the project has been included in a regional emissions analysis that meets applicable §§ 93.118 and/or 93.119 requirements. The demonstration must be performed according to the consultation requirements of § 93.105(c)(1)(i) and the methodology requirements of § 93.123.
