Which aspect of waste management involves regulations for both generation and disposal?

RCRA Subtitle C is the correct answer as it specifically governs the management of hazardous waste from its generation to its disposal. This section of the Resource Conservation and Recovery Act (RCRA) includes regulations that set forth standards for the treatment, storage, and disposal of hazardous waste as well as requirements for waste generators. It ensures that hazardous waste is handled safely and responsibly throughout its lifecycle, thereby protecting human health and the environment.

In contrast, other options focus on more limited aspects of waste management. For instance, Coal Ash Regulations primarily deal with the disposal and management of coal combustion residuals, while Solid Waste Management Policies cover broader aspects of solid waste but do not specifically target hazardous waste regulations. Environmental Assessment Procedures typically involve evaluating potential environmental impacts of proposed projects but do not directly regulate the generation and disposal of waste.
