LEAD BASE PAINT (LBP) ABATEMENT, REMOVAL, AND DISPOSAL

PART 1 GENERAL

1.1 GENERAL INFORMATION

This section covers the sampling, removal and disposal of lead-based paint (LBP) from surfaces containing lead-based paint, as identified by the Government and verified by the Contractor. The sampling, removal and disposal of LBP is only that which is necessary to facilitate demolition of the elevator. Paint removal is intended to be accomplished prior to cutting, and only in those areas where cutting of the elevatorin pieces is necessary for shipping. Metal surfaces on elevator equipment described in this contract contain lead-based paint (LBP). An inventory of metal surfaces has not been completed. Painted metal surfaces are assumed to contain LBP. It is the responsibility of the Contractor to assure that coated metal surfaces are properly identified for LBP content and that no work proceeds on LBP surfaces without proper LBP abatement and removal controls. Contractor will remove LBP only where it is necessary to avoid airborne lead or where mechanical removal will result in paint chips being dispersed uncontrolled. To the maximum extent possible, items which will be taken out of service and removed for disposal, must be recycled as scrap metal without having LBP paint removed. LBP removal required both at the site and off-site and disposal must be in accordance with the approved LBP Management Plan. Coordination must be required between the Project and Contractor in determining all areas requiring LBP removal. Contractor must use paint removal and collection methods such as paint strippers to the maximum extent practical.

(1) Interior LBP Control Area requirements: NOT USED

(2) Exterior LBP Control Area requirements: Where the construction of a contained LBP Control Area is impractical, a roped-off perimeter must be installed 6 meters (20-feet) from and around the area where the LBP handling procedures are performed and other requirements for LBP control areas must be maintained.

Personnel monitoring of airborne concentrations must be conducted in adjacent areas, during the work shift, in accordance with 29 CFR 1926.62. Air monitoring outside of the roped-off perimeter must be conducted as specified. Airborne concentrations must not exceed specified levels.

f. Personnel Decontamination Unit Procedures. Decontamination units must be constructed when required for the LBP abatement and removal procedures. Materials fabricated or delivered to the site before the shop drawings have been returned or delivered to the site before the shop drawings have been returned to the Contractor will be subject to rejection by the Contracting Officer. Specifications and drawings of portable prefab units, such as a trailer unit, if utilized, must be submitted for review and approval before start of LBP work. Submittal must include, but not be limited to, a floor plan layout showing dimensions, materials, sizes, thicknesses, plumbing, and electrical outlets. Access between contaminated and uncontaminated rooms or areas must be through an airlock. Access between any two rooms or room and trailer within the decontamination unit must be through a plastic sheeting contained doorway. A separate equipment decontamination unit must be provided. Each work area must have an emergency exit. The personnel decontamination unit's clean room must be the only means of entrance and exit, except for emergencies, from the LBP control area.

Materials must exit the LBP control area through the equipment decontamination area.

g. Clean Room Procedures. The clean room must have only one exit to non-contaminated areas of the LBP work area in the project powerhouse building. An airtight seal must be constructed of polyethylene between the clean room and the rest of the building. Surfaces of the clean room must be protected with sheet polyethylene. A temporary unit, with a separate, equipment decontamination, locker room, and a clean locker room, must be provided for personnel who are required to wear whole body protective clothing. One locker must be provided in each locker room for each LBP abatement and removal worker, and each Contractor's representative. Lead-free personal clothing and shoes must be kept in the clean locker. Hand wash station/showers must be located between the equipment decontamination locker room and the clean locker room, and employees must wash or shower before changing into personal clothes. An adequate supply of clean disposable towels must be provided. LBP contaminated work clothing must be cleaned. Clean rooms must be physically attached to the LBP control area for areas inside the building.

h. Hand Wash Station/Shower Room Procedures. An operational shower and hand washing station must be provided between the work area and the clean changing room. Workers must wash and/or shower before entering the clean changing room. The shower room must be separated from other rooms by air-tight walls fabricated of polyethylene sheeting. Water must be hot and cold or warm. Shower heads and controls, soap dish, continuing supply of soap, and clean towels must be provided. The shower must be maintained in a sanitary condition. Wastewater must be

SECTION 02 83 20.00 25 Page 16 pumped to drain and through waste- water filters that meet state and local requirements. These filters must be located inside the shower unit and filters must be changed regularly according to manufacturers' specifications. Spent filters must be discarded as LBP contaminated waste.

i. Equipment Decontamination Unit Procedures. The Equipment Decontamination Unit must be used for removal of equipment and materials from the LBP control area, and must include a wash room and holding room. The unit must be constructed of wood or metal framing material and polyethylene sheeting. Workers must not enter or exit the LBP control area through the Equipment Decontamination Unit. A wash down station, consisting of an enclosed shower unit, must be located in the work area outside the Wash Room. The wash down station must be used to clean equipment, bags and containers. Bagged or containerized LBP wastes must be passed from the work area and cleaned in the Wash Room. The Wash Room must be separated from the work area by a polyethylene sheeting flap door. Waste water must be filtered and filters must be changed as required in accordance with manufacturers recommendations for the shower unit and the Wash Room. Filters must be disposed of as LBP contaminated waste. The Holding Room must be used as a drop location for bagged LBP contaminated waste passed from the Wash Room. This room must be constructed so that bagged materials cannot be passed from the Wash Room through the Holding Room.

j. Maintenance of Decontamination Units. Barriers and polyethylene sheeting must be effectively sealed and taped. Containment barriers must be visually inspected at the beginning of each work period.

Damaged barriers and defects must be immediately repaired upon discovery. Smoke methods must be used to test effectiveness of barriers when directed by the Contracting Officer.

k. LBP Control Area Exiting Procedures. Personnel exiting a LBP control area must perform the following procedures and must not leave the work place wearing any clothing or equipment worn during the work day:

(1) Vacuum all protective clothing before removing.

(2) Remove protective clothing in the decontamination room and place this clothing in an approved impermeable disposal bag.

(3) Wash or shower.

(4) Change to clean clothes prior to leaving the physical boundary designated around the lead-contaminated work site.

l. Building Ventilation Systems. Containment systems must not vent near any building ventilation system intakes. Any building ventilating system or any other system bringing air into or out of the LBP control work area must be shut down and isolated. This can be done by using a lockable switch, disconnecting wires or removing of circuit breakers.

Isolation can be achieved using airtight seals, or other positive means that will prevent spread of contamination through the system and accidental premature restarting of the equipment. Airtight seals must consist of rigid covers for supply and exhaust grills and two layers of polyethylene. Individual seals must be applied to ventilation openings (supply and exhaust), lighting fixtures, clocks, windows, doorways, elevator doors, stairs, ramps, speakers, and other openings into the

SECTION 02 83 20.00 25 Page 17 work area. Seals must be maintained until project decontamination is completed. After decontamination work has been completed and final air sample testing proves that the area is decontaminated, seals must be removed and the ventilating systems may be operated again.

3.2 LBP ABATEMENT AND REMOVAL METHODS

3.2.1 General

LBP abatement and removal methods used in this contract primarily involve removing LBP coated equipment for disposal. LBP removal will be done only as necessary in way of areas to be cut to facilitate removal of the elevator.

Cutting of structural steel must be done after paint is removed to minimize airborne lead. Large scale LBP abatement and removal is not the intent nor required under this contract. The LBP abatement and removal methods would likely include chemical stripping. Minimal grinding of LBP coated surfaces is anticipated. To the extent possible, LBP coated surfaces of equipment removed for disposal must not be abated or removed, but properly packaged, according to regulations, and disposed at a regulated LBP disposal facility.

3.2.2 Chemical Stripping

LBP can be removed from parts by using approved chemical strippers.

Chemical strippers containing methylene chloride are prohibited. Stripping must be done according to manufacturer's recommendations. Substrates must be thoroughly washed and neutralized. Waste generated by the stripping process must be handled in accordance with the Hazardous Waste Management Plan. Adjacent structures and waterways must be protected to prevent contamination.

3.2.3 Drilling

Drilling into metal surfaces containing LBP must be performed using the same safety and environmental protective measures as chemical stripping methods.

3.3 MONITORING

3.3.1 General

During the entire LBP abatement, removal and disposal operations, a Competent Person must be on-site directing the monitoring/sampling and inspecting of the work to ensure that the health and safety requirements of this contract are satisfied.

3.3.2 Personal Air Monitoring

Airborne concentrations of lead must be collected and analyzed in accordance with CFR Part 1926 Section .62. Results must be reported in micrograms per cubic meter of air. The Competent Person must use personal air monitoring results to determine the effectiveness of engineering controls, the adequacy of personal protective equipment and to determine if proper work practices are being employed. The Government must be notified if any personal air monitoring result equals or exceeds 30 micrograms per cubic meter of air. The permissible exposure limit is 50 mg/m3 over an 8-hour period. The Contractor must take steps to reduce the concentration of lead in the air.

SECTION 02 83 20.00 25 Page 18

3.3.3 Wipe Sampling

a. General. Wipe sampling for lead dust concentrations must be conducted as follows during:

(1) LBP removal to monitor activities and ensure containment integrity.

(2) Post abatement to determine if specified clearance criteria has been met.

b. Pre-abatement. Pre-abatement wipe samples must be collected outside the LBP control area in accordance with paragraph 3.1.6c. Samples outside the LBP control work area must be collected at critical barriers, in the clean room of the decontamination unit (if used) and in traffic control areas such as personal and equipment entrances.

c. Abatement. The Industrial Hygienist (IH) must collect wipe samples on a daily basis or as specified in the LBP Management Plan. Wipe samples must be collected outside of the LBP control area in accordance with paragraph 3.1.6.d. Samples must be collected outside the LBP control work area at critical barriers, in the clean room of the decontamination unit (if used) and in traffic control areas such as personal and equipment entrances. Additional samples must be collected during disassembly to monitor the effectiveness of housekeeping measures. The frequency of these additional samples must be as directed by the IH or at the direction of the Government.

d. Wipe Sampling Results.

(1) The contractor must have the results of the wipe sampling within 48 hours after the completion of the sampling. Results must be reported in micrograms per square foot.

(2) LBP removal work being conducted within a LBP control area must be stopped and the Government immediately notified if measured dust wipe concentration levels collected outside the containment area, during removal, exceed the pre-abatement levels. At the direction of the government the outside areas must be cleaned.

The cleaning must bin in accordance with paragraph 3.5. This cleanup must be completed prior to clearance to return to work.

Additional wipe samples must be collected and analyzed to assure the areas are clean. Cleaning and re-sampling must continue until levels, as stated above, are achieved. The contractor must correct containment and/or work practices to mitigate the problem. Removal work must resume when approval is given.

e. Post Abatement. Post abatement samples must be collected in accordance with the paragraph, 3.5.3.

3.3.4 Area Air Monitoring

a. General. If the work area is small, personal air monitoring, described under paragraph 3.3.2, will essentially be the same as area monitoring, and may be deleted. Airborne concentrations of lead must be collected and analyzed in accordance with 29 CFR 1926.62. Results must be reported in micrograms per cubic meter of air.

b. Pre-abatement. Abatement samples must be collected in the following

SECTION 02 83 20.00 25 Page 19

The Dalles Dam Bay locations outside the work area: one upwind of the abatement and two downwind of the removal activities.

c. Abatement. The IH must collect area air samples on a daily basis, or as specified in the LBP Management Plan during abatement and removal activities. The samples must be collected in the same location as the pre-abatement samples.

d. Results. The results of the area air monitoring must be obtained within 48 hours after completion of the sampling. Results must be reported in micrograms per cubic meter of air.

e. Excessive Levels. Outdoor LBP abatement and removal work must cease and the Government notified if measured airborne lead concentrations, collected during abatement, exceed the pre-abatement airborne concentration levels. The Contractor must be required to clean and re-sample the affected area, if directed, at no additional cost to the Government. The work practices and/or engineering controls must be corrected and abatement and removal work must resume at the direction of the Government.

3.3.5 Waste Sampling and Testing

Sampling and testing of all waste must be in accordance with 40 CFR 261.

Sampling Results will be recorded daily. A daily log of the personal and environmental air sampling test results reviewed by the Competent Person and submitted, in written form, no more than 48 hours after completion of the sampling cycle. The log must list each sample result, sampling time and date, sample type, identification of personnel monitored, flow rate and duration, air volume sampled, yield of lead, cassette size, analytical method used, analyst's name and company, and interpretation results.

Results must be reported in micrograms of lead per cubic meter of air. In addition, the daily log must include the results of dust wipe samples, and TCLP sampling including each phase of pre-abatement, during abatement and final clearance. Documentation of the results that exceed specified limits (personal air samples that exceed 30 micrograms per cubic meter), or, as required by Federal, state or local requirements, must be highlighted in the log in such a manner to make them easily distinguishable from monitoring results that do not exceed specified or regulatory limits.

3.4 ADJACENT AREAS

Damage to adjacent areas must be repaired and repairs will be approved by the Government.

3.5 CLEANUP AND DISPOSAL

3.5.1 Cleanup

a. Daily. Surfaces in the LBP control areas must be maintained free of accumulations of paint chips, drill cuttings and dust. Spread of dust and debris must be restricted; waste must not be distributed over the work area. Dry sweep or compressed air must not be used for cleanup.

At the end of each shift, the area must be cleaned of visible lead paint contamination by vacuuming with a HEPA filtered vacuum cleaner.

LBP removal work must cease during cleanup.

b. Prior to Clearance. Upon completion of the lead paint removal in a given work area, cleanup must be performed by the Contractor. This

SECTION 02 83 20.00 25 Page 20 cleanup includes removal of any contaminated material, equipment or debris including polyethylene sheeting from the work area, except for critical barriers.
