Action Needed Asbestos removal by California certified asbestos workers is necessary prior to disturbance of these materials.
Exercise caution during construction and notify a certified asbestos consultant (CAC) for sampling if additional
suspect ACMs are found and will be disturbed.
Lead Paint XRF Testing Result Summary
No lead-containing components were identified by XRF testing2.
Action Needed
No action needed. Cal/OSHA requires that renovation or demolition work performed on components containing
lead concentrations above 600 parts per million (ppm) must be performed with appropriate personal protective
measures until employee exposure assessments establish that air concentrations are below the lead permissible
exposure limit (PEL). Removal or stabilization of LBP components should be performed by CDPH certified lead
workers.
Lead Paint Chip Sample Result Summary
The following paints were identified with lead concentrations above 600 ppm by laboratory analysis:
➢ Grey Exterior Walls & Fascia – 936 East 3rd Street
Please note: Bulk paint sampling was only performed for damaged exterior paint. Intact paint may contain lead
above 600 ppm as well.

4.0 ASBESTOS
4.1 Laboratory Analysis
The bulk samples collected were analyzed for asbestos by Polarized Light Microscopy (PLM) using
the Environmental Protection Agency (EPA) Methods EPA/600/R-93/116 and EPA/600/M4-82-020
by the following National Institute of Standards and Technology’s (NIST) National Voluntary
Laboratory Accreditation Program (NVLAP) accredited laboratory:
Laboratory QuanTEM Laboratories, 2033 Heritage Park Drive, Oklahoma City, OK
4.2 PLM Results (Visual Estimation)
Polarized Light Microscopy (PLM) is the method most often used for the analysis of
construction/building materials for the presence of asbestos fibers. The method utilizes the unique
features of polarized light to observe mineral specific optical properties in prepared samples. In this
manner, PLM can differentiate asbestos from non-asbestos fibers and further classify the various
types of asbestos. The PLM procedure is an economical technique for screening a large number of
-

Inspection, Assessment, Sampling Report
Page 7
samples; however, there are limitations due to the magnification (100-400X) employed and due to
other interferences present in the building material matrices. PLM results are reported as a
percentage of the total sample. The method utilizes two protocols for the quantification process,
which include visual estimation and point counting. Depending on the sample matrix, PLM
analytical sensitivity can be a fraction of a percent. Gravimetric reduction protocols further enhance
this technique's ability to accurately quantify and qualify asbestos.
The collected samples were grouped into homogeneous categories, assigned individual sample
numbers, sealed in plastic bags, and transported under proper chain-of-custody documentation to
the selected laboratory.
The following is a summary of the materials that were determined to be asbestos-containing. A list
of the materials that were determined to not contain asbestos fibers are listed in Table 3. Most
asbestos-containing materials must be removed prior to any renovation or demolition. Abatement
contractors shall verify ACM quantities prior to providing bids for removal work.

4.3 PLM by 1000-Point Count Analysis with Gravimetric Reduction
In PLM point counting analysis, a graticule containing a crosshair is placed in the ocular (eye piece)
of the microscope. The place at which the crosshairs meet is known as the “point”. The analyst
-

Inspection, Assessment, Sampling Report
Page 8
moves the slide around under the microscope until the “point” lands on a particle. If it is visually
identified as an asbestos fiber the point is counted as an asbestos point. If it is visually identified as
a non-asbestos particle, the point is counted as a non-asbestos point. If the point falls on an empty
area of the slide nothing is counted and the slide is moved to a new field of view. The process is
repeated until 400 to 1000 asbestos and non-asbestos points are counted. The total number of
asbestos points is found and is divided by the total number of points counted (both asbestos and
non-asbestos). The result is multiplied by 100 to obtain the percent of asbestos in the sample.
Gravimetry is a technique that enhances PLM in the quantitation of asbestos in bulk building
materials by eliminating or significantly reducing the organic matter in the sample (the asbestos
fibers remain). It improves the ability to detect asbestos fibers in the sample and also improves the
quantification. Prior to slide preparation, the sample is dried, weighed and placed in a high
temperature (up to 500 C°) furnace for a 6-hour period. It is then cooled and weighed. Further treatment with dilute hydrochloric acid may be used to remove carbonates and other acid soluble
substances in the sample. The remaining material is then washed with water, dried and weighed.
The residue is now examined by PLM or other techniques for the presence of asbestos fibers.
Using PLM point counting is performed to determine the concentration of asbestos fibers in the
residue. Once the point count result is obtained, the weight of the residue is used to calculate the
concentration of asbestos in the original sample.
The following table lists the samples that were additionally analyzed by the 1000-point count
method.

Additional analysis using the 1,000-point count method demonstrated that the above materials
contains trace amounts (between 0.1% and 1%) of chrysotile asbestos. Materials containing trace
asbestos are not regulated by the SCAQMD and can be disposed of as construction debris; however,
they are regulated by Cal/OSHA. An initial exposure assessment should be conducted in
accordance with Title 8 CCR section 1529 during any disturbance of this material. The estimated
amount present is 3,000 square feet.

4.4 Types of Asbestos-Containing Materials
All ACMs must be removed prior to any renovation or demolition activities that could result in
damage or disturbance. Regardless of the quantity estimates provided above or in the narratives
below, the abatement contractor must verify the quantities of all ACMs prior to bid submission.
Regulated Asbestos-Containing Material (RACM) is (1) a friable asbestos-containing material,
(2) a Category I non-friable ACM that has become friable, (3) a Category I non-friable ACM that
will be or has been subjected to sanding, grinding, cutting or abrading or (4) a Category II non-
friable ACM that has a high probability of becoming or has become crumbled, pulverized, or
reduced to powder by the forces expected to act on the material in the course of demolition or
renovation operations. An initial exposure assessment should be conducted in accordance with Title
8 CCR section 1529 during any disturbance of these materials.
Friable refers to any material containing more than 1% asbestos as determined by Polarized Light
Microscopy (PLM), that, when dry, can be crumbled, pulverized or reduced to powder by hand
pressure.
Category I ACM (Non-Friable) refers to asbestos containing packing, gaskets, resilient floor
covering, Galbestos™ siding and roofing, and asphalt roofing products containing more than 1%
asbestos. Asphalt roofing products, which may contain asbestos, include built-up roofing; asphalt-
containing single ply membrane systems; asphalt shingles; asphalt-containing underlayment felts;
asphalt-containing roof coatings and mastics; and asphalt-containing base flashings. ACM roofing
products that use other bituminous or resinous binders (such as coal tars or pitches) are also
considered to be Category I ACM.
Category II ACM (Non-Friable) refers to any material that contains greater than 1% asbestos and
is not friable and is not a Category I ACM. Category II includes asbestos-cement shingles, tiles, and
transite boards or panels containing more than 1% asbestos. In general, Category II ACM is more
likely to become friable when damaged than is Category I ACM.
4.4.1 Friable (RACM)
No regulated asbestos-containing materials were identified.
4.4.2 Category I Non-Friable ACM

Asbestos-containing white speckled 12” by 12” VFT is located in the 2nd floor office area of 308-
310 Breeden Street/1001 E. 3rd Street. This material contains between 3% and 4% chrysotile
asbestos and is presently in good condition. The estimated amount present is 1,050 square feet.
Grey/Black Penetration Tar
Asbestos-containing gray/black penetration tar is located on the roof of the South East offices of
936 E. 3rd Street, and the roof of 308-310 Breeden St./1001 E. 3rd Street. These materials contain
20% and 25% chrysotile asbestos and are presently in good condition. The total estimated amount
present is 210 square feet.
Black Roofing
Asbestos-containing black roofing is located on the roof of the former post office building at 927-
929 E. 3rd Street. This material contains 10% chrysotile asbestos and is presently in damaged
condition. The estimated amount present is 750 square feet.
4.4.3 Category II Non-Friable ACM
Transite Pipe
Asbestos-containing transite piping is located in the hallway hot water heater closet near the men’s
restroom of 1028/1030 E. 4th Street. This material was assumed positive and is presently in good
condition. The estimated amount present is 15 linear feet.
White/Tan Joint Compound
Asbestos-containing joint compound is located in the North West area of the warehouse in 308-310
Breeden Street/1001 E. 3rd Street. This material contains 3% chrysotile asbestos and is presently in
fair condition. Additional analysis using the 1,000-point count method demonstrated that the above
materials contains trace amounts (between 0.1% and 1%) of chrysotile asbestos. Materials
containing trace asbestos are not regulated by the SCAQMD and can be disposed of as construction
debris; however, they are regulated by Cal/OSHA. An initial exposure assessment should be
conducted in accordance with Title 8 CCR section 1529 during any disturbance of this material.
Because joint compound cannot be separated from drywall (or skim coat), these materials are
considered integral systems, and both must be treated as trace asbestos-containing for
removal/disposal purposes. The estimated amount present is 3,000 square feet.
Tan Window Putty
Asbestos-containing tan window putty is located on the windows in the oil storage areas of 927-929
E. 3rd Street. This material contains 4% chrysotile asbestos and is presently in fair condition. The
estimated amount present is 150 square feet.

5.0 LEAD PAINT
5.1 XRF Testing Results
Lead XRF testing was performed in the scope of work areas to identify components containing lead
above the established action level or threshold of 1.0 milligram per square centimeter (mg/cm2). In
addition, the current condition of the tested paint/coating was noted. Ceramic tile was also tested to
identify the presence of lead in the glazing.
Prior to the start of testing and at the end of the test period (or 4 hours, whichever is less), Altec
recorded pre- and post-calibration readings on a calibration form. Altec recorded the XRF readings
on data sheets which are presented in Appendix E. Please note that many additional confirmatory
and/or quality assurance readings were taken during the inspection, but listing each of the additional
tests/readings along with the locations, material assessment, etc. would require an exhaustive effort
that was not part of the scope of work.
None of the components tested were found to be above 1.0 mg/cm2 by the XRF analyzer. CDPH3,
EPA and HUD define LBP as paint or other surface coating that contains any amount of lead equal
to or in excess of 1.0 mg/cm2 or more than 0.5% by weight. It must be understood that
painted/coated materials that contain lead at concentrations of less than 1.0 mg/cm2 still contain
lead, but these lesser amounts have been determined to be “safe” by CDPH, EPA and HUD.
Cal/OSHA does not recognize the use of XRF devices and the units of measure obtained through
the use of XRF (mg/cm2). Cal/OSHA considers concentrations below 600 ppm “safe” and requires
bulk paint chip sampling and/or air sampling for exposure assessment purposes to determine
regulatory compliance for worker protection. This information should be provided to the
renovation/demolition contractor. See Section 5.2 for additional information.
A complete list of all test locations can be found within the XRF data sheet which is provided in
Appendix E.
5.2 Paint Chip Sample Collection and Laboratory Analysis
Bulk paint chip sampling and employee exposure assessment are activities/obligations for the
demolition/renovation contractor as part of their compliance with Cal/OSHA worker protection
regulations.
Solely to assist the renovation/demolition contractor in complying with Cal/OSHA worker
protection requirements, Altec collected one or more bulk sample from damaged or deteriorated
painted components to obtain lead analysis so that the concentrations can be compared to
Cal/OSHA’s lead paint threshold of 0.06% dry weight (or 600 ppm). These samples were collected
for damaged or deteriorated painted components that were found to contain lead concentrations
below the positive threshold (either 1.0 mg/cm2 or as established by local jurisdiction).
Cal/OSHA (CCR Title 8 Section 1532.1 (d)(5)(B)) indicates that surface coatings or materials that
contain lead at concentrations below 0.06% dry weight (or 600 ppm) do not constitute a health
3 CDPH (Title 17 CCR Division 1, Chapter 8, Section 35033).

hazard to employees engaged in typical lead-related construction work. This means that
construction work involving materials below 0.06% or 600 ppm of lead can be performed without
the customary employee protection provisions (respiratory protection, protective clothing, clothing
change areas, hand washing facilities, biological monitoring, and training), which are otherwise
necessary until employee exposure monitoring shows that airborne lead concentrations are shown to
be below the lead PEL of 50 mg/m3. When construction work involves materials containing lead in
concentration at or above 0.06% or 600 ppm, Cal/OSHA requires that employers must first perform
exposure determinations to document that employee exposures are below the lead PEL before
employees can perform such work without the worker protection measures.
The samples were submitted to a National Lead Laboratory Accreditation Program (NLLAP)
accredited laboratory for analysis by EPA 600/R-93/200 Preparation Modified, EPA Method 7000B
Analysis Modified (which is equivalent to ASTM E 1729 – Standard Practice for Field Collection
of Dried Paint Samples for Subsequent Lead Determination).
Laboratory QuanTEM Laboratories, 2033 Heritage Park Drive, Oklahoma City, OK

plans to manage asbestos in schools; and to carry out plans in a timely fashion. This rule also provides an
opportunity for parents, teachers, and other school employees to become familiar with and involved in
their school’s asbestos management program. School officials are required to notify parent, teacher, and
employee groups about asbestos-related activities.
Asbestos School Hazard Abatement Reauthorization Act (ASHARA) – passed in 1990, required
accreditation of personnel working on asbestos activities in schools and public and commercial buildings.

Soluble Threshold Limit Concentration (STLC) - Laboratory analysis that determines the soluble
portion of the analytes in a sample. This procedure is used when determining the hazardous waste
characterization under California State regulations defined in Title 22 of the California Code of
Regulations (CCR). The STLC is a waste extraction test performed to determine if there are toxic
concentrations of lead in the leachate formed from the specific material tested. This analysis determines
the amount of lead that is soluble in the Waste Extraction Test (WET) leachate. This WET procedure is
used for solid samples or for samples containing
-
weight of a 0.2M sodium citrate buffer for 48 hours. This leachate is then analyzed to determine the
soluble concentrations.
Total Threshold Limit Concentration (TTLC) – laboratory analytical test that determines the total
concentration of lead (or other target analyte) in a sample.
Toxic Characteristic Leaching Procedure (TCLP) – Laboratory analysis that determines the soluble
portion of the analytes in a sample. This is a federal guideline and differs from the State in several ways.
The alkalinity of the sample must first be determined in order to know which of two different extraction
fluids should be used for the procedure. Samples with a low alkalinity use extraction fluid #1 which is a
sodium acetate solution with a pH of 4.93. Samples with a high alkalinity use extraction fluid #2 which is
a dilute acetic acid solution with pH of 2.8. The sample is then tumbled in the appropriate extraction fluid
for 18 hours.

Asbestos Definition
Asbestos is a term used to describe six different naturally occurring mineral fibers found in certain rock
formations. Asbestos fibers can be found in relatively low levels nearly everywhere in the environment.
Prior to 1980, asbestos mineral fibers were used extensively as matrix components during the
manufacturing of building materials and products. Asbestos became a popular building material
component due to the strength of the fibers, their resistance to heat and corrosion and their tremendous
insulation and acoustic properties. Due to the fibers small size and weight, once airborne (during
demolition or after damage), they can remain suspended for many hours. Airborne releases pose a
potential exposure condition because the inhalation of airborne asbestos fibers can cause serious health
problems including cancer.
Asbestos Regulatory Overview
In an effort to summarize California’s development of asbestos regulations, it is necessary to briefly
describe essential state regulations enacted to identify, control and prevent exposure to toxic chemicals in
the business environment. Requirements imposed in 1986 by the State of California within Proposition 65
(Safe Drinking Water and Toxics Enforcement Act) established criteria for the listing and publication of
chemicals known to cause cancer or reproductive toxicity. A portion of Proposition 65 imposes
prohibitions regarding exposure to regulated materials, toxins and listed chemicals (of which asbestos is
included) without prior warnings to inhabitants of a building by a property owner or property manager.
The EPA has issued an interim final rule revision of its Model Accreditation Plan (MAP) to clarify the
types of training requirements necessary for asbestos-related work in schools. California’s Connelly Bill
(Assembly Bill 2588 - The Toxics Hot Spots Act) which was passed in 1987 requires that the California
Air Resources Board develop a list of toxic air contaminants for which emissions must be reported and
regulated. The Connelly Bill extended requirements for notification regarding the location, condition,
status, and health risks associated with ACM in areas of public, private and commercial building which
are accessible to the building’s occupants. These requirements extend to employees, tenants, maintenance
personnel; independent contractors and all other performing work in the building or facility. In 1986,
Congress enacted the Asbestos Hazard Emergency Response Act (AHERA or TSCA Title II), which
mandated a regulatory program to address asbestos hazards in schools. In 1990, Congress enacted
Asbestos School Hazard Abatement Reauthorization Act (ASHARA) that amended AHERA to extend
some of the training, accreditation requirements, and sampling protocol to persons performing asbestos-
related work in public and commercial building.
The key elements to AHERA/ASHARA regulations require the development of an Operations and
Maintenance (O&M) Program if friable ACM (or non-friable ACM which will become friable) is present
in a building.
Asbestos Sampling Protocol
The sampling protocol established within AHERA (extended to commercial buildings by ASHARA) was
used to determine the required number of samples for this survey based on the type, number and location
of homogeneous building materials. AHERA protocol was used to determine homogeneous areas of
construction in the building. Three forms of asbestos are typically found in buildings: (1) sprayed- or
toweled-on surfacing materials, (2) insulation on pipes, boilers and other mechanical equipment, and (3)
miscellaneous forms such as floor tile, ceiling tile, roofing materials, wallboards, window glazing, etc.
AHERA recommends the collection of a minimum of nine (9) samples for each suspect asbestos-
containing material (ACM). However, the minimum numbers of samples required by AHERA for
sampling purposes are listed in the following table:

polarized light using microscopes with a special optical lenspiece5. Optical characteristics of the fibrous
material reveal the mineralogy of the fibers. Asbestos fiber content is estimated by optically comparing
the quantity of non-asbestos material to asbestos fibers. The lower limit of reliable detection using PLM is
1%. Samples that contain more than 1% asbestos fibers are reported in percent ranges. Samples that
contain asbestos fibers in a concentration lower than 1% are reported as “trace” or “

Asbestos Limitations
The work that was performed during this inspection was done at the request of the client or the client’s
representative. The investigation was completed in a non-destructive manner. No repairs of the materials
sampled were performed. If the building or buildings were occupied during the inspection, additional
inspection may be necessary after the building(s) are vacant but prior demolition and renovation to ensure
that there are no additional suspect ACMs present.
As previously mentioned, suspect ACMs may exist in inaccessible or hidden areas of the building(s) and
these materials may not have been identified or sampled such as but not limited to thermal system
insulation (TSI), ceiling or wall insulation, flooring materials below sub-floors, and Transite™ pipes. The
quantifications of the suspect ACMs are estimates made at the time of sampling and should be verified by
perspective asbestos abatement contractors to determine exact quantities and the accessibility of the
specific materials.
The opinions and conclusions presented here are based on field observations and are consistent with
practices and actions of consulting professionals in the asbestos and industrial hygiene fields.

LEAD
Overview
Lead in painted and/or coated materials can cause potential health problems for occupants. Lead is highly
toxic and exposure to it can affect every system of the human body, it is often found in painted and coated
surfaces. The groups most at risk to lead exposure are fetuses, infants and children under the age of 6;
however, older children and adults also suffer severe damage from lead exposures. Most lead-poisoned
children are exposed in their homes. At high levels, exposure to lead can cause death. At low levels, lead
exposure affects children’s developing brains and nervous systems, causing reductions in IQ, attention
span, learning disabilities, hyperactivity and behavioral problems. The vast majority of childhood lead
poisoning cases go undiagnosed and untreated because most poisoned children have no “obvious”
symptoms. Most exposures occur through typical hand to mouth contact (ingestion) from lead dust
accumulations on floors, window sills and/or from contaminated soil in play areas. Performing a lead
inspection (or a lead risk assessment) and correcting lead hazards are essential steps in maintaining a lead
safe space.
Lead Paint Testing Protocol
The lead testing was patterned after the lead-based paint inspection protocol in Chapter 7 of the EPA
Housing and Urban Development (HUD-2012) Guidelines for the Evaluation and Control of Lead-Based
Paint Hazards in Housing. It was not Altec’s intention to conduct an evaluation of lead-based paint
hazards in complete accordance with HUD guidelines because the tested structures will be renovated or
demolished. HUD lead inspection/risk assessment protocol generally requires a very extensive sampling
strategy and documentation that is beyond the scope of work established for this project.
Altec used a portable hand held XRF spectrum analyzer to test the painted/coated building components.
HUD recommends that lead concentrations be reported in mg/cm2, which essentially is a recommendation
for the use of XRF analyzers. The reasoning behind their recommendation is that the results reported in
mg/cm2 do not change based on the number of layers of non-lead paint or coatings present at the test
location. Results that are reported in weight percent or parts per million change depending on the number
of layers of non-lead paint/coating and based on how much, if any, substrate is removed and included
within the sample. In addition, XRF results can usually be obtained without damaging the painted/coated
surface.
Within each individual interior space or room of the facility, at least one representative surface of each
unique painted/coated component (called a testing combination by HUD) was tested. At least 4 readings
are taken for the walls (each from a different wall) within a room/area. In most cases, duplicate/multiple
XRF readings were taken of similar testing combinations within a single space/room. It is not uncommon
to have an excess of 50 components tested per warehouse, shop area or mechanical space at industrial
facilities. Exterior surfaces/components associated with each structure and the equipment racks, tanks,
pipes, supports, etc. on or near the structure were tested in the same manner. The individual XRF readings
were entered into an electronic XRF data sheet, along with information regarding the room/space, floor,
test location, component, substrate, visible color and whether the paint appeared intact.
Painted surfaces with XRF readings of 1.0 mg/cm2 or above are considered positive; other jurisdictions
have stabled more conservative positive thresholds for lead based paint such as in Los Angeles County
where the positive threshold is 0.7 mg/cm2. It must be understood that painted/coated materials that
contain lead at concentrations of less than 1.0 mg/cm2 (or the applicable positive threshold) still contain
lead, but these lesser amounts have been determined to be “safe” by EPA and HUD, CDPH or other
regulatory agency. Cal/OSHA, however, does not consider these concentrations “safe”, and requires bulk
sampling and/or air sampling for exposure assessment purposes to determine regulatory compliance for
general industry or construction work.
-
It should be noted that Cal/OSHA regulations require that any renovation or demolition work performed
on components containing any detectable lead (typically above 600 ppm) must be performed by lead
certified workers until an exposure assessment establishes that the exposures are below the lead action
level in air.
Lead testing was performed using a RMD LPA-1 XRF spectrum analyzer; the Performance Characteristic
Sheet (PCS) for the model unit is provided within the Appendix section of this report. The device was
operated in accordance with the manufacturer’s instructions in addition to the procedures described in
Chapter 7 of the HUD Guidelines. The unit was operated in the “Quick Mode”. The exposure duration
required for each result was based on the actual reading relative to the designated action level, the age of
the radioactive source and the substrate on which the reading was taken. When using the an XRF analyzer
in the “Quick Mode”, substrate corrections are not necessary if the readings are taken on brick, concrete,
drywall, metal, plaster, stucco or wood.
The XRF device’s calibration was verified according to the manufacturer’s specifications in compliance
with the LPA-1 PCS. Altec performed field calibration checks at the beginning of the inspection, at least
once per 4 hours of inspection work and once again before the XRF analyzer was turned off or was
moved offsite to a second inspection location. A calibration check consists of three or more readings
taken using NIST Standard Reference Material (SRM) with paint film having a lead concentration nearest
to 1.0 mg/cm2.
Individual XRF readings are recorded on XRF Data Sheets. Any future changes in action levels by
regulating agencies may affect the classification of results. If such action level changes occur the XRF
results can be reinterpreted and new classifications can be made. No additional XRF testing is necessary.
HUD and EPA recommend that lead concentrations be reported in mg/cm2, which essentially is a
recommendation for the use of XRF analyzers. The reasoning behind their recommendation is that the
results reported in mg/cm2 do not change based on the number of layers of non-lead paint or coatings
present at the test location. Results reported in parts per million or weight percent change depending on
the number of layers of non-lead paint/coating and based on how much, if any, substrate is removed and
included within the sample. In addition, XRF results can usually be obtained without damaging the
painted/coated surface.
Use of XRF Device
In accordance with the HUD and EPA recommendations, lead testing was performed using an XRF
analyzer. The specific unit used was a RMD LPA-1 and its PCS is provided as an appendix to this report.
The device was operated in accordance with the manufacturer’s instructions in addition to the procedures
described in Chapter 7 of the HUD Guidelines. The unit was operated in the Lead-In-Paint K&L Variable
Reading Time Mode. The exposure duration required for each result was based on the actual reading
relative to the designated action level, the age of the radioactive source and the substrate on which the
reading was taken. When using the an XRF analyzer in the Lead-In-Paint K&L Variable Reading Time
Mode, substrate corrections are not necessary if the readings are taken on brick, concrete, drywall, metal,
plaster, stucco or wood.
The XRF device’s calibration was verified according to the manufacturer’s specifications in compliance
with the PCS developed and approved for the specific instrument.
Altec performed field calibration checks at the beginning of the inspection, at least once per 4 hours of
inspection work and once again before the XRF analyzer was turned off or was moved to a second
-
inspection location. A calibration check consists of three or more readings taken using NIST Standard
Reference Material (SRM) with paint film having a lead concentration nearest to 1.0 mg/cm2.
Readings from the instrument produce a 95% confidence level that the reading accurately reflects the
actual concentration of lead in the tested surfaces, relative to the 1.0 mg/cm2 action level.
Lead Bulk Samples
If included in the scope of work, Altec collected bulk samples from the tested paint/coatings to assist in
future construction planning. Components are first grouped into homogenous groupings that appear to
have a similar function, construction and painting history. Representative samples are usually collected
only for exterior components that tested below the positive threshold (either above 1.0 mg/cm2 or above
0.7 mg/cm2) by the XRF.
CCR Title 8 Section 1531 (d)(5)(B) indicates that surface coatings or materials that contain lead at
concentrations below 0.06% dry weight (or 600 ppm) do not constitute a health hazard to employees
engaged in typical lead-related construction work. This means that Cal/OSHA considered that
construction work (demolition of structures, manual scraping, and manual sanding and a few additional
tasks) involving materials below 0.06% or 600 ppm of lead can be performed without the customary
employee protection measures (respiratory protection, protective clothing, clothing change areas, hand
washing facilities, biological monitoring, and training), which are otherwise necessary until employee
exposure monitoring shows that airborne lead concentrations are shown to be below the lead PEL of 50
mg/m3.
When construction work (involving the tasks described above) involves materials containing lead in
concentration at or above 0.06% or 600 ppm, Cal/OSHA requires that employers must first perform a
negative exposure determination to prove that employee exposures are below the lead PEL before
employees can perform such work without the customary protection measures. In these situations,
employee protection measures must be used until the exposure assessment results are obtained and
confirm exposures are below the lead PEL.
In some instances, the collection of bulk samples is not practical. Bulk samples are not routinely collected
inside structures that are occupied, from interior walls, interior cabinets or floor tile, on
machinery/equipment such as CNC machines, lathes, drill presses, grinders, spray booths, resin booths,
electrical boxes and panels, storage racks, sand blasters, dust collector, scrubbers, and other machinery
which has a thin layer of paint because it would require removal of a large surface area to obtain the
minimum weight (5 grams) required for the bulk sample. Sampling these components would cause
significant cosmetic damage. Also, bulk samples are not routinely collected for powder-coated metal
surfaces because paint removal could damage the integrity of the coating or from ceramic tile which
would damage the integrity of the tile.
If performed, bulk sampling is patterned after the protocol established in Appendix 13.2 (Paint Chip
Sampling) of the HUD Guidelines. Each paint chip sample is targeted to weigh at least 5 grams to satisfy
laboratory analytical requirements. Each sample is collected from an area of approximately 2-4 square
inches. Paint is scraped directly off of the substrate and collected into plastic sample baggies or into
plastic centrifuge tubes. Attempts are made to eliminate inclusion of substrate material into the collected
sample. The bulk sample areas are not routinely measured, and therefore, the laboratory provides results
as percent lead (% lead) by weight and ppm.
Making cosmetic repairs to the paint chip sample collection locations is not part of the scope of work. To
avoid cross contamination between sample collection points, the sampling technicians wear disposable
nitrile gloves that were changed between locations and they also cleaned their chisel/scraping tool using
-
amended water and a disposable cloth after each sample was collected. The used gloves and cleaning
cloths were contained in Ziploc-type baggies and were brought back to Altec’s office for disposal.
Laboratory analysis is performed to obtain the Total Threshold Limit Concentration (TTLC) or total
concentration of lead in the material. The TTLC analysis determines the total concentration of lead (or
other target analyte) in a sample. Samples are analyzed by EPA 7420 for lead. When lead exceeds the
TTLC limit the waste is classified as hazardous. The results of this analysis can be used to determine if
analysis for STLC level is necessary by comparing 10 times the STLC limit to TTLC results. A factor of
ten is necessary to compensate for a 1:10 dilution factor that is present in the STLC analysis but not the
other. If the TTLC result does not exceed 10 times the STLC limit (5.0 mg/L for lead) then normally no
further analysis is required for waste disposal in California.
Lead Soil Assessment/Removal
While the surface coatings and paints on the exteriors of the buildings may or may not contain lead in
concentrations above 1.0 mg/cm2, most of the paint contains lead in detectable concentrations and some
are likely above 600 ppm. Therefore, there may be a possibility that open/bare soil areas along the
foundations could contain elevated lead concentrations.
To ensure proper assessment and documentation of lead concentrations in bare soil along building
foundations, Altec recommends the collection of composite soil samples prior to building demolition.
If performed, soil sampling is patterned after the protocol established in Appendix 13.3 (Collection Soil
Samples for Lead Determination) of the HUD Guidelines. The recommended sampling includes child
play areas, the building dripline around the foundation and non-play areas. The number of samples
depends largely on the size of each area and on the characteristics of the property.
Appendix 13.3 indicates that samples should be collected as follows: The number of subsamples in a
composite soil sample should be no more than ten. Generally, subsamples should be no closer to each
other than 1 ft. (0.3 m) and no farther apart than 3 ft. (1.0 m), but exceptions to this general rule are not
infrequent, due to wide variations in the pattern and extent of bare soil. The location and number of
subsamples depends on the pattern and extent of bare soil in the area being sampled. In a relatively small
contiguous area of, say, 10 sq. ft. (1.0 sq. m), a risk assessor might take one subsample from the center
and one subsample from each of two different directions from the center for a total of three. If the area is
larger, however, it would be reasonable to take more subsamples, more or less evenly spaced to represent
the area. Or, if there is quite a bit of bare soil scattered in a linear pattern along the dripline/foundation
area and extending all around the building, the risk assessor would most likely take 10 subsamples, more
or less evenly spaced.
Soil samples are collected with either a coring tool or a scooping technique. A coring tool is generally a
tube of one-half to one inch in diameter that can be forced into the ground, with a plunger that, after the
tube is removed from the ground, can push out all but the desired amount of soil. That which remains in
the tube is then pushed out into a sample container. The coring method is the preferred method if soil
characteristics allow, because it provides subsamples of uniform and reproducible size. It is not workable,
however, if the soil is loose or sandy.
The scooping method employs a spoon or small scoop or centrifuge tube with which one collects a small
amount of surface soil. Compared to the use of a coring tool, the scooping method may result in bias
toward collecting greater amounts of soil close to the surface relative to below the surface because of the
curvature of the scooping device. This method must be used, however, if the soil is loose or sandy, but
extra care must be taken to assure that the subsamples are of uniform size.
-
Neither coring nor scooping may be feasible if the soil is frozen or very hard packed. In such cases efforts
must be made to defrost or loosen the soil.
Lead Waste Characterization Samples
If requested by the client and if warranted based on the TTLC-total threshold limit concentration result,
Altec will request additional analysis to determine if the material, once it is removed and becomes a
waste, will be considered a California Hazardous Waste or a federal RCRA Hazardous Waste. This type
of analysis is performed only upon request and approval by the client.
In California, the Soluble Threshold Limit Concentration (STLC) procedure is used when determining the
hazardous waste characterization under California State regulations defined in Title 22 of the California
Code of Regulations (CCR). The STLC is a waste extraction test performed to determine if there are toxic
concentrations of lead in the leachate formed from the specific material tested. Toxic Characteristic
Leaching Procedure (TCLP) is similar to the STLC but involves characterization based on federal EPA
guidelines. The intent of the leachate extraction procedure is to simulate the conditions that may be
present in a landfill where water may pass through the deposited waste and infiltrate through the landfill,
through the underlying soil and carrying the soluble lead into the groundwater.
STLC - Soluble Threshold Limit Concentration
This analysis determines the amount of lead that is soluble in the Waste Extraction Test (WET) leachate.
This WET procedure is used for solid samples or for samples containing

Lead Removal
Demolition activities that will impact lead-based components must be performed by certified/qualified
representatives in compliance with EPA and DOSH rules and regulations. All lead-based paint
components that are deteriorated or peeling must be stabilized in accordance with all applicable
regulations prior to demolition work. A contractor who is trained and holds licenses and insurance in this
field of hazardous materials remediation should conduct any lead related removal work. Exposure
assessments and air monitoring should be conducted in the initial phases of any lead abatement to
determine the amount of personal protection required by workers. Lead components will need to be
properly packaged and characterized utilizing TTLC, STLC and TCLP laboratory analysis as necessary to
determine disposal requirements.
Lead Limitations
This inspection was planned and performed in accordance with Altec training and experience in
performing lead inspections. The inspection was performed to support renovation or demolition of the
building(s). It was NOT performed in accordance with Chapter 7 of the HUD Guidelines for the
Evaluation and Control of Lead-Based Paint Hazards in Housing. Altec’s evaluation of the relative risk of
exposure to lead identified in this survey is based solely on the conditions observed at the time of the site
visit. This project included limited lead testing and not lead risk assessment. Altec cannot be held
responsible for changing conditions that may alter the condition of the lead component surfaces after the
time of the testing or in changes in accepted protocol, methodology or action levels.
