[FRL-5509-7]
Guidelines Establishing Test Procedures for the Analysis of Oil
and Grease and Total Petroleum Hydrocarbons: Reopening of Comment
Period
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice; reopening of comment period.
-----------------------------------------------------------------------
SUMMARY: The U.S. Environmental Protection Agency (EPA) is reopening
the comment period for the proposal to amend the Guidelines
Establishing Test Procedures under section 304(h) of the Clean Water
Act to replace existing gravimetric test procedures for the
conventional pollutant ``oil and grease'' with EPA Method 1664, which
was published in the Federal Register on January 23, 1996 (61 FR 1730).
The public comment period for the proposed rule ended on March 25,
1996.
EPA has received several requests for an extension of time to
comment on the proposed rule, on the grounds that several issues that
the rule addresses require additional time for a proper evaluation. The
Agency has determined that an extension of time is in the public
interest, and that an additional 60 days to comment on the proposed
rule is reasonable.
DATES: Comments on this proposal will be accepted until July 23, 1996.
ADDRESSES: Send written comments on the proposed rule to ``Method
1664'' Comment Clerk; Water Docket MC-4101; Environmental Protection
Agency; 401 M Street, S.W.; Washington, D.C. 20460. Commenters are
requested to submit any references cited in their comments. Commenters
are also requested to submit an original and 3 copies of their written
comments and enclosures. Commenters who want receipt of their comments
acknowledged should include a self addressed, stamped envelope. All
comments must be postmarked or delivered by hand by July 23, 1996. No
facsimiles (faxes) will be accepted.
FOR FURTHER INFORMATION CONTACT: Mr. Ben Honaker, Engineering and
Analysis Division (4303), USEPA Office of Science and Technology, 401 M
Street, S.W., Washington, D.C., 20460, or call (202) 260-2272.
SUPPLEMENTARY INFORMATION: On January 23, 1996, EPA published a
proposed rule at 61 FR 1730 to replace existing gravimetric 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). This proposal would withdraw approval of EPA
Method 413.1 and Standard Methods Method 5520B, which use CFC-113 as
the extraction solvent. In an effort to provide for the use and
depletion of existing laboratory stocks of CFC-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
was also proposed for the determination of total petroleum
hydrocarbons.
This extension of time for comment neither represents any
modification of the proposed rule, nor indicates a change in the
Agency's interpretation of the existing requirements. The extension of
time for receipt of comments simply provides those interested parties
an additional 60 days to provide comments to the Agency on the proposed
rule. All other requirements stipulated in the initial proposal for
receipt of comments still apply.
All written comments submitted in accordance with the instructions
in the Notice of Proposed Rulemaking and received by July 23, 1996,
including those received between the close of the comment period on
March 25, 1996, and the publication of this notice, will be entered
into the public record and considered by EPA before promulgation of the
final rule.
Dated: May 17, 1996.
Robert Perciasepe,
Assistant Administrator for Water.
