Water Quality Standards Regulation (Non-Substantive Change)

The Water Quality Standards (WQS) regulation at 40 CFR part 131 establishes the framework for states and authorized tribes to adopt WQS for waters of the United States, and for the EPA to review and approve or disapprove the WQS. This ICR is for information collections needed to implement the WQS regulation, required to obtain or retain benefits (e.g., relaxed regulatory requirements) under the WQS regulation, and to collect voluntary program information useful in administering WQS programs effectively and efficiently. This ICR renewal describes the estimated information collection burden for states, authorized tribes, tribes seeking authorization, and certain Great Lakes dischargers to: adopt, review, and revise WQS; comply with specific requirements of the regulation; submit tribal applications to be treated in a similar manner as a state (TAS); request regulatory relief; request certain EPA dispute resolution assistance; and provide voluntary WQS program information.
