Document:
(a) Purpose. The purpose of this section is to implement certain requirements set forth in 40 Code of Federal Regulations (CFR) Part 93, Subpart A (relating to Conformity to State or Federal Implementation Plans of Transportation Plans, Programs, and Projects Developed, Funded, or Approved Under Title 23 United States Code (USC) or the Federal Transit Laws), which are the regulations developed by the United States Environmental Protection Agency (EPA) under the Federal Clean Air Act Amendments of 1990, §176(c)(4)(e). This section addresses the consultation process and the written commitment requirements for control measures and mitigation measures that are used to demonstrate and assure conformity of transportation planning activities with the state implementation plan (SIP).
(b) Applicability. This section applies to transportation-related criteria pollutants for which an area is designated nonattainment or is subject to a maintenance plan. The transportation-related criteria pollutants are ozone, carbon monoxide, nitrogen dioxide, particles with an aerodynamic diameter of ten micrometers (PM 10 ) and smaller, and particles with an aerodynamic diameter less than or equal to a nominal 2.5 micrometers (PM 2.5 ). This section also applies to the precursors of ozone, nitrogen dioxide, PM10 , and PM2.5 as required in 40 CFR §93.102.
(c) CFR incorporation. The written commitment requirements as specified in 40 CFR §93.122(a)(4)(ii) and §93.125(c) are adopted by reference.
(d) Consultation. Under 40 CFR §93.105, regarding consultation, the following procedures must be undertaken in nonattainment and maintenance areas before making conformity determinations and before adopting applicable SIP revisions.
(viii) local air quality agencies in nonattainment or maintenance areas (recipients of 42 USC, §7405 funds).
(xi) commission regions in nonattainment or maintenance areas: regional director or designee.
(2) Roles and responsibilities of affected agencies.
(xi) for the purpose of determining the conformity of all projects outside the metropolitan planning area, but within the nonattainment or maintenance area, enter into an MOA involving the MPO and TxDOT for cooperative planning and analysis of projects.
(v) consult with the applicable agencies specified in paragraph (1)(A) of this subsection, in order to cooperatively choose conformity tests and methodologies for isolated rural nonattainment and maintenance areas, as required by 40 CFR §93.109(l)(2)(iii).
(C) Any group, entity, or individual planning to construct a regionally significant transportation project that is not an FHWA-FTA project (including projects for which alternative locations, design concept and scope, or the no-build option are still being considered) shall disclose project plans to the MPO on a regular basis and disclose any changes to those plans immediately. This requirement also applies to recipients of funds designated under 23 USC or the federal transit laws.
