State On-Road Mobile Source Emissions Reductions Report - Illinois

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 2017 baseline presents the cumulative 4-year emissions reductions in the baseline 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 actual presents the cumulative 4-year emissions reductions from FY2018-FY2021 as provided in the CMAQ Public Access System.
The 2021 target presents the state-selected target of expected cumulative 4-year emissions reductions from the full performance period FY2018-FY021.

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.

Basis for Emissions Reductions for PM_2.5 through CMAQ Projects
The Chicago Metropolitan Agency for Planning - The combined the total daily emissions for The Chicago Metropolitan Agency for Planning’s FFY 2018-2022 CMAQ program was used to develop an annual estimate to generate the 2-year and 4-year targets. East-West Gateway Council of Government- To inform the 2-year and 4-year targets, East-West Gateway Council of Government used emissions totals from the actual projects scheduled for the given time periods. Because E/W Gateway does not have projects programed in the out years FFY20 and FFY21 their numbers are the same for their 2-year and 4-year targets. East West Gateway provides a breakdown of anticipated projects that result in Illinois' total emission reduction on pages 11 and 12 of the PDF (pages #9 and 10 of the document) of their CMAQ performance plan. For East West Gateway, the baseline for IL was determined based on the entries into the CMAQ Public Access System for IL. Table 5 in the East West Gateway CMAQ performance plan shows the breakdown between Missouri and Illinois baseline emission information for East West Gateway. More information is available in each MPO's Performance Plan.

In 2018 when first reporting the CMAQ Performance Measures for emissions the State of Illinois was in nonattainment for the critical pollutant PM2.5. Since 2018 the U.S. Environmental Protection Agency has designated Illinois as attaining the emissions standards for the pollutant PM 2.5. Based on this new designation and our understanding of the performance measure qualifications we do not believe further reporting on this pollutant is necessary.

During this performance period FHWA did not have a vehicle Buy America Wavier process in place. Because of this a significant number of diesel retrofit projects were selected at the MPO level, agreements drafted with the state DOT, but never implemented because of this lack of policy. Despite this, both MPO regions tried their best allocating CMAQ projects to reduce PM 2.5 emissions.

Lyons Township in western Cook County is designated a maintenance area for the 1987 standard for PM10. This is a point source problem related to quarry activities within the township. Because the emissions are unrelated to transportation and mobile sources, CMAP has recommended the targets to be set at zero.

Due to the lack of administrative guidance and approval of Buy America Waivers over the past 3+ years many emission reduction projects have not been able to proceed. This played a major role in the difference in numbers. Chicago- The progress assessment for the emissions reduction shows that both the 2-year targets for NOx and PM2.5 have been meet as well as the 4-year year targets for those criteria pollutants. The VOC assessment shows a 16.892 kilograms per day short fall which is 14% of the 2-year target. Looking at the description of projects in Table 7 of the CMAP Performance Plan (attached) shows that 5 out of the 9 project types underperformed based upon the program of projects in 2018. Those projects that did not move to construction or implementation are still in the program and the region is still able to meet the VOC 4-year target. No adjustment to the 4-year target is recommended at this time. E/W Gateway- The reported benefits in the CMAQ Public Access system are lower by 61.4 kg than the two-year target set in 2018 due to CMAQ projects that did not move forward in the 2018-2019 timeframe. These projects are still included in the four-year target.

E/W Gateway - The four-year target is being adjusted to account for CMAQ projects that have been programmed since the baseline report. It also includes projects that were not delivered in the first two years (2018-2019). Chicago- No Change

A number of projects in both MPO regions did not move forward due to the COVID-19 pandemic leading to a large unobligated balance during this reporting period. Also, it is FHWA policy that emissions numbers be added in the CMAQ Reporting system when there is a first obligation for the project rather than when a project completes construction. This discrepancy allows for front loading of emissions numbers for projects that have not yet been completed.
