On-road remote sensing tests shall be scheduled to occur at least once a year by the Agency or its designee in each affected county, distributed throughout the inspection areas in proportion to the number of subject vehicles registered in these areas, and performed in accordance with the procedures specified in subsections (b) through (e) of this Section.
The on-road remote sensing test shall consist of measuring the concentration of HC, CO, and CO2, and automatically recording the speed, acceleration, and license plate of each in-use vehicle. Compliance is determined by comparing the measured emission concentration of each pollutant to the on-road remote sensing emission standards contained in 35 Ill. Adm. Code 240.182.
Test locations for on-road remote sensing tests shall be sited such that:
The owner of any non-exempt vehicle that has previously been through an in-cycle emissions test and passed the final retest, or is determined to be out of compliance, which is found with an exceedence of the on-road remote sensing emission standards, shall be notified of such exceedence. If a second exceedence occurs prior to the next scheduled in-cycle emissions test, the Agency will reassign the vehicle and notify the owner of a required out-of-cycle exhaust emissions test.
