				  enjoyment of the water for any lawful or reasonable purpose.

				  quality-based process used to establish pollution control limits for waters not

				  not adequate and should include determination of loading capacity, allocations
				  of wasteload and loading from other pollutant sources, and an appropriate
				  margin of safety.
(9) Unclassified
