Yes, size and volume constraints exist on the amount of asbestos that can be disturbed or removed during any single small-scale, short-duration project. Unit I.A.8 of Appendix C to Subpart E in 40 CFR part 763 provides some useful guidance about how to understand small-scale, short-duration activities. For example, small-scale, short-duration repair or removal work should fit into a single glove bag (for removal of asbestos-containing thermal system insulation) or a single prefabricated mini-enclosure (for repairs to small amounts of friable asbestos-containing material only if they are required in the performance of maintenance-activities that are not intended solely to be asbestos-abatement actions).
