01 Sampling and Analysis Plan Port of Stockton—Rail and Bridge,Stockton,CA spans the San Joaquin River and is scheduled for replacement; therefore, structural elements of the bridge will be collected and analyzed for LBP and ACM. The Phase II ESA will be performed in general accordance with American Society for Testing Materials (ASTM) International E 1903-19 Standard Practice for Environmental Site Assessments: Phase 11 Environmental Site Assessment Process. In addition to the SAP, a site-specific Health and Safety Plan (HASP)will be prepared for the proposed field work activities. 2 Sampling Rationale The Site locations chosen for sampling of soil, groundwater, LBP, or ACM, were based on a review of information including. • The Phase I ESA (HDR, 2023)to verify whether the Site or adjacent properties were identified as RECs, HRECs, or CRECs. • If RECs, HRECs, or CRECs were identified in soil or groundwater that will be disturbed during Project construction. • If documented soil or groundwater contamination is present, specific requirements for construction worker health and safety, waste characterization, and disposal/discharge per regulatory standards. • The bridge structure may have a potential to contain ACM and LBP, based on construction information and age. • If current and/or historical railroad use may have contaminated the Site with petroleum hydrocarbons or metals, soil samples will be analyzed for these constituents of concern (COC). A soil and groundwater sampling location summary are provided in Table 1.1. 2.1 Health and Safety A site-specific Health and Safety Plan (HASP) has been prepared to establish overall site operating procedures, safety guidelines and contingency plans for all proposed work to be performed on the Site. A copy of the HASP is included in Appendix A of this Work Plan. The HASP will be revised if Site conditions change during planning or field work. The HASP will apply to all personnel who are involved with site assessment activities at the Site. All work will be conducted in compliance with applicable Occupational Safety and Health Administration (OSHA) regulations, including 29 Code of Federal Regulations (CFR) 1910 (General Industry Standards), and 29 CFR 1926 (Construction Industry Standards). All personnel who will be directly involved in the sampling activities will have received the appropriate hazardous waste site worker and e-RAILSAFE training. In addition, all personnel will be trained in OSHA Hazwoper health and safety procedures, as well as quality assurance (QA) and quality control (QC) procedures. The railroad track area is active; therefore, track protection is required. September 8,2023 1 2
