2.0 INSPECTION DESCRIPTION

An asbestos survey was performed on the Pinal County Building F on September 17, 2019, by Ole

A. Solberg, P.E. and Alexis Solberg, as requested by Hattie Sturgill of Pinal County Dept of

Facility Management. The purpose of this survey was to identify asbestos-containing materials

(ACM's) used in the construction of the building prior to demolition. This survey was performed

in general accordance with the guidelines set forth in U.S. Environmental Protection Agency

(EPA) 40 Code of Federal Regulations (CFR) Part 763 Asbestos-Containing Materials in Schools:

Final Rule and Notice (AHERA), and 40 CFR Part 61 National Emission Standards for Hazardous

Air Pollutants (NESHAP); Asbestos NESHAP Revision; Final Rule.

This survey was destructive in nature and all accessible materials were sampled for asbestos.

Hidden pipes, locked rooms, etc. were not sampled. Commonly known building materials that

contain asbestos were assumed to contain asbestos. The sampling of the building materials (i.e.,

floors, walls, ceiling, insulation, roofs, thermal pipe insulation, and other miscellaneous materials)

were performed on a homogenous-area basis. A homogeneous material is defined as uniform in

color and texture. Friable and nonfriable materials were sampled and tested. Friable asbestos

material, as defined by NESHAP, is any material containing more than 1 percent asbestos that,

when dry, can be crumbled, pulverized, or reduced to powder by hand pressure.

Only those areas and materials identified in this report were surveyed. All other areas and materials

of construction not identified in this report must be assumed to be asbestos containing material

unless they are surveyed and or sampled by an EPA certified AHERA inspector. Forty bulk

samples were collected from the subject site during this survey. One sample was used for multiple

materials. Multiple homogenous areas were identified during the survey. None of the homogenous

areas were assumed with the presence of asbestos.

3.0 LIMITATIONS

This report has been prepared in accordance with generally accepted practices for use by the client

for evaluation purposes. The named inspector observed that degree of care and skill generally

exercised by the profession under similar circumstances and conditions.

This report does not, in any way, represent a warranty or guarantee that there are no asbestos

containing material (ACM) within the building, or within building components that are not

accessible or sampled during the survey. Destructive sampling was undertaken during the survey.

It should be noted that the ACM test program results were based on the named inspector's field

investigation and analyses of selected samples which are assumed to be representative of the

materials within the structure. It is recommended that, unless a renovation area/material has been

sampled and shown through analysis to be negative, the material should be assumed to be asbestos

containing, until sampled and analyzed for the presents of asbestos.

This report has been prepared on behalf of and for the exclusive use of Pinal County Dept of

Facility Management, solely for their use and reliance in the evaluation of this site. This report and

the findings contained herein shall not, in whole or in part, be disseminated or conveyed to any

Page 3

other party, nor used by any other party in whole or in part, without the prior written consent of

Pinal County Dept of Facility Management.

4.0 SITE INFORMATION

4.1 Site Inspection

An asbestos survey was performed on September 17, 2019, by Ole A. Solberg, P.E., an

EPA/AHERA accredited Asbestos Inspector No. 4644-4846-051819. The purpose of this survey

was to identify ACM's used in the construction of the buildings on the subject site prior to

demolition.

4.2 Site Description

The subject site is comprised of slab on grade floors with concrete masonry unit (CMU) exterior

walls with an exterior stucco. The Public Works portion has a masonry exterior and storefront

entrance/windows. The interior walls are constructed of various materials such as; steel and wood

stud with textured wallboard, and CMU walls. Floors have several carpeting materials and small

amounts of floor tile. Ceilings are mostly suspended ceiling with small amounts of textured ceiling.

The former roof in the Development Services area is made of cast concrete T bar panels. A wood

framed roof has been added with plastic tile, asphaltic rolled and shingle roofing. Some areas have

a foam roof. Some original foam roof is still apparent in the attic. The Public Works side has a

steel deck roof covered by a membrane roofing. The site is located at 31 N Pinal St, Florence,

Arizona.

4.3 Review of Building Plans

No previous building plans were available for review. A set of plans for proposed replacement

building containing the demolition plan was used to determine what areas and materials that were

to be sampled. The plans were prepared BWS Architects and labeled 95% Construction

Documents and dated August 16, 2019.

4.4 Review of Prior Surveys

My files contain a record of a previous survey dated December 16, 1997 for an inspection that I

conducted on December 10, 1997. At that time the building was being converted from the County

Jail to the current government office building. That survey reported a small amount (3.3 Sq Ft) of

duct tape and mastic were assumed to be Class II ACM and were demolished along with the non-

ACM material as the amount was under the regulatory threshold of 160 Sq Ft.

My files contain another record of a previous survey dated February 23, 2011 for an inspection

that I conducted on February 16, 2011. The inspection covered building renovations in the

Building Safety Dept. Samples of gypsum wallboard and base cove were taken and reported as

negative for asbestos. The sampled material is of the same existing construction material by

personal knowledge.

5.0 SAMPLING AND ANALYTICAL METHODOLOGY

5.1 Sampling Methods

A complete visual inspection was performed to acquaint the inspector with a total perspective of the

building. Homogenous areas were mapped where building materials of the same type; style and

composition were used in the same manner.

All of the samples were collected in general accordance with AHERA and NESHAP guidelines.

Materials were determined to be friable or non-friable by touch. Representative samples were

taken in random/convenience fashion of the homogeneous areas, using variations of the EPA

random sample pattern. Samples were obtained by physically removing a small portion of the

material using wet methods and a slicing technique. All layers of the material sampled were

penetrated, and the disturbance of the adjacent material was kept at a minimum. The sample was

then placed into a labeled container and sealed. The sampling instrument was then wiped with a

wet disposable towel to remove material that could contaminate the next sample. All samples were

labeled, identifying the sample number, then logged into a Chain-of-Custody with a brief

description of the sampling material. The sample number and a description of the homogenous

material sampled were marked on a copy of the building plans when available. The survey was

non-destructive: therefore, hidden pipe chases, locked rooms, and restricted areas were not

accessed for inspection.

Bulk samples were submitted for analysis to Fiberquant, Inc. and cross-referenced to the locations in

which they were taken to determine which areas of the structure have asbestos containing building

materials. Chain-of-Custody protocols were followed throughout the collection and analysis process.

5.2 Analytical Methods

The samples that were collected from the subject site were delivered with a proper Chain-of-

Custody to a Phoenix laboratory, Fiberquant, Inc. Fiberquant's laboratory is fully accredited by the

National Voluntary Laboratory Accreditation Program (NVLAP) # 101031-0. The analytical

procedure used for bulk samples is EPA 40 CFR, Ch 1, Pt 763, Subpart F, App A, Polarized Light

Microscopy with Dispersion Staining.

6.0 BULK SAMPLE ANALYSIS AND HOMOGENOUS AREAS

6.1 Laboratory Results

Copies of the lab results are provided in the Appendix C.

7.0 RECOMMENDATIONS

Current National Emissions Standard for Hazardous Air Pollutants (NESHAP) regulations classify

ACM into the following categories: Category I materials, Category II non-friable materials and

Category II friable materials that are called Regulated Asbestos Containing Materials (RACM).

Page 5

Category I materials are resilient floor coverings, gaskets, packing and roofing materials

containing greater that 1% asbestos. Category I materials only need to be removed from a structure

prior to demolition, renovation or repair if they are in poor condition, are friable, or would be

subjected to sanding, cutting or abrading. Category I materials that remain intact without

significant breakage would not require removal prior to demolition.

The following materials were tested positive for asbestos or was assumed to contain asbestos and

are classified as Category I material.

Building F

Old Roof Roofing Mastic – Note This mastic is on clay brick which appears to be a parapet

of the original building CMU walls. The mastic appears to be an edge sealant of the former roof

when the building was a jail.

All of the materials are in good condition and can be demolished in place.

Category II materials are all other ACM's. Category II material is broken down into two sub-

categories which are Category II non-friable ACM and Category II friable ACM. Category II

nonfriable ACM is any material, excluding Category I, containing greater than 1 % asbestos that,

when dry, cannot be crumbled, pulverized, or reduced to powder by hand. These items do become

friable during normal demolition activities and thus are considered regulated. No Category II

material was found.

RACM are any materials containing more than 1% asbestos that, when dry can be crumbled,

pulverized, or reduced to powder by hand pressure or cause an emission (Category II friable

ACM's). RACM's must be removed prior to demolition or renovation activities and disposed of in

a landfill, which has been approved to accept asbestos. No RACM material was found.

PLM The "New" Method; see below

Client:

Polarized Light Microscope (PLM) Analysis for Asbestos in Bulk Sample

Method and Analysis Information:

Each bulk sample is first dissected under a 7-30x magnification stereo-microscope. This examination is used to determine the general type of sample,

how many and what type of layers it has, and initial estimates of fiber types and quantities. Second, liquid media mounts are made of each layer -

such mounts may be of selected fibers (used solely for identification purposes) or may be representative of the layer as a whole (used for quantitation

purposes). The mounts may be made in a synthetic Canadian balsam, one of several solvents, or in refractive index oils (media of known refractive index). Generally, a variety of different mounts are made: some optimized for fiber visibility, some optimized for fiber identification, and some

optimized for fiber quantitation. The mounted slides are then examined at 50-400x magnification on a Nikon Labphot-pol microscope. Optical

characteristics are used to identify each observed fiber type; the optical data are contained for each sample on its detail analysis sheet, attached.

Current EPA and NESHAP regulations designate a result of ≤1 % asbestos as "negative" or "non-regulated"and >1 % asbestos as "positive" or

"regulated." Samples containing layers that have been determined to be "positive" may have to be handled differently during a renovation or

demolition than samples whose layers have been determined to be "negative." OSHA under CFR 1926.1101 regulates work done involving any

detectable concentration of asbestos.

The method of fiber identification and quantitation is the “Standard Operating Procedures for the Analysis of Asbestos in Bulk Samples using Polarized

Light Microscopy”, Chapter 7 of the Quality Assurance and Management Manual. This SOP and its associated reporting have been designed to satisfy all requirements in both EPA Method 600/M4-82-020 (The Interim Method) and EPA Method 600/R-93/116 (The New Method). The Interim Method is

the required method for AHERA (US EPA 40 CFR Pt. 763), but this method calls for the reporting of composited results of multi-layered samples that is

no longer an acceptable reporting practice in most circumstances. Current EPA rules, such as NESHAP (US EPA 40 CFR Pt. 61), as well as NVLAP

accreditation policies, call for separate reporting for each layer of multi-layered samples. The New Method contains the same procedures for identification and quantification of asbestos as does the Interim Method, except that multi-layered samples are reported to comply with the latest US

EPA rule. Fiberquant not only reports the asbestos content of each layer of multi-layered samples separately (satisfying current EPA and NVLAP

reporting requirements), but Fiberquant also reports what percentage of the sample each layer comprises. Therefore, the results may be

arithmetically composited to satisfy the reporting requirements of the Interim Method. The method of fiber quantitation is an estimation technique in which the analysts quantitation is routinely calibrated by reference quantitation standards, and which has been shown to be equivalent in precision

and accuracy to point counting. Friability is estimated for the purposes of deciding when to point count. Friabilities determined in the field take

precedence over those determined in the laboratory. Those sample layers which are friable and estimated by the analyst to contain <= 1% asbestos are point counted using 400 points. Such point counting is required by NESHAP (National Emission Standards for Hazardous Air Polutants, Nov. 1990)

in order to rely on analytical results that are ≤ 1%. The coefficient of variation for the estimation quantitation technique is 100% in the range 0-5%.

This means that PLM analysis is not capable of conclusively determining whether a layer containing close to 1% asbestos is actually "positive" or

"negative". For this reason, Fiberquant refers to results where asbestos was detected but ≤ 1% as "borderline negative", and results where asbestos was >1 % but <= 2% as "borderline positive" to indicate the uncertainty in assigning a "positive" or "negative" label. In the sample summary, "ND"

means that no asbestos was detected during the analysis. A "Tr" or "Trace" of asbestos reported is defined for our purposes as the detection of

several asbestos fibers during the analysis; this level would be right at the limit of detection for the method. Trace is only reported on the analysis

detail - in the summary a trace would be reported as <=1%. The limit of detection (the smallest % of asbestos that can be detected) varies greatly depending on the matrix in which the asbestos is found. As little as 0.001% asbestos can be detected in favorable samples, while detection in

unfavorable samples may approach the detection limit of 1% stated in the method. During the analysis, the analyst, for Fiberquant identification

purposes only, determines the "apparent sample type" and "apparent layer types." It must be emphasized that these types are only what is

apparent. Often, different materials appear similar or identical after sampling, so the analyst may assign a type other than what was sampled.

Floor tiles present a special problem for PLM asbestos analysis. Floor tile can contain chrysotile fibers so thin that they cannot be resolved by optical

methods. In such a case, we may observe a percentage of asbestos which is lower than the actual percentage, or not observe asbestos at all when some is present. For this reason, floor tiles reported as negative should be confirmed to be negative using transmission electron microscope (TEM)

analysis. Likewise, vermiculite insulation materials containing traces of asbestiform asbestos present a problem for routine PLM analysis - the

amphiboles are sometimes present in trace amounts inhomogeneously distributed. For this reason, loose vermiculite samples reported as negative

should be confirmed to contain no amphibole using hydroseparation techniques.

The samples were analyzed under the following ongoing quality assurance program: Blank samples are routinely analyzed to maintain contamination-

free materials. Each analyst has at least a bachelor's degree in physical science, and has also completed extensive training specific to asbestos

analysis for 1-3 months before being allowed to analyze client samples. Qualitative reference samples are routinely analyzed to assure that analysts

PLM Analysis Summary: Job Number: 201909022 219044 Pinal County Bldg F

can identify asbestos and asbestos-look-alike fibers. Quantitative reference samples are routinely analyzed to calibrate and characterize the

estimation procedure. Microscope alignment is checked each day. Refractive index oils are calibrated at least quarterly. At least 10% of client

samples are re-analyzed from scratch by a different analyst than the original, and any discrepancies are resolved for the sample and similar sample types before the results are reported. All quality checks performed for these samples were in control except as detailed in the "Analytical Notes"

below. All analysts participate in interlab round robins and proficiency testing to assure competence. Fiberquant is accredited by NVLAP (Lab code

#101031) for the analysis of bulk samples for asbestos using PLM. Accreditation does not imply endorsement by the EPA, any other United States governmental agency or any private agency or association. Each lab analysis refers only to the sample tested, and may not, due to the sampling

process, be representative of the material sampled. This report may not be reproduced except in full, without the approval of Fiberquant Analytical

Services.

Job Analysis Notes:

Some results may have been calculated using client supplied data, such as volume or area sampled, for which Fiberquant assumes no liability for accuracy.
