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:

EQI Project No. 304165

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
