Final answer:
Public hearings for temporary regulations are typically held for significant regulations, but may not always be required. Temporary regulations are often implemented quickly and may not require public hearings. Public input can still be sought through other means.
Step-by-step explanation:
Public hearings for temporary regulations are not always required. In the regulatory process, public hearings are typically held for significant regulations where there may be a significant impact on the public. Temporary regulations, on the other hand, are often implemented quickly and are intended to address urgent issues or situations. As a result, public hearings may not be necessary for temporary regulations. However, it is important to note that public input and comments may still be sought through other means such as written statements or consultations.
