Appendix A: 2012 Integrated Report of Water Quality in Louisiana   The preceding two files contain Louisiana's FINAL DRAFT 2012 Integrated Report-Water Quality Assessments pending EPA Region 6 final decision.

Appendix B: 2012 Integrated Report of Water Quality in Louisiana - Revisions to original draft 2012 Integrated Report  

Appendix C: 2012 Integrated Report of Water Quality in Louisiana - Category 1 Addendum   Appendix C contains water bodies and suspected causes of impairment that were formerly considered impaired in previous Integrated Reports. They are no longer considered to be impaired by Louisiana. More recent data or information was used to make this determination during the 2012 Integrated Report assessment process. Appendix C is used here as a tool to track changes to the Integrated Report over time.

Appendix D: Complete list of suspected causes of impairment  

Appendix E: Complete list of suspected sources of impairment 

Appendix F: Complete listing of Louisiana's Ambient Surface Water Quality Network Sites 

Appendix G: Public Comments on the 2012 Integrated Report and LDEQ's Response to Comments

  Appendix G is a compilation of all comments received regarding the 2012 Integrated Report, along with LDEQ's response to those comments.

Appendix H: Louisiana's 2012 Section 303(d) List   Appendix H represents a subset of Louisiana's 2012 Integrated Report (IR) and includes only those water body impairment combinations (WICs) reported as Category 5. As has been noted in the body of the IR text, WICs in Category 5 of the IR assessments are the only WICs on Louisiana's 2012 303(d) List. This table was developed only as an aid to the public and does not constitute Louisiana's 303(d) List. Every effort was made to maintain consistency between Appendix A Category 5 WICs and Appendix H. However, in order to ensure the accuracy of the overall Integrated Report only those WICs in Appendix A, Category 5, constitute the official 2012 303(d) List.
