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.
