AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule; technical correction.

SUMMARY: This rule corrects and clarifies five related rules the EPA published on May 12, 1997, May 26, 1998, August 31, 1998, September 4, 1998, and September 24, 1998. On May 12, 1997, EPA published regulations promulgating Land Disposal Restrictions (LDR) treatment standards for wood preserving wastes, as well as reducing the paperwork burden for complying with LDRs. On May 26, 1998, EPA published regulations promulgating LDR treatment standards for metal-bearing wastes, as well as amending the LDR treatment standards for soil contaminated with hazardous waste, and amending the definition of which secondary materials from mineral processing are considered to be wastes subject to the LDRs. On August 31, 1998, EPA published an administrative stay of the metal-bearing waste treatment standards as they apply to zinc micronutrient fertilizers. On September 4, 1998, EPA published an emergency revision of the LDR treatment standards for hazardous wastes from the production of carbamate wastes. On September 24, 1998, EPA published revised treatment standards for spent aluminum potliners from primary aluminum production. Today's rule makes technical corrections and clarifications to these final regulations.

EFFECTIVE DATE: This rule is effective on May 11, 1999.

SUPPLEMENTARY INFORMATION:

I. Reasons and Basis for Today's Amendments

The Agency has received several comments from the regulated community requesting clarification and correction of certain aspects of five rules all promulgating and revising Phase IV of the LDRs. These are: the May 12, 1997 LDR Phase IV final rule (the so-called ``Mini'' Rule, 62 FR 25998), the May 26, 1998 LDR Phase IV final rule (63 FR 28556), the August 31, 1998 administrative stay of the May 26, 1998 rule's applicability to certain zinc micronutrient fertilizers (63 FR 46332), the September 4, 1998 emergency revisions to the treatment standards for carbamate production wastes (63 FR 172), and the September 24, 1998 revisions to the treatment standards for spent aluminum potliners (63 FR 51254). Today's preamble discussion amendments make clarifications and technical corrections where appropriate in light of the comments received.

II. Clarification of the May 12, 1997 LDR Phase IV ``Mini Rule''

On May 12, 1997, EPA published regulations promulgating certain aspects of the original LDR Phase IV proposal (60 FR 11702, March 2, 1995), including a discussion clarifying point of generation of hazardous wastes (see 60 FR 26006-7, May 12, 1997). That discussion may have been confusing with regard to the status of sludge from high-TOC ignitable waste treated in entirely tank-based NPDES or POTW discharge systems. To clarify, EPA's position is that where wastes are managed in NPDES or POTW discharge systems that are entirely tank-based, the wastes are not destined for land disposal and, therefore, neither the LDR disposal prohibitions nor the treatment standards (or attendant dilution prohibition) apply. Conversely, where an NPDES or POTW discharge system includes a land-based unit (i.e., a surface impoundment), wastes managed in the system are considered to be destined for land disposal, and the LDR regulations do apply. See 61 FR 15566 at 15570 (April 8, 1996), 53 FR 31136 at 31149 (August 17, 1988).

Accordingly, the management of a high-TOC ignitable waste in an entirely tank-based NPDES or POTW discharge system--whether inadvertent or not--would trigger no LDR requirements. Sludge subsequently removed from the tanks would be considered newly-generated waste (for LDR purposes) regardless of any changes in treatability group, and LDR requirements would apply with respect to its management only if the sludge itself is hazardous waste when removed. If the sludge is a hazardous waste, the LDR treatment standard that would apply would depend on the hazardous waste code and treatability group (or subcategory) of the sludge itself.

III. Amendments to and Clarifications of the May 26, 1998 LDR Phase IV Final Rule

Several errors exist in the regulatory language of the LDR Phase IV final rule, which we are correcting with today's rule. We are also making several clarifications to the preamble of the LDR Phase IV final rule.

A. Corrections to the LDR Phase IV Final Rule

1. Section 261.2(e)(1)(iii)

Section 261.2(e) identifies materials that are not solid wastes when recycled. The rule added an amendment to Sec. 261.2(e)(1)(iii), which amendment applies only to secondary materials generated and reclaimed by the primary mineral processing industry. The rule inadvertently deleted language in Sec. 261.2(e)(1)(iii) that applies to other industrial sectors recycling secondary materials. The Agency did not intend to eliminate the long-standing regulatory exclusions for other industrial sectors, and indeed effectively stated that the provision was not being amended for other industry sectors, see 63 FR at 28583-584. We are therefore restoring the omitted text in this section. 2. Section 261.4

The Hazardous Waste Combustion Revised Standards published on June 19, 1998 (63 FR 33782) added a paragraph to Sec. 261.4(a)(16), which inadvertently changed what was promulgated in the LDR Phase IV final rule. To avoid confusion, we are redesignating the language promulgated in Sec. 261.4(a)(16) in the LDR Phase IV final rule as Sec. 261.4(a)(17).

Section 261.4(a)(17) (as renumbered in this rule) identifies certain mineral processing secondary materials as subject to a conditional exclusion from subtitle C regulation as follows:

Secondary materials * * * generated within the primary mineral processing industry from which minerals, acids, cyanide, water or other values are recovered by mineral processing.

As noted throughout the preamble, however, the same mineral processing secondary materials are also recovered

[Page 25409]in beneficiation operations. See, e.g., 63 FR at 28578. EPA did not intend to restrict the scope of the conditional exclusion to recovery only in mineral processing operations. Id. Consequently, EPA is amending Sec. 261.4(a)(17) to indicate that recovery of these secondary materials may occur in either mineral processing or beneficiation operations.

This same amendment is being made to Sec. 261.4(b)(7)(iii), which sets out the conditions under which wastes from the co-processing of normal feedstock with mineral processing secondary materials remains exempt from subtitle C regulation under the Bevill Amendment. In relevant part, the rule states:

A residue derived from co-processing mineral processing secondary materials with normal beneficiation raw materials remains excluded under paragraph (b) * * * if the owner or operator:

  (A) Processes at least 50 percent by weight normal beneficiation raw materials;

The regulation inadvertently neglected to address the comparable situation when Bevill residues come from mineral processing rather than beneficiation operations. EPA clearly indicates in the preamble that the provisions of paragraph (b)(7)(ii) also apply to co-processing mineral processing secondary materials in beneficiation units. See 63 FR at 28595; see also 54 FR at 36614, 16619-620, 36629 (Sept. 1, 1989); 54 FR at 15324-325, 15341 (April 17, 1989) (prior rulemakings where EPA indicated that these conditions apply). Consequently, EPA is adding clarifying language to Sec. 261.4(b)(7)(iii) to affirm that both beneficiation and mineral processing operations are included. 3. Section 268.7

The tables in Sec. 268.7(a) and (b), entitled ``Generator Paperwork Requirements Table'' and ``Treatment Facility Paperwork Requirements Table,'' are now erroneously missing certain checkmarks, which we are reinstating in today's rule. The LDR Phase IV final rule also added a line eight to the ``Generator Paperwork Requirements Table,'' and a line five to the ``Treatment Facility Paperwork Requirements Table,'' both for contaminated soil, which inadvertently erased the previous lines eight and five. We are correcting this oversight by reinstating the missing lines as nine and six, respectively. 4. Section 268.9

The language in Sec. 268.9(d)(2) currently refers to language in Sec. 268.7(b)(5), which has been renumbered as Sec. 268.7(b)(4). Today's rule amends the language in Sec. 268.9 to correct this miscitation. For more clarification of LDR certifications and how they apply to soil, see the discussion in section B.6.c. below. 5. Section 268.40

Today's rule also amends the treatment standard table found in Sec. 268.40. The entry for P015 incorrectly describes this waste as ``beryllium dust''; the proper term is ``beryllium powder.'' Also, the entry for U408 gave the incorrect CAS number for 2,4,6-Tribromophenol. We are correcting these errors in today's rule. For other errors in the Sec. 268.40 table, see sections V. and VI. below.

B. Clarifications to the LDR Phase IV Final Rule

1. Effective Dates

The Agency has received a number of questions about the dates when various provisions of the LDR Phase IV final rule become effective. A memorandum explaining in further detail the effective dates of the LDR Phase IV final rule is available in the RCRA docket for the rule, and is also available on the internet at: http://www.epa.gov/epaoswer/ hazwaste/ldr/ldrmetal/memos/effectiv.pdf.

Part of the confusion over the compliance dates for the LDR Phase IV final rule resulted from EPA incorrectly referring to effective dates as ``compliance dates''. In the ``Effective Dates'' section in the preamble (see page 28556, middle column), the Agency lists four exceptions to the August 24, 1998 effective date for the rule. These exceptions are referred to as ``compliance dates'', when, in fact, they are effective dates.

Another point of clarification relates to the LDR Phase IV final rule amendments of the treatment standards for carbamate wastes, which were originally promulgated in the LDR Phase III final rule on April 8, 1996 (61 FR 15566). The LDR Phase IV amendments went into effect August 24, 1998. However, on September 4, 1998, the Agency changed the compliance dates for the LDR Phase IV carbamate treatment standards. If you have any questions related to compliance with the carbamate treatment standards, we direct you to the Emergency Revision of the Land Disposal Restrictions Treatment Standards for Listed Hazardous Wastes from Carbamate Production, which was published on September 4, 1998 (63 FR 172). 2. Waste as Fill

In the May 12, 1997 second supplemental proposed rule, EPA raised the issue of prohibiting the use of hazardous waste as fill material unless it was demonstrated to the Agency (or authorized State) that the use of the waste minimized threats to human health and the environment (see 62 FR 26061). The Agency did not finalize this issue in the LDR Phase IV final rule, but the proposal remains pending and awaiting EPA further action. 3. Cement Kiln Dust

EPA states at 63 FR at 28600/3 that:

The Agency is aware that both cement kiln[s] and aggregate kilns may both burn hazardous wast[e] fuels and that the dusts from air pollution control devices are often blended into final products. Under existing regulations, if these dusts resulting from burning listed hazardous waste fuels are blended into products that are used on the land, the product would be subject to RCRA's `derived from' rules. * * *''

The second sentence refers to a situation where the Bevill amendment does not apply to the residue from burning the hazardous waste derived fuel. The overall sense and intent of this section of the preamble remains that EPA wishes to consider cement kiln dust and dust from lightweight aggregate kilns (including dusts from kilns burning hazardous waste as fuels) in the same fashion because they are similar materials managed in similar manners. 4. D004 Treatment Standards

Some confusion also apparently exists as to whether the Universal Treatment Standards (UTS) apply to D004 arsenic wastes. In the preamble to the LDR Phase IV final rule, we state that the UTS apply to both wastewater and nonwastewater forms of the TC metal wastes. But a parenthetical then states that, for TC arsenic wastes, the UTS applies to the wastewater form only. The Agency unfortunately has caused confusion by this parenthetical language. The parenthetical only meant to explain that we were revising or replacing the standard solely for the nonwastewater form of arsenic in LDR Phase IV. We did not intend by the parenthetical to suggest that the wastewater form of arsenic had changed or been eliminated, or that the UTS do not apply. The existing standard for the wastewater form of arsenic was and remains the UTS. Therefore, the UTS have and will continue to apply to D004 arsenic wastes in both forms. 5. TC Metal Standards and Mixed Wastes

In the preamble to the final rule, EPA refers to characteristic metal mixed wastes that were previously stabilized to meet the then- existing LDR

[Page 25410]requirements and that are now being stored prior to disposal. We indicate that these mixed wastes do not have to be re-treated to meet the revised treatment standards prior to disposal (63 FR 28575-28576). Mixed wastes are those that are both radioactive and hazardous. Although we believe that the preamble is clear, EPA has received a number of inquiries on this point. The Agency wishes to reiterate that, for the reasons explained in the LDR Phase IV preamble, if mixed wastes that are characteristically hazardous for metals were treated via stabilization to the old treatment standards before the effective date of the LDR Phase IV rule, these wastes do not need to be re-treated to meet the new treatment standards even if land disposal of the waste occurs after the effective date of the LDR Phase IV rule. Wastes previously treated by methods other than stabilization will have to be re-treated, as indicated clearly in the LDR Phase IV preamble, unless a site-specific variance is granted. Please note that the preamble further indicates EPA's amenability to grant such variances where, for example, there is risk of re-exposure to radiation. See 63 FR at 28576. 6. Soil Issues

EPA has received numerous questions about the alternative soil treatment standards. Two important questions and their answers appear below. Other questions will be handled through regular information channels, such as the RCRA Hotline at 1-800-424-9346. We also wish to remind readers generally that before receiving authorization for the soil treatment standards, states authorized for other portions of the LDR program may, for contaminated soil, use state waivers or other state authorities to waive the duty to comply with the LDR treatment standards for pure hazardous waste and allow, instead, compliance with the soil treatment standards. This is discussed more fully in the guidance memorandum mentioned above on LDR Phase IV rule effective dates.

a. What are the certification requirements for decharacterized soil? The certification requirements for decharacterized soil are similar to the requirements for decharacterized wastes. The certification language found in Sec. 268.7(b)(4) is to be used if underlying hazardous constituents in decharacterized soil have been treated, either to meet the 90% reduction or the ten times UTS provisions in the soil treatment standards. If underlying hazardous constituents in decharacterized soil have not been treated and are above the 10 X UTS soil standard, the soil still requires treatment. In this case, the revised certification language found in Sec. 268.7(b)(4)(iv) must be used instead. See 63 FR at 28620.

b. If constituents of concern in a hazardous contaminated soil have a specified method of treatment, can a facility still use the alternative soil treatment standards? In interpreting the alternative soil treatment standards found at Sec. 268.49(c)(3), questions have arisen, particularly with respect to: (1) use of soil treatment standards where the only constituents of concern are nonanalyzable, and (2) situations in which both analyzable and non-analyzable constituents are present. The table below details the appropriate implementation of the language in Sec. 268.49(c)(3), based on language from the preamble to the proposed and final rules with respect to contaminated soils containing both analyzable and nonanalyzable constituents. Readers should note that the following information only applies to constituents of concern present in a hazardous contaminated soil that must meet LDRs before land disposal.

Then soils contaminated with If these constituents are * And if these these constituents * *

Treat each concentration based constituent to limits in Sec.

numerical soil 268.40 and Sec. treatment levels. 268.48.

The preambles to both the final and proposed rules on contaminated soils make clear that EPA intended to allow treatment of analyzable constituents to serve as a surrogate for treating unanalyzable constituents only when the analyzable and unanalyzable constituents are both organics. The Phase IV preamble thus states that ``[i]n situations where contaminated soil contains both analyzable and nonanalyzable organic constituents, treating the analyzable constituents to meet the soil treatment standards is also reasonably expected to provide adequate treatment of nonanalyzable constituents.'' 63 FR at 28609 (emphasis added). This sentence indicates that it is reasonable to expect that treatment for analyzable organic constituents will be sufficiently effective for other organic, but nonanalyzable, constituents. See also, Phase II proposal, 58 FR at 48124 (col. 2) (Sept. 14, 1993) (likewise stating that the principle of treating only analyzable constituents applies only where analyzable and nonanalyzable constituents are both organics). We are accordingly amending the language of the rule so that it matches these preamble explanations.

This leaves unaddressed in the rule situations (which may or may not actually exist) where analyzable and unanalyzable hazardous constituents are not both organics. If the situation exists, it would not be reasonable to assume in all situations that organic treatment would serve as a surrogate for inorganic or metal treatment, or vice versa. Should the situation arise, EPA believes it should be addressed on a site-specific basis. The relevant factors to be considered include the types of hazardous constituents, their concentrations (for the analyzable constituents), and their amenability to common treatment.

c. What are nonanalyzable constituents? A nonanalyzable constituent is any constituent that does not have appropriate test methods or chemical standards to properly measure compliance with LDR concentration-based standards. A constituent is nonanalyzable under LDR regulation when (1) the appropriate Sec. 268.40 listing

[Page 25411]specifies a treatment technology, and (2) there is no concentration- based limit in the Sec. 268.48 UTS table. We note, simply for technical accuracy, that the Phase IV preamble (63 FR 28609, col. 2) refers in a parenthetical statement to nonanalyzable constituents as belonging only to P and U waste codes. That preamble parenthetical is not entirely correct. A limited number of organic nonanalyzable constituents are also regulated under K and F waste codes. This clarification does not affect implementation of Sec. 268.49(c)(3) in any way. 7. Intentional Mixing of Hazardous Waste With Soil or Debris

It is illegal to add soil or debris to a hazardous waste to change the waste's treatment classification to soil or debris and thereby to falsely claim eligibility for the alternative treatment standards for soil or debris. Put another way, addition of soil or debris to a hazardous waste does not change that waste into soil or debris for purposes of LDR treatment. As the Agency stated in the May 26, 1998 preamble, ``[A]ny deliberate mixing of prohibited hazardous waste with soil in order to change its treatment classification (i.e. from waste to contaminated soil) is illegal. Existing regulations concerning impermissible dilution already make this point.'' 63 FR at 28621. The conduct is impermissible dilution because it adds a diluting medium-- the soil--that neither contributes to effective treatment nor represents a bona fide substitute for adequate treatment. Id. EPA further made clear that this conduct subjects generators to civil and criminal penalties. 63 FR at 28621. In addition, the impermissibly diluted waste remains subject to the original treatment standard, ``so no benefit in terms of reduced treatment would occur.'' Id. EPA had earlier established the same principle for debris: ``[a]lthough EPA is classifying mixtures that are predominantly debris as debris, this does not mean that debris can be deliberately mixed with other wastes in order to change their treatment classification. Such mixing is impermissible dilution under Sec. 268.3 since it is a substitute for adequate treatment.'' 57 FR at 37224 (Aug. 18, 1992); see also 57 FR at 37243 (``if debris is intentionally mixed with contaminated soil or hazardous waste (e.g. after excavation), and the mixture is regulated as debris by the application of the mixture principle and subsequently immobilized, prohibited sham mixing has occurred'').

To ensure that there is no possibility of misunderstanding current law, EPA has decided to amend the definitions in Sec. 268.2 to reflect more directly the preamble language stating that intentional addition of soil or debris to hazardous waste is impermissible. Currently, the definitions of ``soil'' and ``debris'', respectively state that soil or debris is ``made up primarily of soil'' or ``primarily of debris.'' 40 CFR Sec. 268.2 (k) and (g). To remove any possible (albeit unfounded, given the existence of the dilution prohibition in Sec. 268.3 and the preamble language quoted above) confusion regarding the term ``primarily'' in the rules, EPA is incorporating language directly into the respective definitions that states that deliberate mixing of process waste to soil or debris that changes a treatment classification is impermissible dilution. These additions merely incorporate existing preamble text into regulations and do not establish any new principles. Thus, today's correction is at most an interpretive rule because EPA's existing interpretations are being codified as clarifications to the definitions of soil and debris and to the existing dilution prohibition in Sec. 268.3. Moreover, no new obligations are created because existing regulations--viz., the dilution prohibition in Sec. 268.3-- already make the conduct illegal. Whether the change is a technical correction or an interpretive rule, no opportunity for notice and comment is required. 5 U.S.C. Sec . 553(b). 8. Treatment Residuals and Point of Generation of a New Hazardous Waste for LDR Purposes

The Agency has received several inquiries concerning treating TC metal wastes and the potential for finding underlying hazardous constituents at levels above the UTS in the treatment residuals that were either not present in the waste prior to treatment or may have been present but only at levels below the UTS. This would occur, for example, if the treatment process is such that certain underlying hazardous constituents ( UHCs) might be more concentrated in treatment residuals than in the original waste.

Two illustrative scenarios are useful. The first involves a D007 chromium waste that is incinerated. Trace quantities of lead are present in the original waste, but at levels below the UTS (thus, lead is not a UHC under 40 CFR Sec. 268.2(i)). The resulting ash is no longer characteristic for chromium, but lead is now present at levels above the UTS. The second involves a D008 lead wastewater that contains no underlying hazardous constituents as generated, but that is treated with dithiocarbamate, a metal precipitating agent. Dithiocarbamate is also a hazardous constituent that appears on the list of potential UHCs in Sec. 268.48. The dithiocarbamate assists the stabilization of the lead but, after treatment, is present at levels above the UTS in the treatment residuals.

In both of these cases, the treatment residuals (ash and sludge) demonstrate that the original waste is decharacterized. Under Sec. 268.2(i), the only UHCs that must be treated and that must meet the Universal Treatment Standards (UTS) are those determined to be present above UTS levels in the original waste--either via testing or generator knowledge. Because the treatment process results in non- hazardous residuals, the treatment facility is not responsible for additional testing to determine if any different underlying hazardous constituents are added or created during the treatment process itself. Furthermore, only the original UHCs must meet the UTS.

However, if in either case the treatment residual is also characteristic by having constituents that are not only above the UTS level but also above the TC level, then the residual is a newly- generated hazardous waste for LDR purposes. This result is consistent with the definition of generator at Sec. 260.10: ``Generator means any person, by site, whose act or process produces hazardous waste identified or listed in part 261 * * * `` The result is also consistent with the key LDR principle that hazardous wastes must meet LDR treatment standards to minimize threats before the wastes are land disposed. See, e.g., Chemical Waste Management v. EPA, 976 F. 2d 2, 16- 18 (D.C. Cir. 1992) (treatment must include treatment for both characteristic property and for underlying hazardous constituents). For these reasons, the Agency regards generation of a new characteristic treatment residual as being a new point of generation for LDR purposes. This newly-formed hazardous waste would have to be treated to below the characteristic, and any underlying hazardous constituents would have to be treated to below their UTS levels.<SUP>1</SUP>

\1\ This analysis is consistent with the so-called change of treatability group principle first stated at 55 FR at 22661, col. 2 (June 1, 1990). That principle states that LDR prohibitions remain attached to the initial waste as long as the waste remains within the same treatability group (normally wastewater or nonwastewater). Thus, if a characteristic wastewater is treated and a non-wastewater sludge is generated from the treatment process, the prohibition for the wastewater does not automatically apply to the sludge. Id. The situation discussed in the text above, however, involves the status for this hypothetical sludge if it itself exhibits a characteristic of hazardous waste. EPA views such a characteristic sludge as being newly generated for LDR purposes.

[Page 25412]

Thus, in the first scenario above regarding a decharacterized waste with lead in the ash, if the lead is present in the ash at or above TC levels (i.e., a new D008 waste has been generated), the lead must be treated to UTS levels. Furthermore, the treater has generated the new hazardous waste for LDR purposes and is responsible for a new determination of UHCs that are present and that require treatment to UTS levels. The same is true in the second example if the dithiocarbamate treatment sludge is characteristic.

EPA notes further, however, that in determining whether a treatment process has generated a new hazardous waste for LDR purposes, the Agency looks to the entire treatment process, not to each component part. In general, as explained below, the determination of whether a new hazardous waste is generated--i.e., whether a new point of generation for LDR purposes is created--is made at the completion of the treatment process. Thus:

  (i) For residuals that are the end product of a one-step treatment process or the end product of a treatment train, the treater has the obligation to ensure only that the original UHCs meet UTS standards and that the treatment residuals are not themselves characteristic. If a treatment residual in this scenario does not meet the treatment standards for the original characteristic (i.e., when treatment is ineffective or incomplete) and requires further treatment, EPA does not consider the treatment residue to be newly generated for LDR purposes. Such a treatment residue, however, cannot be land disposed until it meets the treatment standard applicable to the original waste. This situation would normally involve re-treating the waste residuals on- site. Any UHCs added or created by the treatment process are not required to be treated because there is no new point of generation for LDR purposes. However, as noted above, if the treatment residuals are themselves characteristic due to a new property (for example, the formerly characteristic chromium D007 waste is now characteristic only for D008 lead), then the treater must make a new determination of the UHCs present--either through knowledge or additional testing. This is the same obligation that attaches to any generator of a hazardous waste.

  (ii) For treatment residuals that appear only at intermediate steps of a treatment train, there is no obligation to determine UHCs or to determine whether the residual is itself characteristic. Intermediate- step treatment residuals are not newly generated hazardous wastes for LDR purposes. Thus, even when an intermediate treatment residual is sent off-site for further treatment (such as incinerator ash going offsite for stabilization and landfilling), our current regulations at Sec. 268.7(b)(5) require only that the UHCs identified at the LDR point of generation be identified. There is no such requirement for any new UHCs that may be added or created during the preceding steps of the treatment process. 9. Clarification of Footnote 7 in Preamble

LDR Phase IV, as mentioned earlier, deals with the status of mineral processing materials under the RCRA definition of solid waste at Sec. 261.2. Footnote seven of the preamble to the LDR Phase IV final rule, as printed in the Federal Register, reads: ``EPA does note the potential anomaly that non-mineral processing secondary materials, at least for the moment, will be regulated in some cases stringently than those generated and reclaimed within the mineral processing industry.'' 63 FR at 28583 n. 7. This language reflects a printing error by the Office of Federal Register which erroneously omitted the word ``less'' before the word ``stringently'' in this sentence. The footnote thus should read: ``EPA does note the potential anomaly that non-mineral processing secondary materials, at least for the moment, will be regulated in some cases less stringently than those generated and reclaimed within the mineral processing industry.''

Of course, as EPA noted elsewhere in the rule, secondary materials within the mineral processing industry will be regulated in other instances less stringently than those from outside the industry (the principal example being characteristic spent materials being reclaimed). The main point, as expressed in the footnote, is that the new rules establish a separate solid waste classification scheme for the mineral processing industry that differs from the generic classification scheme set out in the remainder of Sec. 261.2.

IV. Amendment to the August 31, 1998 Stay for Certain Zinc Micronutrient Fertilizers

On August 31, 1998, EPA issued an administrative stay of the Phase IV rule as it applies to zinc micronutrient fertilizers that are produced from hazardous wastes exhibiting the toxicity characteristic. 63 FR 46332. Although EPA clearly stated throughout the rule that the administrative stay applied to ``zinc micronutrient fertilizers,'' the regulatory language codifying the stay mistakenly refers instead to ``zinc-containing fertilizers.'' See 63 FR 46334, to be codified at 40 CFR Sec. 268.40(i). There exists a remote possibility that there are fertilizers produced from toxicity characteristic hazardous wastes that do not utilize zinc as a micronutrient but otherwise contain zinc (possibly as a trace element without nutritive value). Since the administrative stay was not meant to apply to such (hypothetical) fertilizers, EPA is amending the regulatory language to cover only zinc micronutrient fertilizers, as intended.

V. Amendments to the September 4, 1998 Emergency Revision of the Treatment Standards for Listed Hazardous Wastes From Carbamate Production

The September 4, 1998 Emergency Revision of the LDR Treatment Standards for Listed Hazardous Wastes from Carbamate Production (63 FR 172) adds a paragraph (i) to Sec. 268.40, which inadvertently replaced the existing paragraph (i) added by the Land Disposal Restrictions final rule published on August 31, 1998 (staying LDR metal standards for zinc micronutrient fertilizers). Today's rule redesignates the current paragraph (i) as paragraph (j), and reinserts the paragraph (i) from the August 31, 1998 rule (as additionally amended in this correction notice, see section IV above). The September 4, 1998 rule also inadvertently changes footnotes eight and 11 to the table of treatment standards found in Sec. 268.40. The correct footnotes are reinstated in today's rule.

A more significant error in the September 4, 1998 Emergency Rule is the removal of footnote six for all constituents listed in the table of Universal Treatment Standards found in Sec. 268.48. In doing so, the rule mistakenly changes the status of certain carbamate constituents, which should not be underlying hazardous constituents until their newly revised treatment standards go into effect on March 4, 1999. By removing the footnote, these carbamate constituents are considered underlying hazardous constituents as of September 4, 1998, the effective date of the Emergency Rule. This was and is not the Agency's intention, and we are therefore reinstating the footnote with the correct date of March 4, 1999.

[Page 25413]

The treatment standards for K159 in the Table of Treatment Standards for Hazardous Wastes in Sec. 268.40 are currently incorrect. The standards were and should be those promulgated in the LDR Phase III final rule (61 FR 15566, April 8, 1996). However, those standards were inadvertently and mistakenly revised in a technical correction on February 19, 1997 (62 FR 7502). Today's rule reinstates the correct treatment standards for K159 in the Sec. 268.40 table.

Finally, today's rule also corrects: (1) the nonwastewater standard for oxamyl, which was listed incorrectly in the entry for P194; and (2) the CAS numbers for acetophenone and triethylamine, which were listed incorrectly in the entries for K156 and U404, respectively.

VI. Amendment to the September 24, 1998 Revision of the Treatment Standards for Spent Potliners From Primary Aluminum Reduction (K088)

On September 24, 1998 EPA promulgated revised LDR treatment standards for waste code K088. The rule changes the nonwastewater standard for arsenic in K088 from 5.0 mg/l TCLP to 26.1 mg/kg total, and also changes the nonwastewater standard for fluoride in K088 from 48 mg/l TCLP to NA. The wastewater standard for fluoride is unaffected by the rule. (That standard also is not affected by the court's rationale in Columbia Falls Aluminum Co. v. EPA, 139 F. 3d 914, 922-23 (D.C. Cir. 1998) because the standard for fluoride wastewaters does not involve the use of the TCLP.) Unfortunately, the final rule inadvertently omitted fluoride, and its treatment standards, from the entry for K088 in the table of treatment standards in Sec. 268.40. Because of this omission, the change to the nonwastewater standard for fluoride was not codified. Today we are restoring fluoride and its revised standards in the entry for K088 in the Sec. 268.40 table.

VII. Analysis Under Executive Order 12866, Executive Order 12875, Executive Order 12898, Executive Order 13045, Executive Order 13084, the Unfunded Mandates Reform Act of 1995, the Regulatory Flexibility Act, and the Paperwork Reduction Act

Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is not a ``significant regulatory action'' and is therefore not subject to review by the Office of Management and Budget. In addition, this action does not impose any enforceable duty, contain any unfunded mandate, or impose any significant or unique impact on small governments as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4). This rule also does not require prior consultation with State, local, and tribal government officials as specified by Executive Order 12875 (58 FR 58093, October 28, 1993) or Executive Order 13084 (63 FR 27655, May 10, 1998), or involve special consideration of environmental justice related issues as required by Executive Order 12898 (59 FR 7629, February 16, 1994). Because this action is not subject to notice-and-comment requirements under the Administrative Procedure Act or any other statute, it is not subject to the regulatory flexibility provisions of the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). This rule also is not subject to Executive Order 13045 (62 FR 19885, April 23, 1997) because EPA interprets E.O. 13045 as applying only to those regulatory actions that are based on health or safety risks, such that the analysis required under section 5-501 of the Order has the potential to influence the regulation. This rule is not subject to E.O. 13045 because it does not establish an environmental standard intended to mitigate health or safety risks. EPA's compliance with these statutes and Executive Orders for the underlying rule is discussed in the May 12, 1997, the May 26, 1998, the August 31, 1998, the September 4, 1998, and the September 24, 1998 Federal Register notices.

VIII. Submission to Congress and the General Accounting Office

The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. Section 808 allows the issuing agency to make a good cause finding that notice and public procedure is impracticable, unnecessary or contrary to the public interest. This determination must be supported by a brief statement. 5 U.S.C. 808(2). As stated previously, EPA has made such a good cause finding, including the reasons therefor, and established an effective date of May 11, 1999. EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. This action is not a ``major rule'' as defined by 5 U.S.C. 804(2).

IX. Immediate Effective Date

EPA is making this rule effective immediately. The rule adopts corrections which are purely technical in that they correct outright printing errors, or are manifestly inconsistent with the Agency's stated intent. Comment on such changes is unnecessary, within the meaning of 5 U.S.C. 553(b)(3)(B). For the same reasons, there is good cause to make the rule effective immediately pursuant to 5 U.S.C. 553(d)(3).
