Three feet of clean soil will then be added to bring the fill up to the surface level. Once all backfill work is complete, the excavated areas will be restored to the original grade. Some areas will be re-planted with vegetation, while the remaining areas will be covered with stone in preparation for the future parking lot. If any non-soil objects are recovered during the excavation work, these objects will be cleaned and retained for archaeological analysis. EPA expects the soil work to be complete in December 1998.
Design plans for a parking lot at the site are underway.
Construction of the parking lot will begin in the summer of 1999. In the summer of 1997, Chesapeake began design work for addressing contaminated soils outside of the gas holders. SVE utilizes a system of underground wells to pull contaminants out of the soil in the form of a vapor or gas. The vaporized contaminants are then collected and treated. Chesapeake is currently finalizing the field work and design plans for the SVE system.
