| 98-17963 | Guidelines Establishing Test Procedures for the Analysis of Pollutants; Available Cyanide | Proposed Rule | This proposed regulation would amend the Guidelines Establishing Test Procedures for the Analysis of Pollutants under Section 304(h) of the Clean Water Act by adding Method OIA-1677: Available Cyanide by Flow Injection, Ligand Exchange, and Amperometry. Method OIA-1677 employs flow injection analysis (FIA) to measure ``available cyanide.'' Method OIA-1677 is being proposed as an additional test procedure for measuring the same cyanide species as are measured by currently approved methods for cyanide amenable to chlorination (CATC). In some matrices, CATC methods are subject to significant test interferences. In contrast, Method OIA-1677 demonstrates greater specificity for cyanide for matrices in which interferences have been encountered using CATC methods. In addition, Method OIA-1677 measures cyanide at lower concentrations and offers improved precision and accuracy over currently approved CATC methods. Method OIA-1677 also offers improved laboratory safety and reduces laboratory waste compared to currently approved CATC methods. This significantly reduces the generation of hazardous waste by the laboratory. Cyanide analysis by Method OIA-1677 is also more rapid than by currently approved methods. | 1998-07-07 | 1998 | 7 | https://www.federalregister.gov/documents/1998/07/07/98-17963/guidelines-establishing-test-procedures-for-the-analysis-of-pollutants-available-cyanide | https://www.govinfo.gov/content/pkg/FR-1998-07-07/pdf/98-17963.pdf | Environmental Protection Agency | 145 | This proposed regulation would amend the Guidelines Establishing Test Procedures for the Analysis of Pollutants under Section 304(h) of the Clean Water Act by adding Method OIA-1677: Available Cyanide by Flow Injection, Ligand Exchange, and... |
