As part of monitoring and assessing water quality status, every 2 years States/Tribes must submit "integrated reports" to EPA that include the following:

• Assessment methodology for WQS attainment decisions.
• Categorization of all State/Tribal waters based on WQS attainment status.
• Results of probability-based design at State/Tribal or watershed scale.
• Monitoring priorities for the next 2 years.
• Total Maximum Daily Loads (TMDL) development priorities for all Category 5 waters (i.e., waters impaired or threatened by a pollutant or pollutants).

Resource. For more information on the requirements for submission of biennial “integrated reports” on water quality status, see EPA’s webpage on this topic
