Under Work Assignment No. 2-03 of Contract No. 68-C4-0056, Sierra Research, Inc. (Sierra) has assisted EPA in responding to the National Highway System Designation Act by developing a proposed protocol for the evaluation of state I/M programs in areas subject to the enhanced I/M requirements of the Clean Air Act Amendments of 1990. The objective of the proposed evaluation process is to determine whether state I/M programs are as effective as a benchmark program that meets the requirements of the Clean Air Act for enhanced I/M. After considering a variety of potential approaches, Sierra has concluded that the most practical method for estimating the effectiveness of various I/M programs will be to compare the emissions and evaporative system test results of vehicles that have gone through alternative programs to the emissions and evaporative system test results of vehicles subject to the benchmark program.
