Final answer:
In response to a locate request, most underground utilities need to be located and marked except for some that may not require location depending on the type of request and local laws. The exact facilities that are exempt can only be determined by referring to specific jurisdiction rules.
Step-by-step explanation:
When a locate request is received, it typically pertains to identifying and marking the underground utilities before digging or construction work starts to prevent damages and ensure safety. This process is crucial for liability and safety reasons. Utilities such as gas, water, electricity, telecommunications, and sewage are generally marked. However, the question implies there are certain facilities that would not need to be located under a specific request. Since the facilities not requiring location would depend on the type of request and jurisdiction, without more context it is not possible to determine which facilities wouldn't need to be located. It is important for those who are involved in construction or excavation to always check with their specific local governing laws and requirements.
