maintained throughout the subsequent waste handling and disposal procedures.
• Vacuum cleaners equipped with HEPA filters shall be used to collect dust and debris
containing ACM.
The contractor shall remove all wastes generated from the abatement activities as
asbestos containing waste and in accordance with all applicable Local, State, and
Federal regulations. Upon achieving visual clearance from the Consultant,
encapsulating material shall be applied to all surfaces prior to final air clearance
sampling.
3.1 Personal Protective Equipment
Personal protective equipment (PPE) shall consist of full body disposable protective
suit, steel -toed boots, gloves, safety glass or goggles, hard hat (as required), and
respirator. Respirators shall offer at least the protection of 1/2-face negative pressure
respirators equipped with HEPA filters. Unless fiber concentrations require greater

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.

END OF SECTION
4.0 PAINT STABILIZATION PROCEDURES
Lead -based paint (LBP) and lead -containing paint (LCP) have been identified at the
Site. Abatement of LBP and LCP is not required for demolition projects. However, to
minimize worker's exposure, proper hazardous waste management, and preventing soil
contamination, stabilization of deteriorated painted surfaces are required prior to
demolition work.
Precautions should be taken to minimize lead dust generation and exposure and to
avoid accumulation of large quantities of lead -containing wastes.
4.2 Visual Clearance Criteria
After completion of paint stabilization and removal of waste, the contractor shall clean
the regulated area, and notify the Consultant for final visual inspection.
4.2 Waste Disposal
Packing, labeling, transporting, and disposing of hazardous waste shall comply with
applicable Cal/EPA regulations under 22 CCR, and California Health and Safety Code.
A "Waste Manifest" shall be completed for disposal of hazardous waste. The
transported waste shall posses a valid EPA generator ID number. The Contractor shall
notify the owner at least 24 hours prior to the time that the manifest is required to be
signed by the owner.
The contractor shall be responsible for conducting an appropriate hazardous waste
determination for the wastes containing lead. Profiling lead in wastes requires both
California as well as Federal hazardous waste characterization. California has two
regulatory threshold for wastes contaminated with lead, Total Threshold Limit
Concentration (TTLC) and Soluble Threshold Limit Concentration (STLC). The
regulatory limits for lead are 1000 mg/kg and 5.0 mg/L, respectively. Lead wastes
consider hazardous under Federal regulations when concentration of lead is equal or
exceed 5.0 mg/L using Toxicity Characteristic Leaching Procedure (TCLP) procedure.
The contractor shall use a State -certified analytical laboratory for the above analytical
procedures.
