Which regulatory part should be researched for treatment and disposal standards for hazardous WMM?

The correct option focuses on 40 CFR Parts 260 through 270, which are specifically designed to address hazardous waste management. These parts outline the necessary regulations related to the identification, treatment, and disposal of hazardous waste materials, including Waste Military Munitions (WMM). This set of regulations provides the framework that governs how hazardous wastes must be managed, ensuring compliance with federal environmental standards aimed at protecting public health and the environment.

These regulations encompass several critical aspects, including the criteria for classifying waste, the standards for generators of hazardous waste, and the requirements for waste treatment, storage, and disposal facilities. Adhering to these guidelines is crucial for organizations dealing with hazardous WMM to ensure safe and compliant operations.

The other options pertain to different regulatory provisions that do not directly address the treatment and disposal standards for hazardous waste. The range of parts from 190 to 200, 210 to 220, and 280 to 290 address other environmental and operational aspects, but they do not specifically focus on the hazardous waste management protocols outlined in 40 CFR Parts 260 through 270.
