ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 261

[FRL-5546-4]


Hazardous Waste Management System; Identification and Listing of 
Hazardous Waste; Final Exclusion; Correction

AGENCY: Environmental Protection Agency.

ACTION: Final rule; Correction.

-----------------------------------------------------------------------

SUMMARY: On July 18, 1996, the Environmental Protection Agency (EPA or 
Agency) published a final rule granting a petition submitted by United 
Technologies Automotive, Inc. (UTA), Dearborn, Michigan, to exclude (or 
``delist''), conditionally, on a one-time, upfront basis, a certain 
solid waste generated by UTA's chemical stabilization treatment of 
lagoon sludge at the Highway 61 Industrial Site in Memphis, Tennessee, 
from the lists of hazardous wastes in Secs. 261.31 and

[[Page 40520]]

261.32. Based on careful analyses of the waste-specific information 
provided by the petitioner, the Agency concluded that UTA's petitioned 
waste will not adversely affect human health and the environment. 
Delisting levels for cadmium, chromium, lead, nickel, and cyanide which 
would be protective of human health and the environment were calculated 
and promulgated. This action addresses the fact that the calculated 
level of 9.6 mg/l of chromium in the TCLP extract is greater than the 
toxicity characteristic (TC) level of 5.0 mg/l (see 40 CFR 261.24). A 
waste exhibits the TC for chromium, and is, therefore, a hazardous 
waste, if its TCLP extract contains greater than or equal to 5.0 mg/l 
of chromium. Therefore, today's notice corrects the delisting level for 
chromium by requiring the concentration of chromium in a TCLP extract 
of UTA's petitioned waste to be less than 5.0 mg/l. This action also 
addresses the fact that the calculated level for cyanide was 19.2 mg/l 
in a TCLP extract of the petitioned waste. In order to be consistent 
with previous delistings, cyanide should be measured in a waste extract 
obtained by using deionized water as the extraction medium, rather than 
the acetic acid of the TCLP. (See, for example, 56 FR 33004-33005, 
33012, July 18, 1991; and 56 FR 67199, 67208, December 30, 1991.) 
Therefore, today's notice corrects the delisting level for cyanide by 
requiring the cyanide extraction to be conducted using deionized water.

EFFECTIVE DATE: July 18, 1996.

notice is located at the EPA Library, U.S. Environmental Protection 
Agency, Region 4, 345 Courtland Street, N.E., Atlanta, Georgia 30365,

SUPPLEMENTARY INFORMATION:

I. Reasons and Basis for This Action

    Although 40 CFR 260.22 requires a petitioner to demonstrate that 
the petitioned waste does not exhibit any of the characteristics in 
Sec. 261.21, Sec. 261.22, Sec. 261.23, and Sec. 261.24, and that a 
waste excluded in accordance with Sec. 261.22 may still be a hazardous 
waste under Subpart C of Part 261, today's notice changes the delisting 
level for chromium to below the regulatory level for the toxicity 
characteristic (TC) in Sec. 261.24, in order to ensure that the 
petitioned waste does not exhibit the TC and to clarify that no waste 
which exhibits the TC is allowed to be disposed in a Subtitle D 
facility.
    The calculated level of 9.6 mg/l for chromium in the final rule 
resulted from the fact that the maximum contaminant level (MCL) for 
chromium, established by the Safe Drinking Water Act, was changed from 
0.05 mg/l to 0.10 mg/l (see 56 FR 3526-3597, January 30, 1991). The TC 
levels in Sec. 261.24, which equal 100 x the appropriate MCL at the 
time of their promulgation, have not been changed to be consistent with 
current MCL values.
    As stated in the Summary paragraph of today's correction notice, in 
order to be consistent with previous delistings, cyanide should be 
measured in a waste extract obtained by using deionized water as the 
extraction medium, rather than the acetic acid of the TCLP. (See, for 
example, 56 FR 33004-33005, 33012, July 18, 1991; and 56 FR 67199, 
67208, December 30, 1991.) Therefore, today's notice corrects the 
delisting level for cyanide by requiring the cyanide extraction to be 
conducted using deionized water.

II. Corrections to the Final Rule

    A. On page 37401, of the Federal Register of July 18, 1996, Table 1 
of the Preamble:
    The delisting level for chromium is corrected to read: ``9.6; 
delisting level is set at less than 5.0, the toxicity characteristic 
level.''
    The delisting level for cyanide is corrected to read: ``19.2; 
(cyanide extraction must be conducted using deionized water.)''
    B. On page 37402, Table 1 of Appendix IX of Part 261:
    Condition (3) is corrected to read: ``(3) Delisting Levels: All 
leachable concentrations for these constituents must not exceed the 
following levels (ppm): Cadmium--0.48; cyanide--19.2; lead--1.4; and 
nickel--9.6. The leachable concentration of chromium must be less than 
5.0 ppm. Metal concentrations in the waste leachate must be measured by 
the method specified in 40 CFR 261.24. The cyanide extraction must be 
conducted using deionized water. Total cyanide concentration in the 
leachate must be measured by Method 9010 or Method 9012 of SW-846.''
