A more thorough explanation:

A proposed regulation is a draft administrative rule or order that is circulated among interested parties for comment. It is a preliminary version of a regulation that has not yet been finalized or put into effect.

For example, the Environmental Protection Agency (EPA) may propose a new regulation that would limit the amount of pollution that factories can emit into the air. The proposed regulation would be published in the Federal Register and interested parties, such as industry groups and environmental organizations, would have the opportunity to provide feedback and comments on the proposal before it becomes final.

Proposed regulations are an important part of the regulatory process because they allow for public input and feedback before a regulation is finalized. This helps to ensure that regulations are effective, fair, and reasonable.
