The Clean Air Act Amendments of 1977 mandate the U.S. Environmental Protection Agency to further control emissions from light-duty trucks and heavy-duty engines. This technical report uses published vehicle scrappage and mileage accumulation data to estimate average lifetime periods for light-duty trucks and heavy-duty engines. These lifetime periods can be used in the air quality, economic impact, and cost effectiveness analyses associated with the pending and upcoming rulemaking actions affecting light-duty and heavy-duty engines.
