Proposed locations of the SVE wells are shown on Figure 3. The project will consist of the tasks listed below. • Site Health and Safety. • Utility Clearance and Notification. • Access Agreements and Permitting. • Horizontal Soil Borings and SVE Well Installation. • Connection to Remediation System. • Soil and Water Disposal. • Report.

The Site-Specific Health and Safety Plan will be reviewed by the field staff and contractors before beginning field operations at the site. Utility Clearance and Notification. Prior to drilling, SECOR will mark the location of each soil boring and use a private utility locator to clear each location. Underground Service Alert(USA)will be called to allow the local underground utility companies to identify the location of any utilities in the area of the proposed work and as-built plans of the apartment buildings will be obtained and reviewed to avoid underground utilities located beneath the apartment buildings.
