What does DOL regulate in the context of SC wastewater plants?

• A. Environmental discharge limits
• B. Equipment efficiency standards
• C. Safety standards for workers
• D. Public health compliance

Answer: (C)

DOL focuses on protecting workers by setting and enforcing safety standards in the workplace. In wastewater plants, the relevant function is OSHA within DOL, which creates requirements for training, hazard communication, personal protective equipment, and safe procedures to guard against risks like chemical exposures, confined-space entry, electrical and mechanical hazards, and other job-site dangers. The other options deal with environmental limits, energy/equipment standards, or public health requirements, which are handled by environmental, energy, or health agencies—not DOL.
