Current Status of the Texas Integrated Report (IR) for Clean Water Act Sections 305(b) and 303(d) Water Quality Planning Division Monitoring & Assessment Section Surface Water Quality Monitoring Program (SWQM)

Background Statewide assessment of the status of state waters Compares water quality data to approved water quality standards Identifies impaired waters (303(d) List) Requirements Federal Clean Water Act, Sections 305(b) and 303(d) Title 30 of the Texas Administrative Code (30 TAC) Conducted every two years Draft due to EPA on April 1 of even numbered years The Integrated Report represents a statewide assessment of the status of state waters and compares water quality data to approved water quality standards. This allows us to identifies water not meeting water quality standards as impaired and these are included on what is known as the 303(d) List. The requirements for this assessment are included in the Federal Clean Water Act, Sections 305(b) and 303(d) as well as Title 30 of the Texas Administrative Code (30 TAC). This assessment is conducted every two years and the draft due to EPA on April first of even numbered years.

Integrated Report (IR) - Process Develop Guidance Assemble\Compile Data Update Assessment Tools Develop Draft Reports Solicit Public Comment Revise Draft Documents TCEQ Approval EPA Approval – IR considered draft until approved by EPA The process for developing the Integrated Report includes the following steps, develop guidance, assemble and compile data, update electronic assessment tools, develop draft reports, solicit Public Comment, revise draft documents based on public input, TCEQ adoption of the draft documents, and EPA approval. It should be noted that the IR is considered draft until it is approved by EPA.
