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

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 areimmersed 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.

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 1×10 [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 1×10 [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” (58FR 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.

Ford must compile, summarize, and maintain at KCAP records of operating conditions and analytical data for a minimum of five years. Ford must make these records available for inspection. All data must be accompanied by a signed copy of the certification statement in 40 CFR 260.22(i)(12).
5. Reopener Language—(a) If, anytime after disposal of the delisted waste, Ford possesses or is otherwise made aware of any data (including but not limited to leachate data or groundwater monitoring data) relevant to the delisted waste at KCAP indicating that any constituent is at a level in the leachate higher than the specified delisting level, or is in the groundwater at a concentration higher than the maximum allowable groundwater concentration in paragraph (e), then Ford must report such data in writing to the Regional Administrator within 10 days of first possessing or being made aware of that data.
(b) Based on the information described in paragraph (a) and any other information received from any source, the Regional Administrator will make a preliminary determination as to whether the reported information requires Agency action to protect human health or the environment. Further action may include suspending, or revoking the exclusion, or other appropriate response necessary to protect human health and the environment.
(c) If the Regional Administrator determines that the reported information does require Agency action, the Regional Administrator will notify Ford in writing of the actions the Regional Administrator believes are necessary to protect human health and the environment. The notice shall include a statement of the proposed action and a statement providing Ford with an opportunity to present information as to why the proposed Agency action is not necessary or to suggest an alternative action. Ford shall have 30 days from the date of the Regional Administrator's notice to present the information.
(d) If after 30 days Ford presents no further information, the Regional Administrator will issue a final written determination describing the Agency actions that are necessary to protect human health or the environment. Any required action described in the Regional Administrator's determination shall become effective immediately, unless the Regional Administrator provides otherwise.
