Whole Effluent Toxicity: Guidelines Establishing Test Procedures for the Analysis of Pollutants

This final rule amends the ``Guidelines Establishing Test Procedures for the Analysis of Pollutants,'' 40 CFR part 136, to add whole effluent toxicity (WET) testing methods to the list of Agency approved methods in Tables IA and II, under the Clean Water Act. This action amends 40 CFR 136.3 (Tables 1A and II) by adding methods for measuring the acute and short-term chronic toxicity of effluents and receiving waters. This rulemaking was initiated at the request of the States. The overall benefit of today's rulemaking is that it will reduce costs and eliminate the confusion caused by the multiple versions of any one test method currently in use. For example, currently, an industry with facilities in six different states may be required to conduct six different versions of the same test method. EPA estimates that standardizing these approved methods could save the regulated community up to 20% of the current test method costs, which range from $160.00- $2240.00, depending upon the test method. This rulemaking will also reduce the current resource burden in the States because they will no longer need to justify the inclusion of WET monitoring or WET limits in National Pollution Dischar
