An analysis is given of the macroeconomic impacts of federal air and water pollution control legislation on the U.S. economy. The analysis relies upon CEQ incremental abatement cost estimates. Figures were provided for capital investment, annualized capital costs, and operating and maintenance costs on an industry-by-industry basis, with additional data for state and local governments costs and costs associated with mobile source regulations. The figures reflect on incremental costs, i.e., the extra costs which occurred solely as the result of federal legislation. As such, they do not reflect some pollution control outlays which would have been undertaken even in the absence of the legislation.
