Oregon Construction Contractors (CCB) Practice Test

The correct answer is the DEQ, which stands for the Department of Environmental Quality. In Oregon, the DEQ is tasked with overseeing environmental protection laws and regulations, including the management and installation of septic systems. This agency ensures that septic systems are installed and maintained according to state health and environmental standards, which helps to protect water quality and public health.

The requirement for a Construction-Installation permit for these systems is grounded in the need to regulate how waste is managed in both residential and small commercial settings, preventing contamination of surface and groundwater. The DEQ establishes the criteria and processes for obtaining these permits, ensuring that installations meet specific environmental standards.

In contrast, the EPA primarily focuses on national environmental regulations but does not handle local permitting directly. OSHA, the Occupational Safety and Health Administration, is concerned with workplace safety and health, while the CDC, the Centers for Disease Control and Prevention, deals with public health but does not regulate septic system installations.
