# Indian Tribal Approvals

The following chart lists EPA approvals for tribes to administer a water quality standards (WQS) program, and EPA’s approvals of those tribes’ WQS. A tribe may administer a WQS program if it applies and EPA finds that it qualifies under Section 518(e) of the Clean Water Act to be treated in a manner similar to a state (“TAS”). Currently, 49tribes have been found eligible to administer a WQS program, and EPA has approved at least initial WQS for 40of these tribes. EPA has promulgated federal WQS for 1 tribe not included in these totals.
