Glossary and References 

Appendix A - Statewide Water Quality Assessments    

  • This document contains the complete and FINAL 2004 Integrated Report along with EPA Region 6's additions to Louisiana's 303(d) List. In March 2005, EPA issued a Decision Document amending Louisiana's 303(d) List. These additional impairments are included in this appendix and highlighted in yellow. EPA is responsible for developing TMDLs for these suspected impairments because Louisiana does not agree with EPA's assessments

Appendix B - 2004 Integrated Report of Water Quality in Louisiana - Addendum

Appendix C - 2004 Integrated Report of Water Quality in Louisiana - Category 1 Addendum

  • Appendix C contains water bodies and suspected causes of impairment that were formally 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 2004 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 and cause descriptions used in U.S. EPA's Assessment Database

Appendix E - Complete list of suspected sources of impairment and source descriptions used in U.S. EPA's Assessment Database

Appendix F - Complete Listing of all Ambient Surface Water Quality Network Sites

Appendix G - Public Comments on the 2004 Integrated Report and LDEQ's Response to Comments

  • Appendix G is a compilation of all comments received regarding the 2004 Integrated Report, along with LDEQ's response to those comments. Any changes made to the 2004 Integrated Report based on public comments are noted in the column entitled, Summary of LDEQ Responses.

Appendix H - Louisiana's 2004 303(d) List

  • Appendix H represents a subset of Louisiana's 2004 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 2004 303(d) List. This table was developed only as an aid to the public, at the request of Gulf Restoration Network, 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 303(d) List.
