    Guidelines Establishing Test Procedures for the Analysis of 
    Pollutants: New Methods; Reopening of Comment Period
    
    AGENCY: Environmental Protection Agency (EPA).
    
    ACTION: Proposed rule; reopening of comment period.
    
    -----------------------------------------------------------------------
    
    SUMMARY: The U. S. Environmental Protection Agency (EPA) is reopening 
    the comment period for the proposed guidelines establishing new 
    analytical methods for use under the Clean Water Act, which were 
    published in the Federal Register on October 18, 1995 (60 FR 53988). 
    The public comment period for the proposed rule was to end on December 
    18, 1995.
    
    DATES: Comments on the proposed guidelines will be accepted until April 
    2, 1996.
    
    ADDRESSES: Comments should be submitted by mail to the 304(h) Docket 
    Clerk (Ben Honaker), Water Docket (MC-4101), U.S. EPA, 401 M. Street 
    SW., Washington, DC 20460.
    
    FOR FURTHER INFORMATION CONTACT: Mr. James Longbottom, Aquatic Research 
    Division, National Exposure Research Laboratory, Office of Research and 
    Development, U.S. Environmental Protection Agency, Cincinnati, Ohio 
    45268. Telephone number: (513) 569-7308.
    
    SUPPLEMENTARY INFORMATION: The methods proposed for addition on October 
    18, 1995, (60 FR 53988) include new methods for: preparation of samples 
    for metals analysis, inductively coupled plasma/mass spectrometry (ICP/
    MS), a stabilized temperature graphite furnace atomic absorption 
    (STGFAA) method for metals, and ion chromatography (IC) methods for 
    anions and hexavalent chromium [Cr(VI)]. A revised EPA inductively 
    coupled plasma atomic emission spectrometry (ICP-AES) method for metals 
    to replace the currently approved method, and an extension of the 
    approved method for the determination of low level total residual 
    chlorine were also proposed. The specific methods included in the 
    rulemaking are as follows: EPA Methods 180.1, 200.7, 200.8, 200.9, 
    218.6, 300.0, 611, and 625; SMEWW, Method 4500-CL E; and Standard 
    Methods Method 6410B.
        All written comments submitted in accordance with the instructions 
    in the Notice of Proposed Rulemaking and received by April 2, 1996, 
    including those received between the close of the comment period on 
    December 18, 1995, and the publication of this notice will be entered 
    into the public record and considered by EPA before promulgation of the 
    final rule.
    
        Dated: January 23, 1996.

    Assistant Administrator, Office of Water.
