Small Watershed Projects Boost Economy of Communities
This being so, the good of the Basin and the Potomac as a whole is going to require the exercise of State and interstate and Federal power against silt as well as against other pollution, especially around populated areas, until such time as the populated areas have developed the political maturity to take firm hold of their responsibilities in such matters. Laws and ordinances of themselves solve nothing. For example, many of the pollutive dribbles along Rock Creek and other metropolitan watercourses are based in clearly illegal practices and hence slovenly inspection and enforcement of existing regulations. Others occur because of defects in the sewer system that could and should be found and repaired. A shortage of manpower is one reason for such trouble, but poor philosophy is a bigger one.
States, interstate bodies, and municipalities, however, can exert no control over another and rather shameful set of pollution sources noted earlier in this chapter. These are the delinquent Federal installations in the Basin, generally but not always in the neighborhood of the capital, that are contributing to the river's problem. Recent publicity, much of it deriving from aspects of this present study, has been bringing about some improvement, as has President Johnson's Executive Order 11288, which directed that Federal facilities set the best example in the matter of pollution control. But the order has obviously not been obeyed with uniform enthusiasm in all quarters, defective philosophy and short waste-disposal budgets being no exclusive property of local governments. Sometimes this is because limited funds force agencies to put waste treatment far down on their list for spending, and little is left over for it. Whatever the reason in individual cases, a continuation of persuasion and enforcement by the F.W.P.C.A. within the Federal establishment is going to be essential, and Federal installations ought to be required at least to equal or excel the quality of treatment provided by other waste producers on the same streams or bodies of water. Furthermore, all the diverse pollutive activities dependent on Federal aid and cost-sharing—such as road construction, for instance—ought to be brought under similar controls.
Certain major changes in public policy are needed if different techniques of water quality improvement are to be combined in such a way as to give the most economical, appropriate, and effective protection to specific streams or river systems. The most important of these needed changes concerns the role of flow augmentation as a tool, for inclusion of water quality storage capacity in Federal reservoirs is a fairly new and uncertain practice, and some rather deep pitfalls are becoming evident.
One pitfall has to do with Federal Cost-sharing and the way it affects the freedom of choice of the States and localities on which the primary responsibility for eliminating pollution must rest. In building treatment plants to lessen the load of wastes discharged to streams, they can presently obtain Federal grants of up to 55% of the facilities' total cost. But if storage capacity for water quality—i.e., for flow augmentation—is provided in a Federal reservoir upstream, prevailing Federal policy based in a 1961 amendment to the Federal Water Pollution Control Act has been requiring them to pay nothing at all for it, though before such storage is authorized they must certify that an adequate standard of conventional treatment will be maintained downstream. Obviously, if this continues to be so, when the inevitable choice comes between improving on that adequate standard by investing in better treatment, either at the beginning or later, and seeking river dilution from a reservoir, they will be forced by sheer economics toward the latter, whether or not it is the right thing to do or in an overall sense the cheapest.
Like other aspects of flow augmentation already discussed, this situation is analogous to that of flood control, where communities have to pay a good part of the cost of local protection works or of controlling flood plain development, but can get reservoir protection free. In both cases, local authorities are stimulated toward choices that are not necessarily the right ones, taxpayers in general are forced to bear the weight of essentially local responsibilities, and the public may forever lose scenic or recreational amenities of great worth. The Department of the Interior, with a central interest in the problem, is taking the lead in an attempt to arrive at a better flow-augmentation policy that will permit right choices, put costs where they belong, and make certain that at the local level where pollution takes place there is sharp incentive to do something about it.
The other main difficulty has to do with the fact that river water has many uses, which augmentation may enhance or even stimulate. Water released from above during dry periods to increase and steady the river's flow and to help it handle wastes may also help navigation and hydroelectric power generation downstream, though neither of these is any longer a main factor in the flowing Potomac. Augmentation of flow can make the river prettier and more useful for recreation, and it can have stout beneficial effects on fish and wildlife. And under present conditions it constitutes a large increase in water of improved quality for free use by irrigators and industries and municipalities, which may so burgeon as a result that increased water consumption and waste production will cancel out the water quality effects of the reservoir releases in short order.
The need here, of course, is for some agency that can solidly guarantee that water released for quality control will be allowed to achieve that purpose and not be diverted to other uses that conflict with it. Where a river runs within a single State, and the State's constitution permits, the State may be able to adjust its powers of control and provide the guarantee. But where more than one State is involved, as on all the main rivers of the Potomac Basin, a good forceful river basin agency is clearly needed to coordinate water supply with water demand, and to ensure that benefits and cost responsibilities of any necessary reservoirs are meted out where they belong.
In terms of legal and institutional machinery, in fact, such a river basin agency is the most basic and urgent unfulfilled need along the Potomac, for the coordination and continuing supervision of water management in all its phases—assurance of supply, flood protection, quality improvement, recreation—in the vast physical unit of land drained by the river. And because land's condition is so often influential on the quality and utility of water, the agency's concern and authority must encompass some fundamental matters of land use as well.
