This testimony before the Subcommittee on Environment and the Atmosphere concerns the issue of sulfur oxides. A chronology was presented of the activities in this area dating from the mid nineteenth century and projecting through 1977. Three particular types of problems were addressed: policy problems, organizational problems and resource problems. Control of sulfur oxides was considered important for the protection of public health, the attainment of national energy self sufficiency, the pursuit of economic growth with equitable economic opportunity, and the enhancement of environmental quality. Unless there is a clear delineation of the relationship between research programs to national policy, it is not likely that research scientists can go about the business of getting the information needed to give the best solution to long range national problems. The major environmental issues have time frames that are much longer than the tenure of key decision makers or the longevity of organizations established to deal with these problems. It is vital that Federal regulation of environmental and occupational issues be based on solid scientific evidence. Several recommendations were offered to allow the efforts of the regulatory and scientific agencies to advance toward their common goals more smoothly.
