METHODS
4.1
ACM Sample Collection Procedures
Samples of suspect asbestos-containing materials (ACMs) were collected by coring
or by carefully scraping a small portion of a surface. In areas where sampled
material posed a high risk of dust release, a half-face type H respirator equipped
with a HEPA filter was worn by the inspector for respiratory protection. The
sampled material was immediately contained in plastic ziplock bags. The sampling
information was recorded in a bound field
notebook. Samples were then properly
labeled with a unique sample identification
umber, and delivered via overnight to a
NVLAP-certified, independent laboratory
(EMSL Testing, Inc., of San Leandro,
California) for 24-hour RUSH analysis along
with the appropriate chain-of-custody
documentation.
4.2
ACM Sample Analysis Procedures
All ACM samples were analyzed using polarized light microscopy (PLM)
techniques at a state-certified independent laboratory. Samples were examined for
homogeneity and percent composition of fibrous versus nonfibrous components
using a 20x stereoscopic microscope. A small portion of the material was placed in
refractive index liquid on a microscope slide and examined for the presence of
asbestos species utilizing a polarized light microscope at a magnification of 100x to
200x. Crystallographic and dispersion-staining techniques were employed for
positive characterization. If the presence of asbestos was confirmed, the percentage
of asbestos versus non-asbestiform materials was visually estimated.
4.3
Paint Chip Sampling for Lead
Samples of suspect lead-based paints (LBPs) were collected by carefully scraping
approximately 1 gram or about 1 teaspoon-full of the paint from the substrate. The
paint was either peeled from the substrate or
scraped to the substrate, avoiding dust. ESI's onsite inspector tried to minimize the amount of
substrate submitted with the paint, as this would
affect the true concentration of lead in the paint.
The sampling information was recorded in a bound
field notebook. The paint samples were then
properly labeled and delivered to the independent
laboratory for analysis along with the appropriate
chain-of-custody documentation.
4.4
LCP Sample Analysis Procedures
Samples of suspect paint were analyzed in accordance with EPA Method 7420,
analysis by flame Atomic Absorption (AA) spectroscopy, direct aspiration, and
results were reported in percent by weight. AA spectroscopy is a laboratory
analytical technique that provides precise determination of specific inorganic
elements. These elements are more commonly referred to as “metals.” There are
approximately 65 metallic elements including lead, aluminum, tin, silver and copper.
AA refers specifically to the reaction of metal atoms to heat. When these atoms are
exposed to very high heat or are atomized in other ways, they absorb light. Each
element absorbs light of a specific wavelength and the absorption of light is directly
proportional to the concentration of atoms in solution.

REGULATIONS
The National Emission Standard for Hazardous Air Pollutants (NESHAP) regulations is
part of the Clean Air Act and is found in 40 CFR 61 part M. NESHAP requires that
building owners inspect a building (regardless of age) for asbestos prior to renovation or
demolition. The EPA must be notified in advance of all demolitions and when more than a
listed amount of Regulated Asbestos-Containing Material (RACM) are going to be
disturbed during a renovation or demolition. Furthermore, construction work disturbing
RACMs by unlicensed and non-registered asbestos abatement contractors are prohibited by
California and Federal laws.
The United States Environmental Protection Agency (US EPA) considers a material to be
asbestos-containing if at least one homogeneous sampling material confirms presence of
asbestos fibers greater that one percent (>1%). Asbestos-containing materials (ACM) are
regulated by federal, state, and local agencies.
EPA classifies ACMs into the following three (3) categories:
•
Friable ACM — Asbestos-containing materials which can be pulverized into
dust by hand pressure (definition of friability);
•
Category I non friable ACM — Asbestos-containing asphalt roofing
products, vinyl floor tiles, gaskets, sealants, and other packing material;
•
Category II non friable ACM — All asbestos-containing materials other than
Category I non-friable, that when dry, cannot be pulverized or reduced to powder
by hand pressure.
The above-referenced ACM categories can become Regulated-Asbestos Containing
Materials (RACM) under certain conditions (i.e., demolition or renovation). These
conditions are:
•
Friable ACM;
•
Category I non friable ACM which has become friable;
•
Category I non friable ACM which has been, or will be subjected to cutting,
grinding, sanding, or other abrasive contact;
•
Category II non friable ACM which has, or will be, pulverized, crumbled, or
reduced to powder under mechanical forces exerted during demolition or
renovation operations.

FINDINGS
7.1
Asbestos Containing Materials (ACM)
Based on the analytical findings of the 25 sample layers collected from the
mechanical room and ground level of Building 1400 and analyzed for asbestos, it is
confirmed that the following building material contains asbestos above the 0.1%
limit regulated by Cal/OSHA, and above the 1.0% limit regulated by EPA.
7.1.1
7.2
The wallboard joint compound throughout the entire Building 1400
(below and above ceiling surfaces) contains <1-2% Chrysotile-type
asbestos. All wallboard surfaces should be treated as ACM in this
building.
Lead-Containing Paint (LCPs)
The California Occupational Safety and Health Administration (Cal/OSHA),
considers any paint with any concentration of lead above the limit of detection
(LOD) of the analytical procedure, to be considered as lead-containing paint (LCP).
All construction or renovation work where employees may be occupationally
exposed to LCP shall be conducted in compliance with California Code of
Regulations (CCR), Title 8, Section 1532.1 "Lead in Construction."
Based on the analytical findings of the 4 paint chip samples collected from various
paints throughout Building 1400, and analyzed for lead, it is confirmed that the
following painted surfaces contain lead above the LOD of the analytical procedure,
and are thus considered to be LCP per OSHA’s definition.
7.2.1 The green-colored furnace paint in
the mechanical room of building
1400 contains 3,300 parts per
million (ppm) lead; and
7.2.2
The silver-colored paint on the
compressor tank in the mechanical
room of building 1400 contains
4,600 parts per million (ppm) lead.

RECOMMENDATIONS
8.1
ACMs
This survey was conducted in anticipation for installation of a new HVAC system in
Building 1400.
If disturbing or removing more than 100 sq. ft. of asbestos-containing material
(even below 1%), the California State License Board (CSLB) requires that the
contractor be licensed as C-22 (Asbestos Abatement), and be registered by DOSH
as an asbestos abatement contractor.
Under the United States Environmental Protection Agency (US EPA)'s National
Emissions Standards for Hazardous Air Pollutants (NESHAP) regulations, all
asbestos-containing materials shall be properly abated and disposed of, prior to
disturbance or demolition.
According to the OSHA Construction Industry Standard for Asbestos (29CFR
1926.1001), and the general industry asbestos standard (29CFR 1019.1001)
workers performing asbestos abatement must be trained, equipped with respirators
and full body protection, and be medically fit to wear respirators. Furthermore, all
removal shall be performed using wet abatement procedures and waste containing
greater than 1% asbestos shall be packaged in accordance with EPA's NESHAP
regulation (40 CFR Parts 61 and 763) and according to California Department of
Health Services (DHS), California Code of Regulations, Title 22, Division 4,
Chapter 30, Section 66699 and Health and Safety Code 25179.3 et. Seq.
During the site inspection, ESI’s field inspector determined that the following
homogeneous material contains asbestos above EPA and OSHA levels.
8.1.1
Wallboard Joint Compound
The compound and textured skim coat applied to the surface of all interior
walls throughout Building 1400 contains <1-2% Chrysotile-type asbestos.
If any wallboard throughout Building 1400 is scheduled for disturbance or cutting
during the upcoming HVAC renovation project, ESI recommends that a Statelicensed and DOSH-registered asbestos abatement contractor perform the removal
and disposal of these ACMs, under proper regulatory guidelines, and under the
supervision of the Owner’s IH consultant.

8.2
LCPs
Any construction-related demolition or cleanup where employees may be
occupationally exposed to lead shall be conducted in compliance with the California
Code of Regulations (CCR), Title 8, Section 1532.1 and 5216 "Lead in
Construction", and in accordance with Federal Occupational Safety and Health
Administration (OSHA) section 29 CFR 1926.62.
In compliance with Cal/OSHA and California Department of Public Health (CDPH)
regulations, ESI requires that an RRP-certified contractor using CDPH-certified
lead workers and supervisors conduct any demolition or debris cleanup activity that
may involve either of the following two lead containing paints:
8.2.1
The green-colored paint on the furnace of the Mechacnical room,
which contains 3,300 ppm lead; and
8.2.2
The silver-colored paint on the compressor tank in the mechanical
room, which contains 4,600 ppm lead.
Any demolition or debris cleanup shall be conducted using wet methods for dust
suppression, and work practices by the CDPH-certified lead personnel shall be such
that the 8-hour time weighted average (TWA) permissible exposure limit (PEL)
shall not exceed 50 µg/m3 . If any worker’s 8-hr TWA exposure exceeds the action
level of 30 µg/m3 , work practices causing elevated lead levels shall cease or be
modified under the directive of the IH consultant.
In addition, the contractor must continue to conduct daily personnel air monitoring,
and institute medical surveillance and training programs. If the Cal-OSHA
permissible exposure level (PEL) of 50 µg/m3 for lead is exceeded, more stringent
and additional requirements such as engineering controls, respiratory protection,
regulated work areas, and warning signs in lead work areas, become effective, as
directed by the IH Consultant.
LBP Waste Disposal
Rags and paint chips shall be treated as hazardous waste if laboratory results
indicate a lead (Pb) concentration of 5 milligrams per liter (mg/L), or greater using
the EPA-approved Toxicity Characteristic Leaching Procedure (TCLP) test or
equivalent, or greater than 1,000 mg/Kg using the total lead assay.
Building components with lead-based paint still intact (i.e., not flaking, chipping, or
blistered paint) are categorized as “Architectural Components”, and may be
disposed of as regular construction waste, as long as the paint remains intact.
Extreme care shall be exercised, however, to make sure that the intact paint on these
Architectural Components stay tightly adhered to the substrate. If during packaging,
disposal, or transport, any lead-based paint chips flake off from the Architectural
Component, all such paint chips shall be packaged as stated in the previous
paragraph, the waste properly profiled, and then disposed of.
