Land Disposal Restrictions Phase III--Decharacterized Wastewaters, 
Carbamate Wastes, and Spent Potliners

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: EPA is promulgating treatment standards for hazardous wastes 
from the production of carbamate pesticides and from primary aluminum 
production under its Land Disposal Restrictions (LDR) program. The 
purpose of the LDR program, authorized by the Resource Conservation and 
Recovery Act (RCRA), is to minimize short- and long-term threats to 
human health and the environment due to land disposal of hazardous 
wastes.
    The Agency is also amending the treatment standards for hazardous 
wastes that exhibit the characteristic of reactivity. The rule also 
begins the process of amending existing treatment standards for 
wastewaters which are hazardous because they display the characteristic 
of ignitability, corrosivity, reactivity, or toxicity. These wastes are 
sometimes treated in lagoons whose ultimate discharge is regulated 
under the Clean Water Act, and sometimes injected into deepwells which 
are regulated under the Safe Drinking Water Act. Prior to today's rule, 
the treatment standard for these wastes required only removal of the 
characteristic property. Today's revised treatment standards require 
treatment, not only to remove the characteristic, but also to treat any 
underlying hazardous constituents which may be present in the wastes. 
Therefore, these revised treatment standards will minimize threats from 
exposure to hazardous constituents which may potentially migrate from 
these lagoons or wells.
    Finally, EPA is codifying as a rule its existing Enforcement Policy 
that combustion of inorganic wastes is an impermissible form of 
treatment because hazardous constituents are being diluted rather than 
effectively treated.

EFFECTIVE DATE: This final rule is effective on April 8, 1996, except:
    Sections 148.18(a), 268.39(a), (b), and (f), which are effective on 
July 1, 1996; and
    Sections 148.18(b) and 268.39(c), which are effective on January 8, 
1997; and
    Sections 148.1 (a), (b), and (d), 148.3, 148.4, 148.18 (c) and (d), 
148.20(a), 268.1(e), 268.2 (k) and (l), 268.3 (a) and (b), 268.9 (d), 
(e), (f), and (g), 268.39 (d) and (e), 268.44(a), and 403.5 (c) and 
(d), which are effective on April 8, 1998.

I. Background

A. Summary of the Statutory Requirements of the 1984 Hazardous and 
Solid Waste Amendments, and Requirements of the 1993 Consent Decree 
With the Environmental Defense Fund

    The Hazardous and Solid Waste Amendments (HSWA) to the Resource 
Conservation and Recovery Act (RCRA), enacted on November 8, 1984, 
largely prohibit the land disposal of untreated hazardous wastes that 
do not meet treatment standards established by EPA under section 
3004(m). Once a hazardous waste is prohibited, the statute provides 
only two options for legal land disposal: meet the treatment standard 
for the waste prior to land disposal, or dispose of the waste in a land 
disposal unit that has been found to satisfy the statutory no migration 
test. A no migration unit is one from which there will be no migration 
of hazardous constituents for as long as the waste remains hazardous. 
RCRA sections 3004 (d), (e), (f), (g)(5).
    The amendments also require the Agency to set levels or methods of 
treatment, if any, which substantially diminish the toxicity of the 
waste or substantially reduce the likelihood of migration of hazardous 
constituents from the waste so that short term and long term threats to 
human health and the environment are minimized. RCRA section 
3004(m)(1). To date, the Agency has implemented this provision by 
establishing treatment standards for chemical constituents in hazardous 
wastes based on the performance of the best demonstrated available 
technology (BDAT) to treat the waste. EPA may establish treatment 
standards as specified technologies, as constituent concentration 
levels in treatment residuals, or both. When treatment standards are 
set as levels, the regulated community may use any technology not 
otherwise prohibited (such as impermissible dilution) to treat the 
waste.
    It should be noted that the Agency has proposed risk-based exit 
levels--levels at which wastes are no longer considered hazardous for 
purposes of RCRA subtitle C--for the majority of hazardous constituents 
found in listed hazardous wastes in the Hazardous Waste Identification 
Rule (HWIR) (60 FR 66344, December 21, 1995). Wastes meeting these 
levels either before or after treatment consequently could be disposed 
in units not subject to RCRA hazardous waste management requirements 
(e.g., landfills without subtitle C permits). A consent decree approved 
by the U.S. District Court for the District of Columbia requires EPA to 
finalize the HWIR exit levels by December 15, 1996. In the same notice, 
the Agency proposed to allow the exit levels for some constituents to 
serve as alternative, risk-based LDR treatment standards satisfying the 
``minimize threat'' standard of section 3004(m). Where these risk-based 
levels are higher (less restrictive) than current BDAT treatment 
standards, they will effectively supersede the BDAT requirements. See 
Hazardous Waste Treatment Council v. EPA, 886 F.2d 355, 362-63 (D.C. 
Cir. 1989).
    EPA was required to promulgate land disposal prohibitions and 
treatment standards by May 8, 1990 for all wastes that were either 
listed or identified as hazardous at the time of the 1984 amendments 
(RCRA sections 3004 (d), (e), and (g)(5)), a task EPA completed within 
the statutory timeframe. EPA was also required to promulgate 
prohibitions and treatment standards for wastes identified or listed as 
hazardous after the date of the 1984 amendments within six months after 
the listing or identification takes effect (RCRA section 3004(g)(4)).
    The Agency did not meet this latter statutory deadline for all of 
the wastes identified or listed after the 1984 amendments. As a result, 
a suit was filed by the Environmental Defense Fund (EDF). EPA and EDF 
signed a consent decree that establishes a schedule for adopting 
prohibitions and treatment standards for newly identified and listed 
wastes. (EDF v. Reilly, Cir. No. 89-0598, D.D.C.). EPA also entered 
into a settlement agreement with the environmental petitioners in 
Chemical Waste Management v. EPA, 976 F.2d 2 (D.C. Cir. 1992), cert. 
denied 113 S. Ct. 1961 (1993) regarding the procedural effect of the 
mandate entered in that case. This settlement calls for EPA to take 
action to implement the portions of the opinion dealing with 
centralized management of wastewaters that initially exhibit a 
hazardous waste characteristic within specified timeframes.
    Today's rule fulfills several provisions of the settlement 
agreement and proposed consent decree. First, the rule amends the 
treatment standards for initially characteristic wastewaters managed in 
centralized wastewater management systems containing land disposal 
units. Three specific fact patterns are covered by the rule: (1) Where 
the wastewaters are ultimately discharged and are subject to 
limitations or standards established under the Clean Water Act (CWA) 
and the treatment system preceding discharge includes a surface 
impoundment; (2) where a facility with initially characteristic wastes 
treats those wastes with CWA-equivalent treatment but ultimately uses a 
form of land disposal (such as spray irrigation) that is not regulated 
under the CWA as the final means of disposing of the treated 
wastewaters; and (3) the initially characteristic wastes are injected 
into Class 1 non-hazardous deep wells subject to regulation under the 
Safe Drinking Water Act (SDWA). In all cases, the wastewaters no longer 
exhibit a characteristic at the point of land disposal. The amended 
treatment standards require treatment that destroys, immobilizes, or 
removes the hazardous constituents present in the initially 
characteristic wastewaters (referred to as ``underlying hazardous

[[Page 15568]]
constituents'' because these constituents are not typically the reason 
the waste is classified as hazardous). Treatment of the underlying 
hazardous constituents is nevertheless required in order to minimize 
the long-term threats land disposal of these wastes can cause. 976 F.2d 
at 16-17.
    EPA is fulfilling provisions of the consent decree by promulgating 
prohibitions and treatment standards for two ``newly listed wastes'' 
wastes from production of carbamate pesticides, and spent aluminum 
potliners from primary aluminum production.
    That being said, the risks addressed by the portion of the rule 
dealing with centralized wastewater management, particularly UIC wells, 
are very small relative to the risks presented by other environmental 
conditions or situations. In a time of limited resources, common sense 
dictates that we deal with higher risk activities first, a principle on 
which EPA, members of the regulated community, and the public can all 
agree. For this reason, the Administration is supporting HR 2036, 
legislation which passed the House of Representatives, that would 
remove the mandate to automatically apply LDR treatment standards to 
decharacterized wastes managed in centralized wastewater management 
situations regulated by the CWA or the SDWA. If this legislation passes 
in its current form, it would affect the regulations discussed in 
sections III., IV., and VI.B. of the preamble. It would not affect the 
other sections of the preamble and rule. The sections of preamble and 
rule that are affected by the legislation have been granted 2-year 
national capacity variance (see Secs. 148.18 (c) and (d) and 268.39 (c) 
and (d)). The sections of preamble and rule not affected by the 
legislation have more immediate effective dates. If the legislation 
does pass into law, the Agency could issue an immediately effective 
final rule remanding the affected portions.
    Nevertheless, the Agency is presently required to set treatment 
standards for these relatively low risk wastes and disposal practices, 
although there are other actions and projects with which the Agency 
could provide greater protection of human health and the environment. 
At the same time, however, EPA has sought to exercise the full extent 
of its authority under current law to implement these mandates with 
significantly lower cost while ensuring protectiveness, such as giving 
credit for up-stream reductions in hazardous constituents, and crafting 
limited exemptions for wastewaters containing de minimis amounts of 
hazardous constituents.

B. Treatment Standards for Hazardous Wastes That Exhibit a 
Characteristic--The D.C. Circuit's Opinion in Chemical Waste Management 
v. EPA

    In Chemical Waste Management v. EPA, 976 F.2d 2 (D.C. Cir. 1992) 
cert. denied 113 S. Ct. 1961 (1993), the court made a number of far-
reaching rulings pertaining to treatment standards for hazardous wastes 
that are hazardous because they exhibit a characteristic. First, the 
court held that land disposal restriction requirements can continue to 
apply to characteristic hazardous wastes even after they no longer 
exhibit a characteristic. 976 F.2d at 12-14. Second, to satisfy the 
requirement in RCRA section 3004(m) that treatment address both short-
term and long-term threats posed by a waste's land disposal, it is not 
enough that characteristic hazardous wastes be treated to remove the 
short-term property (viz. ignitability, corrosivity, or reactivity) 
that makes them hazardous. Long-term threats, in the form of toxic 
underlying hazardous constituents, also must be addressed. 976 F.2d at 
16-17. Third (as EPA reads the opinion), the court held that dilution 
was ordinarily not a permissible means of treating hazardous 
constituents. Such constituents generally must be destroyed, 
immobilized, or removed from the waste to satisfy the requirements of 
section 3004(m), specifically, the requirement that long-term threats 
be minimized. 976 F.2d at 23, 25 and n. 8; 60 FR at 11706-11708 (March 
2, 1995). Fourth, centralized wastewater management systems whose 
discharge is ultimately regulated under the Clean Water Act, and which 
dilute characteristic hazardous wastes before treatment in surface 
impoundments, may continue to do so provided the wastewater treatment 
system destroys, immobilizes, or removes the same volume of hazardous 
constituents as would be removed, immobilized, or destroyed if the 
wastes were treated separately. 976 F.2d at 22-24. In other words, 
notwithstanding that these wastes are disposed in impoundments without 
being fully treated, the practice is permissible provided equivalent 
treatment occurs before the waste is ultimately discharged. Fifth, this 
option of demonstrating equivalent treatment across a treatment system 
is not available for Class I nonhazardous deep well injection systems 
because such units are permanent disposal rather than treatment units. 
976 F.2d at 24-6.
    These portions of the opinion are addressed in various sections of 
today's rule.
    The Agency is also addressing the issue of equivalent treatment by 
Clean Water Act treatment systems managing de-characterized wastes in 
impoundments by promulgating treatment standards and related 
requirements that would be used to measure this so-called end-of-pipe 
equivalence. Finally, EPA is implementing the court's mandate with 
respect to Class I nonhazardous injection wells by requiring treatment 
of underlying hazardous constituents in ignitable, and corrosive 
characteristic wastes being injected into such wells, and prohibiting 
dilution as a means of achieving those standards.
    Responses to the comments on EPA's reading of the court's opinion 
are found in the Response to Comment Background Document which is part 
of the administrative record for this rule. In general, however, the 
Agency adheres to the reading set out in the proposed rule's preamble 
at 60 FR 11706-11708.
    EPA is also amending the treatment standards for reactive wastes 
(other than reactive sulfide and cyanide reactive wastes) so that 
treatment addresses both the property of reactivity and the threat 
posed by disposal of underlying hazardous constituents in these wastes 
(with an exception for ordnance and other explosives which are the 
subject of an emergency response, as explained in the next paragraph). 
The Agency is taking this action despite the fact that the court found 
reactive wastes did not contain sufficient concentrations of hazardous 
constituents to require any treatment beyond that of removing the 
characteristic. The Agency believes that it is as likely that reactive 
wastes contain underlying hazardous constituents at levels that may 
create a threat as do ignitable and corrosive wastes, and consequently, 
proposed to regulate reactive wastes in the Phase III proposal. 
Commenters submitted no data suggesting that reactive wastes do not 
contain the same types and concentrations of underlying hazardous 
constituents. Therefore, EPA is promulgating treatment standards for 
reactive wastes (other than reactive sulfides and cyanides) in this 
rule that require treatment of all underlying hazardous constituents 
reasonably expected to be present in the reactive wastes at the point 
of generation.
    EPA is, however, temporarily deferring application of these amended 
LDR treatment standards for reactive wastes with respect to unexploded 
ordnance and other explosive devices which are the subject of an 
emergency response. An emergency response is an action taken to prevent 
imminent risk of explosion. (See 40 CFR 264.1(g)(8)

[[Page 15569]]
setting out circumstances where such responses are exempt from RCRA 
permitting requirements.) During the development of the proposed 
Military Munitions Rule: Hazardous Waste Identification and Management; 
Explosives Emergencies; Redefinition of On-site proposed rule (60 FR 
56468, November 8, 1995), the Department of Defense, the military 
services, and other Federal agencies raised concerns that LDR 
requirements requiring treatment of underlying hazardous constituents 
might impede the most effective emergency responses involving these 
materials. If a responding team had to determine LDR applicability 
before deactivating an explosive subject to an emergency response, the 
response could be significantly delayed or complicated. Furthermore, 
concern about LDR applicability might discourage the team from 
responding at all. This discussion serves as EPA's initial response to 
these comments.
    EPA agrees that the primary goal in emergency responses to 
explosives is the safe and prompt elimination of immediate threats to 
human life and property, and the Agency would be concerned if LDR or 
other regulatory requirements complicated these responses. The issue is 
too important and potentially complicated to resolve in today's rule. 
Therefore, EPA is temporarily deferring final action while it considers 
this issue further.
    In deferring action for this limited class of reactive wastes, EPA 
notes that emergency responses present issues different from routine 
management of reactive wastes, where there is no competing 
consideration of need for immediate action to prevent an imminent 
threat. In non-emergency response management situations, as discussed 
earlier, the Agency believes these wastes can be fully treated to 
minimize both short and long-term threats posed by land disposal of 
wastes.1 EPA also is amending the treatment standards for wastes 
exhibiting the toxicity characteristic to include standards for 
underlying hazardous constituents.

    \1\ EPA also notes that it is not reopening the issue of open 
burning/open detonation of reactive wastes. In 1986, EPA determined 
that such activities are not a form of land disposal. See 51 FR at 
40580 (Nov. 7, 1986).
---------------------------------------------------------------------------

    Toxic wastes can also contain underlying hazardous constituents in 
the same potentially harmful concentrations as ICR wastes. 60 FR at 
11706. Today's final rule consequently conforms standards for toxic 
characteristic hazardous wastes to assure treatment of underlying 
hazardous constituents as well, when such constituents are present at 
levels exceeding the minimize threat level (as established either by 
the current technology-based standards or, if risk-based levels are 
established, exceeding a risk-based level.) Thus, the prohibitions and 
standards in today's rule will apply to ignitable, corrosive, reactive 
and toxic characteristic wastes, as just discussed.

II. Miscellaneous Issues for Which EPA Is Not Finalizing an Approach in 
This Final Rule

A. Treatment Standards for Organobromine Wastes

    Organobromine wastes are not yet listed as hazardous. EPA 
anticipates making a final listing determination in a future 
rulemaking.
    Although EPA proposed treatment standards for organobromine wastes, 
it clearly would be putting the cart before the horse to promulgate 
treatment standards in advance of a determination of whether the wastes 
are hazardous. The Agency intends to establish treatment standards for 
organobromine wastes should these wastes are listed in the future.

B. Potential Prohibition of Nonamenable Wastes From Land-Based 
Biological Treatment Systems

    The proposed rule contained an extensive discussion of whether 
certain wastes should be prohibited from placement in biological 
treatment surface impoundments because they are not amenable to 
biological treatment. To allow more time to gather comments, the Agency 
has decided to address this issue in the LDR Phase IV rule, which was 
proposed on August 22, 1995 (60 FR 43654) and is scheduled to be 
finalized in June of 1996.

C. Certain Sections of Completing Universal Treatment Standards

    The LDR Phase III proposed rule included a section on the 
completion of universal treatment standards (60 FR at 11727, March 2, 
1995). Possible nonwastewater universal treatment standards (UTS) for 
eleven constituents were discussed in the proposal, and comments and 
data were solicited. In general, commenters felt more data should be 
gathered before EPA proposes nonwastewater standards for these 
constituents, and EPA agrees. EPA had also solicited comment and data 
on extending certain universal treatment standards to fill gaps in the 
Sec. 268.40 table of universal treatment standards where ``NA'' 
appeared for either the wastewater or nonwastewater form of a regulated 
hazardous constituent. Commenters were opposed to this, stating that it 
would be arbitrary to add a standard to a waste code where before there 
was none without supporting data. The Agency again agrees. Therefore, 
EPA is not taking final action at this time.

D. Prohibition of Hazardous Waste as Fill Material

    EPA proposed to prohibit use of hazardous waste as fill material. 
60 FR at 11732. Because issues raised in the proposal are related to 
those in a number of other pending rulemakings, including the Hazardous 
Waste Identification Rule, and the proposed rule relating to land-based 
uses of hazardous waste K061 (59 FR 67256 (Dec. 29, 1994)), EPA is not 
taking final action on the proposal at this time.

E. Point of Generation

    The Agency discussed possible changes that could be made to the 
``point of generation''--or point at which LDR requirements attach to a 
hazardous waste (see 60 FR 11717, March 2, 1995). The Agency is still 
considering the options discussed in the proposal and potentially other 
options not discussed. The Agency will reopen the point of generation 
issue for further comment, and is intending to finalize an option in a 
future rulemaking.

F. Prohibition on Using Iron Filings to Stabilize Spent Foundry Sand

    The Agency proposed designating the practice of adding iron dust/
filings to spent foundry sand as impermissible dilution (60 FR 11731, 
March 2, 1995). The Agency is gathering data on the stability of the 
chemical bond formed between the iron and lead in the spent foundry 
sand. After the Agency analyzes these data, as well as further studies 
the public comments on this issue, it may take final action on the 
proposal.

III. End-of-Pipe Equivalence: Treatment Standards for Clean Water Act 
(CWA) and CWA-Equivalent Wastewater Treatment Systems

A. Types of Facilities to Which Treatment Standards Apply

    As explained above, the D.C. Circuit established a standard of so-
called end-of-pipe equivalence, allowing CWA treatment systems with 
surface impoundments to dilute characteristic wastes before land 
disposal in those impoundments without violating LDR requirements, 
provided the treatment system destroys, immobilizes, or removes an 
equivalent amount of hazardous constituent as if the characteristic 
waste were treated separately to meet RCRA standards. EPA

[[Page 15570]]
is establishing in this rule the treatment standards that must be 
satisfied in order to demonstrate that equivalent treatment is 
occurring.
    These treatment standards apply to the following types of 
facilities: (1) facilities treating formerly characteristic wastes in 
surface impoundments whose ultimate discharge is subject to regulation 
under either section 402 or 307 of the CWA. The rule thus encompasses 
both direct dischargers (facilities discharging to navigable waters) 
and indirect dischargers (those discharging to POTWs); and, (2) 
permitted and unpermitted zero dischargers engaging in treatment that 
is equivalent to that of the CWA-regulated facilities (see 40 CFR 
268.37(a) defining CWA-equivalent treatment), including facilities 
treating formerly characteristic wastes in tanks prior to release on 
the land for such purposes as irrigation or land treatment.
    EPA also wishes to make clear the types of wastewater management 
situations to which these standards do not apply. First, the standards 
do not apply to facilities that discharge to navigable waters or POTWs 
and that manage decharacterized wastes in treatment systems without 
surface impoundments. Consequently, if a facility generates a 
characteristic waste, dilutes it so that it no longer exhibits a 
characteristic, and then treats the waste in tanks before ultimate 
discharge to a navigable water or a POTW, this rule does not apply. 
There is no land disposal of a prohibited waste occurring and 
consequently no RCRA requirement that the characteristic waste be 
pretreated. Applicable CWA limitations and standards would, of course, 
continue to apply (as would a one-time recordkeeping requirement under 
RCRA (see Sec. 268.9).
    Second, the standards do not apply in situations where RCRA 
hazardous waste (subtitle C) impoundments are used. The statute already 
sets out the requirements for subtitle C impoundments receiving wastes 
which may not yet have met a treatment standard. RCRA section 
3005(j)(11). These requirements are not altered by the Third Third 
opinion. 976 F. 2d at 24 n. 10.
    Finally, in response to comment, EPA has determined that the end-
of-pipe treatment standards should not apply to stormwater 
impoundments. Stormwater impoundments are used by treatment facilities 
to catch stormwater during rain events, because their biological 
treatment systems cannot adequately handle such sudden, large volumes 
of water. At some treatment facilities, however, because they have a 
combined wastewater system, stormwater impoundments also receive 
process water containing decharacterized wastes.
    The Agency agrees with commenters who stated that stormwater 
impoundments are necessary to maintain the efficacy of biological 
treatment units. In addition, such impoundments are empty most of the 
time because they are designed for emergency rain events. In the Third 
Third opinion, the court focused on wastewater treatment surface 
impoundments. It seems likely that stormwater impoundments were outside 
the court's consideration. Furthermore, imposing treatment standards on 
such impoundments could require treatment of the stormwater/
decharacterized waste before it could permissibly go into the 
impoundment, not a practical alternative during a major storm event. 
Alternatively, imposing LDR treatment standards might require the 
facility to replace its combined wastewater system, which would be a 
major disruption to most of these facilities and hardly seems justified 
when stormwater impoundments are used only on an emergency basis. These 
are the very types of disruptions that the integration clause in RCRA 
1006(b) is intended to prevent. Consequently, EPA is indicating that 
today's rule does not apply to stormwater impoundments.

B. End-of-Pipe Treatment Standards

    The treatment standards that EPA is promulgating for characteristic 
wastewaters are found in the table of LDR treatment standards at 40 CFR 
268.40 and 268.48. As explained more fully in the following section, 
these treatment standards generally adopt the limitations or standards 
that apply to the facility's discharge as the RCRA treatment standards. 
The reason EPA is taking this approach is that the CWA industry 
category or case-by-case industrial POTW limitations and standards 
represent specific determinations of what Best Available Treatment 
(BAT) technology is capable of achieving for that plant's wastewater, 
or, in the case of Water Quality Criteria-based limitations, what an 
appropriate limit is based on BAT treatment plus risk-based 
considerations. In the event a hazardous constituent present in the 
wastewater at point of generation of the original characteristic 
hazardous waste is not already regulated pursuant to a CWA limitation 
or standard, the RCRA Universal Treatment Standard for that constituent 
would apply.
    These treatment standards may be met at the CWA point of 
compliance, typically the point the wastewater is discharged to a 
navigable water or a POTW. For CWA-equivalent facilities, the treatment 
standards must be met at the point where the wastewater is sprayed onto 
the land in irrigation (or similar) activities, or injected into a non-
Class I injection well. This accords with the equivalence standard 
established by the court: ``hazardous constituents are [to be] removed 
from the waste before it enters the environment.'' 976 F. 2d at 24; see 
also id. at 23 and n. 8. Most commenters likewise agreed with an end-
of-pipe measuring point. Indeed, requiring full treatment before 
ultimate discharge could destroy the very accommodation with the CWA 
regime that the court thought critical. See 60 FR at 13677 (Aug. 22, 
1995).
    However, EPA also agrees with commenters that there is no reason to 
impede individual facilities from choosing an alternative point of 
compliance (i.e. other than end-of-pipe) provided the facility can 
demonstrate that the prohibited waste (the decharacterized portion of 
the combined effluent) has been treated by means other than dilution to 
remove an equivalent mass of hazardous constituents. This is 
specifically consistent with the principle announced in the 
Administration's report on ``Reinventing Environmental Regulation'' to 
``provid[e] maximum flexibility in the means of achieving our 
environmental goals, but requiring accountability for the results''. 
Consequently, the Agency is allowing a facility to designate any 
compliance point downstream of treatment that destroys, immobilizes, or 
removes hazardous constituents as the point for demonstrating that 
equivalent treatment occurs. This point can, but need not be, the NPDES 
or pretreatment point of compliance. Examples of alternative points of 
compliance that would be permissible (assuming the treatment standard 
is being satisfied) would be prior to initial placement in an 
impoundment, or after treatment in an impoundment but before final 
discharge.
    The Agency also agrees with commenters that there can be 
alternative points of compliance for different underlying hazardous 
constituents. Again, the reason is to allow flexibility of compliance 
alternatives when a facility can demonstrate that it is destroying, 
immobilizing, or removing an equivalent mass of hazardous constituents 
through wastewater treatment as would be achieved by segregating the 
characteristic wastestream for separate RCRA treatment. Thus, if a 
facility generated a

[[Page 15571]]
characteristic waste containing metal and organic underlying hazardous 
constituents and the waste was treated sequentially by means not 
involving impermissible dilution, there could be different compliance 
points for the metal and organic hazardous constituents.
    EPA notes, however, that if alternative points of compliance are 
utilized, enforcement would normally be pursuant to RCRA, not the Clean 
Water Act. This is by necessity, since CWA permits (or, for indirect 
dischargers, control mechanisms) would not normally apply to effluent 
quality before final discharge. See further discussion on means of 
implementing today's standards below in this preamble.

C. Why CWA Limitations and Standards Can Also Be RCRA Treatment 
Standards

    As explained above, when a hazardous constituent is already subject 
to a CWA industry category or Water Quality Criteria-based limitation, 
or a case-by-case industrial POTW limitation or standard, the Agency 
believes (and the final rule provides) that the CWA limitations and 
standards satisfy RCRA section 3004(m) requirements and consequently 
become the RCRA treatment standard for purposes of demonstrating 
equivalent treatment. EPA believes that this is an obvious and 
effective means of integrating CWA and RCRA requirements, in accord 
with the court's objective. 976 F. 2d at 22; RCRA section 1006(b). This 
approach was generally supported by commenters as a reasonable means of 
satisfying the court's mandate and the underlying policy of integration 
of the two statutes.
    Several commenters, however, argued that CWA limitations and 
standards could not be equivalent to RCRA because such standards can 
reflect (among other things) ``the cost of achieving such effluent 
reduction'', and ``the age of equipment and facilities involved''. CWA 
section 304(b)(2)(B) (factors to be considered in determining Best 
Available Technology). EPA disagrees. While it is true that technology-
based standards developed to address toxic pollutants from various 
industrial categories are developed after consideration of levels that 
can be achieved through application of the best available technology 
economically achievable, the CWA limitations and standards nevertheless 
represent the best evaluation of what technically advanced wastewater 
treatment is capable of achieving for a particular industry's (or, in 
some cases, particular plant's) wastewater. Although there is no 
requirement that a particular treatment technology must be used to 
achieve the facility's limits, it is expected that plants utilizing BAT 
will have treated their effluent so that there are substantial 
reductions in concentration and mass of hazardous constituents. As the 
Agency has stated many times, EPA believes that section 3004(m) is 
satisfied by treatment that substantially destroys, immobilizes, and 
removes the hazardous constituents that are present in the waste, 
notwithstanding that minor amounts of hazardous constituents remain 
after treatment. Put another way, the statute does not require that 
every conceivable threat posed by land disposal be eliminated by 
treatment. 55 FR at 6641 and n. 1 (Feb. 26, 1990); 56 FR at 12355 
(March 25, 1991); 57 FR 37259 (August 18, 1992); 55 FR at 22596 (June 
1, 1990). In fact, the legislative history states explicitly that the 
treatment standards are not to be technology forcing, but rather are to 
utilize the available effective treatment technologies. 130 Cong. Rec. 
S. 1978 (daily ed. July 25, 1984) (statement of Sen. Chaffee); 56 FR at 
12355. That is precisely what EPA has done here.
    Second, with specific regard to use of CWA limitations, EPA notes 
that virtually all of the current LDR treatment standards for 
wastewaters are already drawn from CWA limitations and standards. See 
55 FR at 22601 (wastewater standards for U and P wastes and F039, which 
essentially became the universal treatment standards, were transferred 
from treatment data from CWA programs), and see also the Final BDAT 
Background Document for U and P Wastes and Multi-Source Leachate (F039) 
Volume C (documenting that most of existing RCRA wastewater standards 
were transferred from CWA limitations and standards). Moreover, the 
technologies that are often used to achieve CWA limitations and 
standards are, in most cases, the same technologies upon which the RCRA 
Universal Treatment Standards are based. As EPA has already stated, 
``because most treatment technologies cannot be so precisely calibrated 
as to achieve, for example, 3.5 ppm rather than 2.7 ppm, the likely 
result is that the same amount of treatment will occur.'' 59 FR at 
47989 (Sept. 19, 1994). Since frequently the same technologies are used 
to treat wastewaters, EPA expects the degree of treatment to be 
comparable.
    EPA also emphasizes that RCRA section 1006(b) requires EPA (among 
other things) to integrate provisions of RCRA and the CWA when 
implementing RCRA, and to avoid duplication to the maximum extent 
possible with CWA requirements. The Agency feels it is accomplishing 
this requirement by allowing a constituent-specific, CWA treatment 
standard to satisfy RCRA 3004(m). The Agency reiterates that a 
technology-based CWA limitation or standard for a hazardous constituent 
satisfies RCRA because such a limitation or standard directly reflects 
the capability of BAT technologies to treat a specific industry's or 
facility's wastewater, whereas the RCRA UTS for wastewaters were 
developed by transferring performance data from various industries, and 
thus EPA need not make that same transfer when industry-specific (or 
plant-specific) wastewater treatment data is available.
    A water-quality based limitation would also satisfy RCRA section 
3004(m). A CWA water quality-based limitation must be at least as 
stringent as the limitations required to implement an existing 
technology-based standard. (See CWA section 301(b)(1)(c).) Even where 
there is no existing BAT limitation for a toxic or nonconventional 
pollutant, a permit writer must determine whether BAT would be more 
stringent than the applicable water quality-based limitation, and 
again, must apply the more stringent of the two potential limitations. 
(40 CFR 125.3(c)(2).)
    If a facility has received a Fundamentally Different Factors (FDF) 
variance, the limitations established by that variance also satisfy 
RCRA requirements. Limitations established by the FDF variance process 
are technology-based standards reflecting facility-specific 
circumstances, and hence can appropriately be viewed as BDAT as well, 
just as with RCRA treatability variance standards. See 51 FR at 40605 
(Nov. 7, 1986).
    EPA also believes that there are adequate constraints in the CWA 
implementing rules to prevent these end-of-pipe standards from being 
achieved by means of simple dilution. First, many of the effluent 
limitation guidelines and standards regulate the mass of pollutants 
discharged, and thus directly regulate not only the concentration of 
pollutant discharged but the degree of wastewater flow as well. Even 
where rules are concentration-based, NPDES permit writers can set 
requirements which preclude excessive water use, and EPA has so 
instructed permit writers. (See 58 FR 66151, December 17, 1993, 
encouraging permit writers to estimate reasonable rate of flow per 
facility and factor that flow limit into the permit.) These permit 
conditions can take the form of best management practices,

[[Page 15572]]
explicit mass limitations, and conditions on internal waste streams. 40 
CFR 122.44(k); 122.45 (f), (g) and (h).
    Indirect dischargers are also subject to specific CWA dilution 
rules in both the general pretreatment rules and the Combined 
Wastestream Formula (as well as through many of the categorical 
standards). 40 CFR 403.6 (d) and (e). Many of the guidelines and 
standards also preclude addition of stormwater runoff to process 
wastewater to preclude achieving treatment requirements by means of 
dilution. The Agency is accordingly of the view that end-of-pipe 
equivalence would be achieved by treatment that removes, immobilizes, 
or destroys hazardous constituents, and therefore we have determined 
the treatment satisfies the requirements of RCRA section 3004(m).
    EPA emphasizes, however, that it is not addressing the issue of 
whether cross-media transfers of hazardous constituents become so 
extensive as to invalidate the wastewater treatment function of a land-
based unit. This is the subject of the pending Phase IV proposed rule 
(60 FR at 43654 (August 22, 1995)), and will be addressed as part of 
that proceeding.

D. When CWA Limitations and Standards Become the RCRA Standards

    Today's rule establishes the following principles:
1. Direct Dischargers
    A CWA limitation becomes the RCRA treatment standard as well in the 
following situations: (a) where there is a categorical BAT or NSPS 
limitation for the underlying hazardous constituent; (b) where there is 
a facility-specific limitation for the underlying hazardous constituent 
pursuant to 40 CFR 125.3 (c)(2) and (d)(3); (c) where there is a Water 
Quality-based limitation established pursuant to 40 CFR 122.44(d); or 
(d) where the facility has received a Fundamentally Different Factors 
variance establishing an alternative limitation pursuant to 40 CFR Part 
125 subpart D.
2. Indirect Dischargers
    A Clean Water Act pretreatment standard becomes the RCRA treatment 
standard as well in the following circumstances: (a) where there is a 
categorical PSES or PSNS for a particular hazardous constituent; and, 
(b) where POTWs have developed local limits, in addition to categorical 
standards, to prevent pass through and interference and apply them to 
indirect dischargers.
    EPA proposed that if pretreatment standards reflected a finding 
that a particular hazardous constituent will not pass through to 
navigable waters because of efficacious treatment by the POTW, that 
standard would also satisfy RCRA. The reason is that there will be 
full-scale treatment of the hazardous constituent before its final 
release into the environment. Such full-scale treatment satisfies the 
court's equivalency test. 60 FR at 11711. EPA is adopting this 
provision in today's rule for these reasons.
    The Agency also proposed that pretreatment standards based on 
interference with POTW operations would not be considered to satisfy 
RCRA. Id. EPA is adopting this position in the final rule. The reason 
is that interference findings reflect the effect the pollutant may have 
on overall POTW treatment, not necessarily treatment of the particular 
constituent. Because the relationship of an interference-based standard 
with treatment of a particular hazardous constituent is tenuous, EPA 
does not believe that such a standard can be said to be equivalent to 
RCRA treatment. Several commenters disagreed with this reasoning, but 
provided no empirical information calling the Agency's conclusion into 
question. EPA is consequently adopting this provision as proposed.
3. Zero Dischargers Performing CWA-Equivalent Treatment
    In the May 24, 1993 emergency rule, EPA established the principle 
that zero discharge facilities performing CWA-equivalent treatment on 
decharacterized wastewaters would be subject to the rules for direct 
dischargers, and thus would retain the ability to use surface 
impoundments as part of the treatment process for decharacterized 
wastes provided equivalent treatment occurs. 58 FR at 29863-29864. The 
reason is that these facilities can be performing wastewater treatment 
identical to, or more stringent than, that required of direct 
dischargers, and thus the same policy of integrating RCRA and the CWA 
should apply to such facilities. Id. 
    EPA is consequently also applying today's rules on equivalency to 
zero dischargers performing CWA-equivalent treatment, including tank-
based systems that ultimately land dispose rather than discharge 
treated effluent. ``CWA-equivalent treatment'' is defined in 268.37(a) 
to mean ``biological treatment for organics, alkaline chlorination or 
ferrous sulfate precipitation/sedimentation for metals, reduction of 
hexavalent chromium, or other treatment technology that can be 
demonstrated to perform equally or greater than these technologies''.

E. Implementation

1. Where Permits Contain Standards for Hazardous Constituents
    If a direct discharger subject to the rule (i.e. generating a 
characteristic waste containing underlying hazardous constituents at 
concentrations exceeding the treatment standard at the point the waste 
is generated, and is treating those decharacterized wastes in surface 
impoundments) has an NPDES permit containing a limitation for that 
hazardous constituent based on BAT, NSPS, BPJ, or a water quality 
standard, then there are no independent RCRA requirements beyond 
documenting in the facility's records that this is the facility's mode 
of compliance.
    EPA notes further that if the Agency (or authorized State), as part 
of the CWA decisionmaking process for setting the limitations, 
affirmatively decided that such hazardous constituents need not be 
regulated due to low toxicity, low bioavailability or other 
environmental factors and that fact is reflected in the rulemaking 
record, permit or permit record, no additional RCRA standards would 
apply. If the rulemaking or permit and permit record do not contain 
such a finding, the permitting authority should reexamine the NPDES 
permit upon reissuance in order to clarify whether such hazardous 
constituents need not be regulated. During the time between the date 
this rule becomes effective and the date the permit is reissued, 
however, the RCRA Universal Treatment Standards for those constituents 
must be met.
    In addition, if EPA (or an authorized State) affirmatively decided 
either in the rulemaking or in the permitting process that a particular 
hazardous constituent is controlled through controls on an indicator 
pollutant, then again, no additional RCRA standards would apply. For 
this purpose, however, the Agency would only accept as a valid 
indicator situations where a toxic pollutant parameter is used as an 
indicator for another toxic pollutant. The Agency does not believe that 
use of conventional pollutants (such as BOD or COD) as indicators for 
toxic constituents guarantees the type of equivalent treatment of 
hazardous constituents, which EPA feels is necessary to implement the 
equivalence requirement. 976 F. 2d at 23 n. 8.2

    \2\ In making this statement, EPA is of course not calling into 
question the use of conventional pollutants as valid indicators to 
satisfy Clean Water Act requirements. The language in the text is 
directed solely at implementing the court's mandate for purposes of 
RCRA.

[[Page 15573]]

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

2. Where Permits Do Not Contain a Limitation for a Hazardous 
Constituent
    If the CWA permit either does not contain a limitation for the 
pollutant or does not regulate the pollutant through an indicator, or 
in cases when this rule becomes effective before the reissuance of a 
facility's permit, the RCRA universal treatment standards would apply 
as they do for any other RCRA hazardous wastestream. In this situation, 
the owner or operator of a facility has several choices. The owner/
operator could do nothing, in which case the hazardous constituent 
would be subject to the UTS. These standards would be implemented by 
rule, and thus would not be embodied in a CWA permit. Enforcement 
consequently would be solely under RCRA. As noted earlier, the point of 
compliance could, but need not be, at the end-of-pipe point of 
discharge.
    In the alternative, a facility could seek amendment of its NPDES 
permit pursuant to Sec. 122.62(a)(3), requesting that the applicable 
permitting authority modify the permit at reissuance, or sooner, to add 
limits for the underlying hazardous constituents reflecting BAT for 
that pollutant at the facility.\3\ Assuming proper design and operation 
of the wastewater treatment technology, a permit writer in such a case 
could modify the permit to add a limitation for the pollutant based on 
Best Professional Judgement reflecting actual BAT treatment (40 CFR 
125.3(c)). Modification requests would be processed pursuant to the 
procedures found at Sec. 124.5. The modified permit limitation would be 
a CWA requirement and enforceable solely under that statute, but would 
be deemed by the Agency to satisfy RCRA 3004(m), so that meeting UTS 
per se would not be required.

    \3\ EPA is interpreting the language in Sec. 122.62(a)(2) to 
indicate that the D.C. Circuit's opinion in the Third Third case is 
new information warranting reopening a permit.
---------------------------------------------------------------------------

    A final alternative is for the facility to seek a RCRA treatability 
variance. EPA is amending the grounds for granting such a variance to 
include situations where a facility is treating decharacterized wastes 
by treatment identified as BAT or NSPS (New Source Performance 
Standards), the technology is designed and operated properly, but is 
not achieving the UTS (see Sec. 268.44(a)).
3. Indirect Dischargers
    The same alternatives exist for indirect dischargers. If an 
underlying hazardous constituent is regulated by a categorical PSES, 
PSNS, or by a local limit in a control mechanism reflecting PSES or 
PSNS--level treatment, then that standard satisfies both RCRA and the 
CWA. In addition, if there is no pretreatment standard (i.e., PSES/
PSNS) for an underlying hazardous constituent, because the Agency 
determined that there was no pass through, then section 3004(m) is 
satisfied and the RCRA standard for that underlying hazardous 
constituents does not apply.
    If an underlying hazardous constituent is not regulated nationally 
by a PSES or PSNS, or by a local limit, it becomes subject to the UTS 
for that constituent. That UTS would be enforced as a RCRA standard. 
However, in cases where an underlying hazardous constituent is not 
already subject to categorical PSES, categorical PSNS, or to a local 
limit in a control mechanism reflecting PSES or PSNS-level treatment, 
water quality, or pass through, the control mechanism between the 
indirect discharger and the applicable control authority would have to 
be modified in order to avoid application of the UTS by rule. EPA is 
amending Sec. 403.5(c)(1) and Sec. 403.5(c)(2) of the pretreatment 
rules to specifically authorize control authorities to make such 
determinations.
    The final option is for a facility to obtain a RCRA treatability 
variance. Thus, the amendment to the treatability variance rules also 
applies to indirect dischargers properly operating technology 
identified as the basis for their PSES or their PSNS standard.
4. Zero Dischargers Performing CWA-Equivalent Treatment
    The implementation options for zero dischargers performing CWA-
equivalent treatment are similar. Some of these facilities may have CWA 
permits authorizing specified levels of discharge. If these permit 
limitations apply to underlying hazardous constituents present in the 
RCRA-prohibited portion of the discharge, the CWA permit limit 
satisfies RCRA as well. The facility also could seek to amend the CWA 
permit to add limitations for the hazardous constituent. Enforcement 
then would be exclusively pursuant to the CWA.
    If the zero discharger has no CWA permit, or the permit does not 
contain limitations for underlying hazardous constituents and is not 
amended to do so, then the facility would have to meet the RCRA UTS or 
an alternative standard established by treatability variance either at 
the point of discharge 4 or at an earlier point of its choosing 
(assuming, of course, that a valid demonstration of bona fide treatment 
can be made at an earlier point).

    \4\ The point of compliance for a zero discharger choosing the 
point of discharge as a compliance point would be at the point of 
ultimate disposal. For those zero dischargers who discharge to a dry 
river bed (common in the western U.S.) not considered a ``water of 
the U.S.'' under the CWA, the point of compliance would be at the 
end-of-pipe. For those zero dischargers who spray irrigate, or 
otherwise place the wastewaters on the land after treatment in the 
surface impoundment, the point of compliance would be at the point 
just prior to the land placement. Furthermore, zero dischargers 
treating wastewaters in a tank system followed by spray irrigation 
or another form of land placement are also subject to this rule. For 
those zero dischargers who use evaporation ponds, the point of 
compliance is before the wastewater enters the surface impoundment, 
as this is the ultimate disposal point.
---------------------------------------------------------------------------

5. Implementation When CWA Standards and Limitations Will Not Be the 
Exclusive Standard
    If the facility treats to UTS and does not modify its CWA permit or 
control mechanism to include a CWA standard/limitation for an 
underlying hazardous constituent, EPA is finalizing minimal 
recordkeeping requirements, under RCRA authority. Generators can use 
their knowledge to identify the underlying hazardous constituents 
reasonably expected to be present at the point of generation of the 
ICRT wastes which are not covered by a CWA limitation or standard and 
hence must be treated to meet UTS (assuming no permit modification). 
EPA is requiring that this information be kept on-site in files at the 
facility. The facility will then monitor compliance with the UTS 
standard for each of these constituents at the point of ultimate 
discharge or alternative compliance point, on a quarterly basis, and 
results of this monitoring must be kept in the facility's on-site 
files. An exceedence of the RCRA UTS standard must be documented in the 
facility's on site records.
    These same requirements apply to facilities without NPDES permits 
documenting compliance as zero dischargers with CWA-equivalent 
treatment who are affected by this rule. The absence of a permit 
necessitates some alternative means of documenting compliance, and the 
scheme outlined above seems to be the least burdensome scheme which 
would still provide a reasonable means of enforcing this rule.
6. RCRA Controls Over Point Source Discharges and Domestic Sewage
    Both RCRA and the implementing regulations provide that point 
source discharges and domestic sewage (including mixtures of domestic 
sewage with other wastes) are not subject to

[[Page 15574]]
RCRA subtitle C jurisdiction. RCRA section 1004(27) and Sec. 261.4(a) 
(1) and (2). Some commenters questioned whether by allowing CWA 
limitations and standards to satisfy the RCRA treatment standard 
requirement, EPA were somehow imposing RCRA controls where it lacks 
authority to do so.
    This is not the case. EPA is creating here a mechanism for 
evaluating whether RCRA-equivalent treatment has occurred for purposes 
of determining whether surface impoundments (i.e. RCRA land disposal 
units) can permissibly be used as part of that treatment process. 976 
F. 2d at 22-24. The effect, for RCRA purposes, of failing to satisfy 
the limitations or standards is that the facility has engaged in 
illegal land disposal by virtue of not performing equivalent treatment. 
Id. Thus, the effect of the rule is on activity upstream of the 
discharge point, and these activities are within RCRA's jurisdictional 
purview.
7. Applicability to the Pulp and Paper Industry
    The concerns about integration of CWA and RCRA standards are 
particularly acute with respect to the pulp and paper industry. EPA is 
at a critical stage in developing comprehensive multi-media rules for 
this industry (to control both hazardous air emissions and wastewater 
discharges). These rules were proposed at 58 FR 66078 (Dec. 17, 1993) 
and are slated for promulgation by mid-1996. The rules should 
fundamentally affect (for the better) the types of wastewaters managed 
at pulp and paper facilities and the potential releases of hazardous 
constituents from such wastes. The Agency believes that it would be 
putting the cart before the horse, and would fail to properly 
integrating RCRA with the CWA (and potentially CAA in this case) by 
proceeding with implementation of the court's decision for this 
industry in advance of completion of this rulemaking. Cf. Edison 
Electric Inst. v. EPA, 2 F. 3d 438, 453 (D.C. Cir. 1993) noting when 
temporary deferrals of action to allow better integration of 
overlapping statutes is permissible. The Agency will revisit the 
question of how to implement the court's decision for the pulp and 
paper industry upon completion of the existing multi-media rulemaking.

IV. Treatment Standards for Class I Nonhazardous Injection Wells and 
Response to Comments

A. Introduction

    Generally, Class I nonhazardous injection well owners/operators 
injecting decharacterized ICRT wastes do not substantially treat their 
waste beyond removing the characteristic by aggregating and diluting 
wastestreams, plus filtering of solids in order to facilitate 
injection. There are as many as 100 such nonhazardous facilities in 
addition to the approximately 54 hazardous facilities injecting ICRT 
wastes. As discussed in the Phase III proposed rule, EPA estimates that 
the average flow of a ``typical'' Class I nonhazardous well is 107,000 
gallons/day. Typically, the volume of hazardous wastes comprises 25% or 
less of the aggregated injected wastestream.
    In the Third rule, EPA proposed that characteristic wastes were not 
prohibited from injection into these deep wells provided they no longer 
exhibited a characteristic at the point they are injected.e. land 
disposed. 60 JR at 11704-11705. The D.C. Circuit rejected this portion 
of the rule, holding, in EPA's reading of the opinion, that the 
statutory requirements could not be satisfied absent treatment that 
addressed both short term and long term threats posed by land disposal 
of the waste, and hence that hazardous constituents in the waste had to 
be destroyed, removed or immobilized before injection, not merely 
diluted. 60 JR at 11706-11708. EPA is implementing that mandate in this 
rule. (However, EPA reiterates, as it did at proposal, that EPA is 
taking this action to implement the court's mandate, not because it is 
an environmental priority, or prudent use of the Agency's or the 
regulated community's resources. The Administration is in fact pursuing 
a legislative change which would restore EPA's original policy 
determination reflected in the 1990 Third rule.)
    The effect of today's final rule is to prohibit the land disposal 
of characteristic waste streams at the point they are generated. If 
those wastes contain underlying hazardous constituents at levels 
exceeding the Universal Treatment Standards and (as explained further 
below) at levels and volumes greater than designated de minims amounts, 
those constituents would have to be destroyed, removed, or immobilized 
before the waste is injected. This could be accomplished either by 
segregating the characteristic portion of the injectate for treatment, 
or by treating the commingled injectate before disposal (i.e. before 
injection). The rule further provides that if a facility removes an 
equivalent mass of the hazardous constituent through source reduction, 
or waste treatment, that the treatment standard is satisfied. The 
final, alternative means of compliance is for the unit to have received 
a no-migration determination.
    A number of commenters believed that aggregation or dilution of 
wastes to remove the hazardous characteristic of the waste stream prior 
to injection was sufficient and that the requirement to treat 
underlying constituents was legally unnecessary and onerous. EPA's 
reading of the Third Third opinion and section 3004(m) is that 
treatment that destroys, immobilizes, or removes hazardous constituents 
is required, and that this requirement is not satisfied merely by 
dilution. The statutory findings of the inherent uncertainty of land 
disposal of hazardous wastes, the propensity to bioaccumulate these 
same constituents, the statutory goals of waste minimization and proper 
waste management, plus the legislative history documenting 
Congressional intent not to permit treatment by dilution supports the 
Agency in rejecting these comments. 60 FR at 11706-708. Therefore, the 
Agency has decided not to allow Class I nonhazardous wells to dilute or 
aggregate their waste streams in order to fulfill, substitute, or avoid 
treatment levels or methods established in the LDRs. See the dilution 
prohibition added in Sec. 148.3 of today's final rule.
    Furthermore, the Agency, as proposed, is expanding the 
applicability of 40 CFR Part 148 to now require owners/operators of 
Class I nonhazardous wells to determine whether LDRs apply to their 
facilities.
    Commenters likewise sharply questioned the Agency's determinations 
as to when land disposal prohibitions should attach, and state, 
correctly in the Agency's view, that the opinion did not compel a 
determination that prohibitions must attach at the initial point of 
waste generation or when underlying hazardous constituents are present 
at that point in concentrations exceeding the UTS. EPA is in fact 
pursuing alternatives on both of these fronts. The Agency proposed 
alternatives to the strictest point of generation approach, 60 FR at 
11715-716, and expects to take final action on this proposal well 
before the effective date of the Phase III prohibitions for Class I 
non-hazardous UIC wells. The source reduction compliance option in this 
rule is a related means of dealing with this issue, since it can be 
conceptualized as allowing the requisite hazardous constituent 
reductions to be achieved by means other than downstream treatment 
notwithstanding presence of hazardous constituents above UTS at what is 
technically point of waste generation.
    With regard to whether presence of hazardous constituents above UTS

[[Page 15575]]
would be the trigger level for the LDR prohibition, EPA has recently 
proposed risk-based hazardous constituent concentration levels which 
would implement the ``minimize threat'' requirement in section 3004(m), 
and would cap the technology-based treatment standards whenever the 
technology-based standards are lower (60 FR 66344, December 21, 1995). 
The de minimis feature of today's rule further addresses situations 
where EPA believes that prohibitions need not apply due to the low 
concentrations and volumes of hazardous constituents in the 
decharacterized portion of the injectate.

B. Compliance Options for Class I Nonhazardous Wells

    In the proposed rule, the Agency indicated that facilities could 
segregate their hazardous wastes, and treat just that volume of the 
total waste stream to UTS levels in order to conform to the treatment 
requirement. A number of commenters maintained that the Agency 
oversimplified this approach and that such segregation was impractical 
from both a technical and economic standpoint. EPA acknowledges that 
many facilities may not practically be able to segregate streams. These 
facilities may utilize of other LDR compliance options as discussed 
below.
    One option would be to apply for an exemption from treatment 
standards via the no-migration petition variance. EPA is promulgating a 
clarifying revision to 40 CFR 148.20 which allows facilities to seek a 
no-migration variance for their Class I nonhazardous wells, and has 
long indicated that this compliance option is available (see pp. 25-27, 
Supplemental Information Report prepared for the Notice of Data 
Availability, January 19, 1993, 58 FR 4972). If these facilities 
demonstrate to EPA that their formerly characteristic wastes (including 
any hazardous constituents) will not migrate out of the injection zone 
for 10,000 years, or no longer pose a threat to human health and the 
environment because the wastes are attenuated, transformed, or 
immobilized by natural processes, then they may continue to inject 
without further treatment.
    A significant number of commenters responded to the proposed rule's 
discussion on the Agency's position on granting no-migration petitions. 
Comments included that petitions were a too costly option, took too 
much time to be processed, generic petitions for Class I non-hazardous 
wells should be granted, and existing no-migration exemptions should 
not require modification to include Phase III wastes. These comments, 
among others, will be discussed in detail in the ``Response to 
Comments'' background document for this rule, but basically many had 
partial merit.
    First, although the Agency has estimated earlier that the average 
petition costs an operator $343,000, several individual petition 
reviews have far exceeded that amount. The Agency will examine the 
possibility of revising petition cost data in future LDR rules. Second, 
although a petition may take up to 3 years to process, the Agency (as 
noted above) indicated as early as 1992 (after the Third Third opinion) 
that it would begin review of Class I nonhazardous injection well no-
migration petitions if submitted (58 FR 4972, January 19, 1993). 
Although time and resource restraints on the Agency are real, the 
Agency will continue to work with affected Class I operators in order 
to facilitate the no-migration petition review process. Third, although 
EPA has established a reasonable knowledge base on the review process 
for Class I hazardous facilities, it cannot automatically infer that 
all Class I nonhazardous facilities will successfully make a no-
migration demonstration. Well site geology, hydrogeology, abandoned 
well area of review, and the specific characteristics of the injectate 
and receiving formation are site specific factors which, as a factual 
matter, must be evaluated individually in order to demonstrate ``to a 
reasonable degree of certainty'' (RCRA section 3004(g)(5)) that the no 
migration standard has been satisfied. See Supplemental Report to 
Notice of Data Availability, January 19, 1993, at 25-26 9. It must be 
remembered that not every Class I injection well applying for the 
variance has been able to make the demonstration, and that one salutary 
effect of the no migration process has been to identify certain (albeit 
a limited number of) wells that would not be capable of adequately 
containing injectate over the long term.
    EPA agrees completely with commenters, however, that wells that 
already have approved no migration exemptions are not affected by the 
Third Third opinion and thus are not affected by land disposal 
restrictions affecting decharacterized wastes. (In fact, EPA does not 
read the proposal to suggest otherwise.) Absent a change in the waste 
being injected, there is no reason to reopen no migration 
determinations that have already evaluated the entire injected waste 
stream. 57 FR at 31963 (July 20, 1992).
    EPA is also promulgating additional means for Class I nonhazardous 
facilities to comply with the LDR requirements. Revisions to 40 CFR 
148.1(c)(1) and 148.4 will allow Class I nonhazardous owners and 
operators to apply for a case-by-case extension of the capacity 
variance for up to one year (renewable for up to an additional year) in 
order to acquire or construct alternative treatment capacity. Based on 
experience, EPA believes that the availability of the case-by-case 
extension coupled with national capacity variance(s) should allow 
operators more than adequate time to acquire alternative treatment or 
complete the no-migration petition process. Two other options include 
the pollution prevention option and the de minimis volume exclusion.

C. Pollution Prevention Compliance Option

    The final rule provides an alternative means of obtaining the 
reductions in mass loadings of hazardous constituents mandated by the 
Third Third opinion. Under this alternative, mass reductions can be 
achieved by removing hazardous constituents from any of the 
wastestreams that are going to be injected, and these reductions in 
mass loadings can be accomplished by means of source reduction (i.e. 
equipment or technology modifications, process or procedure 
modifications, reformulation or redesign of products, substitution of 
raw materials, and improvements in housekeeping, maintenance, training, 
or inventory control), recycling, or conventional treatment. As an 
example, if a facility can make process changes that reduce the mass of 
cadmium by the same amount that would be removed if the prohibited 
wastestream was treated to satisfy UTS, the facility would satisfy LDR 
requirements. The facility could also remove cadmium from any of the 
streams (prohibited or non-prohibited) which are going to be injected, 
or could find a means of recycling some portion of the injectate to 
reduce injected mass loadings of cadmium. In all cases, the result 
would be that the mass loading of hazardous constituents into the 
injection unit would be reduced by the same amount as it would be 
reduced by treatment of the prohibited, characteristic portion of the 
injectate. 976 F. 2d at 23 n. 8; see also Specialty Steel Inst. v. EPA, 
27 F. 3d 642, 649 (D.C. Cir. 1994) (treatment standards that result in 
lower volume of waste to be disposed--precisely what the alternative 
standard here can achieve--are a permissible means of complying with 
RCRA section 3004 (m)).
    Commenters further requested that this alternative be available on 
a hazardous constituent by hazardous constituent basis. EPA agrees that 
this is

[[Page 15576]]
reasonable since it still results in the requisite reduction of 
hazardous constituent mass loading and provides desirable compliance 
flexibility. Of course, if the pollution prevention alternative is used 
partially, there must still be compliance by some alternative means for 
the remaining hazardous constituents subject to the prohibition.
    The Agency is not, however, adopting any type of hazardous 
constituent trading provision as part of this rule. It first is not 
clear that such a provision would satisfy the equivalency test 
enunciated by the court. In addition, given the narrow time frame 
available to the Agency to develop this rule, the Agency lacks the time 
and resources to properly evaluate the ramifications of the idea in 
this proceeding.
    As a means of implementing this alternative, EPA is adopting the 
method proposed. The mass/day reduction of a particular underlying 
hazardous constituents is to be calculated by comparing the injected 
baseline with the allowance. The injected baseline is determined by 
multiplying the volume/day of prohibited hazardous waste generated and 
subsequently injected times the concentration of hazardous constituents 
before the pollution prevention measure. The allowance is determined by 
multiplying the volume/day of a hazardous constituent generated/
injected times the UTS for that constituent. The difference between the 
injected baseline and the allowance is the required mass/day reduction.
    EPA proposed, and is adopting the requirement that after successful 
employment of a pollution prevention measure, the facility must 
demonstrate that the injected mass achieves the required mass/day 
reduction. Because the amount of an underlying hazardous constituent in 
the injectate is dependent upon the level of production, a correction 
factor for production is needed. In the example given in the proposal 
(60 FR 11714), the calculation for the injected baseline was corrected 
by a production variability factor based on volume. The Agency had 
solicited comment on whether there are production parameters other than 
volume (e.g., mass, square footage, etc.). One commenter gave a 
specific example where square footage would be a more appropriate 
parameter. Therefore, the Agency is promulgating today that any 
appropriate parameter may be used to calculate the production 
variability factor. Another commenter was concerned that in the example 
the baseline used after pollution prevention seemed to be based on the 
production rate, whereas the baseline before pollution prevention was 
not. The commenter misunderstood the purpose of the production 
variability factor. In the example the post-pollution prevention 
injectate was adjusted by the production variability factor; however, 
the example could have been reorganized such that the initial baseline 
was adjusted for production variability. It was not necessary to adjust 
both the pre- and post-pollution prevention baselines for production 
variabilty; in fact, doing so would cause the variability factor to 
cancel out.
    Several commenters were concerned that there are other factors 
besides rate of production which could cause variability in the level 
of an underlying hazardous constituent. One commenter mentioned 
variations in operation of specific source unit operations such as 
distillation and/or stripping trains feeding the injection unit. 
Another commenter stated that since they do not actually produce 
anything, they have no production rates to use, and suggested basing 
production on man-hours worked or total water consumed by a facility. 
The Agency agrees with all these suggestions. The mass/day of an 
underlying hazardous constituent after pollution prevention is based on 
the flowrate multiplied by the concentration of the constituent, and 
must be less than or equal to the calculated mass/day allowance for 
that underlying hazardous constituent. Beyond this basic formula, the 
facility can adjust for any factors which would cause a variation in 
the concentration of the underlying hazardous constituent, provided the 
variation(s) are part of a normal operating procedure.
    Under this approach, a facility would make a one-time change in 
operating practice. Because the mass loading reductions resulting from 
the practice are obtained from the time of the change forward, it 
obviously is not necessary (and neither practical or likely feasible) 
for the facility to make on-going (potentially daily) changes to 
qualify under the provision.
    A number of commenters, although supporting the Agency's proposal, 
argued that it should apply to facilities that already have implemented 
source reduction or other pollution prevention practices before the 
effective date of the rule, not just those making the change 
prospectively (as EPA proposed). Their point is that facilities that 
have already implemented source reduction, and as a result may now have 
fewer opportunities to do so, should not be on a worse footing than 
facilities who have been laxer and thus now have a wider range of 
possible means of reduction. This argument certainly has equitable 
force. At the same time, however, there has to be some objectively 
defined baseline period for the rule to be enforceable, and for there 
to be some nexus between the pollution prevention measure and the 
reduced mass loadings in current injectate. Balancing these 
considerations, the Agency is establishing 1990 as the base year for 
establishing a baseline. This was the year EPA adopted (per 
Congressional schedule) the prohibitions for characteristic hazardous 
waste and (coincidentally) the year of the Pollution Prevention Act.
    EPA is sensitive to other comments regarding the need for this 
alternative to be objectively verifiable. The Agency is therefore 
requiring that facilities must monitor the underlying hazardous 
constituent concentration and the volume of the prohibited hazardous 
waste stream (i.e. all characteristic streams subject to LDR treatment 
standard requirements that will be decharacterized before injection), 
both on the day before and the day after successful implementation of 
pollution prevention. Results of this monitoring must be reported to 
the EPA Region or authorized State on a one-time basis. The Agency had 
solicited comment on whether more than one day is needed for 
monitoring. Several commenters were concerned that certain pollution 
prevention methods would take several weeks, not one day, to show 
results. It should be noted that the Agency did not intend for the 
pollution prevention method to show results in one day. Results should 
be achieved by the effective date of the rule for the facility to be in 
compliance, and the pollution prevention method should have been 
employed no earlier than 1990. The facility must also include a 
description of the pollution prevention method used (including any 
recycling alternative). In addition, the facility will monitor and keep 
on-site records of the results on a quarterly basis (this time period 
is selected to match the quarterly monitoring already required under 
SDWA regulations at 40 CFR 146.13 (b)). If the facility changes its 
means of complying with this alternative, it must renotify the EPA 
Region or authorized State, and again document the basis for its 
compliance by monitoring.

D. De Minimis Volume Exemption

    EPA is finalizing the de minimis exemption proposed. 60 FR at 
11714-11715. The terms of the exemption are that if decharacterized 
wastewaters comprise no more than 1% of the total injectate, if the 
total volume of the characteristic streams do not exceed 10,000 gallons 
per day, and if underlying hazardous constituents are

[[Page 15577]]
present in the characteristic wastes at concentrations less than 10 
times UTS at the point of generation, then the wastes are not 
prohibited from injection in a Class I non-hazardous deepwell (assuming 
the injectate is not hazardous at the point of injection). The Agency 
continues to believe that under these circumstances, the relatively 
small decharacterized hazardous waste streams would not appreciably 
alter the risks posed by the injection practice.
    Generally, the proposed approach was well received. Some commenters 
stated, however, that the de minimis volume exemption, as proposed, 
would allow excessively large volumes of routinely generated 
characteristic wastes to go untreated to disposal in deep wells, while 
others believe that the specific quantifying parameters are overly 
restrictive. The Agency analyzed potential risks associated with 
concentrations of 5 contaminants detected in Class I facility waste 
streams at 10, 20, and 50 times UTS. (This analysis was conducted in 
conjunction with revising the Regulatory Impact Analysis For 
Underground Injected Wastes for this rule. See 60 FR 11715.) In brief, 
risk estimates for 4 geologic settings and 2 well malfunction scenarios 
were found to be below levels of regulatory concern at 10 and 20 times 
UTS. However, at 50 times UTS, risk estimates for cancer and hazard 
index were above regulatory concern for a waste stream containing 
carbon tetrachloride, assuming an abandoned borehole failure within 500 
feet of the injection well. Taking into account the statutorily 
enumerated ``long-term uncertainties associated with land disposal'' 
(RCRA section 3004(d)(1)(A)), EPA believes the 10  x  UTS level to be 
well within the zone of reasonable values it could select as de 
minimis. The one percent volumetric requirement is consistent with 
other longstanding de minimis exemptions for wastewater management 
systems in the subtitle C rules (see Sec. 261.3(a)(2)(iv) (A) and (E)), 
and would normally cap the total volume of characteristic injectate at 
approximately 1100 gallons per day, given average Class I UIC non-
hazardous injection rates.
    At a rate of 1100 gallons per day, 10 x UTS for carbon 
tetrachloride would mean a mass loading of approximately 165 mg of the 
constituents being injected each day. Mass loadings for the other 
hazardous constituents would similarly be modest. EPA again believes 
that these small mass loadings would have de minimis effect on the risk 
potential posed by the injection practice and consequently should be 
exempted from the prohibition.

    EPA is promulgating the treatment standards that were proposed for 
wastes from the carbamate industry specified above.
    The preamble of the proposed rule described the basis for these 
treatment standards in greater detail (60 FR 11720). For background 
information on waste characterization data, data gathering efforts, and 
applicable technologies, see the Best Demonstrated Available Technology 
(BDAT) Background Document for Newly Listed or Identified Wastes from 
the Production of Carbamates.
    The concentration-based treatment standards being promulgated today 
for carbamate wastewaters and nonwastewaters are at UTS levels for 
certain constituents, and at newly-established levels for other 
constituents that are today being added to the UTS list. The UTS 
standards have already been promulgated for 21 of the constituents of 
concern (16 organic constituents and 5 metals). The Agency is 
promulgating new UTS for 42 constituents associated with carbamate 
wastes. Forty of these constituents are chemicals produced by the 
carbamate industry which may be grouped into the following categories: 
carbamates and carbamate intermediates, carbamoyl oximes, 
thiocarbamates, and dithiocarbamates. Please refer to the Background 
Document for definitions of these chemical groups and the 
categorization of these 40 chemicals. The other 2 constituents for 
which new UTS are being promulgated (triethylamine, and o-phenylene 
diamine) are not carbamate products, but are hazardous constituents 
present at levels of regulatory concern in carbamate wastes.
    One commenter requested clarification on the applicability of the 
carbamate treatment standards, stating that the summary section of the 
proposed treatment standards said that treatment standards were being 
proposed for certain hazardous wastes ``including those from the 
production of carbamate pesticides'', whereas the section of the rule 
that directly addressed carbamate wastes referred to carbamates without 
the pesticide limitation. EPA points out in response that the final 
listing rule which defined the new waste codes does not limit the 
definition to pesticides only. The treatment standards being 
promulgated apply to all wastes which fit the definitions of the waste 
codes established in the final listing rule.
    One commenter stated that EPA exceeded its authority under RCRA 
section 3004 and violated the Administrative Procedure Act by preparing 
the proposed treatment standards and sending this rule to OMB well 
before the final listing had been promulgated. EPA points out that the 
proposed treatment standards were actually published after publication 
of the final listing rule. The proposed treatment standards were 
modified to conform with the changes that appeared in the final 
listing; thus, treatment standards were only proposed for those 
carbamate wastes whose listing had been promulgated in final form. 
Proposed standards for wastes whose listings were not finalized were 
eliminated from the proposed treatment standards rule. Given the 
statutory requirement described above (i.e., the requirement to 
finalize LDR treatment standards six months after the listing is 
finalized), Congress must have envisioned that the two rulemaking 
activities would occur in close proximity.
    One commenter had several objections to the proposed standards for 
thiocarbamate wastes, stating that 1) nonwastewater standards should 
not have been based on detection limits compiled from sampling and 
analysis performed as part of the listing process

[[Page 15584]]
because the Agency made errors in the sampling and analysis; 2) that 
EPA has no data to support the assertion that the proposed UTS limits 
can be met by thermal destruction technologies and that the source of 
the detection limit used to develop the nonwastewater standard was not 
clearly identified; and, 3) that no document was found in the record to 
support the proposed wastewater limit of 0.003 mg/l for thiocarbamate 
constituents (A2213, Butylate, Cycloate, EPTC, Molinate, Pebulate, 
Prosulfocarb, Triallate, Vernolate), based on granular activated carbon 
absorption, giving the commenter no basis to evaluate the achievability 
of this treatment standard.
    To respond, the nonwastewater limit for thiocarbamate wastes was 
actually based on a detection limit of 0.5 mg/kg by GC/NPD, identified 
in a general characterization report addressing the newly regulated 
constituents, rather than on the limit of 0.125 mg/kg by SW-846 8270B, 
identified in the sampling and analysis reports. The commenter has not 
yet provided any data to indicate that the proposed treatment standards 
for nonwastewaters cannot be met.
    The Agency has decided to promulgate a treatment standard of 0.042 
mg/l in wastewaters for the thiocarbamate constituents identified 
above. This standard is based on an analytical detection limit of 0.015 
mg/l for Butylate, identified in an activated carbon isotherm test 
performed by the Office of Water to support development of effluent 
guideline limitations. The Agency had proposed a wastewater limit of 
0.003 mg/l, based on data taken from the PEST (Pesticide Treatability 
Database) database containing treatability data for pesticides, 
prepared and maintained by RREL (Risk Reduction Engineering Laboratory) 
in Cincinnati, Ohio. However, upon review of the available data, the 
Agency has decided that the Office of Water data is more accurately 
representative of available wastewater treatment than the pilot-scale 
data from the PEST database, and has decided to change the final 
treatment standard accordingly.
    EPA is today clarifying that the LDRs do not apply to waste streams 
which were specifically exempted from the definition of hazardous waste 
in the final listing rule for carbamates. These waste streams include 
sludges from the biological treatment of K156 and K157 and streams 
which satisfy the concentration-based exemption from the definition of 
K156 and K157 codified at Sec. 261.3(a)(2)(iv)(G).
    The promulgation of treatment standards for carbamate wastes has 
greatly expanded the number of constituents covered by the Universal 
Treatment Standards at Section 268.48. The Agency wishes to clarify 
that only a very limited number of generators or treaters, such as 
manufacturers or users of carbamate products, are expected to have 
these new constituents present in their wastes. Therefore, affected 
parties may rely on process knowledge to determine if it is necessary 
to analyze for these constituents.
    The commenter has not yet provided any data to indicate that the 
proposed treatment standards cannot be met. The commenter did indicate 
an intention to submit biological treatment data for thiocarbamate 
wastes. This commenter was instructed to submit this data quickly (by 
the end of August) to allow the Agency time to give consideration to 
this data prior to issuing the final rule.

B. Spent Aluminum Potliners (K088)

K088--Spent potliners from primary aluminum reduction.

    EPA proposed to establish treatment standards for K088 expressed as 
numerical concentration limits (see 60 FR 11722) for the following 
constituents: acenapthene, anthracene, benz(a)anthracene, 
benzo(a)pyrene, benzo(b)fluoranthene, benzo(k)fluoranthene, 
benzo(g,h,i)perylene, chrysene, dibenz(a,h)-anthracene, fluoranthene, 
indeno(1,2,3-cd)pyrene, phenanthrene, pyrene, antimony, arsenic, 
barium, beryllium, cadmium, chromium, lead, mercury, nickel, selenium, 
silver, cyanide and fluoride. Today, EPA is promulgating these 
treatment standards as proposed. The nonwastewater treatment standards 
for cyanide, and the organic constituents, are based on a total 
composition concentration analysis. The nonwastewater treatment 
standards for fluoride, and the metal constituents, are based on 
analysis using the TCLP. All wastewater treatment standards are based 
on total composition concentration analysis.
1. Comments Received on the ``Inherently Waste-Like'' Determination
    The majority of the comments received on the issue of declaring 
K088 ``inherently waste-like'' opposed such a determination. As 
discussed in the proposal, declaring K088 inherently waste-like would 
require that all K088 treaters/recyclers obtain a RCRA Part B permit 
regardless of whether the K088 is recycled, reused, used as a feedstock 
in a process, or conventionally treated. The commenters asserted that 
this designation would discourage recycling/reuse and development of 
innovative technologies, and would be overly burdensome for many of the 
small companies pursuing recycling technologies.
    The Agency was persuaded by commenters that a determination of 
``inherently waste-like'' is unnecessary at this time. Instead, any 
determination of whether a particular K088 processing technology is a 
type of excluded recycling activity would need to be made on a case-by-
case basis by EPA Regions or authorized states. EPA was persuaded by 
commenters that allowing individual flexibility in making such a 
determination is desirable here.
    Criteria that are typically relevant in making any such 
determinations are set out (among other places) at 50 FR at 638 (Jan. 
4, 1985); 53 FR at 522 (Jan. 8, 1988); and 56 FR at 7159 and 7185 (Feb. 
21, 1991). EPA also repeats the concerns voiced in the proposed rule 
that spent aluminum potliners contain high concentrations of cyanides 
and polyaromatic hydrocarbons which may be conventionally treated by 
thermal recovery processes, and that these and other hazardous 
constituents are present in the potliners in concentrations well 
exceeding those found in the raw materials or products for which the 
spent potliners would be substituting. 60 FR at 11723 n. 11. Other 
concerns are that the thermal recovery processes appear to pose the 
same potential risks of harmful air emissions as processing hazardous 
wastes in industrial furnaces, that the residues of recovery processes 
may not be adequately treated, and that storage of spent potliners can 
(and indeed has) posed significant risk. Id. at 11723-24. EPA also 
repeats that many of these units may already be subject to the rules 
for industrial furnaces burning hazardous wastes, since those rules 
apply to industrial furnaces that burn hazardous wastes for energy 
recovery, material recovery, or destruction. Id. at 11722 and n. 10; 56 
FR at 7142; 50 FR at 49171-49174 (Nov. 29, 1985); 40 CFR 266.100.
    A consequence of EPA's decision to allow for individualized 
determinations is that it is also unnecessary (and indeed, not 
factually justified) to make a general determination of ``substantial 
confusion'' pursuant to 270.10(e)(2) which could establish an 
opportunity for interim status eligibility. That finding would have 
been premised on the generic inherently wastelike determination (see 60 
FR at 11723), which the Agency is not making. EPA is also not pursuing 
in this proceeding the idea of toxic air emission standards under 
section 112(d)(1) of the Clean Air Act for these sources. These sources 
could be subject to these standards if they are major (or, in some 
cases, area)

[[Page 15585]]
sources under section 112, but that determination need not be part of 
the present rulemaking.
2. Comments Received on Regulated Constituents
    EPA requested comment on regulating the phthalates: bis (2-
ethylhexyl) phthalate, di-n-butyl phthalate and di-n-octyl phthalate. 
These constituents have seemingly been detected in the untreated 
potliner and the treated residue; however, EPA believes that their 
presence may simply be due to lab contamination. Commenters 
overwhelmingly requested that these phthalates not be regulated. The 
Agency agrees and is not including any phthalates in the list of 
regulated constituents for K088.
    A number of commenters requested that benzo(a)pyrene be used as a 
surrogate for analyzing organics. The commenters were concerned that 
analytical costs for other PAHs would be excessive. EPA is not 
convinced that analyzing benzo(a)pyrene would be sufficient for 
determining proper treatment of all organics. The concentration of one 
constituent does not always reflect the concentration of similar 
constituents in a waste. Surrogate analyses assume that all PAHs are 
present at similar concentrations which may or may not be true. Because 
of the variability of concentrations found in K088 wastes, 
benzo(a)pyrene may not be present while other PAHs may be present. 
Analyzing only for benzo(a)pyrene or any other potential surrogate does 
not ensure the treatment to UTS concentrations of other PAHs. In 
addition, the Agency believes that since all of the PAHs are analyzed 
by a single method the cost increase for additional PAHs should not be 
significant. Therefore, the Agency does not believe the organic 
constituents monitored in K088 wastes should be limited to a surrogate 
indicator. EPA is allowing, however, flexibility in the waste analysis 
plans developed by the companies with their permit writers to analyze 
only for those constituents expected to be present in the generated 
K088.
    The Agency proposed to regulate fluoride in K088. While fluoride is 
not a ``hazardous constituent'', i.e., listed in Appendix VIII of part 
261, it is present in very high concentrations in K088 and is capable 
of causing substantial harm in the form of groundwater degradation, 
adverse ecological effects and potential adverse human health effects. 
The Agency's view thus is that, unless fluoride in this waste is 
treated, the legal standard in section 3004(m) would not be satisfied. 
That is, treatment would not ``substantially diminish the toxicity of 
the waste * * * so that short-term and long-term threats to human 
health and the environment are minimized.'' RCRA section 3004(m)(1). In 
addition, as discussed in the proposed rule, EPA reads the language in 
section 3004 (d)(1), (e)(1), and (g)(5) to require that land disposal 
may still be prohibited after treatment of hazardous constituents if 
the waste might still pose substantial hazards due to presence of other 
constituents or properties. 56 FR at 41168 (August 19, 1991); NRDC v. 
EPA, 907 F. 2d 1146, 1171-72 (D.C. Cir. 1990) (dissenting opinion). 
These hazards could be posed due to lack of treatment of other 
constituents in the waste, in this case, fluoride.
    The Agency requested comment on whether fluoride should be added to 
Appendix VIII, as well. The overwhelming response of the commenters is 
that fluoride should not be added to Appendix VIII. The Agency agrees 
that fluoride does not pose the same risks in other wastes because it 
does not occur in such high concentrations. Furthermore, adding 
fluoride to Appendix VIII has associated potential analytical costs 
which would be unwarranted. Therefore, even though the Agency is 
regulating fluoride in K088, it is not adding it to Appendix VIII at 
this time.
3. Comments Received on Data
    Several comments were received regarding EPA's use of data on K088. 
One comment in particular suggested that EPA ignored relevant data 
gathered by the Aluminum Association. The Agency did not ignore these 
data. They were submitted after the proposal and are currently in the 
docket for this final rule. The Agency has reviewed these data and 
found that they do not support any changes to the proposed treatment 
standards that are being finalized in this rule. This issue is 
discussed in greater detail in the Response to Comments background 
document.
4. Comments Received on Technical Basis for BDAT
    There were a number of comments submitted on the technical basis 
for the numerical treatment standards. As described in the preamble to 
the proposed rule, most of the treatment standards are taken from the 
universal treatment standards (UTS) (59 FR 47988, September 19, 1994) 
which were developed for each constituent by evaluating all existing 
Agency data from various technologies. The exception to the UTS for 
K088 constituents is the fluoride treatment standard, which was taken 
from the Reynolds delisting petition. While K088 is a unique waste, 
available data indicate that these UTS levels can be routinely 
achieved.
    There seemed to be some confusion in that some commenters believed 
that EPA was proposing a required technology for the treatment of K088. 
This is not the case. The longstanding position of the Agency is when 
numerical treatment levels are established under the LDR program, any 
treatment technology (other than impermissible dilution) can be used to 
achieve those levels.
    Additional K088 comments along with EPA's responses are provided in 
the Response to Comments Background Document located in the docket for 
this rule.

VI. Improvements to the Existing Land Disposal Restrictions Program

A. Completion of Universal Treatment Standards

1. Addition of Constituents to Table 268.48
    As discussed in the section on carbamate wastes, EPA is today 
adding 42 new constituents to the table of universal treatment 
standards (Table 268.48), for which treatment standards are being 
promulgated today.
2. Wastewater Standard for 1,4-Dioxane
    EPA proposed on March 2, 1995 (60 FR 11702), to establish a 
wastewater treatment standard for 1,4-dioxane. 1,4-Dioxane was the only 
UTS constituent for which EPA had promulgated a nonwastewater treatment 
standard but not a wastewater standard. At that time, the Agency 
proposed a wastewater UTS for 1,4-dioxane of 0.22 mg/l. This proposed 
standard was based on the maximum daily limit for 1,4-dioxane that had 
been developed as part of the proposed effluent guidelines for the 
pharmaceutical industry (60 FR 21592, May 2, 1995). This standard was 
based on a transfer of distillation performance data from methanol to 
1,4-dioxane.
    Today, the Agency is promulgating a revised treatment standard for 
wastewater forms of 1,4-dioxane based on 5 data points. This data was 
submitted by one of the commenters and represents actual treatment of 
wastewaters containing 1,4-dioxane. The Agency prefers to use actual 
treatment data in lieu of a data transfer whenever possible. These data 
show that wastewaters containing between 2265-7365 mg/l of 1,4-dioxane 
can be treated by distillation to levels between 3-7 mg/l, representing 
a 99.9% removal rate for the dioxane. As a result of this data 
submittal, the Agency is today promulgating a UTS of 12.0 mg/l for 1,4-

[[Page 15586]]
dioxane wastewaters based on the performance of distillation. The 
standard was calculated following the standard methodology employed by 
EPA in developing all BDAT treatment standards.
    Comments received on the wastewater treatment standard for 1,4-
dioxane focused on three major points: (1) The unavailability, at the 
time of proposal, of data from the effluent guidelines proposed rule 
for the pharmaceutical industry, from which the proposed standard had 
been derived; (2) the inappropriateness of transferring distillation 
data from methanol to 1,4-dioxane (based on the effluent guidelines 
data); and (3) analytical difficulties inherent in analyzing for 1,4 
dioxane in wastewater.
    In the proposed rule, EPA referenced effluent guidelines data that 
would be made available to support the proposed wastewater treatment 
standard for 1,4-dioxane (60 FR 11727, footnote 13). Although the 
Agency believed that these data would be available for public 
inspection shortly after signature of the proposed rule, this was not 
the case. The data were available one day following the close of the 
comment period on the Phase III proposed rule. As a result, many 
comments were received that criticized the Agency for not providing 
appropriate pubic review of data that was used to develop a treatment 
standard.
    In light of the delayed release of the effluent guidelines data, 
the Agency decided to accept comments on these data and the proposed 
1,4-dioxane treatment standard for 30 additional days. In addition, the 
Agency provided notice of this extension to all commenters of the 
proposed rule. Several comments were received in response to this memo. 
Most of the commenters who had raised issue with the proposed standard 
commented on the EPA memo.
    In response to the second concern raised by commenters, the Agency 
has received actual wastewater treatment data on 1,4-dioxane and as 
such has developed a UTS based on that data. As stated earlier, the 
Agency prefers to use actual constituency data from available treatment 
technology in lieu of transferred data from other constituents whenever 
feasible.
    Finally, several commenters raised concerns regarding the 
analytical difficulties of reliably detecting and quantifying 1,4-
dioxane in wastewater. CMA, in particular, stated that any UTS under 20 
mg/l for 1,4-dioxane would be impractical. Other commenters noted 
extreme variability and difficulty in testing for the presence of 1,4-
dioxane in wastewaters. While the analytical results provided by one of 
the commenters did show some irregularities, a comprehensive analytical 
protocol was not provided by the any of the comments which would be 
needed to fully assess their concerns regarding 1,4-dioxane. As such, 
the Agency believes that there should be no difficulty in analyzing for 
1,4-dioxane in wastewater. Analysis can be accomplished by either 
direct injection into a GCFID (SW 846, Method 8015B) or a more 
sensitive analysis involving the injection of an azeotropic distillate 
preparation into a GCFID (SW-846, Method 5031).
3. Revision to the Acetonitrile Standard
    EPA proposed to raise the UTS for the nonwastewater form of 
acetonitrile from 1.8 mg/kg to 38 mg/kg. Commenters generally supported 
this revision for the reasons given in the proposed rule. Therefore the 
Agency is promulgating this revised treatment standard in this rule for 
the reasons stated at 60 FR 11729.
    Related to this, EPA also proposed revoking the special wastewater/
nonwastewater definition for acrylonitrile wastes (K011/13/14), 
recognizing that these nonwastewaters could consist of over 90% water, 
and that wastewater treatment is an appropriate means of treating these 
wastes. Commenters agreed with this, and the Agency is finalizing this 
today.

B. Aggressive Biological Treatment as BDAT for Petroleum Refinery 
Wastes

    EPA had solicited comment on whether to specify aggressive 
biological treatment (ABT) as the treatment standard for 
decharacterized petroleum refining wastewaters. The Agency is not 
establishing such a treatment standard in this final rule, but is 
instead promulgating a reduction in the frequency of monitoring 
required for those facilities using ABT to treat their wastes. The 
reasons for this are discussed below.
    This issue was raised by the American Petroleum Institute (API), 
which had submitted data to the Agency on ten of its facilities that 
used aggressive biological treatment. Along with the data, API 
requested that EPA specify aggressive biological treatment as the 
treatment standard for their wastes. Such a standard, which would 
operate in lieu of UTS, would, in API's view, provide adequate 
treatment and could reduce their monitoring burden. In a similar vein, 
CMA commented that EPA should specify an optional treatment method 
(biological treatment) as an alternative to meeting UTS for underlying 
hazardous constituents reasonably expected to be present in 
characteristic wastes.
    The Environmental Technology Council (ETC) opposed setting ABT as a 
new technology-specific treatment standard. They argued that biological 
treatment only partially destroys underlying hazardous constituents. 
They also felt that reducing the monitoring burden is inadequate 
justification for creating a new technology-specific standard.
    As discussed in the preamble to the proposed rule (60 FR at 11719), 
biotreatment systems vary in performance both in general and as to 
specific constituents; the Agency is therefore reluctant to designate 
ABT as BDAT based on data from only ten facilities. The main reason 
given by both API and CMA for having a treatment method as the 
treatment standard was the elimination of the compliance monitoring 
burden. Although we agree with ETC that reducing monitoring burden is 
not an adequate justification for creating a new technology-specific 
treatment standard, EPA is certainly willing to consider more efficient 
means of ensuring compliance with LDR requirements.
    Therefore, EPA is not designating ABT as BDAT, but is, however, 
requiring that decharacterized wastes affected by today's rule, which 
are managed in a wastewater treatment system involving ABT, must be 
monitored annually to ensure compliance with the treatment standards 
for underlying hazardous constituents. Other decharacterized wastes 
affected by today's rule must be monitored quarterly. EPA has been 
reviewing the paperwork burden posed by the LDR program; this was 
discussed in the supplemental notice to the LDR Phase IV proposed rule 
(61 FR 2338, January 25, 1996). As part of this paperwork burden 
reduction effort, the Agency is considering reducing the monitoring 
burden for all facilities complying with LDRs. The Agency considers 
reducing the monitoring burden for facilities treating wastewater with 
ABT to be a positive step towards this goal, and therefore believes it 
is justified. Reductions of this type for other types of treatment will 
be explored in future rulemakings.

C. Dilution Prohibition

    Under the existing LDR dilution prohibition (40 CFR 268.3), burning 
inorganic metal-bearing hazardous wastes can be a form of impermissible 
dilution. On May 27, 1994, the Assistant Administrator for the Office 
of Solid Waste and Emergency Response issued

[[Page 15587]]
a Statement of Policy which clarified this point (59 FR 27546-27547). 
Today the Agency is codifying and quantifying these principles.
    As discussed in the proposed rule, impermissible dilution may occur 
when wastes not amenable to treatment by a certain method (i.e., 
treated very ineffectively by that treatment method) are nevertheless 
`treated' by that method (55 FR 22666, June 1, 1990; 52 FR at 25778-
25779, July 8, 1987). Today's rule provides a general distinction 
between ``adequate treatment'' and potential violations of the dilution 
prohibition.
1. Inorganic Metal-Bearing Wastes
    The Agency has evaluated the hazardous wastes and has determined 
that 43 of the RCRA listed wastes (as set forth in 40 CFR part 261) 
typically appear to be inorganic hazardous wastes that do not contain 
organics, or contain only insignificant amounts of organics, and are 
not regulated for organics. BDAT for these inorganic, metal-bearing 
listed wastes is metal recovery or stabilization. Thus, impermissible 
dilution may result when these wastes are combusted. When an inorganic 
metal-bearing hazardous waste with insignificant concentrations of 
organics is placed in a combustion unit, legitimate treatment for 
purposes of LDR ordinarily is not occurring. No treatment of the 
inorganic component occurs during combustion, and therefore, metals are 
not destroyed, removed, or immobilized. Since there are no significant 
concentrations of organic compounds in inorganic metal-bearing 
hazardous wastes, it cannot be maintained that the waste is being 
properly or effectively treated via combustion (i.e., thermally treated 
or otherwise destroyed, removed, or immobilized). For this reason, 
combustion of inorganic wastes is not a ``metho[d] of treatment * * * 
which substantially diminish[es] the toxicity of the waste or 
substantially reduce[s] the likelihood of migration of hazardous 
constituents from the waste * * *'' (RCRA Sec. 3004(m)) and so is not a 
permissible method of treatment under that provision.
    In terms of the dilution prohibition, if combustion is allowed as a 
method to achieve a treatment standard for these wastes, metals in 
these wastes will be dispersed to the ambient air and will be diluted 
by being mixed in with combustion ash from other waste streams. 
Adequate treatment (stabilization or metal recovery to meet LDR 
treatment standards) has not been performed and dilution has occurred. 
It is also inappropriate to regard eventual stabilizing of such 
combustion ash as providing adequate treatment for purposes of the 
LDRs. Simply meeting the numerical BDAT standards for the ash fails to 
account for metals in the original waste stream that were emitted to 
the air and for reductions achieved by dilution with other materials in 
the ash. (In most cases, of course, the metal-bearing wastes will have 
been mixed with other wastes before combustion, which mixing itself 
could be viewed as impermissible dilution).
    These inorganic, metal-bearing hazardous wastes should be--and are 
usually--treated by metal recovery or stabilization technologies. These 
technologies remove hazardous constituents through recovery in 
products, or through immobilization, and are therefore permissible BDAT 
treatment methods.
    There are eight characteristic metal wastes; however, only wastes 
that exhibit the TC as measured by both the TCLP and the EP for D004-
D011 are presently prohibited (see 55 FR 22660-22662, June 1, 1990). 
EPA recently proposed prohibition and treatment standards for wastes 
identified as hazardous solely because they exhibit the TC (60 FR at 
43682, August, 22, 1995). Characteristic wastes, of course, cannot be 
generically characterized as easily as listed wastes because they can 
be generated from many different types of processes. For example, 
although some characteristic metal wastes do not contain organics or 
cyanide or contain only insignificant amounts, others may have organics 
or cyanide present which justify combustion, such as a used oil 
exhibiting the TC characteristic for a metal. Thus, it is difficult to 
say which D004-D011 wastes would be impermissibly diluted when 
combusted, beyond stating that as a general matter, impermissible 
dilution would occur if the D004-D011 waste does not have significant 
organic or cyanide content but is nevertheless combusted.
    An ``inorganic metal-bearing waste'' is one for which EPA has 
established treatment standards for metal hazardous constituents, and 
which does not otherwise contain significant organic or cyanide 
content. The table being promulgated in 40 CFR part 268, Appendix XI is 
the list of waste codes for which EPA regulates only metals that are 
affected by this rule.
2. Inorganic Metal-Bearing Wastes Not Prohibited Under the LDR Dilution 
Prohibition
    Combustion of the following inorganic metal-bearing wastes is not 
prohibited under the LDR dilution prohibition: (1) wastes that, at the 
point of generation, or after any bona fide treatment such as cyanide 
destruction prior to combustion, contain hazardous organic constituents 
or cyanide at levels exceeding the constituent-specific treatment 
standard for UTS; (2) organic, debris-like materials (e.g., wood, 
paper, plastic, or cloth) contaminated with an inorganic metal-bearing 
hazardous waste; (3) wastes that, at point of generation, have 
reasonable heating value such as greater than or equal to 5000 Btu/lb 
(see 48 FR 11157, March 16, 1983); (4) wastes co-generated with wastes 
that specify combustion as a required method of treatment; (5) wastes, 
including soil, subject to Federal and/or State requirements 
necessitating reduction of organics (including biological agents); and 
(6) wastes with greater than 1% Total Organic Carbon (TOC).
    Several commenters want EPA to add additional criteria. One 
commenter recommended adding a seventh criterion, i.e., combustion that 
results in a significant reduction in volume. Several commenters 
recommended adding a seventh criterion to allow combustion of lab 
packs. The Agency is not persuaded that a seventh criterion is 
necessary. It has determined that volume reduction is not a sufficient 
reason to allow the combustion of inorganic metal-bearing wastes 
because metals are neither destroyed nor immobilized, and it is 
possible that a significant amount of metal is being transferred to 
another media. As for lab packs, in the Phase II final rule (59 FR 
47982, September 19, 1994), the Agency specifically addressed lab pack 
issues when it revised 268 Appendix IV to specify those wastes that are 
prohibited from inclusion in lab packs destined for combustion. Today's 
dilution prohibition does not supersede the streamlined treatment 
standards promulgated in the Phase II final rule. Therefore, metal-
bearing inorganic wastes may be included in a lab pack unless it is 
prohibited under the list of wastes in 268 Appendix IV.
3. Cyanide-Bearing Wastes
    A commenter questioned why EPA allows the presence of cyanide to 
justify combustion when there are adequate alternative treatment 
methods for that waste constituent. This approach was adopted because 
cyanide is destroyed--i.e., effectively treated and not diluted--by 
combustion. Existing LDR rules, in many cases, identify combustion as 
an appropriate BDAT for destruction of cyanide-bearing wastes. See, 
e.g., treatment standards for F009, F010, and F011. The LDR Phase III 
proposal solicited comments on whether the

[[Page 15588]]
cyanide criterion should be dropped. Several commenters strongly 
supported the continued use of combustion as a treatment method for 
cyanide-bearing wastes, stating that combustion is the most efficient 
and effective method for treating cyanide wastes. One commenter, ETC, 
supported dropping the cyanide criterion because of the existence of 
alternative non-combustion technologies to treat inorganic cyanide-
bearing wastes without dispersing metals. The Agency disagrees; 
combustion, when properly conducted, can effectively destroy all the 
cyanide in a waste. In the Agency's view, this indicates that cyanide 
wastes which are treated by combustion are not being diluted 
impermissibly. This issue of whether metals are being dispersed would 
be addressed through substantive controls on the combustion unit.
4. Table of Inorganic Metal Bearing Wastes
    The table being promulgated in 40 CFR part 268, Appendix XI today 
indicates the list of waste codes for which EPA regulates only metals 
and/or cyanides that would be affected by this proposed rule. Except 
for P122, this list is identical to the list originally published in 
the aforementioned Policy Statement on this subject. The Agency is 
removing P122 (Zinc Phosphide greater than 10%) from the list of 
restricted inorganic metal-bearing wastes, because the Agency has 
previously promulgated a treatment standard of INCIN for the 
nonwastewater forms of this waste. See 40 CFR 268.40. The policy memo 
was in error on this point. EPA wishes to clarify that this dilution 
prohibition is limited to the 51 waste codes in this table. In 
addition, if an Appendix IX waste meets any of the six criteria 
discussed above, it would be permissible to combust the waste despite 
the fact that it is an Appendix IX waste.

D. Expansion of Treatment Options That Will Meet the LDR Treatment 
Standard ``CMBST''

    EPA is modifying the treatment standard expressed as INCIN, which 
specifies hazardous waste incineration, to CMBST, which allows 
combustion in incinerators, boilers and industrial furnaces. EPA also 
solicited comment on whether the Catalytic Extraction Process, for 
which Molten Metal Technology received a determination of equivalent 
treatment under Sec. 268.42(b), should also be allowed for all wastes 
which have a treatment standard of CMBST, and whether there are other 
technologies which are equivalent to CMBST. Commenters supported the 
inclusion of the Catalytic Extraction Process (CEP), and since the 
Agency has determined that (properly operated) it performs in a manner 
equivalent to other combustion technologies, is adding it to the CMBST 
standard. Molten Metal Technology commented that the CEP is not in fact 
a combustion technology, and the Agency has attempted to reflect this 
in the definition. One commenter, Exide Corporation, requested that 
their plasma arc process for the recovery of lead also be added to the 
definition of CMBST. The Exide plasma arc process is in fact an 
industrial furnace under Sec. 260.10, and is therefore already 
considered part of the definition of CMBST.
    EPA also notes that the new CMBST standard requires that wastes be 
thermally treated in units that either are subject to subtitle C 
standards, or, in cases where non-hazardous but prohibited wastes are 
being thermally treated, in accordance with applicable technical 
operating requirements. This situation could arise, for example, if a 
decharacterized waste were then being thermally treated. Such a waste 
need not be managed in a hazardous waste combustion unit. The 
regulatory language makes clear that non-hazardous waste combustion 
units can be utilized. In fact, the predecessor to the CMBST standard--
INCIN--allowed nonhazardous incinerators to be an eligible type of unit 
because the INCIN standard allowed burning in units subject to 
applicable emissions standards, which standards did not necessarily 
have to include subtitle C standards (59 FR 48002, Sept. 19, 1994, and 
60 FR 242, June 3, 1995). This language was omitted inadvertently from 
the CMBST standard, and is being restored in today's rule.

E. Clean Up of 40 CFR Part 268

    EPA is finalizing changes to the LDR program to achieve the goal of 
simplified regulations.
1. Section 268.8
    Because treatment standards for all scheduled wastes were 
promulgated in the Third Third rule in 1990, the Sec. 268.8 ``soft 
hammer'' requirements are no longer necessary. Therefore, Sec. 268.8 is 
removed from part 268.
2. Sections 268.10-268.12
    The purpose of Subpart B of 268 was to set out a schedule for 
hazardous wastes by the date when treatment standards were to be 
established. Deadlines in all three of these sections were met on time, 
and the wastes are subject to treatment standards. Therefore, these 
three sections are no longer necessary, and are removed.
3. Section 268.2(f)
    With the promulgation of UTS in the LDR Phase II final rule (59 FR 
47982, September 19, 1994), distinctions in the definitions of 
wastewaters are unnecessary. The Agency is therefore removing 
paragraphs (1)-(3) from Sec. 268.2(f).
4. Corrections to Proposed Rule Language
    A number of commenters pointed out properly that EPA had proposed 
an amendment to Sec. 268.9 of the rules which would have the effect of 
subjecting all listed wastes which also exhibit a characteristic of 
hazardous waste to evaluate whether the waste contains underlying 
hazardous constituents not covered by the treatment standard for the 
listed waste, and if so, to treat for them. See 60 FR at 11741. EPA 
agrees with the commenters that this provision is unnecessary and is 
not adopting it. (In fact, the Agency did not intend any far-reaching 
change in proposing the revised language.) The provision is unnecessary 
because EPA already evaluated which hazardous constituents are present 
in listed wastes at the time of developing the treatment standards (any 
of the Background Documents supporting the treatment standards 
indicates the sampling done, and that the sampling encompassed the 
whole range of hazardous constituents potentially present). There is no 
need to duplicate this effort. Consequently, the Agency is not amending 
Sec. 268.9(b).
    Other commenters pointed out that the proposed changes to the de 
minimis exemption in Sec. 268.1(e)(4)(i) (see 60 FR 11740) 
inadvertently omitted the language which states that de minimis losses 
are not prohibited. That language has been put back into the final rule 
language.

VII. Capacity Determinations

A. Introduction

    This section summarizes the results of the capacity analysis for 
the wastes covered by this rule. For background information on data 
sources, methodology, and a summary of each analysis, see the 
Background Document for Capacity Analysis for Land Disposal 
Restrictions, Phase III--Decharacterized Wastewaters, Carbamate Wastes, 
and Spent Potliners, found in the docket for today's rule. For EPA's 
responses to capacity-related comments, see the Response to Capacity-
Related Comments Received on the Phase III

[[Page 15589]]
Land Disposal Restrictions Rulemaking, also found in the docket for 
today's rule.
    In general, EPA's capacity analysis methodologies focus on the 
amount of waste to be restricted from land disposal that is currently 
managed in land-based units and that will require alternative treatment 
as a result of the LDRs. The quantity of wastes that are not managed in 
land-based units (e.g., wastewaters managed only in RCRA exempt tanks, 
with direct discharge to a POTW) is not included in the quantities 
requiring alternative treatment as a result of the LDRs. Also, wastes 
that do not require alternative treatment (e.g., those that are 
currently treated using an appropriate treatment technology) are not 
included in these quantity estimates.
    EPA's decisions on whether to grant a national capacity variance 
are based on the availability of alternative treatment or recovery 
technologies. Consequently, the methodology focuses on deriving 
estimates of the quantities of waste that will require either 
commercial treatment or the construction of new on-site treatment 
systems as a result of the LDRs--quantities of waste that will be 
treated adequately either on site in existing systems or off site by 
facilities owned by the same company as the generator (i.e., captive 
facilities) are omitted from the required capacity estimates.

B. Capacity Analysis Results Summary

    For the decharacterized ICR and TC wastes managed in CWA, CWA-
equivalent, and Class I injection well systems, EPA estimates that 
between 85 and 500 million tons per year (estimated at end-of-pipe) 
will be affected as a result of today's rule. EPA believes that many 
affected facilities need time to build treatment capacity for these 
wastes, as wastewater volumes generally make off-site treatment 
impractical. Thus, EPA has determined that sufficient alternative 
treatment capacity is not available, and today is granting a two-year 
national capacity variance for decharacterized wastewaters.
    Commenters to the rule generally supported EPA's decision to grant 
a national capacity variance for decharacterized wastes managed in CWA, 
CWA-equivalent, and Class I injection well systems. Numerous other 
comments were received on issues such as those associated with the 
definition of point of generation for ICR and TC wastewaters and the 
applicability of today's rule to wastewater management units other than 
surface impoundments, such as stormwater impoundments, sumps, sewers, 
and trenches. The Response to Capacity-Related Comments Received on the 
Phase III Land Disposal Restrictions Rulemaking background document 
provides a detailed discussion of the capacity-related comments on 
decharacterized wastewaters and EPA's response to them.
    To assess the quantity of D003 wastes that could be affected by the 
rule other than those wastes managed in CWA and CWA-equivalent systems, 
EPA extracted information from the 1993 Biennial Reporting System (BRS) 
on the generation and management of D003 wastes. According to the BRS, 
approximately 2.2 million tons of D003 wastewaters are currently 
deepwell injected, 650 tons of D003 nonwastewaters are managed through 
land application, and 17,600 tons of D003 nonwastewaters are managed in 
``other'' disposal units (not specified in the BRS). These wastes may 
require additional treatment in order to meet the LDRs. In addition, 
some D003 waste that may be affected by the rule may not be reported in 
the BRS, because these wastes may not be considered hazardous by the 
generator once they have been decharacterized. Although EPA believes 
that in general there is adequate treatment capacity for these wastes, 
such capacity may not be immediately available. Therefore, EPA is 
granting a 90-day capacity variance for D003 wastes that are impacted 
by the rule and are not managed in CWA and CWA-equivalent systems in 
order to allow facilities time to determine whether their wastes are 
affected by this rule, and identify and locate alternative treatment 
capacity if necessary.
    EPA estimates that approximately 105,000--130,000 tons of newly 
listed wastes included in today's rule will require alternative 
treatment. In particular, approximately 4,500 tons of carbamate wastes 
(K156-K161, P127, P128, P185, P188-P192, P194, P196-P199, P201-P205, 
U271, U277-U280, U364-U367, U372, U373, U375-U379, U381-U387, U389-
U396, U400-U404, U407, U409-U411) will require alternative treatment. 
In addition, 100,000--125,000 tons (not including contaminated media) 
of spent aluminum potliners (K088) will require alternative treatment 
capacity.
    EPA received a number of comments on its capacity analysis for K088 
wastes. Most commenters disagreed with EPA's proposal not to grant a 
capacity variance for K088 wastes. Specifically, these commenters 
believe that EPA overestimated the quantity of available capacity and 
underestimated the quantity of required capacity. In performing the 
capacity analysis for the final rule, EPA considered all of the issues 
raised by the commenters and reexamined its estimates of both available 
and required capacity. EPA found that adequate treatment capacity does 
exist for K088 wastes, although the amount of treatment capacity 
appears to be just adequate to accommodate demand. However, some of the 
facilities capable of treating these wastes may require pretreatment 
such as grinding or crushing prior to accepting the waste. In order to 
allow facilities generating K088 adequate time to work out logistics 
such as transportation, pretreatment capacity, and contracting for 
treatment capacity, EPA has decided to grant a nine-month national 
capacity variance for these wastes--the time at which EPA estimates 
existing treatment capacity will be available as a practical matter. A 
detailed discussion of the final capacity analysis is provided in the 
Background Document for Capacity Analysis for Land Disposal 
Restrictions, Phase III--Decharacterized Wastewaters, Carbamate Wastes, 
and Spent Potliners and EPA's responses to the individual comments on 
the K088 capacity analysis are provided in the Response to Capacity-
Related Comments Received on the Phase III Land Disposal Restrictions 
Rulemaking, both of which are in the docket for today's rule.
    EPA has determined that there is adequate alternative treatment 
capacity available for the 4,500 tons of carbamate wastes generated 
each year and is therefore not granting a national capacity variance 
for these wastes.
    The quantities of radioactive wastes mixed with wastes included in 
today's rule are generated primarily by the U.S. Department of Energy 
(DOE). EPA estimates that 820 tons of high-level waste and 360 tons of 
mixed low-level waste that may be affected by this proposal will be 
generated annually by DOE. In addition, there are currently 7,000 tons 
of high-level waste, 10 tons of mixed transuranic waste, and 2,700 tons 
of mixed low-level waste in storage that may be affected by this rule. 
DOE currently faces treatment capacity shortfalls for high-level wastes 
and mixed transuranic wastes. Although DOE does have some available 
treatment capacity for mixed low-level wastes, most of this capacity is 
limited to treatment of wastewaters with less than one percent total 
suspended solids and is not readily adaptable for other waste forms. 
DOE has indicated that it will generally give treatment priority to 
mixed wastes that are already restricted under previous LDR rules. 
Therefore, EPA is granting a two-year national capacity variance to 
radioactive wastes mixed with the hazardous wastes affected by today's 
rule. Commenters to the proposed rule supported EPA's

[[Page 15590]]
decision to grant a national capacity variance for these wastes.
    Table 1 lists each RCRA hazardous waste code for which EPA is today 
promulgating LDR standards. For each code, this table indicates whether 
EPA is granting a national capacity variance for land-disposed wastes. 
Also, EPA is granting a three-month national capacity variance for all 
wastes in this rule to handle logistical problems associated with 
complying with the new standards.

VIII. State Authority

A. Applicability of Rules in Authorized States

    Under section 3006 of RCRA, EPA may authorize qualified States to 
administer and enforce the RCRA program within the State. Following 
authorization, EPA retains enforcement authority under sections 3008, 
3013, and 7003 of RCRA, although authorized States have primary 
enforcement responsibility. The standards and requirements for 
authorization are found in 40 CFR Part 271.
    Prior to HSWA, a State with final authorization administered its 
hazardous waste program in lieu of EPA administering the Federal 
program in that State. The Federal requirements no longer applied in 
the authorized State, and EPA could not issue permits for any 
facilities that the State was authorized to permit. When new, more 
stringent Federal requirements were promulgated or enacted, the State 
was obliged to enact equivalent authority within specified time frames. 
New Federal requirements did not take effect in an authorized State 
until the State adopted the requirements as State law.
    In contrast, under RCRA section 3006(g) (42 U.S.C. 6926(g)), new 
requirements and prohibitions imposed by HSWA take effect in authorized 
States at the same time that they take effect in unauthorized States. 
EPA is directed to carry out these requirements and prohibitions in 
authorized States, including the issuance of permits, until the State 
is granted authorization to do so.
    Today's rule is being promulgated pursuant to sections 3004(d) 
through (k), and 3004(m), of RCRA (42 U.S.C. 6924(d) through (k), and 
6924(m)). Therefore, the Agency is adding today's rule to Table 1 in 40 
CFR 271.1(j), which identifies the Federal program requirements that 
are promulgated pursuant to HSWA. States may apply for final 
authorization for the HSWA provisions in Table 1, as discussed in the 
following section of this preamble. Table 2 in 40 CFR 271.1(j) is also 
modified to indicate that this rule is a self-implementing provision of 
HSWA.

B. Abbreviated Authorization Procedures for Specified Portions of 
Today's Rule

    On August 22, 1995, EPA proposed in the Phase IV LDR notice an 
abbreviated authorization procedure that would also be used for certain 
parts of the Phase III LDR rule that are minor in nature (EPA also 
proposed to use this procedure for the Universal Treatment Standards 
(UTS) in the Phase II rule). This procedure is designed to expedite the 
authorization process by reducing the scope of a State's submittal, for 
authorization to a State certification and copies of applicable 
regulations and statutes. EPA would then conduct a short review of the 
State's request, primarily consisting of a completeness check (see 60 
FR 43686 for a full description of the proposed procedures). The parts 
of the Phase III rule to which the streamlined authorization procedures 
would be applicable are: (1) treatment standards for newly listed 
wastes, (2) improvements to the existing land disposal restrictions 
program, and (3) revisions and corrections to the treatment standards 
in Secs. 268.40 and 268.48. (Further discussion of this issue also is 
found in the supplemental proposal to the LDR Phase IV rule (61 FR 
2358, 2365, January 25, 1996)).
    Although EPA is firmly committed to streamlining the RCRA State 
authorization procedures, the Agency has decided not to finalize the 
proposed Category 1 authorization procedures for parts of the Phase III 
rule today's notice. EPA believes that public comments from both the 
August 22 proposal and comments submitted for the recent HWIR-
contaminated media proposal should be considered before finalizing new 
procedures for authorization. This full consideration will enable EPA 
to make the best decision regarding how the authorization process 
should work. EPA intends to finalize both the Category 1 and Category 2 
procedures at the same time.

C. Effect on State Authorization

    Because today's Phase III LDR rule is being promulgated under HSWA 
authority, those sections of today's rule that expand the coverage of 
the LDR program (e.g., to newly identified wastes) would be implemented 
by EPA on the effective date of today's rule in authorized States until 
their programs are modified to adopt these rules and the modification 
is approved by EPA.
    However, some of today's regulatory amendments are neither more or 
less stringent than the existing Federal requirements. EPA clarified in 
a December 19, 1994, memorandum (which is in the docket for today's 
rule) that EPA would not implement the Universal Treatment Standards 
(promulgated under HSWA authority in the Phase II LDR rule) separately 
for those States for which the State has received LDR authorization. 
EPA views any changes from the existing limits to

[[Page 15591]]
be neither more or less stringent since the technology basis of the 
standards has not changed. Accordingly, EPA will not implement the 
amendments to the UTS in today's LDR Phase III rule for those states 
with LDR authorization.
    Because today's rule is promulgated pursuant to HSWA, a State 
submitting a program modification may apply to receive interim or final 
authorization under RCRA section 3006(g)(2) or 3006(b), respectively, 
on the basis of requirements that are substantially equivalent or 
equivalent to EPA's. The procedures and schedule for State program 
modifications for final authorization are described in 40 CFR 271.21. 
It should be noted that all HSWA interim authorizations will expire 
January 1, 2003. (See Sec. 271.24 and 57 FR 60132, December 18, 1992.)
    Section 271.21(e)(2) requires that States with final authorization 
must modify their programs to reflect Federal program changes and to 
subsequently submit the modification to EPA for approval. The deadline 
by which the State would have to modify its program to adopt these 
regulations is specified in Sec. 271.21(e). This deadline can be 
extended in certain cases (see Sec. 271.21(e)(3)). Once EPA approves 
the modification, the State requirements become Subtitle C RCRA 
requirements.
    States with authorized RCRA programs may already have requirements 
similar to those in today's rule. These State regulations have not been 
assessed against the Federal regulations being proposed today to 
determine whether they meet the tests for authorization. Thus, a State 
is not authorized to implement these requirements in lieu of EPA until 
the State program modifications are approved. Of course, states with 
existing standards could continue to administer and enforce their 
standards as a matter of State law. In implementing the Federal 
program, EPA will work with States under agreements to minimize 
duplication of efforts. In most cases, EPA expects that it will be able 
to defer to the States in their efforts to implement their programs 
rather than take separate actions under Federal authority.
    States that submit official applications for final authorization 
less than 12 months after the effective date of these regulations are 
not required to include standards equivalent to these regulations in 
their application. However, the State must modify its program by the 
deadline set forth in Sec. 271.21(e). States that submit official 
applications for final authorization 12 months after the effective date 
of these regulations must include standards equivalent to these 
regulations in their application. The requirements a State must meet 
when submitting its final authorization application are set forth in 40 
CFR 271.3.

IX. Regulatory Requirements

A. Regulatory Impact Analysis Pursuant to Executive Order 12866

    Executive Order No. 12866 requires agencies to determine whether a 
regulatory action is ``significant.'' The Order defines a 
``significant'' regulatory action as one that ``is likely to result in 
a rule that may: (1) have an annual effect on the economy of $100 
million or more or adversely affect, in a material way, the economy, a 
sector of the economy, productivity, competition, jobs, the 
environment, public health or safety, or State, local, or tribal 
governments or communities; (2) create serious inconsistency or 
otherwise interfere with an action taken or planned by another agency; 
(3) materially alter the budgetary impact of entitlements, grants, user 
fees, or loan programs or the rights and obligations of recipients; or 
(4) raise novel legal or policy issues arising out of legal mandates, 
the President's priorities, or the principles set forth in the 
Executive Order.''
    The Agency estimated the costs of today's rule to determine if it 
is a significant regulation as defined by the Executive Order. The 
analysis considers compliance cost and economic impacts for both 
characteristic wastes and newly listed wastes affected by this rule. 
For characteristic wastes, the potential cost impacts of this rule 
depend on whether facilities' current wastewater treatment systems will 
meet the UTS levels or if additional treatment will be required. If 
current treatments are adequate, facilities will only incur 
administrative costs to have their permits revised as well as on-going 
monitoring costs. In general, the Agency expects that facilities will 
seek permit modifications, treatability variances, or certification of 
adequate POTW treatment because these compliance options can be 
implemented at much lower cost than the option requiring treatment to 
UTS levels. EPA estimates the total annualized costs of the rule for 
these wastes would range from approximately $197,000 to $598,000, of 
which $154,000 to $425,000 would be incurred at the 28 to 73 
potentially affected facilities in the organic chemical industry, and 
approximately $43,000 to $173,000 would be incurred at the 8 to 30 
potentially affected facilities in the petroleum refining industry. 
However, at the high end, if current wastewater treatment systems need 
to be augmented with additional treatment steps, the incremental 
compliance costs for today's rule could be as high as $1 million per 
affected facility. The Agency does not have adequate data to estimate 
how many, if any, facilities may require modification to their 
treatment facilities. The Agency did conduct a sensitivity analysis, 
considering the costs of the rule under two scenarios: (1) Assuming 
that 80 percent of the facilities comply with the rule by obtaining 
permit modifications and 20 percent comply by treating their wastes, 
and, (2) assuming that 60 percent comply by obtaining permit 
modifications and 40 percent comply by treating their wastes. Based on 
the first scenario, the estimated annualized costs of the rule would 
range from $6.6 million to $18.2 million. Based on the second scenario, 
the estimated annualized costs would range from $12.9 million to $35.7 
million. For newly listed wastes, the costs are substantially higher 
and will be incurred each year. These costs range from approximately 
$11.9 million to $47.3 million and are attributable to thermal 
treatment of aluminum potliner wastes (K088). Therefore, today's rule 
may be considered an economically significant rule. Because today's 
rule is significant, the Agency analyzed the costs, economic impacts, 
and benefits.
    This section of the preamble for today's rule provides a discussion 
of the methodology used for estimating the costs, economic impacts and 
the benefits attributable to today's rule, followed by a presentation 
of the cost, economic impact and benefit results. More detailed 
discussions of the methodology and results may be found in the 
background document, ``Regulatory Impact Analysis of the Land Disposal 
Restrictions Final Rule for the LDR Phase III Newly Listed and 
Identified Wastes,'' which has been placed in the docket for today's 
rule.
1. Methodology Section
    In today's rule, the Agency is establishing treatment standards for 
the following wastes: end-of-pipe standards for ignitable, corrosive, 
and reactive (ICR) wastewaters managed in CWA, CWA-equivalent systems, 
and UIC wells; Toxicity Characteristic pesticide (D012-17) and organic 
(D018-43) wastewaters managed in CWA, CWA-equivalent systems, and UIC 
wells; and newly listed wastes from two industries--spent aluminum 
potliners and carbamates.
    a. Methodology for Estimating the Affected Universe. In determining 
the costs, economic impacts, and benefits associated with today's rule, 
the Agency

[[Page 15592]]
estimated the volumes of waste affected by today's rule. The procedure 
for estimating the volumes of ICR waste and TC organic and pesticide 
waste, and newly listed wastes affected by today's rule is summarized 
below.
    First, the Agency examined all industries which might be likely to 
produce wastes covered under today's standards. Through reviewing 
comments to the Supplemental Notice of Data Availability published by 
the Agency in 1993, reviewing runs from the Biennial Reporting System 
(BRS) of volumes generated from particular industry sectors, as well as 
discussions with industry, and discussions with the Office of Water at 
EPA HQ, the Agency narrowed it down to 16 industries which would 
potentially have significant volumes of wastewater affected by today's 
rule.
    Using a host of databases and/or sources, the Agency collected data 
on the quantities, constituents, and concentrations of the volumes 
affected from each of the 16 industries. In addition, the Agency 
gathered any data on current management practices, plant design, etc. 
The following sources were used: Toxic Release Inventory (TRI), Section 
308 data from the Office of Water, Industrial Studies Database (ISDB), 
1991 Biennial Reporting System (BRS), primary summary and development 
documents data from effluent guidelines, TCRIA documents, data gathered 
in the capacity analysis performed for today's rule, as well as 
comments from potentially affected industries.
    The Agency obtained volume information for the newly listed 
wastes--spent aluminum potliners (K088) and carbamate wastes (K156-
161)--from the listing documents prepared for these wastes during the 
listing procedure.
    b. Cost Methodology. The cost analysis estimates the national level 
incremental costs which will be incurred as a result of today's rule. 
The cost estimates for both the baseline and post-regulatory scenarios 
are calculated employing: (i) the facility wastestream volume, (ii) the 
management practice (baseline or post-regulatory) assigned to that 
wastestream, and (iii) the unit cost associated with that practice. 
Summing the costs for all facilities produces the total costs for the 
given waste and scenario. Subtracting the baseline cost from the post-
regulatory cost produces the national incremental cost associated with 
today's rule for the given waste.
    The cost methodology section includes three sub-sections: (i) ICR 
and TC Pesticide and Organic Wastes Managed in CWA and CWA-Equivalent 
Systems, (ii) Newly Listed Wastes, (iii) Testing and Recordkeeping 
Costs.
    i. ICR and TC Pesticide and Organic Wastes Managed in CWA and CWA-
Equivalent Systems. The Agency employed the following approach to 
estimate the incremental costs for the ICR and TC wastes. First, using 
information available on the affected industries, the Agency created 
average-sized model facilities for each industry. Second, for a given 
model facility in an affected industry, the Agency used available unit 
cost data to develop costs for the baseline management practices 
(usually treatment in surface impoundments followed by discharge into 
receiving waters through a NPDES permit). Third, the Agency used data 
on the constituents and waste quantities for each industry, where 
applicable, to determine the necessary treatment required to reduce to 
UTS levels the constituents present. Fourth, the Agency used unit costs 
to develop costs for the post-regulatory management practices for the 
treatment requirements determined in the third step. Fifth, subtracting 
the baseline from the post-regulatory costs for an average facility in 
an industry sector and using the data available on the number of 
facilities affected within each industry, the Agency was able calculate 
the incremental cost for a given industry. Sixth, summing costs across 
affected industries, the Agency determined the incremental cost for the 
rule for the end-of-pipe treatment standards.
    ii. Newly Listed Wastes. The costs for treatment of spent aluminum 
potliners (K088) and carbamate wastes (K156-161) will be determined 
using data from the listings on baseline management practices, judgment 
on the technology(s) required to meet the UTS standards for these 
wastes, and available unit cost data.
    iii. Testing and Recordkeeping Costs. Testing and recordkeeping 
costs, including costs that facilities will incur for ensuring that 
hazardous constituents in characteristic waste are meeting new 
treatment standards and costs associated with permit modifications will 
be based upon an average, one-time testing cost, on-going monitoring 
costs, and an Information Collection Request, respectively.
    c. Economic Impact Methodology. The economic effects of today's 
rule are defined as the difference between the industrial activity 
under post-regulatory conditions and the industrial activity in the 
absence of regulation (i.e., baseline conditions).
    The Agency used (1) historic average capital expenditures for each 
industry, (2) historic average operating expenditures for each 
industry, (3) historic revenues, and (4) historic average pollution 
abatement and control expenditures (PACE) to determine the economic 
impacts. However, the Agency was unable to examine the impacts on a 
facility-specific basis due to lack of data. Therefore, the impacts are 
assessed on an industry-specific basis.
    d. Benefits Methodology. The approach for estimating benefits 
associated with today's rule involves three components: (i) estimation 
of pollutant loadings reductions, (ii) estimation of reductions in 
exceedances of health-based levels, and, (iii) qualitative description 
of the potential benefits. The benefits assessment is based upon the 
waste quantity and concentration data collected for the cost analysis. 
This incremental assessment focuses upon reductions in toxic 
concentrations at the point of discharge and does not consider any 
potential benefits resulting from reductions in air emissions or 
impacts on impoundment leaks and sludges which may occur as part of 
treating wastes to comply with the LDRs. It is expected that additional 
treatment to comply with the LDRs may result in risk reductions from 
air emissions, leaks, and sludges.
    EPA has conducted an assessment of the benefits related to the 
effects of the rule on newly listed spent aluminum potliners. These 
benefits depend on the incremental risk reductions that may result from 
treatment of the wastes. In conducting the risk assessment for spent 
aluminum potliners, EPA improved upon the fate and transport modeling 
approach used in the RIA. Specifically, in the RIA, EPA applied generic 
dilution/attenuation factors (DAFs) (which did not reflect constituent-
specific fate and transport processes, site-specific hydrogeological 
conditions, or waste characterization data) to relate the concentration 
of contaminants in the leachate to their concentration in a down-
gradient well. Instead, EPA used its Composite Model for Leachate 
Migration and Transformation Products (EPACMTP) to perform constituent-
specific fate and transport modeling. A summary of the analysis can be 
found in the Addendum to the RIA placed in the docket for this rule. 
EPA data indicate that approximately 120,000 metric tons of spent 
aluminum potliners are generated annually. EPA has not conducted an 
assessment of the benefits related to the effects of the rule on newly 
listed carbamate wastes. Because the Agency expects facilities to 
comply with LDRs through permit modifications, and because the quantity 
of waste is very small, benefits for

[[Page 15593]]
newly listed carbamate wastes are expected to be minimal.
    i. Estimation of Pollutant Loadings Reductions. An incremental 
approach was used to estimate reductions in pollutant loadings. For the 
baseline scenario, contaminant concentrations were based upon data or 
estimates of current effluent discharge concentration levels. For the 
post-regulatory scenario, concentration levels were assumed to equal 
UTS levels.
    ii. Estimation of Reductions in Exceedances of Health-Based Levels. 
The methods used for evaluating the benefits associated with cancer and 
noncancer risk reductions resulting from the rule entail comparing 
constituent concentration levels to health-based standards to evaluate 
whether implementation of the rule reduces concentration levels below 
levels that pose risk to human health.
    To estimate benefits from cancer risk reductions resulting from the 
rule, a simple screening analysis was performed. This analysis compared 
contaminant concentrations for the baseline and post-regulatory 
scenario to health-based levels for carcinogens. Further analysis may 
be undertaken to quantify benefits associated with facility/ 
wastestream combinations identified in the contaminant concentration 
comparisons.
    Benefits associated with reductions in non-cancer exceedances are 
estimated based upon comparisons of contaminant concentration levels in 
effluent discharges of the affected wastestreams to the reference 
health levels. These benefits are expressed in terms of the number of 
exceedances of health-based levels under the baseline scenario compared 
to the number of exceedances under the rule.
    iii. Qualitative Description of the Potential Benefits. A 
qualitative assessment of potential benefits likely to result from the 
rule is used where data are limited. The Agency acknowledges limited 
data availability in developing waste volumes affected, constituents, 
concentrations, cost estimates, economic impacts, and benefits 
estimates for the LDR Phase III rulemaking. The Agency continues to 
request comment from industry regarding constituents, concentrations, 
waste volumes, and current management practices.
2. Results
    a. Volume Results. The Agency has estimated the volumes of formerly 
characteristic wastes potentially affected by today's rule to total in 
the range of 33.5 to 500 million metric tons. The Agency requests 
comment on waste volumes affected by the LDR Phase III rule. For newly 
listed wastes, the analyses supporting the listing determination showed 
about 4,500 metric tons of carbamate wastes and 118,000 metric tons of 
spent aluminum potliners are potentially affected by this rule.
    b. Cost Results. For characteristic wastes, the potential cost 
impacts of this rule depend on whether facilities' current wastewater 
treatment systems will meet the UTS levels or if additional treatment 
will be required. If current treatments are adequate, facilities will 
only incur administrative costs to have their permits revised. EPA 
estimates the total annualized costs of the rule for these wastes would 
range from approximately $197,000 to $598,000, of which $154,000 to 
$425,000 would be incurred at the 28 to 73 potentially affected 
facilities in the organic chemical industry, and approximately $43,000 
to $173,000 would be incurred at the 8 to 30 potentially affected 
facilities in the petroleum refining industry. However, at the high 
end, if current wastewater treatment systems need to be augmented with 
additional treatment steps, the incremental compliance costs could be 
as high as $1 million per affected facility. The Agency does not have 
adequate data to estimate how many, if any, facilities may require 
modification to their treatment facilities. The Agency continues to 
request comment and data on how often additional treatment may be 
required.
    For newly listed wastes, the costs are substantially higher and 
will be incurred each year. These costs range from approximately $11.9 
million to $47.3 million and are attributable to thermal treatment of 
aluminum potliner wastes (K088). The Agency requests comment on where 
industry falls within this range.
    c. Economic Impact Results. The Agency has estimated the economic 
impacts of today's rule to represent less than one percent of historic 
pollution control and operating costs for the organic chemical and 
petroleum refining industries. However, for those facilities that may 
need to treat to UTS to comply with today's rule, costs could be more 
significant. The estimated compliance costs for treating newly listed 
spent aluminum potliners represents 40 percent of pollution control 
operating costs for aluminum reducers; however, treatment costs 
represent only one percent of total historic operating costs.
    d. Benefit Estimate Results. The Agency expects facilities to 
comply with the LDRs through permit modifications. As a result, the 
Agency has estimated the benefits associated with today's rule to be 
small. Assuming facilities comply with the rule by treating their 
affected wastestreams, loadings reductions estimates range between 
1,527 to 21,322 metric tons per year at 129 to 291 facilities (direct 
and indirect dischargers) involving 175 to 647 constituent/wastestream 
combinations. Ninety-eight percent of the reductions occur at organic 
chemicals facilities, with the remainder occurring at petroleum 
refiners. Estimated loadings reductions for direct dischargers range 
between 36 and 267 tons per year, representing between 0.03 and 0.2 
percent of total Toxic Release Inventory (TRI) chemical loadings to 
surface waters. For indirect dischargers, estimated loadings reductions 
range between 1,491 and 21,055 metric tons per year, representing 
between 0.8 and 11.0 percent of total TRI chemical loadings transferred 
to POTWs. Based upon the results of the screening and more detailed 
risk assessments, the estimated baseline risks associated with nine to 
twenty wastestreams (out of the 155 to 404 constituent/wastestream 
combinations potentially affected by the rule) exceed 10-6 under 
baseline conditions and three to six wastestreams with noncancer risk 
levels exceeding reference doses. These 12 to 26 wastestreams contain 
one of five constituents: aniline (9 to 19 wastestreams), acrylamide (0 
to 1 wastestream), pyridine (2 waststreams), barium compounds (1 
wastestream), and acetonitrile (0 to 2 wastestreams). For these 12 to 
26 wastestreams, EPA conducted a more detailed risk assessment, using 
site-specific data. Results of the more detailed risk assessment 
indicate that the benefits from the rule are small. EPA identified four 
wastestreams potentially posing cancer risk exceeding the threshold 
risk levels. Three wastestreams pose baseline cancer risk ranging from 
1  x  10-5 to 1  x  10-4 (due to exposure to aniline) which 
potentially would be reduced to between 8  x  10-8 and 3  x  
10-6 under the LDR Phase III rule. A fourth wastestream containing 
acrylamide poses baseline cancer risk at a level of 2  x  10-3. 
The rule is estimated to reduce this risk to between 2  x  10-4 
and 4  x  10-36. All four of these wastestreams are discharged to 
POTWs; if POTW treatment removes these constituents from the wastewater 
prior to discharge to surface water and/or if no drinking water intake 
is located downstream from the POTW's outfall, baseline risks will be 
lower. The Agency expects facilities to comply with the LDRs through 
permit modifications;

[[Page 15594]]
however, additional treatment may result in potentially significant 
risk reduction.
    EPA performed constituent-specific fate and transport modeling 
using its EPACMTP to further assess cancer and noncancer risks of spent 
aluminum potliners. Using these additional data, EPA assessment of 
baseline risks indicates that individual lifetime cancer risks increase 
to about 10-6 under central tendency assumptions and 10-3 
under high-end assumptions. In addition, the new estimates suggest that 
under high-end assumptions, baseline concentrations in drinking water 
may be high enough to present noncancer risks; previously, noncancer 
risks were estimated to be negligible. Consequently, the benefits of 
regulating spent aluminum potliners are higher than previously 
estimated. Under central tendency assumptions, individual lifetime 
cancer risks resulting from current waste management practices are 
slightly higher than post-regulatory risks (10-6 versus less than 
10-6); some incremental benefits may therefore be realized as a 
result of the LDRs. Under high-end assumptions, however, the regulation 
could reduce cancer risks by one or two order of magnitude, while 
noncancer risks could be eliminated. Although population risks would 
also be reduced correspondingly, EPA is unable to specify the magnitude 
of the exposed population.

B. Regulatory Impact Analysis for Underground Injected Wastes

    The Agency has completed a separate regulatory impact analysis for 
underground injected wastes affected by the LDR Phase III final rule. 
This analysis describes the regulatory impacts only to the Class I 
injection well universe. The new Phase III LDRs cover decharacterized 
ICR and TC organic wastes, and other newly-identified hazardous wastes 
that are distinctly industrial wastes injected by owners and operators 
of only Class I hazardous and non-hazardous injection wells.
    According to the available data outlined in the RIA, our best 
estimate indicates that of the 223 Class I injection facilities in the 
nation, up to 154 facilities will be affected by the new Phase III 
LDRs. Of these facilities, 100 inject nonhazardous waste and 54 inject 
hazardous waste. Combined, these facilities inject approximately 18 
billion gallons of waste annually into Class I wells. These Class I 
injection wells will now be required to either treat wastes onsite, 
segregate and ship affected wastes offsite for treatment and disposal, 
or file no migration petitions as outlined in the UIC regulations in 40 
CFR Part 148 (See 53 FR 28118, July 26, 1988, preamble for a mote 
thorough discussion of the no migration petition review process). 
Additional options for compliance with the final Phase III LDRs, 
including a de minimis exemption and a pollution prevention option 
discussed in detail elsewhere in this rule and in the final UIC RIA.
    Of the newly affected Class I facilities, 38 already have no 
migration exemptions approved by EPA, but they may be required to 
submit a petition modification to EPA due to the Phase III rule unless 
their original petition already addressed affected Phase III wastes, 
including underlying hazardous constituents in decharacterized wastes. 
In the cases where the petition already covers all hazardous wastes and 
underlying hazardous constituents in the injected waste stream (i.e., 
the injectate that was evaluated during the no migration petition 
process has not changed), no further Agency review of these petitions 
is necessary. For the facilities which do not have approved no 
migration exemptions, the rule will add compliance costs to those 
incurred as a result of previous rulemakings. The Agency analyzed costs 
and benefits for the final Phase III rule using the same approach and 
methodology developed in the Regulatory Impact Analysis of the 
Underground Injection Control Program: Proposed Hazardous Waste 
Disposal Injection Restriction (53 FR 28118) and subsequent LDR 
rulemaking. An analysis was performed to assess the economic effect of 
associated compliance costs for the additional volumes of injected 
wastes attributable to this rule.
    In general, Class I injection facilities affected by the LDR Phase 
III rule have several options. As previously outlined, some facilities 
will modify existing no migration petitions already approved by the 
Agency, others may submit entirely new petitions, and still others may 
accept the prohibitions and either continue to inject treated wastes or 
cease injection operations altogether. And some facilities with 
approved petitions already addressing Phase III wastes will have no or 
little additional compliance costs. EPA assessed compliance costs for 
Class I facilities submitting no migration petitions, employing 
alternative treatment, and/or implementing pollution prevention 
measures. Although facilities using pollution prevention/waste 
minimization to comply with the Phase III LDRs will likely lower 
overall regulatory compliance costs, these situations are site-specific 
and, therefore, EPA cannot estimate these costs savings at this time.
    For Class I facilities opting to use alternative treatment, the 
Agency derived costs for both treating wastes on-site, and/or shipping 
wastes and treating them off-site at a commercial facility. However, 
EPA believes that the segregation and transportation of large volumes 
of liquid wastes off-site is not very practical or cost-effective. This 
makes the off-site treatment scenario, at best, a highly conservative 
analysis and in actuality, a least likely and therefore discountable 
scenario. EPA expects that all injection facilities will opt for the 
most cost-effective approach in complying with the Phase III final rule 
and they will either submit a no migration petition or treat their 
wastes on-site. EPA also assumes that non-commercial facilities will 
segregate wastes for treatment on-site, whereas commercial facilities 
will find it more cost effective to not segregate LDR Phase III wastes. 
For the final rule, EPA estimates that the total annual compliance cost 
for petitions and alternative on-site treatment to industry affected by 
the new LDR Phase III prohibitions will range between $32.91 million to 
$34.08 million per year. The average annual compliance costs per 
affected facility employing on-site alternative treatment were 
$217,500. The range of costs for alternative treatment is the result of 
applying a sensitivity analysis. Only the incremental treatment costs 
for the new waste listings are calculated in this RIA. All of these 
costs will be incurred by Class I injection well owners and operators. 
The average annual compliance costs per affected facility employing on-
site alternative treatment were $217,500. The total annual compliance 
costs for the 154 potentially affected facilities would therefore be 
$33.4 million. These figures were derived by applying the probability 
of certain outcomes occurring, via the decision tree methodology 
described in the RIA, to the costs associated with those outcomes for 
each affected facility.
    Additionally, as part of the RIA analysis, the costs associated 
with three differing scenarios also were derived. These scenarios are 
represented by (1) a minimum case, where all facilities incur only 
petition costs, (2) a mid-line case, where all facilities incur 
treatment costs (commercial facilities treat on-site with no waste 
segregation while non-commercial facilities chose the least cost 
treatment option), and a maximum case, where all facilities incur both 
petition and treatment costs. Costs associated with these scenarios 
range

[[Page 15595]]
from $3.67 million per year for all facilities incurring only petition 
costs to $132.62 million per year for all facilities incurring both 
petition and treatment costs. Based on past EPA experience, there is 
little probability that all facilities will arrive at each of these 
possible outcomes. However, this indicated range provides an extreme 
lower and upper bound estimate for national compliance costs purposes.
    The benefits to human health and the environment in the RIA are 
generally defined as reduced human health risk resulting from fewer 
instances of ground water contamination. In general, potential health 
risks from Class I injection wells are extremely low.
    EPA conducted a quantitative assessment of the potential human 
health risks associated with two well malfunction scenarios. EPA 
developed a methodology described in the RIA to measure health risks of 
five Phase III contaminants: benzene, carbon tetrachloride, chloroform, 
phenol, and toluene. The results of these analyses show that most of 
the cancer risks calculated are below the 1  x  10-4 to 1  x  
10-6 risk range generally used by EPA to regulate exposure to 
carcinogens. Virtually all of the non-cancer risks are below a hazard 
index (HI) of 1, which represents a ratio used to compare the relative 
health risks posed by contaminants. Therefore, these cancer and non-
cancer risks calculated are below any levels of regulatory concern. 
Only two cancer risk estimates in the high end scenarios, those 
calculated for benzene and carbon tetrachloride, slightly exceeded the 
risk range to regulate exposure to carcinogens. Only one hazard index 
calculated for carbon tetrachloride exceeded EPA's level of concern of 
a ratio greater than 1. However, these results were derived from a 
scenario where an abandoned borehole (i.e. the ``failure pathway'') was 
in very close proximity to the injection well, substantial pumping of a 
drinking water well was occurring, and the local geology was typical of 
the highly transmissive East Gulf Coast Region. The assumptions used in 
deriving these results were based on conservative, upper-bound 
estimates, therefore the cancer and non-cancer risks represent worst-
case estimates. Considering the limitations imposed by the failure 
scenarios, and the documented low probability of Class I failures, the 
overall risks from failure of Class I injection wells would be below 
regulatory concern.
    There also is a potential qualitative benefit to the no-migration 
process for Class I nonhazardous wells. It is possible that the process 
would uncover certain wells that cannot satisfy the no-migration 
standard and indeed may not be suitable for Class I injection in any 
case. This proved to be true for Class I hazardous wells. However, 
notwithstanding this potential benefit, as noted in the early part of 
this preamble, the Agency does not regard this regulatory effort as 
deserving of the priority afforded it, due to the litigation-driven 
schedule and the D.C. Circuit's mandate, and would not be undertaking 
the effort at this time were it not for that mandate and schedule.
    The economic analysis of LDR Phase III compliance costs suggests 
that publicly traded companies probably will not be significantly 
affected. The limited data available for privately-held companies 
suggests, however, that they may face significant costs due to the 
proportionally larger expenses they may face due to the LDR Phase III 
rule.

C. Regulatory Flexibility Analysis

    Pursuant to the Regulatory Flexibility Act of 1980, 5 U.S.C. 601 et 
seq., when an agency publishes a notice of rulemaking, for a rule that 
will have a significant effect on a substantial number of small 
entities, the agency must prepare and make available for public comment 
a regulatory flexibility analysis that considers the effect of the rule 
on small entities (i.e.: small businesses, small organizations, and 
small governmental jurisdictions). Under the Agency's Revised 
Guidelines for Implementing The Regulatory Flexibility Act, dated May 
4, 1992, the Agency committed to considering regulatory alternatives in 
rulemakings when there were any economic impacts estimated on any small 
entities. (See RCRA sections 3004 (d), (e), and (g)(5), which apply 
uniformly to all hazardous wastes.) Previous guidance required 
regulatory alternatives to be examined only when significant economic 
effects were estimated on a substantial number of small entities.
    In assessing the regulatory approach for dealing with small 
entities in today's rule, for both surface disposal of wastes, the 
Agency considered two factors. First, data on potentially affected 
small entities are unavailable. Second, due to the statutory 
requirements of the RCRA LDR program, no legal avenues exist for the 
Agency to provide relief from the LDR's for small entities. The only 
relief available for small entities is the existing small quantity 
generator provisions and conditionally exempt small quantity generator 
exemptions found in 40 CFR 262.11-12, and 261.5, respectively. These 
exemptions basically prescribe 100 kilograms (kg) per calendar month 
generation of hazardous waste as the limit below which one is exempted 
from complying with the RCRA standards.
    Given these two factors, the Agency was unable to frame a series of 
small entity options from which to select the lowest cost approach; 
rather, the Agency was legally bound to regulate the land disposal of 
the hazardous wastes covered in today's rule without regard to the size 
of the entity being regulated.
    The Agency has, however, included an exemption covering injection 
facilities where the decharacterized portion of the injectate is 
minimal in absolute terms, as a percentage of the total injectate, and 
in hazardous constituent mass loadings. This de minimis exemption 
provides a measure of relief to both small and larger entities 
satisfying its terms.

D. Paperwork Reduction Act

    The information collection requirements in this rule have been 
submitted for approval to the Office of Management and Budget (OMB) 
under the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. Four 
Information Collection Request (ICR) documents have been prepared by 
EPA, as follows. OSWER ICR No. 1442.12 would amend the existing ICR 
approved under OMB Control No. 2050-0085. The additional information 
requirements for the Underground Injection Control (UIC) Program were 
submitted to OMB under ICR No. 0370.14; this will amend the existing 
UIC approval under OMB Control No. 2040-0042. OSWER ICR No. 1442.12 and 
UIC ICR No. 0370.14 have not been approved by OMB and the information 
collection requirements in those ICRs are not enforceable until OMB 
approves them. EPA will publish a document in the Federal Register when 
OMB approves the information collection requirements. Until EPA 
publishes a document displaying the valid OMB control number, persons 
are not required to respond to collections of information in these two 
ICRs. Two amendments to National Pollutant Discharge Elimination System 
(NPDES) ICRs were approved at proposal. These are ICR 0229.10 for the 
Discharge Monitoring Report, approved under OMB Control No. 2040-0004, 
and ICR 0226.11 for NPDES Applications, approved under OMB Control No. 
2040-0086.
    Copies of these ICRs may be obtained from Sandy Farmer, OPPE 
Regulatory Information Division; U.S. Environmental Protection Agency 
(2136); 401 M St., S.W.; Washington, D.C. 20460 or by calling (202) 
260-2740. Include the ICR numbers in any request. The information 
requirements for the

[[Page 15596]]
OSWER ICR and the UIC ICR are not effective until OMB approves them.
    The additional burden associated with the OSWER ICR 1442.12 is as 
follows. The overall annual burden for the recordkeeping and reporting 
requirements is 4,202 hours. It is expected that approximately 125 
respondents will be affected, therefore, the annual recordkeeping and 
reporting burden averages 33 hours per respondent. This time is 
necessary to collect data, submit notifications and certifications to 
waste treaters and disposers, and to maintain records of this 
information. The annual cost burden for this rule is approximately 
$177,045. Of this amount, it is estimated that facilities will incur 
annual operation and maintainence capital costs of approximately 
$8,375.
    The additional burden associated with the UIC Program, explained in 
ICR 0370.14, is as follows. The estimated annual reporting burden 
averages 3845 hours per respondent (i.e., inclusive of incremental 
reporting burdens associated with all affected Class I facilities and 
Primacy States). The average incremental annual reporting and 
recordkeeping burdens are about 4,442 hours per each affected Class I 
nonhazardous facility and about 2,700 hours per each affected Class I 
hazardous facility. For efforts associated with implementing the rule 
amendments, the annual incremental State burden equals about 22 hours 
for each Class I respondent.
    Burden means the total time, effort, or financial resources 
expended by persons to generate, maintain, retain, or disclose or 
provide information to or for a Federal agency. This includes the time 
needed to review instructions; develop, acquire, install, and utilize 
technology and systems for the purposes of collecting, validating, and 
verifying information, processing and maintaining information, and 
disclosing and providing information; adjust the existing ways to 
comply with any previously applicable instructions and requirements; 
train personnel to be able to respond to a collection of information; 
search data sources; complete and review the collection of information; 
and transmit or otherwise disclose the information.
    An Agency may not conduct or sponsor, and a person is not required 
to respond to a collection of information unless it displays a 
currently valid OMB control number.
    Send comments on the Agency's need for this information, the 
accuracy of the provided burden estimates, and any suggested methods 
for minimizing respondent burden, including through the use of 
automated collection of techniques to the Director, OPPE Regulatory 
Information Division; U.S. Environmental Protection Agency (2136); 401 
M St., S.W.; Washington, DC 20460; and to the Office of Information and 
Regulatory Affairs, Office of Management and Budget, 725 17th St., 
N.W., Washington, D.C. 20503, marked ``Attention: Desk Officer for 
EPA.'' Include the ICR numbers in any correspondence.

X. Unfunded Mandates Reform Act

    Under Section 202 of the Unfunded Mandates Reform Act of 1995, 
signed into law on March 22, 1995, EPA must prepare a statement to 
accompany any rule where the estimated costs to State, local, or tribal 
governments in the aggregate, or to the private sector, will be $100 
million or more in any one year. Under Section 205, EPA must select the 
most cost-effective and least burdensome alternative that achieves the 
objective of the rule and is consistent with statutory requirements. 
Section 203 requires EPA to establish a plan for informing and advising 
any small governments that may be significantly impacted by the rule.
    EPA has completed an analysis of the costs and benefits from the 
LDR Phase III rule and has determined that this rule does not include a 
Federal mandate that may result in estimated costs of $100 million or 
more to either State, local or tribal governments in the aggregate. As 
stated above, the private sector may incur costs exceeding $100 million 
per year depending upon the option chosen in the final rulemaking. EPA 
has fulfilled the requirement for analysis under the Unfunded Mandates 
Reform Act, and results of this analysis have been included in the 
background document ``Regulatory Impact Analysis of the Final Phase III 
Land Disposal Restrictions Rule,'' which was placed in the docket for 
today's rule.

    For the reasons set out in the preamble, title 40, chapter I of the 
Code of Federal Regulations is amended as follows:

PART 148--HAZARDOUS WASTE INJECTION RESTRICTIONS

    1. The authority citation for part 148 continues to read as 
follows:

    Authority: Secs. 3004, Resource Conservation and Recovery Act, 
42 U.S.C. 6901 et seq.

    2. Section 148.1 is amended by revising paragraphs (a), (b) and (d) 
to read as follows:


Sec. 148.1  Purpose, scope and applicability.

    (a) This part identifies wastes that are restricted from disposal 
into Class I wells and defines those circumstances under which a waste, 
otherwise prohibited from injection, may be injected.
    (b) The requirements of this part apply to owners or operators of 
Class I hazardous waste injection wells used to inject hazardous waste; 
and, owners or operators of Class I injection wells used to inject 
wastes which once exhibited a prohibited characteristic of hazardous 
waste identified in 40 CFR part 261, subpart C, at the point of 
generation, and no longer exhibit the characteristic at the point of 
injection.
* * * * *
    (d) Wastes that are only hazardous because they display a 
characteristic of ignitability, corrosivity, reactivity, or toxicity 
that are otherwise prohibited, are not prohibited:
    (1) If the wastes are disposed into a nonhazardous waste injection 
well defined under 40 CFR 144.6(a); and
    (2) Do not exhibit any prohibited characteristic of hazardous waste 
identified in 40 CFR part 261, subpart C, and either:
    (i) Do not contain any hazardous constituents identified in 40 CFR 
268.48 at levels greater than the 40 CFR 268.48 Universal Treatment 
Standard levels at the point of generation;
    (ii) Are de minimis in volume and hazardous constituent 
concentration levels, as defined in 40 CFR 268.1(e)(4)(ii). 
(Recordkeeping requirements for this alternative are found at 40 CFR 
268.9(d)(4).); or
    (iii)(A) The facility removes an equivalent mass of hazardous

[[Page 15597]]
constituents as would be removed by treating the characteristic 
hazardous wastestream pursuant to the treatment standards in 40 CFR 
268.48. This mass reduction can come from:
    (1) Treating nonhazardous portions of the injectate;
    (2) Recycling before ultimate injection; or
    (3) Engaging in pollution prevention practices (such as equipment 
or technology modifications, substitution of raw materials, and 
improvements in housekeeping, maintenance, training, or inventory 
control).
    (B) The compliance alternative in paragraph (d)(2)(iii)(A) of this 
section is demonstrated by comparing the injected baseline (determined 
by multiplying the volume/day of characteristically hazardous waste 
generated and injected) times the concentration of hazardous 
constituents before the treatment/recycling/pollution prevention 
measure, with the mass allowance obtained by multiplying the volume/day 
of a hazardous constituent generated and injected times the universal 
treatment standard for that constituent. The baseline cannot include 
practices initiated before the year 1990. (Recordkeeping requirements 
for this alternative are found at 40 CFR 268.9(d)(3).)
    3. Section 148.3 is revised to read as follows:


Sec. 148.3  Dilution prohibited as a substitute for treatment.

    (a) The provisions of 40 CFR 268.3 shall apply to owners or 
operators of Class I wells used to inject a waste which is hazardous at 
the point of generation whether or not the waste is hazardous at the 
point of injection.
    (b) Owners or operators of Class I nonhazardous waste injection 
wells which inject waste formerly exhibiting a hazardous characteristic 
which has been removed by dilution, may address underlying hazardous 
constituents by treating the hazardous waste, obtaining an exemption 
pursuant to a petition filed under Sec. 148.20, or complying with the 
provisions set forth in 40 CFR 268.9.
    4. Section 148.4 is revised to read as follows:


Sec. 148.4  Procedures for case-by-case extensions to an effective 
date.

    The owner or operator of a Class I hazardous or nonhazardous waste 
injection well may submit an application to the Administrator for an 
extension of the effective date of any applicable prohibition 
established under subpart B of this part according to the procedures of 
40 CFR 268.5.

text to read as follows:


Sec. 148.20  Petitions to allow injection of a waste prohibited under 
subpart B.

    (a) Any person seeking an exemption from a prohibition under 
subpart B of this part for the injection of a restricted hazardous 
waste, including a hazardous waste exhibiting a characteristic and 
containing underlying hazardous constituents at the point of 
generation, but no longer exhibiting a characteristic when injected 
into a Class I injection well or wells, shall submit a petition to the 
Director demonstrating that, to a reasonable degree of certainty, there 
will be no migration of hazardous constituents from the injection zone 
for as long as the waste remains hazardous. This demonstration requires 
a showing that:

flow of wastewater into the facility's headworks on an annual basis, or 
with a combined annualized average concentration not exceeding one part 
per million in the headworks of the facility's wastewater treatment or 
pretreatment facility; or
    (ii) Decharacterized wastes which are injected into Class I 
nonhazardous wells which wastes combined volume is less than one per 
cent of the total flow at the wellhead on an annualized basis, is no 
greater than 10,000 gallons per day, and in which any underlying 
hazardous constituents in the characteristic wastes are present at the 
point of generation at levels less than ten times the treatment 
standards found at Sec. 268.48.

    9. Section 268.2 is amended by revising paragraphs (f) and (i), and 
by adding paragraphs (j), (k), and (l) to read as follows:


Sec. 268.2  Definitions applicable in this part.

* * * * *
    (f) Wastewaters are wastes that contain less than 1% by weight 
total organic carbon (TOC) and less than 1% by weight total suspended 
solids (TSS).
* * * * *
    (i) Underlying hazardous constituent means any constituent listed 
in Sec. 268.48, Table UTS--Universal Treatment Standards, except 
fluoride, vanadium, and zinc, which can reasonably be expected to be 
present at the point of generation of the hazardous waste, at a 
concentration above the constituent-specific UTS treatment standards.
    (j) Inorganic metal-bearing waste is one for which EPA has 
established treatment standards for metal hazardous constituents, and 
which does not otherwise contain significant organic or cyanide content 
as described in Sec. 268.3(b)(1), and is specifically listed in

    10. Section 268.3 is revised to read as follows:


Sec. 268.3  Dilution prohibited as a substitute for treatment.

    (a) No generator, transporter, handler, or owner or operator of a 
treatment, storage, or disposal facility shall in any way dilute a 
restricted waste or the residual from treatment of a restricted waste 
as a substitute for adequate treatment to achieve compliance with 
subpart D of this part, to circumvent the effective date of a 
prohibition in subpart C of this part, to otherwise avoid a prohibition 
in subpart C of this part, or to circumvent a land disposal prohibition 
imposed by RCRA section 3004.
    (b) Dilution of wastes that are hazardous only because they exhibit 
a hazardous characteristic in a treatment system which treats wastes 
subsequently discharged to a water of the United States pursuant to a 
permit issued under section 402 of the Clean Water Act (CWA), or which 
treats wastes for the purposes of pretreatment requirements under 
section 307 of the CWA, or zero discharge systems with wastewater 
treatment equivalent to these systems, is not impermissible dilution, 
so long as the Sec. 268.48 universal treatment standards are met at the 
point of discharge, or at a prior point of compliance specified under a 
CWA permit, for all underlying hazardous constituents reasonably 
expected to be present at the point of generation of the hazardous 
waste.
    (c) Combustion of the hazardous waste codes listed in Appendix XI 
of this part is prohibited, unless the waste, at the point of 
generation, or after any bona fide treatment such as cyanide 
destruction prior to combustion, can be demonstrated to comply with one 
or more of the following criteria (unless otherwise specifically 
prohibited from combustion):
    (1) the waste contains hazardous organic constituents or cyanide at 
levels exceeding the constituent-specific treatment standard found in 
Sec. 268.48;
    (2) The waste consists of organic, debris-like materials (e.g., 
wood, paper, plastic, or cloth) contaminated with an inorganic metal-
bearing hazardous waste;
    (3) The waste, at point of generation, has reasonable heating value 
such as greater than or equal to 5000 BTU per pound;
    (4) The waste is co-generated with wastes for which combustion is a 
required method of treatment;
    (5) The waste is subject to Federal and/or State requirements 
necessitating reduction of organics (including biological agents); or

paragraph (a) introductory text, paragraphs (a)(1)(ii), (a)(2)(i)(B), 
(a)(3)(ii), (b)(4)(ii), (b)(5)(iv), by removing ``268.45';'' at the end 
of paragraph (a)(1)(iv) and adding ``268.45'; and'' in its place, by 
removing ``; and,'' at the end of paragraph (a)(1)(v) and adding a 
period in its place, by removing paragraph (a)(1)(vi), and by adding 
paragraph (b)(5)(v) to read as follows:

Sec. 268.8  [Removed and reserved]

    12. Section 268.8 is removed and reserved.
    13. Section 268.9 is amended by revising paragraphs (a), (d) 
introductory text, (d)(1)(i), and (d)(1)(ii), and by adding paragraphs 
(d)(3), (e), (f), and (g) to read as follows:


Sec. 268.9  Special rules regarding wastes that exhibit a 
characteristic.

    (a) The initial generator of a solid waste must determine each EPA 
Hazardous Waste Number (waste code) applicable to the waste in order to 
determine the applicable treatment standards under subpart D of this 
part. For purposes of this part 268, the waste will carry the waste 
code for any applicable listing under 40 CFR part 261, subpart D. In 
addition, the waste will carry one or more of the waste codes under 40 
CFR part 261, subpart C, where the waste exhibits a characteristic, 
except in the case when the treatment standard for the waste code 
listed in 40 CFR part 261, subpart D operates in lieu of the standard 
for the waste code under 40 CFR part 261, subpart C, as specified in 
paragraph (b) of this section. If the generator determines that his 
waste displays a hazardous characteristic (and the waste is not a 
D004--D011 waste, a High TOC D001, or is not treated by CMBST, or RORGS 
of Sec. 268.42, Table 1), the generator must determine what underlying 
hazardous constituents (as defined in Sec. 268.2), are reasonably 
expected to be present above the universal treatment standards found in 
Sec. 268.48.
* * * * *
    (d) Wastes that exhibit a characteristic are also subject to 
Sec. 268.7 requirements, except that once the waste is no longer 
hazardous, a one-time notification and certification must be placed in 
the generators or treaters files and sent to the EPA region or 
authorized state, except for those facilities discussed in paragraph 
(f) of this section. The notification and certification that is placed 
in the generators or treaters files must be updated if the process or 
operation generating the waste changes and/or if the Subtitle D 
facility receiving the waste changes. However, the generator or treater 
need only notify the EPA region or an authorized state on an annual 
basis if such changes occur. Such notification and certification should 
be sent to the EPA region or authorized state by the end of the 
calendar year, but no later than December 31.
    (1) * * *
    (i) For characteristic wastes other than those managed on site in a 
wastewater treatment system subject to the Clean Water Act (CWA), zero-
dischargers engaged in CWA-equivalent treatment, or Class I 
nonhazardous injection wells, the name and address of the Subtitle D 
facility receiving the waste shipment; and
    (ii) For all characteristic wastes, a description of the waste as 
initially generated, including the applicable EPA Hazardous Waste 
Number(s), treatability group(s), and underlying hazardous 
constituents.
* * * * *
    (3) For characteristic wastes whose ultimate disposal will be into 
a Class I nonhazardous injection well, and compliance with the 
treatment standards found in Sec. 268.48 for underlying hazardous 
constituents is achieved through pollution prevention that meets the 
criteria set out at 40 CFR 148.1(d), the following information must 
also be included:
    (i) A description of the pollution prevention mechanism and when it 
was implemented if already complete;
    (ii) The mass of each underlying hazardous constituent before 
pollution prevention;
    (iii) The mass of each underlying hazardous constituent that must 
be removed, adjusted to reflect variations in mass due to normal 
operating conditions; and
    (iv) The mass reduction of each underlying hazardous constituent 
that is achieved.
    (e) For decharacterized wastes managed on-site in a wastewater 
treatment system subject to the Clean Water Act (CWA) or zero-
dischargers engaged in CWA-equivalent treatment, compliance with the 
treatment standards found at Sec. 268.48 must be monitored quarterly, 
unless the treatment is aggressive biological treatment, in which case 
compliance must be monitored annually. Monitoring results must be kept 
in on-site files for 5 years.
    (f) For decharacterized wastes managed on-site in a wastewater 
treatment system subject to the Clean Water Act (CWA) for which all 
underlying hazardous constituents (as defined in Sec. 268.2), are 
addressed by a CWA permit, this compliance must be documented and this 
documentation must be kept in on-site files.
    (g) For characteristic wastes whose ultimate disposal will be into 
a Class I nonhazardous injection well which qualifies for the de 
minimis exclusion described in Sec. 268.1, information supporting that 
qualification must be kept in on-site files.


Secs. 268.10-268.12  [Removed and Reserved]

    14. Sections 268.10 through 268.12 are removed and reserved.

equivalent, and Class I nonhazardous injection well treatment 
standards; spent aluminum potliners; and carbamate wastes.

    (a) On July 8, 1996, the wastes specified in 40 CFR 261.32 as EPA 
Hazardous Waste numbers K156-K161; and in 40 CFR 261.33 as EPA 
Hazardous Waste numbers P127, P128, P185, P188-P192, P194, P196-P199, 
P201-P205, U271, U277-U280, U364-U367, U372, U373, U375-U379, U381-
U387, U389-U396, U400-U404, U407, and U409-U411 are prohibited from 
land disposal. In addition, soil and debris contaminated with these 
wastes are prohibited from land disposal.
    (b) On July 8, 1996 the wastes identified in 40 CFR 261.23 as D003 
that are managed in systems other than those whose discharge is 
regulated under the Clean Water Act (CWA), or that inject in Class I 
deep wells regulated under the Safe Drinking Water Act (SDWA), or that 
are zero dischargers that engage in CWA-equivalent treatment before 
ultimate land disposal, are prohibited from land disposal. This 
prohibition does not apply to unexploded ordnance and other explosive 
devices which have been the subject of an emergency response (such D003 
wastes are prohibited unless they meet the treatment standard of DEACT 
before land disposal (see Sec. 268.40)).
    (c) On July 8, 1996, the wastes specified in 40 CFR 261.32 as EPA 
Hazardous Waste number K088 are prohibited from land disposal. In 
addition, soil and debris contaminated with these wastes are prohibited 
from land disposal.
    (d) On April 8, 1998, decharacterized wastes managed in surface 
impoundments whose discharge is regulated under the Clean Water Act 
(CWA), or decharacterized wastes managed by zero dischargers in surface 
impoundments or tanks that engage in CWA-equivalent treatment before 
ultimate land disposal are prohibited from land disposal. The following 
are exceptions to this requirement:
    (1) Surface impoundments which are permitted under subtitle C of 
RCRA;
    (2) Storm water impoundments as defined in Sec. 268.2;
    
[[Page 15600]]

    (3) Surface impoundments which are part of facilities in the pulp, 
paper, and paperboard industrial category.
    (e) On April 8, 1998, Radioactive wastes mixed with K088, K156-
K161, P127, P128, P185, P188-P192, P194, P196-P199, P201-P205, U271, 
U277-U280, U364-U367, U372, U373, U375-U379, U381-U387, U389-U396, 
U400-U404, and U407, U409-U411 are also prohibited from land disposal. 
In addition, soil and debris contaminated with these radioactive mixed 
wastes are prohibited from land disposal.
    (f) Between July 8, 1996 and April 8, 1998, the wastes included in 
paragraphs (a), (b), (c), and (e) of this section may be disposed in a 
landfill or surface impoundment, only if such unit is in compliance 
with the requirements specified in Sec. 268.5(h)(2).
    (g) The requirements of paragraphs (a), (b), (c), (d), and (e) of 
this section do not apply if:
    (1) The wastes meet the applicable treatment standards specified in 
Subpart D of this part;
    (2) Persons have been granted an exemption from a prohibition 
pursuant to a petition under Sec. 268.6, with respect to those wastes 
and units covered by the petition;
    (3) The wastes meet the applicable alternate treatment standards 
established pursuant to a petition granted under Sec. 268.44;
    (4) Persons have been granted an extension to the effective date of 
a prohibition pursuant to Sec. 268.5, with respect to these wastes 
covered by the extension.
    (h) To determine whether a hazardous waste identified in this 
section exceeds the applicable treatment standards specified in 
Sec. 268.40, the initial generator must test a sample of the waste 
extract or the entire waste, depending on whether the treatment 
standards are expressed as concentrations in the waste extract or the 
waste, or the generator may use knowledge of the waste. If the waste 
contains constituents in excess of the applicable Subpart D levels, the 
waste is prohibited from land disposal, and all requirements of this 
part 268 are applicable, except as otherwise specified.
    16. Section 268.40 is amended by revising paragraph (e) and the 
table at the end of Sec. 268.40 to read as follows:


Sec. 268.40  Applicability of treatment standards.

* * * * *
    (e) For characteristic wastes (D001-D043) that are subject to 
treatment standards in the following table ``Treatment Standards for 
Hazardous Wastes,'' all underlying hazardous constituents (as defined 
in Sec. 268.2(i)) must meet Universal Treatment Standards, found in 
Sec. 268.48, ``Table UTS,'' prior to land disposal.
    (1) When these wastes are managed in wastewater treatment systems 
regulated by the Clean Water Act (CWA), compliance with the treatment 
standards must be achieved no later than ``end-of-pipe'' as defined in 
Sec. 268.2(k); or
    (2) When these wastes are managed in CWA-equivalent treatment 
systems and tank-based systems that discharge onto the land, compliance 
with the treatment standards must be achieved no later than the point 
the wastewater is released to the land (e.g., spray irrigation, 
discharge to dry river beds, placed into evaporation ponds); or
    (3) When these wastes are managed in Class I nonhazardous injection 
wells, compliance with the treatment standards must be achieved no 
later than the well head; or
    (4) For all other, compliance with the treatment standard must be 
met prior to land disposal as defined in Sec. 268.2(c).

Notes to Table:                                                                                                                                                                                 
1 The waste descriptions provided in this table do not replace waste descriptions in 40 CFR part 261. Descriptions of Treatment/Regulatory Subcategories are provided, as needed, to distinguish
  betweenapplicability of different standards.                                                                                                                                                  
2 CAS means Chemical Abstract Services. When the waste code and/or regulated constituents are described as a combination of a chemical with it's salts and/or esters, the CAS number is given   
  for the parent compound only.                                                                                                                                                                 
3 Concentration standards for wastewaters are expressed in mg/l and are based on analysis of composite samples.                                                                                 
4 All treatment standards expressed as a Technology Code or combination of Technology Codes are explained in detail in 40 CFR 268.42 Table 1--Technology Codes and Descriptions of Technology-  
  Based Standards.                                                                                                                                                                              
5 Except for Metals (EP or TCLP) and Cyanides (Total and Amenable) the nonwastewater treatment standards expressed as a concentration were established, in part, based upon incineration in     
  units operated in accordance with the technical requirements of 40 CFR Part 264, Subpart O, or Part 265, Subpart O, or based upon combustion in fuel substitution units operating in          
  accordance with applicable technical requirements. A facility may comply with these treatment standards according to provisions in 40 CFR 268.40(d). All concentration standards for          
  nonwastewaters are based on analysis of grab samples.                                                                                                                                         
6 Where an alternate treatment standard or set of alternate standards has been indicated, a facility may comply with this alternate standard, but only for the Treatment/Regulatory Subcategory 
  or physical form (i.e., wastewater and/or nonwastewater) specified for that alternate standard.                                                                                               
7 Both Cyanides (Total) and Cyanides (Amenable) for nonwastewaters are to be analyzed using Method 9010 or 9012, found in ``Test Methods for Evaluating Solid Waste, Physical/Chemical          
  Methods'', EPA Publication SW-846, as incorporated by reference in 40 CFR 260.11, with a sample size of 10 grams and a distillation time of one hour and 15 minutes.                          
8 As an alternative to these standards, the underlying hazardous constituents in the waste must meet a CWA limitation, which can include a toxic pollutant indicator for the constituent;       
  Pretreatment Standards for Existing Sources; Pretreatment Standards for New Sources; local limitations based upon a pass-through determination; or a Fundamentally Different Factors variance 
  under 40 CFR 125.30-125.32.

    18. Section 268.44 is amended by revising paragraph (a) to read as 
follows:


Sec. 268.44  Variance from a treatment standard.

    (a) Where the treatment standard is expressed as a concentration in 
a waste or waste extract and a waste cannot be treated to the specified 
level, or where the treatment technology is not appropriate to the 
waste, the generator or treatment facility may petition the 
Administrator for a variance from the treatment standard. The 
petitioner must demonstrate that because the physical or chemical 
properties of the waste differs significantly from wastes analyzed in 
developing the treatment standard, the waste cannot be treated to

\1\ CAS means Chemical Abstract Services. When the waste code and/or regulated constituents are described as a  
  combination of a chemical with it's salts and/or esters, the CAS number is given for the parent compound only.
\2\ Concentration standards for wastewaters are expressed in mg/l and are based on analysis of composite        
  samples.                                                                                                      
\3\ Except for Metals (EP or TCLP) and Cyanides (Total and Amenable) the nonwastewater treatment standards      
  expressed as a concentration were established, in part, based upon incineration in units operated in          
  accordance with the technical requirements of 40 CFR part 264, subpart O, or 40 CFR part 265, subpart O, or   
  based upon combustion in fuel substitution units operating in accordance with applicable technical            
  requirements. A facility may comply with these treatment standards according to provisions in 40 CFR          
  268.40(d). All concentration standards for nonwastewaters are based on analysis of grab samples.              
\4\ Both Cyanides (Total) and Cyanides (Amenable) for nonwastewaters are to be analyzed using Method 9010 or
