Land Disposal Restrictions--Phase IV: Issues Associated With 
Clean Water Act Treatment Equivalency, and Treatment Standards for Wood 
Preserving Wastes and Toxicity Characteristic Metal Wastes

AGENCY: Environmental Protection Agency (EPA, the Agency).

ACTION: Proposed rule; correction.

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

SUMMARY: On August 22, 1995, EPA published a proposed rule that 
presented three approaches for addressing whether wastewater treatment 
surface impoundments receiving decharacterized wastes provide treatment 
that is equivalent to that provided under the land disposal 
restrictions (LDR) program. The approaches focused on whether hazardous 
constituents are treated to the same extent as would occur under the 
LDR program. One of the options presented, option 2, included 
flowcharts that should facilitate the public's understanding of the 
approach. An error was found in the flowchart, and this error is 
corrected in today's notice. The Agency is also pointing out 
inconsistencies between the UTS Tables at 60 FR 43682 and 43696, which 
are not in agreement with regard to the list of constituents proposed 
for regulation in F032, F034, and F035 and the universal treatment 
standards proposed for several of the constituents. Two errors were 
also identified in the proposed treatment standards in the table at 
43682. These will be corrected in today's notice.

ADDRESSES: Copies of the proposed rule can be obtained from the RCRA 
Docket (5305), U.S. Environmental Protection Agency, Room 2616, 401 M 
Street, SW., Washington, DC 20460. The RCRA Docket is open from 9:00 am 
to 4:00 pm Monday through Friday, except for federal holidays. The 
public must make an appointment to review docket materials by calling 
[phone]. The public may copy a maximum of 100 pages from any 
regulatory document at no cost. Additional copies cost $0.15 per page.

FOR FURTHER INFORMATION CONTACT: For general information contact the 
RCRA Hotline at [phone] (toll free) or [phone] in the 
Washington, DC metropolitan area. For technical information about the 
correction to the flowchart, contact Elaine Eby (5302W), Office of 
Solid Waste, 401 M Street, SW., Washington, DC 20460, [phone], 
or Mary Cunningham at [phone]. For technical information on the 
F032, F034, F035 treatment standards, contact Jose Labiosa at (703) 
308-8464.

SUPPLEMENTARY INFORMATION:

I. Reasons and Basis for Today's Notice

    The Agency has noticed certain portions of the August 22, 1995 
Proposed Rule are in error. Today's notice corrects those errors. The 
Agency has not done a comprehensive proofreading of the proposed rule, 
so it is possible there are other errors that are not addressed by this 
correction notice. The Agency believes they would be inconsequential, 
however, and would not affect commenters' ability to understand the 
proposal. If questions arise that are not addressed by this correction 
notice, call the RCRA Hotline or the appropriate contact listed in the 
Phase IV proposed rule.

II. Corrections to the Phase IV Proposed Rule

A. Figure 2: Option 2 Flowchart

    The Agency is today revising the flowchart titled ``Figure 2: 
Option 2--Applicability Criteria and Management Standards for Air 
Emissions.'' The previous flowchart for the Option 2 air emission 
standards showed an oversimplification of the RCRA Subpart CC 
provisions. In order to eliminate confusion, EPA has subsequently 
revised the flowchart to show more clearly that this option would 
extend, but would not change, the RCRA Subpart CC standards, and to 
refer the reader directly to those standards. In addition, EPA is 
clarifying that Subpart CC does not require implementation of air 
emission controls for biological treatment surface impoundments which 
are operated at the requisite efficiency.

B. Table, ``Proposed BDAT Standards for F032, F034, F035''

    Where inconsistencies exist in UTS tables at 60 FR 43682 and 43696, 
EPA is directing the reader to the proposed list of regulated 
constituents and the proposed UTS limits in the table at 60 FR 43682 as 
being correct. Comments on the UTS limits in the proposed rule should 
refer to this particular table. The UTS table at 43696 is in error for 
these wastes.
    The following changes are also made to the table on page 43682:
     For 2, 4-Dimethylphenol, the BDAT Standard for Wastewaters 
is corrected to read, ``0.036 mg/l;''
     For 2, 3, 4, 6-Tetrachlorophenol, the BDAT Standard for 
Wastewater is corrected to read, ``0.030 mg/l.''
