A bill to amend the Federal Water Pollution Control Act relating to the adoption of a system of charges for waste treatment services.

Amends the Federal Water Pollution Control Act to authorize the Administrator of the Environmental Protection Agency to approve user charge systems based upon ad valorem taxation if such systems (1) result in an equitable distribution of operation and maintenance costs to user classes in proportion to the contribution of each such class to the loading of the treatment works, and (2) insure that industrial users will pay a proportionate share of the costs through a system of surcharges.
