lication of measures to control them. (f) Acceleration of research to find methods of treating industrial wastes for which suitable methods presently are not available. (g) Evaluation of major point sources of mine drainage in the upstream watersheds of the North Branch of the Potomac River and development of mine drainage abatement measures and control programs which are technically and economically feasible. (2) Concurrently--and at the earliest possible date--must come application of knowledge obtained through research, demonstration projects and field investigations performed within the Potomac Basin and elsewhere. As possible, water quality standards should be upgraded to reflect this new knowledge. Application of findings should include: (a) The progressive practical application of advanced waste treatment and improved methods of treatment or control of combined and storm sewer discharges in metropolitan Washington and elsewhere. (b) Application of additional measures necessary for controlling estuarial pollution still present after maximum feasible waste treatment, including advanced waste treatment, has been provided in the area. (c) Continuing reassessment of the effect of reservoir releases on water quality in the flowing streams of the Basin, after the highest practicable degree of waste treatment has been provided. Such assessment will involve: (1) Reevaluation of the opportunities for obtaining improved water quality objectives through management of reservoir releases and stream flows as individual reservoir projects are considered for construction, in the light of advanced waste treatment, means of coping with agricultural runoff and drainage, and other alternatives made available by that time. (2) Development of the Federal water resources policies which will provide for the most effective application of the streamflow regulation provisions of the Federal Water Pollution Control Act, including equitable cost-sharing arrangements, to assure that streamflow regulation assumes its proper role in relation to other pollution control alternatives for the Basin.
