Land Disposal Restrictions; Treatment Standards for Spent 
Potliners From Primary Aluminum Reduction (K088) and Regulatory 
Classification of K088 Vitrification Units

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule; reopening of the comment period.

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

SUMMARY: On July 12, 2000 (65 FR 42937), EPA issued a proposed rule 
presenting potential revisions to the Land Disposal Restrictions 
treatment standards applicable to spent potliners from primary aluminum 
reduction (EPA hazardous waste: K088). The proposal requested comment 
on the proposed treatment standards, the Agency's proposal to classify 
K088 vitrification units as RCRA subpart X miscellaneous treatment 
units, and the appropriateness of extending the rational proposed for 
K088-vitrification units to all vitrification units treating RCRA 
hazardous waste. The Agency is extending the comment period because 
several commenters have requested more time to address the issues 
raised in the proposal, and to generate data on hazardous 
concentrations in untreated and treated K088 waste. This document 
extends the comment period for the proposed rule.

DATES: The comment period for this proposed rule is extended from the 
original closing date of September 11, 2000 to December 11, 2000.

ADDRESSES: If you wish to comment on this notice of proposed rulemaking 
(NPRM), you must send an original and two copies of the comments 
referencing docket number F-2000-TSSP-FFFFF to: RCRA Docket Information 
Center, Office of Solid Waste (5305G), U.S. Environmental Protection 
Agency Headquarters (EPA, HQ), Ariel Rios Building, 1200 Pennsylvania 
Avenue, NW, Washington, D.C. 20460. Hand deliveries of comments should 
be made to the Arlington, VA, address listed below. You may also submit

voluntarily submit one additional copy of their comments on labeled 
personal computer diskettes in ASCII (text) format or a word processing 
format that can be converted to ASCII (text). It is essential to

edition as well as the commenter's name. This will allow EPA to convert 
the comments into one of the word processing formats utilized by the 
Agency. Please use mailing envelopes designed to physically protect the 
submitted diskettes. EPA emphasizes that submission of comments on 
diskettes is not mandatory, nor will it result in any advantage or 
disadvantage to any commenter.
    You should not submit electronically any confidential business 
information (CBI). You must submit an original and two copies of CBI 
under separate cover to: RCRA CBI Document Control Officer, Office of 
Solid Waste (5305W), U.S.
