Which governmental agency enforces regulations regarding asbestos handling and disposal?

The Environmental Protection Agency (EPA) is the correct answer because it is the primary federal agency responsible for enforcing regulations concerning environmental practices, which includes the handling and disposal of asbestos. The EPA sets standards and guidelines to protect human health and the environment from the hazards associated with asbestos exposure. This agency develops regulations to ensure that asbestos is managed safely and effectively during construction, renovation, and demolition activities, which is crucial due to the serious health risks posed by asbestos, including lung cancer and mesothelioma.

While OSHA does play a role in regulating workplace safety and has specific standards regarding asbestos exposure in the workplace, its focus is more on occupational safety rather than environmental regulations. The Department of Health and Human Services is primarily involved in public health initiatives and does not directly enforce regulations regarding environmental hazards like asbestos. The Federal Aviation Administration is focused on aviation safety and regulation, which does not pertain to asbestos handling or disposal. Therefore, the comprehensive responsibilities of the EPA in the context of environmental safety make it the correct choice in this scenario.
