FACILITY REMEDIATION - ASBESTOS AND LEAD IMPACT

PART 1 - GENERAL

SUMMARY

A. The work of this section consists of asbestos and lead impact and lists environmental controls to be used during impact to asbestos containing materials (ACM), lead-based paint (LBP) and lead containing paint (LCP) during the renovation of the Grand Canyon Indian Gardens Pumphouses.

Scope items and requirements for asbestos and lead hazard management associated with LBP and lead-containing paint (LCP) are presented below in sections B through O.

B. The proposed improvements entail cutting into and drilling holes through wallboard that has been identified as Asbestos Containing Materials (ACM) and removing existing pipe materials that have been tested and confirmed to be coated with Lead Based Paint. The existing lead painted piping will be dismantled by unbolting the flanges, however there will be at least one location where the pipe will need to be cut, where it protrudes above the concrete floor of the pump station.

C. The Contractor shall take necessary reasonable measures to control air and water pollution by any material or equipment used during asbestos impact and lead hazard control activities.

D. Identified locations of ACM and LBP are contained in the HDR Asbestos and Lead-based Paint

Sampling Report dated Sept. 2016):

1. Asbestos Containing Materials;

a. North Pump House

(i) Wallboard behind fiberglass insulation along the interior south wall was tested and contained 12% Chrysotile asbestos.

(ii) Wallboard along the interior north wall was tested at 15% Chrysotile asbestos.

b. South Pump House

(i) In addition, the black tar and tan fibrous resinous material layers of the roof contain trace amounts of Chrysotile asbestos (less than 1%). Though this percentage of asbestos does not meet the definition of ACM, workers should be made aware of its presence.

E. The Contractor shall be responsible for the collection of personnel exposure samples for asbestos and lead in accordance with the Occupational Safety and Health Administration (OSHA) regulations.

F. If suspect ACM is encountered in wall or ceiling interiors in unanticipated locations, the unforeseen condition shall be documented and described, including location, extent and the quantity of suspect

ACM, and all immediate actions shall be taken for safety or housekeeping purposes. This information shall be immediately provided to the Industrial Hygienist (IH) and the Contracting Officer (CO).

3. Pre-clean all mechanical equipment, floors, and walls.

4. Install critical barriers. Seal off any penetration or entrances into the work area using one (1) layer of 6-mil. polyethylene sheeting and tape. Polyurethane sealant foam may be used for small penetrations.

5. Complete containment barriers as per specification.

6. Approval of worker decontamination system(s) and containment system shall be approved by

Competent Person prior to initiation of impact activities.

7. Upon completion of impact activities, the Contractor shall request final inspection of the work area by the Industrial Hygienist. All surfaces shall be thoroughly cleaned prior to this request.

8. Upon the work area being declared visually clean, air sampling of the work area shall occur for air clearance. All but critical barriers will be removed prior to sampling.

9. If air sampling indicates area clearance in accordance with specifications, the area will be declared clean and all remaining polyethylene, tape, debris, etc. shall be removed and bagged as asbestos contaminated waste.

10. Encapsulating agent shall be applied to edges of impacted ACM surfaces. Approval from the

Industrial Hygienist shall be obtained before applying encapsulant.

11. All asbestos waste must be adequately wet as defined in the EPA/NESHAP Guidance dated

December 1990. Per the EPA Guidance, “adequately wet” means to “sufficiently mix or penetrate with liquid to prevent the release of particles”. If visible emissions are observed coming from

ACM waste, then the material is not adequately wet. The absence of visible emissions is not sufficient evidence of being adequately wet. All abated materials, regardless of whether they are first stripped from their substrate, must be adequately wet prior to disposal.

LEAD CONTAINING PAINT WORK PRACTICES

A. The following sections describe protocols to be used for the various LCP impact tasks associated with this project that may generate airborne lead dust. After all personal protection is donned and controls are constructed; the task sequence shall be as follows:

1. Install critical barriers or other temporary systems as necessary to prevent dust and debris from leaving the work area.

2. Disassembling pipe systems where LCP/LBP is present.

a. Utilize wet methods to reduce dust generation. (water, penetrating solvent)

b. Unbolt flanges minimizing impact to the paint.

3. Cutting pipe at floor level where LCP/LBP is present.

a. Use needle gun or power scaling tool with HEPA filtered ventilation shroud to remove paint in cut area prior to cutting.

b. Chemical paint removers may be utilized with full knowledge of hazard and proper risk assessment.

ASBESTOS AIR MONITORING

A. Air samples for personal exposure to asbestos shall be collected by the Contractor. The services may be performed by the Industrial Hygienist. Asbestos in air samples shall be analyzed by an independent accredited laboratory.

B. Visible emissions will be controlled and shall be the standard for requiring additional workplace controls.

LEAD AIR AND SURFACE MONITORING

A. Air samples for personal exposure to lead shall be collected by the Contractor. The services may be performed by the Industrial Hygienist. Lead in air samples shall be analyzed by an independent accredited laboratory.

B. Visible emissions will be controlled and shall be the standard for requiring additional workplace controls.

ASBESTOS PROJECT DECONTAMINATION AND FINAL CLEARANCE

A. At the conclusion of the impact work, all surfaces in the work area should be thoroughly and completely HEPA-vacuumed. These surfaces include (but are not limited to) ceilings, walls, floors, doors, fixtures of any kind and appliances.

B. Wet wiping

1. Use Proper Wet Cleaning Procedures: At the conclusions of the impact work and after the first

HEPA vacuuming, all surfaces identified as requiring HEPA vacuuming earlier shall be thoroughly and completely washed with an amended water solution.

2. Change Cleaning Mixture Regularly: To avoid re-contaminating the area by using overly dirty water, users shall carefully follow surface area limits and change the cleaning mixture accordingly. Users must ensure that the dirty water does not re-contaminate the environment.

This dirty water is potentially hazardous and shall be treated accordingly

C. Final Inspection

1. After the final cleanup is complete, the final inspection will take place. Provide the Industrial

Hygienist (under contract with the Contractor) with 24-hour advanced notice of work areas prepared for final inspection. The objective of the inspection is to ensure and verify that no visible dust, dirt or debris is present.

2. At the conclusion of asbestos impact activities, final clearance air samples for asbestos will be collected in each asbestos impact area. The Industrial Hygienist shall collect clearance air samples for PCM analysis. If the air samples do not meet the post-impact standard of 0.010 f/cc, the work area will be re-cleaned until acceptable air levels are achieved.

3. At the conclusion of LCP/LBP impact activities, final clearance surface dust wipe samples for

Lead shall be collected in each Lead impact area. The Industrial Hygienist shall collect clearance dust wipe samples for Total Lead analysis. If the dust wipe samples of the floor do not meet the post-impact standard of 40 µg/ft2, the work area shall be re-cleaned until acceptable levels are achieved.

RE-ESTABLISHMENT OF THE WORK AREA AND SYSTEMS

A. Re-establishment of the work area to general access shall only occur following the completion of clean up procedures and/or after clearance sampling has been performed and documented to the satisfaction of Industrial Hygienist.

B. The Industrial Hygienist shall visually inspect the work area for any remaining visible residues.

Evidence of contamination shall necessitate additional cleaning and additional air monitoring.

Following satisfactory clearance of the work area, remaining polyethylene barriers may be removed and disposed of as asbestos-contaminated waste.

C. Upon successful completion of the final sampling, the barriers shall be disposed of as ACM. Removal of critical barriers and equipment shall be conducted using appropriate PPE.
