Abstract

EPA has recently evaluated several automobile retrofit devices that are potentially applicable to pre-1975 vehicles. The results of this evaluation are described and used to estimate the effectiveness and cost of retrofit for reducing total automobile emissions in the period 1975-1985. It is estimated that retrofit combined with inspection/maintenance can potentially achieve reductions in automobile emissions of 33% to 60% in 1975, depending on pollutant, and 10% to 20% in 1985. The estimated present value discounted to 1972 of the average cost per retrofit vehicle is $30 to $152 over the period 1975-1985 depending on the retrofit system used. The corresponding annualized cost is $6 to $28 per vehicle.
