EPA-Established Final TMDLs

Although most TMDLs are adopted by states, territories, or authorized tribes, and then approved by EPA, EPA also establishes TMDLs in some cases if:

• EPA disapproves TMDLs submitted by states, territories, or authorized tribes,
• States, territories, or authorized tribes do not submit TMDLs in a timely manner,
• EPA is required to do so pursuant to litigation settlements or judicial orders, or
• States ask EPA to establish TMDLs for particular water bodies.

The following are TMDLs which have been completed by EPA as part of legal requirements under lawsuit settlement consent decrees. EPA-established TMDLs covering other bodies of water will be added as they become available.

San Diego Creek, Newport Bay Sediment TMDL

EPA established TMDLs for sediment, nitrogen, and phosphorus for Newport Bay and San Diego Creek, CA on April 13, 1998. EPA subsequently approved slightly revised TMDLs submitted by the State of California for sediment, nitrogen, and phosphorus for Newport Bay and San Diego Creek on April 16, 1999. These State-adopted TMDLs supercede the TMDLs previously established by EPA.
