56-4.12 Unsatisfactory clearance air sample results.
If the regulated abatement work area clearance air sampling results are unacceptable, the following requirements apply:
(a) If the results of the inside work area group of air samples are unsatisfactory, recleaning of regulated abatement work area surfaces using wet methods, followed by another drying time period and then collection and analysis of an additional full set (both inside and outside work area samples) of clearance air samples is required (see section 56-9.2 of this Part).
(b) If only the results of the outside work area group of air samples is unsatisfactory, clean-up of surfaces outside of the regulated abatement work area using HEPA-vacuums and wet-cleaning methods shall be performed prior to collection and analysis of an additional group of outside work area clearance air samples as required by section 56-9.2 of this Part.
(c) This recleaning/clean-up and sampling process shall be repeated until satisfactory clearance air sampling results have been achieved for all asbestos project non-exempt regulated abatement work areas throughout the entire work site.
