2. 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.

3. 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.

Updated\Revised Water Quality Standards
Data collected during extreme high flow conditions
Other Assessment Method Changes
For the 2018 Integrated Report we will be looking at updating nutrient assessment methods is necessary, incorporating and revised water quality standards from the 2018 revision, refining the drought assessment method and evaluating how to evaluated data collected during extreme hydrologic events.

14. 2018 Integrated Report Next Steps
Advisory Workgroup Meeting
Data Assessment
The next steps for the 2018 Integrated Report include convening the Guidance Advisory Workgroup and developing the guidance. We will also be conducting the data assessment.
