Environmental Protection Agency 40 CFR Part 141 [OW-2003-0067; FRL-7805-5 ] RIN 2040-AE62 AGENCY: Environmental Protection Agency (EPA). ACTION: Final rule. SUMMARY: The Environmental Protection Agency (EPA) is taking final action to approve the use of three additional analytical methods for compliance determinations of uranium in drinking water. These methods use an inductively coupled plasma mass spectrometry (ICP-MS) technology that has gained wide acceptance in the analytical community. EPA believes that ICP-MS analytical methods could be more cost-effective, less labor-intensive or more sensitive than some of the technologies previously approved in the December 2000 Radionuclides rule. ( 65 FR 76708 ) This rule does not withdraw approval of any previously approved monitoring methods for uranium. DATES: This rule is effective on August 25, 2004.
