The pre-blast survey offer applies only under what condition?

• A. Always
• B. Only when the standard table of distance is exceeded
• C. Only when the owner requests
• D. Only in urban areas

Answer: (B)

The key idea is that a pre-blast survey is used to document the condition of neighboring properties when there’s potential risk identified by the blasting plan. The offer is made only if the proposed blast would exceed the distances listed in the standard Table of Distances. When the blast stays within those distances, there’s no required pre-blast survey because the risk level is considered acceptable. It isn’t about always offering it, about owner requests, or about being restricted to urban areas—the trigger is surpassing the standard distance threshold.
