Which organizational body typically governs local sewer-use ordinances?

Local sewer-use ordinances are generally governed by the city or municipal government because these entities are responsible for managing and regulating local infrastructure, including wastewater treatment and sewer systems. These ordinances are specific to each locality and help ensure the proper handling of sewage to protect public health, safety, and the environment. Since sewer systems are usually a part of a municipality's services, local governments create and enforce regulations tailored to their specific communities.

In contrast, the Environmental Protection Agency primarily focuses on national standards and regulations that set overarching guidelines for environmental protection, but does not dictate local sewer policies. The state environmental department has a broader regulatory role across the state and works to ensure compliance with state and federal laws but does not govern local ordinances directly. Similarly, water quality control boards typically oversee water quality standards and regulations at a state level rather than managing local sewer-use ordinances. Thus, the role of city or municipal governments in local sewer-use ordinances underscores the localized nature of wastewater management.
