State On-Road Mobile Source Emissions Reductions Report - Utah
The information below summarizes the TPM On-Road Mobile Source Emissions Reductions performance measure. Per 23 CFR 490, State Departments of Transportation (DOTs) are required to establish 2- and 4-year targets for this measure. The targets should represent the anticipated condition/performance at the mid-point and end of the 4-year performance period. State DOTs establish targets at the beginning of each 4-year performance period, and report on progress every two years. When establishing targets, State DOTs have the flexibility to use the methodology they deem most appropriate. FHWA encourages States to review data sets and trends and consider factors that may affect targets. Performance targets should be data-driven, realistic, and attainable and should align with the performance management framework and legislative intent.
The targets and discussion of basis for targets, optional adjustment of targets, progress, and planned activities were provided by the State DOT in its most recent biennial performance report. FHWA has not edited this information. It is provided to help bring context to the State DOT’s performance targets and progress. Any questions about the information should be directed to the State DOT.
Data reported by State DOTs was collected in the previous year, representing the condition/performance at the time of collection. Thus, in the tables and graphs below, FHWA labels data with the year representing the condition/performance, rather than the year the data was reported. The same thing is done for the targets--the year represents when the corresponding actual condition/performance data will be collected, not reported. More Information.
Total Emission Reduction Measure is the 2-year and 4-year cumulative estimated emission reductions, for all CMAQ funded projects, of each applicable criteria pollutant (ozone (O3), carbon monoxide (CO), and particulate matter (PM2.5 and PM10)) and precursor (volatile organic compounds (VOC) and oxides of nitrogen (NOx)) for which the area is designated nonattainment or maintenance (23 CFR 490.807). See the example below:
- The 2021 baseline presents the cumulative 4-year emissions reductions in the baseline period from Fiscal Year (FY) 2018 through FY2021 as provided by the state DOT in the Baseline Performance Period Report.
- The 2023 actual presents the cumulative 2-year emissions reductions from FY2022-FY2023 as provided in the CMAQ Public Access System.
- The 2023 target presents the state-selected target of expected cumulative 2-year emissions reductions from the midperiod performance period FY2022-FY2023
- The 2025 actual presents the cumulative 4-year emissions reductions from FY2022-FY2025 as provided in the CMAQ Public Access System
- The 2025 target presents the state-selected target of expected cumulative 4-year emissions reductions from the full performance period FY2022-FY025.
The CMAQ Public Access System (PAS) and associated annual CMAQ project reporting process make available searchable CMAQ project information from 1992 to present. These data were used for other, non-performance management purposes during the fiscal years before FY 2018. In 2015, FHWA made changes to the CMAQ database to accommodate legislative amendments to title 23, U.S.C. (see 23 U.S.C. 149(i)(1)), and to improve functionality. State-level baseline emissions reductions calculations for FY 2014-2017 may vary from PAS-reported values for a number of reasons, such as change in nonattainment/maintenance area status within the baseline period, individual project data entry errors, and other state-level modifications. Future performance calculations are expected to have increased consistency with the application of PAS data for performance management beginning in FY2018.

MAG and WFRC identified the emissions reductions for projects within the period as reported to the CMAQ Public Access System. Due to some errors in that system that have not been corrected (though correction was attempted by WFRC), WFRC adjusted those values by determining the average reductions from 2020 and 2021 and set the target for the second performance period.-
