A separate letter shall be mailed by the contractor to the Fire Department within 48 hours of the completion of permitted work stating that the removal of asbestos is complete and that all removed fireproofing has been replaced, including all required respray, in a manner approved by the Department of Building and Safety. This letter shall be signed by the contractor or by any subcontractor performing the respray. If the contractor does not perform the respray, or cause the respray to be performed by a subcontractor, the contractor shall forward a letter to the Fire Department within 48 hours of the completion of the work stating that the removal of the asbestos is complete; that all required fireproofing has been replaced, if applicable, excluding respray; and stating the name of the contractor hired to do the respray. If the name of the contractor hired to do the respray is unavailable, the letter shall so state.
