(a) Owners or operators of hazardous waste management facilities, who qualify for interim status pursuant to 40 Code of Federal Regulation Part 270, Subpart G, who have continuing authority to store, process, and/or dispose of hazardous waste pursuant to Chapter 335 of this title (relating to Industrial Solid Waste and Municipal Hazardous Waste), and who filed a Part A permit application pursuant to 40 Code of Federal Regulations §270.10 shall file a revised Part A application with the executive director for any of the following changes during interim status:
  (1) new hazardous wastes not identified in the original application are stored, processed or disposed of at the facility;
  (2) increases in the design capacity of processes used at the facility occur;
  (3) changes in the processes for management of the waste occur or additional processes are added;
  (4) changes in the ownership or operational control of a facility are made; or
  (5) newly regulated units for the storage, processing, or disposal of hazardous waste are added.
(b) The purpose of this section is to delineate requirements for filing a revised application, not to authorize any changes in facility operation. Changes in facility operations will be reviewed and approved by the executive director. In deciding whether to approve the proposed change, the executive director may consider the requirements set forth in 40 Code of Federal Regulations §270.72. For changes in the ownership or operational control of a facility, the new owner or operator shall submit a revised Part A permit application no later than 90 days prior to the scheduled change and shall also comply with the requirements set forth in 40 Code of Federal Regulations §270.72(d). A permit will be required for the operation of an above-grade landfill not described in a Part A application filed pursuant to §335.43 of this title (relating to Permit Required) prior to the effective date of this section.
(c) Except as specifically allowed under this subsection, changes listed under subsection (a) of this section may not be made if they amount to reconstruction of the hazardous waste management facility. Reconstruction occurs when the capital investment in the changes to the facility exceeds 50% of the capital cost of a comparable entirely new hazardous waste management facility. If all other requirements are met, the following changes may be made even if they amount to a reconstruction:
  (1) changes made solely for the purposes of complying with the requirements of 40 Code of Federal Regulations (CFR) §265.193 for tanks and ancillary equipment;
  (2) if necessary to comply with federal, state, or local requirements, changes to an existing unit, changes solely involving tanks or containers, or addition of replacement surface impoundments that satisfy the standards of §3004(o) of the Resource Conservation and Recovery Act (RCRA), as amended;
  (3) changes that are necessary to allow owners or operators to continue handling newly listed or identified hazardous wastes that have been stored, processed, or disposed of at the facility prior to the effective date of the United States Environmental Protection Agency (EPA) regulation establishing the new listing or identification;
  (4) changes during closure of a facility or of a unit within a facility made in accordance with an approved closure plan;
  (5) changes necessary to comply with an interim status corrective action order issued by the EPA under §3008(h) of the RCRA, as amended, or other federal authority, by an authorized State under comparable state authority, or by a court in a judicial proceeding brought by the EPA or an authorized State, provided that such changes are limited to the storage, processing, or disposal of solid waste from releases that originate within the boundary of the facility;
  (6) changes to store or process, in tanks, containers, or containment buildings, hazardous wastes subject to land disposal restrictions imposed by 40 CFR, Part 268 or by §3004 of the RCRA, provided that such changes are made solely for the purpose of complying with 40 CFR, Part 268 or §3004 of the RCRA, as amended;
  (7) addition of newly regulated units under subsection (a)(5) of this section; and
  (8) changes necessary to comply with standards under 40 CFR Part 63, Subpart EEE--National Emission Standards for Hazardous Air Pollutants From Hazardous Waste Combustors.
