Which federal conservation program's regulations can be found at 40 CFR 240-282?

The Resource Conservation and Recovery Act (RCRA) is the correct choice because it specifically governs the management and disposal of hazardous waste. The regulations pertaining to RCRA are detailed in Title 40 of the Code of Federal Regulations (CFR) from sections 240 through 282. These regulations cover a wide range of topics related to waste management, including the identification of hazardous waste, standards for waste treatment, storage, and disposal, as well as guidelines for waste minimization and recycling.

The other federal conservation programs mentioned in the options do not align with the CFR sections 240-282. The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as the Superfund law, is focused on the cleanup of hazardous waste sites and is found under different sections of the CFR. The National Environmental Policy Act (NEPA) is concerned with environmental review processes and impact statements, while the Clean Water Act (CWA) deals primarily with water quality and pollution regulations, none of which are detailed under the specified CFR sections for RCRA. Therefore, the alignment of RCRA's regulations with the correct CFR range confirms its appropriateness as the answer.
