The 300-Foot Pipe Run and the 25-Square-Foot Transite Panel
A 1974 mill building is being renovated into offices. The owner's facilities manager plans one project: remove 300 linear feet of friable pipe insulation from the basement mechanical room and 25 square feet of transite panel from a boiler flue. The transite is in good condition and will be unscrewed and lowered, not sawed. The building is not a school. Demolition of an adjoining wing is scheduled for later, and the owner asks whether the 40 linear feet of pipe insulation in that wing can be left in place because the wing will be demolished. The contractor has not yet been selected. The manager wants to know what triggers federal and Maine notification, who must notify, and when. He also asks whether the transite counts toward the threshold and whether the demolition insulation can stay.
1. Does the 300-foot pipe removal require NESHAP notification? Does the 25 square feet of transite affect that analysis?
Read the worked answer
Yes. NESHAP requires notification for a renovation if the project will remove at least 160 square feet, 260 linear feet, or 35 cubic feet of RACM. The 300 linear feet of friable pipe insulation is RACM and exceeds the 260-linear-foot trigger, so the project is a regulated renovation. The transite does not change that conclusion. Transite is a category I nonfriable material; if it is unscrewed and lowered without sawing, sanding, or breaking, it is not RACM and its 25 square feet is below the 160-square-foot trigger anyway. The units are not added together or converted. But if the transite is cut or breaks, it becomes RACM and must be handled accordingly. Maine's Chapter 425 is more protective than NESHAP in several respects and requires a Maine-licensed contractor for abatement above the small-scale threshold; the owner should confirm Maine notification and licensing separately.
2. Who must submit the notification, when, and what happens if work starts early?
Read the worked answer
The owner/operator of the building is responsible for notification, though a contractor often prepares and submits it. NESHAP requires written notification at least 10 working days before the start of the renovation. In Maine, notification goes to the Maine DEP asbestos program, with the fee and the required project information: owner, contractor, supervisor, start and completion dates, amount and type of RACM, work practices, and waste disposal site. If the start date changes, the notification must be updated. Starting early without a valid notification exposes the owner and contractor to penalties and stop-work. The manager should not let schedule pressure compress the notification timeline; ten working days means ten business days, not ten calendar days.
3. Can the 40 linear feet in the wing scheduled for demolition be left in place? Explain.
Read the worked answer
No. The 40 linear feet in the wing slated for demolition cannot be left in place. NESHAP requires that all RACM be removed before demolition, regardless of whether the amount is below the renovation thresholds, because demolition will crumble the insulation and create regulated asbestos waste. The demolition notification must include the asbestos removal, and the removal must be completed under containment before the demolition begins. The owner should treat the removal as part of the abatement project, not as something the demolition contractor can handle by wetting during tear-down. If the wing is demolished first, the material becomes impossible to control.
