[EPA-R07-RCRA-2006-0923; FRL-8258-7]

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

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule and request for comment.

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

SUMMARY: The EPA (also, ``the Agency'' or ``we'' in this preamble) is 
proposing to grant a petition to exclude or ``delist'' wastewater 
treatment sludge from conversion coating on aluminum generated by the 
Ford Motor Company (Ford) Kansas City Assembly Plant (KCAP) in 
Claycomo, Missouri from the requirements of hazardous waste regulations 
under the Resource Conservation and Recovery Act (RCRA). This proposed 
exclusion, if finalized, conditionally excludes the petitioned waste 
from the requirements of hazardous waste regulations under RCRA.
    This petition was evaluated in a manner similar to the expedited 
process developed as a special project in conjunction with the Michigan 
Department of Environmental Quality (MDEQ) for delisting similar wastes 
generated by a similar manufacturing process. See 76 FR 10341, March 7, 
2002. Based on an evaluation of waste-specific information provided by 
Ford, we have tentatively concluded that the petitioned waste from KCAP 
is nonhazardous with respect to the original listing criteria and that 
there are no other factors which would cause the waste to be hazardous. 
This exclusion, if finalized, would be valid only when the sludge is 
disposed of in a Subtitle D landfill which is permitted, licensed, or 
registered by a State to manage industrial solid waste.

I. Background

    Throughout this document whenever ``we,'' ``us,'' or ``our'' is 
used, we mean EPA.

A. What is a delisting petition?

    A delisting petition is a request from a generator to exclude waste 
from the list of hazardous wastes under RCRA regulations. In a 
delisting petition, the petitioner must show that waste generated at a 
particular facility does not meet any of the criteria for which EPA 
listed the waste as set forth in 40 CFR 261.11 and the background 
document for the waste. In addition, a petitioner must demonstrate that 
the waste does not exhibit any of the hazardous waste characteristics 
(that is, ignitability, reactivity, corrosivity, and toxicity) and must 
present sufficient information for us to decide whether factors other 
than those for which the waste was listed warrant retaining it as a 
hazardous waste. (See 40 CFR 260.22, 42 United States Code (U.S.C.) 
6921(f) and the background document for a listed waste.)
    A generator remains obligated under RCRA to confirm that its waste 
remains nonhazardous based on the hazardous waste characteristics even 
if EPA has ``delisted'' the waste and to ensure that future generated 
waste meets the conditions set.

B. What regulations allow a waste to be delisted?

    Under 40 CFR 260.20, 260.22, and 42 U.S.C. 6921(f), a facility may 
petition the EPA to remove its waste from the lists of hazardous wastes 
contained in 40 CFR 261.31 and 261.32. Specifically, 40 CFR 260.20 
allows any person to petition the Administrator to modify or revoke any 
provision of parts 260 through 266, 268, and 273 of 40 CFR.

II. Ford's Petition To Delist Waste From the Kansas City Assembly Plant

A. How is the petitioned wasted generated?

    Ford is petitioning to exclude wastewater treatment sludge 
resulting from a conversion coating process on truck bodies which have 
aluminum components. The truck bodies are

[[Page 76257]]

immersed in a zinc phosphate bath which applies a conversion coating on 
the surface of the metal. The rinses and overflows from the conversion 
coating process comingle with wastewaters from cleaning and rinsing 
operations which may include alkaline cleaners, surfactants, organic 
detergents and rinse conditioners. After the zinc phosphating bath, the 
truck bodies are subjected to an electrocoating process and spray 
painting. Overflows and rinse water from the electrocoating process and 
from the paint booths combine with the wastewater from the conversion 
coating before entering the wastewater treatment plant. When treated, 
the wastewater from the conversion coating on aluminum causes all the 
sludge generated from these wastewaters to be a listed waste, F019.
    In the wastewater treatment plant, large particles are screened out 
and the wastewater is sent to various thickeners and clarifier tanks 
where water and solids are further separated. The pH of the wastewater 
may be adjusted and flocculents and coagulants may be added to 
facilitate the thickening process. The solids which settle in the 
thickeners and clarifiers are dewatered in a filter press and the 
resultant F019 filter cake drops into a roll off box for disposal.
    The zinc phosphating process used today does not contain hexavalent 
chromium or cyanide for which F019 was originally listed, but trivalent 
chromium, nickel, and zinc may be present in the wastewater and in the 
sludge. Other hazardous constituents such as organic solvents, 
formaldehyde or additional metals could also be in the waste stream. 
Before a waste can be delisted, the petitioner must demonstrate that 
there are no hazardous constituents in the sludge from other operations 
in the plant at levels of concern and that there are no other factors 
that might cause the waste to be hazardous. Ford believes that its 
sludge does not contain the constituents for which F019 was listed and 
that there are no other constituents or factors that would cause the 
waste to remain hazardous.

B. What is the process for delisting F019 from zinc phospating 
operations at automobile and light truck assembly plants?

    The zinc phosphating process used by Ford at KCAP is substantially 
similar to the process used at most automobile and light truck assembly 
plants in conversion coating steel and aluminum. A number of automobile 
and light truck assembly plants have been granted hazardous waste 
exclusions as a result of a special expedited delisting project 
established in a Memorandum of Understanding (MOU) between EPA Region 5 
and MDEQ (67 FR 10341, March 7, 2002, and 68 FR 44652, July 30, 2003). 
These facilities were able to take advantage of a common sampling 
approach and expedited rulemaking procedure mainly due to the 
similarity of the wastes and processes generating the waste. Ford 
certified that the process generating the filter cake at KCAP is 
consistent with the process described in the MOU for expedited 
delistings.
    Using available historical data and other information, the 
expedited process identified 70 constituents which might be of concern 
in the F019 waste generated at automobile and light truck assembly 
plants, and a Sampling and Analysis Plan was developed specifically for 
testing this waste. EPA agreed to allow Ford to use the same Sampling 
and Analysis Plan and the same list of constituents of concern to 
demonstrate that the levels of constituents in the waste at KCAP are 
below the levels of concern that could pose a threat to human health or 
the environment when the waste is disposed in a nonhazardous landfill.

C. What information did Ford submit in support of its petition?

    To support its exclusion demonstration, Ford collected six samples 
representing waste generated at KCAP over six weeks. All sampling was 
done in accordance with the Sampling and Analysis Plan developed for 
the expedited delisting project but modified to eliminate multiple 
sampling events or long term storage of full roll-off boxes. A 
representative amount of sludge was collected each week for six weeks 
starting with the week of November 1, 2005 and continuing through the 
week of December 12, 2005. The sludge for each week was placed in a 
separate 55 gallon drum, and on December 19, 2005, composite and grab 
samples were collected from all drums. In accordance with the Sampling 
and Analysis Plan, each sample was analyzed for: (1) Total volatile 
organic compound (VOC) analysis using SW-846 8260B with formaldehyde 
analysis using SW-846 8315A, semivolatile organic compound (SVOC) 
analysis using SW-846 8270C; (2) Toxicity Characteristic Leaching 
Procedure (TCLP), Method 1311 in Test Methods for Evaluating Solid 
Waste, Physical/Chemical Methods (SW-846) for the inorganic, VOC and 
SVOC constituents of concern; (3) oil and grease analysis using SW-846 
1664, (4) total metals using SW-846 6010B or 6020 with mercury analysis 
using SW-846 7471A; (5) total constituent analysis for sulfide, SW-846 
Method 9034 and reactive analysis for sulfide, SW-846 Section 7.3; and 
(6) total constituent analysis for cyanide, SW-846 Method 9012A and 
reactive analysis for cyanide, SW-846 Section 7.3. In addition, the pH 
of each sample was measured using SW-846 Method 9045C and a 
determination was made that the waste was not ignitable, corrosive or 
reactive (see 40 CFR 261.21-261.23). The data submitted included the 
appropriate quality assurance/quality control information and was 
validated by an independent third party as required in the Sampling and 
Analysis Plan. The maximum values of constituents detected in any 
sample of the wastewater treatment sludge or in a TCLP extract of that 
sludge are summarized in the table below.

  than those levels expected to be found in the waste. In the event high levels are discovered later, the
  constituent will be evaluated and a delisting level set in accordance with the methodology used to set
  delisting levels for the other constituents.
mg/kg--milligrams per kilogram.
mg/l--milligrams per liter.

    These levels represent the highest constituent concentration found 
in any one sample and do not necessarily represent the specific levels 
found in a single sample.

III. EPA's Evaluation of This Petition

A. How did EPA evaluate the information submitted?

    In developing this proposal, we considered the original listing 
criteria and evaluated additional factors required by the Hazardous and 
Solid Wastes Amendments of 1984 (HSWA). See section 222 of HSWA, 42 
U.S.C. 6921(f), and 40 CFR 260.22(d)(2)-(4). We evaluated the 
petitioned waste against the listing criteria and factors cited in 40 
CFR 261.11(a)(2) and (3). These factors include: (1) Whether the waste 
is considered acutely toxic; (2) the toxicity of the constituents; (3) 
the concentration of the constituents in the waste; (4) the tendency of 
the hazardous constituents to migrate and to bioaccumulate; (5) 
persistence of these constituents in the environment once released from 
the waste; (6) plausible and specific types of management of the 
petitioned waste; (7) the quantity of waste produced; and (8) waste 
variability.
    EPA identified plausible exposure routes (ground water, surface 
water, air) for hazardous constituents released from the waste in an 
improperly managed Subtitle D landfill. To evaluate the waste, we used 
the Delisting Risk Assessment Software program (DRAS), a Windows based 
software tool, to estimate the potential release of hazardous 
constituents from the waste and to predict the risk associated with 
those releases. For a detailed description of the DRAS program and 
revisions see: 65 FR 58015, September 27, 2000; 65 FR 75637, December 
4, 2000; 65 FR 75897, December 5, 2000; and 67 FR 10341, March 7, 2002.

B. What did EPA conclude about this waste?

    EPA compared the analytical results submitted by KCAP to the 
maximum allowable levels calculated by the DRAS for an annual volume of 
2,000 cubic yards. The maximum allowable levels for constituents 
detected in the waste or the waste leachate are summarized in the table 
above. All constituents compared favorably to the allowable levels.
    The table also includes the maximum allowable levels in groundwater 
at a potential receptor well, as evaluated by DRAS. These levels are 
the more conservative of either the Safe Drinking Water Act Maximum 
Contaminant Level (MCL) or the health-based value calculated by DRAS 
based on the target cancer risk level of 1x10 -\6\ or the 
target hazard quotient of one.
    EPA also used the DRAS program to estimate the aggregate cancer 
risk and hazard index for constituents detected in the waste. The 
aggregate cancer risk is the cumulative total of all individual 
constituent cancer risks. The hazard index is a similar cumulative 
total of non-cancer effects. The target aggregate cancer risk is 1x10 
-\5\ and the target hazard index is one. The wastewater 
treatment sludge at KCAP met both of these criteria.

IV. Proposal To Delist Waste From Kansas City Assembly

A. What is EPA proposing?

    Today the EPA is proposing to conditionally exclude or delist 2,000 
cubic yards annually of wastewater treatment sludge generated at KCAP 
from conversion coating on aluminum.

B. What are the terms of this exclusion?

    Ford must dispose of the KCAP waste in a lined Subtitle D landfill 
which is permitted, licensed, or registered by a state to manage 
industrial waste. Ford must verify on a quarterly basis that the 
concentrations of the constituents of concern in the KCAP sludge do not 
exceed the allowable levels set forth in this exclusion. The list of 
constituents for verification is based on the concentration and 
frequency of occurrence of constituents of concern in Ford's KCAP 
sludge and in wastes generated by the majority of facilities 
participating in the expedited process to delist F019. This exclusion 
applies only to a maximum annual volume of 2,000 cubic yards and is 
effective only if all conditions contained in this rule are satisfied.

C. What are the maximum allowable concentrations of hazardous 
constituents in the waste?

    Concentrations of the following constituents measured in the TCLP 
(or OWEP, where appropriate) extract of the waste must not exceed the 
following levels (mg/L): barium--100; chromium--5; mercury--0.155; 
nickel--90; thallium--0.282; zinc--898; cyanides--11.5; ethyl benzene--
42.6; toluene--60.8; total xylenes--18.9; bis(2-ethylhexyl) phthalate--
0.365; p-cresol--11.4; 2,4-dinitrotoluene--0.13; formaldehyde--343; and 
napthalene--0.728. The total concentrations in the waste of the 
following constituents must not exceed the following levels (mg/kg): 
chromium 760000; mercury--10.4; thallium--116000; 2,4-dinitrotoluene--
100000; and formaldehyde--6880.

V. Statutory and Executive Order Reviews

    Under Executive Order 12866, ``Regulatory Planning and Review'' (58

[[Page 76259]]

FR 51735, October 4, 1993), the Agency must determine whether the 
regulatory action is ``significant'' and therefore subject to OMB 
review and the requirements of the Executive Order. It has been 
determined that this rule is not a ``significant regulatory action'' 
under the terms of Executive Order 12866 and therefore is not a 
regulatory action subject to review by the Office of Management and 
Budget (OMB).
    This rule does not impose an information collection burden under 
the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 
et seq.) because it applies to a particular facility only.
    Because this rule is of particular applicability relating to a 
particular facility and does not have a significant economic impact on 
a substantial number of small entities, it is not subject to the 
regulatory flexibility provisions of the Regulatory Flexibility Act (5 
U.S.C. 601 et seq.).
    This rule is not subject to sections 202, 203, 204, and 205 of the 
Unfunded Mandates Reform Act of 1995 (UMRA) (Pub. L. 104-4) because 
this rule will affect only a particular facility. Therefore, EPA has 
determined that this rule does not contain a Federal mandate that may 
result in expenditures of $100 million or more for State, local, and 
tribal governments, in the aggregate, or the private sector in any one 
year.
    Because this rule will affect only a particular facility, this 
final rule does not have federalism implications. It will not have 
substantial direct effects on the States, on the relationship between 
the national government and the States, or on the distribution of power 
and responsibilities among the various levels of government, as 
specified in Executive Order 13132, ``Federalism,'' (64 FR 43255, 
August 10, 1999). Thus, Executive Order 13132 does not apply to this 
rule. Similarly, because this rule will affect only a particular 
facility, this final rule does not have tribal implications, as 
specified in Executive Order 13175, ``Consultation and Coordination 
with Indian Tribal Governments'' (65 FR 67249, November 9, 2000). Thus, 
Executive Order 13175 does not apply to this rule.
    This rule also is not subject to Executive Order 13045,``Protection 
of Children from Environmental Health Risks and Safety Risks'' (62 FR 
19885, April 23, 1997), because it is not economically significant as 
defined in Executive Order 12866, and because the Agency does not have 
reason to believe the environmental health or safety risks addressed by 
this action present a disproportionate risk to children. The basis for 
this belief is that the Agency used the DRAS program, which considers 
health and safety risks to infants and children, to calculate the 
maximum allowable concentrations for this rule.
    This rule is not subject to Executive Order 13211, ``Actions 
Concerning Regulations That Significantly Affect Energy Supply, 
Distribution, or Use'' (66 FR 28355 (May 22, 2001)), because it is not 
a significant regulatory action under Executive Order 12866.
    This rule does not involve technical standards; thus, the 
requirements of section 12(d) of the National Technology Transfer and 
Advancement Act of 1995 (15 U.S.C. 272 note) do not apply.
    As required by section 3 of Executive Order 12988, ``Civil Justice 
Reform,'' (61 FR 4729, February 7, 1996), in issuing this rule, EPA has 
taken the necessary steps to eliminate drafting errors and ambiguity, 
minimize potential litigation, and provide a clear legal standard for 
affected conduct.

List of Subjects in 40 CFR Part 261
