EXECUTIVE SUMMARY

Jacobs Engineering Group retained Terracon Consultants (Terracon) to conduct a regulated building materials assessment of the Heart O The Hills Ranger Station, located at Olympic National Park, 48.037624,-123.430192 in Port Angeles, Washington.

Terracon’s representative, Mr. Jacob Iverson, conducted the assessment on November

5, 2019. The scope of the services provided is described in Terracon Proposal Number

P81197566 dated October 10, 2019.

Terracon assessed the building for the following regulated building materials:

• Asbestos-containing materials (ACM);

• Assumed asbestos-containing materials;

• Lead-containing coatings (paints);

• Mercury-containing light tubes, switches, and thermostats;

• Suspected high-intensity discharge (HID) lamps; and

• Suspected PCB-containing fluorescent light ballasts.

Twenty bulk samples of suspect asbestos-containing materials were collected and analyzed using Polarized Light Microscopy (PLM). None of the materials were found to contain greater than one percent asbestos and none of the materials were assumed to contain asbestos. In addition, four materials were visually assessed and determined to be non-suspect.

Four paint chip samples were collected and analyzed for total lead content. Three of the paint chip samples were found to contain detectable levels of lead.

Mercury-containing fluorescent light tubes were identified in the building. HID lamps were identified on the exterior of the building. Light ballasts associated with fluorescent light fixtures were assumed to be PCB-containing.

2.0 PROJECT BACKGROUND

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

Heart O The Hills Ranger Station located at Olympic National Park, 48.037624,-

123.430192 in Port Angeles, Washington. The purpose of the assessment was to identify potential asbestos-containing material, lead-containing coatings, PCB-containing light ballasts, and mercury-containing components prior to building demolition and for purposes of hazard communication and on-going management. The assessment included the interior, exterior, and roof.

This assessment will assist Jacobs Engineering Group with communicating the presence of regulated building materials, and the presence, location, and quantity of ACM to employees, vendors, and contractors working in the project area and to meet the requirements for an asbestos survey for the Olympic Region Clean Air Agency (ORCAA) and a good faith inspection as required by Washington State Department of Labor and

Industries’ Division of Occupational Safety and Health (DOSH) regulations prior to building 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 Terracon inspector:

• Mr. Brad Metler, National Parks Service

2.2 Building Description

The Heart O The Hills Ranger Station is located at Olympic National Park, 48.037624,-

123.430192 in Port Angeles, Washington. The building was constructed at an unknown date and contains approximately 500 square feet of interior floor space. The building consists of two sections with a drive through area in the middle. The building consists of an office, a bathroom, and a storage closet.

The building is wood construction that sits on a concrete foundation. The roof consists of wood shingles above an asphaltic vapor barrier. The building is heated by a forced air heating, ventilating, and air conditioning (HVAC) system. Interior floors consist of concrete, vinyl floor sheeting on concrete, and wood decking. Interior walls and ceilings consist of wood.

The observed piping was not insulated. The observed HVAC ducting is insulated with foil-wrapped fiberglass.

3.0 ASBESTOS ASSESSMENT

3.1 Building Assessment

Mr. Iverson, an Asbestos Hazard Emergency Response Act (AHERA)-accredited building inspector (Certification 172933, expiration date: 4/26/2020) from Terracon, performed the sampling on November 5, 2019. Terracon’s inspector collected twenty 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.

Jacobs Engineering Group Terracon #81197566

• 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 NVL Laboratories in Mountlake Terrace, Washington. Samples were analyzed via polarized light microscopy (PLM) in accordance with EPA/600/R-93/116. NVL

Laboratories is accredited to perform PLM analysis by the National Institute of Standards and Technology National Voluntary Laboratory Accreditation Program (NVLAP).

Jacobs Engineering Group Terracon #81197566

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 Occupational Safety and Health Administration (OSHA), EPA, and applicable state and local 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

Homogeneous areas of suspected lead-containing coatings (paints) were identified and sampled in accessible areas throughout the Heart O The Hills Ranger Station located at

Olympic National Park, 48.037624,-123.430192 in Port Angeles, Washington.

Homogeneous painted surfaces were defined by substrate, application, and color.

4.1 Sampling Methodology

Paint chip samples were collected to the substrate to ensure that all layers present on the substrate were included in the laboratory analysis. Each sample was collected and stored in a heavy-duty, self-sealing plastic bag and delivered to NVL Laboratories in Seattle, Washington. Samples were analyzed via Atomic Absorption Spectrophotometry in accordance with Method EPA 7000B. NVL Laboratories in Seattle, Washington is accredited by the American Industrial Hygiene Association (AIHA) for lead analysis.

4.2 Lead Sampling Results

Four paint chip samples were collected and analyzed for lead. Three samples had reportable levels of lead. The results of the analyses are presented in Table 4.2-1.

5.0 OTHER REGULATED BUILDING MATERIALS

5.1 Methodology – Universal Wastes

An inventory of fluorescent light tubes, HID lamps, and potential PCB-containing ballasts was conducted in accessible areas of the project.

Where fluorescent light fixtures were accessible, the ballast covers were removed, and the ballast labels were visually examined. Different types of fluorescent fixtures were distinguished by shield shape, fixture dimension, diffuser type, and the manner in which the ballast covers were connected to the fixture.

Where fluorescent light fixtures could not be visually examined, the number of potential

PCB-containing ballasts in fixtures was estimated based on the following assumptions:

• Each multiple light tube fluorescent fixture contains one ballast for every pair of light tubes.

• All light ballasts are assumed to contain PCBs unless the manufacturer’s label indicates they are electronic ballasts.

Where high intensity discharge lamps could not be accessed or examined, the following assumptions were made:

• Each HID lamp contains one ballast;

• Each HID lamp contains a minimum of one mercury bulb, sodium vapor bulb, or metal halide bulb.

Jacobs Engineering Group Terracon #81197566

5.2 Results

Fluorescent light tubes were observed throughout the building interior. HID lamps are present on the building exterior. Light ballasts associated with fluorescent light fixtures were assumed to be PCB-containing. Fluorescent light tubes, PCB ballasts, and HID lamps were identified in the following quantities:

6.0 CONCLUSIONS AND RECOMMENDATIONS

On November 5, 2019, Terracon conducted a regulated building materials assessment of the Heart O The Hills Ranger Station located at Olympic National Park, 48.037624,-

123.430192 in Port Angeles, Washington.

6.1 Asbestos

No asbestos was detected in the materials sampled.

Additional suspect ACMs may be present in areas not assessed or that were inaccessible or concealed. These spaces include, but are not limited to, below wood decking, 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, Terracon recommends that a thorough assessment of these spaces be conducted at that time to identify and confirm the presence or absence of additional suspect ACMs. Until then, all such unidentified materials must be treated as assumed ACMs in accordance with applicable federal, state, and local regulations.

6.2 Lead

Three paints sampled and analyzed contained detectable levels of lead.

The Washington State Department of Labor and Industries 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/m3) or the Permissible Exposure Limit of 50 µg/m3. The worker protection requirements of WAC 296-155-176 "Lead in Construction" may apply.

Jacobs Engineering Group Terracon #81197566

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 WAC 173-303. If the results of the TCLP analysis determine the waste to be a "dangerous waste" as defined by WAC 173-303, it must be disposed of accordingly.

The lead paint chip sampling and reporting conducted as a part of this assessment may not 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 Other Regulated Building Materials

Fluorescent light tubes, HID lamps, switches, and thermostats may contain mercury.

Fluorescent light ballasts and HID lamp ballasts may contain PCBs. In Washington State, even ballasts labeled with "No PCBs" may have regulated amount of PCBs and therefore should be handled in accordance with Washington Department of Ecology requirements.

Employers must inform their employees of mercury and PCB hazards in accordance with

WAC 296-800-170.

Fluorescent light tubes, HID lamps, switches, and thermostats light ballasts must be removed and recycled or disposed of prior to building demolition as per 40 CFR 262, 40

CFR 265, and WAC 173-303.

7.0 LIMITATIONS

This report presents the results of the regulated building materials assessment conducted at the Heart O The Hills Ranger Station located at Olympic National Park, 48.037624,-

123.430192 in Port Angeles, Washington. The assessment was for the purposes of identifying ACM, lead-containing paint, mercury-containing components, PCB ballasts, and HID lamps prior to demolition.

Appendix A Asbestos Laboratory Analytical Results

Matt Macfarlane, Asbestos Lab Supervisor

Client Project: 81197566 Location: Heart O' The Hills

Dear Ms. Anderson, Enclosed please find test results for the 20 sample(s) submitted to our laboratory for analysis on 11/6/2019.

Examination of these samples was conducted for the presence of identifiable asbestos fibers using polarized light microscopy (PLM) with dispersion staining in accordance with both EPA 600/M4-82-020, Interim Method for the Determination of Asbestos in Bulk Insulation Samples and EPA 600/R-93/116 Method for the Determination of Asbestos in Bulk Building Materials.

For samples containing more than one separable layer of materials, the report will include findings for each layer (labeled Layer 1 and Layer 2, etc. for each individual layer). The asbestos concentration in the sample is determined by calibrated visual estimation.

For those samples with asbestos concentrations between 1 and 10 percent based on visual estimation, the EPA recommends a procedure known as point counting (NESHAPS, 40 CFR Part 61). Point counting is a statistically more accurate means of quantification for samples with low concentrations of asbestos.

The detection limit for the calibrated visual estimation is <1%, 400 point counts is 0.25% and 1000 point counts is 0.1%

Samples are archived for two weeks following analysis. Samples that are not retrieved by the client are discarded after two weeks.

Thank you for using our laboratory services. Please do not hesitate to call if there is anything further we can assist you with.

Sincerely, Enc.: Sample Results

21905 64th Avenue W, Suite 100 Mountlake Terrace, WA 98043

Enclosed please find the test results for samples submitted to our laboratory for analysis.

Preparation of these samples was conducted following protocol outlined in EPA Method SW 846 -3051 unless stated otherwise. Analysis of these samples was performed using analytical instruments in accordance with U.S. EPA, NIOSH, OSHA and other ASTM methods.

For matrix materials submitted as paint, dust wipe, soil or TCLP samples, analysis for the presence of total metals is conducted using published U.S. EPA Methods. Paint and soil results are usually expressed in mg/Kg which is equivalent to parts per million (ppm). Lead (Pb) in paint is usually expressed in mg/Kg (ppm) , Percent (%) or mg/cm2 by area. Dust wipe sample results are usually expressed in ug/wipe and ug/ft2. TCLP samples are reported in mg/L (ppm). For air filter samples, analyses are conducted using NIOSH and OSHA Methods. Results are expressed in ug/filter and ug/m3. Other matrix materials are analyzed accordingly using published methods or specified by client. The reported test results pertain only to items tested and are not blank corrected.

For recent regulation updates pertaining to current regulatory levels or permissible exposure levels, please call your local regulatory agencies for more details.

This report is considered highly confidential and will not be released without your approval.

Samples are archived for two weeks following analysis. Samples that are not retrieved by the client are discarded after two weeks.

Thank you for using our laboratory services. if you need further assistance please feel free to call us at 206-547-0100 or 1-888-NVLLABS.
