Which document defines the responsibilities of the ORC?

The correct choice provides clarity on the duties and responsibilities of the Operator of Record (ORC) regarding the operation of wastewater systems. The Water Pollution Control System Certification Commission regulations explicitly outline the requirements for certifications and permits for individuals responsible for overseeing the operation and maintenance of wastewater systems, including septic systems.

By establishing these regulations, the commission ensures that ORCs are held to a standard that promotes public health and environmental protection. This includes guidelines around monitoring system performance, ensuring compliance with state and federal regulations, and maintaining proper records of system inspections and maintenance activities.

In contrast, local health guidelines may offer general operational recommendations but do not specifically delineate the legal responsibilities of the ORC. Similarly, while a septic tank operation manual provides practical guidance on the functioning of such systems, it does not address the regulatory framework that defines the ORC's duties. State building codes cover construction standards and safety, which are vital but do not specifically detail the roles and responsibilities unique to the ORC in wastewater management.
