Which regulatory body governs 314 CMR 12:00 related to sewer systems and wastewater treatment facilities?

The governing body for 314 CMR 12:00, which pertains to sewer systems and wastewater treatment facilities in Massachusetts, is the Division of Water Pollution Control. This division operates under the Massachusetts Department of Environmental Protection and is specifically concerned with the regulation of water quality and pollution management. Its responsibilities include overseeing the design, construction, operation, and maintenance of wastewater treatment facilities, ensuring compliance with state and federal water quality standards. The regulations outlined in 314 CMR 12:00 establish requirements for managing discharges to water bodies, thus ensuring that wastewater is treated effectively to protect public health and the environment.

In this context, the other choices represent different divisions that focus on air quality and solid waste management, which do not directly handle wastewater treatment regulations. The Environmental Protection Agency, while it plays a crucial role in national water regulations, is not the governing body for this specific state regulation.
