Limited Phase II Site Assessment Work Plan BORDEN TRUST PROPERTY 65 & 67 East loth Street, Tracy, California 1.0. INTRODUCTION Advanced GeoEnvironmental, Inc. (AGE) has prepared this, Limited Phase 11 Site Assessment Work Plan for the property located at 65 & 67 East loth Street, Tracy, California (site). The proposed scope of work includes the advancement of three (3) borings for the collection of soil, grab groundwater and soil-vapor samples. The location of the site is illustrated in Figure 1. A site plan depicting the proposed boring locations is presented in Figure 2. 2.0. BACKGROUND AGE completed a Phase I Environmental Site Assessment for the subject property. Historical records indicated an underground storage tank (UST) was located on the property. However, no records of removal or sampling were identified. Furthermore, a former dry-cleaning facility was located nearby. Based upon the historical UST and nearby former dry-cleaner, AGE has recommended the performance of a ground-penetrating radar (GPR) survey and limited site assessment to evaluate if a tank/tank cavity is present and if the subsurface has been impacted by historical and adjacent site use. 3.0. SCOPE OF WORK Based on historical use, site assessment has been recommended to determine if petroleum constituents have impacted the subsurface at the site. For this investigation, AGE proposes to advance one (1) soil boring for the collection of soil and a shallow grab groundwater sample. Additionally, AGE proposes to collect a total of two (2) soil- vapor samples at each end of the suspected area of the former UST. The proposed scope of work includes the following tasks: • Permitting and pre-field work activities. • Soil boring advancement and sample collection. • Grab groundwater sample collection. • Soil boring advancement for installation of temporary soil-vapor sampling wells.
