EQI Project No. 304165 2

1 INTRODUCTION

A hazardous building material survey (HBMS) was conducted on April 15 and 16, 2025, at the Hawaii Volcanoes National Park, Hilo, Hawaii.

The purpose of the activities under this project was to perform an inspection to identify asbestos containing materials (ACMs); lead-based paints (LBP); and polychlorinated biphenyls (PCBs) that may be encountered during the demolition of the buildings associated with the rehabilitation of the rain shed and water treatment system.

SITE LOCATION

The listed buildings were included in our inspection:

• Building 43

• Building 241

• SAR Building

• Evidence Building

EQI Project No. 304165 3

2 ASBESTOS

Thirty-three samples were collected from suspect asbestos-containing materials.

METHODOLOGY

A visual inspection for suspect ACM and homogeneous areas (areas that have uniform color, texture, and appearance) was conducted. Suspect materials were divided into three Environmental Protection Agency (EPA) categories:

- Surfacing Materials (sprayed or troweled-on materials)

- Thermal Systems Insulations (materials generally applied to various mechanical systems)

- Miscellaneous Materials (any materials which do not fit in the above categories)

Sampling methodology generally followed the procedures presented in EPA 40 CFR 763 Subpart E, Asbestos Containing Materials in School and Hawaii Department of Health (HDOH), Hawaii Administrative Rules (HAR) Titles 11-501 Asbestos Requirements and 11-502 Asbestos Containing Materials in Schools.

RESULTS

Samples were submitted to Hawaii Analytical Laboratory (HAL), LLC, in Honolulu, Hawaii, a National Voluntary Laboratory Accreditation Program (NVLAP) accredited laboratory. The samples were analyzed by polarized-light microscopy (PLM), following EPA Method 40 CFR 763, Appendix E to Subpart E Interim Method of the Determination of Asbestos in Bulk Insulation Samples and EPA 600/R-93-116 Method for Determination of Asbestos in Bulk Building Materials. HAL is also registered to provide asbestos laboratory services in Hawaii under HDOH 11-504 Asbestos Abatement Certification Program.

Based on the laboratory analytical results, asbestos was not identified in the samples. The National Emission Standard for Hazardous Air Pollutants (NESHAP), 40 CFR 61 Part M, defines ACM as those which contain greater than 1% asbestos. In accordance with NESHAP requirements, samples consisting of distinct layers of materials were analyzed and reported separately by the laboratory. A summary of the data is presented in Table 1.

Refer to the accompanying appendices for the laboratory analytical report and photographs.

EQI Project No. 304165 4

3 LEAD

Twenty-five paint film samples were collected from painted or coated materials.

A visual inspection for painted or coated building surfaces was conducted. Sampling methodology generally followed the procedures presented in the U.S. Department of Housing and Urban Development’s document Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing, EPA 40 CFR 745 Lead-Based Paint Poisoning Prevention in Certain Residential Structures, and ASTM E1729 Standard Practice for Field Collection of Dried Paint Samples for Subsequent Lead Determination.

Samples were submitted to HAL, an American Industrial Hygiene Association (AIHA) accredited laboratory with a specific accreditation for lead analysis under the AIHA Environmental Lead Laboratory Accreditation Program. The paint film samples were analyzed by NIOSH Method 7082m, Flame Atomic Absorption Spectroscopy.

Based on the laboratory analytical results, five of the 25 samples exceeded the EPA guidelines for lead in paint. The EPA defines lead-based paint as paint or other coatings containing lead equal to or in excess of 0.5% lead by weight. Lead at concentrations below the EPA guidelines were also detected in various paints/coatings. For the purpose of this report, this paint is identified as paint with lead (PWL), paint having lead concentration greater than the laboratory detection limit but less than 0.5% lead by weight. A summary of the data is presented in Table 2.

Refer to the accompanying appendices for the laboratory analytical report and photographs.

EQI Project No. 304165 5

4 POLYCHLORINATED BIPHENYL LIGHT BALLAST

A visual survey was conducted to identify fluorescent light ballasts (FLBs).

Approximately 53 light fixtures were identified in the buildings. Five representative light fixtures were dismantled to expose the FLBs for inspection.

FLBs manufactured before July 2, 1979, may contain PCBs. The EPA required the manufacturers of FLBs built between July 1, 1978 and July 1, 1998, to mark the ballasts that do not contain PCBs with a label “No PCBs”. If FLBs are not labeled as “No PCBs”, it should be assumed to contain PCBs unless it is known to be manufactured after 1979. FLBs manufactured after 1998 are not required to be labeled. The average life expectancy of a fluorescent light ballast is approximately 10-15 years.

The “No PCBs” label was observed on the FLBs that were inspected. The fluorescent light tubes are presumed to contain mercury.

EQI Project No. 304165 6

5 SUMMARY

ASBESTOS

Asbestos-containing material was not identified in this inspection. However, it should be noted that the underground cement water piping was inaccessible at the time of the inspection. This material must be assumed to be ACM unless tested and proven to be otherwise.

LEAD

The listed LBPs were identified.

Color Location Condition Off-white over gray B43, wood window frame Poor

Off-white B43, corrugated metal wall siding (exterior) Poor Off-white over gray B241, wood beam, post and trusses Fair

Paints with lead were also identified, see Table 2. Prior to the disturbance of any LBP and PWL, the contractor’s employees disturbing the painted material must be informed that it contains lead and must conduct all lead disturbance work in accordance with Occupational Safety and Health Administration (OSHA) 29 CFR 1926.62 Lead. If any untested paints are disturbed, they should be assumed to contain lead.

If lead paint chip or waste is generated during the demolition work, composite samples of the generated waste must be collected for Toxicity Characteristic Leaching Procedure (TCLP) analysis for waste disposal characterization. EPA 40 CFR Part 261, Identification and Listing of Hazardous Waste allows a maximum concentration of lead contaminant by TCLP at 5.0 mg/L.

TCLP results exceeding the 5.0 mg/L threshold requires the material to be disposed of as hazardous waste. Results below this threshold allow for the lead waste to be disposed of as construction debris. Note that painted metal components are exempt from TCLP testing if recycled.

POLYCHLORINATED BIPHENYLS IN LIGHT BALLASTS

PCB ballasts were not identified. However, the fluorescent light tubes are known to contain measurable amounts of mercury and should be collected for disposal or recycling in accordance with HDOH and EPA regulations.

General Comments The bulk sample[s] analysis subject of this analytical report were conducted in general accordance with the procedures outlined in the United States Environmental Protection Agency’s “Interim Method for the Determination of Asbestos in Bulk Insulation Samples” (EPA-600/M4-82- 020, Dec. 1982) and / or “Method for Determination of Asbestos in bulk Building Materials” (EPA-600/R-93-116, July 1993). The analysis of each bulk sample relates only to the material examined, and may or may not represent the overall composition of its original source. Floor tile and other resinously bound materials, when analyzed by the EPA methods referenced above may yield false negative results because of limitations in separating closely bound fibers and in detecting fibers of small length and diameter. Gravimetric treatment, which HAL does not offer, may also be appropriate for certain NOB (non-friable organically bound) materials. Unless specifically requested by clients, NOB samples can be subcontracted to a NVLAP accredited lab, or else, they will be analyzed by HAL using regular PLM technique. In addition, alternative methods of identification, including Transmission Electron Microscopy (TEM) may or may not be applicable. We utilize calibrated visual area estimation on a routine basis and do not conduct point counting unless specifically requested to do so. Estimated error for the visual determinations presented are 75% relative (<1 to 10%), 65% relative (11 to 19%), 50% relative (20 to 34%); 40% relative (35 to 50%), 35% relative (51 to 60%), and 25% relative (>60% v/v). We will not separate layers which in our opinion are not readily discernable. This report is not to be duplicated except in full without the expressed written permission of Hawaii Analytical Laboratory. This report must not be used by the client to claim product certification, approval or endorsement by NVLAP, NIST or any agency of Federal Government. Unless otherwise indicated, the sample condition at the time of receipt was acceptable.

Results and Symbols Definitions > This testing result is greater than the numerical value listed.

< This testing result is less than the numerical value listed.

None Detected = asbestos was not observed in the sample. If trace amount of asbestos was detected below our quantifiable limits of 1.0%, <1% (trace) would be indicated and the asbestos type listed. Point counting, where applicable, are recommended to improve accuracy.
