Final answer:
An operation must obtain a variance from the regulatory authority if they want to deviate from standard regulations or requirements.
Step-by-step explanation:
If an operation needs to obtain a variance from the regulatory authority, it means that they are seeking permission or an exception to deviate from the standard regulations or requirements set by the authority. This could be necessary when the operation wants to implement a change or activity that is not allowed by default. Examples of situations where an operation might require a variance include building a structure taller than permitted, operating outside of specified hours, or using materials that are not typically allowed.
