Phase II Sampling and Analysis Plan SOP-2—Drilling and Sampling Port of Stockton-Rail and Bridge,Stockton,CA FN 6.4 Structural Elements Sampling (Lead-Based Paint and Asbestos-Containing Materials) 6.4.1 Field Sampling HDR will seek authorization to perform field sampling to screen structural elements for hazardous materials. Prior to sampling, HDR will conduct limited pre-field site surveillance activities and prepare for site sampling. Pre-field activities will include: • Mapping the sampling location or structure, • Reviewing satellite imagery of the sampling location or structure to determine access and encroachment needs, • Assessing structure construction • Verifying required sampling methods • Identifying any potential hazards. HDR will use this information to update its site-specific HASP and Sampling and Analysis Plan (SAP)for the Project. HDR will then secure rights-of-entry and confirm if permits are needed to conduct destructive sampling of bridge structure for asbestos-containing materials (ACM) and lead- based paint (LBP). HDR will revise its SAP to meet the needs and scope of the survey, focusing on the types of equipment, safety, limitations identified in permits, and methods needed to perform destructive sampling of suspected ACM and surfaces suspected of having LBP. HDR will conduct a field reconnaissance to visually assess the existing conditions in the vicinity of the Project site with respect to the potential for hazardous materials or hazardous materials impacts to the proposed Project. Because the existing structure will undergo demolition and replacement and has the potential to contain LBP and/or ACM, HDR will collect and analyze samples of suspected ACM and/or LBP from the existing structure. HDR will document the sample locations with photographs and sketches. Samples will be submitted to an accredited laboratory to be analyzed by polarized light microscopy and paint chip analysis. HDR will conduct the survey under the direction of a Certified Asbestos & LBP Consultant. 6.4.2 Structural Elements Assessment Report HDR will prepare a Structural Elements (Asbestos and Lead)Assessment Report (SEAR) and incorporate materials sampling and analytical tests elements of the bridge. The Asbestos and Lead Survey Report will be prepared in compliance with the federal National Emission Standards for Hazardous Air Pollutants (NESHAP) and El Dorado County Air Quality Management District (EDCAQMD) regulations for asbestos and in compliance with the U.S. Environmental Protection Agency (EPA) and Caltrans regulations for lead hazards. The SEAR will include: • The results of limited hazardous materials assessment based on a literature review and visual site reconnaissance • The analytical test results of suspected ACM and/or LBP from the existing structure. 2-11
