40 CFR Part 261

[SW-FRL-6541-1]


Hazardous Waste Management System; Identification and Listing of 
Hazardous Waste; Final Exclusion

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The EPA is granting a petition submitted by Chaparral Steel 
Midlothian, L.P.(Chaparral Steel) to exclude from hazardous waste 
control (or delist) a certain solid waste. This action responds to the 
petition submitted by Chaparral Steel Midlothian, L.P., to delist the 
leachate from its Landfill No. 3 containing K061 electric arc furnace 
dust and minor amounts of K061 wastewater from various plant operations 
including storm water from the baghouse floor areas and the pelletizer 
sump on a ``generator specific'' basis from the lists of hazardous 
waste.
    After careful analysis, we have concluded that the petitioned waste 
is

[[Page 8875]]

not hazardous waste when disposed of in the surface impoundments. This 
exclusion applies to leachate from Landfill No. 3 containing K061 
electric arc furnace dust and minor amounts of K061 wastewater at 
Chaparral Steel's Midlothian, Texas, facility. Accordingly, this final 
rule excludes the petitioned waste from the requirements of hazardous 
waste regulations under the Resource Conservation and Recovery Act 
(RCRA) when disposed of in surface impoundments but imposes testing 
conditions to ensure that the future-generated wastes remain qualified 
for delisting.

EFFECTIVE DATE: February 23, 2000.

I. Overview Information

A. What Action is EPA Finalizing?

    The EPA is finalizing the decision to grant Chaparral Steel's 
petition to have their leachate and minor amounts of waste water 
excluded, or delisted, from the definition of a hazardous waste.
    After evaluating the petition, EPA proposed, on August 24, 1999, to 
exclude the Chaparral Steel waste from the lists of hazardous wastes 
under Secs. 261.31 and 261.32 (see 64 FR 46166).

B. Why is EPA Approving This Delisting?

    Chaparral Steel petitioned to exclude the landfill leachate and 
other wastewaters because it does not believe that the petitioned waste 
meets the criteria for which it was listed.
    Chaparral Steel also believes that the waste does not contain any 
other constituents that would render it hazardous. Review of this 
petition included consideration of the original listing criteria, as 
well as the additional listing criteria and the additional factors 
required by the Hazardous and Solid Waste Amendments (HSWA) of 1984. 
See, section 222 of HSWA, 42 U.S.C. 6921(f), and 40 CFR 260.22(d)(2)-
(4).
    For reasons stated in both the proposal and this notice, EPA 
believes that Chaparral Steel's landfill leachate and other K061 
wastewaters should be excluded from hazardous waste control. The EPA 
therefore is granting a final exclusion to Chaparral Steel, located in 
Midlothian, Texas, for its leachate from its Landfill No. 3 containing 
K061 electric arc furnace dust and minor amounts of K061 wastewater 
from various plant operations including storm water from the baghouse 
floor areas and the pelletizer sump.

C. What are the Limits of This Exclusion?

    This exclusion applies to the waste described in the petition only 
if the requirements described in Table 1 are met. The waste described 
in the petition is leachate from Landfill No. 3 containing K061 
electric arc furnace dust and minor amounts of K061 wastewater from 
various plant operations including storm water from the baghouse floor 
areas and the pelletizer sump.

D. How Will Chaparral Steel Manage the Waste if it is Delisted?

    The leachate is currently sent to an offsite underground injection 
well facility for disposal. Although management of the wastes covered 
by this petition would not be subject to subtitle C jurisdiction upon 
final promulgation of an exclusion, Chaparral Steel must ensure that 
the onsite management of the delisted wastes is in accordance with the 
Texas Natural Resource Conservation Commission (TNRCC) rules and 
regulations or the waste is delivered to an off-site storage, 
treatment, or disposal facility, either which is permitted, licensed, 
or registered by a State to manage municipal or industrial solid waste.
    The facility would like to manage the waste in their onsite cooling 
system of which cooling ponds are a part. The wastewater would be 
substituted for some of the well water used for cooling purposes which 
would help conserve that natural resource. In this case, the requested 
change in waste management is subject to delisting by EPA and 
subsequent waste management practices in accordance with TNRCC rules 
and regulations.

E. When is the Final Delisting Exclusion Effective?

    This rule is effective February 23, 2000. The Hazardous and Solid 
Waste Amendments of 1984 amended Section 3010(b) of RCRA to allow rules 
to become effective in less than six months when the regulated 
community does not need the six-month period to come into compliance. 
That is the case here because this rule reduces, rather than increases, 
the existing requirements for persons generating hazardous wastes. 
These reasons also provide a basis for making this rule effective 
immediately, upon publication, under the Administrative Procedure Act, 
pursuant to 5 U.S.C. 553(d).

F. How Does This Action Affect States?

    Because EPA is issuing today's exclusion under the Federal RCRA 
delisting program, only States subject to Federal RCRA delisting 
provisions would be affected. This would exclude two categories of 
States: States having a dual system that includes Federal RCRA

[[Page 8876]]

requirements and their own requirements, and States who have received 
our authorization to make their own delisting decisions.
    Here are the details: We allow states to impose their own non-RCRA 
regulatory requirements that are more stringent than EPA's, under 
section 3009 of RCRA. These more stringent requirements may include a 
provision that prohibits a Federally issued exclusion from taking 
effect in the State. Because a dual system (that is, both Federal 
(RCRA) and State (non-RCRA) programs) may regulate a petitioner's 
waste, we urge petitioners to contact the State regulatory authority to 
establish the status of their wastes under the State law.
    The EPA has also authorized some States (for example, Louisiana, 
Georgia, Illinois) to administer a delisting program in place of the 
Federal program, that is, to make State delisting decisions. Therefore, 
this exclusion does not apply in those authorized States. If Chaparral 
Steel transports the petitioned waste to or manages the waste in any 
State with delisting authorization, Chaparral Steel must obtain 
delisting authorization from that State before they can manage the 
waste as nonhazardous in the State.

II. Background

A. What is a Delisting Petition?

    A delisting petition is a request from a generator to EPA or 
another agency with jurisdiction to exclude from the list of hazardous 
wastes, wastes the generator does not consider hazardous under RCRA.

B. What Regulations Allow Facilities to Delist a Waste?

    Under 40 CFR 260.20 and 260.22, facilities may petition the EPA to 
remove their wastes from hazardous waste control by excluding them from 
the lists of hazardous wastes contained in Secs. 261.31 and 261.32. 
Specifically, Sec. 260.20 allows any person to petition the 
Administrator to modify or revoke any provision of parts 260, through 
266, 268, and 273 of Title 40 of the Code of Federal Regulations. 
Section 260.22 provides generators the opportunity to petition the 
Administrator to exclude a waste on a ``generator-specific'' basis from 
the hazardous waste lists.

C. What Information Must the Generator Supply?

    Petitioners must provide sufficient information to EPA to allow the 
EPA to determine that the waste to be excluded does not meet any of the 
criteria under which the waste was listed as a hazardous waste. In 
addition, the Administrator must determine, where he/she has a 
reasonable basis to believe that factors (including additional 
constituents) other than those for which the waste was listed could 
cause the waste to be a hazardous waste, that such factors do not 
warrant retaining the waste as a hazardous waste.

III. EPA's Evaluation of the Waste Data

A. What Waste did Chaparral Steel Petition EPA to Delist?

    Chaparral Steel Midlothian, L.P., petitioned the EPA to exclude 
from hazardous waste control leachate from its Landfill No. 3 
containing K061 electric arc furnace dust and minor amounts of K061 
wastewater from various plant operations including storm water from the 
baghouse floor areas and the pelletizer sump. The listed constituents 
of concern for K061 are chromium, lead, and cadmium.

B. How Much Waste did Chaparral Steel Propose to Delist?

    Specifically, in its petition, Chaparral Steel requested that EPA 
grant an exclusion for leachate from its Landfill No. 3 containing K061 
electric arc furnace dust and minor amounts of K061 wastewater from 
various plant operations including storm water from the baghouse floor 
areas and the pelletizer sump in the amount of 2,500 cubic yards 
(500,000 gallons) generated per calender year.

C. How did Chaparral Steel Sample and Analyze the Waste Data in This 
Petition?

    To support its petition, Chaparral submitted:
    (1) Historical analytical data for the Electric Arc Furnace Dust 
(K061), and leachate analytical data from their Landfill No. 3 
containing the Electric Arc Furnace Dust, and analytical data for the 
liquid from the K061 waste water storage tank;
    (2) Analytical results of the total constituent list for 40 CFR 
part 264, appendix IX volatiles, semivolatiles, metals (including 
hexavalent chromium), pesticides, herbicides, polychlorinated 
biphenyls, furans, and dioxins;
    (3) Analytical results of the constituent list derived from 
appendix IX for identified constituents;
    (4) Analytical results for reactive sulfide;
    (5) Analytical results for reactive cyanide;
    (6) Test results for corrosivity by pH;
    (7) Analytical results of samples from bench tests of treated 
leachate/K061 wastewater; and
    (8) Test results for oil and grease.

IV. Public Comments Received on the Proposed Exclusion

A. Who Submitted Comments on the Proposed Rule?

    i. One commenter supported the delisting but was concerned that the 
rule implies that storm water from melt shop baghouse areas at similar 
facilities would be required to be considered K061 waste water. The EPA 
does not intend to imply that this would be the case. Chaparral Steel 
removes its storm water from the baghouse area and places it in a tank 
containing K061 leachate and manages the waste as K061. Other 
generators must characterize their own storm water based on relevent 
circumstances involved with the generation, management, and disposal of 
the water.
    ii. Two commenters from the same address submitted concerns that 
their private ground water well and the creek on their property would 
become contaminated because of the approval of the delisting. A public 
hearing was requested by these two requestors but not granted.

B. Is the Delisting of Chaparral Steel's Waste a Threat to Ground 
Water?

    No, as explained in the proposed exclusion (delisting), EPA 
concluded that the constituents in the raw leachate, with the exception 
of lead, if released directly to the groundwater would not reach levels 
of concern at a down gradient well. The EPA added as a condition or 
requirement of delisting the waste that the maximum concentration level 
of lead in the leachate could not exceed 0.69 mg/l. See 64 FR 46176. 
The 0.69 mg/l concentration value is the Land Disposal Restriction 
(LDR) value for lead. This concentration is below the health-based 
value of 1.02 mg/l which is a value calculated for a theoretical down 
gradient well. The more conservative value was selected as a delisting 
limit.
    Other assumptions made by EPA in the evaluation process were also 
very conservative. The value for largest amount of leachate generated 
on a per year basis was used in evaluation. Typically, the amount of 
leachate generated on a yearly basis is much less than the maximum and 
the amount generated is decreasing over time. Also, EPA evaluated the 
waste at the highest concentrations found in analyzing the waste or 
worst case concentrations. Actually, concentrations of constituents in 
the waste are less if the average value is used for evaluation 
purposes. If the leachate is added to the cooling system

[[Page 8877]]

as proposed by the facility, the concentrations of the constituents in 
the leachate would be reduced by the well water in the approximately 
eight million gallon cooling system. According to facility information, 
nearly 240 million gallons of well water is added to the system 
annually. The EPA conservatively evaluated a release of raw leachate to 
the ground water and not the leachate diluted by the cooling system 
water. The EPA also conservatively assumed a significant release of raw 
leachate would occur. However, the proposed management scenario for the 
raw leachate is in an above ground tank with secondary containment. 
Therefore, it is very unlikely a significant release to the environment 
would occur.
    Because of the conservative assumptions made above (or reasonable 
worst case scenario), EPA concludes that granting the delisting adds no 
significant threat to contamination of ground water wells in general 
even if not managed as proposed in the onsite cooling pond system. As 
previously stated, although management of the wastes covered by this 
petition would not be subject to subtitle C jurisdiction upon final 
promulgation of an exclusion, Chaparral Steel must ensure that the 
onsite management of the delisted wastes is in accordance with the 
TNRCC rules and regulations or the waste is delivered to an off-site 
storage, treatment, or disposal facility, either which is permitted, 
licensed, or registered by a State to manage municipal or industrial 
solid waste.
    The EPA concludes that granting the delisting adds no significant 
threat to the contamination of the ground water of the commenter's well 
specifically. The commenter's well is about one mile away from the 
cooling water ponds and 500 foot in depth. The soils and geologic 
formations in the area have a low hydraulic conductivity. The 
combination of the distance to the well, the depth to the well, and the 
low hydraulic conductivity make it very unlikely that the commenter's 
well can be contaminated from the delisted waste.

C. Is the Delisting of Chaparral Steel's Waste a Threat to Surface 
Water?

    No, the impact of the petitioned wastes via the surface water route 
is not a threat. If the leachate is added to the cooling system and 
associated holding ponds as proposed by the facility, an overflow is an 
unlikely event and would not ever occur under reasonable circumstances. 
A release to surface water would most potentially occur only if the 
plant was shut down and there was a large rainfall event at the same 
time. In the unlikely event of a release, the facility is required to 
meet applicable storm water permit concentration levels to protect 
human health and the environment.
    Even though release to surface water is unlikely, EPA evaluated a 
100-year, 24 hour rainfall event with the cooling ponds at no freeboard 
capacity which are also unlikely events. Under normal conditions the 
ponds would have enough additional capacity (freeboard) to catch all 
precipitation without an overflow occurring. If such a worst case 
scenario were to occur, calculations indicate that the concentrations 
of the constituents of concern would be below drinking water criteria 
and surface water criteria before reaching the stream at the facility's 
outfall. See regulatory docket for ``Docket Report on Evaluation of 
Contaminant Releases to Surface Water Resulting Form Chaparral Steel 
Midlotian, L.P.'s, Petitioned Waste'' document. Because of these 
reasons, EPA concludes that approving the delisting will not 
significantly impact the stream at the facility's outfall nor at the 
commenter's location which is approximately one mile downstream. The 
delisting is protective of human health and the environment.

D. Are There Any Typographical and Data Transfer Errors From the 
Proposed Delisting Publication?

    The EPA is correcting the maximum organic total constituent 
concentration values for 2-butanone and carbon disulfide found in Table 
1. of the proposed exclusion (64 FR 46169, August 24, 1999). The value 
for 2-butanone total constituent analysis for raw leachate (mg/l) 
should be 0.005 and not 0.003. The value for carbon disulfide total 
constituent analysis for treated leachate (mg/l) should be 0.005 and 
not 0.005.
    The EPA is also making a change in Paragraph (5) of the Table 2 
language to be consistent with Paragraph (6). The sentence which states 
``Failure to submit the required data within the specified time period 
or maintain the required records on site for the specified time will be 
considered by EPA, at its discretion, sufficient basis to revoke the 
exclusion to the extent directed by EPA'' has been altered to read 
``Failure to submit the required data within the specified time period 
or maintain the required records on site for the specified time will be 
considered by EPA, at its discretion, sufficient basis to reopen the 
exclusion as described in Paragraph (6).''

V. Regulatory Impact

    Under Executive Order 12866, EPA must conduct an ``assessment of 
the potential costs and benefits'' for all ``significant'' regulatory 
actions. The final to grant an exclusion is not significant, since its 
effect, if promulgated, would be to reduce the overall costs and 
economic impact of EPA's hazardous waste management regulations. This 
reduction would be achieved by excluding waste generated at a specific 
facility from EPA's lists of hazardous wastes, thereby enabling this 
facility to manage its waste as nonhazardous. There is no additional 
impact due to today's final rule. Therefore, this proposal would not be 
a significant regulation and no cost/benefit assessment is required. 
The Office of Management and Budget (OMB) has also exempted this rule 
from the requirement for OMB review under Section (6) of Executive 
Order 12866.

VI. Regulatory Flexibility Act

    Pursuant to the Regulatory Flexibility Act, 5 U.S.C. 601-612, 
whenever an agency is required to publish a general notice of 
rulemaking for any proposed or final rule, it must prepare and make 
available for public comment a regulatory flexibility analysis which 
describes the impact of the rule on small entities (i.e., small 
businesses, small organizations, and small governmental jurisdictions). 
No regulatory flexibility analysis is required however if the 
Administrator or delegated representative certifies that the rule will 
not have any impact on a small entities.
    This rule if promulgated, will not have an adverse economic impact 
on small entities since its effect would be to reduce the overall costs 
of EPA's hazardous waste regulations. Accordingly, I hereby certify 
that this regulation, if promulgated, will not have a significant 
economic impact on a substantial number of small entities. This 
regulation therefore, does not require a regulatory flexibility 
analysis.

VII. Paperwork Reduction Act

    Information collection and record-keeping requirements associated 
with this final rule have been approved by the OMB under the provisions 
of the Paperwork Reduction Act of 1980 (Public Law 96-511, 44 U.S.C. 
3501 et seq.) and have been assigned OMB Control Number 2050-0053.

VIII. Unfunded Mandates Reform Act

    Under section 202 of the Unfunded Mandates Reform Act of 1995 
(UMRA), Public Law 104-4, which was signed into law on March 22, 1995, 
EPA must prepare a written statement for rules

[[Page 8878]]

with Federal mandates that may result in estimated costs to State, 
local, and tribal governments in the aggregate, or to the private 
sector of $100 million or more in any one year. When such a statement 
is required for EPA rules, under section 205 of the UMRA, EPA must 
identify and consider alternatives, including the least costly, most 
cost-effective or least burdensome alternative that achieves the 
objectives of the rule. The EPA must select that alternative, unless 
the Administrator explains in the final rule why it was not selected or 
it is inconsistent with law. Before EPA establishes regulatory 
requirements that may significantly or uniquely affect small 
governments, including tribal governments, it must develop under 
section 203 of the UMRA a small government agency plan. The plan must 
provide for notifying potentially affected small governments, giving 
them meaningful and timely input in the development of EPA regulatory 
proposals with significant Federal intergovernmental mandates, and 
informing, educating, and advising them on compliance with the 
regulatory requirements. The UMRA generally defines a Federal mandate 
for regulatory purposes as one that imposes an enforceable duty upon 
State, local, or tribal governments or the private sector. The EPA 
finds that today's delisting decision is deregulatory in nature and 
does not impose any enforceable duty upon State, local, or tribal 
governments or the private sector. In addition, the delisting does not 
establish any regulatory requirements for small governments and so does 
not require a small government agency plan under UMRA section 203.

IX. Congressional Review Act

    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 Congress and to the Comptroller General of the United 
States. The EPA will submit a report containing this rule and other 
required information to the U.S. Senate, the U.S. House of 
Representatives, the Comptroller General of the United States prior to 
publication of the final rule in the Federal Register. This rule is not 
a ``major rule'' as defined by 5 U.S.C. 804(2). This rule will become 
effective on the date of publication in the Federal Register.

X. Executive Order 12875

    Under Executive Order 12875, EPA may not issue a regulation that is 
not required by statute and that creates a mandate upon a state, local, 
or tribal government, unless the Federal government provides the funds 
necessary to pay the direct compliance costs incurred by those 
governments. If the mandate is unfunded, EPA must provide to the OMB a 
description of the extent of EPA's prior consultation with 
representatives of affected state, local, and tribal governments, the 
nature of their concerns, copies of written communications from the 
governments, and a statement supporting the need to issue the 
regulation. In addition, Executive Order 12875 requires EPA to develop 
an effective process permitting elected officials and other 
representatives of state, local, and tribal governments ``to provide 
meaningful and timely input in the development of regulatory proposals 
containing significant unfunded mandates.'' Today's rule does not 
create a mandate on state, local or tribal governments. The rule does 
not impose any enforceable duties on these entities. Accordingly, the 
requirements of section 1(a) of Executive Order 12875 do not apply to 
this rule.

XI. Executive Order 13045

    The Executive Order 13045 is entitled ``Protection of Children from 
Environmental Health Risks and Safety Risks'' (62 FR 19885, April 23, 
1997). This order applies to any rule that EPA determines: (1) Is 
economically significant as defined under Executive Order 12866, and 
(2) the environmental health or safety risk addressed by the rule has a 
disproportionate effect on children. If the regulatory action meets 
both criteria, the Agency must evaluate the environmental health or 
safety effects of the planned rule on children, and explain why the 
planned regulation is preferable to other potentially effective and 
reasonably feasible alternatives considered by the Agency. This rule is 
not subject to Executive Order 13045 because this is not an 
economically significant regulatory action as defined by Executive 
Order 12866.

XII. Executive Order 13084

    Under Executive Order 13084, EPA may not issue a regulation that is 
not required by statute, that significantly affects or uniquely affects 
the communities of Indian tribal governments, and that imposes 
substantial direct compliance costs on those communities, unless the 
Federal government provides the funds necessary to pay the direct 
compliance costs incurred by the tribal governments. If the mandate is 
unfunded, EPA must provide to the Office of Management and Budget, in a 
separately identified section of the preamble to the rule, a 
description of the extent of EPA's prior consultation with 
representatives of affected tribal governments, a summary of the nature 
of their concerns, and a statement supporting the need to issue the 
regulation. In addition, Executive Order 13084 requires EPA to develop 
an effective process permitting elected and other representatives of 
Indian tribal governments ``to meaningful and timely input'' in the 
development of regulatory policies on matters that significantly or 
uniquely affect their communities of Indian tribal governments. Today's 
rule does not significantly or uniquely affect the communities of 
Indian tribal governments. Accordingly, the requirements of section 
3(b) of Executive Order 13084 do not apply to this rule.

XIII. National Technology Transfer and Advancement Act

    Under Section 12(d) of the National Technology Transfer and 
Advancement Act, the Agency is directed to use voluntary consensus 
standards in its regulatory activities unless to do so would be 
inconsistent with applicable law or otherwise impractical. Voluntary 
consensus standards are technical standards (e.g., materials 
specifications, test methods, sampling procedures, business practices, 
etc.) developed or adopted by voluntary consensus standard bodies. 
Where available and potentially applicable voluntary consensus 
standards are not used by EPA, the Act requires that Agency to provide 
Congress, through the OMB, an explanation of the reasons for not using 
such standards.
    This rule does not establish any new technical standards and thus, 
the Agency has no need to consider the use of voluntary consensus 
standards in developing this final rule.
