Completed notifications, with all documentation and associated fees, must be submitted at least: 10 working days (two calendar weeks) before a demolition, including buildings where no asbestos is present. 10 working days (two calendar weeks) before a renovation operation if the amount of asbestos material stripped or removed is greater than 160 square feet on facility components, or 260 linear feet on pipes, or 35 cubic feet where the amount cannot be measured. One day before demolition if the building has been declared structurally unsound and in danger of imminent collapse by a State or local governmental agency (a building official must make this determination). The 10-working-day notification period (two calendar weeks) does not begin until all required notification information, fees and asbestos survey documents are submitted. If mailed, the postmark will establish the beginning of the period.
