Notice of Ambient Aquatic Life Water Quality Criteria for Tributyltin (TBT)-Draft

Riepilogo

Section 304(a)(1) of the Clean Water Act (CWA) requires the Environmental Protection Agency (EPA) to develop, and publish and, from time to time, revise criteria for water that accurately reflect the latest scientific knowledge. These criteria represent EPA's current recommendations to States, Territories, and authorized Tribes to use as technical information in establishing their water quality standards as state or tribal law or regulation. Such standards may form the basis for establishing water qualty-based controls. These water quality criteria are not regulations and do not impose legally-binding requirements on EPA, States, Territories, Tribes or the public. Today, EPA is announcing the availability of draft water quality criteria for tributyltin (TBT) for scientific and technical input. EPA is notifying the public about the request for scientific and technical input on the draft criteria for TBT in accordance with the Agency's process for developing or revising criteria (63 FR 68354, December 10, 1998).
