State On-Road Mobile Source Emissions Reductions Report - Georgia

In the line graphs below, FHWA has shifted the "Year" label in the x-axis back by one year, from Data Reporting Year to Data Collection Year. More information

The information displayed is provided by the State Department of Transportation (DOT) in their 2018 Baseline Performance Report, and 2020 Mid Performance Period (MPP) Progress Report and has not been edited by FHWA. Any questions about individual State reports should be directed to the respective State DOT.

Please note: FHWA has posted data from State DOT reports to help bring context to their performance targets. This data may result in some discrepancies among published State DOT performance data due to data sources and reporting years used when establishing the performance targets.

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.

  • The 2017 baseline presents the cumulative 4-year emissions reductions in the bassline period from Fiscal Year (FY) 2014 through FY2017 as provided by the state DOT in the Baseline Performance Period Report.
  • The 2019 actual presents the cumulative 2-year emissions reductions from FY2018-FY2019 as provided in the CMAQ Public Access System.
  • The 2019 target presents the state-selected target of expected cumulative 2-year emissions reductions from the midperiod performance period FY2018-FY2019.
  • The 2021 target presents the state-selected target of expected cumulative 4-year emissions reductions from the full performance period FY2018-FY2021.

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 FY2018. In 2015, FHWA made changes to the CMAQ database to accommodate legislative amendments to Title 23 (see 23 USC 149(i)(1)) and improve functionality. State-level baseline emissions reductions calculations for FY14-17 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.

    A detailed report was prepared by Georgia Department of Transportation (GDOT) that provides an overview of the “National Performance Management Measures for Assessing Performance of the National Highway System, Freight Movement on the Interstate System, and Congestion Mitigation and Air Quality Improvement Program (CMAQ) Final Rule”, the methodology to calculate the measures included in the rule, target setting process as well as the recommended 2 and 4-year performance targets.

    Using the FHWA CMAQ Public Access Database, the 2-year condition was compared to the 2-year target. An upward trend indicates increased reductions in emissions, and as indicated by the 2-year condition 631.900 kg/day being higher than the 2-year target at 563.300 kg/day, the indication is that emissions reductions are greater than anticipated.

    More information can be found in the detailed report that was prepared by Georgia DOT that provides an overview of the “GDOT 2020 Mid Performance Period Progress Report MAP-21 and Fast Act PM3 Rule”, the comparison of the 2-year condition to the baseline condition and 2-year target, discussion on the reasons for differences in the actual and target values, 4-year target evaluation, and 2-year and 4-year significant progress for NHPP targets.
