Hazardous Materials Survey Report RMC Architects Port of Skagit SWIFT Center – Douglas Building Sedro-Woolley, Washington

<br />1 INTRODUCTION
<br />1.1 Project Background
<br />PBS Engineering and Environmental Inc. (PBS) performed a hazardous materials survey of the Douglas
<br />Building at the Port of Skagit SWIFT Center in Sedro-Woolley, Washington in conjunction with the planned
<br />demolition of the structure. The intent of this investigation is to ensure compliance with applicable regulatory
<br />requirements that a "good faith inspection” for asbestos-containing materials (ACMs) be performed prior to
<br />renovation and restoration activities.
<br />
<br />All accessible areas associated with the project were inspected for the presence of ACMs, lead-containing
<br />paint (LCP), mercury containing components, and polychlorinated biphenyls (PCBs). PBS based its survey on
<br />drawings completed by Decker and Christensen Architects, dated April 25, 1960. 1.2 Building Descriptions
<br />The Douglas Building is a three-story concrete structure with a flat, ballasted roof, built in 1961. Interior floor finishes include: 9” vinyl floor tile, 12” vinyl floor tile, sheet vinyl flooring, ceramic tile, carpet, and concrete.
<br />Walls are typically concrete with plaster and a skim coat finish and ceiling feature 12” acoustical ceiling tiles which are glued to concrete. The exterior of the building is concrete, and windows are typically metal framed.
<br />1.3 Survey Process Accessible areas included in the project scope were inspected by Asbestos Hazard Emergency Response Act
<br />(AHERA) Certified Building Inspectors Kaitlin Soukup (Cert. No. 179143, Exp. 10/14/2021), Claire Tsai (Cert. No. IRO-21-7316B, Exp. 1/18/2022), Toan Nguyen (Cert. No. IN-219206B, Exp. 4/14/2022) from August 18-30,
<br />2021. This inspection included the basement, ground floor and 1st Floor of the central core and the entire east wing. From October 7-9, 2023. Janet Murphy (Cert. IMR-23-8300A 03/02/2024PBS inspect the 2nd Floor of the
<br />central core and west wing. Inaccessible areas were not inspected. These include those areas requiring
<br />selective demolition, fall protection, or confined space entry protocols to gain access.
<br />
<br />When observed, suspect materials were sampled. All samples were assigned a unique identification number
<br />and transmitted for analysis to Seattle Asbestos Test (NVLAP #201057-0) under chain-of-custody protocols.
<br />Samples were analyzed according to EPA Method 600R-93/116 using Polarized Light Microscopy (PLM), which has a reliable limit of quantification of 1% asbestos by volume.
<br />
<br />PBS endeavored to determine the presence and estimate the condition of suspect materials in all inaccessible areas included in the scope of work. While PBS has endeavored to identify the ACMs that may be found in
<br />concealed locations, additional unidentified ACMs may exist. 2 FINDINGS
<br />2.1 Asbestos-Containing Materials (ACMs)
<br />The following materials were determined to contain greater than 1% asbestos as part of this investigation.
<br />• 9” vinyl floor tile (red, beige, gray, white, brown) and associated black mastic – throughout West
<br />and East Wings, Administration Corridor 801, 827, Staff Office 822, Medical Library 812, Waiting Area
<br />808, Janitors Closet 816 A and B, Vault 809, – approximately 30,710 SF;
<br />• 9” vinyl floor tile (red, beige, gray, white, brown) and associated black mastic (concealed) under
<br />shower and tub inserts in Bathrooms throughout – approximately 300 SF;
<br />• 9” vinyl floor tile (red, beige, gray, white, brown) and associated black mastic (concealed) under
<br />carpet in Rooms 806, 810, 811, 813, 820, 819, 818, 817, 824, 825, 826, – approximately 7,200 SF;
