              FINAL RULE FOR THIRD THIRD
              SCHEDULED WASTES COMPLETES
              STATUTORY REQUIREMENTS FOR
              LAND DISPOSAL RESTRICTIONS

        The fifth in a series of five Land Disposal Restrictions (LDR) rulemakings
      establishes treatment standards and effective dates for "Third Third" wastes, including
      characteristic wastes, and soft hammer wastes from the First and Second Third lists.
      The treatment standards apply to hazardous wastes that are land disposed, including
      those that are injected into deep wells. The Environmental Protection Agency (EPA) is
      granting, at a minimum, a three-month national capacity variance for all wastes
      affected by this rule to provide industry with time needed to comply with the new
      regulations.

BACKGROUND
The 1984 amendments to the Resource Conservation and Recovery Act
(RCRA) required EPA to establish treatment standards for all
hazardous wastes destined for land disposal. These standards must
specify a level or method of treatment which substantially reduces the
toxicity or mobility of the hazardous constituents so as to minimize
long-term threats to human health and the environment.

Congress specified strict dates when particular groups of hazardous
wastes not meeting the treatment standards are prohibited from land
disposal unless the Agency finds that  there will be "no migration of
hazardous constituents...for as long as the wastes remain hazardous."
With this rulemaking, the Agency has met all of the statutory deadlines
imposed by  Congress:

   •   On November 7, 1986, spent solvent and dioxin-bearing wastes
      were regulated.

   •   On July 8, 1987, the "California List"* wastes were addressed.

   •   Except for those wastes in today's rulemaking, all other wastes
      listed  as of November 8, 1984 were included in the land disposal
      restrictions on August 8, 1988 (First Third) and June 8, 1989
      (Second Third).
"California List" wastes are liquid and nonliquid hazardous wastes containing halogenated organic compounds
(HOCs) above 1,000 ppm, and liquid hazardous wastes containing polychlorinated biphenyls (PCBs) above 50 ppm,
certain toxic metals above specified statutory concentrations, or corrosive liquid wastes that have a pH level below
two.

-------
The land ban provisions will change the way that industry must man-
age their hazardous waste and has given considerable impetus to the
development of more economic and effective means of treating waste.
As a result, treatment technologies have improved rapidly and include
methods to destroy, detoxify, or incinerate waste. In addition, hazard-
ous waste generators have developed new ways to recover and reuse
waste as well as methods to reduce the volume of hazardous waste
requiring treatment.

ACTION
The final rule specifies treatment standards and effective dates for all
Third Third waste, characteristic wastes, First and Second Third soft
hammer wastes, and five  newly listed wastes. EPA also is promulgat-
ing treatment standards for multi-source leachate and mixed hazard-
ous/radioactive waste, and  is promulgating alternate treatment stan-
dards for lab packs. The Agency has rescheduled wastes from the pe-
troleum refining industry to the Third Third and is revising existing
standards for these wastes.  Previously promulgated treatment stan-
dards expressed as "110 land disposal" for nonwastewaters are being
replaced with treatment levels or specified methods.

The effective date of the rule is May 8, 1990. However, EPA is grant-
ing, at a minimum, a three-month national capacity variance to the
treatment standards for all  wastes affected by this rule to allow the
regulated community sufficient time to make necessary changes to
comply with the regulations. During the period of variance, wastes
that are placed in a Landfill  or into surface impoundments and do not
meet the treatment standards, must be disposed of in units that meet
the minimum technological requirements of Section 3004(o) of RCRA
(e.g., ground-water monitoring and leachate collection) and comply
with the recordkeeping requirements of 40 CFR 268.7.

For the characteristic wastes, EPA is specifying treatment levels below
the characteristic for the  EP toxic pesticide nonwastewaters and reac-
tive cyanides. In addition, the Agency is specifying methods that re-
quire treatment below the characteristic level for high TOC ignitables
and for EP toxic pesticide wastewaters.  Concentrations are specified
at the characteristic level for the EP toxic metals except for selenium,
which is slightly higher than the EP level. For corrosive and remaining
igriitable and reactive;, the standards require that wastes be treated so
that they no longer exhibit a characteristic.

The dilution prohibition developed for listed wastes is extended to
characteristic wastes included in the Third Third. However, the final
rule does not prohibit dilution of characteristic wastes that are gener-
ated and managed in wastewater treatment systems regulated under
the Clean Water Act or underground injection wells regulated under
the Safe Drinking Water Act. Prohibited wastes that are treated by
                                2

-------
 inappropriate methods or sent to treatment systems that do not treat
 the wastes are considered impermissibly diluted.

 With regard to characteristic wastes, dilution is permissible when
 wastes are aggregated for legitimate treatment in centralized treat-
 ment systems.

 Treatment standards for characteristic wastes require the following:

    •  Wastes that carry more than one characteristic waste code
      must be treated to meet the standard for each characteristic.
      Listed wastes that exhibit hazardous characteristics must meet
      the treatment standard for each waste code, unless each
      characteristic is specifically addressed in the treatment stan-
      dard for the listed waste. In addition, land disposal of a waste
      that exhibits a characteristic is prohibited. The only exception
      to this standard is selenium where the data only supports a
      treatment level above the characteristic.

    •  During the period of a national capacity variance, hazardous
      wastes that are subject to more than one treatment standard
      must still meet the treatment standard for any waste that has
      not received an extension.

    •  The use of the Toxicity Characteristic Leaching Procedures
      (TCLP)  in assessing whether a waste is subject to the Third
      Third land ban rule.

The Agency is promulgating alternate treatment standards for lab
packs that contain certain prohibited organometallic and organic
wastes. These standards are expressed as a specified technology for
each of the waste categories. For the organometallic wastes, incinera-
tion, followed by treatment to meet the treatment standards for metals
(included in the alternate standard) is required. For organic wastes in-
cineration is a specified method. Generators and owners/operators
who use the alternate treatment standards for lab pack wastes are re-
quired to list each waste code on the notification.

Due to inadequate treatment capacity for mixed hazardous/radioac-
tive wastes included in the Third Third,  EPA is granting a two-year
national capacity variance for these wastes. Those hazardous wastes
listed in the attached tables also are receiving a two-year national
capacity variance. Furthermore, the Agency is granting wastes from
the petroleum refining industry—EPA hazardous waste numbers
K048-K052—a six-month national capacity variance.

-------
EPA amended  40 CFR 268.7 to allow referencing treatment standards
for all wastes except spent solvents, California List wastes, and multi-
source leachate. The following information must be included in the
reference: EPA hazardous waste number, subcategory of the waste
code, treatability group, and CFR section where the treatment stan-
dards appear. In addition, EPA is allowing a one-time notification and
certification for small quantity generator shipments that are subject to
tolling agreements.

EPA promulgated waste analysis plan requirements for wastes treated
in 90-day tanks or containers. Persons treating prohibited wastes to
comply with treatment standards in such tanks and containers are
required to prepare a plan justifying the frequency of testing and
adhere to recordkeeping requirements.

CONCLUSION
The land disposal restrictions imposed by this rule completes the
Agency's assessment of all hazardous waste as required by the Haz-
ardous and Solid Waste Amendments (HSWA). Treatment standards
have been established for all listed and characteristic wastes that
existed when HSWA was enacted in 1984. Restricting the land dis-
posal of wastes covered by this final rule will create significant
changes in hazardous waste management, thereby minimizing threats
to human health and the environment.
