Modification of Definition of Solid WasteThis proposes to modify the definition of solid waste regarding hazardous secondary materials. Under this
proposal, provided the secondary materials are not inherently waste-like, used in a manner constituting disposal, or burned for energy recovery, they are not solid waste when generated and reclaimed in a
"continuous process" within the "same industry".
Another approach discussed in the preamble, but not proposed, would allow materials generated and reclaimed in a continuous process at the
same site to be excluded from the definition of solid waste regardless of whether different industries were involved. EPA is also accepting comments on this approach.
Determining "Same Industry"
The North American Industry Classification System (NAICS) is proposed as the basis for determining whether secondary materials remain within the same industry. For
the most part, industries with the same first four digits of this six digit classification system would be considered to be within the same industry. These industry codes are listed in proposed Appendix X to Part
261. Exceptions are discussed in the preamble regarding the primary mineral processing industry, the petroleum industry, NAICS classification 3256 (soap, cleaning compound, and toilet preparation manufacturing),
NAICS classification 3259 (other chemical product and preparation manufacturing), and waste management and remediation services.
Determining "Continuous Process Within the Same Industry"
To be considered "generated and reclaimed in a continuous process within the same industry", material can not be handled by any entity
or facility outside of the generating industry (except for a transporter) and the materials can not be speculatively accumulated. This means that handlers other than transporters must be have the same 4 digit
NAICS industry classification.
Two approaches for determining eligibility of reclamation facilities are proposed. Under Option 1:
- Both generation and reclamation would need to occur within the same industry (same 4 digit NAICS)
- Reclamation would be allowed to involved one or more processing steps, provided that all steps take place within the same industry in which the secondary material was generated
- The reclamation would be required to produce a product or ingredient that is used or reused without further reclamation.
- The reclamation steps would not be required to take place at the site where the material was generated, provided such reclamation activities take place within the generating industry.
Option 2 is identical to option 1, but would make a reclamation facility ineligible for the solid waste exclusion if it also recycles hazardous waste from a different industry. EPA requests comments
on both approaches.
Notifications
Proposed 40 CFR 261.2(g)(4) would require generators of secondary materials that have previously been subject to regulation as hazardous wastes, but
which are newly excluded via 40 CFR 261.2(g), to submit a one-time notice to the Regional Administrator. The notification would include the name, address, and EPA ID number (if applicable) of the generating facility;
the name and telephone number of the contact person; the type of material subject to exclusion; and the industry that generated the material as classified according to NAICS in Appendix X of part 261. In addition,
preamble discussion solicits comments on requiring persons using the 40 CFR 261.2(g) exclusion to submit periodic reports detailing recycling activities and to maintain records documenting the conditions of the
exclusion have been met.
Legitimate Recycling vs Sham Recycling
Historically, EPA has provided regulatory relief for legitimate recycling, but not for "sham recycling" where
wastes are treated or disposed under the guise of recycle. This has been the subject of EPA memorandums, but was not formally codified. EPA now proposes to establish formal regulations within 40 CFR 261.2(h)
to address legitimate recycling. This proposes "Hazardous waste must be legitimately recycled to qualify for special management standards under 40 CFR 261.6 and 40 CFR 266." This includes recyclables such as
scrap metal, precious metals, lead-acid batteries, etc.
The four proposed criteria to be considered when determining legitimacy of recycling and are as follows:
- Criterion 1: The secondary material to be recycled is managed as a valuable commodity. Where there is an analogous raw material, the secondary material should be managed in a manner consistent with the
management of the raw material. Where there is no analogous raw material, the secondary material should be managed to minimize the potential for releases into the environment.
- Criterion 2: The secondary material provides a useful contribution to the recycling process or to a product of the recycling process and evaluating this criterion should include consideration of the economics of
the recycling transaction. The recycling process itself may involve reclamation, or direct reuse without reclamation.
- Criterion 3: The recycling process yields a valuable product or intermediate that is: (i) Sold to a third party; or (ii) Used by the recycler or the generator as an effective substitute for a commercial product
or as a useful ingredient in an industrial process.
- Criterion 4: The product of the recycling process:(i) Does not contain significant amounts of hazardous constituents that are not found in analogous products; and (ii) Does not contain significantly elevated
levels of any hazardous constituents that are found in analogous products; and (iii) Does not exhibit a hazardous characteristic that analogous products do not exhibit.
Conforming Changes
The revised definition of solid waste will cause several other portions of regulations to become obsolete or to require conforming changes. EPA discusses and/or proposes
potential conforming changes to the following existing regulations.
- 261.2(e)(1)(iii) - regarding solid wastes recycled by being returned to the original process from which they were generated without first being reclaimed or land disposed. This is proposed to be removed.
- 261.4(a)(6) - regarding pulping liquors reclaimed in a pulping liquor recovery furnace and then reused in pulping process. This is proposed to be removed.
- 261.4(a)(7) - regarding spent sulfuric acid used to produce virgin sulfuric acid. This is proposed to be modified.
- 261.4(a)(8) - for secondary materials that are reclaimed and returned to the original process or processes in which they were generated where they are reused in the production process. This is proposed to be
removed.
- 261.4(a)(9) - regarding spent wood preserving solutions that have been reclaimed and are reused for their original intended purpose. This is proposed to be modified.
- 261.4(a)(10) - regarding certain types of hazardous wastes that are recycled to coke ovens or to produce coal tar. This is proposed to be modified.
- 261.4(a)(11) - regarding conditional exclusion of non-wastewater splash condenser dross residue from treatment of K061. This is proposed to be modified
- 261.4(a)(13) - regarding excluded scrap metal (processed scrap metal, unprocessed home scrap metal, and unprocessed prompt scrap metal) being recycled. This is proposed to be modified.
- 261.4(a)(14) - regarding shredded circuit boards. This is proposed to be modified.
- 261.4(a)(17) - regarding spent materials generated within the primary mineral processing industry. This is proposed to be modified.
- 261.4(a)(19) - regarding spend caustic solutions from petroleum refining liquid treating processes used as a feedstock to produce cresylic or naphthenic acid. This is proposed to be modified.
- 260.30(b) and 260.31(b) - regarding variances from classification as solid waste if materials are reclaimed under the exclusion in 261.2(g). This is proposed to be modified.
Enforcement
EPA proposes that if material fails to be consistently managed within the boundaries of the 261.2(g) exclusion, the material is not excluded and is a hazardous waste for
Subtitle C purposes from the time the generator first generated it. Therefore, each person who manages a hazardous secondary material that loses its exclusion would have to manage it consistently with hazardous waste
management requirements from the point when the material was first generated, regardless of whether the person is the one who actually caused the loss of the exclusion.
State Authority and Interstate Transport
According to preamble discussion, this proposal is less stringent than the current federal program so states are not required to adopt these changes, and
materials may be regulated differently from state to state. However, this logic is questionable in light of the Court decision which held secondary materials generated and recovered in the same industry are not
wastes. Thus it would seem that this would also be outside the scope of States to regulate as hazardous waste.
