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.

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.
