FERC Upland Erosion Control, III-H For all properties with residences located within 50 feet of construction work areas, project sponsor shall, except:

Question 91:
This question asks to identify which action is not a requirement for project sponsors on properties with residences located within 50 feet of construction work areas, according to FERC Upland Erosion Control, III-H. We are looking for the "except" clause.

Let's evaluate each option based on typical FERC environmental compliance requirements for pipeline construction near residences:

• a) avoid removal of mature trees and landscaping within the construction work area unless necessary for safe operation of construction equipment, or as specified in landowner agreements: This is a standard environmental and aesthetic protection measure. Project sponsors are generally required to minimize disturbance to existing landscaping near residences. This is a required action.
• b) fence the edge of the construction work area for a distance of 100 feet on either side of the residence: While fencing is typically required for safety and to delineate work areas near residences, the specific distance of "100 feet on either side" is a very precise detail. FERC regulations often require fencing, but the exact footage can vary or might be stated more generally (e.g., "fence the work area adjacent to residences"). This specific, prescriptive distance makes it a potential candidate for the "except" clause, as it might not be a universal requirement as stated.
• c) notify residence owner of 24 hours prior to blasting within 50 feet of building with cistern: Blasting is a high-impact activity that can cause damage and disturbance. Prior notification to residents, especially those with sensitive structures like cisterns, is a critical safety and courtesy requirement. This is a required action.
• d) restore all lawn areas and landscaping immediately following clean-up operations, or as specified in landowner agreements: Prompt restoration of disturbed areas, especially lawns and landscaping near residences, is a fundamental part of environmental mitigation and good landowner relations. This is a required action.

Given that options a, c, and d represent common and essential environmental and safety practices near residences, option b, with its highly specific distance requirement for fencing, is the most likely item that might not be a universal or exact requirement as stated in FERC's Upland Erosion Control, III-H, or it might be a misstatement of the actual requirement.

The final answer is $\boxed{\text{b) fence the edge of the construction work area for a distance of 100 feet on either side of the residence}}$
