Amended February 2004
Justification: This document details the modification made to the basin-wide Quality Assurance Project Plan to update Table A7.1, Measurement Performance Specifications, to reflect additional EPA methods used in laboratory analyses by the Red River Authority of Texas Regional Laboratory and to update certain parameters and EPA methods performed by the CRMWA and LCRA laboratories.
Summary of Changes: The following information in Amendment I is amended to add the following changes:
• Revision of Table A7.1 – Measurement Performance Specifications
• Addition of Chemical Water Analysis and E. Coli Bacteria Log Forms to QAPP Appendices
Detail of Changes: The addition of Red River Authority’s Regional Laboratory conducting analysis of Chlorophyll a and Pheophytin by EPA Method 446.0; the analysis of Ortho Phosphate-P, Nitrite-N, Nitrate-N, Sulfate, Chloride, and Fluoride by EPA method 300.0; and the analysis of Ammonia-N by EPA method 350.3. In addition, Fecal Coliform will be added back to Table A7.1 and Total Hardness, Storet Codes 00900 and 82394 will be removed from the table for RRA. Also included in the update of TableA7.1 is the addition of EPA method 300.0 for the analysis of Ortho Phosphate-P, Nitrate-N, Sulfate, and Chloride, and Fluoride by the storet code 00950 has been removed from the table for the Canadian River Municipal Water Authority (CRMWA) Laboratory. In addition SM 9223-B for the analysis of E. coli by CRMWA has been added. A change in the EPA method number for Nitrite/Nitrate-N from 353.3 to 353.2 and changes to the method numbers for Chlorophyll a and Pheophytin to EPA Method 446.0, with a back-up method of SM 10200H, as performed by the Lower Colorado River Authority laboratory has also been made to Table A7.1. In addition, a newly developed storet code of 20424 has been added for Water Clarity to Table A7.1 under Field Parameters. Additionally, Chemical Water Analysis and E. coli Bacteria Log forms to be submitted by CRMWA have been added to Appendix C (see attached).
These changes will be incorporated into the Quality Assurance Project Plan for the Red and Canadian River Basins for FY 2004 – FY 2005. The Texas Commission on Environmental Quality and the Red River Authority of Texas will acknowledge and accept these changes by signing this amendment.
