What does CFR stand for in regulatory documents?

CFR stands for Code of Federal Regulations. This is an essential collection of the general and permanent rules published in the Federal Register by the executive departments and agencies of the federal government of the United States. The CFR organizes the regulations based on subject matter, allowing for easier navigation and reference to federal laws. It serves as a comprehensive resource for understanding various regulatory requirements across numerous sectors, including environmental protections, public health, and safety standards, making it crucial for professionals in fields such as water quality and environmental science.

While the other options might sound plausible, they do not accurately reflect the established terminology used in U.S. regulatory context. The Code of Federal Regulations is specifically designated as CFR, and understanding this terminology is key for anyone engaging in regulatory compliance or related work.
