"Rebuttable presumption" presumes protection and propagation of fish, shellfish, and wildlife and recreation in and on the water are attainable, unless otherwise demonstrated consistent with 131.10(g).

• By implementing cost-effective and reasonable best management practices for non-point source control.
• Performance standards for particular industrial sources.
