Asbestos Building Inspections Albuquerque Area Indian Health Service

1.0 INTRODUCTION

As requested by the Albuquerque Area Indian Health Service, bulk sampling of suspect asbestos-containing building materials was conducted on seventeen (17) buildings at the Zuni Service Unit in Zuni, New Mexico. Sampling occurred on July 9 – July 20, 2007. Bulk samples of suspect asbestos-containing materials (ACMs) were collected throughout the interior and exterior of each building. Non-destructive sampling practices were utilized during the inspections.

Federal Occupational Health (FOH) representatives Mr. Landon Johnson, Ms. Stephanie Jury, Mr. James Marshall, and Mrs. Suzette Numkena performed the asbestos inspections of the subject properties. Each inspector holds current Asbestos Hazard Emergency Response Act (AHERA) accreditation as Asbestos Building Inspectors. Certifications for each inspector can be found in Appendix 4.

Sampling of suspect asbestos-containing materials was conducted using procedures similar to the Environmental Protection Agency (EPA) AHERA regulation, 40 CFR 763. Samples were analyzed by Fiberquant Analytical Services in Phoenix, Arizona. Fiberquant is fully accredited by the EPA-required National Voluntary Laboratory Accreditation Program (NVLAP) for analysis of asbestos bulk samples using polarized light microscopy, and is also an American Industrial Hygiene Association (AIHA) accredited laboratory.

2.0 DESCRIPTION OF BUILDINGS INSPECTED

Twelve (12) of the seventeen (17) buildings inspected where all single story residential structures. The residential building types included single-family residences, multi-family residences, and detached garages. The residences ranged in size from two bedrooms to four bedrooms. In addition to the residential buildings, inspectors also inspected the Zuni Community Medical Center, the Maintenance shop, maintenance storage shop, OEH field service trailer, and the maintenance storage garage. Building floor plans for each type of structure are located in Appendix 1.

Examples of suspect building materials identified and sampled throughout each building included various floor tiles and associated mastics, sheet vinyl flooring and associated mastics, carpet mastic, concrete materials, ceramic tile, ceramic tile grout, leveling compound, stone tile, quickset tile adhesive, stone grout, residual floor mastic, gypsum drywall materials, wall texture, plaster wall materials, stucco, brick mortar, stone mortar, gypsum drywall ceiling panels, fiberboard ceiling tiles, boiler insulation, boiler gaskets, boiler tank materials/packings, putty insulation, foam filler, pipe elbow insulation, various mastics, sink undercoating, putty materials, covebase and mastic, various caulks, vapor barrier paper, and roof materials.

3.0 SURVEY PROCEDURES

Each room of each building was assigned a unique functional space number. Each functional space was visually inspected for suspect asbestos-containing materials. Materials were mapped and quantified on maps provided by the IHS or hand drawn maps.

Each suspect ACM was designated as a distinct homogeneous area, which is a single material, uniform in texture and appearance, installed at one time, and unlikely to consist of more than one type or formulation of material. The inspector touched each suspect material in order to determine friability.

A sufficient number of samples were collected of each material to satisfy the Occupational Safety and Health Administration (OSHA) and the National Emission Standard for Hazardous Air Pollutants (NESHAP) regulations for the determination of asbestos content. Bulk sample logs are located in Appendix 1.

Each sample was assigned a unique sample identification number and assessed for damage and friability classifications. The samples, with Chain of Custody documentation were delivered to Fiberquant Analytical Services in Phoenix, Arizona. Fiberquant is fully accredited by the EPA-required National Voluntary Laboratory Accreditation Program (NVLAP) for analysis of asbestos bulk samples using polarized light microscopy, and is also an American Industrial Hygiene Association (AIHA) accredited laboratory.

Laboratory analysis reports are located in Appendix 3.

The Bulk Sample Results Table (Appendix 2) provides detailed information on materials that tested positive or negative for asbestos content. A separate Bulk Sample Results Table is provided for each building inspected.

Programming Cost Estimates (Appendix 2) were developed for positive asbestos-containing materials found in each Building. The Programming Cost Estimates were derived by use of the Means Cost Guide and by consultation with experienced local contractors. The pricing reflects current industry rates. Future fluctuations in industry pricing, both natural and seasonal, may affect this estimate. In addition, Service

Units outside of metropolitan areas may incur additional costs due to travel requirements on the part of abatement contractors. For purposes of this estimate, an 18% mark-up for logistical costs is included.

This estimate is for abatement contractor costs only. Additional costs, which are not included in this estimate, are those of an environmental consultant and replacement of building materials that have been removed. The total estimated cost for the removal of asbestos-containing materials from the Zuni Service Unit is $189,157.54.

5.0 ACM DESCRIPTIONS

Descriptions of materials found to contain asbestos are as follows:

Floor tile is classified as a non-friable NESHAP Category I material. This material is currently in good condition and intact floor tile poses little to no health threat. Removal or disturbance to this material should be performed by appropriately trained and certified personnel. Removed flooring material should be disposed at a landfill that accepts non-friable asbestos waste. Landfills should be checked for acceptance of this material prior to disposal.

Floor tile mastic is classified as a non-friable NESHAP Category I material. This material is currently in good condition. Floor tile mastic that is beneath floor tile, i.e., inaccessible, poses little to no health threat.

Removal or disturbance to this material should be performed by appropriately trained and certified personnel. Removed flooring material should be disposed at a landfill that accepts non-friable asbestos waste. Landfills should be checked for acceptance of this material prior to disposal.

Sheet vinyl flooring and associated materials are classified as friable NESHAP Regulated Asbestos- Containing Material (RACM). The material is currently in good condition and intact sheet vinyl flooring poses little to no health threat. Removal or disturbance to this material should be performed by appropriately trained and certified personnel. Removed sheet vinyl flooring and associated materials should be disposed at a landfill that is approved by the Environmental Protection Agency (EPA) for acceptance of friable asbestos waste. Landfills should be checked for acceptance of this material prior to disposal.

Pipe elbow/fitting insulation is classified as friable NESHAP Regulated Asbestos-Containing Material (RACM). Intact pipe insulation poses little to no health threat. Pipe insulation inside wall cavities also poses little to no health threat. Removal or disturbance to this material is considered an OSHA Class I action, and should be performed by appropriately trained and certified personnel. Removed insulation should be disposed at a landfill that is approved by the Environmental Protection Agency (EPA) for acceptance of friable asbestos waste. Landfills should be checked for acceptance of this material prior to disposal.

Various building caulk is classified as non-friable NESHAP Category II material. The material is undamaged and poses little to no health threat. Removal of caulk and/or affected materials or other disturbance to this material, should be performed by appropriately trained and certified personnel.

Removed materials should be disposed at a landfill that accepts non-friable asbestos waste. Landfills should be checked for acceptance of this material prior to disposal.

Sink undercoating is classified as non-friable NESHAP Category II material. The material is currently in good condition and undamaged sink undercoating poses little to no health threat. Removal of this material typically involves the physical removal of the entire sink (whole) and should be performed by appropriately trained and certified personnel. Removed materials should be disposed at a landfill that accepts non-friable asbestos waste. Landfills should be checked for acceptance of this material prior to disposal.

Roofing material (Roof Shingles and Felt) is classified as non-friable NESHAP Category I material.

Removal or disturbance to this material should be performed by appropriately trained and certified personnel. Removed roofing material should be disposed at a landfill that accepts non-friable asbestos waste. Landfills should be checked for acceptance of this material prior to disposal.

Roof penetration mastic is classified as non-friable NESHAP Category I material. Removal or disturbance to this material should be performed by appropriately trained and certified personnel.

Removed penetration mastic should be disposed at a landfill that accepts non-friable asbestos waste.

Landfills should be checked for acceptance of this material prior to disposal.

6.0 PROJECT LIMITATIONS

This Project was performed using, as a minimum, practices consistent with standards acceptable within the industry at this time, and a level of diligence typically exercised by industrial hygiene and environmental consultants performing similar services.

The procedures used in this investigation attempt to establish a balance between the competing goals of limiting investigative and reporting costs and time, and reducing the uncertainty about unknown conditions. Therefore, because the findings of this report were derived from the scope, costs, time, and other limitations, the conclusions should not be construed as a guarantee that all environmental or occupational hazards have been identified and fully evaluated. Where sample collection and testing have been performed, FOH's professional opinions are based in part on the interpretation of data from discrete sampling locations that may not represent conditions at non-sampled locations. FOH assumes no responsibility for omissions or errors resulting from inaccurate information, or data, provided by sources outside of FOH or from omissions or errors in public records.

Furthermore, it is emphasized that the final decision on how much risk to accept always remains with the client since FOH is not in a position to fully understand all of the client's needs. Clients with a greater aversion to risk may want to take additional actions while others, with less aversion to risk, may want to take no further action.

PLM PLM analysis for asbestos in bulk smp

Client:

Polarized Light Microscope (PLM) Analysis for Asbestos

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, NESHAP and OSHA regulations designate a result of <=1 % asbestos as "negative" and >1 % asbestos as "positive". 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."

The method of fiber analysis and identification is the EPA Interim Method (EPA Method 600/M4-82-020). 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, and the results listed on the detail analysis sheet. 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, a "ND" means that no asbestos was detected during the analysis. A

"Tr" or "Trace" of asbestos is defined for our purposes as the detection of several asbestos asbestos fibers during the analysis; an amount essentially at the limit of detection for the method. 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. We recommend a hydro-separation technique for such samples.

Vermiculite-containing samples may contain trace amounts of asbestiform amphibole that may or may not be detected during routine PLM analysis. 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 is a degreed geologist or mineralogist, 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 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 monthly. 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 (#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
