A sample of 300 of the 1964 through 1973 model-year vehicles was utilized to investigate the effectiveness and feasibility of several exhaust emission control strategies as might be applied in the Colorado environment. Four strategies were evaluated; idle emissions inspection in the private sector, exhaust control retrofit, modified engine tuning specifications and mandatory engine maintenance. Each of the strategies is discussed for effectiveness in reducing exhaust hydrocarbon, carbon monoxide, and oxides of nitrogen emissions.
