SECTION 02 82 16.00 20
ENGINEERING CONTROL OF ASBESTOS CONTAINING MATERIALS
04/06
NOTE: This guide specification covers the requirements for safety procedures
and requirements for the demolition, removal, encapsulation, and disposal of
asbestos containing materials (ACM).
Edit this guide specification for project specific requirements by adding, deleting,
or revising text. For bracketed items, choose applicable items(s) or insert
appropriate information.
Remove information and requirements not required in respective project, whether
or not brackets are present.
Comments and suggestions on this guide specification are welcome and should
be directed to the technical proponent of the specification. A listing of technical
proponents, including their organization designation and telephone number, is
on the Internet.
Recommended changes to a UFGS should be submitted as a Criteria Change Request
(CCR).
NOTE: Federal regulations require EPA model accreditation plan training to
edit this document. Furthermore, asbestos abatement designers must be accredited
and licensed to design asbestos work in the location of the construction.
Nonfriable asbestos containing materials do not always require special handling.
However, during demolition and removal of this material dust and airborne asbestos
fibers will sometimes be released. If the project contains nonfriable asbestos
which may release fibers when demolished and removed, the nonfriable asbestos
shall be removed in the same way as friable asbestos.
OSHA regulations address worker protection, NESHAPS (EPA) regulations address
disposal requirements, and they have different definitions as to what constitutes
ACM in wallboard/joint compound systems. Therefore, where wallboard/joint compound
are suspected to contain ACM, analyze both discrete samples (separate samples
from wallboard and joint compound) to address worker protection and composite
samples (wallboard system as a whole) to address disposal requirements. It
is not unusual for the wallboard itself and the wallboard system (taken as a
whole) to contain less than 1 percent asbestos, but the discrete joint compound
samples to contain greater than 1 per cent asbestos. Problems can arise if
these materials are not properly categorized in the design. Also, if the material
is applied as an “add on” or “skim coat”, NESHAPS considers the layers separate
and composite sampling is not appropriate.
Asbestos operations do not always indicate negative pressure enclosure type
asbestos control with all of its attendant requirements. The location of the
area, type of material, and initial as well as other exposure assessments for
abatement workers and the environment must be reviewed and a judgment made by
the designer as to the precise asbestos control techniques described herein
that may be safely and legally used.
It is the policy of the Navy to eliminate the use of materials containing asbestos
wherever possible. Therefore, the designer shall not use asbestos containing
materials wherever a substitute, suitable to the Navy, exists.
The limits and conditions of asbestos hazard abatement efforts must be indicated
on the drawings or in the specification in sufficient detail for the Contractor
to submit an accurate bid. Portions of the building where asbestos work will
take place must be unoccupied during the removal operation. It is highly recommended
that the entire building be unoccupied during asbestos hazard abatement operations.
If portions of the building where asbestos hazard abatement is not taking place
must remain occupied, additional requirements must be added for providing temporary
heating/cooling and other utilities to the occupied portions of the building.
The building heating/cooling system for example cannot be operated in the asbestos
control area and due to wet removal procedures, electrical service to the asbestos
control area may need to be shut off and resupplied through a ground fault circuit
interrupter. In addition, the rooms with openings into the room undergoing
asbestos abatement must be empty with critical barriers installed to provide
a buffer zone.
NOTE: The following information shall be shown on the project drawings:
1. The project drawings shall clearly show location, extent, condition and
form of asbestos materials to be controlled or in contact with other non-ACM
removals or new work.

Procedures" per standard practice of the activity preparing the contract.
NOTE: Include reference to 40 CFR 763 when asbestos work occurs in a public
or private school Grades K thru 12.
NOTE: Nonfriable ACM may not require special handling. However, during demolition
and removal of this material dust and airborne asbestos fibers will sometimes
be released. If the project contains nonfriable asbestos which may release
fibers when demolished and removed, the nonfriable asbestos shall be removed
in the same way as friable asbestos. Include "Under normal.... specified herein.",
if material traditionally defined as non-friable asbestos materials are to be
removed.
NOTE: The appropriate engineering control technique must comply with the requirements
outlined in 29 CFR 1926.1101 which is selected based on existing conditions,
but must be that technique that provides the best control during abatement at
most reasonable cost.
The work covered by this section includes the handling and control of asbestos containing materials and describes
some of the resultant procedures and equipment required to protect workers, the environment and occupants of
the building or area, or both, from contact with airborne asbestos fibers. The work also includes the disposal
of any asbestos containing materials generated by the work. More specific operational procedures shall be outlined
in the Asbestos Hazard Abatement Plan called for elsewhere in this specification. The asbestos work includes
the [demolition and removal] [encapsulation] of [_____] located [_____] [which is governed by 40 CFR 763]. [Under
normal conditions non-friable or chemically bound materials containing asbestos would not be considered hazardous;
however, this material may release airborne asbestos fibers during demolition and removal and therefore must
be handled in accordance with the removal and disposal procedures as specified herein.] Provide [negative pressure
enclosure] [_____] techniques as outlined in this specification. The Navy will evacuate the [building] [work
area] during the asbestos abatement work. All asbestos removal work shall be supervised by a competent person
as specified herein.

contractor's license issued by the [State of _____][Commonwealth of Virginia].
1.5.5 Air Sampling Results
NOTE: Normal practice is to have the Contractor hire one independent Private
Qualified Person (the PQP) to perform all required functions. However, some
applicable laws forbid this approach and will dictate when the PQP, the NC or
both will be required to perform the function involved. However, the Contractor
shall always hire a PQP.

of the sample pump. Notify the Contracting Officer immediately of any airborne levels of asbestos fibers in
excess of the acceptable limits. Submit sampling results to the Contracting Officer and the affected Contractor
employees where required by law within 3 working days, signed by the testing laboratory employee performing air
sampling, the employee that analyzed the sample, and the [PQP] [and] [NC]. Notify the Contractor and the Contracting
Officer immediately of any variance in the pressure differential which could cause adjacent unsealed areas to
have asbestos fiber concentrations in excess of 0.01 fibers per cubic centimeter or background whichever is higher.
In no circumstance shall levels exceed 0.1 fibers per cubic centimeter.
1.5.6 Pressure Differential Recordings for Local Exhaust System
NOTE: When an negative pressure enclosure is not required, delete the requirements
for the local exhaust system and pressure differential recording.
NOTE: Normal practice is to have the Contractor hire one independent Private
Qualified Person (the PQP) to perform all required functions. However, some
applicable laws forbid this approach and will dictate when the PQP, the NC or
both will be required to perform the function involved. However, the Contractor
shall always hire a PQP.
Provide a local exhaust system that creates a negative pressure of at least 0.51 mm 0.02 inches of water relative
to the pressure external to the enclosure and operate it continuously, 24 hours a day, until the temporary enclosure
of the asbestos control area is removed. Submit pressure differential recordings for each work day to the [PQP]
[and] [NC] for review and to the Contracting Officer within 24 hours from the end of each work day.
[1.5.7 Protective Clothing Decontamination Quality Control Records
Provide all records that document quality control for the decontamination of reusable outer protective clothing.
][1.5.8 Protective Clothing Decontamination Facility Notification

3.1.4 Local Exhaust System
NOTE: When a negative pressure enclosure is not required, delete the requirements
for the local exhaust system and pressure differential recording.
Provide a local exhaust system in the asbestos control area in accordance with ANSI Z9.2 and 29 CFR 1926.1101
that will provide at least four air changes per hour inside of the negative pressure enclosure. Local exhaust
equipment shall be operated 24 hours per day, until the asbestos control area is removed and shall be leak proof
to the filter and equipped with HEPA filters. Maintain a minimum pressure differential in the control area of
minus 0.51 mm 0.02 inch of water column relative to adjacent, unsealed areas. Provide continuous 24-hour per
day monitoring of the pressure differential with a pressure differential automatic recording instrument. In

3.1.6 Rental Equipment
If rental equipment is to be used, furnish written notification to the rental agency concerning the intended
use of the equipment and the possibility of asbestos contamination of the equipment.
[3.1.7 Glovebags
NOTE: Include this paragraph if glovebag technique is permitted to be used
in the project.
Submit written manufacturers proof that glovebags will not break down under expected temperatures and conditions.
]3.2 WORK PROCEDURE
NOTE: Use wet removal procedures in almost all cases. Wet removal is the preferred
method and the least hazardous. Dry removal as an option can be used to allow
the Contractor to use dry removal where wet removal may damage equipment or
present an extreme hazard. Dry removal as the only method of removal should
only be specified if freezing is likely to occur, safety hazards preclude the
use of water, or severe water damage to equipment, etc., would occur during
wet removal. If dry removal alone is allowed, carefully edit the specification
to remove all reference to amended water and wetting down procedures and to
include a requirement for a written variance submitted by the Contractor along
with the written approval of any regulatory authority having jurisdiction.
NOTE: Negative pressure enclosure and glovebag techniques pertain to the two
most general but yet essentially different asbestos control techniques used
for asbestos removal. Encapsulation work practice techniques are listed here,
also. The use of unlisted removal work practice techniques will be acceptable
if they are proven at least as safe as the listed practices. The appropriate
technique depends on existing conditions, but must be that technique that provides
the best control during abatement at most reasonable cost.
Perform asbestos related work in accordance with 29 CFR 1926.1101, 40 CFR 61-SUBPART M, and as specified herein.
Use [[wet] [or] [if given prior EPA approval, dry] removal procedures] [appropriate encapsulation procedures
as listed in the asbestos hazard abatement plan] and [negative pressure enclosure] [_____] techniques. Personnel
shall wear and utilize protective clothing and equipment as specified herein. Eating, smoking, drinking, chewing
gum, tobacco, or applying cosmetics shall not be permitted in the asbestos work or control areas. Personnel
of other trades not engaged in the [encapsulation] [removal and demolition] of asbestos containing material shall
not be exposed at any time to airborne concentrations of asbestos unless all the personnel protection and training
provisions of this specification are complied with by the trade personnel. [Seal all roof top penetrations,
except plumbing vents, prior to asbestos roofing work.] Shut down the building heating, ventilating, and air
conditioning system, cap the openings to the system, [and provide temporary [heating,] [and] [ventilation,] [and]
[air conditioning]] prior to the commencement of asbestos work. [Disconnect electrical service when [encapsulation]
[wet removal] is performed and provide temporary electrical service with verifiable ground fault circuit interrupter
(GFCI) protection prior to the use of any [water] [encapsulant].] If an asbestos fiber release or spill occurs
[outside of the asbestos control area], stop work immediately, correct the condition to the satisfaction of the
Contracting Officer including clearance sampling, prior to resumption of work.
3.2.1 Protection of Existing Work to Remain
NOTE: Normal practice is to have the Contractor hire one independent Private
Qualified Person (the PQP) to perform all required functions. However, some
applicable laws forbid this approach and will dictate when the PQP, the NC or
both will be required to perform the function involved. However, the Contractor
shall always hire a PQP.
Perform work without damage or contamination of adjacent work. Where such work is damaged or contaminated as
verified by the Contracting Officer using visual inspection or sample analysis, it shall be restored to its original
condition or decontaminated by the Contractor at no expense to the Government as deemed appropriate by the Contracting
Officer. This includes inadvertent spill of dirt, dust, or debris in which it is reasonable to conclude that
asbestos may exist. When these spills occur, stop work immediately. Then clean up the spill. When satisfactory
visual inspection and air sampling results are obtained from the [PQP] [NC] work may proceed at the discretion
of the Contracting Officer.
3.2.2 Furnishings
NOTE: Choose one of the following options. In most projects, the Government
will remove furniture and equipment before the Contractor begins work. In this
case the first paragraph should be used. The third paragraph should only be
used when existing furnishings have been contaminated with asbestos fibers and
the Contractor will be required to clean these items. When the third paragraph
is used, identify the furnishings and indicate the quantity of each.
NOTE: The designer must decide if porous, non-solid surfaced items can be cleaned
or must be disposed of as contaminated waste. If cleaning is chosen, specify
methods.
[Furniture [,(_____)] and equipment will be removed from the area of work by the Government before asbestos work
begins.]
[Furniture [,(_____)] and equipment will remain in the building. Cover and seal furnishings with 0.15 mm 6-mil
plastic sheet or remove from the work area and store in a location on site approved by the Contracting Officer.]
[Furnishings listed below and located in the work area are considered to be contaminated with asbestos fibers.
Transfer these items to an area on site approved by the Contracting Officer, decontaminate (wet methods where
possible), and then store until the room from which they came is declared clean and safe for entry. [Carpets,
draperies, and other items with porous, non-solid surfaces can not be suitably cleaned and shall be properly
disposed of as contaminated waste.] At the conclusion of the asbestos removal work and cleanup operations, transfer
all objects so removed and cleaned back to the area from which they came and re-install them. Base bids on decontaminating:
a. [_____] Desks
b. [_____] Filing cabinets
c. [_____] Linear meters feet of shelving
d. [_____] Cubic meters feet of books, papers, files, etc.
e. [_____]].
3.2.3 Precleaning
Wet wipe and HEPA vacuum all surfaces potentially contaminated with asbestos prior to establishment of an enclosure.
3.2.4 Asbestos Control Area Requirements
NOTE: When negative pressure enclosure is infeasible, use paragraph entitled
"Glovebag" and delete paragraph entitled "Negative Pressure Enclosure." If
the project has both areas which can be enclosed and areas which cannot be enclosed,
retain the appropriate paragraphs and identify the areas which must be enclosed
and the areas which cannot be enclosed.
3.2.4.1 Negative Pressure Enclosure
Block and seal openings in areas where the release of airborne asbestos fibers can be expected. Establish an
asbestos negative pressure enclosure with the use of curtains, portable partitions, or other enclosures in order
to prevent the escape of asbestos fibers from the contaminated asbestos work area. Negative pressure enclosure
development shall include protective covering of uncontaminated walls, and ceilings with a continuous membrane
of two layers of minimum 0.15 mm 6-mil plastic sheet sealed with tape to prevent water or other damage. Provide
two layers of 0.15 mm 6-mil plastic sheet over floors and extend a minimum of 300 mm 12 inches up walls. Seal
all joints with tape. Provide local exhaust system in the asbestos control area. Openings will be allowed in
enclosures of asbestos control areas for personnel and equipment entry and exit, the supply and exhaust of air
for the local exhaust system and the removal of properly containerized asbestos containing materials. Replace
local exhaust system filters as required to maintain the efficiency of the system.
[3.2.4.2 Glovebag
NOTE: Specify the asbestos material to be removed in the first blank and identify
the location of the area which cannot be enclosed in the second blank.
The construction of a negative pressure enclosure is infeasible for the [removal] [encapsulation] of [_____]
located [_____]. Use alternate techniques as indicated in 29 CFR 1926.1101. Establish designated limits for
the asbestos regulated area with the use of rope or other continuous barriers, and maintain all other requirements
for asbestos control areas. The PQP shall conduct personal samples of each worker engaged in asbestos handling
(removal, disposal, transport and other associated work) throughout the duration of the project. If the quantity
of airborne asbestos fibers monitored at the breathing zone of the workers at any time exceeds background or
0.01 fibers per cubic centimeter whichever is greater, stop work, evacuate personnel in adjacent areas or provide
personnel with approved protective equipment at the discretion of the Contracting Officer. This sampling may
be duplicated by the Government at the discretion of the Contracting Officer. If the air sampling results obtained
by the Government differ from those obtained by the Contractor, the Government will determine which results predominate.
If adjacent areas are contaminated as determined by the Contracting Officer, clean the contaminated areas, monitor,
and visually inspect the area as specified herein.
][3.2.5 Removal Procedures
NOTE: Choose "Removal Procedures" or "Encapsulation Procedures" as appropriate
for the project.
Wet asbestos material with a fine spray of [amended water] [a specific wetting agent such as light oil] during
removal, cutting, or other handling so as to reduce the emission of airborne fibers. Remove material and immediately
place in 0.15 mm 6 mil plastic disposal bags. Remove asbestos containing material in a gradual manner, with
continuous application of the amended water or wetting agent in such a manner that no asbestos material is disturbed
prior to being adequately wetted. Where unusual circumstances prohibit the use of 0.15 mm 6 mil plastic bags,
submit an alternate proposal for containment of asbestos fibers to the Contracting Officer for approval. For
example, in the case where both piping and insulation are to be removed, the Contractor may elect to wet the
insulation, wrap the pipes and insulation in plastic and remove the pipe by sections. Asbestos containing material
shall be containerized while wet. At no time shall asbestos material be allowed to accumulate or become dry.
Lower and otherwise handle asbestos containing material as indicated in 40 CFR 61-SUBPART M.
3.2.5.1 Sealing Contaminated Items Designated for Disposal
NOTE: Use this paragraph only when asbestos contaminated items are also designated
for removal and disposal.
Remove contaminated architectural, mechanical, and electrical appurtenances such as venetian blinds, full-height
partitions, carpeting, duct work, pipes and fittings, radiators, light fixtures, conduit, panels, and other contaminated
items designated for removal by completely coating the items with an asbestos lock-down encapsulant at the demolition
site before removing the items from the asbestos control area. These items need not be vacuumed. The asbestos
lock-down encapsulant shall be tinted a contrasting color. It shall be spray-applied by airless method. Thoroughness
of sealing operation shall be visually gauged by the extent of colored coating on exposed surfaces. Lock-down
encapsulants shall comply with the performance requirements specified herein.
3.2.5.2 Exposed Pipe Insulation Edges
Contain edges of asbestos insulation to remain that are exposed by a removal operation. Wet and cut the rough
ends true and square with sharp tools and then encapsulate the edges with a 6 mm 1/4 inch thick layer of non-asbestos
containing insulating cement troweled to a smooth hard finish. When cement is dry, lag the end with a layer
of non-asbestos lagging cloth, overlapping the existing ends by at least 100 mm 4 inches. When insulating cement
and cloth is an impractical method of sealing a raw edge of asbestos, take appropriate steps to seal the raw
edges as approved by the Contracting Officer.
][3.2.6 Encapsulation Procedures
NOTE: Choose "Removal Procedures" or "Encapsulation Procedures" as appropriate
for the project.
3.2.6.1 Preparation of Test Patches
NOTE: Prior to preparing plans and specifications for an encapsulation project,
the designer will have to ascertain that encapsulation is feasible at all.
The foremost design criteria is the soundness of the existing asbestos containing
matrix, i.e. the bond of the matrix to the substrate and the shear strength
of the matrix itself. The designer should test the existing matrix in accordance
with the ASTM E 1494, using the Field Testing Provisions for the Adhesion Test.
NOTE: Exercise discretion on the number and location of Contractor applied
test patches. However, a minimum of three test patches should always be specified.
Test locations, in areas of the matrix, that have a different appearance or
raise doubts about their homogeneity. Specify number of test patches in first
bracket and location in second bracket. Also show location on drawings.
Install [three] [_____] test patches of encapsulant in [_____], as indicated. Use airless spray at the lowest
pressure and as recommended by the encapsulant manufacturer. Follow exactly the manufacturer's instructions
for thinning recommendations, application procedures and rates. Curing time shall be not less than five days
or that recommended by the manufacturer, whichever is more. A test patch shall be 0.8 square meter 9 square
feet in size.
3.2.6.2 Field Testing
Field test the encapsulation test patches in accordance with ASTM E 1494, paragraph "Required Field Test," in
the presence of the Contracting Officer. Keep a written record of the testing procedures and test results.
Upon successful testing of the encapsulant, submit a signed statement to the Contracting Officer certifying that
the encapsulant is suitable for installation on the particular asbestos containing material.
3.2.6.3 Large-Scale Application
Apply encapsulant using the same equipment and procedures as employed for the test patches. Keep the encapsulant
material stirred to prevent settling. Keep a clean work area. Change pre-filters in the ventilation equipment
as soon as they appear clogged by encapsulant aerosol or pressure differential drops below 0.02 Hg.
]3.2.7 Air Sampling
NOTE: Air sampling regimen is very dependent on removal method and applicable
laws, edit accordingly.
NOTE: Normal practice is to have the Contractor hire one independent Private
Qualified Person (the PQP) to perform all required functions. However, some
applicable laws forbid this approach and will dictate when the PQP, the NC or
both will be required to perform the function involved. However, the Contractor
shall always hire a PQP.
Sampling of airborne concentrations of asbestos fibers shall be performed in accordance with 29 CFR 1926.1101
and as specified herein. Sampling performed in accordance with 29 CFR 1926.1101 shall be performed by the PQP.
[Sampling performed for environmental and quality control reasons shall be performed by the [PQP] [NC].] Unless
otherwise specified, use NIOSH Method 7400 for sampling and analysis. Monitoring may be duplicated by the Government
at the discretion of the Contracting Officer. If the air sampling results obtained by the Government differ
from those results obtained by the Contractor, the Government will determine which results predominate.
3.2.7.1 Sampling Prior to Asbestos Work
Provide area air sampling and establish the baseline one day prior to the masking and sealing operations for
each [demolition] [removal] [encapsulation] site. Establish the background by performing area sampling in similar
but uncontaminated sites in the building.
3.2.7.2 Sampling During Asbestos Work
NOTE: Choose one of the following options. Normal practice is to have the
Contractor hire one independent Private Qualified Person (the PQP) to perform
all required functions. However, some applicable laws forbid this approach
and will dictate when the PQP, the NC or both will be required to perform the
function involved. However, the Contractor shall always hire a PQP.
NOTE: When an "enclosed" asbestos control area is not required, retain the
appropriate portion in brackets.
[The PQP shall provide personal and area sampling as indicated in 29 CFR 1926.1101 and governing environmental
regulations. In addition, provided the same type of work is being performed, provide area sampling at least
once every work shift close to the work inside the enclosure, outside the clean room entrance to the enclosure,
and at the exhaust opening of the local exhaust system. If sampling outside the enclosure shows airborne levels
have exceeded background or 0.01 fibers per cubic centimeter, whichever is greater, stop all work, correct the
condition(s) causing the increase, and notify the Contracting Officer immediately. [Where alternate methods
are used, perform personal and area air sampling at locations and frequencies that will accurately characterize
the evolving airborne asbestos levels.]]
[The PQP shall provide personal sampling as indicated in 29 CFR 1926.1101. At the same time the NC will provide
area sampling close to the work inside the enclosure, outside the clean room entrance to the enclosure, and at
the exhaust opening of the local exhaust system. In addition, provided the same type of work is being performed,
the NC will provide area sampling once every work shift close to the work inside the enclosure, outside the clean
room entrance to the enclosure, and at the exhaust opening of the local exhaust system. If sampling outside
the enclosure shows airborne levels have exceeded background or 0.01 fibers per cubic centimeter, whichever is
greater, stop all work, correct the condition(s) causing the increase, and notify the Contracting Officer immediately.
[Where alternate methods are used, perform personal and area air sampling at locations and frequencies that will
accurately characterize the evolving airborne asbestos levels.]]
3.2.7.3 Sampling After Final Clean-Up (Clearance Sampling)
NOTE: The designer shall research the State, regional and local laws, regulations,
statutes, etc., to determine whether "aggressive" air sampling is required.
However, always use aggressive air sampling techniques after encapsulation type
abatement efforts.
NOTE: Normal practice is to have the Contractor hire one independent Private
Qualified Person (the PQP) to perform all required functions. However, some
applicable laws forbid this approach and will dictate when the PQP, the NC or
both will be required to perform the function involved. However, the Contractor
shall always hire a PQP.
NOTE: The designer shall research the State, regional and local laws, regulations,
statutes, etc., to determine whether TEM analysis is required and the number
of samples required.
Provide area sampling of asbestos fibers [using aggressive air sampling techniques as defined in the EPA 560/5-85-024
] and establish an airborne asbestos concentration of less than 0.01 fibers per cubic centimeter after final
clean-up but before removal of the enclosure or the asbestos work control area. After final cleanup and the
asbestos control area is dry but prior to clearance sampling, the [PQP] [and] [NC] shall perform a visual inspection
in accordance with ASTM E 1368 to ensure that the asbestos control and work area is free of any accumulations
of dirt, dust, or debris. [Prepare a written report signed and dated by the PQP documenting that the asbestos
control area is free of dust, dirt, and debris and all waste has been removed.] [Perform at least [_____] samples.]
[Use transmission electron microscopy (TEM) to analyze clearance samples and report the results in accordance
with current NIOSH criteria.] The asbestos fiber counts from these samples shall be less than 0.01 fibers per
cubic centimeter or be not greater than the background, whichever is greater. Should any of the final samples
indicate a higher value, the Contractor shall take appropriate actions to re-clean the area and shall repeat
the sampling and [TEM] analysis at the Contractor's expense.
3.2.8 Lock-Down
Prior to removal of plastic barriers and after pre-clearance clean up of gross contamination, the [PQP] [NC]
shall conduct a visual inspection of all areas affected by the [removal] [encapsulation] in accordance with ASTM E 1368
. Inspect for any visible fibers [, and to ensure that encapsulants were applied evenly and appropriately].
[A post removal (lock-down) encapsulant shall then be spray applied to ceiling, walls, floors and other areas
exposed in the removal area. The exposed area shall include but not be limited to plastic barriers, furnishings
and articles to be discarded as well as dirty change room, air locks for bag removal and decontamination chambers.]
3.2.9 Site Inspection
While performing asbestos engineering control work, the Contractor shall be subject to on-site inspection by
the Contracting Officer who may be assisted by or represented by safety or industrial hygiene personnel. If
the work is found to be in violation of this specification, the Contracting Officer or his representative will
issue a stop work order to be in effect immediately and until the violation is resolved. All related costs including
standby time required to resolve the violation shall be at the Contractor's expense.
3.3 CLEAN-UP AND DISPOSAL
3.3.1 Housekeeping
Essential parts of asbestos dust control are housekeeping and clean-up procedures. Maintain surfaces of the
asbestos control area free of accumulations of asbestos fibers. Give meticulous attention to restricting the
spread of dust and debris; keep waste from being distributed over the general area. Use HEPA filtered vacuum
cleaners. DO NOT BLOW DOWN THE SPACE WITH COMPRESSED AIR. When asbestos removal is complete, all asbestos waste
is removed from the work-site, and final clean-up is completed, the Contracting Officer will attest that the
area is safe before the signs can be removed. After final clean-up and acceptable airborne concentrations are
attained but before the HEPA unit is turned off and the enclosure removed, remove all pre-filters on the building
HVAC system and provide new pre-filters. Dispose of filters as asbestos contaminated materials. Reestablish
HVAC mechanical, and electrical systems in proper working order. The Contracting Officer will visually inspect
all surfaces within the enclosure for residual material or accumulated dust or debris. The Contractor shall
re-clean all areas showing dust or residual materials. If re-cleaning is required, air sample and establish
an acceptable asbestos airborne concentration after re-cleaning. The Contracting Officer must agree that the
area is safe in writing before unrestricted entry will be permitted. The Government shall have the option to
perform monitoring to determine if the areas are safe before entry is permitted.
3.3.2 Title to Materials
All waste materials, except as specified otherwise, shall become the property of the Contractor and shall be
disposed of as specified in applicable local, State, and Federal regulations and herein.
3.3.3 Disposal of Asbestos
NOTE: Disposal procedures and sites for asbestos materials vary considerably
with each location. Contact local station Public Works and the NAVFAC Engineering
Field Division Hazardous Waste Manager or Industrial Hygienist for local procedures.
3.3.3.1 Procedure for Disposal
Collect asbestos waste, asbestos contaminated water, scrap, debris, bags, containers, equipment, and asbestos
contaminated clothing which may produce airborne concentrations of asbestos fibers and place in sealed fiber-proof,
waterproof, non-returnable containers (e.g. double plastic bags 0.15 mm 6 mils thick, cartons, drums or cans).
Wastes within the containers must be adequately wet in accordance with 40 CFR 61-SUBPART M. Affix a warning
and Department of Transportation (DOT) label to each container including the bags or use at least 0.15 mm 6 mils
thick bags with the approved warnings and DOT labeling preprinted on the bag. The name of the waste generator
and the location at which the waste was generated shall be clearly indicated on the outside of each container.
Prevent contamination of the transport vehicle (especially if the transport vehicle is a rented truck likely
to be used in the future for non-asbestos purposes). These precautions include lining the vehicle cargo area
with plastic sheeting (similar to work area enclosure) and thorough cleaning of the cargo area after transport
and unloading of asbestos debris is complete. Dispose of waste asbestos material at an Environmental Protection
Agency (EPA) or State-approved asbestos landfill off Government property. For temporary storage, store sealed
impermeable bags in asbestos waste drums or skids. An area for interim storage of asbestos waste-containing
drums or skids will be assigned by the Contracting Officer or his authorized representative. Procedure for hauling
and disposal shall comply with 40 CFR 61-SUBPART M, State, regional, and local standards. Sealed plastic bags
may be dumped from drums into the burial site unless the bags have been broken or damaged. Damaged bags shall
remain in the drum and the entire contaminated drum shall be buried. Uncontaminated drums may be recycled.
Workers unloading the sealed drums shall wear appropriate respirators and personal protective equipment when
handling asbestos materials at the disposal site.
3.3.3.2 Asbestos Disposal Quantity Report
NOTE: Normal practice is to have the Contractor hire one independent Private
Qualified Person (the PQP) to perform all required functions. However, some
applicable laws forbid this approach and will dictate when the PQP, the NC or
both will be required to perform the function involved. However, the Contractor
shall always hire a PQP.
[Direct the PQP to record and report, to the Contracting Officer, the amount of asbestos containing material
removed and released for disposal. Deliver the report for the previous day at the beginning of each day shift
with amounts of material removed during the previous day reported in linear meters or square meters linear feet
or square feet as described initially in this specification and in cubic meters feet for the amount of asbestos
containing material released for disposal.]
[Allow the NC to inspect, record and report the amount of asbestos containing material removed and released for
disposal on a daily basis.]
