There is little point, of course, in getting the acid out of the lower North Branch unless the other pollution in that area is dealt with too. This compounded trouble, involving a considerable number of towns and industries with insufficient waste treatment or none at all, is made to order for a pilot application of the regional or sub-basin type of waste management authority mentioned earlier in this chapter. Not only is the problem on the North Branch bad enough to warrant special overall measures, but the area's topography is well suited to collection of wastes and their conveyance to first-rate centralized treatment plants. This approach too is being studied out by INCOPOT, not only for the North Branch but for other well-adapted problem watersheds such as Antietam Creek. Like similar systems in Germany that have long been admired, it would pool the resources of all sub-basin waste producers, get appropriate government funding, and subject all the pollution of a given drainage area to intensive and comprehensive correction. Machinery Though its spread-out economic benefits are almost incalculably great, good waste management unfortunately is seldom a money-making affair for those who sponsor it. Therefore, it is not usually so much the concern of private enterprise as of citizens in general and the various levels of government that look after the citizens' desires and wellbeing. It depends on laws to back it up, and on institutions and programs established by law. These are the only machinery by which it can be adequately stimulated, unless we assume that all waste producers are altruistic to a point of self-sacrifice, an assumption which history does not encourage. Thanks to thoroughly justified public anxiety over the state of American waters, there is presently on hand the best assortment of such legal machinery that has ever existed, much of it so new as to be mainly untested. The Key Federal item is the Water Quality Act of 1965, which established the Federal Water Pollution Control Administration and set into motion a national program to clean up interstate and tidal waters. In the program the States were allotted primary responsibility for setting standards of cleanliness and were given until June 30, 1967, to work them out and submit them to the Federal Water Pollution Control Administration for review. Later came the Clean Waters Restoration Act of 1966, which authorized funds for F.W.P.C.A. construction grants to help communities build waste treatment facilities. Programs under other government agencies are also aimed at helping towns and cities deal with wastes.
