Which group is typically responsible for enforcing pretreatment regulations?

The group responsible for enforcing pretreatment regulations is the Environmental Protection Agency (EPA). The EPA has the authority to establish and implement regulations to protect water quality under the Clean Water Act. This includes developing guidelines for pretreatment standards to regulate pollutants that industrial users discharge into municipal wastewater treatment systems.

While other groups may play important roles in environmental education, community advocacy, or even day-to-day operations of treatment facilities, the EPA is specifically tasked with enforcing federal regulations, ensuring compliance, and overseeing the implementation of pretreatment programs to safeguard public health and the environment.
