Which statement correctly describes the regulatory focus of 40 CFR 264 compared to 40 CFR 265?

• A. 264 applies to interim status facilities; 265 applies to permitted facilities
• B. 264 applies to permitted facilities; 265 applies to facilities with interim status
• C. 264 is for transporters; 265 is for generators
• D. 264 is for state agencies; 265 is for federal agencies

Answer: (B)

The main idea here is that these two parts of the CFR govern facilities at different stages of the RCRA authorization process. 40 CFR 264 contains the final, permit-based standards that facilities must meet once they have obtained a RCRA permit. These are the comprehensive requirements tied to the approved permit, covering design, operation, closure, groundwater monitoring, contingency planning, financial assurance, and other long‑term controls. 40 CFR 265, by contrast, addresses interim status. It applies to facilities that have submitted a permit application and are operating while awaiting a final permit. The interim status provisions establish the protections and conditions that apply during that interim period, often with a more limited or transitional scope than the full permit standards in 264. So the correct interpretation is that 264 focuses on permitted facilities, while 265 focuses on facilities with interim status. The other options mix up which regulation applies to interim status versus permitted operations and are not accurate descriptors of these parts.
