Hazardous Waste Management System; Carbamate Production, 
Identification and Listing of Hazardous Waste; Land Disposal 
Restrictions; Authorization of State Hazardous Waste Programs; and 
CERCLA Hazardous Substance Designation and Reportable Quantities

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is amending its 
regulations to conform with the federal appeals court ruling in 
Dithiocarbamate Task Force v. EPA, 98 F.3d 1394 (D.C.Cir. 1996), that 
invalidated, in part, Agency regulations listing certain carbamate 
wastes as hazardous wastes under the Resource Conservation and Recovery 
Act (RCRA). These regulations pertain to hazardous waste management of 
carbamate industry wastes under RCRA, related rules affecting the list 
of hazardous substances under the Comprehensive Environmental Response, 
Compensation, and Liability Act (CERCLA), and regulations issued under 
state programs approved by the Administrator. Under the court's 
decision, and amended in today's rule, the vacated federal hazardous 
waste listings and regulatory requirements based on those listings are 
to be treated as though they have never been in effect. State 
regulations, which may be more stringent than federal rules, were not 
necessarily affected by the court's ruling.

EFFECTIVE DATE: This final rule takes effect on May 29, 1997.

ADDRESSES: Supporting materials are available for viewing in the RCRA

I. Background

    EPA lists wastes as hazardous wastes under section 3001 of RCRA, 42 
U.S.C. 6921. Once a waste is listed as hazardous it becomes subject to 
federal requirements for persons who generate, transport, treat, store, 
or dispose of such waste. Facilities that must meet the hazardous waste 
management requirements, including the need to obtain permits to 
operate, are commonly referred to as ``Subtitle C'' facilities. 
Subtitle C is Congress' original statutory designation for that part of 
RCRA that directs EPA to issue regulations for hazardous wastes.
    EPA standards and procedural regulations implementing Subtitle C 
are found generally at 40 CFR parts 260 through 272. Criteria and 
procedures for identifying and listing hazardous wastes are found at 40 
CFR part 261.
    General standards for generators of hazardous waste are found at 40 
CFR part 262. General standards for transporters of hazardous waste are 
found at 40 CFR part 263. General standards for owners and operators of 
hazardous waste treatment, storage and disposal facilities--including 
standards for obtaining permits--are found at 40 CFR part 264.
    Hazardous wastes are also subject to land disposal restrictions 
under 40 CFR part 268. EPA's authorizations for state hazardous waste 
programs are found at 40 CFR part 272. The requirements for obtaining 
these authorizations are found at 40 CFR part 271.
    In addition, hazardous wastes having the characteristics identified 
under, or listed pursuant to, RCRA section 3001 (except when suspended 
by Congress) become hazardous substances under section 101(14)(C) of 
CERCLA, 42 U.S.C. 9601(14)(C). A reportable quantity (RQ) of one pound 
for reporting environmental releases is established for each substance, 
as provided by section 102(b) of CERCLA, 42 U.S.C. 9602(b). The one-
pound statutory RQ applies until adjusted by regulations.
    On February 9, 1995, the EPA published in the Federal Register (60 
FR 7824) a rule listing as hazardous wastes under RCRA various wastes 
from four groups of carbamate compounds--carbamates, carbamoyl oximes, 
thiocarbamates and dithiocarbamates. These compounds, generally, are 
used as pesticides, herbicides and fungicides and in the rubber, wood 
and textile industries. This rule became effective on August 9, 1995.
    The rule added 58 specific carbamate compounds to the list of 
hazardous constituents upon which RCRA hazardous waste listing 
determinations are based. This list of constituents appears at Appendix 
VIII of 40 CFR part 261.
    These same 58 compounds were added to the list of commercial 
chemical products that are hazardous wastes only when they are 
discarded. This list is found at 40 CFR 261.33 and is divided into 
acutely hazardous wastes (``P-wastes'') and other toxic wastes (``U-
wastes''). P-wastes are listed in subsection 261.33(e) and U-wastes are 
listed in subsection 261.33(f). Eighteen of the carbamates were P-
wastes and 40 were U-wastes.
    The rule, also, added six hazardous wastes generated from the 
industrial production of the carbamate chemicals to 40 CFR 261.32. 
These are hazardous wastes from specific sources, or ``K-wastes.'' The 
carbamate wastes were given numbers K156, K157, K158, K159, K160, and 
K161. K159 and K160 applied to certain wastes from thiocarbamate 
production; K161 applied to a waste stream from dithiocarbamate 
production; K156, K157 and K158

[[Page 32975]]

applied to various waste streams from the production of carbamates, 
proper.
    As part of the listing rule, in accordance with Agency regulations, 
EPA also listed in Appendix VII of 40 CFR Part 261 the hazardous 
constituents upon which the production waste listings were based.
    The February 1995 rule also designated the carbamate wastes as 
CERCLA hazardous substances and added them to the hazardous substance 
list at 40 CFR 302.4 with statutory one-pound RQs, as required under 
CERCLA sections 101(14)(C) and 102.
    Subsequent to the February 1995 listing rule, EPA issued land 
disposal restriction (LDR) regulations for the carbamate wastes. These 
were issued on April 8, 1996 (61 FR 15663), and corrected June 28, 1996 
(61 FR 33683). The prohibition on land disposal of carbamate wastes was 
effective July 8, 1996 and the prohibition on radioactive waste mixed 
with newly listed or identified wastes, including soil and debris, is 
effective April 8, 1998. In addition, EPA amended its requirements for 
approval of state hazardous waste programs by adding the carbamate 
listing and LDR regulations to Tables 1 and 2 of 40 CFR part 271.1. 
(See 61 FR 15659-15660, April 8, 1996.) These tables list the 
regulations that establish the requirements and prohibitions applicable 
to state hazardous waste programs.
    On November 1, 1996, the United States Court of Appeals for the 
District of Columbia Circuit, in Dithiocarbamate Task Force v. EPA, 
ruled that EPA failed to follow proper rulemaking procedures in making 
some of the carbamate listing determinations and vacated them. 
Accordingly, EPA is removing from the Code of Federal Regulations those 
listings vacated by the court and all references to those listings. EPA 
notes that substantial portions of the decisions made in the carbamate 
listing rule remain in effect and are not changed by the court's 
ruling.
    The court vacated 24 U wastes, one K-waste (K160), and three of the 
K-wastes (K156, K157 and K158) only to the extent they apply to the 
chemical, 3-iodo-2-propynyl n-butylcarbamate (IPBC). Twenty-three of 
the vacated U wastes consisted of all the dithiocarbamates and 
thiocarbamates. The other vacated U waste was IPBC, a carbamate.

II. Amended Regulations

    Table 1 lists the 24 vacated U wastes that are removed from 40 CFR 
261.33(f).

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

    In 40 CFR 261.31, the following K-waste listing is deleted:

    K160: Solids (including filter wastes, separation solids, and 
spent catalysts) from the production of thiocarbamates and solids 
from the treatment of thiocarbamate wastes.

    In addition, the hazardous waste listings for K156, K157, and K158 
are amended. Originally, they read as follows:

    K156: Organic waste (including heavy ends, still bottoms, light 
ends, spent solvents, filtrates, and decantates) from the production 
of carbamates and carbamoyl oximes.
    K157: Wastewaters (including scrubber waters, condenser waters, 
washwaters, and separation waters) from the production of carbamates 
and carbamoyl oximes.
    K158: Bag house dusts and filter/separation solids from the 
production of carbamates and carbamoyl oximes.

EPA is modifying each of these three listing descriptions to include 
the following limitation: (This listing does not apply to wastes 
generated from the manufacture of 3-iodo-2-propynyl n-butylcarbamate.)
    EPA is not deleting any constituents in the Appendix VIII hazardous 
constituent list of 40 CFR part 261, since the Dithiocarbamate Task 
Force ruling did not affect those listings. The Agency is, however, 
deleting any mention of the associated vacated hazardous waste codes in 
Appendix VIII. While the regulations for waste management at 40 CFR 
parts 262 through 264 are not affected by the court's ruling, it is 
clear

[[Page 32976]]

that they are not applicable to any of the vacated hazardous waste 
listings (unless those wastes exhibit a hazardous waste characteristic 
described under 40 CFR 261.20 to 261.24). However, to the extent that 
the wastes described in the vacated listings were included in federal 
permits before the ruling, appropriate action may need to be taken by 
permittees and permitting authorities to amend the permits. Any need to 
revise state permits will depend on state law. Since state law may be 
more stringent than federal law (see RCRA section 3009) there may be 
circumstances in which carbamate listings would be required to remain 
in the permits.
    The land disposal restriction (LDR) regulations for hazardous 
wastes are amended to remove the U and K wastes vacated by the court. 
Specifically the Agency is amending 40 CFR 268.39 to remove LDRs for 
K160, U277, U365, U366, U375, U376, U377, U378, U379, U381, U382, U383, 
U384, U385, U386, U390, U391, U392, U393, U396, U400, U401, U402, U403, 
and U407.
    In addition, the description of the K156, K157 and K158 wastes in 
40 CFR 268.40 are amended to reflect the fact that they do not apply to 
wastes from production of IPBC.
    In a recent action to correct tables applicable to the LDR 
regulations (62 FR 7501, February 19, 1997), the Agency removed the 
vacated carbamate hazardous waste codes from the list of treatment 
standards contained in section 268.40 and removed Cycloate and IPBC 
from the Universal Treatment Standards (UTS) table in 40 CFR 268.48. 
The hazardous waste listings based on these two constituents were 
vacated by the Dithiocarbamate Task Force ruling and these constituents 
have not been cited as the basis for listing any other hazardous waste 
in Appendix VII of part 261. EPA notes these constituents are still 
listed in Appendix VIII of 40 CFR part 261 as hazardous constituents 
upon which EPA may base listings.
    All other constituents on the Universal Treatment Standards table 
are being retained. This is because they remain the basis for listed 
hazardous wastes that have not been affected by the Dithiocarbamate 
Task Force ruling. Accordingly, the UTS standards for the following 
constituents which are part of the basis for K159 are retained: 
Butylate, EPTC, Molinate, Pebulate, and Vernolate. Also retained is 
Dithiocarbamates (total). The determination of total dithiocarbamates 
is part of the basis for listing of K161, which was not invalidated by 
the court ruling.
    Today's final rule also removes the vacated U and K wastes from 
CERCLA designation as hazardous substances. Accordingly, all these 
wastes are removed from the list of CERCLA hazardous substances at 40 
CFR 302.4.

III. State Authority

    The tables in 40 CFR 271.1 are amended to reflect the issuance of 
this notice so that States will understand they are not required by the 
federal Resource Conservation and Recovery Act to adopt the hazardous 
waste listings vacated by the Dithiocarbamate Task Force ruling. Since 
today's rule does not establish any new regulation, no additional 
requirements or obligations are imposed on the States by its 
promulgation. RCRA section 3009 provides that States may not issue 
regulations less stringent than those authorized under Subtitle C of 
RCRA. However, section 3009 of RCRA also provides that States may 
impose more stringent requirements than those regulations promulgated 
by EPA under Subtitle C. Thus, regulations vacated by the 
Dithiocarbamate Task Force ruling may be permissible under state law.

IV. Good Cause Exemption From Notice-and-Comment Rulemaking 
Procedures

    The Administrative Procedure Act generally requires agencies to 
provide prior notice and opportunity for public comment before issuing 
a final rule. 5 U.S.C. 553(b). Rules are exempt from this requirement 
if the issuing agency finds for good cause that notice and comment are 
unnecessary. 5 U.S.C. 553(b)(3)(B).
    EPA has determined that providing prior notice and opportunity for 
comment on the amending of these carbamate regulations is unnecessary. 
These regulations are no longer legally in effect by order of the 
federal appeals court. Thus, amending them has no legal impact and only 
states the current legal status of the rules.
    For the same reasons, EPA believes there is good cause for making 
the amending of these regulations immediately effective. See 5 U.S.C. 
553(d).

V. Analyses Under E.O. 12866, Unfunded Mandates Reform Act of 1995, 
Regulatory Flexibility Act, Small Business Regulatory Enforcement 
Fairness Act of 1996 and Paperwork Reduction Act

    The amending of the carbamate regulations only reflects their 
current legal status and has no regulatory impact, therefore, this 
action is not a ``significant'' regulatory action by E.O. 12866. 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 annual costs of $100 million or more, will 
not significantly or uniquely affect small governments, and is not a 
significant federal intergovernmental mandate. The Agency thus has no 
obligations under sections 202, 203, 204 and 205 of the Unfunded 
Mandates Reform Act. Moreover, since this action is not subject to 
notice-and-comment requirements under the Administrative Procedure Act 
or any other statute, it is not subject to sections 603 or 604 of the 
Regulatory Flexibility Act.
    Under 5 U.S.C. 801(a)(1)(A), added by the Small Business Regulatory 
Enforcement Fairness Act of 1996, EPA submitted 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 General 
Accounting Office prior to publication of the rule in today's Federal 
Register. This rule is not a ``major rule'' as defined by 5 U.S.C. 
804(2).
    Lastly, the removal of these regulations from the Code of Federal 
Regulations does not affect requirements under the Paperwork Reduction 
Act since they are no longer legally in effect.
