Right-to-know information is provided by which document?

• A. Material Safety Data Sheet
• B. NPDES permit
• C. sewer ordinance
• D. Clean Water Act

Answer: (C)

Right-to-know information in the context of a wastewater system is about what the public can learn from official regulations and records about how the system is used, what is allowed to go into the sewer, and how the system is managed. A sewer ordinance is the local regulation that communicates these details directly to the community. It lays out prohibited discharges, reporting and notification requirements (for spills or overflows), user classifications, and how residents and businesses can access information about enforcement actions and system rules. In short, it’s the local document designed to inform the public about the sewer system’s operation and safeguards, making it the best source for right-to-know information.

While a Material Safety Data Sheet provides hazard information about specific chemicals to workers, and an NPDES permit or the Clean Water Act outline federal requirements and permit conditions, they don’t serve as the public-facing vehicle for right-to-know under a community’s sewer system like a sewer ordinance does.
