Consulting Services Agreement between City of San Leandro and Gates & Associates, Inc for Staff Augmentation Exhibit A – Page 26 of 31 ● Soil and sediment samples will be submitted to a state-accredited laboratory for analysis of the following compounds on a discrete basis. ○ CAM 17 Metals by Environmental Protection Agency (EPA) Method 6010/7471 ○ Volatile organic compounds (VOCs) by EPA Method 8260B ○ Semi-volatile organic compounds (SVOCs) by EPA Method 8270 SIM ○ Asbestos by CARB 435A (400-point count) ● A sampling and testing report will be prepared, summarizing the sampling activity and laboratory analytical results. Laboratory results will be compared to established soil screening levels to determine appropriate soil handling, reuse, or disposal. If the initial laboratory analytical results indicate exceedances of certain compounds, it is conceivable that additional sampling and/or laboratory analyses may be necessary. However, additional sampling or laboratory analyses beyond the scope mentioned above is not included in the fee and can be negotiated after the initial test results come in. Permitting fees are included for in water testing, however the fees for sedimentation testing are currently not included. Sedimentation testing will require clarification from the Waterboard to accurately provide a fee as the location of samples, number of samples, depths, and required sediment compounds to be tested are unknown. There is a potential of encountering contaminated soils at fuel storage area, as well as other areas at the site. ● Preparation of an SMP to provide appropriate protocols to be followed if impacted media are encountered during demolition and/or grading activities ○ Review of previous environmental sampling data and data collected during the proposed additional sampling activities (See Task 2.4) will inform the development of an SMP ● SMP will Provide guidelines for additional testing to identify full extent of contamination encountered during demolition and/or grading activities ● SMP will provide specifications for typical disposal characterization activities ○ Final disposal characterization requirements will be determined based on desired reuse scenario and/or receiving facility requirements ● SMP will identify potential disposal facilities ● SMP will discuss Import fill acceptance criteria for the Site ● SMP Implementation - Provide as-needed observation and sampling activities during demolition and grading - Scope and fee to be determined based on field conditions ● SMP Completion Report - Fee to be determined based on field conditions and extent of SMP implementation activities performed throughout the course of construction.
