(viii) If the metropolitan planning area boundary, in paragraph (f)(6)(i) of this section, does not contain any part of a nonattainment or maintenance area for the applicable criteria pollutants, as specified in § 490.803, 1 year before the State DOT Mid Performance Period Progress Report is due to FHWA, as described in paragraph (f)(6)(v) of this section, then that MPO is not required to meet the requirements in § 490.107 for the Total Emissions Reduction measure for that applicable criteria pollutant or precursor for the remainder of that performance period.

(7) MPO response to State DOT target adjustment. For the established targets in paragraph (f)(3) of this section, if the State DOT adjusts a 4-year target in the State DOT's Mid Performance Period Progress Report and if, for that respective target, the MPO established a target by supporting the State DOT target as allowed under paragraph (f)(3)(i) of this section, then the MPO shall, within 180 days, report to the State DOT whether it will either:

(i) Agree to plan a program of projects so that they contribute to the adjusted State DOT target for that performance measure; or

(ii) Commit to a new quantifiable target for that performance measure for its metropolitan planning area.

(8) Target adjustment. If the MPO establishes its target by committing to a quantifiable target, described in paragraph (f)(3)(ii) of this section or establishes target(s) for the Total Emissions Reduction measure required in paragraph (f)(6)(iii) of this section, then the MPOs may adjust its target(s) in a manner that is collectively developed, documented, and mutually agreed upon by the State DOT and MPO. Any adjustments made to 4-year targets, established for CMAQ Traffic Congestion measures in paragraph (f)(5)(i) or (ii) of this section, shall be collectively developed and agreed upon by all State DOTs and MPOs that include any portion of the NHS in the respective urbanized area applicable to the measure.

(9) Reporting. The MPOs shall report targets and progress toward the achievement of their targets as specified in § 490.107(c). After the MPOs establish or adjust their targets, the relevant State DOT(s) must be able to provide these targets to FHWA upon request.

(10) Joint Targets for the GHG Measure. Where an urbanized area contains mainline highways on the NHS, and any portion of that urbanized area is overlapped by the metropolitan planning area boundaries of two or more MPOs, those MPOs shall collectively establish a single joint 4-year target for that urbanized area, described in paragraph (e)(4)(iv) of this section. The target established shall be a declining target for reducing tailpipe CO2 emissions on the NHS. This joint target is in addition to the targets for the metropolitan planning area required in paragraph (f)(1)(i) of this section.

(i) The NHS designations and urbanized area data shall be from the data contained in HPMS 1 year before the State DOT Baseline Performance Period Report is due to FHWA.

(ii) Only one target shall be established for the entirety of each applicable urbanized area regardless of roadway ownership. In accordance with paragraph (f)(9) of this section, each MPO shall report the same joint target for the urbanized area.

(iii) The target established for each urbanized area shall represent a quantifiable target for that urbanized area.
