Water quality standards are to be established for and made applicable to all interstate and intrastate waters under the provisions of the Water Pollution Control Act Amendments of 1972 (FWPCAA). The Act contains different time schedules for establishment and approval of intrastate standards depending upon whether or not a State now has such standards. After adoption by the State and approval by EPA, standards will apply to all navigable waters; the terms interstate and intrastate will have no significance. The objective of the Federal Water Pollution Control Act Amendments of 1972 is to restore and maintain the chemical, physical, and biological integrity of the Nation's waters.
