| 96-877 | Guidelines Establishing Test Procedures for the Analysis of Oil and Grease and Total Petroleum Hydrocarbons | 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 to replace existing gravimetric test procedures for the conventional pollutant ``oil and grease'' (40 CFR 401.16) with EPA Method 1664 as part of EPA's effort to reduce dependency on the use of chlorofluorocarbons (CFCs). Method 1664 uses normal hexane (n-hexane) as the extraction solvent in place of 1,1,2- trichloro-1,2,2-trifluoroethane (CFC-113; Freon-113). CFC-113 is used in currently approved 40 CFR Part 136 methods for the determination of oil and grease. These methods are EPA Method 413.1 in Methods for Chemical Analysis of Water and Wastes (EPA-600/4-79-020) and Method 5520B in Standard Methods for the Examination of Water and Wastewater, 18th edition. This proposal would withdraw approval of Methods 413.1 and 5520B to preclude the unacceptable inconsistency between results produced by such methods and proposed Method 1664. In an effort to provide for the use and depletion of existing laboratory stocks of Freon-113, EPA plans to implement the required use of Method 1664 no sooner than six months after the final rule is published in the Federal Register. Method 1664 is also being proposed for the determination of total petroleum hydrocarbons. | 1996-01-23 | 1996 | 1 | https://www.federalregister.gov/documents/1996/01/23/96-877/guidelines-establishing-test-procedures-for-the-analysis-of-oil-and-grease-and-total-petroleum | https://www.govinfo.gov/content/pkg/FR-1996-01-23/pdf/96-877.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 to replace existing gravimetric test procedures for the conventional pollutant ``oil and... |
