Key Point. EPA does not review or act on elements of a State/Tribe's submission that are not subject to the CWA (e.g., groundwater criteria).

EPA must complete its review and approve or disapprove the State/Tribe's submission within specified time frames, which differ depending on the determination. Select the links below to view the time frames:

Approve:

If EPA decides that the submission meets the CWA requirements, the Agency has 60 days from the submission date to issue a letter approving the submission (40 CFR 131.21(a)(1)). At that point, the standards become applicable.Thumbs Up Icon

Disapprove:

If EPA decides that the submission does not comply with the CWA requirements, the Agency has 90 days from the submission date to issue a letter disapproving the submission and specifying changes that should be made to bring the standards into compliance (40 CFR 131.21(a)(2)).Thumbs Down Icon
