EXECUTIVE SUMMARY

Inspection Experts, Inc. retained Argus Pacific, Inc. (Argus Pacific) to conduct a renovation-level regulated building materials assessment of the Wellpinit Service Unit - Clinic, located at 6203

Agency Loop Road in Wellpinit, Washington. Argus Pacific’s representative, Mr. Peter Snider, conducted the assessment from September 9-11, 2014. The scope of the services provided is described in Argus Pacific Proposal Number 641018P dated August 7, 2014.

Argus Pacific assessed the building for the following regulated building materials:

Asbestos-containing materials (ACM);

Assumed asbestos-containing materials;

Lead-containing coatings (paints) ; and

Radon gas.

Sixty-one bulk samples of suspect asbestos-containing materials were collected and analyzed using Polarized Light Microscopy (PLM). Three materials were found to contain greater than one percent asbestos and three materials were assumed to contain asbestos. In addition, four materials were visually assessed and determined to be non-suspect.

One-hundred and thirty-six (136) on-site X-Ray Fluorescence Spectrometer (XRF) readings were taken. Two of the XRF readings were above the EPA/HUD “lead-based paint” threshold of 1.0 mg/cm . Twenty-two readings had detectable levels of lead, but at concentrations below the

EPA/HUD threshold.

In addition to the XRF readings, Argus Pacific collected confirmation bulk paint chip samples to confirm XRF readings of paints showing no detectable concentrations of lead. Twelve confirmation paint chip samples were collected and analyzed for total lead content. Three of the

12 paint chip samples were found to contain detectable levels of lead, but at concentrations below the EPA/HUD “lead-based paint” threshold of 5,000 parts per million (ppm) by weight. Three

XRF readings, one of the white-painted interior wood window trim, one of the white-painted interior wood window sills, and one of the white-painted interior wood window casings, showed no detectable lead. However, confirmation paint chip samples were collected of these paints and the paint chip sample results did show detectable lead (below the EPA/HUD threshold). The confirmation paint chip sample results supersede the onsite XRF readings.

See Appendix B for XRF and paint chip sample results of all painted components that were sampled.

Five samples for radon were collected in the basement of the Clinic. Radon concentrations ranged from <0.5 picocuries per liter (pCi/L) to 1.1 pCi/L. Results of the radon samples were below the

EPA Indoor Guideline Action Level of 4.0 pCi/L. As per client direction, radon samples were only collected in the basement.

Radon gas.

2.0 PROJECT BACKGROUND

This report presents the results of our regulated building materials assessment of the Wellpinit

Service Unit - Clinic, located at 6203 Agency Loop Road in Wellpinit, Washington. The purpose of the assessment was to identify potential asbestos-containing material, lead-containing coatings, and radon gas (in the basement only) prior to renovation and for purposes of hazard communication and on-going management. The assessment included the interior, exterior, and roof of the east section of the Clinic building (original 1970 construction). The assessment did not include any interior or exterior areas of the building west of the original construction portion of the Clinic.

This assessment will assist Inspection Experts, Inc. with communicating the presence of lead-containing coatings and the presence, location, and quantity of ACM to employees, vendors, and contractors working in the building and to meet the requirements for an asbestos survey for the

Spokane Regional Clean Air Agency (SRCAA) and a good faith inspection as required by

Occupational Safety & Health Administration (OSHA) regulations prior to renovation or demolition. Regulations require that a complete copy of this assessment be kept in a conspicuous location on-site at all times during activities that may impact known and suspect ACM.

2.1 Sources of Information

During the course of the assessment, the following individuals and drawings provided assistance to the Argus Pacific inspectors:

Mr. Jeff Church, Federal Occupational Health

Mr. Sam Yoon, Inspection Experts Inc.

2.2 Building Description

The Wellpinit Service Unit - Clinic (also referred to as the David C. Wynecoop Memorial Clinic or DCWMC) is located at 6203 Agency Loop Road in Wellpinit, Washington. The portion of the building included in this assessment was constructed in 1970 and contains approximately 4,694 square feet of interior floor space. The building is a one-story structure with a finished basement.

The building includes office space, an exam room, storage space, restrooms, laundry/linen rooms, mechanical rooms, attic, and a fitness room.

The building is wood-frame construction with a concrete foundation. The building is heated by forced air and heat pumps located in the basement. The building interior flooring consists of glued-down carpeting, vinyl floor sheeting, and vinyl floor tiles. Interior walls consist of gypsum wallboard (no wall texture) on the main floor and textured gypsum wallboard throughout the basement and basement stairway. Ceiling materials consist of gypsum wallboard with glued-on ceiling tiles throughout the main floor and suspended ceiling tiles throughout the basement. Attic insulation consists of blown-in insulation and fiberglass batt insulation in places. Ducting is insulated with plastic-wrapped and foil-wrapped fiberglass duct insulation. Domestic water pipes are insulated with paper-wrapped fiberglass pipe insulation with plastic fittings.

The exterior consists of painted composite siding with a black asphaltic paper vapor barrier. The roof is metal and no vapor barrier was observed associated with the roof. Roof sealant associated with roof penetrations was observed but not accessible. Electrical wiring consists of thermoplastic insulation.

The area of assessment was limited to the administrative office area and basement in the east section of the building (original construction). No other portions of the building interior or exterior were included in this assessment.

3.0 ASBESTOS ASSESSMENT

3.1 Building Assessment

Mr. Snider, an Asbestos Hazard Emergency Response Act (AHERA)-accredited building inspector (Certification 147486, expiration date: 6/25/2015) from Argus Pacific, performed the sampling on September 9-11, 2014. Argus Pacific’s inspector collected 61 samples of materials identified as suspect ACM.

This assessment was conducted using a modified protocol adapted from AHERA. The protocol is as follows:

Identify suspect asbestos-containing materials.

Group materials into homogeneous sampling areas/materials.

Quantify each homogeneous material and collect representative samples. The number of samples collected of miscellaneous materials was determined by the inspector.

Samples of each material were taken to the substrate, ensuring that all components and layers of the material were included.

Sample locations are referenced on the field data forms according to sample number.

Sampling was performed by an AHERA-accredited building inspector, and the use of proper protective equipment and procedures was followed.

3.2 Sampling Procedures

This sampling was conducted using the following procedures:

1. Spread the plastic drop cloth (if needed) and set up other equipment, e.g., ladder.

2. Don protective equipment (respirator and protective clothing if needed).

3. Label sample container with its identification number and record number. Record sample location and type of material sampled on a sampling data form.

4. Moisten area where sample is to be extracted (spray the immediate area with water).

5. Extract sample using a clean knife, drill capsule, or cork boring tool to cut out or scrape off approximately one tablespoon of the material. Penetrate all layers of material.

6. Place sample in a container and tightly seal it.

7. Wipe the exterior of the container with a wet wipe to remove any material that may have adhered to it during sampling.

8. Clean tools with wet wipes and wet mop; or vacuum area with HEPA vacuum to clean all debris.

9. Discard protective clothing, wet wipes and rags, cartridge filters, and drop cloth in a labeled plastic waste bag.

3.3 Analytical Methodology

Suspect ACMs were sampled in general accordance with 40 CFR 763.86 by an Environmental

Protection Agency (EPA) AHERA-accredited building inspector. Each sample was collected and stored in a heavy-duty, self-sealing plastic bag, and delivered to Seattle Asbestos Test, LLC in

Bellevue, Washington. Samples were analyzed via polarized light microscopy (PLM) in accordance with EPA/600/R-93/116. Seattle Asbestos Test, LLC is accredited to perform PLM analysis by the National Institute of Standards and Technology National Voluntary Laboratory

Accreditation Program (NVLAP).

Asbestos-containing materials are presented in bold text. It should be noted that quality control sample locations are not shown on the Figures. The sample locations are the same as the corresponding sample ID without the “Q” designation. For example, quality control sample WSU-13-01Q was collected by breaking sample WSU-13-01 in half.

The quality control sample results for the tan tile layer were consistent with the laboratory analytical results for the corresponding materials in the main batch of samples. The black mastic associated with beige vinyl floor tile (HSA 13) was shown to contain asbestos in both the main sample results and quality control sample results.

Additional ACMs may be present in areas not assessed or that were inaccessible or concealed.

These spaces include, but are not limited to, areas and materials outside the targeted scope of this assessment, above hard ceiling decks, electrical systems, pipe chases, spaces between wall/ceiling/door/floor cavities, interior of mechanical components, beneath foundation pads, etc.

If future maintenance, renovation, and/or demolition activities make these areas accessible, Argus

Pacific recommends that a thorough assessment of these spaces be conducted at that time to identify and confirm the presence or absence of additional ACMs. Until then, all such unidentified materials must be treated as assumed ACMs in accordance with applicable federal, state, and local regulations.

If the analytical results indicate that all the samples collected per HSA do not contain asbestos, then the HSA (material) is considered a non-ACM. However, if the analytical results of one or more of the samples collected per HSA indicate that asbestos is present in quantities of greater than one percent asbestos as defined by the EPA, all of the HSA (material) is considered to be an

ACM regardless of any other analytical results (unless a representative number of samples have been analyzed by PLM point counting as described below, and the results indicate the material contains less than one percent asbestos).

Any material that contains greater than one percent asbestos is considered an ACM and must be handled according to OSHA and EPA regulations. The EPA National Emission Standard for

Hazardous Air Pollutants (NESHAP) 40 CFR 61, Subparts A and M has a requirement related to assessment of suspect ACM in buildings. When the asbestos content of a friable material is visually estimated by PLM to be detectable but less than ten percent, your firm may elect to (1) assume the amount is greater than one percent and treat the material as asbestos-containing or (2) require verification of the amount by the PLM point counting technique. If the results obtained by point counting and visual estimation are different, the point count result must be used. When no asbestos is detected by PLM, point counting is not required.

4.0 LEAD ASSESSMENT

Mr. Peter Snider, a State of Washington Department of Commerce certified lead inspector

(Certificate No. 6559 Exp. 9/18/2016) from Argus Pacific, conducted the on-site X-Ray

Fluorescence Spectrometer (XRF) readings and confirmation bulk paint chip sampling.

Homogeneous areas of suspected lead-containing coatings (paints) were identified and sampled using an XRF throughout the interior and exterior of the Wellpinit Service Unit - Clinic located at

6203 Agency Loop Road in Wellpinit, Washington. Confirmation bulk paint chip samples were collected to confirm XRF readings showing no detectable concentrations of lead.

4.1 Sampling Methodology

XRF readings were collected using a NITON Xlp 300 Analyzer. The XRF was calibrated at the beginning of the day and again approximately once every four hours until the end of the day.

4.2 Lead Sampling Results

One-hundred and thirty-six (136) X-Ray Fluorescence Spectrometer (XRF) readings were taken.

Two of the XRF readings were above the EPA/HUD “lead-based paint” threshold of 1.0 mg/cm

Twenty-two readings had detectable levels of lead, but at concentrations below the EPA/HUD threshold.

In addition to the XRF readings, Argus Pacific collected confirmation bulk paint chip samples to confirm XRF readings of paints showing no detectable concentrations of lead. Twelve paint chip samples were collected and analyzed for total lead content. Three of the 12 paint chip samples were found to contain detectable levels of lead, but at concentrations below the EPA/HUD “lead-based paint” threshold of 5,000 parts per million (ppm) by weight.

Three XRF readings, one of the white-painted interior wood window trim, one of the white-painted interior wood window sills, and one of the white-painted interior wood window casings, showed no detectable lead. However, confirmation paint chip samples were collected of these paints and the paint chip sample results did show detectable lead (below the EPA/HUD threshold). The results of the confirmation paint chip analyses are presented in Table 4.2-1 and also are included in Appendix B. See Appendix B for XRF data.

5.0 RADON ASSESSMENT

On September 9-11, 2014, Mr. Peter Snider, an Industrial Hygienist with Argus Pacific collected samples for radon in air in portions of the basement of the Wellpinit Service Unit - Clinic.

5.1 Sampling Methodology

In accordance with EPA recommendations (EPA 402-R-93-003, March 1993), Argus Pacific collected samples for radon using activated charcoal canisters. Samples were placed in occupied-space rooms approximately two feet above floor and at least two feet from perimeter walls, and the canisters were left open for a 48 hour sampling period. At the time of the sampling, doors were kept closed as was feasible other than normal entry/exit to the rooms and basement. There are no windows in the basement. It was not possible for the HVAC system to be shut down during the testing due to building occupation in other areas. At the end of the 48 hour sample period, sampling canisters were sealed and labeled as per the provided instructions, and samples were shipped to Energy Laboratories in Billings, Montana for gravimetry and radiochemical analysis by gamma spectroscopy using a sodium iodide detector in accordance with EPA Method

E520/5-87-005.

5.2 Radon Sampling Results

The following table provides the sample results for the radon samples collected from the

Wellpinit Service Unit - Clinic basement. Radon samples are reported in picocuries per liter

(pCi/L). The EPA and CDC recommend further testing and/or remedial action if continuous exposure levels reach an Action Level of 4.0 pCi/L. All samples were below the Action Level of

4.0 pCi/L. See Appendix D for laboratory analytical results.

6.0 CONCLUSIONS AND RECOMMENDATIONS

From September 9-11, 2014, Argus Pacific conducted a renovation-level regulated building materials assessment of the Wellpinit Service Unit - Clinic, located at 6203 Agency Loop Road in

Wellpinit, Washington.

6.1 Asbestos

The results of the asbestos assessment conducted at the Wellpinit Service Unit - ClinicWellpinit

Service Unit - Clinic indicate that the following building materials sampled are ACMs or are assumed to contain greater than one percent asbestos.

Asbestos-related work must be performed in compliance with Federal worker protection and environmental protection regulations. See OSHA asbestos regulations and SRCAA Regulation

III, Article 4 for additional information.

6.2 Lead

See Appendix B for results of all on-site XRF testing and corresponding confirmation paint chip sample results.

One-hundred and thirty-six (136) on-site X-Ray Fluorescence Spectrometer (XRF) readings were taken. Two of the XRF readings were above the EPA/HUD “lead-based paint” threshold of 1.0 mg/cm . Twenty-two readings had detectable levels of lead, but at concentrations below the

EPA/HUD threshold.

Based on XRF readings, the paint on the following components contains greater than 1.00 mg/cm lead and is considered lead-based paint according to EPA/HUD and the EPA’s Lead

Renovation, Repair, and Painting Rule (RRP Rule) applies:

Interior gypsum wallboard, west wall in main floor Conference Room (white-painted)

Twenty-two XRF readings had detectable levels of lead, but at concentrations below the

EPA/HUD threshold. In addition, three paints that showed non-detect XRF readings were confirmed via confirmation paint chip sampling to have detectable lead (below the EPA/HUD threshold).

For paint with detectable lead at concentrations below the EPA/HUD “lead-based paint” threshold, Federal OSHA regulations still apply. Workers using respiratory protection and who have received proper training in the handling of lead contaminated materials must be used for any activities (manual scraping, manual/power sanding, general clean-up, demolition, and the use of a heat gun) that may impact areas where lead containing paint is present.

OSHA requires an exposure assessment be conducted during operations that may disturb the lead paint in such a way that the airborne exposure may reach or exceed the Action level of 30 micrograms per cubic meter (µg/m ) or the Permissible Exposure Limit of 50 µg/m

. The worker protection requirements of 29 CFR 1926.62 may apply.

Some of the coatings contained detectable levels of lead. If this building or portions of it will be demolished and disposed of, a toxicity characteristic leachate procedure (TCLP) sample that is representative of the waste stream must be collected and analyzed per the requirements of EPA

40 CFR Part 260. If the results of the TCLP analysis determine the waste to be a "hazardous waste" as defined by 40 CFR Part 260, it must be disposed of accordingly.

The lead sampling and reporting conducted as a part of this assessment may be used to meet the requirements of the Environmental Protection Agency’s Lead; Renovation, Repair, and Painting rule (RRP). Refer to 40CFR745 for additional information.

6.3 Radon

The EPA and CDC recommend further testing and/or remedial action if continuous exposure levels reach an Action Level of 4.0 pCi/L. All samples were below the Action Level of 4.0 pCi/L.

The results of the short-term testing for radon conducted by Argus Pacific in the basement of the

Wellpinit Service Unit - Clinic were all below the Action Level of 4.0 pCi/L.

It is recommended that certain “closed-building conditions” are met during sampling for radon, including keeping windows closed, limiting opening of doors to normal entry/exit, and shut down all fans, HVAC, and air systems. For the sampling conducted by Argus Pacific, all of these conditions were met except for the HVAC shut down, which was not possible at the time of the assessment due to the building being occupied.

7.0 LIMITATIONS

This report presents the results of the regulated building materials assessment of the Wellpinit

Service Unit - Clinic, located at 6203 Agency Loop Road in Wellpinit, Washington. The purpose of the assessment was to identify potential asbestos-containing material and lead-containing coatings, as well as testing for radon in the basement, prior to renovation and for purposes of hazard communication and on-going management. The assessment was limited to the interior, exterior, and roof of the east portion of the building (original 1970 construction). The assessment did not include interior or exterior areas of the building west of the original construction portion.

Regulated building material assessments are non-comprehensive and subject to many limitations, including those presented below. Our assessment has considered risks pertaining to asbestos, lead in coatings, and radon testing; however, this assessment is limited to only those locations and materials assessed. This assessment was not designed to identify all potential concerns or to eliminate all risks associated with renovation, demolition, material removal, construction, or transferring of property title. Evaluation of other risks not specifically described in the Scope of

Work have not been included; for example: structural integrity; engineering loads; electrical;

mechanical; slope stability; building settlement; and evaluation of toxic and hazardous substances in, or in contact with, soil and groundwater. No warranty, expressed or implied, is made.

Argus Pacific has performed the services set forth in the Scope of Work in accordance with generally accepted industrial hygiene practices in the same or similar localities, related to the nature of the work accomplished, at the time the services were performed.

The regulated building materials and conditions presented in this report represent those observed on the dates we conducted the sampling. This sampling is intended for the exclusive use of

Inspection Experts, Inc. for specific application to the referenced property. This assessment does not replace nor can be used as professionally developed construction or demolition plans, specifications, or bidding documents. This report is not a legal opinion.
