ASBESTOS MANAGEMENT Program

I. Policy

Lawrence Berkeley National Laboratory (LBL) has adopted an Asbestos
Management Program for asbestos. The policy is to immediately remove or
repair all asbestos containing materials that pose a significant health
hazard due to location or condition. Asbestos that is in good condition
will be maintained in a condition that will not produce a significant
risk to LBL personnel. Asbestos containing material will be removed,
repaired and/or protected prior to planned renovations, demolitions, or
modifications that may result in its disturbance. All removal and
repairs shall be conducted in a safe manner that is consistent with
applicable regulations, DOE requirements, and recognized good practice.

II\. Purpose

The purpose of this document is to outline how the management of
asbestos-containing materials is to be performed at Lawrence Berkeley
National Laboratory.

Asbestos is a generic term referring to fibrous mineral silicates that
were used extensively from about 1900 until very recently in the
manufacture of construction and industrial products. Some products are
still manufactured with a significant asbestos content. Section VI lists
various products that have been manufactured with asbestos. This list is
not exhaustive, other products not listed may also contain asbestos.

Asbestos-containing materials can be divided into two general
categories; friable and non-friable. Friable ACM products are those that
can be readily crumbled or powdered by hand pressure, and are of more
concern than non-friable ACM because of the greater ease of fiber
release. Examples of friable ACM include pipe insulation, sprayed-on
acoustical insulation, and sprayed on fireproofing. Intact and sealed
friable asbestos materials are considered non-friable and do not pose a
health risk if they are undisturbed and undamaged.

Non-friable ACMs generally possess a strong binder such as cement or
vinyl, which stabilizes the asbestos, reducing the likelihood of
generating airborne asbestos dust. However, specific actions such as
sanding, grinding, cutting or drilling of non-friable asbestos can
result in the release of asbestos fibers. Examples of non-friable
asbestos include intact vinyl asbestos floor tiles, roofing
felts/shingles, and asbestos cement products such as transite panels and
pipes.

EPA Guideline \"Managing Asbestos in Place\" (7/90 #20T-2003)

The interplay of EPA, OSHA, and BAAQMD regulations makes asbestos
compliance somewhat complicated. Therefore, frequent consultation with
an EH&S Industrial Hygienist, the Environmental Protection Group and/or
LBL Environmental Counsel on asbestos-related issues is encouraged.

IV\. Definitions

**Abatement.** Removal, encapsulation, enclosure, repair or demolition
of ACM.

**ACM**. Asbestos Containing Material. Building materials which contain
asbestos in an amount greater than 1.0% by weight, area, or count.

**ACM Waste**. Waste materials which contain friable asbestos in an
amount of 1% or greater by weight, area, or count, and
asbestos-contaminated materials (e.g., protective clothing and
equipment).

**Accredited.** The Analytical laboratory used for asbestos analysis
must participate in a quality assurance program administered by the
American Industrial Hygiene Association (AIHA) or the National Institute
of Occupational Safety and Health (NIOSH).

**Asbestos**. A generic term referring to naturally-occurring fibrous
mineral silicates. The three most common types are chrysotile (white)
asbestos, amosite (brown) asbestos, and crocidolite (blue) asbestos.
**Note:** Non-asbestiform tremolite, anthrophyllite and actinolite are
not regulated as an asbestos containing materials.

**CIH**. Certified Industrial Hygienist. A person who is certified in
the comprehensive practice of industrial hygiene by the American Board
of Industrial Hygiene.

**Class I Asbestos Work**. Activities involving the removal of thermal
system insulation (TSI) and surfacing ACM or PACM in an amount greater
than 1 glovebag.

**Class II Asbestos Work.** The removal of asbestos-containing
wallboard, floor tile, roofing materials, transite, construction mastic,
gaskets, etc. Does not involve the removal of TSI or surfacing
materials.

**Class III Asbestos Work.** Activities involving the repair and
maintenance operations, where ACM (including TSI and surfacing
materials) are likely to be disturbed. The amount removed must fit into
1 glovebag or wastebag less than 60\" in width.

**Class IV Asbestos Work.** Maintenance or custodial activities (e.g.,
floor buffing) during which employees contact ACM or PACM, and
activities to clean up waste and debris containing ACM and PACM.

**Competent Person.** One who meets the requirements in 29 CFR 1926.32
(f), and iscapable of identifying existing asbestos hazards in the
workplace, able to select the appropriate control strategy, and has the
authority to take prompt corrective measures to mitigate them.

**Composite**. Several individual parts combining to form one integral
system. For example, a composite asbestos sample of a sheet rock wall
system with asbestos-containing joint compound would be a sample of the
entire wall material, (i.e., joint compound, tape, and wallboard
combined).

**Containment**. The construction of an impermeable barrier around ACM
to prevent the release of fibers into occupied areas during abatement.
In addition, a containment controls the amount of incoming air so that a
negative pressure in the work area can be maintained.

**Contractor**. An individual or business with which LBL arranges to
perform work involving ACM.

**Cumulative**. A series of small renovations or removals of RACM
performed during

**Renovation**. A calendar year that taken together would add up to a
reportable amount.

**Demolition**. The wrecking or taking out of any load-supporting
structural member of a structure. (Note: This definition is for BAAQMD
purposes)

**Encapsulant**. A liquid material that can be applied to ACM which
controls the possible release of asbestos fibers from the material.
Bridging encapsulants do this by creating a membrane over the surface,
while penetrating encapsulants penetrate into the material and bind the
components together.

**Encapsulation**. Application of a encapsulant to ACM to control the
release of asbestos fibers.

**Excursion Limit**. Exposure to asbestos in excess of 1.0 fiber per
cubic centimeter of air (1 f/cc) as averaged over a sampling period of
thirty minutes.

**Fiber**. A particulate form of asbestos five micrometers or longer
with a length to diameter ratio of at least 3 to 1 as determined by PCM.

**Friable**. A material containing asbestos that can be crumbled,
pulverized or reduced to a powder when dry, under hand pressure, or that
has been crumbled, pulverized, or reduced to a powder.

**HEPA Filter.** A high efficiency particulate air filter capable of
filtering 0.3 micrometer particles with 99.97 percent efficiency. This
filter is the only type of filter suitable for asbestos work, both in
respirators and negative air machines.

**Industrial Hygienist**. Professional qualified by education, training
and experience to anticipate, recognize evaluate and develop controls
for occupational health hazards.

**Negative Exposure Assessment.** Demonstration by exposure monitoring
that employee exposure during an operation is expected to be
consistently below the PEL or excursion limit.

**Negative Pressure Ventilation System**. A portable exhaust system
equipped with HEPA filtration and capable of maintaining a negative
pressure of 0.02 inches (or greater) of water in a contained area.

**Nonfriable ACM (Category I)**. Intact asbestos-containing packings,
gaskets, resilient floor coverings, and asphalt roofing products.

**Nonfriable ACM (Category II).** Asbestos-containing material
(excluding Category I) that when dry and in its present form, cannot be
crumbled, pulverized, or reduced to powder by hand pressure. Includes
asbestos cement products, transite board, pipe, plaster, stucco, paint,
and mastics.

**PACM**. Presumed Asbestos Containing Material. Material that may
contain asbestos (see section VI, page 6 for examples of materials) and
has not been sampled for asbestos content, shall be assumed to contain
asbestos and treated accordingly.

**PCM.** Phase Contrast Microscopy. An analytical method used to count
airborne fibers. Results are given as fibers per cubic centimeter of air
(f/cc). OSHA employee exposure standards are based on this method. This
method counts all fibers greater than 5 microns in length, without
specifically identifying the fiber type (e.g., cotton, fiberglass, nylon
etc., will also be counted).

**PEL.** Permissible Exposure Limit. The eight hour time-weighted
average concentration of allowable airborne asbestos fibers to which an
employee may be exposed. The limit for asbestos is 0.1 fibers per cubic
centimeter (f/cc) of air.

**Personal Exposure Monitoring.** Determination of an employees exposure
from breathing zone (i.e., 2 foot radius surrounding the head) air
samples representative of the 8-hour TWA or 30 minute excursion limit.

**Planned Renovation.** Renovation, or a number of renovations, that can
be predicted to occur within one period of time, not to exceed one year.

**PLM** Polarized Light Microscopy. Analytical method used to determine
type and quantity (i.e., percent) of asbestos present in an bulk sample.

**Regulated Asbestos Containing Material (RACM).**

A. Friable ACM

B. Nonfriable Category I ACM that has, or will become friable, or that
has been subjected to sanding, drilling, grinding, cutting, or abrading.

C. Nonfriable Category II ACM that may become crumbled, pulverized, or
reduced to powder by the forces expected to act upon the material in the
course of demolition or renovation.

**Regulated Asbestos Work Area**. An area in which the exposure to
asbestos fibers can reasonably be expected to exceed the PEL of 0.1
fibers per cubic centimeter of air. No one may enter the regulated area
without training and proper protective equipment. Regulated areas are
restricted by barriers, asbestos warning tape, signs (see appendix C)
etc.

**Renovation**. Altering in any way one or more facility components.
Operations in which load-supporting structural members are wrecked or
taken out are considered demolitions.

**Reportable** Defined by the BAAQMD as every demolition, even if no
RACM is involved, and renovations involving removal of RACM greater than
or equal to 100 linear feet, 100 square feet (ft2), or 35 cubic feet
(ft3).

**Structure (in AHERA).** A microscopic bundle, cluster, fiber, or
matrix which may contain asbestos.

**Structural Member**. Any load-supporting member of a facility, such as
beams and load-supporting walls.

**Surfacing Material**. Material that is sprayed, trowelled or otherwise
applied to surfaces (e.g., fireproofing on structural steel, acoustical
plaster on ceilings)

**Surfactant**. A chemical wetting agent added to water to improve
penetration of the water into a solid material.

**TEM**. Transmission Electron Microscopy. This method counts all fiber
sizes (including those less than 5 microns in length) and positively
identifies the type of fiber. The results are reported in structures/cc.
This method is not recognized by the OSHA asbestos standard but is
specified in the AHERA standard.

**TSI**. Thermal System Insulation. Insulation applied to pipes,
fittings, boilers, ducts, etc., to prevent heat loss or gain.

**TWA**. Time Weighted Average. Average airborne exposure to a substance
as averaged over an 8-hour workday.

**Visible Emissions**. Any release of ACM that is visually detectable
without the aid of instruments.

V . Hazardous Properties of Asbestos

Asbestos is primarily an inhalation hazard. Asbestos-related diseases
caused by the inhalation of fibers typically occur 10 to 45 years after
exposure. Asbestos does not cause any acute (immediate) effects, except
skin warts which are mentioned below.

• Asbestosis - permanent fibrotic scarring of lung tissue, which results
in a reduced ability to breathe, cardiovascular failure, and in severe
cases, death.

• Lung Cancer - occurs more often in people exposed to asbestos than in
non-exposed groups. This effect of asbestos exposure is greatly
magnified by cigarette smoking.

• Mesothelioma - cancer of the lining of the chest and abdominal cavity.
A rare disease that occurs almost exclusively in those exposed to
asbestos.

• Skin warts - single asbestos fibers imbedded in the skin may cause
non-cancerous warts. They heal when the fiber is removed.

Asbestos is a demonstrated human carcinogen. Consistent with LBL policy
employee exposure to airborne asbestos shall be limited to levels that
are \"As Low As Reasonably Achievable\" (ALARA).

7\. Provide the Facilities Department with necessary waste disposal
information prior to abatement projects (see Appendix D), as well as a
copy of the waste manifest after receipt from the disposal site, when
applicable.

VIII\. Guidelines

A. Asbestos Program Manager

The Manager of O&M will be the designated \"Asbestos Program Manager\".
This will entail active involvement with all LBL asbestos control
activities and the review of routine work orders for ACM surveys prior
to demolition, renovation, or other instances involving the possible
disturbance of ACM.

B. Building Surveys / Repairs

1\. Buildings constructed after 1979 do not contain
[friable]{.underline} asbestos, and need not be inspected for these
materials prior to demolition/renovation. However, they may contain
non-friable asbestos-containing products (e.g., floor tiles, roofing
etc.), and will need to be inspected for these materials prior to
renovation/demolition. Note: See appendix B for the construction date of
LBL buildings.

2\. The Facilities Department is responsible for the repair of damaged
or deteriorated (unsealed ends, nicks, loose pieces of insulation,
abraded floor tiles, etc.) friable and non-friable ACM. The chart in
Appendix F will be used to decide what type of repair is necessary and
how soon it needs to be performed. An Industrial Hygienist will be
available for consultation on these decisions.

3\. Pre-renovation / Demolition: Facilities is responsible for surveying
the affected structure or areas for ACM prior to any demolition or
renovation, per 40 CFR 61.145 and BAAQMD 11-2-303.8.

4\. If suspected ACM has not undergone laboratory analysis, it should be
assumed to contain asbestos and treated accordingly.

C. Bulk Sampling

1\. The testing, evaluation and sample collection of materials for
asbestos analysis shall be conducted by an accredited Facilities
inspector (40 CFR Part 763) or by a CIH.

2\. Analysis of these samples shall be performed by persons or
laboratories with proficiency demonstrated by participation in the
National Voluntary Laboratory Accreditation Program (NVLAP).

D. Employee Notification

Air monitoring results from the Field Support Group must be given in
writing to the affected employee\'s supervisors/managers within five
working days of their receipt. The supervisor shall give these results
to the affected employee within five working days.

E. Exposure Monitoring and Jobsite Clearance Levels

1\. The current Federal Occupational Safety and Health Administration
(OSHA) \"Permissible Exposure Limit\" (PEL) is 0.1 fibers per cubic
centimeter (f/cc) of air averaged over an 8-hour day. The excursion
limit for any 30 minute exposure is 1.0 f/cc of air.

2\. All samples taken to satisfy monitoring requirements shall be
personal samples.

3\. Initial monitoring of LBL employees who are or may be reasonably
expected to be exposed to airborne asbestos concentrations exceeding the
PEL or Excursion Limit shall be performed by the Field Support Group.
Monitoring may be discontinued when results show that employee exposures
are consistently below the PEL and Excursion Limit. Initial monitoring
shall be repeated whenever there has been a change in the control
equipment, process, personnel, or work practices that may result in new
or additional exposures.

4\. Periodic monitoring shall be performed every six months or less for
employees who perform tasks that may be reasonably foreseen to exceed
the PEL or Excursion Limit.

5\. Acceptable job-site clearance levels are 70 structures per square
millimeter (st/mm2) by TEM. Clearance sampling is not required for
small-scale short duration projects.

F. Flooring Material Maintenance

1\. Rubber wheels (i.e., not plastic) shall be used on chairs that are
in contact with resilient flooring (e.g., linoleum, floor tiles, sheet
flooring). The purpose of this requirement is to prevent floor abrasion
and the subsequent creation of asbestos-containing dust. The Facilities
Work Request Center at extension 6274 is available for assistance in the
replacement of wheels. The cost of the rubber wheels will be at the
expense of the owner of the chair.

2\. Sanding of the flooring, it\'s backing, or mastic, is prohibited.

3\. Stripping of floors shall be conducted using low abrasion pads at
speeds lower than 300 rpm, and wet methods.

4\. Burnishing or dry buffing may be performed only on flooring that has
sufficient finish so that the pad cannot contact the asbestos-containing
material.

5\. Dust and debris in an area containing visibly deteriorated ACM shall
not be dusted, swept dry, or vacuumed without the use of a HEPA vacuum.

G. Hygiene Facilities

1\. For Class 1 asbestos jobs involving over 25 linear or 10 square feet
of TSI or surfacing material, there shall be a decontamination area
(29CFR 1926.1101 (j)) consisting of an equipment room, shower area, and
clean room, in series and connected to the Regulated Area. Employees
must enter and exit through the decontamination area.

2\. For Class 1 involving less than 25 linear or 10 ft2, and Class 2 or
3 work which is above the PEL or where there is no negative exposure
assessment, a equipment room that is adjacent to the Regulated Area
shall be constructed. The floor area and horizontal work surface shall
be constructed of 6-mil plastic (minimum), and be large enough to
accommodate the cleaning of equipment and surfaces of waste containers.
Work clothing must be HEPA vacuumed before it is removed, employees must
enter or exit through the equipment room.

3\. Class IV work at LBL will not require decontamination facilities.
Employees trained at this level will not work in Regulated areas or be
involved in the cleanup of ACM or PACM.

H. Identification of ACM in Buildings

1\. Prior to remodeling, modifying, demolishing, or otherwise disturbing
any facility component, the job site will be visually inspected by a
qualified Facilities Building Inspector. If ACM is potentially present
and an adequate prior survey of the area has not been conducted, a
complete survey must be performed to identify any ACM that may be
disturbed by the planned work. Any such materials that are identified as
ACM must be removed or protected from disturbance before the work can
proceed. (See 40 CFR 61.145 (c) and BAAQMD 11-2-303. For specific bulk
sampling procedures see Appendix G.)

2\. Materials suspected of being ACM but not sampled will be assumed to
contain asbestos and treated accordingly. This is most appropriate when
the task is very limited in scope (e.g., small spill \< 1 ft2, floor
tiles \< 10 ft2) and the cost and time spent collecting and analyzing
the samples is a significant part of, or exceeds, the cost of performing
work.

I. Labeling and Posting

1\. Identified (by laboratory analysis) friable ACM found to contain 1.0
% asbestos or greater should be labeled as shown in Appendix C, Figure
C-1.

2\. Warning signs shall be posted at the outside perimeter of each
regulated area and its approaches as shown in Appendix C, Figure C-2.

3\. Newly installed pipe insulation should be identified as
\"non-asbestos\". An example of a label is shown in Appendix C, Figure
C-4. Buildings constructed after 1979 are exempt from this
recommendation.

J. Medical Surveillance

Any employee identified as being potentially exposed to airborne
asbestos levels at or above PEL or excursion limit, or required to wear
a negative pressure respirator for asbestos, will be provided a complete
asbestos physical as described in 29 CFR 1926.1101 or 29 CFR 1910.1001
by the Health Services Group.

K. New Products Containing Asbestos

No asbestos-containing product shall be procured, stocked, installed, or
used at LBL without prior review by the Field Support Group.

L. Protective Clothing

1\. Employees who may be exposed to airborne asbestos levels exceeding
the PEL or Excursion Limit shall be provided protective clothing ( e.g.,
disposable coveralls, gloves, shoe coverings, safety glasses etc.) and
work equipment at no cost.

2\. Contaminated clothing used in areas that may exceed the PEL or
excursion limit, shall be removed only in change rooms, transported in
sealed, labeled bags, and disposed of as asbestos-containing waste.

M. Regulatory Agency Notification

The BAAQMD requires a minimum of 10 working days notice prior to any
building demolition. The same notification requirement applies to
building renovations involving RACM removal over certain reportable
quantities. An additional category of notification is for a series of
small activities involving RACM which individually do not trigger
notification, but collectively do. This is called a cumulative
notification and it is given once per year. Yearly, planned,
nonscheduled notifications must be submitted by the Environmental
Protection Group (EPG) twenty working days prior to the beginning of the
new calendar year.

The procedure at LBL to ensure compliance with BAAQMD\'s notification
requirements is as follows:

The Environmental Protection Group (EPG) will be informed of every
demolition, whether or not it involves asbestos, and of every removal of
RACM as soon as the work has been planned. The Appendix A \"Asbestos
Removal/Repair\" form will be completed for [all]{.underline} removal of
RACM or PACM if the amount to be removed is less than 100 linear, 100
square feet (ft2) or 35 cubic feet. If greater than these amounts, the
Appendix D notification will be completed and submitted to the EPG a
minimum of 12 days prior to the start of work. EPG will use the
information submitted on the Appendix D form to prepare and submit a
notice to BAAQMD, if required. The exception to the requirement to use
the Appendix D form is if an outside contractor performs work reportable
to BAAQMD and sends BAAQMD the required notice. In that case, it is
sufficient to send EPG a copy of the BAAQMD notice at the time it is
submitted to the BAAQMD.

Changes to information on the Appendix D form, or to a BAAQMD form
submitted by an outside contractor, will also be provided to EPG
immediately. This may be done by a telephone call, an amended Appendix D
form, or a copy of an amended BAAQMD notice that was submitted by an
outside contractor.

Note that the above procedure requires that the EPG receive either the
Appendix D form or a copy of a submitted BAAQMD notice for every
demolition, whether or not involving asbestos, and for every removal of
RACM, no matter how small.

N. Respirators

1\. Air-purifying negative pressure respirators used by LBL personnel
who may be exposed to asbestos above the PEL or excursion limit must be
quantitatively fit-tested every 6 months. This is in addition to the
other aspects of the Respiratory Protection Program. Call extension 4028
for respirator fit testing and training.

2\. Powered air purifying respirators shall be provided free of charge
in lieu of a negative pressure respirator if an employee requests one.

3\. Respirators shall be used in all of the following circumstances.

> a\. Class I asbestos jobs.
>
> b\. Class II work where the ACM is not removed intact.
>
> c\. Class II & III work where wet methods are not used and there is
> not a negative exposure assessment.
>
> d\. Class III work where TSI or surfacing material that contains or
> may contain asbestos is removed.

4\. The Field Support Department shall perform a initial exposure
assessment of all tasks where the PEL or Excursion limit may be
exceeded. The following table will be used to select respiratory
protection, and represent minimum requirements.

O. Roofing Products - Asphalt

Asphalt roofing products containing asbestos are non-regulated (Category
I, non-friable) unless they are or will become friable, or will be
subjected to sanding, drilling, grinding, cutting, or abrading. Such
non-regulated asphalt roofing products do not need be removed or
reported prior to demolition or renovation activities. Note: Waste
Disposal sites may have individual internal requirements that
[exceed]{.underline} legal disposal requirements, be sure to contact the
Waste Management Group for guidance concerning bins, labeling & wrapping
requirements, etc. before starting work

P. Sheetrock (drywall)

When a demolition or renovation impacts a wall system composed of
sheetrock, joint compound, and tape, a composite sample will be taken of
the wall material. A wall system shown by composite sampling to contain
less than 1% asbestos is not regulated by BAAQMD, EPA, or DTSC, and may
be disposed of as construction waste. If the composite sample result
indicates a trace amount of asbestos, and/or the joint compound analysis
indicates a 1% or greater asbestos content, a EH&S Industrial Hygienist
will be contacted for further guidance before starting the work.

Q. Training

1\. Employees routinely engaged in activities that may incidentally
result in disturbance of ACM (e.g., custodial staff) must attend an
annual safety meeting at which the topic of asbestos safety is
addressed. This training will be scheduled by the supervisor. An EH&S
Industrial Hygienist will attend this meeting to provide information and
answer questions. This course shall shall cover (per 29 CFR 1926.1101
(k) (v) )the following:

A. Methods of recognizing asbestos and when to presume that a building
material contains asbestos.

B. The health effects associated with asbestos exposure.

C. The relationship between smoking and asbestos in causing cancer.

D. The nature of the operations that could result in asbestos exposure,
as well as how to minimize exposure through the use of engineering
controls, work practices, personal protective equipment, and
administrative controls.

E. The use and limitations of respirators, information on smoking
cessation programs, and medical surveillance program requirements.

F. The contents of the asbestos standard, 29 CFR 1926.1101, the meaning
and requirement for posting signs and labels.

2\. Employees identified as being potentially exposed to airborne
asbestos levels above the PEL or excursion limit shall receive OSHA
approved training. (per 29 CFR 1910.1001 (j) (7) and 29 CFR 1926.1101
(k) (iii)

3\. Employees performing bulk sampling must attend an EPA-approved
building inspector course or be a CIH (29 CFR 1926.1101 (k) (ii)(B).

4\. The Asbestos Program Manager must attend EPA approved Building
Inspector / Management Planner and Contractor/Supervisor courses, and
maintain current certification.

5\. The Industrial Hygienist whose specialty area is asbestos must
attend EPA approved Building Inspector/Management Planner and
Contractor/Supervisor courses, and maintain current certification.

IX\. Asbestos Removal and Repair Procedures

The presence, location, and quantity of ACM or PACM must be identified
at the worksite before work starts. This information must be disclosed
to the employees who will perform this work, as well as employees who
will be working in adjacent areas.

In addition, before [any]{.underline} demolition, and for
[all]{.underline} renovation work when RACM will be removed, (including
small-scale, short duration work) the Environmental Protection Group
will be informed. The Appendix A \"Asbestos Removal/Repair\" form must
be completed for [all]{.underline} removal of RACM or PACM if the amount
to be removed is less than 100 linear, 100 square feet (ft2) or 35 cubic
feet. If greater than these amounts, the Appendix D notification form,
available from the Environmental Protection Group, will be completed a
minimum of 12 working days prior to the start of work. An outside
contractor performing work that is reportable to the BAAQMD may provide
a copy of the BAAQMD reporting form instead of Appendix D. The purpose
of this requirement is to assure compliance with BAAQMD notification
requirements, see section N for further details. All exposed RACM shall
be adequately wetted and kept wet during cutting, stripping, demolition,
renovation, removal, handling and disposal. Approval for dry removal of
RACM must be received from the BAAQMD through the Environmental
Protection group.

or PACM dust or debris shall be performed by employees trained at a
minimum of a Class III asbestos work level.

3\. **Air sampling**: Sufficient frequency to document expected
exposures.

4\. **Regulated Areas**: None, employees who are trained at this level
will not work in a regulated area.

5\. **PPE / Respirators**: Not required, employees who are trained at
this level will not work in Regulated Areas or perform work that may
exceed the PEL.

6\. **Work requirements**: Wet methods. Since this type of work will
primarily involve contact with ACM flooring, see section G, \"Flooring
Material Maintenance\".

X. Waste Disposal

A. Friable ACM containing 1% or greater asbestos (RACM).

1\. All RACM waste must be handled as hazardous waste. RACM will be
thoroughly wetted before packaging, then packaged to prevent dispersion
and to facilitate handling.

2\. The Waste Management Group at extension 5867 or 5877 is responsible
for determining the Hazardous Waste Handling Facility\'s storage and
labeling requirements, selecting the disposal site, as well as
manifesting and maintaining disposal records. They will also assist in
determining how to best package the waste for disposal and arranging
site pickup.

3\. Packaging

*Labels*: All containers of RACM must bear the asbestos warning label
(Appendix C, Fig. C-1) and the \"Hazardous Waste\" label.

*Bags*: Asbestos waste must be sealed inside two layers of 6-mil
thickness plastic bags after thorough wetting. The inside and outside
bags shall be separately sealed. The excess air in the bag shall be
removed by a HEPA vacuum. The outer bag must be labeled as shown in
Appendix C, Fig C-1.

*Drums*: Wetted asbestos waste can be contained in properly labeled DOT
spec. 17H 55-gal steel drums equipped with polyethylene drum liner bags.

B. Non-friable ACM (transite, floor tile etc.)

Contact the Waste Management Group at extension 6012 for assistance with
labeling, storage, and disposal requirements. Labels may not be
necessary if non-friability can be demonstrated (29 CFR 1926.1101
(k)(7)(A)).

a The Asbestos Inspector, Building Manager, or Asbestos Program Manager
shall make recommendations from the response options listed above only
after an Inspection/Reinspection or Periodic Surveillance.

b Apply encapsulant.

c Enclose (isolate) the space only where necessary to protect human
health and environment.

d Operations and Maintenance (O&M) Program if ACM is [not]{.underline}
removed, which will include inspection, labeling, preventative
maintenance, and other apropriate controls.

e An O&M Program, alone, is appropriate if no corrective action is
warranted. The recommendation to correct ACM that is not damaged
includes an assessment of the \"potential\" for future
damage/disturbance.

f Corrective action immediately (\<1 day) or seal off the area if
friable, if non-friable type of material contact an Industrial Hygienist
(IH) to determine the appropriate repair schedule.

g Corrective action ASAP (within 5 days) if friable, if non-friable type
of material contact an IH to determine the appropriate repair schedule.

h Corrective action within 30 days if friable, if non-friable type of
material contact an IH to determine the appropriate repair schedule.

Appendix G - Bulk Sampling Procedure

**APPENDIX G**

Bulk Sampling Procedure

1\. Wear a high efficiency particulate respirator. Protective clothing
may also be necessary in some instances.

2\. Be prepared to clean-up and/or contain debris created by the
sampling process.

3\. Utilize core samplers such as small hollow \"bits\" to drill into
insulation. (Bit may be 5mm (3/16) thin wall brass tubing 6-7 mm (3
inches) long and sharpened on one end). One bit is used for each sample.
Bit is chucked up in a slow (\<500 rpm) battery powered drill.

a\. Place moist sponge over area to be sampled.

b\. Turn-on drill and with gentle but firm pressure bore the hollow bit
tharough the sponge and insulation until contact is made with the
underlying structure. (Be careful not to damage copper pipes). With bit
still rotating, the core is withdrawn back through the wet sponge. Turn
off the drill.

c\. Place plastic bag around the tubing and end of the bit, then release
the tubing into the bag. Seal and label bag, then record the sample into
the logbook. Note sample number on adjacent insulation with indelible
marker.

d\. Repair sampling damage by filling the hole with caulking material.

e\. Pack sample for shipment to the laboratory. In order to analyze, the
laboratory will push the core through the hollow bit.
