July 2, 2015 Work Plan For ACM Abatement And Lead -Containing Page 6 22241 McClellan Road, Cupertino, California 3.2 Consultant Monitoring, Reporting, and Clearance Criteria The Consultant will be the Consultant representing the owner at the Site. It will provide the abatement monitoring, work area inspection, and final visual inspection of the asbestos abatement and paint stabilization areas. Envirocom will collect air clearance samples for laboratory testing. 3.3 Consultant's Daily Oversight Duties During the asbestos abatement and paint stabilization work, the Consultant will provide daily oversight and monitoring of the contractor's work. The Consultant's on -Site representative will be a CAC or Certified Site Surveillance Technician (CSST). The project will be supervised by a CAC and CDPH certified Lead Project Monitor. Prior to starting the abatement work, the Consultant will verify that the abatement contractor has completed all pre -work submittals and workers possess valid training and medical certifications for the project. The Consultant will also perform regular examination of the containments, engineering controls and work practices of the abatement contractor to ensure that the containments will remain intact , and controls are effective, and the work practices are minimizing creation of visible dust. The Consultant will maintain a daily log of Site activities including sketches of the work areas and air sample locations. 3.4 Visual Clearance Criteria As part of clearance process for all asbestos abatement and paint stabilization work, the Consultant will perform final visual inspection. The inspection will include a complete walkthrough of the work areas prior to application of sealing or bridging encapsulants. Visual clearance of the work areas are achieved when removal of all identified ACMs and debris are complete, and all deteriorated/pilling painted surfaces are stabilized. 3.5 Asbestos Air Clearance Criteria Final clearance phase contrast microscopy (PCM) sampling shall be conducted, after the visual inspections by Envirocom. A minimum of 1,250 liters to a maximum of 3,850 liters of air shall be collected from each containment One clearance air sample will be collected from each containment area.
