Hazardous Materials Survey Report RMC Architects Port of Skagit SWIFT Center – Douglas Building Sedro-Woolley, Washington <br /> <br /> 6 October 30, 2023 PBS Project 41140.017 <br />2.3 Mercury-Containing Components All fluorescent light tubes are presumed to contain mercury. Approximately 3,704 four-foot, 500 two-foot light <br />tubes, and 660 compact fluorescent bulbs were observed in the accessible areas of the building. <br /> <br />2.4 PCB-Containing Components <br />PBS used a Phillips Ballast Checker to inspect representative fluorescent light fixture ballasts throughout the <br />work areas. PBS did not observe magnetic ballasts. All ballasts should be inspected prior to being disposed of. <br /> 3 RECOMMENDATIONS <br />3.1 Asbestos-Containing Materials (ACMs) PBS recommends that all ACMs that may be impacted by project activities be removed prior to impact. A qualified Washington State licensed asbestos abatement contractor should be employed to remove all such <br />ACM according to applicable local, state, and federal regulations. <br /> <br />The possibility exists that additional suspect ACMs may be present in concealed locations, including but not <br />limited to, equipment, wall and ceiling cavities, and utility chases. These materials may include, but are not <br />limited to, waterproofing membrane, internal gaskets, caulking and sealants of heating, ventilation, and air <br />conditioning (HVAC) equipment and construction adhesives and wall mastics. In the event that suspect ACMs <br />is uncovered during construction, contractors should stop work immediately and inform the owner promptly for confirmation testing. All untested materials should be presumed asbestos-containing or tested for <br />asbestos content prior to impact. <br />3.2 Lead-Containing Components Representative interior and exterior painted coatings were found to contain lead. Impact of painted surfaces with detectable concentrations of lead requires construction activities to be performed according to <br />Washington State Department of Labor and Industries (L&I) regulations for Lead in Construction. Impact of painted surfaces with detectable concentrations of metals in building materials and products requires <br />construction activities to be performed according to Washington Administrative Code (WAC) 296-155-176 Lead in Construction and WAC 173-303 Dangerous Waste Regulations. <br /> Painted coatings may exist in inaccessible areas of the work area or in secondary coatings. Any previously unidentified painted coatings not sampled should be considered lead containing until sampled and proven <br />otherwise. Dust control and housekeeping is crucial in preventing worker and occupant exposures. <br />3.3 Mercury-Containing Components Fluorescent lamps are known to contain mercury vapor. PBS recommends that all fluorescent lamps be carefully handled and recycled/disposed of in accordance with the contract documents and applicable <br />regulations during construction activities. Breakage of lamps should be avoided to prevent potential exposures to mercury. L&I requires specific training, handling, engineering controls, and disposal practices <br />when performing this work. All waste shall be handled in accordance with WAC 173-303. <br />3.4 PCB-Containing Components PBS recommends all light ballasts be inspected prior to disposal. Magnetic ballasts should be presumed to contain PCBs and properly removed, stored, transported and disposed of in accordance with WAC 173-303 <br />Dangerous Waste Regulations and 40 CFR Part 761 Subpart D. Electronic ballasts do not contain PCBs and can be disposed of as general debris in compliance with applicable codes and endpoint facility requirements. <br />Please do not hesitate to contact us if you have any questions regarding this report or require additional <br />information.
