Land Disposal Restrictions: Nevada and California; Site Specific Treatment Variances for Hazardous Selenium Bearing Waste

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Direct final rule.

SUMMARY:

EPA is taking direct final actions to both issue a site-specific treatment variance to U.S. Ecology Nevada (USEN) in Beatty, Nevada and to withdraw an existing site-specific treatment variance issued to Chemical Waste Management, Inc. (CWM) in Kettleman Hills, California. These actions pertain to the treatment of a hazardous waste generated by the Owens-Brockway Glass Container Company in Vernon, California that is unable to meet the concentration-based treatment standard for selenium established under the Land Disposal Restrictions program. The site-specific treatment variance issued to USEN provides an alternative treatment standard of 59 mg/L for selenium as measured by the Toxicity Characteristic Leaching Procedure. EPA has determined that the treatment performed by USEN provides the best demonstrated treatment available for this waste by reducing the potential amount of selenium released to the environment, while minimizing the total volume of hazardous waste land disposed.

DATES:

This direct final rule will be effective June 6, 2011 without further notice, unless EPA receives adverse written comment by May 6, 2011. If EPA receives adverse comments, EPA will publish a timely withdrawal in the Federal Register informing the public that the direct final rule will not take effect.

SUPPLEMENTARY INFORMATION:

A. Why is EPA using a direct final rule?

EPA is publishing this rule as a direct final rule because we view this action as a noncontroversial action and anticipate no adverse comment. Based on the information and data submitted by the petitioner for this site-specific treatment variance and the oversight being provided by the regulatory authorities in the states of Nevada and California, we do not believe that there will be adverse comments on this action. However, in the “Proposed Rules” section of today's Federal Register, we are publishing a separate document that will serve as a proposed rule should EPA receive adverse comments. We will not institute a second comment period on this action. Any parties interested in commenting must do so at this time. For further information about commenting on this rule, see the ADDRESSES section of this document.

If EPA receives adverse comment, we will publish a timely withdrawal in the Federal Register informing the public that this direct final rule will not take effect. We would address all public comments in any subsequent final rule based on the proposed rule.

If we do not receive adverse comment, the rule will take effect on June 6, 2011. Section 3010(b) of RCRA states that rules implementing subtitle C of RCRA normally take effect six months after promulgation, but that EPA may provide for a shorter effective date for rules with which the regulated community does not need six months to come into compliance. This is such a rule, as the Owens-Brockway Glass Container Company should be able to transport the waste to USEN for treatment and disposal in a much shorter period of time.

B. Does this action apply to me?

This action applies only to U.S. Ecology Nevada located in Beatty, Nevada and to Chemical Waste Management, Inc. located in Kettleman Hills, California.

I. Background

A. Basis for Land Disposal Restrictions Treatment Variances

Under sections 3004(d) through (g) of the Resource Conservation and Recovery Act (RCRA), the land disposal of hazardous wastes is prohibited unless such wastes are able to meet the treatment standards established by EPA. Under section 3004(m) of RCRA, EPA is required to set “levels or methods of treatment, if any, which substantially diminish the toxicity of the waste or substantially reduce the likelihood of migration of hazardous constituents from the waste so that short-term and long-term threats to human health and the environment are minimized.” EPA interprets this language to authorize treatment standards based on the performance of the best demonstrated available technology (BDAT). This interpretation was upheld by the DC Circuit in Hazardous Waste Treatment Council v. EPA, 886 F. 2d 355 (D.C. Cir. 1989).

The Agency recognizes however, that there may be wastes that cannot be treated to the levels specified in the regulations (see 40 CFR 268.40) because an individual waste matrix or concentration can be substantially more difficult to treat than those wastes evaluated in establishing the treatment standard (51 FR 40576, November 7, 1986). For such wastes, EPA has a process by which a generator or treater may seek a treatment variance (see 40 CFR 268.44). If granted, the terms of the variance establish an alternative treatment standard for the particular waste at issue.

B. Basis of the Current Selenium Treatment Standard

Treatment of selenium poses special difficulties. In particular, it can be technically challenging to treat wastes containing selenium and other metals e.g., cadmium, lead and/or chromium because of their different chemical properties and solubility curves (62 FR 26041, May 12, 1997).

The current treatment standard for a waste exhibiting the toxicity characteristic for selenium (RCRA Hazardous Waste D010) is based upon the performance of stabilization on low concentration selenium wastes. When the Agency developed the treatment standard for selenium, EPA believed that wastes containing high concentrations of selenium were rarely generated and land disposed (59 FR 47980, September 19, 1994). The Agency also stated that it believed that, for most wastes containing high concentrations of selenium, recovery of the selenium would be feasible using recovery technologies currently employed by copper smelters and copper refining operations (Id.). The Agency further stated in 1994, that it did not have any performance data for selenium recovery, but available information indicated that some recovery of elemental selenium out of certain types of scrap material and other wastes was practiced in the United States.

In 1994, the Agency used performance data from the stabilization of a mineral processing waste that was characteristically hazardous (RCRA Hazardous Waste D010) to set the national treatment standard for selenium. At that time, we determined that this was the most difficult to treat selenium waste. This untreated waste contained up to 700 ppm total selenium and 3.74 mg/L selenium as measured by the Toxicity Characteristic Leaching Procedure (TCLP). The resulting post-treatment levels of selenium in the TCLP leachate were between 0.154 mg/L and 1.80 mg/L, which (after considering the range of treatment process variability) led to EPA establishing a national treatment standard of 5.7 mg/L for D010 selenium nonwastewaters. This D010 mineral processing waste also contained other toxic metals (i.e., arsenic, cadmium, and lead) above the characteristic levels. The treatment technology used to establish the selenium levels also resulted in meeting the Land Disposal Restrictions (LDR) treatment standards for these non-selenium metals. The waste to reagent ratios varied from 1:1.3 to 1:2.7 (62 FR 26041).

Thus, in the Phase IV final rule, the Agency determined that a treatment standard of 5.7 mg/L, as measured by the TCLP, continued to be appropriate for D010 nonwastewaters (63 FR 28556, May 26, 1998). The Agency also changed the universal treatment standard (UTS) for selenium nonwastewaters from 0.16 mg/L to 5.7 mg/L TCLP.

C. Site-Specific Treatment Variance for Selenium-Bearing Waste

On May 26, 1999 (64 FR 28387), EPA granted Chemical Waste Management, Inc. (CWM) in Kettleman Hills, California a site-specific treatment variance from the LDR treatment standards for hazardous selenium-bearing waste generated by the Owens- Brockway Glass Container Company (Owens-Brockway) at their Vernon, California manufacturing facility. Under 40 CFR 268.44(o), CWM was allowed to treat the waste to an alternative treatment standard for selenium of 51 mg/L TCLP with a waste to reagent ratio of 1 to 2.7. Total selenium concentrations in the electrostatic precipitator (ESP) dust generated at the Owens-Brockway facility range from 2,400 mg/kg to 5,700 mg/kg. The untreated waste has a leachable selenium concentration ranging from 228 mg/L to 440 mg/L TCLP. In addition, the untreated waste has a leachable arsenic concentration ranging from 3.3 mg/L to 8.6 mg/L TCLP, a leachable cadmium concentration ranging from 3.9 mg/L to 11.0 mg/L TCLP, and a leachable lead concentration ranging from <0.10 mg/L to 16.3 mg/L TCLP. (For a more detailed discussion of EPA's basis for granting the site-specific treatment variance to CWM, see 64 FR 28387, May 26, 1999.)

II. Basis for This Determination

Under 40 CFR 268.44, facilities can apply for a site-specific treatment variance in cases where a waste that is generated under conditions specific to only one site cannot be treated to the specified LDR treatment standards. In such cases, the generator(s) or the treatment facility may apply to the Administrator, or to EPA's designated representative, (in this case the Assistant Administrator for Solid Waste and Emergency Response) for a site-specific variance from a treatment standard. The applicant for a site-specific variance must demonstrate that, because the physical or chemical properties of the waste differ significantly from the waste analyzed in developing the treatment standard, the waste cannot be treated to the specified levels or by the specified methods. There are other grounds for obtaining variances, but this is the only provision relevant to this action.

III. Development of This Variance

A. U.S. Ecology Nevada Petition

On September 16, 2008, U.S. Ecology Nevada (USEN) submitted a petition requesting a site-specific treatment variance from the LDR treatment standards for hazardous selenium-bearing waste generated by Owens-Brockway at their Vernon, California manufacturing facility. USEN requested an alternative treatment standard of 59 mg/L as measured by the TCLP for the selenium contained in the waste. This alternative treatment standard was achieved with a waste to reagent ratio of 1 to 0.45, using 20% ferrous sulfate, 15% quick lime and 10% sodium sulfide flakes.

B. What type and how much waste will be subject to this variance?

Owens-Brockway operates a glass manufacturing facility that ESP dust. The ESP dust is generated by the glass furnace air emissions control system and is hazardous due to its high concentrations of leachable arsenic, cadmium, lead, and selenium. The corresponding EPA hazardous waste codes are D004, D006, D008, and D010, respectively. The waste generated by Owens-Brockway does not meet the LDR treatment standards and requires treatment prior to land disposal. As discussed previously, the physical properties and the chemical composition of the ESP dust generated by Owens-Brockway are considerably different from the waste used to establish the current LDR treatment standard for selenium. The Agency set the national treatment standard for nonwastewaters using performance data from the stabilization of a characteristically hazardous mineral processing waste, which the Agency determined at the time to be the most difficult to treat selenium waste.

According to the petition submitted by USEN, the quantity of ESP dust shipped off-site for management as a hazardous waste ranges from 50 to 100 tons per year. The ESP dust, as generated, contains fine particle matter resulting from the combustion of natural gas and particulate matter generated by the dry scrubber used to control SO_X emissions. The material is normally returned to the process as a substitute raw material; however, there are circumstances when it cannot be used again due to the high levels of hazardous contaminants, its physical state or excess quantity. In these situations, the ESP dust is managed as a RCRA hazardous waste.

C. Description of the Waste Treatment Process

USEN will stabilize the Owens-Brockway ESP dust using a combination of reagents and techniques. These reagents include ferrous sulfate (FeSO4), quick lime (CaO), and sodium sulfide (Na2S). USEN typically uses a combination of hydroxide and sulfide precipitation to treat high concentration wastes. Most often, an alkaline reagent (quick lime) is used to raise the solution pH to lower the solubility of the metal constituents and start the precipitation process.

As noted previously, (see 64 FR 28387, May 26, 1999), EPA concluded that it is difficult, if not impossible, to optimize the treatment for selenium when other metals are being treated, because the selenium solubility curve differs from that of most other metals. Thus, successfully stabilizing other metals generally means that treatment for selenium cannot be optimized. As further pointed out in the petition submitted by USEN, selenium's minimum solubility is in the range of 6.5 to 7.5, while other characteristic metals have a minimum solubility in the pH range of 8 to 12. In simple terms, if you maximize the stabilization treatment recipe to treat arsenic, cadmium, and lead, the selenium becomes soluble and will not meet the treatment standard (i.e., fail the TCLP). If you maximize the recipe to treat selenium, the other metals will not meet the treatment standard.

USEN has been unsuccessful in developing a treatment recipe that can achieve all the LDR treatment standards applicable to this waste (e.g., arsenic, chromium, lead, and selenium). USEN tested and submitted performance data on 135 treatment recipes on five different ESP dust samples using a combination of reagents and concentrations of reagents. USEN was unable to achieve the LDR treatment standard of 5.7 mg/L selenium using any of the 135 treatment recipes. The average post treatment selenium TCLP value achieved was 47 mg/L TCLP, which is approximately a 90% reduction in soluble selenium. The treatment to an average of 47 mg/L TCLP was the result of a recipe with a waste to reagent ratio of 1:0.45. With a variability factor applied to the average TCLP selenium value, the final treatment standard would be 59 mg/L TCLP.

With the data and information provided to the Agency as part of their site-specific treatment variance petition, EPA was able to perform an analysis which shows that the USEN treatment process would generate a lower volume of waste material, post treatment, coupled with a lower potential for selenium being released to the environment. Mass balance calculations performed by the Agency indicated that the treatment conducted by USEN has the potential to release between 3.88 to 7.76 kilograms (8.54 to 17.1 pounds) of selenium per year to the environment. This range is a result of Owens-Brockway generating between 50 and 100 tons of waste annually. (As we discuss in the next section, CWM, even with a lower alternative treatment standard, has the potential to release greater amounts of selenium per year to the environment. This is due to the higher waste to reagent ratio used to stabilize the waste material. ) As such, the Agency has determined that USEN has optimized its stabilization recipe by reducing the amount of selenium potentially released to the environment and minimizing the amount of reagent that must be used to achieve this result.

IV. EPA's Reasons for Granting This Site-Specific Treatment Variance to USEN and Withdrawing the Site-Specific Variance From CWM at 40 CFR 268.44

EPA has reviewed USEN's petition for a site-specific treatment variance from the LDR treatment standards for hazardous selenium-bearing waste generated by Owens-Brockway and is granting a variance from the selenium treatment standard from 5.7 mg/L TCLP to an alternative treatment standard of 59 mg/L TCLP, with the condition that USEN does not exceed a waste to reagent ratio of 1:0.45. Concurrently, EPA is withdrawing the site-specific variance granted to CWM that established an alternative treatment standard of 51 mg/L TCLP for this same waste (69 FR 6567, February 11, 2004).

EPA has determined that USEN, despite having a higher selenium treatment standard based on selenium concentration, does, in fact, have the potential to release less selenium in a land disposal environment by utilizing a much more environmentally favorable waste to reagent ratio. As such, the Agency believes that the treatment performed by USEN is the best treatment available for this waste. CWM uses a waste to reagent ratio of 1:2.7, while USEN uses a waste to reagent ration of 1:0.45. Consequently, the Agency has determined that a treatment standard of 59 mg/L TCLP for this selenium-bearing waste is more protective of human health and the environment, due to the fact that it generates a lower volume of waste material, with a much lower leaching potential. In particular, the treatment process employed by CWM has the potential to release between 8.56 to 17.11 kilograms (18.8 to 37.69 pounds) of selenium per year to the environment, whereas USEN has the potential to release 3.88 to 7.76 kilograms (8.54 to 17.1 pounds) of selenium per year to the environment. Furthermore, utilizing the waste to reagent ratio of 1:2.7 would dispose of between 185 and 370 tons of waste to land disposal per year, whereas utilizing the waste to reagent ratio of 1:0.45 would dispose of only 72.5 to 145 tons of waste to land disposal per year.

Based on the foregoing, the Agency is granting USEN's petition for a site-specific treatment variance for the ESP dust generated at the Owens-Brockway glass manufacturing plant in Vernon, California. We are also withdrawing the portion of CWM's site-specific treatment variance that pertains to its management of the Owens-Brockway waste, i.e., 51 mg/L TCLP for selenium-bearing D010 waste.

Technology-based treatment standards, whether adopted by generally applicable rule or through a variance to the generally applicable rule, serve as the measure of when threats posed by land disposal of the hazardous waste are “minimized,” as required by RCRA section 3004(m). See 55 FR 6640 (February 26, 1990). Thus, EPA has typically limited the standards adopted by a variance to a single standard. See 70 FR 44505 (August 3, 2005). We are continuing this practice here by rescinding the current variance granted to CWM (69 FR 6567, February 11, 2004). The Agency has determined that the existing treatment standard is less stringent than the standard we would now be granting, both with respect to potential concentrations of selenium released to the environment and also the waste to reagent ratios. Under these circumstances, EPA believes that threats posed by land disposal are minimized by use of the treatment process utilized by USEN.

Please note that the waste already disposed of pursuant to the standard established in the original treatment variance granted to CWM would be lawfully disposed, and would not have to be retreated if the standard in the variance were altered or lapsed. This variance results in amending 40 CFR 268.44(o) to allow hazardous selenium-bearing waste generated by Owens-Brockway in Vernon, California, with the RCRA hazardous waste identification code of D010, to be treated to an alternate treatment standard of 59 mg/L TCLP by USEN with the condition that the waste to reagent ratio not exceed 1:0.45.

V. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review

This action is not a “significant regulatory action” under the terms of Executive Order 12866 (58 FR 51735, October 4, 1993) and is therefore not subject to review under the Executive Order.

B. Paperwork Reduction Act

This action does not impose any new information collection burden. This action does two things: (1) Grants a site-specific treatment variance to USEN for the treatment of hazardous selenium-bearing waste under RCRA's LDR program; and (2) withdraws an existing site-specific treatment variance to CWM. The Office of Management and Budget (OMB) has previously approved the information collection requirements contained in the existing regulations at 40 CFR 268.42 and .44 under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. and has assigned OMB control number 2050-0085. The OMB control numbers for EPA's regulations in 40 CFR are listed in 40 CFR part 9.

C. Regulatory Flexibility Act

The Regulatory Flexibility Act (RFA) generally requires an agency to prepare a regulatory flexibility analysis of any rule subject to notice and comment rulemaking requirements under the Administrative Procedure Act or any other statute unless the agency certifies that the rule will not have a significant economic impact on a substantial number of small entities. Small entities include small businesses, small organizations, and small governmental jurisdictions.

This site-specific treatment variance does not create any new requirements. Rather, it establishes an alternative treatment standard for a specific waste that applies to only one facility, USEN located in Beatty, Nevada and withdraws an existing site-specific treatment variance for the same waste at CWM located in Kettleman Hills, California. Therefore, we hereby certify that this rule will not add any new regulatory requirements to small entities. This rule, therefore, does not require a regulatory flexibility analysis.

D. Unfunded Mandates Reform Act of 1995

This action contains no Federal mandates under the provisions of Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C. 1531-1538 for State, local, or tribal governments or the private sector. This action imposes no enforceable duty on any State, local or tribal governments or the private sector. This action would not impose any new duties on the State's hazardous waste program. EPA has determined, therefore, that this rule would not contain regulatory requirements that might significantly or uniquely affect small governments in that the authority for this action exists with the Federal government. Therefore, this action is not subject to the requirements of sections 202 or 205 of the UMRA.

This rule is also not subject to the requirements of section 203 of UMRA because it contains no regulatory requirements that might significantly or uniquely affect small governments.

E. Executive Order 13132: Federalism

This action does not have federalism implications. This rule 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. This action does two things: (1) Grants a site-specific treatment variance applicable to one facility, and (2) withdraws a site-specific treatment variance for that same waste at another facility. Thus, Executive Order 13132 would not apply to this action.

F. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments

This action would not have tribal implications, as specified in Executive Order 13175 (65 FR 67249, November 9, 2000). This action is a site-specific treatment variance that applies to only one facility, while withdrawing a site-specific treatment variance for that same waste at another facility. Neither facilities are tribal facilities or located on tribal lands. Thus, Executive Order 13175 would not apply to this action.

G. Executive Order 13045: Protection of Children From Environmental Health Risks and Safety Risks

EPA interprets Executive Order 13045 (62 FR 19885, April 23, 1997) 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 Executive Order has the potential to influence the regulation. This action is not subject to Executive Order 13045 because it would not establish an environmental standard intended to mitigate health or safety risks.

H. Executive Order 13211: Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use

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 would not be a significant regulatory action under Executive Order 12866.

I. National Technology Transfer and Advancement Act

Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (“NTTAA”), Public Law 104-113, 12(d) (15 U.S.C. 272 note) directs EPA 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, and business practices) that are developed or adopted by voluntary consensus standards bodies. NTTAA directs EPA to provide Congress, through OMB, explanations when the Agency decides not to use available and applicable voluntary consensus standards.

This action does not involve technical standards. Therefore, EPA did not consider the use of any voluntary consensus standards.

J. Executive Order 12898: Federal Actions To Address Environmental Justice in Minority Populations and Low-Income Populations

Executive Order 12898 (59 FR 7629 (February 16, 1994)) establishes federal executive policy on environmental justice. Its main provision directs federal agencies, to the greatest extent practicable and permitted by law, to make environmental justice part of their mission by identifying and addressing, as appropriate, disproportionately high and adverse human health or environmental effects of their programs, policies, and activities on minority populations and low-income populations in the United States.

EPA has determined that this rule will not have disproportionately high and adverse human health or environmental effects on minority or low-income populations because it increases the level of protection provided to human health and the environment because of a reduced level of selenium being landfilled than currently occurs. The treatment variance applies to a specific hazardous selenium-bearing waste that will be treated in an existing, permitted RCRA facility, ensuring protection to human health and the environment. Therefore, the rule will not result in any disproportionately negative impacts on minority or low-income communities relative to affluent or non-minority communities.

K. 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 the Congress and to the Comptroller General of the United States. EPA will submit a report containing this rule, when finalized 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. A Major rule cannot take effect until June 6, 2011. This action is not a “major rule” as defined by 5 U.S.C. 804(2).
