NR 661.0004(1)(x)5.b.
b. Prior to arranging for transport of hazardous secondary material to a reclamation facility where the management of the hazardous secondary material is not addressed under a RCRA part B permit or interim status standards, the hazardous secondary material generator shall make reasonable efforts to ensure that each reclaimer intends to properly and legitimately reclaim the hazardous secondary material and not discard it, and that each reclaimer will manage the hazardous secondary material in a manner that is protective of human health and the environment. If the hazardous secondary material will be passing through an intermediate facility where the management of the hazardous secondary material is not addressed under a RCRA part B permit or interim status standards, the hazardous secondary material generator shall make contractual arrangements with the intermediate facility to ensure that the hazardous secondary material is sent to the reclamation facility identified by the hazardous secondary material generator, and the hazardous secondary material generator shall perform reasonable efforts to ensure that the intermediate facility will manage the hazardous secondary material in a manner that is protective of human health and the environment. Reasonable efforts shall be repeated at a minimum of every 3 years for the hazardous secondary material generator to claim the exclusion and to send the hazardous secondary material to each reclaimer and any intermediate facility. In making these reasonable efforts, the generator may use any credible evidence available, including information gathered by the hazardous secondary material generator, provided by the reclaimer or intermediate facility, or provided by a third party. The hazardous secondary material generator shall affirmatively answer all of the following questions for each reclamation facility and any intermediate facility:
1) Does the available information indicate that the reclamation process is legitimate pursuant to s.
NR 660.43? In answering this question, the hazardous secondary material generator may rely on their existing knowledge of the physical and chemical properties of the hazardous secondary material, as well as information from other sources, such as the reclamation facility and audit reports, about the reclamation process.
2) Does the publicly available information indicate that the reclamation facility and any intermediate facility that is used by the hazardous secondary material generator notified the appropriate authorities of hazardous secondary material reclamation activities pursuant to s.
NR 660.42 and have they notified the appropriate authorities that the financial assurance condition is satisfied per subd. 6. f.? In answering these questions, the hazardous secondary material generator may rely on the available information documenting the reclamation facility's and any intermediate facility's compliance with the notification requirements per s.
NR 660.42, including the requirement specified in s.
NR 660.42 (1) (e) to notify the department whether the reclaimer or intermediate facility has financial assurance.
3) Does publicly available information indicate that the reclamation facility or any intermediate facility that is used by the hazardous secondary material generator has not had any formal enforcement actions taken against the facility in the previous 3 years for violations of the RCRA hazardous waste regulations and has not been classified as a significant noncomplier with RCRA Subtitle C? In answering this question, the hazardous secondary material generator may rely on the publicly available information from EPA or the department. If the reclamation facility or any intermediate facility that is used by the hazardous secondary material generator has had a formal enforcement action taken against the facility in the previous 3 years for violations of the RCRA hazardous waste regulations and has been classified as a significant non-complier with RCRA Subtitle C, does the hazardous secondary material generator have credible evidence that the facilities will manage the hazardous secondary material properly? In answering this question, the hazardous secondary material generator may obtain additional information from EPA, the department, or the facility itself that the facility has addressed the violations, the facility has taken remedial steps to address the violations and prevent future violations, or that the violations are not relevant to the proper management of the hazardous secondary material.
4) Does the available information indicate that the reclamation facility and any intermediate facility that is used by the hazardous secondary material generator have the equipment and trained personnel to safely recycle the hazardous secondary material? In answering this question, the generator may rely on a description by the reclamation facility or by an independent third party of the equipment and trained personnel to be used to recycle the generator's hazardous secondary material.
5) If residuals are generated from the reclamation of the excluded hazardous secondary material, does the reclamation facility have the licenses required, if any, to manage the residuals? If not, does the reclamation facility have a contract with an appropriately licensed facility to dispose of the residuals? If not, does the hazardous secondary material generator have credible evidence that the residuals will be managed in a manner that is protective of human health and the environment? In answering these questions, the hazardous secondary material generator can rely on publicly available information from EPA or the department, or information provided by the facility itself.
